Campylobacter jejuni infection has been implicated in the pathogenesis of Guillain-Barré syndrome (GBS) due to production of humoral immune response against neural antigens. A case-control study was performed in a tertiary care teaching hospital for the estimation of anti-ganglioside antibodies in GBS patients and their controls. Blood samples were collected from 59 GBS cases, 58 neurological controls (NC) and 60 non-neurological control (NNC) patients for automatic estimation of IgG and IgM antibodies to seven gangliosides using EUROLineScan software. Antibodies of IgG class for GM1 were highly significant in GBS (p = 0.000) and NC (p = 0.031) compared to NNC. However GBS group was not significant (p = 0.413) compared to NC. For GM2 ganglioside, GBS and NC groups were significant (p = 0.000) compared to NNC, but GBS group was not significant (p = 0.999) compared to NC. For GM3 ganglioside, GBS and NC groups were significant (p = 0.000) compared to NNC; but GBS group was insignificant (p = 0.858) compared to NC with similar trend for all other ganglioside antibodies. When IgM class of antibodies was evaluated for GM1, GBS group was not significant (p = 0.604) whereas NC group was significant (p = 0.000) compared to NNC. GBS group was not significant compared to NC (p = 0.011). The trend was the same for GM2 antibodies. For GM3, GBS group was significant (p = 0.010) and NC was near significant (p = 0.055) compared to NNC. However GBS group was not significant (p = 0.808) compared to NC. No groups were significant (p > 0.05) in relation to the remaining gangliosides except for GQ1b where GBS group (p = 0.001) and NC group were significant (p = 0.000) compared to NNC. GBS group was also significant (p = 0.001) compared to NC and NNC. Anti-gangliosides antibodies were present in highly significant levels in the GBS group, though they were also present in the non-paralytic neurological control patients compared to the non-neurological control group.
