Antitripsine

Alpha-1 antitrypsin (A1AT) deficiency is one of the most common genetic disorders in Caucasian population. There is a link between granulomatosis with polyangiitis (GPA) and most frequent variants of SERPINA1 gene encoding severe alpha-1 antitripsin deficiency. However, the potential effect of Pi*Z, Pi*S as well as other SERPINA1 variants on clinical course of vasculitis are not well understood. The aim of the study was to analyze the potential effect of A1AT protein phenotype representing the SERPINA1 gene variants on the clinical course of GPA...

OBJECTIVES: The study was aimed to assess the influence of tobacco smoke exposure on the intensity of inflammation measured by IL-6, α 1 -antitripsin (AAT) and α 1 -acid glycoprotein (AGP) concentrations, and Cd level and oxidative stress intensity measured by advanced oxidation protein product (AOPP) concentration in the blood of healthy subjects and AP patients during hospitalization. Endothelin-1 (ET-1) and resistin concentrations, markers of endothelium injury, were determined. RESULTS: An increased IL-6 concentration in healthy smokers compared to nonsmokers and AP patients compared to controls was shown...

Western blot of synovial fluid has been widely used for osteoarthritis (OA) research and diagnosis, but there is no ideal loading control for this purpose. Although β-actin is extensively used as loading control in western blot, it is not suitable for synovial fluid because it is not required in synovial fluid as a cytoskeletal protein. A good loading control for synovial fluid in OA studies should have unchanged content in synovial fluids from normal and OA groups, because synovial fluid protein content can vary with changes in synovial vascular permeability with OA onset...

Protein-loosing enteropathy in patients with inflammatory bowel diseases (IBDs) is an uncommon complication, but should be considered in any patient with hypoproteinemia in whom other causes have been excluded such as concomitant hepatic disease, severe malnutrition or proteinuria. The diagnosis is based on determination of fecal alpha-1 antitripsin clearance and stool analysis. Prognosis depends upon the patient and the disease location, severity and complication. Treatment is directed at control of the underlying IBDs but also includes albumin infusion in the most severe cases of hypoalbuminemia and fluid retention, dietary modifications for recovery and maintenance of nutritional status and supportive care to prevent further complication like deep venous thrombosis...

BACKGROUND & AIMS: Wilson's disease (WD) is an autosomal recessively inherited copper storage disorder due to mutations in the ATP7B gene that causes hepatic and neurologic symptoms. Current treatments are based on lifelong copper chelating drugs and zinc salts, which may cause side effects and do not restore normal copper metabolism. In this work we assessed the efficacy of gene therapy to treat this condition. METHODS: We transduced the liver of the Atp7b(-/-) WD mouse model with an adeno-associated vector serotype 8 (AAV8) encoding the human ATP7B cDNA placed under the control of the liver-specific α1-antitrypsin promoter (AAV8-AAT-ATP7B)...

INTRODUCTION: The low-grade inflammation and insulin resistance are two events that could be present in varying degrees, on obesity and chronic diseases. The degree of subclinical inflammation can be gauged by measuring the concentrations of some inflammatory biomarkers, including the hepatic origin ones. Some of those biomarkers are sialic acid, α1-antitrypsin and the C-terminal fragment of alpha1-antitrypsin, ceruloplasmin, fibrinogen, haptoglobin, homocystein and plasminogen activator inhibitor-1...

The comprehensive biochemical examination of 62 children aged from 1.5 months to 2 years old with diagnosis of neonatal hepatitis. The changes of standard indicators of cytolysis, cholestasis and protein metabolism were on average moderate in group with reliable increase of protein concentration of acute phase of inflammation...

The integral indices based on element ratio of hemogram as well as alpha-1 antitripsin, interleukins 2 and 10 contents in the adolescents living in industrial town with a high pollution level are represented in this paper. The increase in the processes of the nonspecific phagocytic protection and exertion of adaptive mechanisms has been revealed.

We delineate a complication of hypoalbuminemia in dentatorubral-pallidoluysian atrophy (DRPLA), which we have found to be common in this disorder. In addition, we explored the pathogenesis of this phenomenon through clinical and histological examinations. Clinical course and laboratory findings of nine patients with childhood-onset DRPLA (aged 6-49 years; CAG repeat length 62-93) were retrospectively reviewed. Autopsied specimens from three patients were examined by histopathological and immunohistochemical analyses...

The content of alpha-macroglobulin associated with pregnancy, alpha2-glycoprotein, alpha1-antitripsin, and lactolerrin in blood serum of pregnant women and umbilical serum under hydramnion and risk of development of intrauterine infection of fetus is investigated. It is demonstrated that in case ofpresence in blood of pregnant woman of G-antibodies to C. trachomatis under low titers (1:20, 1:40) the increase of levels of alpha-macroglobulin, alpha2-glycoprotein, al-antitripsin and especially of lactoferrin in serum of pregnant women testifies the high risk of presence of intrauterine infection of fetus and probability of birth of child with low values on Apgar scale...

This article presence the connection between paradontitis and cardiovascular diseases, and definition of the maintenance of acute phase proteins in an oral fluid at patients with acute myocardial infarction is obviously important for clinic. Results of own researches of change of the maintenance of three acute phase proteins: ceruloplasmin, alpha1-antitripsin and orosomucoid in an oral fluid and blood plasma at paradontitis and myocardial infarction allow to consider the paradontitis as one more risk factor of a cardiovascular pathology, except well-known hypertensions, smoking, a diabetes...

The article presents the results of analysis of blood serum from 60 patients (aged 58.9 +/- 1.5 years) with Q-genous complicated and non-complicated cardiac infarction. The study evaluated the content of various proteins of acute phase (alpha-2-macrogloblin, alpha-1-antitripsin. lactofferin) and cytokines inducing their synthesis (IL-6, IL-1beta, L-8).

Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death worldwide. Primary hepatocellular carcinoma can be found most frequently (80-90 %) in patients with liver cirrhosis. The most frequent causes of liver cirrhosis are chronic hepatitis B and C virus infections and chronic alcohol consumption. The occurrence of hepatocellular carcinoma is about 3-15 % in patients with alcoholic liver disease. Other predisposing causes can be: non-alcoholic steatohepatitis (NASH), obesity, diabetes mellitus, autoimmune hepatitis, intrahepatic biliary inflammations (primary biliary cirrhosis, primary sclerosing cholangitis), copper and iron metabolic diseases (Wilson-disease, haemochromatosis), congenital alpha-1-antitripsin deficiency...

UNLABELLED: Obesity is associated with increased inflammation. Creactive protein (CRP) and inflammation-sensitive plasma protein (ISPs) are inflammatory markers. Proinflammatory process may be influenced by high saturated fatty acid intake. OBJECTIVE: The aim of the present study was to evaluate the role of saturated fatty acids load on postprandial circulating levels of PCR and ISPs (alpha1-antitrypsin, alpha1-acid glucoprotein, and fibrinogen) in obese women. DESIGN: A total of 15 obese women (age = 31,7 +/- 4,5 years, BMI = 37,9 +/- 7,3 kg/m(2)) and 15 lean controls women (age = 30,6 +/- 4,6 years, BMI = 20,6 +/- 2,6 kg/m(2)) were recruited for this study...
