alkylhydroperoxide reductase (ahpc, the 26 kda antigen) is one of the abundant antioxidant enzymes in helicobacter pylori and seems to have a good potential for use in development of immunoassays to detect h. pylori infection in clinical specimens. this study aimed to investigate some properties of this antigen by the produced monoclonal antibodies. five established hybridoma cell lines secreti...
INTRODUCTION Chronic urticaria (CU) is defined as the presence of urticaria on most days of the week for a period of 6 weeks or longer. Some studies have reported an association between CU and Helicobacter pylori (H. pylori) infection. AIM To determine the prevalence of H. pylori infection using the stool antigen test in patients with idiopathic CU and to investigate the infected patients wit...
Introduction: Helicobacter pylori (H. pylori) is an important bacterial pathogen, predominantly in undeveloped countries and regions. We conducted this study to investigate the presence of H. pylori antigen in the stool specimens of children, in Tekirdag, Turkey. Material and Methods: Stool specimens of 1441 children aging between 0 month to 15 years, with the complaints of abdominal pain, anem...
Background Helicobacter pylori antibody titters fall very slowly even after successful treatment. Therefore, tests detecting H. pylori antibody lack specificity and sensitivity. On the other hand, H. pylori stool antigen tests are reported as an alternative assay because of their reliability and simplicity. However, the comparative performance of H. pylori stool antigen tests for detecting the ...
OBJECTIVE Highly sensitive guaiac-based faecal occult blood (Hemoccult SENSA) and Helicobacter pylori stool antigen testing might help detect upper gastrointestinal lesions when appended to a colorectal cancer screening programme with faecal immunochemical testing. We evaluated the diagnostic accuracies of two stool tests in detecting upper gastrointestinal lesions. DESIGN Cross-sectional des...
h. pylori infection is usually acquired in early childhood. its role in gastrointestinal and extra intestinal complaints and serious consequences in adulthood make it as challenging issues. despite different clinical presentations, in most children, the presence of h. pylori infection does not lead to clinically apparent disease, even when it causes chronic active gastritis. some of most import...
background and objectives: invasive and non-invasive techniques are used to diagnose h. pylori infection. some factors influence the choice of a diagnostic test, such as the sensitivity and specificity of the tests, the clinical circumstances and the cost-effectiveness of the testing strategy. the aim of this study was to reveal the relationship between different h. pylori infection diagnosis m...
Introduction: Helicobacter pylori infection has various clinical features. One of the most common presentations of this infection is upper abdominal pain. Complications such as gastritis, gastric ulcer, gastric carcinoma and MALT lymphoma mandate early diagnosis of H.P infection by a low cost and non invasive manner. The aim of this study was to evaluate the diagnostic role of H.P stool antige...
background: helicobacter pylori is the most common cause of chronic infection in the human stomach. the infection has universe prevalence in all age groups. probably, this bacterium is the cause of most common chronic bacterial infection in human beings and infects approximately half of the world population. h. pylori produces urease, an enzyme that degrades the urea in the stomach’s mucous to ...
conclusions based on the findings, application of recombinant arcaga antigen for the detection of h. pylori infection is a simple, rapid, and brief non-invasive method. therefore, it can be suggested as an appropriate antigen for h. pylori detection kits. results we investigated caga protein, using the immunoblotting method in stool samples, which were already identified as positive by the appl...
