Abstract:
Cryptococcosis as a complication of the immunocompromised host has dramatically increased in frequency since the start of the AIDS epidemic. This trend has heightened awareness of the complications of cryptococcal meningitis; of these, intracranial hypertension is common, severe, and life-threatening, as exemplified by three cases in our institutions presented here in detail. An aggressive approach to management of this complication has not been the standard of care, but neurosurgical interventional studies combined with physiologic observations suggest early intervention may reduce the devastating morbidity and mortality.
Insights
Cryptococcosis complications, especially cryptococcal meningitis, are rising in immunocompromised patients. Early aggressive management of intracranial hypertension may improve outcomes and reduce mortality.
Area of Science:
- Infectious Diseases
- Neuroscience
- Immunology
Background:
- Cryptococcosis incidence has surged in immunocompromised individuals, particularly since the AIDS epidemic.
- Cryptococcal meningitis is a significant complication, frequently leading to severe intracranial hypertension.
Observation:
- Three detailed case studies illustrate the severity and life-threatening nature of intracranial hypertension in cryptococcal meningitis.
- Current management strategies for this complication have not consistently involved aggressive intervention.
Findings:
- Intracranial hypertension is a common, severe, and life-threatening complication of cryptococcal meningitis in immunocompromised hosts.
- Physiologic observations and neurosurgical interventional studies suggest potential benefits of early intervention.
Implications:
- An aggressive management approach for intracranial hypertension in cryptococcal meningitis warrants further investigation.
- Early intervention may significantly reduce the severe morbidity and mortality associated with this condition.
