The fast pace of life, promoting fast food consumption and low physical activity, has resulted in obesity and/or diabetes as being serious social problems.
The aim of the present study was to evaluate concentrations of selected adipokines (leptin, adiponectin, resistin, and visfatin) and to assess the leptin/adiponectin ratio in plasma of type 2 diabetes (T2D) patients in relation to degree of obesity.
MATERIAL AND METHODS: The study comprised 92 T2D subjects divided into 4 groups according to BMI value – I (normal body weight), II (overweight), III (obesity), and IV (severe obesity) – and 20 healthy volunteers (control group). Each group was divided into male and female subgroups. Plasma concentrations of adipokines were determined by enzyme-linked immunosorbent assay.
RESULTS: In women, leptin concentration was significantly higher in group IV, whereas in men it was higher in groups III and IV than in the control group and groups I and II. Irrespective of sex, a significant decrease in adiponectin level was observed in group III vs. control. There was no significant difference in resistin levels. In women visfatin was markedly enhanced in group III, whereas in men in groups II, III and IV vs. control. Leptin/adiponectin ratio was increased in groups III and IV vs. control in women, whereas in men vs. both control and group I.
CONCLUSIONS: The obese type 2 diabetic patients presented a disturbed adipokine profile, which seems to be an important link between obesity and T2D. The future studies concerning the question if regulating of adipokines’ concentrations could be a promising approach for managing metabolic disorders seem to be well-grounded.
