Anti-ganglioside antibodies are consistently found in Guillain-Barré syndrome (GBS) patients from different geographical parts of the world. Several studies indicated differences in relative frequencies of anti-ganglioside reactivity and isotype distribution between GBS patients from Asia and from Europe. We investigated antibody reactivity against the gangliosides GM1, GM1b and GalNAc-GD1a in GBS patients from Japan and The Netherlands in two different laboratories. The proportion of GBS patients with anti-ganglioside antibodies did not differ between the two countries. GBS patients from The Netherlands more frequently had cross-reacting anti-GalNAc-GD1a/anti-GM1b antibodies and a stronger IgM anti-ganglioside response. Our findings indicate that geographical determined factors, dependent on either the host or the triggering infectious agent, determine the isotype distribution and fine specificity of anti-ganglioside antibodies in GBS patients.
