Mechanisms of formation and progression of non-alcoholic fatty liver disease in type 2 diabetics

Currently, study of the mechanisms of formation and progression of non-alcoholic fatty liver disease (NAFLD) in the patients with type 2 diabetes mellitus (DM) is a topical problem in endocrinology. Prognosis for the disease depends on NAFLD stage and it determines the necessity to study the origin and mostly the progression in NAFLD course. It will favour the enhancement of efficacy of the treatment for this cohort of patients. The object of this work was to study the mechanisms of formation of NAFLD phasic course in type 2 diabetics via determining the levels of lipid peroxidation (LPO), 8-isoprostaglandin as components of oxidative stress. LPO indices and liver functional activity parameters (general cholesterol, high-density lipoproteids cholesterol, triglycerides, β-lipoproteids, very-low-density lipoproteids cholesterol, atherogenicity coefficient, thymol test, alanine aminotransferase, aspartate aminotransferase) were determined in the examined individuals. The carried research allowed, that changes in biochemical parameters levels is connected with increasing of diene conjugates (DC) activity and the carried correlation analysis of the studied values proved this relevance. The subgroup of the patients with DC levels of 200-400 nmol/l has no inflammatory alterations (cytolysis syndrome) that gives evidence of steatosis phase. The group of patients with DC levels of 400-600 nmol/l demonstrated the stage of non-alcoholic steatohepatitis with the most expressed shifts in functional liver condition. The greatest lipid, carbohydrate metabolic changes were found in the subgroup of the patients with DC level of 600 nmol/l and more that gives evidence of fibrotic processes.
