Serum antibodies to monosialoganglioside(GM1),disiologanglioside(GD1b),and Campylobacter jejuni,measured by enzyme-linked immunosorbent assay and serum antibodies to peripheral nerve myelin,measured by the C1 fixation and transfer assay,were studied in 58 acute-phase patients with Guillain- Barre syndrome(GBS),42 disease controls and 29 normal controls.Anti- peripheral nerve myelin antibodies were elevated in 57 of 58 patients with GBS compared with controls,whereas only 8.6%had increased antibody titers to GM1 and GD1b.Only low antibody titers(GM1)or no antibodies(GD1b)were found in controls.More GBS patients(17.2%)than controls(7%)had antibodies to C jejuni.Poor recovery with inability to walk at 1 year after onset of symptoms was seen in 3(5%)of the patients with GBS.All 3 patients had serological evidence of recent C jejuni infection but no antibodies to GM1 or GD1b.GBS patients with antibodies to GM1 or GD1b had excellent recovery.Our data indicate that antibodies to GM1 or GD1b do not necessarily mediate the extensive axonal damage seen in these severely affected patients. |
