Peripheral neuropathy with gammopathy responding to plasmapheresis

Abstract

Two patients with subacute sensorimotor peripheral neuropathy were found to have benign gammopathies. They both responded to treatment by plasmapheresis. We suggest that a vigorous search for a paraprotein should be made in all undiagnosed patients presenting with peripheral neuropathy, including electrophoresis with isoelectric focusing. Plasmapheresis may be a treatment modality that should be explored in such cases.
