OBJECTIVES: Proton pump inhibitor can effectively prevent recurrent peptic ulcers among atherosclerotic patients receiving clopidogrel monotherapy. However, the interaction between proton pump inhibitors and clopidogrel has raised concerns over the safety of combined use of the two medicines in clinical practice. The aims of this randomized-controlled, double-blind and double-dummy trial were to investigate the efficacy of histamine-2 receptor antagonist (H2RA) in the prevention of recurrent peptic ulcer in patients undergoing thienopyridine monotherapy...

Helicobacter pylori is the main pathogenic bacterium involved in chronic gastritis and peptic ulcer and a class 1 carcinogen in gastric cancer. Current research focuses on the pathogenicity of H. pylori and the mechanism by which it colonizes the gastric mucosa. An increasing number of in vivo and in vitro studies demonstrate that H. pylori can invade and proliferate in epithelial cells, suggesting that this process might play an important role in disease induction, immune escape and chronic infection. Therefore, to explore the process and mechanism of adhesion and invasion of gastric mucosa epithelial cells by H...

Helicobacter pylori is a Gram-negative bacterium that colonizes the human gastric mucosa and is responsible for causing peptic ulcers and gastric carcinoma. The expression of virulence factors allows the persistence of H. pylori in the stomach, which results in a chronic, sometimes uncontrolled inflammatory response. Type II toxin-antitoxin (TA) systems have emerged as important virulence factors in many pathogenic bacteria. Three type II TA systems have previously been identified in the genome of H. pylori 26695: HP0315-HP0316, HP0892-HP0893, and HP0894-HP0895...

Host innate immunity can affect the clinical outcomes of Helicobacter pylori infection, including gastritis, gastric ulcer, gastric adenocarcinoma, and MALT lymphoma. Nucleotide binding oligomerization domain (NOD)-1 and -2 are two molecules of innate immunity which are involved in the host defense against H. pylori. This study aimed to evaluate the effect of the expression level of NOD1 and NOD2 on the susceptibility to gastric cancer as well as peptic ulcer in individuals with H. pylori infection. The gene expression levels of these molecules were compared in three groups of non-ulcer dyspepsia (NUD) as a control group (n=52); peptic ulcer disease (PUD), (n=53); and gastric cancer (GC), (n=39)...

Patients with coronary artery disease (CAD) are destined to lifelong antiplatelet therapy in form of aspirin (acetylsalicylic acid) alone, or in combination with other P2Y2 inhibitors. Proton pump inhibitors (PPIs) are the preferred agents for the treatment and prophylaxis of gastrointestinal injury associated with nonsteroidal anti-inflammatory drug or acetylsalicylic acid or both,(1) but recent data has raised questions about their association with negative cardiovascular events. We report 2 cases of patients with known CAD presented with chest pain mimicking angina pectoris that successfully resolved on discontinuation of the PPIs...

OBJECTIVE: Helicobacter pylori is a bacterial pathogen associated with chronic gastritis, peptic ulcer disease, gastric adenocarcinoma, and gastric mucosa associated lymphoid tissue lymphoma. Current treatment guidelines support a 7- to 14-day, triple-drug protocol consisting of a proton-pump inhibitor (PPI), clarithromycin, and either amoxicillin or an imidazole. The initial eradication rates for this regimen were 80 to 90%. Nevertheless its effectiveness has declined as the antibiotic resistance to clarithromycin and metronidazole has emerged...

BACKGROUND: Hyperphosphatemia is one of the common complications in patients undergoing hemodialysis. Although calcium carbonate (CaC) is often used to control serum inorganic phosphorus level in dialysis patients, co-administration of gastric acid reducers (ARs) may interfere with the phosphate binding effect of CaC. We performed a retrospective medical chart review to study whether ARs attenuate the hypophosphatemic effect of CaC in patients undergoing hemodialysis. METHODS: One hundred and eight chronic hemodialysis patients receiving either CaC alone or CaC concomitant with one of the ARs (proton pump inhibitors and histamine H2-receptor antagonists) were retrieved from the medical charts in Juntendo University Nerima Hospital...

BACKGROUND: The association between stress and peptic ulcers has been questioned since the discovery of helicobacter pylori. This study examined whether high perceived everyday life stress was associated with an increased risk of either receiving a triple treatment or being diagnosed with a peptic ulcer. METHODS: Cohen's perceived stress scale measured the level of stress in a general health survey in 2010 of 17,525 residents of northern Jutland, Denmark, and was linked with National Danish registers on prescription drugs and hospital diagnoses...

PURPOSE: A duodenal bypass after a Roux-en-Y gastric bypass operation for obesity can ameliorate the development of diabetes mellitus (DM). We attempted to determine the subsequent risk of developing DM after subtotal gastrectomy with Billroth II anastomosis (SGBIIA) for peptic ulcer disease (PUD). METHODS: We identified 662 patients undergoing SGBIIA for PUD between 2000 and 2011 from the Longitudinal Health Insurance Database as the study cohort, and we randomly selected 2647 controls from the peptic ulcer population not undergoing SGBIIA and were frequency-matched by age, sex, and index year for the control cohort...

The main innovations of the latest meeting of the Gastroenterological Association (2016) concerning upper gastrointestinal bleeding from the clinician's perspective can be summarised as follows: a) The Glasgow-Blatchford scale has the best accuracy in predicting the need for surgical intervention and hospital mortality; b) Prognostic scales for non-variceal upper gastrointestinal bleeding are also useful for lower gastrointestinal bleeding; c) Preliminary data suggest that treatment with hemospray does not seem to be superior to current standard treatment in controlling active peptic ulcer bleeding; d) Either famotidine or a proton pump inhibitor may be effective in preventing haemorrhagic recurrence in patients taking aspirin, but this finding needs to be confirmed in further studies; e) There was confirmation of the need to re-introduce antiplatelet therapy as early as possible in patients with antiplatelet-associated gastrointestinal bleeding in order to prevent cardiovascular mortality; f) Routine clinical practice suggests that gastrointestinal or cardiovascular complications with celecoxib or traditional NSAIDs are very low; g) Dabigatran is associated with an increased incidence of gastrointestinal bleeding compared with apixaban or warfarin...

This article describes the main conclusions drawn from the presentations on Helicobacter pylori infection in Digestive Diseases Week, 2016. Despite the undeniable widespread reduction in the prevalence of this infection, infection rates continue to be high in developing countries. The prevalence of clarithromycin, metronidazole and quinolone resistance is markedly high in most countries and continues to rise. The management of H. pylori infection in patients with peptic ulcers still leaves much to be desired...

We present a case of intramural duodenal haematoma caused by inferior vena caval (IVC) filter strut perforation requiring innovative open and endovascular retrieval. A 32-year-old woman presents in shock with dull epigastric pain and non-bilious vomiting. She had previously had an IVC filter for deep venous thrombosis and pulmonary embolism. Computed tomography demonstrated strut perforation into the second part of the duodenum, causing intramural haematoma and duodenal obstruction. Laparotomy facilitated evacuation of the duodenal haematoma, while the IVC filter was retrieved by endovascular means...

Helicobacter pylori is a Gram-negative bacterium that inhabits the upper gastrointestinal tract in humans, and the presence of this pathogen in the gut microbiome increases the risk of peptic ulcers and stomach cancer. H. pylori depends on unsaturated fatty acid (UFA) biosynthesis for maintaining membrane structure and function. Although some of the H. pylori enzymes involved in UFA biosynthesis are functionally homologous with the enzymes found in Escherichia coli, we show here that an enzyme HP0773, now annotated as FabX, uses an unprecedented backtracking mechanism to not only dehydrogenate decanoyl-acyl carrier protein (ACP) in a reaction that parallels that of acyl-CoA dehydrogenase, the first enzyme of the fatty acid β-oxidation cycle, but also isomerizes trans-2-decenoyl-ACP to cis-3-decenoyl-ACP, the key UFA synthetic intermediate...

OBJECTIVE: Proton pump inhibitor-based triple therapy with two antibiotics for Helicobacter pylori eradication is widely accepted, but this combination fails in a considerable number of cases. Some studies have shown that cranberry inhibits the adhesion of a wide range of microbial pathogens, including H. pylori. The aim of this study was to assess the effect of cranberry on H. pylori eradication with a standard therapy including lansoprazole, clarithromycin, and amoxicillin (LCA) in patients with peptic ulcer disease (PUD)...
