Allergies Are Associated with Increased Disease Activity in Multiple Sclerosis

Studies exploring the association between allergic diseases and the risk of developing multiple sclerosis (MS) have shown conflicting results.  A population based case control study in northern Italy showed that patients reporting history of atopic allergies had a decreased risk of MS compared to those reporting no history of allergies.  On the other hand, a case control study nested in the Nurse’s Health Study I and II showed no association between history of allergy and MS risk. This lack of association was also reported in a meta–‐analysis of 10 observational studies. However, the association between allergies and MS activity has not been investigated.  To download the research abstract, CLICK HERE
