Food Sci Nutr 2024; 12:5019-5026. [PMID: 39055221 PMCID: PMC11266909 DOI: 10.1002/fsn3.4152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 02/28/2024] [Accepted: 03/24/2024] [Indexed: 07/27/2024] Open
Abstract
The components in our food are known as one of the important risk factors for the development of Helicobacter pylori (H. pylori) infection. A balanced diet, rich in fruits and vegetables, and free of fat, sugar, and salt, might protect people from the consequences of H. pylori infection. Therefore, the purpose of this study was to investigate the associations between ultra-processed foods (UPFs) intake and the risk of H. pylori infection. The case-control study was conducted to assess the intake of UPFs in patients with H. pylori infection compared with healthy individuals. The dietary data of the contributors were collected by a validated food frequency questionnaire (FFQ). To estimate the UPFs intake, the classification of the NOVA food group was utilized. The associations of intake UPFs with H. pylori infection were assessed using binary logistic regression. Finally, dietary data of 150 cases and 302 controls (mean age: 39.5 ± 10.95 years) were analyzed. UPFs intake was associated with higher risk of H. pylori infection (odds ratio (OR) = 1.71; 95% confidence interval (CI): 1.05, 2.79). The association remained constant after adjustment for age, body mass index (BMI), sex, energy intake, physical activity, smoking, and alcohol status (OR = 2.17; 95% CI: 1.22, 3.86). Our data declare that UPFs consumption could have a role in increasing the likelihood of the risk of H. pylori infection. To confirm the current findings, prospective studies are suggested.

Abstract
BACKGROUND Diet plays an important role in Helicobacter pylori (HP) infection, and our objective was to investigate potential connections between dietary patterns, specific food groups, and HP infection status in U.S. adults. METHODS The data for this study was obtained from the NHANES (National Health and Nutrition Survey) database for the year 1999-2000. This cross-sectional study involved the selection of adults aged 20 years and older who had undergone dietary surveys and HP testing. Factor analysis was employed to identify dietary patterns, and logistic regression models were utilized to assess the association between these dietary patterns and specific food groups with HP infection status. RESULT Based on the inclusion and exclusion criteria, our final analysis included 2,952 individuals. The median age of participants was 51.0 years, and 48.7% were male. In the study population, the overall prevalence of HP infection was 44.9%. Factor analysis revealed three distinct dietary patterns: High-fat and high-sugar pattern (including solid fats, refined grains, cheese, and added sugars); Vegetarian pattern (comprising fruits, juices, and whole grains); Healthy pattern (encompassing vegetables, nuts and seeds, and oils). Adjusted results showed that the high-fat and high-sugar pattern (OR = 0.689, 95% CI: 0.688-0.690), vegetarian pattern (OR = 0.802, 95% CI: 0.801-0.803), and healthy pattern (OR = 0.717, 95% CI: 0.716-0.718) were all linked to a lower likelihood of HP infection. Further analysis of the high-fat and high-sugar pattern revealed that solid fats (OR = 0.717, 95% CI: 0.716-0.718) and cheese (OR = 0.863, 95% CI: 0.862-0.864) were protective factors against HP infection, while refined grains (OR = 1.045, 95% CI: 1.044-1.046) and added sugars (OR = 1.014, 95% CI: 1.013-1.015) were identified as risk factors for HP infection. CONCLUSION Both the Vegetarian pattern and the Healthy pattern are associated with a reduced risk of HP infection. Interestingly, the High-fat and High-sugar pattern, which is initially considered a risk factor for HP infection when the score is low, becomes a protective factor as the intake increases. Within this pattern, animal foods like solid fats and cheese play a protective role, while the consumption of refined grains and added sugars increases the likelihood of HP infection.

Prevalence of Helicobacter pylori infection among Slovenian children and adolescents: A prospective cohort study. Helicobacter 2024; 29:e13082. [PMID: 38680036 DOI: 10.1111/hel.13082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 04/10/2024] [Accepted: 04/15/2024] [Indexed: 05/01/2024]
Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is primarily acquired in childhood and is notably influenced by socioeconomic variances across different geographical regions. The aim of this study is to assess the prevalence of H. pylori infection in Slovenian children and to identify potential risk factors that facilitate the infection. MATERIALS AND METHODS Between 2019 and 2022, we conducted a multi-center prospective cross-sectional study among healthy children residing in three different administrative regions in Slovenia. H. pylori infection status was determined using a monoclonal antibody-based stool antigen test (SAT). A standardized questionnaire was designed to evaluate the influence of various H. pylori-associated risk factors, including demographics and socioeconomic, housing and sanitation conditions. RESULTS During the 3-year period, we recruited a total of 421 children and adolescents (age range 2-18 years, mean age 10.29 ± 4.95 years). Overall, 46 (10.9%) were diagnosed with H. pylori infection. No associations were found between H. pylori prevalence rates and increasing age, sex, parental education level, country of birth of the child or their parents, number of household members, household income, having a dishwasher, owning a pet, duration of breastfeeding, fruit intake frequency, drinking tap water, and handwashing practices. The only parameters associated with an increased risk of infection were the location of the school (p < 0.001) and living in an urban area (p = 0.036). The odds of infection were approximately 4.77 times higher if the child attended school in the Central Slovenian compared to other regions (OR = 4.77; 95% CI 0.87-2.34). CONCLUSIONS This is the first study providing information on the prevalence of H. pylori infection among Slovenian children and adolescents. Using SAT, we have shown that the burden of H. pylori infection in our pediatric population is low; however, it seems to depend on regional rather than socioeconomic factors.

Abstract
Gastric cancer (GC) is a global public health concern that poses a serious threat to human health owing to its high morbidity and mortality rates. Due to the lack of specificity of symptoms, patients with GC tend to be diagnosed at an advanced stage with poor prognosis. Therefore, the development of new treatment methods is particularly urgent. Chronic atrophic gastritis (CAG), a precancerous GC lesion, plays a key role in its occurrence and development. Oxidative stress has been identified as an important factor driving the development and progression of the pathological processes of CAG and GC. Therefore, regulating oxidative stress pathways can not only intervene in CAG development but also prevent the occurrence and metastasis of GC and improve the prognosis of GC patients. In this study, PubMed, CNKI, and Web of Science were used to search for a large number of relevant studies. The review results suggested that the active ingredients of traditional Chinese medicine (TCM) and TCM prescriptions could target and improve inflammation, pathological status, metastasis, and invasion of tumor cells, providing a potential new supplement for the treatment of CAG and GC.

Abstract
Background Helicobacter pylori (H. pylori) is a group 1 carcinogen and the etiological agent of gastric diseases such as gastritis, ulcers, and gastric cancer. It infects approximately half of the world's population. Risk factors associated with H. pylori infection include socioeconomic status, lifestyle, and diet. Objectives This study aimed to evaluate the association between eating habits and H. pylori infection in patients from a reference hospital in Central Brazil. Design This cross-sectional study included 156 patients from 2019 to 2022. Methods Data were collected using a structured questionnaire on sociodemographic and lifestyle characteristics and a validated food frequency questionnaire. The H. pylori infection status (positive versus negative) was determined using the histopathological method. After grams/day, foods were stratified into tertiles of consumption (low, medium, and high). Simple and multiple binary logistic regression models were used in the analysis of odds ratios (ORs) and their respective 95% confidence intervals (CIs), with a 5% significance level. Results The prevalence of H. pylori infection was 44.2% (69/156 patients). Infected individuals had a mean age of 49.6 ± 14.6 years; 40.6% were men, 34.8% were aged 60 years or older, 42.0% were unmarried, 7.2% had higher education, 72.5% were non-white, and 30.4% were obese. In the H. pylori-positive group, 55.1% were alcohol drinkers and 42.0% were smokers. The results of multiple analyses showed that the chance of H. pylori infection was higher among male participants (OR = 2.25; CI = 1.09-4.68) and individuals with obesity (OR = 2.68; CI = 1.10-6.51). Participants with moderate consumption of refined grains (bread, cookies, cakes, breakfast cereal) (OR = 2.41; CI = 1.04-5.62) and fruits (OR = 2.53; CI = 1.08-5.94) were more likely to be infected. Conclusion In this study, male sex, obesity, and the consumption of refined grains and fruits were positively associated with H. pylori infection. Further research is needed to investigate this association and elucidate the underlying mechanisms.

Abstract
Probiotics represent a promising tool to improve metabolic health, including lipid profiles and cholesterol levels. Modulation of the gut microbiome and the endocannabinoidome - two interrelated systems involved in several metabolic processes influenced by probiotics - has been proposed as a potential mechanism of action. This study establishes the impact of probiotics on metabolic health, gut microbiota composition and endocannabinoidome mediators in an animal model of hypercholesterolaemia. Syrian hamsters were fed either a low-fat low-cholesterol or high-fat high-cholesterol (HFHC) diet to induce hypercholesterolaemia and gavaged for 6 weeks with either Lactobacillus acidophilus CL1285, Lactiplantibacillus plantarum CHOL-200 or a combination of the two. Globally, probiotic interventions ameliorated, at least partially, lipid metabolism in HFHC-fed hamsters. The interventions, especially those including L. acidophilus, modified the gut microbiota composition of the small intestine and caecum in ways suggesting reversal of HFHC-induced dysbiosis. Several associations were observed between changes in gut microbiota composition and endocannabinoidome mediators following probiotic interventions and both systems were also associated with improved metabolic health parameters. For instance, potential connexions between the Eubacteriaceae and Deferribacteraceae families, levels of 2‑palmitoylglycerol, 2‑oleoylglycerol, 2‑linoleoylglycerol or 2‑eicosapentaenoylglycerol and improved lipid profiles were found. Altogether, our results suggest a potential crosstalk between gut microbiota and the endocannabinoidome in driving metabolic benefits associated with probiotics, especially those including L. acidophilus, in an animal model of hypercholesterolaemia.

[PMID: 36235867 PMCID: PMC9572631 DOI: 10.3390/nu14194215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Revised: 09/25/2022] [Accepted: 09/30/2022] [Indexed: 11/16/2022] Open
Abstract
Helicobacter pylori (H. Pylori) infection is the main bacterial cause of several gastrointestinal disorders. This study aims to estimate the prevalence of H. pylori infection in a population of Bahraini adults seeking care in gastroenterology clinics in a tertiary care hospital in the Kingdom of Bahrain and examine the association between dietary habits and other factors with H. pylori infection. The study is a hospital-based retrospective, cross-sectional analytical study that included 200 participants. H. pylori infection prevalence among the studied group was 55.5%, and it was significantly higher among participants with a high school education or less (44.1%). Among dietary habits, the mean of frequency of green tea, coffee and honey intake was significantly lower among the H. pylori infected participants compared to their non-infected counterparts. H. pylori infection was significantly higher among participants with vitamin D deficiency (63.6%) compared to participants with normal vitamin D (30%) (p = 0.001) and each unit decrease in serum vitamin D was associated with an increased risk of infection by 1.1 times (OR = 1.1; 95% CI: 1.05, 1.18; p < 0.001). The study revealed that high educational levels, consumption of honey, green tea, and coffee, as well as normal serum vitamin D level, were independent protectors against H. pylori infection. Additional studies are needed to estimate the prevalence and predisposing factors of H. pylori infection in the general population.

Abstract
BACKGROUNDS AND AIMS One of the most important risk factors for Helicobacter pylori (H. pylori) infection is nutrition. Balanced diets with high antioxidant properties may have protective effects against the consequences of this infection. In the current study, we aimed to investigate the association between the dietary antioxidant index and the risk of H. pylori infection among adults. METHODS In a case-control study the dietary intake of patients with H. pylori infection was compared with healthy subjects. The dietary antioxidant index (DAI) was calculated using dietary intakes derived from a validated food frequency questionnaire (FFQ). Demographic information was obtained by a related questionnaire and Physical Activity was measured by International Physical Activity Questionnaire (IPAQ) were used to obtain information. Using logistic regression models, we evaluated the association between the DAI and H. pylori infection risk. The significance level was determined as P < 0.05. RESULTS Finally, dietary data of 148 cases and 302 controls (mean age: 38.72 ± 10.61 (were analyzed. The mean of total DAI was significantly higher in controls (7.67) when compared with H. pylori cases (3.57) (P < 0.001). After adjustment for covariates, participants with less than median DAI values had an increased risk of H. pylori onset (adjusted OR 1.08, 95% CI: 1.02-1.12, P < 0.001). CONCLUSIONS Appropriate intake of nutrient antioxidants may have a role in decreasing the likelihood of H. pylori infection risk.

Abstract
Helicobacter pylori (H. pylori) infection affects more than half of the world’s population, and thus, about 10 to 20% of people with H. pylori suffer from peptic ulcers, which may ultimately lead to gastric cancer. The increase in antibiotic resistance and susceptibility has encouraged the search for new alternative therapies to eradicate this pathogen. Several plant species are essential sources of polyphenols, and these bioactive compounds have demonstrated health-promoting properties, such as the gut microbiota stimulation, inflammation reduction, and bactericidal effect. Therefore, this review aims to discuss the potential effect of plant-based polyphenols against H. pylori and their role in the gut microbiota improvement.

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

Abstract
Helicobacter pylori (H. pylori) infections affect almost half of the world’s population, with gradually increasing incidence in developed countries. Eradication of H. pylori may provide significant benefits to the affected individual by healing a number of gastrointestinal and extra-digestive disorders. But due to increased microbial resistance and lack of patient adherence to the therapy, the eradication rate of H. pylori is below 80% with current pharmacological therapies. The usage of botanicals for their therapeutic purposes and medicinal properties have been increased in last decades. They can be use as alternative H. pylori treatments, especially against drug-resistant strains. Epidemiological studies have revealed that people with lower vegetable and micronutrient intake may be at increased risk of H. pylori infection. We have undertaken a review of clinical trials to evaluate the efficacy of vegetable extracts and micronutrients in patients with H. pylori. Various databases, such as Google Scholar, PubMed, Scopus, Web of Science, and the Cochrane Library, were searched for the articles published in English. A total of 24 clinical studies (15 for vegetable extracts and 9 for micronutrients) were selected to be reviewed and summarized in this article. Vegetable extracts (Broccoli sprouts, curcumin, Burdock complex, and Nigella sativa) and micronutrients (vitamin C and E) were not found to be as effective as single agents in H. pylori eradication, rather their efficacy synergized with conventional pharmacological therapies. Conversely, GutGard was found to be significantly effective as a single agent when compared to placebo control.

Qatar Med J 2021; 2020:45. [PMID: 33623753 PMCID: PMC7878158 DOI: 10.5339/qmj.2020.45] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Accepted: 09/09/2020] [Indexed: 12/25/2022] Open
Abstract
Background: Multiple sclerosis (MS) is an autoimmune disease affecting the central nervous system. Some environmental factors, such as Helicobacter pylori infection (HPI), are likely to be considered a protective factor in MS. Dietary intake may provide exposure to or have protective effects for MS. The present study aimed to determine the relationship between serum anti-H. pylori IgG antibody (HPIA) level and dietary intake in patients with MS referred to the MS Clinic in Rafsanjan city, Iran. Methods: The present case-control study was conducted on 97 patients with MS and 95 controls. The two groups had no significant difference in age and gender (p > 0.05). HPIA was checked, and the food frequency questionnaire was completed in both groups to measure nutritional intake. All data were analyzed by the SPSS 20 software using independent t-test, Chi-Square, Mann–Whitney U test, and correlation. Results: The median serum HPIA level was significantly lower in MS cases than in controls. Furthermore, the median consumption of glutamic acid, arginine, serine, aspartic acid, alanine, proline, and caffeine was significantly lower in MS cases than in controls. A significant positive correlation was found between the levels of linoleic acid, lactose, Ca, molybdenum, galactose, leucine, and valine, and the level of HPIA in controls. Conclusion: Our study results demonstrated that some dietary nutrients had correlations with MS and HPI. Therefore, professionals from multiple disciplines must find which foods contain these dietary nutrients in future studies.

Abstract
OBJECTIVES The aim of this case-control study was to investigate the relationships between carbohydrate consumption, glycemic load (GL), glycemic index (GI), and the risk of Helicobacter pylori infection among adults admitted to an Iranian hospital. METHODS In this case-control study, we recruited 150 participants with H. pylori infection and 302 healthy participants ages 18 to 55. Dietary GI and GL were assessed using a validated 168-item quantitative food frequency questionnaire. Dietary GL was calculated as a function of GI, carbohydrate content, and the frequency of intake of certain foods. RESULTS After adjustment for potential confounders, and comparing the highest tertile with the lowest tertile, a significant direct association was observed between the consumption of carbohydrates (odds ratio [OR] = 2.87; 95% confidence interval [CI], 1.18-6.96; P for trend = 0.017), GI (OR = 3.70; 95% CI, 2.01-6.81; P for trend < 0.001), GL (OR = 3.06; 95% CI, 1.43-6.54; P for trend = 0.001), the consumption of bread and refined-grain products (OR = 4.24; 95% CI, 2.22-8.11; P for trend < 0.001), and the odds of H. pylori infection (OR = 2.22; 95% CI, 1.30-3.79; P for trend = 0.003). CONCLUSIONS Our data suggest that a high dietary GL, high GI, and high consumption of dietary carbohydrates significantly elevate the risk of H. pylori infection. Also, the amount of bread and refined-grain products consumed had a significant positive relationship with H. pylori infection.

Pathways of Gastric Carcinogenesis, Helicobacter pylori Virulence and Interactions with Antioxidant Systems, Vitamin C and Phytochemicals. Int J Mol Sci 2020; 21:ijms21176451.

Abstract
Helicobacter pylori is a class one carcinogen which causes chronic atrophic gastritis, gastric intestinal metaplasia, dysplasia and adenocarcinoma. The mechanisms by which H. pylori interacts with other risk and protective factors, particularly vitamin C in gastric carcinogenesis are complex. Gastric carcinogenesis includes metabolic, environmental, epigenetic, genomic, infective, inflammatory and oncogenic pathways. The molecular classification of gastric cancer subtypes has revolutionized the understanding of gastric carcinogenesis. This includes the tumour microenvironment, germline mutations, and the role of Helicobacter pylori bacteria, Epstein Barr virus and epigenetics in somatic mutations. There is evidence that ascorbic acid, phytochemicals and endogenous antioxidant systems can modify the risk of gastric cancer. Gastric juice ascorbate levels depend on dietary intake of ascorbic acid but can also be decreased by H. pylori infection, H. pylori CagA secretion, tobacco smoking, achlorhydria and chronic atrophic gastritis. Ascorbic acid may be protective against gastric cancer by its antioxidant effect in gastric cytoprotection, regenerating active vitamin E and glutathione, inhibiting endogenous N-nitrosation, reducing toxic effects of ingested nitrosodimethylamines and heterocyclic amines, and preventing H. pylori infection. The effectiveness of such cytoprotection is related to H. pylori strain virulence, particularly CagA expression. The role of vitamin C in epigenetic reprogramming in gastric cancer is still evolving. Other factors in conjunction with vitamin C also play a role in gastric carcinogenesis. Eradication of H. pylori may lead to recovery of vitamin C secretion by gastric epithelium and enable regression of premalignant gastric lesions, thereby interrupting the Correa cascade of gastric carcinogenesis.

Abstract
BACKGROUND Foodstuffs with animal origins, particularly meat, are likely reservoirs of Helicobacter pylori. PURPOSE An existing survey was accompanied to assess phenotypic and genotypic profiles of antibiotic resistance and genotyping of vacA, cagA, cagE, iceA, oipA, and babA2 alleles amongst the H. pylori bacteria recovered from raw meat. METHODS Six-hundred raw meat samples were collected and cultured. H. pylori isolates were tested using disk diffusion and PCR identification of antibiotic resistance genes and genotyping. RESULTS Fifty-two out of 600 (8.66%) raw meat samples were contaminated with H. pylori. Raw ovine meat (13.07%) had the uppermost contamination. H. pylori bacteria displayed the uppermost incidence of resistance toward tetracycline (82.69%), erythromycin (80.76%), trimethoprim (65.38%), levofloxacin (63.46%), and amoxicillin (63.46%). All H. pylori bacteria had at least resistance toward one antibiotic, even though incidence of resistance toward more than eight antibiotics was 28.84%. Total distribution of rdxA, pbp1A, gyrA, and cla antibiotic resistance genes were 59.61%, 51.92%, 69.23%, and 65.38%, respectively. VacA s1a (84.61%), s2 (76.92%), m1a (50%), m2 (39.13%), iceA1 (38.46%), and cagA (55.76%) were the most generally perceived alleles. S1am1a (63.46%), s2m1a (53.84%), s1am2 (51.92%), and s2m2 (42.30%) were the most generally perceived genotyping patterns. Frequency of cagA-, oipA-, and babA2- genotypes were 44.23%, 73.07%, and 80.76%, respectively. A total of 196 combined genotyping patterns were also perceived. CONCLUSION The role of raw meat, particularly ovine meat, in transmission of virulent and resistant H. pylori bacteria was determined. VacA and cagA genotypes had the higher incidence. CagE-, babA2-, and oipA- H. pylori bacteria had the higher distribution. Supplementary surveys are compulsory to originate momentous relations between distribution of genotypes, antibiotic resistance, and antibiotic resistance genes.

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
Background Foods with animal origins and particularly milk play a considerable role in transmission of Helicobacter pylori. The current study was performed to assess phenotypic characters of antibiotic resistance and genotyping pattern of vacA, cagA, iceA, oipA and babA2 alleles amongst the H. pylori strains isolated from raw milk. Methods Six-hundred and thirty raw milk samples were collected and cultured on Wilkins Chalgren anaerobe media. Antibiotic resistance and genotyping patterns were studied using disk diffusion and PCR, respectively. Results Sixty-seven out of 630 (10.63%) raw milk samples were positive for H. pylori. Ovine raw milk (17.27%) samples had the highest prevalence of H. pylori, while camel (5.00%) had the lowest. H. pylori strains harbored the highest prevalence of resistance against ampicillin (82.08%), tetracycline (76.11%), amoxicillin (74.62%), metronidazole (65.67%) and erythromycin (53.73%). Prevalence of resistance against more than 10 types of antibiotics was 17.91%. VacA s1a (83.58%), m1a (80.59%), s2 (77.61%) and m2 (68.65%), cagA (73.13%) and babA2 (44.77%) were the most commonly detected genotypes. We found that S1am1a (56.71%), s2m1a (56.71%), s1 am2 (43.28%) and s2 m2 (43.28%) were the most commonly detected genotyping pattern. Frequency of cagA-, oipA- and babA2- genotypes were 26.86%, 62.68% and 55.22%, respectively. We found that S1a/cagA+/iceA1/oipA-/babA2- (28.35%), m1a/cagA+/iceA1/oipA-/babA2- (28.35%) and s2/cagA+/iceA1/oipA-/babA2- (26.86%) were the most commonly detected combined genotyping pattern. Conclusions Simultaneous presence of vacA, cagA, iceA, oipA and babA2 genotypes in antibiotic resistant H. pylori strains indicates important public health issue regarding the consumption of raw milk. However, additional researches are required to find molecular genetic homology and other epidemiological aspects of H. pylori in milk.

Abstract
Helicobacter pylori is the main pathogen that induces chronic gastritis, peptic ulcers, atrophic gastritis, and other gastric disorders, and it is classified as a group I carcinogen. To eradicate H. pylori infection, triple therapy consisting of two antibiotics and a proton pump inhibitor is the most widely recommended first-line therapeutic strategy. Antimicrobial resistance to antibiotics contained in triple therapy could lead to therapeutic regimen failures. Recent studies showed that many natural products, including fruits, vegetables, spices, and medicinal plants, possess inhibitory effects on H. pylori, indicating their potential to be alternatives to prevent and manage H. pylori infection. This review summarizes the effects of natural products on H. pylori infection and highlights the mechanisms of action.

Abstract
BACKGROUND To examine the association between dietary habits and Helicobacter pylori (H. pylori) infection among patients at a tertiary healthcare center in Lebanon. METHODS This cross-sectional study was conducted on 294 patients in 2016, at a hospital in Northern Lebanon. Participants were interviewed using a structured questionnaire to collect information on socio-demographic and lifestyle characteristics; dietary habits were ascertained via a short food frequency questionnaire (FFQ). H. pylori status (positive vs. negative) was determined after upper GI endoscopy where gastric biopsy specimens from the antrum, body, and fundus region were collected and then sent for pathology analysis. Multivariable logistic regression was conducted to identify the association between socio-demographic, lifestyle, dietary and other health-related variables with H pylori infection. RESULTS The prevalence of H. pylori infection was found to be 52.4% in this sample. Results of the multivariable analysis showed that H. pylori infection risk was higher among participants with a university education or above (OR = 2.74; CI = 1.17-6.44), those with a history of peptic ulcers (OR = 3.80; CI = 1.80-8.01), gastric adenocarcinoma (OR = 3.99; CI = 1.35-11.83) and vitamin D level below normal (OR = 29.14; CI = 11.77-72.13). In contrast, hyperglycemia was protective against H. pylori (OR = 0.18; CI = 0.03-0.89). No relationship between dietary habits and H. pylori infection was found in the adjusted analysis. CONCLUSIONS Socio-demographic and clinical variables are found to be associated with H. pylori, but not with dietary factors. Further studies are needed to investigate the effect of diet on H. pylori risk.

Abstract
INTRODUCTION Helicobacter pylori infections affect almost 50% of the world population, constituting a risk factor for benign and malignant gastrointestinal diseases. The increased resistance to antibiotic treatment against this infection represents a dilemma in the search of other therapeutic alternatives. OBJECTIVE To determine the efficacy of the use of vitaminC and E supplements concomitantly to antibiotic treatment against H. pylori infections. METHODS We performed a systematic review on the MedLine (PubMed), Embase and Cochrane Central Register of Clinical Trials (CENTRAL) databases, searching for studies evaluating the efficacy of vitaminC and/or E supplements in the antibiotic treatment of H. pylori infections. The primary outcome was eradication of the infection. The secondary outcome was the adverse effects. The meta-analysis was conducted using the random effects method. RESULTS Ten studies were included and analyzed in two groups. The first group, which was comprised by 973patients, compared the use of supplementation with vitaminC and E, showing that, without discriminating the number of antibiotics used, there was no relationship with the eradication of the infection (OR: 1.98 [95%CI: 0.92-4.29] P=.08). The triple or quadruple antibiotic therapy had no effect on eradication rates either (OR 1.80 [95%CI: 0.64-5.08] P=.26 and OR: 2.84 [95%CI: 0.51-15.56] P=.22, respectively). No effect on the eradication rates was observed either in the group that only assessed the use of vitaminC, comprised by 702patients (OR: 1.17 [95%CI: 0.58-2.31] P=.65). Only four studies reported adverse effects, the most common one being nausea. CONCLUSIONS Supplementation with vitaminC and E in the antibiotic treatment against H. pylori has no effect. However, the reviewed studies had several biases and differences in the dosage of the supplements and antibiotics administered.

Abstract
The aim of this study was to assess the association between some dietary factors and prevalence of H. pylori infection or strain virulence in 294 adult asymptomatic blood donors. Methods. Seroprevalence was evaluated using ELISA. Logistic regression was used. Results. Anti-H. pylori IgG prevalence was 72.4%, and CagA IgG seroprevalence was 49.3%. In the multivariate analyses, the frequent (>5 days per week) honey consumption was associated with both reduced H. pylori seroprevalence OR, 0.68 with 95% confidence interval (CI), 0.473-0.967 and reduced CagA IgG seroprevalence OR, 0.65 with 95% CI, 0.486-0859. Frequent (>5 days per week) yoghurt consumption also was associated with lower H. pylori virulence of the strains (CagA IgG OR, 0.56 with 95% CI, 0.341-0.921). Smoking and consumption of the other dietary factors resulted in no significant differences in the prevalence of H. pylori IgG and CagA IgG within the subject groups. Conclusion. To the best of our knowledge, this is the first report revealing reverse associations between honey or yoghurt consumption and CagA IgG prevalence as well as between frequent honey consumption and lower prevalence of the H. pylori infection. Regular honey and yoghurt consumption can be of value as a supplement in the control of H. pylori therapy.

Abstract
Active ingredients in plant protection products are subject to rigorous safety assessment during their development, including assessment of genotoxicity. Plant protection products are used for agriculture in multiple regions and for the registration of active ingredients it is necessary to satisfy the data requirements of these different regions. There are no overarching global agreements on which genotoxicity studies need to be conducted to satisfy the majority of regulatory authorities. The implementation of new OECD guidelines for the in vitro micronucleus, transgenic rodent somatic and germ cell gene mutation and in vivo comet assays, as well as the revision of a number of other OECD test guidelines has resulted in some changes to data requirements. This review describes the genotoxicity data requirements for chemical active ingredients as well as biologicals, microbials, ground water metabolites, metabolites, and impurities in a number of regions. Similarities and differences are highlighted. Environ. Mol. Mutagen. 58:325-344, 2017. © 2017 Wiley Periodicals, Inc.

Abstract
Background: To date, there is still inconclusive evidence on the extra-gastric manifestations of Helicobacter pylori (H.pylori) infection. This study aimed to determine whether there is an association between H.pylori infection with metabolic syndrome and dietary habits among medical undergraduate students in south-eastern of Iran, Zahedan. Materials and Methods: This cross-sectional study was done among 363 undergraduate students in Zahedan University of Medical Sciences during spring 2014. All subjects completed a questionnaire including demographic factors and dietary habits. Serum H. pylori-specific IgG antibodies, total cholesterol (TC), triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and fasting blood sugar (FBS) levels were measured after an overnight fast. Results: The seroprevalence of H. pylori infection was 45.7%. H. pylori-positive subjects had lower mean levels of TC and TG and higher levels of HDL-C compared to H. pylori-negative subjects. In addition, lower levels of LDL-C (P = 0.044) and FBS (P = 0.05) were observed among subjects with positive H pylori infection. Only rare consumption of raw vegetables (odds ratio [OR] =3.74, 95% confidence interval [CI] =1.37–5.24) as well as higher levels of FBS (OR = 1.031, 95% CI = 1.001–1.99) were significantly associated with higher odds of H. pylori infection in both the univariate and multiple logistic regression analysis. Conclusion: In a small population of young students in southeastern of Iran, H. pylori infection was associated with low consumption of raw vegetables and higher serum blood glucose.

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.
