EPIDEMIOLOGY OF HEMORRHAGIC VASCULITIS IN CHILDREN: PREVALENCE AND RISK FACTORS

Abstract

Hemorrhagic vasculitis ( IgA vasculitis ) is the most common form of systemic vasculitis in children and is a pressing problem in modern pediatrics due to its high incidence, variety of clinical manifestations, and risk of complications, primarily renal. Hemorrhagic vasculitis ( IgA vasculitis , Henoch - Schonlein disease) is one of the most common systemic vasculitides in childhood, characterized by immune complex-mediated damage to the microcirculatory vessels. The disease occurs primarily in preschool- and school-age children and manifests itself with lesions of the skin, joints, gastrointestinal tract, and kidneys. Despite significant advances in the study of the pathogenesis of the disease, hemorrhagic vasculitis remains a pressing problem in pediatrics due to the high frequency of relapses and the risk of complications.
