What are the symptoms of alpha-1 antitrypsin deficiency (AATD)? AATD can present as lung disease in adults and can be associated with liver disease in a small portion of affected children. In affected adults, the first symptoms of AATD are shortness of breath with mild activity, reduced ability to exercise and wheezing. These symptoms usually appear between the ages of 20 and 40. Other signs and symptoms can include repeated respiratory infections, fatigue, rapid heartbeat upon standing, vision problems and unintentional weight loss. Individuals with AATD, who have advanced lung disease, have emphysema in which the small air sacs (alveoli) in the lungs are damaged. Symptoms of emphysema include difficulty breathing, a hacking cough and a barrel-shaped chest. Smoking or exposure to tobacco smoke increases the appearance of symptoms and damage to the lungs. Other common diagnoses include COPD (chronic obstructive pulmonary disease), asthma, chronic bronchitis and bronchiectasis - a chronic inflammatory or degenerative condition of one or more bronchi or bronchioles. Liver disease, called cirrhosis of the liver, is another symptom of AATD. It can be present in some affected children, about 10 percent, and has also been reported in 15 percent of adults with AATD. In its late stages signs and symptoms of liver disease can include a swollen abdomen, coughing up blood, swollen feet or legs, and yellowing of the skin and the whites of the eyes (jaundice). Rarely, AATD can cause a skin condition known as panniculitis, which is characterized by hardened skin with painful lumps or patches. Panniculitis varies in severity and can occur at any age.(1)
