[PMID: 38892973 PMCID: PMC11172701 DOI: 10.3390/jcm13113262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Revised: 05/19/2024] [Accepted: 05/22/2024] [Indexed: 06/21/2024] Open
Abstract
Background: Fexuprazan (Fexuclue®; Daewoong Pharmaceutical Co., Ltd., Seoul, Korea) is a novel potassium-competitive acid blocker (P-CAB). This multi-center, randomized, double-blind, active-controlled, parallel-group, therapeutic confirmatory, phase III study was conducted to assess its efficacy and safety compared with esomeprazole (Nexium®; AstraZeneca, Gothenburg, Mölndal, Sweden) in Korean patients with erosive esophagitis (EE). Methods: This study evaluated patients diagnosed with EE at a total of 25 institutions in Korea between 13 December 2018 and 7 August 2019. After voluntarily submitting a written informed consent form, the patients were evaluated using a screening test and then randomized to either of the two treatment arms. The proportion of the patients who achieved the complete recovery of mucosal breaks at 4 and 8 weeks, the proportion of those who achieved the complete recovery of heartburn at 3 and 7 days and 8 weeks, and changes in the GERD-Health-Related Quality of Life Questionnaire (GERD-HRQL) scores at 4 and 8 weeks from baseline served as efficacy outcome measures. The incidence of treatment-emergent adverse events (TEAEs) and adverse drug reactions (ADRs) and the serum gastrin levels served as safety outcome measures. Results: The study population comprised a total of 231 patients (n = 231) with EE, including 152 men (65.80%) and 79 women (34.20%); their mean age was 54.37 ± 12.66 years old. There were no significant differences in the efficacy and safety outcome measures between the two treatment arms (p > 0.05). Conclusions: It can be concluded that the efficacy and safety of Fexuclue® are not inferior to those of esomeprazole in Korean patients with EE.

Gastric development of pancreatic acinar cell metaplasia after Vonoprazan therapy in rats. Surg Endosc 2023; 37:9366-9372. [PMID: 37644156 DOI: 10.1007/s00464-023-10371-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 07/30/2023] [Indexed: 08/31/2023]
Abstract
BACKGROUND Vonoprazan is a new acid-suppressing drug that received FDA approval in 2022. It reversibly inhibits gastric acid secretion by competing with the potassium ions on the luminal surface of the parietal cells (potassium-competitive acid blockers or P-CABs). Vonoprazan has been on the market for a short time and there are many clinical trials to support its clinical application. However, medical experience and comprehensive clinical data is still limited, especially on how and if, gastric histology is altered due to therapy. METHODS A 12-week experiment trial with 30 Wistar rats was to assess the presence of gastrointestinal morphologic abnormalities upon administration of omeprazole and vonoprazan. At six weeks of age, rats were randomly assigned to one of 5 groups: (1) saline as negative control group, (2) oral omeprazole (40 mg/kg), as positive control group, (3) oral omeprazole (40 mg/kg) for 4 weeks, proceeded by 8 weeks off omeprazole, (4) oral vonoprazan (4 mg/kg), as positive control group, and (5) oral vonoprazan (4 mg/kg) for 4 weeks, proceeded by 8 weeks off vonoprazan. RESULTS We identified non-inflammatory alterations characterized by parietal (oxyntic) cell loss and chief (zymogen) cell hyperplasia and replacement by pancreatic acinar cell metaplasia (PACM). No significant abnormalities were identified in any other tissues in the hepatobiliary and gastrointestinal tracts. CONCLUSION PACM has been reported in gastric mucosa, at the esophagogastric junction, at the distal esophagus, and in Barrett esophagus. However, the pathogenesis of this entity is still unclear. Whereas some authors have suggested that PACM is an acquired process others have raised the possibility of PACM being congenital in nature. Our results suggest that the duration of vonoprazan administration at a dose of 4 mg/kg plays an important role in the development of PACM.

Abstract
BACKGROUND The last 40 years have seen a remarkable change in our understanding of reflux disease. SUMMARY These changes encompass disease definition and impact, pathophysiology, diagnostic testing, regulatory oversight of clinical trials, pharmacotherapy, endoscopic, and surgical treatment. We have also seen a number of promising therapies fail. KEY MESSAGES The future holds the promise of further advances. Adaptive artificial intelligence will take over diagnostics in manometry and pH impedance testing and patient-driven outcomes may be changed by interactions with artificial intelligence rather than humans. Changes in chip technology will allow higher resolution chips to be carried on smaller devices making extra-esophageal areas where reflux may play a role more accessible to prolonged observation and testing.

Proton pump inhibitors interfere with the anti-tumor potency of RC48ADC. Toxicol In Vitro 2021; 79:105292.

Abstract
Antibody-drug conjugates (ADCs) are a promising modality for cancers, but the interaction between them and proton pump inhibitors (PPIs), the common adjuvant drugs for cancer treatment, has not been understood. Here, the interactions between PPIs and RC48ADC, a novel HER2-targeting ADC, were quantified in vitro. CCK-8 assay showed that RC48ADC displayed a significant inhibitory effect on the proliferation of SK-BR-3, NCI-N87 and SK-OV-3 cells with the IC50 values of 4.91 ± 1.15 ng/mL, 14.54 ± 0.85 ng/mL and 11.28 ± 0.68 ng/mL respectively. PPIs alone had no significant anti-tumor effect in the dose range of 1.37-1000 ng/mL. When used together, PPIs inhibited the anti-tumor activity of RC48ADC in a dose-dependent manner. And 1000 ng/mL (~Cmax) PPIs significantly recovered RC48ADC-inhibited cell proliferation by (32.85 ± 2.81) % (p < 0.05). However, cimetidine, a non-PPIs gastric acid secretion inhibitor, had no significant inhibitory effect on RC48ADC. Furthermore, omeprazole, rather than cimetidine, significantly reduced the activity of vacuolar H+-ATPase and Cathepsin B compared with the control cells. These results, if confirmed in vivo, indicate that PPIs are antagonists of RC48ADC, even all ADCs, appearing to be due to inhibition of vacuolar H+-ATPase activity. Moreover, cimetidine combined with ADCs instead of PPIs can prevent an adverse drug interaction.

Abstract
Notwithstanding, proton pump inhibitors (PPIs) are one of the most excellent options for different anti-secretory therapy in terms of improved symptomatic outcomes, numerous epidemiological and cohort studies provide evidence of an association between long-term proton PPIs use and increased fracture risk among users. The present attempt aimed to summarize the effect of long-term use of PPIs on musculoskeletal systems by considering the recent claims of different research groups to understand the risk of osteopenia and osteoporosis and to determine the risk factors associated with these complications. We extracted data from various systematic reviews and meta-analyses, cross-sectional studies, prospective studies, case-control studies, cohort studies, and in-vivo and in-vitro studies to observe the consequence of long-term PPIs uses over the patient's bone health. Recent findings suggested that long-term use of PPIs plays an introductory and cabalistic role in the development of osteoporosis mostly hip fractures by disturbing numerous biological pathways and thus able to set up a link between over-prescription of PPIs and bone loss. Frequent administration of PPIs is associated with a significantly worse outcome to bone mineral density (BMD) profile and produce a negative impression on bone health. Since, there are limited data to determine the association of PPIs use and change in BMD, recommending further studies to find out this dissertation.

Abstract
The stomach is inhabited by diverse microbial communities, co-existing in a dynamic balance. Long-term use of drugs such as proton pump inhibitors (PPIs), or bacterial infection such as Helicobacter pylori, cause significant microbial alterations. Yet, studies revealing how the commensal bacteria re-organize, due to these perturbations of the gastric environment, are in early phase and rely principally on linear techniques for multivariate analysis. Here we disclose the importance of complementing linear dimensionality reduction techniques with nonlinear ones to unveil hidden patterns that remain unseen by linear embedding. Then, we prove the advantages to complete multivariate pattern analysis with differential network analysis, to reveal mechanisms of bacterial network re-organizations which emerge from perturbations induced by a medical treatment (PPIs) or an infectious state (H. pylori). Finally, we show how to build bacteria-metabolite multilayer networks that can deepen our understanding of the metabolite pathways significantly associated to the perturbed microbial communities.

Abstract
Osteoporosis is a genetic disease characterized by progressive reductions in bone mineral density (BMD) leading to an increased risk of fracture. Over the last decade, genome-wide association studies (GWASs) have identified over 1000 associations for BMD. However, as a phenotype BMD is challenging as bone is a multicellular tissue affected by both local and systemic physiology. Here, we focused on a single component of BMD, osteoblast-mediated bone formation in mice, and identified associations influencing osteoblast activity on mouse Chromosomes (Chrs) 1, 4, and 17. The locus on Chr. 4 was in an intergenic region between Wnt4 and Zbtb40, homologous to a locus for BMD in humans. We tested both Wnt4 and Zbtb40 for a role in osteoblast activity and BMD. Knockdown of Zbtb40, but not Wnt4, in osteoblasts drastically reduced mineralization. Additionally, loss-of-function mouse models for both genes exhibited reduced BMD. Our results highlight that investigating the genetic basis of in vitro osteoblast mineralization can be used to identify genes impacting bone formation and BMD.

Abstract
Proton pump inhibitors (PPIs) are used for the long-term treatment of gastroesophageal disorders and the non-prescription medicines for acid reflux. However, there is growing concerns about PPI misuse, overuse and abuse. This study aimed to develop an animal model to examine the effects of long-term use of PPI in vivo. Twenty one Wistar rats were given omeprazole orally or intravenously for 30 days, and caerulein as a positive control. After euthanization, the serum and stool were collected to perform MS-based quantitative analysis of metabolites. We carried out 16S-based profiling of fecal microbiota, assessed the expression of bile acid metabolism regulators and examined the immunopathological characteristics of bile ducts. After long-term PPI exposure, the fecal microbial profile was altered and showed similarity to those observed in high-fat diet studies. The concentrations of several metabolites were also changed in various specimens. Surprisingly, morphological changes were observed in the bile duct, including ductal epithelial proliferation, micropapillary growth of biliary epithelium, focal bile duct stricture formation and bile duct obstruction. These are characteristics of precancerous lesions of bile duct. FXR and RXRα expressions were significantly reduced, which were similar to that observed in cholangiocarcinoma in TCGA and Oncomine databases. We established a novel animal model to examine the effects of long-term use of omeprazole. The gut microbes and metabolic change are consequences of long-term PPI exposure. And the results showed the environment in vivo tends to a high-fat diet. More importantly, we observed biliary epithelial hyperplasia, which is an indicator of a high-fat diet.

Abstract
GOAL The goal of this study was to reduce the percentage of inappropriately prescribed proton pump inhibitors (PPIs) in patients aged 50 and older from 80% (baseline) to 60% within 12 months in an academic, internal medicine clinic. BACKGROUND The use of PPIs has increased drastically worldwide. Internal medicine clinic patients had inappropriate use of PPIs for an average of 4 to 5 years. STUDY A multidisciplinary quality improvement team used the Plan-Do-Study-Act Model of health care improvement and performed a root cause analysis to identify barriers to inappropriate use of PPIs. The outcome measure was the percentage of patients inappropriately prescribed PPI. Process measures were completion rates of PPI risk assessment and esophagogastroduodenoscopy. Interventions included the creation of customized electronic health record templates and education to providers and patients. Analysis was performed using monthly statistical process control charts. RESULTS The average rate of PPI discontinuation was 51.1% (n=92/180), which corresponds to 30.0% inappropriate PPI usage within 12 months. The mean PPI discontinuation rate in the 1-year prestudy, study and 6 months poststudy period was 2.0%, 32.0%, and 49.7%, respectively. The mean esophagogastroduodenoscopy completion rate was 49.8% from the baseline of <30%. CONCLUSIONS We achieved a statistically significant and sustainable reduction of inappropriate PPI use to 30% from the baseline rates of 80% and surpassed our goal within 12 months. This quality improvement was unique as no pharmacy personnel was utilized in this process. The multifaceted strategies in a safety-net internal medicine clinic resulted in successful deprescribing of PPI and can be replicated in other setting.

Abstract
Proton pump inhibitors (PPIs) have become known for the treatment of gastric-acid related disorders. Similar to any other drugs, PPIs have possible adverse reactions, being associated with bone fractures, infections, kidney disease, mineral deficiency, dementia, and pneumonia. Multiple analyses have stated that PPIs therapy may affect bone regeneration and osseointegration process, causing an increased risk of bone fracture, deterioration of bone metabolism and impaired bone healing. In this review, we emphasized the current literature regarding the influence of proton pump inhibitors in the bone regeneration process. Results from the studies suggest a link between PPIs intake and bone regeneration, but several concerns are raised regarding inadequate recipient bone, surgical trauma, limitations on the titanium surface, comorbidities or interference with other pharmacological agents. Further studies are needed to determine whether the impaired bone regeneration process is due to PPI or coexisting factors.

Abstract
In recent years, proton pump inhibitors (PPIs) have been criticized for their various adverse interactions and side effects, creating a dilemma among practitioners regarding their use. Our goal is to review the proper use and possible side effects that might be caused by or associated with PPI use. Conclusions were drawn based on the evidence supporting or refuting short-term and long-term adverse events associated with PPI use. We also looked for the evidence regarding effects of PPIs on gut microbiota and their overall safety profile. Although there are significant discrepancies in the current literature regarding various adverse effects associated with PPI use, current data suggest that PPI use is not associated with an increased risk of bone fractures, community-acquired pneumonia, cardiovascular events, hypocalcemia, and gastric malignancies. A mild increased risk of vitamin B12 deficiency and chronic kidney disease, and a moderate increase in the risk of rebound hypersecretion, small intestinal bacterial overgrowth, and enteric infections, including Clostridium difficile, has been noted with PPI therapy. PPI's link with dementia and spontaneous bacterial peritonitis is not clear and requires further investigation. When used appropriately, PPIs are safe medications and are associated with minimal side effects. A clear indication and potential short-term and long-term side effects should be considered before starting PPI therapy.

Only full adherence to proton pump inhibitors protects against drug-induced upper gastrointestinal bleeding. Eur J Clin Pharmacol 2018; 74:1503-1511. [PMID: 30043109 DOI: 10.1007/s00228-018-2523-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2018] [Accepted: 07/10/2018] [Indexed: 12/19/2022]
Abstract
PURPOSE The use of gastroprotective agents has allowed significant progress in the prevention of upper gastrointestinal bleeding (UGIB) associated with non-steroidal anti-inflammatory drugs (NSAIDs) and antiplatelet agents. Nevertheless, some concerns remain regarding the gastroprotective dosage and treatment duration. Our aim was to study the effect of gastroprotective agents in UGIB induced by NSAIDs and single- or dual-antiplatelet therapy. METHODS A multicenter case-control study was conducted including 577 cases diagnosed with UGIB and 1343 sex-, age-, and hospital-matched controls. To estimate exposure to NSAIDs and gastroprotective agents, consumption was calculated for the 4 weeks prior to hospital admission in terms of defined daily doses (DDDs). Risk groups for UGIB induced by NSAIDs and single- or dual-antiplatelet therapy were defined as a function of each drug dose, use of gastrointestine-damaging drugs, and risk factors for UGIB. Odds ratios (ORs) with 95% confidence intervals (CIs) were adjusted for single- (model 1) and dual- (model 2) antiplatelet therapy. RESULTS Full adherence (> 0.80DDD) to proton pump inhibitors (PPIs) was the only gastroprotective therapy that significantly reduced the risk of UGIB, considering NSAID risk (OR: 0.53; 95% CI: 0.30-0.95) and dose (OR: 0.48; 95% CI: 0.27-0.87) with ORs adjusted for single-antiplatelet therapy (model 1) and NSAID risk (OR: 0.55; 95% CI: 0.31-0.98) and dose (OR: 0.49; 95% CI: 0.28-0.89) with ORs adjusted for dual-antiplatelet therapy (model 2). CONCLUSIONS These results reinforce the recommendation of adding a PPI at effective doses (full adherence) to prevent UGIB induced by NSAIDs, or single- or dual-antiplatelet therapy.

Abstract
Objective This guideline provides evidence-based recommendations on treating patients who present with dysphonia, which is characterized by altered vocal quality, pitch, loudness, or vocal effort that impairs communication and/or quality of life. Dysphonia affects nearly one-third of the population at some point in its life. This guideline applies to all age groups evaluated in a setting where dysphonia would be identified or managed. It is intended for all clinicians who are likely to diagnose and treat patients with dysphonia. Purpose The primary purpose of this guideline is to improve the quality of care for patients with dysphonia, based on current best evidence. Expert consensus to fill evidence gaps, when used, is explicitly stated and supported with a detailed evidence profile for transparency. Specific objectives of the guideline are to reduce inappropriate variations in care, produce optimal health outcomes, and minimize harm. For this guideline update, the American Academy of Otolaryngology—Head and Neck Surgery Foundation selected a panel representing the fields of advanced practice nursing, bronchoesophagology, consumer advocacy, family medicine, geriatric medicine, internal medicine, laryngology, neurology, otolaryngology–head and neck surgery, pediatrics, professional voice, pulmonology, and speech-language pathology. Action Statements The guideline update group made strong recommendations for the following key action statements (KASs): (1) Clinicians should assess the patient with dysphonia by history and physical examination to identify factors where expedited laryngeal evaluation is indicated. These include, but are not limited to, recent surgical procedures involving the head, neck, or chest; recent endotracheal intubation; presence of concomitant neck mass; respiratory distress or stridor; history of tobacco abuse; and whether the patient is a professional voice user. (2) Clinicians should advocate voice therapy for patients with dysphonia from a cause amenable to voice therapy. The guideline update group made recommendations for the following KASs: (1) Clinicians should identify dysphonia in a patient with altered voice quality, pitch, loudness, or vocal effort that impairs communication or reduces quality of life (QOL). (2) Clinicians should assess the patient with dysphonia by history and physical examination for underlying causes of dysphonia and factors that modify management. (3) Clinicians should perform laryngoscopy, or refer to a clinician who can perform laryngoscopy, when dysphonia fails to resolve or improve within 4 weeks or irrespective of duration if a serious underlying cause is suspected. (4) Clinicians should perform diagnostic laryngoscopy, or refer to a clinician who can perform diagnostic laryngoscopy, before prescribing voice therapy and document/communicate the results to the speech-language pathologist (SLP). (5) Clinicians should advocate for surgery as a therapeutic option for patients with dysphonia with conditions amenable to surgical intervention, such as suspected malignancy, symptomatic benign vocal fold lesions that do not respond to conservative management, or glottic insufficiency. (6) Clinicians should offer, or refer to a clinician who can offer, botulinum toxin injections for the treatment of dysphonia caused by spasmodic dysphonia and other types of laryngeal dystonia. (7) Clinicians should inform patients with dysphonia about control/preventive measures. (8) Clinicians should document resolution, improvement or worsened symptoms of dysphonia, or change in QOL of patients with dysphonia after treatment or observation. The guideline update group made a strong recommendation against 1 action: (1) Clinicians should not routinely prescribe antibiotics to treat dysphonia. The guideline update group made recommendations against other actions: (1) Clinicians should not obtain computed tomography (CT) or magnetic resonance imaging (MRI) for patients with a primary voice complaint prior to visualization of the larynx. (2) Clinicians should not prescribe antireflux medications to treat isolated dysphonia, based on symptoms alone attributed to suspected gastroesophageal reflux disease (GERD) or laryngopharyngeal reflux (LPR), without visualization of the larynx. (3) Clinicians should not routinely prescribe corticosteroids for patients with dysphonia prior to visualization of the larynx. The policy level for the following recommendation about laryngoscopy at any time was an option: (1) Clinicians may perform diagnostic laryngoscopy at any time in a patient with dysphonia. Disclaimer This clinical practice guideline is not intended as an exhaustive source of guidance for managing dysphonia (hoarseness). Rather, it is designed to assist clinicians by providing an evidence-based framework for decision-making strategies. The guideline is not intended to replace clinical judgment or establish a protocol for all individuals with this condition, and it may not provide the only appropriate approach to diagnosing and managing this problem. Differences from Prior Guideline (1) Incorporation of new evidence profiles to include the role of patient preferences, confidence in the evidence, differences of opinion, quality improvement opportunities, and any exclusion to which the action statement does not apply (2) Inclusion of 3 new guidelines, 16 new systematic reviews, and 4 new randomized controlled trials (3) Inclusion of a consumer advocate on the guideline update group (4) Changes to 9 KASs from the original guideline (5) New KAS 3 (escalation of care) and KAS 13 (outcomes) (6) Addition of an algorithm outlining KASs for patients with dysphonia

Abstract
This narrative review summarises the benefits, risks and appropriate use of acid-suppressing drugs (ASDs), proton pump inhibitors and histamine-2 receptor antagonists, advocating a rationale balanced and individualised approach aimed to minimise any serious adverse consequences. It focuses on current controversies on the potential of ASDs to contribute to infections-bacterial, parasitic, fungal, protozoan and viral, particularly in the elderly, comprehensively and critically discusses the growing body of observational literature linking ASD use to a variety of enteric, respiratory, skin and systemic infectious diseases and complications (Clostridium difficile diarrhoea, pneumonia, spontaneous bacterial peritonitis, septicaemia and other). The proposed pathogenic mechanisms of ASD-associated infections (related and unrelated to the inhibition of gastric acid secretion, alterations of the gut microbiome and immunity), and drug-drug interactions are also described. Both probiotics use and correcting vitamin D status may have a significant protective effect decreasing the incidence of ASD-associated infections, especially in the elderly. Despite the limitations of the existing data, the importance of individualised therapy and caution in long-term ASD use considering the balance of benefits and potential harms, factors that may predispose to and actions that may prevent/attenuate adverse effects is evident. A six-step practical algorithm for ASD therapy based on the best available evidence is presented.

PROTON PUMP INHIBITORS INCREASE THE OVERALL RISK OF DEVELOPING BACTERIAL INFECTIONS IN PATIENTS WITH CIRRHOSIS. ARQUIVOS DE GASTROENTEROLOGIA 2018; 55:28-32. [PMID: 29561973 DOI: 10.1590/s0004-2803.201800000-09] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/23/2017] [Accepted: 11/28/2017] [Indexed: 12/15/2022]
Abstract
BACKGROUND Acid suppression has been associated with adverse events; such as, enteric infections. Proton pump inhibitors (PPI) are frequently prescribed in patients with cirrhosis, but is unclear if PPI are associated with the development of bacterial infections in these patients. OBJECTIVE To assess the impact of PPI intake on the development of bacterial, viral and fungal infections in patients with cirrhosis. METHODS An observational, retrospective, historic cohort study. The exposed cohort included patients with cirrhosis with chronic use of PPI. The non-exposed cohort had not been using PPI. The follow-up period was 3 years, searching in the medical records for any events of bacterial infection confirmed by bacteriological culture. RESULTS One hundred and thirteen patients met the selection criteria, 44 (39%) had chronic use of PPI; of them, 28 (63.6%) patients had not a clear clinical indication to justify the prescription of PPI. Twenty four (21.2%) patients developed bacterial infections during the follow-up period. In the univariate analysis, decompensated cirrhosis (Child B/C), presence of ascites, history of variceal bleeding, and chronic consumption of PPI were risk factors related to the development of infections. But, in the adjusted multivariate analysis only the chronic use of PPI was associated with development of infections (RR=3.6; 95% CI=1.1-12.3; P=0.04). CONCLUSION There is an over-prescription of PPI without a justified clinical indication. The long-term consumption of PPI in patients with cirrhosis is associated with the development of bacterial infections; therefore these drugs must be carefully prescribed in this specific population.

Abstract
OBJECTIVES To determine the magnitude of non-guideline-recommended prescribing (NGRP) of proton pump inhibitors (PPIs) in the general population, its associated factors and expense. METHODS We undertook a cross-sectional observational study in three community pharmacies in a Spanish region in 2013 involving a total of 302 patients with a prescription for PPIs. The main variable was the NGRP of PPIs. Secondary variables were: gender, age, antidepressants, osteoporosis, osteoarthritis, prescription cost per month and total number of chronic diseases. The cost associated with NGRP was calculated. To evaluate the associated factors, a multivariate binary logistic regression model was constructed and the adjusted odds ratios (OR) were obtained. RESULTS NGRP was observed in 192 cases (63.6%). The average cost associated with NGRP per prescription was 3.24 euros per month. The factors significantly associated with NGRP (p < .05) were: antidepressants (OR = 2.66, p = .001), osteoporosis (OR = 3.53, p = .001), osteoarthritis (OR = 3.57, p < .001) and number of chronic diseases (OR = 0.73, p = .003). CONCLUSION A novel approach was used to quantify the NGRP of PPIs in a Spanish community, as well as the associated economic costs. Qualitative studies are needed to better understand the causes of NGRP of PPIs. This analysis will aid in designing interventions to minimize this problem. LIMITATIONS Qualitative studies are needed to better understand the attitude of health professionals when prescribing PPIs.

Abstract
Proton pump inhibitors (PPIs) are widely used to treat gastric acid-related disorders. Concerns have been raised about potential fracture risk, especially at the hip, spine and wrist. However, fracture risk at other bone sites has not been as well studied. We investigated the association between PPIs and specific fracture sites using an aggregated knowledge-enhanced database, the Food and Drug Administration Adverse Event Reporting System Data Mining Set (AERS-DM). Proportional reporting ratio (PRR) was used to detect statistically significant associations (signals) between PPIs and fractures. We analyzed both high level terms (HLT) and preferred terms (PT) for fracture sites, defined by MedDRA (Medical Dictionary for Regulatory Activities). Of PPI users reporting fractures, the mean age was 65.3 years and the female to male ratio was 3.4:1. Results revealed signals at multiple HLT and PT fracture sites, consistent for both sexes. These included fracture sites with predominant trabecular bone, not previously reported as being associated with PPIs, such as 'rib fractures', where signals were detected for overall PPIs as well as for each of 5 generic ingredients (insufficient data for dexlansoprazole). Based on data mining from AERS-DM, PPI use appears to be associated with an increased risk for fractures at multiple sites.

Abstract
UNLABELLED We analyzed the association of proton pump inhibitors (PPIs) with mortality after osteoporosis-related hip fracture in Austria. PPIs were associated with reduced 90-day mortality but elevated mortality after half a year when initiated pre-fracture. Inpatients and discharged patients on PPIs showed lowered in-hospital and 90-day mortality, respectively. INTRODUCTION We herein investigated use of proton pump inhibitors (PPIs) and mortality among hip fracture patients in a nationwide study in Austria. METHODS In this retrospective cohort study, data on use of PPIs were obtained from 31,668 Austrian patients ≥50 years with a hip fracture between July 2008 and December 2010. All-cause mortality in patients without anti-osteoporotic drug treatment who had received their first recorded PPI prescription in the study period either before or after fracture was compared with hip fracture patients on neither PPIs nor anti-osteoporotic medication using logistic and Cox regression analysis. RESULTS With PPI use, 90-day mortality was significantly reduced, both at initiation before (OR 0.66; p < 0.0001) and after hip fracture (OR 0.23; p < 0.0001). 90-day mortality was also reduced when PPIs were prescribed not until after discharge from the last recorded hip fracture-related hospital stay (OR 0.49; p < 0.0001) except for patients aged <70 years. In a sub-cohort of patients beginning PPIs during hospital stay, in-hospital mortality (0.2%) was substantially reduced relative to matched control patients (3.5%) (p < 0.0001). Longer-term mortality significantly increased after half a year post-fracture only among those who started PPI prescription before fracture. CONCLUSIONS PPI use during and after hospital stay due to hip fracture is associated with a considerable decrease in mortality. These findings could have implications for hip fracture treatment.

Abstract
The aim was to update the 2009 European League against Rheumatism (EULAR) recommendations for the treatment of systemic sclerosis (SSc), with attention to new therapeutic questions. Update of the previous treatment recommendations was performed according to EULAR standard operating procedures. The task force consisted of 32 SSc clinical experts from Europe and the USA, 2 patients nominated by the pan-European patient association for SSc (Federation of European Scleroderma Associations (FESCA)), a clinical epidemiologist and 2 research fellows. All centres from the EULAR Scleroderma Trials and Research group were invited to submit and select clinical questions concerning SSc treatment using a Delphi approach. Accordingly, 46 clinical questions addressing 26 different interventions were selected for systematic literature review. The new recommendations were based on the available evidence and developed in a consensus meeting with clinical experts and patients. The procedure resulted in 16 recommendations being developed (instead of 14 in 2009) that address treatment of several SSc-related organ complications: Raynaud's phenomenon (RP), digital ulcers (DUs), pulmonary arterial hypertension (PAH), skin and lung disease, scleroderma renal crisis and gastrointestinal involvement. Compared with the 2009 recommendations, the 2016 recommendations include phosphodiesterase type 5 (PDE-5) inhibitors for the treatment of SSc-related RP and DUs, riociguat, new aspects for endothelin receptor antagonists, prostacyclin analogues and PDE-5 inhibitors for SSc-related PAH. New recommendations regarding the use of fluoxetine for SSc-related RP and haematopoietic stem cell transplantation for selected patients with rapidly progressive SSc were also added. In addition, several comments regarding other treatments addressed in clinical questions and suggestions for the SSc research agenda were formulated. These updated data-derived and consensus-derived recommendations will help rheumatologists to manage patients with SSc in an evidence-based way. These recommendations also give directions for future clinical research in SSc.

Scarpignato C, Gatta L, Zullo A, Blandizzi C. Effective and safe proton pump inhibitor therapy in acid-related diseases - A position paper addressing benefits and potential harms of acid suppression. BMC Med 2016; 14:179. [PMID: 27825371 PMCID: PMC5101793 DOI: 10.1186/s12916-016-0718-z] [Citation(s) in RCA: 244] [Impact Index Per Article: 30.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2016] [Accepted: 10/14/2016] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The introduction of proton pump inhibitors (PPIs) into clinical practice has revolutionized the management of acid-related diseases. Studies in primary care and emergency settings suggest that PPIs are frequently prescribed for inappropriate indications or for indications where their use offers little benefit. Inappropriate PPI use is a matter of great concern, especially in the elderly, who are often affected by multiple comorbidities and are taking multiple medications, and are thus at an increased risk of long-term PPI-related adverse outcomes as well as drug-to-drug interactions. Herein, we aim to review the current literature on PPI use and develop a position paper addressing the benefits and potential harms of acid suppression with the purpose of providing evidence-based guidelines on the appropriate use of these medications. METHODS The topics, identified by a Scientific Committee, were assigned to experts selected by three Italian Scientific Societies, who independently performed a systematic search of the relevant literature using Medline/PubMed, Embase, and the Cochrane databases. Search outputs were distilled, paying more attention to systematic reviews and meta-analyses (where available) representing the best evidence. The draft prepared on each topic was circulated amongst all the members of the Scientific Committee. Each expert then provided her/his input to the writing, suggesting changes and the inclusion of new material and/or additional relevant references. The global recommendations were then thoroughly discussed in a specific meeting, refined with regard to both content and wording, and approved to obtain a summary of current evidence. RESULTS Twenty-five years after their introduction into clinical practice, PPIs remain the mainstay of the treatment of acid-related diseases, where their use in gastroesophageal reflux disease, eosinophilic esophagitis, Helicobacter pylori infection, peptic ulcer disease and bleeding as well as, and Zollinger-Ellison syndrome is appropriate. Prevention of gastroduodenal mucosal lesions (and symptoms) in patients taking non-steroidal anti-inflammatory drugs (NSAIDs) or antiplatelet therapies and carrying gastrointestinal risk factors also represents an appropriate indication. On the contrary, steroid use does not need any gastroprotection, unless combined with NSAID therapy. In dyspeptic patients with persisting symptoms, despite successful H. pylori eradication, short-term PPI treatment could be attempted. Finally, addition of PPIs to pancreatic enzyme replacement therapy in patients with refractory steatorrhea may be worthwhile. CONCLUSIONS Overall, PPIs are irreplaceable drugs in the management of acid-related diseases. However, PPI treatment, as any kind of drug therapy, is not without risk of adverse effects. The overall benefits of therapy and improvement in quality of life significantly outweigh potential harms in most patients, but those without clear clinical indication are only exposed to the risks of PPI prescription. Adhering with evidence-based guidelines represents the only rational approach to effective and safe PPI therapy. Please see related Commentary: doi: 10.1186/s12916-016-0724-1 .

Abstract
Systemic sclerosis (scleroderma) is a rheumatologic disease characterised not only by inflammation/autoimmunity, but also by tissue fibrosis and vascular lesions. The therapeutic approach to patients is dictated by the organ involvement and includes treatment of vascular and fibrotic disease features beyond mere immunosuppression. Fibrotic features in particular, are still inadequately treated, whereas many drugs have been tested for vascular complications within recent years. In this review, the currently available treatment options for this rare disease are presented. Therapy options in systemic sclerosis have changed over the past 10 years and this trend will also continue in the future.

Randomised trial of the effect of a gastrin/CCK 2 receptor antagonist on esomeprazole-induced hypergastrinaemia: evidence against rebound hyperacidity. Eur J Clin Pharmacol 2016; 73:129-139.

Abstract
PURPOSE Hypergastrinaemia induced by proton pump inhibitor (PPI) therapy may cause ECL-cell and parietal-cell hyperplasia and rebound hyperacidity and dyspepsia after PPI withdrawal. The aim of the study was to assess the effect of different dosage-regimens of netazepide, a gastrin/CCK2 receptor antagonist, on PPI-induced hypergastrinaemia and elevated chromogranin A (CgA). METHODS Six groups of eight healthy subjects participated in a randomised, double-blind study of esomeprazole 40 mg daily for 28 days, in combination with netazepide 1, 5 or 25 mg or placebo, daily, during the last 14 days of esomeprazole or during 14 days after treatment withdrawal. Fasting serum gastrin and plasma CgA were measured during treatment and after withdrawal, as biomarkers of acid suppression and ECL-cell activity, respectively. Dyspepsia was monitored throughout the study. RESULTS Esomeprazole increased gastrin and CgA. Netazepide increased gastrin, but not CgA, and inhibited dose dependently the CgA response to esomeprazole. Gastrin and CgA returned to baseline within 2-3 days of esomeprazole withdrawal; netazepide did not shorten that time. There was no rebound dyspepsia after esomeprazole withdrawal. CONCLUSIONS Esomeprazole and netazepide each increase gastrin, consistent with a secondary effect of gastric acid suppression, but by different mechanisms. Esomeprazole-induced hypergastrinaemia stimulates ECL cells and thereby increases CgA. Netazepide-induced hypergastrinaemia does not increase CgA, because netazepide blocks gastrin/CCK2 receptors on ECL cells. Co-administration of netazepide 5 mg abolishes the effect of esomeprazole-induced hypergastrinaemia on ECL cells. The quick return to baseline of gastrin and CgA and absence of dyspepsia after esomeprazole withdrawal do not support the concept of rebound hyperacidity.

Abstract
OBJECTIVES Previous, large, prescription-event monitoring studies in patients receiving PPI therapy recorded instances of convulsion or seizure. The objective of this study was to quantify the relative risk of seizure associated with the use of proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) in a general population, overall and stratified by epilepsy status, and to determine the effects of demographics and comorbidities. METHODS In this observational study (NCT01744301), patients aged 20-84years in the study period from 1 January 2005 to 31 December 2011 were identified from The Health Improvement Network. In a nested case-control analysis, 8605 patients with seizure were matched to 40000 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using logistic regression. RESULTS After adjustment, there were no associations between current PPI use and seizure risk in the overall population (OR: 1.05; 95% CI: 0.87-1.27), the subcohort with epilepsy (OR: 0.87; 95% CI: 0.49-1.53), and the subcohort without epilepsy (OR: 1.05; 95% CI: 0.87-1.28). There were no associations between current H2RA use and seizure risk in the overall population (OR: 1.16; 95% CI: 0.62-2.18) and the subcohort without epilepsy (OR: 1.02; 95% CI: 0.51-2.01). Seizures were less frequent in women than in men. Dementia/psychosis, anxiety, depression, and use of anxiolytics, antidepressants, and paracetamol were associated with an increased seizure risk. CONCLUSIONS Our study revealed that the use of PPIs and the use of H2RAs were not associated with an increased risk of seizures in the overall population or in the cohorts stratified by epilepsy status.

Abstract
BACKGROUND The prescriptions for proton pump inhibitors (PPI) to treat acid-related disorders continue to rise internationally and in New Zealand. Concerns have been raised regarding its widespread use, costs and potential adverse effects in older people. AIMS This study aimed to characterise the utilisation of PPI by older people (aged 65 years and older) in New Zealand from 2005 to 2013. METHODS Repeated cross-sectional analysis of population-level dispensing data was conducted from 1 January 2005 to 31 December 2013. Dispensing data for all PPI prescriptions from 2005 to 2013 were obtained from the Ministry of Health, New Zealand. Utilisation was measured in defined daily doses (DDD) per 1000 older people per day using the World Health Organization Collaborating Centre for Drug Statistics Methodology anatomic, therapeutic and chemical classification system. Utilisation was standardised by sex, age, ethnicity and district health board. RESULTS Overall PPI utilisation showed a 26.7% increase from 2005 to 2013, from 273.41 to 346.53 DDD/1000/day. The greatest utilisation was observed in individuals aged between 80 and 84 years. Middle Eastern/Latin American/African utilised more PPI compared with other ethnic groups. CONCLUSIONS Utilisation of PPI among older people in New Zealand increased by a fifth from 2005 to 2013. Given the concerns surrounding the long-term PPI use in older people, the appropriateness of the increased utilisation needs to be continuously re-evaluated by prescribers and health policy makers.

Abstract
BACKGROUND Few data are available about obesity surgery in adolescent patients. OBJECTIVE To assess long-term outcomes after laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients <18 years. SETTING University Hospital, Europe. METHODS A retrospective study of prospectively collected data of patients <18 years (childhood group; ChG) (n = 28) treated by LRYGB of which 19 were available for follow-up between 2.4 and 10.2 years (mean 7.2 years). This group of patients was matched with an adult control group (AdG) of randomly chosen patients with similar characteristics who underwent LRYGB during the same period. The extensive survey included a telephonic questionnaire. RESULTS 19 (12 females) of the 28 patients (67.9%) were available for follow-up. Preoperatively, 3 had type 2 diabetes mellitus (T2DM), 1 arterial hypertension, 5 dyslipidemia and 1 sleep apnea. In the ChG, average BMI after 7 years dropped from 38.9 kg/m2 preoperatively to 27.5 kg/m2. In the AdG, average BMI decreased from 39.4 to 27.1 kg/m2 in the same time period (nonsignificant between groups). One patient in the ChG needed a reoperation (internal hernia) versus 3 patients in the AdG (1 leak, 2 obstructions). All patients resolved their initial comorbidities. Two of 12 female patients in the ChG became pregnant 6 and 8 years after surgery, respectively, despite seemingly adequate oral contraception. Compliance with postoperative guidelines was good in 16/19 patients in ChG and in 14/18 patients in the AdG. Overall degree of satisfaction was high: 8.2/10 (SD 1.2, range 6-10) in the ChG and 8.9/10 (SD 1.7, range 5-10) in the AdG. CONCLUSION LRYGB seems to be safe, provide good weight loss, and cure comorbidities in an adolescent population. Satisfaction degree is high. Inadvertent pregnancy despite conventional contraception is a possible issue.

Abstract
ACTIVITY OBJECTIVES: 1. Describe the prescribing cascade of proton pump inhibitors (PPI) in nursing home residents. 2. Identify the statistically significant factors related to the use of PPI and H2 receptor blockers. DISCLOSURE STATEMENT Neither the planners nor the authors have any conflicts of interest to disclose. The current study examined the use of proton pump inhibitor (PPI) drugs in 248 nursing home residents and factors associated with being prescribed a PPI. Ninety-three percent of residents taking a PPI had done so for longer than recommended durations. As anticholinergic burden, vitamin/supplement use, and number of oral products taken daily increased, residents were more likely to be taking a PPI. Higher anticholinergic burden (p = 0.031) and number of oral products taken daily (p = 0.04) were two statistically significant predictors in the final logistic regression model. Significant predictors of PPI use in the current study may be explained by the association between polypharmacy and dyspepsia and the lowering of esophageal sphincter pressure by anticholinergic drugs. High use of PPIs in nursing home residents may represent a prescribing cascade.

Abstract
The need for new acid suppressing agents with improved pharmacology and superior antisecretory effects to address unmet clinical needs in acid-related disorders has been evident for over a decade. Recent new antisecretory drugs (IR-omeprazole and MR-dexlansoprazole) only provide a small incremental advance in control of acid secretion over the delayed-release proton pump inhibitors. Vonoprazan (a new potassium-competitive acid blocker) displays more potent and extended 24 h acid suppression and preliminary Japanese trials translate this into meaningful clinical benefits in gastro-esophageal reflux disease and Helicobacter pylori eradication. We review the vonoprazan information to date and the indications, benefits, and concerns of more effective therapeutic control of acid secretion.

Patient-Provider Interactions Affect Symptoms in Gastroesophageal Reflux Disease: A Pilot Randomized, Double-Blind, Placebo-Controlled Trial. PLoS One 2015; 10:e0136855.

Abstract
Background It is unclear whether the benefits that some patients derive from complementary and integrative medicine (CIM) are related to the therapies recommended or to the consultation process as some CIM provider visits are more involved than conventional medical visits. Many patients with gastrointestinal conditions seek out CIM therapies, and prior work has demonstrated that the quality of the patient-provider interaction can improve health outcomes in irritable bowel syndrome, however, the impact of this interaction on gastroesophageal reflux disease (GERD) is unknown. We aimed to assess the safety and feasibility of conducting a 2x2 factorial design study preliminarily exploring the impact of the patient-provider interaction, and the effect of an over-the-counter homeopathic product, Acidil, on symptoms and health-related quality of life in subjects with GERD. Methods 24 subjects with GERD-related symptoms were randomized in a 2x2 factorial design to receive 1) either a standard visit based on an empathic conventional primary care evaluation or an expanded visit with questions modeled after a CIM consultation and 2) either Acidil or placebo for two weeks. Subjects completed a daily GERD symptom diary and additional measures of symptom severity and health-related quality of life. Results There was no significant difference in GERD symptom severity between the Acidil and placebo groups from baseline to follow-up (p = 0.41), however, subjects who received the expanded visit were significantly more likely to report a 50% or greater improvement in symptom severity compared to subjects who received the standard visit (p = 0.01). Total consultation length, perceived empathy, and baseline beliefs in CIM were not associated with treatment outcomes. Conclusion An expanded patient-provider visit resulted in greater GERD symptom improvement than a standard empathic medical visit. CIM consultations may have enhanced placebo effects, and further studies to assess the active components of this visit-based intervention are warranted.

Abstract
BACKGROUND The routine use of special stains for detection of Helicobacter remains controversial. AIMS To determine the frequency of histologically atypical Helicobacter infection. METHODS All gastric biopsies received at a large pathology reference laboratory over a 6-month period were stained for Helicobacter, and the histologic and clinicopathologic parameters evaluated. RESULTS Amongst 7663 Helicobacter-positive biopsies, 823 (10.7%) did not show typical chronic active gastritis with numerous Helicobacter organisms, and were therefore considered histologically atypical. Rare Helicobacter pylori organisms accounted for 58.0% of all atypical infections; the next most common atypical Helicobacter infection was that with minimal or no gastric inflammation (23.3% of atypical infections). Patients in these groups did not differ demographically from those with other forms of atypical or typical Helicobacter infection, although a small subgroup (6%) was more likely to have had a previously treated infection. CONCLUSIONS In many of these atypical infections, Helicobacter would not have been suspected based on the histologic findings alone, and would have been missed without routine special stains. Performing a sensitive stain could prevent additional testing and allow prompt treatment of the affected patients, thus substantially reducing the risk for peptic ulcer and gastric cancer and preventing the transmission of the infection to family members.

Abstract
OBJECTIVE It has been established that use of proton pump inhibitors (PPIs) is associated with an increased risk of acquiring Clostridium difficile-associated diarrhoea (CDAD). However, it is not known whether the use of PPIs or histamine-2 receptor antagonists (H2RAs) concurrently with CDAD-targeted antibiotic treatment affects clinical response or recurrence rates. DESIGN In two phase 3 trials, patients with toxin-positive CDAD were randomised to receive fidaxomicin 200 mg twice daily or vancomycin 125 mg four times daily for 10 days. Only inpatients with CDAD (due to complete medication record availability) were included in this post hoc analysis: 701 patients, of whom 446 (64%) used PPIs or H2RAs during study drug treatment or follow-up. Baseline factors that were statistically significant in univariate analyses were analysed in multivariate analyses of effects on clinical response and recurrence. RESULTS Multivariate analysis showed that leukocytosis, elevated creatinine and hypoalbuminemia, but not PPI or H2RA use, were significant factors associated with poor clinical responses. Treatment group was the single significant predictor of recurrence; the probability of recurrence after fidaxomicin therapy was half that following vancomycin therapy. CONCLUSIONS Acid-suppressing drugs, used by nearly two-thirds of inpatients with CDAD, did not worsen clinical response or recurrence when used concurrently with fidaxomicin or vancomycin. Therefore, development of CDAD does not require discontinuation of anti-acid treatment in patients who have an indication for continuing PPI or H2RA therapy, such as gastro-oesophageal reflux disease and risk of gastrointestinal bleed.

Abstract
AIMS The aim of the study was to utilize a large national histopathology database for the analysis of the clinical epidemiology of gastric polyps. METHODS In a case-control study, 71,575 case subjects with gastric polyps were compared to 741,351 control subjects without gastric polyps. RESULTS Of all patients, 7.72% harboured fundic gland polyps, 1.79% gastric hyperplastic polyps, 0.09% gastric adenomas, and 0.06% type I neuroendocrine tumours. All types showed a clear-cut age-dependent rise. Reflux disease was significantly more common in patients with fundic gland polyps and significantly less common in patients with gastric adenomas or neuroendocrine tumours. Anaemia was more common in patients with gastric hyperplastic polyps, gastric adenomas, or neuroendocrine tumours. Helicobacter pylori was found significantly less frequently in all subjects with gastric polyps than in controls. Intestinal metaplasia and gastric atrophy were both more common in gastric adenoma and neuroendocrine tumours and less common in fundic gland polyps than in controls. Different polyp types tended to coincide in the same patients. CONCLUSIONS Gastric hyperplastic polyps appeared to mark the beginning of a progression from chronic gastritis to intestinal metaplasia and gastric atrophy, which leads to diminished gastric acid output and increased gastrin secretion. Gastric adenoma and neuroendocrine tumours reflect later stages of this process.

Abstract
CONTEXT Proton pump inhibitor (PPI) increases the risk of decrease in bone mineral density (BMD). However, whether calcitrol improves this situation is unknown. OBJECTIVE The current study investigates the effects of calcitriol on BMD in patients with esomeprazole therapy. MATERIALS AND METHODS Three hundred and eighty-six participants with gastrointestinal ulcerations were enrolled and randomly assigned into controlled and supplemented groups. Participants in the controlled group were prescribed esomeprazole (20 mg/qd), while the supplemented group was prescribed esomeprazole (20 mg/qd) and calcitriol (2.5 μg/qd). BMD, serum levels of calcium, carboxy-terminal collagen crosslinks (CTX), and alkaline-phosphatase (ALP) were assessed. RESULTS (1) No significant between-group difference of age, gender, smoking, previous glucocorticoid use and hemoglobin level was found; (2) after 10.6 ± 0.8 d of PPI therapy, BMD T score in the controlled group was slightly increased compared with initial (-1.25 ± 0.08 versus -1.28 ± 0.06, p = 0.084), while there was no change in the supplemented group (-1.25 ± 0.05 versus -1.26 ± 0.03, p = 0.308); (3) during study termination, calcium level in the supplemented group was slightly higher than the controlled group (2.05 ± 0.03 mmol/L versus 2.01 ± 0.05 mmol/L, p = 0.073), while no significant differences of CTX (366.57 ± 43.71 pg/mL versus 373.15 ± 50.23 pg/mL, p = 0.036) and ALP were found among these two groups (50.47 ± 9.32 U/L versus 52.23 ± 10.45 U/L, p = 0.075). CONCLUSION Patients with gastrointestinal ulcerations with esomeprazole therapy, calcitriol supplement showed no efficacy on BMD changes.

Abstract
Background Neoadjuvant treatment plays a crucial role in the therapy of advanced esophageal cancer. However, response to radiochemotherapy varies widely. Proton pump inhibitors (PPIs) have been demonstrated to impact on chemotherapy in a variety of other cancers. We analyzed the impact of PPI treatment on esophageal cancer cell lines, and investigated mechanisms that mediate the effect of PPI treatment in this tumour. Methods We investigated the effect of esomeprazole treatment on cancer cell survival, adhesion, migration and chemotherapy in human adeno-(OE19) and squamous-cell-carcinoma (KYSE410) cell lines. Furthermore, we investigated the effect of PPI treatment on intra-/extracellular pH and on expression of resistance-relevant miRNAs. Results Esomeprazole significantly inhibited tumour cell survival (in a dose-dependent manner), adhesion and migration in both tumour subtypes. Furthermore, esomeprazole augmented the cytotoxic effect of cisplatin and 5-FU in both tumour subtypes. Surprisingly, PPI treatment led to a significant increase of intracellular pH and a decrease of the extracellular pH. Finally, we found esomeprazole affected expression of resistance-relevant miRNAs. Specifically, miR-141 and miR-200b were upregulated, whereas miR-376a was downregulated after PPI treatment in both tumour types. Conclusion Our study demonstrates for the first time that PPIs impact on tumour cell survival, metastatic potential and sensitivity towards chemotherapy in esophageal cancer cell lines. Furthermore, we observed that in this tumour entity, PPIs do not lead to intracellular acidification, but affect the expression of resistance-relevant miRNAs.

Abstract
OBJECTIVE There have been mounting safety concerns over increasing prescription rates for proton pump inhibitors (PPIs). Trends in PPI use have not been studied in emergency departments (EDs). We characterize trends in PPI use in US EDs. METHODS We used data from the National Hospital Ambulatory Care Survey, from 2001 to 2010, focusing on encounters with a reason for visit with a potential indication for a PPI, histamine receptor (H2) blocker, or antacid. Patient, provider, visit, and hospital-level factors associated with increases in PPI use were evaluated. RESULTS Among included visits, ED PPI prescribing more than doubled from 3.0 (95% confidence interval [CI]: 2.4-3.8) to 7.2% (95% CI: 6.3-8.3) from 2001 to 2010. Histamine receptor blocker use decreased from 6.8% (95% CI: 6.0-7.7) to 5.7% (95% CI: 4.9-6.7) and antacids from 7.2% (95% CI: 6.3-8.2) to 5.5% (95% CI: 4.8-6.3). Proton pump inhibitor prescribing was higher in males and whites yet increased across all demographics, including in adults aged 65 years and older. Proton pump inhibitor prescribing increased significantly in all US regions and across all hospital and payer types. Pantoprazole was the agent with the largest increase in use. CONCLUSIONS Over the past decade, there have been considerable increases in PPI prescribing in US EDs. This trend occurred despite rising safety concerns, even in populations at higher risk for adverse events such as older adults. More education may be needed to ensure that ED providers are familiar with indications for PPIs.

Management of gastric polyps: an endoscopy-based approach. Clin Gastroenterol Hepatol 2013; 11:1374-84.

Abstract
The endoscopic finding of a gastric polyp and the histopathologic report that follows may leave clinicians with questions that have not been addressed in formal guidelines: do all polyps need to be excised, or can they just be sampled for biopsy? If so, which ones and how many should be sampled? What follow-up evaluation is needed, if any? This review relies on the existing literature and our collective experience to provide practical answers to these questions. Fundic gland polyps, now the most frequent gastric polyps in Western countries because of widespread use of proton pump inhibitors, and hyperplastic polyps, the second most common polyps notable for their association with gastritis and their low but important potential for harboring dysplastic or neoplastic foci, are discussed in greater detail. Adenomas have had their name changed to raised intraepithelial neoplasia and are decreasing in parallel with Helicobacter pylori infection; however, they do retain their importance as harbingers of gastric cancer, particularly in East Asia. Gastrointestinal stromal tumors have low incidence and no known associations, but their malignant potential is high; early diagnosis and proper management are crucial. Although rare and benign, inflammatory fibroid polyps need to recognized, particularly by pathologists, to avoid misdiagnosis. Gastric neuroendocrine tumors (carcinoids) are important because of their association with either atrophic gastritis or the multiple endocrine neoplasia syndromes; those that do not arise in these backgrounds have high malignant potential and require aggressive management. The review concludes with some practical suggestions on how to approach gastric polyps detected at endoscopy.

Abstract
Gastroesophageal reflux disease (GERD), a common disorder with troublesome symptoms caused by reflux of gastric contents into the esophagus, has adverse impact on quality of life. A variety of medications have been used in GERD treatment, and acid suppression therapy is the mainstay of treatment for GERD. Although proton pump inhibitor is the most potent acid suppressant and provides good efficacy in esophagitis healing and symptom relief, about one-third of patients with GERD still have persistent symptoms with poor response to standard dose PPI. Antacids, alginate, histamine type-2 receptor antagonists, and prokinetic agents are usually used as add-on therapy to PPI in clinical practice. Development of novel therapeutic agents has focused on the underlying mechanisms of GERD, such as transient lower esophageal sphincter relaxation, motility disorder, mucosal protection, and esophageal hypersensitivity. Newer formulations of PPI with faster and longer duration of action and potassium-competitive acid blocker, a newer acid suppressant, have also been investigated in clinical trials. In this review, we summarize the current and developing therapeutic agents for GERD treatment.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) are a class of medications indicated for the treatment of gastric acid-related diseases. Hypomagnesemia is a rare but serious adverse effect of PPIs. OBJECTIVE To address the association between the use of different PPIs and hypomagnesemia by examining the frequency of occurrence of hypo magnesemia among the reported adverse drug reactions from the Food and Drug Administration (FDA) Adverse Event Reporting System database. METHODS We conducted a cross-sectional study of PPI-associated adverse effect cases reported to the FDA between November 1, 1997, and April 1, 2012. Logistic regression was used to examine the association of sex, age, and different PPIs with hypomagnesemia. χ² analysis was conducted to investigate the association of PPI-associated hypomagnesemia with hypocalcemia and hypokalemia. RESULTS Among 66,102 subjects identified as experiencing 1 or more adverse effects while taking a PPI, 1.0% (n = 693) were reported to have hypomagnesemia. The mean (SD) age of PPI users presenting with hypomagnesemia was 64.4 (12.9) years. Results from logistic regression indicated that, compared with esomeprazole, all other PPIs had a higher rate of hypomagnesemia, with pantoprazole having the highest rate (OR 4.3; 95% CI 3.3-5.7; p < 0.001). The risk of female subjects having hypo magnesemia (OR 0.83; 95% CI 0.71-0.97; p = 0.016) was significantly lower than that of males. Elderly subjects (age >65 years) were at increased risk of PPI-associated hypomagnesemia (OR 1.5; 95% CI 1.2-1.7; p < 0.001). χ² analysis showed strong association between hypomagnesemia and both hypocalcemia (p < 0.001) and hypokalemia (p < 0.001). CONCLUSIONS All PPIs were associated with hypomagnesemia, with esomeprazole having the lowest risk and pantoprazole having the highest risk. The risk of PPI-associated hypomagnesemia was higher in males and the elderly population. Hypocalcemia and hypokalemia commonly coexisted with PPI-associated hypomagnesemia.

Abstract
INTRODUCTION The role of pharmacotherapy in the management of patients with Zollinger-Ellison syndrome (ZES) is often equated with the medical management of acid hypersecretion. However, pharmacotherapy is also increasingly involved in the other management areas of these patients. AREAS COVERED This paper reviews the role of pharmacotherapy in all aspects of the management of patients with ZES. Newer aspects are emphasized. This includes the difficulty of diagnosing ZES in patients taking proton pump inhibitors. Also covered is the role of pharmacotherapy in controlling acid hypersecretion and other hormonal hypersecretory states these patients may develop, including hyperparathyroidism in patients with multiple endocrine neoplasia type 1 and ZES; tumor localization; and the treatment of advanced metastatic disease. The last includes chemotherapy, liver-directed therapies, biotherapy (somatostatin/interferon), peptide radio-receptor therapy and molecular-targeted therapies including the use of mTor inhibitors (everolimus) and tyrosine kinase inhibitors (sunitinib). EXPERT OPINION Pharmacotherapy is now involved in all aspects of the management of patients with ZES, with the result that ZES has progressed from being considered an entirely surgical disease initially to the present where medical treatment plays a major role in almost all aspects of the management of these patients.

Abstract
Gastroesophageal reflux disease can present with a wide variety of extraesophageal symptoms. In particular, the type of disease characterized predominately by laryngopharyngeal reflux may be difficult to diagnose because of the absence of regurgitation or heartburn. The available battery of diagnostic tools is often insufficient to confirm a diagnosis of reflux, so the diagnosis is often made by elimination. In many cases, treatment with proton pump inhibitors will relieve symptoms and respiratory complications, despite the persistence of non-acidic reflux. Such treatment is often employed to "confirm" the diagnosis, as measured by patient response. Many diseases have been related to this condition in the literature. The authors review knowledge about these manifestations and their relationship with refluxed gastric content. Physiopathology, symptoms and treatment are reviewed in order to clarify our understanding of laryngopharyngeal reflux diseases and related manifestations.
