Proton pump inhibitors inhibit the gastric H+/K+-ATPase via covalent binding to cysteine residues of the proton pump. All proton pump inhibitors must undergo acid accumulation in the parietal cell through protonation, followed by activation mediated by a second protonation at the active secretory canaliculus of the parietal cell. The relative ease with which these steps occur with different pro...
Proton pump inhibitor treatment of clindamycin-treated mice elevated the gastric pH and facilitated the establishment of colonization of the large intestine by vancomycin-resistant Enterococcus spp. (75 to 80%, versus 20 to 25% for saline-treated controls) and Klebsiella pneumoniae (90%, versus 30% for saline-treated controls). These findings demonstrate a mechanism by which proton pump inhibit...
Herein, we report on a 24-year-old woman with a large well-marginated gastric mucosa-associated lymphoid tissue (MALT) lymphoma. She presented with dysphagia and epigastric pain. In esophagogastroduodenoscopy there was a huge bulging submucosal mass with normal appearing mucosa in the cardia in addition to a grade B gastro-esophageal reflux disease. She was treated with a proton pump inhibit...
Proton pump inhibitors often are prescribed in combination with clopidogrel to decrease risk of gastrointestinal bleeding after acute coronary syndrome. Clopidogrel is a prodrug that has to be metabolized in the liver to generate the active metabolite. Both medications are metabolized largely by the CYP2C19 enzyme; therefore, concerns exist that a drug-drug interaction during concomitant treatm...
BACKGROUND Helicobacter pylori eradication rates in Portugal are declining, due to increased resistance of this bacterium to antimicrobial agents, especially Clarithromycin. Quadruple Levofloxacin-containing regimens could be an option for first-line treatment, but its efficacy should be evaluated as fluoroquinolone resistance is rapidly increasing. Our aim was to compare the efficacy of Clarit...
conclusions b. oleracea demonstrated similar anti-inflammatory properties to omeprazole in rats with gerd. however, omeprazole also demonstrated genotoxic and cytotoxic effects in rats without gerd. results rats with gerd developed esophagitis and esophageal squamous cell carcinoma. b. oleracea and omeprazole-treated gerd rats presented significantly decreased inflammation in relation to non-tr...
