    Prevalence and Associated Factors of Cryptococcal Antigenemia in HIV-Infected Patients with CD4 < 200 Cells/mu L in Sao Paulo, Brazil: A Bayesian Analysis

    Cryptococcosis is a severe life-threatening disease and a major cause of mortality in people with advanced AIDS and CD4 <= 100 cells/ mu L. Considering the knowledge gap regarding the benefits of routine application of antigenemia tests in HIV-infected patients with 100-200 CD4 cells/mu L for the prevention of cryptococcal meningitis (CM), we aimed to evaluate the prevalence of positive antigenemia through lateral flow assay (LFA) and associated factors in HIV-infected patients with CD4 < 200 cells/ mu L. Our findings of 3.49% of positive LFA (LFA+) patients with CD4 < 100 cells/mu L and 2.24% with CD4 between 100-200 cells/mu L have been included in a Bayesian analysis with 12 other studies containing similar samples worldwide. This analysis showed a proportion of 3.6% LFA+ patients (95% credible interval-Ci [2.5-5.7%]) with CD4 < 100 cells/mu L and 1.1% (95%Ci [0.5-4.3%]) with CD4 between 100-200 cells/mu L, without statistical difference between these groups. The difference between mortality rates in LFA+ and negative LFA groups was e = 0.05013. Cryptococcoma and CM were observed in the LFA+ group with 100-200 and <100 CD4 cells/mu L, respectively. Considering the benefits of antifungal therapy for LFA+ patients, our data reinforced the recommendation to apply LFA as a routine test in patients with 100-200 CD4 cells/ mu L aiming to expand cost-effectiveness studies in this group.
