PURPOSE: The common triple therapy for Helicobacter pylori is challenged by the increasing cases of antibiotic resistant infections, raising the need to explore alternative therapies. Oral administration of egg yolk immunoglobulin Y (IgY) has been previously reported as a means of passive immunization therapy for H. pylori infections. In this work, we investigated the inhibitory effect of IgY on the attachment of H. pylori to AGS cell line. MATERIALS AND METHODS: Recombinant OipA was prepared...

A novel strain of Lactobacillus johnsonii No. 1088 was isolated from the gastric juice of a healthy Japanese male volunteer, and characterized for its effectiveness in the stomach environment. Lactobacillus johnsonii No. 1088 was found to have the strongest acid resistance among several lactobacilli examined (>10% of cells survived at pH 1.0 after 2 h), and such a high acid resistance property was a specific characteristic of this strain of L. johnsonii. When cultured with various virulent bacteria, L. johnsonii No...

BACKGROUND: Eradication of Helicobacter pylori prior to Roux-en-Y gastric bypass (RYGB) has been advocated as a measure to reduce the complications of anastomotic ulceration. However, evidence to support a causal relationship between preoperative H. pylori status and postoperative anastomotic ulceration is weak. METHODS: Intraoperative gastric biopsies were obtained on consecutive patients who underwent laparoscopic RYGB at our institution from December 2007 to June 2010...

NSAID-induced upper gastrointestinal (GI) damage occurs easily in people with a prior history of complicated or uncomplicated ulcers. Many recent clinical studies have proved the benefit of Helicobacter pylori eradication in NSAID users; however, the exact pathophysiologic relationship between concomitant H. pylori infection and NSAID use has not yet been fully elucidated. Testing and eradication of H. pylori are generally recommended in patients who are at a high risk for NSAID-induced GI damage. However, in high-risk patients, ulcer prophylaxis with proton pump inhibitor or misoprostol is needed even if H...

BACKGROUND: Accumulating evidence supports an effect of aspirin in reducing overall cancer incidence and mortality in the general population. We reviewed current data and assessed the benefits and harms of prophylactic use of aspirin in the general population. METHODS: The effect of aspirin for site-specific cancer incidence and mortality, cardiovascular events was collated from the most recent systematic reviews. Studies identified through systematic Medline search provided data regarding harmful effects of aspirin and baseline rates of harms like gastrointestinal bleeding and peptic ulcer...

Anti-platelet drug-induced gastric mucosal injury correlates with intragastric pH. Our aim was to investigate prophylaxis effects of famotidine, one of the representative histamine-2 receptor antagonists (H2RA), on gastric mucosal injury induced by dual therapy with low-dose aspirin and clopidogrel in relation to Helicobacter pylori (H. pylori) infection and CYP2C19 genotypes. This study was conducted for 20 healthy Japanese volunteers (10 H. pylori-positive and 10-negative subjects) with 100 mg aspirin plus 75 mg clopidogrel (AC) once-daily dosing and AC plus 20 mg famotidine twice-daily dosing (ACH)...

BACKGROUND: The modern management of acute non-variceal upper gastrointestinal bleeding is centred on endoscopy, with recourse to interventional radiology and surgery in refractory cases. The appropriate use of intervention to optimize outcomes is reviewed. METHODS: A literature search was undertaken of PubMed and the Cochrane Central Register of Controlled Trials between January 1990 and April 2013 using validated search terms (with restrictions) relevant to upper gastrointestinal bleeding...

A mass screening program using photofluorography has been used as a secondary prophylaxis of gastric cancer in Japan. However, we are at a turning point for reconsidering the strategy of gastric cancer prevention because of various problems with photofluorography. The shift from current secondary prophylaxis to primary prophylaxis is now required. After a Japanese multicenter randomized controlled trial showed that Helicobacter pylori eradication reduced the incidence of metachronous gastric cancer after endoscopic resection of early gastric cancer, primary prophylaxis of gastric cancer has gained greater attention...

Ulceration corresponds to tissue loss, breaching the muscularis mucosae. When ulcers develop in the acid-peptic environment of the gastroduodenum, they are traditionally called peptic ulcer (PUD). Ulcers never develop spontaneously in a healthy gastroduodenal mucosa. Ulceration is the ultimate consequence of a disequilibrium between aggressive injurious factors and defensive mucosa-protective factors. The dominant aggressors are strong acid and high proteolytic (pepsin) activity in gastric secretions. The dominant defensors are the phospholipid surfactant layer, covering the mucus bicarbonate gel, the mucus bicarbonate layer covering the epithelium, the tight junctional structures between the epithelial cells, restricting proton permeability, and the epithelial trefoil peptides, contributing to healing after injury...

Helicobacter pylori (H. pylori) are gram-negative bacteria that selectively colonizes the gastric mucosa. The prevalence of H. pylori infection varies from 20 to 50% in industrialized countries to over 80% in developing countries. The infection may persist lifelong without specific treatment. Prolonged infection and inflammation due to bacterial virulence and host genetic factors will lead to chronic gastritis. A certain portion of infected patients then develop more severe pathologies such as peptic ulcer (10-15%), gastric cancer (1%), and mucosa-associated lymphoid tissue lymphoma (50...

Recommendations in managing patients with nonvariceal upper gastrointestinal bleeding were recently updated, addressing resuscitation, risk assessment and pre-endoscopic care, endoscopy, pharmacotherapy, and secondary prophylaxis. Initial adequate resuscitation and risk stratification using validated scales remain critical. Intravenous erythromycin improves visualization when likely to find blood in the stomach. Pre-endoscopic proton pump inhibition (PPI) does not improve outcomes, but downstages high-risk endoscopic lesions and may be considered...

Low dose aspirin (</=325 mg) is routinely used for primary and secondary prophylaxis of cardiovascular and cerebrovascular events. The use of low dose aspirin is associated with two- to four-fold greater risk of symptomatic or complicated peptic ulcers. Risk factors associated with low dose aspirin induced gastrointestinal toxicity includes prior history of ulcer or upper gastrointestinal (GI) bleeding, concomitant use of other nonsteroidal anti-inflammatory drugs, corticosteroid or warfarin, dual antiplatelet therapy, Helicobacter pylori (H...
