What this Trial Is About
The investigators hypothesize that hypogammaglobulinemia (defined as IgG serum concentration \<7.0g/L) is a treatable cause of fatigue in people with MS: The primary objective is to prove the link between hypogammaglobulinemia and fatigue in patients with multiple sclerosis. The secondary objective is to show that fatigue is mediated via frequent infections in people with MS and hypogammaglobulinemia.
