This ongoing liver injury leads to cirrhosis in a significant number of adults with AAT deficiency.', 'detailedDescription': 'Our overarching hypothesis is that liver disease in adults with AAT deficiency is the result of the accumulation of the abnormally folded protein within the endoplasmic reticulum of the hepatocyte. In some individuals, the intrinsic cellular mechanisms of the hepatocyte are sufficient to clear adequate amounts of the abnormally folded protein such that liver disease does not occur. In AAT deficient individuals who develop liver disease, environmental and other genetic factors stress the hepatocyte, and the normal cellular mechanisms that maintain homeostasis are disrupted, leading to liver disease.\n\nFor this proposal, our hypothesis is that the prevalence of liver disease in adults with AAT is higher than previously reported because liver injury and fibrosis is not accurately detected by available routine liver testing. Testing this hypothesis will require an initial evaluation for liver disease with liver function testing and imaging, and then histologic confirmation by liver biopsy.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Pulmonary clinic, hepatology clinic, and the Alpha-1 Antitrypsin Tissue and Data Bank.', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Alpha-1 Antitrypsin deficiency confirmed to be PI\\*ZZ by both genotype or another identified rare allele;\n* Age range from 18-70;\n* Willingness to consent to liver biopsy;\n* Ability to travel to UF as necessary by protocol; and\n* Platelet count greater than or equal to 50,000/mm3 and an INR less than or equal to 1.5.\n\nExclusion Criteria:\n\n* Hemophilia, anticoagulant therapy that cannot be interrupted briefly, malignancy, or any other condition that would compromise the safety of a liver biopsy;\n* Any known pre-existing medical condition that might interfere with the patient's participation in and completion of the study or any condition, which in the opinion of the investigator would make the patient unsuitable for enrollment;\n* Active substance abuse including, but not limited to, alcohol, intravenous or, inhaled drugs;\n* History of adverse reactions or allergy to the local anesthetic, sedative, or pre-medication used for the percutaneous liver biopsy;\n* Poor venous access making the subject unable to complete the required laboratory testing schedule; and\n* Females who are pregnant or lactating at time of enrollment.
