Monotherapy with piperacillin/tazobactam versus cefepime as empirical therapy for febrile neutropenia in pediatric cancer patients: a randomized comparison.

The purpose of this study was to compare the efficacy, safety, and cost of piperacillin/tazobactam with cefepime monotherapy in children with febrile neutropenia. A prospective randomized study in children and adolescent with cancer was conducted. Patients were randomly assigned to receive either 80 mg/kg piperacillin/10 mg/kg tazobactam every 6 h (maximum 4.5 g/dose) or cefepime 50 mg/kg every 8 h (maximum 2 g/dose). Treatment modification was defined as all the changes in the empirical antimicrobials after the first 96 h. Overall treatment success was defined as cure of febrile episode with or without modification. Cost of hospitalization, antimicrobial drugs, and supportive therapy were calculated. Fifty febrile neutropenic episodes (25 in the piperacillin/tazobactam group, 25 in the cefepime group) in 27 pediatric cancer patients were evaluated. The groups were comparable in terms of age, gender, body weight, primary diagnosis, disease status, initial neutrophil count, and duration of neutropenia. Microbiologically and clinically documented infection rate was 46%. There was no infection-related mortality in the study period. The treatment success of initial empirical therapy without modification was not different in the 2 groups (56% in piperacillin/tazobactam group and 48% in cefepime group). Anti-anaerobic drugs were added more frequently in the cefepime group. Duration of fever, neutropenia, treatment, and cost of therapy were not different in the treatment groups. Piperacillin/tazobactam monotherapy is as effective as cefepime monotherapy in febrile neutropenia of pediatric cancer patients.
