Cheung KS, Li B, Wong IYH, Law S, Leung WK. Benefit and Harm of Aspirin on Mortality From Gastrointestinal Cancers Vs Bleeding in Helicobacter pylori-Eradicated Patients. Clin Gastroenterol Hepatol 2024:S1542-3565(24)00442-7. [PMID: 38750871 DOI: 10.1016/j.cgh.2024.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2023] [Revised: 05/02/2024] [Accepted: 05/03/2024] [Indexed: 06/10/2024]
Abstract
BACKGROUND & AIMS We investigated the benefit-risk profile of aspirin on mortality reduction from chemoprevention of gastrointestinal (GI) cancer vs excess mortality from bleeding among Helicobacter pylori-eradicated patients, and its interaction with proton pump inhibitors (PPIs). METHODS H pylori-eradicated patients (between 2003 and 2016), identified from a territory-wide database, were observed from the date of H pylori therapy until death or the end of the study (July 2020). Primary exposure was aspirin use as time-varying variable. The primary outcome was GI cancer-related (gastrointestinal, hepatobiliary, or pancreatic cancer) death and the secondary outcome was bleeding-related (gastrointestinal bleeding or intracranial bleeding) death. The adjusted hazard ratio (aHR) of outcomes was calculated by multivariable Cox model after adjusting for age, sex, comorbidities, and concomitant medications. The benefit-risk profile was expressed as the adjusted absolute risk difference of cancer-related deaths and bleeding-related deaths between aspirin users and nonusers. RESULTS A total of 87,967 subjects were followed up for a median of 10.1 years, with 1294 (1.5%) GI cancer-related deaths and 304 (0.3%) bleeding-related deaths. Aspirin was associated with lower GI cancer-related mortality (aHR, 0.51; 95% CI, 0.42-0.61), but higher bleeding-related mortality (aHR, 1.52; 95% CI, 1.11-2.08). Among PPI users, the aHR of bleeding-related mortality with aspirin was 1.06 (95% CI, 0.70-1.63). For the whole cohort, the adjusted absolute risk difference between aspirin users and nonusers was 7 (95% CI, 5-8) fewer cancer-related and 1 (95% CI, 0.3-3) more bleeding-related death per 10,000 person-years. Among concomitant PPI-aspirin use, there were 9 (95% CI, 8-10) fewer cancer-related deaths per 10,000 person-years without an increase in bleeding-related deaths. CONCLUSIONS GI cancer mortality benefit from aspirin outweighs bleeding-related mortality in H pylori-eradicated subjects, which is enhanced further by PPI use.

Abstract
Helicobacter pylori is the main etiopathogenetic factor of chronic gastritis, peptic ulcer disease and gastric cancer. The world's population is shifting towards older people, who have the highest prevalence of H. pylori. Aging-related peculiarities could have an impact on the treatment of H. pylori and there is still a lack of research data in the older population. The aim of this review was to summarize the findings of the most recent information, publications and studies on the issues relating to H. pylori infection in older patients. H. pylori eradication offers gastrointestinal and extra gastrointestinal benefits in older patients. Based on the main guidelines, H. pylori should be eradicated independent of the patient's age, only reconsidering cases with terminal illness and low life expectancy. Proton pump inhibitors are generally safe and well tolerated. Some antibiotics require dose adjustment only in advanced renal insufficiency and the risk of hepatotoxicity is very low. Special precautions should be taken in patients with polypharmacy and those taking aspirin or non-steroidal anti-inflammatory drugs. In older patients, H. pylori eradication treatment frequently causes only mild and short-term adverse events; however, treatment compliance is usually still very good. H. pylori treatment in older patients does not increase the risk of Clostridium difficile infection. Optimal eradication effectiveness (> 90%) is mostly achieved with bismuth- and non-bismuth-based quadruple therapies. Susceptibility-guided treatment of H. pylori can contribute to increasing the effectiveness of eradication regimens in older adults. To achieve optimal H. pylori eradication effectiveness in older patients, the same guidelines, which are applied to adults, also apply to this population: avoiding repetitive treatment prescriptions, choosing quadruple therapies, prescribing longer treatment duration and administering high-dose proton pump inhibitors twice daily.

[PMID: 37771340 PMCID: PMC10523195 DOI: 10.4330/wjc.v15.i8.375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 06/23/2023] [Accepted: 08/08/2023] [Indexed: 08/21/2023] Open
Abstract
Aspirin, other antiplatelet agents, and anticoagulant drugs are used across a wide spectrum of cardiovascular and cerebrovascular diseases. A concomitant proton pump inhibitor (PPI) treatment is often prescribed in these patients, as gastrointestinal complications are relatively frequent. On the other hand, a potential increased risk of cardiovascular events has been suggested in patients treated with PPIs; in particular, it has been discussed whether these drugs may reduce the cardiovascular protection of clopidogrel, due to pharmacodynamic and pharmacokinetic interactions through hepatic metabolism. Previously, the concomitant use of clopidogrel and omeprazole or esomeprazole has been discouraged. In contrast, it remains less known whether PPI use may affect the clinical efficacy of ticagrelor and prasugrel, new P2Y12 receptor antagonists. Current guidelines recommend PPI use in combination with antiplatelet treatment in patients with risk factors for gastrointestinal bleeding, including advanced age, concurrent use of anticoagulants, steroids, or non-steroidal anti-inflammatory drugs, and Helicobacter pylori (H. pylori) infection. In patients taking oral anticoagulant with risk factors for gastrointestinal bleeding, PPIs could be recommended, even if their usefulness deserves further data. H. pylori infection should always be investigated and treated in patients with a history of peptic ulcer disease (with or without complication) treated with antithrombotic drugs. The present review summarizes the current knowledge regarding the widespread combined use of platelet inhibitors, anticoagulants, and PPIs, discussing consequent clinical implications.

Abstract
Helicobacter pylori (H. pylori) infection is prevalent and has a rapidly increasing antibiotic resistance rate in Vietnam. Reinfection is quite common, and gastric carcinoma remains one of the most common malignancies, which is not uncommon to develop after successful eradication. The purpose of this consensus is to provide updated recommendations on the management of H. pylori infection in the country. The consensus panel consisted of 32 experts from 14 major universities and institutions in Vietnam who were invited to review the evidence and develop the statements using the Delphi method. The process followed the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The consensus level was defined as ≥80% for agreement on the proposed statements. Due to the limited availability of high-quality local evidence, this consensus was also based on high-quality evidence from international studies, especially those conducted in other populations in the Asia-Pacific region. The panel finally reached a consensus on 27 statements after two voting rounds, which consisted of four sections (1) indications for testing and selection of diagnostic tests (2), treatment regimens, (3) post-treatment confirmation of H. pylori status, and (4) reinfection prevention methods and follow-up after eradication. Important issues that require further evidence include studies on third-line regimens, strategies to prevent H. pylori reinfection, and post-eradication follow-up for precancerous gastric lesions. We hope this consensus will help guide the current clinical practice in Vietnam and promote multicenter studies in the country and international collaborations.

Abstract
BACKGROUND Peptic ulcers in patients receiving aspirin are associated with Helicobacter pylori infection. We aimed to investigate whether H pylori eradication would protect against aspirin-associated ulcer bleeding. METHODS We conducted a randomised, double-blind, placebo-controlled trial (Helicobacter Eradication Aspirin Trial [HEAT]) at 1208 primary care centres in the UK, using routinely collected clinical data. Eligible patients were aged 60 years or older who were receiving aspirin at a daily dose of 325 mg or less (with four or more 28-day prescriptions in the past year) and had a positive C13 urea breath test for H pylori at screening. Patients receiving ulcerogenic or gastroprotective medication were excluded. Participants were randomly assigned (1:1) to receive either a combination of oral clarithromycin 500 mg, metronidazole 400 mg, and lansoprazole 30 mg (active eradication), or oral placebo (control), twice daily for 1 week. Participants, their general practitioners and health-care providers, and the research nurses, trial team, adjudication committee, and analysis team were all masked to group allocation throughout the trial. Follow-up was by scrutiny of electronic data in primary and secondary care. The primary outcome was time to hospitalisation or death due to definite or probable peptic ulcer bleeding, and was analysed by Cox proportional hazards methods in the intention-to-treat population. This trial is registered with EudraCT, 2011-003425-96. FINDINGS Between Sept 14, 2012, and Nov 22, 2017, 30 166 patients had breath testing for H pylori, 5367 had a positive result, and 5352 were randomly assigned to receive active eradication (n=2677) or placebo (n=2675) and were followed up for a median of 5·0 years (IQR 3·9-6·4). Analysis of the primary outcome showed a significant departure from proportional hazards assumptions (p=0·0068), requiring analysis over separate time periods. There was a significant reduction in incidence of the primary outcome in the active eradication group in the first 2·5 years of follow-up compared with the control group (six episodes adjudicated as definite or probable peptic ulcer bleeds, rate 0·92 [95% CI 0·41-2·04] per 1000 person-years vs 17 episodes, rate 2·61 [1·62-4·19] per 1000 person-years; hazard ratio [HR] 0·35 [95% CI 0·14-0·89]; p=0·028). This advantage remained significant after adjusting for the competing risk of death (p=0·028) but was lost with longer follow-up (HR 1·31 [95% CI 0·55-3·11] in the period after the first 2·5 years; p=0·54). Reports of adverse events were actively solicited; taste disturbance was the most common event (787 patients). INTERPRETATION H pylori eradication protects against aspirin-associated peptic ulcer bleeding, but this might not be sustained in the long term.

Abstract
The study is aimed at evaluating the application value of ultrasound combined with gastroscopy in diagnosing gastrointestinal bleeding (GIB) caused by Helicobacter pylori (HP). An ultrasound combined with a gastroscopy diagnostic model based on improved K-means Singular Value Decomposition (N-KSVD) was proposed first. 86 patients with Peptic ulcer (PU) and GIB admitted to our Hospital were selected and defined as the test group, and 86 PU patients free of GIB during the same period were selected as the control group. The two groups were observed for clinical manifestations and HP detection results. The results showed that when the noise ρ was 10, 30, 50, and 70, the Peak Signal to Noise Ratio (PSNR) values of N-KSVD dictionary after denoising were 35.55, 30.47, 27.91, and 26.08, respectively, and the structure similarity index measure (SSIM) values were 0.91, 0.827, 0.763, and 0.709, respectively. Those were greater than those of DCT dictionary and Global dictionary and showed statistically significant differences versus the DCT dictionary (P < 0.05). In the test group, there were 60 HP-positives and 26 HP-negatives, and there was significant difference in the numbers of HP-positives and HP-negatives (P < 0.05), but no significant difference in gender and age (P > 0.05). Of the subjects with abdominal pain, HP-positives accounted for 59.02% and HP-negatives accounted for 37.67%, showing significant differences (P < 0.05). Finally, the size of the ulcer lesion in HP-positives and HP-negatives was compared. It was found that 71.57% of HP-positives had ulcers with a diameter of 0-1 cm, and 28.43% had ulcers with a diameter of ≥1 cm. Compared with HP-negatives, the difference was statistically significant (P < 0.05). In conclusion, N-KSVD-based ultrasound combined with gastroscopy demonstrated good denoising effects and was effective in the diagnosis of GIB caused by HP.

Abstract
The incidence of cardiovascular diseases has increased due to the aging of the population. Therefore, antithrombotic therapy is increasingly prescribed for cardiovascular prevention. However, long-term use of antithrombotic drugs can cause damage to the digestive tract. Gastrointestinal complications, including ulcer and bleeding, are relatively common during antithrombotic therapy. In order to minimize the digestive tract damage induced by antithrombotic drugs, there are several strategies available, including reducing modifiable risk factors, using the most optimal antithrombotic regimen to ensure gastrointestinal risk-cardiovascular benefit balance, and using gastroprotective agents. In recent years, researchers are attempting to find new solutions from traditional Chinese medicine. Studies have shown that traditional Chinese medicine has its own characteristics and clinical advantages in preventing and treating diseases. In this review, we provide a summary of recent updates regarding gastrointestinal damage induced by antithrombotic therapy as well as its prevention and treatment with both traditional Chinese and Western medicine.

Abstract
Aspirin and P2Y12 receptor antagonists are widely used across the spectrum of cardiovascular and cerebrovascular diseases. Gastrointestinal complications, including ulcer and bleeding, are relatively common during antiplatelet treatment and, therefore, concomitant proton pump inhibitor (PPI) treatment is often prescribed. However, potential increased risk of cardiovascular events has been suggested for PPIs, and, in recent years, it has been discussed whether these drugs may reduce the cardiovascular protection by aspirin and, even more so, clopidogrel. Indeed, pharmacodynamic and pharmacokinetic studies suggested an interaction through hepatic CYP2C19 between PPIs and clopidogrel, which could translate into clinical inefficacy, leading to higher rates of cardiovascular events. The FDA and the EMA sent a warning in 2010 discouraging the concomitant use of clopidogrel with omeprazole or esomeprazole. In addition, whether the use of PPIs may affect the clinical efficacy of the new P2Y12 receptor antagonists, ticagrelor and prasugrel, remains less known. According to current guidelines, PPIs in combination with antiplatelet treatment are recommended in patients with risk factors for gastrointestinal bleeding, including advanced age, concurrent use of anticoagulants, steroids or non-steroidal anti-inflammatory drugs, and Helicobacter pylori infection. Like vitamin K antagonists (VKAs), DOACs can determine gastrointestinal bleeding. Results from both randomized clinical trials and observational studies suggest that high-dose dabigatran (150 mg bid), rivaroxaban and high-dose edoxaban (60 mg daily) are associated with a higher risk of GI bleeding as compared with apixaban and warfarin. In patients taking oral anticoagulant with GI risk factor, PPI could be recommended, even if usefulness of PPIs in these patients deserves further data. Helicobacter pylori should always be searched, and treated, in patients with history of peptic ulcer disease (with or without complication). Given the large number of patients treated with antithrombotic drugs and PPIs, even a minor reduction of platelet inhibition or anticoagulant effect potentially carries a considerable clinical impact. The present joint statement by ANMCO and AIGO summarizes the current knowledge regarding the widespread use of platelet inhibitors, anticoagulants, and PPIs in combination. Moreover, it outlines evidence supporting or opposing drug interactions between these drugs and discusses consequent clinical implications.

Abstract
Purpose of review Peptic ulcer disease (PUD) is a recognized complication of non-steroidal anti-inflammatory drugs (NSAIDs). Stress ulcers are a concern for intensive care unit (ICU) patients; PUD is also an issue for patients taking anticoagulation. Helicobacter pylori test and treat is an option for patients starting NSAID therapy, and proton pump inhibitors (PPIs) may reduce PUD in NSAID patients and other high-risk groups. Recent findings There are a large number of trials that demonstrate that Helicobacter pylori eradication reduces PUD in NSAID patients. PPI is also effective at reducing PUD in this group and is also effective in ICU patients and those on anticoagulants. The effect is too modest for PPI to be recommended in everyone, and more research is needed as to which groups would benefit the most. Increasing age, past history of PUD, and comorbidity are the most important risk factors. Summary H. pylori test and treat should be offered to older patients starting NSAIDS, while PPIs should be prescribed to patients that are at high risk of developing PUD and at risk of dying from PUD complications.

Abstract
Nanocomposite-based drug delivery systems with intrinsic controlled release properties are of great interest in biomedical applications. We report a novel polylactic acid (PLA)/halloysite nanotube (HNT) nanocomposite-based drug delivery system. PLA/HNT nanocomposites have shown immense potential for use in biomedical applications due to their favorable cyto- and hemo-compatibility. The objective of this study was to evaluate the release of active pharmaceutical ingredients (API) from PLA/HNT composites matrix and the effect of preloading the API into the lumen of the HNT on its release profile. Aspirin was used in this study as a model drug as it is a common nonsteroidal anti-inflammatory and antiplatelet agent widely used for various medical conditions. These two types of drug-loaded PLA/HNT nanocomposites were characterised by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), surface wettability and mechanical testing. Statistical analysis was conducted on numerical data. Drug entrapment and in vitro drug release studies were conducted using UV spectrophotometry. Results indicate that aspirin was successfully loaded into the lumen of HNT, which resulted in the sustained release of aspirin from the nanocomposites. Furthermore, the addition of HNT into the polymer matrix increased the mechanical properties, indicating its suitability as a drug-eluting reinforcing agent.

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.
