Objectives: Insulin resistance and hyperinsulinaemia are implicated in the pathogenesis of the polycystic ovary syndrome (PCOS) in the majority of the cases. Adiponectin is adipose tissue-specific protein and its correlation with insulin resistance is well established. The aim of the study was to access the correlation between adiponectin and anthropometric and metabolic parameters in a group of women with PCOS.Methods: Thirty-one women with PCOS (age: 2...

Mutation Y791F of RET protooncogene is a well known mutation so far described in families with FMTC and familial pheochromocytoma in one family. It activates the receptor in a monomeric form. Here we present eight unrelated families with the same mutation but different fenotype expression.Patients and methods: In last 20 years, we analyzed 216 patients with MTC (age range: 3–75 years, 45.0 mean). Genetic testing for mutation in RET pro...

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder. The metabolic aspect of disorder is characterized by obesity-related risk factors for cardiovascular disease. The aim of this study was to determine in women with PCOS, indices of lipid metabolism and their oxidation, and to assess possible relation to insulin resistance. We investigated 75 women with PCOS (age: 23.1±5.1 years, body mass index (BMI): 24.9±4.7 kg/m2) and 56 age an...

We describe a 52-year-old woman, with acromegaly, clival chondroid chordoma, meningioma and lung carcinoid. There was no family history of MEN-1. She was diagnosed as acromegaly in 2000. Radiological evaluation (MRI) revealed pituitary tumor, however, another infiltration of scull base was detected which invaded sphenoidal and ethmoidal sinuses, lamina cribroza and bilateral orbit walls. Pituitary tumor was completely removed and the reduction of extra-sellar mass was performe...

The diagnosis of adult growth hormone deficiency (GHD) in patients with pituitary disease relies predominantly on provocative tests of GH secretion. The incidence of GHD in treated acromegalic patients has not been fully documented. Therefore, the aim of the present study was to elucidate GH response to insulin-induced hypoglycaemia (ITT, 0.15 IU/kg i.v.) in a cohort of 10 patients with acromegly considered cured solely by transsphenoidal surgery (6 females and 4 males, mean a...

Context: The early activation of adrenal zona reticularis, denoted by increased circulating levels of adrenal androgens before the age of eight years in girls is called premature adrenarche (PA), while the concomitant appearance of pubic hair is termed premature pubarche (PP). Girls with PA-PP display an unfavorable metabolic, hormonal and psychologic profile, compared to their normal peers and are also at an increased risk of developing polycystic ovary syndrome (PCO...

ObjectiveThe exact risk of type 2 diabetes in women with polycystic ovary syndrome (PCOS) is unknown. It is also unclear if obesity independently increases the risk in this population. The aim of this study was to systematically review and synthesize the best available evidence regarding the association between PCOS and type 2 diabetes, stratified according to obesity status.MethodsA comprehensive search was ...

Introduction: The association between CRP and prediabetes has not been sufficiently investigated. The aim of the study was to determine the association of prediabetes with subclinical inflammation, as well as to examine the correlation of sensitive CRP (hsCRP) with fasting glycemia and 2 h glycemia during exercise during the OGTT test.Methods: The study included 106 patients with angiographically diagnosed coronary artery disease, who, based on the oral ...

Introduction: Secondary failure (SF) of oral therapy in patients with type 2 diabetes is a common clinical phenomenon, which often puts the practitioner in a dilemma as to which therapeutic regimen to choose for continuing therapy. The dilemma primarily applies to patients in whom there is no clear clinical and biochemical evidence of significant insulin deficiency. This is precisely why there has been an increased interest in the use of short-term intermittent insulin therapy...

Single nucleotide polymorphisms in the glucocorticoid receptor (GR) gene influence tissue sensitivity of GR. Several studies have shown different effects of BclI GR polymorphism on body composition and metabolic parameters. The objective of this study was to explore the effect of BclI GR polymorphism on the body composition and glucose metabolism. Biochemical tests and hormonal evaluation were performed in 106 consecutive women with adrenal incidentalomas (AI...
