[IgM antibody against sulfated glucuronyl paragloboside in a case of Guillain-Barré syndrome].

High-titer IgM antibody against sulfated glucuronyl paragloboside (SGPG) was detected in a case of Guillain-Barré syndrome. The patient recovered rapidly by the treatment with double filtration plasmapheresis and the anti-SGPG antibody was not detected on the 40th day of illness. Facial nerve palsy, however, lasted until the 6th month of illness. Anti-SGPG antibody might have the important role in the pathologic mechanisms of Guillain-Barré syndrome in this case.
