Association of presence/absence and on/off patterns of Helicobacter pylori oipA gene with peptic ulcer disease and gastric cancer risks: a meta-analysis
BACKGROUND There are increasing studies examining the relationship between the status of H. pylori oipA gene and peptic ulcer disease (PUD) and gastric cancer (GC) but the results turn out to be controversial. We attempted to clarify whether oipA gene status is linked with PUD and/or GC risks. METHODS A systematically literature search was performed through four electronic databases. Accordin...
متن کاملRelevance of Helicobacter pylori dupA and OipA genotypes and development of gastric disease
Helicobacter pylori infection is now accepted as the major cause of severe gastritis-associated diseases, including peptic ulcer and gastric cancer. In the current study, we decided to determine the dupA and OipA genotypes in H. pylori strains isolated from patients with gastrointestinal disorders and to evaluate whether these genes are associated with the severity of the gastroduodenal disease...
متن کاملTHE ASSOCIATION OF CAMPYLOBACTER PYLORI (HELICOBACTER PYLORI) WITH GASTRITIS AND PEPTIC ULCER
We studied the relationship between gastroduodenal inflammation and the presence of Campylobaeter pylori from biopsy specimens of the gastric mucosa in 91 patients with gastritis with or without ulcers and 9 controls, healthy or suffering from other diseases. 68 of the patients were positive for the presence of C. pylori in their gastric mucosa. C. pylori was confirmed bacteriohistological...
متن کاملPrevalence of Pathogenic Genes cagA and vacA of Helicobacter pylori Isolated in Patients with Digestive Disorders
Background and Aims: Helicobacter pylori is the main cause of various gastroduodenal diseases. It is estimated that app roximately, more than half of the adult population in developed countries and 90% of people in developing countries infected with H. pylori. H. pylori infection may be related to Genetic of virulence factors and environmental factors. The aim of this study was to assess of fre...
متن کاملEvaluation of frequency polymorphism Interleukin 1B gene in patients with peptic ulcer and chronic gastritis
Introduction: Helicobacter pylori is the main cause of chronic inflammation and peptic ulcer. More than half of the world population is afflicted with Helicobacter, while only 20% of people show the clinical symptoms of the disease. Genes encoding the cytokines interleukin (IL)-1B play a key role in the inflammatory responses of gastric mucus. This study aims to analyze polymorphism in the IL-1...
