New Web site explains how AAT differs from COPD


A new Web site has come on-line at to raise awareness of alpha1-antitrypsin deficiency (AAT), which can be confused with chronic obstructive pulmonary disease (COPD). AAT is a genetic lung disease characterized by low AAT protein in the blood; the protein protects the lungs from damaging enzymes released by white blood cells. The American Lung Association estimates that 100,000 Americans have AAT, but 95% of cases are undiagnosed. The Web site is hosted by Baxter, maker of Aralast for the treatment of AAT.
