Before the introduction of mandatory salt iodination in 1997 the North-Eastern Region of Poland was known to be a moderate iodine deficiency area. It was also exposed to ionizing radiation after the Chernobyl accident in 1986. The aim of the present study was to evaluate the descriptive epidemiological features of incident thyroid cancers diagnosed among the residents of this area between 1996 and 2007. The Regional Cancer Surveillance Program was used to collect data on 834 n...

Visfatin, a protein secreted by the adipose tissue, might regulate insulin action. The aim of the present study was to assess serum visfatin concentration in obese women with normal glucose tolerance (NGT) and impaired glucose tolerance (IGT) and to estimate the relationships between serum visfatin concentration and insulin sensitivity, blood pressure, proinflammatory and proatherogenic factors.The study group consisted of 134 women: 30 overweight or obe...

One of the key actions of insulin is the regulation of glucose and lipid oxidation. Disturbances in substrate oxidation play an important role in the development of insulin resistance. Insulin action is inversely associated with circulating pro-inflammatory cytokines such as soluble TNF-α receptors (sTNFR1 and sTNFR2).The aim of the present study was to analyze the associations between serum sTNFR1 and sTNFR2 concentrations and glucose and lipid oxi...

Polycystic ovary syndrome (PCOS) is heterogeneous disorder, where insulin resistance might be involved in the development of endocrine and metabolic abnormalities. Insulin resistance is associated with the so-called metabolic inflexibility i.e. an impaired switch from lipid to glucose in response to insulin. The aim of the present study was to estimate glucose and lipid oxidation, metabolic flexibility and non-oxidative glucose metabolism in lean and obese PCOS patients.<p...

Anorexia nervosa (AN) is an eating disorder, with the significant loss of the adipose tissue. Lack of subcutaneous adipose tissue observed in lipodystrophies is accompanied by insulin resistance. The crucial step in the development of insulin resistance is an impaired increase in carbohydrate oxidation and decrease in lipid oxidation in response to insulin. The aim of the present study was to estimate carbohydrate and lipid oxidation in relation to serum adiponectin concentrat...

Markers of endothelial dysfunction, including soluble E-selectin (sE-selectin) are related to insulin resistance and are predictors of type 2 diabetes. Insulin resistance is associated with metabolic inflexibility, i.e. an impaired stimulation of carbohydrate oxidation and inhibition of lipid oxidation in insulin-stimulated conditions. The aim of the present study was to estimate the relationships of serum sE-selectin concentration with carbohydrate and lipid oxidation in lean...

Gestational diabetes mellitus (GDM) identifies a population of women at high risk of subsequent type 2 diabetes mellitus, representing an early stage in the natural history of the disease. Systemic inflammation is associated with the development of type 2 diabetes but the data concerning pro- and anti-inflammatory cytokines in patients with GDM are limited. The aim of our study was to investigate serum concentrations of interleukin-8 (IL-8), IL-18 and IL-10 in pregnant women w...

Background: Obesity is associated with an increased risk of impaired glucose tolerance and type 2 diabetes. Insulin resistance is the link between obesity and disturbances of glucose metabolism. It is suggested that some substances secreted by adipose tissue might play a role in the pathogenesis of insulin resistance. One of these substances is interleukin-6 (IL-6), cytokine, which regulates synthesis of the acute-phase proteins in the liver. The aim of the present study was t...

Aim of the study: Polycystic ovary syndrome (PCOS) is common disease affecting women in reproductive age which leads to anovulation. In pathogenesis of PCOS insulin resistance plays an important role. The aim of the present study was to look for possible relationship between interleukin 18 (IL-18) and insulin resistance in patients with PCOS.Material and Methods: The study was done in 76 patients with PCOS and 40 women without menstrual disturbances. The...

Introduction: Type B insulin resistance syndrome is an autoimmune disorder characterized by the production of autoantibodies against the insulin receptor. It leads to glucose metabolism disorders, extreme insulin resistance, hyperandrogenism and is associated with other features of autoimmunity.Case report: A 27-year-old man, with a 2-years history of psoriasis, was admitted to our Department because of loss of weight (20 kg in 1 year) and fatigue. He al...
