[Antiphospholipid autoantibodies and Covid-19]

Infection with Sars-CoV-2 is at the origin of a viral pandemic responsible for an unprecedented global health and economic crisis. Recently, an autoimmune process has been described in particular in severe forms of Covid-19. However, the role of autoimmunity in the disease remains to be defined. Thus, the presence of antiphospholipid autoantibodies (aPLs) is observed in patients with Covid-19 and a significant association is demonstrated between patients with a severe form and the presence of anticardiolipin autoantibodies (aCL) of IgG isotype.
