Childhood vasculitis

Abstract

Abstract Vasculitis is a challenging disease for paediatricians. Certain vasculitides are quite common in children whereas others are much rarer compared with adults. The most common vasculitides in childhood are IgA-associated vasculitis (Henoch–Schönlein purpura) and Kawasaki disease, which are usually self-limiting vasculitides although children do develop complications as a result. We now have much better knowledge of how to manage these patients and prevent the deleterious complications. This review provides an up-to-date discussion on childhood vasculitides, including diagnosis, treatment and follow-up strategies, together with a comparison with vasculitides in adults. It also discusses the newly defined monogenic vasculitides that often present during early childhood.
