Aztreonam or gentamicin combined with piperacillin as empiric antibiotic therapy during neutropenia of patients with hematologic diseases
Abstract
Fourty-two febrile episodes of 32 patients with hematologic disease during neutropenia were treated with two randomly assigned antibiotic combinations of either piperacillin plus gentamicin or piperacillin plus aztreonam. Eleven of the 22 febrile episodes treated with piperacillin plus gentamicin and 12 of the 20 febrile episodes treated with piperacillin plus aztreonam responded. Addition of cefamandole to non-responders improved the outcome in 2 of the 16 febrile episodes. Mean nadir leucocyte count, age, sex, and underlying disease were not significantly different in both groups. Side effects were tolerable in both groups, although 1 patient treated with piperacillin plus gentamicin showed severe renal impairment. Piperacillin plus aztreonam is as effective as piperacillin plus gentamicin as an empiric antibiotic combination in the treatment of febrile episodes with hematologic disease during neutropenia.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 32 participants or records.
