a case report of three guillain-barré syndrome during sars-cov-2pandemic: promising outcome in a patient with history of multiplesclerosis

Neurologic complications in patients with coronavirus disease 19 (covid-19) are common particularly in hospitalized patients. guillain–barré syndrome (gbs) is a rare complication of covid-19. most patients with gbs and covid-19 presented with progressive, ascending limb weakness evolving over one to four days. there are some reported cases of gbs, mostly in form of case reports or case series, and also a comprehensive review on this topic. however, none of these cases experienced multiple sclerosis (ms) as an underlying disease. so, in this manuscript we reported three cases of covid-19 induced gbs; one of them with history of ms and promising outcome after receiving five sessions of plasmapheresis and corticosteroid therapy
