Alpha-1 antitrypsin deficiency (Alpha-1) is a hereditary genetic disorder which may lead to the development of lung and/or liver disease. It is the most common genetic cause of liver disease in children. Adults can also be affected by Alpha-1 and may develop lung conditions such as emphysema as well as liver problems. Fortunately, many persons diagnosed with Alpha-1 never develop any of the associated diseases.
In newborns, the typical symptoms of Alpha-1 are jaundice, swelling of the abdomen, and poor feeding. Alpha-1 may also appear in late childhood or adulthood and be detected because of fatigue, poor appetite, swelling of the abdomen and legs or abnormal liver tests.
Alpha-1 antitrypsin is a protein made in the liver which plays an important role in preventing the breakdown of enzymes in various organs. Individuals with Alpha-1 have a genetic disorder that prevents their body from creating enough of this protein. This trait must be inherited from both parents (who are, by definition, carriers) in order to cause the disorder.
The diagnosis of Alpha-1 is made by blood tests showing the low levels of alpha-1 antitrypsin and abnormal liver tests. Other tests such as ultrasound imaging or tests using specialized X-ray techniques may be necessary. A liver biopsy may be performed to check for damage to the liver.
Currently, there is no cure for Alpha-1. Treatment is designed to maintain normal nutrition, to provide the liver and the body with essential nutrients, and to identify complications early in order to treat them better. Multiple vitamins and vitamins E, D, and K are often given. Certain abnormalities can be treated or controlled. Jaundice, severe itching, and fluid retention can all be dealt with through medication.
Worldwide, approximately 1 in 2,500 individuals has Alpha-1 Antitrypsin Deficiency. This disorder is found in all ethnic groups; however, it occurs most frequently in whites of European ancestry.
Clinical trials are research studies that test how well new medical approaches work in people. Before an experimental treatment can be tested on human subjects in a clinical trial, it must have shown benefit in laboratory testing or animal research studies. The most promising treatments are then moved into clinical trials, with the goal of identifying new ways to safely and effectively prevent, screen for, diagnose, or treat a disease.
Speak with your doctor about the ongoing progress and results of these trials to get the most up-to-date information on new treatments. Participating in a clinical trial is a great way to contribute to curing, preventing and treating liver disease and its complications.
