Background: Obesity is followed by insulin resistance (IR) and low grade inflammation. In patients with metabolic syndrome (MS) and clinicaly evident vascular complications homocystein values are higher. Hyperhomocysteinemia correlates with hyperinsulinemia and IR, resulting in oxidative stress, which causes endothelial lesions and dysfunction, promoting atherosclerosis and hypertension.Objectives: To examine homocystein levels in patients with and witho...

It has been shown that low values of insulin sensitivity have been related to metabolic diseases. Exercise prescription is crucial to prevent low insulin sensitivity in general population, and athletes are good physiological model. If this assumption is correct, examine insulin sensitivity in elite athletes should reflect the positive effect of exercise on insulin sensitivity. The aim of this study was to investigate the effects of regular exercise on insulin sensitivity estim...

Abstract: Glomerular hyperfiltration has been suggested as a possible mechanism linking obesity and chronic kidney disease, independently of classical risk factors such as diabetes. In terms of determining the creatinine clearance has numerous drawbacks, in clinical use are predictors of glomerular filtration rate (GFR) which show varying degrees of accuracy in obese patients. The aim of our study was to determine whether it is in our group of obese patients without type 2 dia...

Introduction: The most common cause for persistent elevation of TSH levels in hypothyroid patients treated with levothyroxine is poor compliance. The levothyroxine absorption test (LAT) is usually confirmed this phenomenon called “pseudo-malabsorption”.Case report: Sixty-year-old female, weight 60 kg, BMI 24.3 kg/m2, presented with sleepiness, tiredness, fatigue and forgetfulness. Her skin was very dry and flaky. She had low toleranc...

Introduction: Multiple endocrine neoplasia syndrome type 1 (MEN1) associated thymic carcinoids (Th-NETs) are rare and have poor prognosis. Cushing syndrome (CS) caused by Th-NET in MEN1 syndrome is extremely rare.Case report: We report a case of a 55-year-old man with CS at presentation due to ectopic ACTH production in MEN1 syndrome. Thirty years ago, this patient had total gastric resection due to Zollinger-Ellison’s syndrome and extirpation of tw...

Balance between pro- and anti- inflammatory cytokines is necessary for the physiological functioning of the immune system. A chronic systemic inflammation is one of the causes of insulin resistance in obesity.The aim of this study was to investigate the pro-inflammatory cytokines and visfatin response to an single bout acute exercise in athletes and non-athletes, as well as the possible relationship pro-inflammatory cytokines with body composition and in...

Introduction: Women with polycystic ovary syndrome (PCOS) are at increased risk of developing insulin resistance (IR) and T2DM. In this study, we attempted to detect IR parameters that could be the best predictor T2DM in PCOS comparing to controls.Description of methods/design: In 130 women with PCOS (BMI=29.7±0.66 kg/m2; age: 25.6±0.59 years) and 41 controls (age and BMI matched) (BMI=28.5±1.35 kg/m2; age: 26.5±...

Pseudohypoparathyroidism type 1a (PHP1a) is disorder characterised by resistance to the biological actions of circulating parathyroid hormone (PTH) along with typical features of Albright’s hereditary osteodystrophy (AHO). Tissue-specific imprinting of GNAS gene results in complete resistance to PTH in renal proximale tubule, but skeletal responsiveness to PTH appears intact, since Gαs is biallelically expressed in human bones. The objective of this study was to dete...

The aim of this study was to investigate adipocytokine responses to an single bout acute exercise in elite athletes with a low percentage of body fat, elite athletes with a high percentage of body fat and sedentary controls. Sixteen athletes with low percentage of body fat (volleyball players, low fat athletes group, LFAG), 15 athletes with high percentage of body fat (the elite water polo players, high fat athletes group, HFAG) and 15 sedentary subjects participated in this s...

Introduction: Glucocorticoids (GCs) are the treatment of choice for moderate-to-severe and active Graves’ orbitopathy (GO), but optimal treatment is still undefined as serious side effects are great concern of GC therapy. The aim of the present study was to evaluate tolerability and safety of two different treatment protocols.Methods: Consecutive patients were divided according to the protocol of GC therapy into two groups: combined intravenous and ...
