MCP-1 and soluble TWEAK levels are independently associated with coronary artery disease severity in patients with chronic kidney disease

Abstract

Purpose: Patients diagnosed with chronic kidney disease (CKD) have a greater rate of cardiovascular mortality when compared with the general population. The soluble form of TNF-like weak inducer of apoptosis (TWEAK) and monocyte chemoattractan protein 1 (MCP-1) play important roles in cellular proliferation, migration and apoptosis. The current study aimed to analyze whether soluble TWEAK (sTWEAK) and MCP-1 levels are associated with the severity of coronary arterial disease (CAD) in CKD patients. Methods: Ninety-seven patients diagnosed with CKD stages 2–3 according to their estimated glomerular filtration rate and the presence of kidney injury were included in the study. Plasma sTWEAK and MCP-1 concentrations were determined using commercially available ELISA kits. Coronary angiographies were performed through femoral artery access using the Judkins technique. Results: Correlation analysis of sTWEAK and Gensini scores showed significant association (p < 0.01, r2 = 0.287). Also significant correlation has been found in MCP-1 levels and Gensini scores (p < 0.01, r2 = 0.414). When patients were divided into two groups with a limit of 17 according to their Gensini score, sTWEAK levels indicated a statistically significant difference (p < 0.01). Conclusions: Our findings support a relationship between sTWEAK and MCP-1 levels and CAD in CKD stages 2–3 patients.
