Alpha 1 Antitrypsin Deficiency
What is Alpha 1 Antitrypsin Deficiency?
Alpha 1 is the common name for a genetic condition called Alpha 1 Antitrypsin Deficiency. If you have Alpha 1, your body is unable to produce a protein known as Alpha 1 Antitrypsin, or AAT for short. This protein plays an important role in protecting your lungs from damage due to excessive inflammation. Without this protein present in your blood, your lungs may weaken over time and place you at a higher risk for developing serious diseases, such as early-onset emphysema often misdiagnosed as chronic obstructive pulmonary disease (COPD). An abnormal amount of AAT in the liver can also cause liver disease.

How is Alpha 1 Diagnosed?
Alpha 1 can only be diagnosed by a blood test. If you have a family history of Alpha 1, COPD, emphysema, irreversible asthma, unexplained liver disease, or a skin disorder called necrotizing panniculitis, you should be tested. Alpha 1 is a progressive disease, which means if it is left undiagnosed and untreated, it can get worse and may do more harm to your lungs and body over time.

How Alpha 1 Antitrypsin Works - The Liver/Lung Connection
Alpha 1 Antitrypsin (AAT) is a protein made in your liver. Its main function is to protect your lungs against attack by an enzyme called neutrophil elastase which is usually involved in the inflammation caused by infection and inhaled irritants such as tobacco smoke. With respect to AATD, a low level of AAT in the blood occurs because the AAT is abnormal and cannot be released from the liver at the normal rate. This leads to an accumulation of abnormal AAT in the liver that can cause liver disease and a decrease of AAT in the blood that can lead to lung disease.

Early signs of hypersensitivity reactions to ZEMAIRA include hives, rash, tightness of the chest, unusual breathing difficulty, wheezing, and feeling faint. Immediately discontinue use and consult with physician if such symptoms occur. In clinical studies, the following adverse reactions were reported in at least 5% of subjects receiving ZEMAIRA: headache, sinusitis, upper respiratory infection, bronchitis, fatigue, increased cough, fever, injection-site bleeding, nasal symptoms, sore throat, and swelled blood vessels. |
