Summary
The distal lung contributes to asthmatic airway remodeling which is observed from early onset of the disease. Cysteinyl leukotrienes (CysLT) play important role in the pathogenesis of airway remodeling and antileukotrienes work to exert a certain degree of anti-inflammatory effect. The cysteinyl leukotriene antagonist Montelukast has been in vivo shown to significantly inhibit ovalbumin induced airway smooth muscle hyperplasia and subepithelial fibrosis in sensitized mice. This study aims to evaluate if Montelukast could reverse airway remodeling in asthma patients by a non-invasive approach-HRCT.
