Exhaled nitric oxide levels in non-allergic and allergic mono- or polysensitised children with asthma.
BACKGROUND Increased fractional exhaled NO concentrations (FENO) and blood/tissue eosinophilia are frequently reported in allergic children with mild asthma and are thought to reflect the intensity of the inflammation characterising the disease. The aim of this study was to investigate possible differences in FENO levels or in the intensity of the blood eosinophilia in allergic and non-allergic...
متن کاملExhaled Nitric Oxide is Associated with Allergic Inflammation in Children
Exhaled nitric oxide (eNO) has been proposed as a noninvasive marker of airway inflammation in asthma. In asthmatic patients, exhaled NO levels have been shown to relate with other markers of eosinophilic recruitment, which are detected in blood, sputum, bronchoalveolar lavage fluid and bronchial biopsy samples. The purpose of this study was to assess the possible relationship between eNO and a...
متن کاملEnvironmental Effects on Fractional Exhaled Nitric Oxide in Allergic Children
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 pollutants on FeNO in children. Although t...
متن کاملExhaled breath condensate pH and exhaled nitric oxide in allergic asthma and in cystic fibrosis.
BACKGROUND It has been proposed that the pH of airway lining fluid may regulate the fractional exhaled concentration of nitric oxide (Fe(NO)) in respiratory disease. METHODS Fe(NO), exhaled breath condensate (EBC) pH, and EBC concentrations of nitrite plus nitrate (NO2/NO3) were compared in 12 subjects with stable asthma, 18 with stable cystic fibrosis (CF), and 15 healthy control subjects. E...
متن کاملImpaired FEF25-75 may predict high exhaled nitric oxide values in children with allergic rhinitis and/or asthma.
Allergic rhinitis and asthma are closely associated. Inflammation is a common pathological characteristic shared by both disorders. The measure of the fractional concentration of exhaled nitric oxide (FeNO) may be considered a surrogate marker for airway inflammation. Forced expiratory flow between 25 and 75 percent of vital capacity (FEF25-75) has been previously demonstrated to be able to pre...
