Fatal hemorrhagic pneumonia caused by infection due to Kytococcus sedentarius--a pathogen or passenger?
A 55-year old man developed a hemorrhagic pneumonia, likely due to infection with Kytococcus sedentarius during neutropenia following induction chemotherapy for acute myeloid leukemia. Severe mucosal barrier injury and the selective pressure of broad-spectrum antibiotics probably made it possible for this normally harmless commensal to penetrate the gut, spread through the blood stream, and invade the lungs.

Acyclovir prophylaxis and fever during remission-induction therapy of patients with acute myeloid leukemia: a randomized, double-blind, placebo-controlled trial.
A randomized, double-blind, placebo-controlled trial was performed to estimate the preventive effect of the antiherpetic drug acyclovir on fever, incidence of bacteremia, use of antibiotics, and presentation of infections in patients with acute myeloid leukemia (AML).. Ninety herpes simplex virus (HSV)-seropositive patients aged 18 to 84 years were included. Forty-five patients received acyclovir (800 mg by mouth daily) and 45 placebo. The patients were examined daily for 28 days from the initiation of remission-induction chemotherapy.. Fever developed in all patients in both groups. Acyclovir prophylaxis postponed the development of an oral temperature > or = 38.0 degrees C by 3 days (95% confidence interval [CI], 1 to 4 days; P = .03) and the initiation of antibacterial treatment by 3 days (95% CI, 1 to 5 days; P = .008). The duration of fever, use of antibacterial treatment, incidence of bacteremia, and need for systemic antifungal therapy were not affected by acyclovir prophylaxis. At fever development, acyclovir prophylaxis affected the incidence and localization pattern of oral ulcers. Thus, in the acyclovir group, the number of nonfungal oral infections was reduced (relative risk, 0.45 [95% CI, 0.24 to 0.85]) and mainly located on the soft palate (relative risk, 2.49 [95% CI, 1.19 to 5.22]).. Acyclovir prophylaxis has an impact on fever development, but not on the duration of fever or the need for antibiotics. It does not reduce the incidence of bacteremia, but the presentation of acute oral infections is changed.

Prevention of herpes simplex virus (HSV) infection in recipients of HLA-matched T-lymphocyte-depleted bone marrow allografts.
The occurrence of HSV infection and the effect of prophylaxis with oral acyclovir were evaluated prospectively in 34 consecutive patients undergoing bone marrow transplantation (BMT). All allogeneic BMT procedures involved T-lymphocyte depletion for prevention of graft-vs.-host disease (GVHD). Five HSV-seronegative patients did not receive acyclovir, and they did not develop HSV infection. Oral acyclovir was administered to 15 HSV-seropositive BMT recipients; 14 untreated HSV-seropositive BMT recipients served as a control group. The adult dose of acyclovir was 400 mg three times a day on Days -6 to +14 and 200 mg three times a day on Days +15 to +90. Children received 500 mg/m2 per day divided into three equal doses on Days -6 to +14 and 250 mg/m2 per day again divided into three on Days +15 to +90. In the group on prophylaxis, only one developed HSV infection during the time prior to engraftment. In the reference group, 12 of 14 (85.7%) developed oral HSV infection within 0 to 16 days (median 11 days) after the transplantation. Time for engraftment (duration of neutropenia) was shorter in patients receiving acyclovir. After engraftment, HSV infection was not observed during administration or following discontinuation of acyclovir on Day 90, but occurred in three patients in whom acyclovir was discontinued on Days 25, 35 and 40 after BMT. In the untreated group, two patients had recurrence of HSV infection on Days 40 to 60, and one had two infectious episodes. GVHD occurred in only two recipients, neither of whom had HSV infection. We conclude that the incidence of HSV infection during the period until engraftment in recipients of T-lymphocyte-depleted BMT is high, similar to that reported by others in recipients of whole BMT. Relatively low-dose oral acyclovir administered for 90 days can effectively prevent HSV infections in previously HSV-seropositive BMT recipients and may also shorten the period until engraftment.

A long-term prospective clinical study of orofacial herpes simplex virus infection in acute leukemia.
Orofacial mucocutaneous infections resulting from herpes simplex virus (HSV) were detected in 40% of patients with acute leukemia. Of the 34 separate episodes, oral mucosal sites were involved in 22 cases. Evidence to support dissemination of HSV was found in 3 patients on 4 separate occasions. The relationship of neutrophil levels to the onset and resolution of lesions is examined. The value of acyclovir for treatment of these HSV-induced lesions is reported, and the question of administering this agent for routine prophylaxis against HSV in these patients is addressed.

Topical Treatment of Acyclovir-Resistant Herpes Simplex Virus Stomatitis after Allogeneic Hematopoietic Cell Transplantation.
We report on patients who developed severe acyclovir-resistant (ACVr) herpes simplex virus 1 (HSV-1) stomatitis after allogeneic hematopoietic cell transplantation (HCT).. HCT patients suffering from HSV-1 stomatitis without response after 1 week of high-dose acyclovir (ACV) were tested for ACV resistance. Patients with proven ACV resistance were treated either topically with cidofovir solution and gel or with topical foscavir cream or with intravenous foscavir.. Among 214 consecutive HCT patients, 6 developed severe ACVr HSV-1 stomatitis (WHO grade III n = 1, WHO grade IV n = 5). All 6 patients suffered from relapse of acute myeloid leukemia (AML) after HCT. ACVr stomatitis was treated topically with first-line (n = 4) or second-line (n = 2) cidofovir. Topical foscavir cream was applied as first-line (n = 1) or second-line (n = 1) therapy. Intravenous foscavir was used in 3 patients (first-line therapy, n = 1; second-line therapy, n = 2). Complete remission was reached by topical cidofovir (n = 3), topical foscavir (n = 1), and intravenous foscavir (n = 1), respectively. Five of the 6 patients died due to progression of leukemia. Only 1 patient survived.. ACVr HSV-1 stomatitis is a severe complication in AML patients relapsing after HCT. It reflects the seriously impaired general condition of these patients. This analysis shows that topical treatment with cidofovir or foscavir might be a sufficient first-line therapy approach in ACVr HSV-1 stomatitis. It might serve as a less toxic alternative to intravenous foscavir.

Visceral disseminated varicella zoster virus infection with brachial plexus neuritis detected by fluorodeoxyglucose positron emission tomography and computed tomography.
Varicella zoster virus (VZV) infection sometimes result in visceral disseminated VZV infection (VD-VZV), which is a fulminant disease featured by abdominal pain and the absence of skin lesions, particularly occurs in the immunosuppressive patients. Brachial plexus neuritis (BPN) is another rare type of VZV infection usually appears without blisters. Few diagnostic images of both VD-VZV and BPN-VZV have been reported. A 25-year-old woman receiving allogeneic hematopoietic stem cell transplantation (HSCT) for acute myeloid leukemia. Unexplained severe pain in the left upper extremity followed by severe stomachache, liver dysfunction and unconsciousness appeared on day 344 post-HSCT. Computed tomography (CT) showed left brachial plexus hypertrophy and edematous changes to the hepatoduodenal ligament, fluorodeoxyglucose positron emission tomography (FDG-PET) showed increased uptake in both lesions. Intravenous acyclovir therapy was started and successfully resolved all symptoms. Several days later, blisters appeared all over the body and positive VZV DNA from blood using polymerase chain reaction test was obtained. FDG-PET and CT may offer supportive findings for detecting or diagnosing blister-less VZV infectious diseases.

Acute isolated appendicitis due to Aspergillus carneus in a neutropenic child with acute myeloid leukemia.
We describe a case of isolated acute appendicitis due to Aspergillus carneus in a neutropenic child with acute myeloid leukemia (AML) treated according to the AIEOP AML 2002/01 protocol. Despite prophylaxis with acyclovir, ciprofloxacin and fluconazole administered during the neutropenic phase, 16 days after the end of chemotherapy the child developed fever without identified infective foci, which prompted a therapy shift to meropenem and liposomial amphotericin B. After five days of persisting fever he developed ingravescent abdominal lower right quadrant pain. Abdominal ultrasound was consistent with acute appendicitis and he underwent appendectomy with prompt defervescence. PAS+ fungal elements were found at histopathology examination of the resected vermiform appendix, and galactomannan was low positive. A. carneus, a rare species of Aspergillus formerly placed in section Flavipedes and recently considered a member of section Terrei, was identified in the specimen. Treatment with voriconazole was promptly started with success. No other site of Aspergillus localization was detected. Appendicitis is rarely caused by fungal organisms and isolated intestinal aspergillosis without pulmonary infection is unusual. To our knowledge, this is the first report of infection due to A. carneus in a child and in a primary gastrointestinal infection.

Prognostic impact of viral reactivations in acute myeloid leukemia patients undergoing allogeneic stem cell transplantation in first complete response.
Cytomegalovirus (CMV) serological status of donor and recipient as well as CMV reactivation have been associated with a lower risk of relapse in acute myeloid leukemia (AML) patients after allogeneic stem cell transplantation (alloSCT). Since immunosuppression following transplant allows resurgence of many other viruses, we retrospectively evaluated the impact of viral reactivations on relapse and survival in a cohort of 136 AML patients undergoing alloSCT in first remission from sibling (68%) or unrelated (32%) donors. Myeloablative and reduced-intensity conditioning regimen were given to 71 and 65 patients, respectively. Including CMV reactivations, at least 1 viral reactivation was recorded in 76 patients. Viral reactivations were associated with a lower risk of relapse (adjusted HR 0.14; 95% CI 0.07-0.30; P < 0.01), better disease-free survival (aHR 0.29; 95% CI 0.16-0.54; P < 0.01) but higher non relapse mortality. This translated into a better overall survival (aHR 0.44; 95%CI 0.25-0.77; P < 0.01) in patients who experienced viral reactivation. Thus, viral reactivations, including but not limited to CMV reactivation, are associated with a better outcome particularly with regard to the risk of relapse in AML patients undergoing alloSCT. New guidelines regarding the choice of donor according to the CMV serostatus are needed.

Heterogeneity and evolution of thymidine kinase and DNA polymerase mutants of herpes simplex virus type 1: implications for antiviral therapy.
Infections caused by acyclovir-resistant isolates of herpes simplex virus (HSV) after hematopoietic stem cell transplantation (HSCT) are an emerging concern. An understanding of the evolutionary aspects of HSV infection is crucial to the design of effective therapeutic and control strategies.. Eight sequential HSV-1 isolates were recovered from an HSCT patient who suffered from recurrent herpetic gingivostomatitis and was treated alternatively with acyclovir, ganciclovir, and foscavir. The diverse spectra and temporal changes of HSV drug resistance were determined phenotypically (drug-resistance profiling) and genotypically (sequencing of the viral thymidine kinase and DNA polymerase genes).. Analysis of 60 clones recovered from the different isolates demonstrated that most of these isolates were heterogeneous mixtures of variants, indicating the simultaneous infection with different drug-resistant viruses. The phenotype/genotype of several clones associated with resistance to acyclovir and/or foscavir were identified. Two novel mutations (E798K and I922T) in the viral DNA polymerase could be linked to drug resistance.. The heterogeneity within the viral populations and the temporal changes of drug-resistant viruses found in this HSCT recipient were remarkable, showing a rapid evolution of HSV-1. Drug-resistance surveillance is highly recommended among immunocompromised patients to manage the clinical syndrome and to avoid the emergence of multidrug-resistant isolates.

Disseminated varicella presenting as acute abdominal pain nine days before the appearance of the rash.
We report a patient presenting with severe epigastric pain and diffuse abdominal tenderness, with negative imaging and endoscopic evaluation. During hospitalization, the patient developed confusion, seizures, pneumonia, anemia and thrombocytopenia. A hemorrhagic rash appeared on day nine of admission, with serology and skin biopsy confirming a diagnosis of hemorrhagic varicella.

Atypical varicella zoster infection associated with hemophagocytic lymphohistiocytosis.
Two adolescents, on immunosuppressive therapy for graft-versus-host disease, developed hemophagocytic lymphohistiocytosis (HLH) after varicella zoster virus (VZV) reactivation. In the absence of dermatome restricted characteristic skin lesions, VZV reactivation was not immediately recognized and treatment with acyclovir was delayed. The first patient developed optical neuritis and died 2 months after the VZV episode due to massive intracranial hemorrhage. The second patient presented with severe abdominal pain and pancreatitis, followed by atypical skin eruptions, which prompted a faster diagnosis. Both patients recovered from their HLH, the first patient being successfully treated with immunosuppressive agents and the second with VZV treatment only. These two cases demonstrate the difficulties in recognizing VZV reactivation, and in order to start adequate and timely treatment, the need to consider VZV as a possible cause of HLH in severely immunocompromised patients.

Visceral varicella zoster virus (VZV) after allogeneic hematopoietic stem cell transplant (HSCT) in pediatric patients with chronic graft-versus-host disease (cGVHD).
Reactivation of latent varicella zoster virus is one infectious complication associated with the extensive immunosuppression necessary for hematopoietic stem cell transplant. Most cases are limited to skin and mortality is low. Isolated visceral zoster is rare, presenting with ileus/abdominal pain, hepatitis, and/or hyponatremia. We present 2 cases of visceral varicella zoster virus in adolescents with chronic graft-versus-host disease after hematopoietic stem cell transplant. Both presented with elevated liver enzymes, severe abdominal pain, and hyponatremia but lacked cutaneous involvement. Both received high-dose acyclovir and showed improvement, but eventually expired from hepatic failure. The diagnosis of visceral zoster can be difficult especially without cutaneous manifestations. Vigilance is necessary in patients with chronic graft-versus-host disease, abdominal pain, and/or hepatitis and antiviral therapy should be initiated promptly.

Herpes zoster in children with cancer.
The aim of this study was to determine the incidence and outcome of herpes zoster hospitalised children with cancer in Kota Baru. It was a retrospective review from January 1994 to December 1998. The diagnosis of herpes zoster was a clinical one. Herpes zoster was diagnosed in 10 of 188 (5%) children with malignancy. The most common malignancy was leukaemia. Nine children were treated with acyclovir. No child developed visceral dissemination and there were no deaths.

Herpetic geometric glossitis in a pediatric patient with acute myelogenous leukemia.
Herpetic geometric glossitis, a recently described form of lingual herpes simplex virus type 1 (HSV-1) infection, has been reported in 6 human immunodeficiency virus (HIV) patients and 1 cardiac transplant patient who was receiving immunosuppressant therapy. An HIV-seronegative immunocompromised pediatric patient with acute myelogenous leukemia who developed herpetic geometric glossitis is described. Herpetic geometric glossitis can present in both adult and pediatric immunocompromised patients. The symptoms, morphology, laboratory findings and treatment of this infection are summarized. The possible consequences of untreated herpetic glossitis include superinfection and undernourishment. Although previously described patients responded to 1000 mg per day (divided in 5 doses) or oral acyclovir, with complete resolution of fissures, this patient developed herpetic geometric glossitis while receiving acyclovir and required higher doses of oral antiviral therapy (acyclovir, 3000 mg/day divided in 5 doses) to treat his HSV-1 lingual infection. Empiric treatment of an immunocompromised patient who has newly acquired painful tongue fissures or furrows with systemic acyclovir should be considered.

Long-term acyclovir prophylaxis for prevention of varicella zoster virus infection after autologous blood stem cell transplantation in patients with acute leukemia.
Twenty-one adult patients with acute leukemia who underwent autologous blood stem cell transplantation (ABSCT) and who received acyclovir during the first 6 months after transplant to prevent varicella zoster virus (VZV) infection were studied retrospectively to determine the incidence and outcome of VZV infection after ABSCT. The cumulative risk of VZV infection was 32% by 1 year after transplant. No patient developed VZV while on prophylactic acyclovir but five (24%) had localized herpes zoster within 1 month of acyclovir withdrawal. There were no deaths related to VZV infection and only one patient had disseminated disease and post-herpetic neuralgia. These preliminary results suggest that the incidence and outcome of VZV infection after ABSCT largely parallel those reported in marrow transplant patients and that long-term acyclovir prophylaxis delays but does not prevent VZV infection. Prophylaxis of VZV infection after ABSCT requires new therapeutic approaches.

Clinical study of herpes simplex virus infection in leukemia.
Twenty-nine patients with leukemia were observed for the development of and recovery from oral herpes simplex virus (HSV) lesions. In patients with seropositive test results, lymphocyte and monocyte counts may provide a guide to predict the onset of HSV infections and to indicate when to institute acyclovir prophylaxis. When HSV developed, acyclovir was effective in preventing progression of the lesions, which did not resolve until white cell counts had recovered.

Characterisation of acyclovir-resistant and -sensitive clinical herpes simplex virus isolates from an immunocompromised patient.
A detailed study was made of herpes simplex virus type 1 (HSV-1) isolates from an immunocompromised patient whose infection became resistant to acyclovir (ACV) during a prolonged course of oral treatment. Three HSV isolates and 33 virus clones derived from them were characterised. The development of clinical resistance correlated with the emergence of thymidine kinase (TK) defective strains. The ACV-sensitive strains studied contained a small proportion of insensitive virus. The resistant isolate contained 0.6% of TK-positive virus which was sensitive to a relatively low concentration of ACV.

Interstitial pneumonitis in allogeneic bone marrow transplantation: a report from the Japanese BMT Study Group.
One hundred and four patients with acute leukemia treated by allogeneic bone marrow transplantation in Japan were analysed for the incidence of interstitial pneumonitis (IP). Thirty-six (35%) of 104 marrow graft recipients developed IP. Cytomegalovirus (CMV) was the most frequent organism (61%). Using multivariate analysis, remission at transplant (P = 0.0001) and use of cyclosporin A to prevent graft-versus-host disease (P = 0.0363) were found to be significant factors associated with a decreased incidence of IP. For preventing IP, anti-CMV hyperimmune globulin was effective, while interferon and acyclovir were not.

[Bone marrow transplantation in acute leukemia, chronic myeloid leukemia, severe aplastic anemia and stage IV neuroblastoma. Effect of antiviral prevention with anti-CMV-hyperimmunoglobulin and acyclovir].
Bone marrow transplantation was performed between IV/82 and X/85 in 64 patients with acute leukemia (n = 36), chronic myelogenous leukemia (CML; n = 13), severe aplastic anemia (n = 12), and neuroblastoma stage IV (n = 3). Of these patients 57 received allogeneic marrow from HLA-ABCDR identical, MLC-negative sibling donors. Six transplants were performed with syngenic marrow and one with autologous marrow. Of the 64 patients 48 survived 40-1,250 days after transplantation, resulting in a survival rate (SR) of 75% and a survival probability (SP) of 71%. Of the 36 patients suffering from acute leukemia (SR = 64%, SP = 51%), patients with acute myelogenous leukemia (AML) in first complete remission (n = 11; SR = 81%, SP = 76%), as well as patients with acute lymphatic leukemia (ALL) in 1st to 4th complete remission at the time of transplantation (n = 14; SR = 81%, SP = 76%) show a favorable prognosis. A poor survival rate was seen for patients with AML when transplanted in second or partial remission (1/5; SR = 20%), as well as for patients suffering from ALL and transplanted during relapse or partial remission (1/6; SR = 16%). Of 13 patients suffering from CML 12 survived the transplantation free of relapse (SR = 93%, SP = 92%), and one patient died from varicella zoster pneumonia. Of the transplanted patients with severe aplastic anemia, 12 of 13 are surviving with complete hematologic reconstitution; one patient, however, died on day 10 from a sepsis. In our patient group, the SR as well as the SP has been improved through changes in the irradiation protocol concomitant with prophylactic application of anti-CMV hypergammaglobulin, as well as through additional oral medication of Azyklovir. The 41 patients (BMT No. 7-47) with total body irradiation at one time show an SR of 44% and an SP of 41%. The following 46 patients (BMT No. 48-93) have reached an SR of 83% and an SP of 74% under the regimen of fractionated total body irradiation, plus prophylaxis with anti-CMV hypergammaglobulin and Azyklovir. Within this group, no fatal CMV pneumonia was encountered as opposed to six patients lost from CMV pneumonia in the first group.

[Allogeneic bone marrow transplantation after fractionated whole body irradiation. Results at the Kiel transplantation center].
Allogeneic bone marrow transplantations were carried out between March 1983 and July 1985 in 31 patients aged 7 to 45 years (median 18 years). Acute lymphoblastic leukaemia in 1st to 5th remission was present in 8 patients, acute myeloblastic leukaemia in 1st and 2nd remission in 4 patients, chronic myeloid leukaemia, with various remission status, in 6 patients, 3 patients had severe aplastic anaemia and there were single cases of myelodysplasia and immature cell megakaryocytic myelosis. Transplantation was carried out during relapse in 8 patients with either acute myeloid or lymphoblastic leukaemia. Phenotypic HLA-identical mothers (n = 2) as well as genotypic HLA-identical siblings (n = 27), and in two cases HLA-non-identical mothers, served as bone marrow donors. In leukaemia patients the conditioning treatment consisted of fractionated total body irradiation and high dose cyclophosphamide or etoposide. Patients with severe aplastic anaemia received cyclophosphamide (4 X 50 mg/kg) and fractionated total nodal irradiation (total dose 8 Gy). 19 patients (61%) survived 14 to 605 days after bone marrow transplantation. 15 patients (48%) continue to remain in complete remission with Karnofsky indices of greater than or equal to 90%. Causes for death were infection (n = 3), interstitial pneumonia (n = 3), relapse (n = 3) as well as single cases involving acute graft-versus-host-disease, non-engraftment of donor marrow and veno-occlusive disease of the liver.
