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: Adipocyte fatty acid binding protein (A-FABP) is mainly expressed in adipocytes, and circulating A-FABP has been associated with markers of obesity. Women with PCOS are at increased risk of developing abdominal obesity what could be related to serum concentration of A-FABP.Aim: The aim of the present study was to investigate the relationships between serum concentration of A-FABP and parameters of obesity e.g. waist to hip ratio (WHR) and t...

Introduction: Polycystic ovary syndrome (PCOS) is associated with an increased risk of abdominal obesity, what is regulated by numerous genetic, epigenetic, and environmental factors. MicroRNAs (miRNAs) are known regulators of gene expression, involved in the development of metabolic disturbances. Dual-energy X-ray absorptiometry (DXA) is an accurate method of body composition analysis. The aim of the present study was to investigate the association between circulating miRNAs,...

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...

Polycystic ovary syndrome (PCOS) and type 1 diabetes (T1DM) are accompanied by increased risk of atherosclerosis. A higher prevalence of PCOS in T1DM patients has been reported. Brachial artery flow-mediated dilatation (FMD) and intima media thickness of common carotid artery (IMT) are used to detect an early endothelial dysfunction.The aim of our study was to examine IMT and FMD in T1DM women with PCOS. We also estimated the relation of IMT and FMD to c...

Introduction: The prevalence of polycystic ovary syndrome (PCOS) is increased in women with type 1 diabetes (T1DM) in comparison to the general population. It has been suggested that exogenous insulin administered to T1DM women in supraphysiological doses could act as co-gonadotropin and lead to disturbances observed in PCOS.Aim: The aim of this study was to evaluate the phenotypic characteristic and differences between diabetic women with PCOS (T1DM+PCO...

Introduction: Brain derived neurotrophic factor (BDNF) is a neurotrophin which plays a role in neuronal growth and differentiation. Decreased level of BDNF is supposed to play a role in the pathogenesis of the neurodegenerative diseases. Recent data indicate that BDNF could be also involved in angiogenesis. Several lines of evidence support the role of BDNF in glucose metabolism. The decreased level of BDNF are observed in obesity and type 2 diabetes mellitus. Polycystic ovary...

Introduction: The transcription factor 7-like 2 gene (TCF7L2) has the strongest effect on the risk of type 2 diabetes but the mechanism for this is not fully understood. Some genetic variants are associated with pancreatic B-cell function and some single nucleotide polymorphisms show a significant correlation with obesity. The aim of the study was to analyze whether TCF7L2 variants may influence body weight and body fat content, as well as postprandial glucose metabolism in no...

Introduction: Polycystic ovary syndrome (PCOS) and type 1 diabetes (T1DM) are accompanied by an increased risk of cardiovascular complications. The higher prevalence of PCOS in T1DM was reported and thus T1DM women with PCOS exhibit a higher risk of cardiovascular diseases. Soluble E-selectin (sE-selectin) and intercellular adhesion cell molecule-1 (sICAM-1) are considered as an early markers of atherosclerosis.Aim: We aimed to evaluate plasma levels of ...

Introduction: Polycystic ovary syndrome (PCOS) is associated with an increased risk of insulin resistance. The involvement of microRNAs, small, non-coding molecules, in regulation of metabolic processes has been investigated. The role of miR-27a and miR-320 in regulation of glucose metabolism is documented. The aim of the study was to assess the level of circulating miR-27a and miR-320 in PCOS patients and to investigate its relationship with glucose metabolism.<p class="a...
