LONDON—High-dose vitamin D as an add-on therapy may improve MRI outcomes in patients with relapsing-remitting multiple sclerosis (MS), according to a study presented at the 32nd Congress of the European Committee for Treatment and Research in MS.
“Vitamin D is the precursor of a potent immunoregulatory molecule. However, whether supplementation of it improves outcomes is uncertain, since existing medical evidence is contradictory and involves small patient numbers,” said Raymond Hupperts, MD, PhD, Professor of Neurology at Maastricht University in the Netherlands.
Previous studies have found an association between low serum levels of vitamin D and a greater risk of developing MS and poor MS outcomes. As a result, Dr. Hupperts and colleagues conducted the SOLAR (Supplementation of VigantOL Oil Versus Placebo as Add-on in Patients With Relapsing Remitting MS Receiving Rebif Treatment) study to investigate the effects of vitamin D as add-on therapy in patients receiving subcutaneous interferon beta-1a.
The SOLAR study included 229 patients who were stratified by serum vitamin D level and randomized to vitamin D or placebo.
