Imipenem or cefoperazone-sulbactam combined with vancomycin for therapy of presumed or proven infection in neutropenic cancer patients.
The purpose of this prospective randomized study was to compare the efficacy and safety of imipenem and cefoperazone-sulbactam combined with vancomycin for the treatment of fever in neutropenic cancer patients. Patients were assigned to either imipenem 500 mg/m2 (500 mg for bone marrow transplant recipients) every 6 h or cefoperazone (2 g)-sulbactam (1 g) every 8 h All patients received vancomycin 1 g every 12 h. A total of 457 febrile or infectious episodes occurring in 407 patients were entered in the study. The response rate was 73% for imipenem plus vancomycin and 74% for cefoperazone-sulbactam plus vancomycin among the 369 episodes that could be evaluated. Response rates were comparable for the two regimens with regard to infecting organism, administration of antimicrobial prophylaxis, and neutrophil count and trend. The frequency of side-effects was significantly higher for imipenem plus vancomycin (11% vs.5%, p = 0.02), due to therapy-associated nausea and vomiting (5.3% vs. 0%, p = 0.0004). The overall frequency of superinfections was similar with both regimens, but Clostridium difficile colitis occurred significantly more often in patients receiving imipenem plus vancomycin (5 vs. 0, p = 0.02). In this study cefoperazone-sulbactam plus vancomycin was an effective alternative to imipenem plus vancomycin for initial therapy of fever in neutropenic patients.
