Overview

Randomized trial evaluates vitamin D effects on disease activity in individuals with clinically isolated syndrome, suggesting a potential therapeutic role.

Key Points

This research aims to assess how increases in plasma vitamin D levels affect disease activity after a clinically isolated syndrome.
Participants were part of the D-lay MS Randomized Controlled Trial, focused on vitamin D supplementation.
Evaluated disease activity over 24 months, measuring relapses and MRI activity with new or contrast-enhancing lesions.
Increased plasma vitamin D levels resulted in a significant reduction in relapse rates.
MRI activity showed a decrease in new and contrast-enhancing lesions with higher vitamin D levels.
