Liposomal amphotericin B prevents invasive fungal infections in liver transplant recipients. A randomized, placebo-controlled study

Abstract

Eighty-six consecutive liver transplant recipients were prospectively randomized in a double-blind, placebo-controlled antifungal prophylaxis study. Seventy-seven patients received 5 days of prophylaxis starting during the transplantation with either liposomal amphotericin B (AmBisome) 1 mg/kg/day or placebo. Among 40 AmBisome-treated patients, no invasive Candida infection was seen during the first month, compared with 5 invasive Candida albicans infections among 37 control patients (P < 0.05). Furthermore, 1 placebo patient experienced Aspergillus niger pneumonia. Thus, the overall incidence of invasive fungal infections was 0/40 (0%) in the AmBisome group versus 6/37 (16%) in the placebo group (P < 0.01). Patient survival at 30 days was 92% versus 94% for AmBisome- and placebo-treated patients, respectively. One patient experienced backache related to AmBisome infusion. Two patients had transient thrombocytopenia possibly caused by AmBisome treatment. AmBisome was otherwise well tolerated. The total cost for all antifungal drugs used in both groups was equal. However, prophylaxis with AmBisome was $5000 less expensive than treatment of proven invasive fungal infections among placebo patients.
