Question

Which type of emphysema is commonly seen in people with α1-antitrypsin deficiency?

A) Centriacinar emphysema
B) Panacinar emphysema
C) Paraseptal emphysema
D) Irregular emphysema

Answer 1

The type of emphysema commonly seen in people with α1-antitrypsin deficiency is Panacinar emphysema.

Step-by-step explanation:

The type of emphysema commonly seen in people with α1-antitrypsin deficiency is Panacinar emphysema. α1-antitrypsin is an inhibitor of neutrophil elastase, which normally prevents the destruction of elastin in the alveoli of the lungs. In individuals with α1-antitrypsin deficiency, the lack of this inhibitor allows elastase to break down elastin, leading to the development of emphysema.
