To evaluate specific markers of cardiovascular risk before and after growth hormone replacement therapy in a population of growth hormone deficient adults, as compared to an age, gender, and BMI-matched healthy population.
Growth hormone deficiency (GHD) is associated with increased cardiovascular morbidity and mortality. The effects of such a deficiency include decreased exercise capacity and tolerance, impaired cardiac function, a central fat redistribution, increased peripheral arterial resistance, and an unfavorable lipid profile. These effects have been found to be reversed with appropriate replacement therapy with recombinant human growth hormone. We plan to utilize several experimental systems to further investigate the role of growth hormone (GH) in maintaining cardiovascular health. In particular, we would like to further understand the interaction of GH with Plasminogen-activator-inhibitor-1 (a major activator of the fibrinolytic system) as well as the role of GH in the maintenance of vascular function.

A 191-amino acid polypeptide hormone secreted by the human adenohypophysis (PITUITARY GLAND, ANTERIOR), also known as GH or somatotropin. Synthetic growth hormone, termed somatropin, has replaced the natural form in therapeutic usage such as treatment of dwarfism in children with growth hormone deficiency.
A form of dwarfism caused by complete or partial GROWTH HORMONE deficiency, resulting from either the lack of GROWTH HORMONE-RELEASING FACTOR from the HYPOTHALAMUS or from the mutations in the growth hormone gene (GH1) in the PITUITARY GLAND. It is also known as Type I pituitary dwarfism. Human hypophysial dwarf is caused by a deficiency of HUMAN GROWTH HORMONE during development.
An autosomal recessive disorder characterized by short stature, defective GROWTH HORMONE RECEPTOR, and failure to generate INSULIN-LIKE GROWTH FACTOR I by GROWTH HORMONE. Laron syndrome is not a form of primary pituitary dwarfism (GROWTH HORMONE DEFICIENCY DWARFISM) but the result of mutation of the human GHR gene on chromosome 5.
A pituitary tumor that secretes GROWTH HORMONE. In humans, excess HUMAN GROWTH HORMONE leads to ACROMEGALY.
A polypeptide that is secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Growth hormone, also known as somatotropin, stimulates mitosis, cell differentiation and cell growth. Species-specific growth hormones have been synthesized.
