Gastric epithelial chemokine response is a primary factor in the induction of gastric inflammation associated with Helicobacter pylori infection. Because sustained inflammation is a risk for gastric mucosal damage, agents that down-regulate inflammatory responses may be of therapeutic significance. We examined the effect of polaprezinc, a potent antiulcer agent, on proinflammatory cytokine-indu...
BACKGROUND The aim of this study was to investigate the effect of N-methyl-N-nitrosourea (MNU) treatment followed by chronic Helicobacter pylori SS1 and H. felis colonization on the stomachs of C57BL/6 mice. The role of MNU and Helicobacter species in gastric carcinogenesis was also elucidated. METHODS A total of 69 C57BL/6 mice at 4 weeks of age were divided into 6 groups according to MNU tr...
The gastric mucosal immune response is thought to be comprised predominantly of the Th1 type; however, there are limited data regarding the role of IL-18 in Helicobacter pylori-induced inflammation. We investigated IL-18 levels in gastric mucosal biopsy specimens as well as in isolated gastric epithelial cells and lamina propria mononuclear cells. We also investigated IL-18 levels in gastric ep...
Infection with Helicobacter pylori, carrying a functional cag type IV secretion system (cag-T4SS) to inject the Cytotoxin associated antigen (CagA) into gastric cells, is associated with an increased risk for severe gastric diseases in humans. Here we studied the pathomechanism of H. pylori and the role of the cag-pathogenicity island (cag-PAI) for the induction of gastric ulcer and precancerou...
objective: helicobacter pylori is a spiral, microaerophilic gram negative bacterium, that multiplies and causes infection in human gastric mucosal layer. h.pylori infection, followed by destruction of gastric epithelial tissue, leads to gastric chronic inflammation, which can cause gastric and peptic ulcers. new approaches have focused on using specific treatments, such as immunotherapy, to era...
Levofloxacin-Dexlansoprazole Based Quadruple Therapy for Helicobacter Pylori Eradication in Thailand
Helicobacter pylori (H. pylori), a gram-negative bacterium found on the luminal surface of the gastric epithelium, was first isolated in 1984 (Marshall and Warren, 1984). It induces chronic inflammation of the underlying mucosa resulting in the development of important upper gastrointestinal diseases such as gastritis, peptic ulcer diseases, mucosa-associated lymphoid tissue (MALT) lymphoma, an...
OBJECTIVE Both variations in the interleukin-10 (IL10) gene and environmental factors are thought to influence inflammation and gastric carcinogenesis. Therefore, we investigated the associations between IL10 polymorphisms, Helicobacter pylori (H. pylori) infection, and smoking in noncardia gastric carcinogenesis in Koreans. METHODS We genotyped three promoter polymorphisms (-1082A>G, -819T>C...
Family relatives of gastric cancer patients have a higher risk of gastric cancer and premalignant gastric lesions. We sought to determine the risk factors associated with the presence of intestinal metaplasia in a large cohort of gastric cancer relatives. First-degree relatives of gastric cancer patients were invited for screening gastroscopy. Endoscopic gastric biopsies were obtained from the ...
Heterotopic pancreas (HP) is a rare entity which is defined as the presence of pancreatic tissue lacking anatomical and vascular continuity with the pancreas. It is most commonly found along foregut derivatives, such as the stomach, duodenum, and jejunum. It is frequently encountered incidentally in asymptomatic patients, and symptomatic patients are rare and do not exhibit any specific symptom...
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...
