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...

Aim: The aim of this study was to compare clinical symptoms and TSH receptor antibodies (TRAb) in Graves orbitopathy (GO) in hyperthyroid patients to those patients with primarily hypothyroid and euthyroid status.Methods: Study group consisted of 54 primarily hyperthyroid (39 female, 14 male, 47±9 years) and 8 primarily hypothyroid and euthyroid patients (5 female, 3 male, 46±14 years). Clinical symptoms and TRAb were assessed. Assessment of th...

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...

It was previously shown that patients with primary hyperparathyroidism (PHPT) are insulin resistant.Aim: The aim of our study was to evaluate the effect of surgical treatment on glucose tolerance, insulin secretion and sensitivity (SI) in patients with PHPT.Material and methods: In 26 patients with PHPT (age: 57.15±9.54 years, BMI 26.00±4.55 kg/m2, PTH 276.61±64.83 ng/l, Calcium 2.95±0.19 mmol/l)) AIR...

Objective: It was previously shown that primary hyperparathyroidism (PHPT) might induce impaired renal function and chronic renal failure. The aim of our study was to evaluate the effect of surgical treatment on parameters of calcium and phosphate renal metabolism and renal function in patients with PHPT.Material and methods: In 26 patients with PHPT (age: 57.15±9.54 years, BMI 26.00±4.55 kg/m2, PTH 276.61±64.83 ng/l, Calcium 2....

Objective: It was previously shown that patients with primary hyperparathyroidism (PHPT) have atherogenic dyslipidaemia. The aim of our study was to evaluate the effect of surgical treatment on lipid levels in patients with PHPT.Material and methods: In 26 patients with PHPT (age: 57.15±9.54 years, BMI 26.00±4.55 kg/m2, PTH 276.61±64.83 ng/l, Calcium 2.95±0.19 mmol/l) Total cholesterol (TC), HDL-C, LDL-C, triglyceride (TG),...

Introduction and aims: Recent epidemiological studies have suggested serum gamma glutamyltransferase (GGT) within its normal range might be an early marker of oxidative stress. Oxidative stress appears to be a key component of many reactions associated with chronic inflammation. Obesity is associated with elevated levels of biomarkers of inflammation and endothelial dysfunction. Oxidative stress and inflammation are also known to play critical roles in the pathogenesis of vasc...

Anorexia nervosa (AN) is a chronic disorder characterized of profound reduction in body weight and amenorrhoea. Despite emaciation and avoidance of cholesterol-rich food, hypercholesterolaemia is a common feature. The aim of the study was to investigate the changes in lipid metabolism with weight gain in 17 severe AN patients aged 23.8±1.6 years (DSM-IV criteria). They were compared with age-matched cohorts of 11 healthy controls (22.5±3.9 years) before and after wei...
