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.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
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.

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
Antifungal Agents01:15

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
