Participant Flow

This research was conducted at 17 clinical sites, with accrual opening 10/2012. Due to budgetary constraints, accrual to protocol Version 1.0 was placed on hold 9/1/2013; follow-up visits for subjects on study continued while accrual was on hold. Version 2.0 opened to accrual on 2/2/2015. The study was closed to accrual on 6/3/1015.

Group A: Vitamin D3 50,000 IU
Subjects randomized to Group A will receive Vitamin D3 50,000 IU orally every four weeks by directly observed therapy (DOT). In addition all subjects receive a multivitamin (MVI) that contains ingredients not to exceed 600 IU of vitamin D3 and 200 mg of Calcium (Ca). Subjects will self-administer one MVI tablet orally once daily. Vitamin D3 50,000 IU: Group A: Vitamin D3 50,000 IU orally every four weeks by DOT

PRIMARY outcome

Timeframe: Baseline and wk 48

Population: Subjects who had baseline and wk 48 data. This includes subjects enrolled in v1.0, who completed wk 48 evaluations, but were prematurely discontinued before the wk 96 or Post-wk 48 visits and therefore not counted as having completed the study. Thus, the number analyzed may be greater than the number completed in the Participant Flow section.

Percent change from baseline to week (wk) 48 in DXA-measured BMD at the spine for the randomized study groups. Lumbar spine BMD (L1 - L4) (g/cm2) change from Baseline to wk 48 visit.

The Z-score is the standard deviation around mean bone mineral density in the lumbar spine, adjusted for sex, age, and race/ethnicity. An average Z-score of zero would be expected to be seen in healthy populations. A negative Z-score indicates lower than average bone mineral density. Low bone mineral density is a frequent finding in HIV-infected individuals, including adolescents and young adults.

The Z-score is the standard deviation around mean bone mineral density in the femoral neck, adjusted for sex, age, and race/ethnicity. An average Z-score of zero would be expected to be seen in healthy populations. A negative Z-score indicates lower than average bone mineral density. Low bone mineral density is a frequent finding in HIV-infected individuals, including adolescents and young adults.

HOMA-IR is calculated as fasting glucose (mg/dL) X fasting glucose (uIU/mL) / 405. An increase in HOMA-IR means that an individual has become more resistant (less sensitive) to the effects of insulin and thus would be a negative outcome. A reduction in HOMA-IR means that an individual has become more sensitive to the effects of insulin and would be considered a positive outcome.There are no set minimum or maximum scores for HOMA-IR, since it is based on measurements of insulin and glucose, the assays for which may vary. Several studies suggest a cut-off of \>2 for any insulin resistance, but "normal" values appear to vary greatly by population (https://www.mdcalc.com/homa-ir-homeostatic-model-assessment-insulin-resistance).

SECONDARY outcome

Timeframe: Week 24

Population: Subjects who had wk 24 data. This includes subjects enrolled in v1.0, who completed wk 24 evaluations, but were prematurely discontinued before the wk 96 or Post-wk 48 visits and therefore not counted as having completed the study. Thus, the number analyzed may be different from the numbers in the Participant Flow section.
