Résumé : The aim of this study was to describe the clinical and immunological profile of patients infected with HIV after initiation of antiretroviral therapy. Sociodemographic characteristics, clinical and immunological patients were recorded. Chi square test and Mann-Whitney were used to compare variables. The multivariate regression model identified risk factors. So that, 936 (56.2%) patients were in stages III and IV of the WHO and 65.2% at an advanced stage of the disease. Factors associated with initiation at an advanced stage, were male sex (p = 0.007) and time to diagnosis (p = 0.005). In 2/3 cases, treatment is started at an advanced stage of disease. It is therefore important to intensify awareness campaigns for early detection and encourage patients to ensure regular medical follow-up screening.
