GBS patients with antibodies to Gal-C tend to have demyelinating neuropathy. Subtype of GBS with both Gal-C and ganglioside antibodies remains controversial. Eight of 16 GBS cases with both antibodies (Gal-C-GS-GBS) were demyelinating type. None of the patients with Gal-C-GS-GBS exhibited axonal neuropathy. Coexistence of Gal-C and ganglioside antibodies may be associated with demyelination.
