Alpha-1 Antitrypsin Deficiency (AATD)

Studies Actively Enrolling

The Role of Diseases in Macrophage Function

Alpha-1-antitrypsin (AAT) deficiency and Cystic Fibrosis (CF) share a similar pathway during the folding of the affected protein. In both conditions the mutation leading to the disease causes a misfolding of the affected protein causing several biological effects that we intend to explore. Investigators will collect peripheral blood monocytes, pulmonary function tests and serum C-reactive protein levels from PIMM, PIMZ, PISZ, PIZZ and other rare allele individuals, along with healthy controls and individuals with cystic fibrosis (CF)specifically, homozygous for Delta F508 CFRT mutation, measure the differences in the gene expression of AAT and various other genes in these monocytes at various stages of maturation to macrophages, evaluate the differences in the macrophage function, and determine the mechanisms contributing to these differences.

Liver Fibrosis in Alpha-1 Antitrypsin Deficiency (AATD)

We hypothesize that individuals with Alpha-1 Antitrypsin (AAT) deficiency have ongoing liver injury which is not detected by the usual blood tests used to look at liver function. This ongoing liver injury leads to cirrhosis in a significant number of adults with AAT deficiency. Testing this hypothesis will require an initial evaluation for liver disease with liver function testing and imaging, and then histologic confirmation by liver biopsy.

Alpha-1 Antitrypsin Deficiency: Understanding and Identifying. Does a Short Video Improve Physician Understanding and Increase Testing?

Almost 13 million adults in the United States have Chronic Obstructive Pulmonary Disease (COPD). Alpha-1 Antitrypsin Disease (AATD) is an inherited cause of COPD. COPD associated AATD is taught to medical students. Yet, fewer than 10% of Americans with AATD have been diagnosed and the average interval between onset of symptoms and diagnosis is over 8 years. Previous research has demonstrated a low level of knowledge about AATD among physicians, while research with medical students demonstrates that core basic clinical knowledge is lost during clinical years.
