The undiagnosed disease burden associated with alpha-1 antitrypsin deficiency genotypes

open access: yesEuropean Respiratory Journal, 2020
Alpha-1 antitrypsin deficiency (AATD), mainly due to the PI*ZZ genotype in SERPINA1, is one of the most common inherited diseases. Since it is associated with a high disease burden and partially prevented by smoking cessation, identification of PI*ZZ ...

PROINFLAMMATORY CYTOKINE PROFILE IN PATIENTS WITH DIFFERENT ALPHA-1-ANTITRYPSIN PHENOTYPES

open access: yesМедицинская иммунология, 2016
Alpha-1-antitrypsin (A1AT) exerts a wide spectrum of protective effects, being focused on reduction of secondary injury in inflammation. Moreover, A1AT inhibits some serine proteases, and down-regulates production of proinflammatory cytokines.

Causal and Synthetic Associations of Variants in the SERPINA Gene Cluster with Alpha1-antitrypsin Serum Levels [PDF]

open access: yes, 2013
Several infrequent genetic polymorphisms in the SERPINA1 gene are known to substantially reduce concentration of alpha1-antitrypsin (AAT) in the blood.

A Review of Alpha-1 Antitrypsin Deficiency

open access: yesSeminars in Respiratory and Critical Care Medicine, 2005
Alpha-1 antitrypsin (AAT) is a protein that prevents enzymes such as elastin from degrading normal host tissue. Individuals who are deficient in AAT (those with levels < 11 micromol/L) are at risk for developing such clinical manifestations as emphysema, cirrhosis, panniculitis, and anticytoplasmic neutrophilic antibody (C-ANCA)-positive vasculitis ...

Alpha 1-antitrypsin deficiency in patients with chronic obstructive pulmonary disease patients: is systematic screening necessary?

open access: yesBMC Research Notes, 2019
Objective Alpha-1-antitrypsin deficiency is a relatively prevalent, but under-diagnosed, genetic disease. The objective of this study was to assess whether the systematic screening for alpha-1-antitrypsin deficiency in all patients with chronic ...

Alpha-1-Antitrypsin Deficiency

open access: yesSeminars in Liver Disease, 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.

Alpha1 antitrypsin deficiency due to an homozygous PI* Null Q0Cairo mutation: Early onset of pulmonary manifestations and variability of clinical expression

open access: yesRespiratory Medicine Case Reports, 2018
Alpha-1 antitrypsin deficiency is an autosomal, codominant disorder caused by mutations of the SERPINA1 gene. This genetic disorder is mainly associated with development of pulmonary emphysema and/or chronic liver disease and cirrhosis.Here we report a ...

Non-invasive testing for liver pathology in alpha-1 antitrypsin deficiency

open access: yesBMJ Open Respiratory Research, 2020
Background Many patients with alpha-1 antitrypsin deficiency (A1ATD) receive care in respiratory clinics without access to specialist hepatology expertise. Liver disease can develop asymptomatically, and non-invasive markers of fibrosis may help identify
