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...

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...

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 and aims: helicobacter pylori (h. pylori) is the microorganism that infects nearly half of word's population. there are several invasive and non-invasive methods for diagnosis of infection. the main objective of this study was to evaluate antigen of h. pylori in feces with h. pylori stool antigen (hpsa) test and comparison with rapid urease test (rut) in the patients suspected t...

development of a stool antigen immunoassay to detect helicobacter pylori infection requires monoclonal antibody against the specific antigen. alkylhydroperoxide reductase (ahpc) of helicobacter pylori has been described as a specific and unique enzyme for h. pylori and therefore, both h. pylori ahpc and anti-ahpc could be useful in the development of serologic and stool antigen tests, for detec...

BACKGROUND A diagnosis of H. pylori infection can be made by invasive or non-invasive methods. Several noninvasive diagnostic tests based on the detection of H. pylori stool antigen (HpSA) have been developed. The Genx H. pylori stool antigen card test is a new rapid, non-invasive test that is based on monoclonal immunochromatographic assay. The aim of this study was to determine its sensitivit...

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...

OBJECTIVE To compare the presence of Helicobacter pylori (H. pylori) infection by stool antigen test in children with and without halitosis. STUDY DESIGN Comparative study. PLACE AND DURATION OF STUDY Department of Paediatrics, Fatih University Hospital, Ankara, Turkey, between December 2008 and June 2009. METHODOLOGY Fifty-three patients aged between 3-15 years who presented to paediatri...

Background: Asthma is a highly prevalent chronic respiratory disease in children. Moreover, the underlying causes of asthma exacerbation are important because they are effective in controlling and preventing asthma. The aim of this study was to evaluate the helicobacter pylori infection in controlled and uncontrolled asthmatic children compared to healthy children. Methods: This case- contro...
