title: Disulfiram neuropathy: a neurofilamentous distal axonopathy.
abstract: Disulfiram is used to treat alcoholism and is known to cause peripheral neuropathy: few reports of biopsied human nerves have revealed axonal degeneration and loss of myelinated fibers. We studied a 22-year-old woman with severe sensorimotor neuropathy following treatment with disulfiram for 6 months. Histologic studies of the sural nerve revealed a neurofilamentous axonopathy with rare enlarged axons distended by neurofilaments. Disulfiram is converted enzymatically to carbon disulfide, which causes neurofilamentous distal axonopathy in animals. Similar changes in human nerve after disulfiram administration suggest that carbon disulfide is the toxic agent.
