Immunological abnormalities in Kawasaki disease with coronary artery lesions.
A review of our previous immunological studies on Kawasaki disease (KD) was undertaken. The results showed that peripheral blood macrophages/monocytes, T-cells and B-cells become activated during acute KD in terms of numerical changes in immunocompetent cells, expression of activated antigens on the cell surfaces and cytokine production. Also, during acute KD with coronary artery lesions (CALs) the numbers of macrophages/monocytes are increased. In addition, both the increased levels of tumor necrosis factor-alpha and shed intercellular adhesion molecule-1 in serum are more evident in KD patients with CALs than in those without. Our results further suggest that the main characteristics of the pathogenesis of KD are increased numbers of peripheral blood macrophages/monocytes with the secretion of monokines by these activated cells, and the expression of adhesion molecules on immunocompetent cells. These immune responses develop more vigorously in KD patients with CALs.
