RESUMO
AIM: To compare the efficacy of imipenem/cilastatine and ceftazidime-amikacin in the treatment of febrile neutropenic patients. DESIGN: Open, prospective and randomized clinical study. PATIENTS: Fifty two patients (26 female) aged 16 to 80 years old with 60 episodes of neutropenia were studied. They were randomly assigned to receive imipenem/cilastatine in doses of 500 mg iv qid or the combination of ceftazidime 1 to 1.5 g iv tid and amikacin 7.5 mg/kg iv bid. RESULTS: Global response to initial therapy was 53% in patients receiving imipenem/cilastatine and 37% in those receiving ceftazidime-amikacin (p = ns). When other antimicrobial were added, a 90 and 85% infection eradication success was achieved respectively. Six febrile episodes in the group receiving imipenem/cilastatine and 12 episodes in the group receiving ceftazidime-amikacin had Gram positive cocci as the sole infectious agent (p < 0.04). A lower duration of neutropenia had a favorable influence on treatment outcome. Three patients receiving imipenem/cilastatine (10%) and four receiving ceftazidime-amikacin (13%) died. Superinfections and toxicity related to antibiotics were minimal in both groups. CONCLUSIONS: Imipenem/cilastatine and the combination of ceftazidime with amikacin were equally effective in the treatment of febrile episodes in neutropenic patients.
