GHRP-2 preserved growth hormone secretion in 8 children on prednisone therapy, overcoming the steroid-induced GH suppression that typically impairs growth.
GH preserved in childrenGHRP-2 maintained GH secretory response during prednisone therapy in 8 children, bypassing steroid-induced suppression
What the researchers found
GHRP-2 preserved GH secretory response in 8 children during prednisone therapy, maintaining GH release levels comparable to pre-treatment baseline, suggesting GHRP-2 bypasses glucocorticoid-induced somatostatin excess.
Why it matters
Thousands of children need chronic steroids for asthma, arthritis, and other conditions. Preserving their GH function could prevent the growth stunting that currently accompanies steroid treatment.
How the study worked
Clinical trial in 8 children requiring prednisone therapy. GH stimulation tests with GHRP-2 were performed before and during prednisone treatment. GH peak levels and secretory patterns were compared.
What this study cannot tell us
Very small study (8 children). GH stimulation test results don't guarantee actual growth preservation. Long-term growth outcomes not assessed. Open-label design.
How to read the evidence
Moderate evidence from a small clinical study in the relevant patient population, with physiological endpoints but no growth outcome data.
When this study was published
Published in 1999. The concept of using GH secretagogues to preserve growth during steroid therapy remains clinically relevant but has not yet led to approved treatments.
The bigger picture
The ability to maintain GH function during necessary steroid treatment could change the risk-benefit calculation for pediatric steroid use. Children could receive the anti-inflammatory benefits without sacrificing growth.
Questions still open
- Does preserved GH secretion translate to maintained linear growth?
- What is the optimal GHRP-2 dose for growth preservation during steroid therapy?
- Would chronic GHRP-2 administration maintain its effectiveness long-term?
Common questions
Why do steroids affect children's growth?
Could GHRP-2 help children on steroids grow normally?
