Description of a Cohort of Covid-19 Patients With a Circulating Anticoagulant

SARS-COV-2 infection is responsible for a potentially severe primarily respiratory infection called COVID19. A large proportion of patients, in particular in severe forms, present with thrombotic manifestations (DVT, EP, stroke, thrombosis of dialysis circuits, etc.). A significant proportion is also a carrier of circulating anticoagulant (ACC or LA), making it possible to suggest a diagnosis of APS. This type of autoantibody results in a spontaneous prolongation of the TCA uncorrected by a control serum therefore is quickly diagnosed using standard hemostasis The objective of this study is to describe the diagnosis of thrombotic complications in COVID19 patients presenting a positive lupus anticoagulant type test (LA) or aPL and the associated clinical and biological elements that may have favored thrombosis.
