RT Journal Article T1 Dietary Mg Supplementation Decreases Oxidative Stress, Inflammation, and Vascular Dysfunction in an Experimental Model of Metabolic Syndrome with Renal Failure A1 López Baltanás, Rodrigo A1 Canalejo Raya, Antonio A1 Muñoz Castañeda, Juan R. AB Background: Metabolic syndrome (MetS) and chronic kidney disease (CKD) are commonlyassociated with cardiovascular disease (CVD) and in these patients Mg concentration is usuallydecreased. This study evaluated whether a dietary Mg supplementation might attenuate vasculardysfunction through the modulation of oxidative stress and inflammation in concurrent MetS andCKD. Methods: A rat model of MetS (Zucker strain) with CKD (5/6 nephrectomy, Nx) was used.Nephrectomized animals were fed a normal 0.1%Mg (MetS+Nx+Mg 0.1%) or a supplemented 0.6%Mg(MetS+Nx+Mg0.6%) diet; Sham-operated rats with MetS receiving 0.1%Mg were used as controls.Results: As compared to controls, the MetS+Nx-Mg0.1% group showed a significant increase inoxidative stress and inflammation biomarkers (lipid peroxidation and aortic interleukin-1b and-6 expression) and Endothelin-1 levels, a decrease in nitric oxide and a worsening in uremia and MetSassociated pathology as hypertension, and abnormal glucose and lipid profile. Moreover, proteomicevaluation revealed changes mainly related to lipid metabolism and CVD markers. By contrast, inthe MetS+Nx+Mg0.6% group, these parameters remained largely similar to controls. Conclusion: Inconcurrent MetS and CKD, dietary Mg supplementation reduced inflammation and oxidative stressand improved vascular function.
