Optimal vitamin D (vit D) concentration and metabolism are essential for normal immune function, growth, muscle, bone, and inflammatory status in children, adolescents and adults with HIV/AIDS. The impact of vit D supplementation will be evaluated for safety and efficacy using clinically important outcomes, and this will overcome the critical barrier for use of vit D supplementation in research and clinical care. Inexpensive and easy to administer, vit D supplementation may prove to be an effective and feasible treatment for symptoms and prevention of side effects for people of all ages living with HIV/AIDS in the US and around the world.~The study is a 12-month randomized, double blind, placebo-controlled study of vitamin D3 (vit D) supplementation using 7000IU/day based on evidence from the Vit D Dose Finding Study-IRB 09-007332 in 58 subjects with both Perinatally Acquired (PA) and Behaviorally Acquired (BA) HIV/AIDS to assess the long-term safety in terms of serum calcium and 25OHD concentrations, and efficacy in terms of the effect of vit D supplementation on 25OHD, cathelicidin, growth (pre- and peripubertal participants), body composition, bone, muscle, immune and inflammatory status and HIV/AIDS disease severity and progression.~Primary Hypotheses:~H1: Vit D supplementation is safe and does not result in an increased incidence of elevated serum calcium (above age-specific range) associated with elevated serum 25OHD (>160 ng/mL) in treated subjects compared with the subjects receiving placebo.~H2: Vit D supplementation is significantly associated with both increased 25D and cathelicidin in treated subjects compared with subjects receiving placebo.
The purpose of this study is to evaluate safety and efficacy of vitamin D supplementation in children, adolescents and young adults with Human Immunodeficiency Virus and acquired immunodeficiency syndrome (HIV/AIDS). The study is a 12-month randomized, double blind, placebo-controlled study of vitamin D3 (vit D) supplementation using 7000IU/day based on evidence from the Vit D Dose Finding Study-IRB 09-007332.
