Background Treatment of acute myeloid leukemia (AML) comes with a significant risk of life‐threatening infection during periods of prolonged severe neutropenia. We studied the impact of preventive intravenous (IV) antibiotic administration at onset of absolute neutropenia on the incidence and outcome of life‐threatening infections during treatment of childhood AML. Procedures This is a retrospective study on pediatric patients (aged 0–18 years) consecutively diagnosed with de novo AML and treated at a single institution from April 2005 through February 2013. Patients were treated on the Children's Oncology Group (COG) AAML0531 protocol or with a modified United Kingdom Medical Research Council (UK MRC) AML 10 regimen. Pertinent data were extracted from hard copy or electronic chart review. Results A total of 76 chemotherapy phases were analyzed from 29 patients. In each phase reported, preventive antibiotics were initiated when the daily absolute neutrophil count was <500 cells/mcl, before onset of fever. Seven episodes of bacteremia were documented with predominantly coagulase‐negative staphylococci and viridans group streptococci. One infection‐related death occurred, attributed to progressive respiratory failure occurring months after documented candidal pneumonia. Conclusions Initiation of preventive antibiotics at the onset of absolute neutropenia was associated with no mortality from bacteremia. This preventive approach appears feasible and safe.
