Monotherapy or aminoglycoside-containing combinations for empirical antibiotic treatment of febrile neutropenic patients: a meta-analysis.

摘要

We set out to compare the efficacy of antibiotic monotherapy with that of combination therapy including an aminoglycoside for empirical treatment of febrile neutropenic cancer patients. We did a meta-analysis of 29 randomised clinical trials pooling data from 4795 febrile episodes and a subset of 1029 bacteraemic episodes by both fixed and random effects models. Outcome measure was clinical failure of antibiotic treatment, defined as modification of the initially allocated regimen or death during treatment. In febrile episodes, the pooled odds ratio (OR) of clinical failure with monotherapy versus combination therapy was 0.88, with 95% CI from 0.78 to 0.99 by the fixed effects model, and 0.87 with 95% CI from 0.75 to 1.01 by the more conservative random effects model. For bacteraemic episodes, the pooled OR of failure with monotherapy was 0.70 (0.54 to 0.92) by the fixed effects model, and 0.72 (0.54 to 0.95) by the random effects model. We conclude that monotherapy has been as effective as aminoglycoside-containing combinations for empirical treatment of febrile neutropenia.
