title: Sequential plasmapheresis and intravenous immunoglobulin therapy for refractory myasthenia gravis: case report.
abstract: Immunotherapy is currently the standard therapy for myasthenia gravis (MG) although some patients may be refractory to treatment. We describe the use of sequential plasmapheresis and intravenous immunoglobulin (IVIG) therapy for treatment of advanced MG in a patient refractory to all forms of medical treatment including corticosteroids, immunosuppressants, and intermittent plasmapheresis. The patient, a 37-year-old woman with systemic lupus erythematosus (SLE), had initially responded well to treatment with high dose corticosteroids and intermittent plasmapheresis, with the duration of response ranging from 3 to 4 months. However, after 18 months of therapy, the duration of response had gradually decreased to 1 month. She responded well to a 5 day trial of plasmapheresis followed by high dose IVIG, and the duration of response increased to 6 months. The SLE activity was relatively silent during each relapse. This report indicates the potential usefulness of sequential plasmapheresis and IVIG in the treatment of patients with refractory MG and SLE.
