The new Maastricht VI/Florence Consensus clarifies a number of provisions that were previously under discussion. It has been postulated Helicobacter pylori infection always causes gastritis, regardless symptoms or complications. Before making convincing diagnosis functional dyspepsia, it is necessary to exclude Helicobacters gastritis. Some the consensus, such as test and treat tactic, require ...

INTRODUCTION Chronic atrophic gastritis, intestinal metaplasia, hereditary non-polyposos colon cancer, gastric dysplasia, gastric adenoma, Barrett esophagitis and familiar adenomatous polyposis are confirmed precancerous lesions of the stomach. Most of these conditions are correlated with long-term infections with Helicobacter pylori. MATERIAL AND METHOD Patients which were included in our st...

BACKGROUND/AIMS Helicobacter pylori-associated corpus atrophy and autoimmune gastric atrophy share similar histopathologic and clinical aspects. In our study, the relation between Helicobacter pylori and autoimmune gastritis was investigated. METHODS Eighty-two consecutive histologically and serologically Helicobacter pylori-positive and 96 Helicobacter pylori-negative patients were enrolled ...

Increasing antimicrobial resistance to key antibiotics in Helicobacter pylori has become a main cause of treatment failures in many countries, including Vietnam. For this reason it is advisable to perform antimicrobial sensitivity tests to provide more focused regimens for H. pylori eradication. However, this approach is generally unavailable for H. pylori in Vietnam and the selection of treatm...

BACKGROUND/AIMS Eradication of Helicobacter pylori is widely accepted as initial therapy for low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, approximately 20% of patients with this disease are not responsive to H. pylori eradication therapy. The aim of this study was to assess remission and relapse rates of low-grade gastric MALT lymphoma after H. pylori eradicatio...

Helicobacter pylori is a gram-negative, helical shaped and microaerophilic bacterium that colonizes in the pathogenesis of chronic gastritis, peptic ulcer disease, and gastric malignancy (Komoto et al., 1998). Since the discovery of Helicobacter pylori in 1983, strong evidence has indicated that H. pylori eradication is current standard treatment and can prevent of chronic gastritis, peptic ulc...

AIM To investigate usefulness of triple therapy with vonoprazan, a potassium ion-competitive acid blocker and antibiotics, for Helicobacter pylori (H. pylori) eradication. METHODS The H. pylori eradication rate was examined in 2507 patients (2055 undergoing primary eradication and 452 undergoing secondary eradication, excluding patients with subtotal gastrectomy) at the Japanese Red Cross Kyo...

Background—Most low grade gastric lymphomas arising from the mucosa associated lymphoid tissue (MALT) are related to Helicobacter pylori colonisation. Cases with disease limited to the stomach can be cured after H pylori eradication and remain in remission for years. In contrast, high grade lymphomas of the stomach, although also related to H pylori, do not usually respond to eradica-

Helicobacter pylori is thought to be important in the pathogenesis of chronic active gastritis, peptic ulceration, gastric adenocarcinoma, and gastric B cell lymphoma of mucosa associated lymphoid tissue. The mechanism of evolution from chronic gastritis to monoclonal B cell proliferation is not known but is thought to be dependent on antigen specific T cells to H pylori and its products. Here,...

Helicobacter pylori causes substantial morbidity and mortality, and the course of infection results from complex interactions between host, environmental and bacterial factors. It is generally accepted that H. pylori eradication is the best method of treatment for peptic ulcer disease and prevention of its complications. However, the antimicrobial agents used in eradication regimens cause vario...
