Insights
Positive airway pressure (PAP) therapy effectively reduces obstructive sleep apnea (OSA) in children, with an 85% median AHI reduction. However, individual responses vary, influenced by OSA severity, PAP levels, sex, and obesity.
Area of Science:
- Pediatric Sleep Medicine
- Respiratory Medicine
- Clinical Data Analysis
Background:
- Positive airway pressure (PAP) therapy is crucial for managing pediatric obstructive sleep apnea (OSA).
- Limited data exist on real-world PAP therapy responses in children.
- Home monitoring offers a valuable tool for assessing pediatric PAP effectiveness.
Purpose of the Study:
- To evaluate real-world PAP therapy responses in children with OSA using home monitoring data.
- To identify factors predicting individual patient responses to PAP therapy.
Main Methods:
- Analysis of PAP therapy data from 195 children (1 month to 18 years) with OSA.
- Comparison of baseline apnea-hypopnea index (AHI) from polysomnography with PAP device data.
- Multivariate logistic regression to determine predictors of a positive PAP response (≥75% AHI reduction).
Main Results:
- Children showed excellent median AHI reduction of 85% with PAP therapy.
- Significant heterogeneity in AHI reduction was observed among patients.
- Higher PAP levels, more severe OSA, obesity, and female sex were associated with better PAP response.
Conclusions:
- Real-world data confirm PAP therapy's effectiveness in children with OSA, despite response variability.
- Predictive models incorporating OSA parameters and individual factors can optimize home-based PAP therapy.
Study Objectives:
The use of positive airway pressure (PAP) in children is a complex process determined by multiple factors. There are limited data on the response of the pediatric population to PAP therapy at home. The goal of the study was to examine real-world responses using PAP home monitoring in children with obstructive sleep apnea.
Methods:
The study included PAP therapy data for 195 children aged between 1 month and 18 years with obstructive sleep apnea and polysomnogram baseline study. We collected demographics, clinical variables, and polysomnogram parameters in all study participants. The individual response to PAP therapy was calculated comparing the apnea-hypopnea index (AHI) in the initial polysomnogram with the mean AHI provided by the download of PAP devices. Multivariate models (logistic regression) were used to examine the predictors of positive PAP response defined as a reduction in AHI ≥ 75%.
Results:
We found excellent responses to PAP therapy in children (median 85% AHI reduction). However, there was substantial heterogeneity in AHI reductions while on PAP therapy. The best PAP responses were linked to more severe obstructive sleep apnea and higher PAP levels. We also identified that the response to PAP was higher in obese children and lower in males. The best predictive model for individual PAP response was biological sex, obesity, and obstructive AHI ≥ 20 events/h (area under the receiver operating characteristic curve of 0.791).
Conclusions:
Real-world data show that PAP is overall an effective therapy in children but the response is heterogeneous. Obstructive sleep apnea parameters and individual factors can be used to predict individual AHI reductions while on PAP and optimize PAP responses at home.
