Introduction: Impaired insulin sensitivity accompanies polycystic ovary syndrome (PCOS). Women with PCOS are usually at risk of premature cardiovascular disease, which increases with age and body weight. We studied the link between insulin sensitivity measured by the Matsuda Insulin Sensitivity Index (MISI) adjusted to body mass index (BMI) and age in otherwise healthy PCOS women.Methods: 250 adult women with PCOS of reproductive age (18-43 years old) un...

Obesity is defined as a state of chronic low-grade inflammation. It is associated with pro-inflammatory activity of visceral adipose tissue, regarded as a neuroendocrine organ that secretes cytotoxins and other pro-inflammatory factors, impairing metabolic pathways. The corollary of these changes is the risk of developing comorbidities. There are many similarities in the mechanisms of ageing and in obesity. The process of ageing leads to the accumulation of pro-inflammatory fa...

Introduction: Due to the frequent occurrence of adrenal incidentalomas, diagnosis of their hormonal activity is a significant clinical concern. Approximately 7-10% of adrenal tumors are pheochromocytomas, which even in silent form can lead to hemodynamic instability during surgery. According to the ESE and ENSAT guidelines in any case of adrenal tumors greater than 1 cm pheochromocytoma should be excluded based on plasma metanephrines level and urinary metanephrines excretion....

Objective: Previous studies indicated that two glucocorticoid receptor gene polimorphisms bclI and N363S (GC-S) are associated with increased sensitivity to glucocorticoids and two other polymorphisms 9β and ER22/23EK (GC-I) are related to decreased sensitivity to glucocorticoids. The aim of the study was to determine whether these genetic changes can effect on the occurence of steroid-induced adverse events.Methods: One hundred and fifty p...

Introduction: Adult male offspring of women with PCOS have increased dyslipidaemia, characterised by elevated triglycerides (TG), increased total and LDL-cholesterol (LDL-C), and hyperinsulinaemia. As altered intrauterine endocrine environments can ‘programme’ adverse health outcomes in adulthood we hypothesised that this dyslipidaemia was a consequence of a hyperandrogenic intrauterine environment. We used an outbred large animal model to identify if prenatal androg...

Introduction: Altered intrauterine endocrine environments can ‘programme’ adverse health outcomes. Linkage between altered androgen exposure in utero and adverse offspring health is robust. For example, increased maternal androgen concentrations and PCOS in female offspring and dyslipidaemia in male offspring. We hypothesised that the liver was a major target for androgenic programming in utero and hepatic dysfunction would be present in offspring. ...

Isolated hypogonadotropic hypogonadism (IHH) is known to decrease bone mineral density due to lack of pubertal surge of gonadotropins and deficiency of sex steroid hormone. Gonadal steroid hormones imbalance affects body composition. Nineteen Caucasian men, 22–48 year old (mean±S.D. 33±7.65) diagnosed with IHH (8 normosmic, 11 anosmic or hyposmic) were enrolled into the study. 14 patients were on hormone replacement therapy (HRT), 5 patients were ...

Introduction: BCC is a congenital epithelial neck cyst, which occurs due to failure of the second branchial cleft to obliterate during embryogenesis. Development of PTC inside the cyst is extremely rare.Case description: A 29-year-old female presented to the endocrinology clinic with a gradually increasing painless mass in the right lateral region of the neck, identified on ultrasound examination as an anechoic cyst of size 2×2×5 cm with a smoo...

Aim: Clinical studies in Hashimoto thyroditis (HT) confirm, that even a minor thyroid dysfunction is related to significant changes in body mass. Betatrophin, also known as TD26/RIFL/lipasin/ANGPTL8/C19orf80, is a novel protein predominantly expressed in human liver and adipose tissue. Stimulators of betatrophin, such as thyroid hormones are usually relevant to energy expenditure or thermogenesis. The mechanisms of action of betatrophin are still unknown. In the present study ...

Introduction and aims: To date we have had some evidence that betatrophin is associated with insulin resistance. Some studies have demonstrated that betatrophin levels are elevated in type 2 diabetes, obesity and gestational diabetes. It has been shown that in mice betatrophin significantly improves beta cell function and glucose tolerance. This is the first study on betatrophin in which pregnant women were observed during all trimesters and in postpartum period to evaluate it...
