  Purpose

Several studies have shown that bone mineral density (BMD) at the femoral neck decreases with increasing physical handicap (EDSS-score) in MS patients. Possible explanations are less weightbearing exercise or less UV-exposure resulting in reduced vitamin D generation in the skin. Prevention of osteoporosis is a high priority, because treatment of the established disease remains sub-optimal.

We have designed a double-blind randomised controlled trial of two years' duration including 90-100 persons with MS age 18-50 to assess whether supplementation with vitamin D, given as a weekly dose of 20,000 IU cholecalciferol, can prevent bone loss.

The primary objective of this study is to determine changes in BMD over the 2 year study period comparing treatment and placebo groups.

The most important secondary objective is to determine cytokine profiles in blood samples. We will also assess parameters related to vitamin D status and physical performance.

Primary Outcome Measures:
  • Changes in BMD over the 2 year study period comparing treatment and placebo groups [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Cytokine expression following vitamin D supplementation [ Time Frame: 2 years ] [ Designated as safety issue: No ]

  • Changes in parameters of lower extremity function over the 2 year study period [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • The number of relapses, the time to first relapse, the number of relapse-free patients [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • The number of patients without progression of disability judged by EDSS and [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Reported infections [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • Ratings on a fatigue scale [ Time Frame: 2 years ] [ Designated as safety issue: No ]
