Journal ArticleDOI
Endocrine activities of ghrelin, a natural growth hormone secretagogue (GHS), in humans: comparison and interactions with hexarelin, a nonnatural peptidyl GHS, and GH-releasing hormone.
Emanuela Arvat,M. Maccario,L. Di Vito,Fabio Broglio,Andrea Benso,C. Gottero,M Papotti,Giampiero Muccioli,C. Dieguez,Felipe F. Casanueva,Romano Deghenghi,F. Camanni,Ezio Ghigo +12 more
TL;DR: Ghrelin, a natural ligand of GHS-receptor, exerts a strong stimulatory effect on GH secretion in humans, releasing more GH than GHRH and even more than a nonnatural GHS such as HEX, which possesses strong GH-releasing activity but also significantly stimulates PRL, ACTH, and cortisol secretion.
Journal ArticleDOI
Preliminary evidence that Ghrelin, the natural GH secretagogue (GHS)-receptor ligand, strongly stimulates GH secretion in humans.
Emanuela Arvat,L. Di Vito,Fabio Broglio,Mauro Papotti,Giampiero Muccioli,Carlos Dieguez,Felipe F. Casanueva,Romano Deghenghi,Franco Camanni,Ezio Ghigo +9 more
TL;DR: An endogenous ligand for the GH secretagogue-receptor (GHS-R) has been recently purified from rat and human stomach and named Ghrelin exerted a strong stimulatory effect on GH secretion in humans releasing more GH than GHRH.
Journal ArticleDOI
Retesting young adults with childhood-onset growth hormone (GH) deficiency with GH-releasing-hormone-plus-arginine test.
Gianluca Aimaretti,Claudia Baffoni,S. Bellone,L. Di Vito,G. Corneli,Emanuela Arvat,L. Benso,Franco Camanni,Ezio Ghigo +8 more
TL;DR: G HRH + arginine (GHRH+ARG) is the most reliable alternative to the insulin-induced hypoglycemia test (ITT) as a provocative test for the diagnosis of GHD in adulthood, provided that appropriate cut-off limits are assumed.
Journal ArticleDOI
Low dose (1 μg) ACTH test in the evaluation of adrenal dysfunction in pre-clinical Addison's disease
Stefano Laureti,Emanuela Arvat,Paola Candeloro,L. Di Vito,Ezio Ghigo,Fausto Santeusanio,Alberto Falorni +6 more
TL;DR: The clinical use of the low‐dose ACTH test (LDT) in the diagnosis of early adrenocortical dysfunction in patients with adrenal autoantibodies was evaluated.
Journal ArticleDOI
The GH, prolactin, ACTH and cortisol responses to Hexarelin, a synthetic hexapeptide, undergo different age-related variations
Emanuela Arvat,J. Ramunni,J. Bellone,L. Di Vito,Claudia Baffoni,Fabio Broglio,Romano Deghenghi,E. Bartolotta,Ezio Ghigo +8 more
TL;DR: It is demonstrated that in humans the GH- and ACTH-releasing activities of HEX undergo different age-related variations, and actions at different levels and/or on different hormonal subtypes of GHRPs are suggested.
