Abstract
To determine disturbances of lipid metabolism in patients with Kawasaki disease, we investigated changes in the serum levels of apolipoproteins and serum lipids. Results were as follows. Total serum cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C) decreased during the early stage of Kawasaki disease. The apo A-I and A-II levels were low until the 2nd week of illness. Apo B decreased during the 1st week of illness, but rose slightly during the 2nd and 3rd weeks. The apo B/apo A-I ratio and the apo B/TC ratio were high in the early stages of illness. The group of patients with coronary artery lesions showed low levels of TC and HDL-C, and low levels of apo A-I, A-II and B during the early stages, compared with the group without coronary artery lesions. The apo B/TC ratio was significantly higher in the patients with coronary artery lesions during the 2nd week of illness. Our findings suggest an association between changes in serum lipids and apolipoproteins and coronary artery involvement in Kawasaki disease. These abnormalities may indicate the presence of early coronary arteriosclerosis.
