It remains unclear whether vitamin D insufficiency, which is common in individuals with multiple sclerosis (MS), has an adverse effect on MS outcomes. To determine whether serum concentrations of 25-hydroxyvitamin D (25(OH))D, a marker of vitamin D status, predict disease activity and prognosis in patients with a first event suggestive of multiple sclerosis (MS) (clinically isolated syndrome [CIS]). BENEFIT was a randomized trial originally designed to evaluate the impact of early- versus delayed-interferon beta-1b (IFNB-1b) treatment in patients with CIS. Serum 25(OH)D concentrations were measured at baseline, 6, 12, and 24 months. 465 of the 468 patients randomized had at least one 25(OH)D measurement, and 334 patients had both 6 and 12 months (seasonally asynchronous) measurements. Patients were followed for 5 years clinically and by MRI. MRI: New active lesions, increased T2 lesion volume, and brain volume. Clinical: MS relapses and disability (EDSS). Higher 25(OH)D levels predicted reduced MS activity and slower rate of progression. A 50 nmol/L (20 ng/mL) increment in average serum 25(OH)D levels within the first 12 months predicted a 57% lower rate of new active lesions (p=0·0009), 57% lower relapse rate (p=0·03), 25% lower yearly increase in T2 lesion volume (p=0·00004), and 0·41% lower yearly loss in brain volume (p=0·07) from month 12 to 60. Similar associations were found between 25(OH)D measured up to 12 months and MS activity or progression from month 24 to 60. In analyses using dichotomous 25(OH)D levels, values >= 50 nmol/L (20 ng/mL) up to 12 months predicted lower disability (EDSS = −0·17; p=0·004) during the subsequent 4 years. Among MS patients mainly treated with IFNB-1b, low 25(OH)D levels early in the disease course are a strong risk factor for long term MS activity and progression.
