    Streszczenie angielskie: Intercellular adhesion molecule-1 (ICAM-1) is 1 of the possible factors linking obesity and diabetes with cardiovascular disease, however, the mechanism of the increase in ICAM-1 concentration in obesity remains unclear. Therefore, the aim of the present study was to assess plasma soluble ICAM-1 (sICAM-1) levels on obese subjects with normal glucose tolerance and to evaluate whether those levels may be related to insulin resistance and tumor necrosis factor-ŕ (TNFŕ) system activity. The study was performed in 8 lean and 15 obese subjects. Anthropometric and biochemical parameters were measured, and insulin sensitivity was evaluated using the euglycemic hyperinsulinemic clamp technique (insulin infusion, 50 mU x kg**-1 x h**-1). Obese subjects were markedly more hyperinsulinemic and insulin resistant and had higher plasma soluble TNF receptor 2 (sTNFR2) and sICAM-1 levels. sICAM-1 was related positively to body mass index (BMI), waist-to-hip ratio (WHR), percent of body fat, glycated hemoglobin (HbA1c), plasma insulin and triglycerides (TG), TNFŕ, and sTNFR2 and negatively to insulin sensitivity. Multiple regression analysis showed that only sTNFR2 and insulin sensitivity were independent predictors of sICAM-1 concentrations and were responsible for 66 p.c. of sICAM-1 variability. We conclude that an increase in plasma sICAM-1 concentration in obesity is related to TNFŕ system activation and insulin resistance.

    Streszczenie angielskie: It is hypothesized that adhesion molecules could be an early predictor of coronary artery diseases. Therefore we investigated the relationship between the concentrations of soluble forms of adhesion molecules and disturbances of glucose metabololism in 78 men referred for coronary angiography but with no previous history of diabetes. The group consisted of 78 men (mean age, 47.6 ń 7.0 years; mean body mass index [BMI], 28.4 ń 3.24 with the symptoms of angina pectoris and positive exercise test. All subjects were given a standard oral glucose tolerance test (OGTT) with glucose and insulin estimations. Fasting plasma concentrations of the soluble (s) forms of E-selectin, intercelular adhesion cell molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), and HbA1c were also measured. According to the OGTT, 10.2 p.c. of the patients (n = 8) fulfilled the criteria for type 2 diabetes mellitus and 44.9 p.c. (n = 35) for impaired glucose tolerance (IGT). The highest concentrations of sE-selectin were observed in patients with type 2 diabetes mellitus and were significantly higher in comparison to the group with normal glucose tolerance and IGT. The concentration of sVCAM-1 increased with the progression of disturbances of glucose metabolism and remained the highest in type 2 diabetic patients. sICAM-1 concentration was not significantly different. sE-selectin concentration correlated significantly with fasting glucose (r = 0.23, P = .041), postload glucose (r = 0.39, P = .001), and postload...

    Streszczenie angielskie: Obesity is associated with the increased risk of cardiovascular disease; however, mechanisms responsible for such an increase are not fully understood. IL-8 is a cytokine that might have atherogenic properties. Recent in vitro studies revealed that IL-8 is produced and secreted by human adipocytes. The aim of the present study was to evaluate plasma IL-8 concentrations in obese subjects and the realationships between circulating IL-8 and anthropometric and biochemical parameters and TNF-ŕ system. A total of 75 subjects with normal glucose tolerance, 35 lean and 40 obese, were recruited for this study. Plasma IL-8 levels were measured in fasting state, after an oral glucose tolerance test and after the euglycemic hyperinsulinemic clamp. A significant increase in plasma IL-8 was observed in the obese group. In simple regression analysis, performed for the initial evaluation of relationships, plasma IL-8 was related to body mass index, percentage of boody fat, fat mass (FM), and soluble TNF-ŕ receptor 2(sTNFR2) in the obese. In multiple regression analysis, FM, waist-to-hip ratio, gender, sTNFR2, and low density lipoprotein cholesterol were responsible for 44 p.c. of IL-8 variability. During oral glucose tolerance testing, mean plasma Il-8 concentrations increased in booth groups, whereas clamp resulted in a significant increase in plasma Il-8 only in the obese. We conclude that plasma IL-8 levels are increased in obese subjects, and are related to FM and TNF-ŕ system. Increase in circulating IL-8 might be one of the factors linking obesity with greater cardiovascular risk.

    Streszczenie angielskie: Insulin resitance is the main pathogenic factor of type 2 diabetes mellitus, and is also correlated with increased cardiovascular risk. Usually obese subjects show impaired insulin action. There are some factors secreted by the adipocytes which might be responsible for the development of insulin resistance. These are free fatty acids, leptin tumor necrosis factor-ŕ, interleukin 6 and the recently discovered resistin. In the present paper we describe the proposed role of these substances in the decrease of insulin action. It is suggested that future studies should be aimed at the decrease of insulin resistance by neutralisation of its mediators.
