Autoimmune Aspects of Kawasaki Disease.

Authors: Sakurai Y Abstract Kawasaki disease (KD) is classified as a medium-sized vasculitis of systemic vasculitis syndrome characterized by hypercytokinemia. Although the etiology of KD remains unidentified, epidemiological features point to the role of infection and genetic predisposition. Recent studies revealed endothelial damage and resultant thrombin generation, as well as B-cell activation during the acute phase of KD. Several anti-endothelial cell autoantibodies (AECAs) have been identified in KD patients. Taken together with the recently developed concept of immunothrombosis, a potential pathogenic mechanism for KD emerges. First, some polyclonal antibodies generated against invading microorganisms would exhibit cross-reactivity toward endothelial cell components and beco...
