Summary
Fluconazole-resistant mucosal candidosis is a growing issue in HIV patients. Intravenous amphotericin B is effective for severe cases, highlighting potential azole cross-resistance in recurrent infections.
Area of Science:
- Mycology
- Infectious Diseases
- HIV Medicine
Background:
- Mucosal candidosis is a common opportunistic infection in individuals with advanced HIV.
- Fluconazole is a primary antifungal agent for treating candidosis.
- Emerging antifungal resistance poses a significant challenge in managing HIV-related infections.
Purpose of the Study:
- To document fluconazole-resistant HIV-related mucosal candidosis.
- To correlate in vitro antifungal susceptibility with clinical outcomes.
- To evaluate alternative treatment strategies for refractory cases.
Main Methods:
- Retrospective chart review of patients with fluconazole failure and those with low CD4 counts.
- Prospective in vitro susceptibility testing of Candida isolates.
- Analysis of clinical data including CD4 counts and antifungal dosing.
Main Results:
- Nine cases (5.8%) of fluconazole failure were identified, with reduced in vitro susceptibility in all isolates.
- Intravenous amphotericin B demonstrated efficacy in severe cases, suggesting azole cross-resistance.
- Higher cumulative fluconazole doses were associated with treatment failure.
Conclusions:
- Clinical fluconazole failure is a significant problem in HIV-positive individuals with recurrent mucosal candidosis.
- Antifungal resistance necessitates alternative treatment approaches.
- Monitoring antifungal susceptibility is crucial for effective management.

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...
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,...
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...
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...
