Risk factors associated with Helicobacter pylori infection in the urban population of China: A nationwide, multi-center, cross-sectional study. Int J Infect Dis 2025; 154:107890. [PMID: 40096882 DOI: 10.1016/j.ijid.2025.107890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2024] [Revised: 03/11/2025] [Accepted: 03/12/2025] [Indexed: 03/19/2025] Open
Abstract
OBJECTIVES To assess the risk factors associated with Helicobacter pylori infection in the urban Chinese population. METHODS The study was conducted from March to November 2023, including 12,902 urban participants aged 18-60 years across 52 cities distributed over 26 provinces in China. Risk factors included socioeconomic status, lifestyles, and public understanding. Univariate and multivariate logistic regression analysis was used to calculate corrected odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS According to multivariate logistic regression, risk factors associated with significantly higher H. pylori infection rates included residency in developing (OR 1.27, 95% CI 1.13-1.43) and undeveloped cities (OR 1.15, 95% CI 1.02-1.29), obesity (OR 1.37, 95% CI 1.05-1.78), alcohol consumption (OR 1.16, 95% CI 1.05-1.29), tea consumption (OR 1.11, 95% CI 1.01-1.21), and soft drink consumption (OR 1.24, 95% CI 1.09-1.40). Conversely, individuals with moderate awareness (OR 0.79, 95% CI 0.71-0.88) and high awareness (OR 0.57, 95% CI 0.48-0.69) of H. pylori had lower infection rates. CONCLUSION Our findings highlight the importance of promoting a healthy lifestyle and improving the understanding of H. pylori in reducing the infection rate of the bacterial pathogen in the urban Chinese population.

Ann Med Surg (Lond) 2025; 87:583-597. [PMID: 40110261 PMCID: PMC11918594 DOI: 10.1097/ms9.0000000000002977] [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: 08/27/2024] [Accepted: 01/12/2025] [Indexed: 03/22/2025] Open
Abstract
Chronic gastritis (CG), particularly when associated with Helicobacter pylori (H. pylori) infection, is a significant precursor to gastric cancer (GC), a leading cause of cancer-related deaths worldwide. The persistent inflammation in CG, driven by factors such as H. pylori, induces oxidative stress and DNA damage in gastric epithelial cells, which can lead to malignant transformation. Atrophic gastritis, a form of CG, can be categorized into autoimmune and H. pylori-associated types, both of which increase the risk of GC development, particularly when compounded by external factors like smoking and dietary habits. This manuscript explores the pathophysiological mechanisms underlying CG and its progression to GC, highlighting the critical role of metabolomics in advancing our understanding of these processes. Metabolomics, the comprehensive study of metabolites, offers a novel approach to identifying biomarkers that could facilitate early detection and improve the accuracy of GC diagnosis and prognosis. The analysis of metabolic alterations, particularly in glucose, lipid, and amino acid metabolism, reveals distinct biochemical pathways associated with the progression from benign gastritis to malignancy. Integrating metabolomic profiling with traditional diagnostic methods can revolutionize GC management, enabling more personalized treatment strategies and improving clinical outcomes. However, significant challenges remain, including the need to validate biomarkers across diverse populations and standardize metabolomic techniques. Future research should address these challenges to fully realize the potential of metabolomics in early GC detection and treatment, ultimately aiming to reduce the global burden of this deadly disease.

[PMID: 39713168 PMCID: PMC11612857 DOI: 10.3748/wjg.v30.i47.5018] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2024] [Revised: 09/12/2024] [Accepted: 09/23/2024] [Indexed: 11/26/2024] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection exhibits a familial clustering phenomenon. AIM To investigate the prevalence of H. pylori infection, identify associated factors, and analyze patterns of transmission within families residing in the community. METHODS From July 2021 to September 2021, a total of 191 families (519 people) in two randomly chosen community health service centers in the Chengguan District of Lanzhou in Gansu Province, were recruited to fill out questionnaires and tested for H. pylori infection. Individuals were followed up again from April 2023 and June 2023 to test for H. pylori infection. The relationship between variables and H. pylori infection was analyzed using logistic regression and generalized linear mixed models. RESULTS In 2021, the individual-based H. pylori infection rate was found to be 47.0% (244/519), which decreased to 38.1% (177/464) in 2023. Additionally, the rate of individual-based H. pylori new infection was 22.8% (55/241). The family-based H. pylori infection rate in 2021 was 76.9% (147/191), which decreased to 67.1% (116/173) in 2023, and the rate of family-based H. pylori new infection was 38.6% (17/44). Individual H. pylori infection was positively correlated with age, body mass index (BMI), eating food that was excessively hot, frequent acid reflux, bloating, and halitosis symptoms, and negatively correlated with family size and nut consumption. New individual H. pylori infection was positively correlated with BMI, other types of family structures, drinking purified water, and frequent heartburn symptoms, while negatively correlated with the use of refrigerators and following a regular eating schedule. A larger living area was an independent protective factor for H. pylori infection in households. Frequently consuming excessively hot food and symptoms of halitosis were independent risk factors for H. pylori infection in individuals; frequent consumption of nuts was an independent protective factor for H. pylori infection. Other types of family structure, drinking purified water, and frequent heartburn symptoms were independent risk factors for new individual H. pylori infection; the use of a refrigerator was an independent protective factor for new H. pylori infections. CONCLUSION The household H. pylori infection rate in Lanzhou is relatively high and linked to socio-demographic factors and lifestyles. Eradication efforts and control of related risk factors are recommended in the general population.

Helicobacter pylori infection and staple-line leak in patients with class III obesity undergoing laparoscopic sleeve gastrectomy: a retrospective study. BMJ Open Gastroenterol 2024; 11:e001622. [PMID: 39797659 PMCID: PMC11664374 DOI: 10.1136/bmjgast-2024-001622] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2024] [Accepted: 12/02/2024] [Indexed: 01/13/2025] Open
Abstract
OBJECTIVE Globally, over 50% of the population is affected by Helicobacter pylori, yet research on its prevalence and impact in patients with obesity undergoing laparoscopic sleeve gastrectomy (LSG) is inconclusive. This study aimed to assess the prevalence of H. pylori infection in individuals with obesity undergoing LSG, evaluate the percentage of postoperative staple-line leaks, and explore the potential link between H. pylori infection and staple-line leaks. METHODS This retrospective analysis assessed adult patients with class III obesity who underwent LSG between 2015 and 2020 at a tertiary care hospital in Riyadh, Saudi Arabia. Patient characteristics with and without postoperative staple-line leaks were compared, exploring the link between H. pylori infection and these leaks. RESULTS Of the 2099 patients (mean age, 34.7±12.2 years; female, 53.5%) included, 35% had H. pylori infection and 2% experienced post-LSG staple-line leaks. Patients with H. pylori were older (36.1±11.8 vs 34.0±12.3 years, p<0.0001). Patients with leaks were older, mostly male, and had higher body mass index (p<0.05). However, only 29% of those with leaks were H. pylori-positive. A non-significant association was found between H. pylori infection and staple-line leaks (adjusted OR 0.73, 95% CI 0.33 to 1.60, accounting for age, body mass index, and sex). CONCLUSIONS Although over one-third of patients with class III obesity undergoing LSG had H. pylori infection, a non-significant association was observed with post-LSG staple-line leaks, suggesting routine preoperative H. pylori screening may not be necessary.

Int J Obes (Lond) 2024; 48:1664-1672. [PMID: 39179750 PMCID: PMC11502492 DOI: 10.1038/s41366-024-01611-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 07/29/2024] [Accepted: 08/08/2024] [Indexed: 08/26/2024]
Abstract
BACKGROUND Obesity and diabetes mellitus (DM) have become public health concerns worldwide. Both conditions have severe consequences and are associated with significant medical costs and productivity loss. Additionally, Helicobacter pylori infection may be a risk factor for the development of these conditions. However, whether eradicating H. pylori infection directly causes weight loss or improves insulin sensitivity is unknown. METHODS In this study, we confirmed the effect of sleeve gastrectomy according to the state of the gastric microbiota in 40 patients with obesity, DM, and H. pylori infection. Patients with obesity were divided into four groups: non-DM without H. pylori infection (ND), non-DM with H. pylori infection (ND-HP), DM, and DM with H. pylori infection (DM-HP) using 16S V3-V4 sequencing. RESULTS In the DM group, ALT, hemoglobin, HbA1c, blood glucose, and HSI significantly decreased, whereas high-density lipoprotein significantly increased. However, in the H. pylori-positive group, no significant difference was observed. The diversity of gastric microbiota decreased in the order of the ND > DM > ND-HP > DM-HP groups. We also conducted a correlation analysis between the preoperative microbes and clinical data. In the ND-HP group, most of the top 20 gastric microbiota were negatively correlated with glucose metabolism. However, H. pylori infection was positively correlated with pre-insulin levels. CONCLUSION Therefore, these findings indicate that patients with obesity and diabetes clearly benefit from surgery, but H. pylori infection may also affect clinical improvement.

Abstract
BACKGROUND Recent studies on the association between Helicobacter pylori (H. pylori) infection and obesity have reported conflicting results. Therefore, the purpose of our study was to investigate the association of obesity, abdominal obesity, and metabolic obesity phenotypes with H. pylori infection. METHODS A cross-sectional study of 1568 participants aged 20 to 85 was conducted using the National Health and Nutrition Examination Survey (NHANES) cycle 1999-2000. Logistic regression models were employed to evaluate the association of general obesity as defined by body mass index (BMI), abdominal obesity as defined by waist circumference (WC) and waist-height ratio (WHtR), and metabolic obesity phenotypes with H. pylori seropositivity. Subgroup analyses stratified by age were conducted to explore age-specific differences in this association. RESULTS After grouping individuals according to their WHtR, the prevalence rate of WHtR ≥ 0.5 in H. pylori-seropositive participants was significantly higher than that in H. pylori-seronegative participants (79.75 vs. 68.39, P < 0.001). The prevalence of H. pylori seropositivity in non-abdominal obesity and abdominal obesity defined by WHtR was 24.97% and 31.80%, respectively (P < 0.001). In the subgroup analysis, the adjusted association between abdominal obesity, as defined by the WHtR, and H. pylori seropositivity was significant in subjects aged < 50 years (OR = 2.23; 95% CI, 1.24-4.01; P = 0.01) but not in subjects aged ≥ 50 years (OR = 0.84; 95% CI, 0.35-1.99; P = 0.66). Subjects older than 50 years old had an OR (95% CI) for metabolically healthy obesity of 0.04 (0.01-0.35) compared with the control group. H. pylori seropositivity was consistently not associated with obesity as defined by BMI. CONCLUSIONS Abdominal obesity, as defined by the WHtR, was associated with H. pylori infection in subjects aged ≤ 50 years.

Abstract
The impact of Helicobacter pylori (HP) on postoperative outcomes after sleeve gastrectomy (SG) is still controversial. A systematic review and meta-analysis were performed to compare the incidence of early complications after SG between HP-positive and HP-negative patients. Eight retrospective comparative studies were included, comprising 4,877 individuals. The prevalence of HP infection in gastric resected specimens ranged from 7.77 to 43.20%. There were no statistically significant differences between groups for overall complications (OR 1.46; 95%CI 0.95-2.23; p=0.08), bleeding (OR 1.35; 95%CI 0.70-2.60; p=0.38), and leak (OR 1.74; 95%CI 0.80-3.81; p=0.17) rates. The need for routine screening and treatment of HP infection before SG remains ambiguous.

Dual burden of infectious and chronic disease in low-resource U.S. communities: examining relationships between infection, adiposity, and inflammation. Ann Hum Biol 2024; 51:2368851.

Abstract
BACKGROUND Rising global obesity rates are linked with inflammation and associated morbidities. These negative outcomes are generally more common in low-resource communities within high-income countries; however, it is unclear how frequent infectious disease exposures in these settings may influence the relationship between adiposity and inflammation. AIM We test associations between adiposity measures and distinct forms of inflammation among adults (n = 80) living in low-resource U.S. communities experiencing high levels of obesity and pathogen exposure. SUBJECTS AND METHODS Adiposity measures included BMI and percent body fat. Inflammation measures included systemic inflammation (C-reactive protein [CRP]) and localised intestinal inflammation (faecal calprotectin [FC]). The relationship between a condition characterised by elevated inflammation (Helicobacter pylori infection) and adiposity was also considered. RESULTS Adiposity was not significantly related to FC concentration. However, both adiposity measures were positively related with odds of CRP elevation and H. pylori infection was associated with significantly lower adiposity measures (all p < 0.05). CONCLUSION For this disadvantaged U.S. sample, the association between adiposity and inflammation varies by the systemic/localised nature of inflammation and the likely underlying cause of inflammation. Defining these associations will improve understanding of how rising obesity rates shape long-term health inequities, with implications for more effective intervention design.

Abstract
PURPOSE Helicobacter pylori (HP) is the most common human infection that has affected up to 50% of the population worldwide. The relationship between HP eradication and weight loss is under debate. The present study aimed to compare weight loss outcomes after Roux-en-Y gastric bypass (RYGB) in HP-negative (HP-) and HP-eradicated (HPe) patients during five years follow-ups. METHODS This retrospective cohort study was conducted on 305 patients aged 18 and more with severe obesity, who underwent primary RYGB from February 2014 to November 2017. The HP-negative and HP-eradicated patients were evaluated for weight loss outcomes during five years follow-ups. RESULTS Patients' mean age, mean weight, and mean body mass index were 38.78 ± 9.9, 114.8 ± 13.6, and 43.37 ± 2.55, respectively. 27.2% of patients who were HP-positive were treated before RYGB. There was no significant difference between the HP- and HPe patients in terms of total weight loss percent (%TWL), 12 to 60 months after RYGB. Excess weight loss percent (%EWL) was higher in HPe patients compared to HP- patients (P = 0.04) at 12-month after RYGB. However, there was no difference in %EWL between these two groups of patients, 36 and 60 months after RYGB. CONCLUSION The results of the present study showed that TWL% had no significant difference in HP- and HPe groups during five years follow-ups after RYGB. The %EWL was higher in HPe patients only at 12 months after RYGB and the difference did not persist over time.

Abstract
The association between Helicobacter pylori (H. pylori) infection and coronary heart disease (CHD) remains controversial, with an unclear causal link. This study employed bidirectional Mendelian randomization (MR) method, using H. pylori infection as the exposure, to investigate its causal relationship with CHD diagnosis, prognosis, and potential pathogenesis. H. pylori infection exhibited a causal association with body mass index (BMI) (β = 0.022; 95% CI 0.008-0.036; p = 0.001). Conversely, there was no discernible connection between H. pylori infection and the diagnosis of CHD (OR = 0.991; 95% CI 0.904-1.078; p = 0.842; IEU database; OR = 1.049; 95% CI 0.980-1.118; p = 0.178; FinnGen database) or CHD prognosis (OR = 0.999; 95% CI 0.997-1.001; p = 0.391; IEU database; OR = 1.022; 95% CI 0.922-1.123; p = 0.663; FinnGen database). Reverse MR analysis showed no causal effect of CHD on H. pylori infection. Our findings further support that H. pylori infection exerts a causal effect on CHD incidence, mediated by BMI. Consequently, eradicating or preventing H. pylori infection may provide an indirect clinical benefit for patients with CHD.

Abstract
We aimed to assess the impact of Helicobacter pylori infection on postoperative outcomes following laparoscopic sleeve gastrectomy (LSG). We searched Cochrane, Scopus, and PubMed databases, reviewed 1026 studies, and thoroughly analyzed 42 of them. Our final analysis included 13 studies comprising 6199 patients. We found that H. pylori infection was correlated with higher rates of risk of overall postoperative complications (OR 1.56; 95% CI 1.13, 2.16; P = 0.007) and staple line leak (OR 1.89; 95% CI 1.05, 3.41; P = 0.03). There were no significant differences in hospital length of stay or postoperative bleeding rates. Despite observed correlations between H. pylori positivity in gastric specimen and postoperative complications in LSG, definitive causation remains elusive, emphasizing the need for prospective randomized studies evaluating the effect of preoperative H. pylori screening and eradication.

Abstract
Background and Aims Modern populations are prone to obesity, as sedentary lifestyles prevail globally. Previous research has shown that obesity and Helicobacter pylori are mutually associated. However, the global prevalence of H. pylori among individuals with obesity is not yet determined. Methods A comprehensive search will be conducted in PubMed, Scopus, and Web of Science online databases for studies that have reported the prevalence of H. pylori infection among individuals with obesity. Cross-sectional, case-control, and cohort studies will be included if reported sufficient data. Records screening, data extraction, and quality assessment will be done by independent reviewers. Joanna Bridge Institute checklist for prevalence studies will be used to appraise the included studies. Prevalence will be pooled using random effect models. Heterogeneity will be quantified by I 2 and p value. Subgroup analyses and meta-regression will be utilized to address the sources of residual between-study heterogeneity. Discussion Understanding the regional and global occurrence of H. pylori infection in individuals with obesity can provide valuable insights for health policymakers and clinicians to devise proficient diagnostic and eradication strategies, thereby enhancing postoperative outcomes for patients undergoing bariatric surgery. The study's strength will lie in not being restricted to language and time of publication, comprehensive investigation of regional and pre- and posteradication estimates, and the effects of time trends and sociodemographic indices on H. pylori prevalence. However, potential heterogeneity in methodologies used across prevalence studies could affect the interpretation of the results. Additionally, the study relies on previously published studies, limiting data quality and completeness.

Abstract
OBJECTIVES Inconsistent evidence currently exists regarding the associations between Helicobacter Pylori (H. pylori) infection and body mass index (BMI). The goal of the current study was to examine independent associations of H. pylori immunoglobulin G (IgG) seropositivity and BMI in a U.S.-based population sample. METHODS The US National Health and Nutrition Examination Survey (NHANES) with 2,576 subjects from 1999 to 2000 were analyzed. Using multivariate logistic regression models, associations between H. pylori IgG seropositivity and BMI were calculated after potential confounders were taken into account. Subgroup analyses were conducted furtherly stratified by sex, age, and race. RESULTS H. pylori IgG seropositivity was not associated with BMI in the general population (OR = 0.998; 95% CI = 0.977-1.019; P = 0.842). In the subgroup analyses stratified by race, a negative correction was found between the H. pylori IgG seropositivity and BMI among other races (OR = 0.873; 95% CI = 0.795-0.959; P = 0.004) except non-Hispanic white (OR = 1.006, 95% CI 0.966 to 1.048, P = 0.762), non-Hispanic black (OR = 1.021, 95% CI 0.979 to 1.065, P = 0.335), and Mexican American (OR = 1.010, 95% CI 0.966 to 1.055, P = 0.665). CONCLUSIONS In the general population, H. pylori IgG seropositivity is not associated with increased BMI, which provides a new perspective on obesity management.

Abstract
Background Helicobacter pylori (H. pylori) is a group 1 carcinogen and the etiological agent of gastric diseases such as gastritis, ulcers, and gastric cancer. It infects approximately half of the world's population. Risk factors associated with H. pylori infection include socioeconomic status, lifestyle, and diet. Objectives This study aimed to evaluate the association between eating habits and H. pylori infection in patients from a reference hospital in Central Brazil. Design This cross-sectional study included 156 patients from 2019 to 2022. Methods Data were collected using a structured questionnaire on sociodemographic and lifestyle characteristics and a validated food frequency questionnaire. The H. pylori infection status (positive versus negative) was determined using the histopathological method. After grams/day, foods were stratified into tertiles of consumption (low, medium, and high). Simple and multiple binary logistic regression models were used in the analysis of odds ratios (ORs) and their respective 95% confidence intervals (CIs), with a 5% significance level. Results The prevalence of H. pylori infection was 44.2% (69/156 patients). Infected individuals had a mean age of 49.6 ± 14.6 years; 40.6% were men, 34.8% were aged 60 years or older, 42.0% were unmarried, 7.2% had higher education, 72.5% were non-white, and 30.4% were obese. In the H. pylori-positive group, 55.1% were alcohol drinkers and 42.0% were smokers. The results of multiple analyses showed that the chance of H. pylori infection was higher among male participants (OR = 2.25; CI = 1.09-4.68) and individuals with obesity (OR = 2.68; CI = 1.10-6.51). Participants with moderate consumption of refined grains (bread, cookies, cakes, breakfast cereal) (OR = 2.41; CI = 1.04-5.62) and fruits (OR = 2.53; CI = 1.08-5.94) were more likely to be infected. Conclusion In this study, male sex, obesity, and the consumption of refined grains and fruits were positively associated with H. pylori infection. Further research is needed to investigate this association and elucidate the underlying mechanisms.

Abstract
Probiotics are defined as live microbial food elements that are beneficial to human health. Lacticaseibacillus casei T1 was considered to have potential as a bioactive ingredient in functional foods, which was isolated from kurut. Previous research by our group proved that L. casei T1 could prevent inflammatory responses caused by Helicobacter pylori. This study aimed to investigate whether treatment with L. casei T1 resulted in a suppressive effect on H. pylori-induced oxidative stress and inflammatory responses. The results showed that treatment with L. casei T1 could relieve H. pylori-induced overexpression of inflammatory cytokines in GES-1 cells. Experiments in animals suggested that taking long-term L. casei T1 could reduce oxidative stress and inflammatory cytokines and improve H. pylori-induced gastric mucosal damage. Furthermore, taking L. casei T1 could increase the relative abundance of beneficial intestinal bacterium (Lachnospiraceae and Odoribacter) of H. pylori-infected mice and help in maintaining the balance of intestinal microflora.Collectively, L. casei T1 had certain degrees of therapeutic effect against H. pylori. In the future, it combined with antibiotics for H. pylori eradication deserves further study.

Abstract
The rate at which obesity is becoming an epidemic in many countries is alarming. Obese individuals have a high risk of developing elevated intraocular pressure and glaucoma. Additionally, glaucoma is a disease of epidemic proportions. It is characterized by neurodegeneration and neuroinflammation with optic neuropathy and the death of retinal ganglion cells (RGC). On the other hand, there is growing interest in microbiome dysbiosis, particularly in the gut, which has been widely acknowledged to play a prominent role in the etiology of metabolic illnesses such as obesity. Recently, studies have begun to highlight the fact that microbiome dysbiosis could play a critical role in the onset and progression of several neurodegenerative diseases, as well as in the development and progression of several ocular disorders. In obese individuals, gut microbiome dysbiosis can induce endotoxemia and systemic inflammation by causing intestinal barrier malfunction. As a result, bacteria and their metabolites could be delivered via the bloodstream or mesenteric lymphatic vessels to ocular regions at the level of the retina and optic nerve, causing tissue degeneration and neuroinflammation. Nowadays, there is preliminary evidence for the existence of brain and intraocular microbiomes. The altered microbiome of the gut could perturb the resident brain-ocular microbiome ecosystem which, in turn, could exacerbate the local inflammation. All these processes, finally, could lead to the death of RGC and neurodegeneration. The purpose of this literature review is to explore the recent evidence on the role of gut microbiome dysbiosis and related inflammation as common mechanisms underlying obesity and glaucoma.

DO HELICOBACTER PYLORI INFECTION AND ERADICATION THERAPY STATUS INFLUENCE WEIGHT LOSS OUTCOMES AND ENDOSCOPIC FINDINGS AFTER ROUX-EN-Y GASTRIC BYPASS?A HISTORICAL COHORT STUDY. ARQUIVOS DE GASTROENTEROLOGIA 2023; 60:57-64.

Abstract
BACKGROUND Currently, there is conflicting evidence linking Helicobacter pylori (HP) infection with weight loss and endoscopic findings after Roux-en-Y gastric bypass (RYGB). OBJECTIVE To identify correlations between HP infection and its eradication with weight loss and endoscopic findings after RYGB. METHODS This is an observational retrospective cohort study based on a prospectively collected database of individuals who underwent RYGB from 2018-2019 at a tertiary university hospital. HP infection and the HP eradication therapy outcomes were correlated with post-operative weight loss and endoscopic findings. Individuals were classified according to the status of HP infection into four groups: no infection; successful eradication; refractory infection; and new-onset infection. RESULTS Of 65 individuals, 87% were female and the mean age was 39±11.2 years. Body mass index significantly decreased from 36.2±3.6 to 26.7±3.3 kg/m2 one year after RYGB (P<0.0001). The percentage of total weight loss (%TWL) was 25.9±7.2% and the percentage of excess weight loss was 89.4±31.7%. HP infection prevalence decreased from 55.4% to 27.7% (p=0.001); 33.8% never had HP infection, 38.5% were successfully treated, 16.9% had refractory infection and 10.8 % had new-onset HP infection. %TWL was 27.3±7.5% in individuals who never had HP, 25.4±8.1% in the successfully treated, 25.7±5.2% in those with refractory infection, and 23.4±6.4% in the new-onset HP infection group; there were no significant differences among the four groups (P=0.6). Pre-operative HP infection significantly associated with gastritis (P=0.048). New-onset HP infections significantly associated with a lower frequency of jejunal erosions after surgery (P=0.048). CONCLUSION No effects of the HP infection on weight loss were identified in individuals undergoing RYGB. A higher prevalence of gastritis was observed in individuals with HP infection before RYGB. New-onset HP infection after RYGB was a protective factor for jejunal erosions.

Abstract
Background Chronic inflammation has been reported as one of the novel coronary heart disease (CHD) risk factors. Knowing that Helicobacter pylori (H. pylori) provokes a local inflammation, the relationship between H. pylori infection and cardiovascular disease (CVD) has received considerable attention. However, the attempt to demonstrate the association between H. pylori and specific cardiovascular disease risk factors is always a challenging issue due to the conflicting reports in the literatures. Methods We performed a cross-sectional study of 363 consecutive dyspeptic subjects in three reference health facilities in Cameroon from October 2020 to October 2021. Each participation gave a written consent and the study was approved by the local Ethical Committee. Check-up for cardiovascular disease (CVD) risk factors such as dyslipidemia-related parameters, obesity-related parameter, high blood pressure as well as H. pylori detection was done for each participant. Data was analyzed using SSPS statistical package. Results Helicobacter pylori infection was significantly associated with higher total cholesterol level (OR: 2.3324, p = 0.0002) and higher LDL cholesterol level (OR: 2.3096, p = 0.0006). The crude OR of H. pylori status on the prevalence of high body mass index (BMI) was 1.0813 (p = 0.7300) and the adjusted OR for confounding factors was 1.1785 (p = 0.5095). The strength of the association between H. pylori infection and blood pressure, shows an OR of 1.3807 (p = 0.2991), 1.0060 (p = 0.9855) and 1.4646 (p = 0.2694) for diastolic pressure, hypertension and high heart rate respectively, while that of systolic pressure was 0.8135 (p = 0.4952). H. pylori infection is associated with dyslipidemia in our milieu.

Abstract
Accumulating data emphasize a strong link between obesity and the severity of coronavirus disease-2019 (COVID-19), including mortality. Obesity interferes with several components of the immune system including lymphoid tissue's integrity, leukocytes' development and function, complement system's activation, and the coordination of innate and adaptive immune responses. Overall, obesity results in a less efficient immune response to infectious agents. Severe acute respiratory syndrome coronavirus 2 exploits this weakened immune system in people with obesity to precipitate COVID-19, and in some cases death. It is therefore the author's recommendation that obesity should be viewed as another form of acquired immunodeficiency syndrome and be treated with the appropriate seriousness. Unlike the previously described acquired immunodeficiency syndrome (AIDS) that is caused by the Human Immunodeficiency Virus (HIV), obesity is a comorbidity-acquired immunodeficiency syndrome. People with AIDS do not die from HIV, but may die from opportunistic pathogens such as Mycobacterium tuberculosis. However, AIDS is ascribed its due importance in the course of deterioration of the patient. Similarly, obesity should be acknowledged further as a risk factor for mortality from COVID-19. Obesity is a modifiable condition and even in people with a strong genetic predisposition, lifestyle modifications can reverse obesity, and even moderate weight loss can improve the inflammatory milieu. Strong public health actions are warranted to promote lifestyle measures to reduce the burden from overweight and obesity that currently affect more than one-third of the global population, with projections alarming this may reach 55-80% within the next thirty years.

Abstract
Helicobacter pylori (H. pylori) can be eradicated immediately while conducting an endoscopic examination. The eradication rate of intraluminal therapy for H. pylori infection (ILTHPI) is 53.7% (51/95) via local application of single-dose medicament containing amoxicillin, metronidazole, and clarithromycin. We aimed to evaluate factors affecting ILTHPI and to assess the efficacy among single antibiotics, and compared our results with combined antibiotics. We enrolled H. pylori-infected treatment-naïve symptomatic patients; 95 completed triple-antibiotic ILTHPI were evaluated for risk factors, along with 60 completed mono-antibiotic ILTHPI containing amoxicillin, clarithromycin, or metronidazole in each of the 20 patients. Univariate analysis revealed the significant influence of BMI (OR: 1.15; 95% CI: 1.03-1.27, p = 0.011) and gastric juice pH (OR: 1.35; 95% CI: 1.16-1.58, p = 0.0001). Logistic regression analysis also showed significant influence of gastric juice pH (OR: 1.30; 95% CI: 1.10-1.54, p = 0.002). The eradication rate of mono-antibiotic ILTHPI is significantly lower than triple-antibiotic ILTHPI (11.7% vs. 53.7%; p < 0.0001; α = 0.05, power = 1.0). The efficacy was 20% (4/20) for metronidazole, 10% (2/20) for amoxicillin, and 5% (1/20) for clarithromycin. In conclusion, the level of gastric juice pH is a crucial factor affecting the ILTHPI. The detection of gastric juice pH and selection of optimal intraluminal medicaments are important. Further studies with combined antibiotics for ILTHPI, perhaps metronidazole-containing medicaments, are recommended.

Abstract
Helicobacter pylori (H. pylori) infection is one of the most common in the world. More than 50% of the world’s population is infected and infection rates are especially high in countries with poor socio-economic conditions. H. pylori causes gastroduodenal and extra-gastroduodenal diseases including such metabolic disorders as obesity, diabetes mellitus and non-alcoholic fatty liver disease. Recent epidemiological and clinical studies showed that the long-term persistence of H. pylori infection is associated with the development and progression of atherosclerosis and consequently cardiovascular diseases. However, the correlation between these conditions is ambiguous and there is not enough evidence to confirm it. The lack of consensus might be related to differences in diagnostic methods used for H. pylori and the variety of its genotypes. Considering high prevalence of H. pylori infection as well as high incidence of metabolic and cardiovascular diseases, a verified correlation between these can be of great epidemiological, prophylactic and clinical significance.

Abstract
Helicobacter pylori is a causative pathogen of many gastric and extra-gastric diseases. It has infected about half of the global population. There were no genome-wide association studies (GWAS) for H. pylori infection conducted in Chinese population, who carried different and relatively homogenous strain of H. pylori. In this work, we performed SNP (single nucleotide polymorphism)-based, gene-based and pathway-based genome-wide association analyses to investigate the genetic basis of host susceptibility to H. pylori infection in 480 Chinese individuals. We also profiled the composition and function of the gut microbiota between H. pylori infection cases and controls. We found several genes and pathways associated with H. pylori infection (P < 0.05), replicated one previously reported SNP rs10004195 in TLR1 gene region (P = 0.02). We also found that glycosaminoglycan biosynthesis related pathway was associated with both onset and progression of H. pylori infection. In the gut microbiome association study, we identified 2 species, 3 genera and several pathways had differential abundance between H. pylori infected cases and controls. This paper is the first GWAS for H. pylori infection in Chinese population, and we combined the genetic and microbial data to comprehensively discuss the basis of host susceptibility to H. pylori infection.

Abstract
INTRODUCTION The relationship between H. pylori infection and obesity development has remained controversial among various studies. The aim of this study was to clarify the pooled effect of H. pylori infection on the development of obesity and vice versa. METHODS We searched international databases including Medline (PubMed), Web of sciences, Scopus, EMBASE, Cochrane, Ovid, and CINHAL to retrieve all case-control studies reporting the effect of H. pylori on obesity and vice versa, which had been published in English between January 1990 and June 2019. The quality of included studies was assessed by the Modified Newcastle-Ottawa Scale for Case-Control studies. The logarithm of the odds ratio (OR) and its standard error was used for the meta-analysis. RESULTS Eight case-control studies with 25,519 participants were included for qualitative and quantitative analyses. The pooled analysis showed that obese participants had a higher risk of H. pylori infection than lean participants with an odds ratio of 1.46 (95%CI: 1.26, 1.68). Also, the pooled analysis revealed that participants infected by H. pylori had a higher risk of obesity than non-infected participants with an odds ratio of 1.01 (95%CI: 1.01, 1.02). CONCLUSION The results of this meta-analysis showed that there was a positive correlation between the risk of H. pylori infection and the prevalence of obesity development. Thus, H. pylori positive patients were more likely to be obese, and obese individuals had higher risks of H. pylori infection.

Abstract
Emerging data suggest an association between obesity and infectious diseases. Although the mechanisms underlying this link are not well established, a number of potential factors may be involved. Indeed, the obesity-related vulnerability to infectious diseases could be due to chronic low-grade inflammation, hyperglycemia, hyperinsulinemia, and hyperleptinemia, which lead to a weakening of both the innate and adaptive immune responses. In addition, obesity results in anatomical-functional changes by the mechanical obstacle of excessive adipose tissue that blunt the respiratory mechanisms and predisposing to respiratory infections. Subjects with obesity are also at risk of skin folds and sweat more profusely due to the thick layers of subcutaneous fat, favoring the proliferation of microorganisms and slowing the repair of wounds down. All these factors make subjects with obesity more prone to develop nosocomial infections, surgical site, skin and soft tissue infections, bacteremia, urinary tract infections, and mycosis. Furthermore, infections in subjects with obesity have a worse prognosis, frequently prolonging hospitalization time as demonstrated for several flu viruses and recently for COVID-19. Thus, the aim of this manuscript is to provide an overview of the current clinical evidence on the associations between obesity and infectious diseases highlighting physio pathological insights involved in this link.

Abstract
OBJECTIVES Severe obesity in the pediatric population has lifelong consequences. Bariatric surgery has been suggested for selected adolescents with severe obesity after careful evaluation. The indications for preoperative esophagogastroduodenoscopy (EGD) in this age group are not clear, despite its established usefulness in adults. We aimed to assess the usefulness of EGD before bariatric surgery in pediatric patients with severe obesity and metabolic comorbidities. METHODS We conducted a retrospective chart review in a single tertiary pediatric medical center of adolescents treated during 2011 to 2018. Data collected from electronic medical records included patient demographics, endoscopic findings, and laboratory parameters. RESULTS A total of 80 patients (40 boys) underwent evaluation. Macroscopic abnormalities were detected in 54% of the endoscopies, including gastritis, esophagitis, and duodenitis in 46%, 16%, and 13%, respectively. Forty-nine percentage of the biopsies showed histological abnormalities; in 35 (44%) patients, Helicobacter pylori was detected. Thirty-three patients (41%) received medical treatment and 2 (2.5%) required a second EGD. Metabolic comorbidities included hypertriglyceridemia (38% of the patients), low high-density lipoprotein (23%), and prediabetic (16%) or diabetic levels of HbA1C (4%). Fifty-five percentage of the cohort had elevated alanine aminotransferase (ALT), suggestive of nonalcoholic fatty liver disease (NAFLD). CONCLUSIONS Endoscopies performed before bariatric surgeries suggest a higher prevalence of clinically significant findings, many of which required treatment. These findings support incorporating an EGD into the preoperative evaluation of this patient population.

Abstract
Helicobacter pylori (H. pylori) is a gram-negative bacterium that infects approximately 4.4 billion individuals worldwide. Although the majority of infected individuals remain asymptomatic, this bacterium colonizes the gastric mucosa causing the development of various clinical conditions as peptic ulcers, chronic gastritis and gastric adenocarcinomas and mucosa-associated lymphoid tissue lymphomas, but complications are not limited to gastric ones. Extradigestive pathologies, including metabolic disturbances such as diabetes, obesity and nonalcoholic fatty liver disease, have also been associated with H. pylori infection. However, the underlying mechanisms connecting H. pylori with extragastric metabolic diseases needs to be clarified. Notably, the latest studies on the topic have confirmed that H. pylori infection modulates gut microbiota in humans. Damage in the gut bacterial community (dysbiosis) has been widely related to metabolic dysregulation by affecting adiposity, host energy balance, carbohydrate metabolism, and hormonal modulation, among others. Taking into account that Type 2 diabetic patients are more prone to be H. pylori positive, gut microbiota emerges as putative key factor responsible for this interaction. In this regard, the therapy of choice for H. pylori eradication, based on proton pump inhibitor combined with two or more antibiotics, also alters gut microbiota composition, but consequences on metabolic health of the patients has been scarcely explored. Recent studies from our group showed that, despite decreasing gut bacterial diversity, conventional H. pylori eradication therapy is related to positive changes in glucose and lipid profiles. The mechanistic insights explaining these effects should also be addressed in future research. This review will deal with the role of gut microbiota as the linking factor between H. pylori infection and metabolic diseases, and discussed the impact that gut bacterial modulation by H. pylori eradication treatment can also have in host's metabolism. For this purpose, new evidence from the latest human studies published in more recent years will be analyzed.

Adenovirus 36 prevalence and association with human obesity: a systematic review. Int J Obes (Lond) 2021; 45:1342-1356. [PMID: 33753885 PMCID: PMC7983349 DOI: 10.1038/s41366-021-00805-6] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 02/01/2021] [Accepted: 03/04/2021] [Indexed: 01/31/2023]
Abstract
INTRODUCTION Obesity has numerous etiologies and includes biological factors. Studies have demonstrated that the human adenovirus subtype 36 (Adv36) is an adipogenic agent and causes metabolic alterations. Study results on the prevalence of Adv36 and clinical effects in humans vary substantially. This was a systematic review to summarize the studies on the prevalence of Adv36 infection and its association with human obesity. METHODS A systematic literature review was conducted using the preferred reporting items for systematic reviews and meta-analysis (PRISMA). Observational or experimental studies found in the Medline, Embase, LILACS, Science Direct and SciELO databases that presented results on the prevalence of Adv36 in humans were included. RESULTS Thirty-seven studies were screened. A total of 10,300 adults aged 18-70 years and 4585 children and adolescents aged 3-18 years were assessed. The average prevalence of Adv36 among adults was 22.9%, ranging from 5.5% to 49.8%. Among children and adolescents, the average prevalence of Adv36 was 28.9%, ranging from 7.5% to 73.9%. There was a positive statistical relationship between Adv36 and weight gain, obesity, or metabolic changes in 31 studies. However, in four studies there was no association with obesity, and in one, no association was described. One of the studies showed an inverse correlation, i.e., Adv36 was a protective factor against obesity. CONCLUSION Strong evidence suggested a positive association between viral infection and obesity. However, due to the multi-causality of obesity and heterogeneity of studies, diagnostic tests should be standardized and easily accessible by the population to estimate the overall prevalence of Adv36 infection and its association with obesity.

Abstract
BACKGROUND The reduction in the prevalence of Helicobacter pylori (H. pylori) infection in developed countries coincides with the increasing incidence of obesity and might be a contributing factor to the obesity epidemic. We aimed to evaluate the association between H. pylori infection and childhood overweight/ obesity in Israeli children. MATERIAL AND METHODS Patients diagnosed with H. pylori infection by endoscopy, histology, and a positive culture, between January 2013 and August 2018, were identified and compared with H. pylori-negative children, of the same age and gender, undergoing endoscopy for the same indications during the same time period. Data collected included the following: age, gender, height, weight, BMI, BMI percentile, and the indication for endoscopy. Patients with missing anthropometric data or having a disease affecting growth were excluded. RESULTS We included 146 H. pylori-positive children and 146 age- and gender-matched H. pylori-negative patients. 63.7% (186/292) were female, mean age 13.1 ± 3.7. Overweight (BMI between the 85th-95th percentile) and obesity (BMI > 95th percentile) were present in 56/292 (19.2%). Among the H. pylori-positive children, 11.6% were overweight, 7.5% obese, among the H. pylori-negative children, 10.3% were overweight, 8.9% obese, demonstrating no differences between the groups. The main indication for endoscopy was abdominal/ epigastric pain in 79.8% (233/292). The percent of children with a BMI ≥ 85% did not differ by gender age or the indication for endoscopy. CONCLUSIONS No association between H. pylori infection and childhood overweight/ obesity was demonstrated. This is in contrasts with previous pediatric studies demonstrating an inverse correlation.

Abstract
INTRODUCTION Helicobacter pylori (H. pylori) is a type of bacteria that affects more than half of the world's population and has been associated with gastritis. The relationship between H. pylori and obesity is controversial. Laparoscopic sleeve gastrectomy (LSG) is the most commonly used surgery for morbidly obese patients. The aim of this study was to investigate the rate of H. pylori in patients undergoing LSG. METHODS Biopsy specimens of 32,743 patients who underwent esophagogastroduodenoscopy (EGD) and resection materials from 1257 patients who underwent LSG were examined histopathologically. The relationships between body mass index (BMI), age, gender, H. pylori infection, and intestinal metaplasia (IM) were investigated in patients with gastritis. RESULTS In patients undergoing EGD, the association of H. pylori infection was found to be increased in males and the elderly (p < 0.001). The presence of gastritis and IM was significantly higher with H. pylori infection (p < 0.001 and p = 0.001, respectively). H. pylori infection was significantly higher in patients over the age of 41 years (p < 0.001). There was no significant difference between the results of H. pylori before and after LSG surgery (p = 0.923). The presence of H. pylori together with gastritis and IM was found to be significant (p < 0.001). CONCLUSIONS H. pylori infection increases with age. No significant difference was found in the examination for H. pylori before and after LSG surgery. In addition, no relationship was found between H. pylori and excess weight. However, due to the low average age of patients who underwent LSG, further studies are needed in this area.

Abstract
The impact of sex-specific body fat distribution on the susceptibility to five chronic infections, helicobacter pylori and human herpesviruses 3 to 6 (i.e. varicella-zoster, Epstein-Barr, cytomegalo- and human herpesvirus 6), has not previously been examined. In the present study, seropositivity was determined via multiplex serology in serum samples of study participants collected in 2006/08 and 2013/14 during the follow-up examinations F4 (n = 3080) and FF4 (n = 2279) of the German population-based baseline KORA S4 survey. We quantified the severity of overall and abdominal obesity by body mass index, body adiposity index, waist circumference, waist-to-hip ratio, and waist-to-height ratio. Using sex-specific logistic spline-models, cross-sectional and longitudinal associations between obesity measures and seropositivity of the previously mentioned infections were investigated. Overall and abdominal fat content were significantly associated with seropositivity of varicella-zoster virus in both cross-sectional and longitudinal analyses among women. In addition, a non-significant inverse relationship with Epstein-Barr virus seroprevalence in both sexes and a trend towards a positive association with human herpesvirus 6 seropositivity in women were observed. Therefore, in women total body fat may be associated with VZV-seropositivity and may influence the reactivation of the varicella-zoster virus, independent of adipose tissue distribution.

Abstract
BACKGROUND Adult undernutrition (BMI <18.5 kg/m2) is responsible for immune deficits, increased risk of disease burden, and higher rates of mortality. The prevalence of adult undernutrition in Bangladesh is substantial, but there have been few studies on the etiology of this condition for the inhabitants of urban slums. OBJECTIVE The aim of this study was to identify the factors associated with undernutrition among slum-dwelling adults in Bangladesh. METHODS A case-control study was conducted in the Bauniabadh area of Dhaka, Bangladesh. 270 adult participants (135 cases with a BMI <18.5 and 135 controls with a BMI between 18.5 and 24.9) aged 18-45 y were enrolled between October 2018 and January 2019. Sociodemographic variables, dietary diversity, micronutrient deficiencies, psychological symptoms, infection, and biomarkers of gut health were assessed to identify the factors associated with undernutrition using multivariable logistic regression analysis. RESULTS A higher number of siblings [adjusted odds ratio (aOR): 1.39; 95% CI: 1.11, 1.77], increased self-reporting questionnaire-20 score (an instrument to screen mental health disorders and detect psychological symptoms) (aOR: 1.12; 95% CI: 1.04, 1.23), elevated fecal concentration of α-1 antitrypsin (aOR: 4.82; 95% CI: 1.01, 25.29), and anemia (aOR: 3.63; 95% CI: 1.62, 8.58) were positively associated with undernutrition in adults. Age (aOR: 0.90; 95% CI: 0.84, 0.96), dietary diversity score (aOR: 0.75; 95% CI: 0.56, 0.99), C-reactive protein (aOR: 0.82; 95% CI: 0.73, 0.92), Helicobacter pylori infection (aOR: 0.11; 95% CI: 0.05, 0.23), and always washing hands before eating or preparing foods (aOR: 0.33; 95% CI: 0.12, 0.87) were associated with reduced odds of undernutrition among the study population. CONCLUSIONS Our results indicate that undernutrition in slum-dwelling adults in Bangladesh is associated with numerous physiological and sociodemographic factors, including evidence of gastrointestinal inflammation and altered intestinal permeability.

Abstract
Background Helicobacter pylori is a common cause of gastritis, peptic ulcer disease, and non-ulcer dyspepsia, and is also associated with gastric adenocarcinoma and mucosa associated lymphoid tissue lymphoma. Despite being known about for more than 30 years, finding an effective therapeutic strategy against it remains a challenge. Aim There are no US studies evaluating the efficacy of a Levofloxacin based therapy for H. pylori infection. We here intend to study the efficacy of Levofloxacin based triple antibiotic regimen as compared to Clarithromycin based triple therapy and Bismuth based quadruple therapy in our patient population. Methods This is a retrospective single center observational study. Patients with Helicobacter pylori infection who underwent treatment for H. pylori with one of the three therapies, i.e. Clarithromycin triple, Bismuth Quadruple or Levofloxacin triple, were included in the study and the eradication rates were compared. The confirmation of the H. pylori was done 4 weeks after the completion of anti-microbial therapy. Results A total of 177 individuals underwent the H. pylori treatment in our retrospective review. Of these, 54% (n=97) of patients were treated with Clarithromycin based triple therapy (Group 1), 35% (n=63) were treated with Levofloxacin based regimen (Group 2), and the remaining 11% (n=17) were treated with Bismuth based quadruple therapy (Group 3). The eradication rates were significantly higher in patients treated with Clarithromycin based triple therapy as compared to Levofloxacin based triple therapy and Bismuth quadruple therapy (78.3% vs 49.2% vs 41.1% P=0.001). Conclusion In conclusion, our study shows significantly lower eradication rates with Levofloxacin triple therapy among a selected US population. Thus, it may not be a good first-line therapy among this US population and the Clarithromycin based regimen may still be used successfully.

Abstract
PURPOSE The cellular distribution of ghrelin positive cells is not well defined. The aim of the study is to quantify and determine the distribution of ghrelin cells in gastric mucosa in patients with morbid obesity and relate this finding to gender, comorbidities, gastritis, and plasmatic levels of acyl and desacylghrelin before and after laparoscopic sleeve gastrectomy. PATIENT AND METHODS We performed a study on 61 patients with BMI≥50 kg/m2 operated by laparoscopic sleeve gastrectomy. Three gastric regions were analyzed by histopathology and immunohistology. Blood sample was taken before surgery, and at 6 and 12 months post-surgery, to study the plasma levels of ghrelin isoforms. RESULTS Ghrelin cells are present in all regions of the gastric mucosa, with a greater number in the body and the fundus. Difference was found in the antrum between male and female patients (p=0.018). Patients with arterial hypertension also showed a lower level of cells in antrum (p<0.05). Acylghrelin levels after surgery were significantly lower (32.83+5.6 pg/mL to 10.09+11.8 pg/mL, p<0.05). Values of desacylghrelin tended to decrease but no significant variation was observed (207.4+39.3 pg/mL to 188.84+52.3 pg/mL). CONCLUSION Our patients show ghrelin cells in all areas of the stomach. Gender, comorbidities, and gastritis are determinant on gastric ghrelin-producing cells distribution.

Abstract
AıM: To determine the prevalence of histopathological findings requiring clinical follow-up in morbidly obese patients undergoing laparoscopic sleeve gastrectomy (LSG) and evaluate the relationship between these findings and Helicobacter pylori as well as to add more data to the published literature in this regard. MATERıAL AND METHODS: Overall, 161 morbidly obese patients with body mass index (BMI) > 40 kg/m2 who underwent LSG between May 1, 2014 and May 31, 2017 were retrospectively included in the study. The findings of the histopathological evaluation of the resected gastric material and the relationship between these findings and histopathologically detected H. pylori infection were investigated. RESULTS The study included 114 women (70.8%) and 47 men (29.2%). The mean age of the patients was 36.82 ± 10.41 years, and the mean BMI was 46.05 ± 3.76 kg/m2. H. pylori infection was detected in 103 (64%), chronic gastritis in 156, chronic active gastritis in 47, intestinal metaplasia in eight, and atrophy in seven patients. The rate of H. pylori-associated chronic gastritis was 64%, that of chronic active gastritis was 24.2%, that of lymphoid aggregation was 62.2%, and that of intestinal metaplasia and atrophy was 3.1%. There was a significant relationship between H. pylori infection and chronic gastritis, chronic active gastritis, and lymphoid aggregation; however, no significant relationship was found between intestinal metaplasia and atrophy. CONCLUSıON: Clinicians should be aware of the histopathological findings requiring clinical follow-up for LSG-treated patients. Given the complications of H. pylori infection such as lymphoma and malignancy, periodic follow-up of patients and eradication therapy may be a suitable approach for treating intestinal metaplasia and atrophic changes.

Abstract
BACKGROUND Obesity is highly prevalent worldwide. More and more studies have been conducted on the relationship between H. pylori infection and obesity or overweight. But the relationship between them is controversial in the literatures and there is no comprehensive evidence for the correlation. AIM To evaluate the prevalence of H. pylori infection in Chinese adult subjects who received routine physical examinations and the relationship between H. pylori and obesity. METHODS Literatures on H. pylori infection and obesity in Chinese population were searched in online databases. Relevant data were extracted independently by two researchers and meta-analysis was performed by using Review manager 5.3 software. RESULTS 22 articles were selected with a total sample size of 178033. The pooled prevalence of H. pylori was 42% (95%CI: 37% to 47%) and mean difference of BMI between subjects with and without H. pylori infection was 0.94 (95%CI: -0.04 to 1.91). 9 eligible studies with 27111 subjects were used to calculated pooled OR value because they contained obesity groups. The OR value showed that H. pylori-positive subjects tended to be obese at a risk of 1.20 (95% CI: 1.13 to 1.28). CONCLUSION In China, obesity has association with H. pylori infection. H. pylori infection may be one of the risk factors for obesity.

Abstract
Helicobacter pylori (HP) is a gram-negative flagellated pathogen acid-resistant bacterium; it belongs to the order Campylobacterales that is wide spread all over the world, infecting more than 50% of the world population. HP infection is etiologically associated with non-atrophic and atrophic gastritis, peptic ulcer and with 3 to 6-fold increased relative risk for developing gastric adenocarcinoma and mucosa-associated lymphoid tissue (MA LT) lymphoma. For this reason HP is recognized by the World Health Organization as a Class I human carcinogen. In the last years a lot of studies clarified the role of this pathogen in nutrition and metabolism; particularly, it has been shown that it is able to induce malabsorption of several nutrients like iron, cobalamin, vitamin C and vitamin E, with strong consequences on nutritional status. Interesting, this bacterium is able to produce different biological effects on hormones like ghrelin and leptin controlling both appetite and growth, mostly depending on the time of acquisition of the infection and of its treatment. In this review, the authors focused their attention on nutritional effects of HP infection and particularly on the role that diet, food, plants and specific nutrients can play in its treatment, considering that HP eradication rates, with standard triple-therapy, have fallen to a low level in the last years.

Abstract
Objective: We examine obese and non-obese patients with respect to Helicobacter pylori (H. pylori) positive-infection (HPPI) and associated factors, specifically body mass index (BMI). Methods: This study took place in the Department of Endoscopy of a central hospital in the Najran region of Saudi Arabia (SA). A total of 340 obese Saudi patients (BMI ≥ 30 kg/m2) who had undergone diagnostic upper endoscopy before sleeve gastrectomy, were compared with 340 age and gender-matched control patients (BMI < 30 kg/m2) who had undergone diagnostic upper endoscopy for other reasons. Data collected included diagnosis of HPPI. Descriptive and multivariable binary logistic regression was conducted. Results: Mean patient age was 31.22 ± 8.10 years, and 65% were males. The total prevalence of HPPI was 58% (95% CI = 54–61%) with obese patients presenting significantly more HPPI than non-obese patients (66% vs. 50%, OR = 1.98, 95% CI = 1.45–2.70, p < 0.0005). Age and gender did not associate significantly with HPPI (p = 0.659, 0.200, respectively) and increases in BMI associated significantly with increases in HPPI (p < 0.0005). BMI remained a significant factor in HPPI when modelled with both age and gender (OR = 1.022, 95% CI = 1.01–1.03, p < 0.0005). Conclusions: Within the limitations of this study, the significance of HPPI in obese Saudi patients residing in the Najran region in SA was demonstrated alongside the significance role of BMI in HPPI.

Abstract
BACKGROUND Whether high body mass index (BMI) was associated with increased postoperative complications and unfavorable prognosis of gastric cancer (GC) patients remain controversial. In the present study, we performed a systematic review and meta-analysis to evaluate the impact of high BMI on surgical outcome, postoperative complications and long-term survival of GC patients. METHODS The related studies were identified by searching PubMed and Embase databases. According to the BMI, all GC patients were classified into BMI ≥25 kg/m2 group and BMI <25 kg/m2 group. The relevant data was extracted and pooled effect size was assessed using a fixed effect model or random effect model. RESULTS A total of 36 relevant studies involving 30,642 GC patients were included in this meta-analysis. The results indicated that high BMI patients had longer operation time, fewer number of retrieved lymph nodes and larger amount of intraoperative blood loss than other patients, regardless of open gastrectomy or laparoscopic gastrectomy. In addition, the risk of postoperative complications was significantly higher in the patients with BMI ≥25 kg/m2 than in those with BMI <25 kg/m2, especially for infectious complications. However, high BMI had no negative impact on postoperative mortality and long-term survival of GC patients. CONCLUSION Despite the increased surgical difficulty and postoperative complications, high BMI was not associated with the prognosis of GC patients. To reduce the risk of postoperative complications, more meticulous operation technique and improved perioperative management should be necessary for high BMI patients.

Abstract
Helicobacter pylori (H. pylori) infection can induce chronic inflammation and is associated with insulin resistance, metabolic syndrome and body mass index (BMI, kg/m2) changes. This study aimed to evaluate the association between H. pylori infection and overweight/obesity. This research was a cross-sectional study conducted from March 2014 to November 2016, using data from the three districts in the northeastern region of Taiwan. The inclusion criteria were an age >30 years and the absence of pregnancy. Ultimately, 2686 subjects (1713 women) were included in this study. Among the subjects aged less than 50 years, the subjects with H. pylori infection had higher mean BMI values than those without H. pylori infection (40-49 years: 25.7 ± 4.4 vs. 24.7 ± 3.8, P = 0.025; 30-39 years: 24.9 ± 4.4 vs. 24.0 ± 4.1, P = 0.063). H. pylori infection increased the risk of being obese 2 (BMI ≥30) (odds ratio, OR = 1.836, 95% CI = 1.079-3.125, P = 0.025) with adjustments for demographic factors in subjects aged less than 50 years. In conclusions, subjects with H. pylori infection and age less than 50 years may increase a risk of being obesity (BMI ≥30) compared to those without this type of infection.

Abstract
Immune cell function and metabolism are closely linked. Many studies have now clearly demonstrated that alterations in cellular metabolism influence immune cell function and that, conversely, immune cell function determines the cellular metabolic state. Less well understood, however, are the effects of systemic metabolism or whole organism nutritional status on immune cell function and metabolism. Several studies have demonstrated that undernutrition is associated with immunosuppression, which leads to both increased susceptibility to infection and protection against several types of autoimmune disease, whereas overnutrition is associated with low-grade, chronic inflammation that increases the risk of metabolic and cardiovascular disease, promotes autoreactivity, and disrupts protective immunity. Here, we review the effects of nutritional status on immunity and highlight the effects of nutrition on circulating cytokines and immune cell populations in both human studies and mouse models. As T cells are critical members of the immune system, which direct overall immune response, we will focus this review on the influence of systemic nutritional status on T cell metabolism and function. Several cytokines and hormones have been identified which mediate the effects of nutrition on T cell metabolism and function through the expression and action of key regulatory signaling proteins. Understanding how T cells are sensitive to both inadequate and overabundant nutrients may enhance our ability to target immune cell metabolism and alter immunity in both malnutrition and obesity.

Abstract
Existing explanations of obesity-associated cancer emphasise direct mutagenic effects of dietary components or hormonal imbalance. Some of these hypotheses are reviewed briefly, but recent evidence suggests a major role for chronic inflammation in cancer risk, possibly involving dietary content. These ideas include the inflammation-induced activation of the kynurenine pathway and its role in feeding and metabolism by activation of the aryl hydrocarbon receptor (AHR) and by modulating synaptic transmission in the brain. Evidence for a role of the kynurenine pathway in carcinogenesis then provides a potentially major link between obesity and cancer. A second new hypothesis is based on evidence that serine proteases can deplete cells of the tumour suppressors Deleted in Colorectal Cancer (DCC) and neogenin. These enzymes include mammalian chymotryptic proteases released by pro-inflammatory neutrophils and macrophages. Blood levels of chymotrypsin itself increase in parallel with food intake. The mechanistically similar bacterial enzyme subtilisin is widespread in the environment, animal probiotics, meat processing and cleaning products. Simple public health schemes in these areas, with selective serine protease inhibitors and AHR antagonists and could prevent a range of intestinal and other cancers.

Abstract
BACKGROUND Data on the association of Helicobacter pylori infection and BMI are conflicting. The fact that both H. pylori infection and BMI are associated with low socioeconomic status (SES) makes this relationship difficult to characterize. MATERIALS AND METHODS We aimed to evaluate the association between BMI and H. pylori infection after adjusting for multiple covariates. We analyzed a cohort of 235 107 individuals aged 18 years or older, who performed a C urease breath test (C-UBT), from 2007 to 2014. Data on BMI, age, sex, SES, ethnicity, and medications were extracted from a nationwide population-based database. BMIs were classified according to the WHO recommendations: underweight (<18.5 kg/m), normal weight (18.5-24.9 kg/m), overweight (25-29.9 kg/m), obese class I (30-34.9 kg/m), and obese class II or more (>35 kg/m). STUDY RESULTS The positivity rate for H. pylori among underweight, normal weight, overweight, and obese class I and class II or more was 55.6, 58.5, 63.0, 64.5, and 65.5%, respectively (P<0.001, Plinear trend 0.007). The association between BMI and H. pylori infection was significant across all SES, sex, ethnicity, and age categories. After adjusting for age, sex, ethnicity, and SES, being overweight and obese class I and class II or more were associated significantly with H. pylori positivity: odds ratio 1.13 [95% confidence interval (CI): 1.11-1.15], 1.14 (95% CI: 1.11-1.17), and 1.15 (95% CI: 1.11-1.19), respectively, P value less than 0.001 for all. CONCLUSION Among individuals who were referred to a C-UBT by primary care physician, after adjusting for multiple covariates including SES, we found a positive association between H. pylori infection and an increased BMI.

Abstract
Helicobacter pylori (HP) occurs in 50% of people worldwide with higher rates reported in the bariatric population. HP has been associated with adverse outcomes following bariatric surgery; however, its true impact has not yet been defined. We aimed to systematically review the effect of HP on bariatric surgery outcomes. A comprehensive literature review was conducted yielding seven studies with 255,435 patients. Meta-analysis found comparable rates of bleeding, leak, hospital length of stay, and weight loss between HP-positive and HP-negative patients. HP was, however, found to be the largest independent predictor of marginal ulceration in those undergoing RYGB, with a tenfold increase versus HP-negative patients. Overall, HP is associated with increased marginal ulceration rates, but has little impact on other bariatric surgery outcomes.

Abstract
PURPOSE To investigate the effect of Helicobacter pylori (H. pylori) infection on choroidal thickness (CT) and retinal nerve fiber layer thickness (RNFLT). METHODS The study included 25 patients with H. pylori infection and 25 healthy individuals as the control group. Helicobacter pylori patients were classified as the pre-treatment (Group 1; n: 25) and the post-treatment (Group 2; n: 25). RNFLT and CT were measured before and after treatment of H. pylori infection, using enhanced depth imaging (EDI) spectral-domain optical coherence tomography (Spectralis, Heidelberg Engineering, Heidelberg, Germany). The axial length and intraocular pressure were also measured. RESULTS The mean subfoveal CT was 320.96 ± 29.15 μm in Group 1 and 287.48 ± 49.17 in the control group (p = 0.007), while the mean subfoveal CT did not show any difference between Group 2 and the control group (p > 0.05). No statistically significant difference was determined between the H. pylori patients and the control group in respect of RNFLT values (p > 0.05). CONCLUSIONS CT increases during H. pylori infection and returns to the normal range within 6 weeks of treatment. RNFLT does not show any change during H. pylori infection. The data related to the subfoveal CT may be useful in understanding the pathogenesis of central serous chorioretinopathy developing in H. pylori patients.

Abstract
Obesity usually is associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause (eg, nonalcoholic fatty liver disease) or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease, erosive esophagitis, Barrett's esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including nonalcoholic fatty liver disease, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer. Gastroenterologists are uniquely poised to participate in the multidisciplinary management of obesity as physicians caring for people with obesity-related diseases, in addition to their expertise in nutrition and endoscopic interventions.

Abstract
AIM To explore the association between Helicobacter pylori (H. pylori) infection and obesity/weight gain in a Chinese population.
METHODS Our primary outcome was the change in body mass index (BMI). The generalized linear models were used to explore the association between H. pylori infection and the change of BMI, and the logistic regression models were used to explore the association between H. pylori infection and obesity.
RESULTS A total of 3039 subjects were recruited and analyzed, of which 12.8% were obese. The prevalence of H. pylori infection was 53.9% (1639/3039) overall and 54.6% (212/388) in the obese subjects. The change of BMI in the H. pylori (+) group was not significantly higher than that in the H. pylori (-) group after adjustment for potential confounding factors [RR = 0.988, 95%CI: 0.924-1.057, P = 0.729]. The prevalence of obesity decreased 1.1% in the H. pylori (+) group and 0.5% in the H. pylori (-) group. The RR of H. pylori infection for obesity was 0.831 (95%CI: 0.577-1.197, P = 0.321) after the adjustment.
CONCLUSION H. pylori infection was not associated with overweight/obesity observed from the retrospective study in this Chinese population.

Abstract
T cells are highly influenced by nutrient uptake from their environment, and changes in overall nutritional status, such as malnutrition or obesity, can result in altered T-cell metabolism and behavior. In states of severe malnutrition or starvation, T-cell survival, proliferation, and inflammatory cytokine production are all decreased, as is T-cell glucose uptake and metabolism. The altered T-cell function and metabolism seen in malnutrition is associated with altered adipokine levels, most particularly decreased leptin. Circulating leptin levels are low in malnutrition, and leptin has been shown to be a key link between nutrition and immunity. The current view is that leptin signaling is required to upregulate activated T-cell glucose metabolism and thereby fuel T-cell activation. In the setting of obesity, T cells have been found to have a key role in promoting the recruitment of inflammatory macrophages to adipose depots along with the production of inflammatory cytokines that promote the development of insulin resistance leading to diabetes. Deletion of T cells, key T-cell transcription factors, or pro-inflammatory T-cell cytokines prevents insulin resistance in obesity and underscores the importance of T cells in obesity-associated inflammation and metabolic disease. Altogether, T cells have a critical role in nutritional immunometabolism.
