Introduction Measurements of eosinophils in induced sputum and fractional exhaled nitric
oxide (FeNO) are noninvasive biomarkers for assessing airway inflammation phenotypes in …

Fractional exhaled nitric oxide (FENO) may be a pulmonary biomarker in chronic obstructive
pulmonary disease (COPD). In this prospective study, the relationship between FENO and …

Purpose Fractional exhaled nitric oxide (FENO50) level and peripheral blood eosinophil
count may serve as indicators of airway eosinophilia. The aim of this study was to estimate …

Purpose Chronic obstructive pulmonary disease (COPD) with eosinophilic airway
inflammation may represent a unique phenotype, possibly with shared features of COPD …

Background: The use of fractional exhaled nitric oxide (FeNO) has been proposed for
identifying and monitoring eosinophilic airway inflammation in chronic obstructive …

The fractional concentration of exhaled nitric oxide (FeNO) is recognized as a biomarker of
type 2 inflammation in asthma, which is related to airway eosinophilia. We conducted a …

Background Sputum eosinophil and fractional exhaled nitric oxide (FeNO), noninvasive
biomarkers of local eosinophilic airway inflammation, can be used to assess asthma …

The value of fractional exhaled nitric oxide (FeNO) in patients with chronic obstructive
pulmonary disease (COPD) remains unclear. We aimed to assess whether FeNO is a more …

Background: Fractional exhaled Nitric Oxide concentration (FeNO) is a measure of airway
inflammation. It is being used increasingly in asthma as a biomarker for eosinophilic airway …

Some patients with chronic obstructive pulmonary disease (COPD) have eosinophilic
inflammation which may be evaluated via the measurement of fractional exhaled nitric oxide …
