Cerebral cryptococcosis in Malaysia

Area of Science:

• Neurology
• Infectious Diseases
• Tropical Medicine

Background:

• Cryptococcal infection of the brain is a serious concern in tropical regions.
• An apparent rise in incidence has been observed in Malaysia and Singapore over the past decade.
• Overt immunological deficiency is rarely evident in affected patients.

Purpose of the Study:

• To review the characteristics of cryptococcal brain infections in a tropical setting.
• To highlight challenges in management and treatment resistance.
• To underscore the need for further research and novel antifungal agents.

Main Methods:

• Review of clinical encounters with cryptococcal brain infections.
• Analysis of patient data regarding incidence, clinical presentation, and complications.
• Assessment of treatment outcomes and drug resistance patterns.

Main Results:

• Meningitic form of cryptococcal infection is not uncommon.
• Hydrocephalus affects approximately three-quarters of meningitis patients, often managed with shunts.
• Treatment with 5-fluorocytosine led to resistance in about 25% of patients.
• Intracerebral cysts were clinically suspected but difficult to treat effectively.

Conclusions:

• Cryptococcal meningitis requires careful management, especially regarding hydrocephalus.
• Antifungal resistance to 5-fluorocytosine is a significant clinical challenge.
• Further epidemiological studies and the development of new antifungal agents are crucial.
