RESUMO

INTRODUCTION: The periprocedural management of patients with atrial fibrillation (AF) using a direct oral anticoagulant (DOAC) undergoing elective gastrointestinal (GI) endoscopic procedure remains uncertain. We investigated the safety of a standardized periprocedural DOAC management strategy. METHODS: The Periprocedural Anticoagulation Use for Surgery Evaluation cohort study enrolled adult patients receiving a DOAC (apixaban, rivaroxaban, or dabigatran) for AF scheduled for an elective procedure or surgery. This analysis addresses patients undergoing digestive endoscopy. Standardized periprocedural management consisted of DOAC interruption 1 day preendoscopy with resumption 1 day after procedure at low-moderate risk of bleeding or 2 days in case of a high bleeding risk. Thirty-day outcomes included GI bleeding, thromboembolic events, and mortality. RESULTS: Of 556 patients on a DOAC (mean [SD] age of 72.5 [8.6] years; 37.4% female; mean CHADS 2 score 1.7 [1.0]), 8.6% were also on American Society of Anesthesiology (ASA) and 0.7% on clopidogrel. Most of the patients underwent colonoscopies (63.3%) or gastroscopies (14.0%), with 18.9% having both on the same procedural day. The mean total duration of DOAC interruption was 3.9 ± 1.6 days. Four patients experienced an arterial thromboembolic event (0.7%, 0.3%-1.8%) within 24.2 ± 5.9 days of DOAC interruption. GI bleeding events occurred in 2.5% (1.4%-4.2%) within 11.1 ± 8.1 days (range: 0.6; 25.5 days) of endoscopy, with major GI bleeding in 0.9% (0.4%-2.1%). Three patients died (0.5%; 0.2%-1.6%) 15.6-22.3 days after the endoscopy. DISCUSSION: After a contemporary standardized periprocedural management strategy, patients with AF undergoing DOAC therapy interruption for elective digestive endoscopy experienced low rates of arterial thromboembolism and major bleeding.

RESUMO

We conducted systematic reviews of predefined clinical questions and used the Grading of Recommendations, Assessment, Development and Evaluations approach to develop recommendations for the periendoscopic management of anticoagulant and antiplatelet drugs during acute gastrointestinal (GI) bleeding and the elective endoscopic setting. The following recommendations target patients presenting with acute GI bleeding: For patients on warfarin, we suggest against giving fresh frozen plasma or vitamin K; if needed, we suggest prothrombin complex concentrate (PCC) compared with fresh frozen plasma administration; for patients on direct oral anticoagulants (DOACs), we suggest against PCC administration; if on dabigatran, we suggest against the administration of idarucizumab, and if on rivaroxaban or apixaban, we suggest against andexanet alfa administration; for patients on antiplatelet agents, we suggest against platelet transfusions; and for patients on cardiac acetylsalicylic acid (ASA) for secondary prevention, we suggest against holding it, but if the ASA has been interrupted, we suggest resumption on the day hemostasis is endoscopically confirmed. The following recommendations target patients in the elective (planned) endoscopy setting: For patients on warfarin, we suggest continuation as opposed to temporary interruption (1-7 days), but if it is held for procedures with high risk of GI bleeding, we suggest against bridging anticoagulation unless the patient has a mechanical heart valve; for patients on DOACs, we suggest temporarily interrupting rather than continuing these; for patients on dual antiplatelet therapy for secondary prevention, we suggest temporary interruption of the P2Y12 receptor inhibitor while continuing ASA; and if on cardiac ASA monotherapy for secondary prevention, we suggest against its interruption. Evidence was insufficient in the following settings to permit recommendations. With acute GI bleeding in patients on warfarin, we could not recommend for or against PCC administration when compared with placebo. In the elective periprocedural endoscopy setting, we could not recommend for or against temporary interruption of the P2Y12 receptor inhibitor for patients on a single P2Y12 inhibiting agent. We were also unable to make a recommendation regarding same-day resumption of the drug vs 1-7 days after the procedure among patients prescribed anticoagulants (warfarin or DOACs) or P2Y12 receptor inhibitor drugs because of insufficient evidence.

RESUMO

BACKGROUND & AIMS: The safety of different antithrombotic strategies for patients with 1 or more indication for antithrombotic drugs has not been determined. We investigated the risk and time frame for gastrointestinal bleeding (GIB) in patients prescribed different antithrombotic regimens. We proposed that risk would increase over time and with combination regimens, especially among elderly patients. METHODS: We performed a retrospective analysis of nationwide claims data from privately insured and Medicare Advantage enrollees who received anticoagulant and/or antiplatelet agents from October 1, 2010, through May 31, 2017. Patients were stratified by their prescriptions (anticoagulant alone, antiplatelet alone, or a combination) and by their primary diagnosis (atrial fibrillation, ischemic heart disease, or venous thromboembolism). The 1-year GIB risk was estimated using parametric time-to-event survival models and expressed as annualized risk and number needed to harm (NNH). RESULTS: Our final analysis included 311,211 patients (mean ages, 67 years for monotherapy and 69.8 years for combination antithrombotic therapy). There was no significant difference in the proportion of patients with bleeding after anticoagulant or antiplatelet monotherapy (∼3.5%/year). Combination antithrombotic therapy increased GIB risk compared with anticoagulant (NNH, 29) or antiplatelet (NNH, 31) monotherapy, regardless of the patients' diagnosis or time point analyzed. Advancing age was associated with increasing 1-year probability of GIB. Patients prescribed combination therapy were at the greatest risk for GIB, especially after the age of 75 years (GIB occurred in 10%-17.5% of patients/y). CONCLUSIONS: In an analysis of nationwide insurance and Medicare claims data, we found GIB to occur in a higher proportion of patients prescribed combinations of anticoagulant and antiplatelet agents compared with monotherapy. Among all drug exposure categories and cardiovascular conditions, the risk of GIB increased with age, especially among patients older than 75 years.

RESUMO

The management of antiplatelet and anticoagulant (ie, antithrombotic) agents is challenging in the periendoscopic setting. In this state-of-the-art update, we review current best practice recommendations focusing on the risk of immediate and delayed postpolypectomy bleeding in the context of drug discontinuation (ie, temporary interruption) and drug continuation. The data regarding polypectomy technique (cold snare vs conventional thermal-based) and prophylactic placement of hemostatic clips are evaluated to assess whether these endoscopic techniques are beneficial in reducing postpolypectomy bleeding. Finally, clinical takeaways are provided to facilitate safer polypectomy among patients on antiplatelet and anticoagulant agents.

RESUMO

Description: This update of the 2010 International Consensus Recommendations on the Management of Patients With Nonvariceal Upper Gastrointestinal Bleeding (UGIB) refines previous important statements and presents new clinically relevant recommendations. Methods: An international multidisciplinary group of experts developed the recommendations. Data sources included evidence summarized in previous recommendations, as well as systematic reviews and trials identified from a series of literature searches of several electronic bibliographic databases from inception to April 2018. Using an iterative process, group members formulated key questions. Two methodologists prepared evidence profiles and assessed quality (certainty) of evidence relevant to the key questions according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. Group members reviewed the evidence profiles and, using a consensus process, voted on recommendations and determined the strength of recommendations as strong or conditional. Recommendations: Preendoscopic management: The group suggests using a Glasgow Blatchford score of 1 or less to identify patients at very low risk for rebleeding, who may not require hospitalization. In patients without cardiovascular disease, the suggested hemoglobin threshold for blood transfusion is less than 80 g/L, with a higher threshold for those with cardiovascular disease. Endoscopic management: The group suggests that patients with acute UGIB undergo endoscopy within 24 hours of presentation. Thermocoagulation and sclerosant injection are recommended, and clips are suggested, for endoscopic therapy in patients with high-risk stigmata. Use of TC-325 (hemostatic powder) was suggested as temporizing therapy, but not as sole treatment, in patients with actively bleeding ulcers. Pharmacologic management: The group recommends that patients with bleeding ulcers with high-risk stigmata who have had successful endoscopic therapy receive high-dose proton-pump inhibitor (PPI) therapy (intravenous loading dose followed by continuous infusion) for 3 days. For these high-risk patients, continued oral PPI therapy is suggested twice daily through 14 days, then once daily for a total duration that depends on the nature of the bleeding lesion. Secondary prophylaxis: The group suggests PPI therapy for patients with previous ulcer bleeding who require antiplatelet or anticoagulant therapy for cardiovascular prophylaxis.

RESUMO

BACKGROUND & AIMS: Direct oral anticoagulant (DOAC) agents increase the risk of gastrointestinal (GI) bleeding. We investigated which DOAC had the most favorable GI safety profile and compared differences among these drugs in age-related risk of GI bleeding. METHODS: We conducted a retrospective, propensity-matched study using administrative claims data from the OptumLabs Data Warehouse of privately insured individuals and Medicare Advantage enrollees. We created 3 propensity-matched cohorts of patients with non-valvular atrial fibrillation with incident exposure to dabigatran, rivaroxaban, or apixaban from October 1, 2010 through February 28, 2015. We compared data on rivaroxaban vs dabigatran for 31,574 patients, data on apixaban vs dabigatran for 13,084 patients, and data on apixaban vs rivaroxaban for 13,130 patients. Cox proportional hazards models, stratified by age, were used to estimate rates of total GI bleeding. RESULTS: Baseline characteristics were well balanced among sub-cohorts. GI bleeding occurred more frequently in patients given rivaroxaban than dabigatran (hazard ratio [HR], 1.20; 95% confidence interval [CI], 1.00-1.45). Apixaban was associated with a lower risk of GI bleeding than dabigatran (HR, 0.39; 95% CI, 0.27-0.58; P < .001) or rivaroxaban (HR, 0.33; 95% CI, 0.22-0.49; P < .001). Rates of events for all DOACs increased among patients 75 years or older. Apixaban had a lower risk of association with GI bleeding in the very elderly than dabigatran (HR, 0.45; 95% CI, 0.29-0.71) or rivaroxaban (HR, 0.39; 95% CI, 0.25-0.61). Median times to GI bleeding were <90 days for apixaban and rivaroxaban and <120 days for dabigatran. CONCLUSIONS: In a population-based study of patients receiving DOAC agents, we found apixaban had the most favorable GI safety profile and rivaroxaban the least favorable profile. GI bleeding events among patient aged 75 years or older taking DOACs increased with age; the risk was greatest among persons 75 years. Apixaban had the most favorable GI safety profile among all age groups.

RESUMO

PURPOSE OF REVIEW: To quantify antiplatelet-related gastrointestinal bleeding (GIB), characterize patients at greatest risk and summarize risk-management strategies emphasizing evolving knowledge in acute management of antiplatelet-related bleeding. RECENT FINDINGS: New paradigms for acute management of antiplatelet-related GIB exist in the domains of resuscitation and the transfusion of blood products, strategic use of proton pump therapy and identification and eradication of Helicobacter pylori. This review will also highlight the importance of prompt resumption of cardiac aspirin and dual antiplatelet therapy following endoscopic hemostasis to minimize the risk of future cardiac events. SUMMARY: This review will provide pragmatic strategies for the management of acute antiplatelet-related GIB. Emerging areas of clinical knowledge will be addressed and knowledge gaps requiring further research to inform clinical practice will be highlighted.

RESUMO

PURPOSE OF REVIEW: To quantify direct oral anticoagulants (DOACs) related gastrointestinal bleeding (GIB), characterize patients at greatest risk and provide a pragmatic approach for the management of these drugs. This review will also summarize risk-management strategies and highlight evolving areas of clinical knowledge. RECENT FINDINGS: DOACs permit anticoagulation with predictable dosing without the need for routine serum monitoring. Since their availability on the market, they have quickly emerged as a popular alternative for patients requiring short-term and lifelong anticoagulation. However, they are associated with an increased risk of GIB when compared with warfarin; thus, gastroenterologists must be prepared to manage DOAC-related GIB and prevent drug-related complications. This review will focus on acute and elective periendoscopic DOAC management, high-risk clinical groups for DOAC-related GIB, quantification of DOAC levels, use of reversal agents and minimization of thromboembolic risk associated with temporary interruption. SUMMARY: This review will highlight pragmatic strategies for the treatment of DOAC-related bleeding and the prevention of postendoscopic DOAC bleeding. It will address new and evolving areas of periendoscopic management and identify knowledge gaps requiring further research to inform clinical practice.

RESUMO

OBJECTIVE: Abdominal obesity has been associated with increased risk of Barrett's oesophagus (BE) but the underlying mechanism is unclear. We examined the association between visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) and the risk of BE. DESIGN: A case-control study among eligible patients scheduled for elective oesophagastroduodenoscopy (EGD) and in a sample of patients eligible for screening colonoscopy recruited at the primary care clinic. All cases with definitive BE and a random sample of controls without BE were invited to undergo standardised mid-abdomen non-contrast computerised axial tomography images, which were analysed by semiautomated image segmentation software. The effect of VAT and SAT surface areas and their ratio (VAT to SAT) on BE were analysed in logistic regression models. RESULTS: A total of 173 BE cases, 343 colonoscopy controls and 172 endoscopy controls underwent study EGD and CT scan. Participants with BE were more than twice as likely to be in the highest tertile of VAT to SAT ratio (OR: 2.42 (1.51 to 3.88) and adjusted OR 1.47 (0.88 to 2.45)) than colonoscopy controls, especially for those long (≥3 cm) segment BE (3.42 (1.67 to 7.01) and adjusted OR 1.93 (0.92 to 4.09)) and for white men (adjusted OR 2.12 (1.15 to 3.90)). Adjustment for gastroesophageal reflux disease (GERD) symptoms and proton pump inhibitors (PPI) use attenuated this association, but there was a significant increase in BE risk even in the absence of GERD or PPI use. CONCLUSIONS: Large amount of visceral abdominal fat relative to subcutaneous fat is associated with a significant increase in the risk of BE. GERD may mediate some but not all of this association.

RESUMO

BACKGROUND: Complex antithrombotic therapy (CAT) prescribed to elderly patients increases the risk of gastrointestinal bleeding. We quantified upper (UGIE) and lower gastrointestinal (LGIE) events, transfusions, and hospitalizations in a national cohort of elderly veterans prescribed CAT. METHODS AND RESULTS: Veterans ≥60 years of age prescribed anticoagulant-antiplatelet, aspirin (ASA)-antiplatelet, ASA-anticoagulant, or triple therapy (ie, TRIP, anticoagulant-antiplatelet-ASA) were identified from the national pharmacy database (October 1, 2002 to September 30, 2008). Prescription-fill data were linked to Veteran Affairs and Medicare encounter files, each person-day of follow-up was assessed for CAT exposure, and outcomes were defined by using diagnostic code algorithms derived following chart abstraction. Incidence density ratios (compared with the reference category of no CAT) and survival analysis was conducted. Among 78,133 veterans (98.6% white; mean age, 72.3 [standard deviation 7.7]), 64% were prescribed ASA-antiplatelet and anticoagulant-antiplatelet and 6% were prescribed TRIP. The incidence of UGIE was 20.1/1000 patient-years, and the incidence of LGIE was 70.1/1000 patient-years. ASA-anticoagulant and TRIP were associated with the highest incidence of transfusion and hospitalization. A 40% to 60% increased risk of UGIE was observed with all strategies. LGIE was 30% higher with anticoagulant-antiplatelet, and transfusion increased with ASA-anticoagulant (hazard ratio, 6.1; 95% confidence interval, 5.2-7.1) and TRIP (hazard ratio, 5.0; 95% confidence interval, 4.2-5.8). Increased risk of hospitalization was noted with all strategies. The number needed to harm for UGIE or LGIE ranged from 52 to 65 and 15 to 23, respectively. The number needed to harm for hospitalization was 39 (anticoagulant-antiplatelet), 34 (ASA-anticoagulant), 67 (ASA-antiplatelet), and 45 (TRIP) patients. CONCLUSIONS: Among elderly patients, CAT-related LGIE and UGIE are clinically relevant risks resulting in increased hospitalizations and transfusions.

RESUMO

OBJECTIVES: The estimated association between Helicobacter pylori and Barrett's esophagus (BE) has been heterogenous across previous studies. In this study, we aimed to examine the association between H. pylori and BE and to identify factors that may explain or modify this association. METHODS: We conducted a case-control study in which we used screening colonoscopy controls recruited from primary care clinics as our primary control group in order to minimize selection bias. All participants underwent an esophagogastroduodenoscopy with gastric mapping biopsies. We used logistic regression to obtain odds ratios (ORs) and 95% confidence intervals (CIs) to estimate the association between H. pylori and BE while controlling for confounders. RESULTS: We identified 218 cases and 439 controls. The overall OR for the association between H. pylori and BE after controlling for age and white race was 0.55 (95% CI: 0.35-0.84). We observed an even stronger inverse association (OR: 0.28; 95% CI: 0.15, 0.50) among participants with corpus atrophy or antisecretory drug use ≥ 1 time per week (factors thought to lower gastric acidity), and no inverse association in patients without these factors (OR: 1.32; 95% CI: 0.66, 2.63). CONCLUSIONS: The association between H. pylori and a decreased risk for BE appears to occur in patients with factors that would likely lower gastric acidity (corpus atrophy or taking antisecretory drugs at least once a week).

RESUMO

PURPOSE OF REVIEW: Cardiac patients are a fast emerging population vulnerable to gastrointestinal bleeding (GIB) due to their use of antithrombotic medications. This review will quantify the GIB risk of cardiac patients prescribed antithrombotic medications, summarize risk-management strategies and highlight knowledge gaps. RECENT FINDINGS: As the American population ages, it is anticipated that there will be an increased incidence of upper and lower GIB related to age-specific disease, higher burden of comorbidity and increased use of anticoagulants, antiplatelets and aspirin to treat cardiac disease. New evidence has highlighted the significant and clinically relevant GIB risk. The increased use of aggressive antiplatelet and anticoagulant therapies will alter our current understanding of the epidemiology of GIB. SUMMARY: The magnitude of gastrointestinal risk in this vulnerable patient population is still relatively unexplored due to a paucity of literature. This review will highlight changing GIB trends and explore current knowledge regarding GIB risk in cardiac patients. An emphasis on a multidisciplinary approach to the care of these patients will be supported, which involves active patient participation and collaboration between cardiologists and gastroenterologists. Finally, risk-minimization strategies will be suggested and knowledge gaps will be identified.

RESUMO

Managing gastrointestinal bleeding in patients using antithrombotic agents remains challenging in clinical practice. This review article provides a comprehensive and evidence-based approach to managing acute antithrombotic-related gastrointestinal bleeding, focusing on the triage of patients, appropriate resuscitation, and timely endoscopy. The latest clinical practice guidelines are highlighted to guide decisions concerning the use of reversal agents, temporary interruption, and resumption of antithrombotic drugs. Additionally, preventive measures are discussed to lower the risk of future bleeding and minimize complications among patients prescribed antithrombotic drugs.

RESUMO

BACKGROUND & AIMS: Effectiveness of early treatment with biologics and immunomodulator therapy on healthcare utilization remains poorly defined. We assessed rates of hospitalization and surgery within 1 year after initiation of infliximab and/or immunomodulator therapy in a United States cohort of patients with inflammatory bowel disease. METHODS: We conducted a retrospective, observational cohort study of veterans with Crohn's disease or ulcerative colitis by using administrative data from 176 Department of Veteran Affairs facilities (October 1, 2001 through September 30, 2009). Inpatient, outpatient, and death records were linked longitudinally with prescription fill data. Each person-day of follow-up was assessed for treatment with infliximab, immunomodulators, both (dual therapy), or neither. We calculated drug exposure time and used Poisson and logistic regression analyses to assess outcomes. RESULTS: The cohort of 20,474 patients included 8042 patients with Crohn's disease and 12,432 with ulcerative colitis (93.9% male; 72.5% white; mean age, 60.9 ± 14.5 years) prescribed infliximab (0.17%), immunomodulator (1.3%), or dual therapy (1.5%). Adjusted models revealed 50% relative reductions in hospitalization among patients who received 9.2 months of immunomodulator monotherapy, 8 months of infliximab, or 7.7 months of dual therapy. A 50% relative reduction in surgery was observed among patients receiving 7 months of infliximab or 5 months of dual therapy. Analysis of dose-response data revealed 73.1% and 92% reductions in risk of hospitalization and surgery, respectively, after 9 months of dual therapy. CONCLUSIONS: On the basis of a retrospective cohort study, dual therapy with infliximab and an immunomodulator for <8 months is associated with significant reductions in hospitalization and surgery within 1 year of the start of therapy. These findings indicate that patients with IBD are more likely to benefit if dual therapy is initiated earlier in their first year of therapy.

RESUMO

BACKGROUND & AIMS: Abdominal obesity increases the risk of gastroesophageal reflux disease (GERD) and also might contribute to the development of Barrett's esophagus (BE), although results are inconsistent. We examined the effects of waist-to-hip ratio (WHR) and body mass index (BMI) on the risk of BE and investigated whether race, GERD symptoms, or hiatus hernia were involved. METHODS: We conducted a case-control study using data from eligible patients who underwent elective esophagogastroduodenoscopy; 237 patients had BE and the other 1021 patients served as endoscopy controls. We also analyzed data and tissue samples from enrolled patients who were eligible for screening colonoscopies at a primary care clinic (colonoscopy controls, n = 479). All patients underwent esophagogastroduodenoscopy, completed a survey, and had anthropometric measurements taken. WHR was categorized as high if it was 0.9 or greater for men or 0.85 or greater for women. Data were analyzed with logistic regression. RESULTS: There was no association between BMI and BE. However, more patients with BE had a high WHR (92.4%) than endoscopy controls (79.5%) or colonoscopy controls (84.6%) (P < .001 and P = .008, respectively). In adjusted analysis, patients with BE were 2-fold more likely to have a high WHR than endoscopy controls (odds ratio [OR], 1.93; 95% confidence interval [CI], 1.1-3.5), this association was stronger for patients with long-segment BE (OR, 2.81; 95% CI, 1.0-7.9). A high WHR was associated significantly with BE only in whites (OR, 2.5; 95% CI, 1.2-5.4), but not in blacks or Hispanics. GERD symptoms, hiatus hernia, or gastroesophageal valve flap grade could not account for the association. CONCLUSIONS: High WHR, but not BMI, is associated with a significant increase in the risk of BE, especially long-segment BE and in whites. The association is not caused by GERD symptoms or hiatus hernia.

RESUMO

PURPOSE OF REVIEW: To quantify the novel oral anticoagulant (NOAC)-related gastrointestinal bleeding, summarize the management strategies and highlight the knowledge gaps. RECENT FINDINGS: Dabigatran, rivaroxaban and apixaban differ from warfarin with their fixed oral dose and no requirement for routine monitoring. Patients at highest risk of thromboembolism benefit most from NOACs; however, there is a clinically significant risk for NOAC-related gastrointestinal bleeding. The management of NOACs in the acute and elective setting differs from that used with warfarin. SUMMARY: The magnitude of gastrointestinal risk is still unclear because of paucity of literature. Current risk-stratification models are incomplete and cannot be used solely to predict future risk. The periendoscopic management requires an understanding of drug half-life, metabolism and patient's ability to excrete the agent. Acute bleeding management relies on fluid resuscitation to promote renal excretion of active metabolite, withholding the doses and timely management of endoscopic stigmata. The administration of coagulation factors (fresh frozen plasma, prothrombin complex concentrates or recombinant activated FVII) is more successful in reversing the activity of the upstream inhibitors of coagulation (rivaroxaban and apixaban) than dabigatran which is a direct thrombin inhibitor.
