Smoking: it's still a big problem in children with asthma
Journal Title: Jornal de Pediatria - Year 2019, Vol 95, Issue 5
Abstract
Smoking is an independent risk factor for the development of asthma symptoms,1 loss of lung function,2 and asthma exacerbations.3 The mechanisms of smoking-related lung disease can include increased small-airway inflammation with neutrophils and macrophages, airway hyper-responsiveness, and airflow obstruction.4,5 Additionally, patients with asthma who smoke have a reduced response to inhaled corticosteroids.6 The effect of smoking on asthmatic lungs also appears to increase the development of features of chronic obstructive pulmonary disease (COPD), and there is an increasing body of knowledge about an asthma-COPD overlap syndrome. Most adults who smoke regularly started the habit as adolescents. The Global Initiative for Asthma (GINA) guidelines stresses the critical importance of identifying modifiable risk factors for exacerbations, such as smoking.7 It also asks healthcare providers to encourage smokers to quit at every visit and provide access to counseling and resources.
