Question 1

What is the Meaning of rhGH Treatment?

Accepted Answer

rhGH Treatment involves the therapeutic administration of recombinant human growth hormone, a synthetic analog of pituitary-derived somatotropin. This medical intervention supplements insufficient endogenous hormone production, aiming to restore physiological growth and metabolic functions in individuals with specific medical conditions.

Question 2

What is the Context of rhGH Treatment?

Accepted Answer

Within the complex regulatory system of the endocrine network, rhGH Treatment mimics somatotropin, the growth hormone naturally produced by the anterior pituitary gland. Its biological context involves regulating somatic growth during development and influencing metabolic processes like protein synthesis, lipid metabolism, and glucose homeostasis, often mediated by IGF-1.

Question 3

What is the Significance of rhGH Treatment?

Accepted Answer

The clinical significance of rhGH Treatment is substantial for patients with growth hormone deficiency, pediatric and adult. For children, it addresses short stature, promoting linear growth. In adults, its application mitigates GHD symptoms like altered body composition, reduced bone mineral density, and impaired lipid profiles, improving physiological state.

Question 4

What is the Mechanism of rhGH Treatment?

Accepted Answer

The therapeutic mechanism of rhGH involves binding to specific growth hormone receptors on target cells. This initiates intracellular signaling, predominantly via the JAK-STAT pathway, stimulating synthesis and secretion of insulin-like growth factor 1 (IGF-1) from the liver. IGF-1 mediates many anabolic and growth-promoting effects, alongside direct GH actions.

Question 5

What is the Application of rhGH Treatment?

Accepted Answer

Clinically, rhGH Treatment is typically administered via daily subcutaneous injections, often at bedtime to mimic natural pulsatile GH secretion. Dosing protocols are highly individualized, determined by patient age, weight, condition, and therapeutic response, guided by serum IGF-1 levels. This long-term therapy requires consistent adherence and regular endocrinologist monitoring to optimize outcomes.

Question 6

What is the Metric of rhGH Treatment?

Accepted Answer

Monitoring rhGH Treatment efficacy and safety involves key metrics. Serum IGF-1 levels are a primary biochemical marker, reflecting systemic response and guiding dose adjustments within an age-appropriate range. In pediatric patients, linear growth velocity and bone age assessments are critical. For adults, body composition, lipid profiles, and glucose metabolism are evaluated with clinical symptom assessment.

Question 7

What is the Risk of rhGH Treatment?

Accepted Answer

While generally well-tolerated, rhGH Treatment carries potential risks and side effects requiring careful clinical oversight. Adverse effects include fluid retention, peripheral edema, carpal tunnel syndrome, and musculoskeletal discomfort. Less common serious risks involve increased intracranial pressure, especially in pediatric patients, and potential glucose intolerance or diabetes. It is strictly contraindicated in active malignancy due to its potential to stimulate tumor growth, requiring thorough patient selection and ongoing medical surveillance.
