Diabetic retinopathy: could the alpha-1 antitrypsin be a therapeutic option? [PDF]

, 2014
Diabetic retinopathy is one of the most important causes of blindness. The underlying mechanisms of this disease include inflammatory changes and remodeling processes of the extracellular-matrix (ECM) leading to pericyte and vascular endothelial cell ...

Alpha-1 Antitrypsin Deficiency Liver Disease [PDF]

Clinics in Liver Disease, 2021
Liver disease in homozygous ZZ alpha-1 antitrypsin (AAT) deficiency occurs due to the accumulation of large quantities of AAT mutant Z protein polymers in the liver. The mutant Z protein folds improperly during biogenesis and is retained within the hepatocytes rather than appropriately secreted.

Structural characterization and conformational dynamics of alpha-1 antitrypsin pathogenic variants causing alpha-1-antitrypsin deficiency

Frontiers in Molecular Biosciences, 2022
Background: Alpha-1 antitrypsin deficiency (A1ATD) is a progressive lung disease caused by inherited pathogenic variants in the SERPINA1 gene. However, their actual role in maintenance of structural and functional characteristics of the corresponding α-1

Testing for alpha-1 antitrypsin in COPD in outpatient respiratory clinics in Spain: A multilevel, cross-sectional analysis of the EPOCONSUL study [PDF]

, 2018
Background Alpha-1 antitrypsin deficiency (AATD) is the most common hereditary disorder in adults, but is under-recognized. In Spain, the number of patients diagnosed with AATD is much lower than expected according to epidemiologic studies.

alpha 1-antitrypsin deficiency.

Monaldi archives for chest disease = Archivio Monaldi per le malattie del torace, 1998
Homozygous PIZZ alpha 1-antitrypsin deficiency, which has an incident of 1 in 1600 to 1 in 2000 live births, is the most common genetic cause of liver disease in children. It is also associated with chronic liver disease and hepatocellular carcinoma in adults. It is a well-known cause of pulmonary emphysema.

Elucidating the mechanism of action of alpha-1-antitrypsin using retinal pigment epithelium cells exposed to high glucose. Potential use in diabetic retinopathy.

PLoS ONE, 2020
BACKGROUND:Alpha-1-antitrypsin is a protein involved in avoidance of different processes that are seen in diabetic retinopathy pathogenesis. These processes include apoptosis, extracellular matrix remodeling and damage of vessel walls and capillaries ...

Idiopathic Hemochromotosis and Alpha‐1‐Antitrypsin Deficiency: Coexistence in a Family with Progressive Liver Disease in the Proband [PDF]

, 1983
A patient with coexistent hemochromatosis and alpha‐1‐antitrypsin deficiency which led to cirrhosis and death despite adequate therapy for hemochromatosis is reported. Evaluation of the family revealed first degree relatives with iron overload and others

Augmentation therapy with human alpha-1-proteinase inhibitor reduces exacerbations in patient with bronchiectasis and alpha-1-antitrypsin deficiency

Respiratory Medicine Case Reports, 2022
Alpha-1-antitrypsin deficiency (AATD) is a rare cause of noncystic fibrosis (CF) bronchiectasis. The benefits of augmentation therapy in patients with chronic obstructive pulmonary disease (COPD) and pulmonary emphysema are well established.

Clinical features in patients with severe Alpha-1 antitrypsin deficiency due to rare genotypes

Pulmonology
Alpha-1 Antitrypsin Deficiency (AATD) is a co-dominant condition associated with an increased risk of lung and liver disease. Since it is commonly thought that 95% of severe cases of AATD have PI*ZZ genotype, most studies about AATD have been focused on ...
