Stoller Y1 - 2016/07/01 UR - http://www.ccjm.org/content/83/7/507.abstract N2 - Alpha-1 antitrypsin deficiency is common but underrecognized.

The weight of available evidence supports the biochemical and clinical efficacy of intravenous augmentation therapy. Promising new therapies are being investigated. ER -
