 This review summarizes the rationale and effects of immunoadsorption plasmapheresis for treating myasthenia gravis and lymphocytapheresis for multiple sclerosis.

 1. Plasmapheresis for treating myasthenia gravis

 For the treatment of severe myasthenia gravis (MG), plasmapheresis has been used for removing anti-acetylcholine receptor (AChR) antibodies. Its efficacy is widely accepted for the immediate control of myasthenic symptoms. We established a new method of plasmapheresis which more selectively and effectively removes AChR antibodies from the sera of MG patients and which has proven to be more cost effective due to the elimination of albumin replacement fluid. This method is based on a new adsorbent using tryptophan-conjugated polyvinyl alcohol resin (IM-T). Remarkable clinical improvement occurred in patients with myasthenia gravis after repeated long-term plasmapheresis using IM-T. The IM-T column has a higher efficiency for adsorbing anti-AChR antibodies from the plasma of myasthenic patients than does conventional plasmapheresis using a double filtration membrane or the centrifugation method.
