A case of chronic inflammatory demyelinating neuropathy associated with antibodies to gangliosides GM1 and GalNAc-GD1a



A case of chronic inflammatory demyelinating neuropathy associated with antibodies to gangliosides GM1 and GalNAc-GD1a



Rinsho Shinkeigaku 37(3): 228-232



In January 1993, a 43-year-old man was admitted to our hospital for left wrist-drop. Neurological examinations revealed asymmetrical distal weakness in the upper limbs. Deep tendon reflexes were normal in all 4 limbs. Sensory and autonomic nervous functions were intact. CSF examinations were within normal limits. Thin-layer chromatography with immunostaining revealed serum antibodies that reacted with GM1 and GalNAc-GD1a. Motor nerve conduction studies revealed abnormal temporal dispersion, and a low amplitude of compound muscle action potential in the left radial nerve. Neurological symptoms gradually improved with prednisolone over one and a half years. He was hospitalized again in January 1995, because of right wrist-drop and slight sensory loss of the limbs. Those findings were improved by methylprednisolone (1,000 mg/day) for 3 days. The interval until maximal disability in this patient was more than one month for each admission. This case must belong to inflammatory demyelinating neuropathy.
