[A case of myeloradiculoneuropathy associated with persistent high titers of anti-GM1 and anti-GD1b antibodies].
A 60-year-old woman was admitted to our hospital with bilateral weakness of the lower limbs. She had been suffering from spastic paraparesis of unknown origin for 12 years since she was 48. Myelopathy with the Th6 level appeared when she was 52 and underwent gradual deterioration. On admission, she showed spastic paraparesis and myelopathy with the Th6 level. A thoracic spinal MRI examination revealed a wholly thin spinal cord. EMG demonstrated that the conduction velocity of the peroneal nerve was 37.8m/sec, and F waves were not evoked on stimulation of the peroneal nerve. Although the anti-GM1 and anti-GD1b antibody titers in the serum were increased on admission, their values decreased transiently after whole plasmapheresis. There was accompanying impairment of the radiculoneuropathy and myelopathy. It is important to measure the titers of anti-ganglioside antibodies in patients with myeloradiculoneuropathy of unknown origin, and whole plasmapheresis is considered to represent a useful treatment for this type of illness.
