Guillain-Barré syndrome associated with acute hepatitis A.

A case of Guillain-Barré syndrome in a 49-year-old male is described. The syndrome presented as tetraplegia with sensory impairment and the pre-icteric phase of acute hepatitis A. Both viral hepatitis and neurologic disturbances improved, although neurologic changes lasted for 3 months after the onset. HA IgM antibody in cerebrospinal fluid was first manifest with onset of neurologic symptoms. On the basis of this finding and some reports in the literature it seems possible that the Guillain-Barré syndrome may be related to the immunopathogenetic mechanism of hepatitis A virus infection.
