Summary

Azole antifungal agents are most effective for preventing fungal infections in immunocompromised patients. These drugs offer better tolerance than nystatin, guiding prophylaxis choices for various patient groups.

Area of Science:

  • Medical Mycology
  • Infectious Diseases
  • Pharmacology

Background:

  • Fungal infections pose a significant threat to immunocompromised individuals, including those in hematology-oncology, surgical, solid organ transplant, and HIV infection populations.
  • Effective antifungal prophylaxis is crucial for reducing morbidity and mortality in these vulnerable groups.

Purpose of the Study:

  • To conduct a literature review on the efficacy and safety of antifungal agents for prophylaxis in immunocompromised hosts.
  • To develop evidence-based guidelines for antifungal prophylaxis regimens in specific immunocompromised patient populations.

Main Methods:

  • Comprehensive review of English-language clinical trials, with a focus on controlled studies.
  • Discussion of key trials evaluating antifungal prophylaxis efficacy and safety in immunocompromised patients.

Main Results:

  • Azole compounds (clotrimazole, ketoconazole, fluconazole) demonstrate superior efficacy and tolerability compared to nystatin for antifungal prophylaxis.
  • Antifungal prophylaxis is not routinely recommended for surgical patients, but is indicated for oropharyngeal candidiasis in advanced HIV and for cryptococcal meningitis relapse prevention.
  • Adverse effects are generally mild and similar across agents, though nystatin may have higher rates of nausea and vomiting.

Conclusions:

  • Azole agents are the most effective and best-tolerated options for antifungal prophylaxis in immunocompromised hosts.
  • Cost may influence the choice between different azole agents.
  • Future research should compare new antifungal treatments and explore the link between local colonization and systemic infection.
