Case report: Hepatitis A preceding Guillain-Barré syndrome.

A case of acute hepatitis A with Guillain-Barré Syndrome subtype AMAN (acute motor axonal neuropathy) in a 17-year-old male is reported. Serum and cerebrospinal fluid were positive for anti-hepatitis A virus (HAV) IgM, IgG, and IgA. The onset of the syndrome was evident in week 3 of illness. The remarkably high titers of serum anti-HAV IgG appeared unique to a hepatitis A patient with the syndrome. Phylogenetic analysis of the HAV genome detected in the serum and feces revealed genotype IIIA, circulating commonly in Pune, western India.
