Question 1

What is the Meaning of rhGH?

Accepted Answer

Recombinant human Growth Hormone (rhGH) is a synthetic somatotropin. This bioengineered protein mimics natural human growth hormone structure and activity. It is manufactured via recombinant DNA technology for therapeutic use.

Question 2

What is the Context of rhGH?

Accepted Answer

Within the endocrine system, rhGH functions as a vital signaling molecule. It integrates into the hormonal network governing somatic growth, cellular proliferation, and tissue regeneration. Its actions regulate metabolism of proteins, lipids, and carbohydrates, influencing body composition and energy balance.

Question 3

What is the Significance of rhGH?

Accepted Answer

RhGH holds substantial clinical importance for insufficient endogenous growth hormone. In pediatric endocrinology, it treats growth hormone deficiency, preventing severe short stature. For adults with pituitary insufficiency, rhGH therapy improves bone mineral density, optimizes body composition, and enhances metabolic health, improving quality of life.

Question 4

What is the Mechanism of rhGH?

Accepted Answer

RhGH exerts effects by binding to specific growth hormone receptors on target cells. This activates intracellular signaling, notably the JAK-STAT pathway. This prompts the liver to synthesize and release Insulin-like Growth Factor 1 (IGF-1), mediating many of growth hormone's anabolic actions. Direct effects on lipolysis and glucose homeostasis are also observed.

Question 5

What is the Application of rhGH?

Accepted Answer

Clinical rhGH administration involves subcutaneous injection, often daily or several times weekly, tailored to patient diagnosis and objectives. Protocols involve dose titration guided by clinical response and serum IGF-1 levels. Primary applications include pediatric growth disorders, adult growth hormone deficiency, and specific genetic syndromes like Turner syndrome, aiding health progression.

Question 6

What is the Metric of rhGH?

Accepted Answer

Monitoring rhGH therapy effectiveness relies on specific biomarkers and clinical parameters. Serum IGF-1 concentrations are a key biochemical marker, reflecting systemic growth hormone activity and guiding dose adjustments. For children, linear growth velocity is crucial. In adults, assessments include body composition changes, bone mineral density, and metabolic markers. Regular medical evaluation ensures optimal outcomes.

Question 7

What is the Risk of rhGH?

Accepted Answer

While generally well-tolerated, rhGH therapy carries potential adverse effects. These include fluid retention (edema, arthralgia), carpal tunnel syndrome, and decreased insulin sensitivity, potentially increasing glucose intolerance risk. Unsupervised or excessive administration can lead to acromegaly-like symptoms or other endocrine imbalances. Careful patient selection, precise dosing, and continuous endocrinologist oversight are paramount to mitigate concerns.
