Alpha-Antitrypsin deficiency is a medical condition, in which a hereditary deficiency of alpha-antitrypsin can result in liver and lung disease. Alpha-antitrypsin enzyme is produced by the liver and is present in saliva, tears, and cerebrospinal fluids. The enzyme alpha-antitypsin inhibits the action of other different enzymes, which break down protein. A deficiency of alpha-antitrypsin is allowing the other enzymes to injure lung tissue. The lack in blood represents a liver failure to secrete the enzyme. Its retention inside the cells of liver can result in damage, cirrhosis, and scarring (fibrosis). About 25% of children with lack of alfa-antitrypsin are progressing cirrhosis and portal hypertension and are dying by age 12. Up to 25% dye before age 20 and another 25% have only mild to moderate defects of the liver, and are living into adulthood. The rest of the 25% have no signs of developed disease – a lack of alpha-antitrypsin is not common in adults and, even if found can not result in cirrhosis. In most cases, adults with alpha-antitrypsin disorder progress emphysema – the disease of the lungs, that causes shortness of breath increase. Development of liver cancer may happen as well. The treatment of alpha-antitrypsin deficiency includes replacement therapy using synthetic alpha-antitrypsin enzyme and this method shows some promise, but the only successful treatment is liver transplantation. Damage of the liver usually isn’t recurring in the liver that is transplanted, which produces alpha,-antitrypsin. Cure in adults is directed at the lung disease. A very essential treatment prevents infections, and gets the individual who smokes or stops smoking.
