Botswana Vitamin D Supplementation Study in HIV/AIDS

Phase 3
Completed
Conditions
HIV
Interventions
Dietary Supplement: 7000 IU/d D3 over 12 weeks
Dietary Supplement: 4000 IU/d D3 over 12 weeks
Registration Number
NCT02189902
Lead Sponsor
Children's Hospital of Philadelphia
Brief Summary

The goal is to determine the vit D supplementation dose that safely results in optimal serum vitamin D (25D) concentrations in HIV-infected children and adults living in Botswana. To do this the investigators will test two oral daily doses (4000 vs. 7000 IU) of cholecalciferol (D3) dietary supplement over a 12-week period in 60 children and adults with HIV/AIDS living in Botswana (5.0 to 50.9 yrs), to assess safety as determined by serum calcium and 25D concentrations and efficacy to replete vit D status as determined by achieving a minimum serum 25D concentration of 32 ng/mL (80 nmol/L).

Detailed Description

Many people living with HIV/AIDS in African countries are vit D deficient or insufficient. Vit D deficiency in HIV/AIDS may be due to low dietary vit D intake, increased requirements, malabsorption, specific drug therapies (antiretrovirals, in particular), reduced outdoor physical activity, reduced vit D synthesis from UV light exposure in dark skin pigmented individuals, or unknown HIV-associated factors. Vit D deficiency likely contributes to abnormal immune status and increased inflammatory state, and to poor growth, bone, and muscle function, and may contribute to risk for tuberculosis (TB) infection. The goal is to determine the vit D supplementation dose that safely results in optimal serum 25D concentrations in HIV-infected children and adults living in Botswana.

To do this the investigators will test two oral daily doses (4000 vs. 7000 IU) of cholecalciferol (D3) dietary supplement over a 12-week period in 60 children and adults with HIV/AIDS living in Botswana (5.0 to 50.9 yrs), to assess safety as determined by serum calcium and 25D concentrations and efficacy to replete vit D status as determined by achieving a minimum serum 25D concentration of 32 ng/mL (80 nmol/L).
