[Somatotropin secretion during sleep. Application to partial somatotropin deficiency in the child]
Insights
Evaluating somatotropic secretion during sleep in children with growth backwardness revealed that sleep assessments identify more cases of partial growth hormone deficiency than pharmacological tests, aiding timely treatment. This research highlights the importance of sleep studies for diagnosing growth hormone disorders.
Area of Science:
- Pediatric Endocrinology
- Sleep Medicine
- Growth Hormone Research
Background:
- Children with growth backwardness may have somatotropic (growth hormone) secretion deficits.
- Accurate diagnosis is crucial for initiating timely treatment with human growth hormone.
Purpose of the Study:
- To investigate somatotropic secretion during sleep in children with significant growth backwardness.
- To compare the diagnostic utility of sleep-induced secretion versus diurnal pharmacological tests for growth hormone deficiency.
Main Methods:
- Studied sleep-induced somatotropic secretion in 122 children with growth backwardness (≥2 SD below mean).
- Compared sleep secretion patterns with results from diurnal pharmacological tests.
Main Results:
- Pharmacological tests indicated 73 normal, 49 partial STH secretion deficits.
- Sleep studies revealed normal secretion in 27 children initially suspected of partial deficit.
- Sleep studies identified a distinct group of 22 children with a true partial deficit requiring human growth hormone treatment.
Conclusions:
- Sleep-induced somatotropic secretion is a valuable tool for diagnosing growth hormone deficiency in children.
- Sleep secretion assessment can identify normal secretion in some children with suspected partial deficits, avoiding unnecessary treatment.
- This method helps to accurately diagnose and isolate children with partial growth hormone deficiency who benefit from human growth hormone therapy.
Abstract:
The authors studied somatotropic secretion during sleep in 122 children who had a backward growth of at last 2 standard deviations from the mean growth. Diurnal pharmacological tests showed 73 normal responses, 49 intermediate or dissociated responses orienting toward a partial deficit of STH secretion. The study of sleep secretion shows, among normal children, a secretory response superior to those pharmacological tests with a late secretory response in 20% of cases. In the group of children suspected of having a partial deficit, the study of sleep secretion permits to discover 27 children presenting a normal secretion, and to isolate a group of real partial deficit (22 children) who should have a treatment with the human growth hormone.
