Future Perspectives in the Diagnosis and Treatment of Liver Disease Associated with Alpha-1 Antitrypsin Deficiency

open access: yesGE: Portuguese Journal of Gastroenterology, 2023
Alpha-1 antitrypsin deficiency (AATD) is one of the most common genetic diseases and is caused by mutations in the SERPINA1 gene. The homozygous Pi*Z variant is responsible for the majority of the classic severe form of alpha-1 antitrypsin deficiency ...

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.

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 ...

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

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

open access: yesPulmonology
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 ...
