The outcome in myasthenia gravis patients--an eight-year follow-up after finishing immunoabsorption therapy.

Eight years ago four patients suffering from myasthenia gravis (MG) type C and E according to Compston with failed drug therapy were treated three times (one patient 11 times) by protein A immunoabsorption (Immunosorba, Excorim, Fresenius Hemocare GmbH, StWendel, Germany). No further immunoabsorption treatments have been carried out. In addition, three patients were given a thymectomy.

Two cases of refractory endocrine ophthalmopathy successfully treated with extracorporeal immunoadsorption.

Endocrine ophthalmopathy (EO) is a severe disease entity that is characterized by retrobulbar swelling due to accumulation of glycosaminoglycans on an autoimmune basis. This disorder can lead to the loss of vision and often is resistant to conventional therapy. There is a relation to Graves' hyperthyroidism, but probably no close association.

Removal of immunoglobulins by a protein A versus an antihuman immunoglobulin G-based system: evaluation of 602 sessions of extracorporeal immunoadsorption.

Elimination of IgG can be achieved by extracorporeal immunoadsorption (IA) based on specific binding to either staphylococcal protein A (Excorim) or sheep polyclonal antibodies directed against human IgG (Therasorb). In 602 analyzed sessions of IA, elimination of IgG was 60% through 80% depending on the treated plasma volume, with no significant difference between the mentioned systems. However, the decrease of IgM and IgA was approximately 50% in the anti-IgG compared to 20-40% in the protein A system.
