Question 1

What is the Meaning of rhGH Therapy?

Accepted Answer

rhGH Therapy refers to the therapeutic administration of recombinant human growth hormone, a synthetic protein structurally identical to naturally occurring somatotropin, primarily used to replace deficient endogenous growth hormone or to stimulate growth in specific medical conditions. This medical intervention aims to restore physiological growth patterns and metabolic functions.

Question 2

What is the Context of rhGH Therapy?

Accepted Answer

This therapy operates within the broader endocrine system, specifically targeting pathways regulated by the hypothalamic-pituitary-somatotropic axis. Growth hormone, naturally secreted by the anterior pituitary gland, plays a crucial role in cellular reproduction, tissue repair, and metabolism throughout the body, influencing bone density, muscle mass, and fat distribution.

Question 3

What is the Significance of rhGH Therapy?

Accepted Answer

rhGH Therapy holds significant clinical importance for individuals experiencing growth hormone deficiency, often leading to improved linear growth in pediatric patients and enhanced body composition, bone mineral density, and quality of life in adults. Its application can mitigate the long-term health complications associated with untreated somatotropin insufficiency, contributing to overall physiological well-being.

Question 4

What is the Mechanism of rhGH Therapy?

Accepted Answer

The mechanism of rhGH action involves binding to specific growth hormone receptors located on target cells throughout the body, including hepatocytes, adipocytes, and muscle cells. This binding initiates intracellular signaling cascades, predominantly stimulating the liver to produce Insulin-like Growth Factor-1 (IGF-1), which then mediates many of growth hormone's anabolic and metabolic effects, promoting cellular proliferation and differentiation.

Question 5

What is the Application of rhGH Therapy?

Accepted Answer

Clinically, rhGH Therapy is typically administered via daily subcutaneous injections, with dosages carefully titrated based on patient age, diagnosis, and individual response, often guided by IGF-1 levels. Its primary applications include treating pediatric growth hormone deficiency, Turner syndrome, Prader-Willi syndrome, chronic kidney disease, and adult growth hormone deficiency, aiming to normalize growth and metabolic parameters.

Question 6

What is the Metric of rhGH Therapy?

Accepted Answer

Monitoring the effectiveness and safety of rhGH Therapy involves regular assessment of serum IGF-1 levels, which serve as a primary biochemical marker reflecting systemic growth hormone activity. Additionally, linear growth velocity and bone age are routinely evaluated in pediatric patients, while adults undergo assessments of body composition, lipid profiles, and bone mineral density to gauge therapeutic response and adjust dosing.

Question 7

What is the Risk of rhGH Therapy?

Accepted Answer

Despite its therapeutic benefits, rhGH Therapy carries potential risks, including fluid retention, arthralgia, myalgia, and carpal tunnel syndrome, particularly in adults. Glucose intolerance or new-onset diabetes can occur due to its metabolic effects, necessitating careful glucose monitoring. Contraindications include active malignancy, acute critical illness, and proliferative retinopathy in diabetic patients, underscoring the importance of strict medical supervision and patient selection.
