Abstract
Plasma exchange is a well-established therapeutic procedure commonly used in many neurological disorders of autoimmune etiology. It is thought that the beneficial effects of plasma exchange occur through the elimination of pathognomonic inflammatory mediators, including autoantibodies, complement components, and cytokines. In various neurological disorders, randomized controlled studies have demonstrated the efficacy of plasma exchange (eg, in Guillain-Barré syndrome and other forms of immune neuropathies). Although widely used, the potential benefit of plasma exchange in the treatment of multiple sclerosis, myasthenia gravis, and Lambert-Eaton syndrome is less clear.
