Alpha-1 antitrypsin deficiency (A1AD) is an hereditary disorder characterized by low levels of a protein called alpha-1 antitrypsin (A1AT) which is found in the blood. This deficiency may predispose an individual to several illnesses and most commonly manifests as chronic obstructive pulmonary disease (including bronchiectasis) and liver disease (especially cirrhosis and hepatoma), or more rarely, as a skin condition called panniculitis. A1AD is also more frequent among individuals with Wegener's granulomatosis. A deficiency of A1AT allows substances that break down proteins (so-called proteolytic enzymes) to attack various tissues of the body. The attack results in destructive changes in the lungs (emphysema) and may also affect the liver and skin. Alpha-1 antitrypsin is ordinarily released by specialized, granules within a type of white blood cells (called neutrophils or polymorphonuclear leukocytes) in response to infection or inflammation. Deficiency of alpha-1 antitrypsin results in unbalanced (i.e., relatively unopposed) rapid breakdown of proteins (protease activity), especially in the supporting elastic structures of the lungs. Over years, this destruction leads to progressive emphysema and is accelerated by smoking, some occupational exposures, and likely by other genetic modifiers of this risk which remain incompletely understood.
