Cryptococcal infection of the central nervous system
Clinical and Experimental Neurology
|January 1, 1985
Summary
Central nervous system cryptococcal infections present variably. Combination therapy with amphotericin B and 5-fluorocytosine is effective but requires careful monitoring for toxicity.
Area of Science:
- Infectious Diseases
- Mycology
- Neurology
Background:
- Cryptococcal infections of the central nervous system (CNS) pose diagnostic and therapeutic challenges.
- The presentation of CNS cryptococcosis can be highly variable, complicating early recognition.
- Standard treatment often involves combination antifungal therapy.
Observation:
- Two cases of CNS cryptococcosis are presented, highlighting diverse clinical presentations.
- Initial combination therapy with amphotericin B and 5-fluorocytosine yielded clinical and serological responses.
- Both patients experienced dose-limiting toxicities, necessitating discontinuation of 5-fluorocytosine.
Findings:
- Combination therapy demonstrated superiority over amphotericin B monotherapy.
- Readministration of 5-fluorocytosine at lower doses in one case led to favorable outcomes.
- Close monitoring of renal function, blood counts, and serum drug levels is crucial for managing toxicity.
Implications:
- Optimizing combination antifungal regimens for CNS cryptococcosis is essential.
- Careful patient monitoring is key to mitigating severe adverse events associated with treatment.
- Effective management requires a minimum of six weeks of therapy with thorough clinical, mycological, and serological assessment.
