Evaluation of chemerin in acute coronary syndrome and its role in cardiodiabetics

Abstract

Objectives: Chemerin is a proinflammatory adipokine whose role in metabolic syndrome and insulin resistance is well known. Chemerin has shown to carry a good prognostic/predictive value in patients of Coronary Artery Diseases (both chronic as well as acute) in the studies done in the US and Europe. However, no such study has been reported from India. Hence, this study was undertaken to evaluate Chemerin in patients of Acute Coronary Syndrome (ACS) and assess their role in cardiodiabetic patients. Materials and Methods: We included seventy cases of ACS and further subdivided them into two groups - (1) with co-existing diabetes mellitus (ACS-DM) (n = 33) and (2) without co-existing DM (ACS-NDM) (n = 37). Thirty healthy age and sex matched controls were included for comparison. Chemerin levels were measured by ELISA, hs C Reactive Protein (hs CRP) by turbidimetric assay, Creatine Kinase MB (CK-MB) by immunoinhibition (IFCC method) and Troponin I (Trop I) by Chemiluminescent Microparticle immunoassay. All the data were analyzed using Social Science Statistics Calculators. Results: Serum Chemerin levels were highest in ACS-DM (0.80 ± 0.61 ng/ml) as compared to ACS-NDM (0.42 ± 0.22 ng/ml) and controls (0.25 ± 0.10 ng/ml). On comparison, the difference amongst all was statistically significant. Furthermore, Chemerin showed a positive correlation with all the three parameters of ACS – hs CRP, CK- MB and Trop I. Conclusion: Chemerin levels are markedly elevated in ACS patients, more so in those with coexisting diabetes [cardio diabetics]. Chemerin is a novel biomarker of ACS.
