GH deficiency status combined with GH receptor polymorphism affects response to GH in children
Meta-analysis has shown a modest improvement in first-year growth response to recombinant human GH (r-hGH) for carriers of the exon 3-deleted GH receptor (GHRd3) polymorphism but with significant interstudy variability. The associations between GHRd3 and growth response to r-hGH over 3 years in relation to severity of GH deficiency (GHD) were investigated in patients from 14 countries. Treatmen...
متن کاملGrowth hormone (GH) provocation tests and the response to GH treatment in GH deficiency.
OBJECTIVE To identify factors, particularly the growth hormone (GH) provocation test result, affecting growth response to GH treatment in children with GH deficiency (GHD). SUBJECTS A total of 337 prepubertal GHD patients aged <10 years from the UK Pharmacia KIGS database (GH response to provocation test <20 mU/l). OUTCOME MEASURE Annual change in height standard deviation score (SDS) (revi...
متن کاملThe cut-off limits of the GH response to GH-releasing hormone-arginine test related to body mass index.
OBJECTIVE The diagnosis of growth hormone (GH) deficiency (GHD) in adults is based on a reduced peak GH response to provocative tests, such as the insulin tolerance test (ITT) and the GH-releasing hormone-arginine (GHRH-ARG) test. However, the cut-off limits of peak GH response in lean subjects are not reliable in obese patients; this is noteworthy since adult GHD is often associated with obesi...
متن کاملLeptin is a potent stimulator of spontaneous pulsatile growth hormone (GH) secretion and the GH response to GH-releasing hormone.
Pulsatile GH secretion is exquisitely sensitive to perturbations in nutritional status, but the underlying mechanisms are largely unknown. Leptin, a recently discovered adipose cell hormone, is thought to be a sensor of energy stores and to regulate body mass, appetite, and metabolism at the level of the brain. Receptors for leptin are abundantly expressed in hypothalamic nuclei known to be inv...
متن کاملStereotactic Irradiation of GH-Secreting Pituitary Adenomas
Radiotherapy (RT) is often employed in patients with acromegaly refractory to medical and/or surgical interventions in order to prevent tumour regrowth and normalize elevated GH and IGF-I levels. It achieves tumour control and hormone normalization up to 90% and 70% of patients at 10-15 years. Despite the excellent tumour control, conventional RT is associated with a potential risk of developin...
