Introduction and aim: Obesity epidemic contributes to the increasing prevalence of high blood sugar, high blood pressure, and dyslipidemia, which are all known risk factors for coronary artery disease (CAD). Metabolic syndrome (MS) describes the common clinical finding wherein component CAD risk factors cluster within a single patient. Since obesity shares common clinical characteristics with both metabolic syndrome (MS) and Cushing’s syndrome it is speculated about obeso...

Somatostatinomas are rare neuroendocrine tumors of the pancreas and small intestine that can occur sporadically or in a syndromic form. Duodenal somatostatinomas are often associated with neurofibromatosis type1 (NF1). Their presenting features are mostly related to local effects of the tumor mass rather than functional clinical syndrome. Nesidioblastosis is extremely rare cause of persistant hyperinsulinemic hypoglycaemia in adults.We present a case of ...

A 25-year-old female, referred because of left hemianopsy, weight gain, fatigue, muscle weakness, and secondary amenorrhea. Physical examination revealed overt Cushingoid features and left temporal hemianopsy. Previously the diagnosis of pituitary macroadenoma (MRI) with suprasellar, infrasellar, and right parasellar propagation was made in regional hospital. Laboratory results showed moderate hypercalcemia with hypophosphatemia and hypercalciuria with inappropriately normal P...

Objectives: Besides well known increased adrenal androgen production, an enhanced peripheral cortisol metabolism was also observed in polycystic ovary syndrome (PCOS). This could induce a compensatory rise of ACTH secretion, tending to maintain normal plasma cortisol concentration at the expense of adrenal androgen excess. On the other hand, obesity is associated with a hyperactivity of the hypothalamic–pituitary–adrenal (HPA) axis and impaired androgen balance. In t...

Objectives: It is well known that polycystic ovary syndrome (PCOS) can promote metabolic syndrome (MetSy) and consequently cardiovascular diseases (CVD). In this study we compared indices of MetSy and 10-year cardiovascular risk (CVR10) based on Framingham risk scoring system (FRSS) in young obese PCOS women and healthy obese controls.Methods: We studied 25 obese women with PCOS (mean age: 29.55±4.6 years, mean BMI: 31.8±4.4 kg/m<sup...

Background: Narcolepsy is hypersomnia of central origin whose clinical features are excessive daytime sleepiness, hypnagogic hallutinations, sleep paralysis and cataplexy which comprises sudden transient loss of muscle tone often triggered by emotions. Narcolepsy with cataplexy is assiociated with hypocretin 1/orexin-A (HCRT 1/ORX-A) deficiency in central nervous system. Because of the link between ghrelin and HCRT 1/ORX-A wake-promoting effects there might be ghrelin deficien...

Introduction: Anorexia nervosa (AN) is a chronic disorder characterized of profound reduction in body weight and amenorrhoea. A product of complex interactions between psychological and clinical variables are important for the presence of the disease.Aim: The aim of the study was to investigate the variables which might predict full reproductive recovery of patients with anorexia nervosa.Material and methods: We studied closely mat...

Introduction: Both GH deficiency (GHD) and male hypogonadism are thought to be associated with an increased cardiovascular morbidity and mortality which is at least partly attributed to higher Insulin resistance. Potential reversibility of increased risk factors after gonadal replacement was assessed in this study, by comparing replaced and unreplaced hypogonadal men with GHD.Subjects and methods: Seventy-seven hypogonadal adult male patients with GHD ha...

The inflammatory response in rat models of obesity and malnutrition was examined. Rats received standard chow (control), chow enriched with 30% lard (obese) or 70, 50, 40 and 40% of expected food intake weekly for 4 weeks (starved). The serum levels of cytokines were determined by ELISA, while the expression of cytokine mRNA in heart and liver was analyzed by real-time RT-PCR. The blood concentrations of pro-inflammatory cytokines (TNF, IL-1) and Th1 cytokine IFN-gamma were si...

The aim of the study was to investigate the influence of intracerebroventricular (ICV) injections of ghrelin on secretion of pro-inflammatory (TNF, IL-1, IFN-γ) and anti-inflammatory cytokines (TGF-β) in starved rats. Male Wistar rats (4 weeks old, 12 per group) were fed ad libitum or starved by caloric restriction (40% of chow consumed by their ad libitum fed controls from previous day) for 4 weeks. Afterwards, half of the animals in each group receive...
