Following an outbreak of carbapenem resistant Klebsiella pneumoniae (CRKP) bacteremia among inpatients in the Hemato-oncology and BMT unit, we studied the course of this infection in patients undergoing intensive chemotherapy and SCT. In addition, we conducted a pilot study aimed to eradicate CRKP colonization in the gastrointestinal tract, using oral gentamicin. Adult patients admitted to the BMT unit, identified as CRKP carriers on surveillance rectal cultures, were included in the study. Oral gentamicin at a dose of 80 mg q.i.d. was administered to all identified carriers until eradication. Among 15 colonized patients included in the study, the eradication rate achieved was 66% (10/15); discontinuation of persistent bacteremia occurred in 62.5% (5/8) and nosocomial spread of CRKP carrier state ceased. Administration of intensive chemotherapy and SCT is feasible, although associated with increased risk. Hematological patients in need of intensive chemotherapy/SCT should not be denied the required treatment on the basis of being CRKP carriers. Oral gentamicin treatment for eradication of CRKP from the gastrointestinal reservoir could serve as additional tool in the combat against the nosocomial spread and severe infections caused by this difficult-to-treat organism.

Fluconazole antifungal prophylaxis is standard care in allogeneic hematopoietic stem cell transplant (HSCT) recipients, but this drug lacks anti-Aspergillus activity, the primary cause of invasive fungal infection (IFI) in many transplantation centers. We performed a randomized trial to compare itraconazole vs fluconazole, for prevention of IFIs in patients with acute leukemia (AL) and HSCT recipients. One hundred and ninety-five patients were randomly assigned to either fluconazole or itraconazole antifungal prophylaxis, after stratification into high-risk and low-risk groups. Antifungal prophylaxis was started at the beginning of chemotherapy and continued until resolution of neutropenia, or until amphotericin B treatment was started. IFI occurred in 11 (11%) of itraconazole, and in 12 (12%) fluconazole recipients. Invasive candidiasis (IC) developed in two (2%) itraconazole and one (1%) fluconazole recipients, while invasive aspergillosis (IA) developed in nine (9%) itraconazole and 11(11%) fluconazole recipients. There was no difference in the incidence of total IFI, IC and IA between the two study arms. However, there was a nonsignificant trend towards reduced mortality among patients who developed IA while receiving itraconazole prophylaxis (3/9=33% vs 8/11=73%, P=0.095).Bone Marrow Transplantation (2006) 38, 127–134. doi:10.1038/sj.bmt.1705418; published online 5 June 2006 [ABSTRACT FROM AUTHOR]
