Introduction: Several studies have shown that cortisol and altered HPA axis activity may participate in pathogenesis and severity of coronary artery disease (CAD).Aim: To examine possible interaction between cortisol secretion and HPA axis activity with severity of CAD.Patients and methods: Diurnal cortisol secretion and dexamethasone suppression test (DST) were analyzed in 200 consecutive patients (mean age 59.3±8.6) referred...

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 ...

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: Rheumatoid arthritis (RA) is a chronic inflammatory disease which is characterized with dysregulation of the immune system. Recent studies suggest that dysregulation of the HPA axis may as well play a contributory role in the pathogenesis of RA. Glucocorticoid hormones (GC) accomplish their effects through binding to glucocorticoid receptor (GR). Presence of GR gene polymorphisms can modulate GC effects. The A3669G polymorphism in human GR gene has been connected...
