Corrective impact of dihydroquercetin on oxidative metabolism in patients with type 2 diabetes mellitus living in the north

Objective. The aim of the paper is to analyze the impact of plant antioxidant "Dihydroquercetin Baikalsky" on the LPO-AOS system and carbohydrate-lipid metabolism in residents of Khanty-Mansiysk with type 2 diabetes mellitus. Materials and Methods. The study enrolled 132 adult residents of Khanty-Mansiysk, including 78 people with type 2 diabetes mellitus and 54 healthy subjects. The authors examined the indicators of pro- and antioxidant activity in blood samples in all the trial subjects: products of lipid peroxidation (LPO), the state of the antioxidant system (AOS), oxidative stress coefficient. Patients with type 2 diabetes mellitus (n=48) undergoing standard glucose-lowering therapy were taking 1 capsule (60 mg) of Dihydroquercetin Baikalsky post cibum daily. Statistica 10.0 and Microsoft Excel software package were used to process the results obtained. Results. It was found that 12-week dihydroquercetin intake led to a significant decrease in primary and secondary lipid peroxidation products and an increase of AOS activity, which indicated the antioxidant effect of the bioflavonoid. The authors noted a positive trend towards a decrease in the parameters of the carbohydrate-lipid profile. Conclusion. The data obtained indicate the antioxidant properties of dihydroquercetin in persons with type 2 diabetes mellitus.
