Cryptococcal meningitis in acquired immunodeficiency syndrome
Objective:
To study the clinical course and outcome of cryptococcal meningitis (CM) in patients with acquired immunodeficiency syndrome (AIDS).
Method:
Patients infected with human immunodeficiency virus (HIV) and symptoms suggestive of meningitis were evaluated with detailed history, clinical examination and investigations. Diagnosis of CM was based on positive India ink preparation or positive fungal culture of CSF. All patients were treated with amphotericin those showing response were put on oral fluconazole.
Result:
A total of 431 patients with HIV infection were admitted to this centre during the study period, of these 15 were diagnosed to have CM. Majority of the patients had a subacute presentation with signs of meningeal irritation seen in only seven patients. India ink preparation and positive fungal culture on cerebrospinal fluid (CSF) established diagnosis in all cases. All patients were treated with amphotericin B and fluconazole. Complete response was noticed in seven patients, two patients were lost to follow-up and six patients died during the course of therapy. Raised intracranial tension (ICT) and disseminated disease were associated with poor prognosis.
Conclusion:
CM is a common opportunistic fungal infection in patients with AIDS. A high index of clinical suspicion and routine mycological surveillance is required to diagnose this infection. Majority of patients respond to therapy except those who have disseminated infection, altered sensorium and features of raised ICT at presentation.
Insights
Cryptococcal meningitis (CM) is a frequent opportunistic infection in individuals with acquired immunodeficiency syndrome (AIDS). Early diagnosis and treatment are crucial, as disseminated disease and raised intracranial pressure indicate a poor prognosis.
Area of Science:
- Infectious Diseases
- Neurology
- Immunology
Background:
- Cryptococcal meningitis (CM) is a significant opportunistic infection in patients with acquired immunodeficiency syndrome (AIDS).
- Understanding the clinical presentation and outcomes of CM in this population is vital for effective management.
Purpose of the Study:
- To investigate the clinical course and patient outcomes for cryptococcal meningitis (CM) in individuals with acquired immunodeficiency syndrome (AIDS).
Main Methods:
- Retrospective analysis of 431 human immunodeficiency virus (HIV)-infected patients admitted during the study period.
- Diagnosis of CM confirmed by positive India ink preparation or fungal culture of cerebrospinal fluid (CSF).
- Treatment involved amphotericin B followed by oral fluconazole for responding patients.
Main Results:
- Fifteen out of 431 HIV-infected patients were diagnosed with CM, predominantly with subacute presentations.
- Diagnosis was consistently established via CSF analysis (India ink or fungal culture).
- Seven patients showed complete response, two were lost to follow-up, and six died; raised intracranial tension and disseminated disease correlated with poor prognosis.
Conclusions:
- Cryptococcal meningitis (CM) is a common opportunistic fungal infection in patients with AIDS, necessitating high clinical suspicion and mycological surveillance.
- While many patients respond to amphotericin B and fluconazole, those with disseminated infection, altered sensorium, or raised intracranial pressure at presentation face poorer outcomes.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
