Vitamin D Deficiency in HIV-Infected Women on Antiretroviral Therapy Living in the Tropics.

The effects of HIV/AIDS and antiretroviral drugs on vitamin D metabolism are still mostly unknown. This was a cross-sectional study to estimate the prevalence of vitamin D deficiency and identify its association with the clinical and metabolic parameters among 214 HIV-positive female patients on antiretroviral therapy (ART) in Brazil. The prevalence of vitamin D deficiency (< 30 ng/ml) was 40.65% (87/214). Hypercholesterolemia, high LDL-c, duration of use of current antiretroviral regimen, hypertriglyceridemia, body mass index, age, hypertension, time with AIDS ≥ 10 years and hyperglycemia were selected for multivariate analysis (p < 0.20). After this analysis, hypercholesterolemia and use of current antiretroviral regimen ≥ 3 years remained independently associated with vitamin D deficiency. There was an inverse statistically significant correlation between total cholesterol and serum 25(OH)D levels. High prevalence of vitamin D deficiency was found among HIV-positive women on ART and was independently associated with its prolonged use and with hypercholesterolemia.
