Description

Neuromyelitis optica (NMO) is an inflammatory demyelinating disease of the central nervous system that causes severe optic neuritis and myelitis attacks. The association of NMO with serum autoantibody marker NMO-IgG was reported in 2004. The effectiveness of immunoabsorption plasma pheresis (IAPP) therapy for treating acute exacerbations of NMO has not been well evaluated; thus, accumulation of therapeutic experience for this disease is important. We report 2 patients with acute exacerbations of NMO spectrum disorders, although neither patient has demonstrated optic neuritis to date. Both patients were unresponsive to intravenous methylprednisolone therapy, but showed significant improvement after IAPP therapy, which allowed us to reduce the immunosuppressive medications. In conclusion, IAPP therapy may be one of therapeutic options for patients demonstrating a fulminant attack of NMO.
