Food-induced cortisol secretion is comparable in lean and obese male subjects

Patricia Arroyo Tardio, Gabriela Baldini, and Eleonora Seelig

Introduction The hypothalamopituitary–adrenal (HPA) axis tightly regulates cortisol secretion ( 1 ). Cortisol is secreted in a circadian rhythm with a brisk increase upon awakening and a nadir around midnight ( 1 ). Food is an external factor

Open access

Circadian rhythm of salivary cortisol, plasma cortisol, and plasma ACTH in end-stage renal disease

Hershel Raff and Hariprasad Trivedi

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

Open access

Higher urinary cortisol levels associate with increased cardiovascular risk

Andrea V Haas, Paul N Hopkins, Nancy J Brown, Luminita H Pojoga, Jonathan S Williams, Gail K Adler, and Gordon H Williams

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

Association between posttest dexamethasone and cortisol concentrations in the 1 mg overnight dexamethasone suppression test

Bjørn O Åsvold, Valdemar Grill, Ketil Thorstensen, and Marit R Bjørgaas

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

Ghrelin stimulation by hypothalamic–pituitary–adrenal axis activation depends on increasing cortisol levels

I Azzam, S Gilad, R Limor, N Stern, and Y Greenman

, 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

Interleukin-2 drives cortisol secretion in an age-, dose-, and body composition-dependent way

Ferdinand Roelfsema, Peter Y Liu, Rebecca Yang, Paul Takahashi, and Johannes D Veldhuis

that it may be useful as an immuno-neuroendocrine probe of adrenal function ( 5 ). Nonetheless, virtually all studies were uncontrolled and performed in patients with advanced cancer, in whom cortisol responses differ from those of healthy men ( 5 ). In

Impact of age, sex and body mass index on cortisol secretion in 143 healthy adults

Ferdinand Roelfsema, Diana van Heemst, Ali Iranmanesh, Paul Takahashi, Rebecca Yang, and Johannes D Veldhuis

inferences. Nonetheless, multivariate analysis also is unreliable in small cohorts ( 19 , 20 ). In addition, given the large concentration difference across the 24-h cycle and the marked pulsatility of cortisol, studies using a single sample, or a few blood

Midnight salivary cortisol secretion associated with high systolic blood pressure in type 1 diabetes

Eva Olga Melin, Magnus Hillman, and Mona Landin-Olsson

with T1D was 35%, almost twice as high as in the non-diabetic population ( 2 ). Several factors might contribute to the development of hypertension, such as increased cortisol secretion ( 4 , 5 , 6 , 7 , 8 , 9 ), obesity ( 8 , 9 ), physical

Effects of mitotane treatment on human steroid metabolism: implications for patient management

L Ghataore, I Chakraborti, S J Aylwin, K-M Schulte, D Dworakowska, P Coskeran, and N F Taylor

patients treated with mitotane (9) . Patients with Cushing's syndrome receiving mitotane have shown decrease in the adrenal cortisol secretion rate over time but a faster clinical benefit, suggesting that cortisol bioavailability is also diminished (10

Validation of a novel automated system, Fluispotter®, for serial sampling of dried blood spots

Jesper Krogh, Peter Plomgaard, Ruth Frikke-Schmidt, Sten Velschow, Jesper Johannesen, Linda Maria Hilsted, Malene Schrøder, and Ulla Feldt-Rasmussen
