Empiric antibiotic and antifungal therapy for granulocytopenic patients with acute leukemia.
A prospective study was undertaken to determine the effectiveness of an empiric antibiotic treatment employing the combination of a beta-lactam and an aminoglycoside followed in non responders by vancomycin and amphotericin B after 48 and 96 hours respectively. We have evaluated 180 febrile episodes in 102 granulocytopenic leukemic patients. Febrile episodes (44%) were microbiologically documented; 29% were only clinically documented and 27% were possible. In the 180 evaluable episodes treated with a beta-lactam and an aminoglycoside the overall response rate was 61%. In non responders the addition of vancomycin increased the response rate to 83% and the subsequent addition of amphotericin B moved the total responders to 96%. Antibiotic related side effects were minimal. These data suggest the importance of an empiric strategy for treatment of bacterial infections arising in granulocytopenic patients. An early empiric antifungal therapy also appears necessary to control clinically undetected fungal invasion.
