Effect of one month ketoconazole treatment on GH, cortisol and ACTH release after ghrelin, GHRP-6 and GHRH administration in patients with Cushing's disease.
GH responses to ghrelin, GHRP-6, and GHRH in Cushing's disease (CD) are markedly blunted. There is no data about the effect of reduction of cortisol levels with steroidogenesis inhibitors, like ketoconazole, on GH secretion in CD. ACTH levels during ketoconazole treatment are controversial. The aims of this study were to compare the GH response to ghrelin, GHRP-6, and GHRH, and the ACTH and cor...
متن کاملEffects of co-administration of ghrelin agonist (GHRP-2) and GH on TNF-α, IL-6 and iNOS gene expression induced by LPS in the mouse brain
The aim of this study was to examine the anti-inflammatory effects of co-administration of growthhormone-releasing peptide-2 (GHRP-2) and growth hormone (GH) on tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6) and inducible nitric oxide synthase (iNOS) gene expression induced by LPS in the mousebrain. Thirty-five male NMRI mice (25±5 g) were injected through the mouse tail vein with saline,...
متن کاملThe influence of serum cortisol levels on growth hormone responsiveness to GH-releasing hormone plus GH-releasing peptide-6 in patients with hypocortisolism.
The aim of this study was to evaluate the influence of circulating cortisol levels on the somatotroph responsiveness to the most potent stimuli of growth hormone (GH) secretion, the GHRH+GHRP-6 test. We studied 12 patients with hypocortisolism (10 with Addison's disease and 2 with isolated ACTH deficiency) before and after glucocorticoid (GC) replacement therapy and compared them with 14 health...
متن کاملNocturnal ghrelin, ACTH, GH and cortisol secretion after sleep deprivation in humans.
Ghrelin is an endogenous ligand of the growth hormone (GH) secretagogue (GHS) receptor. It is hypothesised to play a key role in energy balance stimulating food intake and body weight. Besides GH-releasing hormone (GHRH) and somatostatin, it is thought to be a regulating factor of GH release. Ghrelin also appears to be involved in sleep regulation. We showed recently that ghrelin promotes slow-...
متن کاملGH and cortisol rebound rise during and following a somatostatin infusion: studies in dogs with the use of a GH-releasing peptide.
GH-releasing peptides (GHRPs), a class of small synthetic peptide and non-peptide compounds, act on specific receptors at both the pituitary and the hypothalamic level to stimulate GH release in both humans and other animals. GHRPs, like corticotropin-releasing hormone (CRH), also possess acute ACTH- and cortisol-releasing activity, although the mechanisms underlying the stimulatory effect of G...
