Fulminant Guillain-Barré syndrome showing severe pharyngeal-cervical-brachial weakness in the recovery phase: A case report

Abstract

Background: Fulminant Guillain-Barré syndrome (GBS) is characterized clinically by rapid progression of severe symptoms, such as the absence of brainstem reflexes, complete tetraplegia and respiratory arrest. The clinical course of fulminant GBS remains unclear. Here, we report a patient with fulminant GBS, who showed severe weakness of the pharyngeal-cervical-branchial (PCB) area in the recovery phase. Case presentation: A 38-year-old man rapidly developed fulminant GBS. In blood examination, he was positive for a broad range of anti-ganglioside antibodies, including anti-GQ1b, GT1a, GT1b, GD1a, GD1b and GD3 IgG antibodies. We performed immunosuppressive therapies using intravenous immunoglobulin and intravenous methylprednisolone. Although disturbance of consciousness and weakness of the distal upper and lower limbs improved gradually, weakness of the oropharynx, neck, and proximal upper limbs were resistant to these therapies. Anti-GT1a IgG antibodies remained persistently positive. Consequently, mechanical ventilation and tube feeding were required for 7 and 10 months, respectively. Two years later, weakness of the proximal upper limbs and mild respiratory dysfunction remained as sequelae. Conclusion: Anti-GT1a IgG antibodies are known to be detected in patients with the PCB variant of GBS. In fulminant GBS, the persistent presence of anti-GT1a IgG antibodies may be associated with occurrence of severe PCB-like weakness in the recovery phase.
