[PMID: 39215298 PMCID: PMC11363574 DOI: 10.1186/s12902-024-01694-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Accepted: 08/19/2024] [Indexed: 09/04/2024] Open
Abstract
PURPOSE This study aimed to preliminarily investigate the association and possible mechanisms between Helicobacter. pylori (H. pylori) infection and type 2 diabetes mellitus (T2DM) through data collection, statistical analysis, and bioinformatics analysis. METHODS A retrospective cohort study, including a total of 4406 participants who attended annual health checkups at Xian GEM Flower Changqing Hospital, was conducted to explore the correlation between the incidence of T2DM and H. pylori infection. To uncover the potential mechanisms underlying the interaction between the two diseases, differentially expressed genes (DEGs) common to T2DM and H. pylori infection were identified using the GEO database and Venn diagrams. These DEGs were then analyzed through Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment, and protein-protein interaction (PPI) analysis. RESULTS In total, 2053 participants were classified into the H. pylori-positive group and 2353 into the H. pylori-negative group. H. pylori infection was associated with a higher risk of T2DM occurrence (adjusted HR 1.59; 95% CI 1.17-2.15, P = 0.003). The average disease-free survival time was 34.81 months (95% CI 34.60-35.03 months) in the H. pylori positive group and 35.42 months (95% CI 35.28-35.56 months) in the H. pylori negative group. Multivariate analysis and subgroup analyses also showed that H. pylori infection increased the risk of developing T2DM. A total of 21 DEGs between T2DM and H. pylori infection were identified and enriched in 7 signaling pathways, indicating specific protein interactions. CONCLUSIONS The prevalence of T2DM was associated with H. pylori infection. T2DM and H. pylori infection may interact with each other through metabolic and immune pathways.

Abstract
PURPOSE OF REVIEW This review aims to analyse the consistency of reports suggesting the role of Diabetes Mellitus in the pathogenesis of Helicobacter pylori (H. pylori). RECENT FINDINGS There have been numerous controversies citing the prevalence of H. pylori infections in patients suffering from type 2 diabetes mellitus (T2DM). This review investigates the possible crosstalk between H. pylori infections and T2DM and also designs a meta-analysis to quantify the association. Subgroup analyses have also been conducted to deduce factors like geography and testing techniques, in playing a role in stratification analysis. Based on a scientific literature survey and meta-analysis of databases from 1996 to 2022, a trend towards more frequent H. pylori infections in patients with diabetes mellitus was observed. The highly diversified nature of H. pylori infections across age, gender, and geographical regions requires large interventional studies to evaluate its long-term association with diabetes mellitus. Further possible linkage of the prevalence of diabetes mellitus concomitant with that of H. pylori infected patients has also been delineated in the review.

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
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
Nearly half of all adults with type 2 diabetes mellitus (T2DM) live in India and China. These populations have an underlying predisposition to deficient insulin secretion, which has a key role in the pathogenesis of T2DM. Indian and Chinese people might be more susceptible to hepatic or skeletal muscle insulin resistance, respectively, than other populations, resulting in specific forms of insulin deficiency. Cluster-based phenotypic analyses demonstrate a higher frequency of severe insulin-deficient diabetes mellitus and younger ages at diagnosis, lower β-cell function, lower insulin resistance and lower BMI among Indian and Chinese people compared with European people. Individuals diagnosed earliest in life have the most aggressive course of disease and the highest risk of complications. These characteristics might contribute to distinctive responses to glucose-lowering medications. Incretin-based agents are particularly effective for lowering glucose levels in these populations; they enhance incretin-augmented insulin secretion and suppress glucagon secretion. Sodium-glucose cotransporter 2 inhibitors might also lower blood levels of glucose especially effectively among Asian people, while α-glucosidase inhibitors are better tolerated in east Asian populations versus other populations. Further research is needed to better characterize and address the pathophysiology and phenotypes of T2DM in Indian and Chinese populations, and to further develop individualized treatment strategies.

Abstract
This study examined differences in glycated hemoglobin (HbA1c), fasting plasma glucose and cholesterol levels between H. pylori infected and uninfected persons with diabetes. Anonymized data of Maccabi Healthcare Services in Israel were analyzed, of 12,207 individuals (50.0% H. pylori positive) aged 25–95 years who underwent the urea breath test. The data included HbA1c, fasting plasma glucose and cholesterol levels. The inverse probability of treatment weighting approach was used to account for confounders. Differences between individuals who were H. pylori positive and negative, in HbA1c (> or ≤ 7.0%) and in cholesterol levels were assessed using weighted generalized estimating equations. For men, but not women, the likelihood of having HbA1c > 7.0% was increased in those infected than uninfected with H. pylori: prevalence ratio 1.11 (95% CI 1.00, 1.24), P = 0.04. For both sexes, total cholesterol (P = 0.004) and low-density lipoprotein (LDL) levels (P = 0.006) were higher among those infected than uninfected with H. pylori. No significant differences were found in glucose and HDL levels according to H. pylori infection. The results were consistent in unweighted multivariable analyses. In conclusion, H. pylori infection might be related to worse glycemic control in men, and higher total cholesterol and LDL cholesterol levels in both sexes.

Use of Fourier-Transform Infrared Spectroscopy (FT-IR) for Monitoring Experimental Helicobacter pylori Infection and Related Inflammatory Response in Guinea Pig Model. Int J Mol Sci 2020; 22:ijms22010281.

Abstract
Infections due to Gram-negative bacteria Helicobacter pylori may result in humans having gastritis, gastric or duodenal ulcer, and even gastric cancer. Investigation of quantitative changes of soluble biomarkers, correlating with H. pylori infection, is a promising tool for monitoring the course of infection and inflammatory response. The aim of this study was to determine, using an experimental model of H. pylori infection in guinea pigs, the specific characteristics of infrared spectra (IR) of sera from H. pylori infected (40) vs. uninfected (20) guinea pigs. The H. pylori status was confirmed by histological, molecular, and serological examination. The IR spectra were measured using a Fourier-transform (FT)-IR spectrometer Spectrum 400 (PerkinElmer) within the range of wavenumbers 3000–750 cm−1 and converted to first derivative spectra. Ten wavenumbers correlated with H. pylori infection, based on the chi-square test, were selected for a K-nearest neighbors (k-NN) algorithm. The wavenumbers correlating with infection were identified in the W2 and W3 windows associated mainly with proteins and in the W4 window related to nucleic acids and hydrocarbons. The k-NN for detection of H. pylori infection has been developed based on chemometric data. Using this model, animals were classified as infected with H. pylori with 100% specificity and 97% sensitivity. To summarize, the IR spectroscopy and k-NN algorithm are useful for monitoring experimental H. pylori infection and related inflammatory response in guinea pig model and may be considered for application in humans.

Abstract
Background: Several conducted studies have reported a higher and more frequent Helicobacter pylori infection rate in type 2 diabetes mellitus (T2DM). The aim of this study was to investigate the prevalence and its association between H. pylori infection and T2DM. Materials and Methods: A case and control study was conducted based on 529 T2DM patients and 529 control. H. pylori was assessed by Serum anti-H. pylori immunoglobulin G (IgG) and IgA. Furthermore, patients were investigated for fasting blood glucose (FBG) levels, glycosylated hemoglobin (HbA1c), serum cholesterol, and other biochemistry parameters. Results: The findings showed a positive significantly higher antibody titer for H. pylori infection (IgA > 250) in diabetic patients (50.7%) compared to controls (38.2%) (P < 0.001). Similarly, H. pylori infection for IgG > 300 titer was higher in T2DM patients (73.5%) compared to controls 61.8%) (P < 0.001). Further, the mean values were statistically significant diabetes with H. pylori infection for IgG > 300 titer and IgA > 250 titer, regarding Vitamin D, HbA1C (P < 0.001), FBG, calcium, creatinine, total cholesterol, LHDL, triglyceride levels, uric acid, bilirubin, thyroid-stimulating hormone (TSH), and systolic and diastolic blood pressure. The diabetic patients showed higher prevalence rate of symptoms than controls included: hypertension (14.3%), vomiting (15.5%), muscular symptoms (35.2%), bloating/distension (13.2%), abdominal pain (17%), nausea (9.6%), anemia (17%), kidneys (20.8%), chronic bronchitis (14.7%), gastrointestinal (23.8%), and diarrhea (20.4%). Conclusions: The current study revealed that H. pylori infections were significantly higher in diabetic patients compared to controls. Furthermore, T2DM patients infected with H. pylori positive reported a higher prevalence rate of symptoms than H. pylori negative.

Abstract
Diabetic mellitus patients are usually prone to chronic infections. However, there have been contradictory reports about the association between H. pylori infection and type II diabetes. The present study is aimed at evaluating the prevalence of Helicobacter pylori infection among type 2 dyspeptic diabetic patients in the littoral region of Cameroon. This cross sectional study comprised 93 type 2 diabetic dyspeptic patients and 112 non-diabetic dyspeptic patients attending the Gastroenterology Department at two reference hospitals in Douala-Cameroon. The study was approved by the local Ethical Committee of Medical Sciences. Participants were screened for the presence of both type 2 diabetes and H. pylori infection. Body mass index (BMI) of all the participants was also recorded. Data was analyzed using SSPS statistical package. H. pylori infection was found in 73.11% of diabetic patients versus 58.05% in non-diabetic participants, this difference was found to be significant (OR = 1.472, p = 0.0279). This relationship persists even when adjusted to factors such as age and income level of participants. Infected participants from age group ≥ 55 years and those with high income were those with a higher risk to develop diabetes. Infected patients with high BMI were more prone to develops diabetic mellitus compared with infected patients with normal BMI (p = 0.0034). Also, participant with high BMI were more prone to develops diabetic mellitus whether they were infected or not. Patients having both H. pylori + ve and BMI ≥ 25 kg/m2 were significantly more affected by diabetic mellitus than those in the others combined groups (p < 0.0001), suggested that high BMI and H. pylori infection together or not are factors that favor diabetes mellitus development. Separately or not, H. pylori infection and high BMI were risk factor for diabetes mellitus in our milieu.

Abstract
BACKGROUND There are several studies with varied and mixed results about the possible relationship between H. pylori and diabetes. Therefore, this current meta-analysis performed to determine the association between H. pylori infection and the risk of diabetes mellitus. METHODS A systematic literature searches of international databases, including Medline (PubMed), Web of Sciences, Scopus, EMBASE, and CINHAL (January 1990-March 2019) was conducted to identify studies investigating the relationship between H. pylori infection and diabetes mellitus. Only case-control studies were analyzed using odds ratio (OR) with 95% confidence intervals (CIs). Stratified and subgroup analyses were performed to explore heterogeneity between studies and assess effects of study quality. Logarithm and standard error logarithm odds ratio (OR) were also used for meta-analysis. RESULTS A total of 41 studies involving 9559 individuals (case; 4327 and control; 5232) were analyzed. The pooled estimate of the association between H. pylori infection with diabetes was OR = 1.27 (95% CI 1.11 to 1.45, P = 0.0001, I2 = 86.6%). The effect of H. pylori infection on diabetes mellitus (both types), type 1 and type 2 diabetes was 1.17 (95% CI 0.94 to 1.45), 1.19 (95% CI 0.98 to 1.45), and 1.43 (95% CI 1.11 to 1.85) respectively. Subgroup analysis by the geographical regions showed in Asian population risk of the effect of H. pylori infection on diabetes was slightly higher than other population, CONCLUSION: In overall a positive association between H. pylori infection and diabetes mellitus was found.

Abstract
BACKGROUND Reports on Helicobacter pylori infection in diabetics are inconsistent and contradictory. This study attempted to identify the possible association between type 2 diabetes and H. pylori infection. MATERIALS AND METHODS Following a cross-sectional design, participants were recruited from four National Guard Primary Health Care Centers in Jeddah City, Saudi Arabia. The study was conducted from December 2017 to November 2018. All participants underwent hemoglobin A1C (HbA1c) assessment and stool antigen test for H. pylori. RESULTS A total of 212 type 2 diabetic patients aged 40 years or more, and 209 age-matched nondiabetic subjects were included in the study. About one-quarter of the diabetics and nondiabetics were positive for H. pylori (26.9% and 26.3%, respectively). There was no significant difference. The prevalence of H. pylori did not differ significantly in the type 2 diabetics, with regard to their age groups, gender, smoking status, body mass index, chronic diseases, their HbA1c level, duration of diabetes, or received type of therapy. The prevalence of H. pylori was significantly higher in overweight and obese nondiabetic subjects (P = 0.013). Obese participants in both groups had the highest prevalence of infection (57.9% and 54.5%, respectively, P = 0.038). CONCLUSION About one-quarter of type 2 diabetics and nondiabetics in Jeddah City have H. pylori infection. There is no association between diabetes and H. pylori infection. H. pylori was significantly higher in patients with a high body mass index.

Helicobacter pylori eradication improves glycemic control in type 2 diabetes patients with asymptomatic active Helicobacter pylori infection. J Diabetes Investig 2019; 10:1092-1101. [PMID: 30556347 PMCID: PMC6626959 DOI: 10.1111/jdi.12991] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Revised: 12/04/2018] [Accepted: 12/13/2018] [Indexed: 12/29/2022] Open
Abstract
AIMS/INTRODUCTION Helicobacter pylori infection is associated with insulin resistance and glycemia in non-diabetes. However, the relationship between H. pylori infection and glycemia in diabetes remains inconclusive. Therefore, we explored the effect of H. pylori infection status and its eradication on glycemic control and antidiabetic therapy in type 2 diabetes patients. MATERIALS AND METHODS A total of 549 diabetes patients were recruited for sequential two-step approach (immunoglobulin G [IgG] serology followed by 13 C-urea breath test [UBT]) to discriminate "active" (IgG+ and UBT+) from "non-active" (UBT- or IgG-) H. pylori infection, and "past" (IgG+ but UBT-) from "never/remote" (IgG-) infection. The differences in hemoglobin A1c (A1C) and antidiabetic regimens between groups were compared. In the "active" infection group, the differences in A1C changes between participants with and without 10-day eradication therapy were compared after 3 months. RESULTS Despite no between-group difference in A1C, the "active" infection group (n = 208) had significantly more prescriptions of oral antidiabetic drug classes (2.1 ± 1.1 vs 1.8 ± 1.1, P = 0.004) and higher percentages of sulfonylurea use (67.3% vs 50.4%, P < 0.001) than the "non-active" infection group (n = 341). There were no differences in A1C and oral antidiabetic drug classes between "past" (n = 111) and "never/remote" infection groups (n = 230). Compared with the non-eradication group (n = 99), the eradication group (n = 98) had significant within-group (-0.17 ± 0.80%, P = 0.036) and between-group (-0.23 ± 0.10%, P = 0.024) improvements in A1C. CONCLUSIONS Diabetes patients with active H. pylori infection need higher glycemic treatment intensity to achieve comparable glycemia. Furthermore, H. pylori eradication decreases A1C, and thus improves glycemic control.

Abstract
BACKGROUND This multicenter study was undertaken to determine the prevalence of Helicobacter pylori (H. pylori) infection among dyspeptic patients with and without type 2 diabetes mellitus (T2DM). METHODS Patients with dyspepsia were recruited from tertiary teaching hospitals, three in the South-West and one in the South-South regions of Nigeria, between November 2016 and August 2017. The participants had breath samples analyzed for H. pylori by the Urea Breath Test (UBT) following manufacturer's instructions. Dyspeptic patients who were diagnosed previously with T2DM were recorded. Crosstab using chi-square and correlation analyses were used to test (hypothesis) variables. RESULTS The entire cohort included 471 dyspeptics, 19 (4%) of whom had T2DM. H. pylori infection was reported in 232/471 (49.3%) dyspeptics and 13/19 T2DM patients, without significant difference between diabetics and nondiabetics. The majority (84.6%) of those positive for UBT and T2DM were in the age group 52-71 years, while none was in the age group 72-91 years. There was no statistical significance (P>0.05) between the age group, UBT and T2DM positive. CONCLUSIONS Our study showed that, in Nigeria, there is no difference in prevalence of H. pylori in dyspeptic patients with and without T2DM.

Abstract
Helicobacter pylori is one of the most common human pathogens that can cause gastrointestinal (GI) disorders, including simple gastritis, gastric ulcer, and malignant gastritis. In some cases, such as immunodeficiency and underlying diseases, it can be problematic as opportunistic infections. Diabetes mellitus (type 2) (T2DM) is one of the H. pylori underlying diseases. Since GI problems are observed in diabetic patients, it is necessary to treat H. pylori infection. In this review, we aimed to evaluate the possible relationship between H. pylori and T2DM according to epidemiological surveys of 70 studies retrieved from databases, including Scopus, PubMed, and Google Scholar about the relationship between H. pylori and T2DM, and discuss the reported background mechanisms of this correlation. According to the results of our study, the different studies have shown that H. pylori is more prevalent in Type 2 diabetic patients than healthy individuals or nondiabetic patients. The reason is development of H. pylori infection-induced inflammation and production of inflammatory cytokines as well as different hormonal imbalance by this bacterium, which are associated with diabetes mellitus. On the other hand, by tracing anti-H. pylori antibodies in patients with diabetes mellitus and occurrence of symptoms such as digestive problems in >75% of these patients, it can be concluded that there is a relationship between this bacterium and T2DM. Considering the evidence, it is crucially important that the probability of infection with H. pylori is evaluated in patients with T2DM so that medical process of the patient is followed with higher cautious.

Abstract
OBJECTIVE To compare Helicobacter pylori (H. pylori) eradication rate of type 2 diabetic patients with non-diabetic subjects. METHODS In this multicenter prospective observational study, H. pylori-infected subjects were enrolled from three university-affiliated hospitals. Eradication regimen was triple therapy with standard dose of proton pump inhibitors (b.i.d), amoxicillin (1.0 g b.i.d), and clarithromycin (500 mg b.i.d) for 7 days. Urea breath test was performed 4 weeks after treatment. Various clinical and laboratory data were collected for identification of factors associated with successful eradication. RESULTS Totally, 144 subjects were enrolled and 119 (85 non-diabetic and 34 diabetic patients) were finally analyzed. Eradication rate was 75.6% and there was no difference between diabetic patients and non-diabetic subjects (73.5% vs 76.5%, p value: 0.814). Adverse drug reactions were reported in 44.5% of patients. In multivariate analysis for predicting H. pylori eradication in diabetic patients, HbA1c (⩾7.5%) was a significant factor affecting eradication rate (adjusted odds ratio: 0.100, 95% confidence interval: 0.011-0.909, p value: 0.041). CONCLUSION Diabetes itself is not a major factor affecting H. pylori eradication. However, poor glucose control may harmfully affect H. pylori eradication.

Abstract
BACKGROUND The association between Helicobacter pylori infection and glycated hemoglobin A has been confirmed in many studies, but these conclusions are still contradictory and controversial. Therefore, we conducted a meta-analysis to resolve the problem of inconsistent results in diabetes. METHODS A comprehensive search was conducted on related researches published in PubMed, Embase, and China Academic Journal Full-text Database (CNKI) from the inception of each database to April 2019. Fixed or random effects model was used to pool the weighted mean difference with 95% confidence interval from individual studies. Subgroup and sensitivity analyses were also performed. Publication bias was estimated by funnel plot, Egger's test, and fail-safe numbers. RESULTS 35 studies with 4,401 participants with diabetes were included in the meta-analysis. Glycated hemoglobin A levels were elevated in patients with Helicobacter pylori infection compared with patients without Helicobacter pylori infection (WMD = 0.50, 95% CI: 0.28-0.72, p < 0.001). In subgroup analysis by the subtype of diabetes, there was a correlation between Helicobacter pylori infection and elevated glycated hemoglobin A in type 1 diabetes (I 2 = 74%, p < 0.001, WMD = 0.46, 95% CI: 0.12-0.80), and in type 2 diabetes (I 2 = 90%, p < 0.001, WMD = 0.59, 95% CI: 0.28-0.90, p < 0.001). In subgroup analysis by the study design, there was a correlation in cross-sectional study (I 2 = 89%, p < 0.001, WMD = 0.42, 95% CI: 0.16-0.69, p ≤ 0.003) and in case-control study (I 2 = 83%, p < 0.001, WMD = 0.39, 95% CI: 0.14-0.64, p ≤ 0.003). By different methods for detecting Helicobacter pylori, there was a correlation in the biopsy group (I 2 = 83%, p < 0.001, WMD = 0.6, 95% CI: 0.11-1.09, p ≤ 0.03) and in other groups of test methods (I 2 = 87%, p < 0.001, WMD = 0.37, 95% CI: 0.17-0.56, p < 0.001). Sensitivity analysis showed that our results were reliable, and no evidence of substantial publication bias was detected. CONCLUSION The meta-analysis might indicate a correlation between Helicobacter pylori infection and glycated hemoglobin A levels in diabetes.

Association between gastrointestinal tract infections and glycated hemoglobin in school children of poor neighborhoods in Port Elizabeth, South Africa. PLoS Negl Trop Dis 2018; 12:e0006332. [PMID: 29543807 PMCID: PMC5871004 DOI: 10.1371/journal.pntd.0006332] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2017] [Revised: 03/27/2018] [Accepted: 02/21/2018] [Indexed: 12/11/2022] Open
Abstract
Background Low- and middle-income countries are facing a dual disease burden with infectious diseases (e.g., gastrointestinal tract infections) and non-communicable diseases (e.g., diabetes) being common. For instance, chronic parasite infections lead to altered immune regulatory networks, anemia, malnutrition, and diarrhea with an associated shift in the gut microbiome. These can all be pathways of potential relevance for insulin resistance and diabetes. The aim of this study was to investigate the association between common gastrointestinal tract infections and glycemia in children from non-fee paying schools in South Africa. Methodology We conducted a cross-sectional survey among 9- to 14-year-old school children in Port Elizabeth. Stool and urine samples were collected to assess infection status with parasitic worms (e.g., Ascaris lumbricoides, Enterobius vermicularis, and Trichuris trichiura), intestinal protozoa (e.g., Cryptosporidium parvum and Giardia intestinalis), and the bacterium Helicobacter pylori. Glycated hemoglobin (HbA1c) was measured in finger prick derived capillary blood. All children at schools with a high prevalence of helminth infections and only infected children at the schools with low infection rates were treated with albendazole. The association of anthelmintic treatment with changes in HbA1c 6 months after the drug intervention was also investigated. Findings A high prevalence of 71.8% of prediabetes was measured in this group of children, with only 27.8% having HbA1c in the normal range. H. pylori was the predominant infectious agent and showed an independent positive association with HbA1c in a multivariable regression analysis (β = 0.040, 95% confidence interval (CI) 0.006–0.073, p<0.05). No association of HbA1c with either any other infectious agent or albendazole administration was found. Conclusion The role of H. pylori in diabetes needs confirmation in the context of longitudinal treatment interventions. The specific effect of other gastrointestinal tract infections on glycemia remains unclear. Future studies should integrate the measurement of biomarkers, including immunological parameters, to shed light on the potential mediating mechanisms between parasite infections and diabetes. Parasitic worms (e.g., pinworm, roundworm, and whipworm), intestinal protozoa (e.g., Cryptosporidium parvum and Giardia intestinalis), and the bacterium Helicobacter pylori persist at high rates in the gastrointestinal tract of people from low- and middle-income countries. These infectious agents are increasingly paralleled by high rates of non-communicable diseases, such as diabetes. We studied the association of glycemia, measured as HbA1c with common gastrointestinal tract infections among school children aged 9–14 years from disadvantaged neighborhoods in Port Elizabeth, South Africa. Our goal was to deepen the understanding of whether specific gastrointestinal tract infections might be early life determinants of elevated HbA1c levels that might lead to diabetes. We found that the bacterium H. pylori was very common among our group of children with a positive association with hyperglycemia. None of the other infectious agents showed such an association. Additional, longitudinal studies are needed to determine whether there is causality for the observed association between H. pylori and hyperglycemia. The integration of biomarkers will allow studying mediating mechanisms.

Abstract
BACKGROUND Evidence is conflicting regarding the association between Helicobacter pylori infection and diabetes mellitus. The study objective was to examine associations of H. pylori infection, gastric ulcers and duodenal ulcers, with diabetes mellitus. METHODS This cross-sectional study was undertaken using coded data from the computerized database of Maccabi Health Services in Israel, on 147,936 individuals aged 25-95 years who underwent the urea breath test during 2002-2012. Multiple logistic regression models were conducted, while adjusting for known risk factors for diabetes mellitus. RESULTS A H. pylori positive test was recorded for 76,992 (52.0%) individuals and diabetes for 12,207 (8.3%). The prevalence of diabetes was similar in individuals with and without H. pylori infection, but this association was modified (P for heterogeneity 0.049) by body mass index (BMI): adjusted odds ratio (aOR) 1.16 (95% confidence intervals (CI) 1.04-1.29) in persons with BMI<25 kg/m2 versus aOR 1.03 (95% CI 0.98-1.08) in persons with BMI≥25 kg/m2. Diabetes mellitus prevalence was higher in persons with gastric (aOR 1.20 (95% CI 1.06-1.34)) and duodenal ulcers (aOR 1.20 (95% CI 1.12-1.28)) compared to persons without these diagnoses. CONCLUSIONS In this large population-based study, we demonstrated significant positive associations, albeit of small magnitude, of H. pylori infection and peptic disease with diabetes. The long-term gastric inflammation and associated-damage to the gastric mucosa might play a role in such associations.

Helicobacter pylori Infection Is Associated with Type 2 Diabetes, Not Type 1 Diabetes: An Updated Meta-Analysis. Gastroenterol Res Pract 2017; 2017:5715403. [PMID: 28883831 PMCID: PMC5572635 DOI: 10.1155/2017/5715403] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2017] [Accepted: 05/14/2017] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Extragastric manifestations of Helicobacter pylori (H. pylori) infection have been reported in many diseases. However, there are still controversies about whether H. pylori infection is associated with diabetes mellitus (DM). This study was aimed at answering the question. METHODS A systematic search of the literature from January 1996 to January 2016 was conducted in PubMed, Embase databases, Cochrane Library, Google Scholar, Wanfang Data, China national knowledge database, and SinoMed. Published studies reporting H. pylori infection in both DM and non-DM individuals were recruited. RESULTS 79 studies with 57,397 individuals were included in this meta-analysis. The prevalence of H. pylori infection in DM group (54.9%) was significantly higher than that (47.5%) in non-DM group (OR = 1.69, P < 0.001). The difference was significant in comparison between type 2 DM group and non-DM group (OR = 2.05), but not in that between type 1 DM group and non-DM group (OR = 1.23, 95% CI: 0.77-1.96, P = 0.38). CONCLUSION Our meta-analysis suggested that there is significantly higher prevalence of H. pylori infection in DM patients as compared to non-DM individuals. And the difference is associated with type 2 DM but not type 1 DM.

Abstract
Gastric atrophy results in lower plasma ghrelin, higher gastrin secretion, a change in gut microbiota, and altered dietary nutrient absorption, which may be associated with the incidence of diabetes. Helicobacter pylori (H. pylori) infection is a major cause of gastric atrophy and is associated with diabetes in some reports. Since there is no study which investigates the impact of gastric atrophy on diabetes, we conduct a prospective cohort study to examine the relationship between H. pylori infection, gastric atrophy, and incident diabetes. In this study, subjects with gastric atrophy had a lower risk of incident diabetes, compared to those without gastric atrophy. The extent of gastric atrophy, measured by serum pepsinogen (PG) I/II ratio, was correlated with age, H. pylori IgG titer, HOMA2-IR, and HOMA2%B. When gastric atrophy is more extensive, presented as a lower serum PG I/II ratio, the risk of incident diabetes is lower. On the other hand, there was no significant association between H. pylori infection and the incidence of diabetes. In conclusion, the presence and the extent of gastric atrophy, but not H. pylori infection, are associated with incident diabetes. Further studies are needed to investigate the detailed mechanisms and the potential applications of the findings to guide diabetes screening and treatment strategies.

Abstract
Strong epidemiologic evidence and common molecular mechanisms support an association between Alzheimer's disease (AD) and type 2-diabetes. Local inflammation and amyloidosis occur in both diseases and are associated with periodontitis and various infectious agents. This article reviews the evidence for the presence of local inflammation and bacteria in type 2 diabetes and discusses host pathogen interactions in chronic inflammatory disorders. Chlamydophyla pneumoniae, Helicobacter pylori and spirochetes are demonstrated in association with dementia and brain lesions in AD and islet lesions in type 2 diabetes. The presence of pathogens in host tissues activates immune responses through Toll-like receptor signaling pathways. Evasion of pathogens from complement-mediated attack results in persistent infection, inflammation and amyloidosis. Amyloid beta and the pancreatic amyloid called amylin bind to lipid bilayers and produce Ca(2+) influx and bacteriolysis. Similarly to AD, accumulation of amylin deposits in type 2 diabetes may result from an innate immune response to chronic bacterial infections, which are known to be associated with amyloidosis. Further research based on an infectious origin of both AD and type 2 diabetes may lead to novel treatment strategies.

Abstract
Background. Type 1 diabetes (T1D) and type 2 diabetes (T2D) have been linked to Helicobacter pylori infection, although results are conflicting. No previous study addressed a possible link between H. pylori infection and latent autoimmune diabetes in adults (LADA). In this study, a correlation among H. pylori infection and the risk of autoimmune diabetes in comparison with T2D was investigated. Methods. Sera from 234 LADA patients, 105 patients with late-onset T1D, and 156 patients with T2D were analyzed for anti-H. pylori and the cytotoxin-associated antigen (CagA) IgG antibodies. Results. H. pylori seroprevalence was comparable in LADA (52%), late-onset T1D (45%), and T2D (49%) with no gender differences. The seroprevalence of CagA IgG was significantly higher in autoimmune diabetes (late-onset T1D: 45%, LADA: 40%) compared to T2D (25%; p < 0.028). Conclusions. Although H. pylori seroprevalence was similar in LADA, T1D, and T2D, anti-CagA positivity was significantly increased among patients with autoimmune diabetes, suggesting that more virulent H. pylori strains might be a trigger for immune mechanisms involved in their pathogenesis.

Abstract
BACKGROUND Although the association of Helicobacter pylori (H. pylori) infection with diabetes mellitus has been evaluated, findings are controversial. This study investigated the association in a Chinese population. METHODS A cross-sectional study, including a total of 30 810 subjects from the Dongfeng-Tongji Cohort study, was conducted. H. pylori status was measured via (14) C urea breath test. Association analysis was performed by logistic regression, with multivariable adjustment for sex, age, body mass index, smoking, alcohol consumption, family history of diabetes, physical activity and the use of antibiotics. RESULTS Among a middle-age and old-age Chinese population, individuals with H. pylori infection also had a higher prevalence of type 2 diabetes (21.3% versus 20.2%, p = 0.026). H. pylori infection was associated with higher risk of type 2 diabetes [odds ratio, 1.08 (95% confidence interval: 1.02-1.14); p = 0.008] after adjustment for other confounders. The association was significant among women, those who were above 65 years old, not overweight or obese, and those who did not smoke, did not consume alcohol and without family history of diabetes. However, there was no interaction between H. pylori infection and other traditional risk factors on type 2 diabetes risk. Subjects with H. pylori infection had a lower level of high-density lipoprotein cholesterol (p < 0.0001) and higher levels of blood pressure (p < 0.001), total cholesterol, HbA1c and fasting blood glucose (p < 0.0001) than those who did not. CONCLUSIONS These findings suggested that H. pylori infection was associated with the risk of type 2 diabetes in a middle-age and old-age Chinese population. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract
Several case-control studies have reported that patients with diabetes mellitus (DM) had a higher prevalence of Helicobacter pylori infection than those without DM, but these findings remain equivocal. Additionally, there are few studies examining associations between East Asian CagA-positive H. pylori and DM. This cross-sectional study aimed to investigate whether H. pylori infection was a possible risk factor for DM in a general Japanese population. The study included 5165 subjects (1467 men, 3698 women) aged 35–69 years from the Daiko Study, part of the Japan Multi-Institutional Collaborative Cohort Study. A urinary anti-H. pylori antibody was used to detect H. pylori infection. The medical history of physician-diagnosed DM was confirmed by self-administered questionnaire. The odds ratios (ORs) and their 95 % confidence intervals (CIs) for DM (current and former) were calculated using unconditional logistic regression analysis, adjusting for age, sex, educational status, alcohol use, smoking status, body mass index, energy intake, and physical activity. The prevalence of DM was 4.6 % (95 % CI 3.7–5.6 %) among 1878 participants with H. pylori infection and 3.2 % (2.6–3.8 %) among 3287 without the infection (p = 0.009). The crude, age-adjusted, and multivariate-adjusted ORs for DM in those with the infection relative to those without were 1.47 (95 % CI 1.10–1.97), 1.02 (0.76–1.38), and 0.97 (0.71–1.32), respectively. We found a significantly higher DM prevalence among those with H. pylori infection than among those without. However, almost all the difference in prevalence could be explained by the older age of those infected. Our findings did not support an association between H. pylori infection and DM.

Abstract
Helicobacter pylori (HP) is a common worldwide infection with known gastrointestinal and nongastrointestinal complications. One of the gastrointestinal side effects posed for this organism is its role in diabetes and increased insulin resistance. The aim of this study was to evaluate the association between HP and insulin resistance in type 2 diabetic patients and nondiabetics. This cross-sectional study was carried out from May to December 2013 on 211 diabetic patients referred to diabetes clinic of Shahid Beheshti Hospital of Qom and 218 patients without diabetes. HP was evaluated using serology method and insulin resistance was calculated using HOMA-IR. The prevalence of H. pylori infection was 55.8% and 44.2% in diabetics and nondiabetics (P = 0.001). The study population was divided into two HP positive and negative groups. Among nondiabetics, insulin resistance degree was 3.01 ± 2.12 and 2.74 ± 2.18 in HP+ and HP- patients, respectively (P = 0.704). Oppositely, insulin resistance was significantly higher in diabetic HP+ patients rather than seronegative ones (4.484 ± 2.781 versus 3.160 ± 2.327, P = 0.013). In diabetic patients, in addition to higher prevalence of HP, it causes a higher degree of insulin resistance.

Abstract
BACKGROUNDS AND AIM The association between Helicobacter pylori infection and diabetes was inconsistent in previous studies. Moreover, there are no studies on the relationship between H. pylori infection and prediabetes in the literature. The aim of this study is thus to assess the association of Helicobacter infection, diagnosed by pathology from gastric biopsy, with diabetes and prediabetes. METHODS This cross-sectional study included 1285 subjects aged 19-85 who underwent esophagogastroduodenoscopy and gastric biopsy during health examinations at National Cheng Kung University Hospital from 2000 to 2009. Subjects were divided into three groups, including normal glucose tolerance, prediabetes, and diabetes. Diabetes and prediabetes were assessed according to the American Diabetes Association diagnostic criteria. Gastric Helicobacter infection was an independent variable. Chi-square tests, analysis of variance, and multinomial logistic regression models were used to analyze the effects of Helicobacter infection on the risk of diabetes and prediabetes while controlling for age, lifestyle, pathological conditions, and laboratory variables. RESULTS There were significant differences in the prevalence of gastric Helicobacter infection among the three groups. The results of multivariate analysis showed that age, obesity, family history of diabetes, hypertension, and hypertriglyceridemia were significantly related to both prediabetes and diabetes. Helicobacter pylori infection was positively associated with diabetes (odds ratio [OR] 1.42, 95% confidence interval [CI] 1.01-2.01), but not prediabetes (OR 1.02, 95% CI 0.77-1.36), in addition to male gender, education level (≤ 9 vs > 12 years), pre-hypertension, and low high-density lipoprotein cholesterol. CONCLUSIONS Gastric H. pylori infection is associated with diabetes, but not prediabetes.

Abstract
INTRODUCTION Helicobacter pylori (H. pylori) infection has been associated with increased levels of inflammatory cytokines and subsequent insulin resistance and epidemiologically linked to type 2 diabetes. OBJECTIVES To study the prevalence rate of H. pylori infection in type 2 diabetes and its relation with HbA1C levels. MATERIALS AND METHODS In this cross-sectional case-control study, 80 patients (≥18 years) who met the Americans with Disabilities Act (ADA) criteria for diabetes were recruited. Similarly, 60 age, sex, and education matched healthy controls were taken. They were tested for H. pylori infection by rapid urease test, histological examination of antral endoscopic biopsy specimens and serology. The relationship between H. pylori infection and levels of plasma glucose and HbA1C was assessed. RESULTS Out of the 80 patients of type 2 diabetes, H. pylori infection was found in 62 (77.5%) while it was present in only 35 (58.3%) of 60 controls, which was found to be significant (Chi-square test: 5.919, df = 1, P value = 0.015). Mean HbA1C among diabetics with H. pylori infection was 8.19 ± 1.16% and without H. pylori infection was 6.9 ± 0.84% (t = 4.3872, P value = 0.0001). CONCLUSIONS Prevalence of H. pylori infection was significantly higher in diabetes as compared to controls. Presence of H. pylori infection significantly correlated with the level of HbA1C.

Abstract
Helicobacter pylori (H. pylori) is still the most prevalent infection of the world. Colonization of the stomach by this agent will invariably induce chronic gastritis which is a low-grade inflammatory state leading to local complications (peptic ulcer, gastric cancer, lymphoma) and remote manifestations. While H. pylori does not enter circulation, these extragastric manifestations are probably mediated by the cytokines and acute phase proteins produced by the inflammed mucosa. The epidemiologic link between the H. pylori infection and metabolic changes is inconstant and controversial. Growth delay was described mainly in low-income regions with high prevalence of the infection, where probably other nutritional and social factors contribute to it. The timely eradication of the infection will lead to a more healthy development of the young population, along with preventing peptic ulcers and gastric cancer An increase of total, low density lipoprotein and high density liporotein cholesterol levels in some infected people creates an atherogenic lipid profile which could promote atherosclerosis with its complications, myocardial infarction, stroke and peripheral vascular disease. Well designed and adequately powered long-term studies are required to see whether eradication of the infection will prevent these conditions. In case of glucose metabolism, the most consistent association was found between H. pylori and insulin resistance: again, proof that eradication prevents this common metabolic disturbance is expected. The results of eradication with standard regimens in diabetics are significantly worse than in non-diabetic patients, thus, more active regimens must be found to obtain better results. Successful eradication itself led to an increase of body mass index and cholesterol levels in some populations, while in others no such changes were encountered. Uncertainities of the metabolic consequences of H. pylori infection must be clarified in the future.

Abstract
Objective: To evaluate H. pylori infection and virulent strain in diabetic children. Patients: In this study 53 type 1 diabetics and 53 of normal volunteers were included. Methods: All studied children were subjected to assessment of glycosylated hemoglobin (HbA1), Anti H. pylori antibodies (IgA, IgG, IgM), Anti-cytotoxin associated gene A antibodies (Anti Cag A IgG). Results: Anti H. pylori antibodies IgA, IgG, total antibodies and anti Cag A IgG were significantly higher in diabetics. Diabetic patients with positive anti Cag A IgG had a lower age of onset of diabetes, higher age of patients, body mass index (BMI) and HbA1. Conclusion: High prevalence of infection with the virulent strain of H. pylori among diabetic children with older age, large BMI, high HbA1 and younger age of onset of disease. The screening for the virulent strain in diabetic patients with poor metabolic control is mandatory. Control of diabetes is essential to present the infection with H. pylori.

Abstract
Helicobacter pylori (H. pylori) is a highly prevalent, serious and chronic infection that has been associated causally with a diverse spectrum of extragastric disorders including iron deficiency anemia, chronic idiopathic thrombocytopenic purpura, growth retardation, and diabetes mellitus. The inverse relation of H. pylori prevalence and the increase in allergies, as reported from epidemiological studies, has stimulated research for elucidating potential underlying pathophysiological mechanisms. Although H. pylori is most frequently acquired during childhood in both developed and developing countries, clinicians are less familiar with the pediatric literature in the field. A better understanding of the H. pylori disease spectrum in childhood should lead to clearer recommendations about testing for and treating H. pylori infection in children who are more likely to develop clinical sequelae. A further clinical challenge is whether the progressive decrease of H. pylori in the last decades, abetted by modern clinical practices, may have other health consequences.

Abstract
OBJECTIVE. To assess the association between Helicobacter pylori (HP) infection and glycemic control in patients with diabetes through a meta-analytic approach. RESEARCH DESIGN AND METHODS. Electronic literature searches were conducted for cross-sectional studies that examined the hemoglobin A1c (A1C) level by whether patients with diabetes were or were not carriers of HP. Mean differences in A1C between groups with and without HP infection were pooled with a random-effects model. RESULTS. Thirteen eligible studies were included in this meta-analysis. Overall, the HP carriers did not have significantly higher A1C levels compared with HP noncarriers (mean difference (95% CI), 0.19% (-0.18 to 0.46), P = 0.16). When the analysis was limited to studies targeting patients with type 1 diabetes, there was also no significant difference in A1C (0.69% (-0.31 to 1.68), P = 0.18). CONCLUSIONS. There was insufficient evidence that HP infection worsened glycemic control in patients with diabetes.

Abstract
BACKGROUND Helicobacter pylori infects more than half of the world's population. The aim of this study was to quantify the association between H. pylori infection and the risk of diabetes mellitus and diabetic nephropathy, and to detect at which stage the infection might have higher pathogenicity in the disease-free status-diabetes mellitus-diabetic nephropathy process. METHODS A literature search was performed to identify studies published between 1997 and 2012 for relative risk estimates. Fixed and random effects meta-analytical techniques were conducted for diabetes mellitus and diabetic nephropathy. RESULTS Thirty-seven case-control studies and 2 cohort studies were included. H. pylori was associated with an increased risk of each type of diabetes mellitus (odds ratio (OR) 2.00, 95% confidence interval (CI) 1.82-2.20, p for heterogeneity = 0.07). The infection was also associated with increased risks of type 1 and type 2 diabetes mellitus, separately (OR 1.99, 95% CI 1.52-2.60, p for heterogeneity = 0.15, and OR 2.15, 95% CI 1.81-2.55, p for heterogeneity = 0.24, respectively). In addition, we found a significant association between H. pylori infection and diabetic nephropathy risk (OR 1.60, 95% CI 1.10-2.33, p for heterogeneity = 0.44). CONCLUSIONS Our meta-analyses suggest a relationship between H. pylori infection and the risk of diabetes mellitus and diabetic nephropathy. The bacterium may be able to play its pathogenic role in the whole disease process, and this action may be stronger in type 2 diabetic patients than in type 1 diabetic patients.

Abstract
BACKGROUND Although the association between chronic Helicobacter pylori infection and type 2 diabetes has been suggested, findings have been inconsistent. This study evaluated the association between chronic H. pylori infection and glucose regulation. MATERIALS AND METHODS We evaluated H. pylori infection status of participants recruited from the gastroenterology clinic at our hospital. At baseline, we performed blood tests including fasting plasma glucose, insulin, glycated haemoglobin A1c (HbA1c) and other biochemical measurements. Insulin resistance and beta-cell function were assessed by homoeostasis model assessment (HOMA-IR and HOMA-B, respectively). RESULTS A total of 2070 participants were recruited. Those who had H. pylori infections had higher serum HbA1c levels and lower HOMA-B than those who did not (5.78% vs. 5.69%, P = 0.01 and 53.85 + 38.43 vs. 60.64 + 43.40, P = 0.009, respectively). They also had a significantly higher prevalence of type 2 diabetes (8.97% vs. 5.57%, P= 0.02). Chronic H. pylori infection was significantly associated with high levels of HbA1c and type 2 diabetes in participants above 65 years old (P = 0.001) and decreased insulin secretion and sensitivity in those under 45 years (P = 0.05). CONCLUSIONS Long-term H. pylori infection is significantly associated with high levels of HbA1c and decreased insulin secretion in this Chinese population. Proper screening for H. pylori infection combined with regular monitoring of blood glucose and HbA1c levels might be effective for the early detection of glucose dysregulation and prevention of type 2 diabetes.

Abstract
Background Information about gastro-oesophageal reflux disease (GERD) in patients with Diabetes mellitus type 2 (T2D) is scarce, although the incidence of both disorders is increasing. We aimed to determine GERD symptoms and their underlying pathophysiologic characteristics in T2D patients. Methods This “retro-pro” study compared 65 T2D patients to a control group of 130 age- and sex-matched non-diabetics. GERD was confirmed by gastroscopy, manometry, pH-metry and barium swallow. Results In patients with T2D compared to controls, dysphagia (32.3% vs. 13.1%; p = 0.001) and globus sensation (27.7% vs. 13.8%; p = 0.021) were found more frequently, whereas heartburn (76.9% vs. 88.5%; p = 0.046) and regurgitation (47.7% vs. 72.3%; p = 0.001) were predominant in non-diabetics. Despite higher body mass indices (31.1 ± 5.2 vs. 27.7 ± 3.7 kg/m2; p < 0.001), hiatal hernia was less frequent in T2D patients compared to controls (60.0% vs. 90.8%, p < 0.001). Lower oesophageal sphincter (LES) pressure was higher in patients with T2D (median 10.0 vs. 7.2 mmHg, p = 0.016). DeMeester scores did not differ between the groups. Helicobacter pylori infections were more common in T2D patients (26.2% vs. 7.7%, p = 0.001). Barrett metaplasia (21.5% vs. 17.7%), as well as low- (10.8% vs. 3.8%) and high-grade dysplasia (1.5% vs. 0%) were predominant in T2D patients. Conclusions T2D patients exhibit different GERD symptoms, higher LES pressures and a decreased prevalence of hiatal hernia than non-diabetics, which may be related to worse oesophageal motility and, thus, a more functional rather than anatomical cause of GERD. Low-grade dysplasia was more than twice as high in T2D than in non-diabetics patients. Trial registration Ethics committee of the Medical University of Vienna, IRB number 720/2011.

Abstract
AIMS Some studies have shown Helicobacter pylori (H. pylori) infection to be associated with diabetes mellitus, but the relationship remains controversial. This meta-analysis was designed to quantify the association between H. pylori infection and diabetes. METHODS A computerized search of PubMed and Embase was carried out. Studies that provided data on H. pylori infection in both diabetes and control groups were selected. An unconditional logistic regression model was used to analyze potential parameters related to H. pylori prevalence. Subgroup analyses were conducted for types of diabetes, methods of detection, geographical distribution, hemoglobin A1c (HbA1c) levels and evidence grade. RESULT Forty-one studies were identified, involving 14,080 patients, with a total H. pylori infection rate of 42.29%. The OR for H. pylori infection was increased to 1.33 (95% CI: 1.08-1.64; P=0.008) among the patients with diabetes. Subgroup analysis revealed a significantly higher infection rate of H. pylori in the type 2 diabetes group versus the control group: OR=1.76, 95% CI: 1.40-2.21, P<0.00001. CONCLUSIONS The pooled data suggests a trend toward more frequent H. pylori infections in diabetes patients, especially in type 2 diabetes patients. As this is a meta-analysis of observational studies, more randomized controlled trials should be done in the future.

Abstract
OBJECTIVE Chronic infections could be contributing to the socioeconomic gradient in chronic diseases. Although chronic infections have been associated with increased levels of inflammatory cytokines and cardiovascular disease, there is limited evidence on how infections affect risk of diabetes. RESEARCH DESIGN AND METHODS We examined the association between serological evidence of chronic viral and bacterial infections and incident diabetes in a prospective cohort of Latino elderly. We analyzed data on 782 individuals aged >60 years and diabetes-free in 1998-1999, whose blood was tested for antibodies to herpes simplex virus 1, varicella virus, cytomegalovirus, Helicobacter pylori, and Toxoplasma gondii and who were followed until June 2008. We used Cox proportional hazards regression to estimate the relative incidence rate of diabetes by serostatus, with adjustment for age, sex, education, cardiovascular disease, smoking, and cholesterol levels. RESULTS Individuals seropositive for herpes simplex virus 1, varicella virus, cytomegalovirus, and T. gondii did not show an increased rate of diabetes, whereas those who were seropositive for H. pylori at enrollment were 2.7 times more likely at any given time to develop diabetes than seronegative individuals (hazard ratio 2.69 [95% CI 1.10-6.60]). Controlling for insulin resistance, C-reactive protein and interleukin-6 did not attenuate the effect of H. pylori infection. CONCLUSIONS We demonstrated for the first time that H. pylori infection leads to an increased rate of incident diabetes in a prospective cohort study. Our findings implicate a potential role for antibiotic and gastrointestinal treatment in preventing diabetes.

MATERIALS AND METHODS This hospital-based case-control study was conducted on 148 subjects and divided into two groups i.e. type 2 diabetics and non-diabetics; each group consisting of 74 patients. All diabetic patients of >/= 35 years of age, both gender and the known cases with history of dyspepsia, epigastric pain or bloating for more than a month were screened for Helicobacter pylori infection. The collected data of both groups was evaluated and separated for analysis. RESULTS Majority of the patients were male with mean age +/- SD, 52.86 +/- 8.51. Among the diabetic group, HpSA was positive in 54/74 (73%), whereas in the non-diabetic group HpSA was positive in 38/74 (51.4%) cases. Fasting blood glucose was identified as low in 04 (5.40%) H. pylori infected - diabetic patients where as the blood glucose level of 07 (9.45%) known diabetic patients was raised despite the ongoing medication. CONCLUSION Diabetic patients are more prone and at risk to acquire H. Pylori infection. Therefore proper monitoring of blood glucose level and screening for H. pylori infection are effective preventive measures for this life threatening infection.

Abstract
The pathogenesis, incidence, complication rates, response to acid suppression and Helicobacter pylori (H. pylori) eradication therapy in peptic ulcer associated with chronic disease such as liver cirrhosis, chronic renal failure, diabetes mellitus, and critically ill conditions are different from those with general population, so that the management strategies also should be differentiated. The eradication of H. pylori are not so effective for preventing recurrence of peptic ulcer in liver cirrhosis patients as shown in general population, and conservative managements such as preventing deterioration of hepatic function and decrease in portal pressure are mandatory to reduce the risk of ulcer recurrence. The standard triple therapy for H. pylori eradication are as effective in chronic renal failure patients as in normal population, but the frequency of side effects of amoxicillin is higher in the patients not receiving dialysis therapy. Delay in eradication therapy until beginning of dialysis therapy or modification of eradication regimen should be considered in such cases. High prevalence of asymptomatic peptic ulcers and increased mortality in complicated peptic ulcer disease warrant regular endoscopic surveillance in diabetic patients, especially with angiopathy. The prolongation of duration of eradication therapy also should be considered in diabetic patients with angiopathic complication because of lower eradication rate with standard triple regimens as compared to normal population. Prophylactic acid suppressive therapy is highly recommended in critically ill patients with multiple risk factors. Herein, we propose evidence-based treatment guidelines for the management of peptic ulcer disease in special conditions based on literature review and experts opinion.

Abstract
BACKGROUND The eradication rate of Helicobacter pylori with a standard triple regimen has been reported as being lower in patients with type 2 diabetes mellitus (DM) than in those without DM. The aim of this study was to evaluate the efficacy and tolerability of 2 different H. pylori eradication regimens in patients with type 2 DM. METHODS Ninety-eight consecutive type 2 DM and 116 nondiabetic age- and sex-matched patients were enrolled in this study. Patients were randomized to receive either pantoprazole, clarithromycin, and amoxicillin (PCA) for 14 days or ranitidine-bismuth citrate, clarithromycin, and amoxicillin (RCA) for 14 days as the eradication regimen. H. pylori eradication was assessed using C14-urea breath test 6 weeks after the end of therapy. RESULTS The H. pylori eradication rate with PCA regimen in patients with DM with both intention-to-treat (ITT) and per protocol (PP) analysis was 24/49 (48.9% and 62.9%) and in non-DM patients was 44/58 (75.9% and 86.7%) with ITT and 44/57 (77.2% and 88.2%) with PP analysis (P < 0.05). The H. pylori eradication rates with RCA regimen in patients with DM were 22/49 (45.9% and 59.8%) with ITT and 22/48 (45.8% and 59.9%) with PP analysis and in non-DM patients were 44/58 (75.9% and 86.7%) with ITT and 44/56 (78.6% and 89.3%) with PP analysis. CONCLUSIONS These data suggest that the eradication rate of H. pylori with PCA or RCA treatment is lower in patients with type 2 diabetes than in nondiabetics and that successful eradication could decrease dyspeptic symptoms.

Abstract
Helicobacter pylori (H pylori) infection is a leading world-wide infectious disease as it affects more than half of the world population and causes chronic gastritis, peptic ulcer disease and gastric malignancies. The infection elicits a chronic cellular inflammatory response in the gastric mucosa. However, the effects of this local inflammation may not be confined solely to the digestive tract but may spread to involve extra-intestinal tissues and/or organs. Indeed, H pylori infection has been epidemiologically linked to extra-digestive conditions and diseases. In this context, it has been speculated that H pylori infection may be responsible for various endocrine disorders, such as autoimmune thyroid diseases, diabetes mellitus, dyslipidemia, obesity, osteoporosis and primary hyperparathyroidism. This is a review of the relationship between H pylori infection and these endocrine disorders.

Abstract
AIM: To investigate the incidence of reflux esophagitis (RE) and H pylori infection in the diabetic patient.
METHODS: The incidence of RE and H pylori infection were investigated in 85 patients with diabetes mellitus and the results were compared with controls.
RESULTS: The incidence of RE in diabetic patients was 17.6%. Although this tended to be higher in diabetic patients, there were no statistically significant differences between diabetic patients and controls. The incidence of H pylori infection in diabetic patients was 53.7% but no statistically significant difference was seen between diabetic patients and controls in the incidence of H pylori infection.
CONCLUSION: No significant differences could be seen between diabetic patients and controls in the incidence of RE and H pylori infection.

Abstract
Microaerobic bacteria were isolated from a baboon with pancreatic islet amyloidosis and hepatitis. Phenotypic and molecular analyses identified two distinct helicobacters. Analyses of 16S rRNA demonstrated "Helicobacter macacae" in the ileum and liver, and Helicobacter cinaedi in the colon. To the best of the authors' knowledge, this is the first report describing the isolation of enterohepatic Helicobacter species from a baboon.

Abstract
BACKGROUND The aim of this study was to investigate whether chronic infections with Helicobacter pylori and hepatitis B virus (HBV) might affect clinical outcomes in Chinese type 2 diabetic patients with advanced nephropathy. METHODS A prospective study of 97 type 2 diabetic patients with clinical proteinuria and renal insufficiency (median serum creatinine 200 micro mol/l). RESULTS During a median follow-up period of 2 years, 34 developed end-stage renal disease (ESRD), 28 had cardiovascular endpoints and 11 patients had died (seven men and four women), and 52.7% developed a combined endpoint. Female patients had longer disease duration, higher blood pressure, lower body weight but higher serum creatinine and spot urine albumin : creatinine ratio as well as lower haemoglobin than male patients. On logistic regression analysis, female gender (hazard ratio: 5.91, p = 0.02), negative H. pylori serology (8.39, p = 0.004), baseline serum creatinine (1.04, p = 0.001) and haemoglobin (1.86, p = 0.01) were independent predictors for ESRD. Systolic blood pressure (1.04, p = 0.003), prior treatment with angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists (3.41, p = 0.04) and positive hepatitis B surface antigen (4.88, p = 0.025) were independent predictors for cardiovascular endpoints. Female gender (7.89, p = 0.002) and baseline serum creatinine (1.05, p < 0.001) were independent predictors for combined death and cardio-renal endpoints. CONCLUSIONS In Chinese type 2 diabetic patients with clinical proteinuria renal insufficiency, there were high rates of death and cardio-renal outcomes. Female gender, low haemoglobin and negative H. pylori serology were important predictors for ESRD, whereas chronic HBV infection was associated with increased cardiovascular risks.
