[PMID: 39182294 DOI: 10.1016/j.jhazmat.2024.135584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2024] [Revised: 08/14/2024] [Accepted: 08/18/2024] [Indexed: 08/27/2024]
Abstract
BACKGROUND Helicobacter pylori infection (HPI) is extremely common in the world, particularly in less developed areas, but the primary causes of childhood HPI are unspecified. OBJECTIVES To determine the influences of exposure to home environmental factors (HEFs), outdoor air pollutants (OAPs), and parental stress (PS), as well as their interactions on children's HPI. METHODS We implemented a retrospective cohort study with 8689 preschoolers from nine districts at Changsha, China, was conducted using questionnaires to collect data of health and HEFs. Temperature and OAPs data were collected from ten and eight monitoring stations, individually. Temperature and OAPs exposures were calculated for all home addresses using the inversed distance weighted (IDW) model. Multiple logistic regression analysis was carried out to determine the separate and combined impacts of HEFs, OAPs, and PS on HPI. RESULTS Children's HPI was significantly associated with exposure to moisture-specific indoor allergens in one-year preceding conception, gestation, and first year, smoke-specific air pollution throughout life, and plant-specific allergens in previous year. Outdoor exposures to CO in the 7th-9th month before conception, as well as PM2.5 in the second trimester and previous year, were associated with HPI, with ORs (95 % CIs) of 1.22 (1.05-1.41), 1.23 (1.03-1.46), and 1.33 (1.14-1.55). Parents' socioeconomic and psychological stress indicators were positively related to HPI. High socioeconomic indicators and psychological stresses increased the roles of indoor renovation and moisture indicators as well as outdoor SO2, PM2.5 and O3 on children's HPI over their entire lives. Parental psychological stress interacts with indoor renovation-specific air pollution, moisture- and plant-specific allergens, as well as outdoor traffic-related air pollution on HPI, during a critical time window in early life. CONCLUSIONS Indoor and outdoor air pollutants, as well as allergens, separately and interactively exert important effects on childhood HPI, lending support to the "(pre-) fetal origin of HPI" hypothesis.

Abstract
BACKGROUND Limited studies have reported the association between dietary patterns and Helicobacter pylori (H. pylori) infection in Sabah. OBJECTIVE The purpose of this study was to assess the association between dietary pattern and H. pylori infection among patients aged 18 years and above that went for first esophagogastroduodenoscopy (OGDS) in 2021 at Queen Elizabeth Hospital (QEH), Kota Kinabalu. METHODS Dietary intake of positive H. pylori was compared with healthy subjects by using questionnaire adapted from Malaysian Adult Nutrition Survey (MANS) 2014. Using logistic regression models, we evaluated the association between dietary pattern and H. pylori infection risk. FINDINGS Our finding identified four dietary patterns, namely "high carbohydrate pattern", "high fiber pattern", "high fat/cholesterol pattern" and "high salt pattern". After adjustment for potential confounders, the highest quartile of "high salt pattern" showed greater odds of H. pylori infection (OR = 1.26; 95% Cl: 1.032-1.459; P = 0.045) than lowest quartile, while highest quartile of "high fiber pattern" demonstrated lower odd of the infection (OR = 0.69; 95% Cl: 0.537-0.829; P = 0.008) than those in lowest quartile. If compared with Recommended Nutrient Intake (RNI) 2017, positive H. pylori consumed high carbohydrates and sodium with insufficient fiber intake. CONCLUSION To conclude, "high fiber pattern" lowers the risk of H. pylori infection while "high salt pattern" increases the infection risk. Our study also highlighted the importance of nutrient intake within daily allowances.

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), the most common infection of childhood, results in life-threatening complications during adulthood if left untreated. Most of these complications are related to H. pylori-induced chronic inflammation. The dysbiosis caused by H. pylori is not limited to the gastric microenvironment, but it affects the entire gastrointestinal tract. Eradication of H. pylori has recently become a real challenge for clinicians due to both the persistent increase in antibiotic resistance worldwide and the wide spectrum of side effects associated with the eradication regimens resulting; therefore, there is an urgent need for more effective and less noxious treatment options. Thus, probiotics might be a promising choice in both adults and children with H. pylori infection since their role in improving the eradication rate of this infection has been proved in multiple studies. The positive effects of probiotics might be explained by their abilities to produce antimicrobial compounds and antioxidants, alter local gastric pH, and subsequently decrease H. pylori colonization and adherence to gastric epithelial cells. Nevertheless, if used alone probiotics do not considerably increase the eradication rate.

Abstract
INTRODUCTION American Indian and Alaska Native (AI/AN) populations have higher gastric cancer rates than the general US population. This study provides a comprehensive overview of incidence rates among AI/AN persons during 2005-2016 compared with non-Hispanic whites (whites). METHODS Population-based cancer registry data for 2005-2016 were linked with the Indian Health Service patient registration databases to address racial misclassification. Age-adjusted gastric cancer incidence rates were expressed per 100,000 per year. Incidence and trend analyses were restricted to purchased/referred care delivery area counties in 6 geographic regions, comparing gastric cancer incidence rates for AI/AN vs white populations in the United States. RESULTS Gastric cancer rates were higher in the AI/AN compared with white populations in nearly every US region. Incidence rates for central/distal portions of the stomach were higher in AI/AN individuals compared with whites. Rates of later stage gastric cancer were higher in AI/AN populations overall and in every region except the Pacific Coast and East. Incidence rates decreased significantly over time in both populations. Declining rates in the AI/AN populations were driven by changes in the Pacific Coast and Northern Plains regions. DISCUSSION AI/AN populations have a disproportionately high incidence of gastric cancer, especially in Alaska. High incidence in the central/distal portions of the stomach among AI/AN populations likely reflects a high prevalence of Helicobacter pylori infection in these populations. These data can be used to develop interventions to reduce risk factors and improve access to health services among AI/AN people at high risk for gastric cancer.

Abstract
Aim To assess the effect of Lactobacillus supplementation on Helicobacter pylori eradication rates and side effects of the triple therapy. Methods PubMed, Embase, Web of Science and Cochrane Library were searched for articles published up to July, 2019. Review Manager 5.3 and Stata 12.0 were used for statistical analyses. Results The initial database search resulted in 852 articles. Through exclusion and screening, 11 randomized controlled trials involving a total of 724 patients were finally included in this meta-analysis. The H. pylori elimination rate in the Lactobacillus supplement group was significantly higher than that in the control group (RR 1.16, 95% CI 1.08–1.25, P<0.0001). Subgroup analysis showed that the eradication rates were significantly enhanced in both adults and children group, and no significant difference was detected between Asia and Europe group. In addition, sub-analysis based on duration of Lactobacillus supplementation showed the pooled RRs in the long-term and short-term groups were 1.17 (95%CI 1.06–1.30) and 1.16 (95% CI 1.04–1.30), respectively. Regarding the Lactobacillus strains, the pooled RR was 1.33 (95% CI 1.10–1.62) in the L. casei group, 1.18 (95% CI 1.03–1.34) in the L. reuteri group while 1.02 (95% CI 0.87–1.21) in the Lactobacillus GG group. As for the total side effects, Lactobacillus supplementation significantly reduced the incidence of taste disturbance (RR = 0.36, 95% CI 0.17–0.74, P = 0.005). Conclusions Lactobacillus supplementation during the treatment of Helicobacter pylori infection can effectively improve the eradication rates, and reduce the incidence of therapy-related taste disturbance.

Abstract
Probiotics are defined as, "Live microorganisms that, when administered in adequate amounts, confer a health benefit on the host", and have various effects including inhibitory capabilities on pathogens, stimulation of organ functions and activation of immune responses in the human. Probiotics were reported to inhibit Helicobacter pylori not only in vitro, but also in vivo studies. The mechanisms by which probiotics inhibit H. pylori infection include competition for nutrients, production of bactericidal substances, competitive inhibition of adherence and stimulation of host functions and immunity. In addition, probiotics are clinically used for eradication therapy of H. pylori infection, and the effects of probiotics as single treatment and combination use with other drugs including proton pump inhibitors and antibiotics against H. pylori are reported. It has been testified that probiotics increase the eradication rate and prevent adverse events including diarrhea, nausea, vomiting and taste disorder. In the Maastrich V/Florence Consensus Report 2017, it was stated that some probiotics may have a beneficial effect on H. pylori eradication and are effective in reducing side effects of eradication therapy, but more research is needed to answer several questions concerning the mechanisms of probiotics action. In addition, strain specificity, dosages and duration times of probiotics used for H. pylori eradication therapy need to be clarified in future studies.

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.

[PMID: 27723762 PMCID: PMC5056761 DOI: 10.1371/journal.pone.0163743] [Citation(s) in RCA: 89] [Impact Index Per Article: 11.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2016] [Accepted: 09/13/2016] [Indexed: 02/06/2023] Open
Abstract
Background Traditional Helicobacter pylori (H. pylori) eradication therapies have shown efficacies below 80% in several studies, and their use has been accompanied by antibiotic-related side effects. Some recent studies have reported that supplementing standard therapies with probiotics can improve the efficacy and tolerability of Helicobacter pylori eradication therapy. Objective To assess the effects of probiotic supplementation on the eradication rates and therapy-related adverse event rates of anti-Helicobacter pylori regimens. Methods We searched PubMed, Medline, the Cochrane Central Registry of Controlled Trials and the Chinese Biomedical Database for eligible randomized controlled trials published through July, 2015. Review Manager 5.3 was used for all statistical analyses. Results Thirteen randomized controlled trials involving a total of 2306 patients were included in our analysis. Intent-to-treat (ITT) analysis performed using a fixed-effects model (test for heterogeneity I2 = 45%) showed that the pooled relative risk (RR) of eradication was significantly higher in the probiotic supplementation group than in the control group [RR 1.15, 95% confidence interval (CI): 1.10–1.20, P<0.00001]. The incidence of total antibiotic-related side effects was lower in the probiotic supplementation group than in the control group, and the pooled RR (studies n = 9) was 0.71 (95% CI: 0.54–0.94, P = 0.02), as determined using a random-effects model (heterogeneity test I2 = 59%). Certain adverse events, such as nausea and vomiting (RR = 0.58, 95% CI 0.35–0.95, P = 0.03), diarrhea (RR = 0.51, 95% CI: 0.31–0.84, P = 0.008) and constipation (RR = 0.47, 95% CI: 0.28–0.80, P = 0.005), were reported at lower rates in the probiotic supplementation group than in the control group. Subgroup analysis showed that eradication rates were significantly improved in both adults (RR = 1.14, 95% CI: 1.09–1.19, P<0.00001) and children (RR = 1.24, 95% CI: 1.05–1.47, P = 0.01) in the probiotic supplementation group and that no regional differences between Europe (RR = 1.17, 95% CI: 1.09–1.24, P<0.00001) and Asia were present (RR = 1.14, 95% CI: 1.06–1.22, P = 0.0002). However, the total adverse event rate was not decreased in the adult group (RR = 0.80, 95% CI: 0.61–1.04, P = 0.1) or the Asian group (RR = 0.68, 95% CI: 0.39–1.18, P = 0.17). Subgroup analyses examining therapy regimens and treatment durations showed that probiotic supplementation increased eradication rates in the triple-therapy (RR = 1.18, 95% CI: 1.12–1.25, P<0.00001), seven-day treatment (RR = 1.21, 95% CI: 1.12–1.31, P<0.00001) and fourteen-day treatment (RR = 1.13, 95% CI: 1.06–1.20, P = 0.0002) groups. The incidence of antibiotic-related side effects was significantly reduced in all groups, with the exception of the quadruple-therapy subgroup (RR = 1.13, 95% CI: 0.60–2.13, P = 0.07) and the fourteen-day therapy subgroup (RR = 0.96, 95% CI 0.61–1.51, P = 0.86). Supplementation with Lactobacillus alone (RR = 1.24, 95% CI: 1.12–1.38, P<0.0001) or multi-strain probiotics (RR = 1.12, 95% CI 1.07–1.18, P<0.00001) was effective at improving H. pylori eradication rates. However, supplementation with Lactobacillus alone did not significantly decrease the overall incidence of side effects (RR = 0.61, 95% CI: 0.11–3.51, P = 0.58). Our study also showed that probiotic supplementation before, during or after H. pylori eradication therapy improved eradication rates, regardless of supplementation duration. Furthermore, probiotic supplementation during H. pylori treatment reduced the incidence of side effects. Conclusion Probiotic supplementation during anti-Helicobacter pylori treatment may be effective for improving H. pylori eradication rates, minimizing the incidence of therapy-related adverse events and alleviating most disease-related clinical symptoms. However, our results should be interpreted with caution because of the presence of heterogeneity across the trials included in this analysis.

Abstract
OBJECTIVE Gastric colonization by Helicobacter pylori is linked to a host of diseases, but eradication rates have declined in recent years. Some experimental studies suggest that probiotics may inhibit growth of H. pylori. This investigation was conducted to assess the impact of probiotics on both efficacy and tolerability of triple therapy to eradicate H. pylori. METHODS PubMed, Web of Science, and the Cochrane Collaboration were searched for relevant articles published through August 31, 2014. All analytics relied on commercially available software (Stata 11). RESULTS Twenty-three studies (N = 3900) qualified for meta-analysis. Pooled H. pylori eradication rates for triple therapy used alone and with added probiotics were 1464/2026 (72.26%; 95% CI, 67.66%-74.13) and 1513/1874 (80.74%; 95% CI, 74.68%-82.76%), respectively (odds ratio [OR] = 0.58; 95% CI, 0.50-0.68). Loss of appetite was similar in both groups (OR = 0.94; 95% CI, 0.61-1.45), but most adverse events (nausea, diarrhea, epigastric pain, vomiting, taste distortion, and skin rash) were mitigated through addition of probiotics. Publication bias was not evident, as indicated by Begg's and Egger's tests. CONCLUSIONS Probiotics may improve the efficacy of triple therapy in eradicating gastric H. pylori and alleviate most treatment-related adverse events.

Abstract
Background and Aim. Helicobacter pylori (HP) and diet are both risk factors for gastric cancer. The aim of this study was to evaluate the Helicobacter pylori infection and dietary habits common in Khuzestan province. Methods. This cross-sectional study was conducted in 2011–2013 on 374 patients. Participants were interviewed using a food frequency questionnaire and tissue sample of the antrum was sent for pathology lab. The histopathological major variables were graded on a scale of 3 (mild, moderate, and severe) and data analyzed using nonparametric tests. Results. In this study, of 160 patients (43%) that were determined, 8.1 percent had severe contamination. Among dietary patterns, relationship between energy intake and carbohydrate with H. pylori was significant. A direct association was found between mean daily intakes of sausage (P = 0.001) and burgers (P < 0.05) with HP infection. Low intake of fresh vegetables and fruits was the most significant risk factors (P < 0.05). Conclusion. There is a possibility that some dietary factors such as consumption of fast foods and low intake of fresh vegetables may increase the chance of HP and severity of this infection.

Abstract
INTRODUCTION There is a high prevalence worldwide of Helicobacter pylori (Hp) infection associated with gastritis and extending to gastric cancer. Reports have suggested that alcohol has antibacterial action and that its concentration and the amount consumed reduce the risk for Hp infection. In contrast, different studies suggest that tobacco and coffee consumption are risk factors for Hp infection, but their results are controversial. AIMS To compare the frequency of alcohol consumption in patients infected by Hp with that of non-infected subjects and, as a secondary aim, to compare the association of smoking and coffee consumption with Hp infection. MATERIAL AND METHODS A case-control study was conducted on Sinaloa State workers that underwent endoscopy and the Hp serology test. Cases were defined as patients with a positive Hp serology test or a positive biopsy with the rapid urease test. Alcohol consumption was categorized as: no consumption, low-risk, and at-risk. The sample included 269 subjects per group. Odds ratio (OR) and 95% confidence interval (CI) were calculated. RESULTS In both groups, the mean age of the subjects was 45.7 (SD: 9) years (P=.99), 139 of the subjects were women (51.7%) and 130 were men (48.3%); alcohol consumption was present in 108 (40.1%) and 85 (31.6%) of the cases and controls, respectively (P=.039), OR 1.45 (95%CI 1.019-2.069). The quantity of grams of alcohol in subjects with at-risk consumption was significant; However, there were no significant differences in relation to smoking and coffee consumption between the groups. CONCLUSIONS An association between alcohol consumption and HP infection was observed and no relation with HP infection was found with respect to smoking and coffee consumption.

Abstract
Background/Aims Atrophic gastritis (AG) and intestinal metaplasia (IM) are premalignant gastric lesions. The aims of this study were to evaluate the prevalence of endoscopic AG and IM and to document the risk factors for these lesions. Methods In total, 4,023 subjects were enrolled at eight hospitals in Korea. AG and IM were diagnosed by endoscopy. Helicobacter pylori immunoglobulin G antibodies were measured. Results The prevalences of endoscopic AG and IM were 40.7% and 12.5%. In a multivariate analysis, the risk factors for AG were age groups of 40 to 59 years and >60 years, male sex, positive H. pylori serology, IM, and education below the college level (odds ratio [OR], 2.55, 5.00, 1.38, 1.41, 4.29, and 1.35, respectively). The risk factors for IM were age groups of 40 to 59 years and >60 years, male sex, positive H. pylori serology, AG, having relatives with gastric cancer, education below the college level and consumption of dairy products (OR, 3.16, 3.25, 1.88, 2.17, 3.68, 1.48, 1.47, and 1.40, respectively). Conclusions A nationwide survey regarding the prevalence of endoscopic AG and IM and their risk factors in Korea supports the hypothesis that endoscopic diagnosis of these premalignant lesions could be helpful to describe a group at high risk for gastric cancer.

Abstract
Helicobacter pylori (HP) is associated with chronic gastritis and gastric cancer, and more than half of the world's population is chronically infected. The aim of this retrospective study was to investigate whether an irregular meal pattern is associated with increased risk of gastritis and HP infection. The study involved 323 subjects, divided into three groups as follows: subjects with HP infection and gastritis, subjects with gastritis, and a control group. Subjects were interviewed on eating habits and meal timing. Multivariate logistic regression was used to compare groups. Adjusted odds ratios (OR) were derived controlling for gender, age, stress, and probiotic consumption. Subjects who deviated from their regular meals by 2 hours or more had a significantly higher incidence of HP infection with gastritis (adjusted OR = 13.3; 95% CI 5.3–33.3; P < 0.001) and gastritis (adjusted OR = 6.1; 95% CI 2.5–15.0; P < 0.001). Subjects who deviated their meals by 2 hours or more, twice or more per week, had an adjusted OR of 6.3 and 3.5 of acquiring HP infection with gastritis (95% CI 2.6–15.2; P < 0.001) and gastritis (95% CI 1.5–8.5; P < 0.001), respectively. Frequent deviation in meal timing over a prolonged period appears associated with increased risk of developing HP infection and gastritis.

Abstract
Objective: To review the literature on the role of probiotics as adjunctive therapy in the treatment of Helicobacter pylori infections. Data Sources: Literature was accessed through MEDLINE (1966-March 2011) using the terms H. pylori, probiotic, Lactobacillus, Bifidobacterium, Saccharomyces, Bacillus clausii, and Propionibacterium. Article references were hand-searched for additional relevant articles and abstracts. Study Selection and Data Extraction: All English-language articles published in full were evaluated. Randomized, double-blind, placebo-controlled trials assessing the use of probiotics combined with standard eradication therapy of H. pylori infection in adults were included in the review. Data Synthesis: Various probiotics, including Lactobacillus spp., Saccharomyces spp., Bifidobacterium spp., and B. clausii, reduce adverse effects such as nausea, taste disturbance, diarrhea, and epigastric pain, and increase tolerability of H. pylori eradication therapy. Based on the studies reviewed, probiotics do not affect H. pylori eradication rates. Conclusions: Probiotics may be beneficial in reducing adverse effects and increasing tolerability of H. pylori eradication regimens. They may especially be helpful in patients with recurrent H. pylori infection and a history of gastrointestinal adverse effects with antibiotics. Pharmacists can play an important role in educating patients regarding probiotic use during H. pylori eradication therapy.

Abstract
Although Helicobacter pylori infection is both a common and a serious bacterial infection, antimicrobial therapies have rarely been optimized, are prescribed empirically, and provide inferior results compared with antimicrobial therapies for other common infectious diseases. The effectiveness of many of the frequently recommended H. pylori infection treatment regimens has been increasingly compromised by antimicrobial resistance. Regional data on the susceptibility of strains of H. pylori to available antimicrobials are sorely needed. Noninvasive molecular methods are possible to assess clarithromycin susceptibility in isolates obtained from stool specimens. As a general rule, clinicians should prescribe therapeutic regimens that have a ≥90% or, preferably, ≥95% eradication rate locally. If no available regimen can achieve a ≥90% eradication rate, clinicians should use the most effective regimen(s) available locally. Eradication of infection should always be confirmed after treatment in order to provide feedback regarding local effectiveness and an early warning of increasing resistance. In most regions of the world, four-drug treatment regimens, including a PPI plus three antimicrobials (clarithromycin, metronidazole/tinidazole and amoxicillin), or a PPI plus a bismuth plus tetracycline and metronidazole provide the best results. Standard triple therapy (a PPI, amoxicillin and clarithromycin) should now be avoided owing to increasing resistance to this treatment.

Abstract
INTRODUCTION The outcome of Helicobacter pylori (Hp) eradication therapy from the aspect of prevention of chest pain recurrence is still uncertain. The aim of this study was to assess the influence of Hp eradication therapy on the risk of hospitalization due to acute coronary syndrome. MATERIAL AND METHODS The analysis was carried out in 63 consecutive patients with recurrent retrosternal symptoms: 28 (44%) with significant coronary artery narrowing in coronarography not qualified for revascularization by an invasive cardiologist, and 35 (56%) with no obstructive coronary artery lesions. In 33 (52%) of the patients, Hp infection was found and standard eradication therapy with omeprazole (2 × 20 mg), amoxicillin (2 × 1 g) and metronidazole (2 × 500 mg) was recommended. The mean follow-up period was 977 ±249 days. RESULTS Chest pain requiring hospitalization because of unstable angina within the follow-up period was observed in 9 (27%) of the Hp-infected individuals and in 15 (50%) subjects in whom a urease test and histology did not confirm this infection (p = 0.055). The recommendation of Hp-eradication treatment was a significant factor prolonging the hospitalization-free period, both in the two Kaplan-Meier curve analyses (Cox's F test = 1.96; p = 0.049) and the Cox proportional hazard model (beta = -1.18; p = 0.045), but was weaker than the effect of the non-obstructive coronary angiogram (beta = -1.45; p = 0.03). CONCLUSIONS The recommendation of Hp-eradication therapy may prolong the hospitalization-free period for patients with recurrent chest pain.

Abstract
With the progressive elimination of dietary protein-energy deficits, deficiencies of micronutrients are emerging as the limiting factors in ensuring children's optimal health. Data from several countries in Asia and Latin America indicate that deficiencies of vitamin C and zinc continue to be at alarming levels. This article reviews the roles of vitamin C and zinc in supporting children's growth and development, with a particular focus on the complementary roles they play in supporting immune functions and combating infections. The contemporary relevance of vitamin C and zinc deficiency in the Asian and Latin American regions, both undergoing a rapid nutritional transition, are also discussed. Overall, there is increasing evidence that deficiency of vitamin C and zinc adversely affects the physical and mental growth of children and can impair their immune defences. Nutrition should be the main vehicle for providing these essential nutrients; however, supplementation can represent a valid support method, especially in developing regions.
