Childhood multifocal acquired demyelinating sensory and motor neuropathy

Abstract

We report the first pediatric cases of multifocal acquired demyelinating sensory and motor neuropathy with electrophysiologic evidence of proximal conduction abnormalities but no definite conduction block. Intravenous immunoglobulin caused clinical improvement followed by long-term remission without maintenance therapy; one patient has exhibited a monophasic course and the other has had a single relapse during the last 5 years. These cases suggest that there may be a long-term sustained beneficial effect of intravenous immunoglobulin therapy for children with this neuropathy.
