Summary

Children with obstructive sleep apnoea (OSA) show elevated inflammatory markers, including Interferon-gamma (IFN-gamma) and Interleukin-8 (IL-8). These findings suggest a pro-inflammatory state even in mild OSA, highlighting the importance of early intervention.

Area of Science:

  • Pediatric Sleep Medicine
  • Immunology
  • Respiratory Medicine

Background:

  • Obstructive sleep apnoea (OSA) is a common condition in children.
  • Inflammation is increasingly recognized as a contributing factor in OSA.
  • Understanding inflammatory profiles in pediatric OSA is crucial for early diagnosis and management.

Purpose of the Study:

  • To investigate a spectrum of inflammatory markers in children diagnosed with OSA.
  • To compare inflammatory profiles between children with OSA and healthy controls.

Main Methods:

  • Polysomnography was used to diagnose OSA in 44 children.
  • Blood samples were analyzed for C-reactive protein and a panel of cytokines (IL-1beta to TNF-alpha).
  • 69 children without OSA symptoms served as controls.

Main Results:

  • Children with OSA exhibited significantly higher levels of Interferon-gamma (IFN-gamma) and Interleukin-8 (IL-8) compared to controls.
  • These differences remained significant after adjusting for age, sex, and body mass index.
  • No correlations were found between inflammatory markers and OSA severity or other sleep parameters.

Conclusions:

  • Mild pediatric OSA is associated with elevated IFN-gamma and a trend towards elevated IL-8, indicating a pro-inflammatory state.
  • These early inflammatory changes may precede those observed in adults with more severe OSA.
  • Early identification and intervention for OSA in children may be beneficial.
