Joo MK. [ Helicobacter pylori Eradication in Drug-related Peptic Ulcer]. THE KOREAN JOURNAL OF GASTROENTEROLOGY = TAEHAN SOHWAGI HAKHOE CHI 2020; 76:227-231.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) and aspirin are the most frequently prescribed drugs worldwide, and their long-term use often leads to peptic ulcers (PUs) along with serious complications, such as bleeding and perforation. Helicobacter pylori (H. pylori) infection is a significant risk factor for developing NSAID-related PU and ulcer bleeding during long-term aspirin use. In a revised version of the Clinical Guidelines for Drug-induced Peptic Ulcer, two statements regarding H. pylori eradication are recommended. 1) Patients scheduled for long-term NSAID therapy should be tested and treated for H. pylori infection to prevent PU and its complications. 2) Patients with a history of PU receiving long-term low-dose aspirin (LDA) therapy should undergo treatment for H. pylori infection to prevent PU and its complications. On the other hand, unlike NSAID-naïve patients, the preventive effects of H. pylori eradication in chronic NSAID users are unclear. In addition, anti-ulcer drugs, such as proton pump inhibitors, may be necessary for maintenance therapy after H. pylori eradication in a subset of long-term LDA users, particularly if the patients are taking concomitant antiplatelet agents or anticoagulants.

Sarri GL, Grigg SE, Yeomans ND. Helicobacter pylori and low-dose aspirin ulcer risk: A meta-analysis. J Gastroenterol Hepatol 2019; 34:517-525. [PMID: 30408229 DOI: 10.1111/jgh.14539] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 10/25/2018] [Accepted: 10/30/2018] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIM Owing to wide-spread use, low-dose aspirin (LDA) produces a substantial amount of peptic ulcer disease. Current guidelines are ambivalent about the need for Helicobacter pylori eradication to protect against LDA ulcers. This study aimed to determine, through meta-analysis, if (and by how much) infection alters the baseline risk of peptic ulcers during LDA therapy. METHODS Literature screening was performed in MEDLINE and EMBASE from inception to May 2018. Original studies reporting prevalence or incidence of uncomplicated ulcers in LDA users were included. Ulcer endpoints needed to be specified separately, according to H. pylori infection status. Meta-analysis was performed in MIX 2.0 Pro. RESULTS Ten cross-sectional studies and seven randomized controlled trials were included (n = 5964). The pooled odds ratios with 95% confidence intervals (CI) for the risk of LDA ulcers in H. pylori-positive versus H. pylori-negative individuals were 1.68 (95%CI 1.40-2.02) and 1.65 (95%CI 1.29-2.08) under fixed-effects and random-effects models, respectively. Heterogeneity among studies was minimal (I2 = 26.9%). After adjusting for the protective effects of antisecretory drugs, the odds ratios increased to 1.94 (95%CI 1.54-2.46). CONCLUSION This analysis suggests that H. pylori increases the risk of LDA ulcers by almost 70% in a population where some were taking proton pump inhibitors and/or other acid suppressants. Without antisecretory drugs, the risk almost doubles. Clinically, these findings may support the use of a test-and-treat approach to H. pylori in LDA users, particularly those already at higher risk of developing peptic ulcers.

Abstract
Experimental studies showed a dose-dependent gastroprotective effect of statins on non-steroidal anti-inflammatory drug-induced endoscopic lesions, modulated by increasing endogenous nitric oxide and prostaglandin production.We investigated the influence of chronic treatment with statins on the occurrence of endoscopic lesions in patients referred for endoscopic evaluation, adjusted for the most important etiologic and risk factors for peptic ulcer disease and its complications.A consecutive series of 564 patients who underwent upper digestive endoscopy, stratified according to the severity of endoscopic lesions were recruited. Patients with statin therapy were included in the study group (n = 220), while patients without statins in the control group (n = 344). We correlate the influence of chronic statin therapy (at least 6 months) with factors including age up to 50 years, Helicobacter pylori infection, smoking and drinking habits, ulcer history, gastrotoxic drug consumption (low-dose aspirin [ASA], anticoagulants), and comorbidities.H pylori infection was more frequent in patients with mild/severe endoscopic lesions vs. no lesions, in both groups, but the difference was not statistically significant (P >.05). Male gender represented a risk factor (P <.01) for mild/severe endoscopic lesions only in the statin group. The estimated risk for developing mild/severe endoscopic lesions with ASA intake decreased from 6.26 to 3.40 (P <.01) when statin therapy was associated. Patients without statins and ischemic coronary artery disease (P <.01; odds ratio [OR] = 2.99; 95% confidence interval (CI):1.88-4.73), heart failure (P = .01; OR = 2.13; 95% CI:1.36-3.34), systemic atherosclerosis (P = .04; OR = 2.30; 95% CI:1.44-3.67) had a statistically significant increased risk for developing mild/severe endoscopic lesions in comparison with patients in the statin group. In multivariate regression analysis models, smoking (P <.01; OR = 2.69; 95% CI:1.73-4.16), ASA (P <.01; OR = 4.54; 95% CI:2.83-7.16), and coronary artery diseases (P = .01; OR = 1.80; 95% CI:1.15-2.82) were independent risk factors for mild/severe endoscopic lesions, while chronic statin therapy (P <.01; OR = 0.31; 95% CI:0.19-0.51) was associated with a protective effect in all models.The results of the present study support a certain protective role of chronic therapy with statins against endoscopic lesions, especially in ASA consumers or patients with cardiovascular diseases.

Abstract
Background: Current knowledge about clinical and genetic risk factors for aspirin-induced gastric mucosal injury is not sufficient to prevent these gastric mucosal lesions. Methods: We recruited aspirin takers as the exposed group and healthy volunteers as the control group. The exposed group was categorized into two subgroups such as subgroup A as gastric mucosal injury diagnosed by gastroscopy, including erosion, ulcer or bleeding of the esophagus, stomach, or duodenum; subgroup B as no injury of the gastric mucosa was detected by gastroscopy. Clinical information was collected, and 53 single nucleotide polymorphisms were evaluated. Results: Among 385 participants, 234 were in the aspirin-exposed group. According to gastroscopy, 82 belonged to subgroup A, 91 belonged to subgroup B, and gastroscopic results of 61 participants were not available. Using the Chi-square test and logistic regression, we found that peptic ulcer history (odds ratio [OR] = 5.924, 95% confidence intervals [CI]: 2.115–16.592), dual anti-platelet medication (OR = 3.443, 95% CI: 1.154–10.271), current Helicobacter pylori infection (OR = 2.242, 95% CI: 1.032–4.870), male gender (OR = 2.211, 95% CI: 1.027–4.760), GG genotype of rs2243086 (OR = 4.516, 95% CI: 1.180–17.278), and AA genotype of rs1330344 (OR = 2.178, 95% CI: 1.016–4.669) were more frequent in subgroup A than subgroup B. In aspirin users who suffered from upper gastrointestinal bleeding, the frequency of the TT genotype of rs2238631 and TT genotype of rs2243100 was higher than in those without upper gastrointestinal bleeding. Conclusions: Peptic ulcer history, dual anti-platelet medication, H. pylori current infection, and male gender were possible clinical risk factors for aspirin-induced gastric mucosal injury. GG genotype of rs2243086 and AA genotype of rs1330344 were possible genetic risk factors. TT genotype of rs2238631 and TT genotype of rs2243100 may be risk factors for upper gastrointestinal bleeding in aspirin users.

Abstract
Background. Aspirin use for cardiovascular or cancer prevention is limited due to its gastrointestinal side effects. Objective. Our prospective, observational case-control study aims to identify the predictive factors for ulcers in low-dose aspirin consumers (75-325 mg/day). Methods. The study included patients who underwent an upper digestive endoscopy and took low-dose aspirin treatment. Results. We recruited 51 patients with ulcer (ulcer group) and 108 patients with no mucosal lesions (control group). In univariate analysis, factors significantly associated with ulcers were male gender (p = 0.001), anticoagulants (p = 0.029), nonsteroidal anti-inflammatory drugs (p = 0.013), heart failure (p = 0.007), liver (p = 0.011) or cerebrovascular disease (p = 0.004), diabetes mellitus (p = 0.043), ulcer history (p = 0.044), and alcohol consumption (p = 0.018), but not Helicobacter pylori infection (p = 0.2). According to our multivariate regression analysis results, history of peptic ulcer (OR 3.07, 95% CI 1.06-8.86), cotreatment with NSAIDs (OR 8, 95% CI 2.09-30.58) or anticoagulants (OR 4.85, 95% CI 1.33-17.68), male gender (OR 5.2, 95% CI 1.77-15.34), and stroke (OR 7.27, 95% CI 1.40-37.74) remained predictors for ulcer on endoscopy. Conclusions. Concomitant use of NSAIDs or anticoagulants, comorbidities (cerebrovascular disease), and male gender are the most important independent risk factors for ulcer on endoscopy in low-dose aspirin consumers, in a population with a high prevalence of H. pylori infection.

Abstract
BACKGROUND Several clinical guidelines recommend the use of proton pump inhibitors (PPIs) in patients taking low-dose aspirin but report no or limited supporting data. We conducted a systematic review and meta-analysis to examine the effects of co-administration of PPIs in patients taking low-dose aspirin on the risks of adverse gastrointestinal (GI) and cardiovascular (CV) events, and on patient adherence to aspirin. METHODS We searched PUBMED, EMBASE and Cochrane Central Register of Controlled Trials databases for relevant articles published through November 2013. We included randomised controlled trials (RCTs) and observational studies in patients taking low-dose aspirin with and without PPIs. Risk of bias was assessed using the Cochrane Collaboration's tool (for RCTs) and the Newcastle-Ottawa Scale (for observational studies). Pooled risk ratios (RRs) were computed using a random-effects model. RESULTS We included 13 studies, of which 12 (2 RCTs and 10 observational studies) reported on GI events, and one (cohort study) on both GI bleeding and CV events. No study reported on adherence to aspirin. Co-administration of PPIs in patients receiving low-dose aspirin was associated with risk reductions of 73% (RR 0.27, 95% CI 0.17-0.42) and 50% (RR 0.50, 95% CI 0.32-0.80) in the occurrence of peptic ulcer and GI bleeding respectively. There was evidence of bias in publications reporting on the GI events. CONCLUSIONS The practice of co-prescribing PPIs in patients taking low-dose aspirin is supported by some data, but the evidence is rather weak. It currently remains unclear whether the benefits of co-administration of PPIs in users of low-dose aspirin outweigh their potential harms.

Abstract
Antiplatelet drugs are widely used for the prevention of cardiovascular disease and cerebral vascular disorders. Although there have been several studies on gastroduodenal mucosal injury with gastrointestinal (GI) symptoms such as GI bleeding, in antiplatelet drug users (including low-dose aspirin (LDA)), there have been few reports on the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users. This study was a cross-sectional study elucidating the association between antiplatelet drug use and gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Subjects were 186 asymptomatic Japanese antiplatelet drug users who underwent a regular health checkup. Subjects were divided into those with and without gastroduodenal mucosal injury endoscopically, and the association between gastroduodenal mucosal injury and other data in asymptomatic antiplatelet drug users was investigated.The prevalence of males and drinkers were significantly higher in subjects with gastroduodenal mucosal injury than in those without. In addition, the prevalence of proton pump inhibitor (PPI) users was significantly lower in subjects with gastroduodenal mucosal injury than in subjects without gastroduodenal mucosal injury. Logistic regression analysis showed PPI (odds ratios: 0.116; 95% confidence intervals: 0.021-0.638; P < 0.05) was a significant predictor of a decreased prevalence of gastroduodenal mucosal injury and closed-type (C-type) atrophy (3.172; 1.322-7.609; P < 0.01) was a significant predictor of an increased prevalence of severe gastroduodenal mucosal injury in asymptomatic antiplatelet drug users.Gender and lifestyle, such as drinking, may have an impact on risk of gastroduodenal mucosal injury in asymptomatic subjects taking antiplatelet drugs. Although PPI is a significant predictor of a decreased prevalence of gastroduodenal mucosal injury, including in asymptomatic antiplatelet drug users, status of gastric atrophy should also be considered against severe gastroduodenal mucosal injury.

Abstract
Since the Korean College of Helicobacter and Upper Gastrointestinal Research has first developed the guideline for the diagnosis and treatment of Helicobacter pylori infection in 1998, the revised guideline was proposed in 2009 by the same group. Although the revised guideline was made by comprehensive review of previous articles and consensus of authoritative expert opinions, the evidence-based developmental process was not applied in the revision of the guideline. This new guideline has been revised especially in terms of changes in the indication and treatment of H. pylori infection in Korea, and developed by the adaptation process as evidence-based method; 6 guidelines were retrieved by systematic review and the Appraisal of Guidelines for Research and Evaluation (AGREE) II process, 21 statements were made with grading system and revised by modified Delphi method. After revision, 11 statements for the indication of test and treatment, 4 statements for the diagnosis and 4 statements for the treatment have been developed, respectively. The revised guideline has been reviewed by external experts before the official endorsement, and will be disseminated for usual clinical practice in Korea. Also, the scheduled update and revision of the guideline will be made periodically.

Abstract
For most patients with prior cardiovascular events, preventing future secondary cardiovascular events requires life-long persistence with antiplatelet therapy. PA tablets (P: proton pump inhibitors; A: aspirin) are investigational compounds that were developed to provide the cardioprotective benefits of aspirin with the upper gastrointestinal protection of a proton pump inhibitor (e.g., omeprazole). The tablets are film-coated, coordinated-release tablets for oral administration that contain 40 mg immediate-release omeprazole and either 81 or 325 mg delayed-release aspirin. The goals of the clinical development program were to demonstrate the following: improved gastrointestinal safety of PA relative to enteric-coated aspirin alone; bioequivalence and comparative bioavailability between the PA compounds and currently marketed enteric-coated aspirin; and long-term safety. Two clinical pharmacology studies were also conducted to study the potential for interaction between PA32540 and clopidogrel.

Abstract
BACKGROUND & AIMS Guidelines recommend prescribing gastroprotective agents (proton pump inhibitors, misoprostol) to older patients (primarily ≥65 years old) taking nonsteroidal anti-inflammatory drugs (NSAIDs) to prevent gastrointestinal ulcers. Older individuals are underrepresented in clinical trials of these agents. We systematically reviewed evidence from observational studies on the use of gastroprotective agents in elderly patients and their ability to prevent NSAID-related ulcers in this population. METHODS We performed a systematic search of Embase and MEDLINE and identified 23 observational studies that focused on elderly patients and reported data on co-prescription of gastroprotective agents and NSAIDs and/or the effectiveness of the agents in preventing gastrointestinal events in NSAID users. We collected data on rates of co-prescription and NSAID-related gastrointestinal events in patients with and without gastroprotection. RESULTS A median of 24% (range, 10%-69%) of elderly patients taking NSAIDs received a co-prescription for gastroprotective agents; this percentage was only slightly higher in the oldest age groups. All studies of efficacy showed a positive effect of gastroprotection. However, the adjusted results were not suitable for synthesis, and the 5 studies reporting unadjusted results were too heterogeneous for meta-analysis (I(2) = 97%). The studies differed in outcomes, definitions of co-prescription, and differences in baseline risk factors between patients with and without gastroprotection. None of the studies assessed adverse effects of gastroprotective agents. The 2 cost-effectiveness studies reached opposing conclusions. CONCLUSIONS In a systematic review, the observational evidence for the efficacy of gastroprotective agents in preventing NSAID-associated gastrointestinal events was in agreement with results of randomized controlled trials. However, because of heterogeneity of included studies, it is not clear what the effect would be if more patients were treated, or at what age gastroprotection should be recommended. We offer suggestions to facilitate comparison with other work and address the questions of risk and benefit in relation to age.

Abstract
Signicant progress has been obtained since the Second Brazilian Consensus Conference on Helicobacter pylori Infection held in 2004, in São Paulo, SP, Brazil, and justify a third meeting to establish updated guidelines on the current management of H. pylori infection. The Third Brazilian Consensus Conference on H pylori Infection was organized by the Brazilian Nucleus for the Study of Helicobacter, a Department of the Brazilian Federation of Gastroenterology and took place on April 12-15, 2011, in Bento Gonçalves, RS, Brazil. Thirty-one delegates coming from the five Brazilian regions and one international guest, including gastroenterologists, pathologists, epidemiologists, and pediatricians undertook the meeting. The participants were allocated in one of the five main topics of the meeting: H pylori, functional dyspepsia and diagnosis; H pylori and gastric cancer; H pylori and other associated disorders; H pylori treatment and retreatment; and, epidemiology of H pylori infection in Brazil. The results of each subgroup were submitted to a final consensus voting to all participants. Relevant data were presented, and the quality of evidence, strength of recommendation, and level of consensus were graded. Seventy per cent and more votes were considered as acceptance for the final statement. This article presents the main recommendations and conclusions to guide Brazilian doctors involved in the management of H pylori infection.

Gastroenterology 2013; 144:528-35. [PMID: 23333655 DOI: 10.1053/j.gastro.2012.12.038] [Citation(s) in RCA: 78] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2012] [Revised: 11/27/2012] [Accepted: 12/04/2012] [Indexed: 12/11/2022]
Abstract
BACKGROUND & AIMS Current guidelines recommend testing for Helicobacter pylori infection among users of low-dose aspirin (ASA) who are at high risk for developing ulcers. However, it is not clear whether this strategy affects long-term risk of ulcer bleeding. We assessed the utility of testing ASA users with a high risk of ulcer bleeding for H pylori infection. METHODS In a prospective study, we recruited 3 cohorts of ASA users (≤160 mg/day). The first group included H pylori-positive users of ASAs with bleeding ulcers in whom the infections were eradicated (n = 249). They resumed ASA after ulcer healing and H pylori eradication. The second group included H pylori-negative (past and present) users of ASA who developed bleeding ulcers (n = 118). They received enteric-coated ASA after ulcer healing. The average-risk cohort included new users of ASA without a history of ulcers (n = 537). None of the subjects received regular treatment with anti-ulcer drugs. The primary end point was ulcer bleeding with ASA use in 5048 patient-years of follow-up evaluation. RESULTS The incidence of ulcer bleeding (per 100 patient-years) in the H pylori-eradicated cohort (0.97; 95% confidence interval [CI], 0.53-1.80) did not differ significantly from that of the average-risk cohort (0.66; 95% CI, 0.38-0.99). The H pylori-negative cohort had a high incidence of recurrent bleeding (5.22; 95% CI, 3.04-8.96) (incidence rate ratio, 8.52; 95% CI, 4.29-16.95 vs the average-risk cohort). CONCLUSIONS The long-term incidence of recurrent ulcer bleeding with ASA use is low after H pylori infection is eradicated. ASA users without current or past H pylori infections who develop ulcer bleeding have a high risk of recurrent bleeding. Tests for H pylori infection can be used to assign high-risk ASA users to groups that require different gastroprotective strategies.

Abstract
BACKGROUND Patients using low-dose aspirin (LDA) have an increased risk of gastroduodenal mucosal lesions and upper gastrointestinal symptoms. We aimed to clarify the efficacy of rabeprazole for preventing peptic ulcer, esophagitis, and gastrointestinal symptoms associated with LDA. METHODS Patients with a history of peptic ulcers who were receiving LDA for cardiovascular or cerebrovascular disease were randomly assigned to receive rabeprazole at 10 mg daily, rabeprazole at 20 mg daily, or gefarnate (a cytoprotective anti-ulcer agent) at 50 mg twice daily. The primary endpoint was the development of gastric and/or duodenal ulcer at 12 weeks. The modified Lanza score (MLS) and gastrointestinal symptoms were evaluated at baseline and at 12 weeks. RESULTS The full analysis set comprised 261 patients (rabeprazole 10 mg: n = 87, rabeprazole 20 mg: n = 89, gefarnate 100 mg: n = 85). The cumulative incidences of gastroduodenal ulcers at 12 weeks in the 10 mg rabeprazole group, 20 mg rabeprazole group, and gefarnate group were 7.4, 3.7, and 26.7 %, respectively (rabeprazole group 5.5 % vs. gefarnate group 26.7 %, hazard ratio [HR] 0.179; 95 % confidence interval [CI] 0.082-0.394; p < 0.0001). The proportions of patients with an MLS of ≥1 and erosive esophagitis were significantly lower in the rabeprazole group than in the gefarnate group at 12 weeks (gastric lesions 33.5 vs. 62.4 %, p < 0.0001; duodenal lesions 5.7 vs. 24.7 %, p < 0.0001; erosive esophagitis 5.8 vs. 19.4 %, p < 0.0001). Rabeprazole was significantly more effective than gefarnate for the resolution and prevention of gastrointestinal symptoms (resolution 53.6 vs. 25.0 %, p = 0.017; occurrence 9.2 vs. 28.3 %, p = 0.0026). CONCLUSIONS Rabeprazole is more effective than gefarnate for reducing the risk of recurrence of peptic ulcer, esophagitis, and gastrointestinal symptoms in LDA users.

Abstract
Recent data report that the incidence of peptic ulcer is decreasing in the general population; conversely, the rates of gastric and duodenal ulcer hospitalization and mortality remain very high in older patients. Two major factors that might explain this epidemiological feature in the elderly population are the high prevalence of Helicobacter pylori infection and the increasing prescriptions of gastroduodenal damaging drugs, including NSAIDs and/or aspirin (acetylsalicylic acid). The main goals for treating peptic ulcer disease in old age are to reduce recurrence of the disease and to prevent complications, especially bleeding and perforation. The available treatments for peptic ulcer are essentially based on gastric acid suppression with antisecretory drugs and the eradication of H. pylori infection. The aim of this article is to report the available data on clinical efficacy and tolerability of peptic ulcer treatments in elderly patients and provide recommendations for their optimal use in this special population. Proton pump inhibitor (PPI)-based triple therapies for 7 days are highly effective for the cure of H. pylori-positive peptic ulcers as well as for reducing ulcer recurrence. Antisecretory drugs are also the treatment of choice for NSAID- or aspirin-related peptic ulcers and are useful as preventive therapy in chronic users of NSAIDs and low-dose aspirin as antiplatelet therapy. Antisecretory PPI therapy has a favourable tolerability profile in geriatric patients; however, monitoring is suggested in older patients with frequent pulmonary infections, gastrointestinal malabsorption, unexplained chronic diarrhoea, osteoporosis or those taking concomitant cytochrome P450 2C19-metabolized medications. The overall approach to the geriatric patient should include a comprehensive geriatric assessment that ensures multidimensional evaluation of the patient in order to better define the clinical risk of adverse outcomes in the older patient with peptic ulcer and its complications.

Abstract
Low dose aspirin (≤325 mg) is routinely used for primary and secondary prophylaxis of cardiovascular and cerebrovascular events. The use of low dose aspirin is associated with two- to four-fold greater risk of symptomatic or complicated peptic ulcers. Risk factors associated with low dose aspirin induced gastrointestinal toxicity includes prior history of ulcer or upper gastrointestinal (GI) bleeding, concomitant use of other nonsteroidal anti-inflammatory drugs, corticosteroid or warfarin, dual antiplatelet therapy, Helicobacter pylori (H. pylori) infection, and advanced age. Esomeprazole, like other proton pump inhibitors (PPIs) is very effective in decreasing the risk of aspirin induced gastrointestinal toxicity. Although evidence to support esomeprazole or other PPIs for primary prophylaxis in aspirin induced gastrointestinal toxicity is limited, its role in secondary prophylaxis is well established.

Abstract
BACKGROUND We aimed to elucidate the risk factors and preventive factors associated with chronic low-dose aspirin (L-ASA)-induced gastroduodenal mucosal injury in Japanese patients with arteriosclerotic disease. METHODS This retrospective observational study included 400 L-ASA users who underwent upper gastrointestinal endoscopy. We investigated patients' clinical characteristics, including age, peptic ulcer history, concomitant drugs [i.e. gastric agents, antiplatelet drugs, anticoagulants, non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids], abdominal symptoms, endoscopic findings, and interruption of L-ASA before endoscopy. The severity of gastroduodenal mucosal lesions was evaluated using the modified LANZA score (MLS). RESULTS Of 400 patients, 249 (62%) and 41 (10%) had gastroduodenal mucosal lesions (MLS ≥1) and gastroduodenal ulcers, respectively. Peptic ulcer history, abdominal symptoms, proton pump inhibitor (PPI), histamine type 2-receptor antagonists (H2RA), and the cessation of L-ASA before endoscopy were significantly associated with L-ASA-induced gastroduodenal ulcers; the odds ratio (OR) (confidence interval (CI)) was 5.49 (1.82-16.55), 4.56 (1.93-10.75), 0.12 (0.03-0.42), 0.13 (0.04-0.40) and 0.11 (0.04-0.29), respectively. Moreover, patients having two or more of five factors [i.e. advanced age (≥75), anticoagulants, antiplatelet drugs, NSAIDs and corticosteroids] had a significantly higher prevalence of L-ASA-induced gastroduodenal ulcers [OR (CI): 2.39 (1.002-5.69)]. CONCLUSION Peptic ulcer history, abdominal symptoms and the summation of risk factors increased the risk for L-ASA-induced gastroduodenal ulcers. H2RAs and PPIs were effective for the prevention of L-ASA-induced gastroduodenal ulcers. The cessation of L-ASA before endoscopy might lead to the underestimation of L-ASA-induced gastroduodenal injury.

Abstract
The efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) for the treatment of inflammation and pain of various origins is well established. Prescribing these drugs, however, remains a challenge because a great variety of gastrointestinal and cardiovascular safety issues need to be considered, particularly in older patients. Recent recommendations suggest that the prescription of non-selective NSAIDs and/or selective cyclo-oxygenase-2 inhibitors (coxibs) may be appropriate in patients with low gastrointestinal risk (no prior gastrointestinal events, no concomitant treatments with other damaging drugs). Gastroprotection is appropriate in patients with gastrointestinal risk factors and in older patients. In patients at high risk for gastrointestinal and cardiovascular events, however, NSAID or coxib prescriptions are contraindicated. Multidimensional impairment is a crucial point in evaluating the clinical outcome of older patients; thus, a comprehensive geriatric assessment is useful in predicting adverse outcomes, including morbidity and mortality.

Abstract
The Asia-Pacific Consensus Conference was convened to review and synthesize the most current information on Helicobacter pylori management so as to update the previously published regional guidelines. The group recognized that in addition to long-established indications, such as peptic ulcer disease, early mucosa-associated lymphoid tissue (MALT) type lymphoma and family history of gastric cancer, H. pylori eradication was also indicated for H. pylori infected patients with functional dyspepsia, in those receiving long-term maintenance proton pump inhibitor (PPI) for gastroesophageal reflux disease, and in cases of unexplained iron deficiency anemia or idiopathic thrombocytopenic purpura. In addition, a population 'test and treat' strategy for H. pylori infection in communities with high incidence of gastric cancer was considered to be an effective strategy for gastric cancer prevention. It was recommended that H. pylori infection should be tested for and eradicated prior to long-term aspirin or non-steroidal anti-inflammatory drug therapy in patients at high risk for ulcers and ulcer-related complications. In Asia, the currently recommended first-line therapy for H. pylori infection is PPI-based triple therapy with amoxicillin/metronidazole and clarithromycin for 7 days, while bismuth-based quadruple therapy is an effective alternative. There appears to be an increasing rate of resistance to clarithromycin and metronidazole in parts of Asia, leading to reduced efficacy of PPI-based triple therapy. There are insufficient data to recommend sequential therapy as an alternative first-line therapy in Asia. Salvage therapies that can be used include: (i) standard triple therapy that has not been previously used; (ii) bismuth-based quadruple therapy; (iii) levofloxacin-based triple therapy; and (iv) rifabutin-based triple therapy. Both CYP2C19 genetic polymorphisms and cigarette smoking can influence future H. pylori eradication rates.

Abstract
BACKGROUND There are few studies on the association of the risks of upper gastrointestinal (GI) ulcer induced by aspirin combined with other medicines. We investigated the association between peptic ulcer and clinical parameters, including Helicobacter pylori infection and combinations of medicines. METHODS Patients taking 100 mg aspirin for cardiovascular diseases who were planning to undergo endoscopy were enrolled. Serum H. pylori IgG antibody was measured. RESULTS A total of 305 patients were enrolled, and 38 patients (12.4%) had ulcer lesions. Sex, smoking, drinking, body mass index, endoscopic findings for gastric atrophy (open type), or presence of H. pylori were not significantly associated with ulcer lesions. Cotreatment with anticoagulants [ticlopidine, 34.2% vs. 21.3%; adjusted odds ratio (OR), 3.1; 95% confidence interval (CI), 1.4-7.1; ticlopidine plus warfarin, 13.2% vs. 3.7%; adjusted OR, 4.4; 95% CI, 1.3-15], proton pump inhibitor (PPI 5.3% vs. 34.8%; adjusted OR, 0.10; 95% CI, 0.02-0.43), and antihypertensive medicine were significantly associated with peptic ulcer. Among antihypertensive medicines, AT1 receptor blocker and angiotensin-converting enzyme (ACE) inhibitor tended to be associated with upper GI ulcer. CONCLUSIONS PPI was superior to H2-receptor antagonist for prevention of peptic ulcer, and cotreatment with AT1 receptor blocker or ACE inhibitor seemed to reduce peptic ulcer among patients taking low-dose aspirin.

Abstract
GOAL To review the literature on the significance, risk factors, and management of occult and gross gastrointestinal (GI) bleeding in patients on antiplatelets and/or anticoagulants. STUDY Relevant original and review articles and their bibliographies were analyzed. Estimates of risks and therapeutic outcomes were obtained from randomized trials, whereas risk factor identification was gathered from cross-control and prospective cohort studies. RESULTS Antiplatelets and anticoagulants do not diminish the positive predictive value of fecal occult blood testing to find GI pathology. They increase the risk of gross GI bleeding, and predictors of hemorrhage include history of GI bleeding or ulcer disease, higher intensity of anticoagulation, combination therapy, and presence of comorbid conditions. A bleeding site is identified in most patients with peptic ulcer being the most common. In case of significant bleeding, complete or partial reversal of anticoagulation is undertaken on the basis of the balance of risks between bleeding and thromboembolic events. Early endoscopy can reveal lesions requiring endoscopic hemostasis, which can be performed in the setting of low-intensity anticoagulation. In patients with history of peptic disease or bleeding from an acid-related lesion, proton-pump inhibitors and Helicobacter pylori eradication reduce the risk of upper GI bleeding even when antiplatelet therapy is continued. CONCLUSIONS Predictors of bleeding on antiplatelets and/or antithrombotics therapy have been identified, but formulation and validation of a GI bleeding index for stratification of risk in individual patients is suggested. Reversal of anticoagulation in bleeding patients is associated with a low risk of thromboembolic events and permits the performance of diagnostic and therapeutic endoscopy. Proton-pump inhibitors and H. pylori eradication reduce the risk of rebleeding in those with acid-related disease.

Abstract
BACKGROUND The most effective schedule of proton pump inhibitor (PPI) administration following endoscopic hemostasis of bleeding ulcers remains uncertain. METHODS Patients with actively bleeding ulcers and those with nonbleeding visible vessel or adherent clot were treated with epinephrine injection and/or thermal coagulation, and randomized to receive intravenous PPIs according to an intensive regimen (80 mg bolus followed by 8 mg/h as continuous infusion for 72 h) or a standard regimen (40 mg bolus daily followed by saline infusion for 72 h). After the infusion, all patients were given 20 mg PPI twice daily orally. The primary end point was the in-hospital rebleeding rate, as ascertained at the repeat endoscopy. RESULTS Bleeding recurred in 28 of 238 patients (11.8%) receiving the intensive regimen, and in 19 of 236 (8.1%) patients receiving the standard regimen (P= 0.18). Most rebleeding episodes occurred during the initial 72-h infusion: 18 (7.6%) and 19 events (8.1%) in the intensive and standard groups, respectively (P= 0.32). Mean units of blood transfused were 1.7 +/- 2.1 in the intensive and 1.5 +/- 2.1 in the standard regimen group (P= 0.34). The duration of hospital stay was <5 days for 88 (37.0%) and 111 patients (47.0%) in the intensive and standard groups (P= 0.03). There were fewer surgical interventions in the standard versus intensive regimen (1 vs 3). Five patients in each treatment group died. CONCLUSIONS Following endoscopic hemostasis of bleeding ulcers, standard-dose PPIs infusion was as effective as a high-dose regimen in reducing the risk of recurrent bleeding.

Abstract
BACKGROUND Drug use increases with advancing age, and in older patients it is associated with an increase in adverse drug reactions (ADRs). ADRs are a primary cause of morbidity and mortality worldwide. OBJECTIVES To evaluate the prevalence, clinical characteristics and avoidability of ADR-related hospital admissions in elderly patients. METHODS From November 2004 to December 2005, all patients aged >or=65 years consecutively admitted to the Geriatric Unit of the Casa Sollievo della Sofferenza Hospital, San Giovanni Rotondo in Italy, were evaluated for enrolment in the study. ADRs were defined according to the WHO Adverse Reaction Terminology system. Drugs were classified according to Anatomical Therapeutic Chemical classification system. The Naranjo algorithm was used to evaluate the relationship between drug use and the ADR (definite, probable, possible or doubtful) and Hallas criteria were used to evaluate the avoidability of the ADR (definitely avoidable, possibly avoidable or unavoidable). All cases of a suspected ADR were discussed by a team trained in drug safety, including three geriatricians, one clinical pharmacologist and one pharmacist. Only cases of an ADR with an agreement >or=80% were included. RESULTS Of the 1756 patients observed, 102 (5.8%, 42 males, 60 females, mean age 76.5 +/- 7.4 years, range 65-93 years) showed certain (6.8%) or probable (91.2%) ADR-related hospitalization. Gastrointestinal disorders (48 patients, 47.1%); platelet, bleeding and clotting disorders (20 patients, 19.6%); and cardiovascular disorders (13 patients, 12.7%) were the most frequent ADRs. NSAIDs (23.5%), oral anticoagulants (20.6%), low-dose aspirin (acetylsalicylic acid) [13.7%] and digoxin (12.7%) were the drugs most frequently involved in ADRs. Of the ADRs, 45.1% were defined as definitely avoidable, 31.4% as possibly avoidable, 18.6% as unavoidable and 4.9% as unclassifiable. Of 78 patients with definitely or possibly avoidable ADRs, 17 patients (21.8%) had received an inappropriate prescription, 29 patients (37.2%) had not received a prescription for an effective gastroprotective drug concomitantly with NSAID or low-dose aspirin treatment and 32 patients (41%) were not monitored during drug treatment. CONCLUSION In the elderly, almost 6% of hospitalizations are ADR related. Most of these ADRs are potentially avoidable. Strategies that reduce inappropriate prescriptions and monitoring errors, as well as improving active prevention of ADRs, are needed in elderly subjects.

Abstract
CRC development is a multi-step process that spans 10 to 15 years, thereby providing an opportunity for early detection and even prevention. The poor survival rate of advanced CRC has prompted the emphasis on prevention of this disease. CRC screening and removal of adenomas is an effective intervention, and is the cornerstone of prevention. However, screening efforts have had limited impact due to less than optimal compliance with guidelines. Chemoprevention involves the long-term use of a variety of oral agents that can delay, prevent or even reverse the development of adenomas in the large bowel, thus interfering with the multi-step progessing from adenoma to carcinoma. This effect is of particular importance to individuals with a hereditary prediposition to colorectal neoplasia and to those who are especially susceptile to the environmental causes of CRC. NSAIDs have drawn the most attention as chemoprevention agents. Sulindac and celecoxib are effective in promoting poly regression in high risk individuals with Familial Adenomatous Polyposis (FAP). In the more common sporadic setting the APROVe (refecoxib), APC and PreSAP (Celecoxib) trials have shown a significant reduction in adenoma recurrence but important concerns exist regarding cardiovascular toxicity associated with selective COX-2 inhibitors. These landmark studies are very important, as they provide a proof of concept that we can prevent high risk adenomas that can lead to CRC development. The ideal chemopreventive agent remains to be discovered with great emphasis on need not to harm. Possibly, combinations of agents will maximize effectiveness while limiting drug toxicity. Finally, personalized approaches will include the ability to predict risk and toxicity.

Abstract
BACKGROUND Over the past few years, major changes have taken place in the treatment of gastroduodenal peptic ulcer. AIM To evaluate risk factors associated with the incidence of peptic ulcer in inpatients. METHODS From 2001 to 2004, the number of prescriptions of H2-antagonists and proton pump inhibitors (PPIs) in each department of Verona University Hospital was monitored. Over the same period we prospectively recorded the number of upper endoscopies per department for inpatients with a diagnosis of peptic ulcer. RESULTS We analyzed 4943 inpatients. A significantly decreasing trend in H(2)-antagonist prescriptions (r=-0,88; P<0.001) and an increasing trend in PPI prescriptions (r=0.97; P<0.001) were observed. The endoscopic incidence of duodenal ulcers decreased linearly from 2001 to 2004 as follows: 6.5% (94/1439) in 2001, 5.6% (82/1473) in 2002, 4.5% (63/1411) in 2003, and 3.1% (22/702) (P<0.001) in 2004. Gastric ulcer incidence, sex, age, indication for endoscopy, use of nonsteroidal anti-inflammatory drugs (NSAIDs), presence of Helicobacter pylori (32%), and smoking and drinking habits showed no significant changes over the study period. Considering time-dependent variables, multivariate regression analysis identified only PPI use and NSAID use as factors predictive of duodenal ulcer but not of gastric ulcer. CONCLUSIONS In inpatients, PPIs are associated with a reduced risk of duodenal ulcer, whereas NSAIDs are associated with an increased risk. Gastric ulcer was not associated with any increased or degreased risk with the 2 above-mentioned variables.

Abstract
Meta-analyses of randomized, placebo-controlled trials of low-dose aspirin indicate that aspirin approximately doubles the risk of major GI bleeding compared with placebo. The risk in Japanese may possibly be higher compared to Western populations, although the evidence is still lacking and prospective studies are required. Prior GI events, older age, and use of other injurious medicines such as NSAIDs, anticoagulants, and corticosteroids seem to be factors associated with an increased risk for upper GI bleeding among aspirin users. Prospective studies are needed to identify specific risk factors for upper GI bleeding in Japanese patients taking low-dose aspirin. There are many potential gastroprotective drugs available in Japan, and studies are needed to assess the relative effectiveness of various strategies including PPI use for the prevention of aspirin-related upper GI ulcer complications and whether any of these other agents also provide protection against small bowel or colonic damage. Aspirin-induced enteropathy is now increasingly being recognized and is presumably not uncommon, and the availability of new imaging techniques for the small intestine and noninvasive tests such as fecal calprotectin should allow rapid progress in this important area.

Abstract
Proper management of Helicobacter pylori infection in clinical practice--when supported by evidence-based data--is expected to produce substantial cost-efficacy advantages. This consideration has prompted the Cervia Working Group to organise a meeting of experts to update the National Guidelines on the diagnosis and treatment of H. pylori infection in Italy. Recommendations in the new European Guidelines were considered in the National setting, here in the light of factors such as the incidence of gastric cancer and gastric lymphoma, the accessibility to different diagnostic tools, the prevalence of bacterial resistance against antibiotics, and the availability of different drugs. The main revisions in respect to the previous guidelines include H. pylori eradication in non-ulcer dyspepsia patients and in non-steroidal, anti-inflammatory drug users, as well as in patients with idiopathic thrombocytopenic purpura and iron deficiency anaemia. The stool antigen test is now accepted as a valid test for confirmation of H. pylori eradication following therapy. New therapeutic approaches have been recommended for both first- (sequential therapy) and second-line (levofloxacin-based) treatment in our country.

Abstract
OBJECTIVE To examine cyclooxygenase 2 inhibitor (coxib) utilization by rheumatologists for patients receiving nonsteroidal antiinflammatory drugs (NSAIDs) prior to the coxib market withdrawals. METHODS A prospective study of patients with rheumatoid arthritis enrolled in the Consortium of Rheumatology Researchers of North America registry was performed. RESULTS Of 1,833 patients receiving prescription NSAIDs, 1,380 (75.3%) received gastroprotection, defined as either coxib monotherapy and/or gastroprotective agent (GPA) cotherapy, and 1,207 (65.8%) received coxibs. The distribution of gastroprotective strategies included 860 (46.9%) patients who were prescribed coxib monotherapy, 347 (18.9%) prescribed dual coxib plus GPA cotherapy, 173 (9.4%) prescribed a nonselective NSAID (NS-NSAID) plus GPA cotherapy, and 453 (24.7%) prescribed an NS-NSAID without GPA cotherapy. For patients with 0, 1, and > or =2 identifiable gastrointestinal (GI) risk factors, coxib prescribing rates as a proportion of NSAID agents were 64.1%, 66.4%, and 68.6%, respectively; among dual aspirin/NSAID users, coxib prescribing rates were 66.2%, 78.3%, and 68.5% of NSAID prescriptions, respectively. CONCLUSION The majority of NSAID users were prescribed a gastroprotective strategy, primarily attributable to coxib utilization. Coxib utilization rates were consistently high across all levels of GI risk, including patients without identifiable risk factors. These data indicate that rheumatologists broadly adopted the coxib class of NSAIDs in a nonselective manner with respect to underlying GI risk and concomitant aspirin use. As novel therapeutic classes are introduced, early evaluation of prescribing patterns using arthritis registries can determine the appropriateness of prescribing patterns and may improve patient outcomes.

Abstract
BACKGROUND Helicobacter pylori eradication rates with triple therapies are decreasing, and few data in elderly patients are available. A 10-day sequential regimen succeeded in curing such H. pylori infection in unselected patients. AIM To compare this sequential regimen and the standard triple therapy for H. pylori eradication in geriatric patients with peptic ulcer. METHODS Overall, 179 H. pylori-infected patients with peptic ulcer were enrolled (mean age: 69.5 years; range: 65-83). Patients were randomized to 10-day sequential therapy (rabeprazole 20 mg b.d. plus amoxicillin 1 g b.d. for the first 5 days, followed by rabeprazole 20 mg, clarithromycin 500 mg and tinidazole 500 mg, all b.d., for the remaining 5 days) or standard 7-day triple regimen (rabeprazole 20 mg, clarithromycin 500 mg and amoxicillin 1 g, all b.d.). Helicobacter pylori status was assessed by histology and rapid urease test at baseline and 4-6 weeks after completion of treatment. RESULTS The sequential regimen achieved eradication rates significantly higher in comparison with the standard regimen at both intention-to-treat (94% vs. 80%; P = 0.008) and per-protocol (97% vs. 83%; P = 0.006) analyses. In both treatment groups, compliance to the therapy was high (> 95%), and the rate of mild side-effects was similarly low (< 12%). At repeated upper endoscopy, peptic ulcer lesions were healed in 97% patients, without a statistically significant difference between the sequential regimen and the standard triple therapy. CONCLUSIONS In elderly patients with peptic ulcer disease, the 10-day sequential treatment regimen achieved significantly higher eradication rates in comparison with standard triple therapy.
