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
INTRODUCTION Esophageal cancer (EC) is one of the most common malignant tumors of the upper gastrointestinal tract. The etiology of EC is complicated and increasing evidence has shown that microbial infection is closely related to the occurrence of various malignant tumors. Though many studies have been focused on this subject in recent years, the exact relationship between microbial infection and the occurrence of EC remains unclear. AREAS COVERED In this review, we searched all eligible literature reports, summarized the most recent studies in this research field, and analyzed the pathogenic microorganisms associated with EC, providing the latest evidence and references for the prevention of pathogenic microorganism-related EC. EXPERT OPINION In recent years, increasing evidence has shown that pathogenic microbial infections are closely associated with the development of EC. Therefore, it is necessary to describe in detail the relationship between microbial infection and EC and clarify its possible pathogenic mechanism, which will shed a light on clinical prevention and treatment of cancer caused by pathogenic microbial infection.

Abstract
BACKGROUND Helicobacter pylori ( H. pylori ) can persistently colonize on the gastric mucosa after infection and cause gastritis, atrophy, metaplasia, and even gastric cancer (GC). METHODS Therefore, the detection and eradication of H. pylori are the prerequisite. RESULTS Clinically, there are some controversial issues, such as why H. pylori infection is persistent, why it translocases along with the lesser curvature of the stomach, why there is oxyntic antralization, what the immunological characteristic of gastric chronic inflammation caused by H. pylori is, whether H. pylori infection is associated with extra-gastric diseases, whether chronic atrophic gastritis (CAG) is reversible, and what the potential problems are after H. pylori eradication. What are the possible answers? CONCLUSION In the review, we will discuss these issues from the attachment to eradication in detail.

Abstract
Esophageal cancer (EC) is the ninth most common cancer and the sixth leading cause of cancer deaths worldwide. Esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC) are the two main histological subtypes with distinct epidemiological and clinical features. While the global incidence of ESCC is declining, the incidence of EAC is increasing in many countries. Decades of epidemiologic research have identified distinct environmental exposures for ESCC and EAC subtypes. Recent advances in understanding the genomic aspects of EC have advanced our understanding of EC causes and led to using specific genomic alterations in EC tumors as biomarkers for early diagnosis, treatment, and prognosis of this cancer. Nevertheless, the prognosis of EC is still poor, with a five-year survival rate of less than 20%. Currently, there are significant challenges for early detection and secondary prevention for both ESCC and EAC subtypes, but Cytosponge™ is shifting this position for EAC. Primary prevention remains the preferred strategy for reducing the global burden of EC. In this review, we will summarize recent advances, current status, and future prospects of the studies related to epidemiology, time trends, environmental risk factors, prevention, early diagnosis, and treatment for both EC subtypes.

[PMID: 36034104 PMCID: PMC9403448 DOI: 10.1177/20406223221117971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Accepted: 07/19/2022] [Indexed: 11/25/2022] Open
Abstract
Background and Aims: Barrett’s esophagus (BE) is the only recognized precursor for esophageal
adenocarcinoma. Helicobacter pylori (H.
pylori) infection is a major contributing factor towards upper
gastrointestinal diseases, but its relationship with BE remains
controversial. Some previous studies suggested that H.
pylori infection negatively correlated with BE, while others
did not. This may be attributed to the difference in the selection of
control groups among studies. The present meta-analysis aims to clarify
their association by combining all available data from well-designed
studies. Methods: The PubMed, EMBASE, and Cochrane
Library databases were searched. Odds ratios (ORs) with 95%
confidence intervals (CIs) were pooled by a random-effects model.
Heterogeneity was evaluated using the Cochran’s Q test and
I2 statistics. Meta-regression, subgroup,
and leave-one-out sensitivity analyses were employed to explore the sources
of heterogeneity. Results: Twenty-four studies with 1,354,369 participants were included. Meta-analysis
found that patients with BE had a significantly lower prevalence of
H. pylori infection than those without (OR = 0.53, 95%
CI = 0.45–0.64; p < 0.001). The heterogeneity was
statistically significant (I² = 79%;
p < 0.001). Meta-regression, subgroup, and leave-one-out
sensitivity analyses did not find any source of heterogeneity. Meta-analysis
of 7 studies demonstrated that CagA-positive H. pylori
infection inversely correlated with BE (OR = 0.25, 95% CI = 0.15–0.44;
p = 0.000), but not CagA-negative H.
pylori infection (OR = 1.22, 95% CI = 0.90–1.67;
p = 0.206). Meta-analysis of 4 studies also
demonstrated that H. pylori infection inversely correlated
with LSBE (OR = 0.39, 95% CI = 0.18–0.86; p = 0.019), but
not SSBE (OR = 0.73, 95% CI = 0.30–1.77; p = 0.484). Conclusion: H. pylori infection negatively correlates with BE. More
experimental studies should be necessary to elucidate the potential
mechanisms in future.

Abstract
Barrett's oesophagus (BE) is the precursor of oesophageal adenocarcinoma, which has become the most common type of oesophageal cancer in many Western populations. Existing evidence on diet and risk of BE predominantly comes from case-control studies, which are subject to recall bias in measurement of diet. We aimed to investigate the potential effect of diet, including macronutrients, carotenoids, food groups, specific food items, beverages and dietary scores, on risk of BE in over 20 000 participants of the Melbourne Collaborative Cohort Study. Diet at baseline (1990-1994) was measured using a food frequency questionnaire. The outcome was BE diagnosed between baseline and follow-up (2007-2010). Logistic regression models were used to estimate OR and 95 % CI for diet in relation to risk of BE. Intakes of leafy vegetables and fruit were inversely associated with risk of BE (highest v. lowest quartile: OR = 0·59; CI: 0·38, 0·94; P-trend = 0·02 and OR = 0·58; CI: 0·37, 0·93; P-trend = 0·02 respectively), as were dietary fibre and carotenoids. Stronger associations were observed for food than the nutrients found in them. Positive associations were observed for discretionary food (OR = 1·54; CI: 0·97, 2·44; P-trend = 0·04) and total fat intake (OR per 10 g/d = 1·11; CI: 1·00, 1·23), the association for fat was less robust in sensitivity analyses. No association was observed for meat, protein, dairy products or diet scores. Diet is a potential modifiable risk factor for BE. Public health and clinical guidelines that incorporate dietary recommendations could contribute to reduction in risk of BE and, thereby, oesophageal adenocarcinoma.

Mechanisms for the sex-specific effect of H. pylori on risk of gastroesophageal reflux disease and Barrett's oesophagus. Cancer Epidemiol Biomarkers Prev 2022; 31:1630-1637. [PMID: 35654416 DOI: 10.1158/1055-9965.epi-22-0234] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 04/22/2022] [Accepted: 05/24/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Mechanisms for how Helicobacter pylori infection affects risk of gastroesophageal reflux disease (GERD) and Barrett's oesophagus (BE) are incompletely understood and might differ by sex. METHODS In a case-control study nested in the Melbourne Collaborative Cohort Study with 425 GERD cases and 169 BE cases (identified at 2007-10 follow-up), we estimated sex-specific odds ratios for participants who were H. pylori seronegative versus seropositive at baseline (1990-94). To explore possible mechanisms, we 1) compared patterns of H. pylori-induced gastritis by sex using serum pepsinogen-I and gastrin-17 data and 2) quantified the effect of H. pylori seronegativity on BE mediated by GERD using causal mediation analysis. RESULTS For men, H. pylori seronegativity was associated with 1.69-fold (CI:1.03-2.75) and 2.28-fold (CI:1.27-4.12) higher odds of GERD and BE, respectively. No association was observed for women. H. pylori-induced atrophic antral gastritis was more common in men (68%) than in women (56%; p=0.015). For men, 5 of the 15 per 1,000 excess BE risk from being seronegative was mediated by GERD. CONCLUSIONS Men, but not women, who were H. pylori seronegative had increased risks of GERD and BE. A possible explanation might be sex-differences in patterns of H. pylori-induced atrophic antral gastritis, which could lead to less erosive reflux for men. Evidence of GERD mediating the effect of H. pylori on BE risk among men supports this proposed mechanism. IMPACT The findings highlight the importance of investigating sex differences in the effect of H. pylori on risk of GERD and BE in future studies.

Abstract
BACKGROUND Prediction of tissue origin of esophagogastric junction (EGJ) adenocarcinomas can be important for therapeutic decision, but no molecular marker is available. Here, we aimed to develop such a marker taking advantage of tissue-specific profiles of DNA methylation. METHODS DNA methylation profiles of gastric adenocarcinomas (GACs) were obtained by an Infinium HumanMethylation450 BeadChip array, and those of esophageal adenocarcinoma (EACs) were obtained from the TCGA database. DNA from formalin-fixed paraffin-embedded (FFPE) samples was analyzed by bisulfite pyrosequencing. RESULTS In the screening set, 51 of 145,841 CpG sites in CpG islands were methylated at significantly higher levels in 30 GACs compared to those in 30 EACs. Among them, SLC46A3 and cg09177106 were unmethylated in all the 30 EACs. Predictive powers of these two markers were successfully confirmed in an independent validation set (18 GACs and 18 EACs) (SLC46A3, sensitivity = 77.8%, specificity = 100%; cg09177106, sensitivity = 83.3%, specificity = 94.4%), and could be applied to FFPE samples (37 GACs and 18 EACs) (SLC46A3, P = 0.0001; cg09177106, P = 0.0028). On the other hand, EAC-specific markers informative in the FFPE samples could not be isolated. Using these GAC-specific markers, nine of 46 (19.6%) TCGA EGJ adenocarcinomas were predicted to be GACs. CONCLUSIONS Two GAC-specific markers, SLC46A3 and cg09177106, had a high specificity for identifying the tissue origin of EGJ adenocarcinoma.

Abstract
Esophageal cancer is one of the most common types of gastrointestinal malignancies that is encountered. It has a global distribution and affects males and females and is linked to significant morbidity and mortality. The mechanisms underlying pathophysiology are multifactorial and involve the interaction of genetic and environmental factors. This review article describes the immunological and metabolic changes that occur in malignancy of the esophagus.

Wang SE, Kendall BJ, Hodge AM, Dixon-Suen SC, Dashti SG, Makalic E, Williamson EM, Thomas RJS, Giles GG, English DR. Demographic and lifestyle risk factors for gastroesophageal reflux disease and Barrett's esophagus in Australia. Dis Esophagus 2022; 35:6354029. [PMID: 34409990 DOI: 10.1093/dote/doab058] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2021] [Revised: 07/23/2021] [Accepted: 07/31/2021] [Indexed: 12/11/2022]
Abstract
We examined demographic and lifestyle risk factors for incidence of gastroesophageal reflux disease (GERD) and Barrett's esophagus (BE) in an Australian cohort of 20,975 participants aged 40-63 at recruitment (1990-1994). Information on GERD and BE was collected between 2007 and 2010. GERD symptoms were defined as self-reported heartburn or acid regurgitation. BE was defined as endoscopically confirmed columnar-lined esophagus. Risk factors for developing GERD symptoms, BE diagnosis, age at symptom onset, and age at BE diagnosis were quantified using regression. During a mean follow-up of 15.8 years, risk of GERD symptoms was 7.5% (n = 1,318) for daily, 7.5% (n = 1,333) for 2-6 days/week, and 4.3% (n = 751) for 1 day/week. There were 210 (1.0%) endoscopically diagnosed BE cases, of whom 141 had histologically confirmed esophageal intestinal metaplasia. Female sex, younger age, lower socioeconomic position (SEP) and educational attainment, and former smoking were associated with higher GERD risk. Male sex and smoking were associated with earlier GERD symptom onset. Men, older participants, those with higher SEP, and former smokers were at higher BE risk. There was some evidence higher SEP was associated with earlier BE diagnosis. GERD and BE had different demographic risk factors but shared similar lifestyle factors. Earlier GERD symptom onset for men and smokers might have contributed to higher BE risk. The SEP patterns observed for GERD and BE suggest potential inequity in access to care. These findings would be important in the development of clinical risk prediction models for early detection of BE.

Barrett's esophagus: results from an Italian cohort with tight endoscopic surveillance. ACTA BIO-MEDICA : ATENEI PARMENSIS 2022; 93:e2022130.

Abstract
BACKGROUND AND AIM Barrett's Esophagus represents a condition that predisposes to the development of esophageal adenocarcinoma. The aim of the present study was to analyze the demographic and clinical characteristics of patients with BE, to establish the presence of risk factors for this condition, and to determine the frequency of dysplastic lesions as well as the evolution towards adenocarcinoma under tight endoscopic control. METHODS In this study, we retrospectively collected and analyzed data from a cohort of patients with Barrett's Esophagus identified through endoscopic records of ULSS7 in Northern Italy, who underwent upper esophagogastroduodenoscopy over a 10-year period from July 2008 to December 2020. RESULTS A total of 264 patients were identified as having BE and included in the study. Mean follow-up was 6.7 years (range: 3 months-13 years). Demographic characteristics of the study population included mean age of 62.7 years (range 33-90 years), with 62.5% of the study population being aged 60 or older, and a male predominance. Females were significantly older than males (65.7 years, range 37-90 vs 61.9 years, range 33-87, p=0.043, respectively). CONCLUSIONS The present study confirms the importance of tight endoscopic control in the management of BE, favoring early detection of BE degeneration towards high-grade dysplasia or adenocarcinoma. In a subset of patients with high-risk factors including male sex, cigarette smoking and heavy alcohol intake, it may be worthwhile to consider endoscopic control over time in order to detect the development of BE.

Abstract
In many countries alike, the time trends of gastric cancer, gastric and duodenal ulcer, ulcerative colitis, Crohn's disease, and colorectal cancer are characterized by similar birth-cohort patterns. Mortality from these diagnoses rose in cohorts born during the 19th century and then fell in subsequent cohorts born during the 20th century.

Abstract
BACKGROUND Helicobacter pylori (Hp) is a class I carcinogen in gastric carcinogenesis, but its role in Barrett's esophagus (BE) is unknown. Therefore, we aimed to explore the possible relationship. METHODS We reviewed observational studies published in English until October 2019. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for included studies. RESULTS 46 studies from 1505 potential citations were eligible for inclusion. A significant inverse relationship with considerable heterogeneity was found between Hp (OR = 0.70; 95% CI, 0.51-0.96; P = 0.03) and BE, especially the CagA-positive Hp strain (OR = 0.28; 95% CI, 0.15-0.54; P = 0.0002). However, Hp infection prevalence was not significantly different between patients with BE and the gastroesophageal reflux disease (GERD) control (OR = 0.99; 95% CI, 0.82-1.19; P = 0.92). Hp was negatively correlated with long-segment BE (OR = 0.47; 95% CI, 0.25-0.90; P = 0.02) and associated with a reduced risk of dysplasia. However, Hp had no correlated with short-segment BE (OR = 1.11; 95% CI, 0.78-1.56; P = 0.57). In the present infected subgroup, Hp infection prevalence in BE was significantly lower than that in controls (OR = 0.69; 95% CI, 0.54-0.89; P = 0.005); however, this disappeared in the infection history subgroup (OR = 0.88; 95% CI, 0.43-1.78; P = 0.73). CONCLUSIONS Hp, especially the CagA-positive Hp strain, and BE are inversely related with considerable heterogeneity, which is likely mediated by a decrease in GERD prevalence, although this is not observed in the absence of current Hp infection.

Abstract
Although several studies have shown that each of the metabolic syndrome (MetS) components can be a risk factor for erosive esophagitis (EE), the association between MetS and EE is still a challenging subject, as studies about this association have shown inconsistent results. Therefore, this study was conducted to evaluate the association between MetS and EE. In this study, we followed the MOOSE protocol and the PRISMA guidelines for reporting the results. Web of Science (ISI), Cochrane Library (Cochrane Database of Systematic Reviews - CDSR), EMBASE, Scopus, Science Direct, PubMed/Medline, EBSCO, CINAHL, and Google Scholar search engine were searched for articles published until January 2021. Heterogeneity between studies was estimated by I2 index and Q test. All analyses were performed using Comprehensive Meta-Analysis Software. Finally, 12 studies entered the meta-analysis process after qualitative assessment. MetS was significantly associated with increased risk of EE (OR=1.488 [95 % CI: 1.352-1.638], P<0.001; Heterogeneity: I2= 55.57, P<0.001) in 12 studies with a sample size of 45285 (12825 cases and 29377 controls). In subgroup analysis based on types of studies (P=0.832), MetS diagnostic criteria (P=0.083) and quality of studies (P=0.612), no significant association was found. Sensitivity analysis showed that the overall estimation of effect size is still robust after omission of individual studies from the meta-analysis. Publication bias based on the Begg's test (P=0.945) and Egger's test (P=0.753) were not significant. MetS increases the risk of EE compared to control groups. Future studies should examine if MetS treatment reduces the risk of EE.

Abstract
BACKGROUND Conflicting results exist on the association between Helicobacter pylori infection and gastro-oesophageal reflux (GOR), and its complications, such as erosive oesophagitis (EO) and Barrett's oesophagus (BO). AIMS To explore the association of H. pylori infection with GOR symptoms and their complications METHODS: We searched Embase, PubMed, Web of Science and Scopus databases through December 2020 for relevant articles. Regarding the association between H. pylori and GOR symptoms (heartburn, regurgitation or reflux), we included observational studies comparing the prevalence of GOR symptoms between H. pylori-positive and -negative individuals. Concerning the association between H. pylori and complications of GOR, we included studies comparing the prevalence of EO or BO between H. pylori-positive and -negative individuals. RESULTS In total, 36 papers were eligible. Based on seven cross-sectional surveys, H. pylori infection was associated with a lower odds of GOR symptoms (odds ratio [OR] 0.74, 95% confidence interval [CI] 0.61-0.90). However, in four case-control studies, H. pylori infection was not associated with odds of GOR symptoms (OR 1.10, 95% CI 0.85-0.1.43). In 26 cross-sectional studies in patients with GOR symptoms, the OR for EO was 0.70 (95% CI 0.58-0.84) in H. pylori-positive vs -negative cases. Based on nine cross-sectional studies in subjects with GOR complications, no significant association was found between H. pylori infection and either endoscopically-diagnosed (OR 1.84, 95% CI 0.67-5.02) or histologically confirmed (OR 0.85, 95% CI 0.60-1.20) BO. CONCLUSIONS Helicobacter pylori infection appears to be associated with a decreased odds of GOR symptoms and EO. In contrast, H. pylori infection did not seem to affect the odds of BO in patients with GER complications.

Abstract
The gastrointestinal (GI) tract is home to a complex and dynamic community of microorganisms, comprising bacteria, archaea, viruses, yeast, and fungi. It is widely accepted that human health is shaped by these microbes and their collective microbial genome. This so-called second genome plays an important role in normal functioning of the host, contributing to processes involved in metabolism and immune modulation. Furthermore, the gut microbiota also is capable of generating energy and nutrients (eg, short-chain fatty acids and vitamins) that are otherwise inaccessible to the host and are essential for mucosal barrier homeostasis. In recent years, numerous studies have pointed toward microbial dysbiosis as a key driver in many GI conditions, including cancers. However, comprehensive mechanistic insights on how collectively gut microbes influence carcinogenesis remain limited. In addition to their role in carcinogenesis, the gut microbiota now has been shown to play a key role in influencing clinical outcomes to cancer immunotherapy, making them valuable targets in the treatment of cancer. It also is becoming apparent that, besides the gut microbiota's impact on therapeutic outcomes, cancer treatment may in turn influence GI microbiota composition. This review provides a comprehensive overview of microbial dysbiosis in GI cancers, specifically esophageal, gastric, and colorectal cancers, potential mechanisms of microbiota in carcinogenesis, and their implications in diagnostics and cancer treatment.

Abstract
Simple Summary Esophageal adenocarcinoma has a poor 5-year survival rate and is among the highest mortality cancers. Changes in the esophageal microbiome have been associated with cancer pathogenesis; however, the molecular mechanism remains obscure. This review article critically analyzes the molecular mechanisms through which microbiota may mediate the development and progression of esophageal adenocarcinoma and its precursors-gastroesophageal reflux disease and Barrett’s esophagus. It summarizes changes in esophageal microbiome composition in normal and pathologic states and subsequently discusses the role of altered microbiota in disease progression. The potential role of esophageal microbiota in protecting against the development of esophageal adenocarcinoma is also discussed. By doing so, this article highlights specific directions for future research developing microbiome-mediated therapeutics for esophageal adenocarcinoma. Abstract Esophageal adenocarcinoma (EAC) is associated with poor overall five-year survival. The incidence of esophageal cancer is on the rise, especially in Western societies, and the pathophysiologic mechanisms by which EAC develops are of extreme interest. Several studies have proposed that the esophageal microbiome may play an important role in the pathophysiology of EAC, as well as its precursors—gastroesophageal reflux disease (GERD) and Barrett’s esophagus (BE). Gastrointestinal microbiomes altered by inflammatory states have been shown to mediate tumorigenesis directly and are now being considered as novel targets for both cancer treatment and prevention. Elucidating molecular mechanisms through which the esophageal microbiome potentiates the development of GERD, BE, and EAC will provide a foundation on which new therapeutic targets can be developed. This review summarizes current findings that elucidate the molecular mechanisms by which microbiota promote the pathogenesis of GERD, BE, and EAC, revealing potential directions for additional research on the microbiome-mediated pathophysiology of EAC.

Abstract
Oesophageal cancer is a global health problem; in 2018 there were more than 572,000 people newly diagnosed with oesophageal cancer worldwide. There are two main histological subtypes of oesophageal cancer, oesophageal adenocarcinoma (EAC) and oesophageal squamous cell carcinoma (ESCC), and there has been a dramatic shift in its epidemiology. While the incidence of EAC and its precursor lesion, Barrett oesophagus, has increased in Western populations over the past four decades, the incidence of ESCC has declined in most parts of the world over the same period. ESCC still accounts for the vast majority of all oesophageal cancer cases diagnosed worldwide each year. Prognosis for patients with oesophageal cancer is strongly related to stage at diagnosis. As most patients are diagnosed with late-stage disease, overall 5-year survival for oesophageal cancer remains <20%. Knowledge of epidemiology and risk factors for oesophageal cancer is essential for public health and clinical decisions about risk stratification, screening and prevention. The goal of this Review is to establish the current epidemiology of oesophageal cancer, with a particular focus on the Western world and the increasing incidence of EAC and Barrett oesophagus.

Abstract
BACKGROUND AND AIMS The causes for the occurrence of goblet cells at the gastroesophageal junction (GEJ-GC) are unknown. The aim of our study was to compare the concurrent histologic changes of the stomach in (1) patients with GEJ-GC, but without Barrett's esophagus (BE) to those in (2) patients with BE and in (3) controls without GEJ-GC or BE. METHODS We used an electronic database of histopathologic records from 1.3 million individual patients, who underwent esophago-gastro-duodenoscopy (EGD) in 2009-2018. We compared the prevalence of Helicobacter pylori-positive gastritis (HpG), gastric intestinal metaplasia (G-IM), chronic inactive gastritis (CIG), and reactive gastropathy (RG) among the 3 patient groups, using odds ratios and their 95% confidence intervals. RESULTS Of all EGD patients, 4.0% harbored BE and 2.4% GEJ-GC. The average age of patients with GEJ-GC (60 ± 14) was significantly younger than the age of patients with BE (63 ± 12) and significantly older than the age of controls (55 ± 17). Female subjects were more common among GEJ-GC (54%) than BE (37%), but less common than among controls (63%). The 3 gastric histopathology changes associated with H. pylori were significantly more common in GEJ-GC than BE (for HpG 2.42, 2.29-2.56; for G-IM 1.82, 1.73-1.92; for CIG 1.31, 1.22-1.41). The corresponding differences between GEJ-GC and controls were less striking (for HpG 0.97, 0.93-1.01; for G-IM 1.15, 1.11-1.19; for CIG 0.90, 0.85-0.95). RG was slightly less common in GEJ-GC than BE (0.89, 0.86-0.92) and controls (0.94, 0.91-0.96). CONCLUSIONS With respect to its demographic and histopathologic features, GEJ-GC likely represents gastric intestinal metaplasia as opposed to BE and should prompt gastric intestinal metaplasia screening and management.

Abstract
INTRODUCTION An increase in the incidence of duodenal adenocarcinoma has been recently reported. However, little is known about the risk factors for duodenal adenocarcinoma, which are important for screening purposes. We, therefore, aimed to conduct a systematic review to identify risk factors for non-ampullary duodenal adenocarcinoma. METHODS A medical literature search was performed using electronic databases, including PubMed, Cochrane Library, Japan Medical Abstracts Society, and Web of Science. Studies that assessed the association between dietary habits, lifestyle behaviors, comorbidities, and non-ampullary duodenal adenocarcinoma were extracted. The Newcastle-Ottawa Scale was used to assess the risk of bias in individual studies, and the Grading of Recommendations, Assessment, Development, and Evaluations approach was used to assess the quality of evidence across studies included in this review. RESULTS Out of 1,244 screened articles, 10 were finally selected for qualitative synthesis. In the general population, no consistent risk factors were identified except for Helicobacter pylori positivity, which was considered a risk factor in 2 studies, but the quality of evidence was considered very low because of the high risk of bias. In patients with familial adenomatous polyposis (FAP), Spigelman stage IV at initial endoscopy was considered a consistent risk factor in 3 studies. CONCLUSIONS There are currently limited data regarding risk factors for non-ampullary duodenal adenocarcinoma, and no conclusive risk factors were identified in the general population. However, in patients with FAP, Spigelman stage IV was identified as a consistent risk factor. Further studies are needed to improve diagnosis and support effective clinical management of this malignancy.

Abstract
In the United States, the incidence of esophageal adenocarcinoma increased markedly since the 1970s with a recent stabilization. Despite evolving screening and surveillance strategies to diagnose, risk triage, and intervene in Barrett's esophagus patients to prevent esophageal adenocarcinoma, most cases present with advanced disease and poor resultant survival. Epidemiologic studies have identified the main risk factors for these conditions, including increasing age, male sex, white race, gastroesophageal reflux disease, abdominal obesity, cigarette smoking, and lack of infection with Helicobacter pylori. This review summarizes the current epidemiologic evidence with implications for screening and surveillance in Barrett's esophagus and esophageal adenocarcinoma.

Abstract
Background The epidemiology of esophageal cancer has changed dramatically over the past 4 decades in many Western populations. We aimed to understand the Hungarian epidemiologic trends of esophageal squamous cell cancer (SCC) and adenocarcinoma (AC). Methods We performed a cross-sectional study using data from esophageal cancer patients diagnosed between 1992 and 2018 at eight tertiary referral centers in four major cities of Hungary. We retrospectively identified cases in the electronic databases of each center and collected data on gender, age at diagnosis, year of diagnosis, specialty of the origin center, histological type, and localization of the tumor. Patients were grouped based on the two main histological types: AC or SCC. For statistical analysis, we used linear regression models, chi-square tests, and independent sample t tests. Results We extracted data on 3,283 patients with esophageal cancer. Of these, 2,632 were diagnosed with either of the two main histological types; 737 had AC and 1,895 SCC. There was no significant difference in the gender ratio of the patients between AC and SCC (80.1 vs 81.8% males, respectively; p = 0.261). The relative incidence of AC increased over the years (p < 0.001, b = 1.19 CI: 0.84–1.54). AC patients were older at diagnosis than SCC patients (64.37 ± 11.59 vs 60.30 ± 10.07 years, p < 0.001). The age of patients at the diagnosis of primary esophageal cancer increased over time (p < 0.001, R = 0.119). Conclusions The rapid increase in the relative incidence of AC and simultaneous decrease of the relative incidence of SCC suggest that this well-established Western phenomenon is also present in Hungary.

Abstract
Globally, a decreasing incidence of male esophageal squamous cell carcinoma (ESCC) has been observed in recent decades. We evaluated the determinants of esophageal distinct iodine-unstained lesions (DIULs), high-cancer-risk lesions and ESCC, among 3858 Japanese alcohol-dependent men (40-79 years) who underwent chromoendoscopic screening between 2003 and 2018. The initial screening detected DIULs ≥ 5 mm in 541 patients (dysplasia in 319 and SCC in 129) and multiple DIULs in 640. The detection rates for DIULs and chronic atrophic gastritis (CAG), pack-years, and the mean corpuscular volume (MCV) decreased over the course of the study period, while the detection of hiatal hernia and/or columnar-lined esophagus (HH/CLE) and the carriers of inactive heterozygous aldehyde dehydrogenase-2 (ALDH2, rs671) increased. Multiple logistic regression analyses showed that an older age, larger number of pack-years, smaller body mass index, larger MCV, presence of a slow-metabolizing alcohol dehydrogenase-1B genotype (rs1229984), presence of an inactive heterozygous ALDH2 genotype, and more advanced degree of CAG increased the odds ratios (ORs) for DIULs, while the 2008-2013 and 2014-2018 screening periods had lower ORs for DIULs than the 2003-2007 screening period. The presence of HH/CLE decreased the OR for multiple DIULs and was associated with a more proximal location of ESCC. In conclusion, the detection of DIULs in an alcohol-dependent population decreased between 2003 and 2018. In addition to reported determinants of ESCC, CAG and HH/CLE were associated with the risk of DIULs. Enigmatically, however, the decline in the detection of DIULs was not adequately explained by these factors and warrants further research.

Abstract
Early diagnosis and treatment of precancerous conditions of the esophagus is important to improve overall survival. Barrett's esophagus is the most common precancerous condition of the esophagus, and patients with Barrett's esophagus may develop tumor, maintain a precancerous condition, or recover. We analyzed miRNA and mRNA expression profiles from esophageal adenocarcinoma tissue and normal esophageal tissue in GEO database. We identified DEGs and DE_miRNAs from GEO2R online tools and used Venn software were used to detect the common DEGs and DE_miRNAs. We used Enrichr, an online bioinformatic tool, to perform the gene ontology (GO) analysis including BP, MF, and CC. We analyzed Mirdb.tsv, mirtarbase.tsv, and targetscan.tsv files and identified miRNA targeting genes. We analysed the data of RNA sequencing expression retrieved from the GEPIA website on the basis of thousands of samples from the GTEx projects and TCGA. There were three miRNA (has-mir-205, has-mir-203, has-mir-18) and one DEG (ENPP4) that were associated with the recovery from Barrett's esophagus. ENPP4 promotes coagulation, hemostasis, wound healing, and participates in neutrophil degranulation, neutrophil immune activation and its mediated immunity, contributes to the composition of some membrane particles and tertiary particles, and is related to nucleotide diphosphatase activity. ENPP4 overexpression was not conducive to Barrett's esophagus recovery.

Abstract
The human body is colonized by the microbial cells that are estimated to be as abundant as human cells, yet their genome is roughly 100 times the human genome, providing significantly more genetic diversity. The past decade has observed an explosion of interest in examining the existence of microbiota in the human body and understanding its role in various diseases including inflammatory bowel disease, neurologic diseases, cardiovascular disorders, and cancer. Many studies have demonstrated differential community composition between normal tissue and cancerous tissue, paving the way for investigations focused on deciphering the cause-and-effect relationships between specific microbes and initiation and progression of various cancers. Also, evolving are the strategies to alter tumor-associated dysbiosis and move it toward eubiosis with holistic approaches to change the entire neighborhood or to neutralize pathogenic strains. In this review, we discuss important pathogenic bacteria and the underlying mechanisms by which they affect cancer progression. We summarize key microbiota alterations observed in multiple tumor niches, their association with clinical stages, and their potential use in cancer diagnosis and management. Finally, we discuss microbiota-based therapeutic approaches.

Abstract
Osteoporosis (OP) and osteoporotic fractures (OFs) are common multifactorial and heterogenic disorders of increasing incidence. Helicobacter pylori (H.p.) colonizes the stomach approximately in half of the world's population, causes gastroduodenal diseases and is prevalent in numerous extra-digestive diseases known to be associated with OP/OF. The studies regarding relationship between H.p. infection (HPI) and OP/OFs are inconsistent. The current review summarizes the relevant literature on the potential role of HPI in OP, falls and OFs and highlights the reasons for controversies in the publications. In the first section, after a brief overview of HPI biological features, we analyze the studies evaluating the association of HPI and bone status. The second part includes data on the prevalence of OP/OFs in HPI-induced gastroduodenal diseases (peptic ulcer, chronic/atrophic gastritis and cancer) and the effects of acid-suppressive drugs. In the next section, we discuss the possible contribution of HPI-associated extra-digestive diseases and medications to OP/OF, focusing on conditions affecting both bone homeostasis and predisposing to falls. In the last section, we describe clinical implications of accumulated data on HPI as a co-factor of OP/OF and present a feasible five-step algorithm for OP/OF risk assessment and management in regard to HPI, emphasizing the importance of an integrative (but differentiated) holistic approach. Increased awareness about the consequences of HPI linked to OP/OF can aid early detection and management. Further research on the HPI-OP/OF relationship is needed to close current knowledge gaps and improve clinical management of both OP/OF and HPI-related disorders.

Abstract
Helicobacter pylori (H. pylori) infection has been associated with non-cardia adenocarcinoma in the stomach, while its role in gastric cardia adenocarcinoma (GCA) remains controversial. In addition, the association between H. pylori and the protective factors trefoil factor 1 (TFF1) and gastrokine 2 (GKN2) in gastroesophageal adenocarcinomas has not been fully investigated. Therefore, the mRNA and protein expression levels of TFF1 and GKN2 in GCA and distal gastric adenocarcinoma (DGA) were analyzed using quantitative PCR (qPCR) and immunohistochemistry, and the association with H. pylori infection was investigated. In addition, the effects of TFF1 and GKN2 overexpression on H. pylori-induced cells were investigated using western blot and reverse transcription-qPCR analysis. The comparative analysis of 16S rRNA-positive mRNA expression between GCA and DGA showed no statistically significant difference. However, the rate of the H. pylori vacuolating toxin A (VacA) genotype was significantly higher in GCA (49.2%) compared with that in DGA (26.9%; P<0.05). H. pylori infection downregulated the mRNA and protein expression levels of TFF1 and GKN2 in gastric tumor tissues, and the mRNA expression level of TFF1 and GKN2 was also markedly decreased in vitro. Furthermore, the cell proliferation varied in H. pylori total protein treatment group with the different doses. Notably, treatment with 20 µg/ml H. pylori total protein for 24 h resulted in the highest cellular proliferation rate. In addition, TFF1 and GKN2 overexpression inversely inhibited H. pylori-induced cell proliferation and upregulated NF-κB, tumor necrosis factor-α, IL-1β, IL-2, IL-4 and IL-6. The results of the present study indicate that H. pylori, particularly the VacA+ strain, plays an important role in GCA pathogenesis in high-risk areas of China, while TFF1/GKN2 inhibits H. pylori-induced cell proliferation and inflammation in GCA and DGA.

Abstract
The current barrier for investigation of Barrett esophagus (BE) in Asia is diagnostic standardization, which is a challenge to identify its true risk factors. This study aimed to investigate the prevalence, clinical characteristics and risk factors of BE in Vietnamese patients with upper gastrointestinal symptoms.A cross-sectional study was conducted on consecutive outpatients who underwent upper gastrointestinal endoscopy. Endoscopically suspected esophageal metaplasia (ESEM) which was clearly visible at least 1 cm above the gastroesophageal junction at endoscopy was taken biopsy. At least 1 biopsy per 2 cm in tongues of ESEM and 4 biopsies per 2 cm of circumferential ESEM were taken. The diagnostic criterion for BE was replacement of the normal squamous epithelial lining by columnar epithelium confirmed by histology.A total of 1947 patients were recruited. Forty-seven out of 58 patients with ESEM were histologically confirmed BE. The prevalences of BE and hiatal hernia (HH) were 2.4% (95% confidence interval [CI], 1.7-3.1%) and 2.3% (95% CI, 1.6-2.9%), respectively. Heartburn and/or regurgitation presented in only 61.7% (95% CI, 46.4-75.5%) of patients with BE. In multivariate analysis, the only 2 factors significantly associated with BE were HH (OR 7.53; 95% CI, 3.13-18.11; P < .001) and typical reflux symptom (OR 2.07; 95% CI, 1.12-3.83; P = .020).BE is not uncommon in Vietnamese patients with upper gastrointestinal symptoms. In addition, typical reflux symptoms and HH are the risk factors for BE in Vietnamese.

Abstract
BACKGROUND AND AIMS Few reports are available to reliably assess the ethnic distribution of Barrett metaplasia and reflux esophagitis. The present study served to analyze the joint influence of Helicobacter pylori infection and patient demographics on the diagnoses of Barrett metaplasia and reflux esophagitis. METHODS The Inform Diagnostics database is a national electronic repository of histopathologic records of patients distributed throughout the United States. In a case-control study of 52,096 cases with Barrett metaplasia, 189,235 cases with reflux esophagitis, and 152,322 controls without any signs or symptoms suggestive of gastroesophageal reflux disease, we assessed the influence of age, gender, ethnicity, and H. pylori status on occurrence of Barrett metaplasia or reflux esophagitis. RESULTS Barrett metaplasia was less common among East Asians (with odds ratio, 0.48; 95% confidence interval, 0.44-0.53) and Hispanics (0.60, 0.57-0.63) than other ethnic groups living in the United States. Reflux esophagitis was also less common among East Asians (0.86, 0.82-0.90), but more common among Hispanics (1.18, 1.14-1.21). Both types of esophageal disease were associated with a lower prevalence rates of gastric H. pylori infection than controls, with 0.48, 0.44-0.53 for Barrett metaplasia and 0.60, 0.57-0.63 for reflux esophagitis. The prevalence rates of gastric H. pylori and both esophageal diseases were greater in older than younger and male than female patients in all ethnic groups alike. CONCLUSIONS Gastric H. pylori infection, ethnicity, gender, and age all influence the occurrence of Barrett metaplasia, and reflux esophagitis.

Abstract
Non-erosive reflux disease (NERD) and esophageal adenocarcinoma (EAC) are often regarded as bookends in the gastroesophageal reflux disease spectrum. However, there is limited clinical evidence to support this disease paradigm while the underlying mechanisms of disease progression remain unclear. In this study, we used 16S rRNA sequencing and mass-spectrometer-based proteomics to characterize the esophageal microbiota and host mucosa proteome, respectively. A total of 70 participants from four patient groups (NERD, reflux esophagitis, Barrett’s esophagus, and EAC) and a control group were analyzed. Our results showed a unique NERD microbiota composition, distinct to control and other groups. We speculate that an increase in sulfate-reducing Proteobacteria and Bacteroidetes along with hydrogen producer Dorea are associated with a mechanistic role in visceral hypersensitivity. We also observed a distinct EAC microbiota consisting of a high abundance of lactic acid-producing bacteria (Staphylococcus, Lactobacillus, Bifidobacterium, and Streptococcus), which may contribute towards carcinogenesis through dysregulated lactate metabolism. This study suggests the close relationship between esophageal mucosal microbiota and the appearance of pathologies of this organ.

Helicobacter 2020; 25:e12688. [PMID: 32175626 DOI: 10.1111/hel.12688] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 02/18/2020] [Accepted: 02/20/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Helicobacter pylori (H. pylori) is associated with lower risks of Barrett's esophagus and esophageal adenocarcinoma, but whether H. pylori eradication increases the risk of these conditions is unknown. This study aimed to test the hypothesis that H. pylori eradication leads to gradually increased risks of Barrett's esophagus and esophageal adenocarcinoma over time, while esophageal squamous cell carcinoma was assessed for comparison reasons. MATERIAL AND METHODS This Swedish nationwide, population-based cohort study in 2005-2012 used data from the Swedish Prescribed Drug Registry to assess eradication treatment for H. pylori. Barrett's esophagus was identified from the Swedish Patient Registry, and esophageal adenocarcinoma and squamous cell carcinoma from the Swedish Cancer Registry. Standardized incidence ratios (SIRs) with 95% confidence intervals (CIs) were calculated by dividing the observed risk in the H. pylori eradication treatment cohort by the expected risk derived from the Swedish population of the same age, sex, and calendar period. RESULTS The cohort included 81 919 patients having had eradication treatment. For Barrett's esophagus (n = 178), the overall SIR was increased (SIR 3.67, 95% CI 3.15-4.25), but the SIRs slightly decreased over time after eradication treatment. For esophageal adenocarcinoma (n = 11), the overall SIR was 1.26 (95% CI 0.62-2.26), and the SIRs did not increase over time. The SIRs of esophageal squamous cell carcinoma (n = 10) were not influenced by eradication treatment. CONCLUSIONS This study did not provide any evidence of an increasing risk of Barrett's esophagus or esophageal adenocarcinoma (or esophageal squamous cell carcinoma) over time after eradication treatment for H. pylori.

Abstract
BACKGROUND The relationship between metabolic syndrome (MetS) and Barrett's esophagus (BE) is still a challenging issue, and inconsistent results have been reported in different studies. Therefore, this study was conducted to determine the relationship between MetS and BE. METHODS In this study, we followed the MOOSE protocol and results were reported according to the PRISMA guidelines. All study steps were performed independently by two authors. If necessary, the dispute was resolved by consultation with a third author. The search strategy is designed to find published studies. Comprehensive search was done in the following databases until July 2019: Cochrane Library, PubMed/Medline, Web of Science, Science Direct, EMBASE, Scopus, CINAHL, EBSCO, and Google Scholar search engine. All analyses were performed using Comprehensive Meta-Analysis Software Ver.2, while p-value lower than 0.05 was considered significant. RESULTS In 14 studies with a sample size of 108,416, MetS significantly increased the risk of BE (OR = 1.354; 95% CI: 1.145-1.600; P < 0.001; Heterogeneity: I2 = 81.95%; P < 0.001). Sensitivity analysis by omitting one study showed that overall estimates are still robust. Subgroup analysis was significant for continent (P < 0.001) and MetS diagnostic criteria (P = 0.043), but was not significant for variables of study type (P = 0.899), study setting (P = 0.115), control groups (P = 0.671) and quality of studies (P = 0.603). The Begg (P = 0.912) and Egger's (P = 0.094) tests were not significant; therefore, the publication bias did not play a role in the results. CONCLUSION MetS increases the risk of BE compared to control groups. The results of this study can help health practitioners by identifying a treatable risk factor for the most important risk factor for esophageal carcinoma (ie, BE). Future studies should examine whether treatment for MetS reduces the risk of BE.

Abstract
GOAL The goal of this study was to investigate the relationship between Helicobacter pylori (H. pylori) infection and short-segment and long-segment Barrett's esophagus (SSBE and LSBE). BACKGROUND H. pylori infection is reported to be inversely associated with Barrett's esophagus (BE) in western countries. However, the impact of BE segment length on the association between BE and H. pylori infection has scarcely been investigated. MATERIALS AND METHODS The study subjects were 41,065 asymptomatic Japanese individuals who took medical surveys between October 2010 and September 2017. Using this large database of healthy Japanese subjects, we investigated the association between H. pylori infection and SSBE/LSBE. We used multivariable logistic regression analysis to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Among the study subjects, 36,615 were eligible for the analysis. H. pylori seropositivity was significantly associated with a lower rate of LSBE (OR: 0.42; 95% CI: 0.16-0.91) and a higher rate of SSBE (OR: 1.66; 95% CI: 1.56-1.78) after multivariate adjustment. In the subgroup analysis, H. pylori seropositivity was significantly associated with a high rate of SSBE in subjects without reflux esophagitis (RE) (OR: 1.73; 95% CI: 1.61-1.85). However, H. pylori seropositivity was not associated with SSBE in subjects with RE (OR: 1.07; 95% CI: 0.84-1.37). CONCLUSION In a Japanese population, H. pylori infection was inversely associated with LSBE but significantly associated with SSBE only in subjects without RE. H. pylori may be a risk factor for SSBE, especially in individuals without RE.

Abstract
BACKGROUND AND AIM Current guidelines suggest screening at-risk groups of patients for Barrett's esophagus (BE), a precursor to esophageal cancer. Although BE and obstructive sleep apnea (OSA) have common risk factors, including elevated body mass index and gastroesophageal reflux disease (GERD), the relationship between these two conditions has not been well established. METHODS Retrospectively, all patients who had undergone a polysomnography and esophagogastroduodenoscopy at West Virginia University Hospital from 2013 to 2018 were identified and divided into groups on the basis of the presence or absence of OSA. Clinical course and procedure reports were reviewed to identify relevant variables. RESULTS One thousand ninety-one patients met inclusion criteria; 60.9% were female, and mean age of participants was 53.5 years. Univariate analysis revealed that male gender, age, diagnosis of OSA, severity of OSA, and a clinical diagnosis of GERD were associated with BE (P values < 0.05). Multiple logistic regression incorporating age, sex, clinical diagnosis of GERD, smoking history, body mass index, Helicobacter pylori status, and presence of hiatal hernia was utilized. Patients with OSA had an increased risk of BE than had those without OSA (P < 0.001, odds ratio 3.26 [1.72-6.85]). The risk increased with increasing severity of OSA, categorized in apnea-hypopnea index increments of 10. CONCLUSION Obstructive sleep apnea is associated with BE, a relationship that is independent of other known risk factors. Additionally, this risk increases with increasing severity of OSA. Future efforts should determine if patients with severe OSA need to be screened for BE due to its potential for causing esophageal cancer.

Abstract
OBJECTIVE Systematic reviews and meta-analyses have revealed the associations between H. pylori infection and various health outcomes. We aimed to evaluate the strength and breadth of evidence on the associations. DESIGN Umbrella review of systematic reviews and meta-analyses. SETTING No settings. PARTICIPANTS No patients involved. DATA SOURCES Embase, PubMed, Web of Science, Cochrane Library Databases, CNKI, VIP database and Wangfang database from inception to February 1, 2019. OUTCOMES MEASURES Diverse diseases (such as cancer and ischaemic heart disease). RESULTS Sixty articles reporting 88 unique outcomes met the eligible criteria. 74 unique outcomes had nominal significance (p<0.05). Of the outcomes with significance, 61 had harmful associations and 13 had beneficial associations. Furthermore, 73% (64) of the outcomes exhibited significant heterogeneity . Of the these meta-analyses, 32 had moderate to high heterogeneity (I2=50%-75%) and 24 had high heterogeneity (I2>75%). Moreover, 20% exhibited publication bias (p<0.1). In addition, 97% of the methodological qualities were rated 'critically low'. 36% of the evidence qualities of outcomes were rated 'low', 56% of the evidence qualities were rated 'very low' and 8% of the evidence qualities were rated 'moderate'. H. pylori infection may be associated with an increased risk of five diseases and a decreased risk of irritable bowel syndrome. CONCLUSION Although 60 meta-analyses explored 88 unique outcomes, moderate quality evidence only existed for six outcomes with statistical significance. H. pylori infection may be associated with a decreased risk of irritable bowel syndrome and an increased risk of hypertriglyceridemia, chronic cholecystitis and cholelithiasis, gestational diabetes mellitus, gastric cancer and systemic sclerosis.

[PMID: 31175364 DOI: 10.1093/dote/doz053] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 04/09/2019] [Accepted: 04/30/2019] [Indexed: 12/11/2022]
Abstract
There is a strong evidence that Helicobacter pylori infection is inversely associated with Barrett's esophagus. In a high-prevalence region of H. pylori, low rates of esophageal cancer and its precursor BE may indicate its preventive effect. The aim of this study is to determine the impact of H. pylori on characteristics of Barrett's esophagus. A total of 3317 outpatient upper endoscopy reports from 2013 to 2015 from an urban center in Azerbaijan from all patients with dyspepsia were retrospectively analyzed for patients with Barrett's esophagus. This was matched in a 1:2 ratio to age and gender matched control patients without Barrett's esophagus. The prevalence of H. pylori on Barrett's esophagus and the randomly selected control group were compared. There were 83 patients with BE and 167 control group cases. Biopsy-proven BE was diagnosed in 83 patients: 39 (47%) females, with mean age 43.1 ± 13.3 years. Of these, 13 (15.7%) had long segment and 70 (84.3%) had short segment Barrett's esophagus. A control group included 167 patients: 78 (46.7%) females, with mean age (45.8 ± 13.9). All patients were Caucasians. The rates of gastric inflammation, the presence of atrophy, and intestinal metaplasia in gastric specimens did not differ in patients versus controls. The prevalence of H. pylori was determined as 63.2% in male and 61.5 in female groups (odd ratio (OR) = 0.99 95%CI 0.97, 1.01; P = 0.22). Inflammation of gastric mucosa was strongly associated with the infection (67% vs. 33%; OR = 4.46 95% CI: 2.01, 9.92, P < 0.001). Atrophy was noted in majority of H. pylori-positive cases (OR = 1.43, 95% CI: 0.36, 5.65; P = 0.61). Gastric intestinal metaplasia was observed in 55.6% of H. pylori-positive patients and in 44.4% of negative individuals (OR = 0.74, 95% CI: 0.28, 1.94; P = 0.54). There was not a significant difference in the prevalence of HP in BE and control groups; 63.9% were positive for infection in BE cases and 61.7% of controls (OR = 1.10, 95% CI: 0.64, 1.90; P = 0.74). We found that neither presence of erosive esophagitis, length of BE nor dysplasia (45.5% of H. pylori-positive group, whereas 54.5%) was associated with the presence of the H. pylori infection (Table 1). In a predominantly Caucasian nation with a high prevalence of H. pylori gastritis, the presence of H. pylori was not inversely associated with the presence of Barrett's esophagus. These data challenge the mechanistic implications of this association.

Abstract
This review covers recent publications investigating the relationship between Helicobacter pylori infection and gastroesophageal reflux disease, Barrett's esophagus, eosinophilic esophagitis, peptic ulcer disease (PUD), H pylori gastritis, and functional dyspepsia. In the area of gastroesophageal reflux disease, new data suggest that reflux may have a role in the transmission of H pylori infection. In addition to several observational studies, data on alterations in esophageal physiology in patients with H pylori infection are presented. Further evidence for the inverse relationship between H pylori infection and Barrett's esophagus is available in the form of a meta-analysis from the North American Barrett's and Esophageal Carcinoma Consortium. The relationship between H pylori infection and eosinophilic esophagitis remains uncertain. Although new data do not indicate a significantly lower prevalence of H pylori among patients with eosinophilic esophagitis, a meta-analysis showed a 37% reduced risk of eosinophilic esophagitis among H pylori-infected patients. Novel data are presented on the genetic variability of bacterial virulence factors and their relationship with PUD. We also report data on plasma biomarkers, which may detect progression to gastric cancer in H pylori-associated PUD. A new meta-analysis was published, which assessed the risk of PUD in low-dose aspirin users with H pylori infection. Finally, we report on the ongoing attempts to stratify patients with gastritis using endoscopic methods when compared to standard biopsy examination.

Abstract
BACKGROUND AND AIM Barrett's esophagus and colorectal polyps have several overlapping risk factors. Whereas several reports in Western countries have indicated a close relationship between Barrett's esophagus and colorectal polyps, the relationship between these two diseases remains unclear in Japan. This study was performed to determine whether the prevalence of Barrett's esophagus is related to that of colorectal polyps in Japanese patients. METHODS The present retrospective chart review included 1582 Japanese patients who underwent both total colonoscopy and esophagogastroduodenoscopy from January 2010 to December 2016. The data on colorectal polyps and Barrett's esophagus were obtained from the endoscopic findings. The medical record of each patient was checked for age, sex, body mass index, smoking, alcohol drinking, use of acid suppression agents, and comorbidities including a history of diabetes, ischemic heart disease, gastroesophageal reflux disease, hiatal hernia, and Helicobacter pylori infection. RESULTS Colorectal polyps were detected in 789 of the 1582 patients (49.9%). Barrett's esophagus was detected in 233 patients (14.7%), and most cases of Barrett's esophagus (n = 229) were classified as short-segment Barrett's esophagus. Colorectal polyps were more frequent in patients with than without Barrett's esophagus (odds ratio, 1.79; 95% confidence interval, 1.31-2.46; P < 0.001). In addition to Barrett's esophagus, the data indicated that old age, male sex, obesity, smoking, alcohol drinking, diabetes mellitus, and ischemic heart disease were independent risk factors for colorectal polyps. CONCLUSIONS The present study revealed the correlation between the prevalence of Barrett's esophagus and colorectal polyps in Japanese patients.

Abstract
BACKGROUND In recent decades, the prevalence of gastroesophageal reflux disease (GERD) and obesity has been increasing while Helicobacter pylori infection has been decreasing. OBJECTIVE To evaluate if H. pylori treatment, excess body weight and other anthropometric measurements are associated with incident erosive esophagitis, as a secondary objective of a trial which tested the efficacy of treatment of H. pylori on the symptoms of functional dyspepsia. SUBJECTS/METHODS Upper gastrointestinal endoscopy and anthropometric assessments were performed, at baseline and after 12 months, in H. pylori positive patients with functional dyspepsia who had no baseline reflux symptoms or esophagitis. Patients were randomly assigned to receive omeprazole, amoxicillin, and clarithromycin (antibiotic group; n = 201) or omeprazole plus placebo (control group; n = 203). The primary outcome was the incidence of esophagitis 12 months after randomization, according to treatment groups, and the association of BMI and other anthropometric measurements. RESULTS Four hundred and four patients were included (mean age, 46.1 years; 78.7% women). The 12-month follow-up endoscopic esophagitis rates for the antibiotic and control groups were 10.9% (22/201) and 9.4% (19/203), respectively (p = 0.60). The number needed to harm was 67. Baseline anthropometric measurements were performed in 94% (380/404) of patients. The 12-month follow-up esophagitis rates for overweight and normal body weight patients were 13.6% (29/213) and 6.0% (10/167), respectively (p = 0.015); rates for patients with and without increased baseline waist circumference were 15.4% (24/156) and 6.7% (15/224), respectively (p = 0.006). Following logistic regression, only the combination of increased baseline body mass index and waist, but not H. pylori treatment, was independently associated with new-onset esophagitis (OR 2.88; 95% CI: 1.28-6.45). CONCLUSIONS Excess body weight and concomitant increased waist circumference, but not H. pylori treatment, predicts new-onset esophagitis.

Abstract
Barrett oesophagus (BE), the only known histological precursor of oesophageal adenocarcinoma (EAC), is a condition in which the squamous epithelium of the oesophagus is replaced by columnar epithelium as an adaptive response to gastro-oesophageal reflux. EAC has one of the fastest rising incidences of cancers in Western countries and has a dismal prognosis. BE is usually detected during endoscopic examination, and diagnosis is confirmed by the histological presence of intestinal metaplasia. Advances in genomics and transcriptomics have improved our understanding of the pathogenesis and malignant progression of intestinal metaplasia. As the majority of EAC cases are diagnosed in individuals without a known history of BE, screening for BE could potentially decrease disease-related mortality. Owing to the pre-malignant nature of BE, endoscopic surveillance of patients with BE is imperative for early detection and treatment of dysplasia to prevent further progression to invasive EAC. Developments in endoscopic therapy have resulted in a major shift in the treatment of patients with BE who have dysplasia or early EAC, from surgical resection to endoscopic resection and ablation. In addition to symptom control by optimization of lifestyle and pharmacological therapy with proton pump inhibitors, chemopreventive strategies based on NSAIDs and statins are currently being investigated for BE management.

Abstract
Esophageal cancer (EC) is an extremely aggressive cancer with one of the highest mortality rates. The cancer is generally only diagnosed at the later stages and has a poor 5-year survival rate due to the limited treatment options. China and South Africa are two countries with a very high prevalence rate of EC. EC rates in South Africa have been on the increase, and esophageal squamous cell carcinoma is the predominant subtype and a primary cause of cancer-related deaths in the black and male mixed ancestry populations in South Africa. The incidence of EC is highest in the Eastern Cape Province, especially in the rural areas such as the Transkei, where the consumption of foods contaminated with Fusarium verticillioides is thought to play a major contributing role to the incidence of EC. China is responsible for almost half of all new cases of EC globally. In China, the prevalence of EC varies greatly. However, the two main areas of high prevalence are the southern Taihang Mountain area (Linxian, Henan Province) and the north Jiangsu area. In both countries, environmental toxins play a major role in increasing the chance that an individual will develop EC. These associative factors include tobacco use, alcohol consumption, nutritional deficiencies and exposure to environmental toxins. However, genetic polymorphisms also play a role in predisposing individuals to EC. These include single-nucleotide polymorphisms that can be found in both protein-coding genes and in non-coding sequences such as miRNAs. The aim of this review is to summarize the contribution of genetic polymorphisms to EC in South Africa and to compare and contrast this to the genetic polymorphisms observed in EC in the most comprehensively studied population group, the Chinese.

Abstract
Esophageal adenocarcinoma carries a very poor prognosis. For this reason, it is critical to have cost-effective surveillance and prevention strategies and early and accurate diagnosis, as well as evidence-based treatment guidelines. Barrett’s esophagus is the most important precursor lesion for esophageal adenocarcinoma, which follows a defined metaplasia–dysplasia–carcinoma sequence. Accurate recognition of dysplasia in Barrett’s esophagus is crucial due to its pivotal prognostic value. For early-stage esophageal adenocarcinoma, depth of submucosal invasion is a key prognostic factor. Our systematic review of all published data demonstrates a “rule of doubling” for the frequency of lymph node metastases: tumor invasion into each progressively deeper third of submucosal layer corresponds with a twofold increase in the risk of nodal metastases (9.9% in the superficial third of submucosa (sm1) group, 22.0% in the middle third of submucosa (sm2) group, and 40.7% in deep third of submucosa (sm3) group). Other important risk factors include lymphovascular invasion, tumor differentiation, and the recently reported tumor budding. In this review, we provide a concise update on the histopathological features, ancillary studies, molecular signatures, and surveillance/management guidelines along the natural history from Barrett’s esophagus to early stage invasive adenocarcinoma for practicing pathologists.
