Insights
Adenotonsillectomy (AT) in children with obstructive sleep apnea hypopnea syndrome (OSAHS) improved bone age and serum osteocalcin levels. These markers were lower in OSAHS patients pre-surgery and correlated with OSAHS severity.
Area of Science:
- Pediatric Endocrinology
- Sleep Medicine
- Biochemistry
Background:
- Obstructive sleep apnea hypopnea syndrome (OSAHS) in children can impact growth and development.
- Serum osteocalcin is a key biomarker for bone metabolism.
- Bone age assessment provides insights into skeletal maturation.
Purpose of the Study:
- To investigate changes in bone age and serum osteocalcin levels in children with OSAHS before and after adenotonsillectomy (AT).
- To explore the correlation between bone age, serum osteocalcin, and OSAHS severity indicators.
Main Methods:
- A cohort of 58 children diagnosed with OSAHS underwent assessment of bone age (X-ray) and serum osteocalcin levels (ELISA) pre- and 6-months post-AT.
- Statistical analysis was performed using SPSS 19.0.
- Correlations were examined with apnea-hypopnea index, oxygen desaturation index, and Epworth sleepiness scale scores.
Main Results:
- OSAHS patients exhibited significantly lower bone age and serum osteocalcin levels compared to normal controls prior to AT (P < 0.05).
- Following AT, both bone age and serum osteocalcin levels significantly increased in OSAHS patients (P < 0.05).
- Lower bone age and serum osteocalcin levels were negatively correlated with OSAHS severity indices (P < 0.05).
Conclusions:
- Bone age and serum osteocalcin levels may be linked to the pathogenesis of pediatric OSAHS.
- Adenotonsillectomy appears to be an effective intervention for improving bone maturation and osteocalcin levels in children with OSAHS.
Abstract:
Our aim was to study the changes in bone age and serum osteocalcin levels before and after adenotonsillectomy (AT) in children with obstructive sleep apnea hypopnea syndrome (OSAHS). A total of 58 OSAHS children (37 males and 21 females) with the mean age of 6.68 ± 1.11 years were enrolled and assessed by x-ray-based bone age estimation and enzyme-linked immunosorbent assay-based measurement of serum osteocalcin levels, before surgery and 6 months after AT. SPSS 19.0 software was used for statistical analysis. Our results revealed that bone age and serum osteocalcin levels in OSAHS patients were significantly lower than normal controls before AT (P < 0.05). Within 6 months after surgery, the bone age and the serum osteocalcin levels were significantly elevated in OSAHS patients (P < 0.05), compared with those before surgery. Serum osteocalcin levels and bone age are negatively correlated with apnea-hypopnea index, oxygen desaturation index, the percentage of the total recorded time spent below 90% oxygen saturation, and Epworth sleepiness scale scores (all P < 0.05). Our findings suggested that bone age and serum osteocalcin levels may be correlated with the development of OSAHS in children. AT may improve bone age and serum osteocalcin levels in OSAHS children.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
