[Initiation of antiretroviral therapy in HIV-infected patients with severe immunodeficiency in Belo Horizonte, Minas Gerais State, Brazil].

The main objective was to assess the proportion of delayed initiation of antiretroviral therapy (ART) and associated factors. This was a cross-sectional study of 310 patients enrolled in two public health centers in Belo Horizonte, Minas Gerais State, Brazil. Delayed ART initiation was defined as starting treatment with a CD4 count lower than 200 cells/mm(3) or clinical symptoms of severe immunodepression at the time of first antiretroviral prescription. The majority of participants were males (63.9%), had no health insurance (76.1%), and started ART less than 120 days after the first medical visit (75.2%). The proportion of delayed ART initiation was 68.4%. Unemployment, referral by a health professional for HIV testing, fewer than two medical visits in the six months prior to ART initiation, and time between first medical visit and ART initiation less than 120 days were independently associated with the outcome. Our results suggest that every patient 13 to 64 years of age should be offered HIV testing, which could increase the rate of early HIV diagnosis, and thus patients that tested positive could benefit from timely follow-up and antiretroviral therapy.
