The accumulated data underline the role of betatrophin in glucose homeostasis. Polycystic ovary syndrome (PCOS) is characterized by insulin resistance and high risk of developing prediabetes and diabetes. The aim of our study was to investigate the relationship of serum betatrophin concentrations with indirect indices of insulin resistance and insulin secretion in women with PCOS, comparing to the control group. The study group comprised 43 women with PCOS and 16 controls matc...

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,...

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...

Purpose: Recent reports strongly suggest that at least some cases of Hashimoto’s thyroiditis (HT) may be closely associated with IgG4-related disease. In the present study we aimed to find out, whether the measurement of serum IgG4 allows for an identification of distinct types of HT, with different clinical, sonographic and serologic characteristics.Methods: The group studied consisted of 53 patients with HT and 28 healthy individuals. All the part...

Introduction: Thyroid hormones deficiency in the course of subclinical and overt hypothyroidism is frequently related to the increased body mass, reduced thermogenesis and metabolic rate however the pathogenesis of improper body mass in Hashimoto thyroiditis (HT) patients is still an open question. Therefore, in the present study we compared body mass and body composition between the patients with Hashimoto thyroiditis who were in clinical and hormonal euthyreosis and healthy ...

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...

Objective: Polycystic ovary syndrome (PCOS) is more prevalent among women with type 1 diabetes (T1DM) than in general population. Autoimmune thyroiditis (AIT) is the most common autoimmunological disease in young women in reproductive age, especially in T1DM. Data in literature indicate the possible role of thyroid autoimmunity in PCOS pathogenesis. It has been suggested that positive concentration of thyroid peroxidase antibodies (TPOAbs) is associated with increased prevalen...
