micronutrients: a double-edged sword in microbe-induced gastric carcinogenesis.epidemiologic studies throughout the world have uniformly demonstrated significant relationships between the intake of dietary micronutrients and gastric cancer risk. an exciting concept that has recently gained considerable traction is that micronutrients modulate gene expression within helicobacter pylori, the strongest identified risk factor for gastric carcinogenesis. we present evidence here that essential micronutrients have a direct effect on h. pylori virulence, which subsequently affect ...201528741523
[helicobacter pylori infection and extragastroduodenal diseases].at present, the clinical significance of helicobacter pylori infection has been validly determined within the development of a diversity of gastroduodenal diseases, including chronic gastritis, gastroduodenal ulcer, malt lymphoma, and gastric adenocarcinoma. the expert council's maastricht iv consensus (2010) determining international standards for the diagnosis and treatment of h. pylori infection is that there is evidence that the latter may be associated with the development of a number of ex ...201528635878
current knowledge on alleviating helicobacter pylori infections through the use of some commonly known natural products: bench to bedside.helicobacter pylori, a spiral-shaped gram-negative bacterium, has been classified as a class i carcinogen by the world health organization and recognized as the causative agent for peptic ulcers, duodenal ulcer, gastritis, mucosa-associated lymphoid tissue lymphomas, and gastric cancer. owing to their alarming rate of drug resistance, eradication of h. pylori remains a global challenge. triple therapy consisting of a proton pump inhibitor, clarithromycin, and either amoxicillin or metronidazole, ...201428664086
aggressive helicobacter pylori-negative peptic ulceration as the initial manifestation of crohn's disease.peptic ulceration is a recognised feature of crohn's disease, but the characteristics of this manifestation are rather poorly described. furthermore, most reports in the literature relate to ulcer disease in cases of established crohn's disease. the authors report a series of four cases in which the diagnosis of crohn's disease was preceded by peptic ulceration. potential confounding factors were as far as possible excluded, implying a true association. characteristics of the ulcer disease inclu ...201228839665

tumour necrosis factor alpha antibody affects gastrin release in crohn disease.gastrin plays an important role in the regulation of gastric acid secretion in humans. tumour necrosis factor alpha (tnf-α) stimulates gastrin release from antral g cells in vitro. the aim was to determine whether gastrin release decreases in patients with crohn disease treated with monoclonal antibody to tnf-α.200328443771
comparison of gastric histology among swedish and japanese patients with peptic ulcer and <emph type="2">helicobacter pylori</emph> infection.the natural course of helicobacter pylori gastritis may vary between different ethnic groups. gastric histopathology and the occurrence of h. pylori organisms in the stomach were investigated in healed duodenal (du) and gastric (gu) ulcer patients recruited in sweden (s) and japan (j) in an identical trial.200328443767
helicobacter pylori and gastric cancer: is there a link?this paper examines the correlation between prevalence of h pylori, gastritis and the histological type of gastric cancer. 50 gastrectomy specimens from the patients with gastric cancers were studied for the prevalence of h pylori, type of gastritis as classified by the sydney system, presence of intestinal metaplasia, and the histological type of gastric cancer. h pylori was detected in 27 (54%) stomachs. the common site for finding this bacterium was either antrum or body of stomach (16 and 17 ...199828775514
