To determine the correlations between changes in high-density lipoprotein cholesterol (HDL-C) and other blood variables during the acute phase of Kawasaki disease (KD), we investigated changes in the plasma level of HDL-C, serum apolipoproteins and number of peripheral blood monocytes. 26 Japanese patients with KD were subjects of this study. Plasma HDL-C decreased during the 1st week of illness, and increased during the 2nd week. The mean levels of minimum HDL-C in KD patients treated with total intravenous immunoglobulin (IVIG) dose ≧ 4g/kg, was significantly lower than those treated with total IVIG dose < 4g/kg (p=0.0005). There was a strong direct correlation between minimum HDL-C in KD patients and HDL-C on 5th day of KD onset (r=0.71, p < 0.0001). Assessing the performance of plasma HDL-C on 5th day of KD onset in predicting the necessity for high-dose IVIG treatment to KD, ROCs were plotted and the AUC was 0.82. A cutoff value of 16mg/dl had a specificity of 0.82 and sensitivity of 0.80 for predicting those.

The apo A-I and A-II levels were correlated with plasma HDL-C, respectively. And the peripheral blood monocytes counts which correlated with serum levels of macrophage-colony stimulating factor, were not correlated with plasma HDL-C.

Plasma HDL-C levels during the 1st week of illness might serve as a predictor for non-responder to low-dose IVIG treatment in patients with acute KD.
