Usefulness of Exhaled Breath Condensate for Evaluation of Markers of Airway Inflammation in Children With Asthma
Summary
Exhaled breath condensate (EBC) has emerged as a novel noninvasive technique for assessment of airway inflammation, and it provides information on airway lining fluid composition. Traditionally, such assessment relies on invasive diagnostic tools such as bronchial biopsy and bronchoalveolar lavage (BAL) to obtain specimens from the airway but it is very uncomfortable procedure especially for young patients. The aim of this study is to evaluate the effect of allergic disease, disease monitoring and exposure to tobacco smoke on airway inflammation measured by markers in exhaled breath condensate (EBC) in children with asthma allergic to house dust mite. Also, we aim to assess correlations between cytokine concentrations in EBC and clinical characteristic of the patients with exercise-induced bronchoconstriction as another phenotype of asthma.
