Neurologic indications for therapeutic plasma exchange: an update.

Neurologists commonly use therapeutic plasma exchange (TPE, also known as plasmapheresis or therapeutic apheresis) to treat a number of conditions. This concise review examines the most common neurologic indications for therapeutic plasma exchange. It focuses on Guillain-Barrè syndrome and myasthenia gravis and also the role of TPE in chronic inflammatory demyelinating polyneuropathy, Lambert-Eaton syndrome, multiple sclerosis, neuromyelitis optica, paraproteinemic polyneuropathy, and Sydenham's chorea. As with any treatment, the proven efficacy, cost, side effects, and availability must be considered before initiation of therapy.
