Inadequacy of High-Dose Fluconazole Monotherapy among Cerebrospinal Fluid Cryptococcal Antigen (CrAg)-Positive Human Immunodeficiency Virus-Infected Persons in an Ethiopian CrAg Screening Program

A total of 817 human immunodeficiency virus-infected Ethiopians with CD4 <150 cells/mL underwent plasma cryptococcal antigen (CRAG) screening. CRAG prevalence was 6.2%. Of participants with plasma CRAG titers >1:640, 96% (27 of 28) had cryptococcal meningitis (cerebrospinal fluid CRAGpositive) whereas 50% (7 of 14) with 1:160-1:320 titers had meningitis. With fluconazole 1200 mg/d therapy, 68% of meningitis patients (23 of 34) died within 3 months. Plasma CRAG titers >1:160 predict meningitis, requiring more intensive antifungal therapy.
