CohortAs part of screening for enrollment into the Adjunctive Sertraline for Treatment of HIV-Associated Cryptococcal Meningitis (ASTRO-CM) clinical trial, we prospectively consented 1201 HIV-infected adults who presented with suspected meningitis to evaluate for the etiology of meningitis at Mulago National Referral Hospital and Mbarara Regional Referral Hospital in Uganda. Study participants were HIV- infected adults (aged ≥18 years) with signs/symptoms of meningitis who provided written informed consent for lumbar puncture, diagnostic testing, and collection of research data.

Disease Introduction MechanismCryptococcal meningitis is the most common cause of meningitis in sub-Saharan Africa and accounts for 15% of human immunodeficiency virus (HIV)/AIDS-related deaths glob- ally. Cryptococcal antigenemia, which precedes the development of cryptococcal meningitis, has a prevalence of 8.8% among HIV-infected Ugandan adult outpatients with CD4 T-cell counts <100 cells/μL, and this prevalence is 2-fold greater among those hospitalized. Globally, the cryptococcal antigenemia prevalence is estimated at 6% in HIV-infected individuals with CD4 T-cell counts <100 cells/ μL.
