Abstract

Insights

Cryptococcal meningitis (CM) in HIV patients presents variably, often leading to delayed diagnosis. Improving management of intracranial pressure and antifungal toxicity is crucial for better outcomes in these opportunistic infections.

Area of Science:

  • Infectious Diseases
  • Neurology
  • HIV Medicine

Background:

  • Opportunistic infections, such as Cryptococcal Meningitis (CM), are often the initial clinical manifestation of Human Immunodeficiency Virus (HIV) infection.
  • Understanding the clinical and laboratory features of HIV-associated CM is essential for timely diagnosis and management.

Purpose of the Study:

  • To describe the clinical and laboratory characteristics of HIV-associated CM.
  • To report in-hospital outcomes.
  • To analyze associations between these parameters and adverse outcomes.

Main Methods:

  • An observational study of a local cohort of HIV-associated CM patients in Santiago, Chile.
  • Descriptive analysis of 37 adult cases from 1995 to 2019 via chart review.
  • Inclusion criteria included confirmed CM and HIV diagnosis; relevant variables predicting adverse outcomes were explored.

Main Results:

  • 37 cases of HIV-associated CM were identified between 2000 and 2019, predominantly in men (86%) with a median age of 35.
  • CM was the first HIV manifestation in 32% of cases. Opening pressure was measured in only 10% of patients.
  • High rates of adverse events (94.4%) from antifungal therapy were observed. Mortality was 18.9%, associated with older age and longer headache duration.

Conclusions:

  • Clinical presentation and cerebrospinal fluid (CSF) findings in CM are highly variable, potentially delaying diagnosis.
  • Key areas for improvement include the inappropriate use of corticosteroids, managing antifungal toxicity, and optimizing treatment for elevated intracranial pressure.
