Sumario:Data presented previously as an abstract at the 2011 CUGH Global Health Conference in Montreal, Canada on 15 Nov 2011. The long-term survival of HIV-infected persons with symptomatic cryptococcal meningitis and asymptomatic, subclinical cryptococcal antigenemia (CRAG+) is unknown. We prospectively enrolled 25 asymptomatic, antiretroviral therapy (ART)-naïve CRAG+ Ugandans with CD4<100 cells/mcL who received pre-emptive fluconazole treatment (CRAG+ cohort) and 189 ART-naïve Ugandans with symptomatic cryptococcal meningitis treated with amphotericin (CM cohort). The 10-week survival was 84% (95%CI: 70–98%) in the CRAG+ cohort and 57% (95%CI: 50%–64%) in the CM cohort. The CRAG+ cohort had improved five-year survival of 76% (95%CI: 59%–93%) compared to 42% (95%CI: 35%–50%) in the CM cohort (P = 0.001). The two cohorts had similar immunosuppression pre-ART with median CD4 counts of 15 vs. 21 CD4/mcL in the CRAG+ and CM cohorts, respectively (P = 0.45). Despite substantial early mortality, subsequent 5-year survival of persons surviving 6-months was excellent (>88%), demonstrating that long term survival is possible in resource-limited settings. Pre-ART CRAG screening with preemptive fluconazole treatment and improved CM treatment(s) are needed to reduce AIDS-attributable mortality due to cryptococcosis which remains 20–25% in sub-Saharan Africa.
