A population-based study of familial coaggregation and shared genetic etiology of psychiatric and gastrointestinal disorders. COMMUNICATIONS MEDICINE 2024; 4:180. [PMID: 39300237 DOI: 10.1038/s43856-024-00607-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2024] [Accepted: 09/05/2024] [Indexed: 09/22/2024] Open
Abstract
BACKGROUND It has been proposed that having a psychiatric disorder could increase the risk of developing a gastrointestinal disorder, and vice versa. The role of familial coaggregation and shared genetic loading between psychiatric and gastrointestinal disorders remains unclear. METHODS This study used the Taiwan National Health Insurance Research Database; 4,504,612 individuals born 1970-1999 with parental information, 51,664 same-sex twins, and 3,322,959 persons with full-sibling(s) were enrolled. Genotyping was available for 106,796 unrelated participants from the Taiwan Biobank. A logistic regression model was used to examine the associations of individual history, affected relatives, and polygenic risk scores (PRS) for schizophrenia (SCZ), bipolar disorder (BPD), major depressive disorder (MDD), and obsessive-compulsive disorder (OCD), with the risk of peptic ulcer disease (PUD), gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), and inflammatory bowel disease (IBD), and vice versa. RESULTS Here we show that parental psychiatric disorders are associated with gastrointestinal disorders. Full-siblings of psychiatric cases have an increased risk of gastrointestinal disorders except for SCZ/BPD and IBD; the magnitude of coaggregation is higher in same-sex twins than in full-siblings. The results of bidirectional analyses mostly remain unchanged. PRS for SCZ, MDD, and OCD are associated with IBS, PUD/GERD/IBS/IBD, and PUD/GERD/IBS, respectively. PRS for PUD, GERD, IBS, and IBD are associated with MDD, BPD/MDD, SCZ/BPD/MDD, and BPD, respectively. CONCLUSIONS There is familial coaggregation and shared genetic etiology between psychiatric and gastrointestinal comorbidity. Individuals with psychiatric disorder-affected relatives or with higher genetic risk for psychiatric disorders should be monitored for gastrointestinal disorders, and vice versa.

Abstract
Annual prevalence estimates of peptic ulcer disease range between 0·12% and 1·5%. Peptic ulcer disease is usually attributable to Helicobacter pylori infection, intake of some medications (such as aspirin and non-steroidal anti-inflammatory medications), or being critically ill (stress-related), or it can be idiopathic. The clinical presentation is usually uncomplicated, with peptic ulcer disease management based on eradicating H pylori if present, the use of acid-suppressing medications-most often proton pump inhibitors (PPIs)-or addressing complications, such as with early endoscopy and high-dose PPIs for peptic ulcer bleeding. Special considerations apply to patients on antiplatelet and antithrombotic agents. H pylori treatment has evolved, with the choice of regimen dictated by local antibiotic resistance patterns. Indications for primary and secondary prophylaxis vary across societies; most suggest PPIs for patients at highest risk of developing a peptic ulcer, its complications, or its recurrence. Additional research areas include the use of potassium-competitive acid blockers and H pylori vaccination; the optimal approach for patients at risk of stress ulcer bleeding requires more robust determinations of optimal patient selection and treatment selection, if any. Appropriate continuation of PPI use outweighs most possible side-effects if given for approved indications, while de-prescribing should be trialled when a definitive indication is no longer present.

Abstract
Peptic ulcer disease (PUD) is one of the most prevalent gastro intestinal disorder which often leads to painful sores in the stomach lining and intestinal bleeding. Untreated Helicobacter pylori (H. pylori) infection is one of the major reasons for chronic PUD which, if left untreated, may also result in gastric cancer. Treatment of H. pylori is always a challenge to the treating doctor because of the poor bioavailability of the drug at the inner layers of gastric mucosa where the bacteria resides. This results in ineffective therapy and antibiotic resistance. Current treatment regimens available for gastric ulcer and H. pylori infection uses a combination of multiple antimicrobial agents, proton pump inhibitors (PPIs), H2-receptor antagonists, dual therapy, triple therapy, quadruple therapy and sequential therapy. This polypharmacy approach leads to patient noncompliance during long term therapy. Management of H. pylori induced gastric ulcer is a burning issue that necessitates alternative treatment options. Novel formulation strategies such as extended-release gastro retentive drug delivery systems (GRDDS) and nanoformulations have the potential to overcome the current bioavailability challenges. This review discusses the current status of H. pylori treatment, their limitations and the formulation strategies to overcome these shortcomings. Authors propose here an innovative strategy to improve the H. pylori eradication efficiency.

Abstract
Background Clarithromycin-based therapy is important for Helicobacter pylori eradication treatment. However, clarithromycin may increase cardiovascular risk. Hence, we investigated the association between clarithromycin use and outcomes in adults with stable coronary heart disease (CHD) and subsequent peptic ulcer disease (PUD).
Methods This nationwide cohort study used a national health insurance database to screen 298,417 Taiwanese residents who were diagnosed with coronary heart disease from 2001 to 2015 for eligibility in the study and to evaluate select eligible patients with CHD–PUD from 2004 to 2015. Data were obtained from new users of clarithromycin (n = 4183) and nonusers of clarithromycin (n = 24,752) during follow-up. A total of 4070 eligible clarithromycin users and 4070 nonusers were subject to final analysis by 1:1 propensity score matching. Participants were followed up after receiving clarithromycin or at the corresponding date until the occurrence of cardiovascular morbidity in the presence of competing mortality, overall mortality and cardiovascular mortality, or through the end of 2015. The incidence rates and risks of overall mortality and cardiovascular outcomes were evaluated. The associations between clarithromycin and arrhythmia risk, as well as its dose and duration and overall mortality and cardiovascular outcomes were also addressed.
Results Clarithromycin users were associated with adjusted hazard ratios of 1.08 (95% confidence interval, 0.93–1.24; 21.5 compared with 21.2 per 1000 patient-years) for overall mortality, 0.95 (0.57–1.59; 1.5 compared with 1.8 per 1000 patient-years) for cardiovascular mortality, and 0.94 (0.89–1.09; 19.6 compared with 20.2 per 1000 patient-years) for cardiovascular morbidity in the presence of competing mortality, as compared with nonusers. We found no relationship between dose and duration of clarithromycin and overall mortality and cardiovascular outcomes and no increased risk of arrhythmia during follow-up period. After inclusion of arrhythmia events to re-estimate the risks of all study outcomes, the results remained insignificant.
Conclusion Concerning overall mortality, cardiovascular mortality, and cardiovascular morbidity, our results suggest clarithromycin-based therapy for Helicobacter pylori eradication may be safe in patients with stable CHD and subsequent PUD.

Abstract
BACKGROUND Peptic ulcer disease is one of the most common diseases in gastroenterology clinics. However, reported data about the global burden of peptic ulcer disease are still scarce. METHODS This was a secondary data analysis on the prevalence, mortality and disability-adjusted life years (DALYs) due to peptic ulcer disease by sex, age group and socio-demographic index (SDI) at the global level in 21 regions and 204 countries and territories between 1990 and 2019 using the Global Burden of Diseases, Injuries, and Risk Factors Study 2019. RESULTS Globally, the prevalence cases of peptic ulcer disease increased from 6 434 103 (95% uncertainty interval 5 405 963 to 7 627 971) in 1990 to 8 090 476 (6 794 576 to 9 584 000) in 2019. However, the age-standardized prevalence rate decreased from 143.4 (120.5 to 170.2) per 100 000 population in 1990 to 99.4 (83.9 to 117.5) per 100 000 population in 2019. Moreover, the age-standardized mortality rate decreased by 59.4% (55.3 to 63.1) and the DALYs rate fell by 60.6% (56.8 to 63.9) from 1990 to 2019. Across SDI quintiles, low-middle and low SDI quintiles had the highest age-standardized prevalence, mortality and DALYs rates from 1990 to 2019. CONCLUSION The age-standardized prevalence, mortality and DALYs estimates of peptic ulcer disease decreased from 1990 to 2019 globally, but more efforts are needed for the prevention, early diagnosis and treatment of peptic ulcer disease in low SDI and low-middle SDI groups of countries.

Pharm Res 2021; 38:1821-1838.

Abstract
AIMS Gastric ulcer is a continuous worldwide threat that inquires protective agents. Olmesartan (OLM) has potent anti-oxidant and anti-inflammatory characters, yet having limited bioavailability. We targeted the gastro-protective potential and probable mechanism of OLM and its niosomal form against indomethacin (IND) induced-gastric ulcer in rats. MAIN METHODS we prepared OLM niosomes (OLM-NIO) with different surfactant: cholesterol molar ratios. We evaluated particle size, zeta-potential, polydispersity, and entrapment efficiency. In-vitro release study, Fourier transform infrared spectroscopy, differential scanning calorimetry, and transmission electron microscopy were performed for selected niosomes. In-vivo, we used oral Omeprazole (30 mg/kg), OLM or OLM-NIO (10 mg/kg) for 3 days before IND (25 mg/kg) ingestion. We assessed gastric lesions, oxidative and inflammatory markers. KEY FINDINGS OLM-NIO prepared with span 60:cholesterol ratio (1:1) showed high entrapment efficiency 93 ± 2%, small particle size 159.3 ± 6.8 nm, low polydispersity 0.229 ± 0.009, and high zeta-potential -35.3 ± 1.2 mV, with sustained release mechanism by release data. In-vivo macroscopical and histological results showed gastro-protective effects of OLM pretreatment, which improved oxidative stress parameters and enhanced the gastric mucosal cyclooxygenase-1 (COX-1) and prostaglandin E2 (PGE2) contents. OLM pretreatment suppressed interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) contents and translocation of p38 mitogen-activated protein kinase (p38-MAPK). Besides, OLM substantially promoted the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) protective pathway. OLM-NIO furtherly improved all previous outcomes. SIGNIFICANCE We explored OLM anti-ulcerative effects, implicating oxidative stress and inflammation improvement, mediated by the Nrf2/HO-1 signaling pathway and p38-MAPK translocation. Meanwhile, the more bioavailable OLM-NIO achieved better gastro-protective effects compared to conventional OLM form.

Abstract
The gastrointestinal tract is a long tubular structure wherein any point in the mucosa along its entire length could be the source of a hemorrhage. Upper (esophagel and gastroduodenal) and lower (jejunum, ileum, and colon) gastrointestinal bleeding are common. Gastroduodenal and colonic bleeding are more frequent than bleeding from the small bowel, but nowadays the entire gastrointestinal tract can be explored endoscopically and bleeding lesions can be locally treated successfully to stop or prevent further bleeding. The extensive use of antiplatelet and anticoagulants drugs in cardiovascular patients is, at least in part, the cause of the increasing number of patients suffering from gastrointestinal bleeding. Patients with these conditions are usually older and more fragile because of their comorbidities. The correct management of antithrombotic drugs in cases of gastrointestinal bleeding is essential for a successful outcome for patients. The influence of the microbiome in the pathogenesis of small bowel bleeding is an example of the new data that are emerging as potential therapeutic target for bleeding prevention. This text summarizes the latest research and advances in all forms of acute gastrointestinal bleeding (i.e., upper, small bowel and lower). Diagnosis is approached, and medical, endoscopic or antithrombotic management are discussed in the text in an accessible and comprehensible way.

Abstract
This study analyzed the association of functionally significant SNPs of matrix metalloproteinase (MMP) genes in the development of peptic ulcer disease (PUD) in Caucasians from Central Russia. Ten SNPs of the MMP-1, MMP-2, MMP-3, MMP-8, and MMP-9 genes were analyzed for association with PUD in a cohort of 798 patients with PUD (including 404 H. pylori-positive and 394 H. pylori-negative) and 347 H. pylori-negative controls using logistic regression and assuming the additive, recessive, and dominant genetic models. The variants of MMP-1, MMP-2, MMP-3, and MMP-8 did not manifest any significant associations with the diseases. Five SNPs of the MMP-9 gene demonstrated such association. Allele G of the rs17576 MMP-9 locus conferred a higher risk for PUD (ORadj = 1.31, pperm = 0.016), haplotype AACG of loci rs17576-rs3787268-rs2250889-rs17577 of the MMP-9 gene decreased risk for PUD (ORadj = 0.17, pperm = 0.003). Also, allele C of rs3918249, allele G of rs17576 and haplotype CG of rs3918249-rs17576 of the MMP-9 gene increased risk for H. pylori-positive PUD (ORadj = 1.82, pperm = 0.002; ORadj = 1.53–1.95 pperm = 0.001–0.013 and ORadj = 1.49 pperm = 0.009 respectively). The above loci and 50 linked to them possess significant regulatory effects and may affect the alternative splicing of four genes and the expression of 17 genes in various organs and tissues related to the PUD pathogenesis.

Reshetnyak VI, Burmistrov AI, Maev IV. Helicobacter pylori: Commensal, symbiont or pathogen? World J Gastroenterol 2021; 27:545-560. [PMID: 33642828 PMCID: PMC7901052 DOI: 10.3748/wjg.v27.i7.545] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Revised: 12/28/2020] [Accepted: 01/21/2021] [Indexed: 02/06/2023] Open
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.

Abstract
Genetic factors are recognized to contribute to peptic ulcer disease (PUD) and other gastrointestinal diseases, such as gastro-oesophageal reflux disease (GORD), irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Here, genome-wide association study (GWAS) analyses based on 456,327 UK Biobank (UKB) individuals identify 8 independent and significant loci for PUD at, or near, genes MUC1, MUC6, FUT2, PSCA, ABO, CDX2, GAST and CCKBR. There are previously established roles in susceptibility to Helicobacter pylori infection, response to counteract infection-related damage, gastric acid secretion or gastrointestinal motility for these genes. Only two associations have been previously reported for duodenal ulcer, here replicated trans-ancestrally. The results highlight the role of host genetic susceptibility to infection. Post-GWAS analyses for PUD, GORD, IBS and IBD add insights into relationships between these gastrointestinal diseases and their relationships with depression, a commonly comorbid disorder.

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.

Abstract
BACKGROUND Helicobacter pylori is accounted as the most etiologic agent for digestive disorders, in particular, the most important of them i.e. peptic ulcer and gastric cancer. In the recent years, association of vacA genotypes and gastrointestinal disorders has attracted a lot of attention. In present study, we assessed the correlation between vacA genotypes (s1, s2, m1, m2, s1m1, s1m2, s2m1 and s2m2) and development to peptic ulcer in Iranian population. METHODS In our study, first, 24 original articles containing of information of 3328 patients were evaluated. Statistical analysis was done by Comprehensive Meta-Analysis version 2.0 software (Biostat, Englewood, NJ, USA). In this regards, we used from fixed-effects model for analysis of data with low heterogeneity, while for analysis of data with high heterogeneity (I2 statistic index > 25%, Cochrane Q statistic p value < 0.05), random-effects model was used. RESULTS Abundance of each of s1, s2, m1, m2, s1m1, s1m2, s2m1, and s2m2 was estimated 36.24, 28.32, 42.90 29.86, 27.88, 32.34, 15.70, and 25.94%, respectively. According to the results, the m1, s1, and s1m2 genotypes were among the most prevalent genotypes among the Iranian patients, whereas, s2m1 genotype had the lowest frequency. CONCLUSIONS Overall, 24 articles (total participants = 3328) were included in this comprehensive analysis. H. pylori infection rate were 90.26% in these cases, so that 33.65% of whom had peptic ulcer. Moreover, the abundance of each vacA genotypes including s1, s2, m1, m2, s1m1, s1m2, s2m1, and s2m2 was estimated as 36.24, 28.32, 42.90 29.86, 27.88, 32.34, 15.70, and 25.94% respectively. We demonstrated that there is a significant relationship between infection of stomach with m1, s1m1, and s2m1 genotypes and development to peptic ulcer disease.

Abstract
PURPOSE OF REVIEW We reviewed the recent medical literature to show global burden of gastroduodenal disease, potential strategies, and further perspectives. RECENT FINDINGS Gastrointestinal and liver diseases are growing health problems, and cause more than 8 million deaths per year worldwide; encompass a range of long-term health conditions, such as digestive cancers, gastroesophageal reflux disease, Helicobacter pylori infection, peptic ulcer disease, liver diseases, inflammatory bowel disease, coeliac disease, and functional gastrointestinal disorders. Scientific knowledge demonstrates that the noncommunicable disease burden can be greatly reduced if cost-effective preventive and curative actions, along with interventions for prevention and control of noncommunicable diseases already available, are implemented in an effective and balanced manner. SUMMARY Future research will have to elaborate on simple methods for preselection of patients at high risk to allow their implementation in strategies and respect all demand of cost-effectiveness. Understanding trends in GI illnesses could be helpful to meet the needs of patients and decrease the disease burden.

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.

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.

Association between depression and subsequent peptic ulcer occurrence among older people living alone: A prospective study investigating the role of change in social engagement.

Abstract
OBJECTIVE To examine whether baseline depression predicts subsequent peptic ulcer disease (PUD) in older people living alone and whether social engagement plays a role in such an association. METHODS Between May 2010 and May 2015, 2, 850 older people living alone were recruited from eight Grade-A hospitals in the People's Republic of China and followed for up to 36 months. The Kaplan-Meier method was used to investigate how the incidence of PUD varied with depression and social engagement status. Multivariate Cox proportional hazards models were estimated to examine the association between depression and incidence of PUD and assess the role of social engagement in this relationship. RESULTS Kaplan-Meier curves indicated that the 36-month cumulative incidence of PUD was higher in depressed (10.1%) than non-depressed participants (5.3%). However, among the depressed participants, increased or continued social engagement reduced the incidence to 6.2% and 7.9%, respectively. Multivariate analyses showed that baseline depression was associated with subsequent PUD development (hazard ratio [HR] = 2.520, 95% confidence interval [CI]: 1.525-3.356). The incidence of PUD was similar in non-depressed and depressed participants who reported increased (HR = 1.956, 95% CI: 0.913-3.374) or continued social engagement (HR = 1.827, 95% CI: 0.918-3.690) during the follow-up period. However, depressed participants who reported decreased (HR = 2.485, 95% CI: 1.459-3.295) or no social engagement (HR = 2.896, 95% CI: 1.817-4.228) were more likely to develop PUD than those without depression. CONCLUSIONS Baseline depression was associated with subsequent incidence of PUD, but this association appears to be reduced by increased or continued social engagement.

Abstract
Peptic ulcer is a chronic disease affecting up to 10% of the world's population. The formation of peptic ulcers depends on the presence of gastric juice pH and the decrease in mucosal defenses. Non-steroidal anti-inflammatory drugs (NSAIDs) and Helicobacter pylori (H. pylori) infection are the two major factors disrupting the mucosal resistance to injury. Conventional treatments of peptic ulcers, such as proton pump inhibitors (PPIs) and histamine-2 (H2) receptor antagonists, have demonstrated adverse effects, relapses, and various drug interactions. On the other hand, medicinal plants and their chemical compounds are useful in the prevention and treatment of numerous diseases. Hence, this review presents common medicinal plants that may be used for the treatment or prevention of peptic ulcers.

Abstract
Peptic ulcer bleeding remains an important medical emergency. Important recent advances are reviewed. These include further support for a more restrictive transfusion strategy aiming for a target haemoglobin of 70-90 g/L. The Glasgow-Blatchford score remains the most useful assessment score for identifying the lowest risk patients suitable for outpatient management and predicting the need for intervention. Newer scores such as the AIMS65 and Progetto Nazionale Emorragia Digestive score (PNED) may be more accurate in predicting mortality. Pre-endoscopy erythromycin improves outcomes and is underused. A new disposable Doppler probe appears to provide more accurate determination of both rebleeding risk and the success of endoscopic therapy than purely visual guidance. Over-the-scope clips and haemostatic powders appear to have some role as endoscopic salvage therapies. Non- H. pylori, non-aspirin/non-steroidal anti-inflammatory drug (NSAID) ulcers contribute to an increasing percentage of bleeding peptic ulcers and are associated with a high rebleeding rate. The optimal management of these ulcers remains to be determined.

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
Introducción. Por lo general, se ha descrito que la localización duodenal de la úlcera es más frecuente que la localización gástrica; sin embargo, en áreas con alta incidencia de cáncer gástrico la úlcera péptica parece tener una distribución anatómica distinta, existiendo predominio de la localización gástrica.Objetivo. Realizar una revisión narrativa de la literatura acerca de la distribución anatómica de la úlcera péptica en áreas con alta y baja incidencia de cáncer gástrico.Materiales y métodos. Se realizó una búsqueda estructurada de la literatura en las bases de datos ProQuest, EBSCO, ScienceDirect, PubMed, LILACS, Embase, Trip, SciELO y Cochrane Library con los términos “Peptic ulcer” AND “stomach neoplasm”; la búsqueda se hizo en inglés con sus equivalentes en español y se limitó a estudios observacionales, cohortes y casos y controles.Resultados. Se encontraron alrededor de 50 artículos con información relevante para la presente revisión.Conclusión. La literatura disponible sugiere que la úlcera péptica predomina en áreas donde el cáncer gástrico tiene alta incidencia, mientras que en zonas donde la incidencia de la neoplasia es baja predomina la localización duodenal.

Abstract
OBJECTIVES The incidence and complications of peptic ulcer disease (PUD) have declined, but mortality from bleeding ulcers has remained unchanged. The aims of the current study were to evaluate the significance of PUD among patients admitted for acute upper endoscopy and to evaluate the survival of PUD patients. PATIENTS AND METHODS In this prospective, observational cohort study, data on 1580 acute upper endoscopy cases during 2012-2014 were collected. A total of 649 patients were included with written informed consent. Data on patients' characteristics, living habits, comorbidities, drug use, endoscopy and short-term and long-term survival were collected. RESULTS Of all patients admitted for endoscopy, 147/649 (23%) had PUD with the main symptom of melena. Of these PUD patients, 35% had major stigmata of bleeding (Forrest Ia-IIb) in endoscopy. Patients with major stigmata had significantly more often renal insufficiency, lower level of blood pressure with tachycardia and lower level of haemoglobin, platelets and ratio of thromboplastin time. No differences in drug use, Charlson comorbidity class, BMI, smoking or alcohol use were found. Of the PUD patients, 31% were Helicobacter pylori positive. The 30-day mortality was 0.7% (95% confidence interval: 0.01-4.7), 1-year mortality was 12.9% (8.4-19.5) and the 2-year mortality was 19.4% (13.8-26.8), with no difference according to major or minor stigmata of bleeding. Comorbidity (Charlson>1) was associated with decreased survival (P=0.029) and obesity (BMI≥30) was associated with better survival (P=0.023). CONCLUSION PUD is still the most common cause for acute upper endoscopy with very low short-term mortality. Comorbidity, but not the stigmata of bleeding, was associated with decreased long-term survival.

Abstract
Acute upper gastrointestinal haemorrhage due to peptic ulcer bleeding remains an important cause of emergency presentation and hospital admission. Despite advances in many aspects of management, peptic ulcer bleeding is still associated with significant morbidity, mortality, and healthcare costs. Comprehensive international guidelines have been published, but advances as well as controversies continue to evolve. Important recent advances include the evidence supporting a more restrictive transfusion strategy aiming for a target haemoglobin of 70–90 g/l. Comparative studies have confirmed that the Glasgow–Blatchford score remains the most useful score for predicting the need for intervention as well as for identifying the lowest-risk patients suitable for outpatient management. New scores, including the AIMS65 and Progetto Nazionale Emorragia Digestiva score, may be more accurate in predicting mortality. Pre-endoscopy erythromycin appears to improve outcomes and is probably underused. High-dose oral proton pump inhibition (PPI) for 11 days after PPI infusion is advantageous in those with a Rockall score of 6 or more. Oral is as effective as parenteral iron at restoring haemoglobin levels after a peptic ulcer bleed and both are superior to placebo in this respect. Within endoscopic techniques, haemostatic powders and over-the-scope clips can be used when other methods have failed. A disposable Doppler probe appears to provide more accurate determination of both rebleeding risk and the success of endoscopic therapy than purely visual guidance. Non-
Helicobacter pylori, non-aspirin/non-steroidal anti-inflammatory drug ulcers contribute an increasing percentage of bleeding peptic ulcers and are associated with a poor prognosis and high rebleeding rate. The optimal management of these ulcers remains to be determined.

Abstract
The rapidly declining prevalence of Helicobacter pylori infection and widespread use of potent anti-secretory drugs means peptic ulcer disease has become substantially less prevalent than it was two decades ago. Management has, however, become more challenging than ever because of the threat of increasing antimicrobial resistance worldwide and widespread use of complex anti-thrombotic therapy in the ageing population. Peptic ulcers not associated with H pylori infection or the use of non-steroidal anti-inflammatory drugs are now also imposing substantial diagnostic and therapeutic challenges. This Seminar aims to provide a balanced overview of the latest advances in the pathogenetic mechanisms of peptic ulcers, guidelines on therapies targeting H pylori infection, approaches to treatment of peptic ulcer complications associated with anti-inflammatory analgesics and anti-thrombotic agents, and the unmet needs in terms of our knowledge and management of this increasingly challenging condition.

Abstract
The primary study objectives were to estimate the frequencies and rates of gastrointestinal bleeding and peptic ulcerative disorder in HIV-positive patients compared with age- and sex-matched HIV-negative subjects. Data from a US insurance claims database was used for this analysis. Among 89,207 patients with HIV, 9.0% had a GI bleed, 1.0% had an upper gastrointestinal bleed, 5.6% had a lower gastrointestinal bleed, 1.9% had a peptic ulcerative disorder diagnosis, and 0.6% had both gastrointestinal/peptic ulcerative disorder. Among 267,615 HIV-negative subjects, the respective frequencies were 6.9%, 0.6%, 4.3%, 1.4%, and 0.4% (p<0.0001 for each diagnosis subcategory). After combining effect measure modifiers into comedication and comorbidity strata, gastrointestinal bleeding hazard ratios (HRs) were higher for HIV-positive patients without comedication/comorbidity, and those with comedication alone (HR, 2.73; 95% confidence interval [CI], 2.62-2.84; HR, 1.59; 95% CI, 1.47-1.71). The rate of peptic ulcerative disorder among those without a history of ulcers and no comorbidity/comedication was also elevated (HR, 2.72; 95% CI, 2.48-2.99). Hazard ratios of gastrointestinal bleeding, and peptic ulcerative disorder without a history of ulcers were lower among patients infected with HIV with comedication/comorbidity (HR, 0.64; 95% CI, 0.56-0.73; HR, 0.46; 95% CI, 0.33-0.65). Rates of gastrointestinal bleeding plus peptic ulcerative disorder followed a similar pattern. In summary, the rates of gastrointestinal/peptic ulcerative disorder events comparing HIV-infected subjects to non-HIV-infected subjects were differential based on comorbidity and comedication status.

Abstract
AIM To elucidate the epidemiological characteristics and associated risk factors of perforated peptic ulcer (PPU).
METHODS We retrospectively reviewed medical records of patients who were diagnosed with benign PPU from 2010 through 2015 at 6 Hallym university-affiliated hospitals.
RESULTS A total of 396 patients were identified with postoperative complication rate of 9.1% and mortality rate of 0.8%. Among 174 (43.9%) patients who were examined for Helicobacter pylori (H. pylori) infection, 78 (44.8%) patients were positive for H. pylori infection, 21 (12.1%) were on non-steroidal anti-inflammatory drugs (NSAIDs) therapy, and 80 (46%) patients were neither infected of H. pylori nor treated by any kinds of NSAIDs. Multivariate analysis indicated that older age (OR = 1.09, 95%CI: 1.04-1.16) and comorbidity (OR = 4.11, 95%CI: 1.03-16.48) were risk factors for NSAID-associated PPU compared with non-H. pylori, non-NSAID associated PPU and older age (OR = 1.04, 95%CI: 1.02-1.07) and alcohol consumption (OR = 2.08, 95%CI: 1.05-4.13) were risk factors for non-H. pylori, non-NSAID associated PPU compared with solely H. pylori positive PPU.
CONCLUSION Elderly patients with comorbidities are associated with NSAIDs-associated PPU. Non-H. pylori, non-NSAID peptic ulcer is important etiology of PPU and alcohol consumption is associated risk factor.

Abstract
OBJECTIVE Mortality rates in complicated peptic ulcer disease are high. This study aimed to examine the prognostic importance of ulcer site in patients with peptic ulcer bleeding (PUB) and perforated peptic ulcer (PPU). DESIGN a nationwide cohort study with prospective and consecutive data collection. POPULATION all patients treated for PUB and PPU at Danish hospitals between 2003 and 2014. DATA demographic and clinical data reported to the Danish Clinical Registry of Emergency Surgery. OUTCOME MEASURES 90- and 30-d mortality and re-intervention. STATISTICS the crude and adjusted association between ulcer site (gastric and duodenal) and the outcome measures of interest were assessed by binary logistic regression analysis. RESULTS Some 20,059 patients with PUB and 4273 patients with PPU were included; 90-d mortality was 15.3% for PUB and 29.8% for PPU; 30-d mortality was 10.2% and 24.7%, respectively. Duodenal bleeding ulcer, as compared to gastric ulcer (GU), was associated with a significantly increased risk of all-cause mortality within 90 and 30 d, and with re-intervention: adjusted odds ratio (OR) 1.47 (95% confidence interval 1.30-1.67); p < 0.001, OR 1.60 (1.43-1.77); p < 0.001, and OR 1.86 (1.68-2.06); p < 0.001, respectively. There was no difference in outcomes between gastric and duodenal ulcers (DUs) in PPU patients: adjusted OR 0.99 (0.84-1.16); p = 0.698, OR 0.93 (0.78 to 1.10); p = 0.409, and OR 0.97 (0.80-1.19); p = 0.799, respectively. CONCLUSIONS DU site is a significant predictor of death and re-intervention in patients with PUB, as compared to GU site. This does not seem to be the case for patients with PPU.

Abstract
BACKGROUND Incidence and complications of peptic ulcer disease (PUD) have declined, but mortality from peptic ulcer bleeding has remained unchanged. The few recent studies on mortality associated with both uncomplicated and complicated patients with peptic ulcer disease provide contradictory results. AIMS To evaluate short- and long-term mortality, and the main causes of death in peptic ulcer disease. METHODS In this retrospective epidemiologic cohort study, register data on 8146 adult patients hospitalised with peptic ulcer disease during 2000-2008 were collected in the capital region of Finland. All were followed in the National Cause of Death Register until the end of 2009. The data were linked with the nationwide Drug Purchase Register of the Finnish Social Insurance Institution. RESULTS Mean follow-up time was 4.9 years. Overall mortality was substantially increased, standardised mortality ratio 2.53 (95% CI: 2.44-2.63); 3.7% died within 30 days, and 11.8% within 1 year. At 6 months, the survival of patients with perforated or bleeding ulcer was lower compared to those with uncomplicated ulcer; hazard ratios were 2.06 (1.68-2.04) and 1.32 (1.11-1.58), respectively. For perforated duodenal ulcers, both the short- and long-term survival was significantly impaired in women. The main causes of mortality at 1 year were malignancies and cardiovascular diseases. Previous use of statins was associated with significant reduction in all-cause mortality. CONCLUSIONS One-year mortality in patients hospitalised with peptic ulcer disease remained high with no change. This peptic ulcer disease cohort had a clearly decreased survival rate up to 10 years, especially among women with a perforated duodenal ulcer, most likely explained by poorer survival due to underlying comorbidity.

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
An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.

Abstract
Although the incidence of nonvariceal upper gastrointestinal bleeding (UGIB) has been decreasing worldwide, nonvariceal UGIB continues to be a significant problem. Even with the advent of advanced endoscopic procedures and potent medications to suppress acid production, UGIB carries significant morbidity and mortality. Some of the most common risk factors for nonvariceal UGIB include Helicobacter pylori infection, nonsteroidal antiinflammatory drugs (NSAIDs), aspirin, selective serotonin reuptake inhibitors, and other antiplatelet and anticoagulant medications. In patients with cardiovascular disease and kidney disease, UGIB tends to be more severe and has greater morbidity. Many of the newer NSAIDs have been removed from the market.

A multicenter prospective study on the prevalence of Helicobacter pylori-negative and nonsteroidal anti-inflammatory drugs-negative idiopathic peptic ulcers in Japan. J Gastroenterol Hepatol 2015; 30:842-8. [PMID: 25532720 DOI: 10.1111/jgh.12876] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 12/15/2014] [Indexed: 12/13/2022]
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
Background Peptic ulcer etiology has been changing because of H. pylori decline. Objectives To estimate peptic ulcer prevalence in 10 years-interval and compare the association with H. pylori and use of non-steroidal anti-inflammatory drugs. Methods Records assessment in two periods: A (1997-2000) and B (2007-2010), searching for peptic ulcer, H. pylori infection and non-steroidal anti-inflammatory drugs use. Results Peptic ulcer occurred in 30.35% in A and in 20.19% in B. H. pylori infection occurred in 73.3% cases in A and in 46.4% in B. Non-steroidal anti-inflammatory drugs use was 3.5% in A and 13.3% in B. Neither condition occurred in 10.4% and 20.5% in A and B respectively. Comparing both periods, we observed reduction of peptic ulcer associated to H. pylori (P=0.000), increase of peptic ulcer related to non-steroidal anti-inflammatory drugs (P=0.000) and idiopathic peptic ulcer (P=0.002). The concurrent association of H. pylori and non-steroidal anti-inflammatory drugs was also higher in B (P=0.002). Rates of gastric ulcer were higher and duodenal ulcer lower in the second period. Conclusions After 10 years, the prevalence of peptic ulcer decreased, as well as ulcers related to H. pylori whereas ulcers associated to non-steroidal anti-inflammatory drugs increased. There was an inversion in the pattern of gastric and duodenal ulcer and a rise of idiopathic peptic ulcer.

Abstract
PURPOSE OF REVIEW This review summarizes the past year's literature regarding the neural, paracrine, hormonal, and intracellular regulation of gastric acid secretion. RECENT FINDINGS Gastric acid facilitates the digestion of protein as well as the absorption of iron, calcium, vitamin B12, and certain medications. High gastric acidity, in combination with pepsin and lipase, kills ingested microorganisms and may play a role in preventing bacterial overgrowth, enteric infection, and possibly spontaneous bacterial peritonitis, community-acquired pneumonia, and infection with Mycobacterium tuberculosis. Stimulants of acid secretion include histamine, gastrin, acetylcholine, and ghrelin. Inhibitors include somatostatin, gastric inhibitory polypeptide, calcitonin gene-related peptide, and adrenomedullin. Helicobacter pylori stimulates or inhibits depending upon the time course of infection and the area of the stomach predominantly infected. Proteins implicated in H-K-ATPase membrane trafficking include myosin IIB, F-actin, ezrin, and Rab GTPases. SUMMARY Our understanding of the regulation of gastric acid secretion continues to advance. Such knowledge is crucial for the management of acid-peptic disorders and the development of novel medications, such as cholecystokinin-2 receptor antagonists.

Abstract
BACKGROUND Prevalence of gastroduodenal lesions is changing in the last decades. Prevalence of Helicobacter pylori infection, non-steroidal anti-inflammatory drugs (NSAIDs), and proton pump inhibitor (PPI) therapy may be involved in such a phenomenon. We assessed gastroduodenal lesions prevalence in a nationwide study. MATERIALS AND METHODS Consecutive patients who underwent upper endoscopy for the first time in 24 Italian centres between January 2012 and 31 March 2012 were enrolled. Prevalence of gastric ulcer (GU), duodenal ulcer (DU), gastric erosions (GE), duodenal erosions (DE), gastric polyp (GP), Barrett's oesophagus (BE), and neoplasia was assessed. RESULTS Overall, 1054 (M/F: 388/666; Mean age: 57.5 ± 5 years) patients were enrolled. H. pylori infection was detected in 356 (33.9%) patients, 358 (34%) were taking NSAIDs, and 532 (50.5%) PPIs. PPI therapy was associated with a significantly lower H. pylori detection rate (27.8% vs 39.8%; OR: 0.6, 95% CI 0.45-0.77; P<0.001). GU, DU, GE, DE, GP and BE were detected in 17 (1.6%), 13 (1.2%), 150 (14.2%), 50 (4.7%), 51 (4.8%) and 17 (1.6%), respectively. Moreover, 3 (0.3%) distal gastric cancers were observed. H. pylori infection remained the most prevalent factor for all gastroduodenal lesions, but gastric polyp. One third of patients with GU and GE were taking only NSAIDs therapy. CONCLUSIONS The prevalence of peptic ulcer was very low (<3%), with a similar rate between DU and GU. As many as half patients were on ongoing PPI therapy. Such a therapy could affect both the detection rate of H. pylori infection and the real prevalence of gastroduodenal lesions.

Abstract
The discovery of Helicobacter pylori three decades ago is a modern medical success story. It markedly changed our understanding of the pathophysiology of gastroduodenal diseases and led to an improvement in the treatment of diseases related to H. pylori infection. Many of these diseases (such as ulcer disease and mucosal associated lymphoid tissue lymphoma) have become curable, and others (gastric cancer) might be preventable with the application of H. pylori eradication therapy. Since its discovery, H. pylori has also been identified as a trigger for some extragastric diseases. Promising results in this exciting field might have a clinical effect in the near future. This Timeline gives an overview of the success of clinical research on H. pylori to date and highlights some future trends in this area.

Abstract
Helicobacter pylori (H. pylori) infection is the main pathogenic factor for upper digestive tract organic diseases. In addition to direct cytotoxic and proinflammatory effects, H. pylori infection may also induce abnormalities indirectly by affecting the brain-gut axis, similar to other microorganisms present in the alimentary tract. The brain-gut axis integrates the central, peripheral, enteric and autonomic nervous systems, as well as the endocrine and immunological systems, with gastrointestinal functions and environmental stimuli, including gastric and intestinal microbiota. The bidirectional relationship between H. pylori infection and the brain-gut axis influences both the contagion process and the host’s neuroendocrine-immunological reaction to it, resulting in alterations in cognitive functions, food intake and appetite, immunological response, and modification of symptom sensitivity thresholds. Furthermore, disturbances in the upper and lower digestive tract permeability, motility and secretion can occur, mainly as a form of irritable bowel syndrome. Many of these abnormalities disappear following H. pylori eradication. H. pylori may have direct neurotoxic effects that lead to alteration of the brain-gut axis through the activation of neurogenic inflammatory processes, or by microelement deficiency secondary to functional and morphological changes in the digestive tract. In digestive tissue, H. pylori can alter signaling in the brain-gut axis by mast cells, the main brain-gut axis effector, as H. pylori infection is associated with decreased mast cell infiltration in the digestive tract. Nevertheless, unequivocal data concerning the direct and immediate effect of H. pylori infection on the brain-gut axis are still lacking. Therefore, further studies evaluating the clinical importance of these host-bacteria interactions will improve our understanding of H. pylori infection pathophysiology and suggest new therapeutic approaches.
