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)

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 ...
Blancos Overview of Alpha-1 Antitrypsin Deficiency: History, Biology, Pathophysiology, Related Diseases, Diagnosis, and Treatment is a robust introduction to topics associated with Alpha-1 Antitrypsin Deficiency (AATD). Included are topics ranging from the history of the disease, biology, pathophysiology, related diseases, including the two major manifestations of the disease (liver disease and lung disease), and diagnosis and treatment.. The book addresses the need for the amalgamation of current and novel concepts and practices in the field of AATD. AATD is under-recognized in the medical community and, as a result, it is underdiagnosed. The book provides increased awareness and understanding of the condition to improve diagnosis rates and enhance patient care. This book is an essential tool and reference, beneficial to clinicians who screen and treat AATD patients, as well as research scientists working in the AATD field at junior and senior levels.. ...
The question of whether higher doses of alpha1-PI (,60 mg/kg) are able to provide better protection to patients with alpha 1-antitrypsin deficiency is currently unknown. As a first step to address this question, the present study has been undertaken. This is a multi-center, randomized, double-blind, crossover study to assess the safety and pharmacokinetics of weekly infusions of 120 mg/kg of Prolastin-C, compared to weekly infusions of 60 mg/kg of Prolastin-C in patients with alpha 1-antitrypsin deficiency. This study is a crossover design with 2 treatment sequences:. Treatment Sequence 1: 60 mg/kg weekly infusion of Prolastin-C for 8 weeks followed by 120 mg/kg weekly infusion of Prolastin-C for 8 weeks (starting at Week 1) (total of 16 treatment weeks). Treatment Sequence 2: 120 mg/kg weekly infusion of Prolastin-C for 8 weeks followed by 60 mg/kg weekly infusion of Prolastin-C for 8 weeks (starting at Week 11) (total of 16 treatment weeks). Approximately 15 subjects are planned to be entered ...
AAT deficiency is a genetic disorder associated with emphysema. Spirometry, the lung function test that measures how well the lungs exhale air, is used to diagnose and track the progression of emphysema. Some studies have suggested that forced expiratory volume in 1 second (FEV1) measurements, a type of spirometry test, may lack accuracy in detecting disease progression in cases of severe AAT deficiency. Another method, high resolution chest CT scans, may be more accurate at measuring the progression of emphysema. The purpose of this study is to determine if high resolution CT scans are better at detecting the progression of emphysema than lung function tests. Results from this study may lead to the development of a more accurate way to assess lung tissue loss and may improve the understanding of lung destruction in AAT deficiency.. This study will last 4 years and will enroll people with AAT deficiency who have nearly normal lung function test results. Study visits, each lasting about 4 hours, ...
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 ...

BACKGROUND: Alpha-1 antitrypsin deficiency (AATD) results from mutations in the SERPINA1 gene and classically presents with early-onset emphysema and liver disease. The most common mutation presenting with clinical evidence is the Z mutation, while the S mutation is associated with a milder plasma deficiency. AATD is an under-diagnosed condition and the World Health Organisation recommends targeted detection programmes for AATD in patients with chronic obstructive pulmonary disease (COPD), non-responsive asthma, cryptogenic liver disease and first degree relatives of known AATD patients. METHODS: We present data from the first 3,000 individuals screened following ATS/ERS guidelines as part of the Irish National Targeted Detection Programme (INTDP). We also investigated a DNA collection of 1,100 individuals randomly sampled from the general population. Serum and DNA was collected from both groups and mutations in the SERPINA1 gene detected by phenotyping or genotyping. RESULTS: The Irish National
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, ...

Introduction Alpha-1 antitrypsin deficiency (AATD) is a genetic condition associated with COPD; patients homozygous for the mutant Z allele (PiZZ) are predisposed to severe, early-onset emphysema of the lung, and also progressive fibrosis and cirrhosis of the liver. There is a well-known association between COPD and cardiovascular disease, with around 1 in 3 COPD deaths attributed to a cardiac cause.1 We hypothesised that cardiovascular risk in AATD may be independently modified by the severity of lung and liver disease, through common or related pathophysiological processes. ...
Liver disease associated with alpha-1-antitrypsin deficiency, classically described in protease inhibitor (Pi)-type ZZ phenotype children, characteristically shows variable fibrosis or cirrhosis and distinctive periodic acid-Schiff-positive (diastase-resistant) globules, containing alpha-1-antitrypsin, within periportal hepatocytes. In adults, liver involvement may occur without lung disease, and severely affected heterozygotes (non-ZZ individuals) have been reported. However, the significance of alpha-1-antitrypsin liver disease in adults remains undefined (1, 2).. Case 1, a 73-year-old man, presented with biochemical evidence of liver disease in 1971 during hospitalization for unrelated medical problems. Total bilirubin was 1.0 mg/dl (normal , 1.0), alkaline phosphatase 145 IU (normal, 9 to 35), serum ...
article{23bc97b5-44c3-44d9-8ce7-616d5254f6f0, abstract = {Background: Severe (PiZZ) and moderate (PiSZ) alpha-1-antitrypsin (AAT) deficiency predispose to lung emphysema, especially in smokers. We hypothesized that multi-slice computed tomography (CT) might be superior to pulmonary function tests (PFT) to detect lung emphysema in AAT-deficient individuals at the age of 32 years. Methods: A subgroup of PiZZ and PiSZ individuals identified during the Swedish newborn screening programme in 1972-74 underwent multi-slice CT and PFT at the age of 32 years. From the CT scans the percentile density at 15% (PD15) and the relative area below -910 Hounsfield Units (RA(-910) HU) were calculated. The results of PFT and CT were compared between the AAT-deficient individuals and an age-matched control group. Results: Twenty-five PiZZ, 11 PiSZ and 17 PiMM individuals participated in the study. All Pi subgroups had normal lung function. The mean PD15 was 81 (SD 22) g/L in the PiZZ individuals, 96 (SD 35) g/L in ...
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 ...

article{28d5c2ad-b244-4d8a-b7d9-b8f6b4fb3b95, abstract = {,p,Severe alpha-1-antitrypsin (AAT) deficiency (PiZZ) is a risk factor for liver disease, but the prevalence of liver cirrhosis and hepatocellular cancer in PiZZ adults is unknown. The risk of liver disease in adults with moderate AAT deficiency (PiSZ) is also unknown. 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. The cohort has been followed up since birth. Our aim was to study liver function and signs of liver disease in this cohort at 37 to 40 years of age in comparison with a matched, random sample of control subjects identified from the population registry. Eighty seven PiZZ, 32 PiSZ, and 92 control subjects (PiMM) answered a questionnaire on medication and alcohol consumption and provided blood samples. Liver stiffness was assessed by ...
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 ...

Alpha 1-antitrypsin deficiency is a genetic disorder caused by defective production of alpha 1-antitrypsin (AAT). Gene therapy approaches have been conducted in patients with AAT deficiency with successful AAT expression, but not to the therapeutic levels required to reduce the risk of emphysema. Codon optimization, a somewhat new and evolving technique, is used by many scientists to maximize protein expression in living organisms by altering translational and transcriptional efficiency as well as protein refolding. The purpose of this study was to develop single stranded and double stranded AAT gene constructs, test their protein expression in vitro, and compare with those levels expressed by the AAT construct that is currently in clinical trials. Three constructs were to be developed, yet only one construct was successfully cloned. This clone, optimized ds-CB-AAT, illustrated increased AAT protein expression as the transfection time increased. However, protein levels were appreciably lower in

Results 7296 unique records were reviewed with 51 trials analysed on 5632 participants: 26 AAT-augmentation (3 for meta-analysis); 17 surgical intervention (5 Lung volume reduction (LVR) surgery, 1 Bronchoscopic valve LVR and 11 Lung transplantation); 3 medical interventions and 3 trials completed but not published.. Meta-analysis of AAT-Augmentation demonstrated slower lung CT density decline, difference 0.79 g/l/year (95% CI: 0.29-1.29; p = 0.002), and a small increase in annual exacerbations 0.29/year (95% CI: 0.04-0.54; p = 0.02) compared to placebo (Figure 1).. Survival benefit of transplant was observed in one study (p = 0.006) but not in a second with more stringent matching for groups; however significant improvements in health status, total SGRQ and all domain scores, at one year (p , 0.01) were observed. Mortality post lung transplant was comparable between AATD and non-AATD related COPD cohorts. Surgical lung volume reduction demonstrated inferior outcomes when compared to non-AATD ...
When testing doesnt find a mutation, there are two possible explanations - you may not have inherited either of the mutations that cause Alpha-1 in your family or the mutation that causes Alpha-1 in your family cant be found with the test that was done. In this situation, a normal result doesnt rule out the chance that you are an Alpha-1 carrier. However, it is very unlikely that you have Alpha-1 or are a carrier. Genetic testing finds about 95% of the mutations that cause Alpha-1 ...
Introduction. Cystic fibrosis (CF) is the most common and lethal autosomal recessive genetic diseases and affects one in 2,500 Caucasians. The risk of its heterozygote in the general population is one to 25. More than 1,000 mutations have been identified to the CFTR gene1, which codes for a protein containing 1,489 amino acids. Cystic Fibrosis is characterized by abnormal chlorine flow at the apical membrane of epithelial cells, causing diverse clinical manifestations including pancreatic insufficiency, lung disease, meconium ileus, elevated sweat chlorine levels and obstruction of the vas deferens. The extreme diversity of CF phenotypes is probably influenced by other genetic areas, distant from the CFTR locus. Many of the genes that are studied nowadays as modifiers of CF, particularly among those that influence the severity of the lung disease, are involved in controlling infection, immunity and inflammation. Some of these include the class II HLA antigens, mannose-binding lectin and alpha 1 ...

Purpose : Mutations in the KCNJ13 gene, encoding the inwardly rectifying potassium Kir7.1 ion-channel in the RPE, cause autosomal dominant snowflake vitreoretinal degeneration (SVD) and autosomal recessive Lebers congenital amaurosis (LCA16). Molecular and biophysical analysis of the mutant protein revealed a non-functional protein product. With a goal of restoring retinal function via gene augmentation therapy, we tested the efficacy of Kir7.1 channel functional rescue using an in vitro model of CHO cells expressing disease - associated mutations. Methods : We cloned human Kir7.1-WT (wild-type) and W53X (mutant) into Flip-In™ expression vector (ThermoFisher Scientific) and transfected them into Chinese Hamster Ovary (CHO) cells to express the protein products. Expression of Kir7.1 was verified through PCR and Restriction fragment length polymorphism (RFLP) analysis. Whole-cell configuration of patch-clamp technology was used to measure Kir7.1 current. Protein expression was confirmed by ...
The measurement of forced expiratory volume in 1 second (FEV1) and its decline over time are prognostic indicators of early chronic airflow obstruction. Although alpha1-antitrypsin (AAT) deficiency (Z allele) was shown to be a risk factor for rapid decline in lung function, individuals with the same AAT genotype may differ in their phenotypes suggesting the presence of other genetic modifiers.

Chemical chaperones and low growth temperature are often used as a first step to evaluate the feasibility of treatments using pharmacological chaperones for secretion-impaired mutations. In this context, the examples of the CFTR ΔF508 or α1-antitrypsin Z variants responsible for cystic fibrosis and α1-antitrypsin deficiency, respectively, are promising.16-18 In our transfected cell model we found that none of the chemical chaperones used (4-PBA, DMSO and TMAO) restored the secretion of the fibrinogen mutants studied. By contrast, low-temperature incubation (27°C) allowed partial secretion of the Bβ p.G444S (p.G414S) and γ p.W253C (p.W227C) mutants. Low temperature may act kinetically by slowing down the folding process thus allowing a higher amount of mutant proteins to adopt a suitable conformation and reach their final destination.17 Interestingly, in this condition, the two nonsense mutants Bβ p.W467X (p.W437X) and Bβ p.R485X (p.W455X) were not secreted. This suggests a more severe ...
Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease characterized by airflow limitation that is progressive and associated with an enhanced chronic inflammatory response in the lung to noxious particles or gases. Deficiency of alpha-1 antitrypsin (AAT) is the best-studied genetic risk factor for COPD and one of the most common genetic disorders among Caucasians. The availability of specific therapy for AATD makes it possible to improve outcomes, but however, AATD is underrecognized and undertreated. This program will discuss diagnosis and treatment options for patients with COPD and AATD, with the most recent recommendations from the GOLD 2017 report..

Three pools of exhaled breath condensate (EBC) from non-smokers plus healthy smokers (NS + HS, n = 45); chronic obstructive pulmonary disease (COPD) without emphysema (COPD, n = 15) and subjects with pulmonary emphysema associated with α1-antitrypsin deficiency (AATD, n = 23) were used for an exploratory proteomic study aimed at generating fingerprints of these groups that can be used in future pathophysiological and perhaps even clinical research. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was the platform applied for this hypothesis-free investigation. Analysis of pooled specimens resulted in the production of a
My laboratory research to date has focused on using lentiviruses to develop a gene therapy for alpha-1 antitrypsin deficiency. I have approached this problem through the manipulation of two target cell populations: hematopoietic stem cells and alveolar macrophages. Both approaches have resulted in long-term expression of human alpha-1 antitrypsin in laboratory animals. In addition to the in-vivo overexpression of alpha-1 antitrypsin, I am interested in manipulating other genes which may play a role in the pathogenesis of COPD, such as NF-kB.. A second area of interest is embryonic stem cell biology. I am working with Darrell Kotton and others in our division to study the progression of definitive endoderm to lung epithelium.. ...

Hereditary C2D is the most common complement component deficiency among individuals of European descent, but is relatively rare among other ethnic groups. Here we report a case of C2D in an African-American family. The proband of this family and his asymptomatic youngest sister were compound heterozygotes for type I and type II C2D. The type I C2D allele was inherited from their father, and the type II C2D allele was inherited from their mother. The former was associated with the HLA-A25, -B18, -DR15 haplotype and carried the 28-bp deletion in exon 6, which characterizes the common type I C2D seen among Europeans. The type II C2D allele carried a novel G392A mutation in exon 3 of the C2 gene, which led to a Cys111→Tyr substitution. Cys111 is the invariable third half-cystine of the second CCP module of C2, and its substitution with Tyr was shown to be responsible for blocking the secretion of the C2 polypeptide by COS cells transfected with mutant cDNA.. The mechanism leading to type II C2D ...
In Response:. We appreciate the comments raised by Dahl et al in the letter above. However, there are a number of differences in the study design reported in our article published in Arteriosclerosis, Thrombosis, and Vascular Biology1 and that of both Dahl et al2 and Elzouki et al,3 which could have led to discrepancies in the concluded role for alpha-1-antitrypsin (AAT). While our study examined the association of common and rare AAT variants with progression of atherosclerosis in individuals with well defined atherosclerotic disease, the others looked at the occurrence of ischemic heart disease (IHD) or ischemic cerebrovascular disease (ICVD) in individuals who carried rare AAT deficiency genotypes compared with controls. Atherosclerosis progression, IHD, and ICVD are very different disease endpoints, and furthermore, the causes of ischemia are multiple.4 In addition, while our study is a prospective analysis of angiographically defined disease, the other two are case:control analyses. So the ...

On average, we take 20,000 breaths every day. Our lungs are one of the largest organs of the body, and they do a lot of work 24/7 to keep us alive. If you have chronic obstructive pulmonary disease (COPD), it can change your life. Its a disease that causes obstructed airflow of the lungs and produces symptoms such as coughing, wheezing and shortness of breath. Lets examine a few facts and fallacies regarding COPD so that you can keep your lungs healthy.. 1. COPD is caused by smoking.. TRUE. Smoking tobacco with cigarettes, cigars or pipes is, by far, the No. 1 cause of COPD. Over time, smoking does irreversible damage to the inside of the lungs. But there are other causes of COPD, such as prolonged exposure to second-hand smoke, air pollution and occupational dust, smoke or chemical fumes. There are also rare cases of COPD that result from a genetic disorder called alpha-1-antitrypsin deficiency. 2. COPD is easy to catch early.. FALSE. COPD develops slowly over many years, so most people are ...
Treatment for genetically caused emphysema effective A landmark clinical study provides convincing evidence that a frequently overlooked therapy for genetically-caused emphysema is effective and slows the progression of lung disease. Alpha-1 antitrypsin deficiency is an inherited disorder that can cause emphysema even without exposure to tobacco smoke. ...
Every year, thousands of people die because of typos in their genes. Theres a long list of debilitating or fatal genetic diseases that are caused by a single incorrect DNA letter among the three billion in our genome. Its the equivalent of pulping an entire encyclopaedia on the basis of a single typo. But hope is at hand. We are fast approaching the point when we can proofread these errors out of our genes.. Kosuke Yusa and Tamir Rashid have taken the latest step towards this goal, by developing a more efficient and less risky way of correcting genetic errors. They took cells from patients with a genetic liver disease, edited the gene responsible, and grew corrected liver cells that successfully treated mice with the same disease.. The disease in question is called alpha 1-antitrypsin deficiency (or alpha-1 for short). It affects 1 in every 2,000 Europeans and is caused by a single typo in the A1AT gene. The error stops people from making enough of the A1AT protein. The little they do make ...
Two weeks after Shire punted rights to one of its therapies, Israels Kamada $KMDA says that it is yanking its marketing application at the EMA for its inhaled therapy for rare cases of Alpha-1 Antitrypsin Deficiency after concluding that regulators will want to see data from another trial before they consider hitting the green light.. Kamada provided post-hoc data to back its case on a statistically significant and clinically relevant improvement in lung function among patients, but European regulators werent buying it.. Kamadas shares plunged 26% as the news spread.. The plan now is to push through a pivotal Phase III study in the US - the application is in - and then take that data back to the EMA while looking to field an application at the FDA as well.. Its been a bad month for Kamada. On June 7 the biotech reported that Shire was hitting the brakes on a Phase II/III study of G1-AAT IV for the treatment of acute graft-versus-host disease and handing rights to the drug back to the ...

The researchers compared the ability of both genome editing systems to either cut out pieces of known genes in iPSCs or cut out a piece of these genes and replace it with another. As model genes, the researchers used JAK2, a gene that when mutated causes a bone marrow disorder known as polycythemia vera; SERPINA1, a gene that when mutated causes alpha1-antitrypsin deficiency, an inherited disorder that may cause lung and liver disease; and AAVS1, a gene thats been recently discovered to be a "safe harbour" in the human genome for inserting foreign genes ...
ABSTRACT. Nation-wide neonatal screening for α1-antitrypsin deficiency (ATD) in Sweden was discontinued due to observations that identification of ATD in newborns seemed in some cases to have negative psychological effects on the parents and the parent-child relationship. A multifaceted study was developed to investigate systematically the psychological and psychosocial consequences of the identification of ATD in the neonatal period, as studied five to seven years after it took place. The studys basic goals, hypotheses, design, samples and methods are described. ...
Protein misfolding events has over the past 20 years been associated with the pathogenesis of multiple diseases, ranging from diseases of genetic origins (Cystic Fibrosis/1-alpha antitrypsin deficiency) to metabolic disorders (Diabetes) and cancer. We are interested to learn more about the molecular events that occurs when proteins are not folded correctly in the endoplasmic reticulum (ER) and to elucidate the downstream activation of the Unfolded Protein Response (UPR) to clarify its possible role in the initiation and progression of chronic lung disorders. We believe that increased understanding of the molecular pathwas involved in the response to cellular ER stress and protein misfolding events will enable us to identify novel molecular targets involved in both disease initiation and progression.. ...
The lumen of the endoplasmic reticulum (ER) is a highly specialized compartment in eukaryotic cells. Here, secretory and most membrane proteins are folded, covalently modified, and oligomerized with the assistance of specialized ER resident proteins (1). Perturbation of the ER lumen interferes with the production of many essential cellular components and can thus be highly deleterious. Indeed, in humans, defects in protein folding in the ER can lead to devastating diseases, such as cystic fibrosis, alpha1-antitrypsin deficiency, and osteogenesis imperfecta (2). One way in which cells cope with the accumulation of unfolded proteins in the ER is by activating the unfolded protein response (UPR), an ER-to-nucleus signal transduction pathway (3-5). In the yeast Saccharomyces cerevisiae, Ire1p is an essential component of this pathway.. ...

Laboratory evaluation of A1AT deficiency involves measurement of circulating A1AT protein (quantitation) and characterization of A1AT genetic polymorphisms. In contrast to adult and pediatric populations, there are no reliably documented A1AT serum reference ranges for newborns available. We evaluated blood samples from 145 children collected at 0-7 day after birth within the frame of on-going newborn A1AT deficiency screening program in Central Poland. A1AT and hsCRP serum concentration was measured by nephelometry, A1AT phenotyping performed by isoelectrofocusing. The median A1AT serum concentration for normal newborn population with the MM phenotype (n=135) was 172,0 mg/dL (123-331).Lower concentrations of A1AT correlated with heterozygosity for the S and Z alleles, respectively MS (n=3) 151,0 and MZ (n=3) 125,0 mg/dL. Considerable dynamics in A1AT blood level changes in the first days of life were observed with median A1AT concentration of 155,5 mg/dL at day 0, 158,5 at day1, 183,2 at day2, ...
We are very encouraged by these data with ALN-AAT and look forward to further advancement of an RNAi therapeutic approach for the treatment of this genetic disease." ALN-AAT is a new RNAi therapeutic program for the treatment of liver disease associated with AAT deficiency. New data presented at the Liver Meeting are based on an AAT-targeting siRNA formulated in a lipid nanoparticle (LNP). The AAT siRNA was administered at doses ranging from 0.03 to 1.0 mg/kg in mice overexpressing a human Z-AAT transgene, resulting in robust, dose-dependent silencing of the target mRNA and protein. Specifically, a single intravenous dose of the drug resulted in 90% knockdown of liver mRNA and a greater than 80% decrease in serum AAT at 48 hours post-dose. Furthermore, a 90% reduction in soluble protein monomers in the liver was observed at 1.0 mg/kg, with an 80% reduction seen at 0.3 mg/kg. In addition, in long-term dosing studies, in which transgenic mice overexpressing Z-AAT were dosed every other week for 12 ...
Inherited retinal degenerations (IRDs) are important causes of vision loss that affect people of all ages. These disorders cause vision loss via dysfunction and death of the photoreceptor and retinal pigment epithelial cells of the retina. Gene augmentation therapy has been shown to be beneficial for patients with specific genetic forms of IRDs to date, but IRDs are genetically heterogeneous, and gene therapy may not be possible for all of the different genetic forms of disease, such as those caused by mutations in large genes, or by dominant gain-of-function mutations. This project is to test the use of CRISPR/Cas9 - mediated genome editing to treat several genetic forms of retinal degeneration that are not amenable to standard gene augmentation therapy approaches. The role of the defined student will be to learn and apply skills in genetics, molecular and cellular biologic, and CRISPR/Cas9 genome editing for treating one of the dominant forms of IRD in patient-derived iPS cells and gene ...

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 ...

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, ...

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 ...
ANNAPOLIS, Md., Sept. 1, 2011 /PRNewswire/ -- This month, Floridians are recognizing "Plasma Protein Therapies Month," by raising awareness for the valuable contributions of plasma donors throughout the "Sunshine State" and for the rare, genetic diseases treated with the therapies that are made possible through plasma donation.. Plasma protein therapies, which include plasma-derived therapies and recombinant blood clotting factors (a biotechnology product), are used every day to treat people with bleeding disorders, such as hemophilia, that causes painful internal bleeding and debilitating joint damage; primary immunodeficiency diseases, which prevent a person from fighting off even common infections; and alpha-1 antitrypsin deficiency, also known as genetic chronic obstructive pulmonary disease (COPD), a disease that severely damages the liver and lungs. In addition, a plasma protein therapy, albumin, is used in critical care settings, when treating severe trauma, burns and during major ...
When these tests first came out, they handed you an armload of information, but no means to interpret it. The FDA realized that this information was causing people unessescary panic, so they froze the ability to provide information about genetic predisposition to diseases, only allowing companies to provide the public with their family history of origin. This past April (2017) the FDA partially lifted this ban, allowing 23andMe to provide you with your risk for 10 diseases. According to CNN, these diseases are: "Parkinsons; late-onset Alzheimers; celiac disease; a movement disorder called early-onset primary dystonia; a disorder that elevates your risk for lung and liver disease called Alpha-1 antitrypsin deficiency; a blood clotting disorder Factor XI deficiency; an organ and tissue disorder called Gaucher disease type 1; a red blood cell condition known as G6PD; hereditary hemochromatosis, an iron overload disorder; and hereditary thrombophilia, a blood clot disorder.". ...

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 ...
A 58 year old white man presented with sudden painless loss of vision to the right eye. Vision was hand movements in the right eye and 6/6 in the left. Funduscopy revealed an acute right CRAO with macular oedema. There were no signs of uveitis or retinal vasculitis. Management consisted of intravenous acetazolamide (500 mg), ocular massage, and anterior chamber paracentesis. He was subsequently sent home with aspirin treatment, and referred to his family doctor for routine risk factors assessment.. The following morning, he returned to the eye casualty department with a left CRAO, which was treated in the same way. Vision was 6/60 in the right eye and hand movements in the left. Systemic inquiry revealed a 2 month history of general malaise, arthralgia, and myalgia. General examination revealed evidence of vasculitic rash (Fig 1) affecting the right elbow and nailfold infarcts (Fig 2). He was admitted for further investigation. His erythrocyte sedimentation rate in the first hour was 128 mm and ...

Objectives: There is a need to replace liver biopsy with non-invasive markers that predict the degree of liver fibrosis in fatty liver disease related to obesity. Therefore, we studied four potential serum markers of liver fibrosis and compared them with histopathological findings in liver biopsy in children with non-alcoholic fatty liver disease (NAFLD). Methods: We determined fasting serum level of hyaluronic acid (HA), laminin, YKL-40 and cytokeratin-18 M30 in 52 children (age range 4-19, mean 12 years, 80 % of them were overweight or obese) with biopsy-verified NAFLD. Viral hepatitis, autoimmune and metabolic liver diseases (Wilson's disease, alpha-1-antitrypsin deficiency, cystic fibrosis) were excluded. Fibrosis stage was assessed in a blinded fashion by one pathologist according to Kleiner. Receiver operating characteristics (ROC) analysis was used to calculate the power of the assays to detect liver fibrosis (AccuROC, Canada). Results: Liver fibrosis was diagnosed in 19 children (37 ...

Yesterday, a Congressional committee took an unprecedented step that limits access to innovative life-saving medications relied upon by thousands of patients living with rare diseases. The repeal of the Orphan Drug Tax Credit would have devastating effects for those facing chronic and genetic diseases, as it has proven to be essential to the development of hundreds of medicines, including plasma protein therapies.. Plasma protein therapies are life-saving treatments for persons facing particularly rare conditions, including Primary Immunodeficiency Diseases, Chronic Inflammatory Demyelinating Polyneuropathy, bleeding disorders such as Hemophilia, Hereditary Angioedema, and Alpha-1 Antitrypsin Deficiency. These are rare diseases as defined by the Food and Drug Administration (a condition which impacts fewer than 200,000 Americans), and the therapies which treat these diseases are considered "orphan drugs.". As tax reform efforts proceed, we encourage Members of Congress to stand with the ...
Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you. The results for both activity and antigen tests are given as percentages. Different labs use slightly different normal ranges, but in general, 80% to 120% is considered normal for adults. Newborns usually have about half as much antithrombin as adults. Thrombin levels in infants rise to adult levels by about 6 months of age.. People with genetically inherited antithrombin deficiency typically have test results between 40% and 60%.. In both type 1 and type 2 AT deficiency, the antithrombin activity test shows a low result because you dont have as much working antithrombin as you should have. When the AT activity test shows that levels are low, the antithrombin antigen test can then be used to find out whether the deficiency is type 1 or type 2.. If the follow-up ...
Mecamylamine has been used as a ganglionic blocker in treating hypertension, but, like most ganglionic blockers, it is more often used now as a research tool.. Mecamylamine is also sometimes used as an anti-addictive drug to help people stop smoking tobacco,[2] and is now more widely used for this application than it is for lowering blood pressure. This effect is thought to be due to its blocking α3β4 nicotinic receptors in the brain.. In a recent double-blind, placebo-controlled Phase II trial in Indian patients with major depression, (S)-mecamylamine (TC-5214) appeared to have efficacy as an augmentation therapy. This is the first substantive evidence that shows that compounds where the primary pharmacology is antagonism to neuronal nicotinic receptors will have antidepressant properties.[3][4] TC-5214 is currently in Phase III of clinical development as an add-on treatment and on stage II as a monotherapy treatment for major depression. The first results reported from the Phase III trials ...
