Staphylococcal protein A (SPA) has a high affinity for human immunoglobulin, and SPA immunoadsorption can specifically reduce the titer of autoantibodies and quickly relieve the clinical symptoms of myasthenia gravis (MG). Recent studies have suggested that immunoadsorption has better clinical efficacy and a lower incidence of adverse reactions than plasma exchange. A case of refractory MG with poor response to corticosteroids, intravenous immunoglobulins and immunosuppressive therapy was reported. The patient had low immune function and progressive pulmonary infection in the later stage of the disease. Respiratory muscle weakness was relieved quickly after four times of immunoadsorption therapy. The value of immunoadsorption in the treatment of refractory MG was explored with literature review.
