Plasma exchange (PE) has been one of the most powerful treatments for patients with myasthenia gravis (MG) since Pinching et al. reported its clinical usefulness in 1976, despite the need for supplemental human plasma. However, new apheresis techniques, e.g., plasma adsorption (PA) and double filtration plasmapheresis (DFPP), which do not need human plasma, were developed and have been introduced for clinical use in MG. We compared the effects of these plasma purification therapies in patients with MG and found that DFPP improved such subjective symptoms as chest compression and general fatigue better than PA while both of them could decrease the serum level of acetylcholine receptor (AChR) antibodies and relieve objective muscle weakness to a similar degree. It may be that DFPP can remove some circulating pathogenic factors other than AChR antibodies more efficiently than PA.
