Coagulopathies, thrombotic risk and anticoagulation in COVID-19

Abstract

Clinical observations indicate that COVID-19 often provokes coagulopathies, which have been associated with high morbidity and mortality rates. These coagulopathies likely result from Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection-elicited systemic inflammation and endothelial damage. Patients with severe COVID-19 are at high risk of venous and arterial thromboembolic diseases; they can also develop disseminated intravascular coagulation in the most advanced stages of the disease. Medical Organisations on Thrombosis and Hemostasis, among which the Belgian Society on Thrombosis and Haemostasis (BSTH), have formulated recommendations for the prophylaxis and treatment of COVID-19-related venous thromboembolism in ambulatory and hospitalised patients, as well as for the anticoagulation of COVID-19 patients in need of long-term anticoagulation for unrelated cause.These recommendations provide every hospital and primary care physicians with an easy-to-use clinical guidance; they mainly rely on limited level of evidence and are likely to evolve with knowledge of COVID-19 pathophysiology and availability of data from ongoing clinical trials.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
