The purpose of the research is to learn more about how the lining of arteries in the body (called the endothelium) is affected by growth hormone treatment in children and adolescents. Poor function by the blood vessels is associated with increased risk of heart disease or stroke. This research is being done because growth hormone treatment has been shown to make the endothelium work better in adults. Growth hormone treatment may have the same or different effects in children because the dose is larger in children.
Children between 8 and 18 years who are to be started on growth hormone will be eligible to participate. Blood vessel function will be studied before starting growth hormone and 3 months after. This will be done by measuring blood flow to the arm before and after 5 min of stopping blood flow to the arm. The three months of growth hormone will be given free.

You may be eligible if
isolated growth hormone deficiency (peak growth hormone level less than 10 ng/ml in response to arginine-insulin stimulation with cortisol responses and thyroid function tests), panhypopituitarism with appropriate thyroxine (normal free T4 level) and cortisol replacement (8-12 mg/m2/day) and non classic growth hormone deficiency (growth velocity less than 5 cm/year; peak growth hormone \>10 ng/ml).
You may not be if
Taking medications other than the appropriate hormonal replacement(L-thyroxine, cortisol, estrogen or testosterone, DDAVP)
