What have we learned about chronic inflammatory demyelinating polyradiculoneuropathyin the last twenty years ?

Abstract

chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) has been widely described during the last quarter of the twentieth century. The last 20 years have seen decisive progress in its understanding. The diagnostic criteria have been simplified and the steps of the diagnostic process have been clarified. The phenotypic contours of the disease are now well known, as are the diagnostic pitfalls. From a pathophysiological point of view, the discovery of autoantibodies directed against nodal and paranodal proteins has been a major advance, although it concerns only a minority of patients. These discoveries have a major impact on the therapeutic management of these patients, often suffering from a very active form of the disease. The next 20 years will surely see a further deepening of knowledge about this fascinating disease.
