Successful treatment with liposomal amphotericin B in two patients with persisting fungemia

Abstract
Two granulocytopenic patients in whom fungemia persisted despite therapy with deoxycholate amphotericin B were subsequently successfully treated by daily intravenous administration of amphotericin B entrapped in sonicated liposomes made of egg yolk lecithin, cholesterol and stearylamine in a molar ratio of 4:3:1. High serum concentrations of amphotericin B could be maintained in both patients during therapy with liposomal amphotericin B and were associated with high in vitro antifungal activity. Liposomal amphotericin B was tolerated much better than the deoxycholate preparation. These findings suggest that the liposomal amphotericin B preparation is superior in the treatment of fungemia in granulocytopenic patients, and that randomized trials are warranted.
