AIM AND BACKGROUND: Proton pump inhibitors (PPIs) are the main drugs for the treatment of reflux esophagitis. Phase II clinical trials showed that, compared with Esomeprazole, the new PPI Ilaparazole is great in terms of efficacy for reflux symptoms relief and curling for esophagitis. The aim of this study was to confirm suitable dose of Ilaparazole in the treatment of reflux esophagitis. METHODS: This study used a randomized, double-blind, parallel positive drug control, multi-center design...

Governments have several options to reduce the increasing costs of health care, including restrictions for the reimbursement of medicines. Next to the intended effect of reduced costs for medicines, reimbursement restriction can have unintended effects such as patients refraining from their treatment which may lead to health problems and increased use of health care. An example of a reimbursement restriction is the one for proton pump inhibitors (PPIs) that became effective in the Netherlands in January 2012...

Background: Proton pump inhibitors (PPIs) are frequently prescribed antiulcer agents in hospitals and are shown to be safer than H-2 blockers. We present a case report of PPI-induced delirium, regarding which not much has been written in the literature. Case Report: We present a case of a 93-year-old woman with no known past psychiatric history, who was hospitalized for syncope workup and who developed delirium after a double dose of pantoprazole. Discussion: Very few reports of PPI-induced delirium exist in the literature...

Proton pump inhibitors (PPIs) have been widely used in the treatment of gastroesophageal reflux disease and peptic ulcer disease. Although they have a potent acid suppressive effect and excellent efficacy in acid-related diseases, PPI-induced rhabdomyolysis has been reported. Here, we report the case of a patient with reflux esophagitis who developed rhabdomyolysis after esomeprazole treatment. A 67-year-old man with reflux esophagitis who had started esomeprazole treatment for the preceding 10 months complained of back and limb fatigue and myalgia...

Discovery of novel tool compounds and drug leads against a range of unorthodox protein targets has pushed both experimental screening methodologies as well as the field of structure-based design to the limit in recent years. Increasingly, it has been recognized that some of the most desirable targets for the development of small-molecule effectors are actually protein-protein and protein-nucleic acid interactions. There are numerous nontrivial challenges to pursuing small-molecule lead compounds directed toward PPIs and PNIs: relatively shallow cavities, large surface areas that are natively complexed to macromolecules, complex patterns of interstitial waters, a paucity of "hot spots," large conformational changes upon ligand binding, etc...

BACKGROUND: Proton pump inhibitors are among the most commonly prescribed medications worldwide, with dramatic efficacy for upper GI acid related disorders. In recent years, however, the safety of long-term PPI use has been questioned. One issue based on scant and conflicting literature is the possibility of PPI related hypomagnesemia. Our purpose was to assess for any clinically significant alteration in serum magnesium levels in large groups of patients taking different PPIs in varying doses, with or without diuretics...

BACKGROUND: The study aimed to evaluate the efficacy of on-demand therapy using 20-mg vonoprazan for mild reflux esophagitis (RE). METHODS: On-demand therapy by taking one 20-mg tablet of vonoprazan only when reflux symptoms occurred was performed for 24 weeks using 30 patients with mild RE who were receiving maintenance therapy with proton pomp inhibitors (PPIs). The presence or absence of RE, degree of overall satisfaction with the treatment, score of symptoms, and fasting gastrin level before breakfast were examined before and after on-demand therapy...

Signal transduction cascades governed by kinases and GTPases are a critical component of the command and control of cellular processes, with the precise outcome partly determined by direct protein-protein interactions (PPIs). Here, we use the human ROCO proteins as a model for investigating PPI signalling events - taking advantage of the unique dual kinase/GTPase activities and scaffolding properties of these multidomain proteins. We report PPI networks that encompasses the human ROCO proteins, developed using two complementary approaches...

Gastroesophageal reflux disease (GERD), a clinical condition characterized by reflux of gastroduodenal contents in the oesophagus, has proved to demonstrate a strong link between oxidative stress and the development of GERD. Proton pump inhibitors (PPIs) have been universally accepted as first-line therapy for management of GERD. The potential benefits of electrolysed reduced water (ERW), rich in molecular hydrogen, in improving symptoms and systemic oxidative stress associated with GERD was assessed. The study was performed on 84 GERD patients undergoing control treatment (PPI + tap water) or experimental treatment (PPI + ERW) for 3 months...

Mast cells are important effector cells of the immune system, and mast cell-derived exosomes carrying RNAs play a role in immune regulation. However, the molecular function of mast cell-derived exosomes is currently unknown, and here, we identify differentially expressed genes (DEGs) in mast cells and exosomes. We isolated mast cells derived exosomes through differential centrifugation and screened the DEGs from mast cell-derived exosomes, using the GSE25330 array dataset downloaded from the Gene Expression Omnibus database...

Background: Observational studies have linked proton pump inhibitors (PPIs) with serious adverse effects. The study aimed to evaluate internists' perceptions of PPI harms and effects on prescribing. Methods: This was an online survey of a representative sample of the American College of Physicians in 2013. We queried familiarity with and concern about PPI adverse effects (1 - 7 Likert-type scales, anchored by "not at all" and "extremely"). We also asked how frequently (often, sometimes, rarely, or never) participants used any of three "de-escalation" strategies to stop or reduce PPIs because of concern about adverse effects: reducing patients' PPI dose, switching to H2 blocker, or discontinuing PPI...

OBJECTIVES: Proton pump inhibitor (PPI)-responsive eosinophilic esophagitis (EoE) is frequently observed in children, but data on long-term treatment are scarce. The objective of this study is to evaluate the long-term efficacy and safety of PPIs in children with EoE. METHODS: This prospective study enrolled children with EoE and histological remission to an 8-week esomeprazole trial (1 mg/kg/dose, twice daily). Esomeprazole was maintained at 1 mg/kg/day for 1 year...

BACKGROUND: Proton pump inhibitors (PPIs) are usually prescribed to protect against gastrointestinal bleeding in patients on dual antiplatelet therapy. This meta-analysis reviewed clinical outcomes in patients taking aspirin and clopidogrel, with and without concomitant PPIs to address concerns of adverse reactions. METHODS: We searched PubMed, Embase, and the Cochrane Library for articles published between January 1, 2010 and April 11, 2017. The primary end points were major adverse cardiovascular events and gastrointestinal bleeding...

PURPOSE: The purpose of the study is to determine if the use of a proton pump inhibitor (PPI) is associated with an increased fracture risk, as some prior studies have suggested. METHODS: This retrospective cohort study included data on 4438 participants aged 65 and older who had no fracture in the year prior to baseline and had ≥5 years of enrollment history in Kaiser Permanente Washington, an integrated healthcare delivery system in Seattle, WA, during 1994 to 2014...

Nonsteroidal anti-inflammatory drugs (NSAIDs) are often coadministered with proton-pump inhibitors (PPIs) to reduce NSAID-induced gastrointestinal (GI) adverse events. This coadministration is generally regarded as safe, and is included in many of the guidelines on NSAID prescription. However, recent evidence indicates that the GI risks associated with NSAIDs can be potentiated when they are combined with PPIs. This review discusses the GI effects and complications of NSAIDs and how PPIs may potentiate these effects, options for prevention of GI side effects, and appropriate use of PPIs in combination with NSAIDs...

OBJECTIVE: The cost-effectiveness of the recently-introduced generic celecoxib in knee OA has not been examined. METHOD: We used the Osteoarthritis Policy (OAPol) Model, a validated computer simulation of knee OA, to evaluate long-term clinical outcomes, costs, and cost-effectiveness of generic celecoxib in persons with knee OA. We examined eight treatment strategies consisting of generic celecoxib, over-the-counter (OTC) naproxen, or prescription naproxen, with or without prescription or OTC proton-pump-inhibitors (PPIs) to reduce gastrointestinal (GI) toxicity...

BACKGROUND: The association of long-term use of proton pump inhibitors (PPIs) with oesophageal adenocarcinoma has been poorly defined. Our aim was to assess the risk of oesophageal cancer assessing confounding by indication. METHODS: This population-based cohort study included all 796,492 adults exposed to maintenance therapy with PPIs in Sweden in 2005-2012. Standardised incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated to assess the risk of oesophageal adenocarcinoma (and squamous cell carcinoma as a comparison) among long-term PPI users relative to the corresponding background population...

BACKGROUND: Gastroprotectant drugs are used for the prevention and treatment of peptic ulcer disease and might reduce its associated complications, but reliable estimates of the effects of gastroprotectants in different clinical settings are scarce. We aimed to examine the effects of proton-pump inhibitors (PPIs), prostaglandin analogues, and histamine-2 receptor antagonists (H2RAs) in different clinical circumstances by doing meta-analyses of tabular data from all relevant unconfounded randomised trials of gastroprotectant drugs...
