Failure of systemic empirical treatment with amphotericin B to prevent candidemia in neutropenic patients with cancer

Abstract

We undertook a retrospective review of all patients with hematologic malignancies in whom candidemia developed during chemotherapy-induced neutropenia in 1989 and 1990. Candidemia developed in 11 patients; five were receiving therapeutic doses of amphotericin B at the time of infection. Disseminated infection occurred in 2 of 5 patients with breakthrough infection and 3 of 6 patients with candidemia before receipt of amphotericin B. Among patients with breakthrough candidemia there was a trend toward more-prolonged neutropenia prior to infection (P = .069), but otherwise they were indistinguishable from other candidemic patients with regard to risk factors for candidemia. Amphotericin B-susceptible Candida albicans was isolated from two patients and Candida krusei from three patients with breakthrough infection. All patients were treated with amphotericin B; all breakthrough infections responded to treatment. Neutropenic patients with breakthrough candidemia were clinically similar to those whose candidemia preceded amphotericin B therapy, and there was no increase in morbidity and mortality among individuals with break-through infection. © 1996 by The University of Chicago.
