Relationship between <i>Helicobacter pylori</i> infection and multiple sclerosis.

Abstract

<i>Hp</i> infection appears to be more frequent in MS patients. If confirmed, this might indicate either a common factor that causes susceptibilities to both MS and <i>Hp</i> infection or that <i>Hp</i> might be a causal factor for developing MS. If a causal link between <i>Hp</i> infection and MS is confirmed in the future, this may have a major impact on the pathophysiology and management of MS.
