Background: Nitric oxide (NO) is oxidative stress biomarker which is regarded as one of the key determinants of energy metabolism and vascular tone. Considering the controversial reports on the association between nitric oxide products (NOx) and metabolic syndrome (MetS), the aim of the current study was to examine that potential relationship. Additionally, we aimed to evaluate a broad spectrum of other oxidative stress biomarkers [i.e., malondialdehyde (MDA), advanced oxidation protein products (AOPP), xanthine oxidoreductase (XOD), xanthine oxidase (XO) xanthine dehydrogenase (XDH)] in relation with MetS. Methods: A total of 109 volunteers (46.8% of them with MetS) were included in this cross-sectional study. Biohemical and anthropometric parameters, as well as blood pressure, were obtained. The MetS was diagnosed according to the International Diabetes Federation criteria. Results: Multivariate logistic regression analysis showed that XOD (OR=1.011; 95% CI 1.002-1.019; p=0.016), XO ...(OR=1.014; 95% CI 1.003-1.026; p=0.016), MDA (OR=1.113; 95% CI 1.038-1.192; p=0.003) and AOPP (OR=1.022; 95% CI 1.005-1.039; p=0.012) were the independent predictors of MetS, whereas no association between NOx and MetS was found. As XOD rose for 1 U/L, XO for 1 U/L, MDA for 1 mu mol/L and AOPP for 1 T/L, probability for MetS rose for 1.1%, 1.4%, 11.3% and 2.2%, respectively. Adjusted R-2 for the Model was 0.531, which means that 53.1% of variation in MetS could be explained with this Model. Conclusions: Unlike XOD, MDA and AOPP, NOx is not associated with MetS.
