Experience of treatment in critical Guillain‐Barre Syndrome case after COVID‐19 vaccination.

Background: The current study reported a case with a history of neuroradiculitis. Within 2 months of the COVID‐19 vaccine, critical Guillain‐Barre Syndrome (GBS) appeared after acute diarrhea, progressive myasthenia, and sudden respiratory and cardiac symptoms. Methods: The syndrome was addressed with measures, such as endotracheal intubation and cardiopulmonary resuscitation vasoactive drugs. Next, we conducted six cycles of human immunoglobulin treatment (dose of 400 mg/kg·d intravenously for 5 days consecutively) and three times plasma exchange (PE, 30 ml/kg), followed by methylprednisolone sodium succinate. Rehabilitation training was carried out continuously. Results: The consciousness of the patient returned to normal, wherein he carried out normal communication. The muscle strength recovered gradually but still could not stand independently. Presently, he is recovering at home. Conclusions: For patients with previous radiculitis, COVID‐19 vaccination may increase the susceptibility to GBS. Thus, it is recommended to extend the vaccination interval for these patients and ensure that any potential increased risk is continually assessed. [ABSTRACT FROM AUTHOR]
