Success of Standard Dose Vitamin D Supplementation in Treated Human Immunodeficiency Virus Infection.

ABSTRACT: Background.  Vitamin D insufficiency is prevalent in human immunodeficiency virus-positive (HIV+) persons. Human immunodeficiency virus and antiretroviral therapy (ART) may create unique risk factors, and the optimal vitamin D repletion and maintenance regimen in HIV+ persons remains unclear. Methods.  Human immunodeficiency virus-positive adults on suppressive ART underwent routine serum 25-hydroxyvitamin D (25OHD) screening. Persons with vitamin D insufficiency (25OHD <30 ng/mL) received open-label, oral vitamin D3 50 000 international units (IU) twice weekly for 5 weeks, then 2000 IU daily to complete 12 weeks. We predicted 70% (95% confidence interval, 60%-80%) repletion to 25OHD ≥30 ng/mL compared with 85% among historical HIV-negative controls. Eighty participants provided 91% power
