Antiganglioside antibody in patients with Guillain-Barré syndrome who show bulbar palsy as an initial symptom.

To identify valuable antiganglioside antibodies that support the diagnosis of Guillain-Barré syndrome (GBS) and its variants in patients showing bulbar palsy as an initial symptom.
Medical records of 602 patients with GBS or its variants were reviewed. Fifteen patients had bulbar palsy as an initial symptom. Serum antibodies against GM1, GM1b, GD1a, GalNAc-GD1a, GT1a, and GQ1b were examined in 13 of them.
Serum antiganglioside antibodies were positive in 11 (85%) patients. IgG anti-GT1a (n=8; 62%) and anti-GM1b (n=7; 54%) antibodies were often present, whereas all the patients had low or no anti-GM1 antibody activity. High anti-GD1a and anti-GQ1b IgG antibody titres were also present in some patients, but most had higher IgG antibody titres to GM1b or GT1a. All five patients with high IgG antibody titre to GM1b or GT1a only had had antecedent diarrhoea. Some patients with pharyngeal-cervical-brachial weakness (PCB) had IgG antibody to GT1a which did not cross react with GQ1b. Other patients with PCB had antibody to GT1a which cross reacted with GQ1b or antibody to GM1b, but anti-GM1b and anti-GT1a antibodies were not associated with the presence of bulbar palsy. All the patients who had no IgG antiganglioside antibodies recovered completely.
Measurement of serum IgG anti-GT1a and anti-GM1b antibodies gives helpful support for the diagnosis of GBS and its variants when there is early involvement of the oropharyngeal function independently of other neurological findings which appear as the illness progresses.
