血浆置换在神经系统疾病中的应用进展

血浆置换是一种常用的血液净化方法,包括全血浆置换、双重血浆置换和免疫吸附等不同方法.许多神经系统疾病存在体内异常抗体水平的增高.如吉兰-巴雷综合征是因抗神经系统抗体引起脱髓鞘病变,重症肌无力由于乙酰胆碱受体抗体异常升高所致,慢性炎症性脱髓鞘性多发性神经病存在免疫介导过程等.血浆置换可以有效清除体内异常增高的抗体,迅速改善患者的临床症状、缩短病程.

Progress of plasma exchange in treatment of nervous system diseases

Plasma exchange is a commonly used blood purification method, h includes plasma exchange,double filtration plasmapheresis and immunoadsorption.Many nervous system diseases have the antibody. Guillian-Barre syndrome is caused by antibodies of the nervous system demyelinafing disease; Myasthenia grads is caused by the acetylcholinc receptor antibodies. CIDP also has autoimmune-mediated mechanism. Plasma exchange can be apphed effectively to remove antibodies, and to quickly improve the patient' s clinical symptoms and shorten the course of disease.
