The epidemiological profile of the HIV virus has undergone substantial modifications with advances in antiretroviral therapy. There has been a sharp decline in morbi-mortality levels of HIV-infected patients, which has resulted in higher survival rates. The HIV seropositive population is living longer and more exposed to chronic complications caused by the disease itself and the prolonged use of antiretrovirals. Initially, metabolic alterations were reported, increasing cardiovascular disease risk. Subsequently, damage on bone metabolism was related. Vitamin D insufficiency has now reached epidemic proportions, even in healthy individuals living in the tropics. Recent data suggest the hypovitaminosis D association with metabolic syndrome, immune diseases, diabetes and hypertension. Little is known regarding the effects of HIV/Aids and its treatment on the metabolism of vitamin D. In HIV-positive patients, factors linked to the virus itself and the use of antiretrovirals may be added to the other causes of hypovitaminosis D.
