Asthma is a chronic inflammatory disease which is characterized by airway hyperresponsiveness with reversible bronchial obstruction, spontaneously or with treatment. Its development depends on interactions between external factors and genetic predisposition to atopy and bronchial hyperresponsiveness. Exacerbations are caused by allergens (antigens from dust mites, pets, cockroach and molds), viral infections and other irritants (tobacco, weather changes and medications). Bronchial inflammation is the major feature in asthma pathogenesis and results from complex interactions between inflammatory cells, structural bronchial cells, cytokines and inflammatory mediators. Some clinical comorbidities can be associated with asthma, contributing to its severity, such as rhinosinusitis, gastroesophageal reflux and broncopulmonary allergic fungal diseases.Downloads
