Therapeutic plasma exchange in neurology: 2012.

In treating neuroimmunological diseases, neurologists have a number of different drugs to choose from ranging from corticosteroids to IVIg to more specific cell based therapies, the latter most frequently from the world of oncology. In some diseases, therapeutic plasma exchange, a procedure rather than a drug, is used. The most obvious advantage of therapeutic plasma exchange is the usually rapid onset of action presumably due to removal of pathogenic auto-antibodies. In some diseases, a single course of therapeutic plasma exchange is used while in others prolonged treatment with therapeutic plasma exchange is used. This article will review the use of therapeutic plasma exchange in neurology and will draw heavily upon recent consensus statements from the American Society for Apheresis and the American Academy of Neurology and by Cochrane reviews.
