Question 1

What is the Meaning of Long-Term GH Therapy?

Accepted Answer

Long-Term GH Therapy refers to the sustained therapeutic administration of recombinant human growth hormone (rhGH) over an extended period, typically spanning several years. This medical intervention is prescribed to address various conditions characterized by inadequate endogenous growth hormone secretion or specific medical indications that benefit from its anabolic and metabolic effects.

Question 2

What is the Context of Long-Term GH Therapy?

Accepted Answer

This therapy functions within the complex framework of the somatotropic axis, directly influencing anabolic processes and metabolic regulation throughout the human body. It primarily addresses disruptions in endogenous growth hormone secretion, which originates from the anterior pituitary gland and plays a pivotal role in childhood linear growth, body composition maintenance, and adult metabolic health.

Question 3

What is the Significance of Long-Term GH Therapy?

Accepted Answer

Long-term GH therapy holds substantial clinical importance for pediatric patients with growth hormone deficiency, promoting linear growth and facilitating the achievement of appropriate adult height. In adult patients, it mitigates symptoms associated with acquired or congenital GH deficiency, such as altered body composition, reduced bone mineral density, and impaired quality of life, thereby optimizing physiological function and reducing long-term morbidity.

Question 4

What is the Mechanism of Long-Term GH Therapy?

Accepted Answer

Exogenously administered growth hormone binds to specific growth hormone receptors located on target cells throughout the body, including hepatocytes, adipocytes, and muscle cells. This binding initiates intracellular signaling cascades, most notably stimulating the hepatic production of insulin-like growth factor 1 (IGF-1), which mediates many of GH's anabolic and metabolic effects, promoting cellular proliferation and tissue repair.

Question 5

What is the Application of Long-Term GH Therapy?

Accepted Answer

Clinical application of long-term GH therapy typically involves daily subcutaneous injections of recombinant human growth hormone, with dosing individualized based on patient age, weight, and clinical response. Treatment protocols are meticulously adjusted to achieve therapeutic targets while minimizing potential adverse effects, necessitating regular medical oversight and patient education regarding proper administration techniques.

Question 6

What is the Metric of Long-Term GH Therapy?

Accepted Answer

Monitoring the efficacy and safety of long-term GH therapy involves serial assessments of serum IGF-1 levels, which serve as a crucial biomarker reflecting systemic GH activity. In pediatric patients, linear growth velocity and bone age are routinely evaluated to track progress, while adult patients undergo assessments of body composition, lipid profiles, and bone mineral density to gauge therapeutic impact and overall metabolic health.

Question 7

What is the Risk of Long-Term GH Therapy?

Accepted Answer

Potential risks associated with long-term GH therapy include peripheral edema, arthralgia, carpal tunnel syndrome, and an increased risk of glucose intolerance or new-onset diabetes mellitus, particularly at higher doses or in predisposed individuals. Careful patient selection, vigilant monitoring of metabolic parameters, and dose titration are essential to mitigate these potential adverse events and ensure the safety of treatment.
