AIM The premier platinum Helicobacter pylori (H pylori) stool antigen (HpSA) test is an enzyme immunoassay (EIA) that detects an H pylori antigen present in human stools. However, at present there is no uniformity about the cut off level required to consider the test as positive or negative. So we need the cut off level for our local population. The aim of this study was to evaluate the HpSA fo...

Background: Reliable non-invasive methods for detection of Helicobacter pylori infection are required to investigate the incidence, transmission, and clearance of infection in childhood. Aim: To evaluate a new monoclonal enzyme immunoassay (EIA) (FemtoLab H pylori Cnx) for detection of H pylori antigen in stool in a large cohort of children compared with invasive diagnostic methods and the C ur...

A highly sensitive seminested PCR assay to detect Helicobacter pylori DNA in feces was developed. PCR with stool specimens and a novel antigen enzyme immunoassay (EIA) for H. pylori detection in feces were evaluated as diagnostic tools and in follow-up with samples from 63 infected and 37 noninfected persons. Infected individuals received eradication therapy followed by endoscopic follow-up 35 ...

A comparative cross-sectional study was conducted on 60 sewage workers and 30 matched unexposed referents from Mansoura city, Egypt, to estimate the prevalence and risk factors of Helicobacter pylori (H. pylori). Stool culture and detection of H. pylori antigen were done. In addition, the polymerase chain reaction (PCR) amplification of cytotoxin-associated gene A (cagA) gene in H. pylori in st...

Background: Helicobacter pylori (H. pylori) is a worldwide gastrointestinal infection. It common risk factor for peptic ulcer disease (PUD), chronic gastritis, and stomach cancer. In patients with cirrhosis, there significant association between H. infection severity of gastropathy due to portal hypertension, upset, frequent upper bleeding as well hepatic encephalopathy. Objective: To assess t...

Some Lactobacillus spp. suppress Helicobacter pylori in the stomach and have potential therapeutic applications for the treatment of gastrointestinal conditions. In this study, the effects of Lactobacillus strains on functional dyspepsia associated with H. pylori infection were examined. Volunteers were screened using the (13)C-urea breath test (UBT) and H. pylori stool test, and 131 participan...

A test using monoclonal antibodies for detection of antigen in stool samples was compared with culture and histology for noninfected (n = 25), Helicobacter pylori-infected (n = 25), and Helicobacter felis-infected (n = 6) mice. Sensitivity and specificity were 96%. The monoclonal antibody-based test is therefore a noninvasive technique that is able to diagnose H. pylori infection in mice.

Background: Smoking is hazardous to almost any organ in the body and has a harmful effect on gastric mucosa. Objective: The main goal of this study was evaluate synergistic smoking H. pylori infection mucosal among dyspeptic Egyptian patients. Patients Methods: A cross-sectional conducted 240 consecutive patients with dyspepsia who underwent upper endoscopy histopathological examination biopsie...
