Clinical Trial Summary

In patients with Relapsing Remitting Multiple Sclerosis (RRMS), the investigators observed a positive correlation between regulatory T cell (Treg) function and vitamin D status. The present goal is to assess whether Treg function improves on supplementation with vitamin D3.


Clinical Trial Description

In several studies, Multiple Sclerosis (MS) incidence and disease activity has been related with vitamin D status. We observed that RRMS patients who remained relapse free before blood collection had a better vitamin D status than patients who experienced relapses (Smolders et al. Mult Scler 2008;17:1220-1224). Since vitamin D3 is a potent promotor of T cell regulation in vitro (Smolders et al. J Neuroimmunol 2008;194:7-17), we hypothesised that a promotion of Treg function in MS patients might underlie its association with MS disease activity. In a cohort of RRMS patients, we observed a positive correlation of Treg function with vitamin D status (Smolders et al. PLoS ONE 2009;4:e6635). Furthermore, vitamin D status correlated positively with a Th1/Th2-balance which was more directed towards Th2. In the present study, we will assess whether treatment of RRMS patients with vitamin D3 promotes T cell regulation.

In the present study, RRMS patients will be supplemented with vitamin D3, and regulatory T cell tests will be performed before and after supplementation. ;
