HISTOPLASMOSIS IN THE ACQUIRED-IMMUNODEFICIENCY-SYNDROME (AIDS) - TREATMENT WITH ITRACONAZOLE AND FLUCONAZOLE

The manifestations of histoplasmosis in 20 patients with the acquired immunodeficiency syndrome are presented. In this series, patients were treated with either itraconazole or fluconazole. Twelve patients received treatment with itraconazole at 400 mg/day, including two patients who had not responded to treatment with fluconazole at 100 mg/day. Of the responses, seven were classified as remissions (mean treatment duration of 24 months), two as improvements, and three as failures. Ten patients received fluconazole. Of the responses, three were classified as remissions (mean treatment duration of 12 months), one as improvement, and six as failures. Of the 10 patients treated with fluconazole, five received doses of 100 mg/day, and five were given doses of 400 or 800 mg/day. The differences in outcome among the five patients receiving the lower dose of fluconazole (one remission, one improvement, and three failures) and the five patients given the higher doses of fluconazole (two remissions and three failures) were negligible. One other patient showed signs of histoplasmosis while receiving fluconazole at 50 mg/day for treatment of thrush. Three failures (two treated with itraconazole and one with fluconazole) followed lapses in azole therapy because of associated conditions. Azole therapy was well tolerated. The treatment responses in this pilot series appear promising in comparison with those reported in the literature with amphotericin B or ketoconazole.
