Nitric oxide in airway inflammation
… EBC collection device; 2) fractional exhaled NO (FENO) and EBC NOx in COPD patients would be altered by smoking and glucocorticosteroids (GCS); 3) cigarette smoke could contribute to the EBC NOx concentration while it may also decrease FENO indirectly by converting airway NO to NOx. It was found …

Development and validation of a diagnostic tool for occupational asthma based on serial lung function measurements
… more reproducible. Exhaled breath nitric oxide (FENO) showed similar ABC scores between those with normal and raised FENO. FENO was significantly correlated to methacholine reactivity. In shift workers, mean ABC scores were increased on morning shifts compared to nights, but the cut off of 15 …

Modification by sex and atopy of the effect of chemical air pollutions and biological air pollutants including pollen and fungal spores on children respiratory health in the Western Cape, Cape South Africa
… spirometry, and fractional exhaled nitric oxide (FeNO) testing. The study found that increased annual grass pollen levels and annual NO2 levels were positively associated with airway obstruction (OR: 2.26, 95% CI: 1.02-5.03) for annual grass pollen and FeNO (OR: 2.43, 95% CI:1.19-4.98) for annual …

Evidence for enhanced oxidative stress in smokers with severe asthma
… NOS2 mRNA expression in BBr correlated with FeNO (p< 0.001). FeNO was lower in current-smokers than in ex-smokers (p= 0.007) indicating an effect of active smoking. Conclusions The data suggests evidence of greater systemic oxidative stress in SAs/ex with significant effects on the mRNA …
