Introduction: Polycystic ovary syndrome (PCOS) is associated with higher risk of cardiovascular disease. Measurement of carotid intima-media thickness (CIMT) is a simple non-invasive procedure for assessment and measurement of atherosclerotic plaque. It is a valuable tool for evaluation of cardiovascular disease risk, as increase in CIMT is associated with cardiovascular events, mainly stroke. In this study we evaluated association and influence of metabolic disturbances on CI...

Introduction: Narcolepsy is a rare sleep disorder characterized by excessive daytime sleepiness and REM-sleep abnormalities. Lateral hypothalamic hypocretin/orexin neurones are critical for normal wakefulness and energy expenditure, and the reduction of their activity has been linked with narcolepsy. Their activity is inhibited by extracellular glucose and the ‘satiety’ hormone leptin but stimulated by the ’hunger’ hormone ghrelin. Patients with narcolepsy ...

Background: Several stimulatory tests for differential diagnosis of ACTH dependent Cushing’s syndrome are avilable, CRH being the most valuable test in patients with Cushing’s disease (CD). Exaggerated responses to ghrelin have also been shown in patients with CD mainly due to overexpression of GHS receptors on corticotrope tumor cells. However, the effects of combined stimulation with CRH+ghrelin on ACTH and cortisol secretion have not been tested before in these pa...

Anorexia nervosa (AN) is known as a state of gonadotrophin and leptin deficiency. Leptin, the product of OB gene, secreted by adipocytes, is proved to play an important role in regulating apetite and energy expenditure. Thyroid hormones are Important regulators of total energy expenditure are thyroid hormones and also are able to increase oxygen consumption by tissues. The aim of the study was to evaluate a possible interaction of thyroid hormones (T3, T4...

Introduction: Polycystic ovary syndrome (PCOS) is a frequent metabolic disorder in women of the reproductive age, and is characterized by multi-factorial cardiovascular risk factors. Insulin resistance is proposed as a central factor linking PCOS to increasing risk of cardiovascular disease. The aim of our study was to explore a link between insulin resistance and oxidative stress, as a predictor of cardiovascular risk, in young, non-obese PCOS women.Met...

Introduction: Posttraumatic stress disorder (PTSD) is anxious disorder that occurs following exposure to trauma. In the last two decades, numerous studies showed that dysregulation of hipothalamo–pituitary–adrenal axis (HPAA) is a core feature of the PTSD. Still, results are heterogeneous and often conflicted with one another. Therefore, we conducted strictly controlled study in order to characterize relationship between ACTH and cortisol secretion in patients with c...

Gaucher disease (GD) is autosomal recessive lysosomal storage disorder caused by the deficiency of glucocerebrosidase with consequent massive acumulation of lipid-laden macrophages in various tissues. Estimated life expectancy is about 9 years shorter than for the reference population. Mortality due to macrovascular diseases is higher, and probably associated with metabolic abnormalities found in GD type 1 patients, including decreases in serum adiponectin levels. Because adip...

The aim of this study was to compare metabolic profile in hypertensive obese and lean subjects. The study population consisted of 76 patients. We measured fasting glucose and insulin levels, triglycerides, total, LDL and HDL cholesterol. We also estimated the BMI, WHR, systolic (SBP) and diastolic blood pressure (DBP). We used WHO criteria for abdominal obesity (WHR>0.90 men, >0.85 women), and WHO criteria for diagnosing the metabolic syndrome (triglyceride>1.7 mmo...

The short-term results of transsphenoidal surgery as initial treatment for acromegaly were analyzed according to consensus defining the criteria for cure of acromegaly.Thirty nine newly diagnosed patients with acromegaly (20 females and 19 males, mean age 46.9 plus/minus 1.4 years, range 29-66 yrs), underwent transsphenoidal pituitary adenomectomy by the same neursurgeon. Patients have been assessed postoperatively at 8 weeks (GH after 75 g oral glucose ...

Introduction: Metabolic syndrome (MS) is an independent risk factor of coronary artery disease (CAD). We investigated how influenced this risk is by the definition of MS, and whether the risk is greater than that conferred by its components.Methods: We analyzed 200 consecutive patients (35–79 years, mean 59.23±8.6, men 132, women 68) who underwent coronary angiography due to suspected myocardial ischemia. MS was obtained by several definitions:...
