One of the urgent problems of Endocrinology is the study of the mechanisms of formation and progression of nonalcoholic fatty liver disease (NAFLD) in patients with diabetes mellitus (DM) type 2. Prognosis depends on the stage of NAFLD in which the changes occur and secretion of adipocytokines in the first place, adiponectin. The aim of the study was to: define adiponectin levels in the circulation of patients with type 2 diabetes at different stages of NAFLD and its impact on the detection of metabolic changes, the establishment of linkages with carbohydrate, lipid, protein metabolism, and liver function. The study determined the relevance of the study of pathogenetic mechanisms of NAFLD in the future, because the violation of metabolic control and reduce the protective properties of adipocytokines in patients with comorbid disorders is of great interest to further improve diagnostic capabilities, prevent complications and improve the quality of life of these patients.

Genetic analysis was carried out on the material including clinic and genealogical data about 510 patients with type 2 Diabetes Mellitus, 445 Essential Hypertension individuals, 239 abdominal obesity persons and their 1st degree relatives. It has been shown that the Essential Hypertension and abdominal obesity distribution in the population and families can be described by means of a variants polygene model with essential influence of the major genes. Gene complexes of predisposition to obesity, Essential Hypertension and Type 2 Diabetes Mellitus are independent, however, their liabilities are covered.

A study made in 77 patients with different form of thyropathy revealed increased blood plasma and erythrocyte content of lipid peroxidation products, such as diene conjugates and TBA-active producers. The plasma chemiluminescence got more intense as well. Different mechanisms for the lipid peroxidation activation in patients presenting with thyroid hormone abundance or deficiency have been analyzed.
