Diagnosis and Management of Cryptococcal Relapse

Area of Science:

• Infectious Diseases
• Immunology
• Public Health

Background:

• Cryptococcal meningitis mortality remains high in sub-Saharan Africa despite advances in antifungal therapy and antiretroviral therapy (ART).
• Relapse of cryptococcal meningitis is a significant contributor to mortality and presents a diagnostic challenge, often confused with immune reconstitution inflammatory syndrome (IRIS).

Purpose of the Study:

• To review diagnostic and management strategies for cryptococcal meningitis relapse.
• To highlight challenges in resistance testing and managing refractory cases.
• To identify factors influencing relapse risk.

Main Methods:

• Clinical case scenario presentation.
• Review of case definitions and differential diagnoses for relapse.
• Emphasis on current diagnostic and management strategies.
• Discussion of challenges in resistance testing and refractory case management.

Main Results:

• Relapse risk is influenced by induction therapy choice (fluconazole monotherapy increases risk and selects for resistance).
• Non-adherence to or lack of secondary prophylaxis is a key risk factor.
• Poor linkage-to-care or retention-in-care within HIV ART programs contributes to relapse.

Conclusions:

• Effective management of cryptococcal meningitis relapse requires careful consideration of induction therapy, secondary prophylaxis, and robust HIV care programs.
• Addressing challenges in resistance testing and managing refractory cases is crucial for improving outcomes.
