Antibodies to GD3, GT3, and O-acetylated species in Guillain-Barré and Fisher's syndromes: their association with cranial nerve dysfunction.
We examined serum antibodies to the four fetal antigens GD3, O-acetyl GD3, GT3, and O-acetyl GT3 ganglioside in patients with Guillain-Barré syndrome (GBS) or its variant Fisher's syndrome (FS). The patients with FS more often had significant IgG antibodies against GD3, GT3, and O-acetyl GT3 than did the healthy controls. Furthermore, anti-GD3 and anti-GT3 IgG antibodies were more often significantly present in the patients with FS than in those with GBS. IgG antibody to GD3, GT3, and O-acetyl GT3 had a significant association with the presence of ophthalmoparesis. These antibodies, however, cross-reacted with GQ1b and we detected no antibodies which specifically reacted with fetal gangliosides. In addition, oculomotor involvement was more closely related to IgG antibodies to GQ1b than to those to fetal gangliosides. No evidence was obtained that the serum antibodies to these fetal gangliosides are associated with specific neurologic signs of cranial nerves.
