Russell body gastritis is a rare form of chronic gastritis. It is characterized by the invasion of lamina propria by plasma cells that included eosinophilic cytoplasmic inclusion. In the literature, most of the cases are associated with Helicobacter pylori. Russell body gastritis and Helicobacter pylori infection are generally seen together incidentally. We report here two cases of Russell body...
Helicobacter pylori (H. pylori) is the causative agent in development of gastroduode-nal diseases, such as chronic atrophic gastritis, peptic ulcers, mucosa associated lym-phoid tissue (MALT) lymphoma, and gastric cancer. H. pylori has been associated with inflammation in cardia, showing the fact that infection with this bacterium could also be a risk factor for gastric cardia cancer. Gastric c...
Abstract Helicobacter pylori is the major etiological agent for most gastric cancer. CagA has been reported to be an important virulence factor of H. pylori, but its effect on immune response not yet clear. In this study, wild-type C57BL/6 mice and Ptpn6me-v/me-v were randomly assigned infection with pylori. We demonstrated that suppressed pylori–stimulated expression proinflammatory cytokines ...
Background: Attempts for early detection of gastric cancer have recently focused on host's genetic susceptibility factors and gene-environment interactions. We have, herein, studied the association of MTHFR C677T single nucleotide polymorphism (SNP) and its interaction with Helicobacter pylori infection, smoking, age and gender on the risk of gastric cancer among an Iranian population. Methods:...
Background: The prevalence of Helicobacter pylori (H. pylori) infection in patients with rosacea is reported from 50 to 90 percent, which suggests the possibility of the role of this organism in pathogenesis of rosacea. Objectives: Evaluation of relationship between H. pylori infection and rosacea. Patients and Methods: In this case-control study, 30 patients referred to skin clinics of B...
BACKGROUND Some previously published studies have suggested an inverse relationship between celiac disease and Helicobacter pylori, raising the possibility of the protective role Helicobacter pylori could have against celiac disease development. Nevertheless, this association is inconclusive. OBJECTIVES To determine the prevalence of Helicobacter pylori infection in celiac subjects. METHODS...
h.pylori is one of the common infectious agent that involves in acute and chronic gastritis, peptic scar and gastric cancer. the infection episode in children ranges between 10 to 80 percent and the high frequency in developing countries. the goal of this study was to determine the incident of h.pylori in the patients carried out to endoscopy and the effective factors. in this study, 50 patient...
conclusions in conclusion, these results suggested a need for a switch to second line therapy regimens for treatment of infected patients in the iranian population. results helicobacter pylori infection was detected in 22 patients (22.92%). identity of the isolates was confirmed by pcr using glmm primers. chronic gastritis, duodenitis, intestinal metaplasia, dysplasia and cancer were detected a...
background although infection with helicobacter pylori is a global health problem, its prevalence is different among countries. serologic tests for the diagnosis of h. pylori infection are limited by low accuracy rates and lack of validation. recent studies indicate that the stool antigen test has an acceptable level of accuracy. objectives our objective was to investigate the prevalence of h. ...
The pathogenic bacterium Helicobacter pylori is a causative agent of gastric diseases in Bangladesh as well as throughout the world. This study aimed at analyzing the prevalence of H. pylori infection among dyspeptic patients in Chittagong, the second most populous city of Bangladesh, using 16S rRNA-based H. pylori-specific Polymerase Chain Reaction and Campylobacter-like organism test. We foun...
