PPI

A new study suggests that co-prescription of low-dose aspirin and PPIs increases the incidence of small-bowel mucosal breaks. Should we be concerned about the potential negative interactions of these drugs? Or is the balance of evidence still substantially tipped towards the need for PPIs to protect against aspirin-induced upper gastrointestinal damage?

BACKGROUNDS/AIMS: Drugs can cause several complications in the esophagus and lead to pill esophagitis. In this paper, our purpose is to share our clinical experience in light of the literature and put forward the general characteristics of pill esophagitis. MATERIALS AND METHODS: In our clinic, between January 2008 and June 2012, by excluding other factors, 48 patients were included in the study, diagnosed as drug-induced esophagitis with their history, endoscopic view, and histopathologic evaluation...

BACKGROUND: Few epidemiologic studies have investigated predictors of uncomplicated peptic ulcer disease (PUD) separately from predictors of complicated PUD. OBJECTIVE: To analyze risk factors associated with uncomplicated PUD and medication use after diagnosis. METHODS: Patients diagnosed with uncomplicated PUD (n = 3,914) were identified from The Health Improvement Network database among individuals aged 40-84 years during 1997-2005, with no previous history of PUD...

BACKGROUND: Asthma, laryngitis and chronic cough are atypical symptoms of the gastroesophageal reflux disease. AIM: To analyze the efficacy of laparoscopic surgery in the remission of extra-esophageal symptoms in patients with gastroesophageal reflux, related to asthma. METHODS: Were reviewed the medical records of 400 patients with gastroesophageal reflux disease submitted to laparoscopic Nissen fundoplication from 1994 to 2006, and identified 30 patients with extra-esophageal symptoms related to asthma...

BACKGROUND: Several epidemiologic studies have suggested the association between therapy with proton pump inhibitors (PPIs) and bone fractures. AIM: This study aimed at evaluating the effect of omeprazole on bone in normal and ovariectomized Wistar rats and the possible mechanisms involved. MATERIALS AND METHODS: 56 rats were divided into 3 main groups. Normal group; further subdivided into normal control group and two groups which were treated with omeprazole in two doses (20, 40 mg/kg/day i...

BACKGROUND: Patients with ER-negative breast tumors are among the most difficult to treat and exhibit low survival rates due, in part, to metastasis from the breast to various distal sites. Aryl hydrocarbon receptor (AHR) ligands show promise as antimetastatic drugs for estrogen receptor (ER)-negative breast cancer. METHODS: Triple negative MDA-MB-231 breast cancer cells were treated with eight AHR-active pharmaceuticals including 4-hydroxtamoxifen, flutamide leflunomide, mexiletine, nimodipine, omeprazole, sulindac and tranilast, and the effects of these compounds on cell proliferation (MTT assay) and cell migration (Boyden chamber assay) were examined...

AIMS: The potential negative metabolic interaction between proton pump inhibitors and clopidogrel is an unsolved issue. We hypothesized that doubling the clopidogrel maintenance dose (150 mg) would be less effective than switching to prasugrel 10 mg maintenance dose (MD) to overcome this negative interaction. METHOD AND RESULTS: In a randomized study with a factorial design, 82 stable coronary artery disease patients treated with 75 mg clopidogrel MD and aspirin were assigned to receive in a double blind fashion lansoprazole (30 mg/day) or placebo and to receive in an open fashion 150 mg clopidogrel MD or 10 mg prasugrel MD...

BACKGROUND: Gastrointestinal complications are an important problem of antithrombotic therapy. Proton-pump inhibitors (PPIs) are believed to decrease the risk of such complications, though no randomized trial has proved this in patients receiving dual antiplatelet therapy. Recently, concerns have been raised about the potential for PPIs to blunt the efficacy of clopidogrel. METHODS: We randomly assigned patients with an indication for dual antiplatelet therapy to receive clopidogrel in combination with either omeprazole or placebo, in addition to aspirin...

Gastric ulcer is a chronic disease featured with unexpected complications, including bleeding, stenosis and perforation, as well as a high incidence of recurrence. Clinical treatments for gastric ulcer have allowed the rapid development of potent anti-ulcer drugs during the last several decades. Gastric ulcer healing is successful with conventional treatments including H2-receptor antagonists, and proton pump inhibitors (PPIs) have been essential for ulcer healing and prevention of complications. Additionally, Helicobacter pylori eradication therapy is effective in reducing ulcer recurrence and leads to physiological changes in the gastric mucosa which affect the ulcer healing process...

BACKGROUND: Proton pump inhibitors (PPIs) may reduce the risk of esophageal adenocarcinoma (EAC) in patients with Barrett's esophagus. PPIs are prescribed for virtually all patients with Barrett's esophagus, irrespective of the presence of reflux symptoms, and represent a de facto chemopreventive agent in this population. However, long-term PPI use has been associated with several adverse effects, and the cost-effectiveness of chemoprevention with PPIs has not been evaluated. AIM: The purpose of this study was to assess the cost-effectiveness of PPIs for the prevention of EAC in Barrett's esophagus without reflux...

OBJECTIVES: To investigate the relationship between use of proton pump inhibitors (PPIs) and incident dependency in older adults discharged from acute care hospitals. DESIGN: Prospective observational study. SETTING: Eleven geriatric and internal medicine acute care wards located throughout Italy. PARTICIPANTS: Individuals (mean age 79.2 ± 5.5) who were not completely dependent at the time of discharge from participating wards (N = 401)...

Proton pump inhibitors (PPIs) are widely used in the elderly. Recent studies have suggested that long-term PPI therapy is associated with fractures in the elderly, however the mechanism remains unknown. We investigated the association between long-term PPI therapy ≥1 year and fracture risk factors including bone structure, falls, and balance-related function in a post hoc analysis of a longitudinal population-based prospective cohort of elderly postmenopausal women and replicated the findings in a second prospective study of falling in elderly postmenopausal women...

AIM: Chronic cough is the most common extra-esophageal manifestation of gastroesophageal reflux disease (GERD). This study aimed to retrospectively analyze outcomes in patients with GERD-related cough following laparoscopic Nissen fundoplication (LNF) and Stretta radiofrequency (RF) respectively. METHODS: Medical charts of 83 patients with GERD-related cough that underwent LNF or Stretta RF between 2007 and 2012 were retrieved. Symptom scores (heartburn, regurgitation and cough) and proton pump inhibitors (PPIs) usages were evaluated...

OBJECTIVE: Accumulating evidence suggests that the use of proton pump inhibitors (PPIs) is associated with spontaneous bacterial peritonitis (SBP) in cirrhotic patients, although the results are inconsistent. We aimed to examine whether PPI use is associated with SBP in Japan, where the administration of PPIs is strictly regulated. METHODS: In this single-center retrospective study, we reviewed 65 patients with liver cirrhosis who were admitted between January 2008 and January 2013 due to ascites...

BACKGROUND/AIMS: Knowledge of the risk factors associated with adverse outcomes after percutaneous endoscopic gastrostomy (PEG) may be helpful for developing PEG recommendations. The purpose of this study was to identify the clinical risk factors associated with adverse clinical outcomes after PEG, especially regarding the use of proton pump inhibitors (PPIs). METHODS: We retrospectively reviewed the data from PEG patients at seven university hospitals between June 2006 and January 2012...

BACKGROUND: To develop appropriate management strategies for patients who take low-dose aspirin, it is important to identify the risk factors for GI injury. However, few studies have described the risk factors for small-bowel injury in these patients. OBJECTIVE: To investigate factors influencing the risk of small-bowel mucosal breaks in individuals taking continuous low-dose aspirin. DESIGN: Capsule endoscopy data were collected prospectively from 5 institutions...

Adding proton pump inhibitors (PPIs) to endoscopic therapy has become the mainstay of treatment for peptic ulcer bleeding, with current consensus guidelines recommending high-dose intravenous (IV) PPI therapy (IV bolus followed by continuous therapy). However, whether or not high-dose PPI therapy is more effective than low-dose PPI therapy is still debated. Furthermore, maintaining pH ≥ 4 appears to prevent mucosal bleeding in patients with acute stress ulcers; thus, stress ulcer prophylaxis with acid-suppressing therapy has been increasingly recommended in intensive care units (ICUs)...

CONTEXT: Prior mechanistic studies reported that omeprazole decreases the platelet inhibitory effects of clopidogrel, yet the clinical significance of these findings is not clear. OBJECTIVE: To assess outcomes of patients taking clopidogrel with or without a proton pump inhibitor (PPI) after hospitalization for acute coronary syndrome (ACS). DESIGN, SETTING, AND PATIENTS: Retrospective cohort study of 8205 patients with ACS taking clopidogrel after discharge from 127 Veterans Affairs hospitals between October 1, 2003, and January 31, 2006...
