N2 - Selenium (Se) is an essential micronutrient for human health that protects from oxidative damage. Se deficiency has been associated with the development of cardiovascular diseases (CVD). In this study we aimed to investigate the association between Se status, CVD risk, cardio-metabolic and inflammatory markers in elderly population. Se Plasma levels and inflammatory markers [neutrophil/lymphocyte ratio, serum C-reactive protein (CRP) levels and Copper/Zinc ratio (Cu/Zn)] were measured in 858 control subjects (mean age 73.4 ± 9.3) and 606 CVD patients (mean age 72.5± 8.7). A multivariate logistic regression was performed to evaluate the association between Se deficiency (Se< 60 μg/L) and the risk of CDV. In a subgroup of 46 CVD patients the gene expression of IL-1β, CCL5/RANTES, IL-6, IL-8, IL-10, platelet-derived growth factor-β (PDGFβ) and sirtuins in peripheral blood mononuclear cell (PBMC) were further examined. Increased values of neutrophil/lymphocyte ratio, CRP levels and Cu/Zn ratio were observed in Se deficiency condition both in controls and in CVD patients. Moreover, enhanced gene expression of cytokines and chemokines such as IL1β, CCL5 and PDGF- β, and a downregulation of SIRT-1, SIRT-5, SIRT-6, SIRT-7 were found in PBMCs from CVD patients with Se deficiency. A multivariate logistic regression showed that Se deficiency was associated with an increased CVD risk (odds ratio = 1.946, 95% CI: 1.19–3.18, p < 0.01). The current study revealed that Se deficiency is independently associated with CVD, and with elevated circulating inflammatory markers and affects the expression of cytokines, chemokines and sirtuins in PBMCs.
