Fungal infections in AIDS. Cryptococcosis

Area of Science:

• Mycology
• Infectious Diseases
• Immunology

Background:

• Cryptococcus neoformans, Histoplasma capsulatum, and Coccidioides immitis are key fungal pathogens causing severe disseminated disease in AIDS patients.
• Cryptococcosis is the fourth most common opportunistic infection in AIDS, frequently presenting as meningitis or pneumonia.
• Unusual presentations include focal infections and unexplained fever in individuals with HIV.

Purpose of the Study:

• To highlight the importance of routine serum cryptococcal antigen screening in patients at risk for HIV.
• To outline the recommended diagnostic and treatment protocols for cryptococcosis in AIDS patients.
• To discuss the role of maintenance suppressive therapy and emerging oral azole regimens.

Main Methods:

• Routine serum cryptococcal antigen screening for at-risk patients.
• Diagnostic confirmation of cryptococcosis.
• Treatment initiation with amphotericin B.
• Monitoring for treatment response and implementation of maintenance therapy.

Main Results:

• Serum cryptococcal antigen testing is a critical screening tool.
• Amphotericin B is the mandatory initial treatment for established cryptococcosis.
• Maintenance suppressive therapy with amphotericin B is necessary after initial treatment.
• Oral azole antifungals show promise for long-term management.

Conclusions:

• Early detection and prompt treatment of cryptococcosis are essential for managing AIDS patients.
• Amphotericin B remains the cornerstone of initial therapy, followed by suppressive regimens.
• Further research into oral azole maintenance therapy is warranted for improved patient management.
