Bronchial asthma is an airway disorder associated with bronchial hyperresponsiveness,
variable airflow obstruction and elevated levels of nitric oxide (NO) in exhaled air. The …

Background: Asthma guidelines emphasize maintaining disease control. However, objective
measures of asthma disease control are lacking. Objective: We sought to examine the …

Exhaled nitric oxide (NO) has attracted increasing interest as a non-invasive marker of
airway inflammation. The purpose of this study was to determine whether exhaled nitric …

The measurement of exhaled nitric oxide (ENO) is recognized as a marker of airway
inflammation. ENO was measured in 10 nonsteroid-treated asthmatics at recruitment, during …

BACKGROUND Exhaled levels of nitric oxide (NO) are raised in asthma but the relationship
between exhaled NO levels and a direct measure of airway inflammation has not been …

Exhaled nitric oxide fraction (F eNO), which is a reliable marker of eosinophilic airway
inflammation, is partially suppressed by tobacco smoking. Consequently, its potential as a …

The fraction of exhaled nitric oxide (FeNO) is elevated in asthmatics compared to normal
subjects. Many studies have demonstrated that FeNO correlates with other markers of …

Background: The concentration of exhaled nitric oxide ([NO]) has been reported to reflect the
inflammatory process of airways in patients with bronchial asthma, particularly when they …

Exhaled nitric oxide (NO) has been suggested to be a marker of airway inflammation. The
aim of this study was to evaluate the role of exhaled NO in bronchial asthma and chronic …

Objective: Exhaled nitric oxide (eNO) has been used as a surrogate of airway inflammation
in mild asthma. However, whether eNO levels reflect disease activity in symptomatic …
