ANCA-associated vasculitis with recurrent thrombosis in a teenager after the new coronavirus infection

Abstract

ANCA-associated vasculitis is a rare disease in children characterized by multiple organ involvement. In recent years, there has been found a connection between systemic vasculitis, including ANCA-associated, and the new coronavirus infection. There are certain difficulties in the differential diagnosis of these conditions. In addition, patients with ANCA-associated vasculitis have a high incidence of venous thromboembolic complications, which creates additional difficulties in the diagnosis and treatment of this disease, especially in children. The article presents the current data review and a clinical case of ANCA-associated systemic vasculitis with damage to the kidneys, lungs, joints (microscopic polyangiitis) in a 17-year-old teenager after the coronavirus infection.
