Introduction: Glycoprotein 130 (gp130) cytokines, like interleukin 6 (IL6), act through plasma membrane receptors consisting of two glycoproteins: a cytokine binding subunit (like IL6R) and gp130, responsible for signal transduction. IL6 may regulate insulin sensitivity in a dual manner, as both insulin-sensitizing and -desensitizing actions have been reported. Other gp130 cytokines may have a beneficial metabolic effects. The aim of the present study was to assess skeletal mu...

Introduction: Numerous studies indicate an association between low-grade chronic inflammation and predisposition to type 2 diabetes and atherosclerosis. IL18 is a proinflammatory cytokine with proatherogenic properties. Existing evidence indicated that circulating IL18 was associated with insulin resistance, metabolic syndrome and type 2 diabetes. Some data suggest that endogenous IL18 signaling modulates food intake, metabolism and adiposity, as homeostatic regulator. The aim...

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...

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: 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...

Visfatin is a newly discovered protein secreted by adipose tissue, which is suggested to play a role in pathogenesis of insulin resistance. Polycystic ovary syndrome (PCOS) is heterogeneous disorder, where insulin resistance might be involved in the development of endocrine and metabolic abnormalities. The aim of the present study was to asses the relation between serum visfatin and insulin sensitivity and markers of hyperandrogenism in a lean and obese PCOS patients. The stud...

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...

Introduction: Parathyroid carcinoma is a rare endocrine malignancy accounting for <1% of all cases of hyperparathyroidism. Diagnosis and treatment is still difficult.Case report: A 32-year-old women was admitted to the hospital because of mental status changes, polyuria, polydipsia, musculoskeletal pain and weight loss (34 kg during last year). She had history of nephrolithiasis, pancreatitis, cholelithiasis, peptic ulcer disease, osteoporosis and di...
