Abstract
Helicobacter pylori is the most common cause of gastroduodenal diseases. The concept that cagA-positive H. pylori is a risk factor for gastric cancer appears to be true only for H. pylori strains from Western countries. Other virulent genes may have a synergistic interaction with cagA during pathogenesis. This study aims to investigate H. pylori cagA, vacA, and iceA prevalence, genotypes, and their association to clinical outcomes in Vietnamese patients. The cagA status and vacA and iceA genotypes were determined using the PCR technique on DNA extracted from gastric biopsies of 141 patients with gastroduodenal diseases. After performing molecular analysis for cagA, vacA, and iceA genes, samples with mixed H. pylori strains, positivity, or negativity for both cagA and cagPAI-empty site, or unidentified genotypes were excluded. Finally, 107 samples were examined. The presence of the cagA, vacA, and iceA genes were detected in 77.6%, 100%, and 80.4% of cases, respectively. Notably, cagA( +) with EPIYA-ABD, vacA s1i1m1, vacA s1i1m2, iceA1, and iceA2 accounted for 73.8%, 44.9%, 33.6%, 48.6%, and 31.8% of cases, respectively. Four iceA2 subtypes (24-aa, 59-aa, 94-aa, and 129-aa variants) were found, with the 59-aa variant the most prevalent (70.6%). The cagA( +)/vacAs1i1m1/iceA1 and cagA( +)/vacAs1i1m2/iceA1 combinations were found in 26.2% and 25.1% of cases, respectively. A multivariable logistic regression analysis was performed, after adjusting for age and gender, with the gastritis group was used as a reference control. Statistically significant associations were found between the vacA s1i1m2 genotype, the iceA1 variant, and the cagA( +)/vacAs1i1m2/iceA1 combination and gastric cancer; the adjusted ORs were estimated as 18.02 (95% CI: 3.39-95.81), 4.09 (95% CI: 1.1-15.08), and 16.19 (95% CI: 3.42-76.66), respectively. Interestingly, for the first time, our study found that vacA s1i1m2, but not vacA s1i1m1, was a risk factor for gastric cancer. This study illustrates the genetic diversity of the H. pylori cagA, vacA, and iceA genes across geographical regions and contributes to understanding the importance of these genotypes for clinical outcomes.

Abstract
PURPOSE The aim of the study was to test the established hypothesis that biopsies of spontaneous gastric perforations should be taken to rule out cancer. METHODS A prospective observational study was performed. Consecutive patients with spontaneous gastric perforation were included. Biopsies of the edges of the perforation were submitted for histological evaluation. The epithelial type as well as the nature of the pathology were evaluated. RESULTS Sixty-eight patients were included. Eight (12%) biopsies revealed duodenal origin. Sixty (88%) biopsies revealed gastric mucosa of which 33 (48%) could be specifically typed. All biopsies revealed benign ulceration. No malignancies were detected in these biopsies or on subsequent gastroscopic follow up. CONCLUSION This study suggests that routine intraoperative biopsy of gastric perforation may be questioned. Biopsy is probably better performed endoscopically after recovery.

Abstract
BACKGROUND Second-look endoscopy (SLE) to prevent recurrent bleeding in patients with peptic ulcer disease (PUD) and those undergoing endoscopic submucosal dissection (ESD) is routinely being performed. Conflicting evidence exists regarding efficacy, risk, benefit, and cost-effectiveness. AIM To identify the role and effectiveness of SLE in ESD and PUD, associated rebleeding and PUD-related outcomes like mortality, hospital length of stay, need for endoscopic or surgical intervention and blood transfusions. METHODS A systematic review of literature databases PubMed, Cochrane, and Embase was conducted from inception to January 5, 2023. Randomized controlled trials that compared patients with SLE to those who did not have SLE or evaluated the role of prophylactic hemostasis during SLE compared to other conservative interventions were included. The study was conducted per PRISMA guidelines, and the protocol was registered in PROSPERO (ID CRD42023427555:). RevMan was used to perform meta-analysis, and Mantel-Haenszel Odds ratio (OR) were generated using random effect models. RESULTS A total of twelve studies with 2687 patients were included in our systematic review and meta-analysis, of which 1074 patients underwent SLE after ESD and 1613 patients underwent SLE after PUD-related bleeding. In ESD, the rates of rebleeding were 7% in the SLE group compared to 4.4% in the non-SLE group with OR 1.65, 95% confidence intervals (CI) of 0.96 to 2.85; P = 0.07, whereas it was 11% in the SLE group compared to 13% in the non-SLE group with OR 0.8 95%CI: 0.50 to 1.29; P = 0.36. The mean difference in the blood transfusion rates in the SLE and no SLE group in PUD was OR 0.01, 95%CI: -0.22 to 0.25; P = 0.91. In SLE vs non-SLE groups with PUD, the OR for Endoscopic intervention was 0.29, 95%CI: 0.08 to 1.00; P = 0.05 while it was OR 2.03, 95%CI: 0.95 to 4.33; P = 0.07, for surgical intervention. The mean difference in the hospital length of stay was -3.57 d between the SLE and no SLE groups in PUD with 95%CI: -7.84 to 0.69; P = 0.10, denoting an average of approximately 3 fewer days of hospital stay among patients with PUD who underwent SLE. For mortality between SLE and non-SLE groups in PUD, the OR was 0.88, 95%CI: 0.45 to 1.72; P = 0.70. CONCLUSION SLE does not confer any benefit in preventing ESD and PUD-associated rebleeding. SLE also does not provide any significant improvement in mortality, need for interventions, or blood transfusions in PUD patients. SLE decreases the hospital length of stay on average by 3.5 d in PUD patients.

Abstract
A comprehensive overview of the associations between air pollution and the risk of gastrointestinal (GI) diseases has been lacking. We aimed to examine the relationships of long-term exposure to ambient particulate matter (PM) with aerodynamic diameter ≤2.5 μm (PM2.5), 2.5-10 μm (PMcoarse), ≤10 μm (PM10), nitrogen dioxide (NO2), and nitrogen oxides (NOx), with the risk of incident GI diseases, and to explore the interplay between air pollution and genetic susceptibility. A total of 465,703 participants free of GI diseases in the UK Biobank were included at baseline. Land use regression models were employed to calculate the residential air pollutants concentrations. Cox proportional hazard models were used to evaluate the associations of air pollutants with the risk of GI diseases. The dose-response relationships of air pollutants with the risk of GI diseases were evaluated by restricted cubic spline curves. We found that long-term exposure to ambient air pollutants was positively associated with the risk of peptic ulcer (PM2.5 : Q4 vs. Q1: hazard ratio (HR) 1.272, 95% confidence interval (CI) 1.179-1.372, NO2: 1.220, 1.131-1.316, and NOx: 1.277, 1.184-1.376) and chronic gastritis (PM2.5: 1.454, 1.309-1.616, PM10 : 1.232, 1.112-1.366, NO2: 1.456, 1.311-1.617, and NOx: 1.419, 1.280-1.574) after Bonferroni correction. Participants with high genetic risk and high air pollution exposure had the highest risk of peptic ulcer, compared to those with low genetic risk and low air pollution exposure (PM2.5: HR 1.558, 95%CI 1.384-1.754, NO2: 1.762, 1.395-2.227, and NOx: 1.575, 1.403-1.769). However, no significant additive or multiplicative interaction between air pollution and genetic risk was found. In conclusion, long-term exposure to ambient air pollutants was associated with increased risk of peptic ulcer and chronic gastritis.

Abstract
INTRODUCTION There are uncertainties surrounding the spectrum of upper gastrointestinal (UGI) diseases in sub-Saharan Africa. This is mainly due to the limitations of data collection and recording. We previously reported an audit of UGI endoscopic diagnoses in Zambia spanning from 1977 to 2014. We now have extended this analysis to include subsequent years, in order to provide a more comprehensive picture of how the diagnoses have evolved over 4 decades. METHODS We combined data collected from the endoscopy unit at the University Teaching Hospital (UTH) in Lusaka during a previous review with that collected from the beginning of 2015 to the end of 2021. Since 2015, an electronic data base of endoscopy reports at the UTH was kept. The electronic data base was composed of drop-down menus that allowed for standardised reporting of findings. Collected data were coded by two experienced endoscopists and analysed. RESULTS In total, the analysis included 25,849 endoscopic records covering 43 years. The number of endoscopic procedures performed per year increased drastically in 2010. With the exception of the last 2 years, the proportion of normal endoscopies also increased during the time under review. In total, the number of gastric cancer (GC) cases was 658 (3%) while that of oesophageal cancer (OC) was 1168 (5%). The number of GC and OC diagnoses increased significantly over the period under review, (p < 0.001 for both). For OC the increase remained significant when analysed as a percentage of all procedures performed (p < 0.001). Gastric ulcers (GU) were diagnosed in 2095 (8%) cases, duodenal ulcers (DU) in 2276 (9%) cases and 239 (1%) had both ulcer types. DU diagnosis showed a significantly decreasing trend over each decade (p < 0.001) while GU followed an increasing trend (p < 0.001). CONCLUSIONS UGI endoscopic findings in Lusaka, Zambia, have evolved over the past four decades with a significant increase of OC and GU diagnoses. Reasons for these observations are yet to be established.

Abstract
Upper gastrointestinal bleeding (UGIB) continues to be an important cause for emergency room visits and carries significant morbidity and mortality. Early resuscitative measures form the basis of the management of patients presenting with UGIB and can improve the outcomes of such patients including lowering mortality. In this review, using an evidence-based approach, we discuss the initial assessment and resuscitation of patients presenting with UGIB including identifying clues from history and physical examination to confirm UGIB, preendoscopic risk assessment tools, the role of early fluid resuscitation, utilization of blood products, use of pharmacologic interventions, and the optimal timing of endoscopy.

Abstract
BACKGROUND Low-dose aspirin (LDA) administration is associated with an elevated risk of recurring peptic ulcer (PU) and gastrointestinal (GI) hemorrhage. AIMS This systematic review and Bayesian network meta-analysis aimed to comprehensively assess the effectiveness of diverse medications in preventing the recurrence of PU and GI hemorrhage in patients with a history of PU receiving long-term LDA therapy. METHODS This systematic review and network meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and was registered on PROSPERO (CRD42023406550). We searched relevant studies in main databases from inception to March 2023. All statistical analyses were performed using R (version 4.1.3), with the "Gemtc" (version 1.0-1) package. The pooled risk ratio (RR), corresponding 95% credible interval (95% CrI), and the surface under the cumulative ranking curve (SUCRA) were calculated. RESULTS 11 Randomized clinical trials (RCTs) were included. The analysis underscored pantoprazole was the most efficacious for reducing the risk of PU recurrence (RR [95% CrI] = 0.02 [0, 0.28]; SUCRA: 90.76%), followed by vonoprazan (RR [95% CrI] = 0.03 [0, 0.19]; SUCRA: 86.47%), comparing with the placebo group. Pantoprazole also performed well in preventing GI hemorrhage (RR [95% CrI] = 0.01[0, 0.42]; SUCRA: 87.12%) compared with Teprenone. CONCLUSIONS For patients with a history of PU receiving LDA, pantoprazole and vonoprazan might be the optimal choices to prevent PU recurrence and GI hemorrhage.

Abstract
BACKGROUND The detection rate of peptic ulcer in children is improving, with development of diagnostic procedures. Gastroscopy is the gold standard for the diagnosis of peptic ulcer, but it is an invasive procedure. Gastrointestinal contrast-enhanced ultrasonography (CEUS) has the advantages of being painless, noninvasive, nonradioactive, easy to use, and safe. AIM To investigate the clinical value of CEUS for diagnosis and treatment of peptic ulcer in children. METHODS We investigated 43 children with digestive tract symptoms in our hospital from January 2021 to June 2022. All children were examined by routine ultrasound, gastrointestinal CEUS, and gastroscopy. The pathological results of gastroscopy were taken as the gold standard. Routine ultrasonography was performed before gastrointestinal CEUS. Conventional ultrasound showed the thickness of the gastroduodenal wall, gastric peristalsis, and the adjacent organs and tissues around the abdominal cavity. Gastrointestinal CEUS recorded the thickness of the gastroduodenal wall; the size, location and shape of the ulcer; gastric peristalsis; and adjacent organs and tissues around the abdominal cavity. The results of routine ultrasound and gastrointestinal ultrasound were compared with those of gastroscopy to evaluate the diagnostic results and coincidence rate of routine ultrasound and gastrointestinal CEUS. All children received informed consent from their guardians for CEUS. This study was reviewed and approved by the hospital medical ethics committee. RESULTS Among the 43 children, 17 (15 male, 2 female) were diagnosed with peptic ulcer by gastroscopy. There were 26 children with nonpeptic ulcer. There were eight cases of peptic ulcer and 35 of nonpeptic ulcer diagnosed by conventional ultrasound. The diagnostic coincidence rate of peptic ulcer in children diagnosed by conventional ultrasound was 79.1% (34/43), which was significantly different from that of gastroscopy (P = 0.033). It indicates that the coincidence rate of gastrointestinal contrast-enhanced ultrasound and gastroscope is low. Fifteen cases of peptic ulcer and 28 of nonpeptic ulcer were diagnosed by CEUS. The diagnostic coincidence rate of peptic ulcer in children was 95.3% (41/43). There was no significant difference between CEUS and gastroscopy (P = 0.655). It indicates that the coincidence rate of gastrointestinal contrast-enhanced ultrasound and gastroscope is high. CONCLUSION Gastrointestinal CEUS has a high coincidence rate in the diagnosis of peptic ulcer in children, and can be used as a preliminary examination method.

Abstract
First-line drugs for peptic ulcer (PU) treatment are typically limited by poor targeting and adverse effects associated with long-term use. Despite recent advancements in novel therapeutic approaches for PU, the development of sustained-release delivery systems tailored to specific pathological characteristics remains challenging. Persistent inflammation, particularly gastric inflammatory microenvironment imbalance, characterizes the PU. In this study, we prepared an in situ gel composed of sodium alginate, deacetylated gellan gum, calcium citrate, and Bletilla striata polysaccharide (BSP) to achieve sustained release of BSP. The BSP in situ gel demonstrated favorable fluidity in vitro and completed self-assembly in vivo in response to the acidic milieu at a pH of 1.5. Furthermore, the shear, extrusion, and deformation properties increased by 26.4 %, 103.7 %, and 46.3 %, respectively, with long-term gastric retention (4 h) and mucosal adaptation. Animal experiments confirmed that the BSP in situ gel could attenuate necrotic injury and inflammatory cell infiltration, maintain mucosal barrier integrity, regulate cytokine imbalance and inflammation-associated hyperapoptosis, thus effectively alleviate the inflammatory microenvironmental imbalance in PU without significant side effects. Overall, our findings demonstrated that the BSP in situ gel is a promising therapeutic strategy for PU and opens avenues for developing self-assembled formulations targeting the pathological features of PUs.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) colonizes human gastric mucosa and is classified as class one carcinogenic bacteria. In this regard, this study aimed to detect major virulence factors in H. pylori strains recovered from gastric biopsy in patients referred to Aras Clinique in Ardabil, northwest of Iran (2019-2021). MATERIALS AND METHODS In this descriptive-cross sectional study, 287 dyspeptic patients were included. For bacterial isolation, gastric biopsy specimens (n=287) were taken from gastric antrum, then aseptically were cultured on the selective medium and incubated at 37C in microaerophilic conditions for 3-5 days. RESULTS 25.18% of all (n = 70) patients were found to be infected with H. pylori upon endoscopy. Of them, 9 patients (12.857%) and 2 patients (2.875%) had peptic ulcer disease and gastric cancer respectively. According to the different patterns of virulence factors, 57 virutypes were identified in which oipA-vacAs1-vacAm2 (3, 4.28% n =) and oipA-vacAs1-vacAs2-vacAm2 (3, 4.28% n =) were the most common patterns. The simultaneous presence of vacAS2, vacAm2 and hopQ2 genes was observed in both patients with gastric cancer. OipA (n = 562.5%), VacAs1 (n = 6.75%), VacAs2 (n = 6.75%), and VacAm2 (n = 787.5%) were found to be the most prevalent virulence factor. CONCLUSION According previous studies, it is confirmed that the cagPAI gene cluster and vacA gene alleles are strongly correlated with gastritis and gastrointestinal tract adenocarcinomas. Our study indicated that 50% of the indigenous strains of H. pylori harbor these oncogenic genes and they are hypervirulent.

Abstract
BACKGROUND/AIMS Acute peptic ulcer bleeding is the most common cause of non-variceal upper gastrointestinal bleeding (NVUGIB). Endoscopic hemostasis is the standard treatment. However, various conditions complicate endoscopic hemostasis. Transarterial visceral embolization (TAE) may be helpful as a rescue therapy. This study aimed to investigate the factors associated with rebleeding after TAE. METHODS We retrospectively investigated the records of 156 patients treated with TAE between January 2007 and December 2021. Rebleeding was defined as the presence of melena, hematemesis, or hematochezia, with a fall (>2.0 g/dl) in hemoglobin level or shock after TAE. The primary outcomes were rebleeding rate and 30-day mortality. RESULTS Seventy patients with peptic ulcer bleeding were selected, and rebleeding within a month after TAE occurred in 15 patients (21.4%). Among the patients included in rebleeding group, significant increases were observed in the prevalence of thrombocytopenia (73.3% vs. 16.4%, p<.001) and ulcers >1 cm (93.3% vs 54.5%, p = .014). The mean AIMS65 (albumin, international normalized ratio, mental status, systolic blood pressure, age >65 years) score (2.3 vs 1.4, p = .009) was significantly higher in the rebleeding group. Multivariate logistic analysis revealed that thrombocytopenia (odds ratio 31.92, 95% confidence interval 6.24-270.6, p<.001) and larger ulcer size (odds ratio 27.19, 95% confidence interval 3.27-677.7, p=.010) significantly increased the risk of rebleeding after TAE. CONCLUSION TAE was effective in the treatment of patients with high-risk peptic ulcer bleeding. AIMS65 score was a significant predictor of rebleeding after TAE, and thrombocytopenia and larger ulcer size increased the risk of rebleeding after TAE.

Abstract
Revaprazan (REV), a novel reversible Proton Pump Inhibitor (PPI) used to treat peptic ulcers, faces challenges in therapeutic efficacy due to its poor dissolution properties and a short half-life. Solid lipid nanoparticles (SLNs) have emerged as a drug delivery system capable of enhancing dissolution and bioavailability of lipid soluble drugs. Here, we report on the development and optimization of a smart gastro-retentive raft system of REV-loaded SLNs (GRS/REV-SLNs) to enhance drug bioavailability and gastric retention. The optimized REV-SLNs had a particle size of 120 nm, a Polydispersity Index (PDI) of 0.313, a zeta potential of -20.7 mV, and efficient drug incorporation of 88 %. Transmission Electron Microscopy (TEM) affirmed the spherical morphology of these REV-SLNs, while Fourier Transform Infrared Spectroscopy (FTIR) revealed no chemical interactions among components. In-vitro assessment of the final GRS/REV-SLNs demonstrated sustained gelation and buoyancy for over 12 h, which would significantly enhance REV retention and its release within the stomach. Further assessments in rats confirmed successful gel transformation within the stomach, resulting in the improved bioavailability of REV. Thus, the development of GRS/REV-SLNs significantly improved the delivery and bioavailability of REV within the stomach, and offers a potentially improved method of treating peptic ulcers.

Abstract
BACKGROUND Peptic ulcer (PU) is an abnormal phenomenon in which there is rupture of the mucosa of the digestive tract, which not only affects patients' normal life but also causes an economic burden due to its high medical costs. AIM To investigate the efficacy of pantoprazole (PPZ) plus perforation repair in patients with PU and its effect on the stress response. METHODS The study subjects were 108 PU patients admitted between July 2018 and July 2022, including 58 patients receiving PPZ plus perforation repair [research group (RG)] and 50 patients given simple perforation repair [control group (CG)]. The efficacy, somatostatin (SS) concentration, stress reaction [malondialdehyde (MDA), lipid peroxide (LPO)], inflammatory indices [tumor necrosis factor (TNF)-α, C-reactive protein (CRP), interleukin (IL)-1β], recurrence, and complications (perforation, hemorrhage, and pyloric obstruction) were compared. RESULTS The overall response rate was higher in the RG than in the CG. Patients in the RG had markedly elevated SS after treatment, which was higher than that of the CG, while MDA, LPO, TNF-, CRP, and IL-1β were significantly reduced to lower levels than those in the CG. Lower recurrence and complication rates were identified in the RG group. CONCLUSION Therefore, PPZ plus perforation repair is conducive to enhancing treatment outcomes in PU patients, reducing oxidative stress injury and excessive inflammatory reactions, and contributing to low recurrence and complication rates.

Abstract
A peptic ulcer is a lesion (sore) on the stomach lining, or duodenum. Peptic ulcers are probably a twentieth-century condition. The ulcer disease continues to be a significant source of worldwide morbidity and mortality. The Gastrointestinal ulcers and duodenal ulcers are considered the two most extreme types of peptic ulcers. Peptic ulcers are found to be caused by an excess of violent factors including Hydrochloric acid (HCL) pepsin, refluxed bile leukotrienes (LT), reactive oxygen species (ROS) and protective factors, these include mucus-bicarbonate barrier functions, prostaglandins (PGs), mucosal blood flow, cell regeneration and migration, non-enzymatic and enzymatic and certain growth factors. The primary cause of peptic ulcer disease is pylori infection and the use of NSAIDs. This review article underscores the importance of a multidisciplinary approach in the management of ulcers to improve patient outcomes and quality of life.

Abstract
Globally, Helicobacter pylori (H. pylori), a stomach pathogen, is present in around 50 % of the population. This bacterial infection produces persistent inflammation, which significantly raises the risk of duodenal, gastric ulcer, and stomach cancer. The goal of this study is to identify the vacA genotypes in H. pylori and analyze how they relate to medical conditions brought on by the bacteria and clarithromycin resistance. PCR was used to describe 115 endoscopic stomach samples from infected patients and identify vacA gene. Of the 115 research participants, H. pylori was found in 81 (70.4 %) of them. Of the isolated cultures, only 38 (69.1 %) were resistant to clarithromycin. VacA was discovered in 55 (67.9 %) of the samples that had H. pylori in them. Patients with gastritis were more likely to have s2m2 strains of infection (66.7 %), while those with gastric and duodenal ulcers were more likely to have s1m1 strains (64.7 %). VacA-positive H. pylori strains (60 % n = 33) were more resistant to clarithromycin versus (19.2 % n = 5) for vacA-negative bacteria. Clarithromycin resistance was significantly linked to vacA s2m2 in H. pylori isolates (75.9 %). According to the study's results, the vacA variants s1m1 and s2m2 have a strong connection with the emergence of H. pylori infections that cause peptic ulcer disease in the population of Iraq. Genetic testing is essential in predicting both the course of treatment and the outcome of H. pylori disease.

Abstract
BACKGROUND Keverprazan is a novel potassium-competitive acid blocker for the treatment of acid-related diseases. AIMS To evaluate the safety, pharmacokinetics, pharmacodynamics, and food effect of single oral doses of keverprazan in healthy Chinese subjects. METHODS In the dose-escalated phase Ia trial, the first 8 subjects received keverprazan 5 mg, the others successively entered 10 mg, 20 mg, 40 mg, 60 mg groups and were randomized to receive keverprazan (n = 8), lansoprazole (LSZ) 30 mg (n = 2) or placebo (n = 2) in each dose group. The phase Ib study randomly enrolled subjects to the fasting-fed (n = 7) or fed-fasting (n = 7) groups for evaluating the food effect of keverprazan. RESULTS Twenty (35.71%) adverse events (AEs) occurred in phase Ia, including 13 (32.50%), 3 (37.50%), and 4 (50.00%) AEs in the keverprazan, placebo, and LSZ groups, respectively. Four (28.57%) AEs occurred in Phase Ib. The Tmax of keverprazan was 1.25-1.75 h. Cmax and AUC increased with the dose, and the t1/2, CL/F were 6.00-7.17 h, 88.8-198 L/h, respectively. The intragastric pH >5 holding-time ratio (HTR) increased with the dose but reached a ceiling at 20 mg. In the 30 mg LSZ and 5-60 mg keverprazan groups, the intragastric pH >5 HTRs during 24 h were 57.1%±26.4%, 7.9%±8.1%, 26.2%±22.8%, 80.2%±8.8%, 88.1%±8.6%, and 93.0%±1.7%, respectively. The geometric mean ratios (90% CI) of Cmax and AUC0-∞ of keverprazan in plasma under the fed vs. fasting state were 126.8% (109.0%-147.5%) and 134.9% (123.8%-146.9%). CONCLUSION Keverprazan is tolerable, and provides significant stable and lasting inhibition efficacy of intragastric acidity at 20 mg.

Abstract
This study aimed to investigate whether the gastroprotective effects of three types of bacterial levans are correlated with their prebiotic-associated anti-inflammatory/antioxidant potentials. Three levans designated as LevAE, LevP, and LevZ were prepared from bacterial honey isolates; purified, and characterized using TLC, NMR, and FTIR. The anti-inflammatory properties of levan preparations were assessed in LPS-stimulated RAW 264.7 cell lines, while their safety and gastroprotective potentials were assessed in Wistar rats. The three levans significantly reduced ulcer number (22.29-70.05 %) and severity (31.76-80.54 %) in the ethanol-induced gastric ulcer model compared to the control (P < 0.0001/each), with the highest effect observed in LevAE and levZ (200 mg/each) (P < 0.0001). LevZ produced the highest levels of glutathione; catalase activity, and the lowest MDA levels (P = 0.0001/each). The highest anti-inflammatory activity was observed in LevAE and levZ in terms of higher inhibitory effect on IL-1β and TNF-α production (P < 0.0001 each); COX2, PGE2, and NF-κB gene expression. The three levan preparations also proved safe with no signs of toxicity, with anti-lipidemic properties as well as promising prebiotic activity that directly correlated with their antiulcer effect. This novel study highlights the implication of prebiotic-mediated systemic immunomodulation exhibited by bacterial levans that directly correlated with their gastroprotective activity.

Abstract
Peptic ulcer disease (PUD) continues to be a cause of significant morbidity and mortality worldwide. Almost two-thirds of PUD cases are asymptomatic. In symptomatic patients, epigastric pain is the most common presenting symptom of PUD, which is manifested by nausea, abdominal fullness, bloating, and dyspepsia. Most PUD cases are associated with the use of COX inhibitors or Helicobacter pylori infection, or both. The traditional management of PUD includes the use of proton pump inhibitors to reduce the gastric acid secretion and antibacterial drugs to combat H. pylori. Timely diagnosis and treatment of PUD are vital to reduce the risk of associated morbidity and mortality, as is prevention of PUD among patients at high risk, including COX inhibitors users and those infected with H. pylori. PDE5 inhibitors have been used for the management of erectile dysfunction and pulmonary hypertension for decades. In recent years, studies have mentioned tremendous pleiotropic effects of PDE5 inhibitors on gastrointestinal, urogenital, musculoskeletal, reproductive, cutaneous, and neurologic disorders. Recent data shows that PDE5 inhibition augments gastric mucosa protection, and here, we review the most recent findings regarding the use of PDE5 inhibitors for the prevention and management of PUD.

Abstract
INTRODUCTION Peptic ulcers with adherent clots are associated with a high-risk of rebleeding and mortality. However, the optimal management of bleeding ulcers with adherent clots remains unclear. We conducted this systematic review and meta-analysis to compare endoscopic therapy and conservative therapy to manage bleeding ulcers with adherent clots. METHODS We systematically searched PubMed, Embase, and Web of Science databases through October 2022 to include all studies comparing the endoscopic and conservative therapeutic approaches for bleeding ulcers with adherent clots. Our primary outcome was rebleeding (overall and 30-day). The secondary outcomes were mortality (overall and 30-day), need for surgery, and length of hospital stay (LOS). The random-effects model was used to calculate the pooled odds ratios (OR) and mean differences (MD) with the corresponding confidence intervals (CI) for proportional and continuous variables, respectively. RESULTS Eleven studies (9 RCTs) with 833 patients (431 received endoscopic therapy vs. 402 received conservative therapy) were included. Overall, endoscopic therapy was associated with lower overall rebleeding (OR 0.41, 95% CI 0.22-0.79, P = 0.007), 30-day rebleeding (OR 0.43, 95% CI 0.21-0.89, P = 0.002), overall mortality (OR 0.47, 95% CI 0.23-0.95, P = 0.04), 30-day mortality (OR 0.43, 95% CI 0.21-0.89, P = 0.002), need for surgery (OR 0.44, 95% CI 0.21-0.95, P = 0.04), and LOS (MD - 3.17 days, 95% CI - 4.14, - 2.19, P < 0.00001). However, subgroup analysis of randomized controlled trials (RCTs) showed no significant difference in overall mortality (OR 0.78, 95% CI 0.24-2.52, P = 0.68) between the two strategies, with numerically lower but statistically non-significant rates of overall rebleeding (7.2% vs. 18.5%, respectively; OR 0.42, 95% CI 0.17-1.05, P = 0.06), statistically lower rate of need for surgery (OR 0.28, 95% CI 0.08-0.96, P = 0.04) with endoscopic therapy compared to conservative therapy. CONCLUSIONS Our meta-analysis demonstrates that endoscopic therapy was overall associated with lower rates of rebleeding (overall and 30-day), mortality (overall and 30-day), need for surgery, and LOS, compared to conservative therapy for the management of bleeding ulcers with adherent clots. However, subgroup analysis of RCTs showed that endoscopic therapy was associated with numerically lower but statistically non-significant rates of overall rebleeding and a statistically lower rate of need for surgery compared to conservative therapy with similar overall mortality rates. Combined treatment with thermal therapy and injection therapy was the most effective treatment modality in reducing rebleeding risk. Further large-scale RCTs are needed to validate our findings.

Abstract
PURPOSE Long-term outcome and prognostic factors of transcatheter embolization for gastroduodenal peptic ulcer bleeding are unknown. This study was conducted to evaluate the clinical outcome and factors associated with early recurrent bleeding and 30-day mortality of transcatheter arterial embolization (TAE) for severe, upper gastroduodenal hemorrhage associated with peptic ulcer and refractory to medical and endoscopic therapy. METHODS A monocenter, retrospective study from 2005 to 2020 including 76 consecutive patients who underwent TAE as first-line therapy for bleeding gastroduodenal peptic ulcers refractory to endoscopic therapy. Patient demographics, endoscopy findings, co-morbidities and interventional procedure findings were recorded. The outcome measures were technical and clinical success, procedure related complications, recurrent bleeding, length of hospital stay, 30-day mortality and overall survival. RESULTS The technical success rate was 96% and the clinical success rate was 65,8%. The rebleeding and 30-day mortality rate were 30,7% and 22,4% respectively. A higher international normalized ratio (INR) was a statistically significant risk factor for 30-day mortality (OR, 7.15; 95% CI, 1.67-30.70; p = 0.008). The mean overall survival was 3.76 years (1.16---5.09; 95% CI); a lower Charlson Comorbidity Index (CCI) and a lower Rockall score were significantly associated with a longer overall survival (HR, 1.24; 95% CI, 1.14-1.35; p = 0.0001; HR, 1.32; 95% CI, 1.10-1.59; p = 0.003) respectively. Early rebleeding was significantly associated with a lower overall survival (HR, 2.72; 95% CI, 1.57-4.71; p = 0.0004). CONCLUSION A higher INR was a significant risk factor with a higher 30-day mortality. A lower CCI, a lower Rockall score and the absence of early rebleeding were significantly associated with a longer overall survival.

Abstract
Peptic ulcers (PU) are one of the commonest yet problematic diseases found to be existing in the majority of the population. Today, drugs from a wide range of therapeutic classes are available for the management of the disease. Still, the complications of the condition are difficult to tackle and the side effect profile is quite a concern. The literature indicates that Toll-like receptors (TLRs) and Semaphorins (SEMAs) have been under study for their various pharmacological actions over the past few decades. Both these signalling pathways are found to regulate immunological and inflammatory responses. Moreover, receptors and signalling molecules from the family of TLRs and SEMAs are found to have bacterial recognition and antibacterial properties which are essential in eradicating Helicobacter pylori (H. pylori), one of the major causative agents of PU. Our understanding of SEMAs, a class of proteins involved in cell signalling, is relatively less developed compared to TLRs, another class of proteins involved in the immune response. SEMAs and TLRs play different roles in biological processes, with SEMAs primarily involved in guiding cell migration and axon guidance during development, while TLRs are responsible for recognizing pathogens and initiating an immune response. Here, in this review, we will discuss in detail the signalling cascade of TLRs and SEMAs and thereby understand its association with PU for future therapeutic targeting. The review also aims at providing an overview of the study that has been into exploring the role of these signalling pathways in the management of PU.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) is one of the leading causes of peptic ulcers, and its treatment is a worldwide challenge. Matrix metalloproteinases and their inhibitors influence the development and healing of peptic ulcers. This study aimed to evaluate the ratios of matrix metalloproteinase-2 (MMP-2) to tissue inhibitor of metalloproteinase-1 (TIMP-1) in patients with peptic ulcers that are sensitive or resistant to H. pylori treatment and compare them with healthy individuals. METHODS In this study, 95 patients were included and divided into two groups sensitive (41 patients) and resistant to treatment (54 patients). The results were compared with a control group of 20 participants with normal endoscopy and H. pylori-negative. After obtaining written informed consent, five ml of venous blood was taken to determine their serum MMP-2 and TIMP-1 levels using an enzyme-linked immunosorbent assay. RESULTS In patients with H. pylori-induced peptic ulcers, the MMP-2/TIMP-1 ratio was significantly higher than the healthy controls (P < 0.05). MMP-2 level was associated with patients' response to treatment (P < 0.05). The MMP-2/TIMP-1 ratio was higher in patients with simultaneous gastric and duodenal ulcers (P < 0.05). CONCLUSION It seems that peptic ulcer disease caused by infection with H. pylori increases the MMP-2/TIMP-1 ratio in patients with peptic ulcers. However, it might not be a good predictor of refractory H. pylori-induced peptic ulcer disease.

Abstract
BACKGROUND AND AIM There is regional variation in the eradication rates of Helicobacter pylori (H. pylori) regimens depending on the local antibiotic resistance patterns. The aim of this study was to compare the efficacies of triple, quadruple and sequential antibiotic therapy in eradicating H. pylori infection. METHODS A total of 296 H. pylori-positive patients were randomized to receive one of the three regimens (triple, quadruple or sequential antibiotic therapy) and eradication rate was assessed by H. pylori stool antigen test. RESULTS The eradication rates of standard triple therapy, sequential therapy and quadruple therapy were 93%, 92.9% and 96.4%, respectively (p = 0.57). CONCLUSION Fourteen days of standard triple therapy, 14 days of bismuth-based quadruple therapy and 10 days of sequential therapy are equally efficacious in eradicating H. pylori and all regimens have optimum H. pylori eradication rates.

Abstract
A considerable portion of the world's population practices fasting, for religious purposes like Ramadan or to adopt a healthier lifestyle such as intermittent fasting. During this period, individuals undergo metabolic changes that alter their internal environment. The literature was analysed to identify a possible relationship between fasting and the development of Helicobacter pylori-induced peptic ulcers. This found that fasting does not affect the incidence of peptic ulcers, and studies that saw an increase in the incidence were not significant. However, remodelling of the gastric environment and increases in concentrations of H. pylori were recorded. There is no relationship between fasting and the risk of developing H. pylori-induced peptic ulcers, suggesting that individuals with uncomplicated ulcers are not at risk of developing further ulcers and can participate in fasts provided they take the recommended measures.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Campomanesia lineatifolia Ruiz & Pavón (Myrtaceae), an edible species found in Brazilian Forest, possesses leaves that are traditionally used for the treatment of gastrointestinal disorders in Brazil. Extracts of C. lineatifolia are rich in phenolics and exhibit antioxidant, and gastric antiulcer properties. Furthermore, Campomanesia spp. have been described to possess anti-inflammatory properties, but studies related to chemical constituents of C. lineatifolia are scarce in the literature. AIM OF THE STUDY This work aims to identify the chemical composition of the phenolic-rich ethanol extract (PEE) from C. lineatifolia leaves and evaluate the anti-inflammatory activity that could be related to its ethnopharmacological use. MATERIALS AND METHODS The high-speed countercurrent chromatography (HSCCC), using an isocratic and a step gradient elution method, and NMR, HPLC-ESI-QTOF-MS/MS were used to isolate and identify the chemicals of PEE, respectively. Lipopolysaccharide-(LPS)-stimulated THP-1 cells were used to evaluate the anti-inflammatory activities from PEE and the two majority flavonoids isolated by measure TNF-α and NF-κB inhibition assays. RESULTS Fourteen compounds were isolated from the PEE, further identified by NMR and HPLC-ESI-QTOF-MS/MS, twelve of them are new compounds, and two others are already known for the species. The PEE, quercitrin and myricitrin promoted a concentration-dependent inhibition of TNF-α, and PEE promoted an inhibition of NF-κB pathway. CONCLUSIONS PEE from C. lineatifolia leaves demonstrated significant anti-inflammatory activity that may be related to the traditional use to treat gastrointestinal disorders.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fridericia chica (Bonpl.) L.G. Lohmann (Bignoniaceae), is a climber native to Brazil, found in all Brazilian biomes. It is mostly known in Brazil as "carajiru," and home medicines made from the leaves have been used to cure disorders including stomach ulcers and other gastrointestinal disorders. AIM OF THE STUDY The objective of the study was to investigate the F. chica hydroethanolic extract of leaves (HEFc) preventative and curative antiulcer gastrointestinal efficacy as well as the mechanisms of action using in vivo rodent models. MATERIALS AND METHODS F. chica was collected in the municipality of Juína, Mato Grosso, and its leaves were used to prepare the extract by maceration technique (70% hydroethanol in the 1:10 ratio, w/v) to obtain the HEFc. The chromatographic analysis of HEFc was carried out by High Performance Liquid Chromatography-Photo Diode Array-Electrospray Ionization-Mass Spectrometry (HPLC-PDA-ESI-MS)- LCQ Fleet™ system. To determine the potential antiulcer potential of HEFc (1, 5 and 20 mg/kg, p.o.), the gastroprotective activity was assessed in various animal models of stomach ulcers caused by acidified ethanol, water constraint stress, indomethacin, (acute), and acid acetic (chronic). Additionally, the prokinetic properties of the HEFC were assessed in mice. The gastroprotective underlying mechanisms were evaluated by the histopathological analysis and determination of gastric secretion (volume, free and total acidity), gastric barrier mucus, activation of PGs, NO, K +ATP channels, α2-adrenoceptor, antioxidant activity (GSH, MPO and MDA), NO and mucosal cytokines (TNF-α, IL-1β, and IL-10) levels. RESULTS The chemical composition of HEFc was analyzed and apigenin, scutellarin, and carajurone were identified. HEFc (1, 5 and 20 mg/kg) showed effect against acute ulcers induced by HCl/EtOH with a reduction in the ulcerated area of 64.41% (p < 0.001), 54.23% (p < 0.01), 38.71% (p < 0.01), respectively. In the indomethacin experiment, there was no change in the doses tested, whereas in the water immersion restraint stress ulcer there was a reduction of lesions at doses of 1, 5, and 20 mg/kg by 80.34% (p < 0.001), 68.46% (p < 0.01) and 52.04% (p < 0.01). HEFc increased the mucus production at doses of 1 and 20 mg/kg in 28.14% (p < 0.05) and 38.36% (p < 0.01), respectively. In the pyloric ligation-induced model of gastric ulceration, the HEFc decreased the total acidity in all doses by 54.23%, 65.08%, and 44.40% (p < 0.05) and gastric secretory volume in 38.47% at dose of 1 mg/kg (p < 0,05) and increased the free acidity at the dose of 5 mg/kg by 11.86% (p < 0.05). The administration of EHFc (1 mg/kg) showed a gastroprotective effect possibly by stimulating the release of prostaglandins and activating K+ATP channels and α2-adrenoreceptors. Also, the gastroprotective effect of HEFc involved an increase in CAT and GSH activities, and a reduction in MPO activity and MDA levels. In the chronic gastric ulcer model, the HEFc (1, 5 and 20 mg/kg) decreased the ulcerated area significantly (p < 0.001) at all doses by 71.37%, 91.00%, and 93.46%, respectively. In the histological analysis, HEFc promoted the healing of gastric lesions by stimulating the formation of granulation tissue and consequently epithelialization. On the other hand, regarding the effect of HEFc on gastric emptying and intestinal transit, it was observed that the extract did not alter gastric emptying, but there was an increase in intestinal transit at the dose of 1 mg/kg (p < 0.01). CONCLUSION These outcomes confirmed the advantages of Fridericia chica leaves for the treatment of stomach ulcers, which are well-known. HEFc was discovered to have antiulcer characteristics through multitarget pathways, which might be related to an increase in stomach defense mechanisms and a decrease in defensive factor. HEFc can be regarded as a potential new antiulcer herbal remedy because of its antiulcer properties, which may be attributed to the mixture of flavonoids, apigenin, scutellarin and carajurone.

Abstract
BACKGROUND To better understand the efficacy and safety of Bifidobacterium quadruple viable tablets in the treatment of helicobacter pylori (H. pylori)-infected peptic ulcer or gastritis patients. METHODS A systematic review of the studies published to June 2022 was performed in English database PubMed, Embase, Chinese database CNKI, Wanfang. There were 17 studies were included in this systematic review and meta-analysis. The outcomes measured included H. pylori eradication rate, changes in clinical symptoms of epigastric pain scores, and the incidence of adverse reactions. RESULTS The results of the fixed effect model showed that the eradication rate of H. pylori in the combination of Bifidobacterium quadruple viable bacteria tablets combined with bismuth-containing conventional quadruple therapy was greater than that of bismuth-containing conventional quadruple therapy, and the difference was statistically significant (OR = 3.73, 95%CI (2.79,5.00), Z = 2.78, P < 0.001; I2 = 0.0%, P > 0.999). The results of random effects model showed that the epigastric pain score of Bifidobacterium quadruple viable bacteria tablets combined with bismuth-containing conventional quadruple therapy was lower than that of bismuth-containing conventional quadruple therapy, and the difference was statistically significant (WMD=-0.70, 95%CI (-1.06,-0.34), Z = 3.82, P < 0.001; I2 = 96.7%, P < 0.001). The results of random effects model showed that the acid reflux score of Bifidobacterium quadruple viable bacteria tablets combined with bismuth-containing conventional quadruple therapy was lower than that of bismuth-containing conventional quadruple therapy, and the difference was statistically significant (WMD=-0.98, 95%CI (-1.70,-0.26), Z = 2.66, P < 0.001; I2 = 99.7%, P < 0.001). CONCLUSIONS The eradication rate of H. pylori by Bifidobacterium quadruple viable bacteria tablets combined with bismuth-containing quadruple therapy is better than that of bismuth-containing quadruple therapy. The improvement of clinical symptoms of patients is better than that of bismuth-containing quadruple therapy, and the incidence of adverse reactions is lower than that of bismuth-containing quadruple therapy. Bifidobacterium quadruple viable bacteria tablet combined with bismuth-containing quadruple therapy was effective and safe. It provides a new way to treat patients with H. pylori.

Abstract
INTRODUCTION Whipple's disease is a rare systemic infection due to an impaired immunological response against T. whipplei in genetically predisposed individuals. Since we previously noted development of H. pylori related complications in some patients with Whipple's disease, our aim was to study the prevalence of H. pylori infection and H. pylori related disorders in Whipple's disease. METHODS Whipple's disease patients diagnosed from Jan-2002 to Dec-2021 and two controls per patient, matched for age, gender, ethnicity and year of H. pylori testing were enrolled. RESULTS 34 patients with Whipple's disease and 68 controls were enrolled. H. pylori infection (13/34 vs 8/68, p<0.01), H. pylori-related gastritis (p<0.01) and gastric atrophy (p = 0.01) were significantly more common in patients with Whipple's disease than controls. H. pylori infection and Whipple's disease were diagnosed synchronously in 6/13 patients, and during follow-up in the remaining 7. Interestingly, these last 7 patients were all on trimethoprim-sulfamethoxazole long-term therapy. Two patients developed H. pylori-related gastric malignancies during follow-up. No patients on doxycycline developed H. pylori infection. CONCLUSIONS H. pylori infection and related disorders are common in patients with Whipple's disease and should always be excluded both at time of diagnosis and during follow-up. These findings should be taken into account when selecting antibiotics for Whipple's disease long-term prophylaxis.

Abstract
Acute upper gastrointestinal bleeding (AUGIB) is a clinically common emergency condition. The common causes of AUGIB are peptic ulcer and esophagogastric variceal bleeding. Despite continuous improvements in endoscopic hemostasis techniques, endoscopic treatment is still unsuccessful in 5%-15% of patients. Hemostatic powder, a new drug for endoscopic hemostasis that is sprayed on the bleeding site with the assistance of an air pump, can absorb water to promote clotting substance aggregation and then adhere over the lesion, forming a mechanical barrier and then achieving hemostasis. It is convenient to spray hemostatic powder under endoscopy, where precise positioning is not warranted. The immediate hemostasis rate of hemostatic powder is often high, and it can be used as a remedy after the failure of conventional hemostasis. However, until now, there have been no recommendations in China regarding the use of hemostatic powder for the treatment of AUGIB. This article summarizes the mechanism, clinical applicability, and side effects of five major types of hemostatic powder by reviewing the existing evidence, with an aim to strengthen endoscopists' understanding of this drug.

Abstract
INTRODUCTION Refractory peptic ulcer is now a rare disease since most peptic ulcers heal with appropriate treatment with proton pump inhibitors (PPIs) and/or Helicobacter pylori eradication. AREAS COVERED The most frequent cause of apparent refractoriness is lack of adherence to treatment. Persistence of H. pylori infection, use or abuse (often surreptitious) of high dose non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin (ASA) are the two major causes of true refractory ulcers. There is a growing number of peptic ulcers which are not linked to either NSAIDs or H. pylori infection. Refractoriness in these ulcers can be linked to gastric acid hypersecretion, rapid PPI metabolization, ischemia, chemo-radiotherapy, immune diseases, more rarely to other drugs or be fully idiopathic. Treatment of the cause of the ulcer, if known, is essential. This review is based on pertinent publications retrieved by a selective search in PubMed, with particular attention to refractory peptic ulcer. EXPERT OPINION High-dose PPI or the new potassium competitive acid blocker or the combination of PPIs with misoprostol can be recommended in these cases. Other more experimental treatment such the topical application of platelet- rich- plasma, or mesenchymal stem cells have also been suggested. Surgery is the last option, but there is no guarantee of success, especially in NSAID or ASA abusers.

Abstract
BACKGROUND Marginal ulcer bleeding (MUB) is a complication that can occur following several types of surgery. However, few studies exist on it. Therefore, this study aimed to compare the clinical outcomes of MUB with those of peptic ulcer bleeding (PUB). METHODS Between January 2013 and December 2017, 5,076 patients underwent emergent esophagogastroduodenoscopy for suspected upper gastrointestinal bleeding. We retrospectively reviewed and analyzed the medical records of MUB and PUB patients and developed a propensity score matching (PSM) method to adjust for between-group differences in baseline characteristics with 1:2 ratios. Sex, age, body mass index (BMI), underlying diseases, and drugs were included as matching factors. RESULTS A total of 64 and 678 patients were diagnosed with MUB and PUB, respectively, on emergent esophagogastroduodenoscopy, and 62 and 124 patients with MUB and PUB, respectively, were selected after PSM. Rebleeding was significantly higher in patients with MUB than in those with PUB (57.8% vs 9.1%, p < 0.001). Mortality caused by bleeding was higher in patients with MUB than in those with PUB (4.7% vs. 0.4%, p < 0.001). Multivariate analysis revealed that proton pump inhibitor (PPI) administration (odds ratio [OR], 0.14; 95% confidence interval [CI], 0.03-0.56; p = 0.011) after first bleeding was inversely correlated with MUB rebleeding. Large ulcer size (> 1 cm) (OR, 6.69; 95% CI, 1.95-27.94; p = 0.005) and surgery covering pancreas (OR, 3.97; 95% CI, 1.19-15.04) were independent risk factors for MUB rebleeding. CONCLUSIONS MUB showed a severe clinical course than PUB. Therefore, MUB should be managed more cautiously, especially for large ulcers and pancreatic surgery. Prophylactic PPI administration may be helpful in reducing rebleeding in MUB.

Abstract
Abstract Double pylorus is one of the rare endoscopic findings consisting of two communication channels between the gastric antrum and the first part of the duodenum. It has no specific signs and symptoms. It is usually detected incidentally during endoscopic examination performed with nonspecific dyspeptic complaints such as epigastric pain, nausea, vomiting, and bloating. But contrary to expectations our patient applied to the emergency department with the complaint of melena that had been going on for 3 days. Her hemoglobin value was 9.7 mg/dL, blood ure nitrogen value was 65 mg/dL. Rectal touch examination was compatible with melena. In the emergency endoscopy of the patient, two channels were seen in the pylorus region. In the accessory canal, there was an ulcer of 10 mm in size with adherent dots and white exudate. The biopsy was reported as chronic gastritis due to H.pylori infection. Ibuprofen treatment used by the patient was discontinued and the patient was given high double dose PPI and H.pylori eradication therapy. Double pylorus, which is usually found incidentally in endoscopy with nonspecific findings, may very rarely present with GI bleeding findings, as in our patient. It is necessary to avoid risk factors in double pylorus, to give antiulcer and H.pylori treatment in its presence for an optimal time regardless of whether the double pylorus continues or not.

Abstract
Proton pump inhibitors (PPIs) have several limitations to their efficacy including insufficient acid suppression, slow onset of action, and variable efficacy among patients due to CYP2C19 metabolism. Potassium-competitive acid blockers inhibit H+-K+-ATPase in a reversible and K+-competitive manner, are novel acid suppressive drugs with rapid onset of action, meal independence, and prolonged control of intragastric acidity compared to PPIs. Potassium-competitive acid blockers exhibited non-inferior therapeutic efficacies on reflux esophagitis, gastric ulcers, and Helicobacter pylori eradication. The review is focused on the unmet needs across the acid-related diseases and recent updates on clinical studies using vonoprazan and tegoprazan.

Abstract
BACKGROUND An ulcer is a condition characterized by inflammation, irritation, or erosion in the mucosal lining of the stomach or duodenum. Hence, peptic ulcer is the ulcer of both the stomach and the duodenum. 10% of the world's population is affected by chronic peptic ulcers. The formation of peptic ulcers depends on gastric juice pH and the decrease in mucosal defenses. Nonsteroidal anti-inflammatory drugs (NSAIDs) and Helicobacter pylori (H. pylori) infection are the two significant factors disrupting mucosal resistance to injury. Indian herbal plants are exceptional for their ethnic, ethnobotanical, and ethno-pharmaceutical use. In this review, attempts have been made to gain information regarding some plants that may be used to treat or prevent peptic ulcers. The ultimate goal of peptic ulcer disease treatment is to reduce pain, cure ulcers, and prevent recurrence. OBJECTIVE The aim of the study was to gain knowledge about several common medicinal plants employed in Ayurveda or contemporary science for the treatment or prevention of peptic ulcers and some natural and simple approaches to cure ulcers using readily available herbs. METHOD The literature search was carried out using search engines, like Google Scholar, Scopus, PubMed, Medline, Springer, etc. Results: The extensive literature search showed natural herbs to have potential anti-ulcer activity, including cabbage, bananas, liquorice, fenugreek, garlic, Terminalia chebula, Acacia arabica, Aegle marmelos, Aloe vera, Allium sativum, Plantago ispagula, Mimosa pudica, Annona squamosa, Azadirachta indica, and Galega purpurea. CONCLUSION This study concluded several medicinal plants to effectively prevent or cure peptic ulcers caused by a variety of factors, including H. pylori, aspirin, indomethacin, alcohol, and others.

Abstract
Background The study aimed to calculate the predictive value of admission laboratory values in patients with perforated peptic ulcers. Methods A retrospective, cohort analytical, observational study was performed, including patients with surgically confirmed perforated peptic ulcers over a 5-year period. Demographic data and admission laboratory values were collected from hospital electronic databases. Outcomes measured were in-hospital mortality, intensive care unit (ICU) admission and length of stay. The significance of categorical variables was calculated by chi-square and Fisher's exact test. Logistic regression analysis was performed to determine univariately statistically significant variables. Results In total, 188 patients met the inclusion criteria. The median age was 46 (range 15-87) years with a male predominance of 71.3 % (n = 134). The median length of hospital stay was 7 (range 1-94) days and 31.4 % (n = 59) of patients were admitted to the ICU. Post-operative in-hospital mortality was 25.0 % (n = 47). Predicting the categorical outcome of in-hospital mortality, abnormal haemoglobin, platelet count, urea, creatinine and potassium levels were all found to be statistically significant in the univariate analysis. Age (odds ratio [OR] 1.03), haemoglobin (OR 4.36) and creatinine (OR 7.76) levels were significant in the multivariate analysis. Conclusions Mortality rate among patients with perforated peptic ulcer disease is still substantial. Admission laboratory values showed statistical significance as outcome indicators and were valuable to assist in predicting the prognosis. An abnormally high serum creatinine level was the strongest single predictor of both mortality and ICU admission. Key message Initial laboratory findings of patients admitted for perforated peptic ulcer showed that an abnormally high serum creatinine level was the strongest single predictor of both mortality and ICU admission.

Abstract
BACKGROUND A perforated gastroduodenal ulcer is rarely observed in children. Certain medications have been reported to cause ulcerations. Deferasirox, an iron chelating agent, has been previously reported to be associated with the development of gastroduodenal ulcers.
CASE SUMMARY We report a case of a 3-year-old boy who was diagnosed with beta thalassemia major and treated with deferasirox. He presented to the emergency department with an acute abdomen. A perforated duodenal ulcer was suspected after X-ray imaging and laparoscopic exploration. It was successfully managed with laparoscopic washout and drainage.
CONCLUSION Due to the rarity and severity of this case, it is a reminder that prevention and early recognition of gastrointestinal complications in patients receiving deferasirox are crucial. Minimally invasive laparoscopic surgery is both safe and feasible to treat perforated duodenal ulcers in selected patients.

Abstract
BACKGROUND The ability of endoscopists to identify gastric lesions is uneven. Even experienced endoscopists may miss or misdiagnose lesions due to heavy workload or fatigue or subtle changes in lesions under white-light endoscopy (WLE). This study aimed to develop an artificial intelligence (AI) system that could diagnose six common gastric lesions under WLE and to explore its role in assisting endoscopists in diagnosis. METHODS Images of early gastric cancer, advanced gastric cancer, submucosal tumor, polyp, peptic ulcer, erosion, and lesion-free gastric mucosa were retrospectively collected to train and test the system. The performance of the system was compared with that of 12 endoscopists. The performance of endoscopists with or without referring to the system was also evaluated. RESULTS A total of 29,809 images from 8947 patients and 1579 images from 496 patients were used to train and test the system, respectively. For per-lesion analysis, the overall accuracy of the system was 85.7%, which was comparable to that of senior endoscopists (85.1%, P = 0.729) and significantly higher than that of junior endoscopists (78.8%, P < 0.001). With system assistance, the overall accuracies of senior and junior endoscopists increased to 89.3% (4.2%, P < 0.001) and 86.2% (7.4%, P < 0.001), respectively. Senior and junior endoscopists achieved varying degrees of improvement in the diagnostic performance of other types of lesions except for polyp. The diagnostic times of senior (3.8 vs 3.2 s per image, P = 0.500) and junior endoscopists (6.2 vs 4.6 s per image, P = 0.144) assisted by the system were both slightly shortened, despite no significant differences. CONCLUSIONS The proposed AI system could be applied as an auxiliary tool to reduce the workload of endoscopists and improve the diagnostic accuracy of gastric lesions.

Abstract
BACKGROUND Helicobacter pylori eradication is associated with reduced gastric cancer and peptic ulcer disease incidence and mortality. Factors influencing patients' experiences surrounding H. pylori diagnosis and management are not well-described. Current patient perceptions can influence adherence to treatment, and also their anxieties related to this potentially carcinogenic condition. The objective of this study was to understand the patient experience surrounding H. pylori management and to qualitatively construct a contextual framework to inform and guide providers who manage patients with H. pylori infection. METHODS We conducted a qualitative analysis using a focus group and one-on-one telephone interviews. An iterative inductive/deductive approach was applied to recorded transcripts to identify and hierarchically order themes. Patient experience was defined according to major themes within a structured health behavior framework. RESULTS Theme saturation was achieved with thirteen participants (mean age 50.4 years; 62% female; 38% non-Hispanic white). Qualitative analysis yielded a total of 987 codes that resulted in five major themes related to the patient H. pylori experience: context of decision-making; health beliefs; barriers experienced; cues to action; and impact of new knowledge. These themes aligned with the Health Behavior Model framework. Participants were motivated to treat H. pylori. However, the experience was more often perceived negatively versus positively. The perceived patient-provider interaction contributed most prominently to the negative experience compared to other patient experiences, including treatment-related side effects. Internal cues, including symptoms and fear of cancer, modified participants' perceptions and motivation to accept treatment. CONCLUSIONS Patient experiences related to H. pylori management are predominantly negative. Increasing providers' awareness about patients' values, beliefs, anxieties, and expectations surrounding H. pylori diagnosis/treatment may improve provider-patient communication and, ideally, related outcomes.

Abstract
BACKGROUND Thyroid storm is an uncommon condition manifesting in severe thyrotoxicosis with a high mortality rate. The concurrence of peptic ulcer disease and hyperthyroidism is rare due to concurrent activation of both the sympathetic and parasympathetic pathways. We present a case of perforated giant gastric ulcer with concurrent thyroid storm who underwent damage control surgery with emergency patch repair with falciform ligament and recovered well.
CASE SUMMARY A 53-year-old male chronic smoker, with no previous medical history, presented with severe generalized abdominal pain and vomiting for one day duration. Further history revealed weight loss, diarrhea, and anxiety over the past three months. On clinical examination, patient was febrile with temperature of 38.6 Degrees Celsius and tachycardic at 130-140 beats per minute, his blood pressure was low at 90/50mmHg. His abdomen was tender with generalized peritonism. In view of his clinical history, a thyroid screen was ordered which showed raised thyroxine (T4) levels of 90.3 pmol/L and low thyroxine stimulating hormone (TSH) levels of 0.005 μU/mL. Chest X-ray showed no sub-diaphragmatic free air, but contrasted CT scan revealed pneumoperitoneum with large amount of intraabdominal free fluid. The working diagnosis was perforated peptic ulcer complicated by thyroid storm. An urgent endocrinologist consult was made, and patient was started on beta blocker and intravenous steroids pre-operatively. The patient underwent emergency laparotomy with washout and patch repair of the perforated gastric ulcer. Patient was monitored post-operatively in intensive care unit and required IV hydrocortisone and Lugol’s iodine. Histology of the ulcer edges showed no malignancy. On post-operative day seven, T4 decreased to 20.4 pmol/L, TSH was 0.005 mLU/L. His thyroid function test subsequently normalized 3 mo post-operatively with T4 18.1 pmol/L, TSH 1.91 mLU/L. Patient’s recovery was otherwise uneventful. Thyroid receptor antibody subsequently was positive, and patient was managed for Grave’s disease by the endocrinologist.
CONCLUSION This case highlights the rare but life-threatening clinical emergency of peptic ulcer perforation complicated by thyroid storm. Multidisciplinary perioperative management is crucial to optimize patient for surgery and damage control principles should be taken for an acute surgical patient with concurrent endocrine crisis.

Abstract
Gastroduodenal inflammation and ulcerative injuries are increasing due to expanding socio-economic stress, unhealthy food habits-lifestyle, smoking, alcoholism and usage of medicines like non-steroidal anti-inflammatory drugs. In fact, gastrointestinal (GI) complications, associated with the prevailing COVID-19 pandemic, further, poses a challenge to global healthcare towards safeguarding the GI tract. Emerging evidences have discretely identified mitochondrial dysfunctions as common etiological denominators in diseases. However, it is worth realizing that mitochondrial dysfunctions are not just consequences of diseases. Rather, damaged mitochondria severely aggravate the pathogenesis thereby qualifying as perpetrable factors worth of prophylactic and therapeutic targeting. Oxidative and nitrosative stress due to endogenous and exogenous stimuli triggers mitochondrial injury causing production of mitochondrial damage associated molecular patterns (mtDAMPs), which, in a feed-forward loop, inflicts inflammatory tissue damage. Mitochondrial structural dynamics and mitophagy are crucial quality control parameters determining the extent of mitopathology and disease outcomes. Interestingly, apart from endogenous factors, mitochondria also crosstalk and in turn get detrimentally affected by gut pathobionts colonized during luminal dysbiosis. Although mitopathology is documented in various pre-clinical/clinical studies, a comprehensive account appreciating the mitochondrial basis of GI mucosal pathologies is largely lacking. Here we critically discuss the molecular events impinging on mitochondria along with the interplay of mitochondria-derived factors in fueling mucosal pathogenesis. We specifically emphasize on the potential role of aberrant mitochondrial dynamics, anomalous mitophagy, mitochondrial lipoxidation and ferroptosis as emerging regulators of GI mucosal pathogenesis. We finally discuss about the prospect of mitochondrial targeting for next-generation drug discovery against GI disorders.

Abstract
Background Perforated peptic ulcer (PPU) is a common emergency condition requiring surgery using laparoscopy or open repair of the perforated site. The aim of this study was to assess the role of laparoscopic surgery (LS) based on the safety and efficacy for PPU. Methods Medical records of the consecutive patients who underwent LS or open surgery (OS) for PPU at five hospitals between January 2009 and December 2019 were retrospectively reviewed. After propensity score matching, short-term perioperative outcomes were compared between LS and OS in selected patients. Results Among the 598 patients included in the analysis, OS was more frequently performed in patients with worse factors, including older age, a higher American Society of Anesthesiologists score, more alcohol use, longer symptom duration, a higher Boey score, a higher serum C-reactive protein level, a lower serum albumin level, and a larger-diameter perforated site. After propensity score matching, 183 patients were included in each group; variables were well-balanced between-groups. Postoperative complications were not different between groups (24.6% LS group vs. 31.7% OS group, p = 0.131). However, postoperative length of hospital stay (10.03 vs. 12.53 days, respectively, p = 0.003) and postoperative time to liquid intake (3.75 vs. 5.26 days, p < 0.001) were shorter in the LS group. Conclusions LS resulted in better functional recovery than OS and can be safely performed for treatment of PPU. When performed by experienced surgeons, LS is an alternative option, even for hemodynamically unstable patients.

Abstract
UNLABELLED Oral bisphosphonates and direct oral anticoagulants are related to upper gastrointestinal ulcers. The present study investigated whether concomitant use of these drugs increase the risk of upper gastrointestinal ulcers and report no increased risk of upper gastrointestinal ulcers compared to the use of either drug alone, when individuals with previous upper gastrointestinal ulcers are excluded. INTRODUCTION This study examines whether concomitant use of oral bisphosphonates (oBP) and direct oral anticoagulants (DOAC) increases the risk of peptic ulcers more than any drug alone. METHODS A population-based cohort study was performed. We sampled a cohort of oBP and DOAC users from a sample of 2,622,742 individuals, consisting of diabetes patients and age- and gender-matched controls, obtained from the Danish National Patient Register. The exposures were concomitant use of oBP and DOAC and single use of DOAC and single use of oBP. The primary endpoint was the first incident peptic ulcer. Information on exposure and outcome were collected from national registries. The period of observation was from 01.01.2008 until 31.12.2018. Unadjusted and adjusted Cox regressions were performed. RESULTS 8077 individuals received concomitant treatment with DOAC and oBP; 96,451 individuals used DOAC and no oBP; and 118,675 used oBP and no DOAC. The mean duration of follow-up was 1.9 years for concomitant users, 2.5 years for DOAC users, and 4.5 years for oBP users. A total of 4742 individuals with incident peptic ulcers were collected. We observed an increased risk of incident ulcer in users of DOAC and oBP compared to single DOAC treatment in the adjusted analysis (HR = 1.23, 95% CI: 1.03; 1.48). However, the effects were abolished when excluding individuals with a previous ulcer. We observed an increased risk of incident ulcer in users of DOAC and oBP compared to users of oBP in the adjusted model (HR = 1.34, 95% CI: 1.11; 1.63). CONCLUSION Based on our results, concomitant use of oBP and DOAC is associated with a slight increase in the risk of peptic ulcers compared to either drug alone. The prescribing physician should weigh the slight increased risk of ulcer in concomitant users of oBP and DOAC with beneficial reductions in stroke and fractures.

Abstract
BACKGROUND Peptic ulcer perforation is a common life-threatening surgical emergency. Graham omental patch is performed for plugging of perforated peptic ulcer. Many endoscopic methods have been used to treat acute perforated peptic ulcer such as over the scope clips, standard endoscopic clips, endoscopic sewing and metallic stents. The main idea in endoscopic management of acute perforated peptic ulcer is early decontamination and decrease sepsis by interventional radiologic drainage. METHODS This is a prospective randomized controlled clinical trial. This study included patients who were developed acute perforated peptic ulcer manifestations and were admitted to our hospital between December 2019 and August 2021. Sample size was 100 patients divided into 2 equal groups. Endoscopic group (EG): included 50 patients who were subjected to endoscopic management. Surgical group (SG): included 50 patients who were subjected to surgical management. RESULTS One hundred patients were randomized into 2 groups: SG (50) and EG (50). Median age of patients was 36 (range 27:54) and 47 (range 41:50) years-old in SG and EG, respectively. Males constituted 72% and 66% in SG and EG, respectively. Median length of postoperative hospital stay was 1 (range: 1-2) days in EG, while in SG was 7 (range 6-8) days. Postoperative complications in SG patients were 58% in form of fever, pneumonia, leak, abdominal abscess, renal failure and incisional hernia (11%, 5%, 5%, 3%, 2% and 3%, respectively). Postoperative complications in EG patients were 24% in form of fever, pneumonia, leak, abdominal abscess, renal failure and incisional hernia (10%, 0%, 2%, 0%, 0% and 0%, respectively). CONCLUSION Combined endoscopic and interventional radiological drainage can effectively manage acute perforated peptic ulcer without the need for general anesthesia, with short operative time, in high risk surgical patients with low incidence of morbidity & mortality.

Abstract
Annular pancreas is a rare congenital anomaly in which a thin band of pancreatic tissue partially or completely surrounds the duodenum. It is challenging to diagnose due to its variable clinical presentation. Approximately two-thirds of patients have no symptoms in their lifetime, and most symptomatic cases are seen in neonates and infants. Symptomatic adult patients present with upper gastrointestinal symptoms, such as epigastric pain, vomiting, and postprandial fullness associated with gastric outlet obstruction. Complications associated with annular pancreas include peptic ulcer disease, pancreatitis, pancreatic head carcinoma, and biliary obstruction. Annular pancreas is also a rare cause of upper gastrointestinal bleeding in adults, but it should be considered as one of the differential diagnoses in patients presenting with a peptic ulcer and duodenal stricture. Here, we report the case of a 60-year-old man who presented with melena and was subsequently diagnosed with an annular pancreas.

Abstract
Found in humid regions and waterways and popularly used to treat gastrointestinal problems among other applications, the present study evaluated the M. aquatica essential oil (OEMa) as a therapeutic alternative to treat gastrointestinal disorders. Produced by steam distillation, chemical composition of OEMa was determined by GC-MS analysis. The ethanol-induced ulcer and the dose-repeated acetylsalicylic acid (ASA)-induced gastrointestinal lesions models in rats evaluated, respectively, the prophylactic and curative effects of EOMa on peptic ulcers. The EOMa's effect on gastric secretion, gastric mucus and gastrointestinal motility were evaluated in in vivo models. The curative effect of EOMa on acute colitis was evaluated using the DSS-induced colitis model in mice. Obtained in 0.17% yield (w/w), with carvone (54.82 ± 1.39 g/100 g oil) as the main constituent, EOMa (at 75 mg/kg) showed potent gastroprotective effect (> 90%) mediated by non-protein sulfhydryl compounds (NPSH) and nitric oxide (NO) modulation alongside reduction in gastric secretion volume and total acidity. EOMa did not affect gastric mucus production and gastrointestinal motility. In dose-repeated ASA-induced gastrointestinal lesions model, EOMa (at 25 mg/kg) promoted the inflammatory process resolution both in gastric and duodenal walls by modulating NPSH, NO and myeloperoxidase levels. Despite delaying in 2 days the clinical symptoms worsening, EOMa (at 25 mg/kg) was not able to protect colon tissues from DSS-induced acute colitis as evidenced by macroscopic, biochemical, and histopathological parameters. This is the first report of Mentha aquatica essential oil as a promising herbal medicine for peptic ulcers treatment together with an adjuvant effect in IBD.

Abstract
BACKGROUND Acute non-variceal bleeding accounts for approximately 20% of all-cause bleeding episodes in patients with liver cirrhosis. It is associated with high morbidity and mortality therefore prompt diagnosis and endoscopic management are crucial.
AIM To evaluate available data on the efficacy of endoscopic treatment modalities used to control acute non-variceal gastrointestinal bleeding (GIB) in cirrhotic patients as well as to assess treatment outcomes.
METHODS Employing PRISMA methodology, the MEDLINE was searched through PubMed using appropriate MeSH terms. Data are reported in a summative manner and separately for each major non-variceal cause of bleeding.
RESULTS Overall, 23 studies were identified with a total of 1288 cirrhotic patients of whom 958/1288 underwent endoscopic therapy for acute non-variceal GIB. Peptic ulcer bleeding was the most common cause of acute non-variceal bleeding, followed by portal hypertensive gastropathy, gastric antral vascular ectasia, Mallory-Weiss syndrome, Dieaulafoy lesions, portal hypertensive colopathy, and hemorrhoids. Failure to control bleeding from all-causes of non-variceal GIB accounted for less than 3.5% of cirrhotic patients. Rebleeding (range 2%-25%) and mortality (range 3%-40%) rates varied, presumably due to study heterogeneity. Rebleeding was usually managed endoscopically and salvage therapy using arterial embolisation or surgery was undertaken in very few cases. Mortality was usually associated with liver function deterioration and other organ failure or infections rather than uncontrolled bleeding. Endoscopic treatment-related complications were extremely rare. Lower acute non-variceal bleeding was examined in two studies (197/1288 patients) achieving initial hemostasis in all patients using argon plasma coagulation for portal hypertensive colopathy and endoscopic band ligation or sclerotherapy for bleeding hemorrhoids (rebleeding range 10%-13%). Data on the efficacy of endoscopic therapy of cirrhotic patients vs non-cirrhotic controls with acute GIB are very scarce.
CONCLUSION Endotherapy seems to be efficient as a means to control non-variceal hemorrhage in cirrhosis, although published data are very limited, particularly those comparing cirrhotics with non-cirrhotics and those regarding acute bleeding from the lower gastrointestinal tract. Rebleeding and mortality rates appear to be relatively high, although firm conclusions may not be drawn due to study heterogeneity. Hopefully this review may stimulate further research on this subject and help clinicians administer optimal endoscopic therapy for cirrhotic patients.

Abstract
Proton pump inhibitors are widely used throughout the world for the treatment of gastrointestinal disorders that are related to acid secretion, such as peptic ulcer disease and dyspepsia. Another common indication for proton pump inhibitors is stress ulcer prophylaxis. Proton pump inhibitors have proven efficacy for the treatment of acid-related gastrointestinal disorders, but there is concern that their use may be associated with the development of significant complications, such as fractures, Clostridium difficile infection, acute kidney injury, chronic kidney disease, and hypomagnesemia. Proton pump inhibitors are overused in the hospital setting, both for stress ulcer prophylaxis and gastrointestinal bleeding, and then they are often inappropriately continued after discharge from the hospital. This narrative review article outlines the evidence surrounding appropriate proton pump inhibitor use for stress ulcer prophylaxis and peptic ulcer bleeding.

Abstract
OBJECTIVE To explore the relationship between high altitude polycythemia (HAPC) and peptic ulcer bleeding, in order to provide the evidence for the clinical diagnosis and treatment of peptic ulcer disease in Tibet of China. METHODS A retrospective case-control study was conducted. Patients who hospitalized in the Department of Gastroenterology with the diagnosis of peptic ulcer bleeding from January 1, 2015 to April 30, 2021 in Tibet Autonomous Region People's Hospital were enrolled in the case group, and patients who hospitalized in the Department of Urology without tumor and without the history of peptic ulcer and gastrointestinal bleeding during the same period were selected as the control group. In the study, 1 ∶ 1 case matching was conducted between the two groups according to the gender, age (±2 years), ethnic group (Tibetan, Han), and the residence altitude level (grouped by < 4 000 m or ≥4 000 m), and 393 cases were included in the case group and the control group respectively. All the patients had lived in Tibet with the altitude >2 500 m for more than 1 year, and with age ≥ 18 years. The risk factors of peptic ulcer bleeding (place of residence, smoking, alcohol, the use of NSAIDs/anticoagulants, and combined with chronic diseases, such as HAPC, hypertension, diabetes mellitus, heart disease, hyperlipidemia, cerebrovascular disease, chronic lung disease, joint disease) were analyzed and compared between the two groups. RESULTS There were 28 (7.1%) patients with HAPC in the case group, and 5 (1.3%) in the control group. The incidence of HAPC in the case group was significantly higher than those in the control group, P < 0.001, and the OR value was 5.953. Multivariate Logistic regression analysis showed that HAPC (OR=5.270, 95%CI: 1.806-15.380), living in cities and towns (OR=2.369, 95%CI: 1.559-3.602), alcohol (OR=3.238, 95%CI: 1.973-5.317) and the use of NSAIDs/anticoagulants (OR=20.584, 95%CI: 2.639-160.545) were the independent risk factors for peptic ulcer bleeding in Tibet. After adjusting for the possible confounding factors, such as living in cities and towns, alcohol, and the use of NSAIDs/anticoagulants, HAPC was associated with an increased risk of peptic ulcer bleeding in Tibet, and the OR value was 5.270. CONCLUSION HAPC was associated with a significantly increased risk of peptic ulcer bleeding in Tibet. Patients with HAPC and peptic ulcer should be diagnosed and treated actively, in order to avoid gastrointestinal bleeding and other serious complications.
