[Comparative study of cefpiramide + amikacin versus piperacillin + amikacin in granulocytopenic patients: a randomized, prospective study].

Cefpiramide + amikacin (CPM + AMK) was compared in a prospective randomized trial with our standard regimen of piperacillin plus amikacin (PIPC + AMK) as an empiric therapy for fever in 252 episodes of 141 patients with granulocytopenia. Initial profound granulocytopenia (fewer than 100/mm3 mature granulocytes) was present in approximately 69% of the patient trials in both treatment groups. Both groups were equally distributed in regard to age, disease, pretreatment WBC count and duration of antibiotic treatment, although septic shock was more frequently seen in CPM + AMK. Responses to PIPC + AMK and CPM + AMK were similar for microbiologically and clinically documented infection, while the response rate for clinically documented infections treated with PIPC + AMK was superior to CPM + AMK (63% vs. 52%). Patients with persistent granulocytopenia of less than 100/mm3 of mature granulocytes without a rise during therapy responded significantly less in both groups (22% vs. 9%) than those in whom the granulocyte count rose (79% vs. 79%). Toxicities of jaundice or disordered hepatic function test were infrequent in both groups. Disordered renal function test occurred in one case in PIPC + AMK groups.
