Palasma Exchange in Autoimmune Neurological Diseases

This systematic review and meta-analysis evaluates the effectiveness and safety of therapeutic plasma exchange (TPE) for treating autoimmune neurological diseases (ANDs). By analyzing 38 studies involving 2,199 patients, the research indicates that TPE leads to a high rate of clinical improvement across various conditions, including Guillain-Barré syndrome and myasthenia gravis. While age appears to influence the success rate—with younger patients showing better responses than those over 60—geographic region and specific disease types do not show statistically significant differences in efficacy. The study finds an all-cause hospital mortality rate of 4%, though these deaths are largely attributed to the progression of the underlying disease rather than the procedure itself. Common but manageable adverse events identified include hypotension, coagulation disorders, and infections. Ultimately, the authors conclude that TPE is a safe and beneficial intervention, though they call for more rigorous, multicenter trials to refine treatment protocols.
