title: Airway remodelling in cough-variant asthma.
abstract: Subepithelial-layer thickening, a pathological feature of airway remodelling, is present in cough-variant asthma. In bronchial biopsy samples we found mean subepithelial-layer thickness was 7.1 (SE 0.4) microm in patients with cough-variant asthma, 8.6 (0.4) microm in patients with classic asthma with wheezing, and 5.0 (0.2) microm in healthy controls. Thickness was significantly higher in patients with asthma than in controls, and was significantly greater in those with classic asthma than in those with cough-variant asthma. Early anti-inflammatory treatment might, therefore, be beneficial in cough-variant asthma, as recommended in classic asthma.
