Oxidative stress is associated with the number of components of metabolic syndrome: LIPGENE study

Previous evidence supports the important role that oxidative stress (OxS) plays in metabolic syndrome (MetS)-related manifestations. We determined the relationship between the number of MetS components and the degree of OxS in MetS patients. In this comparative cross-sectional study from the LIPGENE cohort, a total of 91 MetS patients (43 men and 48women; aged between 45 and 68 years) were divided into four groups based on the number of MetS components: subjects with 2, 3, 4 and 5 MetS components (n¼20, 31, 28 and 12, respectively). We measured ischemic reactive hyperemia (IRH),plasma levels of soluble vascular cell adhesion molecule-1 (sVCAM-1), total nitrite, lipid peroxidation products (LPO), hydrogen peroxide (H2O2), superoxide dismutase (SOD) and glutathione peroxidase (GPx) plasma activities. sVCAM-1, H2O2 and LPO levels were lower in subjects with 2 or 3 MetS components than subjects with 4 or 5 MetS components. IRH and total nitrite levels were higher in subjects with 2 or 3 MetS components than subjects with 4 or 5 MetS components. SOD and GPx activities were lower in subjects with 2 MetS components than subjects with 4 or 5 MetS components. Waist circumference,weight, age, homeostatic model assessment-b, triglycerides (TGs), high-density lipoprotein and sVCAM-1 levels were significantly correlated with SOD activity. MetS subjects with more MetS components may have a higher OxS level. Furthermore, association between SOD activity and MetS components may indicate that this variable could be the most relevant OxS biomarker in patients suffering from MetS and could be used as a predictive tool to determine the degree of the underlying OxS in MetS.

Therapeutic approaches to decrease serum triglyceride (TG) concentrations are not successful mainly due to poor adherence or adverse effects of therapies. In consequence, the search for new low-cost and safer therapeutic alternatives is mandatory. Dark chocolate and cacao have shown promising results improving lipid profiles. Recently, using cacao by-products to reduce elevated cardiometabolic risk markers in an animal model of obesity induced by a high-fat diet and fructose, we showed that TGs, low-density lipoprotein cholesterol, and the TG/high-density lipoprotein (HDL) ratio decreased, suggesting that cacao by-products improved the metabolic function of obese animals. Based on these results, as a proof of concept, a blinded placebo-controlled study was implemented to explore the effects of cacao by-products on anthropometric and biochemical variables in a group of overweight subjects participating in a program composed of reduced-calorie-diet counseling plus a simple aerobic exercise plan. The results showed that counseling induced weight and abdominal circumference reductions in both groups. TGs did not change in the control group; however, TG decreased significantly by 54.9 mg/dL (27.9%) in the experimental group. The TG/HDL cholesterol ratio changed markedly (1.5) in the experimental group. The results reported suggest the use of cacao by-products as an alternative for the treatment of hypertriglyceridemia.
