Brief Summary:
The major goal of this study will be to conduct a randomized, double-blind, placebo-controlled, clinical trial of intermittent high-dose vitamin D3 supplementation (180,000IU) given at the point of care (every 3 months) after initiation of ART with tenofovir/ lamivudine/ efavirenz to compare its ability to mitigate reductions in bone mineral density over 12 months compared to placebo.

Condition or disease Intervention/treatment Phase
HIV/AIDS Osteoporosis Bone Loss Dietary Supplement: Vitamin D3 Other: Placebo Not Applicable

Detailed Description:

Studies among adult and pediatric populations have suggested vitamin D supplementation may be efficacious for mitigating the bone loss seen with tenofovir-based antiretroviral therapy (ART). Because patients with HIV face significant pill burden, competing priorities and health care associated costs, we seek to explore a pragmatic approach to prevention. The investigators propose a randomized controlled, double-blind, placebo intervention trial to assess the efficacy, tolerability, and safety of an intermittent high-dose vitamin D3 supplementation regimen given quarterly at the point of care for adult patients receiving free ART through the China National Free AIDS Treatment Program. The period of supplementation will be limited to the first 48 weeks after treatment initiation when ART-associated bone loss is most pronounced. This will be followed by supplementation of all participants with vitamin D3 from 48 to 96 weeks to compare the impact of early vitamin D3 supplementation (at ART initiation) versus late vitamin D3 supplementation (at 48 weeks) on change in BMD.

Furthermore, despite the rapid rise in access to ART in China, infrastructure to diagnose and manage osteoporosis is not always easily accessible for patients with HIV in China due to limited availability of dual-energy x-ray absorptiometry (DXA), the gold standard for BMD measurement. Therefore, the current proposal also seeks to bridge this gap by exploring the potential applications of quantitative ultrasound (QUS), a portable and low-cost method of assessing BMD that has been demonstrated to reliably predict fracture, in HIV care settings.

A total of 400 treatment-naïve Chinese adults diagnosed with HIV from 3 study sites in Beijing will be enrolled and followed with serial DXA exams to evaluate the primary aim. These 400 patients plus another 200 participants from 3 additional study sites from Fuzhou, Shenzhen, and Guangxi province, will be evaluated with serial QUS ultrasound examinations for the secondary aims. Serum and urine samples will be collected and stored at pre-specified time points.

Arm Intervention/treatment
Experimental: Vitamin D3 Supplementation Arm
This arm will receive 180,000IU vitamin D3 every 3 months from baseline through week 96.
Dietary Supplement: Vitamin D3
180,000IU Vitamin D3 oral emulsion

Placebo Comparator: Placebo Arm
This arm will receive placebo every 3 months from baseline through week 48, followed by 180,000IU vitamin D3 every 3 months from week 48 through week 96.
Other: Placebo

Primary Outcome Measures :
  1. Change in Bone Mineral Density (BMD) [ Time Frame: Baseline to week 48 ]
    In the three sites in Beijing (N=400), compare percent change in BMD at the lumbar spine and total hip, as measured by dual-energy x-ray absorptiometry (DXA) at week 48.

Secondary Outcome Measures :
  1. Immediate vs. Delayed Vitamin D3 Supplementation [ Time Frame: Weeks 48 to 96 ]
    In the three sites in Beijing (N=400), from 48 to 96 weeks, switch the placebo arm to vitamin D3 supplementation to compare percent change in BMD at 96 weeks between patients who initiated vitamin D3 supplementation at the start of ART versus those who initiated vitamin D3 after 1 year of ART.

  2. Change in Quantitative Ultrasound (QUS) Measures [ Time Frame: Baseline to 96 weeks ]
    In all six study sites (N=600), evaluate percent change in SOS and BUA over 48 weeks in the vitamin D treatment group compared with placebo, as measured by QUS. Further, evaluate the ability of QUS to independently identify the same group of patients at greatest risk for severe bone loss, as compared with risk stratification using DXA.

  3. Change in Biochemical Markers [ Time Frame: Baseline to 96 weeks ]
    To measure the effect of the proposed intervention on markers of vitamin D and bone metabolism, inflammation and HIV disease status.
