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.

Relationship between gluten availability and celiac disease prevalence: A geo-epidemiologic systematic review. J Gastroenterol Hepatol 2023; 38:1695-1709. [PMID: 37332011 DOI: 10.1111/jgh.16260] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 05/04/2023] [Accepted: 05/31/2023] [Indexed: 06/20/2023]
Abstract
Celiac disease is a global disease requiring genetic susceptibility and gluten exposure to trigger immune-mediated enteropathy. The effect of the degree of gluten-containing grain availability on celiac disease prevalence is unknown. Our objective was to compare country-based gluten availability to celiac prevalence using a systematic literature review. We searched MEDLINE, Embase, Cochrane, and Scopus until May 2021. We included population-based serum screening with confirmatory testing (second serological study or small intestine biopsy) and excluded specific, high-risk, or referral populations. We determined country-specific gluten availability using the United Nations food balance for wheat, barley, and rye. Human leukocyte antigen (HLA) frequencies were obtained from allelefrequencies.net. The primary outcome was association between gluten-containing grain availability and celiac disease prevalence. Generalized linear mixed models method with Poisson's link was used for analysis. We identified 5641 articles and included 120 studies on 427 146 subjects from 41 countries. Celiac disease prevalence was 0-3.1%, median 0.75% (interquartile range 0.35, 1.22). Median wheat supply was 246 g/capita/day (interquartile range 214.8, 360.7). The risk ratio (RR) for wheat availability on celiac disease was 1.002 (95% confidence interval [CI]: 1.0001, 1.004, P = 0.036). A protective association was seen with barley, RR 0.973 (95% CI: 0.956, 0.99, P = 0.003), and rye, RR 0.989 (95% CI: 0.982, 0.997, P = 0.006). The RR for gross domestic product on celiac disease prevalence was 1.009 (95% CI: 1.005, 1.014, P < 0.001). The RR for HLA-DQ2 was 0.982 (95% CI: 0.979, 0.986, P < 0.001), and that for HLA-DQ8 was 0.957 (95% CI: 0.950, 0.964, P < 0.001). In this geo-epidemiologic study, gluten-containing grain availability showed mixed associations with celiac disease prevalence.

BMC Pediatr 2023; 23:116. [PMID: 36890496 PMCID: PMC9993645 DOI: 10.1186/s12887-023-03934-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 02/25/2023] [Indexed: 03/10/2023] Open
Abstract
BACKGROUND Evidence shows the increase of anti-tissue transglutaminase (tTG) levels in various conditions, including infectious agents, independently of celiac disease (CD). The aim of this study was to investigate the effect of helicobacter pylori (H.pylori) infection eradication on serum level of tTG in children with CD. METHODS This study was conducted on children aged 2 to 18 who referred to reference hospitals for diagnosis of CD. After upper endoscopy and biopsy to confirm CD and H.pylori infection, the children were divided into three groups (including group one: 16 CD patients with positive H. pylori; group two: 16 non-CD patients with positive H. pylori; and group three: 56 CD patients with negative H. pylori), respectively. The tTG level in study groups were compared after the eradication of H.pylori. RESULTS The mean age of the subjects in the group one, two, and three was 9.7 ± 3.33, 11.8 ± 3.14, and 7.6 ± 3.32 years, respectively. Our results showed that in group one, mean tTG increased after eradication of H.pylori infection, however, these changes were not significant (182.43 vs. 157.18, P = 0.121). In the second group, although unlike the first group, mean tTG decreased after eradication of the infection, but still these changes were not significant (9.56 vs. 22.18, P = 0.449). Furthermore, at the baseline level, the mean tTG in the group three was closer to the mean tTG in the first group. CONCLUSION Our findings showed that the eradication of H.pylori infection does not have a significant effect on tTG levels in children with and without CD.

Abstract
OBJECTIVE To investigate why certain at-risk individuals develop celiac disease (CD), we examined the association of proton pump inhibitors (PPI), histamine-2 receptor antagonists (H2RAs), and antibiotic prescriptions in the first 6 months of life with an early childhood diagnosis of CD. STUDY DESIGN A retrospective cohort study was performed using the Military Healthcare System database. Children with a birth record from October 1, 2001, to September 30, 2013, were identified. Outpatient prescription records were queried for antibiotic, PPI, and H2RA prescriptions in the first 6 months of life. Cox proportional hazards regression was used to calculate the hazard ratio (HR) of developing CD based on medication exposure. International Classification of Diseases, Ninth Revision, Clinical Modification codes identified children with an outpatient visit for CD. RESULTS There were 968 524 children who met the inclusion criteria with 1704 cases of CD in this group. The median follow-up for the cohort was approximately 4.5 years. PPIs (HR, 2.23; 95% CI, 1.76-2.83), H2RAs (HR, 1.94; 95% CI, 1.67-2.26), and antibiotics (HR, 1.14; 95% CI, 1.02-1.28) were all associated with an increased hazard of CD. CONCLUSIONS There is an increased risk of developing CD if antibiotics, PPIs and H2RAs are prescribed in the first 6 months of life. Our study highlights modifiable factors, such as medication stewardship, that may change the childhood risk of CD.

Abstract
Humans are supra-organisms co-evolved with microbial communities (Prokaryotic and Eukaryotic), named the microbiome. These microbiomes supply essential ecosystem services that play critical roles in human health. A loss of indigenous microbes through modern lifestyles leads to microbial extinctions, associated with many diseases and epidemics. This narrative review conforms a complete guide to the human holobiont-comprising the host and all its symbiont populations- summarizes the latest and most significant research findings in human microbiome. It pretends to be a comprehensive resource in the field, describing all human body niches and their dominant microbial taxa while discussing common perturbations on microbial homeostasis, impacts of urbanization and restoration and humanitarian efforts to preserve good microbes from extinction.

Abstract
Investigation of gene-environment cross talk through epigenetic modifications led to better understanding of the number of complex diseases. Clinical heterogeneity and differential treatment response often contributed by the epigenetic signatures which could be personal. DNA methylation at CpG islands presents a critical nuclear process as a result of gene-environment interactions. These CpG islands are frequently present near the promoter sequence of genes and get differentially methylated under specific environmental conditions. Technical advancements facilitate in high throughput screening of differentially methylated CpG islands. Recent epigenetic studies unraveled several CD susceptibility genes expressed in peripheral blood lymphocytes (PBLs), duodenal mucosa, lamina and epithelial cells that are influenced by differentially methylated CpG islands. Here we highlighted these susceptibility genes; classify these genes based on cellular functions and tissue of expression. We further discussed how these genes interacts with each other to influence critical pathways like NF-κB signaling pathway, IL-17 signaling cascade, RIG-I like receptor signaling pathway, NOD-like receptor pathways among several others. This review also shed light on how gut microbiota may lead to the differential methylation of CpG islands of CD susceptibility genes. Large scale epigenetic studies followed by estimation of heritability of these CpG methylation and polygenic risk score estimation of these genes would prioritize potentially druggable targets for better therapeutics. In vivo studies are warranted to unravel further cellular responses to CpG methylation.

Abstract
Celiac disease (CD) is characterized by a proinflammatory state associated with the production of reactive oxygen species, i.e., a condition of oxidative stress. In this study, we tested the hypothesis that the inherited deficiency of glucose-6-phosphate dehydrogenase (G6PD), by causing impaired antioxidant defense, may increase the risk of CD. METHODS A retrospective monocentric case-control study was performed using the clinical records of 8338 outpatients (64.6% women) scheduled for upper endoscopy between 2002 and 2021 in Northern Sardinia. Overall, 627 were found to have CD (7.5%), and 1027 resulted to be G6PD-deficiency carriers (12.3%). Since randomization was impractical, the potential covariates imbalance between cases and controls was minimized using a 1:2 propensity-score-matched (PSM) analysis. RESULTS Overall, G6PD deficiency was associated with increased risk of CD (odds ratio (OR) 1.50; 95% confidence interval (CI) 1.19-1.90). The PSM procedure identified 1027 G6PD-deficient and 2054 normal patients. Logistic regression including the propensity score detected for G6PD deficiency an OR of 1.48 (95%CI 1.13-1.95; p = 0.004). CONCLUSIONS Our findings show that the enzyme defect was significantly and positively associated with CD, in line with the pro-oxidant impact of the enzyme defect observed in animal models and humans.

Abstract
BACKGROUND Research on celiac disease (CD) in northwest China is still in its infancy. At present, large-sample data on the epidemiological, clinical, and pathological characteristics of CD are limited.
AIM To investigate the epidemiological, clinical, and pathological characteristics of CD in northwest China.
METHODS The clinical data of 2884 patients with gastrointestinal (GI) symptoms were retrospectively analyzed. Total immunoglobulin A (IgA) and anti-tissue transglutaminase (tTG) IgA levels were examined in all patients. Gastroscopy and colonoscopy were performed in patients with positive anti-tTG IgA and deficient total IgA levels. Atrophy of the duodenal and ileal villi was examined and histopathological examinations were performed. The modified Marsh–Oberhuber classification system was used to grade villous atrophy in the duodenum or distal ileum. The patients’ Helicobacter pylori (H. pylori) infection status was compared in terms of clinical presentation and Marsh grade. Statistical analyses were performed using the t-test or chi-square test.
RESULTS Among the 2884 patients, 73 were positive for serum anti-tTG IgA, and 50 were diagnosed with CD. The CD detection rate was significantly higher in Kazakhs (4.39%) than in Uyghurs (2.19%), Huis (0.71%), and Hans (0.55%). The main symptoms of CD were chronic diarrhea, anorexia, anemia, fatigue, weight loss, sleep disorders, osteopenia, and osteoporosis. The body mass index of patients with CD was significantly lower than that of patients without CD. A total of 69 patients with positive serum anti-tTG IgA and two patients with deficient total IgA levels underwent GI endoscopy. Endoscopy revealed crypt hyperplasia and/or duodenal villous atrophy, mainly manifested as nodular mucosal atrophy, grooves, and fissures. The difference in H. pylori infection rates was not statistically significant between CD and non-CD patients but was significantly different among CD patients with different Marsh grades.
CONCLUSION Among the patients with GI symptoms in northwestern China, the prevalence of CD was more in the Uyghur and Kazakh populations. H. pylori infection may be associated with CD severity.

Abstract
BACKGROUND The prevalence of celiac disease in the general population is mainly unknown in most of sub-Saharan African countries. The aim of this study was to determine the incidence of celiac disease autoimmunity (CDA) and its associations with latent Mycobacterium tuberculosis (LMTB) and Helicobacter pylori (HP) infections in Ethiopian children aged 4 years in an HLA genotyped cohort study. METHODS Of 1,389 recruited children between 2018 and 2022, 1,046 (75.3%) had been screened at least twice for celiac disease between the ages of 2 and 4 years using a tissue transglutaminase autoantibody (tTGA) ELISA kit. Tissue TGA-positive children were retested using radio-binding assays. CDA was defined as persistent-confirmed tTGA positivity in two consecutive samples. Associations of CDA with LMTB and HP were tested in a subpopulation of 752 children born to mothers who were previously tested for LMTB with IFN-γ and anti-HP antibodies in samples collected at a mean age of 49.3 ± 5.3 months. RESULTS Screening detected 38 out of 1,046 (3.6%) IgA-tTGA-positive children. Ten (1.0%) were confirmed to be positive, with six (0.6%) children diagnosed with CDA. The incidence of CDA at 4 years of age was 1.2 per 1,000 person-years. LMTB was found in 4 of 6 (66.7%) mothers with CDA children compared with 340 of 734 (46.3%) mothers of children without CDA (p = 0.424), while HP was found in 3 of 6 (50.0%) CDA children compared with 315 of 746 (42.2%) children without CDA (p = 0.702). CONCLUSION The incidence of CDA in Ethiopian children is lower than the pooled global incidence. Neither LMTB nor HP infections are associated with CD in Ethiopian children.

Between 2008 and 2020, 1.5 million patients with endoscopic biopsies of the gastroduodenal mucosa were extracted from a database. LyG diagnoses were reviewed to collect detailed information regarding its topographic distribution within the stomach. In a large subgroup of 400 000 patients, tissue samples from the colon were also available. RESULTS Of 1 481 336 patients, 341 had LyG with Hp and 2697 had Hp-negative LyG (with an overall prevalence of 0.21%). In patients with Hp-negative LyG, 450 (17%) had corpus-predominant LyG, 1068 antrum-predominant LyG (40%), and 1179 pangastric LyG (44%). LyG was more common in males and in subjects aged 50-70 years. There was no significant ethnic variation. Anaemia, diarrhoea, and weight loss were more common in patients with than without LyG. In 35% and 19% of patients, LyG was associated with CD and MC, respectively. All 72 patients with Hp-positive LyG and 280 of 310 patients with Hp-negative LyG with follow-up biopsies became free of LyG within a year. CONCLUSIONS Most cases of LyG may represent a self-limited expression, frequently associated with other GI conditions, such as Hp infection, CD, and MC. In most patients, LyG is likely to resolve within a year after its initial diagnosis.

Abstract
Celiac disease (CD) is a chronic immune-mediated intestinal disease with genetic susceptibility. It is characterized by inflammatory damage to the small intestine after ingestion of cereals and products containing gluten protein. In recent years, the global prevalence rate of CD has been approximately 1%, and is gradually increasing. CD patients adhere to a gluten-free diet (GFD) throughout their entire life. However, it is difficult to adhere strictly to a GFD. Untreated CD may be accompanied by gastrointestinal symptoms, such as diarrhea, abdominal pain, and extraintestinal symptoms caused by secondary malnutrition. Many studies have suggested that CD is associated with intestinal tumors such as enteropathy-associated T-cell lymphoma (EATL), small bowel cancer (SBC), and colorectal cancer. In this study, we reviewed related studies published in the literature to provide a reference for the prevention and treatment of intestinal tumors in patients with CD. Compared with the general population, CD patients had a high total risk of SBC and EATL, but not colorectal cancer. The protective effect of GFD on CD-related malignancies is controversial. Further studies are needed to confirm whether GFD treatment can reduce the risk of intestinal neoplasms in CD.

Abstract
Infection with Helicobacter pylori (H. pylori) is necessary but not sufficient for the development of gastric cancer, the third leading cause of cancer death globally. H. pylori infection affects over half of people globally; however, it does not affect populations uniformly. H. pylori infection rates are declining in western industrialized countries but are plateauing in developing and newly industrialized countries where gastric cancer is most prevalent. Despite H. pylori infection being the primary causative agent for gastric cancer, H. pylori infection can also cause other effects, detrimental or beneficial, throughout an individual's life, with the beneficial effects often being seen in childhood and the deleterious effects in adulthood. H. pylori is an ancient bacterium and its likelihood of affecting disease or health is dependent on both human and bacterial genetics that have co-evolved over millennia. In this review, we focus on the impact of infection and its genetic bases in different populations and diseases throughout an individual's lifespan, highlighting the benefits of individualized treatment and argue that universal eradication of H. pylori in its host may cause more harm than good for those infected with H. pylori.

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 Low serum titer of anti-tissue transglutaminase (tTG) has been described in various conditions without any evidence of celiac disease (CD). Infectious agents have been suggested to trigger autoimmunity and promote the production of anti-tTG. The aim of this study was to investigate if there is a link between a positive celiac serology and concomitant Helicobacter pylori infection in children. METHODS The data of 178 pediatric patients who underwent upper gastrointestinal endoscopy due to positive celiac serology were compiled. The patients whose histopathologic findings were not consistent with CD were followed on gluten-containing diet. The changes in the serum level of anti-tTG IgA on the follow-up were compared between H. pylori-infected and noninfected patients after the eradication of H. pylori. RESULTS Of 155 patients who met the inclusion criteria, 119 (group 1) were diagnosed as CD, and duodenal histopathology of the remaining 36 children (group 2) was not compatible with CD. In group 2, 11 out of 36 (30.5%) patients were infected with H. pylori. After the eradication of H. pylori, anti-tTG IgA level either decreased or dropped below cutoff value in 9/11 (81%) patients while it was 20% in those who were not infected with H. pylori in the 6th month of the follow-up (p = 0.001). CONCLUSION Our results suggest that H. pylori infection may be the cause of false or transient positive celiac serology. Thus, a positive celiac serology should be carefully interpreted in the presence of H. pylori infection before confirming the diagnosis of this life-long disease.

Abstract
Histamine intolerance (HIT) is assumed to be due to a deficiency of the gastrointestinal (GI) enzyme diamine oxidase (DAO) and, therefore, the food component histamine not being degraded and/or absorbed properly within the GI tract. Involvement of the GI mucosa in various disorders and diseases, several with unknown origin, and the effects of some medications seem to reduce gastrointestinal DAO activity. HIT causes variable, functional, nonspecific, non-allergic GI and extra-intestinal complaints. Usually, evaluation for HIT is not included in differential diagnoses of patients with unexplained, functional GI complaints or in the here-listed disorders and diseases. The clinical diagnosis of HIT is challenging, and the thorough anamnesis of all HIT-linked complaints, using a standardized questionnaire, is the mainstay of HIT diagnosis. So far, DAO values in serum have not been established to correlate with DAO activity in the gut, but the diagnosis of HIT may be supported with determination of a low serum DAO value. A targeted dietary intervention, consisting of a histamine-reduced diet and/or supplementation with oral DAO capsules, is helpful to reduce HIT-related symptoms. This manuscript will present why histamine should also be taken into account in the differential diagnoses of patients with various diseases and disorders of unknown origin, but with association to functional gastrointestinal complaints. In this review, we discuss currently increasing evidence that HIT is primarily a gastrointestinal disorder and that it originates in the gut.

A systematic review and meta-analysis for association of Helicobacter pylori colonization and celiac disease. PLoS One 2021; 16:e0241156. [PMID: 33657108 PMCID: PMC7928511 DOI: 10.1371/journal.pone.0241156] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2020] [Accepted: 02/12/2021] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND AND OBJECTIVES Based on some previous observational studies, there is a theory that suggests a potential relationship between Helicobacter pylori (H. pylori) colonization and celiac disease (CeD); however, the type of this relationship is still controversial. Therefore, we aimed to conduct a systematic review and meta-analysis to explore all related primary studies to find any possible association between CeD and human H. pylori colonization. DATA SOURCES Studies were systematically searched and collected from four databases and different types of gray literature to cover all available evidence. After screening, the quality and risk of bias assessment of the selected articles were evaluated. SYNTHESIS METHODS Meta-analysis calculated pooled odds ratio (OR) on the extracted data. Furthermore, heterogeneity, sensitivity, subgroups, and publication bias analyses were assessed. RESULTS Twenty-six studies were included in this systematic review, with a total of 6001 cases and 135512 control people. The results of meta-analysis on 26 studies showed a significant and negative association between H. pylori colonization and CeD (pooled OR = 0.56; 95% CI = 0.45-0.70; P < 0.001), with no publication bias (P = 0.825). The L'Abbé plots also showed a trend of having more H. pylori colonization in the control group. Among subgroups, ORs were notably different only when the data were stratified by continents or risk of bias; however, subgroup analysis could not determine the source of heterogeneity. CONCLUSIONS According to the meta-analysis, this negative association might imply a mild protective role of H. pylori against celiac disease. Although this negative association is not strong, it is statistically significant and should be further considered. Further investigations in both molecular and clinic fields with proper methodology and more detailed information are needed to discover more evidence and underlying mechanisms to clear the interactive aspects of H. pylori colonization in CeD patients.

Abstract
In 2016, the European and North American Societies for Pediatric Gastroenterology, Hepatology, and Nutrition updated guidelines for management of Helicobacter pylori in children, adjusting the previous diagnostic and therapeutic approaches in response to changing epidemiology and antibiotic resistance patterns. In this study, we assessed knowledge, practice habits of H. pylori management, and adherence to new guideline recommendations among one state's community pediatric providers. The majority of the surveyed community pediatric providers are not following the new pediatric guidelines for H. pylori management. An evidence-practice gap for diagnosis and treatment of H. pylori disease can lead to poor resource utilization, inadequate antibiotic usage, increased antibiotic resistance, and prolonged symptoms in patients. By understanding pediatric provider practices, pediatric gastroenterologists can assist in addressing the gap through development of educational interventions for community pediatric providers.

Abstract
OBJECTIVES Data regarding Helicobacter pylori (Hp) infection frequency in concurrent celiac disease (CD) and type 1 diabetes mellitus (T1DM) (CD + T1DM) are anecdotal. This study aimed to evaluate the association between Hp and concomitant CD + T1DM in children. METHODS In this 2-center, case-control study, children who underwent esophago-gastro-duodenoscopy (EGD) were studied. CD diagnosis was established by favorable histology and serology. Hp infection was confirmed by both histology and the rapid urease test. Patients were divided into 3 groups as CD only (CDo), CD + T1DM, and non-CD children who underwent endoscopy as controls. RESULTS Among the 1,431 EGDs performed, 783 cases were eligible. Overall, 215 cases had CDo (mean age: 9.12 ± 4.18 years, 58.1% girls), 63 cases had CD + T1DM (mean age: 9.29 ± 4.46 years, 50.8% girls), and 505 cases were controls (mean age: 9.69 ± 4.52 years, 56.6% girls). Hp infection rate was significantly lower in CD + T1DM group (controls: 49.7% vs. CDo: 32.1% vs. CD + T1DM: 20.6%, p < 0.01). After adjustment for age, gender, and socioeconomic status, the Hp infection rate was still significantly low (adjusted odds ratio [aOR]: 1.57, 95% confidence interval (CI): 1.35-1.83, p < 0.01). A difference in Hp infection rate between controls and CDo group (aOR: 1.43, 95% CI: 1.09-2.12, p < 0.05), and between CDo and CD + T1DM (aOR: 0.89, 95% CI: 0.65-1.54, p < 0.05) group was significant. The severity of duodenal lesions and the presence of Hp infection were not correlated in all celiac children (r: 0.113, p > 0.05). CONCLUSION The frequency of Hp infection was significantly lower in CD + T1DM children, compared to the CDo group and the controls.

Abstract
The incidence of celiac disease is increasing, partly because of improved recognition of, and testing for, the disease. The rise in incidence is also due to a real increase of this immune-based disorder, independent of disease detection. The reasons for this true rise in recent decades are unknown but may be related to environmental factors that may promote loss of tolerance to dietary gluten. Strategies to reduce the development of celiac disease have not been proven successful in randomized trials, but the quantity of early-life gluten exposure has been a major focus of prevention efforts. The criteria for the diagnosis of celiac disease are changing, but in adults, diagnosis still depends on the presence of duodenal villous atrophy while the patient is on a gluten-containing diet, along with findings from serology analysis. Although guidelines in the United States continue to mandate a biopsy at all ages, some children receive a diagnosis of celiac disease without a biopsy. If proven accurate and scalable, assays that detect gluten-HLA tetramer complexes might be used in diagnosis to be made in the context of a gluten-free diet without intestinal biopsy.

Non-responsive celiac disease may coincide with additional food intolerance/malabsorption, including histamine intolerance. Med Hypotheses 2020; 146:110404.

Abstract
BACKGROUND AND PILOT STUDY Celiac disease (CD) or gluten malabsorption is a well-defined autoimmune disorder characterized by mucosal gastrointestinal reaction to ingested gluten proteins. The necessary treatment for CD is a gluten-free diet. However, up to 30% of celiac patients experience persistent or recurring abdominal complaints despite following an exact gluten-free diet. This condition was named refractory, non-responsive celiac disease. Other food ingredients, such as carbohydrates and biogenic amines, also influence and impair digestion, and may cause these abdominal symptoms. In this retrospective pilot study, we have reported on 20 non-responsive, celiac disease patients, with persistent abdominal complaints, for longer than 6 months. These patients were evaluated for extra food intolerance/malabsorption, including fructose malabsorption, histamine-, lactose intolerance, and Helicobacter pylori (H.p.) infection. RESULTS AND CONCLUSIONS The results demonstrate that 18 of the 20 refractory, non-responsive celiac disease patients presented various, additional food intolerance/malabsorption and/or H.p. infection. Seven NRCD patients demonstrated lactose intolerance, 7 showed fructose malabsorption, 11 had additional histamine intolerance and 6 had signs of H.p. infection or combinations thereof. If present, then eradication of H.p. was performed. Histamine intolerance, was found in more than 50% of patients, and it seems to play an important role in non-responsive celiac disease. A registered dietician continued to help with, and to improve, the patients' gluten-free diet. Furthermore, additional food intolerance/malabsorption considerations were included in the individual, dietary recommendations.

Abstract
Helicobacter pylori is the leading cause of peptic ulcer disease. The infection has been implicated in more than 75% of duodenal ulcer cases and 17% of gastric ulcer cases. H. pylori has been classified as a human carcinogen, since it is the main cause of distal gastric adenocarcinoma and B cell mucosa-associated lymphoid tissue lymphoma. Evidence also links H. pylori with extragastric conditions including iron deficiency anemia, idiopathic thrombocytopenic purpura, and vitamin B12 deficiency. Studies indicate that H. pylori may be protective against other conditions of the gastrointestinal tract (e.g., reflux esophagitis and related pathologies) and elsewhere in the body (e.g., asthma). The infection is asymptomatic in the vast majority of cases; more serious outcomes occur in only 10-15% of infected individuals. Despite extensive research over the past 3 decades, there is no effective vaccine, and the circumstances leading to disease development remain unclear. In addition, there is now a growing prevalence of antimicrobial resistance in H. pylori. This review discusses these important issues.

[PMID: 33053671 PMCID: PMC7600664 DOI: 10.3390/jcm9103253] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2020] [Revised: 09/28/2020] [Accepted: 10/07/2020] [Indexed: 02/06/2023] Open
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
This review takes into account recent publications focusing on the relationship between Helicobacter pylori infection and non-malignant diseases of the upper gastro-intestinal tract. The authors have summarized current knowledge on associations between the H pylori infection and non-malignant upper GI conditions including gastroesophageal reflux disease (GERD), Barrett's esophagus, eosinophilic esophagitis (EOE), peptic ulcer disease (PUD), H pylori gastritis, celiac disease and functional dyspepsia. In the field of GERD, current data focusing on different locations of H pylori infection detect significant differences between antrum- and corpus predominant gastritis explainable by different changes in acid secretion in different gastric niches. High volume studies from Sweden and Brazil underline the safety of H pylori eradication concerning the risk of Barret's esophagus or adenocarcinoma. The relationship betweenH pylori infection and EOE remains uncertain, but current data supports the concept of expected positive and protective effects of H pylori exposure reducing the risk of EOE. Analyzing biomarkers might be helpful to identify subjects under risk for the development of precancerous lesions after H pylori infection, where microRNAs, IL-9 and IL-4, and also Tc17/9 and Th17/9 and microbiota profiles showed promising results to identify subgroups under risk.

Abstract
Celiac Disease (CD) is an immune-mediated enteropathy, generally of the proximal intestine, that occurs in genetically susceptible individuals triggered by the ingestion of gluten. The incidence and frequency of CD are increasing, and it is predicted that CD affects approximately 1% of the people worldwide. The common clinical manifestations of CD are divided in two sections, including classic and non-classic symptoms that can be created in childhood and adulthood. The relationship between pathogenic and non-pathogenic bacteria with CD is complex and multidirectional. In previous published studies, results demonstrated the triggering impact of bacteria, viruses, and parasites on initiation and development of Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS). Different studies revealed the inducing effect of pathogenic and non-pathogenic bacteria on CD. However, increasing evidence proposes that some of these microorganisms can also play several positive roles in CD process. Although information of the pathogenesis of the CD is quickly expanding, the possible role of bacteria needs further examination. In conclusion, with respect to the possible correlation between different bacteria in CD, the current review-based study aims to discuss the possible relationship between CD and pathogenic and non-pathogenic bacteria and to show various and significant aspects of mechanisms involved in the CD process.

Abstract
In westernized countries, adverse reactions to ingested foods are reported to affect up to 20% of the population. Functional, nonspecific, non-allergic gastrointestinal complaints are mainly due to the intolerance/malabsorption of carbohydrates (lactose and fructose), proteins (gluten), and biogenic amines (histamine). Food intolerance/malabsorption is defined by one or several of the above mentioned food components not being degraded and/or absorbed properly within the gastrointestinal tract. Food intolerance/malabsorption causes variable, functional, nonspecific, non-allergic gastrointestinal and extra-intestinal complaints, and a detailed diagnostic workup for all possible etiologic factors in individual patients is essential. Usually, evaluation for histamine intolerance is not included in differential diagnoses of patients with functional, nonspecific, non-allergic gastrointestinal complaints. A targeted dietary intervention for single or possibly combined intolerance/malabsorption is required. In this article, we review currently discussed differential diagnoses and available tests for intolerance/malabsorption. Accordingly, we aim to outline why including histamine and, histamine intolerance, should be considered in differential diagnoses of patients with functional, nonspecific, non-allergic gastrointestinal complaints.

Abstract
Asthma and allergy incidence continue to increase globally. We have made significant strides in treating disease, but it is becoming more apparent that we need to advance our knowledge into the origins of asthmatic disease. Much recent work has indicated that microbiome composition influences immune regulation and that multiple health care factors have driven a loss in microbiome diversity in modern human populations. Evidence is growing of microbiota-driven influences on immune development, asthma susceptibility, and asthma pathogenesis. The focus of this review is to highlight the strides the field has made in characterizing the constituents of the human gastrointestinal microbiota, such as Helicobacter pylori, other members of the neonatal intestinal microbiota, and microbial peptides and metabolites that influence host immunity and immune response to allergens. As we delve further into this field of research, the goal will be to find actionable and clinical interventions to identify at-risk populations earlier to prevent disease onset. Manipulation of the host microbial community during infancy might be an especially promising approach.

Abstract
Beyond the small intestine, coeliac disease (CeD) may affect other gastrointestinal tracts, including the stomach. However, various studies have reported conflicting results regarding the association between CeD and gastric manifestations. The aim of this study was to analyze the existing literature on gastric involvement in CeD. A literature search was conducted in bibliographic databases of Embase, PubMed, Scopus, and Web of Science. Studies reporting the association between CeD and gastric disorders were examined in detail and are fully described in the review. Both in children and adults, a strong correlation between lymphocytic gastritis and CeD was found at CeD diagnosis, and lymphocytic gastritis seemed to improve on a gluten-free diet. Most of the literature described a lower risk of gastritis related to Helicobacter pylori infection in CeD subjects compared to controls. However, due to the discordance among studies in terms of study design and population, a clear association could not be determined. Finally, the relationship between CeD and reflux or dyspepsia has yet to be defined, as well as the association between CeD and autoimmune gastritis. CeD appears to be a multiform entity associated with different gastric disorders with a different degree of relationship. Thus, gastric biopsies should be routinely taken during upper endoscopy in CeD patients.

Abstract
BACKGROUND An inverse association has been suggested between celiac disease (CD) and Helicobacter pylori (Hp) infection in children; however, there are inconsistent data. The purpose of this multi-center study is to evaluate the association between Hp and CD in childhood. METHODS Children who underwent endoscopy between July 2016 and November 2017 in four pediatric gastroenterology centers were included in the study. Patients with a history of previous Hp eradication, antibiotic or acid-suppressive drug therapy in the last 4 weeks, and any underlying chronic disease were excluded. The presence of Hp infection was confirmed by both histopathology and the rapid urease test. The ones who had the diagnosis of CD were compared with the children who underwent endoscopy during the same period and had another diagnosis. Duodenal histopathology of children with CD was categorized according to the modified Marsh classification. RESULTS Of 3056 endoscopies performed in the study period, 2484 cases were eligible for the study. A total of 482 CD patients (mean age: 9.71 ± 4.63 years, 58.5% girls) and 2060 controls (mean age: 9.92 ± 4.66 years, 54.6% girls) were included in the study. The rate of Hp infection was significantly lower in CD group (26.3% vs 50.1%, P < .01). The difference was prominent even in children younger than 6 years old (P < .01). There was no correlation between Hp infection and the modified Marsh scores in CD (P > .05). CONCLUSION In this cross-sectional study, where Hp infection is common even in the pediatric population, the frequency of Hp infection was significantly lower in children with CD compared with the controls. Systematic cohort studies are necessary to clarify causal association between Hp infection and the development of celiac disease.

Abstract
Celiac disease is a complex immune-mediated gluten-sensitive enteropathy with protean clinical manifestations. It is manifest in genetically predisposed individuals who ingest gluten in varying amounts. In broad terms, it is thought to affect 1% of the population in the USA. More specifically, the prevalence increases drastically from 1:133 in patients not-at-risk, to 1:56 in symptomatic patients, to 1:39 in patients with a second-degree relative with the diagnosis, and to 1:22 in patients with a first-degree relative with the diagnosis. It may be associated with several immune-mediated phenomena, autoimmune diseases, and complicated by vitamin and other trace element deficiencies, bone disease, and malignancy. Our understanding of celiac disease has evolved rapidly over the past two decades. This has led to several lines of enquiry on the condition and potential treatment options. More recently, several entities including gluten intolerance, non-celiac gluten sensitivity, and seronegative celiac disease have been described. These conditions are distinct from allergies or intolerance to wheat or wheat products. There are challenges in defining some of these entities since a large number of patients self-report these conditions. The absence of confirmatory diagnostic tests poses an added dilemma in distinguishing these entities. The differences in spectrum of symptoms and highlights of the variability between the pediatric and adult populations have been studied in some detail. The role of screening for celiac disease is examined in both the general population and "at risk" populations. Diagnostic strategies including the best available serologic testing, utility of HLA haplotypes DQ2 and DQ8 which are seen in over 90% of patients with celiac disease as compared with approximately 40% of the general population, and endoscopic evaluation are also reviewed. Comprehensive nutritional management after diagnosis is key to sustained health in patients with celiac disease. Simple algorithms for care based on a comprehensive multidisciplinary approach are proposed. Refractory and non-responsive celiac diseases in the setting of a gluten-free diet are examined as are novel non-dietary therapies. Finally, the association of other disease states including psychiatric illness, infertility, lymphoproliferative malignancy, and mortality is explored with special attention paid to autoimmune and atopic disease.

Abstract
The quality of wheat products has been a new challenge next to wheat production which was achieved substantially during green revolution. The end-use quality of wheat is an essential factor for its commercial demand. The quality of wheat is largely based on the wheat storage proteins which extensively influences the dough properties. High molecular weight glutenin subunits (HMWGS), low molecular weight glutenin subunits (LMWGS) and gliadins significantly influence the end-use quality. Genomics and proteomics study of these gluten proteins of bread and durum wheat have explored new avenues for precise identification of the alleles and their role in end-use quality improvement. Secalin protein of Secale cereale encoded by Sec-1 loci and is associated with 1RS.1BL translocation has been known for deterioration of end-use quality. Chromosomal manipulations using various approaches have led to the development of new recombinant lines of wheat without secalin. Advanced techniques associated with assessment of end-use quality have integrated the knowledge of useful or deteriorating HMWGS/LMWGS alleles and their potential role in end-use quality. This review gives a comprehensive insight of different aspects of the end-use quality perspective for bread making in wheat along with some information on the immunological interference of gluten in celiac disease.

Abstract
INTRODUCTION The aim of the study was to assess the prevalence of Helicobacter pylori (HP) in children with celiac disease (CD) and its relationship with clinical, histopathological, and laboratory parameters. MATERIAL AND METHODS Two hundred and fifty-six patients with serologically and histopathologically diagnosed CD at the Pediatric Gastroenterology Department, Turkey, from January 2012 to March 2017, were included in the study, as well as 1012 patients with dyspeptic complaints. Biopsies of the duodenum and antrum were taken; the existence of HP and the histological level of damage were studied. HP (+) and HP (-) cases were compared according to age, sex, noted complaints, and clinical and laboratory features. RESULTS Seventy (27.4%) CD patients and 270 (26.7%) patients with dyspeptic complaints were HP (+). The diagnostic age was higher in HP (+) cases, and diarrhea and abdominal distension were significantly higher. Although hemoglobin, ferritin, vitamin B12, and transferrin saturation were lower in HP (+) cases, the differences were not statistically significant. The serum folate level in the HP (+) group was significantly lower compared to the HP (-) group. CONCLUSIONS The prevalence of HP was not increased in cases of CD. The CD was diagnosed later in HP (+) cases, distension and diarrhea complaints were more frequent, and folate deficiency was significant.

Abstract
OBJECTIVE Correa's cascade is a 'Model for Gastric Cancer Development' described by Peleyo Correa. The reversibility of Correa's cascade remains debatable. The literature contains insufficient data on the specific stage of the cascade during which Helicobacter pylori is detected, treated, and the effect on prognosis. Herein, we aim to determine the prevalence of various precancerous and cancerous gastric lesions in patients presenting with dyspepsia, the prevalence of gastritis and H. pylori infection, the prevalence of duodenal pathology in patients presenting with dyspepsia, identify the stage of H. pylori detection in relation to Correa's cascade, and investigate a possible relationship between H. pylori and celiac disease. DESIGN Retrospective cross-sectional study conducted on a middle eastern population at a Lebanese tertiary hospital centre. 1428 patients presenting with dyspepsia underwent gastroscopy with gastric and duodenal biopsies. Variables include age, sex, presence/absence of H. pylori infection, and histopathological analysis of gastric and duodenal biopsies. RESULTS Being above 40 years of age was associated with increased likelihood of exhibiting abnormal gastric biopsy result. Gastritis and metaplasia were detected more frequently than glandular atrophy (p<0.001) with gastritis being present the most (p<0.001). The presence of H. pylori and the gastric biopsy results were not associated with any of the duodenal biopsy results. CONCLUSION The burden of H. pylori infection in patients with dyspepsia was high. H. pylori was detected at various precancerous lesions with varying significance. The prevalence of duodenal adenocarcinoma in dyspeptic patients is unexpectedly high. No association between gastric and duodenal pathologies was found.

Abstract
Celiac disease is a common, chronic inflammatory disorder of the small intestine triggered by exposure to gluten in individuals with certain genetic types. This disorder affects people of any age or gender. Although often thought to be European in origin, it is now global in extent. Presentations are variable, from asymptomatic patients to severe malnutrition. Initial detection usually relies on celiac-specific serology, and confirmation often requires intestinal biopsy. There have been substantial increases in prevalence and incidence over the last 2 decades for reasons that are almost certainly environmental but for which there is no clarity as to cause.

Abstract
BACKGROUND/AIMS The relationship between Helicobacter pylori and celiac disease (CD) remains controversial. The aim of this study was to assess the prevalence and risk factors for H. pylori infection among children diagnosed with CD. MATERIALS AND METHODS This study included 70 patients diagnosed with CD at a tertiary referral center in Romania. Age, gender, and indicators of environmental conditions were evaluated via interviews with the children's caretakers. A multivariable logistic regression analysis was performed to identify the independent predictors for H. pylori infection. RESULTS Of the 70 patients, 37 (52.9%) were females, and the mean age was 4.04±3.26 years. H. pylori infection was diagnosed in 23 (32.8%) patients, of whom 12 (52.1%) were females, and the mean age was 6.2±4.5 years. Of the total number of children with CD and H. pylori infection, 18 (78.2%) had milder forms of enteropathy (Marsh I-II), whereas the remaining 5 (21.7%) had villous atrophy compared to the other 47 (67.2%) patients who were negative for H. pylori-infection and showed more severe intestinal damage. The development of H. pylori infection was independently related to children with one parent only [odd ratio (OR), 9.04; 95% confidence interval (CI), 1.29-62.89; p<0.001], living in houses without sanitary facilities (OR, 3.88; 95% CI, 1.27-14.22; p=0.016), belonging to low-income families (OR, 8.52; 95% CI, 2.52-71.39; p=0.002), and of parents with a prior history of gastritis (OR, 2.68; 95% CI, 1.49-14.50; p=0.004). CONCLUSION Children with CD and H. pylori infection had milder forms of enteropathy compared to children who are negative for H. pylori, suggesting that H. pylori infection may confer some protection against the development of severe degrees of villous atrophy.

Abstract
Recent studies on celiac disease (CeD) have reported alterations in the gut microbiome. Whether this alteration in the microbial community is the cause or effect of the disease is not well understood, especially in adult onset of disease. The first-degree relatives (FDRs) of CeD patients may provide an opportunity to study gut microbiome in pre-disease state as FDRs are genetically susceptible to CeD. By using 16S rRNA gene sequencing, we observed that ecosystem level diversity measures were not significantly different between the disease condition (CeD), pre-disease (FDR) and control subjects. However, differences were observed at the level of amplicon sequence variant (ASV), suggesting alterations in specific ASVs between pre-disease and diseased condition. Duodenal biopsies showed higher differences in ASVs compared to fecal samples indicating larger disruption of the microbiota at the disease site. The duodenal microbiota of FDR was characterized by significant abundance of ASVs belonging to Parvimonas, Granulicatella, Gemella, Bifidobacterium, Anaerostipes, and Actinomyces genera. The duodenal microbiota of CeD was characterized by higher abundance of ASVs from genera Megasphaera and Helicobacter compared to the FDR microbiota. The CeD and FDR fecal microbiota had reduced abundance of ASVs classified as Akkermansia and Dorea when compared to control group microbiota. In addition, predicted functional metagenome showed reduced ability of gluten degradation by CeD fecal microbiota in comparison to FDRs and controls. The findings of the present study demonstrate differences in ASVs and predicts reduced ability of CeD fecal microbiota to degrade gluten compared to the FDR fecal microbiota. Further research is required to investigate the strain level and active functional profiles of FDR and CeD microbiota to better understand the role of gut microbiome in pathophysiology of CeD.

Abstract
BACKGROUND & AIMS Lymphocytic disorders of the upper and lower gastrointestinal tract seem to cluster in patients. We aimed to assess the frequency of comorbid occurrence of lymphocytic disorders in patients with microscopic colitis (MC). METHODS We collected data from the Miraca Life Sciences Database, a large national electronic repository of histopathologic records of patients throughout the United States. In a population of 228,506 patients who underwent bidirectional endoscopy from January 2008 through July 2016, we studied the comorbid occurrence of celiac disease, duodenal intraepithelial lymphocytosis, lymphocytic gastritis, and lymphocytic esophagitis among 3456 patients with MC. Associations were described in terms of their odds ratios (OR) and 95% CIs. RESULTS Any type of lymphocytic disorder occurred in 13.7% of patients with MC and 5.9% of patients without MC. The ORs of lymphocytic disorders in patients with MC were: 2.56 (95% CI, 2.32-2.82) for any type of lymphocytic disorder, 3.07 (95% CI, 1.25-7.52) for lymphocytic esophagitis, 15.05 (95% CI, 12.31-18.41) for lymphocytic gastritis, 1.73 (95% CI, 1.53-21.96) for duodenal intraepithelial lymphocytosis, and 6.06 (95% CI, 5.06-7.25) for celiac disease. Comorbidities were more common in patients with lymphocytic than collagenous colitis, with an OR of 1.74 (95% CI, 1.42-2.13). Patients with MC with comorbidities were significantly younger and had a lower proportion of men than patients with MC patients without comorbidities. Diarrhea was the predominant symptoms in all patients MC, irrespective of comorbidities. CONCLUSION In a retrospective study, we identified lymphocytic disorders of the upper gastrointestinal tract that are significantly more common in patients with than without MC. These associations suggest the existence of an underlying etiology that is common to all lymphocytic disorders and that affects the upper and lower gastrointestinal tract.

Abstract
Helicobacter pylori (H. pylori) is present in roughly 50% of the human population worldwide and infection levels reach over 70% in developing countries. The infection has classically been associated with different gastro-intestinal diseases, but also with extra gastric diseases. Despite such associations, the bacterium frequently persists in the human host without inducing disease, and it has been suggested that H. pylori may also play a beneficial role in health. To understand how H. pylori can produce such diverse effects in the human host, several studies have focused on understanding the local and systemic effects triggered by this bacterium. One of the main mechanisms by which H. pylori is thought to damage the host is by inducing local and systemic inflammation. However, more recently, studies are beginning to focus on the effects of H. pylori and its metabolism on the gastric and intestinal microbiome. The objective of this review is to discuss how H. pylori has co-evolved with humans, how H. pylori presence is associated with positive and negative effects in human health and how inflammation and/or changes in the microbiome are associated with the observed outcomes.

Abstract
BACKGROUND Celiac disease (CD) occurs in subjects positive for HLA-DQ2 and/or DQ8 gene loci at any age following ingestion of gluten-containing food. An increased permeability of the mucosa allows interactions between gliadin macromolecules and genetic factors. It has been observed that Helicobacter pylori has the ability to modulate the integrity of the duodenal epithelium. We aimed to determine whether H. pylori infection may enhance the occurrence of CD in genetically susceptible subjects. MATERIALS AND METHODS This was a prospective observational study. Patients undergoing upper endoscopy for any reason and positive for HLA-DQ2 and/or DQ8 haplotypes with or without CD were included. H. pylori infection was defined as a positive gastric histopathology and/or 13C-urea breath test. Prevalence of infection was compared between enrolled subjects with and without CD. Multiple logistic regression analysis, adjusting odds ratios for patient age, gender, smoking habit, residency, body mass index, and assumption of nonsteroidal anti-inflammatory drugs (NSAIDs) and proton-pump inhibitors (PPIs) were performed. RESULTS A total of 397 genetically susceptible individuals (mean age: 37.7 ± 15.3 years; 86% women) were enrolled between October 2014 and October 2017. There were 265 (68%) patients with a diagnosis of CD. Overall, the prevalence of H. pylori infection was 33% and was similar in patients with and without CD (32% vs 36%). Adjustment for all covariates did not reveal any significant association, although adjusted odds ratio (OR) for CD was higher in female (OR = 1.302), in patients H. pylori positive (OR = 1.277), followed by use of NSAIDs (OR = 1.126), respectively. The use of PPIs appeared to be mildly protective against CD (OR = 0.644). CONCLUSION Our study did not reveal any significant relationship between H. pylori and CD risk, even taking into account other confounders. More importantly, our findings do not support a "protective" role of H. pylori infection against CD, as previously reported. Therefore, there are no reasons to avoid eradication of H. pylori also in subject genetically susceptible for CD.

Abstract
Coeliac disease occurs in about 1% of people in most populations. Diagnosis rates are increasing, and this seems to be due to a true rise in incidence rather than increased awareness and detection. Coeliac disease develops in genetically susceptible individuals who, in response to unknown environmental factors, develop an immune response that is subsequently triggered by the ingestion of gluten. The disease has many clinical manifestations, ranging from severe malabsorption to minimally symptomatic or non-symptomatic presentations. Diagnosis requires the presence of duodenal villous atrophy, and most patients have circulating antibodies against tissue transglutaminase; in children, European guidelines allow a diagnosis without a duodenal biopsy provided that strict symptomatic and serological criteria are met. Although a gluten-free diet is an effective treatment in most individuals, a substantial minority develop persistent or recurrent symptoms. Difficulties adhering to a gluten-free diet have led to the development of non-dietary therapies, several of which are undergoing trials in human beings.

Abstract
Our understanding of celiac disease and how it develops has evolved significantly over the last half century. Although traditionally viewed as a pediatric illness characterized by malabsorption, it is now better seen as an immune illness with systemic manifestations affecting all ages. Population studies reveal this global disease is common and, in many countries, increasing in prevalence. These studies underscore the importance of specific HLA susceptibility genes and gluten consumption in disease development and suggest that other genetic and environmental factors could also play a role. The emerging data on viral and bacterial microbe-host interactions and their alterations in celiac disease provides a plausible mechanism linking environmental risk and disease development. Although the inflammatory lesion of celiac disease is complex, the strong HLA association highlights a central role for pathogenic T cells responding to select gluten peptides that have now been defined for the most common genetic form of celiac disease. What remains less understood is how loss of tolerance to gluten occurs. New insights into celiac disease are now providing opportunities to intervene in its development, course, diagnosis, and treatment.

Abstract
The gastrointestinal (GI) tract harbors a diverse and host-specific gut microbial community. Whereas host-microbe interactions are based on homeostasis and mutualism, the microbiome also contributes to disease development. In this review, we summarize recent findings connecting the GI microbiome with GI disease. Starting with a description of biochemical factors shaping microbial compositions in each gut segment along the longitudinal axis, improved histological techniques enabling high resolution visualization of the spatial microbiome structure are highlighted. Subsequently, inflammatory and neoplastic diseases of the esophagus, stomach, and small and large intestines are discussed and the respective changes in microbiome compositions summarized. Finally, approaches aiming to restore disturbed microbiome compositions thereby promoting health are discussed.

Abstract
OBJECTIVES Patients with celiac disease are at increased risk for infections such as tuberculosis, influenza, and pneumococcal pneumonia. However, little is known about the incidence of Clostridium difficile infection (CDI) in patients with celiac disease. METHODS We identified patients with celiac disease based on intestinal biopsies submitted to all pathology departments in Sweden over a 39-year period (from July 1969 through February 2008). We compared risk of CDI (based on stratified Cox proportional hazards models) among patients with celiac disease vs. without celiac disease (controls) matched by age, sex, and calendar period. RESULTS We identified 28,339 patients with celiac disease and 141,588 controls; neither group had a history of CDI. The incidence of CDI was 56/100,000 person-years among patients with celiac disease and 26/100,000 person-years among controls, yielding an overall hazard ratio (HR) of 2.01 (95% confidence interval (CI), 1.64-2.47; P<0.0001). The risk of CDI was highest in the first 12 months after diagnosis of celiac disease (HR, 5.20; 95% CI, 2.81-9.62; P<0.0001), but remained high, compared to that of controls, 1-5 years after diagnosis (HR, 1.85; 95% CI, 1.22-2.81; P=0.004). Among 493 patients with CDI, antibiotic data were available for 251; there were no significant differences in prior exposures to antibiotics between patients with celiac disease and controls. CONCLUSIONS In a large population-based cohort study, patients with celiac disease had significantly higher incidence of CDI than controls. This finding is consistent with prior findings of higher rates of other infections in patients with celiac disease, and suggests the possibility of altered gut immunity and/or microbial composition in patients with celiac disease.

Abstract
BACKGROUND Helicobacter pylori quantity and HP-NAP gene expression were evaluated in the faeces of healthy and asthmatic children. METHODS H. pylori DNAs and RNAs were isolated from the stool samples of 92 asthmatic children (AC; 3-8 years) and 88 healthy controls (HC). Quantitative PCR was used to determine the quantity of H. pylori and HP-NAP expression relative to the 16S rRNA (reference gene). Gene expression was analysed using the delta delta-Ct method. RESULTS H. pylori DNA was detected in the stool samples of 18 (20.4%) of the 88 HC (p<0.0001, OR=0.79) and none of AC. No meaningful statistical differences were found between individuals with positive and negative family histories for asthma in AC and HC (p>0.05). H. pylori quantity was higher in seven of 18 H. pylori-positive samples, but HP-NAP expression levels were low in four of these seven samples. Based on a multivariate logistic regression analysis of these three variables together, only males displayed a significant difference based on gender differences (p<0.02) and it was determined that, based on the OR value of 0.46 and the 95% CI range of 0.241-0.888, male gender was an independent protective factor in asthma. CONCLUSIONS HP-NAP levels vary to the relative concentrations of bacteria in the stationary or late logarithmic phases. Different napA expression levels may be caused by different endogenous napA gene expression or different environmental conditions.

Abstract
A promising treatment for T-cell-mediated autoimmune diseases is the induction of immune tolerance by modulating the immune response against self-antigens, an objective that may be achieved by vaccination. There are two main types of vaccines currently under development. The tolerogenic vaccines, composed of proteins formed by a cytokine fused to a self-antigen, which usually induce tolerance by eliminating the T-cells that are immune reactive against the self-antigen. The immunogenic vaccines, comprised of a self-antigen plus a sole Th2 adjuvant either free or conjugated, that alleviate autoimmunity by switching the immune response against the self-antigen, from a damaging pro-inflammatory Th1/Th17 to an anti-inflammatory Th2 immunity. Another type of vaccines is the DNA vaccines, where cells transiently express the self-antigen encoded by DNA, which induces a Th2 immunity. Actually, DNA vaccines can benefit from the presence of an adjuvant that elicits a systemic sole Th2 immunity to enhance the initially weak immune response characteristic of these vaccines. While in the tolerogenic vaccines, cytokines are the endogenous immunomodulators, in the immunogenic vaccines, the adjuvants are exogenous agents that elicit Th2 immunity with a production of anti-inflammatory cytokines and antibodies against the self-antigen. Because the commonly used Th2 adjuvant alum, fails to induce an effective immunity in the elderly population, it is unlikely that it would be widely used. Another Th2 adjuvant, the oil/water emulsions mixed with the antigen, while effective in vaccines against infectious agents, due to potential aldehydes in their formulation may be not suitable for autoimmune vaccines. A unique compound is glatiramer, which seems to be both a random polypeptide antigen and an immune modulator that biases the response to Th2 immunity. Its mechanism of action seems to implicate binding to MHC-II, which alters the outcome of T-cell signaling, leading to anergy. Glatiramer, while effective in the treatment of multiple sclerosis has not shown efficacy in other autoimmune diseases. An important new group of promising sole Th2 adjuvants are the fucosylated glycans, which by binding to DC-SIGN bias dendritic cells to Th2 immunity while inhibiting Th1/Th7 immunities. These glycans are similar to those produced by parasitic helminths to prevent inflammatory responses by mammalian hosts. A novel group of sole Th2 adjuvants are some plant-derived fucosylated triterpene glycosides, which share the immune modulatory properties from the fucosylated glycans. These glycosides have also an aldehyde group that delivers an alternative co-stimulatory signal to T-cells, averting the anergy associated with aging due to the loss of the CD28 receptor on T-cells. Hence, the development of vaccines to treat and/or prevent autoimmune conditions and some proteopathies, will significantly benefit from the availability of new sole Th2 adjuvants that while inducing an anti-inflammatory immunity, they do not abrogate pro-inflammatory Th1/Th17 immunities.

Abstract
HIGHLIGHTSWhat is already known about this subject? Celiac disease (CD) has a high clinical and histological diversity and the mechanisms underlying this phenomenon remain elusive. H. pylori is a bacterium that chronically infect gastric and duodenal mucosa activating both a Th1/Th17 and T-reg pathways. The role of H. pylori (and the effect of their virulence factors) in CD have not yet completely elucidated. What are the new findings? cagA+ H. pylori strains are associated to milder histological damage in infected CD patients. In active-CD patients the presence of cagA+ H. pylori is associated to an increase in T-reg markers, contrasting with a downregulation in cagA+ infected potential-CD individuals. How might it impact on clinical practice in the foreseeable future? The identification of microbiological factors that could modulate inflammation and clinical expression of CD may be used in the future as preventive strategies or as supplementary treatment in patients that cannot achieve complete remission, contributing to the better care of these patients.
Background: Mechanisms underlying the high clinical and histological diversity of celiac disease (CD) remain elusive. Helicobacter pylori (Hp) chronically infects gastric and duodenal mucosa and has been associated with protection against some immune-mediated conditions, but its role (specifically of cagA+ strains) in CD is unclear. Objective: To assess the relationship between gastric Hp infection (cagA+ strains) and duodenal histological damage in patients with CD. Design: Case-control study including patients with active-CD, potential-CD and non-celiac individuals. Clinical presentation, HLA genotype, Hp/cagA gene detection in gastric mucosa, duodenal histology, Foxp3 positive cells and TGF-β expression in duodenal lamina propria were analyzed. Results: We recruited 116 patients, 29 active-CD, 37 potential-CD, and 50 non-CD controls. Hp detection was similar in the three groups (~30–40%), but cagA+ strains were more common in infected potential-CD than in active-CD (10/11 vs. 4/10; p = 0.020) and non-CD (10/20; p = 0.025). Among active-CD patients, Foxp3 positivity was significantly higher in subjects with cagA+ Hp+ compared to cagA- Hp+ (p < 0.01) and Hp- (p < 0.01). In cagA+ Hp+ individuals, Foxp3 positivity was also higher comparing active- to potential-CD (p < 0.01). TGF-β expression in duodenum was similar in active-CD with cagA+ Hp+ compared to Hp- and was significantly downregulated in cagA+ potential-CD subjects compared to other groups. Conclusion: Hp infection rates were similar among individuals with/without CD, but infection with cagA+ strains was associated with milder histological damage in celiac patients infected by Hp, and in active-CD cases with higher expression of T-reg markers. Results suggest that infection by cagA+ Hp may be protective for CD progression, or conversely, that these strains are prone to colonize intestinal mucosa with less severe damage.

Abstract
Purpose The prevalence of Helicobacter pylori gastritis has been declining, whereas H. pylori-negative gastritis has become more common. We evaluated chronic gastritis in children with regard to H. pylori status and celiac disease (CD). Patients and methods Demographic, clinical, endoscopic, and histologic features of children who underwent elective esophagogastroduodenoscopy were reviewed retrospectively. Gastric biopsies from the antrum and corpus of the stomach were graded using the Updated Sydney System. H. pylori presence was defined by hematoxylin and eosin, Giemsa, or immunohistochemical staining and urease testing. Results A total of 184 children (61.9% female) met the study criteria with a mean age of 10 years. A total of 122 (66.3%) patients had chronic gastritis; 74 (60.7%) were H. pylori-negative. Children with H. pylori-negative gastritis were younger (p=0.003), were less likely to present with abdominal pain (p=0.02), and were mostly of non-Arabic origin (p=0.011). Nodular gastritis was found to be less prevalent in H. pylori-negative gastritis (6.8%) compared with H. pylori-positive gastritis (35.4%, p<0.001). The grade of mononuclear infiltrates and neutrophil density was more severe in the H. pylori-positive group (p<0.001). Pan-gastritis and lymphoid follicles were associated most commonly with H. pylori. Although less typical, lymphoid follicles were demonstrated in 51.3% of H. pylori-negative patients. The presence or absence of CD was not associated with histologic findings in H. pylori-negative gastritis. Conclusion Our findings suggest that lymphoid follicles are a feature of H. pylori-negative gastritis in children independent of their CD status.

The impact of acid suppression medications and non-steroidal anti-inflammatory drugs on clinical and histologic features in celiac disease. Dig Liver Dis 2017; 49:883-886. [PMID: 28462884 PMCID: PMC5511753 DOI: 10.1016/j.dld.2017.03.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2016] [Revised: 03/14/2017] [Accepted: 03/15/2017] [Indexed: 12/11/2022]
Abstract
INTRODUCTION The prevalence of celiac disease (CD) in the US has increased in past decades, as has use of proton pump inhibitors (PPIs), histamine-2-receptor antagonists (H2RAs), aspirin (ASA) and nonsteroidal anti-inflammatory drugs (NSAIDs). We aimed to measure the association between medication use and distribution of villous flattening (VF) among newly diagnosed CD patients. METHODS We performed a cross-sectional study of adult patients with newly-diagnosed CD at two institutions. We collected data on regular use of these medications, clinical presentation, CD serologic status, and distribution of VF. We compared current ASA/NSAID users to non-users, and current PPI/H2RA users to non-users, with regard to these clinical characteristics. RESULTS Of 148 patients with newly-diagnosed CD, current users of ASA/NSAIDs were older than non-users (47 vs 39 years, p=0.003) and users of PPI/H2RAs were older than non-users (48 vs 39 years, p=0.004). PPI/H2RA users comprised 12% of seropositive patients, compared to 55% of seronegative patients (p<0.01). Patient gender and distribution of villous flattening in the bulb and distal duodenum did not differ by PPI/H2RA or ASA/NSAID use. CONCLUSIONS PPI/H2RA use was associated with seronegative CD. Given the effect of these medications on gastric milieu, the impact of these drugs on presentation and course of CD deserves further investigation.
