Determination of Helicobacter pylori virulence-associated genes in duodenal ulcer and gastric biopsies
Background: Helicobacter pylori (H. pylori or Hp) has been strongly associated with the peptic ulcer diseases, chronic gastritis, ulcers, and gastric cancer. Genes associated with pathogenicity have been designated for H. pylori, and some of them appear to be related to more severe clinical consequences of the infection. The present study was conducted to determine cagA, vacA, cagE, iceA1, oipA...
متن کاملRole of autophagy associated with Helicobacter pylori CagA and VacA toxins in gastric cancer
Helicobacter pylori (H. pylori) is a gram-negative microaerophilic bacterium that has been introduced as a cause of mucosal inflammation and gastric cancer. The most important pathogenic factors are VacA and CagA, which are associated with increased disease severity in clinical strains. Autophagy is a protected lysosomal degradation pathway degrading cytoplasmic content and is important in host...
متن کاملAge at Establishment of Helicobacter pylori Infection and Gastric Carcinoma, Gastric Ulcer, and Duodenal Ulcer Risk1
Helicobacter pylori is an important risk factor for gastric cancer, gastric ulcer, and duodenal ulcer, yet most infected persons do not develop disease. We examined two correlates of acquisition age, sibship size and birth order, to evaluate the hypothesis that early life acquisition of //. pylori is a risk factor for the development of these illnesses. In earlier nested case-control studies of...

متن کاملHelicobacter pylori and associated duodenal ulcer.
Twenty three children with coexistent duodenal ulcer and Helicobacter pylori infection were treated with either two weeks of amoxycillin (25 mg/kg/day) in addition to six weeks of cimetidine, or cimetidine alone. Endoscopy with antral and duodenal biopsies for urease test, microaerophilic culture, and histological studies were performed at entry, six weeks, 12 weeks, and at six months. Children...
