Abstract:
Summary. It was found that the comorbid course of nonalcoholic steatohepatitis and diabetic kidney disease in patients with type 2 diabetes mellitus is accompanied by a significant increase in the intensity of oxidative stress, accompanied by an increase in blood intermediate and final products of lipid peroxidation, lipid and oxidation. 3 times (p <0.05). The damaging effect of oxidative stress in patients with type 2 diabetes mellitus leads to the activation of apoptosis of hepatocytes with an increase in blood cytokeratin-18 (7.5 times, p <0.05), the content of which correlates with the degree of oxidative stress, the intensity of liver damage and stage of diabetic kidney disease (p <0.05). Oxidative stress increases the risk of endothelial damage by atherosclerotic process due to hyperproduction of homocysteine (3.9 times, p <0.05), which contributes to the progression of diabetic kidney disease. The use of quercetin in the complex therapy of non-alcoholic steatohepatitis and type 2 diabetes mellitus with diabetic kidney disease contributes to the probable reduction of oxidative stress, increased activity of antioxidant defense factors (content of reduced glutathione in erythrocytes, reduction of cytokeratin-18 content by 1.7 times) and endothelial damage (reduction of homocysteine content in blood by 1.9 times) (p <0.05). The comorbid course of nonalcoholic steatohepatitis and diabetic kidney disease in patients with type 2 diabetes mellitus is accompanied by a significant increase in the intensity of oxidative stress, accompanied by an increase in the content of intermediate and final products of lipid peroxidation and oxidative modification (p <0.05).
