Can Vitamin D Supplementation in People With Crohn's Disease Improve Symptoms as an Adjunct Therapy? — D-CODE  

Crohn Disease Clinical Trial

Official title:
Can Vitamin D Supplementation in People With Crohn's Disease Improve Symptoms as an Adjunct Therapy? D-CODE Feasibility Randomised Controlled Trial

Clinical Trial Summary

There are around 115,000 people in the United Kingdom suffering with Crohn's Disease (CD). CD can cause inflammation and ulcers to develop anywhere within the gut. Symptoms of the disease include diarrhoea, abdominal pain and nutritional problems including vitamin D deficiency. Around half of people with CD are likely to have vitamin D deficiency. Research has shown that treating vitamin D deficiency in people with CD might help to improve the symptoms of the disease. However, there are no clear guidelines on how to detect or treat vitamin D deficiency in people with CD.

There will be two parts to the planned research involving three hospitals in Birmingham. Part 1 is a vitamin D screening study, where adults will be asked to have a finger-prick blood test to check their vitamin D levels. They will complete short diet and lifestyle questionnaires. Adults found to have vitamin D deficiency in part 1 may be invited to join part 2 of the research. Part 2 is a vitamin D supplementation study where participants will be given a daily vitamin D capsule to take by mouth for 6 months. They will be randomly allocated to 2 different groups with each group receiving a different dose of vitamin D. Participants will have blood tests at the start, after 3 months and after 6 months. They will complete quality of life questionnaires at the start and after 6 months. The last appointment will be a final follow up appointment after 9 months.

This research is important to help determine:

- Which dose of vitamin D is most effective at treating vitamin D deficiency in people with CD

- If symptoms of CD improve when vitamin D deficiency is treated.
