eCPAP Follow-up at School Age

October 5, 2026 updated by: Cynthia McEvoy

Extending Continuous Positive Airway Pressure (eCPAP) in Preterm Infants to Improve Long Term Lung Growth and Reduce Respiratory Morbidity at School Age: Follow-up of a Randomized Trial

The purpose of the study is to learn more about extended continuous positive airway pressure (eCPAP) in preterm infants that may be helpful for lung health. The investigators are hoping to find out if eCPAP in stable preterm infants in the NICU results in long lasting improvements of lung function in school aged children.

Detailed Description

This is an observational follow-up of former preterm children from the eCPAP radnomized controlled trial (NCT#04295564), a single-center study of eCPAP vs discontinue CPAP (dCPAP) in the neonatal intensive care unit at Oregon Health & Science University (OHSU). All former preterm infants randomized in the parent study will be approached for reconsent into this follow-up study. Investigartors will determine if eCPAP for stable preterm infants in the NICU results in sustained improvement of lung function (primary outcome spirometry) and less respiratory morbidity (wheeze), at school age. Investigators will determine if eCPAP in the NICU results in an airway tree with a larger cross- sectional area and greater lung volume at school age, which is associated with less respiratory morbidity. Additionally, investigators will obtain detailed biological data (DNA methylation and transcriptomics using nasal epithelium as a proxy for airway epithelium), to identify participants that share common molecular signatures (biological endotypes).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Sustained improvement of lung function (functional outcomes)
Time Frame: Between the ages of 6 and 8

Determine if eCPAP for preterm infants in the NICU results in sustained improvement of lung function (primary outcome spirometry) and less respiratory morbidity (wheeze) at school age.

Between the ages of 6 and 8

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Airway tree changes (structural outcomes)
Time Frame: Between the ages of 6 and 8

Determine via a single low dose high resolution computed tomography (HRCT) of the chest if eCPAP in the NICU results in an airway tree with a larger cross-sectional area and greater lung volume at school age, which is associated with less respiratory morbidity.

Between the ages of 6 and 8
Molecular Endotypes
Time Frame: Between the ages of 7 and 8

Detailed biological data (DNA methylation and transcriptomics using nasal epithelium as a proxy for airway epithelium), will be used to identify patients that share common molecular signatures (biological endotypes).

Between the ages of 7 and 8
