WebNov 30, 2016 · Airway hyperresponsiveness and bronchial reversibility. High degree of airway hyperresponsiveness in response to such stimuli as methacholine is usually … WebA small airway BDR was seen for most tests in asthma and COPD, including oscillometry (R5-20, reactance (X5), area of reactance (AX) and resonant frequency (Fres)) and Maximal Mid Expiratory Flow. Conclusion: There is a measurable BDR in the small airways. However, with no consensus on how to assess BDR, studies were heterogeneous.
WebBackground: Asthma is a chronic inflammatory disease of the airways common in children. Soluble advanced glycation end-product receptor (sRAGE) is a blood biomarker of lung damage and inflammation. We sought to determine whether it could also be a biomarker in childhood asthma. Methods: We conducted a prospective, observational, analytical study … WebOur principal objective was to determine the percentage of patients with COPD (n=62) who were significant responders to the reversibility test according to the 5 recommendations. …
WebJun 3, 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. In asthma, FENO50 increases with bronchodilation and decreases with bronchoconstriction, the latter potentially causing an underestimate of the … WebRespiratory parameters were variable as per age, height, and BMI of the patients. There was a general trend of higher resistance in younger children. The total airway resistance (R 5 ), R 5 –R 19, X 5, and Fres in children under 6 years were 9.28 ± 2.38, 2.01 ± 1.40, −3.56 ± 1.44, and 17.14 ± 2.66 in our study.
