Foods with animal origins play a substantial role in the transmission of Helicobacter pylori. The present investigation was carried out to study the vacA and cagA genotypes status of H. pylori isolated from various types of meat samples. Two hundred and twenty meat samples were collected and cultured. H. pylori-positive strains were analyzed for the ...

Background: Until now, no study has been reported investigating the association between β-thalassemia minor and Helicobacter pylori (H. pylori) infection. This study was designed to compare H. pylori infection rate between β-thalassemia minor patients and healthy controls. Methods: A number of 100 β-thalassemia minor patients (50 males, 50 females) and 100 gender-matched healthy...

Introduction: Helicobacter pylori (H. pylori) is suggested to play a role in dyspepsia. The aim of this study was to assess the prevalence of H. pylori, in dyspeptic patients. Methods: This cross-sectional study was conducted on 850 patients with dyspepsia in Iran (2006-2007). The patients were selected using convenience sampling method. Data was collected using ROME III criteria questionnaire...

OBJECTIVE To determine the association of Helicobacter pylori infection in patients presenting with idiopathic thrombocytopenic purpura (ITP). METHODS From March 2007 to March 2008, thirty adult patients with ITP and 30 age and sex matched healthy controls were investigated for the presence of H. pylori infection by Helicobacter pylori stool antigen (HpSA) an enzyme immunoassay (EIA) based me...

Pediatric infection with Helicobacter pylori may occur early in childhood and persist lifelong. Global pediatric clinical studies have reported a decreasing tendency in the overall rate of H. pylori eradication. In pediatric patients with H. pylori infection, pediatric patients with peptic ulcer, and the first-degree relatives of patients with a history of gastric cancer, it is commonly recomme...

The aim of this study was to determine the prevalence of Helicobacter pylori among children and their family members and to evaluate some epidemiologic characteristics. The study included 275 children, aged 1-15 year(s), suffering from different gastrointestinal complaints. Blood serology and stool antigen testing were used for the diagnosis of infection due to H. pylori. Sixty-five (23.6%) of ...

conclusions we found considerable relationship between s1a/m1a, s1a/m2, s2/m2 and s1c/m1a and some gastric disorders. further studies about the role of h. pylori virulence factors and gastric disorders were recommended. results the frequency of the vaca genotypes, sa1/m1, s1a/m1b, s1a/m2, s1b/m1a, s1b/m1b, s1b/m2, s1c/m1a, s1c/m1b, s1c/m2, s2/m1a, s2/m1b and s2/m2 were 27(6.6%), 8(4.3%), 45(28....

H. pylori persists in the human stomach over decades and promotes several adverse clinical sequelae including gastritis, peptic ulcers and gastric cancer that are linked to the induction and subsequent evasion of chronic gastric inflammation. Emerging evidence indicates that H. pylori infection may also protect against asthma and some other immune-mediated conditions through regulatory T cell e...

BACKGROUND Helicobacer pylori infection is a major gastric cancer risk factor. Deficient DNA mismatch repair (MMR) caused by H. pylori may underlie microsatellite instability (MSI) in the gastric epithelium and may represent a major mechanism of mutation accumulation in the gastric mucosa during the early stages of H. pylori-associated gastric carcinogenesis. In this study, we examined the expr...

The present study was designed to explore the existence of oral Helicobacter pylori (H. pylori), its relationship in the oral cavity to the success rate of eradication of the gastric H. pylori infection, and to determine if the mouthwash solution contained lysine (0.4%) and glycerol monolaurate (0.2%) (LGM) could eliminate oral H. pylori, as well as using the saliva H. pylori culture to confirm...
