One of the problems of renal disease patients, especially patients undergoing dialysis, is gastrointestinal complications caused by Helicobacter pylori infection. H. pylori has still high prevalence in most populations. It is estimated that about half of the world population is infected with this infection and it can change levels of most micronutrients such as magnesium. Different studies demonstrate that H. pylori may affect the metabolism of magnesium in renal failure. The present paper investigated the association of serum magnesium level with H. pylori infection. Nevertheless, it should be more evaluated by researchers and still many studies are necessary to confirm this issue.

The high prevalence of H. pylori and diseases caused by this infection determine the relevance of discussing the problems of its diagnosis and treatment on the eve of the emergence of new international and domestic agreements. Studies published in recent years, including articles on the materials of the European Registry on the management of Helicobacter pylori infection (Hp-EuReg), provide a rich background for the analysis of errors in diagnosis and treatment of this infection, and the development of approaches to optimize clinical practice.

SUMMARYWe examined the prevalence, correlates and trends of H. pylori infection in Israel using residual sera obtained in 2007–2008 from 1466 Jewish subjects aged 0–77 years and 897 Arabs aged 0–19 years, and in 2000–2001 from 627 Jewish and 575 Arab subjects aged 0–19 years. H. pylori IgG antibodies were measured by ELISA. The age-adjusted H. pylori seroprevalence was 45·2% in Jewish participants. Seropositivity increased with age, reaching 60% at age ⩾50 years and ranged from 24·3% in subjects originating from North America/Western Europe/Australia, to 63·2% in those from Asia/Africa/South America. Among Arabs, H. pylori seroprevalence was 42·1% and reached 65% in adolescents. There was no significant change in seroprevalence between 2000–2001 and 2007–2008. High prevalence of H. pylori was found in Arabs, and in Jews originating from countries of high H. pylori endemicity. These findings are characteristic of countries of diverse ethnic structure and recent immigration.

Helicobacter pylori infection is commonly treated with a combination of antibiotics and proton pump inhibitors. However, since H. pylori is becoming increasingly resistant to standard antibiotic regimens, novel treatment strategies are needed. Previous studies have demonstrated that black and red berries may have antibacterial properties. Therefore, we analyzed the antibacterial effects of black and red raspberries and blackberries on H. pylori. Freeze-dried powders and organic extracts from black and red raspberries and blackberries were prepared, and high-performance liquid chromatography was used to measure the concentrations of anthocyanins, which are considered the major active ingredients. To monitor antibiotic effects of the berry preparations on H. pylori, a high-throughput metabolic growth assay based on the Biolog system was developed and validated with the antibiotic metronidazole. Biocompatibility was analyzed using human gastric organoids. All berry preparations tested had significant bactericidal effects in vitro, with MIC90 values ranging from 0.49 to 4.17%. Antimicrobial activity was higher for extracts than powders and appeared to be independent of the anthocyanin concentration. Importantly, human gastric epithelial cell viability was not negatively impacted by black raspberry extract applied at the concentration required for complete bacterial growth inhibition. Our data suggest that black and red raspberry and blackberry extracts may have potential applications in the treatment and prevention of H. pylori infection but differ widely in their MICs. Moreover, we demonstrate that the Biolog metabolic assay is suitable for high-throughput antimicrobial susceptibility screening of H. pylori.

Helicobacter pylori infection concerns half of the world’s population, mainly in developing countries. It causes several gastrodudenal pathologies such as gastritis, ulcer and gastric adenocarcinoma. The aim of our study was to determine the prevalence of H.pylori infection and to assess the impact of different epidemiological factors as well as principal gastric diseases associ-ated to this infection. We underwent a prospective study during 18 months (month 2016-month 2017) which implicated 201 symptomatic patients for gastric fiboptic endoscopy at the level of Sidi Bel Abbes University hospital. We collected patients’ biopsies to perform a histological study and H. pylori culture. H. pylori identification was carried out based on bacteriological and biochemical analysis. The middle age of our population was (47.29 ±15.97ans) and the sex-ratio =0,8. The global prevalence of Helicobacter pylori infection is of 61.2% (123/201). This rate, after a statistic analysis, seems to be significantly related to age. It is particularly high especially for patients belonging to age range (20-30)-(51-60) years. The gender did not affect the infection prevalence that is more frequent in the gastritis case. We noticed also that HP infection prevalence was important in SBA the hospital. The range age (20-30)-(51-60) years had the highest prevalence of H. pylori and of gastritis which might be a risky ground of gastric cancer appearance. The ulcer pathology maximal rate concerned the group of 51 to 60 years. Above this age, this rate dropped whereas the number of patients suffering from gastric cancer, which presents an important rate in our study, increase for the group of 61-70 years.

Abstract Background The current epidemiology of upper gastrointestinal bleeding (UGIB) in Thailand is poorly understood and the reported prevalence of Helicobacter pylori infection is outdated. Objectives To investigate the etiologies of UGIB and prevalence of H. pylori infection in Thailand, including its association with UGIB. Methods We retrieved information regarding patients attending the endoscopic unit of King Chulalongkorn Memorial Hospital from June 2007 to January 2013. A database search using keywords “upper gastrointestinal bleeding” and “iron deficiency” was used. From 4,454 diagnoses, after exclusion criteria, 3,488 patients (2,042 male (58.5%) and 1,446 female (41.5%); mean age 63.3 ± 15.94 years, range 13–103 years) were included. Results The three most common causes of UGIB were peptic ulcer (38.2%), nonulcer-mucosal lesions (23.4%), and esophageal-related causes (20.4%). The 5 year-incidence of H. pylori was 25%–30%. The overall prevalence was 27%. The prevalence of H. pylori infection was found to decrease with age from 43.8% at <40 years to 21.7% at >79 years old. H. pylori infection was significantly associated with duodenal and gastroduodenal ulcers. Cirrhosis and nonulcer-mucosal lesions were significantly unrelated to H. pylori infection. Patients with concurrent cirrhosis with peptic ulcer were found to be negative for H. pylori infection. Conclusion Peptic ulcer is the leading cause of UGIB in Thailand. However, its incidence is declining. Patients who presented to hospital with UGIB were older, compared with those a decade ago. H. pylori infection plays an important role in UGIB and its incidence was stable during the past 5 years.

As an update to previously published recommendations for the management of Helicobacter pylori infection, an evidence-based appraisal of 14 topics was undertaken in a consensus conference sponsored by the Canadian Helicobacter Study Group. The goal was to update guidelines based on the best available evidence using an established and uniform methodology to address and formulate recommendations for each topic. The degree of consensus for each recommendation is also presented. The clinical issues addressed and recommendations made were: population-based screening for H pylori in asymptomatic children to prevent gastric cancer is not warranted; testing for H pylori in children should be considered if there is a family history of gastric cancer; the goal of diagnostic interventions should be to determine the cause of presenting gastrointestinal symptoms and not the presence of H pylori infection; recurrent abdominal pain of childhood is not an indication to test for H pylori infection; H pylori testing is not required in patients with newly diagnosed gastroesophageal reflux disease; H pylori testing may be considered before the use of long-term proton pump inhibitor therapy; testing for H pylori infection should be considered in children with refractory iron deficiency anemia when no other cause has been found; when investigation of pediatric patients with persistent or severe upper abdominal symptoms is indicated, upper endoscopy with biopsy is the investigation of choice; the 13C-urea breath test is currently the best noninvasive diagnostic test for H pylori infection in children; there is currently insufficient evidence to recommend stool antigen tests as acceptable diagnostic tools for H pylori infection; serological antibody tests are not recommended as diagnostic tools for H pylori infection in children; first-line therapy for H pylori infection in children is a twice-daily, triple-drug regimen comprised of a proton pump inhibitor plus two antibiotics (clarithromycin plus amoxicillin or metronidazole); the optimal treatment period for H pylori infection in children is 14 days; and H pylori culture and antibiotic sensitivity testing should be made available to monitor population antibiotic resistance and manage treatment failures.
