Abstract
BACKGROUND: The problem of metabolic syndrome is considered a demographic catastrophe. According to WHO experts,«by 2025, the prevalence of metabolic syndrome (MS) in the world will amount to more than 300 million people, and in the next 25 years it is expected to increase by 50%.» The pathophysiological mechanisms of MS formation and the role of unhealthy diet on the development of intestinal dysbiosis, mitochondrial insufficiency remain unclear.AIM: To study the effect of unhealthy diet on the state of the intestinal microbiota and the development of metabolicmitochondrial insufficiency in the formation of a multi-organ metabolic syndrome, evaluation of ways of correction.MATERIALS AND METHODS: Clinical picture assessment, anthropometric data (body mass index), laboratory results (glucose, cholesterol and fractions) were carried out in patients with MS, triglycerides, aspartate aminotransferase, alanine aminotransferase, C-reactive protein, lipid peroxidation indicators: malondialdehyde, diene conjugates, schiff bases, hydroperoxides, catalase, superoxide dismutase, succinate dehydrogenase (ASDH), α-glycerophosphate dehydrogenase (α-AGFDH). Hemorheological parameters were evaluated by the apparent viscosity of blood, the yield strength, the aggregation coefficient of erythrocytes and platelets. The microbiota and microbiome of the intestine were evaluated by species, strain composition and the level of metabolites-propionic, butyric, acetic acid, lipopolysaccharides, peptidoglycans. A questionnaire was conducted to study the nature of nutrition.RESULTS: The study included 128 patients with MS and 25 healthy individuals. According to medical outpatient records from anamnesis, questioning of each patient, complaints and clinical picture, 26.2% of patients had type 2 diabetes, 3.74% of men had erectile dysfunction, 7.5% of women had polycystic ovaries, 15.1% had night apnea syndrome, 8.7% hyperuricemic syndrome, 96.5% of patients had metabolic fatty liver steatosis. According to the results of the survey, it was revealed that 99.8% of patients adhered to an unhealthy and unbalanced, high-calorie diet, 46.4% of patients had a low level of physical activity, 48.7% had an average. The revealed disorders of lipid, carbohydrate metabolism, microbiota and intestinal microbiome were associated with increased lipid peroxidation, decreased levels of antioxidant defense enzymes, indicators reflecting mitochondrial function against the background of hemorheological disorders.CONCLUSION: In multi-organ MS, unhealthy diet can be considered as a targeted risk factor triggering pathophysiological mechanisms at the level of the intestinal microbiota, followed by a cascade of metabolic disorders in the form of activation of lipid peroxidation with inhibition of antioxidant defense enzymes, the development of multi-organ mitochondrial insufficiency and the development of latent hemorheological syndrome. The revealed metabolic complex obviously constitutes a multiorgan morphological cluster underlying the development of multi-organ metabolic syndrome. Based on the identified disorders, pathogenetically justified correction of MS should include a balanced diet with mitochondrial protective therapy.
