Environmental Effects on Fractional Exhaled Nitric Oxide in Allergic Children [PDF]

Journal of Allergy, 2012
Fractional exhaled nitric oxide (FeNO) is a non-invasive marker of airway inflammation in asthma and respiratory allergy. Environmental factors, especially indoor and outdoor air quality, may play an important role in triggering acute exacerbations of respiratory symptoms. The authors have reviewed the literature reporting effects of outdoor and indoor

Fractional exhaled nitric oxide monitoring in paediatric asthma management [PDF]

British Journal of General Practice, 2017
An annual review is recommended for children with asthma but objective measures of control are lacking.1 Monitoring exacerbations and a symptom score are both suggested, but the widely used Children’s Asthma Control Test (C-ACT) has a positive predictive value of only 46.7% for asthma exacerbations at the recommended score of

Effects of the Indoor Environment on the Fraction of Exhaled Nitric Oxide in School-Aged Children

Canadian Respiratory Journal, 2009
BACKGROUND: The fractional concentration of exhaled nitric oxide (FeNO) appears to be a good marker for airway inflammation in children with asthma.

Measurement of Fractional Exhaled Nitric Oxide in Stable Bronchiectasis

Tuberculosis and Respiratory Diseases, 2013
Fractional exhaled nitric oxide (FeNO) can be measured easily, rapidly, and noninvasively for the assessment of airway inflammation, particularly mediated by eosinophil, such as asthma. In bronchiectasis (BE), the pathogenesis has been known as chronic airway inflammation and infection with abnormal airway dilatation; however, there are little studies ...

Assessment of the role of fractional exhaled nitric oxide as a predictor of airway eosinophilia and corticosteroid responsiveness in patients with chronic cough

The Egyptian Journal of Bronchology, 2020
Background Fractional exhaled nitric oxide (FeNO) can be used as a rapid indicator of eosinophilic airway inflammation and steroid responsiveness in patients with bronchial asthma, but this role in chronic cough is still questionable.

Association of wheezing phenotypes with fractional exhaled nitric oxide in children [PDF]

Korean Journal of Pediatrics, 2014
Asthma comprises a heterogeneous group of disorders characterized by airway inflammation, airway obstruction, and airway hyperresponsiveness (AHR). Airway inflammation, which induces AHR and recurrence of asthma, is the main pathophysiology of asthma ...

The Role of Breastfeeding on Respiratory Outcomes Later in Childhood

Frontiers in Pediatrics, 2022
BackgroundBreastfeeding is associated with a lower risk of wheezing in early childhood, but its effect later in childhood remains unclear. We investigated the association of breastfeeding and respiratory outcomes in children aged 11 years.Materials and ...

Effects of age, gender, and environmental exposures on exhaled nitric oxide level in healthy 12 to 18 years Qatari children

Annals of Thoracic Medicine, 2012
Context: Fractional exhaled nitric oxide (FENO) is a useful noninvasive diagnostic tool for asthma and some other pediatric respiratory diseases. Factors affecting FENO level are variable in different populations and studies.

Hair analysis of formoterol as a novel tool to assess long‐term inhalation medication adherence: Data from the TRICOLON trial

British Journal of Clinical Pharmacology, EarlyView.
Aim The aim of this paper is to examine inhaled formoterol concentrations in hair and assess the potential of hair analysis as a tool for measuring long‐term adherence, by validation with objective data from digital inhalers. Methods Hair samples and digital inhaler data were collected from patients with COPD in 10 hospitals in the Netherlands as part ...
