[] Just as asthma is no longer grouped with COPD, the current definition of COPD put forth by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) also no longer distinguishes between emphysema and chronic bronchitis. 2,3 These auto-antibodies result in immune complex formation and complement mediated lung injury. During an episode of acute bronchitis, the cells of the bronchial-lining tissue are irritated and the mucous membrane becomes hyperemic and edematous, diminishing bronchial mucociliary function. Emphysema and chronic bronchitis are airflow-limited states contained within the disease state known as chronic obstructive pulmonary disease (COPD). During the last decade, the hospitalisation rate for men aged 45 years and over declined from 864 per 100,000 population in 2008–09 to 792 per 100,000 population in 2017–18.
