91-OR: CTRP3, a Novel Adipokine with Anti-inflammatory and Cardioprotective Properties, in Patients with Cardiovascular Diseases and Type 2 Diabetes Mellitus

Cardiovascular diseases (CVD) are the most common cause of morbidity and mortality in patients with type 2 diabetes mellitus (T2DM). C1q TNF-related protein 3 (CTRP3) is a novel adipokine that reduces inflammation and acts cardioprotectively. The aim of our study was to analyze serum levels and gene expression of CTRP3 in subcutaneous and epicardial adipose tissue in patients with CVD and T2DM undergoing elective cardiac surgery. 38 patients with coronary artery disease (CAD) without T2DM (CAD group), 21 subjects with CAD and T2DM (T2DM group) and 18 patients with a valvular defect without CAD or T2DM (nonCAD group) were included into the study. Peripheral blood, subcutaneous (SAT) and epicardial adipose tissue (EAT) were examined at the start and end of elective cardiac surgery. mRNA expression was determined using qRT-PCR. 21 healthy subjects served as controls for serum CTRP3 (C group). Baseline anthropometric and biochemical parameters were comparable in all groups except of higher fasting blood glucose (6.0±1.2 vs. 5.5±0.2 vs. 6.0±0.9 vs. 8.5±0.4 mmol/l for CAD vs. nonCAD vs. C vs. T2DM, p To conclude, decreased serum levels of CTRP3 in patients with CVD together with reduced mRNA expression in EAT in T2DM subjects with CAD indicate a possible role of CTRP3 in the pathogenesis of cardiovascular complications of type 2 diabetes mellitus.
