Cryptococcal antigenemia in people living with HIV and AIDS.

To assess the prevalence of cryptococcal antigenemia among people living with HIV/AIDS (PLHA) with CD4 ≤100/mm3. This observational study was performed on PLHA with laboratory-confirmed CD4 ≤100/mm3. All PLHA were recruited irrespective of their duration of HIV diagnosis, antiretroviral therapy (ART) naïve, or ART failure. The prevalence of cryptococcal antigen (CrAg) was assessed in 102 PLHA, with CD4 ≤100/mm3, using a latex agglutination test on serum samples. All the subjects were followed up for 3 months. Amongst 102 PLHA, 62 (60.8%) and 40 (39.2%) patients were ART-naïve and ART failures, respectively, with 2.9% (n = 3) having clinical features of meningitis and 6.8% (n = 7) patients being asymptomatic CrAg-positive. At the 3 month follow-up, total mortality was 10.8%, of which 33.3% and 8.8% were among CrAg-positive and negative patients (p = 0.05). Mortality in asymptomatic and meningitis symptomatic CrAg-positive patients was 1.03% (n = 1) and 2.06% (n = 2), respectively. Of note, five patients were lost to follow-up. Cryptococcal antigenemia is common among patients with CD4 ≤100/mm3 who were either ART naïve or had treatment failure. Asymptomatic patients who underwent pre-emptive therapy demonstrated good clinical outcomes.
