In our previous study, the healing effect of proton pump inhibitor plus rebamipide for endoscopic submucosal dissection-related artificial ulcer smaller than 40 mm showed statistical significance. However, such effect of the combination was not yet clear for ulcers with dissected diameter more than 40 mm. The aim of this present study was to resolve this problem under sufficient statistical pow...

PURPOSE OF REVIEW This review attempts to contextualize some of the clinically important publications of the last 2 years as they relate to the broad topic of dyspepsia and peptic ulcer disease, both Helicobacter pylori and nonsteroidal anti-inflammatory drug-related. RECENT FINDINGS This review includes findings which provide insight with regard to the triaging of dyspeptic subjects, informa...

The proton pump inhibitor omeprazole reduced the intracellular replication of Salmonella enterica serovar Typhimurium in RAW264.7 cells without affecting bacterial growth in vitro or the viability of the host cells. The mechanism was bacteriostatic and interfered with replication mediated by the virulence-associated SPI2 type III secretion system. The proton pump inhibitor bafilomycin A(1), in ...

Achieving the optimal clinical response for patients with upper gastrointestinal peptic disease is important. This response depends on the pathology treated as well as on the choice of proton pump inhibitor. Here, we identify factors in specific disease therapy and proton pump inhibitor (PPI) pharmacokinetic and pharmacodynamic characteristics that help us achieve this goal. These include diffe...

THE AUTHORS HIGHLIGHT NEW DEVELOPMENTS IN RESEARCH on Helicobacter pylori. There is now consensus that all patients with newly diagnosed or recurrent duodenal or gastric ulcers who have a positive test result for H. pylori should be treated for the infection. Patients presenting with complications of ulcers, such as bleeding, should also be treated. H. pylori has recently been classified as a d...

Under normal physiological conditions, gastric acid production is controlled by a negative feedback mechanism. Proton pump inhibitors, such as pantoprazole, inhibit gastric acid secretion by irreversibly binding and inactivating luminally active hydrogen potassium ATPase. Recovery of acid production after treatment with a proton pump inhibitor is driven by new pump synthesis, activation of exis...
