Extractions: INTRODUCTION Alpha-1 antitrypsin deficiency (A AD) is a common genetic disorder that primarily affects the lungs and liver and can lead to emphysema and cirrhosis. Laurell and Erikkson first identified the condition in 1963 in Sweden. A AD is shown to be highly prevalent in Caucasians of Northern European descent, especially Scandinavians. A AD occurs in one of every 2,000 live births, yet less than 100,000 Americans are diagnosed with the disease at any given time. A1AD can be difficult to diagnose, especially in adults, and is significantly underrecognized. Age appears to be a factor in the type of manifestations caused by the deficiency, but symptoms may vary greatly from person to person. In infants, A AD is most likely to cause cirrhosis. If no symptoms are exhibited in childhood, emphysema is the most common adult manifestation, with age of onset occurring between 30 and 50 years of age. Between 2-18% of all emphysema patients are Alpha-1 deficient. This disease causes a significant number of emphysema cases. Alpha-1 antitrypsin deficiency accounts for 2 to 3% of COPD patients. Alpha-1 antitrypsin deficiency has been given many names over the years. The following are some well-known synonyms:

Alpha-1 antitrypsin is a protein synthesised in the liver and immediately secreted into the blood where it acts as an antiprotease (protease inhibitor Pi). There are several phenotypes : There are two clinical problems as a result of alpha-1 antitrypsin deficiency : Hepatitis and Cirrhosis the unusual phenotypes of alpha-1 antitrypsin are not released readily from the liver and the unreleased protein then accumulates in the cytoplasm of periportal hepatocytes in the from of hyaline intracellular globules NB all PiZZ people accumulate abnormal protein but only up to 20% develop liver disease neonatal hepatitis with cholestatic jaundice adolescents get attacks of acute hepatitis

Extractions: Alpha-1 antitrypsin deficiency, also known as Alpha-1, is an inherited disorder that causes a significant reduction in the naturally occurring protein alpha-1 antitrypsin (AAT). Reduced levels of AAT result in the body being less able to protect itself from elastase, an enzyme in the white blood cells that normally helps to fight bacteria and that can cause damage to the air sacs in the lungs if not neutralized by AAT. AAT deficiency may predispose an individual to several serious illnesses, most commonly emphysema beginning in the third or fourth decade of life. Less frequently, AAT deficiency can result in liver disease, or a skin condition called panniculitis. Bayer Biological Products (BP) has worked over the past 15 years to provide the only available augmentation therapy for people with this deficiency. Our commitment to this community is demonstrated in our continued support of a number of organizations that serve the Alpha 1 community, and our support of patient identification programs.

A lpha-1 is a genetic disease of the liver, lungs and a skin disease, panniculitis. It results from a lack of the Alpha-1 Antitrypsin (AAT) protein in a person's blood, which protects the lungs from germs, dust, air pollution, cigarette smoke and other inhaled irritants. Without an adequate supply of AAT, substances in the white blood cells can damage the tissues of the body.

What Is The Longterm Outcome Of Alpha-1 After Liver Transplant? Answer Jeff Punch, MD A search on Medline reveals no reports of recurrenceof alpha1 antitrypsin deficiency in the scientific literature. http://www.transweb.org/qa/asktw/answers/answers9509/longtermoutcomeofalpha1.htm
Extractions: A search on Medline reveals no reports of recurrence of alpha-1 antitrypsin deficiency in the scientific literature. If our current understanding of alpha-1 antitrypsin deficiency is correct, it should not be possible for alpha-1 antitrypsin deficiency to recur in the transplnted liver. The new liver has a normal gene that produces alpha-1 antitrypsin. Current areas of research include gene therapy to treat the disease in asymptotic carriers. Alpha 1 antitrypsin deficiency would be an ideal disease to treat with gene therapy. The genetics of alpha 1 antitrypsin deficiency are pretty well worked out, but it is still not possible to predict the rate the disease will progress with absolute the certainty. Bob Merion, MD:

Extractions: A: Alpha 1- antitrypsin is a glycoprotein produced by the liver. Its primary function is to protect the lungs from neutrophil elastase, which is an enzyme that digests the phagocyte cells and bacteria to promote healing. However, it requires alpha-l antitrypsin to prevent it from damaging the lung tissue. Alpha-l- antitrypsin is an acute- phase reactant. Its level increases to 3 or 4 times the normal amount at times of infection, pregnancy or any conditions that cause an increase in neutrophil elastase. Q: What happens where there is deficiency of alpha-l- antitrypsin?

Alpha-1 Antitrypsin Deficiency Alpha1-Antitrypsin Deficiency (A1AD) is one of the most common inherited disordersamong whites. Its primary manifestation is early-onset panacinar emphysema. http://www.spiderspun.net/faqs.htm
Extractions: Alpha-1 Facts The Basics The History The Genetic Path The Symptoms ... The Testing Alpha-1-Antitrypsin Deficiency i s one of the most common inherited disorders among Caucasians. Its primary manifestation is early-onset panacinar emphysema. A minority of patients develops hepatic cirrhosis. Slow progressive dyspnea is the primary symptom, although many patients initially have symptoms of cough, sputum production, or wheezing.(7) Alpha-1-antitrysin deficiency, called A1AD, for short, is a genetic disorder characterized by a marked reduction in serum levels of a naturally occurring protein called Alpha-1-antitrypsin (also known as AAT) that causes emphysema cirrhosis , and/or panniculitus . AAT, produced by the liver, shields the body from damage caused by neutrophil elastase, an enzyme released by a type of white blood cell known as neutrophil. Imagine neutrophil elastase as like being a heavy tile cleaner that you spray on mildew. Under normal conditions, neutrophil elastase helps fight bacteria that cause infection because it destroys it. However, if not neutralized by AAT, neutrophil elastase can slowly damage lung tissue, or related tissues where elasticity is needed. In other words, AAT is like the water-filled sponge that wipes away the cleaner before it destroys the floor. Over time this process can result in emphysema. Therefore, people with A1AD are at risk of developing emphysema (1,2). By following their doctor's advice, people with A1AD can learn how to manage their condition and maintain the best possible health.
Extractions: Mayo Clinic in Rochester Wednesday, January 03, 2001 Risk Greatly Magnified by Cigarette Smoking ROCHESTER MINN. Mayo Clinic scientists have discovered that carriers of a genetic defect previously linked to emphysema have a threefold increased risk of developing a type of sporadic colorectal cancer. Carriers who currently smoke have a 20-fold increased risk. "This study provides important new insight into the controversy surrounding the link between cigarette smoking and colorectal cancer, confirming a strong association in a subgroup of colorectal cancers," says Dr. Ping Yang, Mayo Clinic clinical epidemiologist and principal investigator of the study. The genetic defect, alpha-1 antitrypsin deficiency, presents an inadequate level of the protease inhibitor alpha-1 antitrypsin, which protects the surfaces of multiple organs. Alpha-1 antitrypsin is synthesized primarily in the liver and in a small amount of the gastrourinary systems. In individuals who lack this inhibitor, the protease destroys the membrane system, leaving the colon and rectum vulnerable to colorectal cancer development. The investigators believe that cigarette smoking causes a similar effect, further exacerbating tissue destruction for carriers of alpha-1 antitrypsin deficiency, since smoking is a strong inactivator of the protease inhibitor alpha-1 antitrypsin.

Extractions: Alpha-1-antitrypsin deficiency is an inherited disorder which usually affects the lungs. The information presented here is intended to answer your questions and provide you with a better understanding of this rare condition. What is alpha-1-antitrypsin? Alpha-1-antitrypsin is a protein which is produced by the liver and enters the blood stream. Its main role is to protect the lungs from destruction by other proteins called enzymes. Enzymes are found in all parts of the body and are needed for digestion to ensure that chemical reactions in the body proceed normally. Enzymes are also involved in areas of inflammation and tissue injury where they occur as a result of cell damage. What is alpha-1-antitrypsin deficiency? Alpha-1-antitrypsin deficiency is present when there is less than the normal amount of this protein in the blood. It becomes important only when the concentration in the blood is less than 20% to 30% of what we would normally expect. When this deficiency occurs, the lung is poorly protected from destructive enzymes and loss of lung tissue occurs, leading to a condition called emphysema. Once in every 2500 people in Australia has severe alpha-1-antitrypsin deficiency (levels below 20% of normal). This translates to nearly 7000 Australians with alpha-1-antitrypsin deficiency.

Extractions: Swiss Registry for alpha-1 Antitrypsin Deficiency Several years ago we established a National Registry for alpha-1 antitrypsin deficiency at the Pulmonary Division of the University Hospital of Zurich (http://www.unispital.ch/lungenthorax). The purpose is to collect information on patients with this inherited condition within our country. Data are reported by the patients physicians, provided the patient has given his consent. Our registry comprises about 70 patients, mostly with a Pi ZZ or Pi SZ phenotype. Prof. E.W. Russi, head of the Pulmonary Division is a member of the Task Force AIR, which is a multinational group of experts on alpha 1-antitrypsin deficiency. A working group of the Swiss Pulmonary Society made statements several years ago on intravenous augmentation therapy with the human plasma derived product Prolastinâ. Due to a lack of controlled prospective, randomised clinical trials convincingly showing a positive effect on the progression of pulmonary emphysema, this type of treatment is not covered by health insurance in Switzerland.
