Identifying the predictive value of fractional exhaled nitric oxide (FeNO) for uncontrolled asthma in 3-7-year-old Thai children.

ABSTRACT:

Background

Fractional exhaled nitric oxide (FeNO) is the method for monitoring airway inflammation. However, a singular FeNO value cutoff may not adequately represent the control status across different ages and demographics. This study aimed to evaluate the correlation between FeNO values and asthma control levels, identifying an optimal cutoff point for children aged 3 to 7 years.

Methods

This cross-sectional study was conducted at Naresuan University Hospital from April 1, 2023 to July 31, 2023. Inclusion criteria were asthmatic patients aged 3 to 7 years who were capable of following commands. Exclusion criteria included children who had a coronavirus disease 2019 (COVID-19) infection, those experiencing difficulty breathing, or unable to perform the FeNO measurement. El
