amphotericin-b--deoxycholate-drug-combination and Histoplasmosis

Fungal peritonitis (FP) is a rare complication of peritoneal dialysis. We herein describe the second case in Asia of Histoplasma capsulatum peritonitis associated with continuous ambulatory peritoneal dialysis (CAPD).. An 85-year-old woman with end-stage renal disease (ESRD) who had been on CAPD for 3 years and who had a history of 3 prior episodes of peritonitis presented with intermittent abdominal pain for 2 weeks and high-grade fever for 3 days. Elevated white blood cell (WBC) count and rare small oval budding yeasts were found in her peritoneal dialysis (PD) fluid. From this fluid, a white mold colony was observed macroscopically after 7 days of incubation, and numerous large, round with rough-walled tuberculate macroconidia along with small smooth-walled microconidia were observed microscopically upon tease slide preparation, which is consistent with H. capsulatum. The peritoneal dialysis (PD) catheter was then removed, and it also grew H. capsulatum after 20 days of incubation. The patient was switched from CAPD to hemodialysis. The patient was successfully treated with intravenous amphotericin B deoxycholate (AmBD) for 2 weeks, followed by oral itraconazole for 6 months with satisfactory result. The patient remains on hemodialysis and continues to be clinically stable.. H. capsulatum peritonitis is an extremely rare condition that is associated with high morbidity and mortality. Demonstration of small yeasts upon staining of PD fluid, and isolation of slow growing mold in the culture of clinical specimen should provide important clues for diagnosis of H. capsulatum peritonitis. Prompt removal of the PD catheter and empirical treatment with amphotericin B or itraconazole is recommended until the culture results are known.

Histoplasma capsulatum has not typically been associated with sinusitis in either immunocompetent or immunocompromised hosts. We report a case of sinusitis caused by H. capsulatum in a patient with chronic lymphocytic leukemia and discuss the reported cases of this rare clinical manifestation of histoplasmosis in the medical literature.

Systemic fungal infections cause almost 25% of the infection-related deaths in leukaemic patients. Particularly those with prolonged neutropenia are at risk but mycoses also feature in critically ill intensive care patients and in individuals who are treated for solid tumours and AIDS, or who received an organ transplant. The spread of AIDS and the more aggressive cytotoxic chemotherapy in combination with an improved management of haemorrhages and bacterial infections in leukaemic and other cancer patients facilitated the occurrence of these invasive fungal infections. These life-threatening complications remain both difficult to diagnose and to treat and therefore carry a poor prognosis. For many years, the only realistic option to treat systemic infections was amphotericin B, whose administration was known to be associated with numerous adverse effects. Now less toxic formulations of amphotericin have become available for clinical use, as well as several new triazoles that appear to provide an effective and less toxic alternative for the treatment of certain fungal infections.

Histoplasmosis is an invasive mycosis caused by inhalation of the spores of dimorphic fungi Histoplasma capsulatum. The disease manifests in the lung as acute or chronic pulmonary histoplasmosis and in severe cases gets disseminated in multiple organs like skin, adrenal gland, central nervous system, lymph node, liver, spleen, bone marrow, and gastrointestinal tract. It occurs most commonly in immunodeficient patients like HIV-positive patients and transplant recipients, while immunocompetent hosts are affected rarely. In cases of gastrointestinal histoplasmosis, the samples are collected for culture and biopsy should be sent for histopathological examination for definitive diagnosis. We conducted a retrospective study of colonic biopsies performed in the department of gastroenterology in a tertiary care hospital of north India from January 2014 to December 2015. Five cases of colonic histoplasmosis were diagnosed on histopathology out of which 4 patients were from north India while 1 patient was from Myanmar. The patients presented with various complaints, including loose stools, diarrhea, altered bowel habits, and gastrointestinal bleeding. The prognosis is very good after early and aggressive treatment while the disease is fatal if it remains untreated. In our study, 2 patients died within few days of diagnosis due to delay in the diagnosis, dissemination, and associated complications. Other patients were started on amphotericin B deoxycholate and are under follow-up. An early diagnosis of gastrointestinal histoplasmosis is important as appropriate treatment leads to long-term survival while untreated cases are almost fatal.

In patients with acquired immunodeficiency syndrome (AIDS), advanced immunosuppression is associated with atypical presentation of dermatological conditions. Our patient presented with a single crusted plaque over the lower lip and large tender cervical lymphadenopathy. The enzyme-linked immunosorbent assay for human immunodeficiency virus was found to be positive, and his CD4+ lymphocyte cell count was 4 cells/mm

To compare clinical features, diagnosis and therapeutic effect between pulmonary histoplasmosis and progressive disseminated histoplasmosis.
 Methods: A retrospective analysis for 12 cases of hospitalized patients with histoplasmosis, who was admitted in Xiangya Hospital, Central South University during the time from February 2009 to October 2015, was carried out. Four cases of pulmonary histoplasmosis and 8 cases of progressive disseminated histoplasmosis were included. The differences of clinical features, imaging tests, means for diagnosis and prognosis were analyzed between the two types of histoplasmosis.
 Results: The clinical manifestations of pulmonary histoplasmosis were mild, such as dry cough. However, the main clinical symptoms of progressive disseminated histoplasmosis were severe, including recurrence of high fever, superficial lymph node enlargement over the whole body, hepatosplenomegaly, accompanied by cough, abdominal pain, joint pain, skin changes, etc.Laboratory examination showed pancytopenia, abnormal liver function and abnormal coagulation function. One pulmonary case received the operation of left lower lung lobectomy, 3 cases of pulmonary histoplasmosis and 6 cases of progressive disseminated histoplasmosis patients were given deoxycholate amphotericin B, itraconazole, voriconazole or fluconazole for antifungal therapy. One disseminated case discharged from the hospital without treatment after diagnosis of histoplasmosis, and 1 disseminated case combined with severe pneumonia and active tuberculosis died ultimately.
 Conclusion: As a rare fungal infection, histoplasmosis is easily to be misdiagnosed. The diagnostic criteria depends on etiology through bone marrow smear and tissues biopsy. Liposomeal amphotericin B, deoxycholate amphotericin B and itraconazole are recommended to treat infection for histoplasma capsulatum.. 目的：比较肺型与进展播散型组织胞浆菌病的临床特点、诊断及预后差异。 方法：回顾性分析中南大学湘雅医院2009年2月至2015年10月期间收治的组织胞浆菌病住院患者12例，其中肺型4例，进展播散型8例。从临床表现、影像学、确诊途径及预后等方面分析两者之间的差异性。 结果：肺型组织胞浆菌病临床表现轻微，干咳多见。进展播散型患者全身症状明显，极易出现反复高热、全身浅表淋巴结肿大、肝脾肿大，可合并咳嗽、腹痛、关节痛、皮肤改变等。实验室检查示全血细胞减少、肝功能异常、凝血功能异常等。1例肺型患者给予了左下肺切除术，其余3例肺型及6例进展播散型患者分别给予两性霉素B脱氧胆酸盐、伊曲康唑、伏立康唑或氟康唑抗真菌感染治疗，好转出院，1例播散型确诊后暂未治疗即出院，1例播散型因合并重症肺炎及活动性肺结核治疗无效死亡。结论：组织胞浆菌病临床少见，极易漏诊或误诊，依靠骨髓涂片、病理组织切片特殊染色明确病原学是目前确诊的主要依据，推荐两性霉素B脂质体、两性霉素B脱氧胆酸盐及伊曲康唑抗感染治疗。.

Disseminated histoplasmosis is an invasive fungal infection documented in patients with impaired cellular immunity coming from endemic areas (America, Asia, Africa). We report two cases of disseminated histoplasmosis in AIDS patients paradigmatic of the multifaceted nature of the disease, which may be an expression either of an advanced state of immunosuppression or the immune reconstitution inflammatory syndrome (IRIS).

Abstract. Coinfection with tuberculosis in some countries occurs in 8-15% of human immunodeficiency virus (HIV) -infected patients who have histoplasmosis. This coinfection interferes with prompt diagnosis, and treatment is difficult because of drug interactions. We retrospectively reviewed the cases of 14 HIV-infected patients who had concomitant tuberculosis and histoplasmosis. The most frequent clinical manifestations were weight loss (85.7%), asthenia (78.5%), and fever (64.2%). The diagnosis of histoplasmosis was made primarily by histopathology (71.4%), and the diagnosis of tuberculosis was made by means of direct microscopic examination (71.4%). Death occurred in two patients, and relapse of both infections occurred in one patient. Moxifloxacin was substituted for rifampicin in six patients, with good outcomes noted for both infections. The clinical presentation does not readily identify acquired immunodeficiency syndrome (AIDS) patients who have tuberculosis and histoplasmosis. The use of a fluoroquinolone as an alternative agent in place of rifampicin for tuberculosis allows effective therapy with itraconazole for histoplasmosis.

Meningitis is a common evolution in progressive disseminated histoplasmosis in children, and is asymptomatic in many cases. In leukemia, the impaired of the T cells function can predispose to the disseminated form. The attributed mortality rate in this case is 20%-40% and the relapse rate is as high as 50%; therefore, prolonged treatment may be emphasized. We have described a child with acute myeloid leukemia (AML), that developed skin lesions and asymptomatic chronic meningitis, with a good evolution after prolonged treatment with amphotericin B deoxycholate followed by fluconazole.
