Abstract
Introduction Introduction: metabolic syndrome comprises a combination of diabetes, high blood pressure, and obesity, and metabolic associated fatty liver disease (MAFLD) is associated with it. Objective: to evaluate the effect of supplementation with S-adenosyl-L-methionine + N-acetylcysteine + thioctic acid + vitamin B6 (MetioNac®) for 3 months on lipidic and biochemical parameters in subjects with metabolic syndrome and at risk of MAFLD. The reduction in body weight and the oxidative stress markers malondialdehyde (MDA) and superoxide dismutase (SOD) were also evaluated. Methods: patients with metabolic syndrome, at risk of MAFLD (FIB-4 < 1.30), and with an indication for weight reduction were recruited (n = 15). Control group followed a semipersonalized Mediterranean diet (MD) for weight reduction, according to the recommendations of the Spanish Society for the Study of Obesity (SEEDO). Experimental group, in addition to the MD, took three capsules of MetioNac® supplement per day. Results: compared with the control group, subjects taking MetioNac® showed significant (p < 0.05) reductions in the levels of TG and VLDL-c, as well as in total cholesterol, LDL-c, and glucose levels. They also showed increased levels of HDL-c. Levels of AST and ALT decreased after the intervention with MetioNac®, but this decrease did not reach statistical significance. Weight loss was observed in both groups. Conclusion: supplementation with MetioNac® may be protective against hyperlipidemia, insulin resistance, and overweight among metabolic syndrome patients. Further studies on this issue are needed in a larger population.

Zelber-Sagi S, Ivancovsky-Wajcman D, Fliss-Isakov N, Hahn M, Webb M, Shibolet O, Kariv R, Tirosh O. Serum Malondialdehyde is Associated with Non-Alcoholic Fatty Liver and Related Liver Damage Differentially in Men and Women. Antioxidants (Basel) 2020; 9:antiox9070578. [PMID: 32630732 PMCID: PMC7401879 DOI: 10.3390/antiox9070578] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 06/16/2020] [Accepted: 06/25/2020] [Indexed: 12/14/2022] Open
Abstract
Background: Non-alcoholic fatty liver disease (NAFLD) and steatohepatitis (NASH) are associated with increased oxidative stress and lipid peroxidation, but large studies are lacking. The aim was to test the association of malondialdehyde (MDA), as a marker of oxidative damage of lipids, with NAFLD and liver damage markers, and to test the association between dietary vitamins E and C intake and MDA levels. Methods: A cross-sectional study was carried out among subjects who underwent blood tests including FibroMax for non-invasive assessment of NASH and fibrosis. MDA was evaluated by reaction with Thiobarbituric acid and HPLC-fluorescence detection method. NAFLD was diagnosed by abdominal ultrasound. Findings: MDA measurements were available for 394 subjects. In multivariate analysis, the odds for NAFLD were higher with the rise of MDA levels in a dose–response manner, adjusting for age, gender, BMI, and lifestyle factors. Only among men, higher serum MDA was associated of higher odds for NAFLD and NASH and/or fibrosis (OR = 2.59, 95% CI 1.33–5.07, P = 0.005; OR = 2.04, 1.02–4.06, P = 0.043, respectively). Higher vitamin E intake was associated with lower odds of high serum MDA level (OR = 0.28 95% CI 0.13–0.62, P = 0.002). In conclusion, serum MDA is associated with NAFLD and markers of NASH or fibrosis among men. Dietary vitamin E may be protective among women.

Protective effects of cichoric acid on H 2O 2-induced oxidative injury in hepatocytes and larval zebrafish models. Biomed Pharmacother 2018; 104:679-685. [PMID: 29803928 DOI: 10.1016/j.biopha.2018.05.081] [Citation(s) in RCA: 54] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2018] [Revised: 05/16/2018] [Accepted: 05/17/2018] [Indexed: 12/11/2022] Open
Abstract
Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease with a broad spectrum of liver injury. Oxidant stress is believed to be the pathogenesis of NAFLD as the "second hit". Hydrogen peroxide is widely used as an oxidant reagent to induce the oxidant injury of cells and larval zebrafish. Recently, cichoric acid is being studied extensively for its obesity attenuating, hepatic steatosis reduction and anti-oxidant effects. In this study, to identify whether CRA could protect the H2O2 induced oxidant injury via anti-oxidant impact by using L02 and HepG2 hepatocytes as in vitro and larval zebrafish as in vivo injury models, and evaluated the protective and anti-oxidant effects of CRA by pretreated it on both in vitro and in vivo models. CRA was found to reduce the production of ROS and MDA, activate the anti-oxidant enzymes SOD and GSH-px, and pathways Keap1-Nrf2 and HO-1. These results demonstrated that CRA might protect the liver injury by its anti-oxidant effect, which could be a potential therapeutic agent of NAFLD.
