A 43-year-old male with 2 episodes of sensory impairments in four extremities and liver dysfunction, developed an acute exacerbation of both sensory impairments and liver dysfunction after administration of interferon-α. On admission, neurological examination revealed a mild distal weakness of four extremities, moderate impairment of superficial sensation in hands and severe impairment of deep sensation and areflexia in all extremities. Routine laboratory tests were normal except for a mild liver dysfunction. His serum was positive for antinuclear antibody, but negative for anti-DNA antibody and LE-test. Since he was seropositive for hepatitis B (HB) c antibody but seronegative for HBs antigen and antibody, HBe antigen and antibody, he was considered to be a seroconverted carrier of HB virus. Liver biopsy revealed chronic active hepatitis with marked lymphocytic infiltration. CSF examinations were within normal limits. Sensory conduction studies of median and sural nerves showed no response, but motor conduction studies of median and peroneal nerves were within normal limits. Light and electron microscopic examination of biopsied sural nerve disclosed a moderate decrease in large myelinated fibers, but not in either small myelinated or unmyelinated fibers. Thin-layer chromatography with immunostaining showed the presence of anti-GQ1b antibody in his serum. The anti-GQ1b antibody did not react with GT1a. Oral administration of prednisolone alleviated liver dysfunction, muscle weakness and superficial sensory impairment of four extremities, but not in deep sensation.
