J Gastroenterol Hepatol. 2018 Jan;33(1):37-56. Helicobacter pylori management in ASEAN: The Bangkok consensus report. Helicobacter pylori (H. pylori) infection remains to be the major cause of important upper gastrointestinal diseases such as chronic gastritis, peptic ulcer, gastric adenocarcinoma, and mucosa-associated lymphoid tissue lymphoma.

J Gastroenterol Hepatol. 2018 Jan;33(1):37-56. Helicobacter pylori management in ASEAN: The Bangkok consensus report.

H. pylori management in ASEAN: the Bangkok consensus report gathered key opinion leaders for the region to review and evaluate clinical aspects of H. pylori infection and to develop consensus statements, rationales, and grades of recommendation for the management of H. pylori infection in clinical practice in ASEAN countries. This ASEAN Consensus consisted of 34 international experts from 10 ASEAN countries, Japan, Taiwan, and the United States. The meeting mainly focused on four issues: (i) epidemiology and disease association; (ii) diagnostic tests; (iii) management; and (iv) follow-up after eradication. The final results of each workshop were presented for consensus voting by all participants. Helicobacter. 2018 Jan 25. Comparative study of Helicobacter pylori eradication rates of concomitant therapy vs modified quadruple therapy comprising proton-pump inhibitor, bismuth, amoxicillin, and metronidazole in Korea. Background The standard triple Helicobacter pylori regimen now shows unacceptably low treatment success in Korea.

Int. J. Mol. Sci. 2018, 19(2), 338; The Prevalence of Helicobacter pylori in Estonian Bariatric Surgery Patients. Helicobacter pylori (Hp) is one of the most important human pathogens that can cause duodenal and gastric ulcers, gastritis and stomach cancer.

Int. J. Mol. Sci. 2018, 19(2), 338; The Prevalence of Helicobacter pylori in Estonian Bariatric Surgery Patients

Hp infection is considered to be a cause of limiting access to bariatric surgery. The aim of this study was to determine the prevalence of Hp in patients with obesity going into bariatric surgery and to reveal the relationship between Hp and clinical data. The study group was formed of 68 preoperative bariatric surgery patients (body mass index (BMI) 44.7 ± 4.8). Gastric biopsies (antrum and corpus) were used for histological and molecular (caqA and glmM genes) examinations. The PCR method revealed Hp infection in 64.7% of obese patients that is higher in comparison with histological analysis (55.9%).

COCHRANE LIBRARY 22/07/15 Helicobacter pylori eradication for the prevention of gastric neoplasia

Background People with H. pylori infection are more likely to develop gastric cancer than people who are not infected with the bacterium. Study characteristics A literature search up to December 2013 found 6 trials (containing 6497 participants, 3 trials at low risk of bias). Key results Quality of the evidence Three trials were at low risk of bias, one trial was at unclear risk, and two trials were at high risk of bias. Résumé simplifié. Helicobacter. 2015 Sep;20 Suppl 1:1-7. Epidemiology and Diagnosis of Helicobacter pylori infection.

During the period reviewed, prevalence studies were essentially performed in less economically advanced countries and a high prevalence was found.

The traditional risk factors for Helicobacter pylori positivity were mostly found. Transmission studied by molecular typing showed a familial transmission. The eventual role of water transmission was explored in several studies with controversial results. J Infect Dev Ctries. 2015 Jul 4;9(6):674-8.

World J Gastrointest Pharmacol Ther. 2016 Feb 6;7(1):126-32. Helicobacter pylori and its reservoirs: A correlation with the gastric infection. Helicobacter pylori (H. pylori) is a gram-negative and microaerophilic bacterium that has been associated with some certain diseases, including chronic gastritis, peptic ulcers, gastric cancer, and mucosa-associated lymphoid tissue (MALT) lymphoma.

World J Gastrointest Pharmacol Ther. 2016 Feb 6;7(1):126-32. Helicobacter pylori and its reservoirs: A correlation with the gastric infection.

In 1994, the International Agency for Research on Cancer of the World Health Organization defined H. pylori as a Group 1 carcinogen[1,2]. It is estimated that the H. pylori is present in the stomachs of 50% of the world’s population, but despite this high prevalence, we do not yet clearly understand its transmission. Possible routes are oral-oral and fecal-oral, but no consensus has been reached[3]. Currently, the main area of research into natural reservoirs for H. pylori has included oral H. pylori with gastric infection and the presence of H. pylori in the stomach[1,4]. Many studies have suggested that the primary reservoir for H. pylori is the oral cavity, but overall, the results have been very inconsistent[1-7].

PLOS 10/01/18 Metallochaperone UreG serves as a new target for design of urease inhibitor: A novel strategy for development of antimicrobials (concerne Helicobacter pilory) (avertissement de PLOS : This is an uncorrected proof.) Abstract Urease as a potential target of antimicrobial drugs has received considerable attention given its versatile roles in microbial infection.

PLOS 10/01/18 Metallochaperone UreG serves as a new target for design of urease inhibitor: A novel strategy for development of antimicrobials (concerne Helicobacter pilory) (avertissement de PLOS : This is an uncorrected proof.)

Development of effective urease inhibitors, however, is a significant challenge due to the deeply buried active site and highly specific substrate of a bacterial urease. Conventionally, urease inhibitors are designed by either targeting the active site or mimicking substrate of urease, which is not efficient. Up to now, only one effective inhibitor—acetohydroxamic acid (AHA)—is clinically available, but it has adverse side effects. Herein, we demonstrate that a clinically used drug, colloid bismuth subcitrate, utilizes an unusual way to inhibit urease activity, i.e., disruption of urease maturation process via functional perturbation of a metallochaperone, UreG.

INTECH - AVRIL 2012 - Zoonosis. Au sommaire: Helicobacter - An Emerging New Zoonotic Pathogen

Many of the zoonotic diseases are a public health concern but also affect the production of food of animal origin thus they could cause problems in international trade of animal-origin goods. A major factor contributing to the emergence of new zoonotic pathogens in human populations is increased contact between humans and animals. This book provides an insight on zoonosis and both authors and the editor hope that the work compiled in it would help to raise awareness and interest in this field. It should also help researchers, clinicians and other readers in their research and clinical usage. THE LANCET 04/02/12 Treatment of Helicobacter pylori in Latin America. In their multisite study, Robert Greenberg and colleagues1 attempted to identify a reliably effective treatment for Helicobacter pylori for use in Latin America.

THE LANCET 04/02/12 Treatment of Helicobacter pylori in Latin America

Each study site used locally available drugs and the regimens all contained clarithromycin or clarithromycin—metronidazole, despite the unacceptably low success of triple therapies elsewhere and a high expected prevalence of metronidazole resistance.2 The success of treatments for infectious diseases is mainly related to the absence of antimicrobial resistance and is predictable if one knows the pattern of resistance and the effect of resistance on the regimens tested.3, 4 Results of seven pilot studies done in six different countries with triple therapy Treatment result grade also shown. Grade A/B=good, C=acceptable, F=unacceptable. Overall, the study was well done but poorly conceived, confirming the old adage: “there is no right way to do the wrong thing”.
