Helicobacter pylori is a highly successful human bacterium, which is exceptionally equipped to persistently inhabit the human stomach. Colonization by this pathogen is associated with gastric disorders ranging from chronic gastritis and peptic ulcers to cancer. Highly virulent H. pylori strains express the well-established adhesins BabA/B, SabA, AlpA/B, OipA, and HopQ, and a type IV secretion system (T4SS) encoded by the cag pathogenicity island (PAI). The adhesins ascertain intimate bacterial contact to gastric epithelial cells, while the T4SS represents an extracellular pilus-like structure for the translocation of the effector protein CagA...

Wolfram syndrome (WS) is progressive neurodegenerative disease characterized by early-onset optic atrophy and diabetes mellitus, which can be associated with more extensive central nervous system and endocrine complications. The majority of patients harbour pathogenic WFS1 mutations, but recessive mutations in a second gene, CISD2, have been described in a small number of families with Wolfram syndrome type 2 (WFS2). The defining diagnostic criteria for WFS2 also consist of optic atrophy and diabetes mellitus, but unlike WFS1, this phenotypic subgroup has been associated with peptic ulcer disease and an increased bleeding tendency...

OBJECTIVES: Helicobacter pylori is associated with peptic ulcers and gastric cancer and its eradication aims to prevent these conditions. The recommended eradication regimen is triple therapy, consisting of a proton-pump inhibitor in combination with clarithromycin and amoxicillin or metronidazole for 7 days. Yet, other antibiotic regimens are sometimes prescribed. We aimed to assess the use of eradication therapy for H. pylori in the Swedish population during the last decade. MATERIALS AND METHODS: This population-based study used data from the Swedish Prescribed Drug Register...

Helicobacter pylori (H. pylori), discovered in 1982, is a microaerophilic, spiral-shaped gram-negative bacterium that is able to colonize the human stomach. Nearly half of the world's population is infected by this pathogen. Its ability to induce gastritis, peptic ulcers, gastric cancer and mucosa-associated lymphoid tissue lymphoma has been confirmed. The susceptibility of an individual to these clinical outcomes is multifactorial and depends on H. pylori virulence, environmental factors, the genetic susceptibility of the host and the reactivity of the host immune system...

Upper gastrointestinal bleeding (UGIB) represents one of the most serious conditions of the gastrointestinal tract with a mortality rate of 10%. The main cause of UGIB is peptic ulcer, accounting for 28%-59% of cases. A rare cause of UGIB is submucosal arterial collaterals, which develop after splenic artery thrombosis. UGIB secondary to gastric submucosal collateral arteries should be considered in patients with endoscopic appearance of varicose veins in the absence of portal hypertension. Computed tomography angiography (CTA) is the only fast and noninvasive definitive imaging technique for such patients...

Helicobacter pylori lipopolysaccharide promotes chronic gastric colonisation through O-antigen host mimicry and resistance to mucosal antimicrobial peptides mediated primarily by modifications of the lipid A. The structural organisation of the core and O-antigen domains of H. pylori lipopolysaccharide remains unclear, as the O-antigen attachment site has still to be identified experimentally. Here, structural investigations of lipopolysaccharides purified from two wild-type strains and the O-antigen ligase mutant revealed that the H...

BACKGROUND: Proton pump inhibitors (PPIs) are a class of medications that reduce acid secretion and are used for treating many conditions such as gastroesophageal reflux disease (GERD), dyspepsia, reflux esophagitis, peptic ulcer disease, and hypersecretory conditions (e.g. Zollinger-Ellison syndrome), and as part of the eradication therapy for Helicobacter pylori bacteria. However, approximately 25% to 70% of people are prescribed a PPI inappropriately. Chronic PPI use without reassessment contributes to polypharmacy and puts people at risk of experiencing drug interactions and adverse events (e...

1. Proton pump inhibitors have been extensively used for the treatment of ailments due to increased gastric acid secretion such as peptic ulcers, gastroesophageal reflux disease etc. 2. There are several approved drugs in the proton pump inhibitor class with the latest entries representing single enantiomer drugs of the previously approved racemic drugs. 3. Despite having a high degree of structural resemblance, rabeprazole, was shown to possess some unique differentiation from other drugs in the class. One of the key distinguishing features of rabeprazole was related to the lesser involvement of polymorphic metabolism in its pharmacokinetic disposition...
