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 antigen...

Helicobacter pylori infections are accompanied with the release of some antigenic material into the stool. Outer membranes proteins (OMP) are among the major antigens of bacteria, which in comparison with other bacterial constituents have less cross-reactivity. In this study, OMP of H. pylori were isolated from 11 clinical isolates and rabbit antiserum against them was used to detect possible a...

BACKGROUND Recent availability of tests for Helicobacter pylori antigens in stool samples has provided potentially useful tools for epidemiological studies and clinical settings. The aim of this study was to evaluate a monoclonal antibody-based H. pylori antigen stool test in the primary diagnosis of H. pylori infection, and to study the test performance after patients were treated with lanzopr...

background: some antigens of h. pylori are excreted into the stool of infected people. these antigens can be used to detect the infection by immunoassays such as elisa. our aim was to identify these antigens by immunoblotting and affinity chromatography techniques.   methods: four different antigenic preparations, namely, whole cell sonicate (wcs), outer membrane proteins (omps), cytoplasmic an...

Evidences supporting the association between H. pylori infection and chronic cholecystitis could be found by using direct culture or staining of H. pylori in gallbladder tissues as well as indirect techniques. Stool antigen test has been widely used due to its noninvasive nature. Various stool antigen tests were developed to detect H. pylori using an enzyme immunoassay (EIA) based on monoclonal...

BACKGROUND Helicobacter pylori infection is etiologically associated with some important health problems such as gastric cancer. Because of the high clinical importance of H. pylori infection, development of a noninvasive test for the detection of H. pylori is desirable. METHODS In this study, a loop-mediated isothermal amplification (LAMP) targeted ureC of H. pylori was evaluated on 100 stoo...

conclusions the most important factor in childhood acute gastroenteritis in east anatolia is the rotavirus. rotavirus and adenovirus antigens should be routinely investigated as a factor in fresh stool samples for the accurate diagnosis and treatment of gastroenteritis in children in the winter and autumn months. patients and methods the records of stool sample analyses for 1154 patients admitt...

conclusions: the result of our study showed that using clarithromycin, amoxicillin and omeprazole for treatment of h. pylori infection can be useful. it is concluded from lower levels of igg and caga in blood and h. pylori antigen in stool after treatment compared to the amount of these factors before therapy. considering all these data, it is obvious that there is an urgent need to found a bet...
