Diagnosis, treatment and maxillofacial rehabilitation in rhinocerebral mucormycosis patient: A case report and review of the literature.
Mucormycosis is an aggressive, rare and opportunistic infectious disease, with a high mortality rate. Etiologic agents are filamentous fungi, and infection among humans normally occurs through spore inhalation. A 61-year-old male individual, presenting left eye amaurosis, dark epistaxis, hyperalgesia and malodor underwent clinical examination, which detected ulcerative lesion and wide bone exposure in the hard palate and alveolar ridge. Direct microbiological examination, microbiological culture and lesion biopsy were performed. Non-septate smooth fungal hyphae forming right angles with each other were observed through the direct microbiological examination. Microbiological culture revealed fast-growing fungal colonies with cottony texture, identified as Rhizopus sp. Histopathological examination exhibited necrosis areas, intense mononuclear inflammatory infiltrate and bulky hyphae, thus concluding the mucormycosis diagnosis. Amphotericin B antifungal therapy and surgical intervention were adopted as treatment. The patient was then rehabilitated with maxillofacial prosthesis, subsequently to the healing of the surgical wound.

Cryptococcal fungemia and Mycobacterium haemophilum cellulitis in a patient receiving ruxolitinib: a case report and literature review.
Ruxolitinib is a novel oral Janus kinase inhibitor that is used for treatment of myeloproliferative diseases. It exhibits potent anti-inflammatory and immunosuppressive effects, and may increase the risk of opportunistic infections. Here, we report a rare case of Cryptococcus neoformans and Mycobacterium haemophilum coinfection in a myelofibrosis patient who was receiving ruxolitinib.. A 70-year-old Thai man who was diagnosed with JAK2V617F-mutation-positive primary myelofibrosis had been treated with ruxolitinib for 4 years. He presented with cellulitis at his left leg for 1 week. Physical examination revealed fever, dyspnea, desaturation, and sign of inflammation on the left leg and ulcers on the right foot. Blood cultures showed positive for C. neoformans. He was prescribed intravenous amphotericin B deoxycholate with a subsequent switch to liposomal amphotericin B due to the development of acute kidney injury. He developed new onset of fever after 1 month of antifungal treatment, and the lesion on his left leg had worsened. Biopsy of that skin lesion was sent for mycobacterial culture, and the result showed M. haemophilum. He was treated with levofloxacin, ethambutol, and rifampicin; however, the patient eventually developed septic shock and expired.. This is the first case of C. neoformans and M. haemophilum coinfection in a patient receiving ruxolitinib treatment. Although uncommon, clinicians should be aware of the potential for multiple opportunistic infections that may be caused by atypical pathogens in patients receiving ruxolitinib.

Geotrichum capitatum Invasive Infection Early After Liver Transplant.
Geotrichum capitatum is a rare fungal pathogen that has infrequently affected immunocompromised patients with onco-hematologic diseases. Geotrichum capitatum invasive infection has been associated with poor prognosis, with a mortality rate ranging from 50% to 90%. Here, we report the first case of Geotrichum capitatum invasive fungal infection in a liver transplant recipient from an unrelated deceased donor, who was effectively treated with amphotericin B and voriconazole. We also reviewed the available literature in the field.

Sporotrichosis in renal transplant patients: two case reports and a review of the literature.
Sporotrichosis is a rare fungal infection in transplant patients; among these patients, it occurs mostly in renal transplant patients. Sporothrix schenkii is the primary pathogen responsible. A high index of suspicion is required to make the diagnosis keeping important differential diagnoses in mind. History of trauma through recreational or occupational exposure to the fungus may assist in making the diagnosis. Treatment is difficult, with long-term use of potentially nephrotoxic and cytochrome P450 inhibitor antifungal agents leading to potential calcineurin inhibitors toxicity. We describe two renal transplant patients presenting with distinct sporotrichosis infection: "Case 2" being only the second reported case ever of meningeal sporotrichosis. We subsequently review the general aspects of sporotrichosis, specifically in renal transplant patients as described in the medical literature.. Case 1, a 43-year-old mixed ancestry male patient presented with a non-healing ulcer on the left arm for 1 year, he was diagnosed with cutaneous sporotrichosis and was successfully treated with itraconazole monotherapy. Case 2, a 56-year-old mixed ancestry male patient presented with a slow decline in functions, confusion, inappropriate behavior, rigors and significant loss of weight and appetite over the past 4 months, he was diagnosed with meningeal sporotrichosis and was successfully treated with a combination of deoxycholate amphotericin B and itraconazole.. Physicians taking care of renal transplant patients should have a high index of suspicion for sporotrichosis infection particularly when conventional therapy for common conditions fails. Susceptibility testing is recommended to identify the most effective antifungal agent and its dose. The slow nature of growth of Sporothrix schenkii necessitates patients to be on amphotericin B until the time results are available. Finally, there is a need to be aware of potential drug-drug interactions of the azoles with calcineurin inhibitors and the required dose adjustments to prevent therapy related adverse events.

Cryptococcus albidus Fungemia in an Immunosuppressed Child: Case Report and Systematic Literature Review.
Cryptococcus albidus, synonymous with Naganishia albida, rarely causes opportunistic infection in immunocompromised individuals. Its clinical features, particularly in children, are not well defined. Here, we report a case of C albidus fungemia in an immunosuppressed child; we also present results of a systematic review, for which we searched PubMed, Embase, and Web of Science using the keywords "cryptococcus" and "albidus." Our goal was to describe the spectrum of disease, diagnostic approaches, therapies, and outcomes. We identified 20 cases of invasive infection, only 2 of which involved children, and 7 cases of noninvasive infection. The reports originated in the Americas, Europe, and Asia. Of those with invasive infection, 16 (80%) patients had an underlying chronic disorder or had received immunosuppressive therapy, 8 (40%) had fungemia, and 6 (30%) had a central nervous system infection. The attributable case fatality rate was 40%. C albidus is an opportunistic yeast that can rarely cause life-threatening fungemia and central nervous system infection in individuals of any age, especially those who are immunocompromised.

Disseminated Pulmonary with Isolated Muscular Mucormycosis in an Acute Myeloid Leukemia Patient: A Case Report and Literature Review.
BACKGROUND Mucormycosis is a serious, potentially fatal fungal infection caused by species in the Mucorales order. Together with candidiasis and aspergillosis, it is one of the most significant fungal infection that carries a high rate of mortality. Early detection and initiation of antifungal therapy with adequate surgical debridement improves the clinical outcome. CASE REPORT We describe a case of mucormycosis in a patient with acute myeloid leukemia who developed disseminated lung disease with muscular involvement without any cutaneous manifestation. Successful treatment was achieved with surgical debridement, amphotericin B lipid-complex and posaconazole step-down therapy. CONCLUSIONS Mucormycosis can present in various clinical scenarios. Key to diagnosis depends on tissues diagnosis from the affected system, as was done with lung and muscle biopsy in our patient. Clinicians should maintain high suspicion for early diagnosis and prompt treatment.

Clinical diversity of invasive cryptococcosis in AIDS patients from central China: report of two cases with review of literature.
Although antiretroviral therapy (ART) has greatly improved the prognosis of acquired immunodeficiency syndrome (AIDS) patients globally, opportunistic infections (OIs) are still common in Chinese AIDS patients, especially cryptococcosis.. We described here two Chinese AIDS patients with cryptococcal infections. Case one was a fifty-year-old male. At admission, he was conscious and oriented, with papulonodular and umbilicated skin lesions, some with ulceration and central necrosis resembling molluscum contagiosum. The overall impression reminded us of talaromycosis: we therefore initiated empirical treatment with amphotericin B, even though the case history of this patient did not support such a diagnosis. On the second day of infusion, the patient complained of intermittent headache, but the brain CT revealed no abnormalities. On the third day, a lumbar puncture was performed. The cerebral spinal fluid (CSF) was turbid, with slightly increased pressure. India ink staining was positive, but the cryptococcus antigen latex agglutination test (CrAgLAT: IMMY, USA) was negative. Two days later, the blood culture showed a growth of Cryptococcus neoformans, and the same result came from the skin culture. We added fluconazole to the patient's treatment, but unfortunately, he died three days later. Case two was a sixty-four-year-old female patient with mild fever, productive cough, dyspnea upon movement, and swelling in both lower limbs. The patient was empirically put on cotrimoxazole per os and moxifloxacin by infusion. A bronchofibroscopy was conducted with a fungal culture, showing growth of Cryptococcus laurentii colonies. Amphotericin B was started thereafter but discontinued three days later in favor of fluconazole 400 mg/d due to worsening renal function. The patient became afebrile after 72 h of treatment with considerable improvement of other comorbidities and was finally discharged with continuing oral antifungal therapy.. Our cases illustrate that cryptococcal disease is an important consideration when treating immunocompromised individuals such as AIDS patients. Life threatening meningitis or meningoencephalitis caused by C. neoformansmay still common in these populations and can vary greatly in clinical presentations, especially with regard to skin lesions. Pulmonary cryptococcosis caused by C. laurentii is rare, but should also be considered in certain contexts. Guidelines for its earlier diagnosis, treatment and prophylaxis are needed.

Trichosporonosis in Pediatric Patients With a Hematologic Disorder.
Trichosporonosis is an emerging and often fatal opportunistic fungal infection in immunocompromised patients, particularly those with hematologic malignancy, but data in children are lacking.. We report here 3 cases of invasive infection caused by Trichosporon asahii in pediatric patients with acute lymphoblastic leukemia at Texas Children's Hospital in Houston, Texas. We also conducted a literature review and identified 16 additional reports of pediatric patients with invasive T asahii infection and an underlying malignant or nonmalignant hematologic disorder.. Of the 19 cases of invasive T asahii infection, the most commonly reported underlying hematologic disorder was acute lymphoblastic leukenia (47%), followed by acute myelogenous leukemia (21%). Most of the patients (94%) had neutropenia, defined as an absolute neutrophil count of <500 cells/mm3. Antifungal prophylaxis information was available in 6 of the 19 cases, and micafungin use was reported in 5 cases. Treatment regimens frequently included voriconazole monotherapy (47%) or the combination of an azole antifungal with amphotericin B (35%). The mortality rate was 58%.. Recognizing that echinocandins, which are increasingly used for prophylaxis in patients with a hematologic malignancy, are not active against Trichosporon species is of critical importance. The recommended first-line therapy for trichosporonosis is voriconazole, but successful outcome depends largely on the underlying immune status of the host.

Primary cutaneous aspergillosis caused by Aspergillus tamarii in a premature infant with extremely low birthweight: A case report with short review.
Primary cutaneous aspergillosis is a rare, life-threatening fungal infection in premature infants. We report a case of primary cutaneous aspergillosis caused by Aspergillus tamarii in an extremely low birthweight infant. The infant was delivered by cesarean section with complications from an intrauterine infection, brain intraventricular hemorrhage, tension pneumothorax and cardiac tamponade. On the 12th day of life, he developed erythematous maceration with erosion on his back. Septate hyphae were detected on two occasions from specimens of the skin lesion. The manifestations of the colony and slide culture showed the characteristics of A. tamarii. The nucleotide sequences of internal transcribed spacer regions of the ribosomal RNA gene, partial sequences of β-tubulin and calmodulin gene were compatible with those of A. tamarii. Of the known Aspergillus species, Aspergillus fumigatus and Aspergillus flavus have been reported in previous studies as the major causative agents in primary cutaneous aspergillosis, whereas human infection by A. tamarii is rare. We consider that A. tamarii is important as an unusual opportunistic human pathogen among premature infants.

Visceral leishmaniasis in hematopoietic cell transplantation: Case report and review of the literature.
Visceral leishmaniasis has been recognized as an opportunistic infection affecting people with cellular-immunity impairment, including hematopoietic cell transplantation (HCT) recipients. We describe the case of a young Italian man with Hodgkin lymphoma, who developed visceral leishmaniasis after multiple lines of chemotherapy and allogenic HCT. Literature review of visceral leishmaniasis in HCT recipients was also performed. Eleven patients (median age 50 years, 9 male) developed visceral leishmaniasis after allogenic (n = 9) and autologous (n = 2) HCT. Most of them presented with fever and pancytopenia. Bone marrow examination was the main diagnostic technique; liposomal amphotericin B was the treatment of choice. Four out of eight patients (for whom data are available) experienced visceral leishmaniasis relapse. Visceral leishmaniasis in HCT recipients is a rare event that should be suspected in patients with persistent fever, pancytopenia and possible exposure to Leishmania spp., remembering that - as well as South-East Asia, East Africa and South America - it is endemic in several European regions.

Phylogenetic analysis reveals two genotypes of the emerging fungus Mucor indicus, an opportunistic human pathogen in immunocompromised patients.
Mucormycosis is a rare fungal infection caused by Mucor indicus. Phylogenetic analysis of many M. indicus isolates, mainly sampled from different clinical and environmental specimens collected worldwide, revealed two genotypes, I and II, based on ITS and D1/D2 LSU rDNA sequences. A retrospective review of the literature revealed 13 cases. Eight (76.9%) patients had disseminated infections, and the overall mortality rate was 30.7%. A pulmonary infection caused by M. indicus genotype I in a liver transplant recipient was disseminated to include the skin and was successfully treated with liposomal amphotericin B and aggressive surgery. M. indicus can infect a wide variety of patients with no real preference for the site of infection. We concluded that M. indicus has emerged as a significant cause of invasive mycosis in severely immunocompromised patients worldwide. Early diagnosis and initiation of appropriate therapy could enhance survival in these immunocompromised patient populations.

Presentation and Treatment of Histoplasmosis in Pediatric Oncology Patients: Case Series and Review of the Literature.
Histoplasmosis is an endemic fungus in several regions of the United States. The diagnosis and treatment of this infection can be challenging in pediatric oncology patients. We present 5 patients diagnosed with histoplasmosis while receiving treatment at a midsize pediatric oncology center in Iowa. Two cases occurred in patients with acute lymphoblastic leukemia and 3 cases in patients with solid tumors. All patients were treated with antifungal therapy and demonstrated excellent clinical response. Histoplasmosis should be considered as a potential cause of nonspecific febrile illness, pulmonary masses, and bone marrow suppression in immunocompromised patients in endemic regions. Prompt and accurate diagnosis can facilitate timely antifungal therapy and avoidance of prolonged hospital stays, invasive testing, unnecessary antibiotics, and unwarranted anticancer therapies.

Pseudozyma and other non-Candida opportunistic yeast bloodstream infections in a large stem cell transplant center.
Non-Candida opportunistic yeasts are emerging causes of bloodstream infection (BSI) in immunocompromised hosts. However, their clinical presentation, management, and outcomes in stem cell transplant (SCT) recipients are not well described. We report the first case to our knowledge of Pseudozyma BSI in a SCT recipient. He had evidence of cutaneous involvement, which has not been previously described in the literature. He became infected while neutropenic and receiving empiric micafungin, which is notable because Pseudozyma is reported to be resistant to echinocandins. He was successfully treated with the sequential use of liposomal amphotericin B and voriconazole. A review of the literature revealed nine reported instances of Pseudozyma fungemia. We performed a retrospective review of 3557 SCT recipients at our institution from January 2000 to June 2015 and identified four additional cases of non-Candida yeast BSIs. These include two with Cryptococcus, one with Trichosporon, and one with Saccharomyces. Pseudozyma and other non-Candida yeasts are emerging pathogens that can cause severe and disseminated infections in SCT recipients and other immunocompromised hosts. Clinicians should have a high degree of suspicion for echinocandin-resistant yeasts, if patients develop breakthrough yeast BSIs while receiving echinocandin therapy.

Cryptococcus neoformans infection in malignancy.
Cryptococcosis is an opportunistic invasive fungal infection that is well described and easily recognised when it occurs as meningitis in HIV-infected persons. Malignancy and its treatment may also confer a higher risk of infection with Cryptococcus neoformans, but this association has not been as well described. A case of cryptococcosis in a cancer patient is presented, and all cases of coincident C. neoformans infection and malignancy in adults published in the literature in English between 1970 and 2014 are reviewed. Data from these cases were aggregated in order to describe the demographics, type of malignancy, site of infection, clinical manifestations, treatment and outcomes of cryptococcosis in patients with cancer. Haematologic malignancies accounted for 82% of cases, with lymphomas over-represented compared to US population data (66% vs. 53% respectively). Cryptococcosis was reported rarely in patients with solid tumours. Haematologic malignancy patients were more likely to have central nervous system (P < 0.001) or disseminated disease (P < 0.001), receive Amphotericin B as part of initial therapy (P = 0.023), and had higher reported mortality rates than those with solid tumours (P = 0.222). Providers should have heightened awareness of the possibility of cryptococcosis in patients with haematologic malignancy presenting with infection.

Treatment of mucormycosis in transplant patients: role of surgery and of old and new antifungal agents.
Mucormycosis is an opportunistic mold infection whose management is difficult, as there is a paucity of evidence-based data. We summarize the latest advances in diagnosis and management of mucormycosis in transplant recipients.. There is promise for improvement in nonculture-based diagnostics with new biomarkers of Mucorales DNA that can be used for early diagnosis, and monitoring of response. Antifungal treatment consists of high-dose lipid formulations of amphotericin B or isavuconazole as the first-line therapy and posaconazole as salvage therapy. The new, pharmacokinetically more reliable formulations of posaconazole (intravenous, extended-release tablets) are welcomed improvements. Yet, the role of combination therapy is still uncertain. Surgery had a significant role in selected cases, such as in patients with rhinosinusitis form of mucormycosis, which nowadays can be performed with minimal invasive technique.. Mucormycosis remain a life-threatening opportunistic mold infection among transplant patients. Early diagnosis, prompt treatment with effective antifungals in combination with surgery if feasible is essential. Immune adjunct therapy and improvement of early diagnostics are important areas for future research. There are good prospects of progress in diagnostics and management of mucormycosis in transplant patients.

A Case of Cutaneous Fusariosis of the Scrotum as a Complication of Acute Myeloid Leukemia.
Fusarium, a hyphomyocetous fungus, is often isolated from the environment as a laboratory contaminant, but is also known as a pathogen causing keratomycosis, onychomycosis, and opportunistic infection of the skin and viscera. We report a 67-year-old man with localized cutaneous fusariosis of the scrotum, as a complication of acute myeloid leukemia (AML) under chemotherapy. An induration of 25 mm in diameter, which was covered by necrosis and black crust and with pain upon pressure, was found on the scrotum. Direct microscopic examination of the necrosis showed numerous fungal elements. Culture on Sabouraud dextrose agar with cycloheximide yielded a floccose, grayish white colony. Microscopically, crescent-shaped macroconidia and oval microconidia were abundant. The fungus was identified using gene analysis as Fusarium falciforme of the Fusarium solani species complex. The lesion was treated by voriconazole (total dose: 66,180 mg) and was reduced to 15 mm in diameter. Other metastatic lesions did not appear. After 4 months from the first visit to our department, the patient died of AML. It is believed that the treatment in the early stage of infection prevented further extension of the lesion. During examination of necrotic lesions occurring on the skin of patients with hematological malignancies, it is important to include mycological examination for opportunistic fungal infections, such as aspergillosis or fusariosis, which are easily overlooked by routine culture methods using conventional media with cycloheximide. This paper summarizes cases of cutaneous fusariosis in Japan.

Invasive Aspergillosis in Hematological Patients.
Invasive aspergillosis (IA) is still one of the leading causes of morbidity and mortality in hematological patients, although its outcome has been improving. Prolonged and profound neutropenia in patients receiving intensive chemotherapy for acute leukemia and stem cell transplantation is a major risk factor for IA. Allogeneic stem cell transplant recipients with graft-versus-host disease and corticosteroid use are also at high risk. Management in a protective environment with high efficiency particular air (HEPA) filter is generally recommended to prevent aspergillosis in patients with prolonged and profound neutropenia. Antifungal prophylaxis against Aspergillus species should be considered in patients with past history of aspergillosis or colonization of Aspergillus species, at facilities with high incidence of IA and those without a protective environment. Early diagnosis and prompt antifungal treatment is important to improve outcome. Imaging studies such as computed tomography and biomarkers such as galactomannan antigen and β-D-glucan are useful for early diagnosis. Empirical antifungal treatment based on persistent or recurrent fever during neutropenia despite broad-spectrum antibiotic therapy is generally recommended in high-risk patients. Alternatively, a preemptive treatment strategy has recently been proposed in the context of progress in the early diagnosis of IA based on the results of imaging studies and biomarkers. Voriconazole is recommended for initial therapy for IA. Liposomal amphotericin B is considered as alternative initial therapy. Combination antifungal therapy of echinocandin with voriconazole or liposomal amphotericin B could be a choice for refractory cases.

Alternaria arborescens infection in a healthy individual and literature review of cutaneous alternariosis.
A 28-year-old man presented at our clinic with 1-month history of an ulcer covered with crust on his left anterior tibia. Based on the morphological features and molecular identification, the patient was diagnosed as cutaneous alternariosis caused by Alternaria arborescens. He was successfully cured by oral itraconazole and topical use of 0.25% liposomal amphotericin B. A review of published studies revealed 29 cases of cutaneous alternariosis. Most cases (90%) occurred in immunosuppressed patients; itraconazole (59%) and voriconazole (24%) are the most effective treatments of choices.

[Renal candidal bezoar: case report and review of the literature].
Candida infection is a relatively common hematogenous nosocomial infection in immunocompromised patients. However, renal disease remains unusual. The mode of presentation in the case reported herein was lumbar pain with fever and hydronephrosis of the left kidney due to a fungal bezoar in the renal pelvis. Clinical and biological suspicion of this disease must quickly lead to ultrasound examination to confirm the diagnosis.

Voriconazole versus amphotericin B or fluconazole in cancer patients with neutropenia.
Opportunistic fungal infections are a major cause of morbidity and mortality in neutropenic cancer patients and antifungal therapy is used both empirically and therapeutically in these patients.. To compare the benefits and harms of voriconazole with those of amphotericin B and fluconazole when used for prevention or treatment of invasive fungal infections in cancer patients with neutropenia.. Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2014, Issue 1 2014), MEDLINE (to January 2014). Letters, abstracts and unpublished trials were accepted. Contact was made with trial authors and industry.. Randomised clinical trials comparing voriconazole with amphotericin B or fluconazole.. Data on mortality, invasive fungal infection, colonisation, use of additional (escape) antifungal therapy and adverse effects leading to discontinuation of therapy were extracted independently by two review authors.. Three trials were included. One trial compared voriconazole to liposomal amphotericin B as empirical treatment of fever of unknown origin (suspected fungal infection) in neutropenic cancer patients (849 patients, 58 deaths). The second trial compared voriconazole to amphotericin B deoxycholate in the treatment of confirmed and presumed invasive Aspergillus infections (391 patients, 98 deaths). The third trial compared fluconazole to voriconazole for prophylaxis of fungal infections in patients receiving allogeneic stem cell transplantation (600 patients, number of deaths not stated). In the first trial, voriconazole was significantly inferior to liposomal amphotericin B according to the trial authors' prespecified criteria. More patients died in the voriconazole group and a claimed significant reduction in the number of breakthrough fungal infections disappeared when patients arbitrarily excluded from the analysis by the trial authors were included. In the second trial, the deoxycholate preparation of amphotericin B was used without any indication of the use of premedication to counter side effects and replacement of electrolytes or use of salt water. This choice of comparator resulted in a marked difference in the duration of treatment on the trial drugs (77 days with voriconazole versus 10 days with amphotericin B) and precluded meaningful comparisons of the benefits and harms of the two drugs. The third trial failed to find a difference in fungal free survival or invasive fungal infections at 180 days when voriconazole was compared to fluconazole.. Liposomal amphotericin B is significantly more effective than voriconazole for empirical therapy of fungal infections in neutropenic cancer patients and should be preferred. For treatment of aspergillosis, there are no trials that have compared voriconazole with amphotericin B given under optimal conditions. For prophylactic fungal treatment in patients receiving allogeneic stem cell transplantation, there was no difference between voriconazole and fluconazole regarding fungal free survival or invasive fungal infections.

Nystatin prophylaxis and treatment in severely immunodepressed patients.
Nystatin is sometimes used prophylactically in patients with severe immunodeficiency or in the treatment of fungal infection in such patients, although its effect seems to be equivocal.. To study whether nystatin decreases morbidity and mortality when given prophylactically or therapeutically to patients with severe immunodeficiency.. We searched PubMed from 1966 to 7 July 2014 and the reference lists of identified articles.. Randomised clinical trials comparing nystatin with placebo, an untreated control group, fluconazole or amphotericin B.. Data on mortality, invasive fungal infection and colonisation were independently extracted by both authors. A random-effects model was used unless the P value was greater than 0.10 for the test of heterogeneity.. We included 14 trials (1569 patients). The drugs were given prophylactically in 12 trials and as treatment in two. Eleven trials were in acute leukaemia, solid cancer, or bone marrow recipients; one in liver transplant patients; one in critically ill surgical and trauma patients; and one in AIDS patients. Nystatin was compared with placebo in three trials, with fluconazole in 10, and amphotericin B in one; the dose varied from 0.8 MIE to 72 MIE daily and was 2 mg/kg/d in a liposomal formulation. The effect of nystatin was similar to that of placebo on fungal colonisation (relative risk (RR) 0.85, 95% confidence interval (CI) 0.65 to 1.13). There was no statistically significant difference between fluconazole and nystatin on mortality (RR 0.75, 95% CI 0.54 to 1.03) whereas fluconazole was more effective in preventing invasive fungal infection (RR 0.40, 95% CI 0.17 to 0.93) and colonisation (RR 0.50, 95% CI 0.36 to 0.68). There were no proven fungal infections in a small trial that compared amphotericin B with liposomal nystatin. The results were very similar if the three studies that were not performed in cancer patients were excluded. For the 2011 and 2014 updates no additional trials were identified for inclusion.. Nystatin cannot be recommended for prophylaxis or the treatment of Candida infections in immunodepressed patients.

Cutaneous protothecosis in patient with diabetes mellitus and review of published case reports.
Protothecosis is an opportunistic infection caused by Prototheca, usually called as saprophytes, and is frequently found in natural and living surroundings with low virulence, but may cause chronic infection in immunocompromised individuals. We report a case of cutaneous protothecosis with zopfii var. portoricensis infection in a 66-year-old diabetic woman following hand surgery on middle right finger. Mycology study showed that smooth, creamy white, yeast-like colonies grown after necrotic tissue was cultured on Sabouraud dextrose agar at both 37 and 25°C. The organism was then identified as Prototheca zopfii var. portoricensis by molecular identification and also found from histopathology of the lesion. The lesion got improved with intravenous amphotericin B and itraconazole.

Invasive mycoses: diagnostic challenges.
Despite the availability of newer antifungal drugs, outcomes for patients with invasive fungal infections (IFIs) continue to be poor, in large part due to delayed diagnosis and initiation of appropriate antifungal therapy. Standard histopathologic diagnostic techniques are often untenable in at-risk patients, and culture-based diagnostics typically are too insensitive or nonspecific, or provide results after too long a delay for optimal IFI management. Newer surrogate markers of IFIs with improved sensitivity and specificity are needed to enable earlier diagnosis and, ideally, to provide prognostic information and/or permit therapeutic monitoring. Surrogate assays should also be accessible and easy to implement in the hospital. Several nonculture-based assays of newer surrogates are making their way into the medical setting or are currently under investigation. These new or up-and-coming surrogates include antigens/antibodies (mannan and antimannan antibodies) or fungal metabolites (d-arabinitol) for detection of invasive candidiasis, the Aspergillus cell wall component galactomannan used to detect invasive aspergillosis, or the fungal cell wall component and panfungal marker β-glucan. In addition, progress continues with use of polymerase chain reaction- or other nucleic acid- or molecular-based assays for diagnosis of either specific or generic IFIs, although the various methods must be better standardized before any of these approaches can be more fully implemented into the medical setting. Investigators are also beginning to explore the possibility of combining newer surrogate markers with each other or with more standard diagnostic approaches to improve sensitivity, specificity, and capacity for earlier diagnosis, at a time when fungal burden is still relatively low and more responsive to antifungal therapy.

Safety and interactions of new antifungals in stem cell transplant recipients.
Invasive fungal diseases (IFDs) are a major cause of morbidity and mortality in patients undergoing allogeneic hematopoietic stem cell transplant (HSCT). Considerable progress in treating IFDs has been achieved over the last years, through the availability of new, effective drugs. However, many of these newer antifungal agents have some limitations, such as their variable toxicity and unique predisposition for pharmacokinetic drug-drug interactions.. This article reviews the literature evaluating the safety profile of the lipid formulations of Amphotericin B, echinocandins, and second-generation triazoles. It also discusses the possible drug-drug interactions with some drugs commonly used in allogeneic HSCT.. Nephrotoxicity is the most frequent side effect of lipid formulations of Amphotericin B, which may cause a reduced clearance of the renally eliminated calcineurin inhibitors used for the control of Graft Versus Host Disease. Second-generation triazoles are characterized by a limited toxicity profile, but also by frequent drug-drug interactions with other drugs metabolized by the hepatic enzymes. The echinocandins are characterized by a very low toxicity profile and negligible interactions with other drugs. Such pharmacological knowledge is crucial in the daily care of allogeneic HSCT patients.

Disseminated Penicillium marneffei infection in an SLE patient: a case report and literature review.
Penicillium marneffei is an important opportunistic pathogen in Southeast Asia in HIV-positive individuals, but it rarely infects non-HIV ones. Four SLE patients with disseminated penicilliosis had been previously reported out of which 3 died. We describe a 46-year-old Chinese woman who had a 10 years history of SLE, associated with disseminated Penicillium marneffei infection, which presented as fever, subcutaneous masses, and fine nodular shadows disseminated over lung fields. She was initially misdiagnosed as miliary tuberculosis and panniculitis that did not respond to anti-tubercular drugs and prednisone. The correct diagnosis was finally made by histopathology and tissue culture and also culture from exudate. She responded well to antifungal therapy in the form of intravenous amphotericin B for 2 weeks followed by itraconazole plus fluconazole. The cutaneous lesions were cured leaving behind scars by secondary suture after times of epluchage, and the fine nodular shadows over lungs disappeared finally. She had no recurrence on 8 months of follow-up. We also review the literature on this topic.

Rhodotorula fungemia: two cases and a brief review.
Rhodotorula is emerging as an important cause of nosocomial and opportunistic infections. We present two cases of Rhodotorula mucilaginosa fungemia diagnosed over a period of 3 months at our hospital. The first case was of a pre-term neonate in the neonatal ICU who presented with respiratory failure and sepsis. The second involved an adult female who had been injured in a road traffic accident requiring an operation for a hematoma and was later shifted to the medical ICU. For a new hospital like ours, finding two cases of Rhodotorula fungemia within a span of 3 months prompted us to describe them in this report. These cases emphasize the emerging importance of Rhodotorula mucilaginosa as a pathogen and the importance of identification and MIC testing for all fungal isolates recovered from the blood stream.

Pulmonary aspergillosis: recent advances.
Aspergillosis remains a significant cause of morbidity and mortality. The spectrum of disease is diverse and ranges from noninvasive disease with an excessive immune response, such as in allergic bronchopulmonary aspergillosis (ABPA), to a lack of an immune response as seen in patients with quantitative or qualitative granulocyte deficits and subsequent invasive pulmonary aspergillosis. Noninvasive diagnostic testing has improved the time to initiation of effective antifungal therapy, and numerous agents in different therapeutic classes are now available as treatment options. Voriconazole remains the preferred agent in the treatment of invasive pulmonary aspergillosis, and recent data have increased interest in the potential of combination therapy against this often lethal infection. The role of host genetics in selecting patients that may benefit from more aggressive antifungal prophylaxis or treatment practices remains unclear but is likely to guide therapeutic choices as newer data become available.

Spondylodiscitis due to an emergent fungal pathogen: Blastoschizomyces capitatus, a case report and review of the literature.
The study includes a case report and a literature review. The main objective of this study is to present a case of spondylodiscitis due to a fungal pathogen, Blastoschizomyces capitatus and to review the published literature on this emergent fungus in etiology of spondylodiscitis, and osteomyelitis. Osteoarticular involvement due to B. capitatus has been reported in six cases, and vertebral involvement has been seen in five of them. All of these cases had underlying malignancy. Infection is usually advanced at presentation. Case notes and online databases were reviewed. Organism was isolated from bone material in all of the cases and antibiotic treatment by antifungal agents cured the infection. We present another case of infectious spondylodiscitis due to B. capitaus, which is reported first in Turkey and tried to attract attendance to this emergent fungal pathogen as an etiologic agent of spine infections in cancer patients.

Rhino-orbito-cerebral mucormycosis: report of two cases and review of the literature.
Rhino-orbito-cerebral mucormycosis (ROCM) is a rare, fulminant opportunistic fungal infection that is mostly seen in immunocompromised or diabetic patients. The disease should be recognised and treated immediately. We present here MR imaging findings of two patients with histopathologically proven ROCM. One of the cases had a history of corticosteroid treatment and iatrogenic diabetes mellitus and although amphotericin B was started immediately, the disease progressed and surgical debridement was necessary. The second case was a patient with diabetes mellitus type 1 in whom ROCM had occurred following an abdominal surgery; amphotericin B treatment alone was adequate in this patient.

A case of Cunninghamella bertholettiae rhino-cerebral infection in a leukaemic patient and review of recent published studies.
Cunninghamella bertholletiae infection occurs most frequently in neutropenic patients affected by haematological malignancies, is associated with an unfavourable outcome. We report a case of rhino-mastoidal fungal infection in a leukaemic patient. Bioptical tissue cultures yield the isolation of a mould with typical properties of Cunninghamella species. Liposomal amphotericin B (L-Amb) therapy combined with surgical intervention brought the lesion to recovery. Nevertheless, the patient died 14 days after bone marrow transplantation (BMT) from bacterial sepsis. Mastoiditis was documented at CT-scan. The conditioning regimen probably caused the reactivation of the Cunninghamella infection that led to the patient's fatal outcome; fungal hyphae were detected after autopsy of brain and lung tissue.

[Current indications for voriconazole in onco-hematological patients].
Invasive fungal infections (IFI) are the main cause of infectious death in cancer patients, especially in hematological malignancies and hematopoietic transplant recipients. Current epidemiology is characterized by a predominance of IFI caused by molds, mainly aspergillosis, along with a emergence of hard-to-treat fungi such are Zygomicetes, Fusarium and Scedosporium. Voriconazole is a broad spectrum antifungal agent with oral and intravenous formulations, approved by the EMEA for the treatment of invasive aspergillosis, candidemia in non-neutropenic patients, IFI caused by fluconazole-resistant species of Candida as well as Scedosporium and Fusarium infections. However, its use in clinical practice is broader, as empirical antifungal treatment and as secondary prophylaxis. It should be kept in mind the possibility of breakthrough IFI, particularly zygomycosis, in patients treated with voriconazole for long periods.

Voriconazole versus amphotericin B in cancer patients with neutropenia.
Opportunistic fungal infections are a major cause of morbidity and mortality in neutropenic cancer patients and antifungal therapy are used both empirically and therapeutically in these patients.. To compare the benefits and harms of voriconazole with those of amphotericin B and fluconazole when used for prevention or treatment of invasive fungal infections in cancer patients with neutropenia.. MEDLINE and the Cochrane Library (May 2005). Letters, abstracts and unpublished trials were accepted. Contact to authors and industry.. Randomised trials comparing voriconazole with amphotericin B or fluconazole.. Data on mortality, invasive fungal infection, colonisation, use of additional (escape) antifungal therapy and adverse effects leading to discontinuation of therapy were extracted by two authors independently.. Two trials were included. One trial compared voriconazole to liposomal amphotericin B as empirical treatment of fever of unknown origin (suspected fungal infections) in neutropenic cancer patients (849 patients, 58 deaths). The other trial compared voriconazole to amphotericin B deoxycholate in the treatment of confirmed and presumed invasive Aspergillus infections (391 patients, 98 deaths). In the first trial, voriconazole was significantly inferior to liposomal amphotericin B according to the authors' prespecified criteria. More patients died in the voriconazole group and a claimed significant reduction in the number of breakthrough fungal infections disappeared when patients arbitrarily excluded from analysis by the authors were included. In the second trial, the deoxycholate preparation of amphotericin B was used without any indication of the use of premedication and substitution with electrolytes and salt water to avoid handicapping this drug. This choice of comparator resulted in a marked difference in the duration of treatment on trial drugs (77 days with voriconazole versus 10 days with amphotericin B), and precludes meaningful comparisons of the benefits and harms of the two drugs.. Liposomal amphotericin B is significantly more effective than voriconazole for empirical therapy of neutropenic cancer patients and should be preferred. For treatment of aspergillosis, there are no trials that have compared voriconazole with amphotericin B given under optimal conditions.

Central venous catheter-related infection due to Candida membranaefaciens, a new opportunistic azole-resistant yeast in a cancer patient: a case report and a review of literature.
An unusual central venous catheter (CVC)-related infection caused by Candida membranaefaciens in a patient with non-Hodgkin's lymphoma is described. Clinical signs and microbiological results observed in this case may support the hypothesis of an emerging CVC-related fungaemia, because of new azole-resistant yeast, successfully treated with liposomal amphotericin B. To date C. membranaefaciens (the teleomorph of Pichia membranaefaciens) has traditionally been considered non-pathogenic and this report seems to be the first case of systemic fungal infection. We believe that another fungus can be added to the list of opportunistic strains.

Empirical antifungal therapy in treating febrile neutropenic patients.
Persistent or recurrent unexplained fever in neutropenic patients receiving antibiotics can be caused by invasive fungal infections, which are often difficult to diagnose. Early trials of empirical antifungal therapy with amphotericin B deoxycholate (AmB) documented reductions in the frequency of and the morbidity and mortality associated with invasive fungal infections. Because of AmB's infusional and renal toxicities, subsequent trials used newer, less toxic agents, such as the lipid formulations of AmB, the extended-spectrum azoles, and, more recently, the echinocandins. To date, alternatives to AmB have shown less toxicity, but improved efficacy has been less clear. Overall, empirical antifungal therapy can help prevent the morbidity associated with many fungal infections, eliminate concerns about diagnostic pitfalls, and prevent breakthrough undetected infections. However, its potential shortcomings are overtreatment, toxicity, and increased treatment-related costs when treatment is given to persons not needing it. Newer diagnostic tools are needed to target those most in need of antifungal therapy.

Improved outcome of zygomycosis in patients with hematological diseases?
Zygomycosis is an opportunistic fungal infection that is increasingly reported in hematological patients. We describe 2 cases of successfully treated rhino-cerebral zygomycosis and give an overview of 120 patients from the literature with underlying hematological or oncological disorders. These data document the improved survival in sinus (15/17 patients surviving) and cutaneous (6/9 patients surviving) disease. Hematological patients with pulmonary (9/30 patients surviving) or disseminated (4/38 patients surviving) zygomycosis still have a poor prognosis. The clinical course of sinus-orbital involvement (4/11 patients surviving) follows sinus-cerebral (2/3 patients surviving) or cerebral (3/6 patients surviving) disease. Besides deoxycholate amphotericin B (AmB) (24/62 patients surviving), patients seem to benefit from liposomal amphotericin B (L-AmB) (10/16 patients surviving) or sequential AmB/L-AmB treatment (6/8 patients surviving). Alternative treatment options lead only in a few patients to success.

Aspergillus endocarditis in a native valve after amphotericin B treatment.
Systemic infection with Aspergillus fumigatus is an opportunistic disease that affects mainly immunocompromised hosts and is associated with a high mortality rate. We report a case of A. fumigatus endocarditis after an episode of thrombotic thrombocytopenic purpura. Diagnosis was established after sudden rupture of posterior papillary muscle of the normal native mitral valve. Soon after mitral valve replacement, Aspergillus endocarditis recurred, associated with multiple peripheral emboli, which necessitated a second operation.

Nystatin prophylaxis and treatment in severely immunodepressed patients.
Nystatin is sometimes used prophylactically in patients with severe immunodeficiency or in the treatment of fungal infection in such patients, although the effect seems to be equivocal.. To study whether nystatin decreases morbidity and mortality when given prophylactically or therapeutically to patients with severe immunodeficiency.. MEDLINE and The Cochrane Library using a comprehensive search strategy, date of last search November 2001. Contacted industry and scanned reference lists.. Randomised trials comparing nystatin with placebo, an untreated control group, fluconazole or amphotericin B.. Data on mortality, invasive fungal infection and colonisation were extracted by both authors independently. A random effects model was used unless p>0.10 for the test of heterogeneity.. We included 12 trials (1,464 patients). The drugs were given prophylactically in ten trials and as treatment in two. Seven trials were in acute leukaemia, two in cancer, one in liver transplant patients, one in critically ill surgical and trauma patients, and one in AIDS patients. Nystatin had been compared with placebo in three trials and with fluconazole in nine; the dose varied from 1.5 MIE to 72 MIE daily. The effect of nystatin was similar to that of placebo on fungal colonisation (relative risk 0.85, 95% confidence interval 0.65 to 1.13). There was no statistically significant difference between fluconazole and nystatin on mortality (relative risk 0.76, 0.49 to 1.18) whereas fluconazole was more effective in preventing invasive fungal infection (relative risk 0.37, 0.15 to 0.91) and colonisation (relative risk 0.49, 0.34 to 0.70). The results were very similar if the three studies which were not performed in cancer patients were excluded..

Two cases of fungemia due to Candida lusitaniae and a literature review.
Reported here are two cases of candidemia caused by Candida lusitaniae that occurred in two immunocompromised patients at Hospital Universitario "La Fe" in Valencia, Spain. Case 1 involved a low-birth-weight premature infant with congenital nephrotic syndrome who was successfully treated with amphotericin B, and case 2 involved a 50-year old woman with a high-grade malignancy lymphoma who succumbed to the infection. Antifungal susceptibility testing of the Candida lusitaniae isolates recovered from both patients revealed sensitivity to amphotericin, 5-flucytosine and fluconazole. Results are presented and discussed together with a comprehensive review of the literature, covering all previously reported cases of fungemia caused by this emerging pathogen.

Treatment of systemic fungal infections in older patients: achieving optimal outcomes.
Systemic fungal infections are an increasing problem in older adults. For several of the endemic mycoses, this increase is the result of increased travel and leisure activities in areas endemic for these fungi. Immunosuppressive agents, care in an intensive care unit, and invasive devices all contribute to infection with opportunistic fungi. Treatment of systemic fungal infections is usually with an azole or amphotericin B. The preferred regimen depends on the specific fungal infection, the site and the severity of the infection, the state of immunosuppression of the patient and the possible toxicities of each drug for a specific patient. In older adults, drug-drug interactions between the azoles and drugs commonly prescribed for older persons may lead to serious toxicity, and absorption of itraconazole can be problematic. Amphotericin B is associated with significant nephrotoxicity, especially in older adults with pre-existing renal disease, and infusion-related adverse effects. Newer lipid formulations of amphotericin B can obviate some of these toxicities, but their role in the treatment of systemic fungal infections in older adults has not yet been clarified.

Liposomal amphotericin B (AmBisome) for fungal infections in immunocompromised adults and children.
Invasive fungal infections are rare but life-threatening infections, most often occurring in immunocompromised patients. For a long time, Amphotericin B has been the best choice for treatment, because it is fungicidal with a broad antifungal spectrum and minimal risk of resistance development. The therapeutic use of amphotericin B has, however, been limited by its toxicity-both acute as well as chronic. To counter this, amphotericin B has been encapsulated in liposomes, which reduces its toxicity and allows higher doses to be given. Ambisome is a true, spherical, small unilamellar liposome with a median size of 80 nm. The pharmacokinetic profile was changed, and the maximum concentration and AUC of amphotericin B after AmBisome treatment were greater than those found with the conventional drug. The highest tissue concentrations of AmBisome were found in the liver and spleen, and less than 1% of the administered dose was recovered in other organs. At Huddinge University Hospital, we were the first to use and report on the experience of AmBisome. We now have more than 12 years' experience in transplant recipients, with a good safety profile, improved rate of curing mycological proven infections and reduced mortality in fungal infections. In two placebo-controlled prophylactic trials, we found that AmBisome was effective for preventing fungal colonization and invasive fungal infections, respectively, in allogeneic stem cell and liver transplantation. In uncontrolled and, more recently, in randomized controlled studies at other centers, AmBisome has revealed less toxicity and an efficacy equal or superior to that of the conventional drug in treating neutropenia-associated fever and proven invasive fungal infections in both adults as well as in children. Although investigators tend to increase the dose used, the optimal dose for probable or proven infection is still under debate. Based on our own experience in using AmBisome and the experience at other centers, we can conclude that AmBisome represents a major breakthrough in the treatment of invasive fungal infections, especially in immunocompromised patients.

Antifungal prophylaxis in hematopoietic stem cell transplant recipients.
Efforts at preventing and treating fungal infection in hematopoietic stem cell transplant (HSCT) recipients must take into account the types of infections likely to be encountered during the different risk periods in hosts with different underlying risks. Given the emergence of molds as prevalent pathogens and the long duration of risk in allogeneic HSCT recipients, optimal antifungal prophylaxis would consist of treatment that can be given over a prolonged period and that would provide both anti-Candida and anti-Aspergillus activity. Optimal empiric therapy would consist of a broad-spectrum agent in the absence of more sensitive and specific methods for microbial diagnosis. Fluconazole (Diflucan) is currently the standard prophylactic agent for candidiasis, although mold-active agents and alternative strategies for polyene administration are being investigated. The gold standardfor empiric therapy is currently a polyene antifungal, yet an increased appreciation for amphotericin B-resistant yeasts and molds, and less toxic mold-active alternatives, might lead to the use of other compounds in the future. The recent development of multiple alternatives emphasizes our need to establish treatment algorithms that consider both the likely pathogens and potential toxicities.

Trichosporon beigelii infection: experience in a regional burn center.
Trichosporon beigelii is a fungus once thought to cause only superficial infections, but recently has been increasingly identified as an opportunistic systemic pathogen in immunocompromised patients. There have been very limited reports of this organism in the burn patient population. We describe the first report of pharmacological management of invasive T. beigelii with a combination of amphotericin B and high dose fluconazole in a burn patient.

Oral candidal infections and antimycotics.
The advent of the human immunodeficiency virus infection and the increasing prevalence of compromised individuals in the community due to modern therapeutic advances have resulted in a resurgence of opportunistic infections, including oral candidoses. One form of the latter presents classically as a white lesion of "thrush" and is usually easily diagnosed and cured. Nonetheless, a minority of these lesions appears in new guises such as erythematous candidosis, thereby confounding the unwary clinician and complicating its management. Despite the availability of several effective antimycotics for the treatment of oral candidoses, failure of therapy is not uncommon due to the unique environment of the oral cavity, where the flushing effect of saliva and the cleansing action of the oral musculature tend to reduce the drug concentration to sub-therapeutic levels. This problem has been partly circumvented by the introduction of the triazole agents, which initially appeared to be highly effective. However, an alarming increase of organisms resistant to the triazoles has been reported recently. In this review, an overview of clinical manifestations of oral candidoses and recent advances in antimycotic therapy is given, together with newer concepts, such as the post-antifungal effect (PAFE) and its possible therapeutic implications.

U.S. case report of cerebral phaeohyphomycosis caused by Ramichloridium obovoideum (R. mackenziei): criteria for identification, therapy, and review of other known dematiaceous neurotropic taxa.
We report a case of cerebral phaeohyphomycosis in a 36-year-old male caused by the neurotropic fungus Ramichloridium obovoideum (Matushima) de Hoog 1977 (Ramichloridium mackenziei Campbell et Al-Hedaithy 1993). This man resided in the Middle East, where the fungus appears to be endemic and, possibly, geographically restricted, since all previous reports of brain abscesses due to this organism have been for patients indigenous to this area. As a servant of the Saudi Arabian royal family, he appeared in the United States seeking treatment for chronic weight loss, fatigue, decreased memory, and a more recent 2-week history of right-hand weakness which worsened to involve the entire right upper extremity. On the day prior to his admission, he had a focal motor seizure with rotation of the head and eyes to the right, followed by secondary generalization. A computerized tomogram showed a ring-enhancing hypodense lesion in the left parietal subcortical region with associated edema and mass effect. Diagnosis of a fungal etiology was made following a parietal craniotomy and excisional biopsy by observation of septate, dematiaceous hyphal elements 2 to 3 microm in width on hematoxylin-and-eosin-stained sections from within areas of inflammation and necrosis. Culture of the excised material grew out a dematiaceous mould which was subsequently identified as R. obovoideum. At two months postsurgery and with a regimen of 200 mg of itraconazole twice a day, the patient was doing well and returned to Saudi Arabia. His condition subsequently deteriorated, however, and following a 7-month course of itraconzole, he expired. We use this case to alert clinicians and personnel in clinical mycology laboratories of the pathogenicity of this organism and its potential occurrence in patients with central nervous system signs and symptoms who have resided in the Middle East and to review and/or compare R. obovoideum with other neurotropic, dematiaceous taxa and similar nonneurotropic, dematiaceous species.

Cryptococcosis in Hodgkin's disease: description of two cases and review of the literature.
Systemic mycosis caused by Cryptococcus neoformans frequently becomes life threatening in patients with cellular immunodeficiencies. In contrast to AIDS patients, there are only a few reports of concurrent systemic cryptococcosis in patients with Hodgkin's disease (HD). Only two of 75 (2.7%) patients with HD who were consecutively admitted to our hospital in the past decade developed Cryptococcus neoformans infection. Both had stage IVB (Ann Arbor) HD with bone marrow involvement and absolute lymphopenia (< 1/nl). We have reviewed the literature and analyzed the data of 54 cases with concurrent cryptococcosis and HD. Presence of HD for > or = 12 months, stage IV disease, absolute lymphopenia (< 1/nl), and extensive pretreatment were the most common features among these patients and must be regarded as predisposing for acquiring a cryptococcal infection. In our patients antimycotic therapy was successful using liposomal amphotericin B (lipAmB) simultaneously with cytotoxic therapy for HD. Drug level measurements performed in one patient revealed a higher level of amphotericin B in CSF when the liposomal formulation was administered as compared with the level in CSF after administration of conventional amphotericin B. To our knowledge, this is the first report on antimycotic treatment of cryptococcosis with lipAmB in patients with HD. Regarding the favorable therapeutic index of lipAmB as compared with conventional amphotericin B, the drug should be considered as a less toxic and perhaps more effective alternative in the therapy of acute cryptococcosis, especially when cytotoxic treatment is administered simultaneously.

[Geotrichum capitatum infection in a neutropenic patient. Apropos of a case and review of the literature].
Geotrichum capitatum sepsis are rare, occurring exclusively in immunocompromised patients.. We report the case of a patient with acute leukemia, presenting with chemotherapy-induced neutropenia and hospitalized in an intensive care unit for a severe sepsis. In spite of an antibiotic and antifungal treatment, the patient died of cardiorespiratory failure. Later on, blood cultures proved to be positive for Geotrichum capitatum.. If fungal infections are common in neutropenic patients, Geotrichum capitatum sepsis remain exceptional. The portal of entry is digestive or respiratory, and the invasion is favored by immunodepression and suppression of the normal microbial flora. Induced lesions can be multiorganic. The treatment is not well established, and the association of either amphotericine B and 5-fluorocytosine or amphotericine B and itraconazole would lead to better results. Nevertheless, the prognosis is still unfavorable, with a mortality rate of approximately 75%.

[New aspects in treatment of systemic mycoses].
The incidence of systemic fungal infection has been increasing during the last two decades. Candida and Aspergillus spp. are the classical opportunistic pathogens. Rare fungi, such as Mucor, Rhizopus, Fusarium, Trichosporon, Paecilomyces, Alternaria, Cladosporium and Pseudoallescheria, are emerging as cause of systemic fungal infection in the immunocompromised host. For more than 40 years Amphotericin B has been the gold standard of antifungal treatment because of its broad spectrum comprising yeasts, dimorphic fungi and moulds. Its nephrotoxicity has led to the development of lipid-associated preparations of amphotericin B: liposomal amphotericin B, amphotericin B colloidal dispersion and amphotericin B lipid complex. These preparations are less nephrotoxic, but higher doses than those of conventional amphotericin B are needed to achieve the same effect. The triazole fluconazole is the treatment of choice in infections caused by Candida albicans. New antifungal compounds are voriconazole and the candins, the pradimicin/benanomycin family, nikkomycin Z and a liposomal preparation of nystatin.

New approaches to antifungal chemotherapy.
The antifungal agents currently available to treat invasive fungal infections are limited in both number and usefulness. Treatment with the polyene amphotericin B (AmB), and with several azoles, in particular fluconazole and itraconazole, is the mainstay of antifungal chemotherapy. However, the clinical usefulness of these drugs is hampered by drawbacks associated with their safety and/or efficacy. There are two approaches to overcome this situation. One is to discover and develop new antifungal agents or formulations with advantages over and/or complementary to existing drugs. For this purpose, the following three categories of new drugs have been the major targets of study and development: (i) lipid formulations of polyenes, (ii) azoles (including cyclodextrin-complexes), and (iii) nonazole compounds, particularly those of microbial origin (antibiotics).

Blastomycosis in the immunocompromised patient.
Blastomycosis has become increasingly recognized as a serious infection in immunocompromised hosts in recent years. Underlying disorders among these patients include conditions that are typically characterized by abnormalities of T-lymphocyte function such as acquired immunodeficiency syndrome, long-term glucocorticosteroid use, hematologic malignancy, solid organ transplantation, and pregnancy, in addition to a variety of other diseases. Clinically, the disease in immunocompromised patients is potentially much more severe and is characterized by disseminated multiple organ involvement including frequent involvement of the central nervous system. Adult respiratory distress syndrome and/or miliary pulmonary involvement, relatively rare complications in the normal population, are also common in immunocompromised patients. Most notably, mortality as a result of blastomycosis in these patients exceeds 30% and usually occurs within several weeks of presentation. Because of the severity of the disease, initial therapy with amphotericin B is advised for most immunocompromised patients with blastomycosis to gain control of the disease. The role of itraconazole as initial therapy is probably limited to patients with focal, uncomplicated disease. Many of these patients, particularly those with conditions associated with ongoing immunosuppression, require chronic suppressive therapy with an azole to prevent relapsing disease.

Opportunistic fungal infections: filamentous fungi and cryptococcosis.
Older patients with diabetes mellitus or pulmonary diseases and those receiving immunosuppressive drugs are at an increased risk of infection with environmentally-acquired, opportunistic fungal diseases. Aspergillus most often produces invasive pulmonary or sinus infection in severely immuno-compromised patients. Chronic necrotizing pulmonary and sino-orbital aspergillosis present subacutely and are often misdiagnosed. Mucormycosis classically presents with rhinocerebral disease in diabetic patients with ketoacidosis, whereas pulmonary infection mimics invasive pulmonary aspergillosis and occurs mostly in patients who are neutropenic. Cryptococcal meningitis in the older patient may manifest simply as confusion. Amphotericin B is the preferred initial treatment for all three fungal infections.

[Pulmonary mucormycosis in a leukemia patient. Diagnostic and therapeutic difficulties].
The observation of pulmonary mucormycosis occurring in a patient presenting with aplasia induced therapeutically during treatment for acute myeloblastic leukaemia, has led to a review of the characteristics of this rare opportunistic fungal infection: it occurs in a particular condition; the clinical manifestations are characterised by the thrombotic character and the rapidly necrosing nature of the histological lesions; the diagnosis is usually very difficult to make and is linked to the rarity of the pathology and the frequently negative mycological specimens apart from tissue biopsies; the value of a medicosurgical therapeutic strategy on which the prognosis of the infection depends.

Therapeutic outcome in invasive aspergillosis.
A review of series of > or = 4 cases of invasive aspergillosis (total, 1,223 cases) was undertaken to establish the crude mortality and rate of response to therapy with amphotericin B in the major at-risk host groups. In association with pulmonary, sinus, and cerebral aspergillosis in immunocompromised patients, the crude mortality rates were 86%, 66%, and 99%, respectively. No untreated patient survived. Among 84 patients treated for 1-13 days, only one survived. Among those with invasive pulmonary aspergillosis treated for > or = 14 days, the response rates to amphotericin B deoxycholate were 83% (in cases of heart and renal transplantation), 54% (leukemia), 33% (bone marrow transplantation) and 20% (liver transplantation). Patients with AIDS mostly received both amphotericin B and itraconazole, and 37% of those treated for > or = 14 days responded to therapy. Substantial variation in outcome from series to series was related to underlying disease status, site of disease, and management. Invasive aspergillosis remains a devastating opportunistic infection despite current treatment.

[Empirical antimicrobial therapy in neutropenic patients].
Infectious complications emerge in more than 80% of neutropenic patients after intensive antineoplastic therapy. Empirical antimicrobial intervention is mandatory, and initial administration of an antipseudomonal betalactam in combination with an aminoglycoside represents the most widely applied standard regimen. At least in patients with short-term neutropenia, also an initial betalactam monotherapy is accepted. Symptoms of skin or venous-catheter-related infection should prompt the addition of a glycopeptide, whereas in case of lung infiltrates, amphotericin B should be administered at least after 96 h. of nonresponse to the antibiotic first-line therapy. In nonresponders with persisting fever of unknown origin, carbapenems or fluoroquinolones in combination with a glycopeptide might be considered for second-line treatment. The supplementation of a recombinant hematopoietic growth factor [G-CSF or GM-CSF] shows no significant benefit and should be restricted to controlled clinical studies. In case of good clinical response, the established antimicrobial treatment regimen should be continued for at least seven days in persistently neutropenic patients.

Lethal disseminated Fusarium infection with sinus involvement in the immunocompromised host: case report and review of the literature.
A case of disseminated invasive fusarial infection (DFI) with sinus involvement in a patient with acute myeloblastic leukaemia is reported. Amphotericin B with rifampin were administrated and wide radical sinus surgery was performed. Nevertheless, the patient died six weeks later. The four principal forms of fusarial infections in humans are discussed: toxicosis, allergic fungal sinusitis, locally invasive infection, and disseminated invasive infection. Prognosis of DFI in the immunocompromised host is usually poor, and treatment is difficult. Profound and prolonged neutropaenia appears to be the major predisposing factor. The literature on infections caused by Fusarium species in immunocompromised hosts is reviewed, especially those where the sinuses were involved.

Invasive central nervous system aspergillosis: cure with liposomal amphotericin B, itraconazole, and radical surgery--case report and review of the literature.
Invasive aspergillosis of the central nervous system is a rare but well-described disease. There have been only a few reported survivors, and mortality exceeds 95% in the immunosuppressed host. We present a 2-year-old boy with acute lymphatic leukemia and multiple Aspergillus brain abscesses who was successfully treated with liposomal amphotericin B, itraconazole, and surgical excision of the abscesses. Liposomal amphotericin B is a new preparation that safely allows the attainment of significantly higher tissue levels with less toxicity than standard amphotericin B. The treatment of patients with invasive central nervous system aspergillosis is reviewed.

[Surgical and local treatment in a case of fungal sinusitis in a patient with bone marrow aplasia].
We report a clinical case of severe medullary aplasia complicated by fungal antritis. The treatment adopted for this patient consists in a clean operation of the infective focus and the local instillation of Amfotericina B during the post operative period. In this way the systemic circulation is not interested by the use of Amfotericina B, which is extremely important to avoid the inevitable onset of several unwanted side-effects; besides, we avoid the progression of the infective focus and its systemic diffusion.

[Prophylaxis against mycoses in neutropenic patients].
During the last years, the proportion of cancer patients who develop systemic fungal infections has increased steadily. These infections are characterised by high mortality, especially in patients with persistent granulocytopenia and in those receiving allogeneic bone marrow transplants. The most important pathogens in neutropenic patients are Candida and Aspergillus spp. Usually, Candida infections arise from overgrowth in the gastrointestinal tract, while Aspergillus infections are acquired by inhalation of spores. Prophylaxis of systemic fungal infections seems mandatory since optimal strategies for diagnosis and treatment of these infections are lacking. Treatment with the non-absorbable polyenes nystatin and amphotericin B is useful for prophylaxis of superficial fungal infections, provided that compliance of the patients is optimal. The imidazoles ketoconazole and miconazole can reduce the incidence of superficial fungal infections, but there are conflicting data regarding their value for prevention of systemic mycoses. There are several studies indicating that prophylactic use of fluconazole reduces the incidence of mucosal and systemic fungal infections, especially in patients receiving allogeneic bone marrow transplants. Fluconazole shows reduced activity against several Non-albicans spp. and is not active against Aspergillus spp. Itraconazole has in vitro and in vivo activity against several Aspergillus spp. but high serum and tissue levels are necessary. However, bioavailability of itraconazole is reduced in patients with raised gastric pH and no i.v. formulation is available. Although there is some evidence for its prophylactic activity against Aspergillus infections in neutropenic patients, more studies are necessary to confirm these findings. Intravenous amphotericin B cannot be recommended for routine prophylactic use because of its toxicity.(ABSTRACT TRUNCATED AT 250 WORDS) Topics: Amphotericin B; Antifungal Agents; Aspergillosis; Bone Marrow Transplantation; Candidiasis; Fluconazole; Granulocyte Colony-Stimulating Factor; Humans; Incidence; Itraconazole; Mycoses; Neoplasms; Neutropenia; Opportunistic Infections | 1994 |
[Therapy of systemic candidiasis].
Deep seated candidosis are the most common invasive fungal infections occurring in various categories of patients including those with cancer, burns as well as patients with AIDS or undergoing organ transplantation. Various clinical entities have to be distinguished with implications for diagnostic procedures as well as for adequate therapy. During the last decade, tremendous progress has been achieved leading to a major reduction of mortality attributable for candidaemia from 80% (in the seventies) to 40% in the nineties, mainly due to early empiric antifungal and better prophylaxis treatment. Other antifungal strategies than conventional amphotericin B are now available and have been shown effective, in particular, new modalities to administer amphotericin B including various lipid formulations, but also new azoles and mainly the triazoles such as fluconazole and itraconazole. Fluconazole has been shown effective as prophylaxis of candidosis including in patients undergoing bone marrow transplantation as well as in treatment of oropharyngeal candidosis and for candidaemia occurring in non-neutropenic patients. More limited data are available on itraconazole so far in particular in patients with documented invasive candidosis, but preliminary reports are encouraging. Oral therapy with systemic efficacy is more easy to recommend and allows ambulatory treatment. Candidosis is not a benign disease and in every single patient with fungemia antifungal treatment is mandatory.

Scedosporium inflatum infection in immunocompromised haematological patients.
We report four cases of Scedosporium inflatum (S. inflatum) infection in severely immunocompromised haematological patients. Six well-documented cases of S. inflatum disseminated infection in haematological patients have been reported: four in Australia and two in Spain. Their clinical and pathological characteristics are heterogenous, particularly in the Australian cases. However, the clinical and pathological profile emerging from our and other Spanish cases is homogenous and very similar to the clinico-pathological spectrum of other disseminated mycoses, including Aspergillus and S. apiospermum. The optimal treatment of S. inflatum infection is unknown and the outcome in haematological patients is very poor. Eight patients died despite systemic antifungal treatment.

Treatment of invasive aspergillosis.
Invasive aspergillosis is generally a life-threatening invasive opportunistic mycosis affecting principally the upper and lower respiratory tract. Therapeutic response rates vary considerably from one host group to another with particularly high mortality rates in bone marrow transplant, liver transplant and patients with aplastic anaemia or AIDS. Only two drugs are useful for therapy, amphotericin and itraconazole. Recent advances in the formulation of amphoterin B (AmBisome and Amphocil) have resulted in intravenous preparations with lower toxicity, particularly nephrotoxicity, but it has yet to be shown that they have an increased therapeutic index for the treatment of invasive aspergillosis. Itraconazole can only be used orally and in some particularly high-risk or critically ill patients adequate serum concentrations cannot be achieved. The addition of flucytosine or rifampicin to amphotericin B therapy has, at best, only a marginal benefit. Surgery is essential for some manifestations of invasive aspergillosis. This article reviews therapeutic strategies including criteria for initiation of therapy, combination and sequential therapy, duration of therapy and secondary prophylaxis and indications for surgery in invasive aspergillosis.

[Neurological form of cryptococcosis. Apropos of 2 atypical cases in non HIV-infected patients].
Cryptococcal infection is the most common fungal infection of the central nervous system. More than 50% of the cases of cryptococcal infection are superimposed on an immunosuppressive or other general debilitating condition. Cerebral cryptococcosis usually presents as meningitis or meningoencephalitis, although cerebral granuloma has also been reported. Hydrocephalus is the most common neurosurgical complication of cerebral cryptococcosis. The majority of patients require only medical treatment with antifungal drugs. However, when complications ensue, surgical intervention is mandatory. We suggest that chronic meningitis be ruled out in all patients prior to the placement of shunts. In the two cases reported here treatment of cryptococcal meningitis was a combination of amphotericin B and flucytosine for six weeks. Fluconazole is a new alternative and at least as effective as amphotericin B.

Prevention of invasive fungal infections in patients with neoplastic disease.
Invasive fungal infections are important causes of morbidity and mortality among patients with neoplastic diseases, particularly those with protracted granulocytopenia, those receiving corticosteroids, and those undergoing allogeneic bone marrow transplantation. These mycoses are often difficult to diagnose early, and their treatment is frequently unsuccessful. Antifungal compounds have been used in studies of a variety of preventive strategies including prophylaxis, early empirical therapy, empirical therapy, and secondary prophylaxis. Among all compounds studied thus far, fluconazole has demonstrated the most promising activity in prevention of invasive candidiasis, particularly in adult allogeneic bone marrow transplant recipients. However, fluconazole does not have activity at currently approved dosages against Candida krusei, Torulopsis glabrata, and most filamentous fungi, including Aspergillus species. Empirically administered amphotericin B significantly decreases the frequency of invasive fungal infections in persistently or recurrently febrile granulocytopenic patients. The use of itraconazole for prevention of aspergillosis warrants study. The current lack of reliable preventive regimens against infections due to Aspergillus and against those due to several emerging fungal pathogens presents an ongoing challenge. The use of recombinant human cytokines, transfusion of effector cells, and administration of newer antifungal compounds are new potential modalities for prevention of invasive mycoses.

Coccidioidomycosis and pregnancy.
Pregnant women with respiratory symptoms of pleuritic pain and productive cough should undergo evaluation for coccidioidomycosis. This should include a history of travel or residency in endemic areas and careful assessment for toxic erythema, erythema nodosum, or erythema multiforme. To confirm a diagnosis of this disease, a sputum culture, wet mount, and serological tests should be performed. The risk of dissemination, which is highest in the second and third trimesters, can be estimated by a complement-fixation titer. In disseminated cases aggressive treatment with amphotericin B has improved the previously reported high maternal and neonatal mortality rate. Fortunately, case reports do not indicate that transplacental spread occurs. Reactivation or exacerbation of a chronic low-grade infection during pregnancy may occur in patients treated for prior disseminated disease (32, 34). Interestingly, both of the reported cases of reactivation or exacerbation occurred in insulin-dependent diabetics.

[Choice and monitoring of the treatment of systemic mycoses. Value and limitations of in vitro tests].
Systemic fungal infections are an important cause of morbidity and mortality among immunocompromised patients. New antifungal agents, such as triazoles, are now available, and the place of in vitro tests has to be discussed. It has been shown that interlaboratory reproducibility of in vitro susceptibility tests against fungi was low, due to the lack of standardization. Recently, the NCCLS defined conditions permitting a good interlaboratory reproducibility. However, the predictive value of in vitro susceptibility tests on the therapeutic outcome remain to be demonstrated, and is now under investigation. At the present time, susceptibility testing can be useful: in patients treated by amphotericin B for a severe fungal infection and who do not improve under therapy; to detect resistance to 5-fluorocytosine; to compare the sensitivity to triazoles before and after treatment, in case of therapeutic failure. Serum levels monitoring is useful to prevent the toxicity due to 5-fluorocytosine and to control the digestive absorption of triazoles, especially the lipophilic compound itraconazole.

Phaeohyphomycosis due to Exophiala species: clinical spectrum of disease in humans.
Phaeohyphomycosis caused by Exophiala species is an unusual infection, but it has been reported with increasing frequency as immunosuppressive therapy has become more widespread and laboratory methods for diagnosis have improved. To our knowledge, the first case of subcutaneous phaeohyphomycosis due to Exophiala jeanselmei in a cardiac transplant patient is presented, and previously reported cases of exophiala infection are reviewed. This patient was successfully managed with surgical excision of the lesion and combination therapy with amphotericin B and 5-fluorocytosine.

Cunninghamella bertholletiae: an uncommon agent of opportunistic fungal infection. Case report and review.
Cunninghamella bertholletiae is a fungus of the Zygomycetes class, Mucorales order. Only very few cases of disseminated infection have been reported. We observed a new case in a 19 years old man with severe aplastic anemia, due to pulmonary primoinfection and hematologic dissemination. This aplastic anemia failed to respond first to an antithymocyte globulin and steroid treatment and then to cyclosporine A. Deferoxamine was infused weekly to prevent iron overload. During a second antithymocyte globulin and steroid treatment, the patient developed bilateral pneumonia. Culture of the broncho-alveolar washing fluid established the diagnosis by isolation of C. bertholletiae. Despite amphotericin B and 5-fluorocytosine intravenous therapy, the patient died of disseminated infection six days after diagnosis, which was confirmed by necropsy. Underlying conditions, diagnosis and treatment are discussed, together with a review of the literature.

[Drug surveillance for adverse reactions in patients with human immunodeficiency virus infection].
Human immunodeficiency virus (HIV) carrier patients experience several secondary effects with drugs, being mainly skin reactions and myelosuppression. Owing to this, close observation of patients is necessary with regard to therapeutic and prophylactic schedules. In this paper, we describe the secondary effects of zidovudine in 60 patients of groups III and IV from CDC. The main toxicity was found in bone marrow; with anemia in 50% and leukopenia in 53% of patients. Finally, the more frequent secondary effects of therapy for opportunist infections are analysed. A guide for identifying the drugs' secondary effects is also included, based on our experience and on a wide range of literature reviews.

[Antimycotic therapy].
Because deep opportunistic mycoses are relatively rare, clinicians frequently lack routine in the application of antimycotics. It is the purpose of this review to summarize, from a practical point of view, rationale, indications, applications and toxicity of antimycotic therapy for the mycoses autochthonous to Europe. Amphotericin B remains the standard therapy for most deep opportunistic mycoses, while the newer azoles are the first line agents to be used for superficial forms of candidiasis.

Successful treatment of disseminated Fusarium infection in an immunocompromised child.
We report the first know case of disseminated fungal infection due to Fusarium proliferatum in a bone marrow transplant recipient to our knowledge. Fusarium was cultured from the blood, a paranasal sinus, and necrotic skin lesions. The isolate was sensitive to amphotericin B and on further sensitivity testing, synergy was demonstrated using rifampin in combination with amphotericin B. The patient had this infection while she was receiving alternate-day amphotericin, rifampin, and 5-flucytosine (5-FC) therapy. The infection was documented within 48 h of discontinuing daily granulocyte transfusions, which she had received for 3 weeks. The 5-FC was discontinued when sensitivities showed the organism resistant. After 6 weeks of treatment she showed complete remission of the infection, although neutrophil counts remained below 0.25 X 10(9)/L. From this case and from a review of the literature, it appears that synergic antifungal agents combined with leukocyte transfusions may be beneficial in the successful treatment of fusariosis in the compromised host.

Emergence of a new opportunistic pathogen, Candida lusitaniae.
Candida lusitaniae has been an infrequently reported opportunistic pathogen. Most previously reported cases of serious infection caused by this organism have proven fatal and were associated with amphotericin resistance of the organism. We report two patients with hematologic malignancies undergoing cytotoxic chemotherapy who developed fungemia with this organism while they were granulocytopenic. The organisms isolated from each patient were fully susceptible and were treated successfully with amphotericin B. When isolated from an immunocompromised host, C. lusitaniae should be considered an opportunistic pathogen and undergo antifungal susceptibility testing. Amphotericin B should be considered the drug of choice, but a poor clinical response may be indicative of a resistant isolate.

Candidiasis.
C. albicans and its related species have become major nosocomial causes of morbidity and mortality in the immunocompromised and in other severely ill patients. Diagnosis of the severe forms of the disease remains difficult and depends on the basis of a composite of clinical findings. Treatment for most forms of severe Candida infections remains amphotericin B despite its toxicities. Until more effective prevention of the disease becomes feasible, Candida infections are likely to increase in frequency as major iatrogenic problems.

Trichosporonosis.
Disseminated trichosporonosis due to Trichosporon beigelii is an uncommon but increasingly reported infection in immunocompromised patients. It often presents as fungemia, cutaneous lesions, pulmonary infiltrates, and azotemia. This systemic mycosis is often refractory to conventional antifungal therapy and is frequently fatal.

Zygomycosis.
Zygomycosis represents an excellent example of an opportunistic fungal infection that generally occurs in the debilitated, immunocompromised, or acidotic host. Infections are usually fulminant, with etiologic agents exhibiting predilection for invasion of blood vessels with resultant infarction and necrosis. The spectrum of agents capable of inciding zygomycosis has broadened and the incidence has increased in contemporary medicine. Nevertheless, an increased index of suspicion, better mycological acumen, aggressive surgical debridement of diseased tissue, and prompt therapy with amphotericin B have rendered substantial improvement in the prognosis of an otherwise fatal infectious disease. Rapid and accurate diagnostic techniques and the availability of less toxic, efficacious antifungal agents should be sought after goals for the enhanced management of zygomycosis.

Opportunistic fungal infections in immunocompromised hosts.
Fungal infections in immunocompromised hosts cause major morbidity and mortality. The Candida and Aspergillus species are the most common causes, but many rarer organisms, once considered "contaminants," are being reported. The number of patients who receive immunosuppressive agents for the treatment of malignancy or for organ transplantation is increasing as well as the potential for local or disseminated fungal infections. The diagnosis of these infections is often difficult and the existing methods for treatment are often ineffective. A high degree of suspicion to identify fungal infections and to prompt initiation of treatment must be maintained if the survival rate of these patients is expected to improve.

Systemic candidiasis.
Systemic candidiasis is a disease of increasing incidence and proportions, which appears to be associated with the advances in modern medicine. It involves primarily patients with severe debilitating and malignant disease who are receiving immunosuppressive, cytotoxic, antimetabolite, and antibiotic therapy. Side effects of these otherwise major therapeutic agents predispose patients to opportunistic fungal infections, of which candidiasis is the most common. The high morbidity and mortality of disseminated candidiasis in neutropenic patients are difficult obstacles to obtaining the optimal, if not full, potential of modern chemotherapy for cancer. The inability to diagnose early invasive and systemic candidiasis is a major handicap that delays timely initiation of antifungal therapy. The paucity of highly efficacious antifungal agents with low toxicity severely limits the ability to successfully cure systemic fungal infections in cancer patients. Aggressive research into the basic biology of Candida spp. is necessary for directing the development of better diagnostic methods and improved antifungal drugs.

Candida albicans shunt infection.
Seven cases of successfully treated Candida albicans cerebrospinal fluid shunt infections are reported. Treatment consisted of shunt removal and intravenous Amphotericin B in all cases and intraventricular Amphotericin B in 4 cases. Serious underlying medical illness, recent antibiotic therapy, indwelling intravascular and/or Foley catheters, coincident candidiasis and low birth weight prematurity are major risk factors for candida shunt infection. Candida shunt infection appears to occur by either contamination at the time of shunt placement or by hematogenous dissemination.

Diagnosis and successful treatment of fusariosis in the compromised host.
We present six cases of fusariosis caused by Fusarium solani that were diagnosed over a three-year period in 166 adult patients undergoing chemotherapy for acute leukemia. Necrotic skin lesions were evident in four patients, fungemia in three, and a deep cellulitis around a great toe nail at the time of a febrile illness in two. The mean minimal inhibitory concentration (MIC) of amphotericin B was 3.3 micrograms/mL and of miconazole, 5.3 micrograms/mL; all isolates were resistant to 5-fluorocytosine. All patients received amphotericin B (1.0-1.5 mg/kg per d) plus 5-fluorocytosine. In contrast to results found in the literature, five patients had resolution of their infections, and the one patient who died had necropsy evidence of disseminated fusariosis. Review of our cases and of the literature did not reveal a definitive source for the organism or its portal of entry. Fusarium spp. must be recognized as opportunistic pathogens that cause a potentially fatal infection in compromised patients.

A prospective, randomized study of empirical antifungal therapy for the treatment of chemotherapy-induced febrile neutropenia in children.
Given that the rationale for empirical antifungal therapy in neutropenic children is limited and based on adult patient data, we performed a prospective, randomized, controlled trial that evaluated 110 neutropenic children with persistent fever. Those at high risk for invasive fungal infections (IFI) received caspofungin (Arm C) or liposomal amphotericinB (Arm B); those with a lower risk were randomized to receive Arm B, C, or no antifungal treatment (Arm A). Complete response to empirical antifungal therapy was achieved in 90/104 patients (86·5%): 48/56 at high risk (85·7%) [88·0% in Arm B; 83·9% in Arm C (P = 0·72)], and 42/48 at low risk (87·5%) [87·5% in control Arm A, 80·0% Arm B, 94·1% Arm C; (P = 0·41)]. None of the variables tested by multiple logistic regression analysis showed a significant effect on the probability to achieve complete response. IFI was diagnosed in nine patients (8·2%, 95% confidence interval, 3·8-15·0). This randomized controlled study showed that empirical antifungal therapy was of no advantage in terms of survival without fever and IFI in patients aged <18 years and defined with low risk of IFI. Higher risk patients, including those with relapsed cancer, appear to be the target for empirical antifungal therapy during protracted febrile neutropenia.

Galactomannan-guided preemptive vs. empirical antifungals in the persistently febrile neutropenic patient: a prospective randomized study.
Patients with neutropenic fever after 4-7 days of broad-spectrum antibiotics are given antifungals empirically. This strategy may lead to over-treatment.. Patients with hematological malignancies undergoing intensive chemotherapy or hematopoietic stem cell transplantation were randomized to two arms. Patients in the 'preemptive' arm had regular galactomannan (GM) assays, and received caspofungin, amphotericin or voriconazole (CAV) for persistent febrile neutropenia if they had two positive GM results, or a positive GM result and a computed tomography (CT) of the thorax suggestive of invasive pulmonary aspergillosis (IPA). Patients in the 'empirical' arm received CAV in accordance with established guidelines.. Of 27 episodes in the preemptive arm, two cases of IPA were picked up by monitoring. In six episodes, CAV was started despite persistently negative GM readings. One additional patient received CAV for a false-positive GM. Of 25 episodes in the empirical arm, CAV was started empirically in 10, one of whom had CT features of IPA. By intent-to-treat and evaluable-episode analyses, respectively, the preemptive approach saved 11% and 14% of patients from empirical antifungals. Twelve-week survival was 85.2% in the preemptive arm and 84% in the empirical arm.. A preemptive approach may reduce empirical antifungal use without compromising survival in persistently febrile neutropenic patients.

Feasibility, tolerability, and outcomes of nebulized liposomal amphotericin B for Aspergillus infection prevention in lung transplantation.
Nebulized amphotericin B deoxycholate (n-ABD) is used to prevent Aspergillus infection in lung transplantation. Nebulized liposomal amphotericin B (n-LAB) is another option; however, no clinical data are available on the results of n-LAB for this purpose.. In an observational study performed in 2 centers to assess the feasibility, tolerability, and outcomes of n-LAB prophylaxis, 104 consecutive patients undergoing prophylaxis with n-LAB were compared with 49 historical controls who received n-ABD. Patient follow-up lasted 12 months. The n-LAB prophylaxis regimen was 25 mg thrice weekly starting on the first post-operative day and continuing to 60 days, 25 mg once weekly from 60 to 180 days, and the same dose once every 2 weeks thereafter.. Aspergillus infection developed in 8 of 104 patients (7.7%) with n-LAB prophylaxis (5 colonization, 1 simple tracheobronchitis, 1 ulcerative tracheobronchitis, and 1 invasive pulmonary infection). Ulcerative tracheobronchitis and invasive pulmonary aspergillosis were regarded as invasive disease; hence, the rate of invasive disease was 1.9% (2 patients). The control group had similar rates of Aspergillus infection (10.2%; p = 0.6) and invasive disease (4.1%; p = 0.43). In 3 patients (2.9%), n-LAB was withdrawn due to bronchospasm in 2 and nausea in 1. In the control group, prophylaxis was stopped in 2 patients (4.1%) because of bronchospasm (p = 0.7).. At the dose and frequency described, n-LAB seems effective, safe, and convenient for the prevention of Aspergillus infection in lung transplant patients.

Empirical versus preemptive antifungal therapy for high-risk, febrile, neutropenic patients: a randomized, controlled trial.
Empirical antifungal therapy is the standard of care for neutropenic patients with hematological malignancies who remain febrile despite broad-spectrum antibacterial treatment. Recent diagnostic improvements may ensure the early diagnosis of potentially invasive fungal disease. Reserving antifungals for this stage may achieve similar survival rates and reduce treatment toxicity and costs.. In this multicenter, open-label, randomized noninferiority trial, we compared an empirical antifungal strategy with a preemptive one. Empirical treatment was defined as antibacterial treatment of patients who have persistent or recurrent fever. Preemptive treatment was defined as treatment of patients who have clinical, imaging, or galactomannan-antigen-assay evidence suggesting fungal disease. First-line antifungal treatment was amphotericin B deoxycholate (1 mg/kg/day) or liposomal amphotericin (3 mg/kg/day), depending on daily renal function. The primary efficacy outcome was the proportion of patients alive at 14 days after recovery from neutropenia.. The median duration of neutropenia (neutrophil count, <500 cells/mm3) for the 293 patients enrolled was 18 days (range, 5-69 days). By intention-to-treat analysis, survival was 97.3% with empirical treatment and 95.1% with preemptive treatment. The lower 95% confidence limit for the difference in mortality was -5.9%, which was within the noninferiority margin of -8%. Probable or proven invasive fungal infections were more common among patients who received preemptive treatment than among patients who received empirical treatment (13 of 143 vs. 4 of 150; P < .05), and most infections occurred during induction therapy (12 of 73 patients in the preemptive treatment group vs. 3 of 78 patients in the empirical treatment group were infected during induction therapy; P < .01). Preemptive treatment did not decrease nephrotoxicity but decreased costs of antifungal therapy by 35%.. Preemptive treatment increased the incidence of invasive fungal disease, without increasing mortality, and decreased the costs of antifungal drugs. Empirical treatment may provide better survival rates for patients receiving induction chemotherapy.

Safety and efficacy of itraconazole compared to amphotericin B as empirical antifungal therapy for neutropenic fever in patients with haematological malignancy.
Safety, tolerability and efficacy of itraconazole and amphotericin B (AMB) were compared for empirical antifungal treatment of febrile neutropenic cancer patients.. In an open, randomised study, 162 patients with at least 72 h of antimicrobial treatment received either intravenous followed by oral itraconazole suspension or intravenous AMB for a maximum of 28 days. Permanent discontinuation of study medication due to any adverse event was the primary safety parameter. Efficacy parameters included response and success rate for both treatment groups.. Significantly fewer itraconazole patients discontinued treatment due to any adverse event (22.2 vs. 56.8% AMB; p < 0.0001). The main reason for discontinuation was a rise in serum creatinine (1.2% itraconazole vs. 23.5% AMB). Renal toxicity was significantly higher and more drug-related adverse events occurred in the AMB group. Intention-to-treat (ITT) analysis showed favourable efficacy for itraconazole: response and success rate were both significantly higher than for AMB (61.7 vs. 42% and 70.4 vs. 49.3%, both p < 0.0001). Treatment failure was markedly reduced in itraconazole patients (25.9 vs. 43.2%), largely due to the better tolerability.. Itraconazole was tolerated significantly better than conventional AMB and also showed advantages regarding efficacy. This study confirms the role of itraconazole as a useful and safe agent in empirical antifungal therapy of febrile neutropenic cancer patients.

Liposomal amphotericin B versus the combination of fluconazole and itraconazole as prophylaxis for invasive fungal infections during induction chemotherapy for patients with acute myelogenous leukemia and myelodysplastic syndrome.
Fungal infections are a major cause of morbidity and mortality in patients undergoing induction chemotherapy for acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS). The authors evaluated the efficacy and toxicity of liposomal amphotericin B (L-AmB) compared with a combination of fluconazole plus itraconazole (F+I) as prophylaxis in this setting.. Patients with newly diagnosed AML or high-risk MDS who were undergoing initial induction chemotherapy were randomized to receive either F+I (fluconazole 200 mg orally every 12 hours plus itraconazole tablets 200 mg orally every 12 hours) or L-AmB (3 mg/kg intravenously 3 times per week) in this prospective, open-label study.. Seventy-two L-AmB-treated patients and 67 F+I-treated patients were enrolled in the study. Of these, 47% of patients completed antifungal prophylaxis without a change in therapy for proven or suspected fungal infection. Three patients in each arm developed a proven fungal infection. Twenty-three percent of the L-AmB-treated patients and 24% of the F+I-treated patients were changed to alternative antifungal therapy because of persistent fever (P value not significant). Nine percent of the L-AmB-treated patients developed pneumonia of unknown etiology compared with 16% of the F+I-treated patients (P value not significant). Increases in serum creatinine levels to > 2 mg/dL (20% for the L-AmB arm vs. 6% for the F+I arm; P = 0.012) and increases in serum bilirubin levels to > 2 mg/dL (43% vs. 22%, respectively; P = 0.021) were more common with L-AmB. Infusion-related reactions were noted in five L-AmB-treated patients. Responses to chemotherapy and induction mortality rates were similar for the two arms.. L-AmB and F+I appear similar in their efficacy as antifungal prophylaxis during induction chemotherapy for patients with AML and MDS. L-AmB was associated with higher rates of increased serum bilirubin and creatinine levels.

Comparison of effects of amphotericin B deoxycholate infused over 4 or 24 hours: randomised controlled trial.
To test the hypothesis that amphotericin B deoxycholate is less toxic when given by continuous infusion than by conventional rapid infusion.. Randomised, controlled, non-blinded, single centre study.. University hospital providing tertiary clinical care.. 80 mostly neutropenic patients with refractory fever and suspected or proved invasive fungal infections.. Patients were randomised to receive 0.97 mg/kg amphotericin B by continuous infusion over 24 hours or 0.95 mg/kg by rapid infusion over four hours.. Patients were evaluated for side effects related to infusion, nephrotoxicity, and mortality up to three months after treatment. Analysis was on an intention to treat basis.. Patients in the continuous infusion group had fewer side effects and significantly reduced nephrotoxicity than those in the rapid infusion group. Overall mortality was higher during treatment and after three months' follow up in the rapid infusion than in the continuous infusion group.. Continuous infusions of amphotericin B reduce nephrotoxicity and side effects related to infusion without increasing mortality.

Intravenous and oral itraconazole versus intravenous amphotericin B deoxycholate as empirical antifungal therapy for persistent fever in neutropenic patients with cancer who are receiving broad-spectrum antibacterial therapy. A randomized, controlled tria
Amphotericin B deoxycholate is currently the standard empirical antifungal therapy in neutropenic patients with cancer who have persistent fever that does not respond to antibiotic therapy. However, this treatment often causes infusion-related and metabolic toxicities, which may be dose limiting.. To compare the efficacy and safety of itraconazole with those of amphotericin B as empirical antifungal therapy.. An open randomized, controlled, multicenter trial, powered for equivalence.. 60 oncology centers in 10 countries.. 384 neutropenic patients with cancer who had persistent fever that did not respond to antibiotic therapy.. Intravenous amphotericin B or intravenous itraconazole followed by oral itraconazole solution.. Defervescence, breakthrough fungal infection, drug-related adverse events, and death.. For itraconazole and amphotericin B, the median duration of therapy was 8.5 and 7 days and the median time to defervescence was 7 and 6 days, respectively. The intention-to-treat efficacy analysis of data from 360 patients showed response rates of 47% and 38% for itraconazole and amphotericin B, respectively (difference, 9.0 percentage points [95% CI, -0.8 to 19.5 percentage points]). Fewer drug-related adverse events occurred in the itraconazole group than the amphotericin B group (5% vs. 54% of patients; P = 0.001), and the rate of withdrawal because of toxicity was significantly lower with itraconazole (19% vs. 38%; P = 0.001). Significantly more amphotericin B recipients had nephrotoxicity (P < 0.001). Breakthrough fungal infections (5 patients in each group) and mortality rates (19 deaths in the itraconazole group and 25 deaths in the amphotericin B group) were similar. Sixty-five patients switched to oral itraconazole solution after receiving the intravenous formulation for a median of 9 days.. Itraconazole and amphotericin B have at least equivalent efficacy as empirical antifungal therapy in neutropenic patients with cancer. However, itraconazole is associated with significantly less toxicity.

Fluconazole versus amphotericin B for the prevention of fungal infection in neutropenic patients with hematologic malignancy.
Effective prophylaxis against fungal infection is important in neutropenic patients with hematologic malignancies, but the best method remains unclear. We investigated the effectiveness of fungal prophylaxis with amphotericin B or fluconazole. We reviewed the data on fungal isolates, plasma (1-->3)-beta-D glucan (beta-D glucan) levels, febrile periods (the number of days with an axillary temperature > 38 degrees C), and the duration of an axillary temperature > 38 degrees C when the neutrophil count was < 500/microliter. Of the 124 patients studied, 57 had acute myelogenous leukemia, 19 had acute lymphoblastic leukemia, 18 had non-Hodgkin's lymphoma, six had chronic myeloid leukemia, three had adult T-cell leukemia, and five had chronic lymphocytic leukemia. There were no significant differences in clinical characteristics between the 70 patients treated with amphotericin B and the 54 patients given fluconazole. There was a significant decrease of fungal isolates (chi 2-test, p < 0.001), the plasma beta-D glucan level (Wilcoxon test, p = 0.0001), and the febrile period (t-test, p < 0.05) in the patients given fluconazole compared with those given amphotericin B. In neutropenic patients with hematologic malignancies, prophylaxis with fluconazole significantly decreased fungal isolation and other indicators of fungal infection when compared with amphotericin B. Fluconazole may therefore be more effective for fungal prophylaxis in these patients.

Randomized, double-blind clinical trial of amphotericin B colloidal dispersion vs. amphotericin B in the empirical treatment of fever and neutropenia.
We conducted a prospective, randomized, double-blind study comparing amphotericin B colloidal dispersion (ABCD) with amphotericin B in the empirical treatment of fever and neutropenia. Patients with neutropenia and unresolved fever after > or = 3 days of empirical antibiotic therapy were stratified by age and concomitant use of cyclosporine or tacrolimus. Patients were then randomized to receive therapy with ABCD (4 mg/[kg.d]) or amphotericin B (0.8 mg/[kg.d]) for < or = 14 days. A total of 213 patients were enrolled, of whom 196 were evaluable for efficacy. Fifty percent of ABCD-treated patients and 43.2% of amphotericin B-treated patients had a therapeutic response (P = .31). Renal dysfunction was less likely to develop and occurred later in ABCD recipients than in amphotericin B recipients (P < .001 for both parameters). Infusion-related hypoxia and chills were more common in ABCD recipients than in amphotericin B recipients (P = .013 and P = .018, respectively). ABCD appeared comparable in efficacy with amphotericin B, and renal dysfunction associated with ABCD was significantly less than that associated with amphotericin B. However, infusion-related events were more common with ABCD treatment than with amphotericin B treatment.

Liposomal amphotericin B compared with amphotericin B deoxycholate in the treatment of documented and suspected neutropenia-associated invasive fungal infections.
It has been suggested that a better outcome of neutropenia-associated invasive fungal infections can be achieved when high doses of lipid formulations of amphotericin B are used. We now report a randomized multicentre study comparing liposomal amphotericin B (AmBisome, 5 mg/kg/d) to amphotericin B deoxycholate (AmB, 1 mg/kg/d) in the treatment of these infections. Of 106 possible patients, 66 were enrolled and analysed for efficacy: nine had documented fungaemia, 17 had other invasive mould infections and 40 had suspected pulmonary aspergillosis. After completion of the course medication, in the AmBisome group (n = 32) 14 patients had achieved complete response, seven a partial response and 11 were failures as compared to 6, 13 and 15 patients (n = 34) treated with AmB (P=0.09); P=0.03 for complete responders. A favourable trend for AmBisome was found at day 14, in patients with documented infections and in patients with pulmonary aspergillosis (P=0.05 and P=0.096 respectively). Mortality rates were lower in patients treated with AmBisome (adjusted for malignancy status, P=0.03). More patients on AmB had a >100% increase of their baseline serum creatinine (P<0.001). The results indicate that, in neutropenic patients with documented or suspected invasive fungal infections AmBisome 5 mg/kg/d was superior to AmB 1 mg/kg/d with respect to efficacy and safety.

Fluconazole versus amphotericin B as empirical antifungal therapy of unexplained fever in granulocytopenic cancer patients: a pragmatic, multicentre, prospective and randomised clinical trial.
Amphotericin B, despite its intrinsic servere toxicity, is the most commonly used empirical antifungal therapy in cancer patients with unexplained fever not responding to empirical antibacterial therapy. The aim of this study was to show whether fluconazole was as effective as, and less toxic than, amphotericin, with no effort made to compare the antifungal activity of the two drugs. A group of 112 persistently febrile (> 38 degrees C) and granulocytopenic (< 1000 cells/mm3) cancer patients, not receiving any absorbable antifungal antibiotic for prophylaxis, with a mean age of 27 years (range 1-73 years), undergoing chemotherapy for a variety of malignancies and with a diagnosis of unexplained fever after at least 96 h of empirical antibacterial therapy, were randomised to receive either fluconazole (6 mg/kg/day up to 400 mg/day) or amphotericin B (0.8 mg/kg/day) as empirical antifungal treatment. Patients were required to have normal chest X-rays at randomisation, no previous history of aspergillosis and negative surveillance cultures for Aspergillus. The intention-to-treat analysis showed defervescence and survival without treatment modification in 42 of 56 patients (75%) in the fluconazole group and in 37 of 56 (66%) in the amphotericin B group (P = 0.4). Duration of therapy was 6 days (95% CI = 4-8 days) in both groups. Death occurred in 3 patients (5%) in the fluconazole and in 2 (4%) in the amphotericin B group. No fungal death was documented in either group. Adverse events developed in 18 of 56 patients (32%) in the fluconazole group and in 46 of 56 (82%) in the amphotericin B group (P < 0.001). In the amphotericin B group, 5 patients had treatment discontinued because of toxicity, versus none in the fluconazole group, a difference which approached statistical significance (P = 0.06). This study shows that fluconazole is by far less toxic than amphotericin B and suggests that it might be as effective as amphotericin B, in pragmatical terms and for this specific indication. However, numbers are too small to allow definitive conclusions about efficacy, and the use of fluconazole for this indication remains experimental. Future studies should try to identify patients more at risk of fungal infections, with the aim of individualising antifungal approaches.

Efficacy and safety of fluconazole prophylaxis for fungal infections after marrow transplantation--a prospective, randomized, double-blind study.
A randomized, double-blind, placebo-controlled trial assessed the efficacy and toxicity of 400 mg/day fluconazole in preventing fungal infections during the first 75 days after marrow transplantation. During prophylaxis, systemic fungal infections occurred in 10 (7%) of 152 fluconazole-treated patients compared with 26 (18%) of 148 placebo-treated patients (P = .004). There were no Candida albicans infections in fluconazole recipients compared with 18 in placebo recipients (P < .001) and no significant increase in Candida infections other than C. albicans. Fluconazole also significantly reduced the incidence of superficial fungal infections (P < .001), fungal colonization (P = .037), and empiric amphotericin B use (P = .005). The probability of survival was improved in fluconazole recipients, in whom 31 deaths occurred up to day 110 after transplantation compared with 52 deaths in placebo recipients (P = .004). No clinically significant toxicity was detected with fluconazole use. Prophylactic fluconazole was safe and significantly reduced systemic fungal infections with other benefits, including improved survival at day 110 after marrow transplantation.

Liposomal amphotericin B prevents invasive fungal infections in liver transplant recipients. A randomized, placebo-controlled study.
Eighty-six consecutive liver transplant recipients were prospectively randomized in a double-blind, placebo-controlled antifungal prophylaxis study. Seventy-seven patients received 5 days of prophylaxis starting during the transplantation with either liposomal amphotericin B (AmBisome) 1 mg/kg/day or placebo. Among 40 AmBisome-treated patients, no invasive Candida infection was seen during the first month, compared with 5 invasive Candida albicans infections among 37 control patients (P < 0.05). Furthermore, 1 placebo patient experienced Aspergillus niger pneumonia. Thus, the overall incidence of invasive fungal infections was 0/40 (0%) in the AmBisome group versus 6/37 (16%) in the placebo group (P < 0.01). Patient survival at 30 days was 92% versus 94% for AmBisome- and placebo-treated patients, respectively. One patient experienced backache related to AmBisome infusion. Two patients had transient thrombocytopenia possibly caused by AmBisome treatment. AmBisome was otherwise well tolerated. The total cost for all antifungal drugs used in both groups was equal. However, prophylaxis with AmBisome was $5000 less expensive than treatment of proven invasive fungal infections among placebo patients.

Itraconazole compared with amphotericin B plus flucytosine in AIDS patients with cryptococcal meningitis.
We conducted a comparison of itraconazole versus amphotericin B plus flucytosine in the initial treatment of cryptococcal meningitis in patients with AIDS and established the efficacy of itraconazole as maintenance treatment.. The trial was a prospective, randomized, and non-blinded study.. The study was performed at an academic centre for AIDS, Amsterdam, The Netherlands.. Twenty-eight HIV-1-seropositive men with a presumptive diagnosis of cryptococcal meningitis, randomized between 5 February 1987 and 1 January 1990, were included for analysis.. Oral itraconazole (200 mg twice daily), versus amphotericin B (0.3 mg/kg daily) intravenously plus oral flucytosine (150 mg/kg daily) was administered for 6 weeks followed by maintenance therapy with oral itraconazole (200 mg daily) to all patients.. Outcome measures were a complete or partial response, recrudescence and relapse.. A complete response was observed in five out of the 12 patients who completed 6 weeks of initial treatment with itraconazole versus all 10 patients who completed treatment with amphotericin B plus flucytosine (P = 0.009). A partial response was observed in seven out of the 14 patients assigned to itraconazole. During maintenance therapy, recrudescence (n = 6) or relapse (n = 1) occurred in seven out of the 12 patients initially assigned to itraconazole, whereas two relapses occurred among nine patients initially treated with amphotericin B plus flucytosine (P = 0.22); recurrence of clinical symptoms was significantly related to a positive cerebrospinal fluid culture at 6 weeks (P = 0.003).. Itraconazole is less effective compared with amphotericin B plus flucytosine in achieving a complete response in initial therapy in AIDS patients with cryptococcal meningitis.

A pilot study of prophylactic aerosolized amphotericin B in patients at risk for prolonged neutropenia.
Invasive aspergillosis continues to be a significant cause of morbidity and mortality in patients with prolonged neutropenia. We performed a phase I trial of escalating doses of aerosolized amphotericin B given by a face mask nebulizer system with a disposable bacterial exhale filter. Five, 10, 15, and 20 mg of drug were dissolved in sterile water and inhaled over 10 to 15 minutes twice daily. Tolerance was studied in 26 patients (18 transplant recipients, and 8 leukemia patients). No side effects were observed at any dose level. Prophylactic treatment ended for 14 patients (54%) when intravenous (IV) amphotericin B was begun empirically for antifungal coverage following fevers. Eleven patients (43%) continued inhaled amphotericin B until blood counts recovered. One patient was taken off study when she developed cardiogenic pulmonary edema. No patient developed clinically suspicious or pathologically documented infection with invasive aspergillosis. Prophylactic aerosolized amphotericin B is well tolerated at 5, 10, 15, and 20 mg twice daily dosing. In addition, prophylactic aerosolized amphotericin B does not appear to sensitize patients to the subsequent use of IV amphotericin B. Although this study suggests that prophylactic inhaled amphotericin B is well tolerated and effective, a large scale controlled trial is needed.

Fluconazole compared with amphotericin B plus flucytosine for cryptococcal meningitis in AIDS. A randomized trial.
To compare the efficacy of fluconazole with amphotericin B plus flucytosine in the treatment of cryptococcal meningitis.. Patients were randomly assigned to oral fluconazole, 400 mg/d, for 10 weeks or to amphotericin B, 0.7 mg/kg body weight daily for 1 week, then three times weekly for 9 weeks combined with flucytosine, 150 mg/kg d, in four divided doses.. Los Angeles County-University of Southern California Medical Center.. Between 15 February and 7 December 1988, 42 patients had evidence of their first episode of cryptococcal meningitis, of whom 21 participated in the trial. All patients enrolled were men with the acquired immunodeficiency syndrome (AIDS) except one woman who was receiving prednisone therapy and was excluded from the final analysis.. Of 14 patients with AIDS assigned to fluconazole, 8 (57%; 95% CI, 29% to 82%) failed; none of the 6 patients with AIDS failed who were assigned to amphotericin B plus flucytosine therapy (0%; CI, 0% to 46%) (Fisher exact test, P = 0.04). The mean duration of positive cerebrospinal fluid cultures was 40.6 +/- 5.4 days in patients receiving fluconazole and 15.6 +/- 6.6 days in patients receiving amphotericin B plus flucytosine (Mann-Whitney test, P = 0.02). Overall, 4 patients assigned to fluconazole therapy died whereas no patient assigned to amphotericin B plus flucytosine therapy died (Fisher exact test, P = 0.27).. Amphotericin B used in combination with flucytosine has superior mycologic and clinical efficacy compared with fluconazole for the treatment of cryptococcal meningitis in patients with AIDS.

Intracranial Epstein-Barr virus-associated smooth muscle tumor with superimposed cryptococcal infection: A case report.
Epstein-Barr virus-associated smooth muscle tumors (EBV-SMT) are rare, virally-induced malignancies that occur almost exclusively in immunocompromised individuals. We report a very rare case of a dura-based EBV-SMT with superimposed local cryptococcal infection.. An adult male with a history of untreated acquired immunodeficiency syndrome presented to our hospital with worsening headaches, diarrhea, and diffuse myalgias.. Blood cultures were positive for methicillin-resistant Staphylococcus aureus and Cryptococcus neoformans serum antigen. Magnetic resonance imaging revealed 2 adjacent enhancing masses in the right temporal lobe, perilesional edema, and mass effect of the right lateral ventricle. Histological examination and immunohistochemical stains of the surgical specimen were consistent with EBV-SMT. Cryptococcus organisms were identified within the neoplasm.. The patient underwent complete tumor resection, received an extended course of amphotericin and flucytosine, and was restarted on antiretroviral therapy.. The patient was discharged from the hospital with no focal neurological deficits.. Epstein-Barr virus associated smooth muscle tumors are rare malignancies that occur in immunocompromised patients. Prognosis is largely dependent on immune reconstitution and treatment of concomitant infections.

Mucormycosis with cutaneous involvement. A retrospective study of 115 cases at a tertiary care hospital in Mexico.
Cutaneous mucormycosis is an emerging opportunistic mycosis caused by Mucorales. It can be divided into primary caused by trauma and secondary by extension of rhino-cerebral and disseminated cases. The objective is to present a retrospective study of cases of mucormycosis with cutaneous involvement.. A retrospective and descriptive study was carried out. Mucormycosis patients were included and divided into two groups: a) Primary Cutaneous and b) Secondary Cutaneous. Mycological tests were performed; the agents were identified by morphology and molecular studies (PCR and sequencing); some cases underwent histopathology. Clinical data and response to treatment were collected.. 115 cases were included, 18 of primary, and 97 of secondary cutaneous mucormycosis. Primary cutaneous mucormycosis was most associated with adhesive bands (44.4%) and trauma from traffic accidents (33.3%). The principal clinical form was extensive and deep necrotic ulcers. Secondary cutaneous mucormycosis cases were rhino-cerebral with uncontrolled diabetes (81.4%) The most frequent clinical presentation was necrosis of the eyelid and the nose (65.9%). In both groups, the principal agent was Rhizopus arrhizus, 38.8% and 74.2% respectively. The most effective treatment was the combination of amphotericin B with surgical debridement. The clinical and mycological cure was achieved in 31.0% of primary cases, and 44.4% for secondary cases.. Primary cutaneous mucormycosis is caused by implantation of the Mucorales due to trauma or rupture of the cutaneous barrier-breach, and secondary cutaneous mucormycosis develops as part of the rhino-cerebral process. The response to treatment depends on the extension and depth, as well as the predisposing factors.

Frequency of occurrence, seasonal variation and antifungal susceptibility of opportunistic Mucorales isolated from hospital soils in Iran.
Mucorales are opportunistic pathogens that can cause life-threatening diseases predominantly in immunocompromised patients.. This study aimed to investigate the frequency, seasonal variation and antifungal susceptibility of pathogenic Mucorales in the soil collected from seven hospitals in Urmia, Iran, between November 2017 and July 2018 in four different seasons.. Mucorales isolates obtained from soil were characterised based on conventional and molecular assays. In addition, in vitro antifungal susceptibility was performed using the CLSI M38Ed3 procedure.. Out of 196 tested soil samples, 80 (40.8%) samples were positive for mucoralean fungi. Rhizopus arrhizus var. arrhizus (n = 47) was the most frequent species followed by Mucor circinelloides (n = 21) and Cunninghamella echinulata (n = 6). A seasonal variation in the frequency of Mucorales in soil was detected with a maximum of culture-positive soil samples detected in wet autumn (43.2%) followed by winter (23.4%), summer (19.7%) and spring (13.6%). In vitro antifungal susceptibility testing for 80 environmental isolates exhibited MIC of ≤2 μg/ml for amphotericin B indicating the smallest range of MIC variation among the tested Mucorales (range: 0.125-2 μg/ml). Among the azoles, posaconazole was the most effective antifungals (GM MIC, 0.724 μg/ml).. We considered associations of species and seasonal frequencies between soil mucoralean fungi and mucormycosis. The effect of opportunistic Mucorales dominating in the soil and prevalent causative agents of mucormycosis in Iran reported in the literatures but more comprehensive studies are needed to confirm this conclusion.

Concomitant BK virus infection and visceral Leishmaniasis in a pediatric liver transplant recipient.
Solid organ transplant recipients are vulnerable to various unusual infections. Visceral Leishmaniasis (VL) is a protozoal opportunistic infection, which may affect the immune-suppressed hosts and solid organ transplant recipients. The BK virus infection is an evolving challenge in kidney transplant recipients. However, there are very few reports of BK virus (BKV) nephropathy involving the native kidney in liver transplant recipients. To the best of our knowledge, this is the first report of the simultaneous occurrence of these rare infections in a liver transplant recipient.. The patient was a 9-year-old girl, a case of liver transplantation who presented with the incidental finding of proteinuria, azotemia, and cytopenia. Investigations revealed that she had concomitant BKV nephropathy and visceral leishmaniasis. Both infections were successfully treated.. BK virus should be considered as a cause of nephropathy in liver transplant recipients. The presenting features of fever, cytopenia, and splenomegaly in a post-transplant patient should remind of unusual infections such as VL other than the common post-transplant conditions.

Identification of Off-Patent Drugs That Show Synergism with Amphotericin B or That Present Antifungal Action against Cryptococcus neoformans and
Amphotericin B (AmB) is the antifungal with the strongest fungicidal activity, but its use has several limitations, mainly associated with its toxicity. Although some lipidic and liposomal formulations that present reduced toxicity are available, their price limits their application in developing countries. Flucytosine (5FC) has shown synergistic effect with AmB for treatment of some fungal infections, such as cryptococcosis, but again, its price is a limitation for its use in many regions.

Multiresistent opportunistic talaromycosis in a patient with ovarian cancer.
Talaromycosis (penicillinosis) is multiresistent opportunistic mycosis. The infection can be inapparent and it can simmulate malignant tumor dissemination in some patients.. We present a case of 33-years-old patient with mucinous adenocarcinoma of left ovary, initially FIGO IIC. The patient had had hysterectomy, bilateral adnexectomy, omentectomy and port-site metastasis extirpation. Six cycles of 1st chemother-apy paclitaxel and carboplatin had been administered to patient follow-ing the surgery. Positron emission tomography / computed tomography (PET/CT) scan after the treatment, had shown metabolic activity infiltrat-ing both lung apexes, supposedly with no dis-ease correlation, and hypermetabolic foci in spleen, suspicious of be-ing metastases. Pa-cient showed no clinical symp-toms, nor markers of inflammation elevation. Initially elevated serum tumor markers CA125 and CA72-4 had decreased after the treatment. Bronchoalveolar lavage cytology described presence of inflammatory infiltration with fungiform-ing hyphae - most probably an aspergillosis. Mannan and galactomannan serology was negative. In regard to splenectomy plans, treatment with voriconazol was initiated empirically. Result of fungi cultivation out of bronchoalveolar lavage was finalized later, show-ing sporadic presence o Penicillium sp. with resistance to antimycotic treatment except for amphotericin B. Liposomal amphotericin B treatment was administered in two cures, 28 days in total. Immunomodulatory treatment of secondary cellular immunodeficiency and vaccination against encapsulated bacteria was given to the patient. Splenectomy was performed 6 months after the end of chemother-apy treatment. Histopathology showed chronic granulomatous inflammation without mycotic hyphae, with no evidence of tumor cells. After the splenectomy, patient was treated by surgical incision and drainage and by klindamycin for intraabdominal abscess in left hypogastric area.. Patient is under follow up by oncologist, immunologist and gynecologist 12 months after the splenectomy, she is surveilled by PET/CT and serum tumor markers. Talaromycosis can be clinically inapparent in spite of its dissemination. It can be present in diffuse, granulomatous and mixed form. Therapeutic agent is sometimes limited to amphotericin B due to its resistence. Liposomal form of amphotericin B is recommended regard-ing its pharmacokinetic properties. In case of dissemination, administration period of more than 14 days is recommended, even in inapparent form. Immunomodulatory treatment is recommended due to opportunistic infection.

Invasive Curvularia Infection in Pediatric Patients With Hematologic Malignancy Identified by Fungal Sequencing.
Curvularia is a saprophytic dematiaceous mold and a rare human pathogen. Here, we report three severely immunocompromised pediatric patients who developed invasive Curvularia infection. Diagnosis was achieved or confirmed in all cases by fungal ribosome sequencing, which hastened species identification and targeted treatment for the patients reported. There are no treatment guidelines for invasive Curvularia infection, though we report three patients who were cured of their infection through a combination of surgical resection and various anti-fungal therapies, indicating a relatively low virulence and good prognosis in comparison to other angioinvasive molds.

Multifocal muscle candidiasis of the legs in a patient with acute myeloid leukemia: A case report.
Opportunistic infections frequently develop in immunocompromised patients, such as those with hematological malignancies, causing significant mortality. Early diagnosis of invasive fungal infections is often important and difficult due to the difficult nature of confirming infection using cytologic and histologic findings. However, we report the first case of candidal infection leading to muscle abscesses in the legs of a patient with leukemia.. A 60-year-old man with acute myeloid leukemia (AML) presented with multifocal muscle abscesses of the legs.. Multifocal muscle candidiasis of the legs was confirmed by fine-needle aspiration biopsy of 2 of the calf lesions.. After treatment with amphotericin B and flucytosine for 1 month, the patient was administered intravenous caspofungin for 3 months.. A CT scan of the abdomen and an MRI of the lower calves showed significant improvement.. This case highlights that fungal infection should be considered when patients present with multiple abscesses, emphasizing the value of early biopsy to confirm diagnosis and facilitate precision treatment.

Overview and outcome of mucormycosis among children with cancer: Report from the Children's Cancer Hospital Egypt.
Mucormycosis represents a real challenge in immunocompromised patients. This study aimed to describe the clinical characteristics, treatment outcome and infection-related mortality in our patients at the Children's Cancer Hospital 57357, Cairo, Egypt. This is a retrospective study during the period 2007-2017. Data analysis included demographic data, risk factors, diagnostic workup, treatment and outcome. During the study period, 45 patients developed proven mucormycosis according to EORTC/MSG criteria (2008). Ninety percentof cases were of haematological malignancies. Liposomal amphotericin B was the mainstay of treatment. Posaconazole was used as secondary prophylaxis in 35% of cases. Combination antifungal was used in three cases with progressive mucormycosis. Surgical intervention was achievable in 50% of cases. Therapy was successful in 35 patients (66%). Complications related to mucormycosis were seen in five cases with disfigurement and perforated hard palate. Chemotherapy delay with subsequent relapse of primary malignancy was reported in one case. Mucormycosis-related mortality was 33% (15 cases). Mucormycosis is a major cause of mortality among patients with haematological malignancies. Early diagnosis of Mucormycosis infection, with rapid initiation of appropriate antifungal therapy and surgical intervention, whenever feasible, is the backbone of mucormycosis treatment.

Rare presentation of cryptococcal meningitis in an immunocompetent patient.
Cryptococcal meningitis is an opportunistic infection predominantly affecting immunocompromised patients but rarely can affect the immunocompetent. We describe a 53-year-old Caucasian man who presented complaining of a 2-week history of severe bilateral eye pain and diplopia. His only known risk factor was that he lived in a horse farm and recently shot bats and pigeons in his barn. He visited an outside hospital during this time without a diagnosis established. After further deliberation, we obtained a lumbar puncture (LP) which revealed an opening pressure (OP) of 27 cm H Topics: Agricultural Workers' Diseases; Amphotericin B; Antifungal Agents; Cryptococcus neoformans; Diplopia; Drug Therapy, Combination; Eye Pain; Fluconazole; Humans; Immunocompetence; Male; Meningitis, Cryptococcal; Meningoencephalitis; Middle Aged; Opportunistic Infections; Rare Diseases | 2019 |
Isolated splenic mucormycosis in a case of aplastic anaemia.
Mucormycosis, a rare opportunistic infection seen in immunocompromised hosts, is caused by fungi of Mucorales family. It may be confined to the organs, such as rhinocerebral and pulmonary mucormycosis, or may cause disseminated infection. A 14-year-old boy presented to our clinic with fever and left upper quadrant abdominal pain, and on evaluation was found to have pancytopaenia, and imaging revealed ill-defined splenic collection with thrombus in the splenic vein. He was started on empirical intravenous antibiotics, followed by antifungals empirically as he did not show any improvement clinically. Eventually, splenectomy was done, which on histopathological examination revealed mucormycosis. The patient finally succumbed to his illness as he developed peritonitis and refractory shock. To date, only two cases of isolated splenic mucormycosis have been reported. Aggressive treatment is needed, which includes the use of antifungals (amphotericin B) and surgical debridement or resection of the involved tissues or organs.

Mucormycosis is a rare but fulminant opportunistic fungal infection, which occurs most often in diabetic and immunocompromised patients. Dental extractions may create a portal of entry for the fungal infection. The mucormycosis may be the original cause of the pain and can be misdiagnosed as dental pain. In this paper, two cases of mucormycosis are reported after dental extractions and successfully treated with amphotericin B (case #1) and combined with posaconazole (case #2). The two cases we describe exemplify the fulminant mucormycosis of maxillary sinuses after dental extraction inpatients with uncontrolled diabetic support the findings that this predisposing condition created a suitable environment for the Mucorales growth. These case reports emphasize early recognition and urgent treatment of mucormycosis is necessary to prevent the spread of infection Therefore, dental surgeons and healthcare practitioners should become familiar with mucormycosis.

Disseminated histoplasmosis mimicking relapsed chronic lymphocytic leukaemia.
Histoplasma microconidia when inhaled are presented in antigenic form to T cells, limiting the extent of infection; however, defects in cellular immunity results in disseminated disease. Chronic lymphocytic leukaemia (CLL) is a lymphoproliferative disorder resulting in functionally impaired lymphocytes, predisposing patients to various opportunistic infections. The author reports a recently treated patient with CLL presenting with constitutional symptoms accompanied by hepatosplenomegaly and diffuse adenopathy. Considering the recent diagnosis and treatment of CLL, initial suspicion was relapsed disease. However, considering the immune deficiency associated with CLL and its treatment, infectious aetiologies were strongly considered. Further investigation revealed a case of disseminated histoplasmosis mimicking CLL in this reported patient. Considering appropriate diagnosis and timely therapy, the reported patient had good prognosis despite being diagnosed with disseminated histoplasmosis. This case highlights consideration of disseminated histoplasmosis in patients presenting with diffuse adenopathy along with hepatomegaly and/or splenomegaly in the right clinical setting.

The small lymphocytic lymphoma is a mature B cell neoplasm with a broad spectrum of clinical presentations. Opportunistic infections that are not related to the treatment, even in advanced stages, have a low incidence rate. There are few case reports in the medical literature of patients who have not received immunosuppressive therapy and present with small lymphocytic lymphoma associated with disseminated histoplasmosis at diagnosis.\ A female 82-year-old patient was admitted due to an intermittent dry cough, asthenia, and adynamia that had persisted for one month. Multiple studies to detect infections and immuno-rheumatic conditions were performed and an extensive cervical, thoracic and peritoneal adenopathic syndrome was diagnosed.\ A flow cytometry and a cervical lymph node biopsy were performed reporting CD19+, CD20dim, CD5+, CD45+, CD23+, CD43neg, and CD10neg phenotypes with restriction in the light kappa chain compatible with a small lymphocytic lymphoma.\ Epithelioid granulomas without necrosis were observed in the lymph node histopathology and special colorations showed no microorganisms. The culture from the lymph node was positive for Histoplasma capsulatum. We initiated treatment with amphotericin B and itraconazole with an adequate response. In the absence of compliance with oncology treatment criteria, the patient was managed on a “watch and wait” basis.\ Opportunistic infections could be the initial clinical manifestation in patients with low-grade lymphoproliferative syndromes. This case report shows that they can develop even in the absence of chemotherapy.

Successful Treatment of Rhino-Orbital-Cerebral Mucormycosis in a Child With Leukemia.
Rhino-orbital-cerebral mucormycosis (ROCM) is a rare fulminant opportunistic fungal infection that despite relevant treatment has high mortality. We present a case of a 3-year-old girl with acute lymphoblastic leukemia and ROCM, who was treated successfully with excessive surgery, systemic antifungal treatment with amphotericin B (AmB), posaconazole, and terbinafine as well as hyperbaric oxygen. Surgery included, beside extracranial and intracranial removal of infected areas, endoscopic sinus and skull base surgery with local AmB installation and in addition placement of an Ommaya reservoir for 114 intrathecal administrations of AmB. In addition, we review the literature of ROCM in pediatric patients with hematological diseases.

Suspected Pulmonary Infection with Trichoderma longibrachiatum after Allogeneic Stem Cell Transplantation.
Aspergillus and Candida species are the main causative agents of invasive fungal infections in immunocompromised human hosts. However, saprophytic fungi are now increasingly being recognized as serious pathogens. Trichoderma longibrachiatum has recently been described as an emerging pathogen in immunocompromised patients. We herein report a case of isolated suspected invasive pulmonary infection with T. longibrachiatum in a 29-year-old man with severe aplastic anemia who underwent allogeneic stem cell transplantation. A direct microscopic examination of sputum, bronchoaspiration, and bronchoalveolar lavage fluid samples revealed the presence of fungal septate hyphae. The infection was successfully treated with 1 mg/kg/day liposomal amphotericin B.

In vitro activities of five antifungal agents against 199 clinical and environmental isolates of Aspergillus flavus, an opportunistic fungal pathogen.
Aspergillus flavus is the second leading cause of invasive and non-invasive aspergillosis, as well as the most common cause of fungal sinusitis, cutaneous infections, and endophthalmitis in tropical countries. Since resistance to antifungal agents has been observed in patients, susceptibility testing is helpful in defining the activity spectrum of antifungals and determining the appropriate drug for treatment. A collection of 199 clinical and environmental strains of Aspergillus flavus consisted of clinical (n=171) and environmental (n=28) were verified by DNA sequencing of the partial b-tubulin gene. MICs of amphotericin B, itraconazole, voriconazole, posaconazole, and MEC of caspofungin were determined in accordance with the Clinical and Laboratory Standards Institute M38-A2 document. Caspofungin, followed by posaconazole, exhibited the lowest minimum inhibitory concentrations (MIC). All isolates had caspofungin MEC90 (0.063μg/ml) lower than the epidemiologic cutoff values, and 3.5% of the isolates had amphotericin B MIC higher than the epidemiologic cutoff values. However, their clinical effectiveness in the treatment of A. flavus infection remains to be determined.

Bipolaris oryzae, a novel fungal opportunist causing keratitis.
We report a case of mycotic keratitis caused by Bipolaris oryzae with predisposing trauma from a foreign body. The fungus was identified by sequencing the internal transcribed spacer region, translation elongation factor 1α (TEF1) gene, and partial glyceraldehyde-3-phosphate dehydrogenase (GPDH) gene, and the species identity was confirmed on the basis of its characteristic conidial phenotype. The patient was treated with surgical intervention and antifungal agents, including intravenous fluconazole (FLC), oral itraconazole, topical 0.15% amphotericin B eye drops, and 0.5% FLC eye drops. To our knowledge, this is the first report of mycotic keratitis caused by B. oryzae worldwide.

Virulence Attributes and Antifungal Susceptibility Profile of Opportunistic Fungi Isolated from Ophthalmic Infections.
Investigations of both virulence factors and antifungal susceptibility profiles are crucial for understanding the pathogenesis and prognosis of ophthalmic mycoses. In this study, we investigated the in vitro antifungal susceptibility of amphotericin B (AMB), voriconazole (VRC), and natamycin (NAT) against a set of 50 fungal isolates obtained from patients with ocular mycoses using the Clinical and Laboratory Standards Institute broth microdilution method. In addition, putative virulence factor, such as secretory phospholipases and proteinases, and biofilm formation activity were analyzed. The geometric means (GMs) of the minimum inhibitory concentrations (MICs) of the antifungals across all isolates were the following (in increasing order): VRC (0.70 μg/mL), AMB (0.81 μg/mL), and NAT (1.05 μg/mL). The highest activity against 14 Aspergillus strains was exhibited by VRC (GM MIC: 0.10 μg/mL), followed by AMB and NAT (GM MICs: 0.21 and 0.27 μg/mL), respectively. However, for 12 Fusarium spp., the GM MIC of VRC (2.66) was higher than those of NAT and AMB (GM MICs 1.3 and 0.8 μg/mL, respectively). Proteinase and phospholipase activity were observed in 30 % and 42 % of the isolates, respectively, whereas only 8 % of the isolates were able to produce biofilms. Phospholipase activity was observed in all Fusarium isolates, but not in any of the Aspergillus isolates. In contrast, biofilm-forming capability was detected in 25 % of the Fusarium isolates, but none of the Aspergillus isolates. The differences in the MICs of AMB, VRC, and NAT, biofilm-forming ability and proteinase and phospholipase activities among the isolates were not significant (p > 0.05). Overall, our study suggests no significant correlation between the antifungal susceptibility profiles and virulence attributes of ocular fungal isolates.

Disseminated mucormycosis (DM) after pneumonectomy: a case report.
Mucormycosis is a kind of rare opportunistic fungal disease and the incidence of which has gradually increased. Disseminated mucormycosis (DM) is a life-threatening infection that mostly occurs in immunocompromised patients. The lung and brain are usually involved in disseminated mucormycosis, and other sites are scare. We report the first case of disseminated mucormycosis whose infection sites included lung, skin, liver, vertebra, and spinal cord that ensued after a right lung pneumonectomy in an immunocompetent patient.. A 20-year-old female underwent a right lung pneumonectomy for "lung cancer" presented with an intermittent fever for two years. A computed tomography (CT) scan showed an enclosed outstanding mass in the right chest wall. The patient also suffered from lower limb numbness and weakness, difficulty walking, and dysuria. Medical examination showed superficial feeling of the abdominal wall was decreased from the T7 and T8 level; muscle strength for both lower limbs was decreased; muscle tension of both lower limbs was also diminished. A biopsy through the right chest wall mass and thoracic mass by fistula of chest wall showed broad nonseptate hyphae with right-angle branching, consistent with mucormycosis. With titration of amphotericin B and its lipid complex, the patient recovered.. Our case showed an unusual clinical presentation of disseminated mucormycosisin an immunocompetent patient.

[A rare and mortal infection agent in patients with hematological malignancies: Saprochaete capitata].
Saprochaete capitata (formerly known as Geotrichum capitatum and Blastoschizomyces capitatus) is a rare invasive fungal agent that may lead to mortal clinical course in patients with hematological malignancies. This agent can be colonized in skin, lungs and intestines, and it can cause major opportunistic infections. Invasive systemic infections due to S.capitata have been reported in immunosuppressed patients. In this report, two patients with invasive S.capitata infections detected during the course of persistent neutropenic fever in acute leukemia, were presented. In both cases empirical caspofungin was added to the treatment, as no response was obtained by board-spectrum antibacterial therapy in neutropenic fever. In the first patient, there were no significant findings except the chronic inflammation observed in the biopsies which was performed for the symptoms of lymphadenitis, myositis, and hepatosplenic candidiasis. While persistent fever was on going, S.capitata was isolated from the blood and catheter cultures. There was no response after catheter removing and the introduction of amphotericin B and voriconazole therapy, therefore allogeneic stem cell transplantation plan for the second time for bone marrow aplasia was taken an earlier time. However, the patient died due to progressive pericardial and pleural effusion and multiorgan failure, although an afebrile process after stem cell transplantation could be obtained. Similarly the second patient had persistent fever despite empirical caspofungin treatment. The additional symptoms of diarrhea, abdominal pain and subileus have indicated an intraabdominal infection. During the follow up, S.capitata was isolated from the blood and catheter cultures. Catheter was removed and amphotericin B was initiated. No response was obtained, and voriconazole was added to treatment. Despite of an afebrile and culture-negative period, the patient died as a result of Acinetobacter sepsis and multiorgan failure. Minimal inhibitory concentration values for both of the Saprochete strains were found as 0.25 µg/ml for amfoterisin B, 1 µg/ml for flukonazol, 0.125 µg/ml for vorikonazol and 0.25 µg/ml for itrakonazol. Virulence model was created by injecting the isolates to the Galleria mellonella larvae, and the life cycle of the larvae were determined. The observation revealed that the infected larvae began to die on the second day and there was no live larvae remained on the eleventh day.

Visceral phaeohyphomycosis caused by Alternaria alternata offering a diagnostic as well as a therapeutic challenge.
Phaeohyphomycosis is a heterogeneous group of opportunistic infections caused by dematiaceous molds, which are distributed worldwide as plant pathogens but rarely cause human diseases. However, due to the growing populations of immunocompromised patients, these fungi are frequently recognized as important human pathogens. We are reporting this very rare, unique case for the first time from Islamabad, Pakistan, describing the association of visceral Phaeohyphomycosis caused by the opportunistic fungus Alternaria alternata, affecting the left kidney, with the immunocompromised state in a young incidentally detected patient with insulin-dependent type I diabetes. The case was diagnosed on the basis of a high index of clinical suspicion, microbial cultures, microscopy, imaging studies and endourological procedures. The patient did not respond well to the highly sensitive Amphotericin B, resulting in loss of the kidney. Therefore, we suggest that clinicians involved in treating immunocompromised patients should have a high degree of clinical suspicion for such opportunistic pathogens to allow timely initiation of the correct diagnostic and therapeutic work-up.

Trichosporon inkin as an Emergent Pathogen in Patients With Severe Pemphigus.
To our knowledge, these are the first reports of bloodstream infections by Trichosporon inkin in patients with pemphigus.. Trichosporon inkin, a novel organism causing bloodstream infection, was detected in 2 patients with pemphigus. An elderly man with pemphigus foliaceus died despite treatment with liposomal amphotericin B, 3 mg/kg/d, and a young girl with pemphigus vulgaris responded to treatment with voriconazole, 8 mg/kg/d, for 24 days. One of the T inkin isolates had a minimal inhibitory concentration of 2 mg/L against amphotericin B, suggesting resistance to the drug.. Delayed suspicion of invasive infection by T inkin may result in a poor outcome in patients with severe forms of pemphigus. This opportunistic infection is highly refractory to conventional potent antifungal treatment.

Antifungal susceptibility and phenotypic characterization of oral isolates of a black fungus from a nasopharyngeal carcinoma patient under radiotherapy.
During a research project on fungal Candida species in patients wearing obturator treated with radiotherapy for their recurrent nasopharyngeal carcinoma, we serendipitously observed the presence of black fungus in two consecutive samples from a patient.. The samples were collected from a 57 year-old Hong Kong gentleman who diagnosed to have undifferentiated type of nasopharyngeal carcinoma. He was treated with definitive concurrent chemoradiotherapy followed by adjuvant chemotherapy and then received a second-course radiotherapy with IMRT. 18S rDNA sequencing revealed that the isolates belong to Exophiala dermatitidis which was susceptible to fluconazole, itraconazole, ketoconazole and voriconazole. Interestingly, E. dermatitidis isolates were resistant to caspofungin and one isolate was resistant to amphotericin B. Both isolates formed biofilms comparable to that of Candida albicans. Single isolate of E. dermatitidis showed hemolysin and proteinase ability comparable to C. albicans whilst the other isolate was not.. We, for the first time, reported the discovery of a black fungus-E. dermatitidis isolates derived from a patient with nasopharyngeal carcinoma treated with radiotherapy. These isolates were shown to be resistant to caspofungin, a major antifungal agent for systemic candidiasis. As little is known about the black fungus in the clinical setting, it is important that clinicians must keep abreast of the new discovery in this field.

A rare case of urinary tract infection due to Trichosporon asahii in a diabetic patient.
Trichosporon asahii is a basidiomycete yeast responsible for white piedra and onychomycosis in the immunocompetent host. In the immunocompromised patients, invasive infections are reported; their diagnosis is difficult and they are associated with high mortality rate. Urinary infection due to Trichosporon Asahi is rare but its incidence increasing. We report the case of a 58 year old diabetic patient. The yeast was isolated from urine samples of three consecutive crops in pure form. The patient improved after antifungal therapy.

A Hemophagocytic Lymphohistiocytosis Case with Newly Defined UNC13D (c.175G>C; p.Ala59Pro) Mutation and a Rare Complication.
Hemophagocytic lymphohistiocytosis (HLH) represents a severe hyperinflammatory condition with cardinal symptoms of prolonged fever, cytopenias, hepatosplenomegaly, and hemophagocytosis by activated, morphologically benign macrophages with impaired function of natural killer cells and cytotoxic T lymphocytes. A 2-month-old girl, who was admitted with fever, was diagnosed with HLH and her genetic examination revealed a newly defined mutation in the UNC13D (c.175G>C; p.Ala59Pro) gene. She was treated with dexamethasone, etoposide, and intrathecal methotrexate. During the second week of treatment, after three doses of etoposide, it was noticed that there was a necrotic plaque lesion on the soft palate. Pathologic examination of debrided material in PAS and Grocott staining revealed lots of septated hyphae, which was consistent with aspergillosis infection. Etoposide was stopped and amphotericin B treatment was given for six weeks. HLH 2004 protocol was completed to eight weeks with cyclosporine A orally. There was no patient with invasive aspergillosis infection as severe as causing palate and nasal septum perforation during HLH therapy. In immunocompromised patients, fungal infections may cause nasal septum perforation and treatment could be achieved by antifungal therapy and debridement of necrotic tissue.. Hemofagositik lenfohistiositoz (HLH) uzamış ateş, sitopeni, hepatosplenomegali semptomları ile seyreden, active olmuş, morfolojik olarak benign makrofaj ve doğal öldürücü hücreler ile sitotosik T lenfosit fonksiyon bozukluğu sonucu gelişen hiperenflamatuvar bir durumdur. İki aylık düşmeyen ateş yakınması ile başvuran hasta HLH tanısı aldı ve hastanın genetik incelemesinde UNC13D (c.175G>C; p.Ala59Pro) geninde yeni tanımlanan bir mutasyon saptandı. Hastaya deksamatazon, etopozit ve intratekal metotreksat tedavileri başlandı. Tedavinin 2. haftasında, üç doz etopozit aldıktan sonra, yumuşak damakta plak lezyonu fark edildi ve bu nekrotik lezyon debride edildi. Debridman materyalinin patolojik incelemesinin PAS, Grocott boyamasında aspergilloz enfeksiyonu ile uyumlu olarak çok sayıda septalı hif görüldü. Etopozid tedavisi sonlandırılarak altı hafta boyunca amphotericin B tedavisi verildi. HLH 2004 tedavi protokolü oral siklosporin ile sekiz haftaya tamamlandı. HLH tedavisi sırasında yumuşak damak perforasyonuna neden olacak kadar ağır aspergilloz enfeksiyonu geçiren bir olgu bildirilmemiştir.

NOCARDIA BEIJINGENSIS PSOAS ABSCESS AND SUBCUTANEOUS PHAEOHYPHOMYCOSIS CAUSED BY PHAEOACREMONIUM PARASITICUM IN A RENAL TRANSPLANT RECIPIENT: THE FIRST CASE REPORT IN THAILAND.
We describe the first case of a psoas muscle abscess caused by Nocardia beijingensis and subcutaneous phaeohyphomycosis caused by Phaeoacremonium parasiticum in a renal transplant recipient. The patient was treated for nocardiosis with percutaneous drainage and intravenous trimethoprim/sulfamethoxazole (TMP/SMX) combined with imipenem for 2 weeks, followed by a 4-week course of intravenous TMP/SMX and then oral TMP/SMX. During hospitalization for the psoas muscle abscess the patient developed cellulitis with subcutaneous nodules of his right leg. Skin biopsy and cultures revealed a dematiaceous mold, subsequently identified as P. parasiticum by DNA sequencing. The subcutaneous phaeohyphomycosis was treated with surgical drainage and liposomal amphotericin B for 4 weeks followed by a combination of itraconazole and terbinafine. The patient gradually improved and was discharged home after 18 weeks of hospitalization.

Skin nodules in a patient with acute lymphoblastic leukaemia.
Opportunistic infections cause a significant morbidity and mortality in immunocompromised patients. We describe the case of a patient with skin fusariosis and a probable cerebral toxoplasmosis after UCB stem cell transplantation for B-cell acute lymphoblastic leukaemia. Fusarium species (spp) infections are difficult to treat. To date, there has been no consensus on the treatment of fusariosis and the management of its side effects. Given the negative pretransplant Toxoplasma serology in this case, identifying the origin of the Toxoplasma infection was challenging. All usual transmission routes were screened for and ruled out. The patient's positive outcome was not consistent with that of the literature reporting 60% mortality due to each infection.

Phaeohyphomycosis fungal infections in solid organ transplant recipients: clinical presentation, pathology, and treatment.
Dematiaceous, or dark-pigmented, fungi are known to cause infections such as phaeohyphomycosis, chromoblastomycosis, and mycetoma. These fungi are becoming increasingly important opportunistic pathogens in solid organ transplant recipients (SOTR). We present a retrospective chart review of 27 SOTR who developed phaeohyphomycosis infections post transplant from 1988 to 2009.. Cases were reviewed for fungal species isolated, date and source of culture, immunosuppressive and fungal therapy used, and outcome. The majority of isolates obtained were from the skin and soft tissue, with 3 pulmonary and brain abscesses.. The time from transplantation to onset of infection ranged from 2 months to 11 years. The species isolated were Exophiala (11), Ochroconis (3), Alternaria (2), Phoma (2), Wangiella (1), Cladosporium (1), Aureobasidium (1), Chaetomium (1), Coniothyrium (1), and non-sporulating fungi (2). An additional 4 patients had infections confirmed by pathology, but no cultures were done. Most of the affected skin lesions were surgically debrided and treated with itraconazole; 2 patients were treated with voriconazole and 2 with amphotericin D. Death from fungal disease occurred only in patients with pulmonary and brain abscesses.. As the number of SOTR increases, so does the incidence of fungal infections in that population. Surgery, along with antifungal therapy and a reduction in immunosuppression, are the cornerstones of treatment.

[Cutaneous mucormycosis caused by Rhizopus microsporus].
Mucormycosis are rare fungal infections occurring chiefly in the lung or the rhinocerebral compartment, particularly in patients with immunodeficiency or mellitus diabetes. We report the case of an elderly patient with cutaneous mucormycosis caused by Rhizopus microsporus.. An 89-year-old man presented a skin lesion of the forearm rapidly becoming inflammatory and necrotic. The patient had been treated for 2months with oral corticosteroids for idiopathic thrombocytopenia. Histological and mycological examination of the skin biopsy revealed the presence of a filamentous fungus, R. microsporus. The outcome was unfavorable, despite prescription of high-dose liposomal amphotericin B.. Mucormycosis are infrequent opportunistic infections caused by angio-invasive fungi belonging to the Mucorales order. Cutaneous presentations are rare, and in rare cases the species R. microsporus is isolated in clinical samples. Diagnosis is based on histological examination highlighting the characteristic mycelium within infected tissue, together with ex vivo mycological identification using morphological and molecular methods. Treatment consists of liposomal amphotericin B combined with debridement surgery.. R. microsporus is a marginal fungal species rarely isolated in clinical practice, and even less in dermatology departments. This clinical case report highlights the severity of infection with this fungus, particularly in the absence of early surgery.

[Hemoptysis complicating bronchopulmonary mucormycosis in a diabetic patient].
Mucormycosis are the fungal infections caused by emerging ubiquitous filamentous fungi classified as zygometes and order as mucorales. They occur mainly in immunosuppressed patients and diabetics. The onset of hemoptysis, in this context, may rapidly become life-threatening.. We report the case of a man of 83 years, Caribbean with a history of non-insulindependent diabetes and HTLV1 seropositive. At admission he presented with fever, cough and cachexia. Chest X-ray revealed a snapshot of excavation within alveolar consolidation. Endoscopy showed a mucopurulent plug obstructing lingula. The histological appearance of bronchial biopsies was in favor of mucormycosis. A combined treatment with liposomal amphotericin B and posaconasole was implemented, but the occurrence of abundant hemoptysis led us to make a left upper lobectomy. Finally, the outcome was favorable and the patient was discharged after hospitalization of 56 days..

Focus on invasive mucormycosis in paediatric haematology oncology patients: a series of 11 cases.
Mucormycosis has emerged as an increasingly important infection in oncology centres with high mortality, especially in severely immunocompromised patients. We carried out a retrospective study of 11 children with mucormycosis treated in seven French oncology-haematology paediatric wards during the period from 1991 to 2011. Lichtheimia corymbifera and Mucor spp. were the predominant pathogens. Treatment regimens included antifungal therapy, reversal of underlying predisposing risk factors and surgical debridement. Although mucormycosis is associated with high mortality, this infection could be cured in eight of our cases of severely immunocompromised paediatric cancer patients. Topics: Adolescent; Amphotericin B; Antineoplastic Agents; Child; Female; Hospitals, Pediatric; Humans; Immunocompromised Host; Leukemia, Myeloid, Acute; Lung Diseases, Fungal; Male; Mucor; Mucormycosis; Neutropenia; Opportunistic Infections; Retrospective Studies; Risk Factors; Young Adult | 2013 |
Oral infections caused by yeasts in patients with head and neck cancer undergoing radiotherapy. Identification of the yeasts and evaluation of their antifungal susceptibility.
Yeasts occur as part of the normal human microbiota. Nevertheless, some species are opportunistic, affecting immunocompromised patients such as those undergoing oncologic treatment.. To detect the presence of yeasts in patients suffering from head and neck cancer who are receiving radiation therapy and display lesions in the oral cavity, compatible with candidiasis; and to evaluate the antifungal susceptibility of the isolates recovered.. Sixty samples from patients were obtained by swabbing the oral mucosa. Identification of isolates were performed by classical taxonomic, morphological and biochemical methods as well as by using commercial identification kits. Susceptibility to antifungal drugs was determined by the agar diffusion method with Neosensitabs(®) disks.. Forty-six samples (77%) yielded positive findings, and species recovered were: Candida albicans (22 isolates), Candida tropicalis (13 isolates), Candida parapsilosis (six strains), Candida krusei (three strains), Candida dubliniensis and Saccharomyces cerevisiae (one each). All strains were susceptible to itraconazole, clotrimazole, voriconazole, nystatin and amphotericin B. On the other hand, 65% of strains were miconazole-susceptible while 35%, showed intermediate susceptibility. With regard to ketoconazole, only three strains (7%) corresponding to C. albicans (one isolate) and C. krusei (two isolates) displayed intermediate susceptibility. Only C. krusei strains were resistant to fluconazole while all the other species were susceptible. Eventually, only six isolates (13%) were susceptible to terbinafine while the remaining strains were resistant in vitro.. Early detection of etiological agents causing lesions, as well as the evaluation of their susceptibility to commonly used drugs, are crucial in order to choose the appropriate treatment that will minimize complications while improving the quality of patients' lives.

T cell non-Hodgkin's lymphoma with colesional mucormycosis presenting as palatal perforation: a case report.
Non-Hodgkin's lymphoma (NHL) is predominantly a disease of lymph nodes, but extranodal involvement is not very uncommon. Palatal involvement by NHL is rare. Mucormycosis is a devastating fungal infection commonly seen in immunocompromised individuals, including those with NHL, but it is affecting the same region has been reported very rarely. Simultaneous infiltration of hard palate by NHL and mucormycosis is extremely unusual. Herein we describe a patient who presented with palatal hole with histopathological examination revealing presence of lymphoma with colesional mucormycosis. The identification of mucor was vital because chemotherapy alone in the absence of antifungals would have had devastating consequences as the mortality of untreated mucormycosis is high.

Successful treatment of rhino-orbital mucormycosis by a new combination therapy with liposomal amphotericin B and micafungin.
Mucormycosis is a rapidly progressive fungal infection that usually occurs in patients with diabetes mellitus or in immunocompromised patients. Sinus involvement is the most common clinical presentation and the rates of mortality increase with the orbital extension. The treatment of mucormycosis includes aggressive surgical debridement and systemic antifungal therapy. Early diagnosis and prompt initiation of effective antifungal drugs are essential for successful outcome. However, the role of orbital exenteration for the case of orbital involvement remains controversial, and the drugs effective against mucormycosis are limited. We present a successfully treated case with rhino-orbital mucormycosis caused by Rhizopus oryzae in a diabetic and dialysis patient. The early diagnosis, surgical debridement and a new combination therapy with liposomal amphotericin B and micafungin were effective. This new combination antifungal therapy will be useful for the treatment of mucormycosis.

Rhinocerebral mucormycosis--a case report.
Rhinocerebral mucormycosis (RCM) is a rare, fulminating opportunistic fungal infection caused by a fungus of order Mucorales. These fungi are ubiquitus, subsisting on decaying vegetation and diverse organic material. Although fungi and spores of Mucorales show minimal intrinsic pathogenicity towards normal person, they can initiate aggressive and fulminating infection in immunocompromised host. Since RCM occurs infrequently, it may pose a diagnostic and therapeutic dilemma for those who are not familiar with its clinical presentation.. We present a patient with classical presentation of RCM involving paranasal sinuses, orbit, and cranial base who was treated by combination of aggressive surgical and medical therapy.. The purpose of this paper is to draw attention to the clinical presentation and pathogenesis of RCM and to emphasize need for high index of suspicion in diagnosis and treatment.

How I treat cryptococcosis in organ transplant recipients.
Cryptococcosis is a significant opportunistic mycoses in organ transplant recipients. Topical developments in the field in the past few years have highlighted important issues and at the same time raised new questions regarding the management of this yeast. These include, for example, management of pretransplant cryptococcosis during transplant candidacy and timing of transplant in these instances; potential for donor transmission of cryptococcosis in light of recent fatal transmissions; and prevention and treatment of Cryptococcus-associated immune reconstitution syndrome. Discussed herein are challenges posed by these issues and evidence-based data to optimize the management of posttransplant cryptococcosis.

[Subcutaneous infection spread by Scytalidium (Neoscytalidium) dimidiatum].
S. dimidiatum (recently reclassified as N. dimidiatum) is a fungus that causes nail and/or superficial skin infection. It may also cause subcutaneous and deep infection, chiefly in immunocompromised patients.. An 87-year-old male treated with oral corticosteroids for sarcoidosis consulted for violaceous cutaneous nodules on the back of his hands. Histopathological examination revealed epithelioid cell granulomas with numerous mycelial filaments and multiple spores. Culture of a biopsy sample resulted in growth of numerous colonies of S. dimidiatum and the patient was treated with intravenous amphotericin B.. This organism is transmitted by direct or indirect contact with contaminated soil or plants. It mainly causes superficial skin and nail infections, and may result in deeper infections on rare occasions. We report a case of subcutaneous infection with S. dimidiatum in an immunocompromised patient (due to general steroid therapy) that was successfully treated using amphotericin B.

Invasive aspergillosis in pediatric oncology patients: a rare event with poor prognosis--case analysis to plan better targeted prophylactic or therapeutic measurement.
Despite the implementation of new antifungal drugs, invasive aspergillosis (IA) still remains a considerable challenge in pediatric oncology with a severe mortality. Prophylactic and therapeutic measurement have to be evaluated in these rare but poor prognostic patients. Therefore the entire group of patients at risk of developing IA has to be defined before cooperative prospective trials. In a retrospective analysis including all our patients with malignancies we looked for patients with proven/probable IA. Cases of the period from 2003 to 2008 were analyzed in detail.In the period between 2003 to 2008 24 of 755 patients were affected by proven/ probable IA. Compared to former studies incidence increased from 1.3%in 1980 to 3.4% in 2008. AML patients with or without allogeneic/haploidentical stem cell transplantation were at highest risk (24% and 25% respectively, in comparison to 1% in ALL-patients). Survival after 2 years was 50% for patients with AML and IA. In patients with high risk to develop IA the effect of intensified, intravenous antimycotic prophylaxis has to be proven prospectively in a cooperative and randomized setting.

Gastrointestinal mucormycosis--four cases with different risk factors, involving different anatomical sites.
Mucormycosis of the gastrointestinal tract is a rare infection that usually occurs in patients who are immunocompromised and carries a high mortality. We report four cases of gastrointestinal mucormycosis seen over a one year period with different presentations, risk factors and different anatomical sites of involvement. A preoperative diagnosis was made only in one patient. All underwent surgery, three survived and one died postoperatively from multiorgan failure.

Two rare cases of central nervous system opportunistic mycoses.
This article presents two cases of opportunistic mycoses (OMs) of the central nervous system (CNS) caused by Cryptococcus neoformans and Aspergillus nidulans, respectively. The patients were hospitalised in local hospitals between 2009 and 2011 because of unspecific symptoms (fever, headache, and/or weight lost). Duration of symptoms varied from 4 days to over 2 weeks. The patients were treated with antibiotics and symptomatically. OM was not suspected in any of them. The patients became critically ill with symptoms of CNS involvement and were transferred to the Intensive Care Unit (ICU) of the University Hospital for Infectious diseases (UHID) in Zagreb. None of the patients belonged to the high-risk population for developing OMs. They were not HIV-infected, had no transplantation of bone marrow or solid organ, and were not on severe immunosuppressive chemotherapy. Fungi were isolated from cerebrospinal fluid (CSF) samples and, in one patient, from aspirate of cerebral abscess. Isolation and mycological identification of all fungal isolates and in vitro antifungal susceptibility testing of these isolates were done at the Reference Centre for Mycological Diagnostics of Systemic and Disseminated Infections (RCMDSDI) in Zagreb. The patient with cryptococcal meningitis was treated with amphotericin B and fluconazole and the patient with cerebral aspergilloma with voriconazole.

Sequential opportunistic infections in two German Shepherd dogs.
Two German Shepherd dogs with sequential opportunistic infections are described. The first was a 2-year-old male with cryptococcal rhinitis that spread to involve the optic nerves and brain. It was successfully treated with combination therapy utilising amphotericin B administered for 2 years, but the dog developed a disseminated Aspergillus deflectus infection 5 years later and was euthanased. The second case was a 4-year-old male that presented for a severe, deep-seated infection of the right antebrachium, with gradual extension to contiguous tissues. Neosartorya fischeri (anamorph; Aspergillus fischerianus) was isolated in pure culture and detected in histological sections. The infection was refractory to itraconazole, but resolved after amputation of the affected limb. Five months later, the dog developed a localised cutaneous lesion on the proximal pelvic limb, from which Pythium insidiosum was isolated and then visualised in tissue sections, together with a structure thought to be grass seed. This lesion was treated by wide surgical resection, although it was reported that the dog died of disseminated disease some months later. These cases provide further circumstantial evidence that young adult German Shepherd dogs have a predilection to developing invasive infections with fungi and other saprophytic pathogens.

Disseminated nocardiosis masking an atypical zygomycosis presentation in a kidney transplant recipient.
Immunosuppressive agents increase the vulnerability of solid organ transplant patients to opportunistic infections. An atypical clinical presentation of a bacterial and fungal co-infection makes diagnosis and treatment even more challenging in this population. A 54-year-old hypertensive woman underwent a cadaveric kidney transplant after years on hemodialysis. Her treatment included mycophenolate, tacrolimus, and prednisone. By post-transplant week 8, she had pneumonia followed by progressive visual changes and seizures. Diagnostic work-up, consisting of magnetic resonance imaging of the brain and chest x-ray, showed several cerebral ring-enhancing lesions, and a pulmonary cavitary lesion. Disseminated nocardiosis was suspected and therapy was started. Skin biopsy was taken from a nodular lesion and culture confirmed Nocardia species infection. During hospitalization, neurological deficit persisted with worsening of brain lesions. She underwent excision of a brain abscess and the final pathologic report showed mucormycosis, revealing the patient's co-infection by 2 different pathogens. After therapy with liposomal amphotericin B and posaconazole, she has remained stable for more than 1 year. Disseminated nocardiosis masked and delayed the diagnosis and treatment of a more aggressive and worrisome organism. Mucormycosis, as a non-fatal isolated brain abscess without rhinal involvement, is an atypical presentation, and only a few cases have been reported.

[Association of post-transplant lymphoproliferative disease and visceral leishmaniasis after kidney transplantation].
Malignancies and opportunistic infections are frequently observed after solid-organ transplantation. Their occurrence strongly affects recipient survival. We report the case of a 29-year-old Tunisian kidney-recipient who was diagnosed simultaneously with post-transplant lymphoproliferative disease (PTLD) and visceral leishmaniasis (VL). Withdrawal of immunosuppressive therapy together with antiparasitic treatment using liposomal amphotericin B, and anti-CD20 antibodies medication resulted in cure of leishmaniasis and remission from PTLD. This case is of clinical interest because of the uncommon association of VL with PTLD after solid organ transplantation. It is also original by the favourable outcome of VL and PTLD, both known as life-threatening diseases. Also, it illustrates the predisposing role of immunosuppressive therapy in occurrence of opportunistic infections and malignancies after solid organ transplantation.

[Fungal infections in children with malignant disease].
Intensified chemotherapy and hematopoietic stem cell transplantation result in severe and prolonged granulocytopenia with an increased risk of invasive fungal infections. The major fungal species that cause serious infections in cancer patients are Candida species and Aspergillus species. The main features of Candida infection in this context are oropharyngeal candidiasis and Candida esophagitis, chronic disseminated candidiasis, also known as hepatosplenic candidiasis, and candidemia. Aspergillus can cause severe lung infection but also sinusal or CNS infection. Because invasive fungal infections are severe and often life-threatening, preventive and empirical managements have become standard practice. An increasing number of antifungal drugs is now available, notably lipid formulations of amphotericin B (liposomal amphotericin B), new azoles with broad spectrum of activity and echinocandin.

Roles of calcineurin and Crz1 in antifungal susceptibility and virulence of Candida glabrata.
A Candida glabrata calcineurin mutant exhibited increased susceptibility to both azole antifungal and cell wall-damaging agents and was also attenuated in virulence. Although a mutant lacking the downstream transcription factor Crz1 displayed a cell wall-associated phenotype intermediate to that of the calcineurin mutant and was modestly attenuated in virulence, it did not show increased azole susceptibility. These results suggest that calcineurin regulates both Crz1-dependent and -independent pathways depending on the type of stress.

Successful triple combination therapy of disseminated absidia corymbifera infection in an adolescent with osteosarcoma.
Mucormycosis are opportunistic infections mostly observed in immunocompromised patients. We report the case of a 13-year-old girl who suffered a systemic mucormycosis without presenting the usual risk factors. She was undergoing antineoplastic chemotherapy for advanced osteosarcoma of the femur with an uncommunicative pathologic fracture and pulmonary metastasis. Absidia corymbifera was isolated from skin lesions at the primary tumor site. She subsequently developed fungal pulmonary localizations and blood vessel thrombosis. Surgical treatment together with systemic, high doses of liposomal amphotericin B, posaconazole, and caspofungin cured the local infection and controlled systemic lesions. Unfortunately, the break in chemotherapy led to pulmonary metastasis progression.

An unusual case of granulomatous lymphadenitis due to Prototheca zopfii var. portoricensis in an immunocompetent man in China.
Protothecosis is an uncommon human infection caused by Prototheca. Prototheca spp can be considered as saprophytes, and in spite of their frequency in the environment, they are of low virulence and may cause chronic infection with low-grade inflammation in humans. At present, only three species are recognized: Prototheca wickerhamii, Prototheca zopfii and Prototheca stagnora. Of these, the former two have been associated with human disease. This study was an investigation of the clinical and microbiological features of a case of granulomatous lymphadenitis due to P. zopfii var. portoricensis in an immunocompetent man in China.. We report the case of a 39-year-old male, who presented with swollen lymph nodes, from which the organism was isolated and identified by the RapidID Yeast Plus test (Remel, Santa Fe, NM, USA) and PCR molecular analysis. The pathogenicity of the isolate was confirmed in a mouse model and antifungal drug susceptibility testing was carried out.. The pathogen was identified as Prototheca zopfii. The DNA sequence of the 18S SSU rDNA regions of the isolate strain were 100% (1205/1205) identical with Prototheca zopfii var. portoricensis. Antifungal susceptibility tests revealed that it was sensitive to amphotericin B, but resistant to 5-flucytosine, fluconazole, ketoconazole, and itraconazole. The patient responded to treatment with intravenous itraconazole and amphotericin B.. Based on the patient's symptoms and microscopic evaluation, cultures, and molecular analyses of the isolate, granulomatous lymphadenitis due to P. zopfii var. portoricensis was diagnosed. P. zopfii var. portoricensis as a causative agent of human lymphadenitis in an immunocompetent case has not been reported, though a few cases of protothecosis have been reported in China. The real number of protothecosis cases may be greater than that reported in the literature. Thus, clinicians should be vigilant for any unknown cause of granulomatous lymphadenitis and should undertake an intensive histopathology, mycology examination, and even molecular analysis to rule out or confirm a potential Prototheca infection.

Renal allograft recipient with co-existing BK virus nephropathy and pulmonary histoplasmosis: report of a case.
Renal allograft recipients are prone to opportunistic infections, rarely multiple coexisting infections, due to the immunocompromised state. To the best of our knowledge, no case of a co-existing polyoma virus nephropathy and pulmonary histoplasmosis in a renal allograft recipient has been reported so far in the available literature. A 55-year-old male renal allograft recipient underwent graft biopsy for asymptomatic graft dysfunction. The graft biopsy showed features of polyoma virus nephropathy. Soon after, he developed fever with pulmonary nodules. Fine-needle aspiration from lung nodules showed intracellular yeast forms of histoplasma. The patient responded well to amphotericin B with subsidence of fever. The co-existence of renal allograft-limited infection like polyoma virus and systemic fungal infection such as histoplasmosis should be kept in mind in a transplant recipient with graft dysfunction and non-specific systemic symptoms. Prompt recognition of these infections permits the clinician to institute appropriate therapeutic modification and improved survival.

Sinonasal mucormycosis: case report.
To present and discuss the case of a diabetic patient admitted with acidoketotic coma, with inner canthus tumefaction due to mucormycosis.. A 38-year-old diabetic man was admitted with acidoketotic coma and poor general health status. Clinical examination found right inner canthus tumefaction and mucopurulent rhinorrhea. Endoscopy of the nasal fossae found medial meatus sphaceluses. Sinus CT scan found a bilateral ethmoid infiltrating and osteolytic infectious process. Emergency endoscopic bilateral ethmoidectomy was performed. Mucormycosis was diagnosed, and liposomal amphotericin B was administered intravenously for 1 month then replaced by posaconazole. The patient was followed up monthly; the antifungal treatment was terminated after 8 months, the disease appearing to have resolved.. Mucormycosis is one of the most rapidly fatal fungal infections. Facial and cerebral CT scan is essential and is systematically abnormal in case of sinonasal mucormycosis. Emergency multidisciplinary treatment should address the diabetes and include rapid surgical debridement and effective antifungal medication. The reference antifungal is amphotericin B, to be administered at maximal dose (3 to 5 mg/kg per day). Posaconazole, available in Europe since July 2005, proved successful in the present case.

Lichtheimia corymbifera subcutaneous infection successfully treated with amphotericin B, early debridement, and vacuum-assisted closure.
Lichtheimia corymbifera (syn. Absidia corymbifera, Mycocladus corymbifer) is an ubiquitous cosmopolitan mold that can cause primary cutaneous and deep tissue infection in healthy individuals. We report a subcutaneous L. corymbifera infection in a 13-year-old immune-competent child, with a severe traumatic injury, with a successful outcome after early diagnosis and treatment with lipid amphotericin B, early debridement, and vacuum-assisted closure (VAC).

Delayed and overlooked diagnosis of an unusual opportunistic infection in a renal transplant recipient: visceral leishmaniasis.
Visceral leishmaniasis is a rare opportunistic infection in renal transplantation patients and its presentation may be associated with or masked by many other factors in immunosuppressed patients. So, if it is not searched for in particular, diagnosis may be easily overlooked or delayed in renal transplant patients. A 32-year-old renal transplant recipient devoleped splenomegaly, pyrexia and pancytopenia. Six months after the first bone marrow examination, the delayed diagnosis was made possible by a second bone marrow aspiration. Liposomal amphotericin B was effective in his treatment although he had a recurrence. Early diagnosis of visceral leishmaniasis is crucial for the renal transplant recipient's therapy; and even in treated patients, the mortality rate may be high. In our case, although the time up to diagnosis was as long as six months after the onset of symptoms, response to treatment was satisfactory with higher doses of liposomal amphotericin B in the second cycle. Also, in the short term, the rate of recurrence was comparable to other reported patients who were diagnosed and treated in a month.

In vitro activities of isavuconazole against opportunistic filamentous and dimorphic fungi.
The in vitro activity of isavuconazole was compared to those of amphotericin B, fluconazole, itraconazole, voriconazole, posaconazole, and ravuconazole against 300 clinical isolates of Pseudallescheria boydii, Paecilomyces lilacinus, Fusarium spp., Bipolaris spicifera, Curvularia lunata, Alternaria alternata, Exophiala spp., Rhizopus arrhizus, Mucor circillenoides, Absidia corymbifera, Blastomyces dermatitidis, Histoplasma capsulatum and Coccidioides posadasii. MICs were determined by a broth macrodilution method based on the CLSI M38-A procedure. The triazoles were relatively uniform in that they showed strong in vitro inhibitory activity against most of the tested fungi. In vitro activity was variable with strains of P. lilacinus while with Fusarium spp., the triazoles were found to have limited in vitro activity and amphotericin B was moderately active. The results suggest that isavuconazole is a broad-spectrum antifungal agent, effective against a wide range of moulds in vitro.

Cryptococcus neoformans fatal sepsis in a chronic lymphocytic leukemia patient treated with alemtuzumab: case report and review of the literature.
Cryptococcosis is a disseminated fungal disease typically associated with immunosuppression and characterized by high mortality rates. Cryptococcus neoformans has been reported to be isolated from blood cultures in around 20% of patients with cryptococcosis, and cryptococcemia has been correlated with poor prognosis. We report a case of fatal C. neoformans fungemia in a neutropenic patient with a history of chronic lymphocytic leukemia treated with alemtuzumab. The patient presented with loss of consciousness and died after 5 days of antifungal therapy with liposomal amphotericin B. The international literature regarding opportunistic infections after immunosuppressive therapy with alemtuzumab with particular attention on fungal infections has also been reviewed.

[Non-fatal disseminated mucormycosis in a solid organ transplant].
Mucormycosis is a rare fungal infection occurring most frequently in immunocompromised patients. The pathogens are filamentous fungi, order of Mucorales. Disseminated mucormycosis is a severe, life treating disease. Early diagnosis is a major determinant for prognosis, however, it remains difficult. The management consists in an early antifungal therapy using lipid formulation of amphotericin B associated with an extensive surgical debridement. Despite this therapeutic of choice, the mortality of disseminated mucormycosis remains high.. We report the case of disseminated mucormycosis in a 25 years old woman 9 months after a pulmonary transplantation. The clinical presentation included pulmonary and thyroid localization and the pathogen was Absidia corymbifera. The patient survived thanks to a large surgical debridement, and an early antifungal bitherapy by lipid formulation of amphotericin B and posaconazole.. The re-emergence and the high mortality of mucormycosis in solid organ transplant receiver show the necessity to find new therapeutic approaches. Posaconazole associated with liposomal amphotericin B could be an interesting option to treat disseminated mucormycosis and improve their outcome.

Activities of antifungal agents against yeasts and filamentous fungi: assessment according to the methodology of the European Committee on Antimicrobial Susceptibility Testing.
We compared the activities of antifungal agents against a wide range of yeasts and filamentous fungi. The methodology of the European Committee on Antimicrobial Susceptibility Testing (EUCAST) for yeasts and spore-forming molds was applied; and a total of 349 clinical isolates of Candida spp., other yeast species, Aspergillus spp., and nondermatophyte non-Aspergillus spp. were investigated. The average geometric mean (GM) of the MICs of the various drugs for Candida spp. were as follows: amphotericin B (AMB), 0.55 microg/ml; liposomal amphotericin B (l-AMB); 0.35 microg/ml; itraconazole (ITC), 0.56 microg/ml; voriconazole (VRC), 0.45 microg/ml; posaconazole (POS), 0.44 microg/ml; and caspofungin (CPF), 0.45 microg/ml. The data indicated that the majority of Candida spp. were susceptible to the traditional and new antifungal drugs. For Aspergillus spp., the average GM MICs of AMB, l-AMB, ITC, VRC, POS, and CPF were 1.49 microg/ml, 1.44 microg/ml, 0.65 microg/ml, 0.34 microg/ml, 0.25 microg/ml, and 0.32 microg/ml, respectively. For the various zygomycetes, the average GM MICs of AMB, l-AMB, ITC, and POS were 1.36 microg/ml, 1.42 microg/ml, 4.37 microg/ml, and 1.65 microg/ml, respectively. Other yeastlike fungi and molds displayed various patterns of susceptibility. In general, the minimal fungicidal concentrations were 1 to 3 dilutions higher than the corresponding MICs. POS, AMB, and l-AMB showed activities against a broader range of fungi than ITC, VRC, and CPF did. Emerging pathogens such as Saccharomyces cerevisiae and Fusarium solani were not killed by any drug. In summary, the EUCAST data showed that the in vitro susceptibilities of yeasts and filamentous fungi are variable, that susceptibility occurs among and within various genera and species, and that susceptibility depends on the antifungal drug tested. AMB, l-AMB, and POS were active against the majority of pathogens, including species that cause rare and difficult-to-treat infections.

Molecular identification and susceptibility testing of Trichosporon isolates from a Brazilian hospital.
In this study the molecular identification and susceptibility profile of 21 clinical isolates, from a Brazilian hospital, belongs to six different species of Trichosporon were described. Trichosporon asahii was the predominant species and corresponded to 43% of isolates. Eighty three percent of the strains isolated from deep sites were identified as T. asahii, while only 17% belong to a non-T. asahii species (Trichosporon inkin). In general, the MICs were high and independent of the species of Trichosporon as well as the clinical origin of strain. Amphotericin B and fluconazole were less effective against Trichosporon spp. and high MIC values of voriconazole, posaconazole and ravuconazole were observed. Fifty-six percent (5/9) of T. asahii strains were isolated from deep sites, whereas 8% (1/12) of non-T. asahii species were isolated from those sites. A total of 89% of T. asahii isolates exhibited resistance to amphotericin B in vitro.

Palatal zygomycosis: experience of 21 cases.
To present a clinical report of palatal zygomycosis, its epidemiological, mycological features, and our treatment experience.. Retrospective report.. This is a 25-year long retrospective trial of clinically and mycologically proven cases of zygomycosis. Some patients underwent a biopsy of the palatal lesion and autopsy. This study reports the treatment experience with amphotericin B alone and in combination with itraconazole and fluconazole.. Twenty-one cases (18.75%) of zygomycosis with palatal involvement were included in the study, from a total of 112 cases screened. Mean age was 36.5 years, with 18 adults and three children. The associated pre-disposing factors were: ketoacidotic diabetes (five type-1 and 15 type-2), and acute leukaemia in one patient. The clinical varieties were as follows: 19 cases of rhinocerebral (RC) involvement and two disseminated cases. Palatal ulcers occurred in 3/21 early cases (14.3%) and in 16/21 cases after the nasal involvement. All patients received amphotericin B; in four patients, it was combined with itraconazole and four with fluconazole. Clinical and mycological cure was achieved in 4/21 patients (19.04%).. Zygomycosis with palatal involvement occurs in around 18% of cases, usually associated with RC modalities; it has an acute and generally lethal course.

Successful treatment of mucormycosis in a renal allograft recipient.
Mucormycosis is a rare but potentially lethal fungal infection in renal allograft recipients with rhinocerebral mucormycosis is the most common presentation. The usual infection route is inhalation of the spores, but certain procedures such as intravenous cannulation and bladder catheterization are often the cause of infection.. A 50-year-old female dermatologist received an allograft from an emotionally related living donor, 24-year-old male with the same blood group and 3/6 mismatches. After severe attack of acute vascular rejection associated with rupture graft, that was managed properly she developed rinocereral mucormycosis. It was diagnosed early and aggressively treated with amphoteracin B and carefully monitored with favourable graft and patient survival. Up to our knowledge, this is the first case of renal transplant with extrarenal-ethemoidal sinus-mucor infection associated with acute vascular rejection that in spite of aggressive anti-rejection therapies with methylprednisolone, rituximab and plasma exchange, had favourable outcome in terms of graft and patient survival.. Mucormycosis in a renal allograft recipient is an extremely rare and potentially lethal complication. Aggressive anti-rejection therapy is a risk factor for the development of this unfavourable outcome. Early diagnosis, aggressive treatment with amphoteracin B and careful monitoring can be helpful in treating these patients and achieve favourable prognosis.

Sarcoidosis as risk factor for cryptococcal meningitis in an apparently immunocompetent patient.
Cryptoccus neoformans meningitis (CNM) is an opportunistic infection that typically occurs in immunosuppressed patients. Subjects affected by sarcoidosis, a systemic granulomatous disease of unknown cause, are predisposed to CNM because of the impairment of cell-mediated immunity and because of the chronic corticosteroid therapy they frequently receive. Here we report the case of a 38-year-old man who developed CNM as the first clinical manifestation of sarcoidosis. The patient developed CNM even though he was apparently immunocompetent and was not on therapy with either corticosteroid or cytotoxic drugs.

Clinical presentations and outcomes of Penicillium marneffei infections: a series from 1994 to 2004.
To describe the clinical presentation, management, and outcomes of patients with Penicillium marneffei infections in a regional hospital in Hong Kong.. Retrospective study.. A regional and tertiary human immunodeficiency virus-referral hospital in Hong Kong.. Those who had penicilliosis during the inclusive period January 1994 to February 2004.. Forty-seven immunocompromised patients (44 being human immunodeficiency virus-positive) with penicilliosis were retrospectively studied. Fever, malaise, and anaemia were the commonest presentations. Most diagnoses were obtained from blood cultures (83%) and lymph node biopsies (34%). Five (11%) died, death being attributable to penicilliosis; four (9%) of them had received no specific antifungal treatment due to late presentation and late diagnosis. The CD4 count of human immunodeficiency virus-infected patients upon diagnosis of penicilliosis was low (median, 20.0 cells/mm3). Most (70%) patients received amphotericin B as an induction treatment, followed by oral itraconazole, although a smaller proportion (21%) received oral itraconazole only. All surviving human immunodeficiency virus-infected patients took highly active antiretroviral treatment and oral itraconazole as secondary prophylaxis after treatment of penicilliosis. The prognosis appeared satisfactory with early diagnosis and administration of appropriate antifungal therapy. Relapse ensued in two (4%) of the patients only.. Penicillium marneffei infection in immunocompromised patients is a serious disease with significant mortality if not diagnosed early and treated with appropriate antifungal drugs. Simple investigations like blood culture enable the diagnosis in the majority of cases. Immunocompromised patients who have been successfully treated should receive oral itraconazole as a maintenance therapy to prevent relapse.

Cryptococcal meningitis in patients with glioma: a report of two cases.
We describe two patients with high-grade glioma undergoing treatment with corticosteroids and chemotherapy who presented with cryptococcal meningitis and sepsis. This report of two cases highlights the importance of examining the efficacy of prophylactic antibiotic and/or antifungal regimens in this patient population due to their increased risk of opportunistic infections.. A 73-year-old man with a history of glioblastoma multiforme (GBM), on dexamethasone and status post radiation therapy and two cycles of temozolamide, presented with decreased level of consciousness for 24 h and was found to have cerebrospinal fluid (CSF) and blood cultures positive for Cryptococcus neoformans. A 33-year-old man with a history of anaplastic astrocytoma, on dexamethasone and status post radiation therapy, four cycles of temozolomide and two cycles of Lomustine (CCNU), presented with headache, dizziness and photophobia and was found to have CSF and blood cultures positive for Cryptococcus neoformans.. Both patients were treated with an initial regimen of amphotericin B and flucytosine for a minimum of two weeks and switched to fluconazole for 6 months to 1 year of treatment.. Patients with high-grade glioma treated with long-term corticosteroid therapy and chemotherapy are at increased risk of developing opportunistic infections. The two patients reported here developed cryptococcal meningitis and sepsis. Prophylactic regimens with either fluconazole or itraconazole currently exist that effectively decrease the incidence of both cryptococcal infections. Further investigations into the risk:benefit ratio of primary prophylactic therapy in this patient population may prove beneficial.

Lysosome and HER3 (ErbB3) selective anticancer agent kahalalide F: semisynthetic modifications and antifungal lead-exploration studies.
Kahalalide F (1) shows remarkable antitumor activity against different carcinomas and has recently completed phase I clinical trials and is being evaluated in phase II clinical studies. The antifungal activity of this molecule has not been thoroughly investigated. In this report, we focused on acetylation and oxidation of the secondary alcohol of threonine, as well as reductive alkylation of the primary amine of ornithine, and each product was evaluated for improvements in antifungal activity. 1 and analogues do not exhibit antimalarial, antileishmania, or antibacterial activity; however, the antifungal activity against different strains of fungi was particularly significant. This series of compounds was highly active against Fusarium spp., which represents an opportunistic infection in humans and plants. The in vitro cytotoxicity for the new analogues of 1 was evaluated in the NCI 60 cell panel. Analogue 5 exhibited enhanced potency in several human cancer cell lines relative to 1.

Risk factors for pulmonary Aspergillus terreus infection in patients with positive culture for filamentous fungi.
Invasive aspergillosis (IA) is a common fungal infection in immunocompromised patients and has a high mortality rate. Among patients with IA, Aspergillus terreus infections have become a growing concern in the past few years.. To determine the clinical risk factors for isolation of and respiratory infection by A terreus in patients with culture findings positive for filamentous fungi.. Cohort study of 505 consecutive isolates of filamentous fungi in 332 patients from one center. A terreus was present in 46 isolates from 40 patients (9.1%). Clinical histories were reviewed to identify the risk factors related to isolation of and infection by A terreus, which were grouped into three categories (ie, host factors, factors related to immunosuppression, and factors related to hospitalization), and were analyzed using a multiple logistic regression model.. A total of 192 of 505 isolates studied (38%) were due to invasive respiratory infection. A total of 27 of 46 cultures (58.7%) that were positive for A terreus were due to invasive infection (odds ratio [OR], 2.53; 95% confidence interval [CI], 1.37 to 4.69; p = 0.034). The factors associated with invasive A terreus infection were prophylactic use of amphotericin B aerosols (OR, 27.8; 95% CI, 6.7 to 109.7; p = 0.001) and mechanical ventilation (OR, 3.3; 95% CI, 1.02 to 10.9; p = 0.04). Transplantation was associated with a lower risk of A terreus infection (OR, 0.2; 95% CI, 0.046 to 0.789; p = 0.02).. In patients with culture findings positive for filamentous fungi, the prophylactic use of amphotericin B aerosols and mechanical ventilation are associated with a higher risk of A terreus infections. In these patients, transplantation is associated with a lower risk of isolation and respiratory infection by A terreus.

[Primary cutaneous aspergillosis in a leukemic child].
Primary cutaneous aspergillosis is a rare cutaneous disease that usually affects immunodepressed patients of any age. The most common associated disorders in children are leukemias and lymphomas although it can also occur in neonates and preterms due to their intrinsic immunological immaturity. We report the case of a 4-year-old boy diagnosed of acute lymphoblastic leukemia that, during chemotherapy, developed an ulceronecrotic inflammatory cutaneous lesion in the venopuncture area of the left forearm, and whose microbiological culture was positive for Aspergillus flavus.

Cost-effectiveness analysis of antifungal treatment for patients on chemotherapy.
Invasive fungal infections are fatal complications for patients on chemotherapy, and antifungal prophylactic treatment has been commonly recommended. Because its clinical and economic impact is not well known, we evaluated cost-effectiveness of anti-fungal treatment for patients who were neutropoenic as a result of chemotherapy. We constructed a hypothetical cohort of 40-year-old patients with acute myelogenic leukemia to evaluate years of life survived (YLS), costs (US$), and incremental cost-effectiveness ratio (US$/YLS). The following treatment strategies for fungal infections were compared: (1) prophylactic fluconazole strategy: oral fluconazole administration concurrently with chemotherapy; (2) empirical amphotericin B strategy: empirical intravenous amphotericin B administration at the point where fever is detected; and (3) no prophylaxis strategy: intravenous micafangin administration at the point where fungal infections is diagnosed. Baseline analyses showed that prophylactic fluconazole strategy involved higher costs but also longer YLSs (25,900 US$ and 24.08 YLS). The incremental cost-effectiveness ratio of prophylactic fluconazole strategy was 625 US$/YLS compared to no prophylaxis strategy, and 652 US$/YLS compared to empirical amphotericin B strategy. Baseline result was found to be robust through sensitivity analyses. Our study showed that concurrent administration of oral fluconazole during induction chemotherapy appears to ensure clinical benefits together with acceptable cost-effectiveness.

Successful treatment of Trichosporon mucoides infection with lipid complex amphotericin B and 5-fluorocytosine.
Infections in immunocompromised children can stem from bacteria, fungi, viruses, or protozoa, but most importantly, from the host's endogenous bacterial flora. Disseminated infection caused by Trichosporon species is one of the emerging mycoses in neutropenic patients, particularly when they are treated for haematological malignancy with cytotoxic and immunosuppressive chemotherapy. We report a 15-year-old boy with acute lymphoblastic leukaemia, whose Trichosporon mucoides infection was successfully treated with lipid complex amphotericin B plus 5-fluorocytosine.

Antifungal susceptibility of Cryptococcus neoformans to amphotericin B and fluconazole.
Cryptococcus neoformans has emerged as an important opportunistic fungal pathogen in immunocompromised individuals. The therapeutic options of C. neoformans an opportunistic fungal pathogen include flucytosine, amphotericin B, and azole agents. However in the present scenario, emergence of resistance has been reported, hence this study was undertaken to evaluate antifungal susceptibility pattern of C. neoformans isolates from this southern part of India. Ten isolates of C. neoformans were tested against Amp B and fluconazole, of which 7 were susceptible to both and a single isolate of C. neoformans var gatti was resistant to both with MIC of 32mg/ml and 64mg/ml respectively.

Reactivation of dormant cutaneous Leishmania infection in a kidney transplant patient.
Leishmaniasis is an infection caused by a protozoan parasite belonging to genus Leishmania and transmitted by the Phlebotomus sandfly. Clinical presentations of infection include visceral, cutaneous, and mucocutaneous forms. Leishmaniasis is endemic in Africa, Asia, Europe, South America, and southern part of North America. This infection is extremely rare in the US and is mostly found among travelers coming from endemic areas. Cases of cutaneous and visceral leishmaniasis have been reported in organ transplant recipients in endemic areas.. We describe a case of cutaneous leishmaniasis in a kidney transplant patient, originally from Bolivia, who resides in the area known to be non-endemic for leishmaniasis and who is known not to travel within or outside of the US after the transplantation.. Histologic examination of cutaneous lesion revealed extensive subcutaneous lymphohistiocytic inflammation with clusters of amastigote within histiocytes.. To our knowledge, this is the first case of cutaneous leishmaniasis in a kidney transplant patient residing in the US in an area known to be non-endemic for leishmaniasis, probably after reactivation of a previously dormant infection acquired outside of the US at least 9 months prior to developing clinical symptoms.

Acremonium pyomyositis in a pediatric patient with acute leukemia.
Invasive Acremonium infection in humans is rare. We report a patient with leukemia who developed pyomyositis due to Acremonium species. Painful cutaneous nodules and severe myalgia were the first clinical manifestations during the neutropenic stage after chemotherapy. Magnetic resonance image (MRI) revealed multiple nodular lesions scattered along the intramuscular regions of the lower legs. Culture of an aspiration grew Acremonium species. Surgical drainage was performed. Although all antifungal agents tested showed no in vitro inhibitory activity, we successfully treated this patient with amphotericin B, granulocyte colony-stimulating factor (G-CSF), and surgical drainage.

Rapidly advancing invasive endomyocardial aspergillosis.
The exposure to Aspergillus organisms/spores is likely common, but disease caused by tissue invasion with these fungi is uncommon and occurs primarily in the setting of immunosuppression. We report a case of rapidly advancing invasive endomyocardial aspergillosis secondary to prolonged usage of multiple broad-spectrum antibiotics in a nonimmunocompromised host. A 36-year-old cotton textile worker presented to our institution with a 3-month history of weight loss and fatigue. He reported receiving prolonged use of multiple broad-spectrum antibiotic treatment. The echocardiogram demonstrated multiple endomyocardial vegetations and a mass in the left atrium. Myocardial biopsy specimen revealed an invasive endomyocardial aspergillosis. The patient was investigated for immune deficiency including HIV, and this workup was negative. Treatment was started with amphotericin B and heparin for presumed left atrial thrombus. The patient died because of a rupture of mycotic aneurysm that resulted in cerebral hemorrhage. This case illustrates the risk of an invasive fungal infection in a nonimmunocompromised host who is a prolonged user of antibiotics in the setting of environmental exposure of opportunistic invasive fungal infections.

Salvage therapy with caspofungin for invasive aspergillosis: results from the caspofungin compassionate use study.
The objective was to prospectively assess the efficacy and safety of caspofungin as salvage therapy for invasive aspergillosis in patients enrolled in the caspofungin compassionate-use study.. Forty-eight patients with invasive Aspergillus infections (36 with pulmonary infection, 12 with extrapulmonary or disseminated infection) were enrolled in this study. All patients were refractory to or intolerant of intravenous amphotericin B or a lipid amphotericin formulation(s). Efficacy was assessed at end of intravenous caspofungin therapy based on the clinical (symptom/sign and radiographic) response.. Underlying diseases included hematological malignancy (69%), organ transplant (8%), and AIDS (6%). Forty-three (90%) patients were refractory to prior antifungal treatment, including 25 patients refractory to multiple agents. Sixteen (33%) were neutropenic at study entry. Following caspofungin therapy, a favorable response was noted in 44% (20/45) of the patients, including nine (20%) and 11 (24%) patients with complete and partial responses, respectively. Caspofungin was generally well tolerated one serious drug-related adverse event was reported.. In this study, caspofungin was an effective alternative for patients with refractory Aspergillus infections.

[Endogenous Candida endophthalmitis combined with severe general diseases].
Endogenous Candida endophthalmitis is a rare disease with increasing frequency and poor prognosis.. The course of endogenous Candida endophthalmitis in 7 eyes of 5 patients (age 2 months to 76 years) was evaluated. Underlying general diseases were diagnosed as colon cancer, diverticulitis, pancreatic insufficiency (with subclavian catheter), ileus and diabetes mellitus. Diagnosis was based on the very typical ocular feature combined with a positive blood or vitreous culture. Intensive antimycotic drug therapy was initiated and pars plana vitrectomy performed as soon as possible.. The delay between onset of ocular symptoms and diagnosis amounted to one week and 2 months. In 3 eyes of 2 patients no vitrectomy could be done because of the very impaired state of health. These patients died of their general diseases one week and 2 months, respectively, later. During follow-up (4 weeks to 51 months) three eyes reached visual acuity of 5/10, 4/10 and 1/10. One eye reached 1/20 after additional surgery because of retinal detachment. In all vitrectomized eyes the diagnosis was substantiated by a positive culture of vitreous fluid. No recurrence of ocular inflammation was observed.. Early vitrectomy seems to be mandatory in each case which is suspected of Candida endophthalmitis. Only with this option it is possible to fix the diagnosis and initiate adequate therapy in due time in order to improve the original poor prognosis.

Haemopoietic cell transplantation of patients with a history of deep or invasive fungal infection during prophylaxis with liposomal amphotericin B.
Relapse of a preceding fungal infection is a considerable risk during haemopoietic stem cell transplantation. The optimal secondary prophylaxis has not been found so far since the application of standard drugs is hampered by potential ineffectiveness or intolerable side effects. This investigation describes haemopoietic cell transplantation of patients with a history of invasive or systemic fungal infection (IFI). The strategy was either administration of liposomal amphotericin B as secondary prophylaxis or an early switch to liposomal amphotericin B after administration of azoles. The 43 patients had a history of proven (n = 14), probable (n = 14) and possible (n = 15) IFI. Twenty-eight patients (65%) could be discharged from the BMT ward without signs of mycosis. Transplant-related mortality was 35%. Overall, 12 fungus-related (IFI) deaths (28%) occurred. The percentage of fungus-related deaths was highest in the 'proven' group with 43% compared to 20 and 21% in the two other groups. Side effects of liposomal amphotericin B were low. A discontinuation of the drug was not necessary in any patient. Serum creatinine showed a slight increase to 128% (median) of the baseline allowing continuous administration of concomitant nephrotoxic drugs such as cyclosporin A. In conclusion, secondary prophylaxis with or early switch to liposomal amphotericin B facilitates allogeneic stem cell transplantation of patients with a history of IFI with minor side effects. However, fungal infections and transplant-related mortality remain major problems in this often heavily pretreated subgroup of patients.

Amphotericin B lipid complex in the management of invasive aspergillosis in immunocompromised patients.
The efficacy and renal safety of amphotericin B lipid complex (ABLC) were assessed in 398 patients with invasive aspergillosis. The most common underlying conditions were hematopoietic stem-cell transplantation (101/398 [25%]), hematologic malignancy (101/398 [25%]), and solid-organ transplantation (109/398 [27%]). The most common reason for administration of ABLC was lack of response to prior antifungal therapy. Overall, 65% of patients had a favorable clinical response: 44% were cured or improved, and 21% were stabilized. Clinical responses were similar for patients who received ABLC as either first-line or second-line therapy. One hundred forty-four patients whose results could be evaluated received ABLC concurrently with or after therapy with itraconazole. No antagonism was observed when therapy with ABLC followed therapy with itraconazole. Patients infected with Aspergillus terreus, an innately polyene-resistant species, experienced a 37% response rate. Changes in serum creatinine levels were not clinically significant in most patients; however, dialysis was initiated in 7 patients, of whom 6 had prior antifungal therapy or preexisting renal disease. Analysis of this large database demonstrated the efficacy and safety of ABLC in the treatment of invasive aspergillosis.

Treatment of non-Aspergillus moulds in immunocompromised patients, with amphotericin B lipid complex.
An assessment was made of the efficacy and renal safety of amphotericin B lipid complex (ABLC) in the treatment of patients with invasive fungal infections caused by moulds other than Aspergillus species, on the basis of a retrospective analysis of data from the Collaborative Exchange of Antifungal Research (CLEAR) database. Data from CLEAR for 64 patients with zygomycosis were published previously. The database was further queried and yielded results for 28 patients with fusariosis and 84 patients infected with other non-Aspergillus moulds. Of 26 patients with fusariosis whose results could be evaluated, 46% (n = 12) were cured or improved, and an additional 12% (n = 3) were stable. Of 79 patients infected with other non-Aspergillus moulds whose results could be evaluated, 61% (n = 48) were cured or improved, and an additional 15% (n = 12) were stable. In an area with little guidance for therapy, the CLEAR data indicate that ABLC can be an effective broad-spectrum treatment choice for several invasive and refractory non-Aspergillus mould infections.

Successful use of amphotericin B lipid complex in the treatment of cryptococcosis.
The efficacy and renal safety of amphotericin B lipid complex (ABLC) injection were assessed in 106 patients with cryptococcal infection. Eighty-three patients (78%) had a central nervous system (CNS) infection. Of these patients, 20 initiated azole therapy concomitantly with ABLC therapy, and 7 had received prior azole therapy, which continued during administration of ABLC. Clinical response (cured or improved) was achieved in 67 (66%) of 101 patients whose results could be evaluated. Response rates were 65% (51/78) for patients with a CNS infection and 70% (16/23) for patients without a CNS infection. The response rate for patients with HIV infection was 58% (30/52). Response rates were 56% (19/34) for patients who were refractory to prior antifungal therapy, 65% (11/17) for patients who were intolerant of prior antifungal therapy, 60% (3/5) for patients with underlying renal disease who received prior antifungal therapy, 76% (25/33) for patients with underlying renal disease who did not receive prior antifungal therapy, and 73% (8/11) for patients with no renal disease who did not receive prior antifungal therapy. A mean serum creatinine level decrease of 0.02 mg/dL occurred. ABLC was an effective treatment for cryptococcal infection in immunocompromised patients.

Risk stratification and targeted antifungal prophylaxis for prevention of aspergillosis and other invasive mold infections after liver transplantation.
Antifungal prophylaxis has been proposed for liver transplant recipients at increased risk for invasive mold infection. Risk factors for invasive mold infection after liver transplantation were selected to divide recipients into 3 groups: (1) high risk-transplantation on hemodialysis or delay of hospital discharge beyond day 7 after transplantation because of allograft or renal insufficiency; (2) intermediate risk-retransplantation or transplantation for fulminant hepatic failure; (3) low risk-absence of conditions in groups 1 and 2. During an intervention period (February 1999-April 2001), prophylactic administration of a lipid complex of amphotericin (Abelcet) at 5 mg/kg intravenously every 24 to 48 hours was recommended for high-risk recipients. The frequency of mold infection was compared to that of a preintervention period (February 1998-January 1999) when antifungal prophylaxis was not provided. During the intervention period, invasive mold infection developed in 2 (6%) of 35 high-risk recipients, 0 of 28 intermediate-risk recipients, and 1 (0.5%) of 187 low-risk recipients. Overall, of 58 liver transplant recipients, 3 (5%) developed an invasive mold infection during the preintervention period, compared with 3 (1%) of 250 during the intervention period (P = 0.08). The only death from invasive mold infection occurred during the preintervention period. Rates of pulse corticosteroid treatment of rejection and cytomegalovirus infection were lower during the intervention period. In conclusion, readily identifiable patient characteristics can be used to stratify liver transplant recipients for risk of invasive mold infection. Antifungal prophylaxis given to high-risk recipients may provide cost-effective prevention of these infections.

Lung infection due to opportunistic fungus, Phialemonium obovatum, in a bone marrow transplant recipient: an emerging infection with fungemia and Crohn disease-like involvement of the gastrointestinal tract.
We report the first case of Phialemonium obovatum fungemia with subsequent caseating granulomatas in the lung and Crohn disease-like involvement of the gastrointestinal tract in a bone marrow transplant recipient. This phaeoid fungus has been rarely described as an opportunistic infection in immunosuppressed patients. The patient was diagnosed with chronic myelogenous leukemia and underwent subsequent peripheral bone marrow transplant. After 6 months, he developed graft-versus-host disease of the skin and liver with fever and severe diarrhea. Fecal bacterial cultures and cytomegalovirus serologies were negative. Computed tomographic scan showed a peripheral pulmonary mass. A lung wedge biopsy of the lesion showed septate branching hyphae (4-5 microm in diameter) with terminal globular structures (10 microm in diameter). The hyphae were similar in width to that of an Aspergillus species but had a more moniliform appearance. Blood cultures grew a pure culture of P. obovatum. He was treated with amphotericin B and itraconazole for 6 months without remission of the diarrhea. Biopsies of the stomach, colon, and rectum showed granulomatous inflammation with marked crypt distortion simulating Crohn disease. In retrospect, the fungus was found to be resistant to both of the aforementioned drugs and susceptible to voriconazole and posaconazole. The gastrointestinal findings raise the possibility of further dissemination of a partially treated Phialemonium infection.

Effectiveness of amphotericin B lipid complex (ABLC) treatment in allogeneic hematopoietic cell transplant (HCT) recipients with invasive aspergillosis (IA).
A total of 85 allogeneic hematopoietic cell transplant (HCT) recipients with invasive aspergillosis treated with amphotericin B lipid complex (ABLC) were identified from the Collaborative Exchange of Antifungal Research (CLEAR) database. Of these patients, 78% (66/85) presented with pulmonary aspergillosis. Graft-versus-host disease (GVHD) was present in 24 of 85 patients. The response rate to ABLC was 31% (26/85) overall and 21% (5/24) in patients with GVHD. The overall response rate to first-line ABLC treatment was 41% (11/27). Four of nine (44%) patients with GVHD responded to first-line treatment with ABLC, while only one of 13 (8%) responded to ABLC as second-line therapy. Five of 18 (28%) and four of 14 (29%) patients, respectively, responded to sequential or concurrent treatment with ABLC and itraconazole. None of seven patients responded who continued receiving itraconazole after the start of ABLC therapy. At the end of ABLC therapy, serum creatinine had doubled in 12% of patients (10/85), and 2% (2/85) had developed a requirement for dialysis. These data suggest that ABLC, especially when administered as first-line therapy, can result in clinical response even in the most immunocompromised patients, that is, HCT recipients with GVHD, with minimal effects on renal function.

Epidemiology and outcome of infections due to Aspergillus terreus: 10-year single centre experience.
Aspergillus terreus, a less common pathogen, appears to be an emerging cause of infection at our institution, the Medical University Hospital of Innsbruck. Thus the epidemiology and outcome of A. terreus infections over the past 10 years was assessed. We analysed 67 cases of proven invasive aspergillosis (IA) according to the European Organisation for Research and Treatment of Cancer/Mycoses Study Group criteria, investigated antifungal susceptibility of amphotericin B (AMB), voriconazole and caspofungin and performed molecular typing of A. terreus. Patients with proven IA caused by A. terreus (n = 32) and non-A. terreus (n = 35) were evaluated. The two groups were comparable in terms of age, gender, underlying disease, antifungal prophylaxis and duration of neutropenia (P > 0.05). Leukaemia was the most common underlying malignancy. Fungal dissemination occurred in 63% of the patients. Aspergillus terreus infections were associated with a lower response rate to AMB therapy (20%), compared with 47% for patients with non-A. terreus infections (P < 0.05). In vitro, A. terreus was found to be resistant to AMB and molecular typing discriminated between patients isolates, showing a high strain diversity with 26 distinct types (I-XXVI) identified by combination of three primers. Aspergillus terreus infections displayed evidence of AMB resistance in vitro and in vivo and were associated with a high rate of dissemination and poor outcome; A. terreus causes systemic infections of endemic character in Tyrol, Austria. The onset of A. terreus infection depends not on the degree of immunosuppression but on environmental Aspergillus spp. exposure.

[Economic evaluation of the treatment of systemic fungal infections in immunocompromised patients: the role of itraconazole].
In recent years, the incidence of HIV infection, the intensity of chemotherapy regimens for cancer and the use of bone marrow transplantation have all increased. This results in an increase in the incidence of systemic fungal infections, which are associated high rates of morbidity and mortality in this immunosuppressed population; the incidence is growing: 50% for neutropenic/transplant bone marrow patients and 5-20% for organ transplant. Fluconazole, itraconazole, amphotericin-B and, in the recent years, caspofungin and voriconazole are the most frequently used antifungal agents. However, the newly developed formulations of itraconazole and lipid-associated formulations of amphotericin-B have provide new treatment options for systemic fungal infection and have prompted a number of comparisons of the treatment costs of empirical therapy. The i.v. formulation of itraconazole may be more cost effective than either conventional or liposomial formulations of amphotericin-B when used as empirical therapy for neutropenic patients with persistent fever despite broad spectrum antibiotic therapy, but further studies are required. The lack of studies, national and international, and the small amount of available data on the cost of systemic fungal infections mean that the costs saving from prophylactic and empirical use of antifungals are difficult to estimate.

Intracranial granuloma and skull osteolysis: complication of a primary cutaneous cryptococcosis in a kidney transplant recipient.
Cryptococcosis is the third most common invasive fungal infection in organ transplant recipients after candidiasis and aspergillosis. It occurs almost exclusively in the late posttransplantation period (>6 months after the initiation of immunosuppression). Subclinical onset of meningitis is the usual clinical presentation. Despite initiation of therapy, the mortality rate associated with this infection in this patient population remains high. To the best of our knowledge, this report describes one of the first cases of a rare entity: a primary cutaneous cryptococcosis in a renal transplant recipient disclosed by skull osteomyelitis and pseudotumoral intracranial extension. Surgical debridement and azole antifungal therapy were performed. Ten months after the onset of treatment, the patient feels good, clinical examination findings are normal, and no sign of evolutive cryptococcosis is noted.

Continuous infusion of amphotericin B: preliminary experience at Faculdade de Medicina da Fundação ABC.
Intravenous amphotericin B deoxycholate (AmB-D) infusions, usually given over 4 hours, frequently induce nephrotoxicity and undesirable infusion-related side effects such as rigors and chills. There is evidence in the literature that the use of AmB-D in the form of continuous 24-hour infusion is less toxic than the usual four-hour infusion of this drug. Our objective was to evaluate the efficacy and safety of continuous infusion of AmB-D for the treatment of persistent fever in neutropenic patients with hematological malignancies after chemotherapy.. Observational retrospective analysis of our experience with continuous infusion of AmB-D, at Faculdade de Medicina da Fundação ABC and Hospital Estadual Mário Covas in Santo André.. From October 2003 to May 2004, 12 patients with hematological malignancies and chemotherapy-induced neutropenia received 13 cycles of continuous infusion of AmB-D.. The median dose of AmB-D was 0.84 mg/kg/day (0.33 to 2.30 mg/kg/day). Concomitant use of nephrotoxic medications occurred in 92% of the cycles. Nephrotoxicity occurred in 30.76% of the cycles, hypokalemia in 16.67%, hepatotoxicity in 30% and adverse infusion-related events in 23%. All patients survived for at least seven days after starting continuous infusion of AmB-D, and clinical resolution occurred in 76% of the cycles.. Continuous infusion of AmB-D can be used in our Institution as an alternative to the more toxic four-hour infusion of AmB-D and possibly also as an alternative to the more expensive liposomal formulations of the drug.

Successful treatment of rhinocerebral zygomycosis with a combination of caspofungin and liposomal amphotericin B.
Genera of the order Mucorales (Rhizopus, Mucor, Rhizomucor, Absidia, Apophysomyces, Cunninghamella, and Saksenaea) cause an angioinvasive infection called zygomycosis. Mortality rates can approach 100% depending on the patient's underlying disease and form of zygomycosis. We report here on the unusual case of a patient with acute myelogenous leukemia and zygomycosis unresponsive to monotherapy with liposomal amphotericin B, who responded favorably following the addition of the echinocandin caspofungin acetate.

Successful elimination of an invasive Aspergillus nidulans lung infection by voriconazole after failure of a combination of caspofungin and liposomal amphotericin B in a boy with chronic granulomatous disease.
Chronic granulomatous disease is an inherited defect in host defense mechanisms mainly affecting neutrophil function. Pulmonary infection with Aspergillus nidulans in a child with chronic granulomatous disease could not be eliminated by a combination of caspofungin and liposomal amphotericin B. Voriconazole was successful in clearing the infection.

[Invasive infection by Aspergillus terreus treated successfully with liposomal amphotericin B].
A woman of 75 years old was admitted at our hospital for evaluation of worsening and weakness in inferior limbs. Several vertebral fractures by crushing, one doubtful discitis, an infiltrate with cavitation in the right superior lobe and one infiltrate in the left superior lobe were detected. In the biopsy of the consolidation a filamentous fungus was watched and in the bronchial washing specimen culture grew Aspergillus terreus. The infiltrates disappeared with liposomal Amphotericin B remaining with oral Itraconazol during three months more. The clinical and analytical data demonstrate the existence of a Overlap syndrome associate to antiphospholipid-antibody syndrome. We comment the peculiarity of the infection by Aspergillus terreus in patients who have not been in critical care and the good response at treatment with liposomal Amphotericin B. It contrasts with the high mortality referred in a recent review. Other aspects to comment are the coexistence with a collagen vascular and an antiphospholipid-antibody syndrome with the higher titles of IgM ACA that we have found in literature.

Aspergillosis of the central nervous system: a catastrophic opportunistic infection.
The clinical features and outcome of the treatment of aspergillosis of the central nervous system (CNS) in Thai patients are presented. The patients who were diagnosed as having CNS aspergillosis by tissue biopsy or culture from January 1, 1991 to December 31, 2000 were retrospectively reviewed. The study variables including age, sex, underlying disease, symptoms and signs, neuro-imaging studies, pathological findings and outcome of treatment, are described. There were seven cases of aspergillosis of the central nervous system. Four patients were male. The median age was 65 years (range 36-78 years). The most common underlying disease was diabetes mellitus (4/7; 57.1%). Two patients (28.6%) had no underlying disease. The most common primary site of infection was the paranasal sinuses (6/7; 85.7%). The most common clinical presentation was headache (6/7; 85.7%). Common neurological signs included multiple cranial nerve palsies (5/7; 71.4%) and alteration of consciousness (3/7; 42.9%). The median duration of the symptoms prior to admission was 60 days (range 8-180 days). All patients were treated with intravenous antifungal agents at high doses. Extensive surgery was performed in 6 patients. The mortality rate was very high (6/7; 85.7%). The median time from diagnosis and treatment to death was 53 days (22-720 days). Aspergillosis of the CNS should be considered in those with clinical features of headache, multiple cranial nerve palsies and alteration of consciousness accompanied by sinusitis, especially in elderly and diabetic patients. It remains a catastrophic opportunistic infection in spite of the current intensive and aggressive treatment.

Aspergillus terreus: an emerging amphotericin B-resistant opportunistic mold in patients with hematologic malignancies.
Invasive aspergillosis (IA) has emerged as a common cause of morbidity and mortality among immunocompromised patients. At The University of Texas M. D. Anderson Cancer Center (Houston, TX), Aspergillus terreus is second to A. fumigatus as the most common cause of IA. In the current study, the authors compared the risk factors and outcomes associated with IA caused by A. terreus and IA caused by A. fumigatus.. The authors retrospectively reviewed the medical records of 300 patients who received care at our institution between 1995 and 2001 and who had cultures that were positive for Aspergillus infection, including 90 patients whose cultures were positive for A. fumigatus and 70 patients whose cultures were positive for A. terreus.. Thirty-two patients with IA caused by A. terreus and 33 patients with IA caused by A. fumigatus were evaluated. The two groups were comparable in terms of age, gender, and underlying disease. Leukemia was the most common underlying malignancy (84%). More than 40% of patients in each group had undergone bone marrow transplantation. There was a trend toward a higher frequency of neutropenia among patients with IA caused by A. terreus (P = 0.12). IA caused by A. terreus was considered to be nosocomial in origin significantly more frequently compared with IA caused by A. fumigatus (P = 0.03). In vitro, A. terreus was found to be more resistant to amphotericin B (minimal inhibitory concentration [MIC90], 4.0 microg/mL) than to antifungal therapy (MIC90, 1.0 Hg/mL) in the isolates that were tested (< 50% of all isolates). The overall rate of response to antifungal therapy was 39% for patients with A. fumigatus infection, compared with 28% for patients with A. terreus infection (P = 0.43).. Despite the decreased in vitro susceptibility of A. terreus (relative to A. fumigatus) to amphotericin B, the two groups within the current patient population had comparably poor responses to amphotericin B preparation and somewhat improved responses to posaconazole.

A survey of anti-fungal management in lung transplantation.
Fungal infections are an important complication of lung transplantation, but no controlled studies of their management have been performed. Knowledge of actual anti-fungal strategies may aid in the design of future prospective studies.. Thirty-seven of 69 active lung transplant centers, accounting for 66% of all US lung transplantations, responded to our survey. The survey focused on fungal surveillance, pre- and post-transplant prophylaxis, and approach to fungal colonization.. The median number of lung transplantations performed by the centers in 1999 was 14 per year (range, 1-52), and median time that centers were in in operation was 9 years (range, 2-15 years). Seventy percent of centers had a transplant infectious diseases specialist. Pre-transplant fungal surveillance was performed by 81% of centers, with 67% of these surveying all patients and the remainder surveying only sub-sets of patients. Seventy-two percent of all centers started anti-fungal treatment if Aspergillus spp were isolated before transplantation. Itraconazole was the preferred agent (86%). After transplantation, 76% of centers gave anti-fungal prophylaxis, although 24% of these did so only in selected patients. Prophylactic agents in order of preference were inhaled amphotericin B (61%), itraconazole (46%), parenteral amphotericin formulations (25%), and fluconazole (21%); many centers used more than 1 agent. Prophylaxis was initiated within 24 hours by 71% and within 1 week by all centers. Median duration of prophylaxis was 3 months (range, <1 month-lifetime). All 37 centers used anti-fungal therapy if colonization with Aspergillus spp was detected for a median duration of 4.5 months. Itraconazole was the preferred agent. Only 59% of centers treated patients colonized with Candida spp. In a statistical analysis, centers with larger volumes were less likely to treat pre-transplant colonization with Candida spp but more likely to use agents other than itraconazole for post-transplant colonization with Aspergillus spp. Only 14% of centers engaged in any anti-fungal research at the time of the survey.. The majority of surveyed lung transplant programs actively manage fungal infection with prophylaxis or pre-emptive therapy, despite the absence of controlled trials. This survey may provide an impetus and a basis for designing prospective studies.

Pseudomembranous tracheobronchial aspergillosis: a rare manifestation of invasive aspergillosis in a non-neutropenic patient with Hodgkin's disease.
Pseudomembranous tracheobronchial aspergillosis coincident with systemic pulmonary aspergillosis represents a rare manifestation of fungal infection in immunocompromized hosts. We report on a patient with recurrent Hodgkin's disease, showing this infectious pattern after treatment with corticosteroids within the antineoplastic schedule, whereas neutropenia--the main risk factor for mold infections--had not occurred. An impaired number of helper T lymphocytes was merely detected as an additional, but hypothetical risk factor, when investigating the status of immunosuppression. Treated systemically with amphotericin B, the patient recovered quickly, although reported mortality rates are disastrous. What is crucial for the clinical management is an early diagnosis by bronchoscopy and cultural proof of the pathogen followed by an adequate antifungal treatment.

Aspergillus infection in lung transplant recipients with cystic fibrosis: risk factors and outcomes comparison to other types of transplant recipients.
To characterize Aspergillus infections in lung transplant recipients with cystic fibrosis (CF).. A retrospective analysis of 32 consecutive lung transplant recipients with CF who underwent bilateral lung transplant at the University of Wisconsin from 1994 to 2000 to determine the incidence, risk factors, and consequences of Aspergillus infection. The findings were compared to 101 non-CF recipients of lung transplants (93) and heart-lung transplants (8) for other transplant indications.. A university hospital.. Lung transplant recipients with CF or other indications for transplantation.. None.. Seventeen of 32 CF recipients (53%) had Aspergillus fumigatus isolated from their respiratory secretions prior to undergoing transplantation. Ten of these 17 (59%) recipients had A fumigatus persistently found in their respiratory secretions posttransplant vs 6 of 15 CF patients (40%) who had not been colonized pretransplant and 28 of 101 of the non-CF recipients (28%). Four of the preoperatively colonized CF recipients developed tracheobronchial aspergillosis (TBA) just distal to the bronchial anastomoses, and one recipient had dehiscence of the involved anastomosis. None of the CF recipients developed disseminated aspergillosis or pneumonia. Prophylactic antifungal therapy did not prevent TBA, and IV amphotericin B therapy was required to clear the infection in all four patients, with endobronchial debridement of necrotic tissue required in two of them. In contrast, 10 of the non-CF (10%) recipients developed Aspergillus infections posttransplant (TBA, 4 recipients; pneumonitis, 6 recipients), and only 3 patients had successful treatment and long-term survival (TBA, 2 patients; pneumonia, 1 patient). Donor lung ischemia time, cytomegalovirus infection or pneumonia, or pretransplant mechanical ventilation did not increase the risk of developing TBA in CF recipients.. The risk of TBA for patients receiving lung transplants for CF warrants early surveillance bronchoscopy to detect TBA, particularly in recipients with pretransplant colonization.

Continuous infusion of escalated doses of amphotericin B deoxycholate: an open-label observational study.
Amphotericin B deoxycholate (AmB-d) remains a mainstay of antifungal therapy for immunocompromised patients, despite being associated with significant therapy-related toxicity. Because continuous infusion of AmB-d is better tolerated than traditional administration over 2-6 hours, we evaluated escalation of the AmB-d dose in 33 patients (31 of whom were neutropenic), for whom the initial dosage of AmB-d (1 mg/kg/day) was gradually increased to 2.0 mg/kg/day when renal function remained stable and the drug was tolerated. Dose escalation was possible without delay in 28 patients. Median duration of AmB-d therapy was 16 days (range, 7-72 days). Infusion-related reactions accompanied <18% of AmB-d infusions. Twenty-seven patients had a decrease in creatinine clearance while receiving AmB-d therapy. A >2-fold decrease in creatine clearance was observed in 5 patients, and the decrease was dose-limiting in only 1 patient; no dialysis was required. In conclusion, continuous infusion of AmB-d escalated to 2.0 mg/kg/day seems not to cause additional impairment of vital organ functions and to be well tolerated by most patients.

Disseminated infection due to Scedosporium apiospermum in a patient with acute myelogenous leukemia.
A 62-year-old man diagnosed with acute myelogenous leukemia which had developed from myelodysplastic syndrome received cytarabine and idarubicine as an induction therapy. The patient developed pneumonia and bacterial sepsis during profound neutropenia. Fever and sepsis improved by using many anti-bacterials and anti-fungals but he became febrile again and complained of severe lumbar pain. 67Ga scintigram showed abnormal uptake in the lumbar vertebra and left sternoclavicular joint, suggesting a diagnosis of discitis and osteomyelitis in the lumbar vertebra and sternoclavicular arthritis. We biopsied the site several times but culture of the biopsy specimen could not isolate any pathogens, and high fever persisted for about 10 months despite administration of various anti-bacterials and anti-fungals. Finally we inserted a catheter into the abscess at the iliopsoas muscle and Scedosporium apiospermum was isolated in the bloody pus obtained from the catheter. Itraconazole and amphotericin B were restarted, and the high fever and lumbar pain improved rapidly. The findings of S. apiospermum infection in this patient emphasizes the importance of being aware of this pathogen in patients with hematologic malignancy during the neutropenic phase.

[Nosocomial urinary infection due to Trichosporon asahii. First two cases in Chile].
We present two cases of nosocomial urinary tract infection due to Trichosporon asahii in intensive care unit patients with bladder catheter from two hospitals in Santiago, Chile. Both patients had an several catheters and bacterial infections that required the use of antibiotic therapy. One strain showed in vitro resistance to amphotericin B. Both strains were susceptible to fluconazole, but presented MIC with dose-dependent susceptibility to ketoconazole and itraconazole. This is the first report showing T. asahii as urinary tract infection agent in Chile.

Combination therapy with caspofungin and liposomal amphotericin B for invasive aspergillosis.
Ina 24-month-old girl with acute lymphoblastic leukemia and invasive aspergillosis, only combination therapy with liposomal amphotericin B and caspofungin achieved a good response. Combination therapy could be a useful treatment option in children with invasive fungal disease, but before it can be routinely recommended, carefully controlled in vivo studies and well-designed randomized clinical trials are needed.

Voriconazole treatment of presumptive disseminated Aspergillus infection in a child with acute leukemia.
Invasive fungal infection continues to pose a significant threat to immunocompromised patients. The authors describe a pediatric patient receiving chemotherapy for acute undifferentiated leukemia who developed presumptive Aspergillus species infection disseminated to lung, liver, spleen, and bone. The authors report the successful treatment of this infection with the addition of voriconazole, a triazole antimycotic, to treatment with amphotericin and surgical debridement, in the setting of ongoing intensive chemotherapy.

Breakthrough trichosporonosis in a bone marrow transplant recipient receiving caspofungin acetate.
We report a case of invasive trichosporonosis due to Trichosporon beigelii originating in the left wrist of a bone marrow transplant recipient who was receiving caspofungin acetate as prophylaxis against invasive Aspergillus infection. While the patient's neutrophil count was recovering, treatment with fluconazole and amphotericin B lipid complex resulted in a complete clinical response.

Candida arthritis in a patient with chronic myelogenous leukemia (CML) in blastic transformation, unresponsive to fluconazole, but treated effectively with liposomal amphotericin B.
Candida arthritis is quite rare and might be caused either by direct intra-articular inoculation of Candida or secondary to hematogeneous seeding of Candida in immunocompromised hosts. Until now less than 50 cases of Candida arthritis have been reported in the literature. We report a case of Candida arthritis, which occurred in a patient with chronic myelogenous leukemia (CML) in blastic transformation. Aggressive chemotherapy and broad-spectrum antibiotics for a prolonged period for febrile neutropenia had been given to the patient. Arthritis of the left knee appeared during the recovery phase of leukopenia. Despite treatment with fluconazole, no clinical or microbiological improvement was obtained. Thus, administration of liposomal amphotericin B was started and after 3 days there was improvement. We can conclude that fluconazole might not be sufficient in some Candida arthritis cases and liposomal amphotericin B might be a good alternative in these resistant cases.

Filamentous fungi infection in patients with myelodysplastic syndrome. A report of twelve cases.
In this report we analyse the risk factors, the clinical characteristics and outcome of patients with myelodysplastic syndrome (MDS) who developed an Invasive Fungi Infection (IFI). This was a multicentric study involving 14 Italian Haematological Divisions during a 10-year period whose object was to identify the characteristics of patients with this infection. The study recorded 391 consecutive documented IFI, 12 of which (3%) occurred in MDS patients, from 5 of the participating centres. The primary localization of infection was lung in 10 cases and skin and paranasal sinus in 1 case each. Ten patients died at the end of follow up. The death was mainly attributable to IFI progression in nine of them. The factors that appeared related to an unfavourable outcome were intensive chemotherapy within 30 days before IFI diagnosis, presence of multiple localization at chest X-ray in patients with isolated pulmonary IFI and multiple sites of infection.

Invasive pulmonary aspergillosis: effects of early resection in a neutropenic rat model.
Invasive pulmonary aspergillosis is frequent in neutropenic patients. Usually localized in the beginning, the disease spreads and mortality is high despite antifungal treatment. The role of early adjuvant surgery is not clear. Surgery may help to confirm fungal disease, may control fungal disease locally and may prevent systemic spreading. This study examines effects of early resection on survival and dissemination in a rat model of localized invasive pulmonary aspergillosis.. Forty persistently neutropenic male albino rats were challenged with standardized conidial aspergillus inoculum injected into peripheral lung tissue of the right upper lobe under direct vision. Animals were divided into four groups. Twenty animals were treated with amphotericin B at 1 mg/kg per day beginning 48 h after inoculation, 20 animals were left untreated. In each group half the animals underwent early resection of localized invasive aspergillosis by lobectomy. Animals were checked daily and mortality was recorded up to 28 days after which surviving animals were sacrificed.. Significantly higher survival was observed in resected animals in the non-Am B groups (survival: 10 +/- 19% without early resection and 50 +/- 32% with early resection; P = 0.044). However, early resection did not lead to improved survival in animals treated with amphotericin B (survival 70 +/- 29% without early resection and 50 +/- 32% with early resection; P = 0.316).. In this rat model of localized invasive pulmonary aspergillosis effects of early resection on survival could be demonstrated only in animals not receiving amphotericin B treatment.

Cryptococcal infection in sarcoidosis.
A 48-year-old man with a history of sarcoidosis was transferred to the Mayo Clinic for evaluation and management of progressive neurologic decline. Two years before admission, he was admitted to a local hospital with mental status changes accompanied by ataxia and severe headache. A diagnosis of pulmonary and central nervous system sarcoidosis was made based on computed tomography of the head, lumbar puncture, and chest radiography. A mediastinoscopy with lymph node biopsy exhibited noncaseating granulomas and negative stains for microorganisms. Prednisone therapy was initiated at 80 mg/day. Clinical improvement was apparent for 13 months during steroid therapy until the slow taper reached a dosage of 20 mg/day. At that time, the patient was readmitted to the local hospital with severe confusion and skin lesions. When intravenous methylprednisolone therapy for presumed central nervous system sarcoidosis did not improve the patient's mental status, he was transferred to the Mayo Clinic. Physical examination of the thighs revealed large, well-marginated, indurated, irregularly bordered, violaceous plaques and rare, umbilicated, satellite papules with central hemorrhagic crusts (Fig. 1A). Superficially ulcerated plaques with a similar appearance to the thigh lesions were coalescing around the lower legs (Fig. 1B). A skin biopsy specimen of the thigh demonstrated abundant numbers of encapsulated organisms and minimal inflammatory response (Fig. 2). Skin, blood, and cerebrospinal fluid cultures confirmed the presence of Cryptococcus neoformans. Amphotericin and flucytosine combination therapy was initiated, and steroid dosages were gradually tapered. A test for human immunodeficiency virus was negative. The patient was dismissed from hospital after a complicated 2-month course resulting in improved mental status but progression of the lower extremity ulcerations as a result of polymicrobial infection.

Comparison of in vitro antifungal activities of amphotericin B lipid complex with itraconazole against 708 clinical yeast isolates and opportunistic moulds determined by National Committee for Clinical Laboratory Standards methods M27-A and M38-P.
We compared the in vitro antifungal activity of amphotericin B lipid complex (ABLC) with that of itraconazole (ITZ) against 535 yeast strains and 173 opportunistic filamentous fungi by using a microdilution method (National Committee for Clinical Laboratory Standards M27-A and M38-P). The overall geometric mean MIC was 0.13 microg/ml and 0.177 microg/ml for ITZ and ABLC, respectively, and the MIC(50) was 0.125 microg/ml for both agents against yeast isolates. ITZ had a similar or slightly superior efficacy compared to ABLC when tested against Candida albicans, Candida parapsilosis, Cryptococcus neoformans, Candida krusei, Candida glabrata and Candida tropicalis. Effectiveness against C. glabrata was lower for ITZ (MIC(90) 2 microg/ml, and for ABLC, 0.5 microg/ml). For Aspergillus fumigatus, activity of ITZ was superior in comparison with ABLC (MIC(90) 1 and 16 microg/ml, respectively); MIC(90) for Aspergillus niger was 4 and 2 microg/ml for ABLC and ITZ, respectively. Scedosporium spp. showed a low susceptibility to both ABLC and ITZ. In conclusion, ABLC and ITZ are useful alternatives for the treatment of severe fungal infections. The selection of an antifungal agent should be made considering the toxicological and pharmacological properties and cost/benefit relationship and be supported by the susceptibility of the isolate.

Fatal necrotizing stomatitis due to Trichoderma longibrachiatum in a neutropenic patient with malignant lymphoma: a case report.
Primary invasive mold infection of the oral cavity is a rare but serious complication in immunocompromised hosts. We report a case of fatal Trichoderma longibrachiatum stomatitis in a 66-year-old female patient with malignant lymphoma. The infection rapidly disseminated from the oral mucosa to the lungs during neutropenia. Despite intensive antifungal therapy with amphotericin B and itraconazole, there was a fatal progression of the condition. While Trichoderma species have been recognized to be pathogenic in profoundly immunosuppressed hosts, this is the first report of the primary oral focus causing a fatal infection.

Rhinocerebral mucormycosis: case report.
Rhinocerebral mucormycosis is a rare, fulminating opportunistic fungal infection caused by a fungus of the order mucorales. These fungi are ubiquitous, subsisting on decaying vegetation and diverse organic material. Although the fungi and spores of mucorales show minimal intrinsic pathogenicity towards normal persons, they can initiate aggressive and fulminating infection in the immune compromised host. Because rhinocerebral mucormycosis occurs infrequently it may pose a diagnostic and therapeutic dilemma for those who are not familiar with its clinical presentation. We present a patient with classical presentation of rhinocerebral mucormycosis involving the paranasal sinuses, the orbit and cranial base who, was treated by a combination of aggressive surgical and medical therapy and subsequently had surgical repair of the oral defect. The purpose of this presentation is to draw attention to the clinical presentation and pathogenesis of rhinocerebral mucormycosis and to emphasise the need for high index of suspicion in its diagnosis and management.

Liposomal amphotericin B and granulocyte colony-stimulating factor therapy in a murine model of invasive infection by Scedosporium prolificans.
We established a reproducible lethal disseminated infection by the opportunistic fungus Scedosporium prolificans in an immunosuppressed murine model. We compared the effectiveness of the combined administration of liposomal amphotericin B (LAMB) and granulocyte colony-stimulating factor (G-CSF) with that of either agent alone and with that of amphotericin B deoxycholate (AMB). LAMB + G-CSF and LAMB treatments improved survival significantly with respect to the untreated control. The mean survival times of these three groups were 13.2, 9.1 and 7.9 days, respectively. Culture results in terms of colony counts for samples of deep organs were lower in mice treated with the combined therapy, although differences were not significant. Combined LAMB + G-CSF therapy could be a promising approach for the treatment of disseminated infections of S. prolificans, although further studies are required to determine the most appropriate doses.

Invasive subglottal aspergillosis in a patient with severe aplastic anemia: a case report.
A 19-year-old female with aplastic anemia who developed subglottal aspergillosis is reported. She presented with fever, cough and stridor. Inspiratory dyspnea progressed rapidly and emergent tracheostomy was performed, which confirmed the diagnosis. In spite of intensive anti-fungal treatment combined with adoptive immunotherapy, Aspergillus infection expanded and she died of pulmonary aspergillosis. Autopsy revealed the fungal mass obstructing the trachea and disseminated pulmonary aspergillosis. Difficulties in diagnosis and management of subglottal Aspergillus infection are discussed.

In vitro fungicidal activities of voriconazole, itraconazole, and amphotericin B against opportunistic moniliaceous and dematiaceous fungi.
The NCCLS proposed standard M38-P describes standard parameters for testing the fungistatic antifungal activities (MICs) of established agents against filamentous fungi (molds); however, standard conditions are not available for testing their fungicidal activities (minimum fungicidal or lethal concentrations [MFCs]). This study evaluated the in vitro fungistatic and fungicidal activities of voriconazole, itraconazole, and amphotericin B against 260 common and emerging molds (174 Aspergillus sp. isolates [five species], 23 Fusarium sp. isolates [three species], 6 Paecilomyces lilacinus isolates, 6 Rhizopus arrhizus isolates, 23 Scedosporium sp. isolates, 23 dematiaceous fungi, and 5 Trichoderma longibrachiatum isolates). MICs were determined by following the NCCLS M38-P broth microdilution method. MFCs were the lowest drug dilutions that resulted in fewer than three colonies. Voriconazole showed similar or better fungicidal activity (MFC at which 90% of isolates tested are killed [MFC(90)], 1 to 2 microg/ml) than the reference agents for Aspergillus spp. with the exception of Aspergillus terreus (MFC(90) of voriconazole and amphotericin B, >8 microg/ml). The voriconazole geometric mean (G mean) MFC for Scedosporium apiospermum was lower (2.52 microg/ml) than those of the other two agents (5.75 to 7.5 microg/ml). In contrast, amphotericin B and itraconazole G mean MFCs for R. arrhizus were 2.1 to 2.2 microg/ml, but that for voriconazole was >8 microg/ml. Little or no fungicidal activity was shown for Fusarium spp. (2 to >8 microg/ml) and Scedosporium prolificans (>8 microg/ml) by the three agents, but voriconazole had some activity against P. lilacinus and T. longibrachiatum (G mean MFCs, 1.8 and 4 microg/ml, respectively). The fungicidal activity of the three agents was similar (G mean MFC, 1.83 to 2.36 microg/ml) for the dematiaceous fungi with the exception of the azole MFCs (>8 microg/ml) for some Bipolaris spicifera and Dactylaria constricta var. gallopava. These data extend and corroborate the available fungicidal results for the three agents. The role of the MFC as a predictor of clinical outcome needs to be established in clinical trials by following standardized testing conditions for determination of these in vitro values.

Nebulized amphotericin B prophylaxis for Aspergillus infection in lung transplantation: study of risk factors.
Aspergillus infection remains a major cause of morbidity and mortality after lung transplantation. Therefore, some strategies have been attempted, one of which is nebulized amphotericin B (nAB); however, the efficacy of this prophylaxis has not been shown clearly. The aim is to study whether nAB can protect against Aspergillus infection in lung transplant recipients.. A study of risk factors was conducted in 55 consecutive lung allograft recipients. Twenty-three potential risk factors were analyzed. In 44 (80%) patients, nAB was indicated as prophylaxis. Multivariate analysis using logistic regression was performed.. Eighteen of the 55 patients (33%) developed infection due to Aspergillus spp. Multivariate analysis showed nAB to be a preventive factor (odds ratio: 0.13; 95% confidence interval [CI] 0.02-0.69; p < 0.05) and cytomegalovirus (CMV) disease was an independent risk factor for developing Aspergillus infection (odds ratio: 5.1; 95% CI 1.35-19.17; p < 0.05). Only 1 patient required withdrawal of the prophylaxis owing to bronchospasm. nAB was well-tolerated in the remaining patients with only a few, mild, easily controlled side effects.. The present results show that nAB prophylaxis may be efficient and safe in preventing Aspergillus infection in lung-transplanted patients, and CMV disease increases the probability of Aspergillus infection.

A novel type of metastatically spreading subcutaneous aspergillosis without epidermal lesions following allogeneic stem cell transplantation.
Systemic mycosis is among the most feared opportunistic infections in the immunocompromised host. Difficulty and delay in diagnosis and treatment often result in poor outcomes. In this communication a metastatically spreading form of subcutaneous aspergillosis developed in a patient with a history of allogeneic stem cell transplantation for relapsed Hodgkin's lymphoma. Strikingly, necrotizing cutaneous papules or ulcerating lesions were absent. Diagnosis was accomplished after excision of a clinically non-suggestive subcutaneous nodule. Despite prompt initiation of antimycotic therapy the outcome was fatal; dosage of conventional and liposomal amphotericin B was limited due to treatment-related toxicities. This case report describes a novel form of aspergillosis and underlines the need for an aggressive diagnostic approach in severely immunocompromised patients.

We report the occurrence of invasive aspergillosis (IA) in nonallografted patients with multiple myeloma (MM) who were treated at hematology or oncology centers in Europe during 1984-1996. Thirty-one cases met the criteria for definitive (21 [68%]) or probable (10 [32%]) IA. Of these cases, 23 (74%) were reported during 1992-1996. Twenty-nine cases (94%) occurred in patients with Durie-Salmon stage 3 MM, and 2 (6%) occurred in patients with Durie-Salmon stage 2 MM. The median time between MM and IA diagnoses was 8 months (range, 1-75 months). Sixteen patients (51%) had a neutrophil count =500/mm3 for a median duration of 19 days (range, 10-37 days). Fourteen patients (45%) had recently received corticosteroid therapy, and 11 (36%), high doses of melphalan. Twenty-eight patients had primary pulmonary IA, and 3 had primary sinus IA. Forty-five percent of patients were considered to have died of IA. IA occurs as a potentially lethal opportunistic infection in intensively treated nonallografted patients with myeloma.

[Endogenous aspergillus endophthalmitis: a case repport].
We report a case of endogenous aspergillus endophthalmitis. This infection occurred in a young immunocompromised boy of 6 years old. The localisation of the chorioretinitis was unusual because out of the posterior area. The evolution was favorable with recovering of the visual acuity under general treatment and intravitreous injections.

Practice guidelines for the management of patients with blastomycosis. Infectious Diseases Society of America.
Guidelines for the treatment of blastomycosis are presented; these guidelines are the consensus opinion of an expert panel representing the National Institute of Allergy and Infectious Diseases Mycoses Study Group and the Infectious Diseases Society of America. The clinical spectrum of blastomycosis is varied, including asymptomatic infection, acute or chronic pneumonia, and extrapulmonary disease. Most patients with blastomycosis will require therapy. Spontaneous cures may occur in some immunocompetent individuals with acute pulmonary blastomycosis. Thus, in a case of disease limited to the lungs, cure may have occurred before the diagnosis is made and without treatment; such a patient should be followed up closely for evidence of disease progression or dissemination. In contrast, all patients who are immunocompromised, have progressive pulmonary disease, or have extrapulmonary disease must be treated. Treatment options include amphotericin B, ketoconazole, itraconazole, and fluconazole. Amphotericin B is the treatment of choice for patients who are immunocompromised, have life-threatening or central nervous system (CNS) disease, or for whom azole treatment has failed. In addition, amphotericin B is the only drug approved for treating blastomycosis in pregnant women. The azoles are an equally effective and less toxic alternative to amphotericin B for treating immunocompetent patients with mild to moderate pulmonary or extrapulmonary disease, excluding CNS disease. Although there are no comparative trials, itraconazole appears more efficacious than either ketoconazole or fluconazole. Thus, itraconazole is the initial treatment of choice for nonlife-threatening non-CNS blastomycosis.

Liver and brain mucormycosis in a diabetic patient type II successfully treated with liposomial amphotericin B.
A case of liver and brain mucormycosis in a 73-y-old diabetic patient is described. The patient presented with fever and a moderate, tender hepatomegaly and a C/T scan examination of the abdomen and brain showed multiple hepatic and cerebral nodular lesions. The largest of the liver lesions was aspirated and broad hyphae of mucor were demonstrated in the purulent material obtained. The patient was treated successfully (for 40 d) with intravenous liposomal amphotericin B and then with itraconazole for 3 months. To our knowledge, this is the first case of a diabetic patient with both liver and brain mucormycosis who has been treated successfully.

Zygomycosis in relapsed acute leukaemia.
We would like to report the use of liposomal amphotericin in eradicating mucormycosis in two patients who had relapsed acute leukaemia. The first patient with relapsed acute myeloid leukaemia developed a rapidly expanding solitary necrotic neck lesion associated with opacity of maxilliary sinus at a time when he was profoundly pancytopenic following high dose chemotherapy. The second patient was a 3-year-old boy with pre-B acute lymphoblastic leukaemia who developed a central nervous system relapse whilst on his first line treatment and was treated with more aggressive chemotherapy on the Medical Research Council Relapse Protocol. During a period of profound pancytopenia following re-induction therapy, including high dose steroids and prolonged course of antibiotics for proven septicaemia, he developed periorbital swelling and proptosis and a clinical diagnosis of rhinocerebral mucormycosis was made. Both patients were treated with high doses of liposomal amphotericin (Ambisome Nexstar). The doses were escalated to 10 and 15 mg/kg/day, resulting in successful eradication of the mucormycosis.

Successful non-surgical treatment of disseminated polymicrobial fungal infection in a patient with pancytopenia and graft-versus-host disease.
Invasive fungal infections after bone marrow transplantation have an extremely poor prognosis. Surgical excision in combination with antifungal therapy is considered necessary for treatment, especially for central nervous system (CNS) infection. We describe successful medical management with lipid complex amphotericin B (ABLC) and itraconazole, without surgical excision, of disseminated fungal infection involving the lungs and CNS in a patient with pancytopenia and graft-versus-host disease.

Chronic systemic (hepatosplenic) candidiasis in a patient with granulocytic sarcoma.
Chronic systemic (hepatosplenic) candidiasis (CSC) is a syndrome of invasive candidiasis characterized by fever without localizing signs or symptoms. It occurs predominantly in patients with acute leukemia, after prolonged severe neutropenia. We report a young woman who underwent extensive chemotherapy for granulocytic sarcoma of the ovary; CSC then developed in this patient. She was successfully treated with fluconazole and liposomal amphotericin B. Clinical presentation, diagnostic problems, and the current successful treatment with fluconazole and liposomal amphotericin B are discussed.

Candida infection in pediatric liver transplant recipients.
A retrospective review of 100 liver transplantations in 98 children was performed to determine the incidence of infection caused by Candida organism in these patients and to identify risk factors that may predispose to serious fungal infection. Thirty-one infections caused by Candida organisms developed during the initial 28 days posttransplantation: 19 were definite invasive infections (one deep site or one positive blood culture), 2 were probable invasive infections (three superficial sites), and 10 were urinary tract infections. Eleven of 19 patients had fungemia or a disseminated infection (two noncontiguous deep organs involved and/or positive blood cultures) and 8 of 19 had peritoneal candidiasis. Infection caused by Candida organisms was a contributing factor to mortality in 7 of 21 patients (case fatality rate of 33%) with invasive infection. Risk factors that were predictive for invasive infection by univariate analysis included the following: pretransplantation antibiotic therapy, length of transplant operation, transfusion requirement, number of days in the intensive care unit, number of days intubated, number of concurrent bacterial infections, number of antibiotics administered, number of laparotomies performed posttransplantation, retransplantation, hepatic artery thrombosis, bile leaks, and renal and respiratory failure. By logistic regression analysis, bile leak, hepatic artery thrombosis, preoperative steroid use, transfusion requirement, and the number of days intubated were identified as independent risk factors for invasive infection caused by Candida organisms. The use of prophylactic antifungal agents in high-risk patients may be important in reducing the serious morbidity and mortality associated with sepsis caused by Candida organisms in pediatric liver transplant recipients.

Hematogenous trichosporonosis in cancer patients: report of 12 cases including 5 during prophylaxis with itraconazol.
Twelve cases of Trichosporon spp. fungemias occurring in a national cancer institution within 10 years are described. The trend of hematogenous trichosporonosis within the last 10 years is increasing. While no cases occurred in 1988-1991, after 1991, Trichosporon spp. was the most common species among non-Candida spp. fungemias in 1993-1997. The 12 cases of fungemia included 5 that started while the patients were receiving prophylaxis with oral itraconazole, and 2 appeared despite empiric therapy with amphotericin B. Five of the 12 fungemias were catheter associated. Risk factors for fungemia were: central venous catheter, broad-spectrum antibiotics (third-generation cephalosporins plus aminoglycoside); all but 1 had neutropenia and were receiving antineoplastic chemotherapy. All but 2 of the patients died of systemic fungal infection (83.3% mortality). Amphotericin B was administered to all but 1 patient, who was not treated because he died the day after his culture was found to be positive for T. beigelii, before antifungals were administered. All cases infected with T. pullulans were catheter related, and all these patients died. One of the remaining 9 fungemias was caused by T. capitatum (Blastoschizomyces capitatus), and 8 by T. beigelii. Only 2 patients were cured, 1 with a combination therapy with amphotericin B plus fluconazole, and 1 with amphotericin B monotherapy. Several risk factors (neutropenia, acute leukemia, prior therapy or prophylaxis with antifungals and catheter as source of fungemia, breakthrough fungemia) were significantly associated with Trichosporon spp. fungemia, in comparison to 63 C. albicans candidemia occurring in the same period at the same institution. Attributable mortality of hematogenous trichosporonosis was also significantly higher (83.3% vs. 15.8%, P<0.001) than that of hematogenous candidiasis.

Antifungal prophylaxis during the early postoperative period of lung transplantation. Valencia Lung Transplant Group.
Fungal infections occur frequently in lung transplant patients, with the highest risk being in the early postoperative period (the initial hospitalization after lung transplantation). Aspergillus is responsible for more than half of all fungal infections, and Aspergillus has even been considered a contraindication for lung transplantation because of its difficult therapy and frequently fatal outcome. The aim of this article is to evaluate the success of an antifungal prophylaxis protocol to prevent fungal infection in the immediate postoperative period in lung transplant recipients.. From March 1994 to March 1997, we performed 52 lung transplants in 31 men and 21 women who received antifungal prophylaxis with fluconazole, 400 mg/d, and aerosolized amphotericin B, 0.6 mg/kg/d, during the postoperative period.. The mean (+/- SD) postoperative period duration was 49 +/- 27.5 days. No fungal infections were observed during this period, and all patients provided negative cultures. We also found no toxicity related to antifungal drugs. The dose of cyclosporine was easily adjusted in every recipient according to blood levels so that effective immunosuppression was not compromised.. In our study, the removal of the lungs and antifungal prophylaxis with fluconazole and aerosolized amphotericin B prevented fungal infection in the postoperative period in all 52 lung transplant recipients.

Rhodotorula rubra fungaemia in an immunosuppressed patient.
We report the case of a patient who, following surgical removal of an extensive tumour of the bowel, developed fungaemia. The yeast was isolated from repeated blood and urine cultures and identified as Rhodotorula rubra on the basis of macroscopic and microscopic features. Following treatment with amphotericin B, the patient's condition improved and the cultures became sterile.

Hepatosplenic candidiasis after neutropenic phase of acute leukaemia.
Hepatosplenic candidiasis following granulocytopenic periods is a relatively recently recognised problem in immunocompromised patients, particularly in those with acute leukaemia. We present three patients in whom diagnosis of hepatosplenic candidiasis was suspected on the basis of ultrasonographic (US), computed tomographic (CT) findings and confirmed by laparoscopy and biopsy of liver lesions. All three patients were successfully treated briefly with amphotericin B, followed by a longer period of fluconazole. In one patient laparotomy and surgical evacuation of abscesses was performed. This condition could be more often recognised by careful follow-up of liver function test, C-reactive protein level, ultrasonography, CT and MRI after recovery from chemotherapy-induced neutropenia.

Combined anti-fungal therapy and surgical resection as treatment of pulmonary zygomycosis in allogeneic bone marrow transplantation.
Opportunistic fungal infection is a rare but severe complication in allogeneic bone marrow transplant (BMT) recipients. We report a 49-year-old patient who developed pneumonitis after BMT, due to a Mucorales fungus (class Zygomycetes), Absidia corymbifera. Infections due to mucormycosis are likely to become increasingly recognized even though the occurrence after BMT has only been described sporadically. We postulate that the patient was contaminated before BMT despite no intensive drug treatment or other iatrogenic features, related to his poor living conditions and developed the infection during aplasia. He immediately received i.v. liposomal amphotericin B (AmBisome) and GM-CSF. Because there was no response, the infected area and necrotic tissue were resected. Despite initial clinical and biological improvement and the absence of Mucor on mycological examination post-surgery, the patient died 3 weeks later from bilateral pulmonary infection and multiorgan failure.

Problems in the design and reporting of trials of antifungal agents encountered during meta-analysis.
Meta-analyses may become biased if the reported data in the individual trials are biased and if overlap among trials cannot be identified. We describe the unanticipated problems we encountered in collecting data for a meta-analysis comparing a new antifungal agent, fluconazole, with amphotericin B in patients with cancer complicated by neutropenia. In 3 large trials that comprised 43% of the patients identified for the meta-analysis, results for amphotericin B were combined with results for nystatin in a "polyene" group. Because nystatin is recognized as an ineffective drug in these circumstances, this approach creates a bias in favor of fluconazole. Furthermore, 79% of the patients were randomized to receive oral amphotericin B, which is poorly absorbed and not an established treatment, in contrast to intravenous amphotericin B, which was administered in 4 of 5 placebo-controlled trials, or 86% of patients. It was unclear whether there was overlap among the "polyene" trials, and it is possible that results from single-center trials were included in multicenter trial reports. We were unable to obtain information to clarify these issues from the trial authors or the manufacturer of fluconazole. Two of 11 responding authors replied that the data were with the drug manufacturer and two indicated that they did not have access to their data because of change of affiliation. In the meta-analyses, fluconazole and amphotericin B (mostly given orally) had similar effects (13 trials), whereas nystatin was no better than placebo (3 trials). Since individual trials are rarely conclusive, investigators, institutions, and pharmaceutical companies should provide essential details about their work to ensure that meta-analyses can accurately reflect the studies conducted and that patients will realize maximum benefits from treatments. We recommend that investigators keep copies of their trial data to help facilitate accurate and unbiased meta-analyses.

Itraconazole for the treatment of pulmonary aspergillosis in heart transplant recipients.
The objective of this study was to evaluate the effects of itraconazole as a first choice drug in the treatment of pulmonary aspergillosis in heart transplant recipients. Heart transplant recipients suffering from invasive pulmonary aspergillosis were included in this study. Group 1 included 4 patients treated with i.v. itraconazole (Janssen Pharmaceutica) 400 mg daily, as a first choice drug for 28 d. Itraconazole was discontinued and amphotericin-B was started before the 28th day if clinical or radiographic worsening was observed. Group 2 included 3 patients treated with amphotericin-B as a first choice drug. Itraconazole was discontinued in all patients of Group 1 after 12-26 d of treatment because of radiographic worsening (n = 3) or combined clinical and radiographic worsening (n = 1). Subsequent treatment with amphotericin-B resulted in improvement of all patients. On a 5-yr follow-up period no relapse of aspergillosis was observed in 3 of them. The fourth patient expired from cerebral hemorrhage. The 3 patients of Group 2 treated with amphotericin-B showed a gradual improvement, and all were doing well on a 2-yr follow-up. In conclusion, in our study population consisted of heart transplant recipients amphotericin-B was superior to itraconazole in the treatment of invasive pulmonary aspergillosis.

Rhinocerebral mucormycosis treated with amphotericin B colloidal dispersion in three patients.
Rhinocerebral mucormycosis (zygomycosis) primarily affects diabetic or immunosuppressed patients and typically progresses rapidly, necessitating surgical excision and antifungal therapy with amphotericin B. Large doses of amphotericin B are required for cure, causing significant renal toxicity. Amphotericin B colloidal dispersion (ABCD; Amphocil, Sequus Pharmaceuticals, Menlo Park, CA) is a 1:1 complex of cholesteryl sulfate and amphotericin B, which results in significant reduction of toxicity, especially nephrotoxicity. We describe three patients with life-threatening rhinocerebral mucormycosis treated with ABCD. All patients had high serum creatinine levels due to prior treatment with amphotericin B; these levels reverted to normal during treatment with ABCD. Two patients with diabetes mellitus were cured after receiving a combination of surgery and ABCD therapy. The third patient, who had myelodysplastic syndrome, had an initial good response, with cure of the fungal infection; however, he eventually died of his primary illness. To the best of our knowledge, this is the first detailed clinical description of the treatment of mucormycosis with ABCD.

Fungal purulent constrictive pericarditis in a heart transplant patient.
Purulent pericarditis caused by Candida species is rare and is associated with very high mortality. Immunosuppressed transplant patients are particularly susceptible to fungal infections.

Disseminated histoplasmosis successfully treated with liposomal amphotericin B following azathioprine therapy in a patient from a nonendemic area.
Histoplasma infections in Europe are rare, and acute disseminated histoplasmosis has been observed only in immunocompromised persons. An unusual case of autochthonous disseminated histoplasmosis in a 22-year-old Spanish man who had been treated with azathioprine and prednisone for 4 weeks before admission is reported. The development of an acute form of the disease may represent an endogenous reactivation of a latent infection as a complication of immunosuppression resulting from the use of these drugs. This case illustrates the potential risk of this opportunistic fungal infection in patients receiving azathioprine therapy, an association that has been rarely described before.

Hyperbaric oxygen therapy for cutaneous/soft-tissue zygomycosis complicating diabetes mellitus.
A 24-year-old female diabetic patient was hospitalized because of ketoacidosis and a necrotic wound on the hand. Debridement and antibiotic therapy failed to halt the process. After demonstration of Mucor in cultures from the wound, the patient underwent extensive surgery and amphotericin B was administered. When the necrotic process continued despite these measures, adjunctive hyperbaric oxygen (100% O2 at 2.5 ATA for 90 minutes) was administered daily for a total of 21 treatment sessions. She gradually improved, and at 2 months follow-up most of the wound had healed. Although the mortality rate of cutaneous/soft-tissue zygomycosis is markedly lower than that of the rhinocerebral form, morbidity is still considerably high. Successful use of hyperbaric oxygen has been reported in rhinocerebral zygomycosis, and it may have been of benefit in this high-risk patient by preventing local and systemic spreading of the fungus. This report is the first case of the use of hyperbaric oxygen for cutaneous/soft-tissue zygomycosis. It is suggested that hyperbaric oxygen be considered for this indication in diabetic patients as an adjunct to surgery and amphotericin B.

A comparative analysis of lipid-complexed and liposomal amphotericin B preparations in haematological oncology.
No comparative clinical information on the properties of lipid-associated amphotericin preparations is presently available. In this single-centre retrospective analysis over a 5-year period the indications, efficacy and toxicity of true liposomal amphotericin (AmBisome) were compared with a lipid complexed preparation (Abelcet). In a novel approach APACHE III scores were used in addition to neutrophil counts, disease status and additional immunosuppression to accurately assess the severity of illness in both groups and enable valid comparison. Overall, AmBisome at a median dose of 1.9 mg/kg/d was found to have similar clinical outcome to Abelcet at a median dose of 4.8 mg/kg/d. Nephrotoxicity and electrolyte abnormalities were similar in both groups. Rigors and febrile episodes were more common with Abelcet. Prospective randomized comparative trials are required to clarify the optimum dosages and therapeutic and economic issues associated with these agents.

An EORTC multicentre prospective survey of invasive aspergillosis in haematological patients: diagnosis and therapeutic outcome. EORTC Invasive Fungal Infections Cooperative Group.
The EORTC Invasive Fungal Infections Cooperative Group (IFICG) conducted a prospective survey by questionnaire of all cases of invasive aspergillosis (IA) in cancer patients to ascertain current diagnostic and therapeutic approaches.. All members of the IFICG were asked prospectively to complete a detailed questionnaire for each IA case identified in their institution over a 12-month period.. One hundred and thirty questionnaires were returned. All cases were independently evaluated (DWD & JC) and 123 were eligible. Cases came from 20 hospitals in eight countries and the number of cases per institution varied from 1-21. Acute myeloid leukaemia (AML) (60, 49%), acute lymphoblastic leukaemia (ALL) (21, 17%) and lymphoma (11, 9%) were the most frequent underlying diseases, and 16 (12%) patients had received an allogeneic bone marrow transplant. Pulmonary involvement was present in 87%, infection of sinuses/nose in 16% and brain in 8%. The chest radiograph was initially normal in 9% of those with primary pulmonary disease. The diagnosis was confirmed in 50%, probable in 31% and possible in 19%. The evidence for IA was on the basis of clinical and radiological features alone in 28%, with culture or histology in another 31% and 9%, respectively, and with both culture and histology in 29%. In three (2%) patients with diagnosis was based on culture or histology alone. Treatment was given to 120 patients (98%)-amphotericin B 75%, lipid-associated amphotericin B 36%, itraconazole 40%, flucytosine 12%, growth factors 33%, lobectomy 5%. At 3 months after diagnosis or first suspicion of IA, 44 (36%) patients were alive and 79 (64%) dead. Outcome was best in those with AML (30% death and 46% with a complete antifungal response or cure). Growth factors (mostly granulocyte colony stimulating factor) appeared not to influence outcome (P = 0.99).. IA remains a considerable diagnostic and therapeutic challenge. No single diagnostic procedure was universally successful and a multifaceted approach including surgery is necessary. There was no discernable difference in outcome between initial therapy with amphotericin B, itraconazole or lipid-associated amphotericin B, although numbers are limited and the study was retrospective.

[Must we be really concerned about amphotericin B toxicity in oncology patients?].
Amphotericin B treatment in oncological patients is irrepaceable due to the high frequency of mycotic infections. From data in the literature ensues that the most serious undesirable effect of amphotericin B is nephrotoxicity, manifested by a reduced glomerular filtration and impaired tubular function (in particular the development of hypokalemia, and hypomagnesaemia). Prophylaxis of nephrotoxicity is despite major efforts unsatisfactory. In the submitted work the authors tested in a major group of patients their working hypothesis based on previous observations, that prophylactic replacement of the increasing ion losses in urine during amphotericin B treatment without waiting for a decline of serum concentrations of these ions, along with adequate hydration delays or eliminates the decline of glomerular functions.. During amphotericin B therapy of 25 oncological patients renal functions, Na, K and Mg urinary excretion and the serum concentrations of these ions were followed up in detail. The urinary losses were replaced. No overall prophylaxis to prevent acute toxic reactions associated with administration of the drug was used. The mean dose of amphotericin B was 0.82 mg/kg, the mean diuresis 3662 ml/24 hours. Acute toxic reactions calling for hydrocortisone administration were observed only in 6% of the patients. During treatment the urinary K and Mg losses increased significantly and had to one replaced. There was also a significant increase of the excretory fractions of K and Na. However there were no significant changes of serum ions nor a rise of creatinine. The creatinine clearance even increased slightly though insignificantly (1.384 ml/s as compared with 1.392 ml/s).. Consequential hydration of patients and prophylactic replacement of urinary ion losses during amphotericin B therapy are effective in preventing ion disbalances and a decline of glomerular functions. Acute toxic reactions associated with administration of amphotericin B are infrequent. Topics: Amphotericin B; Antifungal Agents; Humans; Kidney; Mycoses; Neoplasms; Opportunistic Infections | 1998 |

Cutaneous mucormycosis due to Absidia corymbifera occurring after bone marrow transplantation.
Mucormycosis is an uncommon severe life-threatening fungal infection in the immunocompromised host caused by fungi belonging to the order Mucorales, most commonly Rhizopus arrhizus (R. oryzae). We report a patient who developed a severe right atrial catheter exit site infection with Absidia corymbifera. The catheter was removed and necrotic tissue debrided. With liposomal amphotericin B and G-CSF, the infection subsided. He remains well 8 months later.

Comparative analysis of prognostic indicators of aspergillosis in haematological malignancies and HIV infection.
The objective of this study was to identify the prognostic factors influencing the outcome of aspergillosis in two models of immunodeficiency, namely haematological malignancies and HIV infection. The study is based on a 5 year prospective logistic regression analysis of risk factors, clinical features, radiological findings and therapy affecting the prognosis of aspergillosis in 43 patients, i.e. 27 haematological neoplastic patients (group A) and 16 HIV infected patients (group B). Univariate analysis indicated that neutropenia (P = 0.02), haemoptysis (P = 0.03) and concomitant AIDS (P = 0.02), negatively influenced the prognosis of aspergillosis. Comparing the two groups of patients, significant differences emerged in the prognostic indicators. In particular respiratory failure (P = 0.02) and radiological bilateral involvement of the lungs were associated with a poor prognosis in group A (P = 0.04) and low (2100/mm3) T CD4+ cell count in group B (P = 0.02). At variance, a better prognosis was documented in patients treated with sequential therapy (amphotericin B and itraconazole) only within the group of haematological patients (P = 0.003). On multivariate analysis sequential therapy (P = 0.01) and AIDS (P = 0.03) were independent prognostic indicators of aspergillosis. In conclusion, our prospective study indicates that aspergillosis, although an uncommon event in patients with HIV infection, has a more severe prognosis in comparison to haematological patients. Future prospective clinical trials are necessary to confirm the real importance of the sequential therapy, with amphotericin B and itraconazole, in patients with aspergillosis.

Rhinocerebral mucormycosis: evolution of the disease and treatment options.
Rhinocerebral mucormycosis is recognized as a potentially aggressive and commonly fatal fungal infection. The classic presentation is involvement of nasal mucosa with invasion of the paranasal sinuses and orbit. Mucormycosis is most commonly seen in association with diabetic ketoacidosis, but disease demographics have changed with the onset of AIDS and the advent of powerful immunosuppressive drugs. Treatment includes aggressive debridement, systemic antifungal therapy, and control of underlying comorbid factors. Although surgical intervention remains essential, advances in medical therapy have permitted a more limited surgical approach to minimize functional loss without compromising survival. We present the UCLA experience with rhinocerebral mucormycosis from 1955 to 1995, with emphasis on the evolution of disease presentation and alternative treatment options.

Disseminated miliary cerebral candidiasis.
We present a case of disseminated intracranial infection by Candida albicans in a 5-year-old girl who had fever and a change of consciousness after surgery for complex congenital heart malformation. MR imaging revealed multiple small ring-enhancing hemorrhagic abscesses. One year after antifungal treatment, the abscesses and ventriculomegaly were almost completely resolved. The patient was discharged in a stable but vegetative condition.

Blastomycosis in children.
Children acquire blastomycosis, with rare exceptions, through the respiratory route. Nearly half of those who are infected may be asymptomatic. Cough is the most common symptom and is usually without sputum production, and hemoptysis is not noted. Other symptoms are chest pain (described as tightness or pain when breathing), weight loss, night sweats, and loss of appetite. The severity of illness is variable and may simulate an upper respiratory infection, bronchitis, pleuritis, or pneumonia. As in adults, an overwhelming infection may cause respiratory failure even in immunocompetent children and in immunocompromised children who live in or travel to endemic areas are susceptible to infection. Some reports based on consecutive cases note extrapulmonary dissemination commonly in children, whereas dissemination is rarely noted in outbreak cases. Chronicity of the disease favors extrapulmonary dissemination. Chest radiograph patterns are alveolar infiltrates, consolidation, and nodule(s), and these may be accompanied by cavitation. Diagnosis is suspected when the symptoms that mimic common respiratory infections persist for more than 2 weeks and by a history of residence or travel to an endemic area. Chest radiographic findings of nodule(s) or cavitation further increase the suspicion. Confirmation of diagnosis is by microscopic examination and culture of sputum. When expectorated sputum is unavailable, bronchoscopy with lavage and biopsy or percutaneous needle biopsy of lung is the appropriate next step. Disease that is progressive or severe or disseminated to other organs should be treated. Amphotericin B is effective and results in excellent cure rates. Experience using oral azoles is limited in children.

A fatal case of severe SLE complicated by invasive aspergillosis.
We report on the case of a 25-year-old female with severe systemic lupus erythematosus (SLE) who presented with pancytopenia, fever, arthralgia and abdominal pain. After antibiotic treatment, the patient was afebrile for 3 days before her temperature rose again. Dyspnoea and cough pointed towards pneumonia which was confirmed by X-ray. Different antibiotics and the antimycotic agent fluconazol were given. The lupus flare was treated with high-dose prednisolone. After a couple of days, the dyspnoea increased and mechanical ventilation became necessary. Bronchoscopy and transbronchial biopsy revealed the diagnosis of invasive aspergilloses. Despite of an immediate treatment with amphotericin B, the patient died because of respiratory insufficiency. The literature on aspergillosis in SLE is reviewed and prophylactic, diagnostic and therapeutic options are discussed for this infectious complication which has an 80% mortality in patients with SLE.

Histoplasma capsulatum necrotizing myofascitis of the upper extremity.
Necrotizing myofascial fungal infections of the upper extremity is a rare event even in immunocompromised hosts. We report the course of a renal transplant patient who developed extensive necrotizing myofascial infection of an upper extremity secondary to Histoplasma capsulatum. Initial, functional, upper limb salvage was achieved after aggressive surgical debridement and high doses of amphotericin B. The patient ultimately succumbed to systemic fungal sepsis. The etiology and treatment of these infections are discussed.

Disseminated histoplasmosis in renal allograft recipients.
Histoplasmosis, an opportunistic fungal infection endemic in the Ohio and Mississippi river valleys, is caused by a dimorphic fungus Histoplasma capsulatum. Most infections are asymptomatic or self-limited febrile illness. Immunosuppressed renal transplant recipients are susceptible to a disseminated disease. We report 5 cases of disseminated histoplasmosis seen in our institute over a period of 25 years amongst 1074 renal transplant recipients. The duration of immunosuppression prior to the diagnosis of infection ranged from 84 days to 14 years. All patients had pulmonary involvement. Three patients received an antilymphocyte preparation and 1 patent received intravenous pulse steroids in the 3 months prior to the onset of infection. Histopathologic examination of the involved organ(s) provided rapid diagnostic information allowing early treatment with amphotericin B. All infections resolved with no relapses to date. In conclusion immunosuppressed patients are more prone to disseminated histoplasmosis. Early recognition and prompt treatment with amphotericin B resolved the infection without relapse.

Amphotericin B responsive Scedosporium apiospermum infection in a patient with acute myeloid leukaemia.
A 71 year old man with newly diagnosed acute myelomonocytic leukaemia developed a soft tissue infection of his foot during his first course of chemotherapy. Scedosporium apiospermum was isolated from the lesion, which resolved rapidly on treatment with intravenous amphotericin B despite being resistant in vitro to this agent. This observation suggests that sensitivity testing of S apiospermum should be interpreted with caution and that clinical response may be a better indicator of outcome.

[Mucormycosis--a rare complication in patients with diabetes mellitus].
Mucormycosis usually occurs in immunocompromised patients or in patients with diabetes mellitus. Pathogens are moulds of the mucorales species. The diagnosis is made by histological examination of biopsies. A 39 year-old patient with insulin-dependent diabetes mellitus was admitted with a tentative diagnosis of a tumour of the maxilla. After diagnosis of hyphae of the mucorales species, the patient's diabetes was stabilised and he was treated over 17 weeks with amphotericin B (40 mg per day) and made a good recovery. A 58 year-old insulin-dependent patient with ethmoidali and sphenoidali sinusitis did not respond to antibiotic therapy. Mucormycosis was diagnosed by means of biopsy. Although treatment with amphotericin B was started, the patient died after 3 weeks due to multiple organ failure.

Cryptococcosis as an opportunistic infection in immunodeficiency secondary to paracoccidioidomycosis.
We describe the case reports of two patients with immunodeficiency secondary to paracoccidioidomycosis (PCM) and opportunistic Cryptococcus neoformans infections. Secondary immunodeficiency likely occurred as a consequence of the intestinal loss of proteins and lymphocytes associated with malabsorption syndrome due to obstructed lymphatic drainage. Both patients had had severe abdominal involvement during the acute PCM disease. Immunological evaluation showed cellular and humoral immunity impairment. Cryptococcosis manifested as relatively well circumscribed lesions: osteolytic lesions of the skull in one patient, and pulmonary nodules in the other. The latter was treated surgically and with amphotericin B, whereas the other was treated with the combination amphotericin-B and flucytosine. Both patients had a good response to treatment with complete regression of the lesions. They have now 2 and 4 years of follow-up with maintenance therapy and no indication of reactivation of the infection. PCM also did not reactivate. The clinical and immunological characteristics of these patients are discussed and compared to the opportunistic C. neoformans infections of AIDS and transplant patients.

Axenic growth and drug sensitivity studies of Balamuthia mandrillaris, an agent of amebic meningoencephalitis in humans and other animals.
A cell-free growth medium for the opportunistic pathogenic ameba Balamuthia mandrillaris is presented. This represents an advance over the use of monkey kidney cells for growth of the amebas and can be helpful in isolation of these amebas from brain tissue from cases in which amebic meningoencephalitis is a diagnostic possibility, as well as for biochemical and molecular biological studies. Three isolates of Balamuthia have been cultured in this medium. The cell-free growth system was also used to screen cultures for sensitivity to a variety of antimicrobial agents. Of the various drugs tested, pentamidine isethionate was most effective against amebas (ca. 90% inhibition after 6 days of exposure), but the drug was amebastatic and not amebacidal in the axenic system at the highest concentration tested (10 micrograms/ml).

Cutaneous mucor infection treated with wide excision in two children who underwent marrow transplantation.
Cutaneous mucor infection developed in two children who had undergone bone marrow transplantation for treatment of leukemia. One infection occurred before transplantation, and the other occurred during the period of profound neutropenia after transplantation. Both children were treated with an extensive wide excision of the infected area, and there was no evidence of mucor along the resected edges of tissue. Both patients received extensive treatment with either amphotericin (case 1) or amphotericin and itraconazole (case 2). These two cases represent aggressive management of cutaneous mucor infections, which is believed to be required for the successful completion of a marrow transplantation procedure.

Dark ring sign: finding in patients with fungal liver lesions and transfusional hemosiderosis undergoing treatment with antifungal antibiotics.
To describe the MR appearance of necrotizing fungal granulomas occurring in the liver of leukemic patients with hepatosplenic fungal disease and transfusional hemosiderosis on antifungal antibiotics.. Four patients with acute myelogenous leukemia (n = 2) or acute lymphocytic leukemia (n = 2) who developed hepatosplenic fungal disease, and were treated with antifungal medication, underwent MRI examination on a 1.5 T MR imager. MR images were prospectively evaluated and correlated with liver biopsy (three patients), and clinical picture (one patient).. Multiple liver lesions measuring approximately 1 cm in diameter were identified in all patients. Lesions possessed a distinctive MR appearance: central mild hyperintensity with a peripheral ring of very low signal intensity on precontrast T1- and T2-weighted images. The central region of the lesions enhanced following gadolinium administration with the peripheral ring remaining low in signal intensity.. Necrotizing fungal granulomas in the liver of patients with transfusional hemosiderosis on treatment with antifungal antibiotics have a distinctive appearance of moderate high signal intensity center on T1- and T2-weighted and postgadolinium MR images with a peripheral rim of low signal intensity. This appearance reflects the presence of iron-laden macrophages in the periphery of granulomas and may be expected in processes that initiate an immune response involving aggregation of macrophages in the liver of patients with transfusional iron overload.

Amphotericin-induced heart-rate decrease in children.
We describe six children with acute decreases in heart rate temporally related to amphotericin B administration. All patients had achieved their maximal dose within 3 to 4 days. Heart-rate drops occurred as early as day 3 but could be delayed up to day 7 after start of therapy. The mean heart rate dropped from 104 +/- 8/min (range 96 to 114) to 62 +/- 8/min (range 48 to 72) (P = 0.0001). A slower heart rate than baseline was noted during the entire duration of drug administration, from 60 minutes of starting the infusion to 220 minutes (mean 120 +/- 40) after discontinuation of the infusion. This reaction was noted in six of 90 (6.7%) patients who had amphotericin. These six children were compared with six age-matched children who received the drug but in whom such changes in heart rate did not develop. The method of administration of amphotericin B was similar in both patients and controls, starting with 0.25 mg/kg/day and increasing by 0.25 mg/kg/day up to 1 mg/kg/day. Children with heart-rate drop received amphotericin for 4.6 +/- 1.8 days, significantly shorter than their controls (12.6 +/- 6.9 days) (P = 0.02), suggesting that this adverse effect has led to early discontinuation of amphotericin therapy. Physicians and nurses caring for children receiving amphotericin B should be aware of this potential adverse effect, which can be serious in a patient with an underlying heart condition or in a patient who is already on heart-rate-lowering drugs.

Risk factors for systemic fungal infections in liver transplant recipients.
The risk factors for systemic fungal infections were analysed retrospectively in 186 orthotopic liver transplant procedures performed in 152 patients between June 1985 and January 1993. The total incidence of systemic fungal infections was 16.5% (25/152). The incidence of disseminated candidiasis, aspergillosis, and combined candidiasis and aspergillosis was 6.5% (n = 10), 7.2% (n = 11) and 2.6% (n = 4), respectively. Mortality associated with systemic fungal infections was 80% (20 of 25 patients). There were ten cases of disseminated candidiasis, with 4 patients surviving, and 11 cases of invasive aspergillosis, with 1 patient surviving. All patients with combined systemic fungal infection died. To identify perioperative risk factors, 39 variables were used to compare patients with systemic fungal infections versus those without fungal infections. Fourteen variables were significantly associated with systemic fungal infections by univariate analysis. A consecutive logistic regression analysis revealed that the amount of fresh frozen plasma transfused due to poor initial function of the allograft and acute renal failure requiring hemofiltration were independently significant risk factors for systemic fungal infections. There was no statistical correlation between systemic fungal infections and the underlying liver disease, previous long-term corticosteroids and the postoperative immunosuppressive therapy. Risk factors identified in this study should be considered in the postoperative care of the individual liver transplant recipient. In our study a poor initial function of the hepatic allograft substantially increased the risk of systemic fungal infection.

Suppurative cutaneous granulomata caused by Microascus cinereus in a patient with chronic granulomatous disease.
We describe a patient with chronic granulomatous disease who presented with erythematous papular skin lesions on the chest, back, and arm. Examination of biopsy specimens from the lesions on the arm and back showed suppurative granulomata in association with acute and chronic inflammation. Histopathologic examination of a specimen from the lesion on the arm revealed fungal elements, and cultures yielded Microascus cinereus. The patient was treated with 2.5 g of intravenous amphotericin B, and the lesions resolved. We report what is, to our knowledge, the first case of invasive disease due solely to M. cinereus.

[Favorable outcome of orbital nasal sinus mucormycosis complicating the induction treatment of acute lymphoblastic leukemia].
Most cases of mucormycosis occur in immunosuppressed children. Intracranial extension is lethal and must be prevented with early specific treatment.. A 42 month-old boy was admitted suffering from acute lymphoblastic leukemia. Edema of the left eyelid developed on the sixth day of induction chemotherapy. Mucormycosis was suspected because of gradual extension of infection to nasal ala and periorbital area with fever, edema of nasal turbinates and nasal black secretions. Chemotherapy was discontinued and the patient was given intravenous amphotericin B (1.0 mg/kg/day) and heparin associated with G.CSF. Improvement was only temporary and scan examination performed on day 17 showed involvement of the orbit, eye and wall of the maxillary sinus; cultures of secretions were positive for staphylococcus and Absidia corymbifera. Remission of leukemia was obtained a few days later permitting surgical resection of involved tissues on day 30. A relapse of mucormycosis was observed six weeks later despite prolonged administration of amphotericin B requiring extended resection of necrotic areas and replacement of amphotericin B by its liposomal form (Ambisome). Bone marrow relapse of leukemia required further chemotherapy. The patient is in good condition 30 months after the initial symptoms.. Our patient seems to be the first with prolonged remission of facial mucormycosis and acute leukemia despite relapse of both diseases. This favorable outcome could be due to the use of Ambisome.

Experience with liposomal Amphotericin-B in 60 patients undergoing high-dose therapy and bone marrow or peripheral blood stem cell transplantation.
60 patients undergoing bone marrow or stem cell transplantation were treated with liposomal Amphotericin-B for documented or suspected mycosis. 34 patients had a prior course of conventional Amphotericin-B with the following adverse effects: increasing creatinine above 1.4 mg/dl (n = 17), increasing creatinine below 1.5 mg/dl (n = 9), no response (n = 6), and clinical side-effects (n = 4). Liposomal Amphotericin-B failed in 6/7 patients with culture-proven mycosis who died from infection with Aspergillus (n = 2) and Candida (n = 4), respectively. One patient with Candida lambica sepsis was cured. No patient with clinically or serologically suspected or diagnosed infection died from mycosis. Liposomal Amphotericin-B was well tolerated in 57 patients, even after side-effects of the conventional formulation. Adverse effects occurred in three cases, requiring the withdrawal of the drug in one patient. Due to toxic side-effects of the high-dose therapy and transplant-related complications, it was difficult to evaluate the influence of liposomal Amphotericin-B on laboratory parameters. Eight patients showed a decrease of creatinine levels, which had increased above normal values under preceding therapy with conventional Amphotericin-B. Liposomal Amphotericin-B is well tolerated in patients undergoing high-dose therapy and bone marrow transplantation. The efficacy of liposomal Amphotericin-B needs to be investigated in randomized studies in comparison with conventional Amphotericin-B.

Successful treatment of invasive thoracopulmonary mucormycosis in a patient with acute lymphoblastic leukemia.
Pulmonary mucormycosis associated with hematologic malignancy is an uncommon, but important opportunistic fungal pneumonia that is usually a fatal infection. Only a few survivors of pulmonary mucormycosis have been reported.. A case report of invasive thoracopulmonary mucormycosis during remission-induction therapy for acute lymphoblastic leukemia and a review of the literature are presented.. The fungal lesions extended to both lungs, the left ribs, and intercostal muscles. Percutaneous needle biopsy and immunostaining of the fungal hyphae established the diagnosis of thoracopulmonary mucormycosis. The patient was treated with granulocyte-colony stimulating factor (G-CSF) and intravenous amphotericin B for 9 weeks and the lesions in the right lung disappeared. Left pneumonectomy and partial resection of the chest wall were later performed. The left lung was grossly necrotic and contained a large cavity and bronchopulmonary fistula. Thereafter, antileukemic therapy was resumed and completed without recurrence of mucormycosis or leukemia.. In the management of mucormycosis, the addition of G-CSF to the conventional treatment may substantially improve outcome.

We describe here a case of cryptococcal empyema thoracis and periauricular pyogenic abscess in a child with Bruton's agammaglobulinaemia. The cryptococcal empyema thoracis was treated with intravenous amphotericin B and intravenous fluconazole for six weeks followed by oral fluconazole. The pyogenic periauricular abscess was surgically drained and treated with intravenous ceftazidime and cloxacillin for two weeks. He also received monthly intravenous immunoglobulin.

[Pulmonary mucormycosis in leukemic patients. Apropos of 2 cases].
Mucormycosis is a rare fungal infection that has been described mainly in oncologic and diabetic patients. We here report the cases of two leukaemic patients in whom pulmonary mucormycosis was diagnosed. Prompt diagnosis, therapy with amphotericin B and surgery when possible, are the cornerstones in the treatment of this fungal infection. Although infrequent, this infection must be suspected in oncohaematological patients with lung infiltrates.

Liposomal amphotericin B in the treatment of fungal infections in neutropenic patients: a single-centre experience of 133 episodes in 116 patients.
Liposomal amphotericin B (AmBisome) was used for suspected or confirmed fungal infection complicating 133 neutropenic episodes in 116 patients not tolerating, or not responding to, conventional amphotericin. Adverse effects were infrequent and no significant renal impairment resulted. Acute reactions occurred in five patients, reversible hepatic dysfunction in 23, and hypernatraemia in 17. The putative mycosis resolved with AmBisome treatment in 81 episodes (61%) and progressed with fatal outcome in 25 (19%), but the diagnosis was equivocal in most, and in 27 episodes (20%) evidence indicating nonfungal pathogenesis emerged. Treatment efficacy is, however, evaluable in those with proven aspergillosis. 13/17 patients with confirmed invasive aspergillosis responded to AmBisome (77%), conventional amphotericin having failed in 11. Treatment was successfully discontinued when the neutrophil count was < 1 x 10(9)/l in eight responders (61%). In four further patients treated for suspected aspergillosis, disseminated infection was documented at post-mortem, but the true incidence is unknown. This analysis confirms that AmBisome is well tolerated and effective against invasive mycoses in neutropenic patients, and may salvage patients when conventional amphotericin proves excessively toxic or ineffective.

Zygomycosis due to Mucor circinelloides in a neutropenic patient receiving chemotherapy for acute myelogenous leukemia.
Mucor circinelloides form circinelloides has rarely been associated with human disease, even in immunocompromised patients. We report a case of cutaneous zygomycosis caused by M. circinelloides in a 23-year-old neutropenic woman receiving consolidation chemotherapy for acute myelogenous leukemia. The organism was exquisitely susceptible to amphotericin B. Despite the fact that the patient was profoundly neutropenic for an additional 3 weeks, the lesions began to resolve during therapy, and no surgical debridement was required.

Successful combined surgical and medical treatment of fusarium infection after bone marrow transplantation.
The usual management of opportunistic fusarium infection in the immunocompromized patient is with systemic antifungals, despite which little impact is made on the mortality which approaches 100%. We describe a case of fusarium infection of the foot in a bone marrow transplant recipient which was successfully managed with local wide excisional surgery and intravenous liposomal amphotericin B.

[Candida chorioretinitis: current therapeutic approach].
Candida endophthalmitis may occur either during systemic Candida infection (candidemia), particularly in immunocompromised hosts or as a single manifestation in drug abusers.. One case of endogenous candida endophthalmitis (ECE) in a patient with systemic candidiasis and four cases of drug abusers are presented. Well confined inflammatory lesions in retina and choroid were adequately treated with systemic Amphotericin B administration, whereas lesion extension beyond the internal limiting membrane towards the vitreous required surgical management, to remove epiretinal fibrovascular tissue, and intravitreal Amphotericin B injection.. In all cases, treatment resulted to regression of the lesions, however visual function recovery depends on location of chorioretinal lesions.

Efficacy of unilamellar liposomal amphotericin B in treatment of pulmonary aspergillosis in persistently granulocytopenic rabbits: the potential role of bronchoalveolar D-mannitol and serum galactomannan as markers of infection.
A model of primary pulmonary aspergillosis in rabbits was developed to reproduce the persistent levels of profound granulocytopenia and the histopathologic features of bronchopneumonia, vascular invasion, and hemorrhagic infarction encountered in humans. D-mannitol was detectable in bronchoalveolar lavage fluid by gas-liquid chromatography/mass spectroscopy, and galactomannan was measurable in serum by latex agglutination immunoassay. A pharmacokinetically distinctive unilamellar vesicle formulation of liposomal amphotericin B, 5 mg/kg/day intravenously, compared with high-dose conventional desoxycholate amphotericin B, 1 mg/kg/day intravenously, was more effective in preventing nephrotoxicity, increasing survival, reducing the number of viable organisms, and decreasing tissue injury due to Aspergillus organisms. Thus, D-mannitol in lavage fluid and galactomannan in serum may be useful markers of pulmonary aspergillosis, and liposomal amphotericin B was significantly more effective and safer than desoxycholate amphotericin B for treatment of pulmonary aspergillosis in profoundly granulocytopenic rabbits.

Chemoprophylaxis for pulmonary aspergillosis during intensive chemotherapy.
Three children who developed pulmonary aspergillosis while being treated for leukaemia or non-Hodgkin's lymphoma. Each child continued with intensive myelosuppressive chemotherapy regimens during the infection and each was successfully treated with antifungal prophylaxis based on itraconazole by mouth. Amphotericin B was also given during periods of severe neutropenia. No reactivation of the fungal infection was seen.

Prediction of systemic fungal infection in allogeneic marrow recipients: impact of amphotericin prophylaxis in high-risk patients.
To identify risk factors that might predict for systemic fungal infections in marrow transplant recipients within the first 100 days and to assess the efficacy of low-dose amphotericin B used as prophylaxis for candidemia and infection with invasive Aspergillus species in patients at risk.. A retrospective analysis of transplant outcomes for 331 allogeneic marrow recipients transplanted between 1983 and 1989 was performed to identify patients who might be at increased risk of fungal infection. Factors analyzed included disease, remission status, transplant regimen, graft-versus-host disease (GVHD) prophylaxis, duration of neutropenia, and development of GVHD. A trial of low-dose amphotericin (5 to 10 mg/d) begun on day +1 and continuing for 2 to 3 months posttransplant was begun in 1987 to evaluate its utility in reducing systemic mycoses.. There were 18 episodes of candidemia and 18 systemic mycoses documented by blood or tissue culture or by biopsy. The initiation of high-dose (0.5 to 1 mg/kg/d) corticosteroids early as a component of GVHD prophylaxis in 1986 was identified as the most important risk factor for fungal infections, with a sixfold increase in infections as compared with the previous GVHD regimen (P < .0001); this was despite a significant decrease in the incidence of grade II to IV GVHD (7% v 43%; P = .0001). Low-dose amphotericin B initiated before the start of high-dose corticosteroid GVHD prophylaxis reduced the incidence of fungal infections from 30% to 9% (P = .01) without renal toxicity. Cyclosporine levels were lower in the patients who received amphotericin, leading to an increase in the rate of GVHD to 19% (P = .02). Controlling for GVHD prophylaxis, prolonged neutropenia (P = .00), and grade II to IV GVHD (P = .01) were also identified as risk factors for fungal infection.. Amphotericin B can be used in low doses as prophylaxis for fungal infections early in the posttransplant course. However, cyclosporine doses need to be monitored to maintain target levels.

Rhinocerebral aspergillosis in patients undergoing bone marrow transplantation.
Rhinocerebral aspergillosis (RA) is becoming increasingly common in patients undergoing bone marrow transplantation (BMT). The disease can involve nearly all major head and neck structures, including the nose, paranasal sinuses, and orbits. Intracranial extension of the infection is of major concern, since this is usually a fatal complication. Our study population comprised 423 consecutive BMT patients at Hadassah University Hospital from January 1986 to August 1992. Eight patients (1.9%) developed RA, 5 of whom had underlying hematologic malignancies, and 3 of whom had severe aplastic anemia. Only 2 of the 8 patients responded completely to therapy, with a follow-up of 15 months. It appears that RA is a fatal complication in immunocompromised patients post-BMT. Early diagnosis followed by extensive surgical debridement of necrotic tissue and systemic, as well as topical, antifungal therapy with amphotericin B or its new formulations and the patient's recovery of bone marrow function may improve the outcome of this life-threatening complication.

Treatment of systemic candidiasis in a neutropenic murine model using immunoglobulin G bearing liposomal amphotericin B.
Efficacy of immunoglobulin G (IgG) bearing liposomal amphotericin B (LAMB-IgG), liposomal amphotericin B without IgG (LAMB) or free amphotericin B (fAMB/Fungizone) was investigated in the treatment of systemic candidiasis in a neutropenic mouse model. Treatment with a single dose (0.6 or 0.9 mg amphotericin B per kg body weight) of LAMB-IgG resulted in a significant increase in the survival rate of neutropenic mice infected with 3 x 10(5) cfu of Candida albicans compared to untreated controls, mice injected with IgG, or liposome alone. Survival was also better in neutropenic mice treated with LAMB-IgG than in neutropenic mice treated with the same dose of LAMB or fAMB. Moreover, 65% of all mice survived the infection after treatment with a single dose of 0.6 mg AMB of the LAMB-IgG formulation. Quantitative culture counts of organs showed that both fAMB and LAMB-IgG formulations even at a dose of 0.3 mg AMB/kg, cleared C. albicans from the spleens, livers, and lungs but not from the kidneys. However, a decreased number of C. albicans cells was recovered from the kidneys of mice that survived the infection. Results of the study suggest that LAMB-IgG is more effective than LAMB or fAMB in the therapy of disseminated candidiasis in neutropenic mice.

The toxicity of daily inhaled amphotericin B.
Inhaled amphotericin was administered to 29 patients with prolonged neutropenia and toxicity was analyzed. Treatment consisted of 30 mg of amphotericin B administered by nebulizer once daily via either a hand-held nebulizer or face mask. The mean duration of treatment was 16 days. Toxicity was minimal and patient had significant toxic reaction to the inhaled medication. This study documents that nebulized amphotericin B has less than 10% incidence of severe toxicity with 95% confidence level. Guidelines for future trials and use are suggested.

[Candida infection in the severely burned patient--a successful treatment concept with liposomal amphotericin B].
Candida sepsis is a very serious complication in severely burned patients. This mainly affects patients whose immune system is weakened by illness and/or by drugs. Often diagnosis is difficult because candida sepsis occurs after an initial infection, but therapy is always difficult. Good fungicidal drugs are available, but their side effects limit their effectivity. Two severely burned patients who were suffering from a gram-negative sepsis confirmed by clinical and laboratory data developed candida sepsis. Conventional therapy failed, and both patients suffered from renal failure with constantly high candida-latex-antigen titre. By means of the liposomal encapsulated amphotericin B, which has the same fungicidal effect as amphotericin B, but without its limiting side effects, both, patients could be saved. The kidneys functioned as normal again, the laboratory findings were normal when the patients were discharged.

Penicillium marneffei infection in patients infected with human immunodeficiency virus.
From June 1990 to August 1991, 21 patients infected with the human immunodeficiency virus (HIV) presented with systemic mycosis caused by Penicillium marneffei. Between August 1987 and August 1991, only five patients were observed who had P. marneffei infection but not HIV infection. The clinical presentation included fever, cough, and generalized papular skin lesions. For 11 of these 21 patients, the presumptive diagnosis of P. marneffei infection could be made by microscopic examination of Wright's-stained bone marrow aspirate and/or touch smears of skin specimens obtained by biopsy several days before the results of culture were available. Initial clinical response to treatment with either parenteral amphotericin B or oral itraconazole was favorable in most patients. Epidemiological and clinical evidence suggest that this systemic mycosis is caused by an important opportunistic pathogen and that it should be included in the differential diagnosis of AIDS, at least for countries in areas of endemicity, i.e., Southeast Asia and China.

Epidemiology of nosocomial acquisition of Candida lusitaniae.
Candida species are important nosocomial pathogens; however, little is known about the epidemiology of Candida lusitaniae, an organism frequently resistant to amphotericin B. We evaluated 98 patients admitted to the bone marrow transplant and medical intensive care units of a tertiary-care hospital. Each patient with C. lusitaniae was matched with control patients. Restriction fragment analysis of DNA was used to determine strain relatedness. Seven patients (7.1%) with C. lusitaniae were identified; five acquired C. lusitaniae after admission to the study unit. All isolates were susceptible to amphotericin B. There were no differences between patients and controls with regard to duration of stay in the study unit, antibiotic administration, antifungal therapy, immunosuppressive therapy, catheter use, or underlying disease. Temporal and geographic clustering of five patients with identical strains occurred. No common source was identified. Restriction fragment analysis revealed a total of eight strains, and five patients shared one strain type. These results demonstrate exogenous acquisition of C. lusitaniae. The mechanism of acquisition is probably indirect contact transmission between patients.

Surveillance and treatment of liver transplant recipients for candidiasis and aspergillosis.
Between June 1988 and May 1991 88 orthotopic liver transplants and 1 liver and pancreas transplant were performed at the Liver Transplantation Department of the Ospedale Maggiore of Milan. All the patients underwent mycological surveillance and received antifungal prophylaxis with oral amphotericin B (6000 mg/day) or oral or intravenous fluconazole (200 mg/day) from the time of their transplant. The incidence of Candida colonization was 67%. Fluconazole was superior to oral amphotericin B in the treatment of C. albicans colonization (9/9 vs 6/15), but less effective in the treatment of colonization by other Candida spp. (0/3 vs 3/3). Deep-seated candidiasis developed in 5 patients, caused by C. albicans in 4 cases and C. krusei in 1. C. albicans infection resolved rapidly with fluconazole in 2 subjects, with intravenous amphotericin B alone in 1, and with amphotericin B plus flucytosine in the other. On the contrary, C. krusei infection did not respond to treatment with amphotericin B combined with flucytosine. Aspergillosis was diagnosed in 11 patients, of whom 4 died from invasive aspergillosis, despite 15 and 26 days of amphotericin B treatment in 2. In another patient invasive aspergillosis, diagnosed a few hours before retransplantation, improved with liposomal amphotericin B, but this man died from cytomegalovirus infection one month later. Aspergillosis was eradicated by itraconazole in 4 other patients and by topical amphotericin B in 2 whose infection was localized to surgical wound.

Treatment of cerebral aspergillosis after liver transplantation.
We report the treatment of cerebral aspergillosis with amphotericin B, flucytosine, surgery, and liposomal amphotericin B (L-AmB) after a liver transplant. The patient died 2 months after cessation of antifungal therapy, as a consequence of multiple-system organ failure. The only relevant postmortem finding in the brain was a small, encapsulated abscess containing hyphae. This case indicates that L-AmB is an effective alternative drug for cerebral aspergillosis.

[Cryptococcosis: presentation of 26 cases].
Cryptococcosis is more frequently observed since the appearance of the acquired immunodeficiency syndrome (AIDS). AIDS has modified the clinical and evolutive forms of the disease. This study reviews the changes produced in the infection from the context of AIDS.. The present is a retrospective study (1985-1990) including patients presenting: 1) a positive latex agglutination test (serum or spinal fluid) or 2) a Sabouraud culture positive for cryptococcus. Clinical histories were revised collecting clinical, radiologic, analytic, therapeutic and evolutive data.. Twenty-six patients (21 males) were included in the study. Twenty patients had the human immunodeficiency virus. The clinical picture was: 22 cases with cryptococcal meningitis (13 with hematogenous participation), 3 with pulmonary cryptococcosis and one with disseminated cryptococcosis without meningeal involvement. The patients with AIDS had: greater frequency of positive hemocultures, higher serologic titers and fewer with the meningeal syndrome. The number of T4 lymphocytes was lower than 150 elements/ml in AIDS patients. In 17 patients treatment with amphotericin B and 5-fluorocytosine was administered, 5 received amphotericin B and two fluconazole and two did not receive the above since they had not been diagnosed alive. There were 6 deaths and 10 relapses in 6 AIDS patients and none in the remaining patients.. The incidence of cryptococcosis has increased as a consequence of AIDS. In these patients the disease occurs in advanced stages of immunodeficiency and frequently in disseminated, severe and paucisymptomatic forms. Treatment is usually effective although a maintenance therapy is required to avoid relapse.

Cryptococcal meningitis: outcome in patients with AIDS and patients with neoplastic disease.
A retrospective analysis of 41 patients with cryptococcal meningitis and AIDS or neoplastic disease was done. Patients with AIDS were younger and predominantly male; they had a shorter duration of prior illness, higher initial serum cryptococcal antigen titers, and lower initial cerebrospinal fluid white blood cell counts than those with neoplastic disease. The median overall survival for patients with AIDS was 9 months compared with 2 months for those with neoplastic disease (P = .004). Seventy-eight percent of patients with AIDS and 43% of those with neoplastic disease were cured or improved 6 months after diagnosis (P = .039). Toxicity from amphotericin B and flucytosine was similar for both groups. One patient with AIDS relapsed. Multivariate predictors of survival included headache (P = .007) and an AIDS diagnosis (P = .009). Examination of outcomes for other opportunistic infections associated with AIDS and other immunosuppressive illness may distinguish prognostic features for different patient populations.

[Cryptococcosis in AIDS patients: a study of 19 cases].
We discuss 19 cases of infection due to Cryptococcus neoformans diagnosed in 438 AIDS patients admitted to our center (4%). Fourteen of them showed meningitis confirmed by culture of C. neoformans in CSF. Clinical features were rather unspecific and disorders in CSF parameters were non striking. The diagnostic techniques performed with best results were culture of C. neoformans and antigen determination, especially in serum. Survival probability at one year was 75%. Treatment response was good. Treatment with fluocytosine did not seem to provide additional benefits versus amphotericin alone, neither in respect to clinical evolution nor regarding survival probability at one year. Fluconazole has shown effectiveness in maintenance therapy, being not be possible to evaluate it as an acute phase therapy because the low number of cases in which it was studied. It is advisable to follow a suppressive treatment, having found a 10% relapse rate in patients following therapy and a 50% in those who interrupted it.

Disseminated histoplasmosis in patients receiving low-dose methotrexate therapy for psoriasis.
Low-dose methotrexate sodium therapy used for nonmalignant disease has been associated with a variety of opportunistic infections with pathogens occurring in patients with defective cellular immunity. This article describes the unusual development of disseminated histoplasmosis as a probable complication of immunosuppression resulting from use of methotrexate.. We report the cases of three patients in whom disseminated histoplasmosis developed while receiving low-dose methotrexate therapy for psoriasis. Disease manifestations were unusually severe in two of the three patients. All three cases were disseminated, and two cases resulted in illnesses requiring intensive medical treatment. Each patient responded appropriately to antifungal treatment, although one patient has required long-term suppressive treatment because of persistent Histoplasma antigenuria. These cases illustrate the risk for opportunistic fungal infections in patients receiving low-dose methotrexate therapy for nonmalignant diseases.. Histoplasma should be added to the list of pathogens to be suspected in patients receiving such therapy.

Increase in Candida krusei infection among patients with bone marrow transplantation and neutropenia treated prophylactically with fluconazole.
In early 1990 fluconazole was introduced as a prophylactic antifungal agent after bone marrow transplantation. During the same year Candida krusei emerged as the chief candida pathogen among patients with bone marrow transplants.. To determine whether there was a correlation between the introduction of fluconazole and the increased incidence of C. krusei, we conducted a retrospective study based on the medical, mycologic, and autopsy records of all adult inpatients who had undergone bone marrow transplantation (n = 296) or who had leukemia (n = 167) at the study center during 1989 and 1990.. The 84 patients who received antifungal prophylaxis with fluconazole had a sevenfold greater frequency of C. krusei infection than the 335 patients who did not receive fluconazole (8.3 percent vs. 1.2 percent, P = 0.002), despite having a lower frequency of disseminated C. albicans and C. tropicalis infections (0 vs. 6.0 percent, P = 0.02). Ten of the 11 C. krusei infections were controlled by a combination of amphotericin B and flucytosine. Colonization by C. krusei was found in 40.5 percent of the patients who received fluconazole but in only 16.7 percent of those who did not receive it (P less than 0.0001). Colonization was independently associated with the prophylactic use of both fluconazole (odds ratio, 3.50; P less than 0.001) and norfloxacin (odds ratio, 2.53; P = 0.04). C. krusei was not susceptible to fluconazole in vitro.. In patients at high risk for disseminated candida infections, suppression of bacterial flora and the more common candida pathogens may permit some less pathogenic, but natively resistant candida species, such as C. krusei, to emerge as systemic pathogens.

[Cryptococcal meningitis in AIDS: successful long-term prophylaxis with fluconazole].
A 30-year-old, HIV-positive, man who had been repeatedly treated with amphotericin B for oral thrush, developed headaches, fever up to 38.5 degrees C, dizzy spells with falling tendency, as well as disorder of speech and word finding. Cerebrospinal fluid (CSF) contained 5700/3 cells, of which 90% were encapsulated yeast-fungus. Cryptococcal antigen titres were elevated both in serum (1:256) and CSF (1:1024), providing the diagnosis of cryptococcal meningitis. Intravenous treatment was started with amphotericin B, 0.3 mg/kg daily and flucytosine, 150 mg/kg daily. The clinical, microbiological and serological findings regressed after 4 weeks. After 8 weeks the creatinine concentration rose to 2.5 mg/dl. Because amphotericin B nephrotoxicity was suspected, further intravenous administration was stopped after a cumulative dosage of 2 g. He was placed on a prophylactic dosage of fluconazole, 100 mg by mouth twice daily. The cryptococcal antigen titre had fallen to normal within one year. The prophylactic regimen has been continued now for three years without recurrence or other fungal infection.

Disseminated histoplasmosis in AIDS patients in Maryland.
These patients demonstrate the difficulty in arriving at the diagnosis of disseminated histoplasmosis. The diagnosis in two of the three patients also served as the initial AIDS case-defining opportunistic infection. In each of these patients, the clinical presentations were atypical and in only one patient was a positive exposure history elicited. Recurrent bowel obstruction was the presenting complaint in the first patient and the diagnosis was made only on pathologic exam of the resected small bowel. The second patient's diagnosis was made on biopsy of the colon via colonoscopy. The third patient's diagnosis also eluded an extensive FUO workup; he was diagnosed by bone marrow culture and silver stain of a mediastinal lymph node biopsy, despite serial negative serologic tests for histoplasmosis. The first two patients had significant gastrointestinal disease which is a relatively unusual manifestation for disseminated histoplasmosis. The third patient illustrates the limited diagnostic usefulness of serologic testing in AIDS patients and the continued usefulness of bone marrow analysis in an FUO evaluation. In conclusion, these case presentations demonstrate that disseminated histoplasmosis in patients with HIV infection can present with unusual manifestations, outside of the typical endemic arca, without a positive exposure history or positive serologic test, and may be the initial AIDS case-defining opportunistic infection in these patients. Consequently, a disseminated histoplasmosis should be considered in all AIDS patients with perplexing clinical presentations.

Successful treatment of hepatosplenic candidiasis with a liposomal amphotericin B preparation.
The case of a granulocytopenic patient with acute undifferentiated leukaemia and hepatosplenic candidiasis who was refractory to conventional deoxycholate amphotericin B (AmpB) and 5-flucytosine therapy is reported. He experienced severe AmpB-related side-effects, and was subsequently successfully treated with a pharmaceutical preparation of AmpB (5.7 g) entrapped in sonicated liposomes, composed of lecithin, cholesterol and stearylamine in a molar ratio of 4:3:1. Three months later, during maintenance chemotherapy, liposomal AmpB (5.1 g) was reinstituted due to the finding of biopsies positive for Candida albicans at bronchoscopy. After healing of the patient's fungal infection a left upper lobe resection was performed, which showed advanced fibrosis with signs of inflammation, but no evidence of fungal disease. Since no acute side-effects and only moderate hypokalaemia were observed, it appears that liposomal AmpB is superior to conventional AmpB treatment in granulocytopenic patients with hepatosplenic candidiasis and unbearable therapy-related side-effects.

Optimal therapy of cryptococcosis in patients with the acquired immunodeficiency syndrome.
Although amphotericin B (AB) is the primary therapeutic agent for cryptococcosis complicating the acquired immunodeficiency syndrome (AIDS), the total dose administered is extremely variable, and the end point of therapy has not been well defined. Since these patients require life-long suppressive therapy following the primary therapy, the definition of treatment "end point" becomes crucial. To delineate more effective treatment approaches, we reviewed the medical records of 48 patients with cryptococcosis complicating AIDS. Fever (81%) and headache (77%) were the predominant symptoms. A clinical response to AB (defervescence and resolution of symptoms) was noted in 46% of the febrile patients. The cumulative AB dose administered to the time of clinical response was variable (0.1-1.76 g), but was noted early in the majority of the patients (less than 0.4 g). Repeat fungal cultures from the initial positive site for Cryptococcus neoformans (CN), obtained after observation of the clinical response, were negative in 7/7 patients. Nosocomial bacterial infections were quite common and often complicated intravenous AB therapy. Bacteremias were documented in 10/14 febrile episodes occurring during AB therapy in the 22 patients with an initial clinical response. Bacteremias were identified in 6/21 patients who failed to defervesce with AB therapy. Staphylococcus aureus (N = 9) and Salmonella species (N = 2) were the most common pathogens causing bacteremia. An algorithm for the treatment of cryptococcosis complicating AIDS may shorten the duration of primary intravenous AB therapy. This might reduce secondary infectious complications and the costs of hospitalization.

Opportunistic infections of the esophagus not responding to oral systemic antifungals in patients with AIDS: their frequency and treatment.
To determine the spectrum of esophageal disease responsible for dysphagia/odynophagia in AIDS patients not responding to current oral antifungals, we studied 49 consecutive patients whose esophageal symptoms failed to improve after a minimum of 3 wk of therapy with oral ketoconazole or fluconazole. An esophageal candidiasis resistant to oral antifungals was the most frequent disease found (22 single infections and four mixed with viruses). Viral esophagitis was identified in 13 cases (eight herpes simplex virus and five cytomegalovirus), and an esophagitis of unknown origin was documented in two patients. Other causes of symptoms included peptic esophagitis (four cases), esophageal stenosis (two cases), and Kaposi's sarcoma of the esophagus (one patient). Most patients with esophageal opportunistic infection experienced prompt relief of symptoms and complete endoscopic resolution on the specific antifungal (amphotericin B or fluconazole iv) or antiviral (acyclovir or gancyclovir iv) therapy, with the exception of those with concomitant fungal and viral infection who responded poorly to treatment. We conclude that most AIDS patients with dysphagia/odynophagia who do not respond to oral antifungals have an opportunistic infection of the esophagus. Nevertheless, specific antifungal or antiviral therapy is worthwhile, because it will eradicate, at least temporarily, the causative pathogens in most such patients.

Alternaria infection in a patient receiving chemotherapy for lymphoma.
A 60-year-old man receiving chemotherapy for an intermediate-grade non-Hodgkin's lymphoma developed multiple papuloerythematous cutaneous lesions. Alternaria alternata was cultured from the lesions, and hyphae were seen in biopsy specimens. This is an unusual infection, without a well-established treatment, in patients with lymphoma. The use of amphotericin B resulted in cure.

Fatal mucormycosis presenting as an appendiceal mass with metastatic spread to the liver during chemotherapy-induced granulocytopenia.
Opportunistic fungal infections occur with increasing frequency during chemotherapy induced granulocytopenia. A 27-year-old woman developed mucormycosis in the ileocecal region with fatal dissemination to the liver while receiving consolidation therapy for acute T-lymphoblastic leukemia. The infection occurred during a period of decreased colonization resistance in the intestinal tract. Early symptoms were high fever unresponsive to broad spectrum antibiotics, severe pain in the right lower abdominal quadrant and diarrhoea. This was followed by an infiltrate in the right abdomen, ileus, and icterus. Diagnosis was established in the living patient by thin needle aspiration from affected liver tissue. Giemsa's stain and fungal cultures revealed Mucor indicus. The fatal outcome of disseminated mucormycosis justifies a high index of suspicion and a maximal (invasive) diagnostic effort as localised infections might be cured by resection and amphotericin B.

[Fatal cerebral and pulmonary aspergillosis in acute leukemia in a child].
Immediately after induction therapy for acute lymphoblastic leukemia, a 2 1/2-year-old child developed invasive pulmonary aspergillosis revealed by pneumothorax, an unusual manifestation. Despite treatment with amphotericin B, status epilepticus occurred; this manifestation was related to diffuse ischemic cerebral lesions probably caused by cerebral aspergillosis. Outcome was fatal. Early invasive pulmonary aspergillosis is responsible for non-specific pneumonia. Thoracic CT scan and fiberoptic bronchoscopy are informative investigations. At recovery of bone marrow aplasia, the occurrence of hemoptysis and the discovery of excavated lesions on roentgenograms are suggestive of the diagnosis. Cerebral aspergillosis should be routinely considered whenever neurologic symptoms develop in a patient with agranulocytosis, fever, and pneumonia. The prognosis of invasive aspergillosis depends above all on the promptness of treatment; amphotericin B should be given intravenously whenever broad spectrum antimicrobial therapy fails to induce apyrexia in a patient with agranulocytosis.

Torulopsis glabrata fungemia in a diabetic patient.
We have presented a case of a stable diabetic outpatient who had an acute illness that proved to be Torulopsis glabrata fungemia responsive to amphotericin B therapy. Her only apparent additional predisposition was a nonobstructing renal calculus. Fungemia with this organism in an outpatient is most unusual. T glabrata should be an additional consideration in outpatient as well as inpatient illnesses, especially in diabetic women.

First report of chronic meningitis caused by Trichosporon beigelii.
Trichosporon beigelii (Trichosporon cutaneum) was identified as the causative agent of chronic meningitis in a 15-year-old boy with acute lymphocytic leukaemia. After a neutropenic episode following cytostatic treatment and itraconazole therapy as prophylaxis, cerebrospinal fluid (CSF) samples yielded growth of Trichosporon beigelii. Treatment with amphotericin B, flucytosine and high doses of fluconazole was followed by clinical improvement, although CSF pleocytosis remained. The cross-reactivity between Cryptococcus neoformans and Trichosporon beigelii in a cryptococcal antigen latex test was used as a means of diagnosis in CSF and serum samples.

Trichosporon beigelii, an emerging pathogen resistant to amphotericin B.
Trichosporon beigelii caused fatal disseminated infections that were resistant to amphotericin B in two granulocytopenic patients. In vitro susceptibility studies demonstrated that both index strains of T. beigelii were inhibited but not killed by amphotericin B at achievable concentrations in serum. The minimum lethal concentration for both isolates was greater than or equal to 18 micrograms/ml. Five of seven other isolates were found to have a similar pattern of amphotericin B resistance. The fact that the minimum lethal concentration of T. beigelii was many times greater than its MIC was consistent with a resistance pattern of tolerance. We concluded that T. beigelii may be resistant in vitro to amphotericin B and that this in vitro resistance was correlated with refractory, disseminated trichosporonosis in granulocytopenic patients. T. beigelii should be included in the expanding list of amphotericin B-resistant fungi.

Sinus and nasal manifestations of the acquired immunodeficiency syndrome.
The AIDS epidemic has made previously uncommon infectious diseases and tumors commonplace in HIV-infected individuals. In this article we discuss specific cases of various infections and tumors of the sinonasal tract. Several of these diseases may be the presenting signs of HIV-seropositivity and AIDS. As a result, the clinician first to see such patients must be aware of the diagnosis of these diseases and tumors so that proper testing and treatment may ensue.

Histoplasmosis as a cause of pleural effusion in the acquired immunodeficiency syndrome.
Disseminated histoplasmosis is an increasingly important opportunistic infection in patients with the acquired immunodeficiency syndrome (AIDS). We report the first case of histoplasmosis as a cause of pleural effusion in a patient with AIDS. Recognition of the typical intracellular yeast on a Wright-Giemsa stained smear of the pleural fluid cells allowed prompt initiation of amphotericin B.

Experience with itraconazole in cryptococcosis and aspergillosis.
Cryptococcosis and aspergillosis in immunocompromised patients are extremely difficult clinical conditions to manage and treatment with available antifungal drugs often fails. Itraconazole, R-51211, Janssen Pharmaceutica, a new orally absorbed triazole, is a possible alternative drug which is potentially effective and nontoxic. Preliminary experience with 28 patients, eight with cryptococcosis and 20 with aspergillosis, is reported. Of these patients, 16 were immunocompromised (seven with the acquired immune-deficiency syndrome (AIDS), five heart transplant recipients and four with leukaemia or lymphoma). Overall, results of treatment were good (18 in remission, four markedly improved, four moderately improved and two failed). Prevention of relapses of cryptococcosis was obtained in all patients with AIDS on long-term itraconazole monotherapy (3 mg/kg). Treatment of invasive aspergillosis required a higher dosage (about 5 mg/kg) and prolonged administration. Besides its efficacy this antifungal agent allowed outpatient management.

Prevention of amphotericin-B-induced nephrotoxicity by loading with sodium chloride: a report of 1291 days of treatment with amphotericin B without renal failure.
An open, prospective study was performed to evaluate the clinical usefulness of sodium chloride loading for prevention of amphotericin-B-induced nephrotoxicity in 37 patients requiring 44 courses of amphotericin B treatment. The median duration of the treatment course was 22 days (range, 9-136 days), and mean cumulative dose per patient was 1117 mg (range, 231-7831 mg). During amphotericin B treatment, all patients received 50 to 100 ml of 10% sodium chloride (85 to 171 mmol NaCl) via an intravenous line for prevention of amphotericin-B-induced nephrotoxicity evaluated by serum creatinine levels. Using this regimen, none of the patients developed significant nephrotoxicity (increase in serum creatinine of more than twice baseline level, or serum creatinine level greater than or equal to 2.0 mg/dl, respectively) despite the co-administration of other potentially nephrotoxic drugs. It was not necessary to discontinue treatment with amphotericin B in any of the patients. There were no side effects due to sodium chloride loading. Our results demonstrate that sodium chloride loading is useful for the prevention of amphotericin-B-induced nephrotoxicity.

A new presentation of disseminated histoplasmosis in a homosexual man with AIDS.
The clinical and histopathological features and the therapeutic response of a pustular eruption occurring in a homosexual man with Acquired Immune Deficiency Syndrome (AIDS) is reported. The rare cutaneous presentation consisted of mostly circumscribed, tender, tense pustules, associated with erythema, confined to the face and neck. Biopsy of these lesions revealed intracellular round to oval bodies surrounded by a clear space, consistent with Histoplasma capsulatum. Prompt resolution was observed after initiation of amphotericin B therapy. Clinicians are alerted to the occurrence of exotic presentations of this entity and emphasis is given to the need for skin biopsy and culture to avoid delay in diagnosis and failure to initiate appropriate therapy.

Candida antigen latex test for detection of invasive candidiasis in immunocompromised patients.
Candida antigen latex agglutination testing was performed twice weekly during 217 admissions of 200 patients undergoing intensive chemotherapy alone or supported by autologous or allogeneic bone marrow transplantation. Eleven patients developed invasive candidiasis, three of whom survived; 6 (54.5%) of the 11 had positive Candida antigens. In 206 admissions, invasive candidiasis could not be documented. Of the 60 patients who died, 41 underwent autopsy examination, and 29 (71%) had positive Candida antigens. The latex test was also positive in 30 (20.5%) of the survivors and 10 (53%) of the unautopsied patients. Serum creatinine levels were greater than 2 mg/dL in 61% and 13% of patients with positive and negative Candida antigens, respectively (P less than .0001). For patients in whom the presence or absence of invasive candidiasis could be unequivocally demonstrated, the sensitivity, specificity, and positive and negative predictive values of the latex test at a titer of 1:4 were 54.5%, 29%, 17%, and 70.5%, respectively, suggesting that the latex test should not be used to diagnose invasive candidiasis in immunocompromised patients.

Histoplasma capsulatum polysaccharide antigen detection in diagnosis and management of disseminated histoplasmosis in patients with acquired immunodeficiency syndrome.
Disseminated histoplasmosis is a serious and often rapidly progressive, opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS), supporting the importance of rapid diagnostic tests. We investigated Histoplasma capsulatum polysaccharide antigen (HPA) detection, a promising new method for rapid diagnosis of histoplasmosis.. Sixty-one cases of disseminated histoplasmosis in patients with AIDS form the basis of this report. Control cases were patients with AIDS who had other opportunistic infections and whose cultures were negative for H. capsulatum. A slightly modified radioimmunoassay procedure was used to measure the levels of HPA in urine and blood specimens.. High levels of HPA were detected in the urine of 59 of 61 (96.7%) and the blood of 37 of 47 (78.7%) patients with AIDS complicated by disseminated histoplasmosis. Treatment with amphotericin B reduced levels of HPA in the urine in 19 of 21 (90.5%) and the serum of all 10 patients tested. HPA levels increased in the urine in all eight and in the serum in all five patients with culture-proven relapse.. In conclusion, HPA detection offers a rapid method for diagnosing disseminated histoplasmosis. Additional experience is required to establish the role of this test in monitoring the effects of treatment and in identifying relapse in patients with AIDS.

Long-term amphotericin B therapy for disseminated histoplasmosis in patients with the acquired immunodeficiency syndrome (AIDS).
To assess the efficacy and toxicity of long-term maintenance amphotericin B therapy in preventing relapses after treatment in patients with the acquired immunodeficiency syndrome (AIDS) and disseminated histoplasmosis.. Open, nonrandomized pilot study.. Three private, university-affiliated community hospitals.. We studied 22 consecutive patients with disseminated histoplasmosis and human immunodeficiency virus (HIV) infection. Sixteen patients completed the study, 5 patients died before completing the initial intensive phase of treatment, and 1 patient received a different treatment regimen.. Seven patients were treated with an initial intensive course of 1000 mg of amphotericin B, followed by weekly infusions of 50 to 80 mg until a cumulative dose of 2000 mg was attained; biweekly infusions of 50 to 80 mg were then continued indefinitely. Nine patients received an initial amphotericin B course of 2000 mg followed by weekly infusions of 80 mg.. Of the 7 patients in the 1000-mg intensive regimen group, 6 patients have survived without clinical or laboratory evidence of a histoplasmosis relapse, and 1 died of unrelated causes. Of the 9 patients in the 2000-mg intensive regimen group, 7 patients have survived, 1 patient died of a histoplasmosis relapse, and 1 patient died of other causes. Thus, 13 of 14 patients (93%) who did not die of other causes remained relapse-free. The median follow-up period was 14 months (range, 2 to 23 months). No apparent differences in outcome were observed between patients treated with weekly maintenance regimens and those treated with biweekly maintenance regimens. Sixty-three percent of patients developed intravascular device-related complications.. Long-term, intermittent maintenance amphotericin B therapy in HIV-infected patients with disseminated histoplasmosis is well tolerated and is highly effective in suppressing relapses after treatment.

Cryptococcosis in AIDS patients: observations concerning CNS involvement.
The clinical course and response to therapy of seven patients with cryptococcosis and AIDS were reviewed. One patient was still in the primary stage of cryptococcosis in AIDS, i.e. the stage that is characterized by the sole cultural detection of Cryptococcus neoformans in the respiratory tract. The other six patients were in the secondary stage, where C. neoformans can be detected from the cerebrospinal fluid (CSF), blood, urine, faeces and other body sites. The main presenting features (headache, fever, nausea) were due to central nervous system involvement, although meningism and mental changes were rarely present, and CSF changes were very subtle. Treatment with amphotericin B and flucytosine was very effective, there being no more growth of fungi in cultures in most cases. Adverse reactions to the drugs used occurred frequently and consisted mainly of anaemia, hepatosis and fever. Diagnosis in the primary stage of cryptococcosis may improve the prognosis.

Treatment of invasive Aspergillus sinusitis with liposomal-amphotericin B.
Invasive sinonasal aspergillosis is a severe and frequently fatal infection in immunosuppressed patients with hematologic malignancies. Seven patients with sinonasal aspergillosis who failed to respond to conventional amphotericin B (AmpB) were treated with liposomal AmpB (L-AmpB).AmpB was incorporated into multilamellar vesicles consisting of dimyristoyl phosphatidyl-choline and dimyristoyl phosphatidylglycerol in a 7:3 molar ratio. Five patients had underlying hematologic malignancies, one patient had aplastic anemia, and one patient had no underlying disease. All patients had biopsy-proven invasive Aspergillus sinusitis, and had failed conventional antifungal therapy including AmpB. Five patients were cured and two did not respond to treatment. Fever and chills were infrequent and, when they occurred, mild, and responded well to conventional management. No severe renal or central nervous system toxicity was observed. L-AmpB is effective and less toxic than conventional AmpB in the treatment of invasive Aspergillus sinusitis.

Candida infection in massively burned patients.
Immunosuppressed burned patients receiving antibiotics for suppression of bacterial infection are ideal hosts for opportunistic fungi. Massive excision of burns with autograft and homograft coverage has radically changed the course of disease. Three hundred ninety-three patients were admitted to the Shriners Burns Institute, of whom 125 patients had fungus cultured during their hospitalization and 42 patients subsequently developed involvement of three or more organs. Twenty-one of the 42 patients developed Candida septicemia requiring amphotericin B or flucytosine therapy. The mean third-degree burn in patients with Candida septicemia was 65% total body surface area compared to three-organ involvement/no clinical sepsis at 38% mean third-degree burn. Patients developing candidemia did so during the first week postburn and 7 days after excision therapy. It is hypothesized that massive burns with immunosuppression are further suppressed by repeated surgical intervention, anesthesia, and perioperative use of broad-spectrum antibiotics, further predisposing these patients to early development of Candida septicemia. With early recognition of burn wound invasion by routine biopsies, wound swabs, and early amphotericin therapy, the mortality has been reduced to 14% compared to 60-90% reported in other series.

Successful treatment of disseminated Trichosporon beigelii (cutaneum) infection with associated splenic involvement.
Fungemia caused by Trichosporon beigelii (cutaneum) has been recently recognized as a fatal infection afflicting immunocompromised patients. The authors report the case of a leukemic patient who developed splenic infection from disseminated T. beigelii. Treatment with amphotericin B, 5-fluorocytosine, and splenectomy proved successful. The etiology of disseminated T. beigelii infection, visceral seeding, and combination antifungal therapy also are discussed.
