[Clinical use of growth hormone and clonidine in growth disorders]
Insights
Recombinant growth hormone (GH) effectively treats GH deficiency in children. Clonidine aids GH secretion in constitutional growth delay but is less effective for familial short stature.
Area of Science:
- Pediatric Endocrinology
- Pharmacology
- Growth Disorders
Context:
- Prepubertal children with growth disorders present unique diagnostic and therapeutic challenges.
- Evaluating the efficacy of growth hormone (GH) and clonidine in pediatric growth conditions is crucial.
Purpose:
- To assess the therapeutic effects of recombinant human growth hormone (rhGH) and the alpha-2 adrenergic agonist clonidine in prepubertal children with distinct growth disorders.
- To compare the efficacy of these treatments across different pediatric growth conditions.
Summary:
- Recombinant human growth hormone (rhGH) demonstrated significant growth-promoting effects in children with GH deficiency.
- Clonidine administration successfully restored GH secretion in children experiencing constitutional delay of growth.
- However, clonidine exhibited minimal to no efficacy in children with familial short stature.
Impact:
- This study provides evidence for the targeted application of rhGH and clonidine in pediatric growth management.
- Findings guide clinical decisions regarding the treatment of short stature in prepubertal children.
- Highlights the differential response to clonidine based on the etiology of short stature.
Abstract:
The aim of this study was to investigate the effects of the recombinant human growth hormone and of the alpha-2 adrenergic agonist clonidine in three groups of prepuberal children with growth disorders. Three children with GH-deficiency were treated with 0.5 U kg/week i.m. of recombinant growth hormone; 13 children (7 with constitutional delay of growth and 6 with familiar short stature) were treated with 0.08 mg/m2/die per os of clonidine. The results confirmed the growth promoting effect of GH in GH-deficiency. Clonidine restored GH-secretion in children with constitutional delay, but had a very poor or no effect in familiar short children.
