Fluconazole prophylaxis of recurrent oral candidiasis in HIV-positive patients.

In a randomized, open study, the efficacy of fluconazole as a prophylaxis of recurrent oral candidiasis in patients with advanced stages of HIV-infection (CD4 cell count less than 100/mm3) was studied. For this purpose, the frequency of episodes of oral candidiasis during two different prophylaxis regimens (50 mg/day vs. 100 mg/day) were compared to an untreated control group. Sixty-five HIV-positive patients were included in the study from May, 1989 to January, 1990. Of these, 58 were evaluated over an observation time of 137-215 days. Prophylaxis with fluconazole clearly reduced the occurrence of oral candidiasis. In 20 out of 21 patients in the untreated control group, a total of 60 relapses occurred. In the prophylaxis group receiving 50 mg/day (group 2), two out of 18 patients had four relapses. In the group receiving 100 mg/day (group 3), four out of 19 patients had nine relapses in total. Of 3575 observation days in the control group, treatment due to oral candidiasis was necessary on 393 days (28%). In group 2, on 57 of 3316 days (2%), fluconazole in a higher dosage was administered for treatment. In group 3, relapse treatment with fluconazole 200 mg/day, or treatment with ketoconazole, became necessary in 116 out of 3314 observation days (3%). In all relapses, Candida albicans cfu greater than 10(3)/ml were isolated in the oral wash-outs. As compared to the untreated control group, fluconazole prophylaxis in a daily dosage of 50 as well as 100 mg led to significantly less frequent relapses of oral candidiasis (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
