The variability of responses to growth hormone therapy in children with short stature

Area of Science:

• Pediatric Endocrinology
• Growth Hormone Therapy
• Pediatric Growth Disorders

Background:

• Growth hormone (GH) is a standard treatment for children with short stature due to various growth disorders.
• While generally effective, there's growing concern about a significant rate of unsatisfactory responses to GH therapy.
• Poor response is often defined by inadequate changes in height standard deviation score and height velocity.

Purpose of the Study:

• To review the variability of responses to GH therapy across different approved growth disorders.
• To highlight the need for defining and addressing poor treatment responses.
• To guide optimal investigation and diagnosis-based GH therapy and dosage.

Main Methods:

• Review of existing literature on growth hormone therapy outcomes.
• Analysis of response variability in various pediatric growth disorders.
• Description of parameters for evaluating growth response and defining poor response.

Main Results:

• Responses to GH therapy vary considerably among different growth disorders.
• Evidence suggests an unacceptably high rate of poor or unsatisfactory catch-up growth in some children.
• Clear definitions and optimized regimens are needed to improve treatment efficacy.

Conclusions:

• Optimizing the investigation and diagnosis of children undergoing GH therapy is essential.
• Establishing clear definitions for poor response will aid in treatment adjustment.
• Tailoring GH therapy based on diagnosis and response parameters can improve outcomes for children with short stature.
