Abstract Background Proton pump inhibitors (PPIs) are frequently prescribed to patients with coronary heart disease (CHD) under antiplatelet therapy to prevent gastrointestinal (GI) bleeding. However, its clinical impact is still under debate, especially in Asian population. This study was undertaken to explore the effects of concurrent use of clopidogrel and PPIs on the clinical outcomes in Chinese patients with CHD in secondary prevention. Methods A single-center retrospective study was conducted in 638 patients with CHD on consecutive clopidogrel therapy for at least 1 year. After 18-month follow-up, adverse clinical events were collected. Cox regression was used to calculate hazard ratios (HR) and 95% confidence interval (CI) for the effect of PPI use on the outcomes. A total of 638 patients were recruited from 2014 to 2015 in this study, among whom 201 were sustained PPI users, 188 were intermittent PPI users and the remaining 249 were non-PPI users. Results Compared with sustained PPI users, intermittent use of PPIs was associated with a lower risk of stroke, major adverse cardiac events (MACE) and net adverse clinical event (NACE) (stroke: adjusted HR: 0.109, 95% CI 0.014–0.878, p = 0.037; MACE: adjusted HR: 0.293, 95% CI 0.119–0.722; p = 0.008; NACE: adjusted HR: 0.357, 95% CI 0.162–0.786, p = 0.011). Subgroup analysis further revealed the benefit of intermittent PPI use was significant in male CHD patients over 60 years old, with hypertension or chronic kidney disease, and undergoing percutaneous coronary intervention during hospitalization. Conclusion The current findings suggest that the intermittent concurrent use of PPIs and clopidogrel is not associated with an increased risk of 18-month adverse clinical outcomes, and intermittent use of PPIs is associated with a lower rate of MACE and NACE.

ObjectiveThe benefit of continuing 5-aminosalicylate (5-ASA) in patients with ulcerative colitis (UC) who initiate anti-tumour necrosis factor-alpha (anti-TNF) biologics is unknown. We aimed to compare clinical outcomes in patients with UC already on 5-ASA who started anti-TNF and then either stopped or continued 5-ASA.DesignOur primary outcome was any adverse clinical event defined as a composite of new corticosteroid use, UC-related hospitalisation or surgery. We used two national databases: the United States (US) Truven MarketScan health claims database and the Danish health registers. Patients with UC who started anti-TNF after having been on oral 5-ASA for at least 90 days were included. Patients were classified as stopping 5-ASA if therapy was discontinued within 90 days of starting anti-TNF. We performed multivariable Cox regression models controlling for demographics, clinical factors and healthcare utilisation. Adjusted HRs (aHR) with 95% CI are reported comparing stopping 5-ASA with continuing 5-ASA.ResultsA total of 3589 patients with UC were included (2890 US and 699 Denmark). Stopping 5-ASA after initiating anti-TNF was not associated with an increased risk of adverse clinical events in the U.S. cohort (aHR 1.04; 95% CI 0.90 to 1.21, p=0.57) nor in the Danish cohort (aHR 1.09; 95% CI 0.80 to 1.49, p=0.60). Results were similar in sensitivity analyses investigating concomitant immunomodulator use and duration of 5-ASA treatment before initiating anti-TNF.ConclusionIn two national databases, stopping 5-ASA in patients with UC starting anti-TNF therapy did not increase the risk of adverse clinical events. These results should be validated in a prospective clinical trial.

Background: Proton-pump inhibitors (PPIs) are commonly used in clinical practice for gastric acid suppression. However, these agents have also been associated with certain negative clinical outcomes. We evaluated the real-world effects of incident PPI use on clinical outcomes in patients with Staphylococcus aureus bacteremia. Methods: This retrospective cohort study included patients admitted to Veterans Affairs hospitals with positive S. aureus blood cultures collected between 2002 and 2013 that received appropriate antibiotics within 48 hours of culture collection. Clinical outcomes among three PPI exposure groups, each compared to nonusers, were assessed with propensity-score-matched Cox proportional-hazard regression models: pretreated PPI users initiating therapy in the 30 days prior to culture and either (a) continuing PPI therapy after culture, or (b) not continuing after culture, and (c) de novo users initiating at culture. Results: Clinical outcomes, including inpatient mortality, intensive care discharge, 30-day mortality, 30-day readmission, and 30-day Clostridium difficile infection (CDI) were similar among PPI users and nonusers. Though length of stay was longer in pretreated, continuing PPI users [time-to-discharge hazard ratio (HR) 0.78, 95% confidence interval (CI) 0.65–0.93], 14-day mortality was significantly lower than in nonusers (HR 0.66, 95% CI 0.50–0.87). Conclusions: In our large national cohort study, PPIs were not associated with an increased risk of negative clinical outcomes, including mortality and CDI, in patients with S. aureus bacteremia.

ObjectiveThe adverse effects of proton pump inhibitors (PPIs) have been documented for pneumonia; however, there is no consensus regarding whether the use of PPIs might be harmful regarding the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In this regard, we aimed to measure the potential associations of the current use of PPIs with the infection rates of COVID-19 among patients who underwent SARS-CoV-2 testing.DesignData were derived from a Korean nationwide cohort study with propensity score matching. We included 132 316 patients older than 18 years who tested for SARS-CoV-2 between 1 January and 15 May 2020. Endpoints were SARS-CoV-2 positivity (primary) and severe clinical outcomes of COVID-19 (secondary: admission to intensive care unit, administration of invasive ventilation or death).ResultsIn the entire cohort, there were 111 911 non-users, 14 163 current PPI users and 6242 past PPI users. After propensity score matching, the SARS-CoV-2 test positivity rate was not associated with the current or past use of PPIs. Among patients with confirmed COVID-19, the current use of PPIs conferred a 79% greater risk of severe clinical outcomes of COVID-19, while the relationship with the past use of PPIs remained insignificant. Current PPI use starting within the previous 30 days was associated with a 90% increased risk of severe clinical outcomes of COVID-19.ConclusionPatients taking PPIs are at increased risk for severe clinical outcomes of COVID-19 but not susceptible to SARS-CoV-2 infection. This suggests that physicians need to assess benefit–risk assessments in the management of acid-related diseases amid the COVID-19 pandemic.

ObjectivesThis study aimed to assess whether the combined use of proton pump inhibitors (PPIs) with non-steroidal anti-inflammatory drugs (NSAIDs) or antibiotics (penicillins, macrolides, cephalosporins or fluoroquinolones) was associated with an increased risk of acute kidney injury (AKI).DesignA nested case–control study.SettingA health insurance claims database constructed by the Japan Medical Data Center.ParticipantsPatients were eligible if they were prescribed a PPI, NSAID and antibiotic at least once between January 2005 and June 2017. The patients who were new PPI users and did not have any history of renal diseases before cohort entry were included (n=219 082). The mean age was 45 and 44% were women.InterventionsCurrent use of PPIs, NSAIDs, or antibiotics.Primary outcome measuresAcute kidney injury.ResultsDuring a mean follow-up of 2.4 (SD, 1.7) years, 317 cases of AKI were identified (incidence rate of 6.1/10 000 person-years). The current use of PPIs was associated with a higher risk of AKI compared with past PPI use (unadjusted OR, 4.09; 95% CI, 3.09 to 5.44). The unadjusted ORs of AKI for the current use of PPIs with NSAIDs, cephalosporins and fluoroquinolones, compared with the current use of PPIs alone, were 3.92 (95% CI, 2.40 to 6.52), 2.57 (1.43 to 4.62) and 3.08 (1.50 to 6.38), respectively. The effects of concurrent use of PPIs with NSAIDs, cephalosporins or fluoroquinolones remain significant in the adjusted model. The analyses on absolute risk of AKI confirmed the results from the nested case–control study.ConclusionsConcomitant use of NSAIDs with PPIs significantly increased the risk for AKI. Moreover, the results suggested that concomitant use of cephalosporins or fluoroquinolones with PPIs was associated with increased risk of incident AKI.

Introduction: We sought to investigate the association between hemoglobin (Hgb) changes in patients with ADHF (with and without PACs) to mortality and clinical outcomes. Methods: We examined 433 patients enrolled in the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE) trial. Change of Hgb (g/dL) was defined as at least 1 (g/dL) drop by hospital discharge. Quartiles of % change of Hgb (g/dL) were calculated. We used multivariable Cox regression analysis to evaluate the effect Hgb change on mortality and composite end points of death, cardiac re-hospitalization, or cardiac transplant. Results: Of the 433 patients, 324 (75%) had baseline and discharge Hgb available for analysis. Of those, 64 (20%) had at least 1 (g/dL) drop of Hgb by time of discharge. Patients in the Hgb drop group were older than those without Hgb changes (59 vs. 55, p = 0.011). There were no baseline differences in gender, race, and etiology of HF between groups. Compared to patients without Hgb changes, patients with Hgb drop had lower systolic BP (99 vs. 106, p = 0.017), lower sodium (136 vs. 137, p =0.025), higher BUN (37 vs. 26, p <0.001), and higher Creatinine (1.6 vs. 1.3, p <0.001), respectively. Higher Hgb drop was observed in the PACs (vs. no PACs) randomized arm of the trial (2 g/dL: PACs 10% versus 3%, p =0.010; 3 g/dL: PACs 5% versus 0%, p =0.005). After adjustments, higher in-hospital Hgb was associated with lower mortality (HR 0.79, p =0.003). In addition, patients in the Hgb drop group had increased risk of mortality (Adjusted HR 2.38, p =0.003) and composite endpoints (Adjusted HR 1.43, p =0.055). PACs insertion was not associated with adverse clinical outcomes by quartiles of % change of hemoglobin (Mortality: Q1: HR 0.80, p 0.601, Q2 HR 0.79, p = 0.706, Q3 HR 0.34, p =0.101, Q4 HR 2.23, p =0.357). Conclusion: In-hospital decrease in Hgb is independently associated with increased long-term mortality and adverse cardiovascular events in severe HF. The ideal Hgb levels in ADHF patients should be investigated and the insertion of PACs to direct therapy should be weighed against bleeding risks.
