Axonal pharyngeal‐cervical‐brachial variant of Guillain–Barré syndrome without Anti‐GT1a IgG antibody

Abstract
We report two cases of pharyngeal‐cervical‐brachial (PCB) variant of Guillain–Barré syndrome (GBS). The patients developed dysphagia and weakness of the neck and arms subsequent to Campylobacter jejuni infection. Oropharyngeal palsy recovered poorly. Electrophysiological findings demonstrated axonal conduction failure. Anti‐GD1a immunoglobulin G (IgG) antibody was detected in one case, and anti‐GM1b IgG antibody in another. Anti‐GT1a IgG and immunoglobulin M (IgM) antibodies were negative in both cases. The current cases suggest that the PCB and axonal variants of GBS form a continuous spectrum from the viewpoint of electrophysiological studies as well as antiganglioside serology.
