The frequency of presence of anti-myelin antibodies in patients with NMO was significantly higher than that in healthy and diseased controls. The expanded disability status scale scores correlated with the titers of the anti-myelin antibodies. Patients with anti-myelin antibody exhibited other autoantibodies significantly more frequently than patients without the antibody. Anti-myelin antibodies may be useful markers for predicting severe clinical courses in patients with NMO.展开更多
