Insights
Growth hormone (GH) therapy can normalize the timing of puberty in children with cystic fibrosis (CF). This study found that GH treatment helps initiate normal pubertal development in prepubertal males and females with CF.
Area of Science:
- Pediatric Endocrinology
- Cystic Fibrosis Research
- Growth Hormone Therapy
Background:
- Children with cystic fibrosis (CF) frequently experience delayed puberty and impaired growth.
- Growth hormone (GH) is a potential therapeutic agent for addressing these issues.
Purpose of the Study:
- To evaluate the effect of GH treatment on pubertal maturation in children with CF.
- To determine if GH therapy can normalize the onset and progression of puberty in this population.
Main Methods:
- Retrospective analysis of pubertal maturation data from 105 children with CF.
- Data collected from participants in studies involving GH treatment (1 year on GH, followed by off GH, or vice versa).
- Pubertal staging assessed throughout the study periods.
Main Results:
- GH treatment normalized the onset of breast development in prepubertal females with CF.
- Females treated with GH during puberty experienced normal breast development tempo.
- GH treatment normalized the onset of testicular volume in prepubertal males with CF.
- GH did not accelerate testicular size progression in pubertal males with CF.
Conclusions:
- Growth hormone therapy effectively normalizes pubertal onset in prepubertal children diagnosed with cystic fibrosis.
- GH treatment represents a viable strategy to address pubertal delays in pediatric CF patients.
Unlabelled:
Children with cystic fibrosis (CF) have a high incidence of delayed puberty and poor growth. We retrospectively reviewed pubertal maturation data from 105 children with CF who had participated in studies on growth hormone (GH). As part of the GH study, participants were randomized into two cohorts, one of which was treated with GH for 1 year, and then followed off GH, and the other group was first followed off GH, and then treated with GH for 1 year. Pubertal staging was obtained throughout these studies and we have retrospectively analyzed the data.
Results:
In prepubertal females, GH treatment resulted in a normalized onset of breast development as compared to delayed onset in non-treated females. Females treated during puberty had a normal tempo of breast development. In prepubertal males, GH treatment resulted in a normalized onset of testicular volume compared to non-treated males. Testicular size progression was not accelerated in pubertal boys treated with GH.
Conclusion:
GH treatment normalizes pubertal onset in prepubertal children with CF.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
