Context: Irisin, a newly discovered hormone, is secreted by skeletal muscles into circulation. It is proposed to regulate energy homeostasis and hold therapeutic potential in diabetes and obesity.Objective: We aimed to investigate the association of irisin and uncoupling protein 1 (UCP1) with gestational diabetes mellitus (GDM).Design and Setting: This was a cross-sectional study conducted in a university hospital.<p class="abs...

Introduction: Apelin is an adipokine which plays a role in the regulation of glucose homeostasis. The relationship between apelin serum concentration and dysmetabolic conditions such as type 2 diabetes (T2D) is still controversial. The aim of our study was to investigate the association of apelin with gestational diabetes mellitus (GDM).Design and methods: This study was designed as a cross-sectional research that consecutively recruited subjects with GD...

Background: We investigated the demographic and clinical features of patients with Hashimoto’s thyroiditis who had been diagnosed and treated in Ege University, the main referral center in the Aegean region of Turkey.Methods: Medical records of patients who had been followed in the endocrinology clinic of Ege University were retrospectively evaluated. Patients who had been diagnosed as having any thyroid disorder were determined. Patients with Hashi...

Objective: Acromegaly is associated with increased cardiovascular mortality. Hyperhomocysteinemia has been associated with cardiovascular disease, lower-extremity peripheral arterial disease and heart failure. Data on the prevalence of hyperhomocysteinemia and peripheral arterial disease in patients with acromegaly is still limited. The aim of this study was to compare serum homocysteine levels between acromegaly patients with active disease and remission, and to evaluate pres...

Introduction and aims: Polycystic ovary syndrome (PCOS) is a frequent endocrinopathy among with young women. It is known that insulin resistance is encountered in the vast majority of the women with PCOS and hence the risk of type 2 diabetes mellitus and coronary artery disease are increased. These cardiac and metabolic risk increments may also associated with hyperandrogenemia and dyslipidemia. The metabolic changes of lipid profiles in young women with PCOS are not completel...

Pseudoacromegaly is a rare disorder characterized by cutaneous manifestations of growth hormone excess but with normal growth hormone levels or IGF-1. This condition described in patients with insulin resistance, hypothyroidism, pachydermoperiostitis and drug intake such as minoxidil. The hyperinsulinaemia impaired metabolic signalling may activate intact mitogenic signalling pathways and stimulate pathological tissue growth.A 41-year-old man presented w...

Context: Irisin is secreted by skeletal muscles into circulation and proposed to regulate energy homeostasis and hold therapeutic potential in diabetes and obesity.Objective: The aim of this study was to evaluate the effects of acute exercise training (6 week) on circulating plasma irisin in adult mens.Design and setting: This was a cross-sectional study conducted in a university hospital.Participants: A tota...

Introduction: We aimed to investigate the homeostasis model assessment of insulin resistance (HOMA-IR) and relation of HOMA-IR with age, sex and body mass index (BMI) and the prevalence of diabetes in Turkish population of different regions.Methods: Cross-sectional observational study was done in the frame of Turkish prevalence of insulin resistance multicenter study. The study sample consisted of volunteers from seven different regions of Turkey. Weight...

Introduction: Inferior petrosal sinus sampling for ACTH is the current gold standard test for the differentiation of pituitary Cushing disease from the ectopic ACTH syndrome. Early studies with İPSS reported a diagnostic sensitive and specificity approaching 100%, additional experience has shown a false negative rate of 1-10%. This has been due to either technical problem with unsuccessful petrosal sinus catheterization or anomalous venous drainage of the pituitary. The ...

Introduction: The aim of this study, left ventricular systolic and diastolic function by echocardiography and tissue Doppler echocardiographic evaluation and relationship serum N-terminal pro-B-type brain natriuretic peptide (NT-proBNP) levels of women with polycystic ovary syndrome (PCOS).Materials and method: Thirty-two women with PCOS (age: 23.4–4.6 years; BMI: 23.8–4.8 kg/m2), similar age and BMI have features 30 healthy womens c...
