Study of Vitamin D and Effect on Heart Disease and Insulin Resistance
The Effect of Vitamin D Supplementation on Endothelial Function, Inflammation and Insulin Resistance in HIV
The purpose of this study is to evaluate how Vitamin D affects endothelial function, inflammation, lipids, insulin resistance, vitamin D levels, and PTH.
Randomized placebo controlled trial of vitamin D supplementation in HIV infected subjects with vitamin D deficiency
