Candida infection in massively burned patients.

Abstract

Immunosuppressed burned patients receiving antibiotics for suppression of bacterial infection are ideal hosts for opportunistic fungi. Massive excision of burns with autograft and homograft coverage has radically changed the course of disease. Three hundred ninety-three patients were admitted to the Shriners Burns Institute, of whom 125 patients had fungus cultured during their hospitalization and 42 patients subsequently developed involvement of three or more organs. Twenty-one of the 42 patients developed Candida septicemia requiring amphotericin B or flucytosine therapy. The mean third-degree burn in patients with Candida septicemia was 65% total body surface area compared to three-organ involvement/no clinical sepsis at 38% mean third-degree burn. Patients developing candidemia did so during the first week postburn and 7 days after excision therapy. It is hypothesized that massive burns with immunosuppression are further suppressed by repeated surgical intervention, anesthesia, and perioperative use of broad-spectrum antibiotics, further predisposing these patients to early development of Candida septicemia. With early recognition of burn wound invasion by routine biopsies, wound swabs, and early amphotericin therapy, the mortality has been reduced to 14% compared to 60-90% reported in other series.
