Daily fluconazole (FLU 200 mg) prophylaxis reduces the risk of deep
fungal disease in HIV infected patients with CD4 cells less than 200/mm
3 , but the low incidence of serious fungal infections requires an
estimated 11,756 doses of fluconazole to prevent each case (Powderly, et
al. NE.JM 1995;332:700). To evaluate the effectiveness of less intensive
antifungal prophylaxis, we conducted a double-blind, randomized study of
weekly (400 mg) versus daily (200 mg) FLU. 636 AIDS patients with CD4
cell counts less than 100/3 were treated for a mean of 332 days. In the
intent-to-treat analysis of the primary endpoint (deep fungal
disease),17 (5.4%) events occurred in the FLU daily arm and 24 (7.6%) in
the FLU weekly arm. [Risk ratio 1.49, 95% C.I. (0.79, 2.78)]. Dose
limiting toxicity and survival were similar. (Table: See Text).
Incidence of thrush was halved in the daily arm (28.4 episodes per 100
patient-1 years compared to the fluconazole weekly arm (63.7 episodes
per 100 patient-years). The hazard ratio for the time to first episode
of thrush was 0.49 [95% C.I. (0.37, 0.64)]. The 48 hour MIC90 for C.
albicans isolates obtained from patients with thrush was 16
micrograms/mL in the daily fluconzole arm and 8 micrograms/mL in the
weekly fluconazole arm. The distribution of MICs from available
breakthrough isolates (n=25) did not differ significantly between
groups. The prevalence of dermatophyte infections was significantly less
on the daily regimen [RR=O.61, 95% C.I. (0.4, 0.94). Weekly fluconazole
(400 mg) appears to provide similarly effective prophylaxis for deep
fungal infections as the standard regimen (200 mg daily) employing 3.5
times as much drug (1400 mg weekly), but is less effective in
suppressing thrush.
