conclusions the distribution patterns of phase-variable genes in pakistani h. pylori strains were found to be somewhat different. the dominant prevalence of the hsdr gene was an interesting finding, considering its role in bacterial defense in both micro- and macroenvironments. results on culturing, the prevalence of h. pylori infections in the samples was 44.7%. the prevalence was higher in fe...

Background and purpose: Helicobacter pylori, which infect approximately one half of the world’s population, are an important risk factor in chronic gastritis, peptic ulcer disease, and gastric cancer. H. pylori eradication is now widely recommended as the most effective treatment of peptic ulcer disease. One of the most important reasons for treatment failure is H. pylori resistance to the anti...

Background Non-Steroidal Anti-Inflammatory Drugs(NSAIDs) including Ibuprofen is one of the most currently used drugs in all age groups and finding the relation between upper gastrointestinal bleeding and Helicobacter pylori (H. pylori) in children who used Ibuprofen, is our topic of research. Materials and Methods During the two years of the study, ten children with upper GI bleeding after Ibup...

Reports from countries with a high prevalence of Helicobacter pylori (H pylori) infection do not show a proportionately high prevalence of duodenal ulceration, suggesting the possibility that H pylori cannot be a primary cause of duodenal ulceration. It has been mooted that this discrepancy might be explained by variations in the prevalence of virulence factors in different populations. The aim...

Introduction & Objective: Different studies show that the reasons for clinically diverse outcomes of infections caused by H. pylori may include host and environmental factors as well as differences in the prevalence or expression of bacterial virulence factors. The aim of this study was to study the distribution of different genotypes of major virulence factors cagA, vacA and ureAB among H. p...

Background: Previous studies imply that IL-1 and IL-8 gene variations may play a crucial role in the genetic predisposition to different gastric disorders upon H. pylori infection. Objective: The aim of this study was to determine the potential association between the prevalence of certain polymorphic sites and the risk of gastric disorders in Iranian population. Methods: One hundred and forty ...

BACKGROUND Helicobacter pylori infection affects more than half of the world's population. It is generally acquired during childhood with no symptoms but has long- term clinical sequelae. This study estimated the prevalence of H. pylori infection amongst children in a rural environment in Africa. METHODS We conducted a cross-sectional study over a four (4)-month period within two rural commun...

At an individual level Helicobacter pylori was associated with the occurrence of gastric cancer but in some African and Asian countries its prevalence runs with low gastric cancer rates, the so-called African and Asian enigmas. We assessed whether the association between gastric cancer and H. pylori prevalence at an area level is modified by the level of exposure to fruits and vegetables, alcoh...

The prevalence of Helicobacter pylori is increased in healthcare workers and in intensive care nurses. Exposure to H. pylori from gastric secretions and faeces are probably the main sources of transmission to healthcare workers. Routine use of selective decontamination of digestive tract (SDD) in an intensive care unit suppresses H. pylori in critically ill patients. It was questioned whether t...

Helicobacter pylori remains a challenging worldwide medical problem due to its extreme widespread prevalence and its close relation to acid peptic disease, gastric carcinoma and lymphoma. All these reasons made the medical world believe that H. pylori eradication should be a necessary attempt [1,2]. The last three decades have shown prevalence of abnormal-behavior H. pylori strains and the risi...
