Abstract
Gastroduodenal diseases have prevailed for a long time and more so due to dominance of gut bacteria Helicobacter pylori in most of the cases. But habitation by other gut microbiota in gastroduodenal diseases and the relationship between Helicobacter pylori and gastrointestinal microbiota in different gastroduodenal diseases is somewhat being unravelled in the current times. For this systematic review, we did a literature search of various gastroduodenal diseases and the effect on gut microbiota pertaining to it. A search of the online bibliographic databases PUBMED and PUBMED CENTRAL was carried out to identify articles published between 1977 and May 2022. The analysis of these selected studies highlighted the inhabitation of other gut microbiota such as Fusobacteria, Bacteroidetes, Streptococcaceae, Prevotellaceae, Fusobacteriaceae, and many others. Interplay between these microbiota and H. pylori have also been noted which suggested that gastroduodenal diseases and gut microbiota are intertwined by a symbiotic association regardless of the H. pylori status. The relationship between the gut microbiota and many gastroduodenal diseases, such as gastritis, gastric cancer, lymphomas, and ulcers, demonstrates the dysbiosis of the gut microbiota in both the presence and absence of H. pylori. The evolving ways for eliminating H. pylori are provided along with inhibiting qualities of other species on H. pylori. Most significant member of our gut system is Helicobacter pylori which has been associated with numerous diseases like gastric cancer, gastritis, duodenal ulcer.

Abstract
BACKGROUND AND AIMS Previous studies have reported the association between limited number of Helicobacter pylori (H. pylori) antigens and gastric cancer (GC) risk. The present study evaluated the association between serum antibodies against 15 different H. pylori proteins measured by using multiplex serology assay and GC risk. METHODS We searched PubMed databases, Embase, Web of Science, and Cochrane Library for relevant articles. A meta-analysis was used to pool studies and to estimate odds ratios (ORs) with 95% confidence intervals (95%CIs) of different H. pylori antigens associated with GC risk. Heterogeneity was investigated using Cochran's Q test and I-squared statistic. RESULTS Nine studies were identified, with a total of 3209 GC cases and 6964 controls. Five H. pylori virulence factors were significantly associated with non-cardia GC risk at p-value <0.0033 including: CagA (OR = 3.22, 95%CI: 2.10-4.94), HP0305 (OR = 1.72, 95%CI: 1.32-2.25), HyuA (OR = 1.42, 95%CI: 1.13-1.79), Omp (OR = 1.83, 95%CI: 1.30-2.58), and VacA (OR = 2.05, 95%CI: 1.67-2.52). However, none of the 15 antigens was associated with cardia GC risk. In subgroup analysis by ethnicity, we identified 7 antigens associated with the risk of non-cardia GC among East Asian while only two antigens were identified in European population. Nevertheless, CagA and GroEL showed a stronger association in Caucasian (CagA OR = 5.83, 95%CI: 3.31-10.26; GroEL OR = 3.66, 95%CI: 1.58-8.50) compared with East Asian (CagA OR = 2.20, 95% CI: 1.85-2.61; GroEL OR = 1.47, 95%CI: 1.29-1.68). CONCLUSIONS This study determined that H. pylori infection increases the risk of non-cardia GC with differential effects by its virulence factors and with different patterns among East Asian and European populations. These results advance the understanding of the effect of H. pylori on GC.

Abstract
BACKGROUND Variation in Helicobacter pylori (H. pylori) disease in terms of prevalence and antibiotic resistance prevails globally requiring a need to develop region-specific surveillance. We aimed to assess the influence of immigration factors upon the interpretation of local Singaporean epidemiological trends in antimicrobial susceptibility patterns and therapeutic outcomes in children with culture-positive H. pylori. MATERIALS AND METHODS We retrospectively analyzed eradication outcomes of children with culture-proven H. pylori infections between 2011 and 2020 at our center, and we also analyzed the antimicrobial susceptibility profiles of the corresponding H. pylori isolates. The cohort was classified into two groups: (1) Native Singaporeans and (2) Non-native Singaporeans (First-/Second-generation immigrants and Non-residents) to correlate with resistance patterns and eradication outcomes. H. pylori culture was done via Kirby-Bauer disk diffusion for the era 2011-2016 and bioMérieux E test for 2016-2020. RESULTS A total of 70 children (median age 14 [2-17] years) were included in the analysis. 42.9% (30/70) of the cohort displayed some form of antibiotic resistance; clarithromycin resistance was the most prevalent (30.0%), followed by metronidazole (27.5%) and amoxicillin (7.1%). Comparing to natives, non-native Singaporeans were significantly younger at presentation (mean 11.7 vs. 13.7 years, p = 0.043), and a significantly higher proportion of non-natives carried clarithromycin-resistant (51.4% vs. 8.6%, p < 0.001), metronidazole-resistant (47.1% vs. 8.6%, p < 0.001), or multidrug-resistant (resistant to ≥2 drugs) (40.0% vs. 2.9%, p < 0.001] strains. Non-natives were significantly more likely to fail first-line eradication therapy (48.5% failure vs. 23.3%, p = 0.038). The proportion of pan-sensitive H. pylori was significantly lower in first-generation (25.0%, p = 0.001) and second-generation (42.9%, p = 0.018) immigrants compared to natives (82.86%). These conclusions did not vary when the analysis was repeated for each culture method. CONCLUSIONS An antibiotic susceptibility-based approach should be advocated for all patients but especially so for non-natives, who are at higher risk for antimicrobial resistant strains and poorer eradication outcomes.

Abstract
The development of sequencing technology has expanded our knowledge of the human gastric microbiome, which is now known to play a critical role in the maintenance of homeostasis, while alterations in microbial community composition can promote the development of gastric diseases. Recently, carcinogenic effects of gastric microbiome have received increased attention. Gastric cancer (GC) is one of the most common malignancies worldwide with a high mortality rate. Helicobacter pylori is a well-recognized risk factor for GC. More than half of the global population is infected with H. pylori, which can modulate the acidity of the stomach to alter the gastric microbiome profile, leading to H. pylori-associated diseases. Moreover, there is increasing evidence that bacteria other than H. pylori and their metabolites also contribute to gastric carcinogenesis. Therefore, clarifying the contribution of the gastric microbiome to the development and progression of GC can lead to improvements in prevention, diagnosis, and treatment. In this review, we discuss the current state of knowledge regarding changes in the microbial composition of the stomach caused by H. pylori infection, the carcinogenic effects of H. pylori and non-H. pylori bacteria in GC, as well as the potential therapeutic role of gastric microbiome in H. pylori infection and GC.

Abstract
Background The health of individuals is not only the absence of disease checked medically, but also encompasses social and psychological aspects. Any departure from the state of physiological, psychological, or social well-being was affected by different factors. However, all contributory factors were not equally responsible for affecting disease. This study was undertaken as a search for the relative effects of sociocultural and individual behavioral factors contributing to acute and chronic gastritis patients visiting Saint Paul Hospital Millennium Medical College (SPHMMC). Methods A cross-sectional study was carried out on 364 patients visited SPHMMC in the study. Primary data were collected through an interview schedule tool with an exit approach by validating questions pertaining to sociocultural and individual behavioral factors. The status of gastritis was measured as whether patients had Helicobacter Pylori infection, signs and symptoms indicated gastritis that occurred, and persisted for less than a month, greater than a month, or none of the signs and symptoms. Descriptive statistics, bivariate analysis, and multivariable ordinal logistic regression model were used to identify the predictors of gastritis severity. P-value ≤ 0.05 was declared as an indicator of statistically significant. Results The prevalence of gastritis in the study area was 78.8%. Specifically, 48.9% and 29.9% had acute and chronic gastritis, respectively. The study found that low income and taking medicinal drugs was slightly significantly contributed to higher gastritis status; however, being younger age was slightly significantly contributed to lower gastritis status. Furthermore, the results indicated that eating spiced foods (Adjusted Odds Ratio (AOR) = 1.508; 95% CI: 1.046, 2.174), lack of physical exercise regularly (AOR = 1.780; 95% CI: 1.001, 3.168), stress (AOR = 2.168; 95% CI: 1.379, 3.4066), and substance use (AOR = 1.478; 95% CI: 1.093, 1.999) were significantly contributed to higher gastritis status. Conclusions The findings suggested that women should take enough rest and sleep well, men refrain from involvement in any risky behaviors, young people and those who earn low income per month should equip with knowledge and understanding on how to practice good health behaviors, eating foods on time, avoiding eating spiced food frequently, doing physical exercise regularly, and taking medicinal drugs according to physician advice are recommended.

Abstract
This review summarizes the recent knowledge on the epidemiology of Helicobacter pylori and the potential modes of transmission. In addition to English language publications, the authors have included original full-text publications from Russia and Latin America published in the original languages. High H pylori prevalence has been reported in Russia, Jordan, Iran, China, and Latin American countries as well as in Arctic populations in Canada. Indigenous inhabitants in the Arctic were found to be infected substantially more frequently than non-indigenous inhabitants. In Amsterdam, the Netherlands, the ethnic minority groups were at a significantly higher risk of being H pylori seropositive compared to the Dutch population. For the first time, data on the prevalence from Armenia have been published indicating 41.5% H pylori prevalence. Convincing evidence on the decline of H pylori prevalence in Southeast Hungary and Taiwan was published. A study from Chile suggested high infection rates in newborns during the first month after birth. Two meta-analyses covered the potential correlation between H pylori and periodontal diseases, therefore addressing the potential oro-oral transmission rates. Periodontal disease was found to be more prevalent in H pylori-infected subjects. Other studies addressed the potential role of drinking water and food products as well as socioeconomic factors in transmitting the infection. Several studies in Asia addressed annual reinfection rates of H pylori, ranging from 1.5% in China to 3.1% in Korea. Finally, a review was published on the current evidence and future perspective of analysing H pylori in ancient human remains by a metagenomic approach.

Abstract
Background: Helicobacter pylori and intestinal parasites are estimated to infect with high burden worldwide. However, their concomitant infections are poorly determined in industrialized countries, such as Italy. In this study we aim at describing the presence of H. pylori as well as the proportion of coinfections with intestinal parasites among subjects who attended a referral center for tropical diseases in Northern Italy. Methods: This was a case-control study. Screening for H. pylori and parasites was performed on stool samples of 93 adults from different geographical origin (Africa, Asia, South-America, East-Europe and Italy). H. pylori infection was examined by CLIA and its cagA positivity was determined by rtPCR. Intestinal parasites (i.e., protozoa and helminths) were examined by microscopy and rtPCR. Results: Sixty-one out of 93 patients (66%) were positive to H. pylori and 31 (33%) were cagA+. Among H. pylori positives, 45 (74%) had a concomitant infection. The coinfection H. pylori–Blastocystis was the most frequent one, followed by H. pylori–E. coli. Multivariable logistic regression showed that positivity to H. pylori was associated with having a coinfection. Conclusion: Our data suggested that H. pylori and intestinal parasitic infections are fairly common in subjects who attended a referral center for tropical diseases in Northern Italy. The high rate of H. pylori infection, and especially the positivity to the virulent cagA+, should be taken into consideration in subjects undergoing screening for parasitic infections.
