Abstract
OBJECTIVE The prevalence of Helicobacter pylori resistance to amoxicillin was less than 5% in most countries. Proton pump inhibitor (PPI)-amoxicillin dual therapy dosing four times daily (q.i.d.) for 14 days could achieve an eradication rate of more than 85%. It is unclear whether dual therapy with shorter treatment duration or lower dosing frequency could also attain a satisfactory cure rate. We conducted a randomized controlled trial to assess the efficacy and safety of two modified esomeprazole-amoxicillin dual therapies, 10-day q.i.d. and 14-day three times daily (t.i.d.) dual therapy, and investigate the factors that might affect the eradication rates. PARTICIPANTS AND METHODS A total of 253 patients were screened for eligibility and 208 patients were randomly assigned to 10-day dual therapy (esomeprazole 20 mg and amoxicillin 750 mg, all given four times daily) or 14-day dual therapy (esomeprazole 20 mg and amoxicillin 1000 mg, all given three times daily). RESULTS In the intention-to-treat analysis, the eradication rates for 10-day and 14-day groups were 79.8% [95% confidence interval (CI): 70.2-87.4%] and 83.5% (95% CI: 74.3-90.5%) as first-line therapies; and 80% (95% CI: 44.4-97.5%) and 76.9% (95% CI: 46.2-95.0%) as rescue therapies. The adverse event rates were 5.9% and 5.0% for 10-day and 14-day groups, respectively. Smoking and compliance significantly affected the efficacy of PPI-amoxicillin dual therapies. CONCLUSION The eradication rate of 10-day q.i.d. dual therapy was unacceptable, while that of the 14-day t.i.d. dual therapy was borderline acceptable for first-line therapy. The two dual therapies were well tolerated with few adverse effects.

Abstract
Third generation of quinolones, such as levofloxacin and moxifloxacin, -containing regimens are often used in second-line or rescue treatment of Helicobacter pylori infection. However, the increasing antibiotic resistance to quinolones affects the efficacies of quinolones-containing therapies in recent years. Therefore, there is a need to enhance the effectiveness of quinolones-containing therapies. Sitafloxacin, a fourth-generation quinolone, and vonoprazan, a novel potassium-competitive acid blocker, are now available as more effective treatment options. The aim of this paper is to summarize the current evidence of quinolone-containing therapies in rescue treatments, and to discuss the importance of drug sensitivity tests or analysis of gyrA mutation before treatments.

Proton-pump inhibitor and amoxicillin-based triple therapy containing clarithromycin versus metronidazole for Helicobacter pylori: A meta-analysis. Microb Pathog 2020; 142:104075. [PMID: 32074497 DOI: 10.1016/j.micpath.2020.104075] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2019] [Revised: 02/14/2020] [Accepted: 02/14/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is one of the important risk factors of gastric related diseases and antibiotic therapy has become an effective treatment. At present, proton-pump inhibitor and amoxicillin-based triple therapy, including clarithromycin (PAC) and metronidazole (PAM), are two commonly used first-line therapies for H. pylori infection, which has a high incidence and possibly poor prognosis worldwide. METHODS A systematic literature review was performed using the databases PubMed, the Cochrane Library, Ovid Medline, Science Direct, Embase, Scopus and Web of Science. Only randomized clinical trials with full texts published were included. RESULTS Eighteen studies involving 3264 patients were included. The pooled risk ratios (RR) between the PAC and PAM groups were comparable in the intention-to-treat (ITT) eradication rates (71.0% versus 75.2%, RR = 0.96, p = 0.38) and per-protocol (PP) eradication rates (79.6% versus 80.1%, RR = 1.02, p = 0.65). PAM is highly effective in clarithromycin-resistant cases (70.4% versus 48.2%, RR = 0.65, p = 0.002) and that PAC showed significant efficacy in metronidazole-resistant cases (87.3% versus 58.6%, RR = 1.43, p = 0.0006). In subgroup analysis, when using low-dose PPI, the PAM group showed greater efficacy than the PAC group. Furthermore, we found that PAM showed higher effectiveness in the studies published in recent years, especially for people over 60 years old (RR = 0.80, 95% CI: 0.71-0.89, p < 0.001). CONCLUSION In general, both PAC and PAM regimens were effective and comparable in eradicating H. pylori. However, the PAM regimen showed greater efficacy than the PAC regimen in recent years, especially for people over 60 years old.

Abstract
Objective: The aim of this study was to compare the effectiveness of 10-day course of triple therapy versus a 14-day course in the treatment of H.pylori infection in an Indonesian population. Methods: A double-blinded randomized clinical trial was included patients, Indonesian population, with H.pylori infection conducted in Cipto Mangunkusumo Hospital, Jakarta; Cilincing District General Hospital, Jakarta; and West Nusa Tenggara General Hospital, Mataram, during October 2016 - April 2017. Patients were randomized to be given triple therapy as Rabeprazole 20 mg, Amoxicillin 1,000 mg, and Clarithromycin 500 mg twice daily, for 14 days or 10 days plus 4 days placebo. Eradication was evaluated with UBT at least 4 weeks after completion the therapy. Results: A total of 75 patients (38 in the 14-day group and 37 in the 10-day group) were included to the study. In the intention-to-threat analysis, eradication rate was 67.6% (95% CI. 52.5%-82.6%) for the 10-day group versus 86.8% (95% CI. 76.0%-97.5%) for the 14-day group (p = 0.046), whereas per protocol analysis obtained 73.5% (95% CI. 58.6%-88.3%) for the 10-day versus 91.9% (95% CI. 84.1%-99.6%) in the 14-day group (p = 0.039). Adverse events were not significantly different between the two groups. Conclusion: A 14-day course was more effective than 10-day course of triple therapy as first-line for eradication of H.pylori infection in an Indonesian population.

Abstract
BACKGROUND AND AIM Both clarithromycin-resistant Helicobacter pylori and CYP2C19 polymorphisms may be passed down for generations and are known risk factors for the failure of H. pylori eradication therapy. However, no study has evaluated the risk of clarithromycin triple therapy failure in patients with a parental history of such failure. This study investigated the association between a history of clarithromycin triple therapy failure in parents and clarithromycin triple therapy failure in the offspring. METHODS This cross-sectional study was conducted using a large administrative claims database of 3 100 000 insured individuals. We identified 404 patients who had both personal and parental records of prescriptions for first-line clarithromycin triple therapy between January 2005 and February 2018. Failure of clarithromycin triple therapy was defined as treatment with second-line therapy after having received first-line clarithromycin triple therapy. A parental history of clarithromycin triple therapy failure was defined as failure of clarithromycin triple therapy by either the father or the mother. Odds ratios were estimated using logistic regression models adjusted for age, sex, diabetes mellitus, and peptic ulcer. RESULTS The incidence of clarithromycin triple therapy failure was 22.5% (91/404). Based on univariate analysis (odds ratio [95% confidence interval], 1.90 [1.10-3.29]) and multivariable analysis (odds ratio [95% confidence interval], 1.93 [1.10-3.39]), parental history of clarithromycin triple therapy failure was associated with failure of clarithromycin triple therapy in the offspring. CONCLUSION A parental history of clarithromycin triple therapy failure is a risk factor for failure of clarithromycin triple therapy in the offspring.

Abstract
INTRODUCTION Helicobacter pylori selectively infects the human stomach, being the most prevalent chronic infection in the world. H pylori presence causes chronic gastritis in 100% of infected patients and is the major cause of relevant diseases such as atrophic gastritis, peptic ulcer disease, and gastric cancer; it is for this reason that from a public health standpoint, it is considered a high-impact pathogen, responsible of a significant morbidity and mortality. Nowadays, there are consensus and clinical guidelines regarding the infection management at a European level and in most of European countries, but no data have shown the level of implementation of these recommendations. The high costs that this infection carries both socially and to the health system require the continuous and systematic assessment of the diagnostic and treatment strategies, as well as the accessibility to diagnostic methods and most efficient drugs. AIM To register the diagnosis, management strategies, and treatment of H pylori-infected adult patients in the Digestive Services outpatient clinics throughout Europe. METHODS Noninterventionist prospective multicentre international Registry promoted by the European Helicobacter and Microbiota Study Group. National Coordinators will select recruiting gastroenterologists in their country that will register the H pylori-related routine clinical practice consultations they receive in an electronic case report form (e-CRF) provided by AEG-REDCap. Variables retrieved will include clinical, diagnostic, treatment, eradication confirmation, and outcome data. The database will allow researchers to perform specific subanalyses after approval by the Scientific Committee of the study.

Abstract
BACKGROUND To investigate the effects of twice daily short-message-based re-education (SMRE) before taking medicine for Helicobacter pylori (H pylori) eradication. MATERIALS AND METHODS Treatment-naive patients with H pylori infection were prescribed 14-day quadruple regimen consisting of lansoprazole 30 mg, colloidal bismuth pectin 200 mg, amoxicillin 1000 mg, and clarithromycin 500 mg twice daily. Patients were randomly allocated to SMRE group or control group. Patients in control group received oral and written instructions at outpatient clinic. In contrast, patients in the SMRE group received extra short messages including dosage and time of administration twice daily. Successful H pylori eradication was assessed using the 13 C-urea breath test 6 weeks after treatment. The compliance, adverse events, and patient satisfaction were also analyzed. RESULTS A total of 310 patients were enrolled in the intention-to-treat (ITT) and 283 in the per-protocol (PP) analysis. For young patients, the eradication rates were significantly higher in SMRE group than those in control group in PP analysis (88.6% vs 71.2%, P = 0.036), while for patients of all age groups, the eradication rate improvements were not statistically significant. The eradication rates in SMRE group and control group were 74.2% and 67.7% (P = 0.211) in ITT analysis and 82.1% and 73.4% (P = 0.078) in PP analysis, respectively. The compliance in SMRE group was significantly better than that in control group (84.8% vs 72.8%, P = 0.011). CONCLUSIONS Twice daily SMRE could improve the eradication rate in young population, as well as the compliance with treatment during H pylori eradication.

Abstract
BACKGROUND Triple therapy efficacy against Helicobacter pylori is low worldwide, and thus, alternatives must be sought to improve eradication. The aim of the present study was to determine CYP2C19 genetic polymorphism effect on H pylori eradication. METHODS A randomized, single-blinded clinical trial including 133 participants was carried out. H pylori infection was confirmed by histologic and microbiologic test. Antibiotic susceptibility to amoxicillin and clarithromycin was performed. CYP2C19 polymorphisms *1, *2, and *3 were analyzed by real-time PCR (Roche ®), and nested PCR for CYP2C19*17 polymorphisms. Participants were randomized into two groups for different H pylori therapies, one with standard omeprazole doses and another with omeprazole doses depending on CYP2C19 polymorphism. H pylori eradication was verified by stool antigen tests (Meridian ®). RESULTS The most common CYP2C19 polymorphism was *1/*1 in 54.9% of the participants followed by *17/*17 in 21.1%. Triple therapy efficacy with standard omeprazole doses versus personalized therapy based on CYP2C19 polymorphism by ITT analysis was 84% (95% CI: 0.73-0.91) vs 92.2% (95% CI: 0.82-0.97) (P = 0. 14), respectively. The efficacy by PP analysis was 92.1% (95% CI: 0.82-0.97) vs 100% (95% CI: 0.92-0.01) (P = 0.027), respectively. CONCLUSIONS The most frequent polymorphism was extensive PPI metabolizers (62.4%). Effectiveness of guided therapies by susceptibility test was good, yet they can be further improved by customized therapy based on CYP genotype. Therefore, high PPI (80 mg/d) doses are recommended for H pylori eradication therapies in Colombia. ClinicalTrials.gov ID: NCT03650543.

Abstract
BACKGROUND Bismuth-containing quadruple therapy has been suggested as first-line and rescue alternative for Helicobacter pylori eradication. Our objective was to perform a meta-analysis evaluating the efficacy and safety of single capsule Pylera® (bismuth, metronidazole, and tetracycline) plus a proton-pump inhibitor (PPI) in any line of treatment. METHODS Studies were selected up to October 2018. Outcomes were eradication and adverse events (AEs) rates pooled using the generic inverse variance method. RESULTS In total, 30 studies (6482 patients) were included in the systematic review. The intention-to-treat (ITT) efficacy was 90% (95% CI: 87%-92%, 21 studies, I2 = 88%) in first-line therapy, 89% (95% CI: 86%-93%, 12 studies, I2 = 78%) in second-line and 82% (95% CI: 78%-87%, nine studies, I2 = 60%) in third-line; with no differences by the type or dosage of PPI used. For metronidazole-resistant infection, the ITT efficacy as first-line therapy was 93% (95% CI: 90%-96%, six studies, I2 = 0%). In second-line therapies where patients had been previously treated with clarithromycin, the ITT efficacy was 90% (95% CI: 87%-93%, 11 studies, I2 = 78%). The overall incidence of AEs was 43% (95% CI: 35%-50%, 24 studies, I2 = 92%) and they were mostly mild. In nearly 3% of the cases, treatment was interrupted due to AEs. CONCLUSIONS A 10-day treatment with Pylera® achieved an effective eradication rate of approximately 90% both in first- and second-line therapy. This applies regardless of the type and dose of the PPI, in patients with clarithromycin- or metronidazole-resistant strains, and in those previously treated with clarithromycin.

Abstract
BACKGROUND AND AIM Failure of bismuth quadruple therapy for Helicobacter pylori eradication is frequently observed. To increase the eradication rate, comprehensive analyses need to be performed regarding risk factors of bismuth quadruple therapy failure based on complete standard culture and antimicrobial susceptibility testing results. METHODS Patients with history of failed first therapy who had H. pylori colonies isolated from culture and successful minimum inhibitory concentration (MIC) test were enrolled. Esomeprazole, bismuth, metronidazole, and tetracycline (quadruple) therapies for 7 or 14 days were given. Eradication rate, treatment compliance, adverse events, and risk factors for the failure of bismuth quadruple therapy were analyzed. RESULTS A total 54 patients were enrolled. Overall eradication rate in the present study was 88.8%. The eradication rate for cases with metronidazole resistance such as MIC 8-16 μg/mL or 16-32 μg/mL was 92.8% (13/14). For cases with high level metronidazole resistance (MIC > 32 μg/mL), the eradication rate was only 60% (6/10). Multivariate analysis regarding compliance, treatment duration, age > 60, three kinds of metronidazole MICs, tetracycline MIC > 4 μg/mL, adverse events and any other parameters, "metronidazole resistance, high level (MIC > 32 μg/mL)" was the only independent risk factor for eradication failure (P = 0.007). CONCLUSION For cases with metronidazole resistance at MIC > 32 μg/mL, rescue therapy other than bismuth-containing quadruple therapy is needed.

Blum FC, Singh J, Merrell DS. In vitro activity of neem (Azadirachta indica) oil extract against Helicobacter pylori. JOURNAL OF ETHNOPHARMACOLOGY 2019; 232:236-243. [PMID: 30578933 DOI: 10.1016/j.jep.2018.12.025] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2018] [Revised: 12/12/2018] [Accepted: 12/16/2018] [Indexed: 06/09/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The neem tree (Azadirachta indica A.Juss), of the Meliaceae family, has been used in India for millennia in traditional medicine. Parts of the tree are used to treat problems with the gastrointestinal tract, urinary tract, and hair; to combat infections of smallpox and plasmodium; and to treat ulcers, diabetes, blood pressure, headache, and heartburn. Natural products and extracts from the tree have been reported to have antimicrobial, antifungal, and antiparasitic activities. AIM OF THE STUDY Antibiotic resistance in the gastric pathogen Helicobacter pylori is increasing, and novel therapeutics to eradicate this bacterium are needed. Given the growing interest in the use of natural products as antimicrobials, this study was designed to examine the bactericidal effects of an extract of neem oil against H. pylori. MATERIALS AND METHODS Neem oil was obtained from a commercial source and subjected to liquid-liquid extraction with diethyl ether and aqueous methanol; the methanol-soluble fraction was retained. The minimum inhibitory (MIC) and bactericidal (MBC) concentrations were determined against nine strains of H. pylori. Additionally, specific properties of the extract were characterized using H. pylori strain G27: bactericidal kinetics, reversibility, and effectiveness under growth arrest conditions and at low pH. The hemolytic activity of the extract was measured in vitro. RESULTS The MIC and MBC of the extract against the H. pylori strains were between 25 and 51 µg/mL and 43-68 µg/mL, respectively. The bactericidal activity was time- and concentration-dependent, and at the highest concentrations (75-105 µg/mL), no detectable bacteria were present by 6 h. The activity of the extract was reversible, independent of H. pylori growth, and increased at low pH. The extract exhibited no appreciable hemolytic activity. CONCLUSIONS Neem oil extract has significant bactericidal activity against H. pylori. The extract has several favorable pharmacological properties, including ability to kill non-growing bacteria, increased activity at low pH, and no hemolytic activity. The compound(s) present in the extract could potentially be used as a future treatment for H. pylori infection.

Abstract
Primary gastric lymphoma (PGL) represents a rare pathology, which can be easily misdiagnosed because of unspecific symptoms of the digestive tract. Histologically, PGL can vary from indolent marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT) to aggressive diffuse large B-cell lymphoma (DLBCL). During the years, clinical trials revealed the important role of Helicobacter pylori (H. pylori) in the pathogenesis of gastric MALT lymphoma. Infection with Helicobacter pylori is an influential promoter of gastric lymphomagenesis initiation. Long-term studies revealed that eradication therapy could regress gastric lymphomas.

Abstract
BACKGROUND Striking prevalence of Helicobacter pylori infection has been convoluted with considerable resistance to various antibiotics worldwide. Although many eradication regimens have been introduced as the first-line therapies against H pylori, lack of appropriate multiple comparison studies makes hard to implement such results to the clinical practice. This project attempts to utilize a comprehensive network meta-analysis to pool the results of clinical trial comparing various first-line eradication therapies simultaneously in different continents. METHODS We will include all randomized controlled trials assessing the first-line regimens for treatment of H pylori published in last 10 years. We will search the databases of PubMed, EMBASE, Scopus, Web of Science and Cochrane Central Register of Controlled Trials, International Standard Randomised Controlled Trial Number registry, World Health Organisation International Clinical Trials Registry Platform, and ClinicalTrials.gov for randomized controlled trials published since January 2009 without language limitation. The primary and secondary outcomes will be H pylori eradication rate and adverse events, respectively. Subgroup analyses will be conducted for different continents. Two reviewers will independently contribute in study selection and data extraction. For evaluating quality of studies, Cochrane Collaboration tool score will be used. We will conduct network meta-analysis for treatment comparisons using STATA software version 13. RESULTS These findings will be submitted to a peer-reviewed journal for publication. CONCLUSION Our results will provide the guidance for clinicians in deferent regions to select the best possible therapeutic regimen for treatment of H pylori infected patients. REGISTRATION NUMBER This systematic review and network meta-analysis has been registered in the PROSPERO International Prospective Register of Systematic Reviews, with registration number CRD42017077061.

Abstract
AIM To evaluate the efficiency and safety of two eradication therapy (ET) regimens for Helicobacter pylori infection in patients with concomitant chronic hepatitis C (CHC) in relation to the stage of liver fibrosis (LF). MATERIALS AND METHODS A prospective clinical trial was conducted in parallel groups. Group 1 included 50 HCV-negative patients with H. pylori-associated peptic ulcer of the stomach or duodenum; Group 2 consisted of 50 HCV-positive patients with H. pylori-associated peptic ulcer of the stomach or duodenum concurrent with CHC. Each group was divided in 2 subgroups according to the used triple ET (a proton pump inhibitor (PPI) in a standard dose + amoxicillin 1000 mg twice daily + clarithromycin 500 mg twice daily for 10 days) or sequential therapy (PPI in a standard dose + amoxicillin 1000 mg twice daily within the first 5 days and then PPI in a standard dose + clarithromycin 500 mg twice daily + metronidazole 500 mg twice daily for the next 5 days). LF was assessed using indirect elastometry. The efficiency of ET was evaluated by a breath test (after 4 weeks) and an analysis depending on intention-to-treat (ITT) and per-protocol (PP) treatments. A patients recorded adverse events in specially developed diaries. RESULTS The efficiency of ET was 74% (ITT) and 80.4% (PP) in Group 1 and 76 (ITT) and 79.1% (PP) in Group 2. Both groups displayed a tendency towards an 11.9-12.4% increase in the efficiency of the sequential therapy versus the classical triple (PP) one. The rate of totally found side effects was 20% in Group 1 and 28% in Group 2. During sequential therapy, the rate of side effects was lower than that during the classical one. The efficiency of ET did not significantly depend on the stage of LF. Only the presence of concomitant type 2 diabetes mellitus and the use of macrolides (12 months before treatment) significantly lowered the efficiency of ET (OR 0,21; 95% CI 0,06-0,69, p=0,0102 and OR 0,27 95% CI 0,08-0,9, p=0,0342). LF regardless of its magnitude significantly determined the risk of adverse events during ET (OR 3,33 95% CI 1,19-9,31, p=0,0217). A group at the highest risk of adverse events included patients with liver cirrhosis (OR 4,87; 95% CI 1,01-23,5, p=0,0492). CONCLUSION It is appropriate to prescribe a sequential ET regimen as more effective and safe for patients with concomitant CHC during therapy for H. pylori infection-associated diseases. LF increases the risk of adverse events during ET.

Abstract
The aim is to conduct a comprehensive comparative study of the efficacy and safety of the hybrid scheme of eradication therapy (ET) in patients with peptic ulcer of the stomach or duodenum associated with Helicobacter pylori. Materials and methods. In a prospective, randomized comparative study, 180 patients were divided into three equal groups of 60 people, depending on the prescribed 10-day ET regimen. Group 1 - the standard triple scheme (omeprazole, amoxicillin and clarithromycin); group 2 - four-component therapy with preparations of bismuth (omeprazole, tetracycline, metronidazole, bismuth tricalium dicitrate); group 3 - hybrid scheme (first 5 days: omeprazole and amoxicillin, the next 5 days: omeprazole, amoxicillin, clarithromycin, metronidazole). The effectiveness of ET was determined with the help of a breath test a month after the end of therapy. Adverse events were recorded by patients in specially developed diaries. Pharmacoeconomic analysis was carried out using the "cost-effectiveness" method with calculation of the CER coefficient. Results and discussion. The effectiveness of standard triple therapy was 73.3% (ITT), 75.9% (PP); four-component therapy with bismuth preparations - 78.3% (ITT), 82.4% (PP); hybrid scheme - 85% (ITT), 91% (PP). Hybrid therapy proved to be significantly more effective than standard triple therapy with a odds ratio (OR) of 3.25; 95% confidence interval (CI) 1.08-9.73 (p=0.043, χ2=4.75, p-level=0.029298). The incidence of adverse events with the use of triple, four-component and hybrid ET regimens was 15; 18.3 and 28.3% respectively. The OR of at least one adverse event in patients receiving a hybrid ET regimen compared with triple therapy was 2.24 (95% CI 0.91-5.53, p=0.0823, χ2=3.14, p-level=0.076394), and compared with the four-component therapy - 1.76 (95% CI 0.74-4.17, p=0.2804, χ2=1.68, p-level=0.194924). According to the results of the pharmacoeconomic analysis, the most profitable from an economic point of view was a hybrid ET scheme with a CER of 20.1. The conclusion. Hybrid therapy showed the greatest effectiveness in comparison with the triple and four-component ET regimens, however, the incidence of side effects in patients receiving the hybrid ET scheme was higher, although it remained within the acceptable level for use in clinical practice. Pharmacoeconomic analysis also showed the advisability of designating a hybrid ET scheme. The obtained data allow to draw a conclusion about the necessity of further study of the efficiency and safety of the hybrid ET scheme.

Abstract
Although about 35 years have elapsed since the discovery of the Helicobacter pylori, its diagnosis and the choice of optimal eradication therapy are still to be defined. Over time, there has been an increase in interest, publications, recommendations and guidelines. Moreover, management of the disease in pediatric subjects differs somewhat to that of adults and requires a more delicate approach leading to alternative strategies for both diagnosis and treatment. Which patient should be investigated for H. pylori, when to perform noninvasive or invasive tests, what are the proper therapeutic options and best antibiotics regimen to eradicate the infection are practices changing with evidences through time. Therefore, an updated guideline was published by the European Society of Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) in 2017. The aim of this review is to highlight what is new and what differs between adult and pediatric population regarding the management of H. pylori infection after the ESPGHAN/NASPGHAN guidelines, enriched with updates from literature reviews published over the last two years.

Abstract
Important advances have been made since the last Mexican consensus on the diagnosis and treatment of Helicobacter pylori (H. pylori) infection was published in 2007. Therefore, the Asociación Mexicana de Gastroenterología summoned 20 experts to produce "The Fourth Mexican Consensus on Helicobacter pylori". From February to June 2017, 4 working groups were organized, a literature review was performed, and 3 voting rounds were carried out, resulting in the formulation of 32 statements for discussion and consensus. From the ensuing recommendations, it was striking that Mexico is a country with an intermediate-to-low risk for gastric cancer, despite having a high prevalence of H. pylori infection. It was also corroborated that peptic ulcer disease, premalignant lesions, and histories of gastric cancer and mucosa-associated lymphoid tissue lymphoma should be considered clear indications for eradication. The relation of H. pylori to dyspeptic symptoms continues to be controversial. Eradication triple therapy with amoxicillin, clarithromycin, and a proton pump inhibitor should no longer be considered first-line treatment, with the following 2 options proposed to take its place: quadruple therapy with bismuth (proton pump inhibitor, bismuth subcitrate, tetracycline, and metronidazole) and quadruple therapy without bismuth (proton pump inhibitor, amoxicillin, clarithromycin, and metronidazole). The need for antimicrobial sensitivity testing when 2 eradication treatments have failed was also established. Finally, the promotion of educational campaigns on the diagnosis and treatment of H. pylori for both primary care physicians and the general population were proposed.

Abstract
BACKGROUND Infection with Helicobacter pylori (H. pylori) is a major pathogenic factor for gastroduodenal ulcer disease and gastric carcinoma, as well as for other types of gastric and extragastric disease. As a result of changing epidemiologic conditions (e.g., immigration), changing resistance patterns with therapeutic implications, and new knowledge relating to the indications for pathogen eradication, the medical management of H. pylori is a dynamic process in need of periodic reassessment. METHODS This review is based on pertinent publications retrieved by a selective search in PubMed and the Cochrane Database, with particular attention to three international consensus reports and the updated German S2k guideline. RESULTS H. pylori is now dealt with as an infection, whether or not the infected individual has symptoms or suffers from and H.-pylori-induced illness. H.-pylori-associated dyspepsia and functional dyspepsia are distinct entities that can only be diagnosed when competing elements in the differential diagnosis have been ruled out. H. pylori can be detected with noninvasive methods (13C-urea breathing test, stool antigen detection) and with invasive methods (histology, culture, rapid urease test). An important consideration for treatment is that primary clarithromycin resistance is common in many groups of patients; in Germany, its prevalence is now 10.9%. Primary treatment can be with either standard triple therapy (clarithromycin and amoxicillin or metronidazole) or bismuth-containing quadruple therapy. Treatment for 10 to 14 days is more likely to eradicate the pathogen than treatment for 7 days. When H. pylori infection is initially diagnosed in a patient over age 50, gastritis risk stratification should be performed by means of endoscopic biopsy and histologic examination. CONCLUSION The new, clinically relevant developments that are presented and commented upon in this review now enable evidence-based management of H. pylori infection.

Abstract
BACKGROUND Helicobacter pylori eradication rates with standard triple therapy in many countries are clinically unacceptable. Fluoroquinolone resistance is increasing and jeopardizing second-line regimens. There is a growing need for an effective strategy in patients who failed previous therapies. METHODS This is a single-center, non-randomized clinical study conducted in the central region of Portugal. Sixty-four patients were included with a positive 13C-urea breath test (UBT) or histology for H. pylori, and at least one failed eradication attempt. The patient cohort included 71.7% of females with a median of age of 52 (range 23-87). They were treated with a twelve-day regimen consisting of a proton-pump inhibitor (PPI) bid, amoxicillin at 1,000 mg 12/12 h and levofloxacin at 500 mg bid during the first seven days, followed by PPI bid, clarithromycin at 500 mg 12/12h and either tinidazole or metronidazole at 500 mg bid/tid for five days. Eradication was assessed by UBT. The local Ethics Committee approved this study. RESULTS Eradication therapy was prescribed due to dyspepsia (66.7%), peptic ulcer (10%) and thrombocytopenia (8.3%). The median number of failed therapies was one (range 1-4). The eradication rate was 64.6% according to an intention-to-treat analysis (95% CI: 53-77%), and 70% by the per-protocol analysis (95% CI: 58-82%). Age, smoking, indication for eradication, previous therapies and the use of a second-generation or full-dose PPI did not affect success rates. CONCLUSIONS Even though treatment with four antibiotics was used, this "reinforced" therapy achieved suboptimal results. This fact highlights the lack of effective H. pylori antimicrobials and suggests that second-line treatment in our region should be prescribed according to susceptibility testing.

Abstract
OBJECTIVE To determine the optimal regimen of different first-line Helicobacter pylori eradication therapies according to the clarithromycin resistance rate. DESIGN Electronic search for articles published between January 2005 and April 2016. Randomised, controlled trials that reported the effectiveness of first-line eradication therapies in treatment-naïve adults were included. Two independent reviewers performed articles screening and data extraction. Network and traditional meta-analyses were conducted using the random effect model. Subgroup analyses were performed to determine the ranking of regimens in countries with high (>15%) and low (<15%) clarithromycin resistance. Data including adverse events and therapeutic cure rate were also extracted and analysed. RESULTS 117 trials (totally 32 852 patients) for 17 H. pylori eradication regimens were eligible for inclusion. Compared with 7-day clarithromycin-based triple therapy, sequential therapy (ST) for 14 days had the highest effectiveness (OR=3.74, 95% CrI 2.37 to 5.96). ST-14 (OR=6.53, 95% CrI 3.23 to 13.63) and hybrid therapy (HY) for 10 days or more (OR=2.85, 95% CrI 1.58 to 5.37) represented the most effective regimen in areas with high and low clarithromycin resistance, respectively. The effectiveness of standard triple therapy was below therapeutic eradication rate in most of the countries. Longer duration was associated with higher eradication rate, but with a higher risk of events that lead to discontinuation. CONCLUSIONS ST and HY appeared to be the most effective therapies in countries with high and low clarithromycin resistance, respectively. The clinical decision for optimal regimen can be supported by referring to the rank ordering of relative efficacies stratified by local eradication rates, antibiotic resistance and safety profile. TRIAL REGISTRATION NUMBER CRD42015025445.

Abstract
Objective.
Compare the in vitro activity of clarithromycin, erythromycin, azithromycin and josamycin against the collection of H. pylori strains isolated in 2010–2017 in Smolensk.
Materials and Methods.
H. pylori strains were collected prospectively from biopsy specimens of the gastric mucosa. Antimicrobial susceptibility testing of H. pylori was performed by the agar dilution method. Interpretation of the results of the susceptibility determination for clarithromycin was carried out in accordance with the recommendations of EUCAST (v 8.0) 2018. The resistance breakpoints for erythromycin, azithromycin, and josamycin were all set at ≥1.0 mg/L. For comparison of the results, the value of the minimal inhibitory concentrations of the tested antibiotic inhibiting the growth of 50% (MIC50) and 90% (MIC90) of H. pylori strains was used.
Results.
A total of 276 H. pylori strains were tested. 90% of the MIC values of clarithromycin were in the range from 0.015 to 0.125 mg/l. The percentages of resistance were as follows: clarithromycin 5.1%, azithromycin 7.5%, erythromycin 8%, josamycin 23.2%. Clarithromycin demonstrated significantly higher activity in suppressing the growth of H. pylori strains than azithromycin, erythromycin, and josamycin.
Conclusions.
Among the tested macrolide antibiotics maximal anti-H. pylori activity in vitro was observed in clarithromycin.

Abstract
BACKGROUND Bismuth quadruple therapy (BQT) has been proven superior to standard triple therapy for Helicobacter pylori eradication in randomized clinical trials; however, little is known about the efficacy of BQT in daily routine practice. METHODS In a single-center cohort study, we analyzed consecutive H. pylori-positive patients in whom three-in-one capsule BQT (Pylera® + omeprazole) has been prescribed. All patients were instructed in a standardized fashion, and a prospective follow-up was planned. PCR on gastric biospies for clarithromycin and levofloxacin resistance was performed before treatment in a subgroup of patients. Treatment outcome was assessed by 13C urea breath test or by histology not earlier than 4 weeks after end of treatment. RESULTS Three-in-one capsule BQT has been prescribed in 322 patients. Approximately 70.2% of patients had a migrational background. PCR results were available in 163 patients and identified resistance to clarithromycin and levofloxacin in 29 (17.8%) and 20 (12.3%) of cases, respectively. BQT was prescribed as first-line, second-line, and salvage treatments in 74%, 17%, and 9% of cases, respectively. Five patients discontinued treatment due to side effects (1.8%). By modified intention-to-treat and per-protocol analyzes, the overall H. pylori eradication rates were 95.0% (95% CI 94.92%-95.08%) and 96.7% (95% CI 94.6%-98.8%), respectively. The low number of treatment failures (n = 9) did not allow to identify risk factors for failure. CONCLUSION Three-in-one capsule bismuth quadruple therapy is effective and safe for treatment of H. pylori infection in routine practice, irrespective of the patient's migrational background or the number of previous treatment failures.

Abstract
Background Probiotics are commonly used for the prevention of antibiotic-associated diarrhea (AAD). However, the optimum regimen remains controversial. Objective The objective of this article is to compare and rank the relative efficacy and tolerability among all available probiotic agents for AAD through a network meta-analysis. Methods Eligible studies were identified by searching PubMed, Embase, Medline, Cochrane library and Web of Science for randomized controlled trials (RCTs) that examined the efficacy of probiotic therapy for AAD. A random-effects model was applied within a frequentist framework. Quality of evidence was performed by the GRADE approach. The project was prospectively registered with PROSPERO (CRD 42016050776). Results Fifty-one articles (60 comparisons, 9569 participants), including 10 probiotic interventions, were identified. Lactobacillus rhamnosus GG (LGG) had the highest probability of being ranked best both in effectiveness (odds ratio (OR), 95% confidence interval (CI) = 0.28 (0.17, 0.47)) and tolerance (0.44 (0.23, 0.84)) on prevention of AAD. With regard to reducing Clostridium difficile infection rate, Lactobacillus casei (L. casei) was considered better efficacy (0.04 (0.00, 0.77)) and medium tolerance (0.56 (0.19, 1.66)). Strain combination reported no superiority over single strain in either efficacy or tolerability. Conclusions LGG is probably the best option to consider when AAD is indicated. L. casei appears to be the most efficacious choice when associated with severe C. difficile-related cases.

Abstract
IMPORTANCE Non-vitamin K oral anticoagulants (NOACs) are commonly prescribed with other medications that share metabolic pathways that may increase major bleeding risk. OBJECTIVE To assess the association between use of NOACs with and without concurrent medications and risk of major bleeding in patients with nonvalvular atrial fibrillation. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study using data from the Taiwan National Health Insurance database and including 91 330 patients with nonvalvular atrial fibrillation who received at least 1 NOAC prescription of dabigatran, rivaroxaban, or apixaban from January 1, 2012, through December 31, 2016, with final follow-up on December 31, 2016. EXPOSURES NOAC with or without concurrent use of atorvastatin; digoxin; verapamil; diltiazem; amiodarone; fluconazole; ketoconazole, itraconazole, voriconazole, or posaconazole; cyclosporine; erythromycin or clarithromycin; dronedarone; rifampin; or phenytoin. MAIN OUTCOMES AND MEASURES Major bleeding, defined as hospitalization or emergency department visit with a primary diagnosis of intracranial hemorrhage or gastrointestinal, urogenital, or other bleeding. Adjusted incidence rate differences between person-quarters (exposure time for each person during each quarter of the calendar year) of NOAC with or without concurrent medications were estimated using Poisson regression and inverse probability of treatment weighting using the propensity score. RESULTS Among 91 330 patients with nonvalvular atrial fibrillation (mean age, 74.7 years [SD, 10.8]; men, 55.8%; NOAC exposure: dabigatran, 45 347 patients; rivaroxaban, 54 006 patients; and apixaban, 12 886 patients), 4770 major bleeding events occurred during 447 037 person-quarters with NOAC prescriptions. The most common medications co-prescribed with NOACs over all person-quarters were atorvastatin (27.6%), diltiazem (22.7%), digoxin (22.5%), and amiodarone (21.1%). Concurrent use of amiodarone, fluconazole, rifampin, and phenytoin with NOACs had a significant increase in adjusted incidence rates per 1000 person-years of major bleeding than NOACs alone: 38.09 for NOAC use alone vs 52.04 for amiodarone (difference, 13.94 [99% CI, 9.76-18.13]); 102.77 for NOAC use alone vs 241.92 for fluconazole (difference, 138.46 [99% CI, 80.96-195.97]); 65.66 for NOAC use alone vs 103.14 for rifampin (difference, 36.90 [99% CI, 1.59-72.22); and 56.07 for NOAC use alone vs 108.52 for phenytoin (difference, 52.31 [99% CI, 32.18-72.44]; P < .01 for all comparisons). Compared with NOAC use alone, the adjusted incidence rate for major bleeding was significantly lower for concurrent use of atorvastatin, digoxin, and erythromycin or clarithromycin and was not significantly different for concurrent use of verapamil; diltiazem; cyclosporine; ketoconazole, itraconazole, voriconazole, or posaconazole; and dronedarone. CONCLUSIONS AND RELEVANCE Among patients taking NOACs for nonvalvular atrial fibrillation, concurrent use of amiodarone, fluconazole, rifampin, and phenytoin compared with the use of NOACs alone, was associated with increased risk of major bleeding. Physicians prescribing NOAC medications should consider the potential risks associated with concomitant use of other drugs.

Abstract
Bifidobacteria are members of the intestinal microbiota of mammals and other animals, and some strains are able to exert health-promoting effects. The genus Bifidobacterium belongs to the Actinobacteria phylum. Firmicutes, Bacteroidetes, and Actinobacteria constitute the most abundant phyla in the human intestinal microbiota, Firmicutes and Bacteroidetes being predominant in adults, and Actinobacteria in breast-fed infants, where bifidobacteria can reach levels higher than 90% of the total bacterial population. They are among the first microbial colonizers of the intestines of newborns, and play key roles in the development of their physiology, including maturation of the immune system and use of dietary components. Indeed, some nutrients, such as human milk oligosaccharides, are important drivers of bifidobacterial development. Some Bifidobacterium strains are considered probiotic microorganisms because of their beneficial effects, and they have been included as bioactive ingredients in functional foods, mainly dairy products, as well as in food supplements and pharma products, alone, or together with, other microbes or microbial substrates. Well-documented scientific evidence of their activities is currently available for bifidobacteria-containing preparations in some intestinal and extraintestinal pathologies. In this review, we focus on the role of bifidobacteria as members of the human intestinal microbiota and their use as probiotics in the prevention and treatment of disease.

Abstract
BACKGROUND Several probiotics were effective in the eradication treatment for Helicobacter pylori (Hp), but their comparative efficacy was unknown. AIM To compare the efficacy of different probiotics when supplemented in Hp eradication therapy. METHODS A comprehensive search was conducted to identify all relevant studies in multiple databases and previous meta-analyses. Bayesian network meta-analysis was performed to combine direct and indirect evidence and estimate the relative effects. RESULTS One hundred and forty studies (44 English and 96 Chinese) were identified with a total of 20,215 patients, and more than 10 probiotic strategies were supplemented in Hp eradication therapy. The rates of eradication and adverse events were 84.1 and 14.4% in probiotic group, while 70.5 and 30.1% in the control group. In general, supplementary probiotics were effective in improving the efficacy of Hp eradication and decreasing the incidence of adverse events, despite of few ineffective subtypes. In triple eradication therapy, there was no significant difference among the effective probiotics, and combined probiotics did not show a better efficacy and tolerance than single use. In triple therapy of 7 days and 14 days, Lactobacillus acidopilus was a slightly better choice, while Saccharomyces boulardii was more applicable for 10-day triple therapy. CONCLUSIONS Compared to placebo, most probiotic strategies were effective when supplemented in Hp eradication therapy. In triple eradication therapy, no probiotic showed a superior efficacy to the others. Compared to single use, combined probiotics could not improve the efficacy or tolerance significantly.

Abstract
BACKGROUND As with any other infectious disease, we should aim for treatments offering ≥90% Helicobacter pylori eradication rates in clinical practice. AIM To summarize optimization strategies aimed to increase the efficacy of H. pylori eradication therapies. METHODS A systematic bibliographic search (in PubMed up to August 2016) was designed to identify studies investigating optimization strategies aimed to increase the efficacy of H. pylori eradication therapies. RESULTS The most direct way to optimize a treatment is using higher doses of drugs unless it has been shown that lower doses are equally effective. Similarly, prescriptions should use 14-day duration unless a shorter scheme has been shown locally to be equally effective. Double-dose proton-pump inhibitor therapy is recommended for triple therapy and may probably increase the efficacy of nonbismuth concomitant regimen as well. The efficacy of triple therapies in the presence of resistance can be significantly improved by the addition of bismuth salts, which offer an additive effect in combination with antibiotics. Overall, probiotics seem to reduce antibiotic side effects, but the increase in eradication rates is not so evident; therefore, they cannot be generally recommended for clinical practice yet. CONCLUSIONS Using potent acid inhibition and/or higher antibiotic doses-especially by increasing the number of daily intakes-and lengthening treatments up to 14 days improves efficacy in most regimens and should be generally recommended. Triple therapies can be efficiently improved by the addition of bismuth salts, turning them into quadruple therapies. Finally, some treatments will require a combination of optimization strategies to significantly improve results.

Abstract
PURPOSE The aim of this randomized placebo-controlled clinical study was to investigate the effects of a probiotic tablet containing Lactobacillus reuteri in peri-implantitis patients. METHODS Subjects comprised 30 patients with mild to moderate peri-implantitis. A baseline clinical examination and microbiological assessment were conducted, followed by an antibiotics treatment (azithromycin, 500mg, once a day for 3 days). Subjects were divided into probiotic and placebo groups. The clinical examination and bacterial sampling were performed 0, 4, 12 and 24 weeks after the intake of probiotics. The clinical examination included probing pocket depth (PPD), bleeding on probing (BOP), the modified plaque index (mPI), and modified bleeding index (mBI). The number of bacteria was assessed using the PCR-invader method. The Wilcoxon rank-sum test and Wilcoxon signed-rank test with Bonferroni corrections were used for data analyses. RESULTS Although the number of bacteria decreased after the administration of azithromycin in both groups, they increased again thereafter. No significant difference was observed in bacterial numbers between the two groups. Although PPD in the probiotics group was significantly lower at 4 and 24 weeks than at 0 weeks (p<0.05), a significant decrease did not occur in the placebo group. The mBI score at 24 weeks was significantly lower in the probiotics group than in the placebo group (p<0.05). No significant difference was observed in BOP or mPI between the two groups. CONCLUSION These results suggested that probiotics prevent inflammation by affecting host responses rather than improving microbial flora in peri-implant sulci in peri-implantitis patients.

Abstract
Helicobacter pylori (H. pylori) treatment remains a challenge for the clinician, as no available therapy is able to cure the infection in all treated patients. In the last two decades, several antibiotic combinations have been proposed, including triple therapies, bismuth-free therapies (sequential, concomitant, hybrid regimens), and bismuth-based quadruple therapy. Some national and international guidelines on H. pylori management have recently been updated, recommending or discouraging the use of each of these therapeutic approaches, based mainly on the presumed pattern of primary antibiotic resistance in different geographic areas. We examined the recommendations on first-line therapies in the most recently updated guidelines worldwide, taking into account other data affecting the efficacy of a therapy regimen beyond the primary resistance pattern. Although several guidelines highlighted that the results achieved by an eradication therapy are population-specific and not directly transferable, it emerged that some therapy regimens are recommended or discouraged with no mention of the vital need for national data.

Abstract
BACKGROUND Because of the changing epidemiology of Helicobacter pylori infection and low efficacy of currently recommended therapies, an update of the European Society for Paediatric Gastroenterology Hepatology and Nutrition/North American Society for Pediatric Gastroenterology, Hepatology and Nutrition recommendations for the diagnosis and management of H pylori infection in children and adolescents is required. METHODS A systematic review of the literature (time period: 2009-2014) was performed. Representatives of both societies evaluated the quality of evidence using GRADE (Grading of Recommendation Assessment, Development, and Evaluation) to formulate recommendations, which were voted upon and finalized using a Delphi process and face-to-face meeting. RESULTS The consensus group recommended that invasive diagnostic testing for H pylori be performed only when treatment will be offered if tests are positive. To reach the aim of a 90% eradication rate with initial therapy, antibiotics should be tailored according to susceptibility testing. Therapy should be administered for 14 days, emphasizing strict adherence. Clarithromycin-containing regimens should be restricted to children infected with susceptible strains. When antibiotic susceptibility profiles are not known, high-dose triple therapy with proton pump inhibitor, amoxicillin, and metronidazole for 14 days or bismuth-based quadruple therapy is recommended. Success of therapy should be monitored after 4 to 8 weeks by reliable noninvasive tests. CONCLUSIONS The primary goal of clinical investigation is to identify the cause of upper gastrointestinal symptoms rather than H pylori infection. Therefore, we recommend against a test and treat strategy. Decreasing eradication rates with previously recommended treatments call for changes to first-line therapies and broader availability of culture or molecular-based testing to tailor treatment to the individual child.

Abstract
Helicobacter pylori (H. pylori) infection is a common worldwide infection that is an important cause of peptic ulcer disease and gastric cancer. H. pylori may also have a role in uninvestigated and functional dyspepsia, ulcer risk in patients taking low-dose aspirin or starting therapy with a non-steroidal anti-inflammatory medication, unexplained iron deficiency anemia, and idiopathic thrombocytopenic purpura. While choosing a treatment regimen for H. pylori, patients should be asked about previous antibiotic exposure and this information should be incorporated into the decision-making process. For first-line treatment, clarithromycin triple therapy should be confined to patients with no previous history of macrolide exposure who reside in areas where clarithromycin resistance amongst H. pylori isolates is known to be low. Most patients will be better served by first-line treatment with bismuth quadruple therapy or concomitant therapy consisting of a PPI, clarithromycin, amoxicillin, and metronidazole. When first-line therapy fails, a salvage regimen should avoid antibiotics that were previously used. If a patient received a first-line treatment containing clarithromycin, bismuth quadruple therapy or levofloxacin salvage regimens are the preferred treatment options. If a patient received first-line bismuth quadruple therapy, clarithromycin or levofloxacin-containing salvage regimens are the preferred treatment options. Details regarding the drugs, doses and durations of the recommended and suggested first-line and salvage regimens can be found in the guideline.

Abstract
BACKGROUND Epidermal growth factor receptor (EGFR) mutation testing in tumor tissue is now a common practice in selecting non-small cell lung cancer (NSCLC) patients for EGFR tyrosine kinase inhibitor (TKI) treatment. However, tumor tissues are often absent or insufficient for the testing. Blood is a potential substitute providing a noninvasive, easily accessible and repeatedly measureable source of genotypic information. However which is the best blood EGFR mutation testing method remains unclear. We undertake this study to investigate the best blood EGFR mutation testing method for selecting EGFR TKI treatment in patients with NSCLC. METHODS This study was registered in PROSPERO (CRD42017055263). PubMed, EMBASE, Cochrane library, and NIHR Health Technology Assessment program will be searched. Studies fulfill the following criteria will be eligible: (1) randomized controlled trials or cohort studies; (2) included patients with NSCLC; (3) reported response, progression-free survival, or overall survival for EGFR TKI by the EGFR mutation status in blood sample. Diagnostic accuracy of blood EGFR mutation tests for predicting response to TKI will be pooled. Tumor response, progression-free survival, and overall survival according to different blood EGFR mutation testing methods will be evaluated and compared. RESULTS Based published data and combined analysis, this study will quantitatively compare the blood EGFR mutation testing methods according to their accuracy for predicting treatment response and relationship with clinical outcome in NSCLC patients treated with EGFR TKIs. CONCLUSION This protocol will determine the best blood EGFR mutation testing method.

Abstract
Objective: Helicobacter pylori (H. pylori) eradication remains a challenge with increasing antibiotic resistance. Hybrid therapy has attracted widespread attention because of initial report with good efficacy and safety. However, many issues on hybrid therapy are still unclear such as the eradication efficacy, safety, compliance, influencing factors, correlation with antibiotic resistance, and comparison with other regimens. Therefore, a comprehensive review on the evidence of hybrid therapy for H. pylori infection was conducted. Data Sources: The data used in this review were mainly from PubMed articles published in English up to September 30, 2015, searching by the terms of “Helicobacter pylori” or “H. pylori”, and “hybrid”. Study Selection: Clinical research articles were selected mainly according to their level of relevance to this topic. Results: Totally, 1871 patients of 12 studies received hybrid therapy. The eradication rates were 77.6–97.4% in intention-to-treat and 82.6–99.1% in per-protocol analyses. Compliance was 93.3–100.0%, overall adverse effects rate was 14.5–67.5%, and discontinued medication rate due to adverse effects was 0–6.7%. H. pylori culture and sensitivity test were performed only in 13.3% patients. Pooled analysis showed that the eradication rates with dual clarithromycin and metronidazole susceptible, isolated metronidazole or clarithromycin resistance, and dual clarithromycin and metronidazole resistance were 98.5%, 97.6%, 92.9%, and 80.0%, respectively. Overall, the efficacy, compliance, and safety of hybrid therapy were similar with sequential or concomitant therapy. However, hybrid therapy might be superior to sequential therapy in Asians. Conclusions: Hybrid therapy showed wide differences in the efficacy but consistently good compliance and safety across different regions. Dual clarithromycin and metronidazole resistance were the key factor to efficacy. Hybrid therapy was similar to sequential or concomitant therapy in the efficacy, safety, and compliance.

Abstract
BACKGROUND Whether concomitant therapy is superior to bismuth quadruple therapy or 14-day triple therapy for the first-line treatment of Helicobacter pylori infection remains poorly understood. We aimed to compare the efficacy and safety of 10-day concomitant therapy, 10-day bismuth quadruple therapy, and 14-day triple therapy in the first-line treatment of H pylori. METHODS In this multicentre, open-label, randomised trial, we recruited adult patients (aged >20 years) with H pylori infection from nine medical centres in Taiwan. Patients who had at least two positive tests from the rapid urease test, histology, culture, or serology or who had a single positive 13C-urea breath test for gastric cancer screening were eligible for enrolment. Patients were randomly assigned (1:1:1) to either concomitant therapy (lansoprazole 30 mg, amoxicillin 1 g, clarithromycin 500 mg, and metronidazole 500 mg, all given twice daily) for 10 days; bismuth quadruple therapy (bismuth tripotassium dicitrate 300 mg four times a day, lansoprazole 30 mg twice daily, tetracycline 500 mg four times a day, and metronidazole 500 mg three times a day) for 10 days; or triple therapy (lansoprazole 30 mg, amoxicillin 1 g, and clarithromycin 500 mg, all given twice daily) for 14 days. A computer-generated permuted block randomisation sequence with a block size of 6 was used for randomisation, and the sequence was concealed in an opaque envelope until the intervention was assigned. Investigators were masked to treatment allocation. The primary outcome was the eradication frequency of H pylori with first-line therapy assessed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01906879. FINDINGS Between July 17, 2013, and April 20, 2016, 5454 patients were screened for eligibility. Of these, 1620 patients were randomly assigned in this study. The eradication frequencies were 90·4% (488/540 [95% CI 87·6-92·6]) for 10-day bismuth quadruple therapy, 85·9% (464/540 [82·7-88·6]) for 10-day concomitant therapy, and 83·7% (452/540 [80·4-86·6]) for 14-day triple therapy in the intention-to-treat analysis. 10-day bismuth quadruple therapy was superior to 14-day triple therapy (difference 6·7% [95% CI 2·7-10·7, p=0·001), but not 10-day concomitant therapy. 10-day concomitant therapy was not superior to 14-day triple therapy. The frequency of adverse events was 67% (358/533) in patients treated with 10-day bismuth quadruple therapy, 58% (309/535) in patients treated with 10-day concomitant therapy, and 47% (252/535) in patients treated with 14-day triple therapy. INTERPRETATION Bismuth quadruple therapy is preferable to 14-day triple therapy in the first-line treatment in the face of rising prevalence of clarithromycin resistance. Concomitant therapy given for 10 days might not be optimum and a longer treatment length should be considered.

Abstract
Helicobacter pylori infection has been implicated as trigger or disease modifier in immune thrombocytopenia (ITP). So, eradication treatment for this agent could have clinical benefits. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified four systematic reviews comprising 40 studies addressing the question of this article overall, including one randomized controlled trial. We combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded Helicobacter eradication might decrease risk of bleeding in patients with immune thrombocytopenia but the certainty of the evidence is low.

Abstract
Many interesting articles have been published from different parts of the world over the last year assessing various issues around Helicobacter pylori eradication therapy. This article will address the published literature over the last year pertaining to the topic of treatment of H. pylori infection. The main themes that emerge are assessing the efficacy of standard triple therapy, as well as exploring new first-line treatments, mainly optimized nonbismuth-containing and bismuth-containing quadruple therapies with some promising data also emerging on dual therapy. There was also considerable progress in investigating antibiotic resistance rates with much more data emerging from varied parts of the world compared to recent years. Advances in the use of adjunctive therapies, especially probiotic therapies have also been made. Undoubtedly, the eradication of H. pylori remains a worthwhile goal to alleviate the burden of diseases caused by the complications of this infection, including dyspepsia, peptic ulcer disease, and gastric cancer.

Abstract
The risk of sepsis is low. The best probiotic to optimize outcomes has not yet been identified. Potential benefit for CD4 count, recurrence or management of bacterial vaginosis and diarrhea. Uncertain effect on translocation, BV treatment. People living with human immunodeficiency virus frequently use dietary supplements, including probiotics, but concern exists about ingesting live organisms. We performed a systematic review of the benefits of probiotics and a meta-analysis of sepsis risk. We undertook a protocol-driven, comprehensive review to identify all relevant studies, assess their quality, and summarize the evidence. Of 2068 references, 27 were analyzed. The data suggest possible benefits for CD4 count, recurrence or management of bacterial vaginosis, and diarrhea management. We examined randomized, controlled studies explicitly assessing sepsis in any patient population, and we found zero cases of supplement-associated bacteremia or fungemia in 39 randomized controlled trials comprising 9402 subjects. The estimated number needed to harm is 7369 in Bayesian approach (95% credible interval: 1689, ∞), which should reassure clinicians. No or mild adverse effects were reported. Longer duration studies investigating different individual and mixed strains for plausible indications are needed to establish best practices.

Abstract
Helicobacter pylori infection has accompanied man for thousands of years. In some infected patients, a complex and dynamic pathogen-host reaction triggers pathogenic pathways resulting in development, inter alia, of atrophic gastritis, peptic ulcer disease (both gastric and duodenal), gastric adenocarcinoma, and MALT lymphoma. Large-scale eradication therapy is associated with a rapid increase in antibiotic resistance, gut flora composition disturbances, and increased risk of development, inter alia, of paediatric infectious diarrhoeas, atopic diseases, and oesophageal adenocarcinoma. Our diet contains many substances with potent antibacterial activity against H. pylori. Dietary interventions enable a decrease in H. pylori colonisation and result in a decrease in gastritis prevalence, thus potentially lowering the risk of gastric adenocarcinoma development.

Abstract
BACKGROUND Currently only a few studies compare sequential and concomitant non-bismuth Helicobacter pylori therapies referring to high antibiotic resistance populations. MATERIALS AND METHODS This multicenter prospective randomized clinical trial included 353 H. pylori positive, treatment naïve, patients. All patients had positive CLO-test and/or histology and culture. They received sequential (esomeprazole 40mg, amoxicillin 1g/bid for 5days, followed by 5days of esomeprazole 40mg, clarithromycin 500mg and metronidazole 500mg bid), or concomitant treatment (all drugs taken concomitantly bid for 10days). Eradication was confirmed by (13)C-urea breath test or histology 4-6weeks after treatment. Adverse events and adherence were evaluated. RESULTS Allocated to concomitant were 175 (72F/103M, mean 52.3years, 38.3% smokers, 25.7% ulcer disease) and 178 (87F/91M, mean 52years, 31% smokers, 19.1% ulcer disease) patients to sequential treatment. There were 303/353 (85.8%) positive cultures, with the following resistances: 34% metronidazole, 27.7% clarithromycin, and 7.9% dual. Eradication rates were, respectively, 89.1% (156/175) vs. 78.7% (140/178) by intention to treat (p=0.01, 95% CI=2.7-18) and 93.4%(156/167) vs. 82.8% (140/169) per protocol (p=0.004, 95% CI=3.6-17.6). Overall, adherence was (98.9%, 95% CI=97-100). Eradication rates according to resistance were the following: dual susceptible strains 67/69 (97.1%), 62/67 (92%) (p=0.4), metronidazole single resistant 38/39 (97.4%), 31/39 (79.5%) (p=0.03, 95% CI=3.5-33), clarithromycin single resistant 25/28 (89.3%), 26/31 (83.9%) (p=0.8), and dual resistant 9/12 (75%), 4/11 (36.4%) (p=0.1) for concomitant and sequential regimens, respectively. Side effects were comparable among regimens, except from diarrhea being more frequent among patients treated with concomitant treatment. CONCLUSIONS Concomitant treatment eradication rate overcomes 90% per protocol and has a significant advantage over sequential therapy. This is probably due to its better efficacy on metronidazole resistant strains. Both regimens were well tolerated and safe.

World J Gastroenterol 2016; 22:5445-5453. [PMID: 27340362 PMCID: PMC4910666 DOI: 10.3748/wjg.v22.i23.5445] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2016] [Revised: 04/08/2016] [Accepted: 05/04/2016] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the applicability of nonbismuth concomitant quadruple therapy for Helicobacter pylori (H. pylori) eradication in Chinese regions.
METHODS: A systematic review and meta-analysis of randomized controlled trials was performed to evaluate the efficacy of nonbismuth concomitant quadruple therapy between sequential therapy or triple therapy for H. pylori eradication in Chinese regions. The defined Chinese regions include China, Hong Kong, Taiwan, and Singapore. The primary outcome was the H. pylori eradication rate; the secondary outcome was the compliance with therapy. The PubMed, Embase, Scopus, and Cochrane databases were searched for studies published in the period up to March 2016 with no language restriction.
RESULTS: We reviewed six randomized controlled trials and 1616 patients. In 3 trials comparing concomitant quadruple therapy with triple therapy, the H. pylori eradication rate was significantly higher for 7-d nonbismuth concomitant quadruple therapy than for 7-d triple therapy (91.2% vs 77.9%, risk ratio = 1.17, 95%CI: 1.09-1.25). In 3 trials comparing quadruple therapy with sequential therapy, the eradication rate was not significant between groups (86.9% vs 86.0%). However, higher compliance was achieved with concomitant therapy than with sequential therapy.
CONCLUSION: The H. pylori eradication rate was higher for nonbismuth concomitant quadruple therapy than for triple therapy. Moreover, higher compliance was achieved with nonbismuth concomitant quadruple therapy than with sequential therapy. Thus, nonbismuth concomitant quadruple therapy should be the first-line treatment in Chinese regions.

Abstract
Gastric cancer is the third most common cause of cancer deaths in the world, prompting high-risk countries like South Korea and Japan to establish nationwide screening programmes. Helicobacter pylori is linked to the majority of gastric adenocarcinoma cases and to the vast majority of non-cardia gastric adenocarcinomas. Several studies have demonstrated the effectiveness of 'test-and-treat' programmes for H. pylori infection to prevent gastric cancer in high-risk populations. While this strategy has gained momentum, providers in low-risk developed countries may be unaware of the risk individual patients face, particularly those who have emigrated from high-risk regions and members of economically disadvantaged minority groups. Rapidly evolving science in recent years has made it difficult for clinicians to keep up with the current best practices. This article reviews the epidemiology of H. pylori and gastric cancer, screening and diagnostic tests and the current treatment regimens for clinicians.
