title: Clinical and electrophysiological correlation in chronic inflammatory demyelinating polyneuropathy with intravenous immunoglobulin therapy: a case report.
abstract: The clinical effect of high-dose intravenous immunoglobulin (IVIg) is reported as correlated with electrophysiological study in a 15-year-old boy with chronic inflammatory demyelinating polyneuropathy (CIDP). Within three months the patient developed from progressive paraparesis to complete quadriplegia with relative preservative of sensory and bulbar functions. High dose IVIg with 0.4 gm/kg per day was given for five consecutive days, and recovery occurred during the first week, particularly in both the lower limbs. Maximal benefit was achieved by another course of IVIg treatment. The effect maintained for six weeks, but muscle power deteriorated rapidly one week later. Muscle power improved again after another two courses of IVIg infusion. Serial nerve conduction velocity studies showed an improvement in the distal latencies and the amplitudes of compound muscle action potentials (CMAPs) which were not, however, well correlated with the clinical improvement. No improvement in nerve conduction velocities was ever noted.
