Circulating immune complexes and granulocytes chemotaxis in Kawasaki disease.

ABSTRACT

Serum immunoglobulin levels, complement titers, circulating immune complex levels, and chemotaxis of granulocytes were evaluated in 32 patients with Kawasaki disease with or without coronary aneurysm. The group of patients with coronary aneurysm showed relatively higher levels of IgG. Regardless of the presence of coronary aneurysm, the level of IgE in the acute phase was higher than that in the convalescent phase. The level of immune complexes was higher in the group of patients with coronary aneurysm (p less than 0.05). There was a low negative correlation between immune complexes and CH50. The chemotaxis of the patients with coronary aneurysm was significantly impaired (p less than 0.01).
