摘要

Sir, Pulmonary emphysema is the principal clinical characteristic and the most common cause of death inpa-tients with severe alpha-1-antitrypsin deficiency (A1ATD), an autosomal hereditary disease that has also been causally associated with injury to liver and other tissues [1]. AlAT's primary function is to inhibit neutrophil elastase and other serine proteases, although it is believed to possess immunomodulatory and anti-inflammatory roles [2]. Granulomatosis with polyangiitis is a rare type of vascu-litis that principally affects small vessels. Granulomatosis with polyangiitis is strongly associated (80-90%) with the presence of ANCAs, with specificity for neutrophil PR3. The underlying trigger for granulomatosis with polyangiitis is still unknown, although involvement of both environmental and genetic factors has been suggested [3].
