role of both overt and non-overt hypercortisolism in the pathogenesis of cardiovascular disease (CVD). However, much less is known about the CV effects of cortisol concentrations within the physiological range. While some studies have shown a link

Introduction The measurement of salivary cortisol has emerged as a first-line test in the evaluation of the hypothalamic–pituitary–adrenal (HPA) axis in humans and, in particular, for the diagnosis of endogenous hypercortisolism (Cushing

Introduction The 1 mg overnight dexamethasone suppression test (DST) is a common initial test for endogenous Cushing's syndrome (1) . The principle of the test is that dexamethasone will suppress ACTH and cortisol secretion in healthy individuals

, prolactin and cortisol ( 15 , 16 , 17 ). The stimulation of the HPA axis by ghrelin is exerted predominantly at the hypothalamic level ( 18 ) through vasopressin stimulation ( 19 ) and indirect activation of CRH neurons ( 20 , 21 ). Direct effects of

cortisol leads to Cushing’s syndrome, which exhibits metabolic features similar to metabolic syndrome ( 2 ). Accordingly, previous cross-sectional studies suggest that circulating cortisol concentrations are associated with metabolic syndrome, its
