Recurrent Anti-GQ1b Antibody Syndrome

ABSTRACT

Anti-GQ1 antibody is found in patients with Miller-Fisher syndrome (MFS), atypical MFS, and Bickerstaff's brainstem encephalitis (BBE). These conditions are various manifestations of post-infectious autoimmune disorders, and anti-GQ1b antibodies play a core pathogenic role. So they are referred as the 'anti-GQ1b antibody syndrome'. We report two cases of recurrent anti-GQ1b antibody syndrome.
