Purpose
Beta lactams are standard empirical therapy for febrile neutropenia (FN). The aim of this study was to evaluate the efficacy and safety of cefepime monotherapy compared with cefoperazone/sulbactam plus amikacin (CS + A) for empirical treatment of high risk FN.
Methods
One hundred seventy-five patients with 336 FN episodes were randomized to receive either cefepime (2 g q8h for adults and 50 mg/kg q8h for children) or CS (2 g q8h for adults and 50 mg/kg q8h for children) plus amikacin (15 mg/kg once a day). Positive response was defined as afebrile within 72 h of starting antibiotics, persistent afebrile status more than 48 h and no requirement of second-line antibiotics and antifungal agents.
Results
Three hundred thirty-six episodes were assessable for efficacy (168 cefepime, 168 CS + A). The positive response to antibiotics was identical for cefepime (53%) and CS + A (53%). Positive response was similar in MDI (microbiologically documented infection), 50 vs. 35% (p = 0.248), CDI (clinically documented infection), 50 vs. 35% (p = 0.259), combination CDI + MDI, 25 vs. 15% (p = 0.400), FUO (fever of unknown origin), 68 vs. 72% (p = 0.577) respectively in the two groups. The successful discontinuation of antibiotics at 72 h in FUO was similar in both groups (60 vs. 59%, p = 0.544). Total drug-related adverse events were similar in both groups (8 vs. 6%) except renal dysfunction was high in CS + A (1 vs. 7 events). Mortality was the same between two groups (8 vs 7%).
Conclusions
Cefepime monotherapy and CS + A had similar efficacy as first-line therapy for FN. Discontinuation of empirical antibiotics is safe and feasible approach in selected group of FUO patients.
