摘要: Past sun exposure and vitamin D supplementation have been associated with a reduction in the risk of MS. We measured serum concentration 25-hydroxyvitamin (25[OH]D) at time MS diagnosis 40 patients controls. found no difference levels 25(OH)D between controls when all samples or obtained during winter months were compared, but had significantly lower concentrations June to September than The stores adequate for bone metabolism (> 37 nmol/L) 70% throughout year within hypovitaminosis level (< 30% some year. During MS-relapses, remission, mostly reference range observed relation normal metabolism. conclude that most are their However, relapses remission suggest could be involved regulation clinical disease activity optimal immune responses remain determined.
