Treatment
In the United States, Canada, and several European countries, lung-affected A1AD patients may receive intravenous infusions of alpha-1 antitrypsin, derived from donated human plasma. This augmentation therapy is thought to arrest the course of the disease and halt any further damage to the lungs. Long-term studies of the effectiveness of A1AT replacement therapy are not available. It is currently recommended that patients begin augmentation therapy only after the onset of emphysema symptoms.
Augmentation therapy is not appropriate for liver-affected patients; treatment of A1AD-related liver damage focuses on alleviating the symptoms of the disease. In severe cases, liver transplantation may be necessary.
As α1-antitrypsin is an acute phase reactant, its transcription is markedly increased during inflammation elsewhere in response to increased interleukin-1 and 6 and TNFα production.
Treatments currently being studied include recombinant and inhaled forms of A1AT. Other experimental therapies are aimed at the prevention of polymer formation in the liver.

Famous quotes containing the word treatment:
“Ambivalence reaches the level of schizophrenia in our treatment of violence among the young. Parents do not encourage violence, but neither do they take up arms against the industries which encourage it. Parents hide their eyes from the books and comics, slasher films, videos and lyrics which form the texture of an adolescent culture. While all successful societies have inhibited instinct, ours encourages it. Or at least we profess ourselves powerless to interfere with it.”
—C. John Sommerville (20th century)
“To me, nothing can be more important than giving children books, It’s better to be giving books to children than drug treatment to them when they’re 15 years old. Did it ever occur to anyone that if you put nice libraries in public schools you wouldn’t have to put them in prisons?”
—Fran Lebowitz (20th century)
“I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrongdoing. Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly, I will not give to a woman a pessary to cause abortion. I will keep pure and holy both my life and my art.”
—Hippocrates (c. 460–c. 370 B.C.)
