The study of fractional exhaled nitric oxide in newly diagnosed cases of bronchial asthma and chronic obstructive pulmonary disease

Indian Journal of Allergy Asthma and Immunology, 2021
INTRODUCTION: Fractional exhaled nitric oxide (FENO) is a measurement of fractional nitric oxide (NO) concentration in exhaled breath. It is a quantitative, noninvasive, simple, and safe method to measure airway inflammation for the assessment of airways

Fractional exhaled nitric oxide in asthma: an update [PDF]

Respirology, 2009
ABSTRACTIn asthma, clinical symptoms and lung function are insensitive in reflecting the underlying airway inflammation, and monitoring of this process has only recently become available. Fractional exhaled nitric oxide (FeNO) is now recognized as a reliable surrogate marker of eosinophilic airway inflammation and offers the advantage of being ...

Treatment guided by fractional exhaled nitric oxide in addition to standard care in 6- to 15-year-olds with asthma: the RAACENO RCT

Efficacy and Mechanism Evaluation, 2022
Background: The role of fractional exhaled nitric oxide in guiding asthma treatment in children is uncertain. Objective: To compare treatment guided by both fractional exhaled nitric oxide and symptoms (intervention) with treatment guided by symptoms ...

NO kidding: exhaled nitric oxide fraction in preschool children [PDF]

European Respiratory Journal, 2014
Wheeze is one of the most prevalent symptoms in preschool children with huge impacts on children and their families, on healthcare utilisation and hence costs [1]. While most children will become asymptomatic by 5–6 years of age, some will develop asthma or, even more importantly, severe problematic asthma and/or will experience an accelerated decline ...

Genetic loci for lung function in Japanese adults with adjustment for exhaled nitric oxide levels as airway inflammation indicator

Communications Biology, 2021
Yamada, Motoike, Kojima et al. undertake a GWAS study on 19,722 participants from two Japanese populations for lung function with adjustment for fractional exhaled nitric oxide levels to account for airway inflammation.

Elevated exhaled nitric oxide in allergen-provoked asthma is associated with airway epithelial iNOS.

PLoS ONE, 2014
BackgroundFractional exhaled nitric oxide is elevated in allergen-provoked asthma. The cellular and molecular source of the elevated fractional exhaled nitric oxide is, however, uncertain.ObjectiveTo investigate whether fractional exhaled nitric oxide is

Effect of Inhaled β2-Agonist on Exhaled Nitric Oxide in Chronic Obstructive Pulmonary Disease. [PDF]

PLoS ONE, 2016
The fractional exhaled nitric oxide measured at an expiratory flow of 50mL/s (FENO50) is a marker of airway inflammation, and high levels are associated with greater response to steroid treatment.

The Fraction Exhaled Nitric Oxide as a Biomarker of Asthma Control [PDF]

Biomarker Insights, 2019
Introduction and Objective: The main goal of asthma treatment is to achieve and maintain clinical control of the disease. The exhaled fraction nitric oxide (FeNO) level is a biomarker of T-helper cell type 2 (Th2) inflammation of the airways.

Influence of oral care on fractional exhaled nitric oxide [PDF]

Asia Pacific Allergy, 2018
Fractional exhaled nitric oxide (FeNO) is an indicator of bronchial inflammation in asthma patients. However, nitric oxide is also produced in the oral cavity, with production depending on the local anaerobic flora and intraoral acidity.To evaluate the influence of oral care on measurement of FeNO, to investigate the influence of sleep when the oral ...

Determinants of Children's Exhaled Nitric Oxide: New Insights from Quantile Regression. [PDF]

PLoS ONE, 2015
While the fractional concentration of exhaled nitric oxide (FeNO) has proven useful in asthma research, its exact role in clinical care remains unclear, in part due to unexplained inter-subject heterogeneity.
