Anti-hsp60 antibody responses based on Helicobacter pylori in patients with multiple sclerosis: (ir)Relevance to disease pathogenesis

J Neuroimmunol. 2016 Sep 15:298:19-23. doi: 10.1016/j.jneuroim.2016.06.009. Epub 2016 Jun 23.

Abstract

In view of published data suggesting that Helicobacter pylori (Hp) is a trigger of multiple sclerosis (MS), we assessed anti-heat shock protein 60 (hsp60)Hp antibody reactivity in 129 MS patients and 48 demograpically-matched healthy controls (HCs). Anti-Hp antibodies by ELISA were more elevated in MS than HCs but did not differ between different MS phenotypes. All anti-Hp-positive MS sera, irrespectively of their clinical phenotype, were anti-anti-hsp60 positive. Anti-hsp60 Hp seropositivity correlated with age at disease onset. In conclusion, anti-hsp60 Hp antibodies are present in all anti-Hp positive MS patients, and their relevance to disease pathogenesis is questionable.
