Article:

Introduction: Covid-19 infection usually manifests with respiratory symptoms, but neurological signs might be the mean symptom revealing this infection such as Guillain Barre syndrome (GBS).COVID-19 associated GBS seems to be more severe than non-COVID-19 GBS. Case management: We reported a 49 old-man admitted in the intensive care unit for bilateral ascending symmetrical paresthesia associated with lower limb numbness and sphincter disorders two weeks after an upper respiratory infection. The diagnosis of post-Covid-19 GBS was maintained, and the evolution was favorable after Intravenous Immunoglobulin (IVIg) and plasma exchange (PLEX) as a second therapy. Conclusion: This case report suggest the probable causal link between COVID 19 and GBS. This severe association prompts us to do further research that may help professionals in an early diagnosis and early treatment thus improving morbidity and mortality.
