title: Plasma clusterin levels in predicting the occurrence of coronary artery lesions in patients with Kawasaki disease.
abstract: Kawasaki disease (KD) is the leading cause of acquired heart disease during childhood in the developed countries. Coronary artery lesions (CAL) are the major complications of KD. A unique proteomic profiling with increased or decreased fibrinogen, alpha-1-antitrypsin, clusterin, and immunoglobulin free light chains were noted in KD in our previous study. The purpose of this study was to evaluate relations between these biomarkers and CAL in KD and to establish within the markers the appropriate cut-off value with which to predict the occurrence of CAL. A total of 47 KD patients were enrolled, including 14 with CAL and 33 without CAL. Plasma samples from patients with KD before intravenous immunoglobulin administration were indicated for measurement of these biomarkers. A potential relation among CAL, clinical characteristics, and these biomarkers was investigated, and a receiver operating characteristic curve was used to identify a cut-off value of the significant marker that best predicated the occurrence of CAL. Among these biomarkers, only plasma clusterin level was associated with the occurrence of CAL. Using a cut-off value of clusterin <12.0 mg/l, the relative risk for CAL was 4.53-fold (95% confidence interval [CI] 1.060-19.347%, P = 0.014). Results from this study suggest that plasma clusterin level <12.0 mg/l in KD is significantly associated with the occurrence of CAL. Results from this study provide a potential biomarker of KD that may help predict the occurrence of CAL.
