[The first Hungarian patient with Guillain-Barre syndrome after COVID-19]

Guillain-Barré syndrome (GBS) is a sporadic, relatively rare disease. In serious cases, it can lead to respiratory failure and death. The correlation between SARS-CoV-2 and the risk of GBS is not yet known. COVID-19-associated prolonged pulmonary complications could be worsened by the potential airway interference caused by GBS. The literature is inconsistent whether SARS-CoV-2 virus has direct or indirect effect on the onset of GBS. The authors describe the medical history of the first published GBS patient in Hungary with a preceding confirmed COVID-19 infection. The trigger role of COVID-19 infection is assumed because of the subsequent development of GBS after COVID-19 infection. So far none of the patients in the literature (including this patient) had positive PCR of SARS-CoV-2 virus from the cerebrospinal fluid.
