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)
