Stop of proton-pump inhibitor treatment in patients with liver cirrhosis (STOPPIT): study protocol for a prospective, multicentre, controlled, randomized, double-blind trial

BackgroundProton-pump inhibitors (PPI) are liberally prescribed in patients with liver cirrhosis. Observational studies link PPI therapy in cirrhotic patients with an increased risk for infectious complications, hepatic encephalopathy and an increased risk for hospitalization and mortality. However, patients with liver cirrhosis are also considered to be at risk for peptic ulcer bleeding. The STOPPIT trial evaluates if discontinuation of a pre-existing PPI treatment delays a composite endpoint of re-hospitalization and/or death in patients (recently) hospitalized with liver cirrhosis compared to patients on continued PPI medication.MethodsThe STOPPIT-trial is a prospective, multicentre, randomized, double-blinded, placebo-controlled, parallel-group trial. In total, 476 patients with complicated liver cirrhosis who already receive long-term PPI therapy without evidence-based indication are 1:1 randomized to receive either esomeprazole 20 mg (control group) or placebo (intervention group) for 360 days. Patients with an indication for PPI therapy (such as a recent diagnosis of peptic ulcers, severe reflux esophagitis, severe hemorrhagic gastritis, recent endoscopic therapy for oesophageal varices) are excluded. The primary composite endpoint is the time-to re-hospitalization and/or death. Secondary endpoints include rates of re-hospitalization, mortality, occurrence of infections, hepatic decompensation and acute-on-chronic liver failure. The safety endpoint is defined as manifestation of an evidence-based indication for PPI re-therapy. The impact of PPI continuation or discontinuation on the intestinal microbiota will be studied. The recruitment will take place at 18 study sites throughout Germany. Recruitment has started in April 2021.DiscussionThe STOPPIT trial is the first clinical trial to study the effects of PPI withdrawal on relevant outcome variables in patients with complicated liver cirrhosis. If the hypothesis that PPI withdrawal improves clinical outcomes of cirrhosis patients is confirmed, this would argue for a strong restriction of the currently liberal prescription practice of PPIs in this population. If, on the other hand, the trial demonstrates an increased risk of gastrointestinal bleeding events in patients after PPI withdrawal, this could create a rationale for a more liberal, prophylactic PPI treatment in patients with liver cirrhosis.Trial registrationEU clinical trials register EudraCT 2019-005008-16 (registered December 27, 2019).

Association between short-term exposure to air pollution and peptic ulcer bleeding: A case-crossover study in China

BackgroundAir pollution has already become a serious public health concern worldwide, while evidence for the association between air pollution and digestive disease is not consistent. ObjectiveTo examine the association between air pollution and peptic ulcer bleeding (PUB). MethodsWe performed a time-stratified case-crossover study among 1,246,270 gastroscopy records in Zhejiang, China from January 1st, 2013 to June 30th, 2019. Individual exposure to air pollution for each subject was estimated by using data from 55 fixed-sites with an inverse distance weighted method. Conditional logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (95% CIs) for PUB associated with an interquartile range (IQR) increase in air pollution on the entire population. Subgroup analyses were performed for season, age and sex. ResultsTotally 3543 patients diagnosed with PUB were included in the analyses. Significant associations were observed between NO2, CO and PM2.5 and the risk of PUB. The effect was observed strongest measured as lag06 and an IQR increase of 7-day moving average concentrations of NO2 resulted in a 24.0% increase of getting PUB (95% CI: 2.6%–50.0%). SignificanceOur findings strengthen the hypothesis that short-term air pollution exposure has adverse health effects on digestive system.

Proton pump inhibitor use among patients at risk of peptic ulcer bleeding: a nationwide register-based study

Background Proton pump inhibitors reduce the risk of peptic ulcer bleeding in patients at risk. The knowledge about the extent of gastroprotection in patients at increased risk and factors associated with prophylactic treatment is limited. Aims (1) to analyze the extent of gastroprotective undertreatment in patients using aspirin/non-steroidal anti-inflammatory drugs and (2) to analyze which patient characteristics are associated with proton pump inhibitor prophylaxis among those at increased ulcer bleeding risk. Methods A Danish nationwide register-based study. Based on a risk stratification model we identified citizens at increased ulcer bleeding risk and analyzed the proportion concomitantly treated with proton pump inhibitors. Further, we analyzed associations between use of ulcer prophylaxis and comorbidity and socioeconomic characteristics. Results Some 44.4% of the high-risk patients were concomitantly treated with proton pump inhibitors. In the crude analyses cohabiting, having a high educational level and a high income were significantly associated with lower odds of being treated with proton pump inhibitors. When adjusting for medication use, age, sex and comorbidity the associations were insignificant. Conclusions There is room for improvement in the extent of ulcer prophylaxis but no clear social gradient in under prescribing of gastroprotection. With the substantial risk-reducing possibility concomitant proton pump inhibitor use could save numerous patients from ulcer bleeding each year. Our study calls for increased awareness of peptic ulcer bleeding risk and dissemination of knowledge to clinicians about risk factors for gastrointestinal hemorrhage and the risk reducing potential of co-prescribing proton pump inhibitors to patients at risk.

Anticoagulación luego de una hemorragia por úlcera péptica: riesgos de trombosis, mortalidad y sangrado recurrente

Background. Patients on chronic anticoagulation face a higher risk of peptic ulcer bleeding. In this setting, the risk-benefit equation of anticoagulation resumption remains undefined. Aims. To compare the risk of thrombosis and death between patients that resumed and did not resume anticoagulation after an index episode of peptic ulcer bleeding. The secondary objective was to compare time to re-bleeding between the groups. Methods. Retrospective cohort study of adult patients that suffered an index episode of peptic ulcer bleeding while on chronic anticoagulation. Patients were divided into two groups according to whether they resumed or not anticoagulation and were followed-up for one year. A multivariable, propensity score-adjusted Cox proportional hazards model was used to adjust for confounding. Adjusted survival curves were constructed. Results. 70 patients were included in the analysis; 64.3% were men. Median age at the time of PUB was 79 years (interquartile range (IQR): 72-83). Forty patients (57.1%) resumed anticoagulation after a median time of 15 days (IQR 5.25-41.75). Restarting anticoagulation was associated with a lower risk of thrombosis or death (hazard ratio [HR] 0.14; 95%CI 0.05-0.43) and did not increase the risk of recurrent bleeding significantly (HR 1.42; 95% CI 0.10-19.8). Conclusions. Resuming anticoagulation appears to reduce the hazard of thrombosis and death without increasing the risk of recurrent bleeding significantly.

Risk of Peptic Ulcer Bleeding Associated with Helicobacter pylori Infection, Nonsteroidal Anti-inflammatory Drugs, and Low-dose Aspirin Therapy in Peptic Ulcer Disease: A Case-control Study

Risk of Peptic Ulcer Bleeding Associated with Helicobacter pylori Infection, Nonsteroidal Anti-inflammatory Drugs, and Low-dose Aspirin Therapy in Peptic Ulcer Disease: A Case-control Study

Helicobacter pylori infection and the risk of upper gastrointestinal bleeding in low dose aspirin users: systematic review and meta-analysis.

To determine whether the risk of upper gastrointestinal bleeding in patients taking low dose aspirin (≤ 325 mg/day) is increased in people with Helicobacter pylori infections. A systematic search for all publications since 1989 (when H. pylori was named) using search term equivalents for "upper gastrointestinal haemorrhage" and "aspirin". Articles were assessed individually for inclusion of data on H. pylori infection, as not all relevant papers were indexed with this term. Data that could be pooled were then subjected to meta-analysis, using a random effects model. MEDLINE, Embase, Scopus, the Cochrane Library. Of 7599 retrieved publications, reports for seven case-control studies contained data suitable for meta-analysis; four were deemed high quality on the Newcastle-Ottawa scale. Upper gastrointestinal haemorrhage was more frequent in aspirin users infected with H. pylori than in those who were not (odds ratio [OR], 2.32; 95% CI, 1.25-4.33; P = 0.008). The heterogeneity of the studies was significant (Q = 19.3, P = 0.004; I2 = 68.9%, 95% CI, 31.5-85.9%), but the pooled odds ratio was similar after removing the two studies that contributed most to heterogeneity (OR, 2.34; 95% CI, 1.56-3.53; P < 0.001). The number needed to treat to prevent one bleeding event annually was estimated to be between 100 and more than 1000. The odds of upper gastrointestinal bleeding in patients taking low dose aspirin is about twice as great in those infected with H. pylori. Testing for and treating the infection should be considered in such patients, especially if their underlying risk of peptic ulcer bleeding is already high.

Prevention of post-sphincterotomy bleeding by proton pump inhibitor: A randomized controlled trial.

Post-endoscopic sphincterotomy (EST) bleeding is one of the most frequent complications of endoscopic retrograde cholangiopancreatography (ERCP). Although the use of proton pump inhibitors (PPIs) reduces the risk of peptic ulcer bleeding, their role in preventing EST bleeding has not been evaluated. This study aimed to assess the use of pre-emptive PPIs in patients undergoing EST. This was an investigator-initiated, open-label, randomized study. Consecutive patients scheduled to undergo ERCP and EST were enrolled after excluding those who had previous EST or used acid-suppression agents. Eligible patients were randomized to receive either PPI or standard care. The PPI group received intravenous esomeprazole 4 h before the EST and then every 12 h for 1 day, followed by high-dose oral esomeprazole for 10 days. All patients were followed up for 30 days. The primary outcome was the proportion of patients with combined immediate and delayed overt post-EST bleeding. Altogether 125 patients (60 in the PPI arm and 65 in the standard care arm) who had undergone EST were analyzed. Immediate bleeding was noted in nine (15.0%) patients in the PPI group and four (6.2%) in the standard care group (P = 0.14). Overt delayed post-EST bleeding was seen in two (3.3%) and five (7.7%) patients in PPI and standard care arms, respectively (P = 0.44). There were no significant differences in other outcomes, including a decrease in hemoglobin of >20 g/L, the need for blood transfusion, length of hospital stay and 30-day mortality. Pre-emptive PPI did not reduce the risk of post-EST bleeding.

Contribution of Helicobacter pylori infection to the risk of peptic ulcer bleeding in patients on nonsteroidal anti-inflammatory drugs, antiplatelet agents, anticoagulants, corticosteroids and selective serotonin reuptake inhibitors.

Nonsteroidal anti-inflammatory drugs, low-dose aspirin, non-aspirin antiplatelet agents, anticoagulants, selective serotonin reuptake inhibitors and corticosteroids increase the risk of gastroduodenal bleeding. To determine in a retrospective cohort study the contribution of Helicobacter pylori infection to the risk of peptic ulcer bleeding in patients taking these drugs. Among patients with peptic ulcer disease diagnosed by endoscopy from 01/2004 to 12/2014 (N=1719, 60% males, age 65.8±14.5), 56.9% had peptic ulcer bleeding (cases) and 43.1% uncomplicated peptic ulcer disease (controls). Demographics, intake of nonsteroidal anti-inflammatory drugs, aspirin, non-aspirin antiplatelet agents, anticoagulants, selective serotonin reuptake inhibitors, proton pump inhibitors and corticosteroids were documented. H.pylori status was determined by histology, rapid urease test or serology. Adjusted odds ratios (OR) were estimated by logistic regression analysis. Helicobacter pylori infection increased the risk of peptic ulcer bleeding in nonsteroidal anti-inflammatory drug and aspirin users (OR=2.91, 95% CI=1.71-4.98 and OR=2.23, 95% CI=1.52-3.28, respectively), but not in patients on anticoagulants, selective serotonin reuptake inhibitor or corticosteroid therapy. H.pylori-positive status substantially increased the risk of peptic ulcer bleeding in patients on non-aspirin antiplatelet agents (OR=4.37, 95% CI=1.28-14.99), concomitant aspirin/nonsteroidal anti-inflammatory drug intake (OR=5.85, 95% CI=1.68-20.36) and combined antiplatelet therapy (OR=8.43, 95% CI=1.09-65.17). After further adjustment for proton pump inhibitor intake, H.pylori infection was still a risk factor for peptic ulcer bleeding in nonsteroidal anti-inflammatory drug and aspirin users. Helicobacter pylori infection increases the risk of peptic ulcer bleeding in peptic ulcer disease patients on nonsteroidal anti-inflammatory drugs, aspirin and non-aspirin antiplatelet agents. H.pylori-positive patients on combined antiplatelet therapy carry the highest risk for peptic ulcer bleeding.

Higher risk of peptic ulcer bleeding with NSAIDs ± GCs

Higher risk of peptic ulcer bleeding with NSAIDs ± GCs

Glucocorticoids and the Risk of Peptic Ulcer Bleeding: Case-Control Analysis Based on Swiss Claims Data.

Controversy exists as to whether glucocorticoids (GC) are ulcerogenic per se and may thus cause peptic ulcer bleeding (PUB) independent of concomitantly prescribed nonsteroidal anti-inflammatory drugs (NSAIDs). To investigate the association between GC use and PUB with or without co-medication with NSAIDs. We conducted a case-control study using administrative claims data from the Swiss health insurance company Helsana. We identified 1191 cases with incident PUB between 2012 and 2016 and matched up to 10 PUB-free controls to each case on age, sex, region and number of years insured with Helsana. We compared prior GC exposure between cases and controls using multivariate conditional logistic regression analyses controlling for several potential confounders. Patients with or without concomitant NSAID exposure were analysed separately. Patients with prior exposure to both GC and NSAIDs were five times more likely to experience PUB than patients who neither used GC nor NSAIDs (adjusted odds ratio [adj. OR] 4.80, 95% CI 3.55-6.71). Although the risk of PUB among patients who used NSAIDs without GC was increased threefold (adj. OR 3.20, 95% CI 2.59-3.95), we observed only a moderately increased risk among patients who used GC alone without NSAIDs (adj. OR 1.63, 95% CI 1.20-2.42). The use of NSAIDs with or without GC was associated with a markedly higher risk of PUB compared with GC monotherapy. Use of GC alone was associated with a moderately increased risk of PUB, which might be causal or attributed to confounding by indication.

Association between emergency admission for peptic ulcer bleeding and air pollution: a case-crossover analysis in Hong Kong's elderly population

Air pollution increases intestinal permeability, alters the gut microbiome, and promotes inflammation, which might contribute towards gastrointestinal bleeding. In the present study, we aim to examine whether short-term elevations in air pollution are associated with increased numbers of emergency hospital admissions for peptic ulcer bleeding in Hong Kong. Daily air pollution (particulate matter with aerodynamic diameter less than 2·5 μm [PM2·5], nitric oxide [NO2], sulpher dioxide [SO2], and ozone [O3]) data during 2005-10 were collected from the Environmental Protection Department and emergency admission data for peptic ulcer bleeding in elderly people (aged 65 years or older) from the Hospital Authority of Hong Kong. A time stratified case-crossover analysis with conditional logistic regression was used to estimate the excess risk of peptic ulcer bleeding associated with each air pollutant, in single-pollutant and multi-pollutant models. Cardiorespiratory diseases were used as positive controls. 8566 emergency admissions for peptic ulcer bleeding were recorded among Hong Kong's elderly population during 2005-10; the daily number of admissions ranged from 0 to 13. An IQR increment of 5-day moving average (lag04) of NO2 concentration (25·8 μg/m3) was associated with a 7·6% (95% CI 2·2-13·2) increase in emergency admissions for peptic ulcer bleeding. Multi-pollutant models confirmed the robustness of the risk estimates for NO2. Other pollutants (PM2·5, SO2, and O3) were not associated with peptic ulcer bleeding admissions. Short-term elevation in ambient NO2 might trigger peptic ulcer bleeding events and increase the risk of emergency admissions for peptic ulcer bleeding in Hong Kong's elderly population. These findings strengthen the hypothesis that air pollution affects not just cardiopulmonary diseases, but also certain diseases of the digestive system. None.

Immunosuppressive agents are associated with peptic ulcer bleeding.

Peptic ulcer bleeding can be fatal. Non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids and immunosuppressive agents are administered for long-term usage. The present study assessed the association between peptic ulcer bleeding and administration of NSAIDs, corticosteroids and immunosuppressive agents. Furthermore, the efficacy of lowering the risk of peptic ulcer bleeding with proton pump inhibitors (PPI) and histamine 2 receptor antagonists (H2RA) was evaluated. Medical records were retrospectively analyzed for patients subjected to an upper gastrointestinal (GI) endoscopy performed at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) from October 2014 to September 2015. During this period, a total of 1,023 patients underwent an upper GI endoscopy. A total of 1,023 patients, including 431 males (age, 68.1±12.9 years) and 592 females (age, 66.4±12.3 years), who had been administered NSAIDs, corticosteroids, immunosuppressive agents, PPIs and H2RAs, were respectively enrolled. Endoscopic findings of the patients were reviewed and their data were statistically analyzed. Logistic regression analysis was used to determine the odds ratio of peptic ulcer bleeding for each medication; immunosuppressive agents had an odds ratio of 5.83, which was larger than that for NSAIDs (4.77). The Wald test was applied to confirm the correlation between immunosuppressive agents and peptic ulcer bleeding. Furthermore, χ2 tests were applied to the correlation between peptic ulcer bleeding and administration of PPIs or H2RAs. Immunosuppressive agents had the largest χ2, and the P-value was 0.03. Administration of PPIs was significantly correlated with non-peptic ulcer bleeding (P=0.02); furthermore, a tendency toward non-peptic ulcer bleeding with administration of H2RA was indicated, but it was not statistically significant (P=0.12). In conclusion, immunosuppressive agents were correlated with peptic ulcer bleeding and PPIs were effective at lowering the risk of peptic ulcer bleeding.

Chronic obstructive pulmonary disease is associated with increased recurrent peptic ulcer bleeding risk

BackgroundThe association between chronic obstructive pulmonary disease (COPD) and the risk of recurrent peptic ulcer bleeding (PUB) remains unclear. In this study, we compared the risk of recurrent PUB between patients with and those without COPD. MethodsUsing the Taiwan National Health Insurance Research Database, we first selected patients newly diagnosed with PUB in 2002–2009. Two groups comprising 13,732 COPD cases and 13,732 non-COPD matched controls were created using propensity score matching, thereby making the differences in basic demographics, medication use, and disease conditions between the two groups negligible. Cox proportional hazard regression was used to evaluate the risk of recurrent PUB during the follow-up period. ResultsThe cumulative recurrence rate of PUB was significantly higher in the patients with COPD than in the non-COPD matched controls (2years: 10.8% vs 9.3%; 6years: 18.3% vs 15.7%, P all <0.05), with an adjusted hazard ratio (HR) of 1.17 (95% confidence interval [CI], 1.08–1.26, P<0.001) and 1.19 (95% CI, 1.12–1.26, P<0.001) within 2-year and 6-year follow-ups, respectively. Patients with COPD using steroids were at a marginally higher risk of recurrent PUB than those who did not use steroids. Multivariate stratified analysis revealed similar results in many subgroups. ConclusionsThe risk of recurrent PUB is higher in patients with COPD than in patients without COPD.

Early eradication has a lower risk of peptic ulcer bleeding in Helicobacter pylori-infected chronic kidney disease patients

BackgroundEnd stage renal disease (ESRD) contributes to a higher mortality rate in peptic ulcer bleeding (PUB) patients. A crucial question is whether early Helicobacter pylori (H. pylori) eradication therapy is necessary for H. pylori-infected chronic kidney disease (CKD) patients. To explore whether H. pylori eradication therapy has a lower risk of PUB at the pre-ESRD stage than at the ESRD stage. Methods and patientsPatients meeting 2 criteria were defined as newly diagnosed ESRD cases: (1) patients diagnosed with ESRD and receiving regular dialysis between 2000 and 2009; and (2) patients with no history of dialysis between 1997 and 1999. We divided the study participants into pre-ESRD and ESRD groups on the basis of the time between H. pylori eradication and dialysis. The date of the first PUB diagnosis was defined as the primary endpoint. Stratified Cox proportional hazard regression analysis was used to estimate the effect of H. pylori eradication at the pre-ESRD and ESRD stage on the occurrence of PUB. ResultsWe included 476 patients in the pre-ESRD cohort and 476 patients in the matched ESRD cohort. After adjustment for age, sex, the presence of comorbidities, and medication use, the hazard ratio of PUB was 0.66 times less in the pre-ESRD cohort than in the ESRD cohort. Factors such as Charlson's score more than 3, and nonsteroidal anti-inflammatory drugs were associated with an increased risk of PUB. ConclusionOur result supports that early H. pylori eradication has a lower risk of PUB in H. pylori-infected CKD patients.

Higher Risk of Developing Peptic Ulcer Bleeding in Adult Patients Diagnosed with Hypoalbuminemia

Aim: To evaluate whether patients diagnosed with hypoalbuminemia have higher risk of developing peptic ulcer bleeding (PUB). Background: Low serum albumin levels are particularly common in critically ill patients. Life-threatening upper gastrointestinal (UGI) hemorrhage is a stress-related mucosal injury or stress ulceration in critically ill patients. Patients and methods: We conducted a retrospective cohort study from the 2000–2010 database records of Taiwan’s Bureau of National Health Insurance. Hypoalbuminemia patients were defined at least one of the inpatient claims with a diagnosis defined using ICD-9-CM diagnosis code: 273.8. To be defined as a non-hypoalbuminemic, a person cannot have the code ICD-9-CM: 273.8 in their inpatient records or in the ambulatory care claims. The primary endpoint was hospitalization for PUB. We used a Cox’s proportional-hazards model to estimate the risk of PUB in hypoalbuminemia patients. Results: We enrolled 3,197 mild hypoalbuminemia patients, 490 severe hypoalbuminemia patients, and 14,748 non-hypoalbuminemia patients from 2000 to 2010. After adjusting for possible confounders, results indicated that the mild hypoalbuminemia group (HR=1.75, p<0.001) and severe hypoalbuminemia (HR=2.80, p< 0.001) had a higher hospitalization rate for PUB, compared with the non-hypoalbuminemia group. Furthermore, non-steroidal antiinflammatory drugs use were critical risk factors for PUB in mild and severe hypoalbuminemia patients. Conclusions: Patients diagnosed with hypoalbuminemia have a significantly elevated risk of developing PUB. Even though albumin normalizes after discharge, more attention should be paid to reduce the PUB risk in patients diagnosed with hypoalbuminemia.

Glucocorticoids: increased risk of peptic ulcer bleeding

Glucocorticoids: increased risk of peptic ulcer bleeding

Short-term use of glucocorticoids and risk of peptic ulcer bleeding: a nationwide population-based case-crossover study.

Controversy exists regarding glucocorticoids therapy and the risk of peptic ulcer bleeding (PUB). The present study was undertaken to determine whether short-term use ofglucocorticoids is associated with the occurrence of peptic ulcer bleeding. The records of adult patients hospitalised for newly diagnosed peptic ulcer bleeding from 2000 to 2012 were retrieved from the Taiwan National Health Insurance Research Database, a nationwide population-based registry system. The association between systemic glucocorticoids usage and peptic ulcer bleeding was determined with a conditional logistic regression model comparing cases and controls during time windows of 7, 14 and 28days using a case-crossover design. Of the 8894 enrolled patients, the adjusted self-matched odds ratios for peptic ulcer bleeding after exposure to the glucocorticoids were 1.37 (95% CI: 1.12-1.68, P=0.003) for the 7-day window, 1.66 (95% CI: 1.38-2.00, P<0.001) for the 14-day window and 1.84 (95% CI: 1.57-2.16, P<0.001) for the 28-day window. Moderate to high, but not low dose glucocorticoids (methylprednisolone <4mg/day or its equivalence) were associated with an increased risk of peptic ulcer bleeding. Concomitant use of a nonselective nonsteroidal anti-inflammatory drug (NSAID) or aspirin further elevated the risk. However, it does not eliminate the effect of underlying diseases flare-up that may have placed the patients at risk for peptic ulcer bleeding in this kind of study design. Short-term (7-28days) exposure to glucocorticoids is significantly associated with peptic ulcer bleeding; this risk seems dose-dependent and is higher when nonselective NSAIDs or aspirin are used concurrently.

Peptic Ulcer Bleeding Risk. The Role of Helicobacter Pylori Infection in NSAID/Low-Dose Aspirin Users.

Helicobacter pylori (H. pylori) infection and NSAID/low-dose aspirin (ASA) use are associated with peptic ulcer disease. The risk of peptic ulcer bleeding (PUB) associated with the interaction of these factors remains unclear. The objective of this study was to determine the risk of PUB associated with the interaction between H. pylori infection and current nonsteroidal anti-inflammatory drugs (NSAIDs) or low-dose ASA use. This was a case-control study of consecutive patients hospitalized because of PUB. Controls were matched by age, sex, and month of admission. H. pylori infection status was determined in all cases and controls by serology. Drug use was determined by structured questionnaire. Adjusted relative risk (RR) associated with different factors, and the interaction between NSAID/ASA and H. pylori infection was estimated by logistic regression analysis. The study included 666 cases of PUB and 666 controls; 74.3% cases and 54.8% controls (RR: 2.6; 95% confidence interval (CI): 2.0-3.3) tested positive for H. pylori infection; 34.5% of cases had current NSAID use compared with 13.4% of controls (RR: 4.0; 95% CI: 3.0-5.4). Respective proportions for low-dose ASA use were 15.8 and 12%, respectively (RR: 1.9; 95% CI: 1.3-2.7). The RR of PUB for concomitant NSAID use and H. pylori infection suggested an additive effect (RR: 8.0; 95% CI: 5.0-12.8), whereas no interaction was observed with ASA use (RR: 3.5; 95% CI: 2.0-6.1). NSAID, low-dose ASA use, and H. pylori infection are three independent risk factors for the development of PUB, but there were differences in the interaction effect between low-dose ASA (no interaction) or NSAID (addition) use and H. pylori infection, which may have implications for clinical practice in prevention strategies.

Risk of peptic ulcer bleeding associated with Helicobacter pylori infection, nonsteroidal anti‐inflammatory drugs, low‐dose aspirin, and antihypertensive drugs: A case‐control study

The associations between antithrombotic or antihypertensive drugs and peptic ulcer bleeding (PUB) remain unknown, particularly in Asia, where Helicobacter pylori infection is prevalent. This study aims to evaluate the risks of PUB from antithrombotic drugs, angiotensin II receptor blockers (ARBs), angiotensin-converting enzyme (ACE) inhibitors, calcium channel blockers, α-blockers, and β-blockers. This prospective hospital-based case-control study included 230 patients with endoscopically verified PUB and 920 age and sex-matched controls (1:4) without bleeding on screening endoscopy. Adjusted odds ratios (AOR) for the risk of PUB were determined by conditional logistic regression analysis. In multivariate analysis, alcohol consumption (AOR, 2.2; P < 0.001), history of peptic ulcer (AOR, 4.8; P < 0.001), H. pylori infection (AOR, 2.1; P < 0.001), comorbidity index (AOR, 1.1; P = 0.089), nonsteroidal anti-inflammatory drugs (NSAIDs) (AOR, 2.0; P = 0.025), and low-dose aspirin (AOR, 2.8; P = 0.003) increased the risk of PUB, whereas H. pylori eradication (AOR, 0.03; P < 0.001), proton pump inhibitors (PPIs) (AOR, 0.1; P < 0.001), and histamine 2-receptor antagonists (H2RA) (AOR, 0.1; P < 0.001) reduced it. No significant interactions were observed between H. pylori infection and NSAIDs use for PUB (P = 0.913). ARBs (P = 0.564), ACE inhibitors (P = 0.213), calcium channel blockers (P = 0.215), α-blockers (P = 0.810), and β-blockers (P = 0.864) were not associated with PUB. We found that alcohol consumption, history of peptic ulcer, H. pylori infection, NSAIDs use, and low-dose aspirin use were independent risk factors for PUB, whereas H. pylori-eradication, PPIs use, and H2RA use reduced its risk. Interactions between H. pylori and NSAIDs use in PUB were not observed. No antihypertensive drug was associated with PUB.
