Thrombosis risk factors in ANCA-associated vasculitis

Abstract

The article presents a review of current data on arteriovenous thrombosis risk factors in antineutrophil cytoplasmic antibody-associated vasculitis (AAV). Thrombotic complications are among the most frequent prognostically unfavorable factors in AAV. In general, patients with AAV are at greater risk of mortality from cardiovascular events compared with the general population and patients with other forms of systemic vasculitis. Understanding the mechanisms of thrombosis, as well as pathogenic factors that cause an increased risk of arterial and venous thrombosis in AAV, can improve the quality of management of these patients. Therefore, the question of the need for primary and secondary prevention of thrombosis in AAV is of great practical importance. The presented data show the need to estimate the probability of thrombosis in patients with AAV, taking into account risk factors, as well as the influence of the disease itself and ongoing therapy. Assessment of the risk of thrombosis (both venous and arterial) is necessary for the timely administration of adequate preventive treatment of thrombotic complications in AAV.
