The in vitro activities of the ketolide telithromycin and eight other antibiotics were tested against 77 strains of viridans group streptococci isolated from blood samples of neutropenic patients. Thirty-one (40.3%) of the strains were resistant to penicillin G, and 27 (35.1%) were resistant to erythromycin A. Telithromycin (MIC range of < or =0.03 to 1 microg/ml) was the most active antimicrob...

Patients with severe granulocytopenia are more susceptible to severe infections and sepsis. Proinflammatory cytokines such as tumor necrosis factor-alpha (TNF), interleukin-1 alpha (IL-1 alpha), and IL-1 beta play an important role in the pathophysiology of sepsis. The profile of these proinflammatory cytokines after lipopolysaccharide (LPS) challenge in cyclophosphamide-induced neutropenic mic...

BACKGROUND Neutropenia, as a predisposing factor for invasive candidiasis, is defined as a reduction in neutrophil count to less than 1500/mm3. It is a common condition in patients with hematological malignancy and cytostatic chemotherapy. Extensive chemotherapy and prophylaxis with antifungals have increased the resistance of Candida isolates to antifungal drugs. Although, Candida albicans is ...

Candidemia and invasive candidiasis (CIC) is associated with considerable morbidity and mortality, with a paucity of controlled data in neutropenic patients. A systematic review was conducted of available data for the treatment of CIC during neutropenia. A structured OVID search of multiple databases was performed. Data from randomized controlled trials of CIC and of empirical antifungal therap...

Three cases of neutropenic enterocolitis are described. This unusual condition occurs almost exclusively in neutropenic patients and has a fulminating course which is almost invariably fatal without surgical intervention. The lesion is centered on the caecum and hitherto its pathogenesis has been unclear, partly because most studies have been performed on material obtained at necropsy. In these...

BACKGROUND Febrile neutropenia (FN) is a major dose-limiting toxicity of cancer chemotherapy resulting in considerable morbidity, mortality, and cost. This study evaluated the time course of neutropenic events and patterns of supportive care interventions in patients receiving chemotherapy for early-stage breast cancer treated in oncology community practices. METHODS A prospective cohort stud...

Neutropenia is a well-known adverse side-effect of clozapine that can also be seen with other atypical antipsychotics. In this article the authors discuss patient who experienced neutropenia and subsequently redeveloped aripiprazole after short trial. The case illustrates close monitoring caution advisable when trialing patients on any further antipsychotics neutropenic event clozapine.
