Association of serum chemerin levels with the severity of coronary artery disease in patients with metabolic syndrome.


PMID 25664056

Abstract

The newly identified adipokine chemerin has been shown to be associated with the components of MetS, inflammation and insulin resistance. In this study, the relationship between serum chemerin levels and the presence and severity of coronary artery disease (CAD) was evaluated in patients with MetS. The study population consisted of 84 MetS patients (43 patients with CAD and 41 without CAD), who had coronary angiography for suspected coronary artery disease, and 46 healthy individuals as a control group. Angiographic CAD was defined as ≥ 50% luminal diameter stenosis of at least one major epicardial coronary artery. The severity of CAD was determined by the Gensini score. Serum chemerin levels were measured with enzyme linked immunosorbent assay (ELISA). Serum chemerin levels were significantly higher in patients with MetS (n=84) than those in the control group (120.47±25.32 vs. 90.4±11.4 ng/ml P < 0.001). In addition, MetS patients with CAD had higher chemerin levels than MetS patients without CAD (128.7±26.6 vs. 115.7±15.2 ng/ml, P < 0.001). Serum chemerin levels had a significant positive correlation with the Gensini score (r=0.58, P < 0.001). Multivariate logistic regression demonstrated that serum high-density lipoprotein cholesterol (HDL-C) and chemerin levels were significant and independent predictors for determining the presence of angiographic CAD (OR=1.009, 95% CI: 0.972-1.057; P=0.003 and OR=0.925, 95% CI: 0.896-0.922; P < 0.001, respectively). This study demonstrated that in patients with MetS, chemerin levels were higher in patients with CAD than patients without CAD and also showed a significant positive correlation with CAD severity.
