Abstract
OBJECTIVE Description of the changing patterns of antibiotic resistance in Helicobacter pylori infection in the Netherlands. DESIGN Retrospective database study using the Dutch infectious disease surveillance information system-antibiotic resistance (ISIS-AR). METHOD In the ISIS-AR database antibiotic resistance data are reported by 46 microbiologic laboratories in the Netherlands. For the present study, data from 16 centres were used with a 10 year period of reporting H. pylori resistance data, from 1 January 2010 till 1 January 2020, for amoxycillin, levofloxacin, claritrhromycin, tetracyclin and metronidazole. RESULTS In 2019 Antimicrobial resistance rates in the Netherlands were 1% for tetracycline, 5% for amoxycillin, 23%% for levofloxacin, 46% for metronidazole and 47% for clarithromycin. The combined resistance rate for clarithromycin and metronidazole was 29%. Significantly higher resistance rates were found in female patients for amoxycillin (8% vs 1%), clarithromycin (53% vs 38%) and metronidazole (52% vs 38%). From 2010 to 2019, a significant rise in resistance rates was found for amoxycillin (0% - 5%), clarithromycin (7% - 40%), metronidazole (14% - 45%) and for the clarithromycin and metronidazole combination (2% - 29%). CONCLUSION There was an important rise in antibiotic resistance rates in H. pylori in the Netherlands. For optimal H. pylori treatment bismuth-based therapies should become available again in the Netherlands. Treatment of H. pylori should be based on the individual antibiotic resistance profile and be in concordance with the principles of antibiotic stewardship. Guidelines for treatment of H. pylori in the Netherlands should be adapted and have a better correlation with International guidelines and best practices.

Abstract
BACKGROUND/AIMS Helicobacter pylori infection is presumably associated with iron deficiency and iron deficiency anemia (IDA). This study aimed to evaluate the relationship between H. pylori infection and the decline in iron stores in non-elderly adults during their health check-ups. METHODS We identified a total of 1,069 subjects who were tested for iron, ferritin, and total iron-binding capacity during their health check-ups, from January 2016 to May 2017. Of these, subjects who underwent endoscopy via rapid urease test and those aged 65 years or below were finally enrolled. RESULTS Overall, 281 subjects were enrolled, and 187 patients (66.5%) tested positive for H. pylori. The mean age was 36.1 years (range, 22 to 65), and 176 subjects (62.6%) were male. The mean levels of hemoglobin (14.1 ± 1.7 g/dL vs. 14.6 ± 1.4 g/dL, p = 0.019) and ferritin (121.7 ± 106.9 ng/mL vs. 151.8 ± 107.8 ng/mL, p = 0.027) in the H. pylori-positive group were significantly lower than those in the H. pylori-negative group. Iron deficiency (ferritin < 30 ng/mL) was more common in patients with H. pylori infection (p = 0.002). There was no significant difference in anemia (hemoglobin < 13 g/dL in men, < 12 g/dL in women) or IDA (anemia, ferritin < 10 ng/mL, and transferrin saturation < 16%) with H. pylori. Logistic regression analysis demonstrated that female sex (odds ratio, 197.559; 95% confidence interval, 26.461 to 1,475.015) and H. pylori infection (odds ratio, 3.033; 95% confidence interval, 1.216 to 7.567) were factors associated with iron deficiency. CONCLUSION H. pylori infection is associated with iron deficiency, suggesting a decline in iron stores among infected non-elderly adults.

Abstract
BACKGROUND & AIMS Helicobacter pylori infection is the primary known risk factor for gastric cancer. Despite the global decline in H. pylori prevalence, this infection remains a major public health concern in developing areas, including Latin America. Our study aimed to determine H. pylori seroprevalence and identified its determinants among Hispanics/Latinos living in the United States (U.S.). METHODS The Hispanic Community Health Study/Study of Latinos (HCHS/SOL) is a population-based sample of self-identified Hispanics/Latinos (n = 16,144) in four U.S. communities, aged 18 to 74 years, recruited from randomly selected households using a stratified two-stage area probability sample design based on sampling households within sampled census block groups weighted for differential response rates. Anti-H. pylori immunoglobulin G antibodies were measured by an enzyme-linked immunosorbent assay using plasma samples. We calculated adjusted seroprevalence (i.e., predicted margins) from multivariable logistic regression models. RESULTS The overall weighted H. pylori seroprevalence was 57% among HCHS/SOL participants, with 38% and 62% seropositivity among U.S.-born and non-U.S.-born individuals, respectively. Age-adjusted prevalence varied by self-reported Hispanic/Latino background, ranging from 47% in Puerto Rican to 72% in Central American backgrounds. Adjusted H. pylori seroprevalence was higher in the following groups: older age, male sex, lower education, non-U.S. born status, smoking, greater number of missing teeth, fewer doctor visits, lower ferritin level, and hepatitis A seropositivity. CONCLUSIONS H. pylori seroprevalence in Hispanics/Latinos remains high and differed significantly by Hispanic/Latino background. H. pylori seropositivity is strongly associated with poor socioeconomic conditions. These findings highlight the ongoing importance of this bacterial infection in the U.S.

Abstract
BACKGROUND Synthesised data on the prevalence of, and factors associated with, paediatric Helicobacter pylori infection at the global level remain scarce. We aimed to estimate the global prevalence of H pylori infection and its associated factors in children and adolescents. METHODS In this systematic review and meta-analysis, we searched PubMed, Embase, MEDLINE, and Scopus for observational population-based studies published between database inception and Oct 25, 2021, without language or geographical restrictions. We included studies that reported the prevalence of H pylori infection in children aged 18 years or younger. Records were screened and data were extracted using a standardised extraction form. We estimated the worldwide prevalence of H pylori infection in children (our main outcome) using multilevel mixed-effects meta-regression and then stratified prevalence by diagnostic method (serology vs urea breath tests or stool antigen tests). We analysed the significance of associated factors using a random-effects meta-analysis. This study is registered in PROSPERO, CRD42020209717. FINDINGS We identified 3181 records, of which 198 articles with 632 data points from 152 650 children were included. The overall global prevalence of H pylori infection in children was 32·3% (95% CI 27·3-37·8), which varied by diagnostic test (28·6% [23·0-35·0] for serology vs 35·9% [29·2-43·2] for urea breath tests or stool antigen tests). Regardless of diagnostic test, the prevalence of H pylori infection was significantly higher in low-income and middle-income countries than in high-income countries (43·2% [36·5-50·2] vs 21·7% [16·9-27·4]; p<0·0001) and in older children than in younger children (41·6% [35·6-47·8] in 13-18-year-olds vs 33·9% [28·6-39·7] in 7-12-year-olds vs 26·0% [21·4-31·0] in 0-6-year-olds; p<0·0001). Paediatric H pylori infection was significantly associated with lower economic status (odds ratio [OR] 1·63 [95% CI 1·46-1·82]), more siblings or children (1·84 [1·44-2·36]), room sharing (1·89 [1·49-2·40]), no access to a sewage system (1·60 [1·22-2·10]), having a mother infected with H pylori (3·31 [2·21-4·98]), having a sibling or siblings infected with H pylori (3·33 [1·53-7·26]), drinking unboiled or non-treated water (1·52 [1·32-1·76]), and older age (OR per year 1·27 [1·15-1·40]). INTERPRETATION H pylori infection is still highly prevalent in children and adolescents globally. Our findings can help to guide further research and the development and implementation of preventive and therapeutic measures to reduce H pylori infection in children. FUNDING None.

Abstract
Since numerous studies have stated that there may be a relationship between Helicobacter pylori infection and nonalcoholic fatty liver disease, and because of the high prevalence of both conditions worldwide, this study investigated the risk of non-alcoholic fatty liver disease in patients infected with H. pylori. Following a systematic review of PubMed, Scopus, Web of Science and Embase, and a search in Google Scholar using MeSH terms such as H. pylori and non-alcoholic fatty liver disease, the relevant papers up to November 2020 were reviewed. All cohort, case-control, and cross-sectional studies that examined the risk of developing non-alcoholic fatty liver disease in patients infected with H. pylori entered this study. A meta-analysis was conducted in STATA 11. This systematic review examined 22 papers with 117 117 participants (33 711 patients infected with H. pylori and 83 406 participants as control) and 20 studies were subjected to meta-analysis The results indicated a 22% to 27% increase in the risk of developing non-alcoholic fatty liver disease in patients infected with H. pylori (crude odds ratio: 1.27, 95% CI: 1.17-1.33; and adjusted odds ratio: 1.22, 95% CI: 1.09-1.35). According to the subgroup analysis, the study region, sample size, and the method of diagnosing H. pylori were the factors contributing to the high heterogeneity. The meta-analysis revealed the increased risk of developing non-alcoholic fatty liver disease in patients infected with H. pylori. This indicates that H. pylori is a serious risk factor in patients susceptible to NAFLD.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is known to prevent the occurrence of gastroesophageal reflux disease (GERD) by inducing gastric mucosal atrophy. However, little is known about the relationship between atrophic gastritis (AG) and GERD.
AIM To confirm the inverse correlation between AG and the occurrence and severity of GERD.
METHODS Individuals receiving health checkups who underwent upper gastrointestinal endoscopy at Seoul National University Healthcare System Gangnam Center were included. The grade of reflux esophagitis was evaluated according to the Los Angeles classification. Endoscopic AG (EAG) was categorized into six grades. Serologic AG (SAG) was defined as pepsinogen I ≤ 70 ng/mL and pepsinogen I/II ratio ≤ 3.0. The association between the extent of EAG and SAG and the occurrence and severity of GERD was evaluated using multivariate logistic regression analysis.
RESULTS In total, 4684 individuals with GERD were compared with 21901 healthy controls. In multivariate logistic regression analysis, advanced age, male sex, body mass index > 23 kg/m2, presence of metabolic syndrome, current smoking, and alcohol consumption were associated with an increased risk of GERD. Seropositivity for H. pylori immunoglobulin G antibodies was associated with a decreased risk of GERD. There was an inverse correlation between the extent of EAG and occurrence of GERD: Odds ratio (OR), 1.01 [95% confidence interval (CI): 0.90-1.14] in C1, 0.87 (0.78-0.97) in C2, 0.71 (0.62-0.80) in C3, 0.52 (0.44-0.61) in O1, 0.37 (0.29-0.48) in O2, and 0.28 (0.18-0.43) in O3. Additionally, the extent of EAG showed an inverse correlation with the severity of GERD. The presence of SAG was correlated with a reduced risk of GERD (OR = 0.49, 95%CI: 0.28-0.87, P = 0.014).
CONCLUSION The extent of EAG and SAG exhibited strong inverse relationships with the occurrence and severity of GERD. AG followed by H. pylori infection may be independently protect against GERD.

Abstract
Objective: To explore the time trends of H. pylori infection and related drug use in patients with peptic ulcer bleeding (PUB) in recent ten years. Methods: PUB patients in Peking University Third Hospital from 2010 to 2019 were included. Time trends of H. pylori infection, related drugs (non-steroidal anti-inflammatory drugs, aspirin, antiplatelet drugs, anticoagulant drugs, glucocorticoids) use and non-H. pylori-non-drug ulcer in PUB patients were analyzed. Results: A total of 1 140 PUB patients were included from 2010 to 2019 (including 925 males and 215 females). The age M(Q1,Q3)was 53.5 (33.0, 66.0) years, with 833 patients <65 years old. The positive rates of H. pylori were 79.3%, 75.7%, 73.1%, 71.6%, 77.0%, 70.4%, 69.7%, 63.1%, 51.4%, 50.9%, respectively, showing a decreasing trend (χ²=32.386, P<0.001), and the decreasing trends were significant in different ulcer location, age and gender subgroups(all P<0.05). The proportions of PUB patients using at least one of the above drugs were 23.1%, 28.6%, 34.0%, 39.5%, 33.8%, 35.9%, 28.7%, 39.8%, 40.9%, 41.8%, respectively, showing an increasing trend (χ²=6.857, P=0.009), and the proportions of patients with antiplatelet drugs and anticoagulant drugs history showed increasing trends. The proportions of non-H. pylori-non-drug patients were 12.3%, 22.1%, 14.6%, 13.2%, 7.7%, 13.0%, 16.9%, 18.7%, 22.6% and 20.9%, respectively, showing an increasing trend (χ²=4.808, P=0.028). Accordingly, the proportions of elderly (≥65 years old) patients (χ²=4.608, P=0.032) and large ulcer (≥2 cm) patients (χ²=8.173, P=0.004) showed increasing trends. Conclusion: In the last decade, the positive rate of H. pylori in PUB patients showed a decreasing trend, while the proportions of patients with antiplatelet drugs and anticoagulant drugs history and the proportion of non-H. pylori-non-drug patients showed increasing trends.

Abstract
BACKGROUND AND STUDY AIM Immunohistochemistry is one of the superior methods and is regarded as the gold standard for the detection of Helicobacter pylori. We aimed to detect the presence of Helicobacter pylori in gastric biopsies among patients at the Muhimbili National Hospital from January 2012 to December 2016. Also, we determined the predictors of Helicobacter pylori infection. PATIENTS AND METHODS Retrospectively, we retrieved the tissue blocks of gastric biopsies at the Central Pathology Laboratory of the patients with different gastric pathologies at the Muhimbili National Hospital from January 2012 to December 2016. Helicobacter pylori were detected using anti-Helicobacter pylori polyclonal antibodies. Binary logistic regression analysis was done to determine the predictors of Helicobacter pylori infection. A two-tailed p < 0.05 was considered significant. RESULTS The prevalence of detection of Helicobacter pylori was 37.1% (63/170) using immunohistochemistry compared to 32.4% (55/170) using histology. Peptic ulcer disease, the absence of gastric cancer, and chronic gastritis were the predictors of Helicobacter pylori infection in our study (AOR = 0.2, 95% CI = 0.06-0.70, p = 0.011, AOR = 3.23, 95% CI = 1.02-10.29, p = 0.047, AOR = 0.32, 95% CI = 0.12-0.87, p = 0.025, respectively). CONCLUSION In this study, Helicobacter pylori infection was associated with the presence of peptic ulcer disease, chronic gastritis, and the absence of gastric cancer. The rate of detection of Helicobacter pylori infection was higher in tissue blocks of elderly patients than in those of young patients. Also, gastric cancer was more prevalent in old female patients.

Abstract
Stomach cancer is the third leading cause of cancer death globally. Helicobacter pylori plays a role in the healthy human gut, but is also associated with multiple chronic diseases, including stomach cancer. Though H. pylori prevalence is declining in parts of the world, it remains high among certain populations. In Arizona, stomach cancer rates are 3-4 times higher among the Navajo Nation population as compared with the non-Hispanic white population. This pilot project assessed adult Diné (Navajo) individuals' understanding and awareness regarding H. pylori infection and stomach cancer. Focus groups were held in three Diné communities. Data were analyzed thematically using a multi-investigator consensus approach. Participants had limited knowledge of H. pylori infection and stomach cancer and perceived local medical providers as also having limited knowledge on these conditions. Participants described poor health care experiences, structural inequalities, and environmental concerns and associated these with H. pylori infection and stomach cancer. This study highlights the need for additional research and education on current knowledge and perceptions of stomach cancer and H. pylori infections in Navajo Nation.

Abstract
OBJECTIVE To evaluate the general population's awareness of and attitudes toward Helicobacter pylori (HP) screening and health behaviours. DESIGN Cross-sectional study. SETTING Hengyang, Hunan Province, China. PARTICIPANTS Using stratified cluster random sampling, a pretested structured questionnaire was used to interview members of the general population aged ≥18 years. PRIMARY AND SECONDARY OUTCOME MEASURES Knowledge of and attitudes toward HP screening and associated health behaviours, sociodemographic factors associated with HP knowledge, and screening behaviours. RESULTS This study featured 1042 participants. The average knowledge score was 11 (QL=4, QU=20, range 0-29). Approximately 68.9% of the participants said they had heard of HP, but 67.5% had never had an HP test. The most common reasons for not undergoing screening were 'no symptoms' (55.7%) and 'lack of knowledge regarding the benefits of the test' (21.1%). Independent factors related to knowledge included age, education level, occupation, HP infection, frequency of drinking unboiled water (p<0.05). Factors independently associated with screening behaviour included occupation, average monthly income, presence/absence of indigestion, stomach discomfort or pain, and/or stomach disease and knowledge score (p<0.05). Overall, 941 (90.3%) participants never used anti-HP toothpaste, and 442 (40.5%) never used serving spoons or chopsticks. The risk factors for HP infection included eating out and eating in groups (p<0.05). CONCLUSION In China, the general population has poor knowledge of HP, but most people have a positive attitude towards HP screening. Being asymptomatic and lacking knowledge about testing were the main reasons for reluctance to be screened. These results highlight the urgent need for educational activities to raise awareness, enhance screening rates for HP, and encourage people to adopt a healthy lifestyle.

Abstract
Objectives: To evaluate the hematological parameters in dyspepsia patients infected with Helicobacter pylori (H. pylori) infection from Al Qassim province of Kingdom of Saudi Arabia (KSA). Methods: This retrospective study was carried out in Dr. Sulaiman Al-Habib Hospital, Al Qassim, KSA. The data of dyspepsia and epigastric pain patients were derived from the hospital based registration system between 2020-2021. Logistic regression models were used to investigate the correlation between the onset of H. pylori infection and anemia. Results: Among 810 enrolled patients, there were 202 (24.9%) patients with H. pylori infection and 144 (17.8%) with anemia. The prevalence of anemia in the H. pylori (+) group was not statistically higher than the H. pylori (-) group after adjusting age, red blood cell count, serum ferritin, mean corpuscular volume, platelet count, and mean corpuscular hemoglobin (p>0.05). The level of hemoglobin was almost identical in both the H. pylori (+) group and the H. pylori (-) group (p>0.05). Conclusion: The findings show that H. pylori infection may not be related to anemia in dyspepsia patients from the Central region of KSA.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) is a ubiquitous bacterium that affects nearly half of the world’s population with a high morbidity and mortality rate. Polymorphisms within the tumor necrosis factor-alpha (TNF-A) promoter region are considered a possible genetic basis for this disease.
AIM To functionally characterize the genetic variations in the TNF-A 5’-region (-584 to +107) of Sudanese patients infected with H. pylori using in silico tools.
METHODS An observational study was carried out in major public and private hospitals in Khartoum state. A total of 122 gastric biopsies were taken from patients who had been referred for endoscopy. Genomic DNA was extracted. Genotyping of the TNF-A-1030 polymorphism was performed using PCR with confronting two-pair primer to investigate its association with the susceptibility to H. pylori infection in the Sudanese population. Furthermore, Sanger sequencing was applied to detect single nucleotide polymorphisms in the 5’-region (-584 to +107) of TNF-A in H. pylori-infected patients. Bioinformatics analyses were used to predict whether these mutations would alter transcription factor binding sites or composite regulatory elements in this region. A comparative profiling analysis was conducted in 11 species using the ECR browser and multiple-sequence local alignment and visualization search engine to investigate the possible conservation. Also, a multivariate logistic regression model was constructed to estimate odds ratios and their 95% confidence intervals for the association between TNF-A-1030, sociodemographic characteristics and H. pylori infection. Differences were statistically significant if P < 0.05. Statistical analyses were performed using Stata version 11 software.
RESULTS A total of seven single nucleotide polymorphisms were observed in the TNF-A 5’-region of Sudanese patients infected with H. pylori. Only one of them (T > A, -76) was located at the in silico-predicted promoter region (-146 to +10), and it was predicted to alter transcription factor binding sites and composite regulatory elements. A novel mutation (A > T, +27) was detected in the 5’ untranslated region, and it could affect the post-transcriptional regulatory pathways. Genotyping of TNF-A-1030 showed a lack of significant association between -1030T and susceptibility to H. pylori and gastric cancer in the studied population (P = 0.1756) and (P = 0.8116), respectively. However, a significant association was detected between T/C genotype and H. pylori infection (39.34% vs 19.67%, odds ratio = 2.69, 95% confidence interval: 1.17-6.17, P = 0.020). Mammalian conservation was observed for the (-146 to +10) region in chimpanzee (99.4%), rhesus monkey (95.6%), cow (91.8%), domesticated dog (89.3%), mouse (84.3%), rat (82.4%) and opossum (78%).
CONCLUSION Computational analysis was a valuable method for understanding TNF-A gene expression patterns and guiding further in vitro and in vivo experimental validation.

Abstract
BACKGROUND AND AIMS Helicobacter pylori infection is prevalent and recognized as a major cause of gastrointestinal diseases in the world. Previous studies on the prevalence of H. pylori infection in military personnel have shown some conflicting results. This study aimed to estimate the pooled prevalence of H. pylori infection and evaluate its risk factors in military personnel. METHODS The PubMed, EMBASE, and Cochrane Library databases were searched. We pooled the prevalence of H. pylori infection in military personnel using a random-effect model. Metaregression analysis was used to explore the sources of heterogeneity. Pooled proportion of H. pylori infection with 95% confidence interval (CI) was calculated. RESULTS Sixteen studies were included. Meta-analysis showed that the overall prevalence of H. pylori infection was 32% (95% CI = 31-33) in military personnel. There was a significant heterogeneity. Metaregression analysis showed that study region (P = 0.0004) and publication year (P = 0.023) were the potential sources of heterogeneity. In the subgroup analysis by study region, the highest prevalence was found in Asia (50.2%; 95% CI = 49-51.4). In the subgroup analysis by diagnostic methods for H. pylori, the highest prevalence was found when urea breath test was employed (47.9%; 95% CI = 46.5-49.3). The most common risk factor for H. pylori infection was familial aggregation, followed by living environment and age. CONCLUSION H. pylori infection is common in military personnel. In future, we may require appropriate population screening for H. pylori infection by multiple diagnostic tests and increase the knowledge and awareness of the bacterial transmission among military personnel.

Abstract
Digestive diseases are the fourth leading cause of outpatient care in Peruvian healthcare centers, with gastritis and peptic ulcers being the most common. This is a retrospective, cross-sectional, descriptive study of secondary analysis of medical record data to evaluate the prevalence of Helicobacter pylori in patients undergoing upper digestive endoscopy during 2019 at Clinica Delgado, Lima, Peru. An association between males (PRa 1.27, 95% CI 1.10-1.48, p<0.001), age categories and upper digestive endoscopy (PRa 2.53, 95% CI 2.16-2.97, p<0.001) was reported. Based on these findings, it is recommended that other causes of gastritis be identified, especially in young women with deep chronic gastritis. Furthermore, we present a review of the scientific literature of Peru on factors associated with the positivity of Helicobacter pylori in the results of superior digestive endoscopy.

Abstract
OBJECTIVE Current evidence on the associations between plasma thyroid stimulating hormone and Helicobacter pylori infection is conflicting. Therefore, our study aimed to examine TSH in relation to H. pylori infection. METHODS Based on the US National Health and Nutrition Examination Survey (NHANES) 1999-2000, a cross-sectional study was conducted with 948 participants aged 30 to 85 years. The associations between H. pylori seropositivity and TSH were evaluated using binary logistic regression models. A subgroup analysis stratified by sex, age, and body mass index was conducted. RESULTS A higher serum TSH level was found in subjects with H. pylori seropositive than in subjects with H. pylori seronegative. A significant positive association was found between H. pylori seropositivity and TSH with increasing quartiles of hormonal levels in univariate regression models (Q4 vs Q1: OR = 1.659; 95% CI, 1.152-2.389) and in multivariate regression models (Q4 vs Q1: OR = 1.604; 95% CI, 1.087-2.367). In stratified analyses, the adjusted association of serum TSH with H. pylori seropositivity was statistically significant in male (Q4 vs Q1: OR = 1.894; 95% CI, 1.109-3.235), normal BMI (Q4 vs Q1: OR = 1.894; 95% CI, 1.109-3.235), overweight (Q4 vs Q1: OR = 2.124; 95% CI, 1.047-4.308);, obese (Q4 vs Q1: OR = 0.429; 95% CI, 0.220-0.837), and age over 60 years (Q4 vs Q1: OR = 1.999; 95% CI, 1.118-3.575). CONCLUSION High TSH levels were associated with H. pylori infection, especially among male, overweight and elderly adults.

Abstract
Helicobacter Pylori (H Pylori) that infects about 90% people of developing countries causes dyspepsia and upper gastrointestinal lesions. The aim of this study was to detect the trend of H Pylori active infection and to investigate the endoscopic findings of H Pylori infected dyspeptic patient of Bangladesh. In this prospective study, 360 dyspeptic patients (Male-251, Female-109) were recruited. Patients having alarm features, history of gastrectomy and malignancy were excluded from this study. Non-invasive fecal antigen test for H Pylori was done of all patients. All selected patients were sent for upper gastrointestinal endoscopy. Helicobacter Pylori fecal antigen was found positive in 134(37.2%) from 360 dyspeptic patients (age 14-80 years). Among 360 patients 303 (80.16%) had macroscopic endoscopic mucosal lesions. H Pylori infected 114 patients had endoscopic mucosal abnormality. H Pylori non-infected 189 patients also had mucosal lesion. Twenty patients (35.08%) had H Pylori infection among the 57 patients having endoscopic normal looking mucosa. This study revealed that active H Pylori infection rate is declining in Bangladesh. Risk of endoscopic mucosal lesion is more expected in H Pylori active infection.

Abstract
OBJECTIVES A descriptive and comparative study of gastric histological aspects according to the updated Sydney classification (USC), obtained from Helicobacter pylori-positive versus H pylori-negative children referred for upper gastrointestinal endoscopy. METHODS The Prisma method was used to perform a systematic review and meta-analysis. Selection criteria were based on following key words USC, H pylori, children, endoscopy, or biopsy. Publication biases were assessed according to the Newcastle-Ottawa Scale, and a meta-regression analysis was done. The study was registered on the PROSPERO platform. RESULTS Between 1994 and 2017, 1238 references were found; 97 studies were retained for the systematic review with a total number of 25,867 children; 75 studies were selected for the meta-analysis concerning 5990 H pylori-infected and 17,782 uninfected children.H pylori-positive versus H pylori-negative children, according to the USC, showed significantly higher relative risk for gastric antral and corpus chronic inflammation, presence of neutrophils, and of lymphoid follicles, and gastric mucosa atrophy, whereas, intestinal metaplasia showed a significantly higher RR only in antral biopsies. The meta-regression analysis showed that H pylori-positive versus H pylori-negative children had significantly higher risk only for corpus activity according to age, recurrent abdominal pain, and geographical area of low H pylori prevalence. CONCLUSIONS H pylori infection in children was associated with higher relative risk for gastric antral and corpus chronic inflammation, presence of neutrophils, lymphoid follicles, and rare gastric mucosa atrophy, whereas, rare intestinal metaplasia was only significantly higher in the antral area.

Abstract
BACKGROUND Helicobacter pylori infection and hyperglycemia are associated with an increased risk of colorectal neoplasm, and may have a synergistic effect in combination. However, these 2 factors that affect colorectal neoplasm remain controversial. We aimed to carry out a meta-analysis to evaluate the study population diabetes prevalence rate and H pylori infection rate with colorectal adenoma risk for adults. METHODS We conducted systemic research through English databases for medical reports. We also recorded the diabetes prevalence and H pylori infection prevalence in each study. We classified these studies into 4 subgroups as their background population diabetes prevalence <6% (Group 1); between 6% and 8% (Group 2); between 8% and 10% (Group 3), and more than 10% (Group 4). The random-effects model had used to calculate pooled prevalence estimates with 95% confidence interval (CI). RESULTS Twenty-seven studies were finally eligible for meta-analysis. The random-effects model of the meta-analysis was chosen, showing pooled odds ratio (OR) equal to 1.51 (95% CI 1.39-1.63). The subgroup meta-analyses showed in Group 1 the H pylori infection associated colorectal adenoma risk OR was 1.24 (95% CI 0.86-1.78). As the diabetes rate exceed 6%, the H pylori infection became the more significant increased risk of colorectal adenoma (Group 2: OR 2.16 (95% CI 1.61-2.91); Group 3: OR 1.40 (95% CI 1.24-1.57); and Group 4: OR 1.52 (95% CI 1.46-1.57)). CONCLUSIONS The results of this meta-analysis showed elevated diabetes prevalence combined H pylori infection increasing the risks of colorectal adenoma in the adult population.

Abstract
ABSTRACT The study aimed to assess demographic, clinical, and endoscopic parameters in patients with predominant corporeal atrophic gastritis (CAG) and enterochromaffin-like cell hyperplasia suggestive for autoimmune etiology in comparison with patients presenting Helicobacter pylori atrophic gastritis limited to the gastric antrum (AAG).Demographical, clinical, and pathological data of consecutive patients who underwent an upper digestive endoscopy for bleeding screening risk, symptoms, or anemia in a single endoscopy unit were retrieved. The final study group included 63 patients with CAG and enterochromaffin-like cell hyperplasia on histology and a control group of 142 patients with AAG.Female patients were predominant in the group with CAG versus AAG (69.8% vs 46.4%, P = .002). Microcytic anemia (P < .001), but not macrocytic anemia (P = .14) was associated with CAG, the mean corpuscular volume of erythrocyte (MCV) (82.5 vs 86.5 fl, P = .01), the mean value of serum iron (11.8 vs 14.3 μmol/L, P = .02), and hemoglobin level (11.0 vs 12.7 g/dL P < .01) being significantly lower in patients with CAG versus AAG. Upper digestive endoscopies with no visible mucosal lesions (P = .01) were also more frequent in the patients with CAG, but there were not differences regarding digestive symptoms between groups. The linear regression models revealed that the low hemoglobin (P < .001) and low MCV (P = .03) are the independent variables that can predict CAG on histology, but not the serum iron level (P = .77)Consecutive patients investigated on endoscopy with CAG in comparison with those having AAG are more frequent female, they have microcytic anemia, and no mucosal lesions on endoscopy. The decreased hemoglobin level and low MCV, rather than the serum iron level are predictors for CAG versus AAG on histology in endoscopic population.

Abstract
Background and aim: Since the relation between Helicobacter pylori (H. pylori) and atherosclerosis has been evidenced, we aimed to analyze whether there is a relationship between the patient's H. pylori infection and age, gender, BMI, blood lipids, and carotid plaque formation.Methods: 810 patients from January 2016 to December 2019 were enrolled in this study, and divided the subjects into H. pylori (+) group and H. pylori (-) group based on the results of UBT. To analyze whether H. pylori infection is related to gender, age, BMI, blood lipids, and neck vascular plaque formation.Results: The single-factor analysis showed that the BMI ≥ 25kg/m2, triglycerides >1.7 mmol/l, the formation of cervical plaques were significantly higher in patients infected with H. pylori in compared to normal cases. Also, multi-variant logistic regression analysis showed that H. pylori infection affects the BMI ≥ 25kg/m2 and triglycerides >1.7 mmol/l to induce vascular plaque. Also, we showed that patients with H. pylori infection are 1.424 times higher than the non-infected group to have triglycerides more elevated than 1.7mmol/l.Conclusion: In this study, we conclude that H. pylori infection is an independent risk factor for higher BMI (>25), triglyceride (>1.7 mmol/l), and neck vascular plaque formation. The multi-variant analysis showed that patients with H. pylori infection are prone to have higher BMI, triglycerides, and neck vascular plaque formation over 1.4-times higher in non-infected individuals.KEY MESSAGESH. pylori infection is an independent risk factor for higher BMI, triglyceride, and neck vascular plaque formation.H. pylori can accelerate vascular plaque formation through increasing BMI and triglyceride.

Abstract
BACKGROUND Helicobacter pylori infection is a major cause of non-cardia gastric cancer (NCGC), but its causal role in cardia gastric cancer (CGC) is unclear. Moreover, the reported magnitude of association with NCGC varies considerably, leading to uncertainty about population-based H pylori screening and eradication strategies in high-risk settings, particularly in China, where approximately half of all global gastric cancer cases occur. Our aim was to assess the associations of H pylori infection, both overall and for individual infection biomarkers, with the risks of NCGC and CGC in Chinese adults. METHODS A case-cohort study was done in adults from the prospective China Kadoorie Biobank study, aged 30-79 years from ten areas in China (Qingdao, Haikou, Harbin, Suzhou, Liuzhou, Henan, Sichuan, Hunan, Gansu, and Zhejiang), and included 500 incident NCGC cases, 437 incident CGC cases, and 500 subcohort participants who were cancer-free and alive within the first two years since enrolment in 2004-08. H pylori biomarkers were measured in stored baseline plasma samples using a sensitive immunoblot assay (HelicoBlot 2.1), with adapted criteria to define H pylori seropositivity. Cox regression was used to estimate adjusted hazard ratios (HRs) for NCGC and CGC associated with H pylori infection. These values were used to estimate the number of gastric cancer cases attributable to H pylori infection in China. FINDINGS Of the 512 715 adults enrolled in the China Kadoorie Biobank between June, 2004, and July, 2008, 500 incident NCGC cases, 437 incident CGC cases, and 500 subcohort participants were selected for analysis. The seroprevalence of H pylori was 94·4% (95% CI 92·4-96·4) in NGCG, 92·2% (89·7-94·7) in CGC, and 75·6% (71·8-79·4) in subcohort participants. H pylori infection was associated with adjusted HRs of 5·94 (95% CI 3·25-10·86) for NCGC and 3·06 (1·54-6·10) for CGC. Among the seven individual infection biomarkers, cytotoxin-associated antigen had the highest HRs for both NCGC (HR 4·41, 95% CI 2·60-7·50) and CGC (2·94, 1·53-5·68). In this population, 78·5% of NCGC and 62·1% of CGC cases could be attributable to H pylori infection. H pylori infection accounted for an estimated 339 955 cases of gastric cancer in China in 2018. INTERPRETATION Among Chinese adults, H pylori infection is common and is the cause of large numbers of gastric cancer cases. Population-based mass screening and the eradication of H pylori should be considered to reduce the burden of gastric cancer in high-risk settings.

Abstract
Severe Helicobacter pylori-linked gastric disorders are especially prevalent in the East Asia region. The ability of H. pylori to cause different clinical outcomes is thought to be associated with unique sets of its genetic features. However, only few genetic features have been definitively linked to specific gastrointestinal pathologies. Genome heterogeneity of clinical H. pylori strains from patients with four different gastric disorders was studied to explore the population structure and molecular genomic features and their association with pathogenicity. Population analysis showed that 92.9% of the Shanghai H. pylori isolates were clustered in the East Asia group. Among 2,866 genes detected in all genomes, 1,146 genes formed the core genome, whereas 209 unique genes were detected in individual disease groups. The unique genes of peptic ulcer and gastric cancer groups represented the inorganic ion transport and metabolism function gene clusters. Sixteen virulence genes were detected with statistically different detection rates among the four disease groups. Furthermore, 127 clustered regularly interspaced short palindromic repeats were found with significantly different rates in the four disease groups. A total of 337 putative genomic islands were identified, and three genomic islands were individually found in more than 10% of strains. The genomic islands included several metabolism-associated genes and many genes with unknown function. In total, 88 sequence types were detected among the 112 Shanghai H. pylori isolates. Our study provides an essential milestone in the mapping of specific genomic features and their functions to identify factors needed to induce specific gastric disorders in H. pylori.

Abstract
Objective Familial transmission can possibly influence the infection and treatment of Helicobacter pylori. This study aimed to describe the prevalence of H. pylori infection and outcomes of eradication treatment among Vietnamese patients who live in the same households. Methods We conducted a prospective cohort study of Vietnamese household members with upper gastrointestinal complaints. Participants received esophagogastroduodenoscopy and H. pylori testing. The H. pylori-positive patients were treated and asked to return for follow-up within 4 months. To explore factors associated with H. pylori infection at baseline, we performed multilevel logistic regression to account for the clustering effect of living in the same households. To explore factors associated with eradication failure, we used Poisson regression with robust variance estimation to estimate the risk ratio. Results The prevalence of H. pylori infection was 83.5% and highest among children <12 years old (92.2%) in 1,272 patients from 482 households. There were variations in H. pylori infection across households (intraclass correlation = 0.14, 95% confidence interval (CI) 0.05, 0.33). Children aged <12 years had higher odds of H. pylori infection (odds ratio = 3.41, 95%CI 2.11, 5.50). At follow-up, H. pylori was eradicated in 264 of 341 patients (77.4%). The risk of eradication failure was lower for the sequential regimen with tetracycline. Conclusion H. pylori infection was common among people living in the same households. Eradication success for H. pylori was higher for the tetracycline sequential regimen. More research should be focused on how family factors influence H. pylori infection and on eradication treatment.

Abstract
The prevalence of Helicobacter pylori infection remains significant worldwide and it depends on many factors: gender, age, socio-economic status, geographic area, diet, and lifestyle. All successful infectious diseases treatments use antibiotic-susceptibility testing, but this strategy is not currently practical for H. pylori and the usual cure rates of H. pylori are lower than other bacterial infections. Actually, there is no treatment that ensures complete eradication of this pathogen. In the context of an alarming increase in resistance to antibiotics (especially to clarithromycin and metronidazole), alternative and complementary options and strategies are taken into consideration. As the success of antibacterial therapy depends not only on the susceptibility to given drugs, but also on the specific doses, formulations, use of adjuvants, treatment duration, and reinfection rates, this review discusses the current therapies for H. pylori treatment along with their advantages and limitations. As an alternative option, this work offers an extensively referenced approach on natural medicines against H. pylori, including the significance of nanotechnology in developing new strategies for treatment of H. pylori infection.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) is a spiral-shaped bacterium responsible for the development of chronic gastritis, gastric ulcer, gastric cancer (GC), and MALT-lymphoma of the stomach. H. pylori can be present in the gastric mucosa (GM) in both spiral and coccoid forms. However, it is not known whether the severity of GM contamination by various vegetative forms of H. pylori is associated with clinical and morphological characteristics and long-term results of GC treatment.
AIM To establish the features of H. pylori infection in patients with GC and their correlations with clinical and morphological characteristics of diseases and long-term results of treatment.
METHODS Of 109 patients with GC were included in a prospective cohort study. H. pylori in the GM and tumor was determined by rapid urease test and by immunohistochemically using the antibody to H. pylori. The results obtained were compared with the clinical and morphological characteristics and prognosis of GC. Statistical analysis was performed using the Statistica 10.0 software.
RESULTS H. pylori was detected in the adjacent to the tumor GM in 84.5% of cases, of which a high degree of contamination was noted in 50.4% of the samples. Coccoid forms of H. pylori were detected in 93.4% of infected patients, and only coccoid-in 68.9%. It was found that a high degree of GM contamination by the coccoid forms of H. pylori was observed significantly more often in diffuse type of GC (P = 0.024), in poorly differentiated GC (P = 0.011), in stage T3-4 (P = 0.04) and in N1 (P = 0.011). In cases of moderate and marked concentrations of H. pylori in GM, a decrease in 10-year relapse free and overall survival from 55.6% to 26.3% was observed (P = 0.02 and P = 0.07, respectively). The relationship between the severity of the GM contamination by the spiral-shaped forms of H. pylori and the clinical and morphological characteristics and prognosis of GC was not revealed.
CONCLUSION The data obtained indicates that H. pylori may be associated not only with induction but also with the progression of GC.

Abstract
INTRODUCTION Stomach cancer is a serious global public health problem. The current burden of stomach cancer and its trends across time and location need to be understood to develop effective preventive strategies. METHODS Data were obtained from the Global Burden of Disease study. The burden of stomach cancer and variations in time and geographical regions were assessed according to the age-standardized rate and estimated annual percentage change (EAPC) of the incidence and mortality rate between 1991 and 2017. We also investigated the associations between the relevant rates and sociodemographic index (SDI). RESULTS Overall, the age-standardized incidence rate (EAPC = -1.36, 95% confidence interval [CI]: -1.47 to -1.25), age-standardized mortality rate (EAPC = -2.2, 95% CI: -2.29 to -2.12), and age-standardized disability-adjusted life years rate (EAPC = -2.52, 95% CI: -2.63 to -2.43) decreased worldwide from 1990 to 2017. This trend varied across different countries and regions and according to sex and age. SDI had a significant negative correlation with the age-standardized mortality rate (P < 0.01, r = -0.28) and age-standardized disability-adjusted life years rate (P < 0.01, r = -0.31). Similar negative correlations were observed between SDI and the EAPC. DISCUSSION The observed correlation between SDI and disease burden suggests that strategically implementing the screening and eradication of Helicobacter pylori, improving the medical level in countries with low SDI, and promoting the implementation of tobacco cessation policies would help reduce the disease burden of stomach cancer.

Abstract
BACKGROUND AND AIM Diagnostic guidelines for the investigation of dyspepsia for patients <50 years have been implemented. However, it is unsure whether these guidelines are used appropriately. We aimed to investigate the adherence to the national guidelines of uninvestigated dyspepsia and to examine the prevalence of upper gastrointestinal pathology in patients 18-50 years. We also aimed to detect any possible risk factors for pathology in esophagogastroduodenoscopy referrals and to evaluate differences between referrals from the hospital and primary health care. METHOD This is a retrospective review of medical records including patients who underwent esophagogastroduodenoscopy between January 2019 and April 2020 (n = 1809). Odds ratios (OR), positive predictive values (PPV), negative predictive values (NPV), chi-square and Mann-Whitney U-tests were applied. RESULTS In total 1708 patients were included, of whom 43.6% (n = 744) had a pathologic finding. Age group 41-50 years showed the highest prevalence with an OR 1.34 [95% confidence interval (CI), 1.07-1.69]. Helicobacter pylori testing was performed in 21.1% (n = 167) of patients with dyspepsia lacking alarm symptoms (n = 791). PPV and OR were generally low for a pathologic esophagogastroduodenoscopy. The absence of alarm symptoms showed a high NPV for significant pathology (98.7-99.6%). Significant pathology was almost exclusively found in hospital-based referrals. CONCLUSIONS Esophagogastroduodenoscopy is widely performed in young adults, often without significant findings. Adherence to the national guidelines was poor. No referral factors were associated with a significant risk for a pathologic finding. Esophagogastroduodenoscopy based on primary healthcare referrals demonstrated almost exclusively benign pathology. Significant pathology was only found via hospital-based referrals.

Abstract
BACKGROUND AND AIM Gastric precancerous conditions are generally considered to play an essential role in the gastric carcinogenesis cascade. This study identified risk factors of gastric precancerous conditions in a nationwide multicenter cross-sectional study. METHODS Individuals who made their visit to 115 hospitals in China for gastric cancer screening were recruited. Lifestyle habits and personal information were collected through a series of questionnaires. Serum biomarker test (pepsinogen I, pepsinogen II, gastrin-17, and anti-Helicobacter pylori immunoglobulin G antibody) and endoscopy were then performed. Risk factors for gastric precancerous conditions were identified by univariate and multivariate analyses. RESULTS Of 14,929 subjects eligible for analysis, 4477 (30.0%) developed gastric precancerous conditions and 405 (2.71%) developed gastric cancer. In multiple logistic regression, precancerous conditions were associated with advanced age [odds ratio (OR)=1.027; 95% confidence interval (Cl), 1.023-1.032; P<0.001], male gender (OR=1.303; 95% Cl, 1.188-1.429; P<0.001), H. pylori infection (OR=1.377; 95% Cl, 1.272-1.490, P<0.001), and smoking (OR=1.142; 95% Cl, 1.005-1.298, P=0.004), whereas they were inversely correlated with white meat intake (OR=0.731; 95% Cl, 0.673-0.794; P<0.001) and pepsinogen I level (30 to 70 subgroup OR=1.536; 95% Cl, 1.163-2.028; P=0.002; <30 subgroup OR=1.354; 95% Cl, 1.206-1.520; P<0.001). Also, the authors observed a statistically lower prevalence of reflux esophagitis (2.8% vs. 4.7%) and of gastric polyps (11.0% vs. 13.7%) in H. pylori-infected population. CONCLUSIONS Patients with H. pylori have a 1.4-fold higher risk of having gastric precancerous conditions. Besides, precancerous conditions were associated with advanced age, male gender, H. pylori infection, and smoking in a large population. However, regular white meat intake and higher pepsinogen I level were associated with reduced risk of having precancerous lesions.

Abstract
INTRODUCTION Helicobacter pylori infection during pregnancy has some adverse effects, but its effects are still conflicting. This meta-analysis study was performed to assess the relationship between H pylori infection and adverse effects during pregnancy. METHODS Through a systematic literature search up to August 2020, 31 studies included 16 887 pregnant females at baseline and reported a total of 5852 H pylori infection positive and 8196 H pylori infection negative pregnant females, were found recording relationships between H pylori infection and adverse effects during pregnancy. Odds ratio (OR) with 95% confidence intervals (CIs) was calculated between H pylori infection positive vs H pylori infection negative in adverse effects during pregnancy using the dichotomous methods with a random or fixed-effect model. RESULTS H pylori infection positive during pregnancy was significantly related to higher rate of preeclampsia (OR, 2.68; 95% CI, 2.02-3.56, P < .001), foetal growth restriction (OR, 1.45; 95% CI, 1.26-1.66, P < .001), gestational diabetes mellitus (OR, 2.63; 95% CI, 1.51-4.59, P < .001), and hyperemesis gravidarum (OR, 14.45; 95% CI, 10.24-20.38, P < .001) compared with H pylori infection negative. However, H pylori infection positive during pregnancy was not significantly correlated with spontaneous onset of labour (OR, 1.00; 95% CI, 0.83-1.21, P = .98) compared with H pylori infection negative. CONCLUSIONS H pylori infection may have an independent relationship with certain adverse effects during pregnancy. H pylori infection positive during pregnancy was significantly related to a higher rate of preeclampsia, foetal growth restriction, gestational diabetes mellitus, and hyperemesis gravidarum compared with H pylori infection negative. This relationship encouraged us to recommend screening and treating females for H pylori infection before and during pregnancy to avoid any possible complications.

Abstract
Mitochondria are essential organelles that are not only responsible for energy production but are also involved in cell metabolism, calcium homeostasis, and apoptosis. Targeting mitochondria is a key strategy for bacteria to subvert host cells' physiology and promote infection. Helicobacter (H.) pylori targets mitochondria directly. However, mitochondrial genome (mtDNA) polymorphism (haplogroup) is not yet considered an important factor for H. pylori infection. Here, we clarified the association of mitochondrial haplogroups with H. pylori prevalence and the ability to perform damage. Seven mtDNA haplogroups were identified among 28 H. pylori-positive subjects. Haplogroup B was present at a higher frequency and haplotype D at a lower one in the H. pylori population than in that of the H. pylori-negative one. The fibroblasts carrying high-frequency haplogroup displayed a higher apoptotic rate and diminished mitochondrial respiration following H. pylori infection. mtDNA mutations were accumulated more in the H. pylori-positive population than in that of the H. pylori-negative one in old age. Among the mutations, 57% were located in RNA genes or nonsynonymous protein-coding regions in the H. pylori-positive population, while 35% were in the H. pylori-negative one. We concluded that gastric disease caused by Helicobacter virulence could be associated with haplogroups and mtDNA mutations.

Helicobacter pylori (Hp) is crucial in gastric carcinogenesis, but infection alone is not a sufficient cause, and the interaction between Hp infection and other risk factors has not been adequately studied. We conducted a pooled analysis of seven case-control studies from the Stomach cancer Pooling (StoP) Project, comprising 1377 cases and 2470 controls, to explore the interaction among Hp infection and tobacco smoking, alcohol drinking, socioeconomic status (SES) and dietary salt intake on the risk of gastric cancer. We estimated summary odds ratios (ORs) and the corresponding 95% confidence intervals (CIs) by multivariate unconditional logistic regression. The analysis showed no consistent interaction between Hp infection and cigarette smoking, while interaction was more than multiplicative for alcohol drinking (OR = 1.38, 95% CI: 1.07-1.77, P-interaction 0.02) and high intake of salt (OR = 2.62, 95% CI: 1.88-3.65, P-interaction = 0.04). The interaction with SES followed the multiplicative model (P = 0.49), resulting in a weakening among infected individuals of the protective effect of high SES among observed Hp-negative individuals. The interactions found were more pronounced in subjects with history of peptic ulcer. The interactions with Hp infection were stronger for cigarette smoking and dietary salt in the case of noncardia cancer, and for alcohol and SES in the case of cardia cancer. No differences were found when stratifying for histologic type. This large-scale study aimed to quantify the interaction between Hp infection and other modifiable risk factors of gastric cancer revealed that the benefit of combined Hp eradication and lifestyle modification on gastric cancer prevention may be larger than commonly appreciated.

Abstract
BACKGROUND Gastric cancer remains a leading cause of cancer death worldwide. In Taiwan, gastric cancer is the sixth leading cause of cancer mortality in both males and females.
AIM To evaluate secular trends in gastric cancer incidence according to age, sex, and Helicobacter pylori (H. pylori) treatment in Taiwan.
METHODS In this population-based study, we used the national Taiwan Cancer Registry database. Annual percent changes in incidence rates were used to describe secular trends in incidence rates and sex ratios of gastric cancer in Taiwan. Pearson’s product-moment correlation coefficients were used to analyze the correlation between annual age-adjusted incidence rates and the annual number of patients treated with antibiotic therapy for H. pylori infection.
RESULTS The annual percent changes showed continuously decreasing rates of gastric cancer among both males and females. However, the decreasing trends differed by sex, with an annual percent change of -2.58% in males and -2.14% in females. The age-specific incidence rates increased with age. Within the same age group, more recent time periods showed lower incidence rates than greater time periods. Similarly, the sex ratio was lower in later birth cohorts than in earlier birth cohorts. Age-adjusted incidence rates substantially decreased with increasing numbers of patients being treated with antibiotic therapy for H. pylori infection during 2005 to 2016 (r = 0.72).
CONCLUSION We observed steadily decreasing trends with differential sex ratios in the incidence of gastric cancer in Taiwan. These results support H. pylori eradication programs in Taiwan.

Abstract
PURPOSE The aim of this study was to evaluate the expression of miR-125a-5p in patients with dyspeptic symptoms and gastric cancer, correlating them with the development of this cancer and H. pylori. METHODS Patients were divided in groups according to histopathological analysis (control, gastritis, and cancer groups). Polymerase chain reaction was performed to detect H. pylori and real-time quantitative PCR to determine miR-125a-5p expression. RESULTS H. pylori was detected in 44% of the patients, with prevalence in the gastritis and cancer groups. A statistically significant decrease of miR-125a-5p expression was found in the control positive (p = 0.0183*), gastritis positive (p = 0.0380*), and cancer positive (p = 0.0288*) groups when compared with the control negative group. CONCLUSION We suggest that decreased expression of the miRNA-125a-5p associated with the presence of the H. pylori is an important mechanism in gastric diseases and could be a possible marker for early diagnosis of gastric cancer.

Abstract
INTRODUCTION Association of Helicobacter pylori (HP) infection with the length of dialysis in dialysis patients is contradictory. This study was conducted in order to determine the association between the duration of dialysis and the HP infection status in the dialysis patients. Furthemore, biochemical parameters were monitored in two subject groups that were included in this study. SUBJECTS AND METHODS The study included 51 patients on chronic hemodialysis program who had gastrointestinal symptoms. The subjects were divided in two groups per the length of dialysis treatment. In this study we analyzed age, gender, the time period since the onset of the chronic hemodialysis program, body mass index, biochemical parameters, and whether the patients have arterial hypertension and/or diabetes. The presence of HP antigen was determined in the stool samples with use of he UlcoGnost AG test plate. RESULTS The incidence of HP infection in hemodialysis patients, with some of the gastrointestinal symptoms, was 25.5%. Patients on hemodialysis for less than 24 months had lower incidence of HP infection than those on hemodialysis program for more than 24 months. HP positive and HP negative subjects were also compared by gender, age, biochemical parameters and body mass index. There was no statistical significant difference between the groups in any of those characteristics. When comparing the HP status of the subjects with the presence of arterial hypertension and diabetes, no statistically significant difference was found between the groups. CONCLUSION This study showed negative correlation between HP infection and the length of hemodialysis program. Analysis of age, gender, body mass index, biochemical parameters, presence of arterial hypertension and/or diabetes showed no statistically significant difference was found between the hemodialysis patients who were HP positive and those who were HP negative. Additional studies are needed to elucidate the correlation mechanism between the HP infection and the duration of dialysis, in order to examine how long the dialysis time period is the most susceptible to HP infection, and then to improve the prognosis of patients with renal disease.

Abstract
BACKGROUND Helicobacter pylori is common in developing countries like Nigeria with significant morbidity and risk of mortality. With rising antimicrobial resistance, risk factors of infection should be explored to develop prevention strategies and improve the health of developing communities. OBJECTIVE To identify determinants and clinical correlates of H. pylori among study participants. METHODS We conducted a hospital-based cross-sectional study between May and July 2017 of 280 dyspeptic adults in Garki Hospital Abuja. They were tested using serum H. pylori Immunoglobulin G antibody test kits. Data on patient characteristics were collected using pre-tested interviewer administered questionnaires. The data were analysed using SPSS version 25. Logistic regression and odds ratios with 95% confidence intervals were computed to identify risk factors and clinical features associated with H. pylori infection. RESULTS The overall prevalence of H. pylori infection was 53.6%. H. pylori was positively associated with age and monthly income. Family history of dyspepsia (OR = 0.32: 95% CI = 0.13 to 0.78), regular consumption of fruits and vegetables (OR = 0.11: 95% CI = 0.046 - 0.281) and regular handwashing with soap and water (OR = 0.02: 95% CI = 0.006 -0.040) were found to be protective against H. pylori infection. CONCLUSION There is a high H. pylori prevalence amongst patients with dyspepsia in Garki Hospital Abuja. Interventions to reduce the incidence of H. pylori infection should emphasise regular handwashing with soap and water and regular fruit and vegetable consumption.

Abstract
Background Hypochlorhydria (gastric pH >4) increases susceptibility to diarrhoea, iron deficiency, and gastric cancer. We sought to clarify the prevalence of this condition and its predisposing factors in Zambia by pooling data from previous studies conducted in hospital and community settings. Methods Gastric pH was measured in participants from five separate studies by collecting gastric aspirate from fasted adults and children under 3 years of age undergoing gastroscopy. Gastric pH was correlated with serological testing for Human Immunodeficiency Virus (HIV) and Helicobacter pylori (H. pylori) infections. Results We studied 597 individuals (487 adults and 110 children). Hypochlorhydria was present in 53% of adults and 31% of children. HIV infection was detected in 41% of adults and 11% of children. H. pylori serology was available for 366 individuals: 93% of adults and 6% of children were seropositive. In univariate analysis, hypochlorhydria was significantly associated with HIV seropositivity (OR 1.7; 95% CI 1.2–2.4; p = 0.004) and H. pylori antibody seropositivity (OR 4.9; 95% CI 2.8–8.6; p<0.0001), and with advancing age in HIV negative individuals (p = 0.0001). In multivariable analysis, only H. pylori was associated with hypochlorhydria (OR 4.0; 95% CI 2.2–7.2; p<0.0001) while excluding possible exposure to proton pump inhibitors. Conclusions Hypochlorhydria is common in our population, with H. pylori being the dominant factor. Only young HIV seronegative individuals had a low prevalence of hypochlorhydria. This may have implications for the risk of other health conditions including gastric cancer.

Abstract
OBJECTIVES To investigate whether gastric Helicobacter pylori (H. pylori) infection is associated with the progress of nonalcoholic fatty liver disease (NAFLD) in Dali city, China. METHODS One thousand and one hundred eighty-five adults who had visited a health examination center were enrolled. Nonalcoholic fatty liver disease and H. pylori infection were assessed by abdominal color ultrasound and 13C-urea breath test, respectively. Serum lipid metabolic indices were compared between NAFLD subjects without and with H. pylori infection. RESULTS The prevalence rate of NAFLD for the entire study population (n=1185) was 44.6% (n=529), including 167 women and 362 men. Among 529 NAFLD subjects, H. pylori was confirmed as a significant and independent risk factor for NAFLD (95% CI 1.02-1.79, p=0.036, OR =1.35). Compared with H. pylori non-infected individuals (n=721), higher contents of LDL-C (p=0.012) along with TC (p=0.014) were also observed in H. pylori-infected individuals (n=464). CONCLUSION A positive correlation is identified between H. pylori infection and NAFLD.

Abstract
Objectives: To investigate prevalence and association between iron deficiency anemia (IDA) and Helicobacter pylori(H. pylori). Methods: This cross-sectional study included 79 participants with unexplained IDA. The study was carried out between November 2018 to April 2020 in the College of Medicine, Umm Al-Qura University in collaboration with Al-Noor Specialist Hospital, Makkah, Saudi Arabia. Complete blood count (CBC), serum iron, and ferritin levels were measured. Anti-H. pylori antibody was detected using anti-H. pylori immunoglobulin G enzyme-linked immunosorbent assay (ELISA). Results: The prevalence of H. pylori infection among IDA patients was 62%. There was a significant difference between female and male subjects with a positive H. pylori status (p=0.001). There was also a significant difference between females and males with a positive H. pylori infection according to red blood cell count, hematocrit, mean corpuscular volume, and mean cor-puscular hemoglobin (p=0.001). Conclusion: The current study shows an association between H. pylori infection and unexplained IDA with significant difference between postmenopausal Saudi females and males. This will lead to more effective treatment in IDA and the eradication of H. pylori, as well as the prevention of recurrence, which are necessary and may provide a significant reduction in the overall disease burden.

Abstract
BACKGROUND The relationship between Helicobacter pylori (H. pylori) infection and nonalcoholic fatty liver disease (NAFLD) is a matter of debate. Although it has been studied in many observational studies, the results remain controversial. Therefore, we performed a meta-analysis to assess the association between H pylori infection and risk of NAFLD. METHODS We searched Pubmed, EMBASE, and Web of Science databases, from inception to September 10, 2020. Odds ratio (OR) and 95% confidence interval (CI) were pooled by random-effects model. The statistical heterogeneity among studies (I2-index), subgroup analyses, regression analyses, sensitivity analysis and the possibility of publication bias were assessed. RESULTS A total of seventeen studies involving 91,958 individuals were included in our meta-analysis. Meta-analysis of data from cross-sectional and case-control studies showed that H pylori infection was associated with increased risk of prevalent NAFLD (n = 15; involving 74,561 middle-aged individuals; OR1.38, 95% CI 1.23-1.55, I2 = 86.8%, P < .001). The results of meta-regression implicated that the study type and the case-control ratio impacted the total effect size. Funnel plot did not show significant publication bias. Meta-analysis of data from longitudinal studies showed that H pylori infection was also associated with increased NAFLD incidence (n = 2; involving 17397 individuals; OR 1.21, 95% CI 1.01-1.44, I2 = 6.5%, P = .301). CONCLUSIONS The results indicated that a positive association between H pylori infection and the risk of NAFLD. Further studies are required to strengthen the association and clarify the mechanism.

Abstract
It is often difficult to explain why ulcerative lesions are found in the small intestine because there are no obvious aggressors such as gastric acid. In particular, the treatment of small intestinal ulcerative lesions in asymptomatic patients with no symptoms, normal physical examinations, and normal blood test findings is not well documented. According to a summary of capsule endoscopy studies in healthy subjects, approximately 10% of subjects have small intestinal mucosal breaks. The number of mucosal breaks in these instances is approximately 1-3. We examined small intestinal mucosal breaks in healthy subjects recruited from our past two studies. Mucosal breaks were observed in approximately 10% of subjects, and the average number was 0.24 ± 1.21. The number of mucosal breaks in the small intestine was correlated with body mass index and was significantly higher in Helicobacter pylori-infected subjects and higher in males. These results indicate that 1-2 small ulcerative lesions, such as erosions in the small intestine, can be considered to be in the normal range, and close examination is not required. It is assumed that a follow-up medical examination is required for such asymptomatic persons. The presence of many small ulcerative lesions or an unequivocal ulcer indicates an abnormality for which close examination is desired. However, in many cases, it is sufficient to scrutinize after detecting anemia, but it is difficult to make a judgment due to insufficient reports, and future studies are required.

Abstract
Pepsinogen (PG) I and II are crucial in the gastric digestive processes. This study is to examine the relationship of serum PGI, PGII, and PGI/PGII ratio with Helicobacter pylori (Hp) infection, age, sex, and body mass index (BMI) in subjects in Beijing, China.A total of 40,383 asymptomatic subjects, who underwent medical examination in Beijing Rehabilitation Hospital, were included in this study. Serum PG levels were measured using chemoluminescence techniques. The age, sex, and BMI data were collected, and Hp infection was identified with 13C-urea breath test. Statistical analysis was conducted with Python, Pandas and Seaborn software.Asymptomatic subjects with Hp infection (Hp+) had a significantly higher level of PGI in the serum (111 ng/mL [median]) than those without Hp infection (Hp-) (94 ng/mL, P < .001). The asymptomatic Hp+ subjects had 2-fold higher PGII levels (7.2 ng/mL) than Hp- subjects (3.2 ng/mL, P < .001). These changes produced significantly lower PGI/II ratio in Hp+ patients than in Hp- subjects (16:30, P < .001). The serum PGI and PGII levels were higher in males than in females (PGI: 104 ng/mL vs 95 ng/mL, PGII: 4.3 ng/mL vs 3.7 ng/mL, both P < .001), PGI/II ratio of males is at 95% of that in females (P < .001). PGI and PGII levels gradually increased in older people (P < .001), whereas the PGI/II ratio decreased significantly with age (P < .001). The levels of the two serum PGs were decreased and the ratio increased when BMI were higher than 28 kg/cm2 (P < .05).The levels of serum PGI, especial PGII, were increased by Hp infection, and also influenced by age, sex, and BMI. Therefore, these influencing factors should be considered during clinical practice.

Abstract
OBJECTIVE The relationship between Helicobacter pylori and the intestinal microbiota has not yet been clearly demonstrated in children and adolescents. The present study aimed at evaluating how H. pylori infection could affect the intestinal microbiota in adolescents using genetic analysis. DESIGN Cross-sectional study. SETTING AND PARTICIPANTS We included subjects from a longitudinal project involving H. pylori screening and treatment of junior high school third-grade students (aged 14 or 15 years) in Saga Prefecture. The study included a control group (n=79) and an H. pylori group (n=80) tested negative and positive for the anti-H. pylori antibody in the urine and H. pylori antigen in stool specimens, respectively. INTERVENTIONS The intestinal microbiota was evaluated in stool specimens using 16S rRNA gene/DNA/amplicon sequencing with next-generation sequencing. PRIMARY AND SECONDARY OUTCOME MEASURES We assessed alpha and beta diversity, just as well as relative abundances within the bacterial composition at the genus level in both groups. RESULTS As shown by the alpha diversity of the 16S rRNA gene/DNA/amplicon sequence data, the control group exhibited lower microbial species richness with lower alpha diversity compared with the H. pylori group (p<0.001). The beta diversity of the intestinal microbiota profile also differed between the two groups (p<0.01). The relative abundance of the Prevotella genus was higher in the H. pylori group (p<0.01) concomitant with a gain in body mass index (BMI) in the H. pylori group (p<0.01) compared with the control group. CONCLUSION H. pylori infection significantly affected the intestinal microbiota in Japanese adolescents. In addition, the prevalence of the Prevotella genus is concomitantly increased along with the BMI in H. pylori-infected students. TRIAL REGISTRATION NUMBER UMIN000028721.

Abstract
Helicobacter pylori (H. pylori) infection has become an emerging problem in Indonesia despite its relatively low prevalence as opposed to other Southeast Asian and Asian countries. Strains containing less virulent genotypes predominantly found in Indonesia is suggested to be the rationale for why the disease prevalence, as well as its gastric cancer complication, remain inferior in respect of neighboring counterparts. Although endoscopic evaluation is still necessary to determine the gastric mucosal status of those infected with H. pylori, the infection itself can be easily diagnosed with test-and-treat strategy especially in areas with limited resources. Several findings revealed high rates of antibiotic resistance varying among Indonesian regions and ethnicities, suggesting that triple therapy regimen may not be suitable for all population. Whereas treatment should be based on the pattern of resistance in respected region, novel regimens involving furazolidone, rifabutin, and sitafloxacin are proposed as potential drugs of choice to eradicate H. pylori infection. In order to determine the adequate approach for H. pylori infection in Indonesia, further multicenter studies involving larger sample size should be conducted.

Abstract
PURPOSE This study aimed to determine the proportion of gastric cancer attributable to Helicobactor pylori in the Korean population. Infection with H. pylori has been recognized as the most significant risk factor for gastric cancer. In Korea, gastric cancer is the most common cancer that accounted for 13.3% of all cancers in 2016. In particular, men are most commonly diagnosed with gastric cancer; the age-standardized incidence rate in men is 49.6 per 100,000, which is more than twice the incidence in women. MATERIALS AND METHODS The population attributable fraction (PAF) was calculated as a function of the relative risk (RR) of gastric cancer associated with H. pylori infections. To estimate PAF of gastric cancer due to H. pylori, the prevalence of H. pylori infections was extrapolated for the year of 1990 and a pooled RR was obtained by conducting a meta-analysis of studies recently published in Korea. RESULTS The estimated prevalence of H. pylori was 76.4% in men and 71.9% in women. The RRs (95% confidence interval) pooled from case-control studies using a random effects model was 1.69 (1.29-2.22) for overall gastric cancer and 2.17 (1.04-4.55) for non-cardia gastric cancer. Using the RR for overall gastric cancer, the estimated PAFs due to H. pylori were 34.5% in men and 33.2% in women. CONCLUSION The occurrence of gastric cancer in Koreans may be affected by other risk factors in addition to H. pylori infection, which may contribute to increasing baseline risk for gastric cancer.

Abstract
Helicobacter pylori infection is one of the most common infectious diseases worldwide. H. pylori is responsible for substantial gastrointestinal morbidity with a high disease burden. Since the revision of the H. pylori Clinical Practice Guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin based triple therapy. According to a nationwide randomized controlled study by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance to clarithromycin. The clinical practice guidelines for treatment of H. pylori were updated based on evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after expert consensus on three recommendations regarding the indication for treatment and eight recommendations on the treatment itself. These guidelines were designed to provide clinical evidence for the treatment of H. pylori to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards, and will be revised if more evidence emerges in the future.
