Myasthenia gravis: treatment with plasma exchange experiences over 10 years.

Evaluation of the results of plasmapheresis therapy is reviewed on 160 patients suffering from myasthenia gravis. This new therapeutical procedure is considered very valuable: improvement can be achieved in 63% of the patients during the therapy, a further improvement in 30% after it. Plasmapheresis is especially effective for patients in respiratory crisis-prone state, for drug-resistant cases and for preparation patients for surgery. Plasma exchange therapy may be combined with other forms of immunosuppression with benefit. Thymectomy and plasma exchange are considered to be the main therapeutical procedures in myasthenia gravis.
