[Classification of MS and treatment strategy].
Japanese patients with relapsing-remitting multiple sclerosis (RRMS) consists of two groups. One is opticospinal form (OSMS), in which major neurological symptoms derive from optic neuritis and myelitis, and the other is conventional form (CMS) that shares similar genetical and clinical features with western type of MS. OSMS patients tend to experience disease relapses more frequently with the resultant severer neurological deficit than CMS ones. Both OSMS and CMS patients are treated with intravenous high-dose methylprednisolone in acute exacerbations, and plasmapheresis may be considered for those who do not respond to repeated intravenous steroids. For prevention of disease relapse, interferon-beta is effective; however, patients with long spinal cord lesion extending over three vertebral segments should be followed up with caution, as this finding indicates a risk of treatment failure.
