Combination therapy of disseminated Fusarium oxysporum infection with terbinafine and amphotericin B

A case of disseminated infection with Fusarium oxysporum following chemotherapy of acute myelogenous leukemia is reported. Antifungal treatment was successful with a 13-day course of oral terbinafine 250 mg t.i.d. in combination with amphotericin B deoxycholate 1.0–1.5 mg/kg qd and subsequently intravenous liposomal amphotericin B 5 mg/kg qd. Preceding monotherapy with amphotericin B deoxycholate 1.0–1.5 mg/kg qd had not stopped the progression of infection. The combination therapy described here represents a novel approach to the treatment of Fusarium spp. in the immunocompromised host in whom Fusarium spp. are known to cause disseminated infection with high mortality.
