About this study

Official title: Supplementation of Vitamin D3 (Cholecalciferol) in Patients With Inflammatory Bowel Diseases (IBD) and Hypovitaminosis D: A Prospective Randomized Controlled Trial.

This study aims to evaluate the effect of vitamin D3 supplementation on disease activity and quality of life in IBD patients deficient in vitamin D, and also help determine the optimal dose of vitamin D3 for them.

Hypothesis: Supplementation of vitamin D3 in IBD patients with hypovitaminosis D can improve their quality of life and decrease IBD activity.

Read the detailed description

The incidence of hypovitaminosis D has been reported to be as high as 75% in patients with IBD. However, it is unclear whether low vitamin D levels contribute to the pathogenesis of IBD or are a consequence of IBD. Recent animal data studies suggest that maintenance of the epithelial barrier integrity in the large intestine by vitamin D is important in preventing IBD.

However, more evidence is required to determine the effect of vitamin D3 supplementation in patients with IBD. Furthermore, there is no clear consensus regarding the appropriate dose of vitamin D supplementation in IBD patients.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Vitamin D3Dietary supplement

    Also called vitamin D3 cholecalciferol

    Study patients who took 2,000 IU daily of vitamin D3 will be compared to those who took 4,000 IU daily to determine the different effects of vitamin D3 dose on quality of life, disease activity, and the laboratory tests in this study.

What does the primary outcome measure?

vitamin D3 supplementation in IBD patients with hypovitaminosis D. (time frame: 90 days after patient taking the Vitamin D3 supplement daily). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01877577, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
