What is the Origin of Growth Hormone Replacement Therapy?

The therapy's origin dates back to the mid-20th century with the initial, albeit limited, use of human pituitary-derived growth hormone to treat children with growth failure. The advent of recombinant DNA technology in the 1980s allowed for the large-scale, safe production of synthetic human growth hormone, paving the way for its widespread application in both pediatric and adult deficiency states. The therapy is a prime example of modern biotechnological intervention in endocrinology.

What is the Mechanism of Growth Hormone Replacement Therapy?

Administered somatropin binds to specific growth hormone receptors on the surface of target cells, predominantly hepatocytes in the liver. This binding event activates the intracellular JAK2-STAT5 signaling pathway, which is the primary driver for the synthesis and secretion of Insulin-like Growth Factor 1 (IGF-1). IGF-1 then acts as the major anabolic hormone, stimulating protein synthesis in muscle, promoting lipolysis in adipose tissue, and supporting bone remodeling, thereby mediating the diverse physiological benefits of the replacement therapy.

Growth Hormone Replacement Therapy

Meaning

Growth Hormone Replacement Therapy (GHRT) is the clinical administration of recombinant human growth hormone (somatropin) to individuals diagnosed with a pathological deficiency of endogenous growth hormone (GH). In adults, this deficiency is typically secondary to pituitary or hypothalamic disease or damage, leading to Adult Growth Hormone Deficiency (AGHD). The therapeutic objective is to restore physiological levels of GH and its mediator, IGF-1, to normalize body composition, enhance bone mineral density, improve lipid profiles, and significantly increase the patient’s quality of life. Treatment requires meticulous endocrinological supervision and dose titration to avoid supraphysiological levels and potential adverse effects.
