ALPHA-1 ANTITRYPSIN DEFICIENCY
Signs & Symptoms: Alpha-1 Antitrypsin Deficiency
Alpha-1 antitrypsin deficiency is most often associated with lung disease. It is also associated with liver disease and some rare conditions.
Alpha-1 lung disease tends to show up when people are in their 20s or 30s, but symptoms may develop at any age. Many people who have Alpha-1 never experience symptoms or significant lung impairment.
Signs and symptoms of Alpha-1 lung disease include:
- Shortness of breath, with or without exercise
- Wheezing, excess phlegm (mucus), or a persistent cough
- Fatigue
- Recurrent lung or sinus infections
- Emphysema or chronic obstructive pulmonary disease (COPD)
- Asthma with airflow obstruction that is not completely reversible after treatment with bronchodilators
- Abnormal lung function tests with or without known risk factors (like smoking or environmental exposures)
- Bronchiectasis, a chronic inflammation of the lungs, without a known cause
Liver disease affects a small percentage of people with Alpha-1. Other factors — both genetic and environmental — often play a role in whether someone develops liver disease. Although liver complications can occur at any age, the risk increases over time. Men have a greater chance of developing liver disease than women. Current research shows that people with Alpha-1-related liver disease rarely also have lung disease, and vice versa.
Signs and symptoms of Alpha-1 liver disease include:
- Elevated liver enzymes (determined by lab testing)
- Jaundice – a yellow or bronze color of the skin or eyes
- Cirrhosis – hardening of the liver due to build-up of scar tissue
- Hepatocellular carcinoma – a type of liver cancer
- Unexplained liver disease in newborns, children, adults, and especially the elderly
Other, less common conditions associated with Alpha-1 are:
- Necrotizing panniculitis – a treatable skin condition in which painful, red lumps appear on the thighs that can develop ulcerations and eventually death of skin cells (or "necrotizing")
- Vasculitis – a inflammation of blood vessels or lymph nodes, specifically called anti-proteinase 3-positive vasculitis (or C-ANCA)
