Case Study of a Refractory Idiopathic Peptic Ulcer in Which 24-h Intragastric pH Monitoring Contributed to Its Pathophysiological Analysis. Case Rep Gastroenterol 2024; 18:386-394.

Abstract
Introduction In recent years, the frequency of idiopathic peptic ulcers (IPUs) has increased. However, the clinicopathological characteristics of IPU have not been fully elucidated and treatment methods for recurrent and refractory cases have not yet been established. Case Presentation A man in his forties complained of epigastric discomfort. Esophagogastroduodenoscopy revealed a gastric ulcer in the lesser curvature of the gastric angle. After Helicobacter pylori was eradicated, the gastric ulcer recurred despite the administration of a potassium competitive acid blocker (PCAB), and a diagnosis of IPU was made. Twenty-four-hour intragastric pH monitoring revealed insufficient gastric acid suppression. Misoprostol was added to the patient's treatment. Subsequently, the ulcer healed and recurrence was not observed. Conclusion For refractory IPU, the evaluation of pathophysiological function through 24-h gastric pH monitoring may lead to the selection of an appropriate treatment. If a proton pump inhibitor and PCAB do not improve the IPU, combination treatment with misoprostol may be considered as an option.

O'Connor HJ. Forty years of Helicobacter pylori infection and changes in findings at esophagogastroduodenoscopy. Helicobacter 2023; 28:e13026. [PMID: 37818739 DOI: 10.1111/hel.13026] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 09/24/2023] [Accepted: 09/26/2023] [Indexed: 10/13/2023]
Abstract
BACKGROUND It is 40 years since the discovery of Helicobacter pylori infection. Over that time major changes have occurred in esophagogastroduodenoscopy (EGD) findings. The aim of this review is to describe these changes, and the important role H. pylori infection has played in their evolution. METHODS References were identified through searches of PubMed using the search terms-endoscopy time trends, peptic ulcer disease, gastroesophageal reflux disease, upper gastrointestinal cancer, gastric polyps, H. pylori, eosinophilic gastrointestinal disorders, and celiac disease, from 1970 through December 2021. RESULTS The prevalence of H. pylori infection has fallen and consequently, H. pylori-positive peptic ulcer disease has become rare. Gastroesophageal reflux disease is now the commonest disorder diagnosed at EGD, and Barrett's esophagus has increased in parallel. Cancer of the distal stomach has fallen while esophageal adenocarcinoma and reflux-related cardia cancer have risen. Gastric polyps have changed from hyperplastic and adenomas to sporadic fundic gland polyps. Antimicrobial resistance has made H. pylori infection more difficult to eradicate. Eosinophilic gastrointestinal disorders, particularly eosinophilic esophagitis, have emerged as important new allergic disorders. Celiac disease has changed and increased. CONCLUSIONS EGD findings appear to have changed from features suggesting a H. pylori-positive "phenotype" 40 years ago to a H. pylori-negative "phenotype" today. These changes have major implications for the management of gastrointestinal disorders.

Abstract
Background Helicobacter pylori infection is the most common cause of peptic ulcer disease. However, the prevalence rates of non-helicobacter pylori idiopathic peptic ulcers have increased over the past few years. This study aims to compare the characteristics of Helicobacter pylori-positive with idiopathic duodenal ulcers. Methods A cross-sectional cohort study was conducted on 950 patients which were excluded from the analysis process duo to the concomitant presence of gastric ulcer, malignancy, Zollinger Ellison syndrome, Crohn's disease, esophageal varices, history of taking anti-Helicobacter pylori therapy, and history of taking NSAID or aspirin. Eventually, 647 subjects were enrolled for the analysis process. In this case, these subjects were divided into two groups: (I) Helicobacter pylori-positive ulcer group and (II) Helicobacter pylori-negative and non-NSAID (idiopathic) ulcer group. Results The findings showed that 417 patients (64.5%) had duodenal ulcers induced by Helicobacter pylori, and 111 patients (17.1%) had Helicobacter pylori-negative and non-NSAID ulcers. The mean ages of patients in Helicobacter pylori-positive and idiopathic ulcer groups were 39±15 and 42±17, respectively. In this case, 33 patients (29.7%) with idiopathic ulcers and 56 patients (25.1%) with Helicobacter pylori-positive ulcers had upper gastrointestinal bleeding. Also, 22 patients (21%) with idiopathic ulcers and 31 patients (16.5%) with Helicobacter pylori-positive ulcers had multiple duodenal ulcers. Conclusion The present study demonstrated that the idiopathic ulcers included 17.1% of duodenal ulcers. Also, it was concluded that patients with idiopathic ulcers were predominantly male with an age range older than the other group. In addition, patients in this group had more ulcers.

Abstract
Erosive and ulcerative lesions of the digestive tract are one of the most pressing problems in the clinic of internal diseases due to the extremely widespread prevalence, the presence of severe complications, often fatal, diagnostic difficulties due to the presence of a large number of asymptomatic pathologies and difficulties in the rational choice of therapy. Particularly noteworthy is the data that during the global pandemic of Covid-19 infection, it is capable, quite often, of causing the development of erosive and ulcerative lesions of the gastrointestinal tract. In this regard, it seems important to use drugs that can not only prevent the occurrence of erosive and ulcerative lesions and strictures throughout the gastrointestinal tract, but also effectively achieve epithelialization of injuries to the mucous membrane of the oral cavity, esophagus, stomach, small and large intestine. One of them is Rebamipid-CZ, which has a fairly high safety and efficacy profile. It seems important to consider the issues of optimizing the prevention and treatment of erosive and ulcerative lesions of various parts of the gastrointestinal tract of various etiologies, taking into account the possibility of using rebamipide both as part of complex therapy and in isolation.

Abstract
AbstractWireless capsule endoscopy (WCE) might move through human body and captures the small bowel and captures the video and require the analysis of all frames of video due to which the diagnosis of gastrointestinal infections by the physician is a tedious task. This tiresome assignment has fuelled the researcher’s efforts to present an automated technique for gastrointestinal infections detection. The segmentation of stomach infections is a challenging task because the lesion region having low contrast and irregular shape and size. To handle this challenging task, in this research work a new deep semantic segmentation model is suggested for 3D-segmentation of the different types of stomach infections. In the segmentation model, deep labv3 is employed as a backbone of the ResNet-50 model. The model is trained with ground-masks and accurately performs pixel-wise classification in the testing phase. Similarity among the different types of stomach lesions accurate classification is a difficult task, which is addressed in this reported research by extracting deep features from global input images using a pre-trained ResNet-50 model. Furthermore, the latest advances in the estimation of uncertainty and model interpretability in the classification of different types of stomach infections is presented. The classification results estimate uncertainty related to the vital features in input and show how uncertainty and interpretability might be modeled in ResNet-50 for the classification of the different types of stomach infections. The proposed model achieved up to 90% prediction scores to authenticate the method performance.

Abstract
This review considers the data on Helicobacter pylori (H. pylori), which have been accumulated over 40 years since its description as an etiological factor in gastrointestinal diseases. The majority of modern publications are devoted to the study of the pathogenic properties of the microorganism in the development of chronic gastritis, peptic ulcer disease, and gastric cancer, as well as methods for its eradication. However, in recent years, there have been more and more studies which have suggested that H. pylori has a beneficial, or potentially positive, effect on the human body. The authors have attempted to objectively analyze the information accumulated in the literature on H. pylori. Some studies consider it as one of the recently identified human bacterial pathogens, and special attention is paid to the evidence suggesting that it is probably part of the composition of the human microbiome as a commensal (commensal from French to English is a table companion) or even a symbiont. The presented data discussing the presence or absence of the effect of H. pylori on human health suggest that there is an apparent ambiguity of the problem. The re-assessment of the data available on H. pylori infection is important in order to answer the question of whether it is necessary to create a program of mass H. pylori eradication or to apply a more personalized approach to treating patients with H. pylori-associated gastrointestinal diseases and to perform eradication therapy.

Association between past exposure to fine particulate matter (PM 2.5) and peptic ulcer: A cross-sectional study in eastern China. CHEMOSPHERE 2021; 265:128706.

Abstract
Ambient fine particulate matter (particle diameter < 2.5 μm, or PM2.5) is a major public health concern in China. Exposure to PM2.5 has been associated with a wide range of adverse health outcomes. The current study aimed to estimate the association between exposure to PM2.5 and the risk of peptic ulcer diseases (PUDs). We conducted a hospital-based cross-sectional study of seven major cities in Zhejiang Province, China (combined population > 57 million people), which included a total of 647,092 subjects who underwent gastroscopy examination (86,852 subjects were diagnosed with PUDs) recorded in 13 large hospitals from 2014 to 2018. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the relationship between PM2.5 and PUDs, including duodenal ulcers (DUs) and gastric ulcers (GUs). The overall estimated OR (95% CI) associated with every 10-μg/m3 increase in the 1-month average PM2.5 before the detection of PUDs was 1.050 (95% CI: 1.038, 1.063). The association between PM2.5 concentration and the prevalence of PUDs tended to be attenuated but remained significant when considering different exposure periods (OR = 1.030, 95% CI = 1.018-1.043 for the 3-month moving average; OR = 1.020, 95% CI = 1.005-1.037 for the 6-month moving average). Stronger associations were observed for DUs than GUs. The observed positive association of PM2.5 exposure with PUDs remained significant in the two-pollutant models after adjusting for other air pollutants. Our findings could provide scientific evidence for a more general adverse role of air pollution on PUDs.

Abstract
Intracellular calcium (Ca2+) is a critical cell signaling component in gastrointestinal (GI) physiology. Cytosolic calcium ([Ca2+]cyt), as a secondary messenger, controls GI epithelial fluid and ion transport, mucus and neuropeptide secretion, as well as synaptic transmission and motility. The key roles of Ca2+ signaling in other types of secretory cell (including those in the airways and salivary glands) are well known. However, its action in GI epithelial secretion and the underlying molecular mechanisms have remained to be fully elucidated. The present review focused on the role of [Ca2+]cyt in GI epithelial anion secretion. Ca2+ signaling regulates the activities of ion channels and transporters involved in GI epithelial ion and fluid transport, including Cl- channels, Ca2+-activated K+ channels, cystic fibrosis (CF) transmembrane conductance regulator and anion/HCO3- exchangers. Previous studies by the current researchers have focused on this field over several years, providing solid evidence that Ca2+ signaling has an important role in the regulation of GI epithelial anion secretion and uncovering underlying molecular mechanisms. The present review is largely based on previous studies by the current researchers and provides an overview of the currently known molecular mechanisms of GI epithelial anion secretion with an emphasis on Ca2+-mediated ion secretion and its dysregulation in GI disorders. In addition, previous studies by the current researchers demonstrated that different regulatory mechanisms are in place for GI epithelial HCO3- and Cl- secretion. An increased understanding of the roles of Ca2+ signaling and its targets in GI anion secretion may lead to the development of novel strategies to inhibit GI diseases, including the enhancement of fluid secretion in CF and protection of the GI mucosa in ulcer diseases.

Abstract
Background While Helicobacter pylori (H. pylori) ulcers has declined recently, H. pylori-negative and/or gastrotoxic drug-negative peptic ulcers (HNGN-PU) has increased. This study aimed to analyze the etiology of peptic ulcers in children and the differences in clinical, laboratory, endoscopic, and histopathologic findings of peptic ulcers according to etiology, including eosinophilic gastroenteritis (EoGE). Methods In total, 255 children (157 boys and 98 girls) with peptic ulcers were recruited. The subjects were categorized into 5 groups according to the etiology of the ulcer: 1) H. pylori infection (n = 51); 2) gastrotoxic drugs (n = 18); 3) idiopathic (n = 144); 4) systemic disease (n = 23); 5) EoGE (n = 19). Clinical data were reviewed and analyzed retrospectively. Results Age at diagnosis, ulcer recurrence, atopic dermatitis history, white blood cell count, blood eosinophil count, platelet count, serum albumin level, iron level, erythrocyte sedimentation rate, and C-reactive protein level differed significantly among the 5 groups (all p < 0.05). Regarding endoscopic findings, multiple ulcers and gastric mucosal nodularity differed among the 5 groups (all p < 0.05). When comparing the EoGE ulcer group with the others, EoGE group revealed older ages (p = 0.022), higher rates of ulcer recurrence (p = 0.018), atopic dermatitis history (p = 0.001), and both blood and tissue eosinophilia (both p = 0.001). Conclusions EoGE ulcers constituted 10.2% of HNGN-PU in pediatric patients. In children with HNGN-PU, peripheral eosinophilia, ulcer recurrence, and atopic dermatitis history might imply EoGE, necessitating thorough investigation of tissue eosinophils during endoscopic biopsy. Trial registration A total of 255 children was retrospectively registered between between July 2003 and April 2017.

World J Gastroenterol 2019; 25:6342-6353. [PMID: 31754294 PMCID: PMC6861850 DOI: 10.3748/wjg.v25.i42.6342] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2019] [Revised: 09/11/2019] [Accepted: 11/01/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The two main causes of gastric ulcer bleeding are Helicobacter pylori (H. pylori) infection and ulcerogenic medicines, although the number of cases caused by each may vary with age. In Japan, the rate of H. pylori infection has fallen over the last decade and the number of prescriptions for non-steroidal anti-inflammatory drugs (NSAIDs) and antithrombotic drugs is increasing as the population ages. Methods of treatment for gastric ulcer bleeding have advanced with the advent of hemostatic forceps and potassium-competitive acid blocker (P-CAB). Thus, causes and treatments for gastric ulcer bleeding have changed over the last decade.
AIM To examine the trends of gastric ulcer bleeding over 10 years in the metropolitan area of Japan.
METHODS This is a single-center retrospective study. A total of 564 patients were enrolled from inpatients admitted to our hospital with gastric ulcer bleeding between 2006 and 2016. Age, medication history, H. pylori infection, method of treatment, rate of rebleeding, and the length of hospitalization were analyzed. Factors associated with gastric ulcer bleeding were evaluated using Fisher’s exact test, Pearson’s Chi-squared test or Student’s t-test as appropriate. The Jonckheere-Terpstra test was used to evaluate trends. A per-protocol analysis was used to examine the rate of H. pylori infection.
RESULTS There was a significant increase in the mean age over time (P < 0.01). The rate of H. pylori infection tended to decrease over the study period (P = 0.10), whereas the proportion of patients taking antithrombotic agents or NSAIDs tended to increase (P = 0.07). Over time, the use of NSAIDs and antithrombotic drugs increased with age. By contrast, the rate of H. pylori infection during the study period fell with age. H. pylori-induced ulcers accounted for the majority of cases in younger patients (< 70 years old); however, the rate decreased with age (P < 0.01). The method of treatment trend has changed significantly over time. The main method of endoscopic hemostasis has changed from clipping and injection to forceps coagulation (P < 0.01), and frequently prescribed medicines have changed from proton pump inhibitor to P-CAB (P < 0.01). The rate of rebleeding during the latter half of the study was significantly lower than that in the first half.
CONCLUSION These trends, gastric ulcers caused by ulcerogenic drugs were increasing with age and H. pylori-induced ulcers were more common in younger patients, were observed.

Abstract
Objectives: Peptic ulcer disease (PUD) is still common worldwide and is characterized by high mortality and morbidity. Following the decline of Helicobacter pylori infection, the detection of idiopathic PUD (IPUD) has become more frequent, making diagnosis and treatment more difficult. In this study, the clinical features and natural history of IPUD were analyzed.Methods: This was a retrospective case‒control study conducted in a tertiary care setting (University of Sassari, Italy). Records of 9,212 patients undergoing upper endoscopy from 2002 to 2018 were analyzed. Following the exclusion of H. pylori, NSAIDs, and unusual PUD causes, the remaining were labelled as IPUD. Cases (IPUD) and controls (PUD negative) were compared, adjusting for several covariates through multivariate logistic regression models.Results: Among 380 PUD, 95 were considered IPUD. The proportion rose over the study period in contrast to the decline of H. pylori-PUD. Factors significantly associated with IPUD, after adjusting for all covariates, were age (OR, 3.520; 95% CI, 1.634 - 7.585), male sex (OR, 3.126; 95% CI, 1.888 - 5.176), hospitalization (OR, 2.968; 95% CI, 1.926 - 4.575), and number of medications (OR, 2.808; 95% CI, 1.178 - 6.735). A clinical history positive for PUD was the major risk associated with IPUD (OR, 3.729; 95% CI, 2.050 - 6.785). Patients with IPUD were treated with the highest proton pump inhibitor (PPI) dose for 40-60 days. Follow up endoscopy showed a cure rate of 97.6%.Conclusion: The relative proportion of IPUD is increasing in our population in contrast to the drop of H. pylori-PUD. Treatment with high-dose PPI, and for a long duration, heals IPUD and protects from recurrence.

Is the new potent acid-inhibitory drug vonoprazan effective for healing idiopathic peptic ulcers? A multicenter observational study in Akita Prefecture, Japan. J Gastroenterol 2019; 54:963-971.

Abstract
BACKGROUND The incidence of peptic ulcers unrelated to H. pylori infection and non-steroidal anti-inflammatory drugs (NSAIDs), termed idiopathic peptic ulcers (IPUs), has increased worldwide. We recently reported that IPUs were refractory to proton pump inhibitor (PPI) treatment. Vonoprazan, which was recently developed in Japan, has shown a more potent acid-inhibitory effect than ordinary PPIs. In the present study, we compared the healing rates among peptic ulcers of different etiologies following treatment with vonoprazan. METHOD A multicenter observational study was performed at six participating hospitals in Akita Prefecture, Japan. Consecutive patients who had endoscopically confirmed gastro-duodenal ulcers were enrolled between August 2016 and March 2018. For each patient, the Helicobacter pylori infection status and NSAID use, including aspirin, were checked, and 20 mg vonoprazan was administered for 6 weeks for duodenal ulcers and 8 weeks for gastric ulcers. The healing status was checked by endoscopy at the end of vonoprazan treatment. Patients were divided into four subgroups according to the H. pylori status and NSAID usage. RESULTS The proportion of IPUs was 18.2%. A total of 162 patients completed the study protocol. The healing rate of IPUs was marginally lower than that of simple H. pylori-associated ulcers (81.2% vs. 93.5%, P = 0.05). Similarly, the healing rate of NSAID-related ulcers, irrespective of concomitant H. pylori infection, was significantly lower than that of simple H. pylori-associated ulcers. CONCLUSIONS Six- or 8-week vonoprazan treatment still seems to be insufficient for healing IPUs. Longer-term vonoprazan or another treatment option may be required to heal potentially refractory peptic ulcers.

Abstract
BACKGROUND Recent data suggest that in children, the proportion of gastroduodenal ulcers/erosions associated with Helicobacter pylori infection is currently lower than expected. In this study, we trace this proportion over two decades. METHODS We reviewed the reports of all upper gastrointestinal endoscopies with biopsies for histology and culture over the past 23 years. H pylori status was assessed using several invasive methods. The infection rate during different time periods was compared between children with lesions and controls. RESULTS A total of 7849 endoscopies were performed in 5983 children (2874 F/3109 M, median age 7.6 years, range 0.1-17.9 years). The endoscopy report was missing in 316 patients. At the first upper gastrointestinal endoscopy, 12.1% of the children presented with gastric and/or duodenal ulcers or erosions with an H pylori infection rate of 35.4%, whereas no such lesions were observed in 87.9% of children in whom the H pylori infection rate was 21.3%. The risk factors associated with such lesions were older age (P < 0.001), male sex (P = 0.002), and H pylori infection (P < 0.0001). Gastric ulcers were not significantly associated with H pylori (24% infected), whereas 52% of duodenal ulcers, 33% of gastric erosions, and 38% of duodenal erosions were associated with H pylori. The proportion of gastroduodenal lesions associated with H pylori remained stable over time. Children with H pylori infection and ulcers were older than those with H pylori infection without ulcers (P < 0.001). CONCLUSIONS Our study indicates that in our pediatric population, the proportion of ulcers without H pylori infection is higher than previously suggested, and this prevalence has not changed over the past two decades.

Abstract
BACKGROUND After the discovery of Helicobacter pylori (H. pylori) in the last century, more than 90% of people with peptic ulcer were found to be infected with H. pylori. However, epidemiological studies in recent years have shown that H. pylori is not so closely related to peptic ulcer. More and more H. pylori negative gastric ulcers have been found around the world, and in recent years they have been increasing year by year. This may be related to the extensive application of H. pylori eradication therapy in recent years and the resulting decrease of H. pylori infection rate. H. pylori negative gastric ulcer and H. pylori positive ulcer may have independent pathophysiological mechanisms.
AIM To investigate the efficacy of esomeprazole combined with Kangfuxin in the treatment of H. pylori negative gastric ulcer and the influence on inflammatory factors.
METHODS One hundred and twenty-eight patients with gastric ulcer treated at our hospital from May 2017 to May 2018 were randomly divided into an observation group and a control group. The control group was treated with esomeprazole and the observation group was treated with esomeprazole combined with Kangfuxin. The clinical efficacy of the two groups was evaluated and the levels of interleukin (IL)-1β and IL-6 were measured. The levels of tumor necrosis factor (TNF)-α, interferon (IFN)-γ, and C-reactive protein (CRP), clinical symptom scores, adverse reactions, and recurrence were also recorded.
RESULTS Compared with the values before treatment, the scores of clinical symptoms and total clinical symptoms in the two groups decreased significantly after treatment (P < 0.05). After treatment, the scores of clinical symptoms and total clinical symptoms in the observation group decreased more significantly compared with the control group (P < 0.05). After treatment, the levels of IL-1β, IL-6, TNF-α, IFN-γ, and CRP decreased significantly in both groups compared with the values before treatment (P < 0.05). In the observation group, the scores of IL-1β, IL-6, TNF-α, and IFN-γ decreased more significantly than those in the control group (P < 0.05). The total effective rate in the observation group (93.75%) was significantly higher than that of the control group (73.44%), although there was no significant difference in adverse reactions or ulcer recurrence between the two groups (P > 0.05).
CONCLUSION Esomeprazole combined with Kangfuxin is effective in the treatment of H. pylori negative gastric ulcer and can significantly reduce the level of inflammatory factors, reduce the body's immune response, promote the early healing of ulcer, and improve the prognosis of patients.

Abstract
Very few studies have been performed to determine whether there is a relationship between air pollution and increases in hospitalizations for peptic ulcer, and for those that have occurred, their results may not be completely relevant to Taiwan, where the mixture of ambient air pollutants differ. We performed a time-stratified case-crossover study to investigate the possible association between air pollutant levels and hospital admissions for peptic ulcer in Taipei, Taiwan. To do this, we collected air pollution data from Taiwan's Environmental Protection Agency and hospital admissions for peptic ulcer data for the years 2009-2013 from Taiwan's National Health Insurance's research database. We used conditional logistic regression to analyze the possible association between the two, taking temperature and relative humidity into account. Risk was expressed as odds ratios and significance was expressed with 95% confidence intervals. In our single pollutant model, peptic ulcer admissions were significantly associated with all pollutants (PM10, PM2.5, SO2, NO2, CO, and O3) on warm days (>23 °C). On cool days (<23 °C), peptic ulcer admissions were significantly associated with PM10, NO2, and O3. In our two-pollutant models, peptic ulcer admissions were significantly associated NO2 and O3 when combined with each of the other pollutants on warm days, and with PM10, NO2, and O3 on cool days. It was concluded that the likelihood of peptic ulcer hospitalizations in Taipei rose significantly with increases in air pollutants during the study period.

Abstract
Background Helicobacter pylori (HP) infection is one of the hypothesized infectious etiologies of gastric cancer (GC) and other gastroduodenal diseases. It was suggested that other infectious agents, including oncogenic viruses, may increase the risk of gastroduodenal diseases. A number of reports regarding JC polyomavirus (JCPyV) have shown that JCPyV could be implicated in colorectal cancer and gastrointestinal carcinogenesis. Objective The current investigation aimed to investigate whether JCPyV could have any association with the pathogenesis of gastroduodenal diseases either alone or together with HP. Methods A total of 237 fresh or formalin-fixed and paraffin-embedded gastroduodenal samples were examined by quantitative real-time polymerase chain reaction targeting the JCPyV large tumor antigen (LTag) oncogene, and viral load was determined as viral copy number/cell. Results In total, 2 out of 237 samples (0.8%) were positive for JCPyV LTag DNA. One positive sample derived from diffuse-type gastric adenocarcinoma (6.8 × 10-3 copies/cell) and other JCPyV-positive sample obtained from a patient with gastritis (2.5 × 10-3 copies/cell) were recorded. Both JCPyV-positive samples were negative for HP infection. Conclusion This study suggests no association between JCPyV infection and GC or other gastroduodenal diseases. The very low frequency of JCPyV LTag sequences in GC is an important aspect that weakens the hypothesis of the pathogenic role of JCPyV in gastric tumor induction.

Abstract
Non-variceal upper gastrointestinal bleeding (NVUGIB) is bleeding that develops in the oesophagus, stomach or proximal duodenum. Peptic ulcers, caused by Helicobacter pylori infection or use of NSAIDs and low-dose aspirin (LDA), are the most common cause. Although the incidence and mortality associated with NVUGIB have been decreasing owing to considerable advances in the prevention and management of NVUGIB over the past 20 years, it remains a common clinical problem with an annual incidence of ∼67 per 100,000 individuals in the United States in 2012. NVUGIB is a medical emergency, and mortality is in the range ∼1-5%. After resuscitation and initial assessment, early (within 24 hours) diagnostic and therapeutic endoscopy together with intragastric pH control with proton pump inhibitors (PPIs) form the basis of treatment. With a growing ageing population treated with antiplatelet and/or anticoagulant medications, the clinical management of NVUGIB is complex as the risk between gastrointestinal bleeding events and adverse cardiovascular events needs to be balanced. The best clinical approach includes identification of risk factors and prevention of bleeding; available strategies include continuous treatment with PPIs or H. pylori eradication in those at increased risk of developing NVUGIB. Treatment with PPIs and/or use of cyclooxygenase-2-selective NSAIDs should be implemented in those patients at risk of NVUGIB who need NSAIDs and/or LDA.

Abstract
Herein, we describe a rare case of refractory gastric antral ulcers. A woman in her 50 s was admitted to Nagoya City University Hospital with epigastric pain after being diagnosed with gastric antral submucosal tumor at another hospital. Findings from esophagogastroduodenoscopy and endoscopic ultrasound examination revealed that the lesion was a gastric ulcer. The patient had no Helicobacter pylori infection and no recent history of using non-steroidal anti-inflammatory drugs. On the basis of these findings, we diagnosed this as a case of refractory gastric antral ulcer (RGAU). RGAU is considered a new disease concept and detailed analyses are expected in the future.

Cell Mol Gastroenterol Hepatol 2018; 6:199-213.

Abstract
BACKGROUND & AIMS Aging gastric mucosa has increased susceptibility to injury and delayed healing owing to impaired angiogenesis, but the mechanisms are not fully known. We examined whether impairment of angiogenesis in aging gastric mucosa is caused by deficiency of nerve growth factor (NGF) in gastric endothelial cells (ECs), and whether NGF therapy could reverse this impairment. METHODS In gastric mucosal ECs (GECs) isolated from young and aging rats we examined the following: (1) in vitro angiogenesis, (2) NGF expression, and (3) the effect of NGF treatment on angiogenesis, GEC proliferation and migration, and dependence on serum response factor. In in vivo studies in young and aging rats, we examined NGF expression in gastric mucosa and the effect of NGF treatment on angiogenesis and gastric ulcer healing. To determine human relevance, we examined NGF expression in gastric mucosal biopsy specimens of aging (≥70 y) and young (≤40 y) individuals. RESULTS In cultured aging GECs, NGF expression and angiogenesis were reduced significantly by 3.0-fold and 4.1-fold vs young GECs. NGF therapy reversed impairment of angiogenesis in aging GECs, and serum response factor silencing completely abolished this response. In gastric mucosa of aging rats, NGF expression in GECs was reduced significantly vs young rats. In aging rats, local NGF treatment significantly increased angiogenesis and accelerated gastric ulcer healing. In aging human subjects, NGF expression in ECs of gastric mucosal vessels was 5.5-fold reduced vs young individuals. CONCLUSIONS NGF deficiency in ECs is a key mechanism underlying impaired angiogenesis and delayed ulcer healing in aging gastric mucosa. Local NGF therapy can reverse these impairments.

Abstract
BACKGROUND Aside from Helicobacter pylori, another cause for the development or worsening of gastrointestinal ulcers is scrub typhus, an acute febrile disease caused by Orientia tsutsugamushi. We aimed to compare the endoscopic characteristics of peptic ulcers caused by these infectious agents. METHODS This retrospective case-control study involved patients who underwent upper gastrointestinal endoscopy at Chosun University Hospital in Korea. We compared endoscopic features and demographic characteristics between patients with H. pylori infection and those with O. tsutsugamushi infection. RESULTS A total of 141 patients with peptic ulcer were included in the study. Compared to patients with O. tsutsugamushi infection (n = 62; age, 63.8 ± 12.1 years; male sex, 42%), those with H. pylori infection (n = 79; age, 53.0 ± 14.8 years; male sex, 81%) were younger and more likely to be male (P < .001 for both). Patients with O. tsutsugamushi infection were more likely to have multiple lesions (40/62, 64.5% vs 37/79, 46.8%; P = .042) and irregular-shaped lesions (27/62, 43.6% vs 20/79, 25.3%; P = .031). Patients with H. pylori infection had higher incidence of hemorrhagic ulcers (26/79, 32.9% vs 8/62, 12.9%; P = .007), and lesions occurred most often in the duodenum (43.0%), followed by the antrum (36.7%), body (34.2%), and angle (12.7%) of the stomach. In patients with O. tsutsugamushi infection, lesions occurred most often in the antrum (70.97%), followed by the duodenum (35.5%), body (22.6%), and angle (14.5%) of the stomach. In both groups, gastric ulcer lesions occurred most often in the antrum, followed by the body and angle of the stomach (36.7% vs 70.97%, 34.2% vs 22.6%, and 12.7% vs 14.5% for gastric ulcers associated with H. pylori and O. tsutsugamushi infection, respectively). Patients with O. tsutsugamushi infection had significantly higher incidence of ulcers on the antrum (70.97% vs 36.7%, P < .001) and the greater curvature (45.2% vs 24.0%, P = .012). Finally, 35.5% of patients with gastric ulcer caused by scrub typhus also had duodenal ulcer. CONCLUSION This is the first study to compare endoscopic features of peptic ulcers caused by H. pylori and O. tsutsugamushi. Peptic ulcers in patients with H. pylori infection occurred predominantly in the antrum/body/lesser curvature and presented with single, round/oval lesions, while ulcers in patients with scrub typhus occurred predominantly in the antrum/greater curvature and presented with multiple, irregular lesions. Scrub typhus should be considered as a cause of duodenal ulcer in scrub typhus-endemic areas.

Abstract
OBJECTIVE To examine whether mental vulnerability, an enduring personality characteristic, predicts incident hospital-diagnosed ulcer over three decades. MATERIALS AND METHODS A population-based cohort study enrolled 3365 subjects with no ulcer history, ages 30-60, in 1982-3. Mental vulnerability, Helicobacter pylori IgG antibodies, socioeconomic status, and sleep duration were determined at baseline; non-steroidal antiinflammatory drug use, smoking, leisure time physical activity, and alcohol consumption both at baseline and in 1993-4. Hospital diagnoses of incident ulcer through 2011 were detected using the Danish National Patient Registry. RESULTS Ulcers were diagnosed in 166 subjects, including 83 complicated by bleeding or perforation. Age-, gender-, and socioeconomic status-adjusted associations were significant for mental vulnerability (Hazard Ratio (HR) 2.0, 95% Confidence Interval 1.4-2.8), Helicobacter pylori (HR 1.7, CI 1.2-2.3), smoking (HR 2.0, CI 1.3-3.1), heavy drinking (HR 1.6, CI 1.1-2.4), abstinence (HR 1.6, CI 1.1-2.5), non-steroidal antiinflammatory drugs (HR 2.1, CI 1.5-3.0), and sedentary lifestyle (HR 1.9, CI 1.4-2.7). Adjusted for all behavioral mediators, the HR for mental vulnerability was 1.5 (CI 1.0-2.2, p = .04). Mental vulnerability raised risk in Helicobacter pylori seropositive subjects and those exposed to neither Helicobacter pylori nor non-steroidal antiinflammatory drugs; its impact was virtually unchanged when analysis was limited to complicated ulcers. CONCLUSIONS A vulnerable personality raises risk for hospital-diagnosed peptic ulcer, in part because of an association with health risk behaviors. Its impact is seen in 'idiopathic' and Helicobacter pylori-associated ulcers, and in acute surgical cases.

Abstract
BACKGROUND Atrial fibrillation (AF) increases the risk of thromboembolic stroke. An oral anticoagulant should be administrated to prevent stroke in patients with moderate stroke risk (ie, CHA2DS2-VASc score>2). If the stroke risk is low (i.e. the score=1), however, antiplatelet agent such as aspirin is widely used. Aspirin can cause peptic ulcer disease (PUD) while its alternative, clopidogrel, theoretically does not. OBJECTIVE To elucidate the efficacy and safety between aspirin and clopidogrel, a multicenter randomized controlled trial was designed in AF patients with low stroke risk. METHODS According to sample size estimation based on previous literature, a total of 1560 AF patients with low stroke risk will be randomly assigned into 4 different groups dependent upon initial esophagogastroduodenoscopy (EGD) results: two mono-antiplatelet treatment groups with either aspirin 100mg or clopidogrel 75mg for 1year; two antiplatelet agent and proton pump inhibitor (PPI) combination groups. Follow-up EGD will be performed at 1year. RESULTS The clinical follow-up will be performed for 1year after enrollment. The primary efficacy endpoint is to compare the annual stroke rate between aspirin and clopidogrel treatment groups. The primary safety endpoint is to compare the prevalence of drug-induced gastrointestinal (GI) and intracranial hemorrhage and upper-GI response including PUD based on EGD after 1year. CONCLUSIONS This trial will determine whether clopidogrel is noninferior in stroke prevention and superior in reduction of GI events including PUD to aspirin in AF patients with low stroke risk.

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

Abstract
The serum pepsinogen (PG) assay findings are correlated with the status of Helicobacter pylori infection, but there are controversies on the link with upper gastrointestinal (UGI) endoscopic findings. The aim of this study was to determine the significance of a serum PG assay for correlating with endoscopic findings in H. pylori-seroprevalent adult population. Korean adults who visited for a health check-up were included consecutively. Subjects after gastrectomy or H. pylori eradication were excluded. After completing the serum PG assay and anti-H. pylori immunoglobulin G (IgG) titer on the same day of UGI endoscopy, subjects with equivocal serology test finding or gastric neoplasm were excluded. Of the 4,830 included subjects, 3,116 (64.5%) were seropositive for H. pylori. Seropositive finding was related to high serum PG I (P < 0.001) and PG II (P < 0.001) concentrations, low PG I/II ratio (P < 0.001), old age (P < 0.001), and male gender (P = 0.006). After adjusting age and gender, the serum PG I and II concentrations were positively correlated with the presence of nodular gastritis (NG) (all P = 0.003). The serum PG I was positively correlated with gastric ulcer (P = 0.003), and it was correlated with duodenal ulcer in seropositive subjects (P = 0.008). The PG I/II ratio was positively correlated with erosive esophagitis, while it was inversely related to chronic atrophic gastritis and metaplastic gastritis (all P < 0.001). Our findings suggest that the serum PG assay finding correlates well with the UGI endoscopic finding. A higher serum PG concentration in subjects with NG and peptic ulcer disease suggests that endoscopic findings reflect gastric secreting ability.

Abstract
AIM To assess the prevalence of possible risk factors of upper gastrointestinal bleeding (UGIB) and their age-group specific trend among the general population and osteoarthritis patients.
METHODS We utilized data from the National Health Insurance Service that included claims data and results of the national health check-up program. Comorbid conditions (peptic ulcer, diabetes, liver disease, chronic renal failure, and gastroesophageal reflux disease), concomitant drugs (aspirin, clopidogrel, cilostazol, non-steroidal anti-inflammatory drugs, steroid, anticoagulants, and SSRI), personal habits (smoking, and alcohol consumption) were considered as possible UGIB risk factors. We randomly imputed the prevalence of infection in the data considering the age-specific prevalence of Helicobacter pylori (H. pylori) infection in Korea. The prevalence of various UGIB risk factors and the age-group specific trend of the prevalence were identified. Prevalence was compared between osteoarthritis patients and others.
RESULTS A total of 801926 subjects (93855 osteoarthritis patients) aged 20 and above were included. The prevalence of individual and concurrent multiple risk factors became higher as the age increased. The prevalence of each comorbid condition and concomitant drug were higher in osteoarthritis patients. Thirty-five point zero two percent of the overall population and 68.50% of osteoarthritis patients had at least one or more risk factors of UGIB. The prevalence of individual and concurrent multiple risk factors in younger age groups were also substantial. Furthermore, when personal habits (smoking, and alcohol consumption) and H. pylori infection were included, the prevalence of concurrent multiple risk factors increased greatly even in younger age groups.
CONCLUSION Prevalence of UGIB risk factors was high in elderly population, but was also considerable in younger population. Patient with osteoarthritis was at higher UGIB risk than those without osteoarthritis. Physicians should consider individualized risk assessment regardless of age when prescribing drugs or performing procedures that may increase the risk of UGIB, and take necessary measures to reduce modifiable risk factors such as H. pylori eradication or lifestyle counseling.

Abstract
BACKGROUND AND AIM Helicobacter pylori-negative and non-steroidal anti-inflammatory drugs (NSAIDs)-negative idiopathic peptic ulcers (IPU) have attracted attention in Japan and other developed countries. The aim of the present study was to clarify the healing rate of IPU and the risk of recurrence. METHODS We conducted a retrospective follow-up study of patients with peptic ulcer disease (PUD) who were diagnosed in our previous multicenter-prospective study. Three hundred and eighty-two patients from four institutions in the Tohoku district were enrolled. Enrolled subjects were divided into four groups according to H. pylori infection and intake of NSAIDs. In these patients, we checked treatment course, healing rate during 3 months, and recurrence rate. RESULTS Healing rates in the: (i) simple H. pylori group; (ii) H. pylori (+)/ NSAIDs (+) group, (iii) simple NSAIDs group; and (iv) IPU group, were 95.0%, 94.9%, 73.3%, and 77.4%, respectively. The healing rate of the IPU group was significantly lower than that of both the simple H. pylori group and the H. pylori (+)/ NSAIDs (+) group (P < 0.01). The recurrence rate of 13.9% in the IPU group was much higher than the 2.1% in the simple H. pylori group (P < 0.01). Additionally, the cumulative recurrence rates by the Kaplan-Meier method in the IPU group were significantly higher than those of the simple H. pylori group (P = 0.015). CONCLUSION We demonstrated that the clinical course of peptic ulcers is considerably different depending on the cause. IPU could be refractory to treatment and prone to recur compared with simple H. pylori ulcers.

Abstract
OBJECTIVE Helicobacter pylori infection-negative, nonsteroidal antiinflammatory drugs (NSAIDs)-negative peptic ulcers, which are termed idiopathic peptic ulcers (IPUs), have been increasing worldwide. In this study, we investigated the preferential locations of gastric ulcers according to their cause (e.g., H. pylori and NSAIDs), with special attention to IPUs. MATERIAL AND METHODS A total of 361 patients consecutively diagnosed with a peptic ulcer over a period of one year were classified into four groups according to H. pylori-infection status and NSAIDs usage. The ulcer location was divided into the antrum, angularis, and body, and was compared among the four ulcer groups. RESULTS The ulcers of 43 patients were classified as IPUs. Compared with simple H. pylori ulcers, IPUs more preferentially located in the antrum (14% vs. 52%, p < 0.01). The difference was more pronounced in the analysis of IPUs in which patients with a history of H. pylori eradication or those with severe atrophic gastritis were excluded, and 79% of these IPUs were located in the antrum. With duodenal ulcers taken together, the vast majority of (86%) these IPUs occurred in the duodenal bulb or the antrum. The proportion of antral ulcers in NSAISs users also differed depending on the presence of concomitant H. pylori infection (positive: 22% vs. negative: 62%, p < 0.01). CONCLUSION There was a striking difference in the ulcer location within the stomach depending on the cause of the ulcer, and IPUs predominantly occurred in the antrum. This information on the preferential locations of ulceration should provide endoscopists with some hints concerning the etiology of ulcers.

Abstract
Little is known about the effect of air pollution on the gastrointestinal (GI) system. We investigated the association between long-term exposures to outdoor fine particles (PM2.5) and hospitalization for peptic ulcer diseases (PUDs) in a large cohort of Hong Kong Chinese elderly.A total of 66,820 subjects aged ≥65 years who were enrolled in all 18 Government Elderly Health Service centers of Hong Kong participated in the study voluntarily between 1998 and 2001. They were prospectively followed up for more than 10 years. Annual mean exposures to PM2.5 at residence of individuals were estimated by satellite data through linkage with address details including floor level. All hospital admission records of the subjects up to December 31, 2010 were retrieved from the central database of Hospital Authority. We used Cox regression to estimate the hazard ratio (HR) for PUD hospitalization associated with PM2.5 exposure after adjustment for individual and ecological covariates.A total of 60,273 subjects had completed baseline information including medical, socio-demographic, lifestyle, and anthropometric data at recruitment. During the follow-up period, 1991 (3.3%) subjects had been hospitalized for PUD. The adjusted HR for PUD hospitalization per 10 μg/m of PM2.5 was 1.18 (95% confidence interval: 1.02-1.36, P = 0.02). Further analysis showed that the associations with PM2.5 were significant for gastric ulcers (HR 1.29; 1.09-1.53, P = 0.003) but not for duodenal ulcers (HR 0.98; 0.78 to 1.22, P = 0.81).Long-term exposures to PM2.5 were associated with PUD hospitalization in elder population. The mechanism underlying the PM2.5 in the development of gastric ulcers warrants further research.

Abstract
BACKGROUND Although Helicobacter pylori and non-steroidal anti-inflammatory drugs (NSAIDs) are the main causes of peptic ulcers disease (PUD), recently the prevalence of idiopathic peptic ulcer (IPU) is increasing in most parts of the world. The aim of this study was to assess the prevalence of IPU in Kerman, the center of largest province in south-east Iran. METHODS We included 215 patients with peptic ulcer in our study. Combined methods rapid urease test (RUT), histology, and real time polymerase chain reaction (PCR) was performed on endoscopic samples of peptic ulcers. NSAID use was determined by medical history. SPSS software version 16 was used for data analysis. p value<0.05 was considered as statistically significant. RESULTS Of 215 consecutive patients with peptic ulcer, four (1.8%) had H.pylorinegative and NSAID-negative PUD. There were not significant differences between patients with IPU and patients with peptic ulcer associated with H.pylori or NSAIDs regarding the sex, age, cigarette smoking, and opioid abuse. CONCLUSION Our study showed that in contrast to other reports from western and some Asian countries, the prevalence of IPU is low in Kerman and H.pylori infection is still the major cause of PUD. We recommend a large and multi-central study to determine the prevalence of IPU in Iran.

Abstract
AIM: To investigate the clinical characteristics and outcomes of idiopathic Helicobacter pylori (H. pylori)-negative and drug-negative] peptic ulcer bleeding (PUB).
METHODS: A consecutive series of patients who experienced PUB between 2006 and 2012 was retrospectively analyzed. A total of 232 patients were enrolled in this study. The patients were divided into four groups according to the etiologies of PUB: idiopathic, H. pylori-associated, drug-induced and combined (H. pylori-associated and drug-induced) types. We compared the clinical characteristics and outcomes between the groups. When the silver stain or rapid urease tests were H. pylori-negative, we obtained an additional biopsy specimen by endoscopic re-examination and performed an H. pylori antibody test 6-8 wk after the initial endoscopic examination. For a diagnosis of idiopathic PUB, a negative result of an H. pylori antibody test was confirmed. In all cases, re-bleeding was confirmed by endoscopic examination. For the risk assessment, the Blatchford and the Rockall scores were calculated for all patients.
RESULTS: For PUB, the frequency of H. pylori infection was 59.5% (138/232), whereas the frequency of idiopathic cases was 8.6% (20/232). When idiopathic PUB was compared to H. pylori-associated PUB, the idiopathic PUB group showed a higher rate of re-bleeding after initial hemostasis during the hospital stay (30% vs 7.4%, P = 0.02). When idiopathic PUB was compared to drug-induced PUB, the patients in the idiopathic PUB group showed a higher rate of re-bleeding after initial hemostasis upon admission (30% vs 2.7%, P < 0.01). When drug-induced PUB was compared to H. pylori-associated PUB, the patients in the drug-induced PUB were older (68.49 ± 14.76 years vs 47.83 ± 15.15 years, P < 0.01) and showed a higher proportion of gastric ulcer (77% vs 49%, P < 0.01). However, the Blatchford and the Rockall scores were not significantly different between the two groups. Among the patients who experienced drug-induced PUB, no significant differences were found with respect to clinical characteristics, irrespective of H. pylori infection.
CONCLUSION: Idiopathic PUB has unique clinical characteristics such as re-bleeding after initial hemostasis upon admission. Therefore, these patients need to undergo close surveillance upon admission.

Abstract
Background. Helicobacter pylori (HP) infection and nonsteroidal anti-inflammatory drugs (NSAID) use are considered the main risk to develop peptic ulcer disease (PUD). However, PUD also occurs in the absence of HP infection and/or NSAID use. Recently, we have found evidence that Epstein-Barr virus (EBV) reactivation increases the risk to develop premalignant and malignant gastric lesions. Objective. To study a possible association between EBV and PUD. Methods. Antibodies against an EBV reactivation antigen, HP, and the HP virulence factor CagA were measured in sera from 207 Mexican subjects, controls (healthy individuals, n = 129), and PUD patients (n = 78, 58 duodenal and 20 gastric ulcers). Statistical associations were estimated. Results. Duodenal PUD was significantly associated with high anti-EBV IgG titers (p = 0.022, OR = 2.5), while anti-EBV IgA was positively associated with gastric PUD (p = 0.002, OR = 10.1). Conclusions. Our study suggests that EBV reactivation in gastric and duodenal epithelium increases the risk to develop PUD.

Abstract
BACKGROUND AND AIM The prevalence of Helicobacter pylori-negative and nonsteroidal anti-inflammatory drug-negative peptic ulcers, commonly known as idiopathic peptic ulcers (IPUs), has been reported to be very low (0.9-2.6%) in Japan based on data from the 1990s. However, recent trends have yet to be been reported. Herein, we present a multicenter prospective analysis between 2012 and 2013 investigating current trends in the prevalence and characteristics of IPUs in Japan. METHODS Clinical data of all peptic ulcer subjects detected via endoscopy at four participating hospitals were prospectively collected between April 2012 and March 2013. Enrolled subjects were classified according to H. pylori infection status and intake of nonsteroidal anti-inflammatory drugs. Multiple logistic regression analyses were used to determine the risk factors for IPUs. RESULTS Of 382 enrolled patients with peptic ulcers, 46 (12%) were judged to have IPUs. Compared with those with simple H. pylori-positive ulcers, patients with IPUs were significantly older (P < 0.02) and more often had underlying comorbidities such as hypertension (P < 0.02) and hyperlipidemia (P < 0.05). Multivariate regression analysis indicated that the presence of multiple underlying diseases was the only significant risk factor for IPUs, with an odds ratio of 3.8 (95% confidence interval, 1.3-11.1). CONCLUSIONS This study revealed that the prevalence of IPUs in patients with peptic ulcers in Japan is 12%, much higher than previously reported. Presence of multiple underlying comorbid diseases, rather than aging itself, is an important risk factor for IPUs.

Abstract
Helicobacter pylori (H pylori) infection is one of the most common chronic bacterial infections worldwide. International guidelines recommend H pylori eradication in several scenarios: patients with peptic ulcer disease, patients who have had endoscopic resection of early gastric cancer, and patients with a gastric mucosa-associated lymphoid tissue lymphoma (MALToma). There is variability among the guidelines for other conditions. Treatment options for H pylori infection include triple, quadruple, and sequential therapy. Ideally, patients in whom previous eradication attempts failed and those suspected to have resistant strains should be considered for antimicrobial sensitivity testing, which requires culture of gastric mucosal biopsies; such testing, however, has limited availability in the United States. Resistance rates vary by location depending on local antibiotic usage rates. As such, the success rates associated with different regimens vary throughout the world. Many patients with H pylori infection are asymptomatic, whereas others are diagnosed with the infection during evaluation of dyspeptic symptoms or following a diagnosis of peptic ulcer. Symptoms may not be an accurate indicator of treatment success. The American College of Gastroenterology (ACG) endorses the carbon 13-labeled urea breath test ((13)C-UBT) as the most reliable test to confirm H pylori eradication. This clinical roundtable monograph begins with an overview of H pylori infection and then discusses treatment, antibiotic resistance, management of patients with antibiotic resistance, and posttreatment testing, with a focus on the ACG guidelines.
