FAT AND MUSCLE COMPONENTS OF BODY WEIGHT AND THEIR RELATIONSHIP WITH THE CONCENTRATION OF SERUM ADIPOKINES IN PATIENTS WITH NONALCOHOLIC FATTY LIVER DISEASE

Abstract

The aim: Identify differences in indexes of body fat and muscle masses, as well as blood adipokines in patients with nonalcoholic fatty liver disease, from gender-appropriate healthy men and women. Materials and methods: 135 patients with non-alcoholic fatty liver disease with normal, overweight and obesity and 20 almost healthy individuals for the control group were examined. Verification of the diagnosis was performed in accordance with the recommendations of the unified clinical protocol. An anthropometric examination of patients was performed according to the method, which included the determination of 48 anthropometric parameters. The formulas determined the absolute amount of adipose and muscle tissue. Levels of adipokines (leptin and adiponectin) were determined by enzyme-linked immunosorbent assay. Results: According to Matiegka, body fat was 30.2-35.2% higher, and muscle body weight was 17.4-29.1% lower in patients with non-alcoholic fatty liver disease compared to healthy people. The concentration of leptin in the serum of patients with nonalcoholic fatty liver disease was statistically significantly higher (2.05-3.78 times) compared with almost healthy individuals. At the same time, the indicators of adiponectin concentration (1.54-1.92 times) and log A / L index (1.16-1.32 times) were lower. Correlations between changes in muscle mass and adipokines concentration have been established. Conclusions: In addition to the known increase in body fat in non-alcoholic fatty liver disease, there has been established a significant decrease in muscle mass. A direct correlation between adiponectin concentration and an inverse correlation between leptin levels and muscle mass in patients with nonalcoholic fatty liver disease was found.
