Oral anticoagulant thromboprophylaxis for Kawasaki disease

Hemostatic changes in vasculitides

The systemic vasculitides are an heterogeneous group of rare diseases characterized by inflammation and fibrinoid necrosis of blood vessel walls. Today it is well known that the inflammatory process characterizing vasculitides activates coagulation factors, inhibits anticoagulant factors, inhibits fibrinolytic processes, increases platelet activity and production and determines endothelial dysfunction. So far the mortality in vasculitides, even if falling, remains substantially high. Patients with vasculitic syndrome are at increased risk of developing atherosclerosis and in these patients prevalence of cardiovascular disease and cardiovascular events is higher than in the general population. Vasculitides can be associated with antiphospholipid syndrome. It is important to establish a strategy of antithrombotic therapy management in vasculitic patients, but this has not yet been clearly achieved.
