Original Question

COPD is an inflammatory condition involving the airways, lung parenchyma, and pulmonary vasculature. The process is thought to involve oxidative stress and protease-antiprotease imbalances. Emphysema describes one of the structural changes seen in COPD where there is destruction of the alveolar air sacs (gas-exchanging surfaces of the lungs) leading to obstructive physiology. In emphysema, an irritant (e.g., smoking) causes an inflammatory response. Neutrophils and macrophages are recruited and release multiple inflammatory mediators. Oxidants and excess proteases leading to the destruction of the air sacs. The protease-mediated destruction of elastin leads to a loss of elastic recoil and results in airway collapse during exhalation. [1][3] Alpha-1 antitrypsin deficiency is a rare cause of emphysema which involves a lack of antiproteases and the imbalance leaves the lung parenchyma at risk for protease-mediated damage. AATD is caused by misfolding of the mutated protein which can accumulate in the liver. AATD should be suspected in COPD patients who present with liver damage. As opposed to smoking-related emphysema, AATD primarily involves the lower lobes. [1]
