What is the Origin of Growth Hormone Intervention?

The concept of using growth hormone therapeutically originated with the purification of hGH from human pituitary glands in the 1950s, primarily for pediatric growth failure. The modern intervention became safer and more widespread after the development of recombinant DNA technology in the 1980s, allowing for the mass production of biosynthetic hGH. Clinical protocols for adult GHD have since been refined based on endocrinological research.

What is the Mechanism of Growth Hormone Intervention?

Administered hGH binds to receptors on target cells, most notably in the liver, stimulating the production and release of Insulin-like Growth Factor 1 (IGF-1). IGF-1 is the primary mediator of hGH's anabolic effects, driving protein synthesis, lipolysis, and cell proliferation in tissues like muscle, bone, and skin. The intervention essentially bypasses or supplements the body's natural, often declining, pulsatile release of endogenous growth hormone to restore the functional integrity of the somatotropic axis.

Growth Hormone Intervention

Meaning

Growth hormone intervention refers to the clinical administration of exogenous human growth hormone (hGH) or its secretagogues, such as Growth Hormone-Releasing Hormone (GHRH) analogues, typically to address a diagnosed growth hormone deficiency (GHD) in adults or children. In the adult context, the goal is to normalize the somatotropic axis to improve body composition, bone mineral density, and quality of life. This therapy requires careful endocrine monitoring due to its potent systemic effects on metabolism and the potential for adverse effects at supra-physiological doses.
