Study of Vitamin D Supplementation to Male HIV Sero-positive Patients

September 13, 2012 updated by: Ulrich Bang, Hvidovre University Hospital

The investigators want to investigate if HIV sero-positive males benefit from vitamin D supplementation. The study runs in 16 weeks and the participants are treated with one of three placebo controlled regimes (tablets):

  1. Calcium
  2. Calcium and 25-hydroxy-vitamin D
  3. Calcium and 25-hydroxy-vitamin D and 1,25-dihydroxyvitamin D

The endpoints are:

  • Serum vitamin D
  • Parathyroid hormone
  • ionized calcium
  • T-lymphocyte fractions (naïve, mature, Tregs)
  • Osteocalcin (bone metabolism)
