Vasculitis in children.

Common vasculitic disorders in children include those associated with infections (e.g., Rickettsiae, subacute bacterial endocarditis), Schonlein-Henoch purpura, and Kawasaki disease. Recent advances have occurred in understanding the pathogenesis of vasculitides. In this review, the reader will be exposed to some of the developments in adhesion molecules, antineutrophil cytoplasmic antibodies, antiendothelial antibodies, and antiphospholipid antibodies. Classification criteria and diagnostic strategies are also summarized.
