In clinical trials, the use of inhaled corticosteroids is associated with an increased risk of pneumonia in people with COPD, but whether the same is true for people with asthma is not known. ⋯ People with asthma receiving inhaled corticosteroids are at an increased risk of pneumonia or lower respiratory infection, with those receiving higher doses being at greater risk. Pneumonia should be considered as a possible side effect of inhaled corticosteroids, and the lowest possible dose of inhaled corticosteroids should be used in the management of asthma.

The first five cases of α1-antitrypsin deficiency were originally published in 1963. This changed our whole concept about the pathophysiology of emphysema, including the role of inflammation and, in particular, the role of proteolytic enzymes. However, the observation also had a significant 50-year impact on many aspects of protein biochemistry, genetics, cell biology, and disease concepts outside the lung as well as the study of COPD in general.
