Benzylpenicillin plus an aminoglycoside versus meropenem in neutropenic lymphoma and leukaemia patients with a suspected bacterial infection: a randomized, controlled trial.
In Norway, initial treatment of febrile neutropenia (FN) has traditionally been benzylpenicillin plus an aminoglycoside. Internationally, FN is often treated with a broad-spectrum ß-lactam antibiotic. We aimed to compare these two regimens in a prospective, randomized, trial in patients with lymphoma or leukaemia with an expected period of neutropenia =7 days, and a suspected bacterial infection.
Adult neutropenic patients with lymphoma or leukaemia, and a suspected bacterial infection, were randomized for treatment with benzylpenicillin plus an aminoglycoside or meropenem. The primary endpoint was clinical success, defined as no modification of antibiotics and clinical stability 72 h after randomization.
Among 322 randomized patients, 297 proved evaluable for analyses. Fifty-nine per cent (95% CI 51%-66%), (87/148) of the patients given benzylpenicillin plus an aminoglycoside were clinically stable, and had no antibiotic modifications 72 h after randomization, compared with 82% (95% CI 75%-87%), (122/149) of the patients given meropenem (p
