Helicobacter 2025; 30:e70041. [PMID: 40338991 DOI: 10.1111/hel.70041] [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: 12/07/2024] [Revised: 04/17/2025] [Accepted: 04/23/2025] [Indexed: 05/10/2025]
Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection has the capacity to alter the gut microbiota composition. There is a significant correlation between H. pylori infection and type 2 diabetes mellitus (T2DM). Further research is necessary to explore whether gut microbiota plays a role in the relationship between H. pylori and T2DM. METHOD Fecal samples were obtained from 44 patients with T2DM, including 20 who tested positive for H. pylori and 24 who tested negative. Intestinal microbiota composition was analyzed via 16S rRNA V3-V4 amplicon sequencing. Differences in microbial distribution and significant microbial biomarkers were identified between H. pylori positive and negative groups. A Spearman correlation analysis assessed the relationship between intestinal microbiota and glycemic parameters. Additionally, PICRUSt2 was used to predict intestinal bacterial functions. RESULTS Results indicate that in H. pylori (+) T2DM patients, HbA1c levels were significantly higher (8.9% vs. 8.1%, p = 0.021), while both the C-peptide peak (3.70 vs. 5.98 ng/mL, p = 0.040) and fasting C-peptide levels (1.42 vs. 2.31 ng/mL, p = 0.008) were significantly lower compared to H. pylori (-) T2DM groups. A total of 11 colonic phyla and 100 genera were identified in all fecal samples. In groups positive for H. pylori, there was a significant enrichment of the phylum Proteobacteria, while the genera Lactobacillus, Butyricimonas, and Akkermansia were significantly reduced (all p < 0.05). Correlation analysis showed that the abundance of the genera Butyricimonas (p = 0.01) and Akkermansia (p = 0.048) were negatively correlated with fasting plasma glucose. KEGG pathway analysis indicated a significant enrichment of methylmalonyl-CoA mutase and succinyl-CoA in H. pylori-infected T2DM patients. CONCLUSIONS This study suggests that T2DM patients with H. pylori infection exhibit more impaired pancreatic islet function potentially due to H. pylori-induced alterations in the gut microbiota.

PLoS One 2025; 20:e0319688. [PMID: 40203057 PMCID: PMC11981135 DOI: 10.1371/journal.pone.0319688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2024] [Accepted: 02/05/2025] [Indexed: 04/11/2025] Open
Abstract
BACKGROUND Previous studies have shown that Helicobacter pylori infection is not only a risk factor for gastrointestinal diseases but also associated with various non-digestive conditions. This study aimed to investigate the effect of Helicobacter pylori infection on the risk of lipid metabolism disorders and cardiovascular disease in individuals with diabetes mellitus. METHODS This cross-sectional study was conducted at a health examination center. Data from life questionnaires, laboratory tests, the carbon-13 urea breath test, and the Framingham Risk Score were collected from 266 patients with diabetes. All participants were categorized into Helicobacter pylori-uninfected and Helicobacter pylori-infected groups based on the carbon-13 urea breath test results. Differences in lipid levels, Framingham Risk Score, and cardiovascular disease risk were compared between the two groups. A logistic regression model was applied to analyze whether Helicobacter pylori infection is an independent risk factor for dyslipidemia in patients with diabetes. RESULTS Total cholesterol and low-density lipoprotein cholesterol levels were higher in the Helicobacter pylori-infected group than in the uninfected group, and high-density lipoprotein cholesterol levels were lower in the infected group (both P < 0.05). There was no statistically significant difference in triglyceride levels between the two groups. Regression analysis showed that Helicobacter pylori infection was an independent risk factor for dyslipidemia in patients with diabetes (P < 0.05). The Framingham Risk Score and 10-year cardiovascular disease risk were higher in the Helicobacter pylori-infected group compared with the uninfected group (P < 0.001). CONCLUSION Helicobacter pylori infection is associated with dyslipidemia and may contribute to an increased risk of cardiovascular disease in individuals with diabetes.

Abstract
OBJECTIVE To determine the association of HP infection with COPD, assessing its prevalence and influence on symptoms, lung function, quality of life, exacerbations, hospitalizations, mortality, and healthcare costs. METHODS We performed a systematic review and meta-analysis after conducting a systematic literature search in PubMed, Embase, Cochrane Library, Virtual Health Library, ScienceDirect, Scopus, Researchgate, and GoogleScholar, from database inception to 31/12/2022. We used the Der Simonian-Laird method to calculate pooled HP prevalence, the Mantel-Haenszel model to determine the association of HP with COPD, and the inverse variance method to compare the pulmonary function tests between infected and uninfected patients, always with a fixed-effect model. RESULTS Twenty-eight studies included a total of 8647 patients with COPD. The pooled prevalence of HP infection was 29.8% (95%CI 29.0-30.7%). The more severe stage of COPD lesser the prevalence of HP (p < 0.001). HP infection was associated with COPD, estimated odds ratio 1.90 (95%CI 1.71, 2.12), p < 0.001. The mean differences for p%FEV1, p%FVC and FEV1/FVC ratio between HP infected and uninfected patients with COPD were -13.06 (95%CI -14.54, -11.58), -3.72 (95%CI -5.64, -1.79) and -0.01 (95%CI -0.02, -0.00) respectively. CONCLUSION Our meta-analysis suggests an appreciable relationship between HP infection and COPD. Further longitudinal studies considerating confounders and investigating causality are required.

Abstract
BACKGROUND While Helicobacter pylori (H. pylori) infection is associated with insulin resistance and higher mortality, research on insulin resistance indices and outcomes in H. pylori-infected patients is scarce. This study examines the association between the triglyceride-glucose (TyG) index, an insulin resistance marker, and all-cause and cardiovascular mortality in these patients. METHODS This study analyzed NHANES 1999-2000 data to assess the association between the TyG index and all-cause and cardiovascular mortality in H. pylori-infected patients using weighted Cox models and restricted cubic spline analysis. RESULTS Among 627 participants with a median follow-up of 20.8 years, 108 all-cause and 28 cardiovascular deaths occurred. Cox models showed that TyG was linked to a hazard ratio (HR) of 1.70 for all-cause mortality (95% CI: 1.23-2.34, P < 0.01) and an HR of 2.90 for cardiovascular mortality (95% CI: 1.91-4.42, P < 0.001). Restricted cubic spline analysis confirmed a linear relationship between the TyG index and both mortality risks. Stratified analyses showed that this relationship was significantly associated in most subgroups, but there was no significant interaction. CONCLUSION Higher TyG index is strongly linked to increased risks of both all-cause and cardiovascular mortality in H. pylori-infected patients.

Association between non-insulin-based insulin resistance surrogate makers and Helicobacter pylori infection: a population-based study. BMC Gastroenterol 2025; 25:25.

Abstract
BACKGROUND Current evidence on the associations between insulin resistance (IR) and Helicobacter pylori (H. pylori) infection remains limited. This study aimed to investigate the association between non-insulin-based surrogate markers of IR, including the triglyceride glucose (TyG) index, triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio, and the metabolic score for IR (METS-IR), and H. pylori infection in U.S. POPULATIONS METHODS This cross-sectional study involving 939 U.S. participants from the National Health and Nutrition Examination Survey (NHANES) 1999-2000. The associations between three IR surrogate markers and H. pylori infection were respectively investigated using logistic regression model, restricted cubic spline (RCS) curve and subgroup analysis. RESULTS Three IR surrogate markers levels were significantly elevated in H. pylori infection participants. There was a positive association between three IR surrogate markers and H. pylori infection, even after adjusting for potential confounding variables by three different models. In subgroup analysis, the adjusted association between three IR surrogate markers and H. pylori infection were more likely to be observed in female and Non-Hispanic White. Additionally, the RCS curve revealed a positive linear correlation between TyG index and H. pylori infection across all three models, and between METS-IR and H. pylori infection in Model 3. However, a positive nonlinear correlation was observed between TG/HDL-C ratio and H. pylori infection in all three models. CONCLUSIONS These findings suggest that non-insulin-based IR surrogate markers including TyG index, TG/HDL-C ratio, and METS-IR were all positively associated with H. pylori infection. These markers may serve as the potential indicators for identifying the risk of H. pylori infection in U.S. POPULATIONS CLINICAL TRIAL NUMBER Not applicable.

Abstract
Helicobacter pylori (H. pylori) infection is linked to metabolic syndrome and insulin resistance, with the triglyceride-glucose (TyG) index serving as a reliable marker for the latter. This study investigates the association between the TyG index and H. pylori infection. The study utilized cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2000. Participants underwent serologic testing for H. pylori, and the TyG index was calculated from fasting laboratory measurements. Multivariate logistic regression and restricted cubic spline methods were used to assess the association and explore the dose-response relationship. The analysis included 2984 participants. Elevated TyG index values were associated with an increased likelihood of H. pylori infection. The risk of infection rose with higher TyG index quartiles, with the highest quartile showing the most significant increase (OR = 1.54, 95% CI: 1.15-2.07, P = 0.004). A linear relationship between the TyG index and H. pylori infection was demonstrated. The study findings indicate a significant positive association between the TyG index and H. pylori infection. This association highlights the importance of metabolic health in the context of H. pylori infection and suggests that further research is needed to explore the potential implications for health promotion strategies.

Associations of Helicobacter pylori with metabolic dysfunction-associated steatotic liver disease and related conditions: cross-sectional results from the Hispanic Community Health Study/Study of Latinos. LANCET REGIONAL HEALTH. AMERICAS 2025; 41:100953. [PMID: 40321654 PMCID: PMC12049732 DOI: 10.1016/j.lana.2024.100953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2024] [Revised: 11/04/2024] [Accepted: 11/11/2024] [Indexed: 01/04/2025]
Abstract
Background Hispanic/Latino populations have been reported to have high rates of both metabolic dysfunction-associated steatotic liver disease (MASLD) and Helicobacter pylori infection. Several observational studies, predominantly from Asian populations, have suggested a link between these conditions. Thus, the primary objective of the current study was to examine the association between H. pylori and MASLD and secondarily, to assess its association with related conditions in the Hispanic Community Health Study/Study of Latinos. Methods In this cross-sectional study, a total of 16,144 participants with baseline data on H. pylori serology were included. Based on weighted statistics, the median age was 40 years [interquartile range (IQR): 28, 52]; 52.2% women (n = 9661) and 47.8% men (n = 6483). Participants' Hispanic/Latino heritage included 37.6% Mexicans (n = 6397), 20.1% Cubans (n = 2307), 15.8% Puerto Ricans (n = 2663), 10.0% Dominicans (n = 1447), 7.4% Central Americans (n = 1710), 4.9% South Americans (1052). MASLD was estimated using the Fatty Liver Index (FLI) and the Hepatic Steatosis Index (HSI). Other conditions examined were obesity, central obesity, diabetes and metabolic syndrome. Multivariable logistic regression models were used to calculate the ratios of (adjusted) prevalences (RP) and 95% confidence intervals (CI) for the overall association of H. pylori seropositivity with MASLD and related conditions. Analyses were also stratified by Hispanic/Latino heritage. Findings The overall prevalence of MASLD ranged from 47% (FLI) to 65% (HSI). After accounting for age, sex, education, and other key variables, the analysis found a modest association between H. pylori seropositivity and MASLD as determined by HSI (RP: 1.06, 95% CI: 1.02-1.10) overall, and among individuals of Puerto Rican and Mexican heritages. Furthermore, an overall association between H. pylori seropositivity and obesity was observed (RP: 1.09, 95% CI: 1.02-1.16). Interpretation This study provides support for a positive association of H. pylori seropositivity with MASLD and obesity among Hispanic/Latino populations. However, given the exploratory nature of these findings, caution is warranted in their interpretation. Further research is necessary to establish causality and examine potential mechanisms of these associations. Funding The Hispanic Community Health Study/Study of Latinos was carried out as a collaborative study supported by contracts from the National Heart, Lung, and Blood Institute (NHLBI) to the University of North Carolina (N01-HC65233), University of Miami (N01-HC65234), Albert Einstein College of Medicine (N01-HC65235), Northwestern University (N01-HC65236), San Diego State University (N01-HC65237), and University of Illinois at Chicago (HHSN268201300003I).

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.

Munteanu SN, Huțanu D, Filip AM, Cozac-Szőke AR, Mocan S, Negovan A. Type 2 Diabetes Mellitus and Helicobacter pylori Gastritis in Patients Referred for Endoscopy-A Single-Center Romanian Study. Life (Basel) 2024; 14:1160. [PMID: 39337943 PMCID: PMC11433160 DOI: 10.3390/life14091160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2024] [Revised: 09/10/2024] [Accepted: 09/12/2024] [Indexed: 09/30/2024] Open
Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) affects up to 10% of adults globally, and its complications can mask the risk of gastrointestinal bleeding or malignancy. METHODS Our study enrolled 633 endoscopic patients stratified according to T2DM presence (4:1 ratio in favor of the control group). RESULTS T2DM patients referred for endoscopy experienced lower prevalence of epigastric pain and heartburn (OR = 0.637/OR = 0.346, p < 0.05). Often being anemic (OR = 2.23, p < 0.001), they had significantly lower hemoglobin (p = 0.001) and serum iron (p = 0.02), but serum cholesterol was higher in non-diabetics. Ulcers, erosions and mucosal hemorrhages were comparable between groups (p < 0.05), although low-dose aspirin use was more prevalent in diabetics (p = 0.000, OR = 2.34). T2DM was associated with the increased frequency of antro-corporal active gastritis (OR = 1.451/OR 1.501), with smokers presenting a higher frequency of active H. pylori infection (OR = 3.37). T2DM predicted anemia (adjusted OR = 1.70) and the absence of gastroesophageal reflux symptoms (adjusted OR = 0.37), but not active H. pylori gastritis or premalignant lesions. CONCLUSION In an endoscopic population, patients with T2DM had lower hemoglobin and serum iron levels. There was an inverse correlation between T2DM and heartburn. H. pylori gastritis and premalignant lesions occurred more frequently in diabetic patients (predominantly pangastritis) before adjusting for age or associated comorbidities, with smoking increasing the risk for active infection.

Helicobacter pylori seropositivity associates with hyperglycemia, but not obesity, in Danish children and adolescents. BMC Med 2024; 22:379.

Abstract
BACKGROUND Helicobacter pylori colonizes the human stomach and may affect the inflammatory response, hormone production related to energy regulation, and gastrointestinal microbiota composition. Previous studies have explored a potential association between H. pylori infection and pediatric obesity with varying results. Considering the immunomodulatory effects of early-life infection with H. pylori that can confer beneficial effects, we hypothesized that we would find an inverse relationship between H. pylori seropositivity and obesity among Danish children and adolescents. METHODS We assessed H. pylori seroprevalence in 713 subjects from an obesity clinic cohort and 990 subjects from a population-based cohort, aged 6 to 19 years, and examined its association with obesity and other cardiometabolic risk factors. RESULTS No association was found between H. pylori and body mass index standard deviation score (BMI SDS). H. pylori seropositivity was, however, significantly associated with higher fasting plasma glucose levels and the prevalence of hyperglycemia. CONCLUSION While we did not find an association between H. pylori seropositivity and BMI SDS, we observed a significant association with higher fasting plasma glucose levels and increased prevalence of hyperglycemia, suggesting that H. pylori infection may contribute to impaired glucose regulation in Danish children and adolescents.

Abstract
BACKGROUND Diabetes mellitus (DM) and Helicobacter pylori infection (HPI) pose increasing public health challenges in aging societies, sharing common pathophysiological mechanisms, and linked to significant health risks. Our study examines their respective impacts on all-cause and cardiovascular mortalities in a comprehensive longitudinal population-based analysis. METHODS The study analyzed data from the National Health and Nutrition Examination Survey (NHANES) database conducted between 1999 and 2019, which included information on Diabetes mellitus status and Helicobacter pylori infection status. Mortality data were obtained from the same database mentioned above. RESULTS Among the 2719 participants, 1362 (50.1%) were free of both diabetes mellitus (DM) and Helicobacter pylori infection (HP) (DM -/HP -), 140 (5.1%) had DM alone (DM +/HP -), 1011 (37.2%) had HP alone (DM -/HP +), and 206 (7.6%) had both DM and HP (DM +/HP +). Compared to the DM -/HP - group, the DM +/HP - and DM + /HP + groups demonstrated increased all-cause mortality with adjusted hazard ratios (HRs) of 1.40 (95% [CI] 1.07-1.78) and 1.46 (95% CI 1.15-1.84), respectively. For diabetic mortality, DM +/HP- group and DM + /HP + group showed increased HR of 6.30 (95% CI 1.30-30.43) and 8.56 (95% CI 1.98-36.94), respectively. For cardiovascular mortality, the DM + /HP- group and DM + /HP + group exhibited increased HR of 1.75 (95% CI 1.14-2.69) and 1.98 (95% CI 1.40-2.79), respectively. The DM + /HP + cohort displayed the highest risk of overall mortality (p for trend = 0.003), diabetic mortality (p for trend < 0.0001), an6d cardiovascular mortality (p for trend < 0.0001). CONCLUSIONS The concurrent presence of DM and Helicobacter pylori infection significantly amplifies the risk of all-cause, cardiovascular, and diabetic mortality. Individuals with either condition may necessitate heightened management to prevent the onset of the other ailment and reduce mortality rates.

Abstract
BACKGROUND Previous studies examined the association of Helicobacter pylori infection (H. pylori) with complications of diabetes, but the results have been inconsistent. The aim of this study of patients with type-2 diabetes (T2D) was to determine the association of H. pylori infection with the major complications of diabetes. METHODS This single-center retrospective study examined patients with T2D who received H. pylori testing between January 2016 and December 2021. Logistic regression analyses were used to evaluate the association of H. pylori infection with four major complications of diabetes. RESULTS We examined 960 patients with T2D, and 481 of them (50.1%) were positive for H. pylori. H. pylori infection was significantly associated with diabetic nephropathy (odds ratio [OR] = 1.462; 95% confidence interval [CI]: 1.006,2.126; P = 0.046). In addition, the co-occurrence of H. pylori positivity with hypertension (OR = 4.451; 95% CI: 2.351,8.427; P < 0.001), with glycated hemoglobin A1c (HbA1c) of at least 8% (OR = 2.925; 95% CI: 1.544,5.541; P = 0.001), and with diabetes duration of at least 9 years (OR = 3.305; 95% CI:1.823,5.993; P < 0.001) further increased the risk of diabetic nephropathy. There was no evidence of an association of H. pylori infection with retinopathy, neuropathy, or peripheral vascular disease. CONCLUSIONS Our study of T2D patients indicated that those with H. pylori infections had an increased risk of nephropathy, and this risk was greater in patients who also had hypertension, an HbA1c level of 8% or more, and diabetes duration of 9 years or more.

Abstract
BACKGROUND Limited research has explored the potential association between the Triglyceride-Glucose (TyG) and mortality, especially in individuals with Helicobacter pylori (H. pylori) infection. This study seeks to investigate the correlation between the TyG index and H. pylori infection and investigate whether the associations between the TyG index exposure and all-cause mortality are mediated by H. pylori infection. METHODS The study utilized data from the National Health and Nutrition Examination Survey (NHANES) 1999-2018, incorporating a final sample size of 2,187 participants. Both univariable and multivariable-adjusted logistic regression analyses were employed to examine the relationship between H. pylori infection and relevant covariates. To assess the association between TyG index, and all-cause mortality in individuals with or without H. pylori infection, Cox regression analysis, and restricted regression cubic spline analysis were implemented. RESULTS A significant positive correlation was observed between the TyG index and an elevated risk of H. pylori infection [OR 1.157, 95% CI (1.383 ~ 1.664)]. This correlation persisted even after adjusting for confounding factors [OR 1.189, 95% CI (1.003, 1.411), P < 0.05]. Furthermore, in patients with positive H. pylori infection, a noteworthy nonlinear correlation between the TyG index and all-cause mortality was identified (P = 0.0361). With an increase in the TyG index, all-cause mortality exhibited a corresponding rise, particularly following adjustment for all potential confounding factors. Conversely, in patients with negative H. pylori infection, no significant association was observed between the TyG index and all-cause mortality after adjusting for potential confounding factors. CONCLUSION A higher TyG index was linked to increased H. pylori infection risks. Participants in the higher quantile group of the TyG index are positively associated with higher all-cause mortality compared to the higher quantile group of the TyG index in H. pylori-positive participants instead of H. pylori-negative participants.

Abstract
Cleistocalyx operculatus flower buds have been widely used in traditional medicine because of their rich content of bioactive constituents. In this study, we obtained seven solvent extracts from the flower buds and evaluated their total phenolic (TPC), flavonoid (TFC), tannin (TTC), triterpenoid saponin (TSC), and alkaloid (TAC) contents. We assessed antioxidant activities using the DPPH assay and also looked at antimicrobial and enzyme inhibitory effects. The water extract possessed the highest TPC (328.9 mg GAE/g extract), followed by ethanol, methanol, and hexane extracts (85.4-101.5 mg GAE/g extract). Chloroform, butanol, ethyl acetate, and ethanol extracts had high TSCs (245.4-287.2 mg OAE/g extract). The hexane extract was richest in TTC and TFC (32.7 mg CE/g extract and 81.1 mg QE/g extract, respectively). Ethanol and methanol extracts exhibited the strongest antioxidant activities (IC50 values of 25.2 and 30.3 μg/ml, respectively), followed by the water extract (IC50 of 40.2 μg/ml). The hexane extract displayed the most growth-inhibitory activity against Helicobacter pylori ATCC51932 and ATCC43504 strains and Salmonella enterica serovar Typhimurium ATCC13311 (MIC values of 0.06, 0.13, and 0.4 mg/ml, respectively). Moreover, the hexane extract revealed the strongest inhibition of H. pylori urease activity (IC50 of 4.51 μg/ml), whereas the water and methanol extracts had potent inhibitory effects on α-glucosidase activity (IC50 values of 9.9 and 15.1 μg/ml, respectively). These flower bud extracts could be used for health protection, especially in preventing bacterial infections and inhibiting enzymes associated with various human diseases. Further investigation into the application of C. operculatus flower buds in the food and pharmaceutical industries is necessary.

Abstract
Studies suggest links between diabetes and gastrointestinal (GI) traits; however, their underlying biological mechanisms remain unclear. Here, we comprehensively assess the genetic relationship between type 2 diabetes (T2D) and GI disorders. Our study demonstrates a significant positive global genetic correlation of T2D with peptic ulcer disease (PUD), irritable bowel syndrome (IBS), gastritis-duodenitis, gastroesophageal reflux disease (GERD), and diverticular disease, but not inflammatory bowel disease (IBD). We identify several positive local genetic correlations (negative for T2D - IBD) contributing to T2D's relationship with GI disorders. Univariable and multivariable Mendelian randomisation analyses suggest causal effects of T2D on PUD and gastritis-duodenitis and bidirectionally with GERD. Gene-based analyses reveal a gene-level genetic overlap between T2D and GI disorders and identify several shared genes reaching genome-wide significance. Pathway-based study implicates leptin (T2D - IBD), thyroid, interferon, and notch signalling (T2D - IBS), abnormal circulating calcium (T2D - PUD), cardiovascular, viral, proinflammatory and (auto)immune-mediated mechanisms in T2D and GI disorders. These findings support a risk-increasing genetic overlap between T2D and GI disorders (except IBD), implicate shared biological pathways with putative causality for certain T2D - GI pairs, and identify targets for further investigation.

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.

[PMID: 38256380 PMCID: PMC10821400 DOI: 10.3390/medicina60010119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 12/11/2023] [Accepted: 12/28/2023] [Indexed: 01/24/2024]
Abstract
Background and Objectives: Type 1 diabetes mellitus (T1DM) is a chronic and serious condition that is characterized by inadequate pancreatic-β-cells' insulin production. The connection between T1DM and Helicobacter pylori infection remains uncertain. This study aimed to conduct a systematic meta-analysis to examine the association between H. pylori infection, hemoglobin A1c levels, and the development of T1DM. Materials and Methods: The initial search identified 451 articles on the association between H. pylori infection and T1DM. Among them, 12 articles had 2797 participants who met the inclusion criteria for an advanced meta-analysis. Results: A significant association was observed between H. pylori infection and T1DM (OR 1.77, 95% CI 1.47-2.12, p < 0.0001), with heterogeneity: Tau2 = 0.47; Chi2 = 57.07, df = 11 (p < 0.0001); I2 = 81%. Subgroup analysis showed that H. pylori infection was significantly associated with a longer duration of T1DM and higher hemoglobin A1c levels (p < 0.001 for both) but not with age at T1DM diagnosis (p = 0.306). Conclusions: These findings contribute to the understanding of the association between H. pylori infection and T1DM and highlight the potential role of H. pylori in influencing the duration and glycemic control of diabetes. Therefore, pediatric patients who have longstanding T1DM and poor glycemic control should be screened for H. pylori infection.

Abstract
Diabetes mellitus with cardiovascular diseases is often a multi-systemic disease that requires a multi-therapeutic approach which mostly poses a challenge to laboratory result interpretation. The non-availability of information on many patients due to poor referral, documentation and record keeping has resulted in isolated interpretation of laboratory result of diabetic patients with multisystemic complications. This has led to both analytical and post-analytical errors which has a negative impact on total quality of results. Therefore, this review showed the possible therapeutic treatment of a diabetic patient with cardiovascular disease and how their pharmacological role could affect laboratory result.

Abstract
Atherosclerosis is a major instigator of cardiovascular disease (CVD) and a main cause of global morbidity and mortality. The high prevalence of CVD calls for urgent attention to possible preventive measures in order to curb its incidence. Traditional risk factors of atherosclerosis, like age, smoking, diabetes mellitus, dyslipidemia, hypertension and chronic inflammation, are under extensive investigation. However, these only account for around 50% of the etiology of atherosclerosis, mandating a search for different or overlooked risk factors. In this regard, chronic infections, by Helicobacter pylori for instance, are a primary candidate. H. pylori colonizes the gut and contributes to several gastrointestinal diseases, but, recently, the potential involvement of this bacterium in extra-gastric diseases including CVD has been under the spotlight. Indeed, H. pylori infection appears to stimulate foam cell formation as well as chronic immune responses that could upregulate key inflammatory mediators including cytokines, C-reactive protein, and lipoproteins. These factors are involved in the thickening of intima-media of carotid arteries (CIMT), a hallmark of atherosclerosis. Interestingly, H. pylori infection was found to increase (CIMT), which along with other evidence, could implicate H. pylori in the pathogenesis of atherosclerosis. Nevertheless, the involvement of H. pylori in CVD and atherosclerosis remains controversial as several studies report no connection between H. pylori and atherosclerosis. This review examines and critically discusses the evidence that argues for a potential role of this bacterium in atherogenesis. However, additional basic and clinical research studies are warranted to convincingly establish the association between H. pylori and atherosclerosis.

Abstract
Mesenchymal stromal cells, commonly referred to as MSCs, are a type of multipotent stem cells that are typically extracted from adipose tissue and bone marrow. In the field of tissue engineering and regenerative medicine, MSCs and their exosomes have emerged as revolutionary tools. Researchers are now devoting greater attention to MSCs because of their ability to generate skin cells like fibroblasts and keratinocytes, as well as their distinctive potential to decrease inflammation and emit pro-angiogenic molecules at the site of wounds. More recent investigations revealed that MSCs can exert numerous direct and indirect antimicrobial effects that are immunologically mediated. Collectively, these antimicrobial properties can remove bacterial infections when the MSCs are delivered in a therapeutic setting. Regardless of the positive therapeutic potential of MSCs for a multitude of conditions, transplanted MSC cell retention continues to be a major challenge. Since MSCs are typically administered into naturally hypoxic tissues, understanding the impact of hypoxia on the functioning of MSCs is crucial. Hypoxia has been postulated to be among the factors determining the differentiation of MSCs, resulting in the production of inflammatory cytokines throughout the process of tissue regeneration and wound repair. This has opened new horizons in developing MSC-based systems as a potent therapeutic tool in oxygen-deprived regions, including anaerobic wound infection sites. This review sheds light on the role of hypoxia-MSCs in the treatment of anaerobic bacterial wound infection in terms of both their regenerative and antimicrobial activities.

Abstract
INTRODUCTION Helicobacter pylori colonizes the human stomach. Infection causes chronic gastritis and increases the risk of gastroduodenal ulcer and gastric cancer. Its chronic colonization in the stomach triggers aberrant epithelial and inflammatory signals that are also associated with systemic alterations. METHODS Using a PheWAS analysis in more than 8,000 participants in the community-based UK Biobank, we explored the association of H. pylori positivity with gastric and extragastric disease and mortality in a European country. RESULTS Along with well-established gastric diseases, we dominantly found overrepresented cardiovascular, respiratory, and metabolic disorders. Using multivariate analysis, the overall mortality of H. pylori -positive participants was not altered, while the respiratory and Coronovirus 2019-associated mortality increased. Lipidomic analysis for H. pylori -positive participants revealed a dyslipidemic profile with reduced high-density lipoprotein cholesterol and omega-3 fatty acids, which may represent a causative link between infection, systemic inflammation, and disease. DISCUSSION Our study of H. pylori positivity demonstrates that it plays an organ- and disease entity-specific role in the development of human disease and highlights the importance of further research into the systemic effects of H. pylori infection.

Abstract
Background Globally, metabolic syndrome (MS) and Helicobacter pylori (HP) infection, which have gained an epidemic status, are major challenges to human health, society, and medical professionals. Recent studies have demonstrated that MS is closely related to HP infection. Additionally, HP is an important risk factor for gastric cancer. However, systematic reviews on HP are lacking. This review aimed to summarize and analyze the potential correlation of HP infection with MS and its components, as well as the underlying mechanism, to provide reference and strategies for clinical prevention and treatment. Methodology Previous studies examining the correlation between HP and MS since 1990 were retrieved from the PubMed, Web of Science, and Embase databases. The potential correlation between HP infection and MS and its components was comprehensively analyzed. The keywords "Helicobacter pylori," "HP," "metabolic syndrome," "hypertension," "obesity," "diabetes," or "dyslipidemia" were used in all fields. No language restrictions were imposed. Results MS was strongly correlated to HP infection. The inflammatory response and inflammatory factors produced during HP infection are important etiological factors for insulin resistance and MS. The co-occurrence of long-term chronic inflammation and immune dysfunction with MS may be the predisposing factor for HP infection. MS components, such as diabetes, hypertension, dyslipidemia, and obesity were also correlated with HP infection in one or both directions. Conclusions HP infection and MS may promote the pathogenesis of each other. The contribution of HP infection and MS to gastric cancer cannot be ruled out based on co-occurrence. The MS components diabetes and obesity may be bidirectionally correlated with HP infection.

Abstract
BACKGROUND Helicobacter pylori infection and irritable bowel syndrome (IBS) negatively affect the quality of life. Some previous studies found that H. pylori infection should be positively associated with the risk of IBS, but others did not. The present study aims to clarify this association, and to further analyse whether H. pylori treatment can improve IBS symptoms. MATERIALS AND METHODS The PubMed, EMBASE, Cochrane library, Chinese National Knowledge Infrastructure, China Science and Technology Journal and Wanfang databases were searched. Meta-analysis was performed using a random-effect model. The pooled odds ratios (ORs)/risk ratios (RRs) and their 95% CIs were calculated. Heterogeneity was evaluated using the Cochran's Q test and I2 statistics. Meta-regression analysis was used to explore the sources of heterogeneity. RESULTS Thirty-one studies with 21 867 individuals were included. Meta-analysis of 27 studies found that patients with IBS had a significantly higher risk of H. pylori infection than those without (OR = 1.68, 95% CI 1.29 to 2.18; p < 0.001). The heterogeneity was statistically significant (I² = 85%; p < 0.001). Meta-regression analyses indicated that study design and diagnostic criteria of IBS might be the potential sources of heterogeneity. Meta-analysis of eight studies demonstrated that H. pylori eradication treatment had a higher improvement rate of IBS symptoms (RR = 1.24, 95% CI 1.10 to 1.39; p < 0.001). The heterogeneity was not significant (I² = 32%; p = 0.170). Meta-analysis of four studies also demonstrated that successful H. pylori eradication had a higher improvement rate of IBS symptoms (RR = 1.25, 95% CI 1.01 to 1.53; p = 0.040). The heterogeneity was not significant (I² = 1%; p = 0.390). CONCLUSION H. pylori infection is associated with an increased risk of IBS. H. pylori eradication treatment can improve IBS symptoms.

Abstract
BACKGROUND It has been assumed that perinatal factors such as multiple pregnancies may affect subsequent breast cancer risk in the mother. Considering the inconsistencies in the results of case-control and cohort studies published in the world, this meta-analysis was conducted in order to determine the exact association between multiple pregnancies (twins or more) and the breast cancer incidence. METHODS This study was performed as a meta-analysis based on PRISMA guidelines by searching the international databases of PubMed (Medline), Scopus, and Web of Science as well as by screening selected articles based on their subject, abstract and full text. The search time was from January 1983 to November 2022. Then the NOS checklist was used to evaluate the quality of the final selected articles. The indicators considered for the meta-analysis included the odds ratio (OR) and the risk ratio (RR) along with the confidence interval reported in the selected primary studies. The desired analyzes were performed with STATA software version 17 to be reported. RESULTS In this meta-analysis, 19 studies were finally selected for analysis, which fully met the inclusion criteria. Of these, 11 were case-control studies and 8 were cohort ones. Their sample size was 263,956 women (48,696 with breast cancer and 215,260 healthy) and 1,658,378 (63,328 twin or multiple pregnancies and 1,595,050 singleton pregnancies), respectively. After combining the results of cohort and case-control studies, the effect of multiple pregnancies on the breast cancer incidence was equal to 1.01 (95% CI: 0.89-1.14; I2: 44.88%, P: 0.06) and 0.89 (95% CI: 0.83-0.95; I2: 41.73%, P: 0.07), respectively. CONCLUSION The present meta-analysis results showed, in general, multiple pregnancies were one of the preventive factors of breast cancer.

Abstract
BACKGROUND Helicobacter pylori (Hp) is among the most common bacterial infections in the world and one of the most common infectious agents linked to malignancy, gastric cancer (GC). Within the US there is high disparity in the rates of Hp infection and associated diseases. Hp infection is treatable, and knowledge may influence screening and treatment seeking behaviors. MATERIALS AND METHODS In this cross-sectional study of 1042 respondents recruited from the Online Amazon MTurk platform, we sought to assess baseline knowledge of Hp and to gain insight into barriers related to Hp care. RESULTS Just over half (52.3%) reported some prior knowledge of Hp with 11.7% (n = 122) reporting being treated for Hp themselves and 21.4% reporting family members diagnosed with Hp. Of respondents reporting prior treatment, 95 (78%) reported GI upset and 27 (21%) reported not completing medications. Specific to Hp and GC, 70% indicated that a belief that the treatment was worse than the symptoms would affect their willingness to seek care, while 81% indicated knowing Hp can cause GC would affect their treatment decisions and knowing their gastric symptoms were caused by Hp would affect their willingness to receive care. CONCLUSIONS Knowledge of Hp in this US sample of online respondents is low and self-reported difficulties with treatment compliance is high. Increasing awareness of this infection and addressing the challenges to treatment compliance could potentially reduce rates of Hp antibiotic resistance and progression to GC or other complications of Hp infection.

Abstract
Purpose Type 1 diabetes mellitus (T1DM) is associated with different types of infections; however, studies on the causal relationship between T1DM and infectious diseases are lacking. Therefore, our study aimed to explore the causalities between T1DM and six high-frequency infections using a Mendelian randomization (MR) approach. Methods Two-sample MR studies were conducted to explore the causalities between T1DM and six high-frequency infections: sepsis, acute lower respiratory infections (ALRIs), intestinal infections (IIs), infections of the genitourinary tract (GUTIs) in pregnancy, infections of the skin and subcutaneous tissues (SSTIs), and urinary tract infections (UTIs). Data on summary statistics for T1DM and infections were obtained from the European Bioinformatics Institute database, the United Kingdom Biobank, FinnGen biobank, and Medical Research Council Integrative Epidemiology Unit. All data obtained for summary statistics were from European countries. The inverse-variance weighted (IVW) method was employed as the main analysis. Considering the multiple comparisons, statistical significance was set at p< 0.008. If univariate MR analyses found a significant causal association, multivariable MR (MVMR) analyses were performed to adjust body mass index (BMI) and glycated hemoglobin (HbA1c). MVMR-IVW was performed as the primary analysis, and the least absolute shrinkage and selection operator (LASSO) regression and MVMR-Robust were performed as complementary analyses. Results MR analysis showed that susceptibility to IIs increased in patients with T1DM by 6.09% using the IVW-fixed method [odds ratio (OR)=1.0609; 95% confidence interval (CI): 1.0281-1.0947, p=0.0002]. Results were still significant after multiple testing. Sensitivity analyses did not show any significant horizontal pleiotropy or heterogeneity. After adjusting for BMI and HbA1c, MVMR-IVW (OR=1.0942; 95% CI: 1.0666-1.1224, p<0.0001) showed significant outcomes that were consistent with those of LASSO regression and MVMR-Robust. However, no significant causal relationship was found between T1DM and sepsis susceptibility, ALRI susceptibility, GUTI susceptibility in pregnancy, SSTI susceptibility, and UTI susceptibility. Conclusions Our MR analysis genetically predicted increased susceptibility to IIs in T1DM. However, no causality between T1DM and sepsis, ALRIs, GUTIs in pregnancy, SSTIs, or UTIs was found. Larger epidemiological and metagenomic studies are required to further investigate the observed associations between the susceptibility of certain infectious diseases with T1DM.

Abstract
The gut microbiota represents a diverse and dynamic population of microorganisms that can influence the health of the host. Increasing evidence supports the role of the gut microbiota as a key player in the pathogenesis of neurodegenerative diseases, including Alzheimer's disease (AD). Unfortunately, the mechanisms behind the interplay between gut pathogens and AD are still elusive. It is known that bacteria-derived outer membrane vesicles (OMVs) act as natural carriers of virulence factors that are central players in the pathogenesis of the bacteria. Helicobacter pylori (H. pylori) is a common gastric pathogen and H. pylori infection has been associated with an increased risk to develop AD. Here, we are the first to shed light on the role of OMVs derived from H. pylori on the brain in healthy conditions and on disease pathology in the case of AD. Our results reveal that H. pylori OMVs can cross the biological barriers, eventually reaching the brain. Once in the brain, these OMVs are taken up by astrocytes, which induce activation of glial cells and neuronal dysfunction, ultimately leading to exacerbated amyloid-β pathology and cognitive decline. Mechanistically, we identified a critical role for the complement component 3 (C3)-C3a receptor (C3aR) signalling in mediating the interaction between astrocytes, microglia and neurons upon the presence of gut H. pylori OMVs. Taken together, our study reveals that H. pylori has a detrimental effect on brain functionality and accelerates AD development via OMVs and C3-C3aR signalling.

Abstract
BACKGROUND The association between Helicobacter pylori (Hp) infection and non-alcoholic fatty liver disease (NAFLD) is subject of a contentious debate. Data mainly stem from Asian cohorts whereas European data are scarce. We, therefore, investigated an Austrian colorectal cancer screening cohort for an association between Hp and NAFLD. METHODS In total, 5338 consecutive participants undergoing screening colonoscopy at a single center in Austria were evaluated in this cross-sectional study. The primary risk factor was being Hp negative or positive. The primary endpoint was the presence of NAFLD defined by ultrasound (NAFLD; primary endpoint). Uni- and multivariable logistic regression models were fitted to obtain odds ratios (OR) and 95% confidence intervals (95%CI). Finally, this association was analyzed in a subgroup of 1128 patients in whom NAFLD was diagnosed by transient elastography (TE, secondary endpoint). RESULTS NAFLD prevalence defined by ultrasound did not differ between Hp positive (48%) and negative patients (45%, P=0.097). Accordingly, in uni- (OR 1.12 95% CI 0.98-1.29; P=0.098) and multivariable analysis adjusting for different risk factors (aOR 0.96 95%CI 0.82-1.13; P=0.601) no independent association was found. On subgroup analysis, NAFLD diagnosed by TE was more prevalent in the Hp positive compared to the Hp negative group (49% vs. 38%, P=0.004) and these patients also had higher steatosis grades. However, after adjustment for risk factors, no independent association between Hp positivity and NAFLD diagnosed by TE (aOR 1.26 95%CI 0.89-1.78; P=0.194) was confirmed. CONCLUSIONS In this Central European cohort, Hp-positivity was not associated with the diagnosis of NAFLD. Although Hp positive patients seem to be more likely to have a concomitant NAFLD diagnosis, this association might rather relate to a cardiometabolic risk phenotype than causality.

Abstract
Helicobacter pylori (H. pylori) infection occurs in almost half of the world's population, most of whom are merely carriers of this microorganism. H. pylori is shown to be detected more frequently in patients with diabetes mellitus (DM) than in the general population, which is accompanied by a significantly increased risk of developing H. pylori-associated diseases. In addition, eradication therapy shows a low efficiency for H. pylori infection in patients with DM. There is a relationship between the level of chronic hyperglycemia and a higher detection rate of H. pylori as well as a lower efficiency of eradication therapy in patients with DM. The exact mechanisms of these phenomena are unknown. The authors make a hypothesis that explains the relationship between chronic hyperglycemia and the increased detection rate of H. pylori, as well as the mechanisms contributing to the improved survival of this bacterium in patients with DM during eradication therapy.

Abstract
The number of diabetes mellitus patients has increased over the last few years in developing countries, along with obesity and sedentary lifestyle. Besides macroangiopathy and microangiopathy, damage to the nerve fibers of the peripheral nervous system is the most common chronic complication of diabetes. Digestive complications in diabetic patients represent a consequence of diabetic autonomic neuropathy involving the gastrointestinal tract, but unfortunately not always evaluated by diabetologists. Aside from the complications encountered in the digestive tract, patients with diabetes mellitus are prone to developing liver diseases. This review will describe the prevalence of these complications, the modality of diagnosis, and therapeutical solutions in order to reduce the risk of progression of these complications in diabetic subjects.

Abstract
Considered as the most popular pathogen worldwide, Helicobacter pylori is intensively associated with diverse gastric diseases, including gastric ulcers, chronic progressive gastritis, and gastric cancer. Aside from its pathogenic effect on gastric diseases, growing evidences reveal that H. pylori may be related to numerous extragastric diseases. In this article, we reviewed recent studies and systematically elucidated that H. pylori may interfere with many biological processes outside the stomach and influence the occurrence of various extragastric diseases. Many epidemiological studies have indicated that H. pylori plays a pathogenic role in COVID-19, atherosclerosis, hyperemesis gravidarum and several other extragastric diseases, while the effect of H. pylori is currently under investigation in gastroesophageal reflux disease, asthma, and inflammatory bowel disease. Moreover, we also summarized the possible pathogenic mechanisms of H. pylori that may be related to chronic systemic inflammation and molecular mimicker. Taken together, this review provides a new perspective on the role of H. pylori in extragastric diseases and explores the possible mechanisms, which may help guide clinical treatment.

Abstract
Evidence about the relationship between Helicobacter pylori (Hp) infection and type 2 diabetes mellitus (T2DM) is inconsistent and contradictory. This study attempted to investigate this association in the middle-aged and elderly Chinese population and analyze the joint effects of Hp infection and some risk factors on T2DM. Following a cross-sectional design, participants were recruited from the First Affiliated Hospital of Anhui Medical University in Hefei City, China. Hp status was measured using a 14C urea breath test. A total of 1,288 participants, including 90 diabetic patients and 1,198 nondiabetic subjects, were recruited in the current study. The participants with T2DM had a greater prevalence of Hp infection than participants without T2DM (26.67% versus 18.11%, p = 0.045). Furthermore, we found that Hp infection was closely associated with an incremental risk of T2DM [odds ratio (OR) = 1.77, 95% confidence intervals (CI): 1.04-3.00] after adjustment for potential confounders. In addition, we observed that the participants who were Hp-positive and ≥60 years old (OR = 9.16, 95% CI: 3.29-25.52), Hp-positive and obese (OR = 3.35, 95% CI: 1.57-7.14) or Hp-positive and hypertensive (OR = 6.10, 95% CI: 3.10-12.01) had a significantly higher risk for T2DM than those who were Hp-negative and ≤50 years old, Hp-negative and nonobese or Hp-negative and nonhypertensive. These findings imply that Hp infection is associated with an increased risk of T2DM in the middle-aged and elderly Chinese population. The association could be further elevated by the combination of Hp infection and some traditional risk factors.

Abstract
Helicobacter pylori(H. pylori) which are known as Gram-negative bacteria tend to selectively colonize in the gastric epithelium. The infiltration of neutrophilic and mononuclear cells in the antrum and corpus mucosa is one of the consequences of acute and chronic gastritis colonization with H. pylori. This chronic active gastritis is the primary condition related to H. pylori colonization, and other H. pylori-associated disorders result from this chronic inflammatory process. The present study aimed to assess the relationship between H. pylori infection and extra-gastroduodenal manifestations, such as iron deficiency anemia, chronic spontaneous urticarial, diabetes mellitus, and celiac diseases with low ferritin levels. There were 235 subjects aged 3-75 years in the patient's group. The selected eligible patients were subjected to examination by non-invasive methods using stool antigen test and 14C-urea breath test (14C-UBT). The H. pylori antigen rapid test cassette (feces) was used for the qualitative detection of H. pylori antigens in human feces specimens. In the present study, 183 (71.8%) patients demonstrated positive results for H. pylori which had been detected by stool antigen test, out of whom 106 (57.9%) and 77 (42.1%) cases were female and male, respectively. The recorded data pointed out that the rates of Iron deficiency anemia, diabetes mellitus, and celiac diseases were 92(50.3%), 62 (33.9%), and 25 (13.7%), respectively. The findings of the present study revealed that H. pylori is more prevalent in females. Moreover, the diagnostic potential of the 14C UBT method was higher and more accurate than the stool antigen assay.

Abstract
BACKGROUND Conflicting results of recent studies on the association between Helicobacter pylori (H. pylori) infection and the risk of insulin resistance and metabolic syndrome explored the need for updated meta-analysis on this issue. Therefore, this systematic review aimed to estimate the pooled effect of H. pylori infection on the risk of insulin resistance and metabolic syndrome. METHODS To identify case-control studies and cohort studies evaluating the association of H. pylori infection with insulin resistance and metabolic syndrome, a comprehensive literature search was performed from international databases including Medline (PubMed), Web of Sciences, Scopus, EMBASE, and CINHAL from January 1990 until January 2021. We used odds ratio with its 95% confidence interval to quantify the effect of case-control studies and risk ratio with its 95% CI for the effect of cohort studies. RESULTS 22 studies with 206,911 participants were included for meta-analysis. The pooled estimate of odds ratio between H. pylori infection and metabolic syndrome in case-control studies was 1.19 (95% CI 1.05-1.35; I2 = 0%), and in cohort studies, the pooled risk ratio was 1.31 (95% CI 1.13-1.51; I2 = 0%). Besides, case-control studies showed the pooled odds ratio of 1.54 (95% CI 1.19-1.98; I2 = 6.88%) for the association between H. pylori infection and insulin resistance. CONCLUSION In this meta-analysis, the results showed that there was a possibility of metabolic syndrome and insulin resistance in case of H. pylori infection.

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
Diabetes is one of the four major non-communicable diseases, and appointed by the world health organization as the seventh leading cause of death worldwide. The scientists have turned over every rock in the corners of medical sciences in order to come up with better understanding and hence more effective treatments of diabetes. The continuous research on the subject has elucidated the role of immune disorders and inflammation as definitive factors in the trajectory of diabetes, assuring that blood glucose adjustments would result in a relief in the systemic stress leading to minimizing inflammation. On a parallel basis, microbial infections usually take advantage of immunity disorders and propagate creating a pro-inflammatory environment, all of which can be reversed by antimicrobial treatment. Standing at the crossroads between diabetes, immunity and infection, we aim in this review at projecting the interplay between immunity and diabetes, shedding the light on the overlapping playgrounds for the activity of some antimicrobial and anti-diabetic agents. Furthermore, we focused on the anti-diabetic drugs that can confer antimicrobial or anti-virulence activities.

Abstract
Helicobacter pylori (H. pylori) is a 0.5-1 µm wide, 2-4 µm long, short helical, S-shaped Gram-negative microorganism. It is mostly found in the pyloric region of the stomach and causes chronic gastric infection. It is estimated that these bacteria infect more than half of the world's population. The mode of transmission and infection of H. pylori is still not known exactly, but the faecal-oral and oral-oral routes via water or food consumption are thought to be a very common cause. In the last three decades, research interest has increased regarding the pathogenicity, microbial activity, genetic predisposition, and clinical treatments to understand the severity of gastric atrophy and gastric cancer caused by H. pylori. Studies have suggested a relationship between H. pylori infection and malabsorption of essential micronutrients, and noted that H. pylori infection may affect the prevalence of malnutrition in some risk groups. On the other hand, dietary factors may play a considerably important role in H. pylori infection, and it has been reported that an adequate and balanced diet, especially high fruit and vegetable consumption and low processed salty food consumption, has a protective effect against the outcomes of H. pylori infection. The present review provides an overview of all aspects of H. pylori infection, such as clinical features, treatment, and nutrition.

Abe Y, Kusano C, Takano C, Morioka I, Gotoda T. Association between Helicobacter pylori antibody-positive status and extragastric diseases in Japanese junior high school students. Pediatr Int 2021; 63:1087-1094. [PMID: 33351269 DOI: 10.1111/ped.14585] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 12/01/2020] [Accepted: 12/08/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection causes various extragastric diseases. Its transmission route has still not been clarified. However, no large-scale studies have examined the extragastric diseases caused by H. pylori in adolescents. This study aimed to examine the association of H. pylori infection with anemia, serum cholesterol levels, physique, and birth delivery method (vaginal or cesarean) in a large number of Japanese adolescents. METHODS From 2016 to 2018, we screened 2,399 adolescents (aged 13-15 years) in their second and third years of junior high school using an enzyme-linked immunosorbent assay-based antibody test. Red blood cells, hemoglobin, hematocrit, total cholesterol, high-density lipoprotein (HDL) cholesterol, and serum antibody levels were measured. RESULTS Hemoglobin and hematocrit levels were significantly lower in the H. pylori antibody-positive group than in the H. pylori antibody-negative group in both sexes (boys: P = 0.0004 and 0.0022; girls: P = 0.0019 and 0.0005, respectively). Total cholesterol and non-HDL cholesterol levels were significantly higher in the H. pylori-positive group than in the H. pylori-negative group among boys (P = 0.0370 and 0.0293 respectively). There was no significant difference in body mass index percentile and birth delivery method between the H. pylori-positive and H. pylori-negative groups in both boys and girls. CONCLUSIONS Among Japanese junior high school students, H. pylori antibody-positive status was associated with anemia in both sexes while total cholesterol and non-HDL cholesterol levels were associated among boys. There was no association between H. pylori antibody status, body mass index percentile, and birth-delivery method.

Proteomics Analysis of Gastric Cancer Patients with Diabetes Mellitus. J Clin Med 2021; 10:jcm10030407.

Abstract
Proteomics is a powerful approach to study the molecular mechanisms of cancer. In this study, we aim to characterize the proteomic profile of gastric cancer (GC) in patients with diabetes mellitus (DM) type 2. Forty GC tissue samples including 19 cases from diabetic patients and 21 cases from individuals without diabetes (control group) were selected for the proteomics analysis. Gastric tissues were processed following the single-pot, solid-phase-enhanced sample preparation approach-SP3 and enzymatic digestion with trypsin. The resulting peptides were analyzed by LC-MS Liquid Chromatography-Mass Spectrometry (LC-MS). The comparison of protein expression levels between GC samples from diabetic and non-diabetic patients was performed by label-free quantification (LFQ). A total of 6599 protein groups were identified in the 40 samples. Thirty-seven proteins were differentially expressed among the two groups, with 16 upregulated and 21 downregulated in the diabetic cohort. Statistical overrepresentation tests were considered for different annotation sets including the Gene Ontology(GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), Reactome, and Disease functional databases. Upregulated proteins in the GC samples from diabetic patients were particularly enriched in respiratory electron transport and alcohol metabolic biological processes, while downregulated proteins were associated with epithelial cancers, intestinal diseases, and cell-cell junction cellular components. Taken together, these results support the data already obtained by previous studies that associate diabetes with metabolic disorders and diabetes-associated diseases, such as Alzheimer's and Parkinson's, and also provide valuable insights into seven GC-associated protein targets, claudin-3, polymeric immunoglobulin receptor protein, cadherin-17, villin-1, transglutaminase-2, desmoglein-2, and mucin-13, which warrant further investigation.

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.

Seroprevalence of Helicobacter pylori and its association with metabolic syndrome in a rural community of Bangladesh. JGH Open 2021; 5:64-72. [PMID: 33490615 PMCID: PMC7812465 DOI: 10.1002/jgh3.12448] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 10/23/2020] [Accepted: 10/27/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND AND AIM As the interrelationship between Helicobacter pylori, metabolic syndrome (MetS), and non-alcoholic fatty liver disease (NAFLD) is controversial, we undertook a community-based study with the aim to find the seroprevalence of H. pylori and its relationship with MetS and NAFLD. METHODS This door-to-door survey was conducted among the adult subjects (≥18 years) of two villages (Charcharia of Dhaka district and Kharrah of Munshiganj district) of Bangladesh. Interviews using a structured questionnaire, clinical examination, anthropometric measurements, ultrasonogram of the liver, and biochemical tests were performed. RESULTS Of 1021 subjects, 781 responded (76.49%), and 767 were included in the final analysis (mean age 40.35 ± 15.56 years; female 63.5%). Anti-H. pylori antibodies were found in 418 of 767 (54.5%). There were no H. pylori serostatus association with MetS and diabetes mellitus (DM) in univariate or multivariate analysis (all P > 0.05). However, H. pylori seropositive subjects had lower systolic blood pressure (odds ratio [OR] = -2.95 [-5.58, -0.32]) and low density lipoprotein -cholesterol (OR -7.79 [-15, -0.57]) compared to seronegative subjects in the linear regression model. Seronegativity of H. pylori was associated with NALFD in univariate (P = 0.007) but not multivariate analysis (P = 0.086). There were no differences in the frequency of H. pylori seropositivity among the participants with nonobese compared to obese NAFLD (19/42 [45%] vs 43/99 [43.4%], P = 0.844). CONCLUSION In a rural community of Bangladesh, about 55% of the population were H. pylori seropositive, which was more common among the underweight than normal or obese subjects. However, there was no relationship observed between H. pylori seroprevalence and MetS, DM, or NAFLD.

Abstract
The involvement of Helicobacter pylori infection in many extra-gastroduodenal manifestations remains a fascinating field of investigation. However, for several of these supposed associations, the potential pathogenic mechanism remains unclear. The present review highlights the main associations of H pylori with extra-gastroduodenal manifestations reported during the last year. We searched for the most relevant studies on this topic, published between April 2019 and March 2020, identified using the term "Helicobacter" in the MEDLINE/Pubmed database. Consistent data emerged from studies investigating metabolic syndrome and ischaemic cardiovascular diseases. Other reported fields of investigation were hepatology, especially focused on non-alcoholic steatohepatitis, neurology, including Parkinson's disease and Alzheimer's disease, as well as dermatology. Inflammatory bowel disease (IBD), that comprises Crohn's disease and ulcerative colitis, may originate from a dysregulation of the host's immune response to commensal bacteria in individuals with genetic predisposition. The reduction of biodiversity and other specific imbalances in the faecal microbiome composition of IBD patients compared to that of healthy controls support this hypothesis. In this context, an inverse correlation between H pylori infection and IBD prevalence has been confirmed. Similar results were found in patients with kidney diseases and allergic manifestations. There are indications of the possible involvement of H pylori infection in metabolic syndrome and ischaemic cardiovascular diseases. However, due to a series of factors linked to study designs and the multifactorial pathogenesis of some diseases, further studies are needed.

Abstract
BACKGROUND Studies suggest an association between H. pylori infection and extragastrointestinal disease. Limited studies provided conflicting results on the association between H. pylori infection and diabetes. The present study was aimed at examining the association between H. pylori infection and diabetes in a large health checkup population in China. METHODS A cross-sectional study was conducted; participants who attended health checkups at Beijing MJ Health Screening Center during 2017-2018 were included. H. pylori infection was diagnosed by 13C-urea breath test. Multivariate logistic regression analysis was performed to evaluate the association between H. pylori infection and diabetes. RESULTS The mean age of 13,397 participants was 43.8 ± 12 years. The prevalence of H. pylori infection and diabetes was 28.2% and 8.1%, respectively. The prevalence of diabetes was higher among H. pylori-positive participants compared with their counterparts (8.9% vs 7.8%, p = 0.05). After adjustment of age, sex, family history of diabetes, smoking, education, stroke, coronary heart disease, BMI, SBP, TG, HDL-C, and LDL-C, multivariate logistic regression analysis found no association between H. pylori infection and diabetes (OR 1.02, 95% CI 0.88-1.18). Additionally, subgroup analysis indicated that H. pylori infection was significantly associated with increased risk of diabetes in the female group (OR 1.09, 95% CI 1.08-1.09). CONCLUSIONS No significant association was found between H. pylori infection and diabetes. However, the subgroup analysis suggested that H. pylori infection was possibly associated with increased risk of diabetes among females. Future cohort studies are needed to verify this association in females and to address possible implication in the prevention of diabetes.
