About this trial
Recent data support the existence of a GH-Agouti-related peptide (AgRP) axis. The neuropeptide AgRP promotes food intake and has important effects on energy homeostasis. Recent evidence suggest that GH stimulates AgRP and AgRP may mediate some of GH's important nutritional and metabolic effects. main goals of this project are to characterize, for the first time, plasma levels of AgRP in children and to determine how these relate to GH and IGF-1 levels, age, body composition, clinical and other endocrine parameters. To accomplish this, we will conduct two studies, one being a cross-sectional study that will measure AgRP levels in 140 healthy children ages 5-17 and the second being a prospective study that will measure the change in plasma AgRP levels in response to GH treatment in 16 children who receive this as part of their clinical care for GH deficiency or short stature.
