Hepatosplenic candidiasis: successful treatment with fluconazole.

PURPOSE To determine if fluconazole is effective treatment for hepatosplenic candidiasis that has not resolved with amphotericin B and flucytosine treatment. PATIENTS AND METHODS Six patients (ages 3 to 44) with acute leukemia and hepatosplenic candidiasis who did not respond to prior antifungal therapy were treated with fluconazole. RESULTS All six patients had fever and three had nausea and vomiting; computed tomographic (CT) scan showed lucencies in the liver in six, lucencies in the spleen in five, and lucencies in the kidneys in three. Prior therapy with 1.6 to 4 g of amphotericin B in the five adults and 526 mg of amphotericin B in the child (with the addition of flucytosine in four) failed to improve clinical symptoms or lucencies in the liver, spleen, and kidneys seen on CT scan. Fluconazole was given at a dose of 200 to 400 mg daily (70 to 100 mg in the child) for 2 to 14 months. All patients had resolution of fever and other symptoms in 2 to 8 weeks. Improvement of the lesions noted on CT scan was seen in 4 to 8 weeks in all patients. Total resolution of lesions noted on CT scan occurred by 4 weeks in two patients, but took 4 to 5 months for three patients and 13 months for one patient. Three patients had relapse of their acute leukemia and two died, presumably cured of their candidiasis. Two patients underwent successful bone marrow transplantation without relapse of their candidiasis. CONCLUSION Fluconazole appears to be useful in the treatment of hepatosplenic candidiasis that has not resolved with amphotericin B and flucytosine therapy.
