- Abstract
The purpose of the study was to reveal a possible role of adipokines, biologically active adipose tissue proteins (leptin and adiponectin) and nonesterified fatty acids in generating insulin resistance (IR). One hundred and fifty-seven patients (90 females and 67 males) aged 57.5±9.2 years were enrolled in the study. According to the HOMA index for IR, the patients were divided into 3 equal groups. The examinees with a high HOMA index were found to have elevated levels of fatty acids, leptin and decreased concentrations of adiponectin. At the same time according to the linear regression analysis, all these indices are its independent determinants. However, analysis of the data in the groups of patients with different body weight revealed that the increased concentrations of fatty acids and leptin may play a role in the development of IR in subjects with obesity while the higher level of fatty acids and lower adiponectin may be involved in patients without noticeable obesity. Thus, it may be assumed that leptin, adiponectin and nonesterified fatty acids may affect the development of IR; however, their contribution depends on the degree of adiposity.
