Azole resistance in Candida albicans
Summary
A Candida albicans isolate showed cross-resistance to multiple azole antifungals, failing to respond to treatment in both in-vitro and animal models for vaginal and disseminated infections.
Area of Science:
- Medical Mycology
- Antifungal Drug Resistance
Background:
- Chronic mucocutaneous candidosis (CMC) can be challenging to treat.
- Azole antifungals are commonly used for Candida infections.
Observation:
- A Candida albicans isolate from a relapsed CMC patient exhibited resistance.
- This isolate was tested alongside sensitive and resistant strains.
- In-vitro and animal models were used for evaluation.
Findings:
- The patient isolate displayed cross-resistance to all tested imidazole and triazole antifungals.
- Treatment with miconazole, ketoconazole, itraconazole, and fluconazole was ineffective in animal models.
- This suggests a broad resistance mechanism in the Candida albicans isolate.
Implications:
- This highlights the clinical challenge posed by azole-resistant Candida albicans.
- Understanding resistance mechanisms is crucial for developing new antifungal therapies.
- Alternative treatment strategies may be necessary for patients with resistant infections.
