Developmental phase
Assessment
Primary outcomes
Primary endpoint is to investigate the correlation frequency of IL-38 positive cells per macrophage or monocytes in induced sputum and airway inflammation, hyperresponsiveness on methacholine, and asthmatic response after allergen challenge in atopic mild adult asthmatics.
Key secondary outcomes
Secondary endpoint is investigate the correlation frequency of IL-38 positive cells per macrophage or monocytes in induced sputum and peripheral blood in atopic mild adult asthmatics. We investigate whether frequency of IL-38 positive cells per macrophage or monocytes induced sputum and peripheral blood will be able to usefulness to evaluate the pathogenesis and severity of asthma as a biomarker.
