Primary Outcome Measures:
  • Relapse rate within 1 year treatment; CDAI>220

Estimated Enrollment: 110
Study Start Date: September 2005
Estimated Study Completion Date: February 2008
Detailed Description:

Crohns Disease is an inflammatory disease of primarily the small intestine and colon.

In recent years scientists have hypothesized that low blood vitamin-D levels play a role in the development of autoimmune diseases, including Crohns disease. The purpose of this study is to examine whether vitamin-D is effective in keeping remission in inactive Crohns Disease (double blind placebo controlled trial). The patients who have active disease in the placebo group (reach primary endpoint), will in an open setting receive a higher single dose vitamin-D and the effect will be measured within 4 weeks.
