A survey on Helicobacter pylori infection rate in Hainan Province and analysis of related risk factors. BMC Gastroenterol 2023; 23:338. [PMID: 37777740 PMCID: PMC10544117 DOI: 10.1186/s12876-023-02973-3] [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: 06/28/2023] [Accepted: 09/26/2023] [Indexed: 10/02/2023] Open
Abstract
OBJECTIVE The aim of this study was to understand the prevalence and potential risk factors of Helicobacter pylori (H. pylori) infection in Hainan Province, China. METHODS We conducted this study in 21 health service stations in 5 cities of Hainan Province from August 2022 to April 2023. We selected the various participants based on a stratified whole-group sampling method. The 14C-UBT was used to analyze H. pylori infection in 3632 participants. We also analyzed the possible relationship between variables and H. pylori infection based on chi-square test and multifactorial logistic regression. The model was evaluated by performing a Hosmer-Lemeshow goodness-of-fit test and plotting receiver operating characteristic(ROC) curves. RESULTS In total, the results of 3632 eligible participants (age: 14 to 93 years) were included in the analysis. The total prevalence of H. pylori infection in Hainan Province was approximately 38.7%. The prevalence of H. pylori infection was found to increase with age, stabilized in the age group of 45 to 64 years, but peaked in the age group of 65 years and older. In multifactorial analysis, the prevalence of H. pylori infection was positively associated with middle-aged adults (45-64 years), older adults (≥ 65 years), drinking, farmers, natural labor, routinely share utensils, have habit of frequent betel nut consumption, upper gastrointestinal symptoms, and family history of gastric cancer. The factors negatively associated with prevalence included family size ≤ 3, washing hands often before meals, frequent exercise, regular meals, and frequent consumption of fruits and vegetables. In addition, the Hosmer-Lemeshow test showed a good fit (χ2 = 12.983, P = 0.112) and the area under ROC was 0.631 (95%CI: 0.613 ~ 0.649). CONCLUSION The prevalence of H. pylori infection in Hainan Province was observed to be moderate and closely related to age, local socioeconomic conditions, hygienic status and dietary habits.

Abstract
Background Currently, the available evidence regarding the relationship between the lipid profile and Helicobacter pylori (H. pylori) infection is limited and conflicting. There is also a dearth of studies that have explored the possibility of sex-specific differences in the association between H. pylori infection and triglyceride levels. Methods We conducted a cross-sectional study involving 1,146 participants utilizing data from the National Health and Nutrition Examination Survey (NHANES) 1999-2000 conducted in the United States. A logistic regression model was employed to evaluate the association between H. pylori seropositivity and triglyceride levels. Subgroup analyses stratified by sex were conducted to explore sex-specific differences in this association. Results Serum triglyceride levels were significantly higher in H. pylori-seropositive participants than in H. pylori-seronegative participants. In the logistic regression analysis, there was a positive correlation between H. pylori seropositivity and triglyceride levels (OR=1.231; 95% CI, 1.016-1.491; P=0.033). In the subgroup analysis, the adjusted association between serum triglycerides and H. pylori seropositivity was significant in females (OR=1.732; 95% CI, 1.113-2.696; P=0.015) but not in males (OR=1.091; 95% CI, 0.698-1.705; P=0.704). Conclusion The association between high triglyceride levels and H. pylori infection is specific to the female population.

Du P, Zhang C, Wang A, Ma Z, Shen S, Li X. Association of Alcohol Drinking and Helicobacter pylori Infection : A Meta-analysis. J Clin Gastroenterol 2023; 57:269-277. [PMID: 34907920 DOI: 10.1097/mcg.0000000000001638] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Accepted: 10/14/2021] [Indexed: 12/10/2022]
Abstract
BACKGROUND The association between drinking and Helicobacter pylori infection was not clear in the literature. Owing to mixed and inconclusive results, a meta-analysis was conducted to summarize and clarify this association systematically. METHODS Based on a comprehensive search of PubMed, Embase, and Web of Science databases, studies investigating the association between drinking and H. pylori infection were retrieved. We evaluated the strength of this relationship using odds ratios (ORs) with 95% confidence intervals. Sensitivity analysis was also conducted. RESULTS A total of 24 individual studies were included in this meta-analysis. The risk of H. pylori infection was significantly lower in alcohol drinkers than nondrinkers (OR=0.83). People who drink wine (OR=0.90) or mixed types of alcoholic beverages (OR=0.78) had a lower risk of infection compared with those who drink beer. Among people aged 40 years or older, alcohol drinkers had a lower risk of H. pylori infection than nondrinkers (OR=0.68). Among people less than 40 years of age, alcohol drinking was not associated with H. pylori infection risk. Data showed that women were at a lower risk of H. pylori infection than men (OR=0.86). CONCLUSIONS This meta-analysis suggests that the risk of H. pylori infection among alcohol drinkers is lower than that of nondrinkers. Drinking wine and mixed types of alcohol are better at reducing H. pylori infection than drinking beer. Nonetheless, we discourage reducing H. pylori infection through drinking, which increases the risk of other diseases.

Abstract
Helicobacter pylori (Hp) is a prevalent organism infecting almost half the global population. It is a significant concern, given its associated risk of gastric cancer, which is the third leading cause of cancer death globally. Infection can be asymptomatic or present with dyspeptic symptoms. It may also present with alarm symptoms in the case of progression to cancer. Diagnosis can be achieved non-invasively (breath tests, stool studies, or serology) or invasively (rapid urease test, biopsy, or culture). Treatment involves acid suppression and regimens containing several antibiotics and is guided by resistance rates. Eradication is essential, as it lowers the risk of complications and progression to cancer. Follow-up after eradication is similarly important, as the risk of cancer progression remains. There have been many recent advances in both diagnosis and treatment of Hp. In particular, biosensors may be effective diagnostic tools, and nanotechnology, vaccines, and potassium-competitive acid blockers may prove effective in enhancing eradication rates.

Abstract
Helicobacter pylori infection is a significant risk factor for gastric cancer. The infection is acquired mainly in early childhood and is influenced by environmental factors, including socioeconomic status and sibling number. However, the impact of socioeconomic status and sibling number on Helicobacter pylori infection has not been well studied in Japan. We conducted a cross-sectional study to evaluate the impact of socioeconomic status, represented by education level, and sibling number on the prevalence of Helicobacter pylori infection among 3,423 non-cancer subjects who visited Aichi Cancer Center between 2005 and 2013. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) using a logistic regression model adjusted for potential confounding variables. Of the 3,423 subjects, 1,459 (42.6%) were Helicobacter pylori-positive. The prevalence of Helicobacter pylori infection linearly decreased with increasing socioeconomic status [ORs (95% CIs) of moderate and high socioeconomic status relative to low socioeconomic status of 0.67 (0.53-0.84) and 0.43 (0.34-0.54), respectively; P trend=9.7×10-17]. In contrast, the prevalence of Helicobacter pylori infection linearly increased with increasing sibling number [ORs (95% CIs) of SN 3-4 and ≥5 relative to sibling number ≤2 of 1.74 (1.47-2.06) and 2.54 (2.12-3.04), respectively; P trend=1.2×10-24]. This study showed that socioeconomic status and sibling number were significantly associated with the prevalence of Helicobacter pylori infection.

Association of Helicobacter Pylori With Development of Peptic Ulcer Disease Among Cirrhotic Patients: An Evidence From Population-Based Study. Cureus 2021; 13:e19315. [PMID: 34900489 PMCID: PMC8650630 DOI: 10.7759/cureus.19315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 10/28/2021] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) plays an important role in causing peptic ulcer disease (PUD) in the general population. However, the role of H. pylori in cirrhotic patients for causing PUD is obscure. There are various studies evaluating H. pylori association with PUD in cirrhotic patients, but the results have been controversial. We sought to analyze the association of H. pylori with the development of PUD in cirrhotic patients from the largest United States population-based database. METHODS We analyzed Nationwide Inpatient Sample (NIS) and Healthcare Cost and Utilization Project (HCUP) data from 2017. Adult hospitalizations due to cirrhosis were identified by previously validated ICD-10-CM codes. PUD and H. pylori were identified with the presence of ICD-10-CM codes in primary and secondary diagnosis fields, respectively. We performed weighted analyses using Chi-Square and paired Student's t-test to compare the groups. Multivariable survey logistic regression was performed to find an association of H. pylori with PUD in cirrhotic patients. RESULTS Our study showed that the prevalence of H. pylori infection was 2.2% in cirrhotic patients with PUD. In regression analysis, H. pylori was found to be associated with PUD in cirrhotic patients (OR 15.1; 95% CI: 13.9-16.4; p <0.001) and non-cirrhotic patients (OR 48.8; 95% CI: 47.5-50.1; p <0.001). In the studied population, H. pylori was more commonly seen in the age between 50 and 64 years (49.4% vs 44.1%; p <0.0001), male (63.4% vs 59.9%; p <0.0413), African American (16.3% vs 10.6%; p <0.0001), and Hispanic (26.2% vs 14.9%; p <0.0001). H. pylori is more likely to be associated with complicated PUD hospitalizations (51.2% vs 44.2%; p <0.0067). Alcoholism and smoking were more common in H. pylori group compared to those without (43.6% vs 35.8%; p <0.0001 and 33.7% vs 24.8% p <0.0001, respectively). Factors associated with increased odds of H. pylori infection include African American (OR 2.3, 95% CI: 1.5-3.6), Hispanic (OR 2.6, 95% CI: 1.7-4.0), and smoking (OR 1.5, 95% CI: 1.1-2.2). CONCLUSION H. pylori are associated with PUD and concurrent cirrhosis, although it is less prevalent than general population. African American, Hispanic, and smoking were independently associated with increased odds of H. pylori infection. Further studies are required to better understand the epidemiology and confirm our findings.

Abstract
BACKGROUND/AIMS The aim of this study was to assess the clinical and sociodemographic risk factors of Helicobacter pylori infection and antibiotic resistance in the eastern Black Sea region of Turkey. MATERIALS AND METHODS In total, 344 patients with dyspeptic symptoms who completed an extended questionnaire were enrolled in the study. Diagnosis of H. pylori infection was made by rapid urease test, histopathological investigation, and culture. Susceptibility of H. pylori strains was assessed by agar dilution (amoxicillin, tetracycline, metronidazole, levofloxacin) and E-test (clarithromycin) methods. RESULTS The H. pylori positivity rate was 40.4% (139/344). Logistic regression analysis indicated that age and the presence of duodenal ulcer were independent risk factors associated with H. pylori positivity (odds ratio (OR): 0.96, 95% CI: 0.93-0.99, p=0.013; OR: 5.42, 95% CI: 1.96-14.98, p=0.001, respectively). Of 104 H. pylori-positive cultures, 43 strains (41%) were susceptible to all antibiotics, whereas 61 (59%) were resistant to at least one antibiotic. H. pylori resistance rates were 34% for levofloxacin, 31.1% for metronidazole, 28.2% for clarithromycin, 2.9% for amoxicillin, and 1% for tetracycline. Logistic regression analysis indicated that previous use of clarithromycin was the only independent risk factor for H. pylori resistance (OR: 6.25, 95% CI: 1.59-24.52, p=0.009). CONCLUSION An understanding of the risk factors for H. pylori positivity and antibiotic resistance in an extended anamnesis may affect treatment choice and facilitate H. pylori eradication. In regions where antibiotic resistance rates are elevated, performing antibiotic susceptibility tests may lead to effective eradication treatment.

Abstract
The majority of studies concerning Helicobacter pylori (H. pylori) are oriented towards the implication of infection with H. pylori in processes that end in the formation of neoplasia, without assessing the impact of the bacterium in triggering acute gastroduodenal hemorrhagic episodes. The present study includes 166 patients with upper digestive hemorrhage, admitted to the ATI Clinic, the Gastroenterology Clinic or to the Surgery II Clinic of the County Emergency Clinical Hospital in Craiova, Romania between 2017 and 2019. All patients were monitored for evolution and received treatment according to current guidelines, and hemorrhagic lesions were biopsied. In the study group, 56.8% of the patients with upper gastrointestinal bleeding (UGIB) were positive for H. pylori and 43.2% were negative. In patients less than 50 years of age, non-steroidal anti-inflammatory drug (NSAID) use and H. pylori infection had a cumulative effect in causing bleeding lesions, but in patients older than 50 years of age, the use of NSAIDs was replaced by therapies with oral antiplatelet or anticoagulant agents. The need for hemostasis surgery was more common in patients who exhibited H. pylori-positive UGIB compared to H. pylori-negative (16 vs. 9.7%). In patients with H. pylori-positive hemorrhagic lesions, gastric resection was frequently required to obtain hemostasis. Persistence of H. pylori infection in patients with a history of gastric resection (4.1%) still predisposes to a hemorrhagic or neoplastic complication.

Abstract
Recently, the antibacterial properties of oestrogen and progestogen were discovered. The aim of this study was to find the cross-sectional association between oral contraceptive use and Helicobacter pylori seroprevalence. Data were obtained from the US National Health and Nutrition Examination Survey (NHANES). The H. pylori immunoglobulin G (IgG) enzyme-linked immunosorbent assays were used to categorise participants as seropositive or seronegative. The study population included 799 female participants who had information on H. pylori seroprevalence and all other covariates and had not been taking any medications (except oral contraceptives). The bivariate Rao–Scott chi-square test indicated a significant association between H. pylori seroprevalence and contraceptive use (P < 0.01). The variables of race, education, poverty income ratio, smoking, and blood lead and cadmium levels were also significantly associated with H. pylori seroprevalence (P < 0.01). Multiple logistic regression analysis of the age-adjusted model revealed that contraceptive users are 65% less likely of being H. pylori seropositive as compared to non-contraceptive users (odds ratio (OR): 0.35, 95% confidence interval (CI): 0.18–0.68). This association is stronger with the final multivariate model (OR: 0.46, 95% CI: 0.23–0.89). Conclusions: This finding reveals the potential protective effect of oral contraceptives against H. pylori infection and serves as a foundation study for further investigations.

Abstract
Objective We aimed to investigate the relationship of Helicobacter
pylori infection with alcohol and smoking. Methods We conducted a cross-sectional study among participants who underwent health
check-ups for H. pylori infection between January 2013 and
March 2017. We subsequently investigated the relationship of H.
pylori infection with alcohol and smoking. Results A total of 7169 participants were enrolled in this study. The overall
prevalence of H. pylori infection was 55.2%. Participants
with H. pylori infection were more likely to be older than
those without H. pylori infection. For male participants
with H. pylori infection, multivariable logistic regression
analysis indicated that both smoking (odds ratio (OR): 1.61; 95% confidence
interval (CI): 1.41–1.83) and alcohol consumption (OR: 1.30; 95% CI:
1.10–1.52) were independently positively associated with H.
pylori infection. For female participants, multivariable
logistic regression analysis indicated that both smoking (OR: 0.03; 95% CI:
0.02–0.07) and alcohol consumption (OR: 0.20; 95% CI: 0.12–0.33) were
inversely significantly associated with H. pylori infection
after adjustment for age. Conclusions Smoking and alcohol consumption were risk factors for male participants but
these were protective factors for female individuals with H.
pylori infection.

Abstract
Background: Peptic ulcer disease (PUD), which includes gastric and duodenal ulcers, is a common condition with symptoms including epigastric or abdominal pain. It is multifactorial, with physiological, demographic and environmental risk factors, some of which make it more prevalent in developing countries. Aims: This study aims to assess the symptoms of and risk factors for PUD among students at Jimma University, Jimma, Ethiopia. Methods: This institutional based cross-sectional study design used a self-administered questionnaire to collect data for analysis. This included logistic regression analysis, in which a p-value of <0.05 at 95% CI indicated statistical significance. Findings: Of the 240 respondents, 41.3% had symptoms indicative of PUD. Most students developed symptoms after enrolling at university and primarily managed them with medication. PUD-like symptoms were found to be associated with year of study, frequent Non-steroidal anti-inflammatory drugs(NSAIDs use, smoking, prolonged fasting and anxiety. Conclusions: PUD is highly prevalent in this setting. Therefore, the university may wish to raise awareness of PUD and aim to reduce anxiety among students.

Helicobacter pylori Infection, Virulence Genes' Distribution and Accompanying Clinical Outcomes: The West Africa Situation. BIOMED RESEARCH INTERNATIONAL 2019; 2019:7312908. [PMID: 31886245 PMCID: PMC6925786 DOI: 10.1155/2019/7312908] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 07/18/2019] [Accepted: 08/20/2019] [Indexed: 12/11/2022]
Abstract
Data on Helicobacter pylori (H. pylori) infection and virulence factors in countries across West Africa are scattered. This systematic review seeks to present an update on the status of H. pylori infection focusing on prevalence rate, distribution of virulent genes, and their link to clinical outcomes across countries in the western part of Africa. This information is expected to broaden the knowledge base of clinicians and researchers regarding H. pylori infection and associated virulence factors in West African countries. Search Method. A comprehensive search of the scientific literature in PubMed and ScienceDirect was conducted using the search terms including “Helicobacter pylori infection in West Africa”. Databases were sourced from January 1988 to December 2018. Results. Data on the incidence of H. pylori infection and related pathological factors were found for some countries, whereas others had no information on it. Smoking, alcohol, exposure to high levels of carcinogens and diet were reported to be involved in the pathogenesis of gastroduodenal diseases and gastric cancer. Besides the environmental factors and genetic characteristics, there are important characteristics of H. pylori such as the ability to infect, replicate, and persist in a host that have been associated with the pathogenesis of various gastroduodenal diseases. Concluding Remarks. This systematic search has provided information so far available on H. pylori virulence factors and clinical outcomes in West Africa. Accordingly, this piece has identified gaps in the body of knowledge highlighting the need for more studies to clarify the role of H. pylori virulence factors and associated clinical outcomes in the burden of this bacterial infection in West Africa, as data from these countries do not give the needed direct relation.

Abstract
BACKGROUND Studies have shown that ABO blood group antigens are associated with peptic ulcer disease (PUD). There are limited sources regarding the association of blood groups with PUD patients in Ethiopia. The aim of this study was to assess the association between ABO blood group distribution, non-steroidal anti-inflammatory drugs (NSAIDs), smoking, alcohol, coffee, and PUD at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia. METHODS A cross-sectional study was undertaken, and a total of 63 endoscopically confirmed PUD patients and 63 healthy controls were screened for ABO blood grouping using the standard slide agglutination reaction. Stool antigens were checked to determine Helicobacter pylori status of PUD patients. Chi-square and logistic regression were used for statistical analysis. RESULTS The ABO blood group distribution of PUD patients was 19.04% (12/63), 19.04% (12/63), 11.11% (7/63), 50.79% (32/63) for blood group A, B, AB, and O, respectively, while among control groups it was 25.39% (16/63), 23.80% (15/63), 12.69% (8/63), and 38.09% (24/63) for blood group A, B, AB, and O, respectively. 34.1% (22/63) of PUD patients had gastric ulcer and 65.9% (41/63) had duodenal ulcer. There was statistically a significant association between sex (p=0.001), use of NSAIDs (p=0.001), smoking cigarette (p=0.014), alcohol consumption (p=0.028), and PUD. CONCLUSION Although PUD trended as more prevalent among patients with blood group O than other blood group types their association was not statistically significant.

Abstract
BACKGROUND Helicobacter pylori (H.pylori) infections are prevalent and recognized as major cause of gastrointestinal diseases in Ethiopia. However, Studies conducted on the prevalence, risk factors and other clinical forms of H.pylori on different population and geographical areas are reporting conflicting results. Therefore, this review was conducted to estimate the pooled prevalence of H.pylori infections and associated factors in Ethiopia. METHODS PubMed, Embase, Google scholar, and Ethiopian Universities' repositories were searched following the Preferred Items for Systematic review and Meta-analysis (PRISMA) guideline. The quality of included studies was assessed using the Newcastle-Ottawa Scale in meta-analysis. Heterogeneity between studies was assessed using Cochrane Q test and I2 test statistics based on the random effects model. Comprehensive meta-analysis (CMA 2.0) and Review Manager (RevMan 5.3) were employed to compute the pooled prevalence and summary odds ratios of factors associated with of H.pylori infection. RESULTS Thirty seven studies with a total of 18,890 participants were eligible and included in the analysis. The overall pooled prevalence of H.pylori infection was 52.2% (95% CI: 45.8-58.6). In the subgroup analysis by region, the highest prevalence was found in Somalia (71%; 95% CI: 32.5-92.6) and the lowest prevalence was reported in Oromia (39.9%; 95% CI: 17.3-67.7). Absence of hand washing after toilet (OR = 1.8, 95% CI; 1.19-2.72), alcohol consumption (OR = 1.34, 95% CI; 1.03-1.74) and gastrointestinal (GI) symptoms (OR = 2.23, 95% CI; 1.59-3.14) were associated with H.pylori infection. The trend of H.pylori infection showed a decreasing pattern overtime from 1990 to 2017 in the meta-regression analysis. CONCLUSION The prevalence of H.pylori infection remains high; more than half of Ethiopians were infected. Although the trend of infection showed a decreasing pattern; appropriate use of eradication therapy, health education primarily to improve knowledge and awareness on the transmission dynamics of the bacteria, behavioral changes, adequate sanitation, population screening and diagnosis using multiple tests are required to reduce H.pylori infections. Recognizing the bacteria as a priority issue and designing gastric cancer screening policies are also recommended.

Abstract
Limited studies have reported the association between dietary patterns and the risk of Helicobacter pylori (H pylori) infection. The purpose of this study was to evaluate the relationship between dietary patterns and H pylori infection in a Chinese population ages from 45 to 59 years. We performed a cross-sectional examination of the associations between dietary patterns and H pylori infection in 3014 Chinese adults ages between 45 and 59 years from Hangzhou city, Zhejiang province, China. Dietary intake was assessed through a semi-quantitative food frequency questionnaire (FFQ). H pylori infection was diagnosed using the C-urea breath test. Multivariable logistic regression analyses were used to determine the associations between dietary patterns and the risk of H pylori infection. The prevalence of H pylori infection was 27.5%. Four major dietary patterns were identified by means of factor analysis: health-conscious, Western, grains-vegetables and high-salt patterns. After adjustment for the potential confounders, participants in the highest quartile of the "grains-vegetables" pattern scores had a lower odds ratio (OR) for H pylori infection (OR = 0.82; 95% confidence interval [CI]: 0.732-0.973; P = .04) than did those in the lowest quartile. Compared with those in the lowest quartile, participants in the highest quartile of the "high-salt" pattern scores had a greater OR for H pylori infection (OR = 1.13; 95%CI: 1.004-1.139; P = .048). Besides, no significant associations were found between the "health-conscious" and "Western" dietary patterns and the risk of H pylori infection.Our findings demonstrate that the "grains-vegetables" pattern is associated with a decreased risk, while "high-salt" pattern is associated with an increased risk of H pylori infection.

Abstract
Objectives Helicobacter pylori is a pathogenic bacterium that parasitizes the gastric mucous layer and the epithelial lining of the stomach causing duodenal ulcers, gastric ulcers and cardiovascular disease amongst others. This study aimed at establishing the epidemiologic profile of H. pylori infection in gastritis patients presenting at the Melong District Hospital. Results Blood, stool and epidemiological data collected from 500 patients were analyzed for the presence of H. pylori antibody in serum, antigen in stool and elucidation of risk factors captured in questionnaires. Of 500 blood samples, 217 (43.4%) were seropositive with male and female seroprevalences of 45.5% (61/134) and 42.6% (156/366) respectively. Similarly, 47.4% (237/500) samples tested positive for stool antigen with prevalences of 47.0% (63/134) for males and 47.5% (174/366) for females. The antigen prevalence was higher (53.2%; 118/222) in older patients (> 50 years) than in younger patients (42.8%; 119/278; P = 0.021). The antigen test had a higher (47.4%) prevalence than the antibody test (43.4%). Educational level, source of income, source of drinking water, age of patients, and alcohol consumption had positive associations with H. pylori infection. These results have clinical and epidemiological significance and call for intervention to mitigate the situation.

Abstract
This study aimed to explore the effects of active and latent Helicobacter pylori infection coupled with alcohol consumption on cytokine profiles and markers of oxidative balance in men seropositive for H. pylori CagA Ab.The 100 male subjects were divided into groups with active H. pylori infection and H. pylori CagA Ab coupled with chronic alcohol ingestion (group A, n = 38), latent H. pylori infection with H. pylori CagA Ab coupled with chronic alcohol ingestion (group B, n = 30), and latent H. pylori infection with H. pylori CagA Ab without chronic alcohol ingestion (group C, n = 32).No differences in serum levels of CRP, IL-10, ADP, E-selectin, MDA, or SOD were detected between the 3 groups or between any 2 groups (all P > .05). The serum IL-6 and TNF-α concentrations in groups A and B were significantly lower than those in group C (P = .004, P = .005, P = .009, and P = .023). However, there were no differences in serum IL-6 and TNF-α between group A and group B (all P > .05).In conclusion, active or latent H. pylori infection coupled with chronic alcohol ingestion may decrease certain cytokines, that is, IL-6 and TNF-α, in men with H. pylori CagA Ab seropositivity. However, there was no difference in the detected cytokine profile between active and latent H. pylori infection coupled with chronic alcohol ingestion, and no changes were detected in markers of oxidative balance in men with H. pylori CagA Ab.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is the most common chronic bacterial infection in the world. It can result in various upper gastroduodenal diseases. The prevalence varies among countries, population groups within the same country and testing methods. The aim of the study was to determine feco-prevalence and risk factors of H.pylori infection among symptomatic patients in Amhara region, Northeast Ethiopia. METHODS A cross sectional study was conducted in a total of 342 new consecutive outpatients with upper abdominal complaints at Dessie Referral Hospital from May to July, 2016. A structured questionnaire was used to collect the socio-demographic, lifestyle and environmental data. Stool samples were used to detect H. pylori specific antigen. Blood samples were assessed for anti-H. pylori IgG and ABO blood types. SPSS version 20.0 statistical software package was used for data analysis. Chi-square test and logistic regression were used in the analysis and P-value ≤0.05 was considered as statistically significant. RESULTS H. pylori stool antigen and serum anti-H.pylori IgG detection rate was 30.4 and 60.5% respectively with kappa measure of agreement of 0.271. Antigen detection was significantly associated with family size (> 3) [AOR = 1.83, 95% CI: 1.10-3.05, p = 0.02], more persons (> 3) sharing the same bed room in the household [AOR = 2.91, 95% CI: 1.39-6.11, p = 0.005], alcohol consumption (> once a week) [AOR = 2.70, 95% CI: 1.49-4.89, p = 0.001] and individuals' blood type: group O [AOR = 8.93, 95%CI: 1.79-44.48, p = 0.008] and group A [AOR = 5.53, 95%CI: 1.08-28.36, p = 0.040]. Gender, age, marital status, occupation, educational level, residence, smoking as well as coffee, tea, fruits and vegetables consumption were not statistically associated with H. pylori antigen detection (p > 0.05). CONCLUSION The overall H. pylori stool antigen and anti-H. pylori IgG detection rate was 30.4 and 60.5%, respectively. The test agreement was not strongly convincing and needs further evaluation. Alcohol consumption, overcrowding and ABO blood group were significantly associated with H. pylori antigen detection.

Abstract
BACKGROUND Incidence of gastric cancer is the highest in Eastern Asia. Multiple modifiable lifestyle factors have been identified as risk factors for gastric cancer. However, their aggregated effect on the risk of gastric cancer has not been examined among populations with high prevalence of Helicobacter pylori. METHODS A study was conducted to examine the association between multiple lifestyle factors together and the risk of developing gastric adenocarcinoma in the Singapore Chinese Health Study, a prospective cohort of 63 257 men and women between 45 and 74 years enroled during 1993-1998. Composite score of cigarette smoking, alcohol consumption, obesity, dietary pattern, and sodium intake at baseline was assessed with hazard ratio (HR) and 95% confidence interval (CI) of gastric adenocarcinoma using Cox regression method. RESULTS Higher healthy composite lifestyle scores were significantly associated with reduced risk of gastric adenocarcinoma in a dose-dependent manner. Hazard ratios (95% CIs) for total, cardia, and non-cardia gastric adenocarcinoma for the highest (score 5) vs lowest composite score (score 0/1/2) were 0.42 (0.31-0.57), 0.22 (0.10-0.47), and 0.55 (0.39-0.78), respectively (all Ptrend<0.001). These lifestyles together accounted for 48% of total gastric adenocarcinoma cases in the study population. The inverse association was observed in both genders, and remained after exclusion of first 5 years of follow-up. CONCLUSIONS The inverse association between the aggregated healthy lifestyle factors and the risk of gastric adenocarcinoma is in dose-dependent manner in this highly H. pylori-exposed population. These lifestyle factors together may account for up to half of disease burden in this study population.

World J Gastroenterol 2016; 22:7536-7558.

Abstract
AIM To determine the impact of selected well defined Helicobacter pylori (H. pylori) antigens on gastric barrier cell turnover.
METHODS In this study, using two cellular models of gastric epithelial cells and fibroblasts, we have focused on exploring the effects of well defined H. pylori soluble components such as glycine acid extract antigenic complex (GE), subunit A of urease (UreA), cytotoxin associated gene A protein (CagA) and lipopolysaccharide (LPS) on cell turnover by comparing the wound healing capacity of the cells in terms of their proliferative and metabolic activity as well as cell cycle distribution. Toxic effects of H. pylori components have been assessed in an association with damage to cell nuclei and inhibition of signal transducer and activator of transcription 3 (STAT3) phosphorylation.
RESULTS We showed that H. pylori GE, CagA and UreA promoted regeneration of epithelial cells and fibroblasts, which is necessary for effective tissue healing. However, in vivo increased proliferative activity of these cells may constitute an increased risk of gastric neoplasia. In contrast, H. pylori LPS showed a dose-dependent influence on the process of wound healing. At a low concentration (1 ng/mL) H. pylori LPS accelerated of healing epithelial cells, which was linked to significantly enhanced cell proliferation and MTT reduction as well as lack of alterations in cell cycle and downregulation of epidermal growth factor (EGF) production as well as cell nuclei destruction. By comparison, H. pylori LPS at a high concentration (25 ng/mL) inhibited the process of wound repair, which was related to diminished proliferative activity of the cells, cell cycle arrest, destruction of cell nuclei and downregulation of the EGF/STAT3 signalling pathway.
CONCLUSION In vivo H. pylori LPS driven effects might lead to the maintenance of chronic inflammatory response and pathological disorders on the level of the gastric mucosal barrier.

Abstract
Previous studies indicated that food consumption was associated with Helicobacter pylori infection, but no study has yet investigated the association between Helicobacter pylori infection and dietary patterns. The aim of this study was to evaluate the associations between Helicobacter pylori infection and dietary patterns in Tianjin, China. The final cross-sectional study population comprised 10407 participants. Dietary consumption of participants was assessed via food frequency questionnaire. Factor analysis was used to identify dietary patterns, and Helicobacter pylori infection status was diagnosis by H. pylori urease Immunogold Testing kit. Participants in the highest quartile of the high-carbohydrate/sweet pattern showed a multivariable-adjusted OR (95% CI) of 1.65 (1.27–2.17) for the prevalence of H. pylori infection compared with those in the lowest quartile. The multiple adjusted OR for scores of the extreme quartile of high-protein/cholesterol pattern was 0.75 (95% CI, 0.57–0.98). This study demonstrated that a diet rich in carbohydrates and sweets was positively associated with the prevalence of H. pylori infection; interestingly, a diet characterized by high intake of animal offal, animal blood, fish, seafood, and poultry was associated with a reduction of prevalence of H. pylori infection.

Abstract
BACKGROUND Early diagnosis of gallbladder cancer (GBC) can remarkably improve the prognosis of patients. This study aimed to develop a nomogram for individualized diagnosis of stage I-II GBC in chronic cholecystitis patients with gallbladder wall thickening. METHODS The nomogram was developed using logistic regression analyses based on a retrospective cohort consisting of 89 consecutive patients with stage I-II GBC and 1240 patients with gallbladder wall thickening treated at one biliary surgery center in Shanghai between January 2009 and December 2011. The accuracy of the nomogram was validated by discrimination, calibration and a prospective cohort treated at another center between January 2012 and December 2014 (n=928). RESULTS Factors included in the nomogram were advanced age, hazardous alcohol consumption, long-standing diagnosed gallstones, atrophic gallbladder, gallbladder wall calcification, intraluminal polypoid lesion, higher wall thickness ratio and mucosal line disruption. The nomogram had concordance indices of 0.889 and 0.856 for the two cohorts, respectively. Internal and external calibration curves fitted well. The area under the receiver-operating characteristic curves of the nomogram was higher than that of multidetector row computed tomography in diagnosis of stage I-II GBC (P<0.001). CONCLUSION The proposed nomogram improves individualized diagnosis of stage I-II GBC in chronic cholecystitis patients with gallbladder wall thickening, especially for those the imaging features alone do not allow to confirm the diagnosis.

Abstract
The aim of this study was to evaluate the effect of Helicobacter pylori (H pylori) cytotoxin-associated gene A (CagA) coupled with chronic alcohol ingestion on cytokine profiles.A total of 215 male subjects were divided into the following 4 groups: 130 alcohol H pylori CagA-negative consumers (CagA-) (group A), 50 alcohol H pylori CagA-positive consumers (CagA+) (group B), 24 nonalcohol H pylori CagA-negative consumers (group C), and 11 nonalcohol H pylori CagA-positive consumers (group D). The serum CagA, C-reactive protein (CRP), interleukin (IL)-6, IL-10, E-selectin, adiponectin (ADP), and tumor necrosis factor-α (TNF-α) levels were measured through enzyme-linked immunosorbent assays (ELISAs).After adjusting for age and mean alcohol drinking history, a multivariable linear regression analysis revealed that the mean daily alcohol consumption, IL-6, TNF-α, and ADP levels were significantly increased with increases in the serum CagA concentrations (P = 0.008, P = 0.000, P = 0.000, and P = 0.006, respectively). The serum IL-6 and IL-10 levels of group A were significantly lower than those of group B (all P = 0.000). Furthermore, the serum IL-6 and IL-10 levels of groups A and C were significantly lower than those of group D (all P = 0.000), and the serum IL-6 and IL-10 levels of group C were significantly lower than those of group B (all P = 0.000). The serum ADP and E-selectin levels of groups B and D were significantly higher than those of group A (P = 0.000). The serum ADP levels of group B were significantly higher than those of group C (P = 0.000), and the serum ADP and E-selectin levels of group C were significantly lower than those of group D (P = 0.000 and P = 0.005, respectively). Finally, the serum TNF-α levels of groups B, C, and D were significantly higher than those of group A (all P = 0.000), and the serum TNF-α levels of group C were significantly higher than those of group D (P = 0.005).In conclusion, H pylori CagA may result in significantly higher levels of several inflammatory markers in both alcohol consumers and nonalcohol consumers. However, chronic alcohol ingestion coupled with H pylori CagA positivity does not result in significant changes in cytokine profiles.

Abstract
Background Alcohol intake has been suggested to have an impact on the development of many chronic diseases. How alcohol intake may modulate risk of Helicobacter pylori (H. pylori) infection, however, remains a subject open for investigation. A dose-response meta-analysis was performed of epidemiological studies to better quantify this relationship. Materials and methods Twelve observational articles were identified. The summary odds ratio (OR) and confidence intervals (CI) were calculated for alcohol drinkers vs non-drinkers. The summary OR estimates were obtained using the random-effects model and dose-response meta-analysis. Sub-group and sensitivity analysis were also conducted. Results The summary OR was 0.78 (95% CI = 0.69-0.89). The dose-response analysis demonstrated that for drinkers of 10, 15, 30, 60 and 96 g/day alcohol intake, the estimated ORs were 0.80 (95% CI = 0.76-0.85), 0.79 (95% CI = 0.75-0.84), 0.83 (95% CI = 0.78-0.87), 0.85 (95% CI = 0.78-0.93) and 0.87 (95% CI = 0.70-1.06), respectively, compared to non-drinkers. The inverse relationship between alcohol intake and H. pylori infection was consistent, regardless of sex, age, geographic areas, detection methods or beverage types. CONCLUSION Evidence from these observational studies suggests that moderate alcohol intake is associated with a reduction in H. pylori infection of ∼ 22% and may facilitate elimination of H. pylori.

Abstract
AIM: To investigate the influence of proton pump inhibitors (PPIs) exposure on the diagnosis of Helicobacter pylori (H. pylori) gastritis and intestinal metaplasia.
METHODS: Chronic PPI use is associated with masking of H. pylori infection. Patients with H. pylori infection are predisposed to gastric and duodenal ulcers, and long-term infection with this organism has been associated with gastric mucosal atrophy and serious long-term complications, such as gastric lymphoma and adenocarcinoma. Three hundred patients diagnosed with gastritis between January 2008 and April 2010 were included in our study. The computerized medical database of these patients was reviewed retrospectively in order to assess whether the type of gastritis diagnosed (H. pylori vs non-H. pylori gastritis) is influenced by PPI exposure. H. pylori density was graded as low, if corresponding to mild density following the Updated Sydney System, or high, if corresponding to moderate or severe densities in the Updated Sydney System.
RESULTS: Patients were equally distributed between males and females with a median age at the time of diagnosis of 50 years old (range: 20-87). The histological types of gastritis were classified as H. pylori gastritis (n = 156, 52%) and non-H. pylori gastritis (n = 144, 48%). All patients with non-H. pylori gastritis had inactive chronic gastritis. Patients with no previous PPI exposure were more likely to be diagnosed with H. pylori gastritis than those with previous PPI exposure (71% vs 34.2%, P < 0.001). Intestinal metaplasia was more likely to be detected in the latter patients (1.4% vs 6.5%, P = 0.023). Multivariate analysis has also demonstrated that in the presence of previous PPI exposure (OR = 0.217, 95%CI: 0.123-0.385), GERD (OR = 0.317, 95%CI: 0.132-0.763, P = 0.01), alcohol intake (OR = 0.396, 95%CI: 0.195-0.804, P = 0.01), the detection of H. pylori was less likely. Chronic use of PPIs may mask H. pylori infections promoting the diagnosis of non-H. pylori gastritis and leads to a significant drop in H. pylori densities and to an increased risk of intestinal metaplasia.
CONCLUSION: The use of PPIs masks H. pylori infection, promotes the diagnosis of non-H. pylori inactive chronic gastritis diagnosis, and increases the incidence of intestinal metaplasia.

Abstract
Background The epidemiology of Helicobacter pylori (H. pylori) infection in waste pickers had not been previously studied. This study aims to determine the association of H. pylori seropositivity and waste picking activity; and to determine socio-demographic, clinical, work, and behavioral characteristics associated with H. pylori seropositivity in waste pickers. Methods Through a case-control study design, we examined 90 waste pickers and 90 age- and gender-matched control subjects for the presence of anti-H. pylori IgG antibodies using enzyme-linked immunoassays. Seroprevalence association with socio-demographic, clinical, work and behavioral characteristics of the waste pickers were also investigated. Results Antibodies to H. pylori were found in 60 (66.7%) of the 90 waste pickers and in 51 (56.7%) of the 90 controls (P = 0.16). Stratification by age showed that waste pickers aged 14 -30 years old had significantly higher frequency of H. pylori infection than controls of the same age group (56.5% versus 35.6%, respectively; P = 0.04). The seroprevalence of H. pylori infection was not influenced by gender, age, educational level, socioeconomic status, residence, or housing conditions of waste pickers. The presence of underlying diseases and the frequency of gastritis were similar among H. pylori positive and H. pylori negative waste pickers. Logistic regression analysis showed that the duration (years) in the waste picking activity was positively associated with H. pylori exposure (OR = 2.76; 95% CI: 1.22 - 6.25; P = 0.01). In contrast, consumption of alcohol was negatively associated with H. pylori exposure (OR = 0.27; 95% CI: 0.09 - 0.78; P = 0.01). Other work or behavioral characteristics of waste pickers including washing hands before eating, eating from the garbage, animal contacts, consumption of unpasteurized milk, unwashed raw vegetables, fruits, or untreated water, and contact with soil were not associated with H. pylori exposure. Conclusions This is the first report on the seroprevalence of H. pylori infection among waste pickers and the factors contributing to such exposure. Results warrant for further research on the potential role of contact with garbage for H. pylori infection.

Abstract
BACKGROUND The association between soft drink (SD) consumption and Helicobacter pylori infection remains unclear. AIM To examine the relationship between SD consumption and H. pylori infection. METHODS A prospective study included individuals who were referred for an upper gastrointestinal endoscopic examination because chronic dyspepsia within a period of 1 year. In addition to determining daily SD consumption and the risk factors for H. pylori infection by asking all study participants to complete a standard questionnaire about their diet, daily eating and drinking habits, and their lifestyle before undergoing the endoscopic examination. H. pylori infection was established by a positive result of the rapid urease test and histology. RESULTS Of the 312 individuals who were referred for the endoscopic examination because chronic dyspepsia, 269 met the inclusion criteria. H. pylori infection was found in 164 (61%) of the 269 study participants, and, of these, 104/164 individuals were SD consumers with H. pylori infection versus 24/105 individuals without H. pylori infection (63 vs. 23%, respectively, P < 0.001). The results of the multiple logistic regression analysis showed that SD consumption (odds ratio = 4.0; 95 % confidence interval = 3.19–5.82,P < 0.001), was associated with H. pylori infection. CONCLUSION SD consumption is associated with H. pylori infection in individuals with chronic dyspepsia.

Abstract
Whether the exceptionally low prevalence of Helicobacter pylori (HP) infection reported among Malays is also present among aborigines (the Orang Asli) living in northeastern Peninsular Malaysia is unknown. We studied asymptomatic Orang Asli from settlements situated 210 km from the city of Kota Bharu. The HP infection status was confirmed by a validated serology test. Nineteen percent of 480 Orang Asli tested positive for HP infection. The prevalence was 40.6% in the birth cohort of the 1940s and declined steadily in later cohorts to under 10% among 12-30 year olds. This may be related to the phases of relocation from the jungles into resettlement camps and ultimately into designated villages near rivers. The low prevalence pattern after the 1970s was probably partly a result of improvement in sanitation and hygiene practice in these villages but other unidentified factors may also be operating.
