All patients were > 18 years old without prior cryptococcal meningitis, without clinical suspicion of cryptococcal meningitis, regardless of antiretroviral (ART) status, and with CD4 counts < 200 cells/mu l. Serum CRAG was tested by LFA in all patients, and whole blood CRAG was tested by LFA in positive cases. results We enrolled 163 participants of whom 61% were men. The duration of HIV diagnosis was a median of 8 (range, 1-29) years. 26% were antiretroviral (ART)-naive, and 74% were ARTexperienced. The median CD4 cell count was 25 (range, 1-192) cells/mu l. Five patients (3.1%; 95% CI, 1.0-7.0%) were asymptomatic CRAG-positive. Positive results cases were cross-verified by performing LFA in whole blood. conclusions 3.1% of HIV-infected inpatients with CD4 < 200 cells/ll without symptomatic meningitis had cryptococcal antigenemia in Sao Paulo, suggesting that routine CRAG screening may be beneficial in similar settings in South America. Our study reveals another targeted population for CRAG screening: hospitalised HIV-infected patients with CD4 < 200 cells/mu l, regardless of ART status. Whole blood CRAG LFA screening seems to be a simple strategy to prevention of symptomatic meningitis.engrestrictedAccessCryptococcuscryptococcal meningitiscryptococcal screeningHIV/AIDScryptococcal polysaccharideprevalencemeningitiscohortburdenarticleCopyright WILEY-BLACKWELL10.1111/tmi.12790Public, Environmental & Occupational HealthTropical Medicine1365-3156
