Abstract:
We compared the efficacy of a 400-mg once-weekly dosage versus a 200-mg daily dosage of fluconazole for the prevention of deep fungal infections in a multicenter, randomized, double-blind trial of 636 human immunodeficiency virus-infected patients to determine if a less intensive fluconazole regimen could prevent these serious but relatively infrequent complications of AIDS. In the intent-to-treat analysis, a deep fungal infection developed in 17 subjects (5.5%) randomly assigned to daily fluconazole treatment and in 24 (7.7%) given weekly fluconazole during 74 weeks of follow-up (risk difference, 2.2%; 95% confidence interval [CI], -1.7% to 6.1%). Thrush occurred twice as frequently in the weekly versus daily fluconazole recipients (hazard ratio, 0.59; 95% CI, 0.40-0.89), and in a subset of patients evaluated, fluconazole resistance was infrequent. Fluconazole administered once weekly is effective in reducing deep fungal infections in patients with AIDS, but this dosage is less effective than the 200-mg-daily dosage in preventing thrush.
Insights
A weekly fluconazole dose effectively prevents deep fungal infections in patients with human immunodeficiency virus (HIV). However, daily fluconazole is more effective at preventing thrush, a common fungal complication.
Area of Science:
- Infectious Diseases
- Mycology
- Public Health
Background:
- Deep fungal infections are serious complications in patients with acquired immunodeficiency syndrome (AIDS).
- Fluconazole is commonly used for fungal infection prophylaxis in immunocompromised individuals.
Purpose of the Study:
- To compare the efficacy of once-weekly versus daily fluconazole for preventing deep fungal infections in HIV-infected patients.
- To determine if a less intensive fluconazole regimen is effective in preventing fungal complications.
Main Methods:
- Multicenter, randomized, double-blind trial involving 636 HIV-infected patients.
- Comparison of 400-mg once-weekly fluconazole versus 200-mg daily fluconazole.
- 74 weeks of follow-up with intent-to-treat analysis.
Main Results:
- Deep fungal infections occurred in 5.5% of daily fluconazole recipients and 7.7% of weekly recipients (risk difference, 2.2%).
- Thrush occurred twice as frequently in weekly versus daily fluconazole recipients (hazard ratio, 0.59).
- Fluconazole resistance was infrequent in a subset of evaluated patients.
Conclusions:
- Once-weekly fluconazole is effective in reducing deep fungal infections in patients with AIDS.
- The 200-mg daily dosage of fluconazole is more effective than the weekly dosage in preventing thrush.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
