Azole therapy for trichosporonosis: clinical evaluation of eight patients, experimental therapy for murine infection, and review.
We studied the in vivo antifungal activity of azoles in humans and in a murine model of disseminated trichosporonosis. Eight patients infected with Trichosporon species were treated with fluconazole, SCH 39304, or miconazole for 2-26 weeks. Four patients had fungemia, two patients had disseminated trichosporonosis, and one patient each had soft-tissue infection and cystitis. Response of trichosporonosis to azoles was seen in all eight patients, although one patient died with disseminated aspergillosis while still receiving SCH 39304. A literature review indicated that responses to ketoconazole or miconazole were noted in four patients with trichosporonosis. In the experimental infection, amphotericin B, SCH 39304, and fluconazole were effective in prolonging survival and reducing fungal counts in the kidneys of mice infected with a clinical strain of Trichosporon beigelii. Fluconazole but not amphotericin B prolonged survival of mice infected with a clinical strain of Trichosporon capitatum. We conclude that azoles represent effective therapy for infection with Trichosporon species.
