Chronic Idiopathic Demyelinating Polyneuropathy (Cipd):
Chronic, spontaneous loss or destruction of myelin. Myelin is a soft, white, somewhat fatty material that forms a thick sheath around the core of myelinated nerve fiber. Patients show progressive, usually symmetric weakness in the upper and lower extremities. Patients with clinical progression of the syndrome after 4 to 6 weeks by definition have CIPD. Treatment in most centers consists of giving IV-immune globulin for 4 to 5 days or plasmapheresis (5 to 6 exchanges over 2 weeks).
