Is there a relationship between abdominal aortic aneurysms and alpha1-antitrypsin deficiency (PiZ)? (1/411)

OBJECTIVE: To determine if the frequency of alpha 1AT deficiency (PiZ) is increased in patients with abdominal aortic aneurysm (AAA), and, to investigate whether aneurysmal stiffness and other clinical characteristics differ in AAA patients with and without alpha 1AT deficiency. METHODS: We identified alpha 1AT-deficient individuals by a monoclonal-antibody ELISA technique, in 102 consecutive patients with AAA. Positive ELISA samples were further phenotyped by isoelectric focusing to differentiate between the heterozygosity (PiZ) and homozygosity (PiZZ) state. Aneurysmal diameter and stiffness was measured using echotracking sonography and blood pressure measurements. RESULTS: The frequency of heterozygous alpha 1AT deficiency (PiZ) in patients with AAA was similar to that in the general population (6.8% and 4.7%, respectively, p > 0.3). The frequency of popliteal and femoral aneurysm was similar in male PiZ-carriers and non-carriers with AAA, as were age at diagnosis of AAA, aneurysmal diameter, aneurysmal stiffness, and presence of factors that may be associated with AAA (i.e. smoking, hypertension, diabetes mellitus, and family history of AAA). Occurrence of ischaemic heart disease was more frequent in male non-PiZ-carriers than in male PiZ-carriers with AAA (p = 0.03). CONCLUSIONS: The frequency of alpha 1AT deficiency (PiZ) was not increased in our series of patients with AAA and patients in whom the two disorders coexisted did not appear to have different clinical characteristics except for the lower occurrence of ischaemic heart disease among the PiZ-carriers.  (+info)

Decline in FEV1 related to smoking status in individuals with severe alpha1-antitrypsin deficiency (PiZZ). (2/411)

Severe alpha1-antitrypsin (AAT) deficiency predisposes to emphysema development. Highly variable rates of decline in lung function are reported in PiZZ individuals. The annual decline in forced expiratory volume in one second (FEV1; delta FEV1) was analysed in relation to smoking status in a cohort of 608 adult PiZZ individuals included in the Swedish national AAT deficiency register. Delta FEV1 was analysed in 211 never-smokers, in 351 exsmokers, and in 46 current smokers after performing at least two spirometries during a follow-up time of 1 yr or longer (median 5.5 yrs, range 1-31). The adjusted mean delta FEV1 in never-smokers was 47 mL x yr(-1) (95% confidence interval (CI) 41-53 mL x yr(-1)), 41 mL x yr(-1) (95% CI 36-48 mL x yr(-1)) in exsmokers, and 70 mL x yr(-1) (95% CI 58-82 mL x yr(-1)) in current smokers. A dose-response relationship was found between cigarette consumption and delta FEV1 in current smokers and exsmokers. In never-smokers, a greater delta FEV1 was found after 50 yrs of age than before. No sex differences were found in delta FEV1. In conclusion, among PiZZ individuals, the change in forced expiratory volume in one second is essentially the same in never-smokers and exsmokers. Smoking is associated with a dose-dependent increase in the change in forced expiratory volume in one second.  (+info)

Genes, oxidative stress, and the risk of chronic obstructive pulmonary disease. (3/411)

BACKGROUND: The first-pass metabolism of foreign compounds in the lung is an important protective mechanism against oxidative stress. We investigated whether polymorphisms in the gene for microsomal epoxide hydrolase (mEPHX), an enzyme involved in this protective process, had any bearing on individual susceptibility to the development of chronic obstructive pulmonary disease (COPD) and emphysema. METHODS: We designed PCR-based genotyping assays to detect variant forms of mEPHX that confer slow and fast activity. We used these assays to screen 203 blood-donor controls and groups of patients with asthma (n = 57), lung cancer (n = 50), COPD (n = 68), and emphysema (n = 94), who were attending specialised clinics in Edinburgh, UK. FINDINGS: The proportion of individuals with innate slow mEPHX activity (homozygotes) was significantly higher in both the COPD group and the emphysema group than in the control group (COPD 13 [19%] vs control 13 [6%]; emphysema 21 [22%] vs 13 [6%]). The odds ratios for homozygous slow activity versus all other phenotypes were 4.1 (95% CI 1.8-9.7) for COPD and 5.0 (2.3-10.9) for emphysema. INTERPRETATION: Genetic polymorphisms in xenobiotic enzymes may have a role in individual susceptibility to oxidant-related lung disease. Epoxide derivatives of cigarette-smoke components may be the cause of some of the lung damage characteristics of these diseases.  (+info)

Environmental correlates of impaired lung function in non-smokers with severe alpha 1-antitrypsin deficiency (PiZZ). (4/411)

BACKGROUND: Active smoking is the most important risk factor for pulmonary emphysema in subjects with severe alpha 1-antitrypsin (AAT) deficiency. The aim of this study was to analyse the effects of environmental risk factors other than active smoking on lung function and on respiratory symptoms in non-smoking PiZZ individuals. METHODS: Lifetime exposure to passive smoking, domiciliary use of a kerosene (paraffin) heater or gas cooker, and all occupations since leaving school were reported by 205 non-smoking PiZZ individuals (95 men and 110 women) included in the Swedish AAT deficiency register. Lung function test results and histories of respiratory symptoms (chronic bronchitis, recurrent wheezing, and exertional dyspnoea) were elicited from the AAT register records. RESULTS: After adjustment for age, agricultural employment and domiciliary kerosene heater usage, but not gas cooker usage or passive smoking, were both associated with significantly decreased lung function. Multiple linear regression analysis showed age, sex, kerosene heater usage, and agricultural employment to be independent determinants of lung function impairment. Age and passive smoking for 10 years or more, both at home and at the work place, were associated with the presence of chronic bronchitis. Age and agricultural employment for > or = 10 years were associated with recurrent wheezing and exertional dyspnoea. CONCLUSIONS: Domiciliary kerosene heater usage and an agricultural occupation therefore appear to be environmental factors associated with decreased lung function in non-smoking PiZZ individuals, and passive smoking is associated with an increased frequency of chronic bronchitis, but not with impaired lung function.  (+info)

Heteropolymerization of S, I, and Z alpha1-antitrypsin and liver cirrhosis. (5/411)

The association between Z alpha1-antitrypsin deficiency and juvenile cirrhosis is well-recognized, and there is now convincing evidence that the hepatic inclusions are the result of entangled polymers of mutant Z alpha1-antitrypsin. Four percent of the northern European Caucasian population are heterozygotes for the Z variant, but even more common is S alpha1-antitrypsin, which is found in up to 28% of southern Europeans. The S variant is known to have an increased susceptibility to polymerization, although this is marginal compared with the more conformationally unstable Z variant. There has been speculation that the two may interact to produce cirrhosis, but this has never been demonstrated experimentally. This hypothesis was raised again by the observation reported here of a mixed heterozygote for Z alpha1-antitrypsin and another conformationally unstable variant (I alpha1-antitrypsin; 39Arg-->Cys) identified in a 34-year-old man with cirrhosis related to alpha1-antitrypsin deficiency. The conformational stability of the I variant has been characterized, and we have used fluorescence resonance energy transfer to demonstrate the formation of heteropolymers between S and Z alpha1-antitrypsin. Taken together, these results indicate that not only may mixed variants form heteropolymers, but that this can causally lead to the development of cirrhosis.  (+info)

Alpha-1 antitrypsin deficiency alleles and severe cystic fibrosis lung disease. (6/411)

BACKGROUND: Alpha-1 antitrypsin (alpha 1-AT) is the most abundant proteinase inhibitor within the lung. We have recently reported the surprising observation that cystic fibrosis patients with mild to moderate deficiency of alpha 1-antitrypsin have significantly better pulmonary function than non-deficient patients. This study may have been biased as it did not include the most severely affected patients who have died in childhood or those who have undergone orthotopic lung transplantation. The prevalence of alpha 1-antitrypsin deficiency alleles in this most severely affected group of patients with cystic fibrosis was therefore assessed. METHODS: DNA was obtained from neonatal blood spots from children with cystic fibrosis who had died from pulmonary disease and from formalin fixed lung tissue from transplanted cystic fibrosis patients. The common S and Z deficiency alleles of alpha 1-AT were sought by amplification mutagenesis of the appropriate region of the alpha 1-AT gene followed by restriction enzyme digestion with Xmn I and Taq I, respectively. RESULTS: Seventy-nine patients were identified (seven dead, 72 transplanted). Two patients (2.5%) were heterozygous for the Z allele of alpha 1-AT and four (5.1%) were heterozygous for the S allele. This is not significantly different from the incidence in the normal population of 4% and 8% for the S and Z alleles, respectively. CONCLUSIONS: These data support previous findings that deficiency of alpha 1-AT is not associated with more severe pulmonary disease in cystic fibrosis and may be associated with milder lung disease. Further work is needed to clarify the mechanisms underlying the progressive lung damage in cystic fibrosis.  (+info)

A novel SV40-based vector successfully transduces and expresses an alpha 1-antitrypsin ribozyme in a human hepatoma-derived cell line. (7/411)

Alpha 1-antitrypsin (alpha 1AT) deficiency disease is one of the more common hereditary disorders that affects the liver and lung. The liver disease of alpha 1AT deficiency is generally thought to be caused by the accumulation of an abnormal alpha 1AT protein in hepatocytes, whereas the lung disease is thought to be due to a relative lack of the normal protein in the circulation. Therefore, one possible approach to prevent and treat alpha 1AT disease is to both inhibit the expression of the mutated alpha 1AT gene, and to provide a means of synthesizing the normal protein. To do this, we designed specific hammerhead ribozymes that were capable of cleaving the alpha 1AT mRNA at specific sites, and constructed a modified alpha 1AT cDNA not susceptible to ribozyme cleavage. Ribozymes were effective in inhibiting alpha 1AT expression in a human hepatoma cell line using a newly developed simian virus (SV40) vector system. In addition, the hepatoma cell line was stably transduced with a modified alpha 1AT cDNA that was capable of producing wildtype alpha 1AT protein, but was not cleaved by the ribozyme that decreased endogenous alpha 1AT expression. These results suggest that ribozymes can be employed for the specific inhibition for an abnormal alpha 1AT gene product, the first step in designing a gene therapy for the disease. The findings also suggest that the novel SV40-derived vector may represent a fundamental improvement in the gene therapeutic armarmentarium.  (+info)

Alpha1-antitrypsin deficiency allele carriers among lung cancer patients. (8/411)

Lung cancer (LC) and chronic obstructive pulmonary lung diseases (COPDs; including emphysema and chronic bronchitis) share a common etiology. Despite the known associations of alpha1-antitrypsin deficiency (alpha1AD) with COPD and COPD with LC, few studies examined the association of alpha1AD alleles and LC. We hypothesize that heterozygous individuals who carry a deficient allele of the alpha1AD gene Pi (protease inhibitor locus) are at an increased risk of developing LC. The Pi locus is highly polymorphic with >70 variants reported. There are at least 10 alleles associated with deficiency in alpha1-antitrypsin. Using an exact binomial test, we compared the alpha1AD carrier rate in 260 newly diagnosed Mayo Clinic LC patients to the reported carrier rate in Caucasians in the United States (7%). alpha1AD carrier status, determined by isoelectric focusing assay, was examined with respect to the history of cigarette smoking, COPD, and histological types. Thirty-two of the 260 patients (12.3%; 95% confidence interval, 8.6-16.9%) carried an alpha1AD allele, which was significantly higher than expected (P = 0.002). Twenty-four of the 32 carriers had allele S, 6 had allele Z, and 2 had allele I. Patients who never smoked cigarettes were three times more likely to carry a deficient allele (20.6%; P = 0.008), although smokers had a higher carrier rate (11.1%; P = 0.025) when compared with the 7% rate. Patients with squamous cell or bronchoalveolar carcinoma had a significantly higher carrier rate than expected (15.9% and 23.8%, P < or = 0.01, respectively). Our preliminary findings suggest that individuals who carry an alpha1AD allele may have an increased risk for developing LC, specifically squamous cell or bronchoalveolar carcinoma.  (+info)

Introduction Alpha-1 antitrypsin deficiency (AATD) is a hereditary disorder affecting about 1 in 3000 people in the UK commonly associated with early-onset emphysema. There are two common deficiency alleles - PiS and PiZ. PiZZ patients have severe AATD, with levels of 10-15% normal. PiSZ patients have less severe deficiency (≈ 40% normal) and are generally thought to have a minimal risk. We hypothesised that if PiSZ patients were at lower risk of COPD than PiZZ, and their lung disease would be more characteristic of usual COPD than that of PiZZ patients.. ...

Background Alpha-1 antitrypsin deficiency is an inherited disorder that can cause lung disease (chronic obstructive pulmonary disease or COPD, which is a chronic lung condition that prevents the air supply from getting to the lungs). It affects about 1 in 1600 to 1 in 5000 people. Patients with lung disease suffer from shortness of breath, reduced ability to exercise and wheezing. People who smoke are more seriously affected and have a greater risk of dying from the disease.. Study characteristics We reviewed the benefits and harms of treating patients who have the form of the disease that affects the lungs with alpha-1 antitrypsin extracted from blood donations. We found three randomised clinical trials (283 participants in the analyses) comparing treatment with alpha-1 antitrypsin with placebo (a pretend treatment) for two to three years. All participants were ex-smokers or had never smoked but had the genetic problem that carried a high risk of developing lung problems. The evidence is ...

Alpha 1 Antitrypsin Deficiency is a genetic disorder which may lead to liver disease. Learn about Alpha 1 Antitrypsin Deficiency symptoms and more.
Inherited alpha-1 antitrypsin deficiency (A1ATD) is listed among the three most common genetic disorders in Caucasians. It considerably increases the risk of progressive obstructive lung diseases, mostly chronic obstructive pulmonary disease. Data on the A1ATD prevalence in Poland are scarce, no studies with large enough groups representative for whole Polish population have been performed. Here, we present the preliminary data on the incidence of A1AT main deficiency alleles from the newborn screening in Mazovia (Central Poland) region. Real-time PCR genotyping and A1AT blood concentration measurement by nephelometry were performed from the dry blood spots (DBS) samples of 658 newborns. Deficiency alleles PI*Z i PI*S were present in 28 children, respectively in 2.8% and 1.5%. Their existence corresponded with significantly lower A1AT blood concentration. Estimated incidence of deficiency alleles was 13,7/1000 (95% CI 5.8-21.5) for PI∗Z and 7.6/1000 (95% CI 1.7- 13.5) for PI∗S. The ...

The pattern of α1AT biosynthesis was not intracellular accumulation as observed with the common Z α1AT deficiency allele, but reduced intracellular α1AT, suggesting intracellular degradation of the newly synthesized Wbethesda molecule. Together these observations suggest that in ...

Alpha-1 antitrypsin deficiency (AATD) is a common, potentially lethal inborn disorder caused by mutations in alpha-1 antitrypsin (AAT). Homozygosity for the Pi*Z variant of AAT (Pi*ZZ genotype) causes lung and liver disease, whereas heterozygous Pi*Z carriage (Pi*MZ genotype) predisposes to gallstones and liver fibrosis. The clinical significance of the more common Pi*S variant remains largely undefined and no robust data exist on the prevalence of liver tumours in AATD.Baseline phenotypes of AATD individuals and non-carriers were analysed in 482 380 participants in the UK Biobank. 1104 participants of a multinational cohort (586 Pi*ZZ, 239 Pi*SZ, 279 non-carriers) underwent a comprehensive clinical assessment. Associations were adjusted for age, sex, body mass index, diabetes and alcohol consumption.Among UK Biobank participants, Pi*ZZ individuals displayed the highest liver enzyme values, the highest occurrence of liver fibrosis/cirrhosis (adjusted OR (aOR)=21.7 (8.8-53.7)) and primary ...
This is a pilot study to test the effect of double dose augmentation therapy with Zemaira (CSL Behring) on lung inflammation, compared with standard doses of 60 mg/kg/week.. Our hypothesis is that some patients with AATD receiving augmentation therapy at the standard dose of 60 mg/kg/week continue to have a significant lung inflammation that may lead to detrimental clinical consequences. This inflammation can be further reduced with higher AAT dosing.. The study will enroll 20 subjects with AATD and COPD already receiving augmentation therapy with any brand at standard doses for at least a month. For inclusion and exclusion criteria see below.. Protocol:. The study will take place over approximately 12 weeks: a month receiving Zemaira at standard dose (60 mg/kg/week), a month at double dose (120 mg/kg/week) and a month at standard dose (60 mg/kg/week). The infusions at standard doses will be done at home and infusions with higher doses will be provided at the study site.. the study involves ...
phdthesis{a13a8c55-510f-4fb9-a532-a58534436a33, abstract = {Alpha-1-antitrypsin (AAT) is a glycoprotein synthesised in the liver. Its main role is to protect lung tissue from destruction by neutrophil elastase. In severe (PiZZ) AAT deficiency, there is an increased risk of emphysema, especially in smokers. The deficiency is caused by the retention and aggregation by polymerization of the AAT molecules in the liver, which increases the risk of neonatal cholestasis in infancy, and cirrhosis and hepatocellular carcinoma in adulthood.

UNLABELLED: Alpha-1-antitrypsin deficiency [AATD] is associated with variable development of emphysema and other features of chronic obstructive pulmonary disease [COPD]. Matrix metalloproteinases [MMPs] are believed to be important in the pathophysiology of COPD, and may therefore confer susceptibility to this phenotype in patients with AATD. OBJECTIVES: to assess the role of polymorphism of MMP1, MMP3 and MMP12 in AATD phenotypes. METHODS: 424 PiZZ subjects from the UK AATD Registry were assessed for history of chronic bronchitis [CB], post-bronchodilator lung function impairment and decline of lung function. Tag single nucleotide polymorphisms (SNPs) for MMP1, MMP3 and MMP12 were chosen using HapMap [r(2)|0.8, MAF|0.05] and were genotyped using TaqMan genotyping technologies. Quantitative genetic association was assessed using regression modelling to correct for covariates. RESULTS: in patients with AATD, carriers of the G allele of rs678815 [MMP3] had lower gas transfer [KCO] [P = 0.025, B =-7.766]
Alpha-1 antitrypsin is the main inhibitor of neutrophil elastase in the lung. Although it is principally synthesized by hepatocytes, alpha-1 antitrypsin is also secreted by bronchial epithelial cells. Gene mutations can lead to alpha-1 antitrypsin deficiency, with the Z variant being the most clinically relevant due to its propensity to polymerize. The ability of bronchial epithelial cells to produce Z-variant protein and its polymers is unknown. We investigated the expression, accumulation, and secretion of Z-alpha-1 antitrypsin and its polymers in cultures of transfected cells and in cells originating from alpha-1 antitrypsin-deficient patients. Experiments using a conformation-specific antibody were carried out on M- and Z-variant-transfected 16HBE cells and on bronchial biopsies and ex vivo bronchial epithelial cells from Z and M homozygous patients. In addition, the effect of an inflammatory stimulus on Z-variant polymer formation, elicited by Oncostatin M, was investigated. Comparisons of groups
article{8610527, abstract = {Despite recent improvements, α1-antitrypsin deficiency (AATD) remains a rarely diagnosed and treated condition. To assess the variability of AATD diagnosis/treatment in Europe, and to evaluate clinicians views on methods to optimise management, specialist AATD clinicians were invited to complete a web-based survey. Surveys were completed by 15 physicians from 14 centres in 13 European countries. All respondents perceived the AATD diagnosis rate to be low in their country; 77% of physicians believed that ∼15% of cases were diagnosed. Low awareness was perceived as the greatest barrier to diagnosis. Spirometry was considered more practical than quantitative computed tomography (QCT) for monitoring AATD patients in clinical practice; QCT was considered more useful in trials. AAT therapy provision was reported to be highly variable: France and Germany were reported to treat the highest proportion (∼60%) of diagnosed patients, in contrast to the UK and Hungary, ...

Chronic obstructive pulmonary disease (COPD) is a common and complex condition that affects millions of Americans. Primary care clinicians see these patients routinely and are familiar with the challenges of diagnosis, assessment, and effective management. Unfortunately, many patients with COPD remain undiagnosed and untreated and continue to suffer functional limitations and reduced quality of life. The disease is also heterogeneous, with multiple pathophysiologic mechanisms, risk factors, and clinical presentations. One contributor to COPD that is widely underrecognized is alpha-1 antitrypsin deficiency (AATD). This enzyme deficiency is a genetic condition that increases risk for emphysema and other conditions, leading to accelerated decline in lung function and increased mortality. Specific tests and effective therapies for AATD are available and can slow the progression of emphysema in affected patients - but these tests and treatments are often ignored. This monograph reviews the diagnosis ...
Alpha 1-antitrypsin deficiency is an inherited disorder that can cause lung disease in adults and liver disease in adults and children. Alpha-1 antitrypsin (AAT) is a protein that protects the lungs. The liver usually makes the protein, and releases it into the bloodstream. Because of a mutation in the SERPINA1 gene, some people have little or no AAT. Not having enough AAT may lead to emphysema or liver problems. Smoking increases the risk. A deficiency of AAT can be treated but not cured. One treatment involves adding to or replacing the missing protein. More severe cases may require a lung transplant. This condition is caused by mutations in the SERPINA1 gene and inherited in an autosomal co-dominant fashion ...

Lung cancer development is a multifaceted process involving environmental and genetic factors, but their intricate interaction and extent of predisposition remains ill-defined. This study investigated the role of alpha1-antitrypsin deficiency (α1ATD), chronic obstructive pulmonary disease (COPD) and tobacco smoke exposure in lung cancer development in 1856 patients with lung cancer. The two control groups were free of any cancer and comprised 1585 community residents and 902 full siblings of patients. The α1AT alleles were tested in 1443 patients, 797 unrelated controls and 902 full siblings. The carrier rate was 13.4%, 7.8% and 9.9%, respectively.. The findings suggest that α1ATD carriers are at a 70-100% increased risk of lung cancer, particularly adenocarcinoma and squamous cell subtypes (adjusted for the effects of tobacco smoke exposure and COPD). Depending on smoking intensity, smokers were noted to have a 2-9-fold higher risk of lung cancer than never smokers. The study also confirmed ...

The hereditary disorder alpha-1 antitrypsin (AAT) deficiency results from mutations in the SERPINA1 gene and presents with emphysema in young adults and liver disease in childhood. The most common form of AAT deficiency occurs because of the Z mutation, causing the protein to fold aberrantly and accumulate in the endoplasmic reticulum (ER). This leads to ER stress and contributes significantly to the liver disease associated with the condition. In addition to hepatocytes, AAT is also synthesized by monocytes, neutrophils, and epithelial cells. In this study we show for the first time that the unfolded protein response (UPR) is activated in quiescent monocytes from ZZ individuals. Activating transcription factor 4, X-box binding protein 1, and a subset of genes involved in the UPR are increased in monocytes from ZZ compared with MM individuals. This contributes to an inflammatory phenotype with ZZ monocytes exhibiting enhanced cytokine production and activation of the NF-kappaB pathway when ...

A cohort of 127 PiZZ, 2 PiZnull, 54 PiSZ, and 1 PiSnull individuals were identified by the Swedish national neonatal AAT screening program between 1972 and 1974, when all 200, 000 newborn infants in Sweden were screened for AAT deficiency.

Please refer to the alpha 1-antitrypsin for the various protease inhibitor (Pi) genotypes and phenotypes. Normally, alpha 1-antitrypsin is produced in the liver and exists in levels of 1.5-3.5 gram/litre. When the levels are reduced (40-60%, in the PiSS, PiMZ and PiSZ phenotypes), most people will only suffer symptoms if they smoke, as the levels are still sufficient to counteract normal elastase activity in inflammation. Only in the PiZZ phenotype, when the levels are less than 15%, emphysema develops at a young age, and 50% will develop liver cirrhosis due to the accumulated protein, which is not secreted properly. On liver biopsy, they show as PAS-positive, diastase-negative granules. Apart from increasing the inflammatory reaction in the airways, cigarette smoke also directly inactivates alpha 1-antitrypsin by oxidizing essential methionine residues to sulfoxide forms, decreasing the enzyme activity by a rate of 2000. ...
The AATD is a metabolic disorder that predisposes the affected individual to chronic pulmonary disease, in addition to chronic liver disease, cirrhosis, and hepatocellular carcinoma. Clinical manifestations are always present in patients with complete absence of serum alpha-1 antitrypsin (null variants). The majority of patients with ZZ or SZ genotypes, and some others with the SS genotype, have pulmonary or hepatic symptoms. Severe lung and liver disease are rarely observed in the same person. Heterozygous individuals, with both a normal and a variant allele (MZ or MS), rarely develop clinical symptoms. In most patients with symptomatic AATD, the dominant manifestation is lung disease: the symptoms appear earlier and may proceed faster if additional risk factors are present, like smoke or air pollutants. The mean life expectancy of homozygous patients (ZZ and SS variant) is from 48 to 52 years for smokers and from 60 to 68 years for nonsmokers. Severe pulmonary impairment, manifesting as COPD ...
A1AT deficiency remains undiagnosed in many patients. Patients are usually labeled as having COPD without an underlying cause. It is estimated that about 1% of all COPD patients actually have an A1AT deficiency. Testing is recommended in those with COPD, unexplained liver disease, unexplained bronchiectasis, granulomatosis with polyangiitis or necrotizing panniculitis.[10] American guidelines recommend that all people with COPD are tested,[10] whereas British guidelines recommend this only in people who develop COPD at a young age with a limited smoking history or with a family history.[14] The initial test performed is serum A1AT level. A low level of A1AT confirms the diagnosis and further assessment with A1AT protein phenotyping and A1AT genotyping should be carried out subsequently.[15] As protein electrophoresis does not completely distinguish between A1AT and other minor proteins at the alpha-1 position (agarose gel), antitrypsin can be more directly and specifically measured using a ...

Objective: Exclusively breastfed infants with unrecognised cholestatic jaundice are at high risk of a vitamin K deficiency (VKD) bleeding. It is presently unknown whether (the size of) this risk depends on the degree of cholestasis. Since alpha-1-antitrypsin deficiency (A1AD) induces a variable degree of cholestasis, we assessed the risk of VKD bleeding in infants with cholestatic jaundice due to A1AD.. Patients and methods: Infants with a ZZ or SZ phenotype born in The Netherlands between January 1991 and December 2006 were identified from the databases of the five Dutch diagnostic centres for alpha-1-antitrypsin phenotyping and/or genotyping. We determined the risk of VKD bleeding upon diagnosis of A1AD in breastfed and formula fed infants and searched for correlations between serum levels of conjugated bilirubin and the risk of bleeding.. Results: A total of 40 infants with A1AD were studied. VKD bleeding was noted in 15/20 (75%) of breastfed infants, compared with 0/20 of formula fed infants ...
AATD can present as lung disease in adults and can be associated with liver disease in a small portion of affected children. In affected adults, the first symptoms of AATD are shortness of breath with mild activity, reduced ability to exercise and wheezing. These symptoms usually appear between the ages of 20 and 40. Other signs and symptoms can include repeated respiratory infections, fatigue, rapid heartbeat upon standing, vision problems and unintentional weight loss.. Some Individuals with AATD have advanced lung disease and have emphysema, in which the small air sacs (alveoli) in the lungs are damaged. Symptoms of emphysema include difficulty breathing, a hacking cough and a barrel-shaped chest. Smoking or exposure to tobacco smoke increases the appearance of symptoms and damage to the lungs. Other common diagnoses include COPD (chronic obstructive pulmonary disease), asthma, chronic bronchitis and bronchiectasis - a chronic inflammatory or degenerative condition of one or more bronchi or ...

Alpha-1 antitrypsin (AAT) deficiency is a condition in which the body does not make enough of AAT, a protein that protects the lungs and liver from damage.
More than 120 mutations in the SERPINA1 gene have been identified. Some of these mutations do not affect the production of alpha-1 antitrypsin, while others cause a shortage (deficiency) of the protein. Without enough functional alpha-1 antitrypsin, neutrophil elastase destroys the small air sacs in the lungs (alveoli) and causes lung disease. Excessive damage to the alveoli leads to emphysema, an irreversible lung disease that causes extreme shortness of breath.. Many SERPINA1 gene mutations change single protein building blocks (amino acids) in alpha-1 antitrypsin, which alters the proteins structure. The most common mutation that causes alpha-1 antitrypsin deficiency replaces the amino acid glutamic acid with the amino acid lysine at protein position 342 (written as Glu342Lys or E342K). This mutation results in a version of the SERPINA1 gene called the Z allele that produces very little alpha-1 antitrypsin.. Abnormal alpha-1 antitrypsin proteins may bind together to form a large molecule, or ...
Alpha-1-antitrypsin or α1-antitrypsin (A1AT, A1A, or AAT) is a protein belonging to the serpin superfamily. It is encoded in humans by the SERPINA1 gene. A protease inhibitor, it is also known as alpha1-proteinase inhibitor (A1PI) or alpha1-antiproteinase (A1AP) because it inhibits various proteases (not just trypsin). In older biomedical literature it was sometimes called serum trypsin inhibitor (STI, dated terminology), because its capability as a trypsin inhibitor was a salient feature of its early study. As a type of enzyme inhibitor, it protects tissues from enzymes of inflammatory cells, especially neutrophil elastase, and has a reference range in blood of 0.9-2.3 g/L (in the US the reference range is expressed as mg/dL or micromoles), but the concentration can rise manyfold upon acute inflammation. When the blood contains inadequate amounts of A1AT or functionally defective A1AT (such as in alpha-1 antitrypsin deficiency), neutrophil elastase is excessively free to break down elastin, ...

Alpha-1 antitrypsin (AAT) is the most abundant circulating antiprotease and is a member of the serine protease inhibitor (SERPIN) superfamily. The gene encoding AAT is the highly polymorphic SERPINA1 gene, found at 14q32.1. Mutations in the SERPINA1 gene can lead to AAT deficiency (AATD) which is associated with a substantially increased risk of lung and liver disease. The most common pathogenic AAT variant is Z (Glu342Lys) which causes AAT to misfold and polymerise within hepatocytes and other AAT-producing cells. A group of rare mutations causing AATD, termed Null or Q0, are characterised by a complete absence of AAT in the plasma. While ultra rare, these mutations confer a particularly high risk of emphysema. We performed the determination of AAT serum levels by a rate immune nephelometric method or by immune turbidimetry. The phenotype was determined by isoelectric focusing analysis on agarose gel with specific immunological detection. DNA was isolated from whole peripheral blood or dried blood spot
In the present study, we evaluated the impact of the two most relevant AAT variants in two large and well-characterised cohorts of biopsy-proven NAFLD (both cohorts: n=1184) and chronic alcohol misuse (both cohorts: n=2462). We unambiguously found that the Pi*Z variant is a major risk factor for cirrhosis in the context of chronic metabolic injury such as NAFLD and chronic alcohol misuse. These findings are in line with previously published, smaller studies or studies pointing to an association with end-stage liver disease or cryptogenic cirrhosis in general.12 14 15 17 18 21 22 24 25 36 These findings provide a definitive answer and end the controversy about the clinical relevance of heterozygous carriage of the Pi*Z variant in NAFLD and ALD (online supplementary table 1). Moreover, this study is the first report that has systematically investigated the role of the Pi*S variant providing evidence that this variant does not pose a major risk to develop alcoholic or NAFLD-associated cirrhosis. ...

Chronic obstructive pulmonary disease (COPD) is a representative chronic inflammatory disorder of the lungs that includes chronic bronchitis and emphysema. COPD is characterized by airway inflammation and progressive airflow obstruction, most commonly caused by cigarette smoking. The major symptoms of which patients complain are cough, breathlessness, and sputum production. COPD is associated with underlying inflammation in response to chronic exposure to noxious particulates and gases and with a number of comorbid conditions. The onset of COPD generally occurs in the 6th to 8th decades of life. Early onset COPD is defined as disease onset before the age of 50 years, irrespective of smoking history. The presence of persons with early onset, severely reduced pulmonary function suggests that individuals may vary in their genetic susceptibility to the effects of smoking. Alpha-1-antitrypsin deficiency is the only proven genetic risk factor for COPD. Bronchodilators are the mainstay of treatment ...

Cumulative evidence has shown that a delicate balance between serine proteases and their inhibitors is crucial for normal functioning of several biological pathways. The importance of proteases and their inhibitors is well documented in several human diseases. Among them, the best documented are hemophilia B, a genetic deficiency of the serine protease coagulation factor IX and serpinophathies. Alpha-1-antitrypsin deficiency (MIM 107400), is associated with early-onset emphysema and liver disease, while hereditary angioedema (HANE; MIM 106100) is caused by mutations in the C1 inhibitor, a serpin involved in the regulation of the complement cascade. Recently, two human genetic diseases of the central nervous system have been related to mutations in components of extracellular proteolytic systems. Here, we review the recent advances in this field. [References: 38].. Oct 15;12(Spec 2):R195-200. Available online at: http://hmg.oxfordjournals.org/content/12/suppl_2/R195.long. ...
The majority of serpin diseases are due to protein aggregation and are termed serpinopathies.[9][63] Serpins are vulnerable to disease-causing mutations that promote formation of misfolded polymers due to their inherently unstable structures.[63] Well-characterised serpinopathies include α1-antitrypsin deficiency (alpha-1), which may cause familial emphysema and sometimes liver cirrhosis, certain familial forms of thrombosis related to antithrombin deficiency, types 1 and 2 hereditary angioedema (HAE) related to deficiency of C1-inhibitor, and familial encephalopathy with neuroserpin inclusion bodies (FENIB; a rare type of dementia caused by neuroserpin polymerisation).[8][9][68]. Each monomer of the serpin aggregate exists in the inactive, relaxed conformation (with the RCL inserted into the A-sheet). The polymers are therefore hyperstable to temperature and unable to inhibit proteases. Serpinopathies therefore cause pathologies similarly to other proteopathies (e.g. prion diseases) via two ...

For genotypes conferring a diagnosis of a single gene disorder, such as factor V Leiden or hemochromatosis, the risk-benefit ratios are among the most favorable, but even here there are concerns that such testing is not cost effective, is not evidence based and may lead to stigmatization or undue anxiety [15, 16]. Assuming low-cost and high-throughput genotyping and good physician and patient education, this form of testing carries relatively few ethical concerns in my view. If physician and patient education are lacking, inappropriate outcomes or management may result.. Evidence-based practice should dictate any change in management based on genotype. With proper physician and patient comprehension, there are potential clinical benefits and relatively little downside to knowing that an individual is at increased risk of thrombosis related to factor V Leiden, emphysema related to α1-antitrypsin deficiency, or death related to hemochromatosis. Just as physicians have routinely incorporated ...

There is a form of Emphysema influenced by a long period of smoking called Smokers Emphysema. It develops usually in older patients. Another type of Emphysema is the one with a hereditary transmission. In this case there is a deficiency of alpha-i-antitrypsin (AAT), but just one to three percent of all cases of Emphysema are due to AAT deficiency. This happens because in the lungs, at cells level there is an imbalance between elastin and AAT. The reaction between this two proteins is mediate by an enzyme called elastase. When there is a genetic deficiency of AAT the elastin degradation occurs unchecked. This phenomenon is worsen if the patients with genetic deficiency of AAT smoke and the symptoms appears early middle age. The deficiency of ATT is detected by blood tests made in specialized laboratories ...
