Abstract
Purpose of review: Chronic bronchitis is a phenotype of chronic obstructive pulmonary disease (COPD), characterized by chronic cough and sputum production, associated with an increased rate of COPD exacerbations and hospital admissions, a more rapid decline in lung function and reduced life expectancy. Despite optimal medical therapy, chronic bronchitis remains difficult to treat. Interventional bronchoscopic procedures offer novel therapeutic approaches to this highly symptomatic condition.
Recent findings: A characteristic feature of chronic bronchitis is the presence of an abnormal epithelium with excessive mucus producing cells, parasympathetic overactivity, and airway inflammation. Metered cryospray and bronchial rheoplasty are designed to target this abnormal epithelium to reduce mucus production and inflammation. Targeted lung denervation aims to reduce parasympathetic overactivity, which may drive mucus hypersecretion. Here, we review the available evidence to determine the safety and efficacy across the bronchoscopic interventions.
Summary: Interventional bronchoscopy is a rapidly expanding field and its application in the treatment of chronic bronchitis has been recognized by the Global initiative for chronic Obstructive Lung Disease (GOLD). The outcomes from the latest clinical trials will guide future treatment approaches in patients with difficult to treat chronic bronchitis.
