Insights

A new nomogram helps identify children with moderate-to-severe obstructive sleep apnea (OSA) using clinical and inflammatory markers. This tool aids early diagnosis and intervention when polysomnography (PSG) is unavailable.

Area of Science:

  • Pediatric Sleep Medicine
  • Biomarker Discovery
  • Clinical Prediction Modeling

Background:

  • Polysomnography (PSG) is the gold standard for diagnosing pediatric obstructive sleep apnea (OSA), but its limited accessibility hinders early identification of severe cases.
  • Accurate and timely diagnosis is crucial for effective intervention in children with moderate-to-severe OSA.

Purpose of the Study:

  • To develop an interpretable clinical prediction model for early identification of moderate-to-severe pediatric OSA.
  • To distinguish moderate-to-severe pediatric OSA from mild OSA using accessible clinical and inflammatory biomarkers.

Main Methods:

  • Retrospective study of 164 children diagnosed with OSA via PSG.
  • Least Absolute Shrinkage and Selection Operator (LASSO) regression to select predictive features.
  • Multivariable logistic regression model presented as an interpretable nomogram, validated with bootstrap analysis.

Main Results:

  • Eight core predictors identified: female sex, tonsil size (grades 3-4), adenoid-to-nasopharynx ratio (A/N ratio), IgE, IL-4, IL-6, and IL-10.
  • The final model achieved a bootstrap-corrected AUC of 0.763 (95% CI 0.690-0.836).
  • Decision curve analysis confirmed the model's clinical utility for risk assessment.

Conclusions:

  • An explainable nomogram was developed integrating upper airway anatomy, allergic status, sex, and inflammatory cytokines (IL-4, IL-6, IL-10).
  • This tool offers a practical, non-invasive method for individualized risk assessment of moderate-to-severe OSA in children.
  • Facilitates prioritized diagnosis and intervention for children with moderate-to-severe OSA.
