Background: Low bone mineral density (BMD) is a significant comorbidity in HIV. However, studies evaluating vitamin D supplementation on bone health in this population are limited. This study investigates changes in bone health parameters after 12 months of supplementation in HIV-infected youth with vitamin D insufficiency. Methods: This is a randomized, active-control, double-blind trial investigating changes in bone parameters with 3 different vitamin D3 doses [18,000 (standard/control dose), 60,000 (moderate dose), and 120,000 IU/monthly (high dose)] in HIV-infected youth 8–25 years old with baseline serum 25-hydroxyvitamin D (25(OH)D) concentrations <30 ng/mL. BMD and bone turnover markers were measured at baseline and 12 months. Results: One hundred two subjects enrolled. Over 12 months, serum 25(OH)D concentrations increased with all doses, but the high dose (ie, 120,000 IU/monthly) maintained serum 25(OH)D concentrations in an optimal range (≥30 or ≥20 ng/mL) throughout the study period for more subjects (85% and 93%, respectively) compared with either the moderate (54% and 88%, respectively) or standard dose (63% and 80%, respectively). All dosing groups showed some improvement in BMD; however, only the high-dose arm showed significant decreases in bone turnover markers for both procollagen type 1 aminoterminal propeptide (−3.7 ng/mL; P = 0.001) and Β-CrossLaps (−0.13 ng/mL; P = 0.0005). Conclusions: High-dose vitamin D supplementation (120,000 IU/mo) given over 12 months decreases bone turnover markers in HIV-infected youth with vitamin D insufficiency, which may represent an early, beneficial effect on bone health. High vitamin D doses are needed to maintain optimal serum 25(OH)D concentrations.
