Prevalence and Sequelae of Cryptococcal Antigenemia in Antiretroviral Therapy–Experienced Populations: An Evaluation of Reflex Cryptococcal Antigen Screening in Botswana

Abstract

CrAg-positivity rates in an ART-experienced population were comparable to those seen in ART-naive populations. Repeat screening identified individuals who seroconverted to CrAg positivity and were at risk of cryptococcal disease. CrAg titers ≥1:80 can help identify the individuals at highest risk of death for more intensive management.
