Associations of Plasma Pentraxin 3 and Monocyte Chemoattractant Protein-1 Concentrations with Cardiovascular Disease in Patients with Chronic Kidney Disease

We examined the associations of circulating levels of pentraxin 3 (PTX3), monocyte chemoattractant protein-1 (MCP-1), and some other inflammatory mediators with cardiorenal syndrome. In advanced chronic kidney disease (CKD) patients (estimated glomerular filtration rate <30 mL/min/1.73 m²), the values of area under the curve of PTX3, tumor necrosis factor α, and high-sensitivity C-reactive protein for the detection of the association of cardiovascular disease (CVD) were 0.664, 0.507, and 0.318, respectively. In contrast, serum levels of MCP-1 were significantly higher in CKD patients than in control subjects independently of association with CVD.

Abstract

Both pentraxin 3 (PTX3) and monocyte chemoattractant protein-1 (MCP-1) are mediators of inflammation. They also appear to play critical roles in vascular endothelial dysfunction but their associations with cardiorenal syndrome remain largely unknown. The objective of this study was to examine their associations with cardiorenal syndrome. Circulating levels of PTX3, MCP-1, and some other biomarkers were evaluated in 134 patients with chronic kidney disease (CKD) and/or cardiovascular disease (CVD) and 55 age- and gender-matched subjects without CKD or CVD. Levels of PTX3, high-sensitivity C-reactive protein (hsCRP), and tumor necrosis factor α (TNFα) were significantly higher in CKD patients with CVD than in those without CVD. In advanced CKD patients (estimated glomerular filtration rate <30 mL/min/1.73 m²), the values of area under the curve of PTX3, TNFα, and hsCRP for the detection of the association of CVD were 0.664, 0.507, and 0.318, respectively. In contrast, serum levels of MCP-1 were significantly higher in CKD patients than in control subjects independently of association with CVD. PTX3, hsCRP, and TNFα, but not MCP-1 could predict the presence of CVD as a complication associated with CKD. Additionally, PTX3 might be a more sensitive marker for the association of CVD than hsCRP and TNFα in patients with advanced CKD.
