Cefepime as empirical monotherapy in febrile patients with hematological malignancies and neutropenia: a randomized, single-center phase II trial.

The purpose of this phase II trial was to evaluate the efficacy and safety of cefepime monotherapy in patients with neutropenia expected to last more than 7 days. Sixty-nine patients with neutropenia (<0.5 x 10(9)/1) were randomized during 94 episodes of fever to receive either cefepime monotherapy (n=76) or combination therapy with trimethoprim/sulfamethoxazole plus amikacin (TMP/SMZ plus AMI, n=18). A successful response to cefepime was seen in 31/76 (41%) episodes, with 10/36 (28%) in microbiologically documented infections, 3/4 (75%) in clinically documented infections and 18/36 (50%) in fever of unknown origin. No patient in either treatment group died due to the presenting infection. One patient in the cefepime group discontinued treatment due to a rash. Susceptibility testing of blood isolates by E-test strip showed low MIC values to cefepime for most isolates. It is concluded that cefepime monotherapy appeared both safe and effective as empirical therapy in patients with febrile neutropenia.
