title: [Association of IgA anti-GM1 antibody with antecedent diarrhea in patients with Guillain-Barré syndrome].
abstract: IgA has an important role in the gastrointestinal immune system. We investigated IgA anti-GM1 antibodies in Guillain-Barré syndrome (GBS) subsequent to diarrhea. IgA anti-GM1 antibodies were detected more often in GBS patients with a history of antecedent diarrhea than in those without that. Between the GBS patients with a history of prior symptoms of upper respiratory tract infections and those without that, we found no difference of the frequency of increased IgA anti-GM1 antibody titers. Six GBS patients who had antecedent symptoms of upper respiratory tract infections had IgA anti-GM1 antibodies. However, 5 patients of them also had a history of antecedent diarrhea. Our findings show that IgA anti-GM1 antibodies are associated with GBS following diarrhea.
