Abstract
BACKGROUND Standard triple therapy is commonly prescribed Helicobacter pylori eradication regimen in Europe. However, the world is witnessing declines in eradication success. It is crucial to find better treatment options. AIMS To evaluate efficacy, compliance and side effects of H. pylori eradication treatment by adding Saccharomyces boulardii . METHODS We conducted a randomized clinical trial within the GISTAR cohort, consisting of healthy individuals aged 40-64 years. Participants were administered clarithromycin-containing triple therapy (clarithromycin 500 mg, amoxicillin 1000 mg, esomeprazole 40 mg) twice daily. Randomization was applied based on two factors: 1)addition of Saccharomyces boulardii CNCM I-745 500 mg BID or not; 2)treatment duration of 10 or 14 days. Treatment completion and adverse events were assessed via telephone interview 21-28 days after medication delivery. The efficacy was evaluated using a 13C-urea breath test (UBT) six months after treatment. RESULTS Altogether 404 participants were enrolled; data on adverse events were available from 391. Overall, 286 participants received follow-up UBT. Intention-to-treat analysis revealed higher eradication rates for 10-day probiotic treatment (70.8% vs. 54.6%, P = 0.022), but not for 14-day. Probiotic subgroups combined showed non-significantly higher efficacy in per-protocol analysis (90.6% vs. 85.0%, P = 0.183). S. boulardii reduced the frequency of adverse events ( P = 0.033) in 14-day regimen, particularly treatment-associated diarrhea ( P = 0.032). However, after the adjustment to control Type I error, results lost their significance. CONCLUSION Addition of S. boulardii to 14-day clarithromycin-containing triple regimen non-significantly lowers the likelihood of diarrhea and does not increase the eradication rate.

Abstract
Helicobacter pylori (H. pylori) causes infection in the stomach and is a major factor for gastric carcinogenesis. The application of antimicrobial peptides (AMPs) as an alternative treatment to traditional antibiotics is limited by their facile degradation in the stomach, their poor penetration of the gastric mucosa, and the cost of peptide production. Here, the design and characterization of a genetically encoded H. pylori-responsive microbicidal protein crystal Cry3Aa-MIIA-AMP-P17 is described. This designed crystal exhibits preferential binding to H. pylori, and when activated, promotes the targeted release of the AMP at the H. pylori infection site. Significantly, when the activated Cry3Aa-MIIA-AMP-P17 crystals are orally delivered to infected mice, the Cry3Aa crystal framework protects its cargo AMP against degradation, resulting in enhanced in vivo efficacy against H. pylori infection. Notably, in contrast to antibiotics, treatment with the activated crystals results in minimal perturbation of the mouse gut microbiota. These results demonstrate that engineered Cry3Aa crystals can serve as an effective platform for the oral delivery of therapeutic peptides to treat gastrointestinal diseases.

Wang Y, Wang X, Cao XY, Zhu HL, Miao L. Comparative effectiveness of different probiotics supplements for triple helicobacter pylori eradication: a network meta-analysis. Front Cell Infect Microbiol 2023; 13:1120789. [PMID: 37256113 PMCID: PMC10226649 DOI: 10.3389/fcimb.2023.1120789] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Accepted: 04/24/2023] [Indexed: 06/01/2023] Open
Abstract
Background Probiotics has been reported as an effective supplement for Helicobacter pylori eradication. However, knowledge of their comparative efficacy is still lacking. Aim In this study, we used network meta-analysis of current probiotics supplement used in standard triple therapy to assess and rank their comparative effectiveness. Methods All randomized controlled trials from three main databases (PubMed, Embase and Cochrane Library) up to April 2022 were collected and filtered to meet our criterion. We used Bayesian network meta-analysis to evaluate the eligible randomized controlled trials and gave a rank for the efficiency and incidence of side effects of each probiotics supplement. The ranking probability for each therapy was assessed by means of surfaces under cumulative ranking values. Subgroup analysis was conducted to evaluate other possible influencing factors. Results 34 eligible randomized controlled trials entered the following meta-analysis, including 9,004 patients randomized to 10 kinds of therapies. Result showed that most probiotics added therapies had better outcomes than triple therapy, among which Bifidobacterium-Lactobacillus and Bifidobacterium-Lactobacillus-Saccharomyces adjuvant therapy could obtain comprehensive benefit with high eradication rate (78.3% and 88.2% respectively), and cause few side effects. Combination of different probiotics, adding probiotics before or after triple therapy and longer duration of probiotics can improve therapeutic effect in H.pylori infected individuals. Conclusion For triple therapy of H.pylori infection, adding probiotics can increase eradication rate and bring protective effect. Considering the overall influence, Bifidobacterium-Lactobacillus or Bifidobacterium-Lactobacillus-Saccharomyces therapy can be a better choice in improving H.pylori eradication process.

Therap Adv Gastroenterol 2023; 16:17562848221147763. [PMID: 36742013 PMCID: PMC9893347 DOI: 10.1177/17562848221147763] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 12/11/2022] [Indexed: 01/30/2023] Open
Abstract
Background We previously reported that antofloxacin-based bismuth quadruple therapy was safe and effective for Helicobacter pylori (H. pylori) eradication. It is not clear whether the addition of Saccharomyces boulardii (S. boulardii) to antofloxacin-based quadruple therapy can improve the eradication rate of H. pylori and reduce adverse events. Objective To investigate the effect of adding S. boulardii to antofloxacin-based quadruple therapy on the eradication rate of H. pylori and the adverse events. Design Single-center, prospective randomized controlled study. Methods A total of 172 patients with H. pylori infection were randomly assigned to the test and control groups. Patients in the control group (n = 86) received antofloxacin-based bismuth quadruple therapy for 14 days. On this basis, cases in the test group (n = 86) received S. boulardii 500 mg b.i.d. The eradication rate of H. pylori and adverse events were observed 4 weeks after the treatment. Results There were no statistically significant differences in the eradication rates of H. pylori and frequency of diarrhea between the test group and control group (p > 0.05). The duration of diarrhea in the test group was significantly shorter than in the control group (p < 0.001). In addition, the two groups exhibited similar adverse event rates for epigastric pain, abdominal distention, dizzy, vomiting, and rash (p > 0.05). The severity of adverse reactions was similar between the two groups (p > 0.05), and most of them had mild adverse events. Conclusion Although the addition of S. boulardii to antofloxacin-based quadruple therapy could not improve the eradication rate of H. pylori, it could shorten the time of antibiotic-associated diarrhea and reduce the incidence of diarrhea. Trial registration number ChiCTR2200056931.

Abstract
Background: Whether probiotics helped the Helicobacter pylori (H. pylori) eradication was still highly controversial. The non-bacterial Saccharomyces boulardii (S. boulardii) has demonstrated its efficacy in the treatment of antibiotic-associated and infectious diarrhea. We aimed to evaluate the effects of S. boulardii combined with quadruple therapy for H. pylori eradication and associated side effects. Methods: Three hundred and sixty H. pylori-infected patients were recruited in this multicenter, randomized controlled trial. The patients who underwent H. pylori eradication treatment were randomized in a ratio of 1:1 into two separate groups that received standard quadruple therapy (Group A) and quadruple therapy plus S. boulardii sachets (Group B) for 14 days. The everyday medication and side-effect records were collected for compliance and adverse effect analysis. All patients accepted 13C/14C-urea breath tests 4 weeks after the therapy completion. Results:Saccharomyces boulardii and quadruple therapy-combined intervention significantly reduced the incidences of overall side effects (27.8 vs. 38.5%, p = 0.034) and diarrhea (11.2 vs. 21.2%, p = 0.012) in Group B compared with quadruple therapy alone in Group A, especially reduced the diarrhea duration (5.0 days vs. 7.7 days, p = 0.032) and incidence of severe diarrhea (4.7 vs. 10.1%, p = 0.040). Intention-to-treat (ITT) analysis and per-protocol (PP) analysis both indicated no statistical differences of eradication rate between Groups A and B (ITT: 82.7 vs. 85.8%, p = 0.426; PP: 89.7 vs. 94.2%, p = 0.146). The joint use of S. boulardii and quadruple therapy markedly improved the overall pre-eradication alimentary symptoms (hazard ratio (HR): 2.507, 95% CI: 1.449–4.338) recovery. Conclusion:Saccharomyces boulardii ameliorated H. pylori eradication-induced antibiotic-associated side effects especially reduced the incidence of severe diarrhea and the duration of diarrhea. However, there was no significant effect of S. boulardii on the rate of H. pylori eradication.

Abstract
Saccharomyces cerevisiae var. boulardii (S. boulardii) has been isolated from lychee (Litchi chinensis), mangosteen fruit, kombucha, and dairy products like kefir. Dairy products containing S. boulardii have been revealed to possess potential probiotic activities owing to their ability to produce organic acids, essential enzymes, vitamins, and other important metabolites such as vanillic acid, phenyl ethyl alcohol, and erythromycin. S. boulardii has a wide spectrum of anti-carcinogenic, antibacterial antiviral, and antioxidant activity, and is known to reduce serum cholesterol levels. However, this yeast has mainly been prescribed for prophylaxis treatment of gastrointestinal infectious diseases, and stimulating the immune system in a number of commercially available products. The present comprehensive review article reviews the properties of S. boulardii related to their use in fermented dairy foods as a probiotic microorganism or starter culture. Technical aspects regarding the integration of this yeast into the dairy foods matrix its health advantages, therapeutic functions, microencapsulation, and viability in harsh conditions, and safety aspects are highlighted.

Abstract
Helicobacter pylori infection is one of the most common infectious diseases worldwide. H. pylori is responsible for substantial gastrointestinal morbidity with a high disease burden. Since the revision of the H. pylori Clinical Practice Guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin based triple therapy. According to a nationwide randomized controlled study by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance to clarithromycin. The clinical practice guidelines for treatment of H. pylori were updated based on evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after expert consensus on three recommendations regarding the indication for treatment and eight recommendations on the treatment itself. These guidelines were designed to provide clinical evidence for the treatment of H. pylori to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards, and will be revised if more evidence emerges in the future.

Abstract
Helicobacter pylori infection is one of the most common infectious diseases worldwide. Although the prevalence of H. pylori is gradually decreasing, approximately half of the world's population still becomes infected with this disease. H. pylori is responsible for substantial gastrointestinal morbidity worldwide, with a high disease burden. It is the most common cause of gastric and duodenal ulcers and gastric cancer. Since the revision of the H. pylori clinical practice guidelines in 2013 in Korea, the eradication rate of H. pylori has gradually decreased with the use of a clarithromycin-based triple therapy for 7 days. According to a nationwide randomized controlled study conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was mostly due to increased antimicrobial resistance, especially from clarithromycin. The clinical practice guidelines for the treatment of H. pylori were updated according to evidence-based medicine from a meta-analysis conducted on a target group receiving the latest level of eradication therapy. The draft recommendations developed based on the meta-analysis were finalized after an expert consensus on three recommendations regarding the indication for treatment and eight recommendations for the treatment itself. These guidelines were designed to provide clinical evidence for the treatment (including primary care treatment) of H. pylori infection to patients, nurses, medical school students, policymakers, and clinicians. These may differ from current medical insurance standards and will be revised if more evidence emerges in the future.

Abstract
Background/Aims: Standard triple therapy, including a proton pump inhibitor, clarithromycin, and amoxicillin, has been recommended as the first-line for <i>Helicobacter pylori</i> infection. However, the eradication rate of standard triple therapy has declined over the past years because of the increasing resistance to clarithromycin in Korea. We analyzed the eradication rates and the 10-year change in the eradication rates in Korea.Methods: PubMed, EMBASE, the Cochrane Library, and KoreaMed were searched for studies published between January 2007 and June 2018. The pooled eradication rates and their 95% CIs were estimated using a random-effect logistic regression model.Results: Twenty-six randomized controlled studies on standard triple therapy conducted in Korea were selected. The intention-to-treat (ITT) and per protocol analyses showed pooled eradication rates of standard triple therapy of 71.6% (95% CI, 69.9~73.3%) and 79.6% (95% CI, 76.6~82.2%), respectively. The eradication rate decreased with time. The ITT analysis showed that the 14-day therapy (78.1% [95% CI, 75.2~80.7%]) had significantly higher eradication rates than the 7-day therapy (70.0% [95% CI, 68.5~71.4%]) (<i>P</i><0.01).Conclusions: These results suggest that the eradication rate of standard triple therapy, as the first-line therapy, has shown an unacceptable decrease. The eradication rate increased when the duration of therapy was increased to 14 days, but it was not satisfactory. Therefore, other treatment regimens or therapies based on susceptibility tests should be considered for the first-line therapy.

Abstract
Helicobacter pylori (H. pylori) infection is one of the most common infectious diseases worldwide. Although its incidence is gradually decreasing, about half of the world's population still get infected. H. pylori infection is responsible for substantial gastrointestinal morbidity worldwide. It is the most common cause of gastric and duodenal ulcers as well as gastric cancer. Since the revision of the H. pylori Clinical Practice Guidelines in 2013, the eradication rate of H. pylori has gradually decreased with the use of classical triple therapy, wherein amoxicillin, clarithromycin, and proton pump inhibitors are administered, for 7 days. According to a nationwide randomized controlled study conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research released in 2018, the intention-to-treat eradication rate was only 63.9%, which was due to increased antimicrobial resistance induced by the use of antibiotics, especially clarithromycin. The update of clinical practice guideline for treatment of H. pylori was developed based on evidence-based medicine by conducting a meta-analysis. The draft recommendations were finalized after expert consensus on three recommendations regarding the indication for treatment and eight recommendations on the treatment itself. These guidelines are designed to provide patients, nurses, medical school students, policymakers, and clinicians with clinical evidence to guide primary care and treatment of H. pylori infection. These may differ from current medical insurance standards and will be revised further, if necessary, based on research-based evidence.

Abstract
BACKGROUND/AIMS The eradication failure rate of standard triple therapy (proton pump inhibitor, clarithromycin, and amoxicillin) for Helicobacter pylori infection has increased owing to antibiotic resistance in Korea. We assessed whether Saccharomyces boulardii probiotic or broccoli sprout extract sulforaphane supplementation could increase the H. pylori eradication rate and/or reduce antibiotic-associated adverse events. METHODS A total of 217 patients with H. pylori-positive chronic gastritis or peptic ulcer disease were recruited. Clarithromycin resistance was assessed in all patients by testing for A2142G and A2143G point mutations in H. pylori 23S rRNA using a dual-priming polymerase chain reaction (PCR) oligonucleotide. Thirty-four patients (17.3%) were clarithromycin-resistant and were excluded from the study. Finally, 183 patients with infections not resistant to clarithromycin were randomly assigned to triple therapy only (group A, n = 61), triple therapy plus probiotics (group B, n = 61), or triple therapy plus sulforaphane (group C, n = 61) groups. CYP2C19 polymorphisms were examined at position G681A of exon 5 and G636A of exon 4 by PCR with restriction fragment length polymorphism (PCR-RFLP) analysis. H. pylori eradication was assessed by 13C-urea breath test 4 weeks after treatment completion. RESULTS The eradication rates were similar among the groups both in the intention- to-treat (A = 85.2%, B = 89.6%, and C = 81.6%) and per-protocol (A = 89.2%, B = 86.8%, and C = 96.3%) analyses. The frequencies of overall adverse events in the groups also did not differ (A vs. B: p = 0.574; A vs. C: p = 1.000). CONCLUSION Probiotic or sulforaphane with triple therapy for H. pylori infection neither increased the eradication rate nor reduced the occurrence of adverse events.

Abstract
BACKGROUND AND AIMS Whether Saccharomyces boulardii (S boulardii) as an adjuvant therapy are beneficial to H pylori eradication remains controversial. The aim of the study was to update and determine the effects of S boulardii as an adjuvant therapy on H pylori eradication rates and adverse effects. METHODS We searched PubMed, Embase, CENTRAL, and Web of Science to collect all randomized controlled trials assessing the effects of S boulardii as an adjuvant therapy for H pylori eradication from inception to February 2019. Quality of evidence was appraised using Grading of Recommendations, Assessment, Development and Evaluation system. Trial sequential analysis was performed to control the risk of type I and type II errors. RESULTS Eighteen trials with 3592 patients were eligible for meta-analysis. Compared with standard eradication regimen, the S boulardii supplementation could significantly improve eradication rates [risk ratio (RR) = 1.09, 95% confidence interval (CI):1.05-1.13; moderate quality evidence] and reduce the incidence of total side effects (RR = 0.47, 95%CI:0.36-0.61; low quality evidence), as well as some gastrointestinal adverse effects, especially diarrhea (RR = 0.33, 95%CI:0.23-0.47; low quality evidence) and constipation (RR = 0.37, 95%CI:0.23-0.57; moderate quality evidence). In addition, the need for discontinuation rate in S boulardii supplementation group was significantly lower than in the control group (RR = 0.33, 95%CI:0.16-0.69, P = .003; moderate quality evidence). The TSA results for overall eradication rates and total side effects indicated that the effects were conclusive. CONCLUSIONS Our meta-analysis shows that S boulardii supplementation on standard eradication therapy significantly increased H pylori eradication rates and reduced the incidence of total side effects and some gastrointestinal adverse effects during eradication therapy.

Abstract
Introduction: Probiotics are living, non-pathogenic microorganisms (bacteria) that enter through diet in the human body, live during their passage through the gastrointestinal (GI) tract and are beneficial to health. They have become popular in recent years as a way of improving human health through nutrition. This review aims to discuss the efficacy of probiotics for the supportive therapy of certain clinical conditions, especially infectious diseases, as reported in a number of studies, even though some concerns about their safety still remain. Areas covered: This paper will review the history of probiotics, from ancient ages to date, and the evolution of their use in clinical practice. The study is based on both personal professional experience of the authors and a comprehensive literature analysis, including old documents from libraries, searching the related biological and clinical data on Scopus, Web of Science, PubMed, EMBASE, also using the 'cited by' and 'similar articles' options available in PubMed. Expert opinion: Not all researchers agree about the safety and real efficacy of probiotics in common conditions, especially infective diseases. However, the use of probiotics for clinical conditions that may be improved by consumption of these dietary supplements should be considered as a possible supportive therapy in select patients.

Abstract
BACKGROUND Due to decreasing eradication rate and increasing side effects, probiotics have gradually become an important supplement to standard eradication regimens for Helicobacter pylori. OBJECTIVE To evaluate the effectiveness and safety of probiotics in facilitating the eradication of H pylori and to explore the best timing and duration of probiotic supplementation, use of eradication regimens, strains, locations, and common side effects. METHODS Eligible studies were retrieved from the PubMed, EMBASE, Cochrane Library, Web of Science, and CNKI databases, and we applied the Stata 12.0 software for the standard meta-analysis and network meta-analysis. RESULTS Forty eligible studies with 8924 patients were included in the analysis. We used a random-effects model (I = 52.1% and I = 81.4%) to analyze the eradication rate and the incidence of total side effects by intention to treat (ITT). Compared with the control group, a higher eradication rate (relative risk [RR] 1.140, 95% confidence interval (CI) 1.101-1.180, P < .001) and lower incidence of total side effects (RR 0.470, 95% CI 0.391-0.565, P < .001) were observed in the probiotic group. In the subgroup analysis, we evaluated the surface under the cumulative ranking curve scores for the before + same (75.2%), >2 weeks (92.6%), probiotic + quadruple regimen (99.9%), Lactobacillus (73.6%), multiple strains (72.1%), China (98.5%) groups. The rankings of common side effects are shown in Table 6. SUCRA scores for diarrhea (39.7%), abdominal pain (43.9%), nausea (78.8%), taste disturbance (99.6%), vomiting (7.1%), and constipation (30.9%) were reported. The consistency of all comparison groups was good. CONCLUSIONS Probiotics improved the eradication rate and reduced side effects when added to the treatments designed to eradicate H pylori. The use of probiotics before the eradication treatment and throughout the eradication treatment, and also the use of probiotics for more than 2 weeks, exerted better eradication effects. Probiotics combined with the bismuth quadruple regimen was the best combination. Lactobacillus and multiple strains were better choices of probiotic strains. The eradication effect observed in China was better than the effect observed in other countries.

Comparison of high and low molecular weight chitosan as in-vitro boosting agent for photodynamic therapy against Helicobacter pylori using methylene blue and endoscopic light.

Abstract
BACKGROUND We reported in a previous study that photodynamic therapy (PDT) of Helicobacter pylori(H. pylori) could potentiate bactericidal effect by adding chitosan. As a next step, we compared the bactericidal effects of low molecular weight (LMW) combined with Photodynamic Therapy to high molecular weight (HMW) chitosan. METHOD To perform PDT to kill H. pylori, we used endoscopic light as light source, methylene blue (MB) as a photosensitizer and chitosan (310-375, 50-190 kDa). We evaluated bacterial removal rate and its membrane damage by ethidium bromide monoazide PCR method (EMA q-PCR). 8-oxo-2'-dexoyguanosine by ELISA was measured for oxidative stress. RESULTS At a chitosan concentration of ≤0.05%, the killing effect did not differ between the two molecular weights, and 100% bacterial removal rate was observed at a light energy ≥ 6.23 mJ/cm2 powers under 0.02% MB. After 15 min irradiation, LMW chitosan with high concentration of MB (0.004%) showed highest killing effects, which were consistent with the results of EMA q-PCR but not with the level of 8-OHdG. Bactericidal effects of LMW chitosan plus PDT using 0.002 and 0.004% MB for 15 min irradiation were significantly higher than those using HMW chitosan plus PDT. CONCLUSION We found that PDT using methylene blue with LMW chitosan to kill H. pylori exerted greater bactericidal effects through bacterial membrane damage than PDT with HMW chitosan. These results suggest that it would be better to choose LMW chitosan to enhance the effect of PDT for clinical application, even at a very low concentration of PS.

Abstract
Background/Aims The efficacy of standard triple therapy (STT) in treating Helicobacter pylori infection has decreased. Many investigators have attempted to increase the eradication rate. We investigated the outcomes of concomitant therapy (CT) and STT combined with probiotics (STP) as a first-line treatment for H. pylori infection. Methods We reviewed the medical records of 361 patients who received either STP (n=286) or CT (n=75). The STP group received STT combined with a probiotic preparation for 1 week. The CT group received STT and metronidazole for 1 week. Results The intention-to-treat and per-protocol eradication rates were 83.6% (95% confidence interval [CI], 79.0 to 87.7) and 87.1% (95% CI, 81.2 to 89.7) in the STP group and 86.7% (95% CI, 78.7 to 93.3) and 91.4% (95% CI, 83.6 to 97.1) in the CT group (p=0.512 and p=0.324), respectively. The frequency of adverse effects was higher in the CT group (28.2%) than in the STP group (12.8%) (p=0.002). Conclusions STP and CT are encouragingly efficacious as first-line treatments for H. pylori infection. Therefore, adding probiotics to STT may be a feasible option to avoid side effects.

Abstract
Helicobacter pylori (Hp) is responsible for one of the most common infections in the world. The prevalence exceeds 50% of the population in developing countries, and approximately one-third of the adults are colonized in North Europe and North America. It is considered a major pathogenic agent of chronic gastritis, peptic ulcer, atrophic gastritis, gastric cancer, and mucosa-associated lymphoid tissue lymphoma (MALT). Hp colonization modifies the composition of gastric microbiota that could drive the development of gastric disorders. Currently, an emerging problem in Hp treatment is represented by the increasing rate of antimicrobial therapy resistance. In this context, the search for adjuvant agents can be very useful to overcome this issue and probiotics administration can represent a valid option. The aim of this review is to describe the gastric microbiota changes during Hp colonization, the mechanisms of action, and a possible role of probiotics in the treatment of this infection.

Abstract
Background/Aims The eradication rate of Helicobacter pylori (H. pylori) has been decreasing recently in Korea due to antibiotics resistance. The aim of this study was to investigate the trend of eradication rate and clinical factors affecting the eradication rate of H. pylori in the last 10 years in west Gyeonggi-do, Korea. Methods The trends of eradication rate of H. pylori, gender, age, concomitant mediations, and clinical factors were retrospectively evaluated in patients with H. pylori infection between 2006 and 2015 (n=2,485). Results The overall H. pylori eradication rate for the standard triple therapy was 82.5%. The annual eradication rates from 2006 to 2015 were 90%, 77.9%, 75.8%, 83.2%, 85.6%, 90.1%, 81.3%, 81.1%, 78.7%, and 78.8%, respectively, showing a significant decrement during the last five years (p<0.001). Higher eradication rate was observed in males than in females (p<0.001). Esomeprazole showed a higher eradication rate compared with pantoprazole between 2006 and 2010 (p<0.022). Age and the use of probiotics and mucosal protective agents played no significant role in the H. pylori eradication rate. The overall eradication rate for bismuth-based quadruple therapy was 94.4%. Conclusions The eradication rate of H. pylori over the last 10 years for first-line therapy ranged from 75.8 to 90.1%; the eradication rate for triple therapy has declined. However, the eradication rate for quadruple therapy has remained unchanged over the last 10 years.

Abstract
BACKGROUND The efficacy of Helicobacter pylori eradication regimens may depend on the country where the studies were performed because of the difference in antibiotic resistance. We aimed to analyze the efficacy of H. pylori eradication regimens in Korea where clarithromycin resistance rate is high. METHODS We searched for all relevant randomized controlled trials published until November 2016 that investigated the efficacy of H. pylori eradication therapies in Korea. A network meta-analysis was performed to calculate the direct and indirect estimates of efficacy among the eradication regimens. RESULTS Forty-three studies were identified through a systematic review, of which 34 studies, published since 2005, were included in the meta-analysis. Among 21 included regimens, quinolone-containing sequential therapy for 14 days (ST-Q-14) showed the highest eradication rate (91.4% [95% confidence interval [CI], 86.9%-94.4%] in the intention-to-treat [ITT] analysis). The eradication rate of the conventional triple therapy for 7 days, standard sequential therapy for 10 days, hybrid therapy for 10-14 days, and concomitant therapy for 10-14 days was 71.1% (95% CI, 68.3%-73.7%), 76.2% (95% CI, 72.8%-79.3%), 79.4% (95% CI, 75.5%-82.8%), and 78.3% (95% CI, 75.3%-80.9%), respectively, in the ITT analysis. In the network meta-analysis, ST-Q-14 showed a better comparative efficacy than the conventional triple therapy, standard sequential therapy, hybrid therapy, and concomitant therapy. In addition, tolerability of ST-Q-14 was comparable to those regimens. CONCLUSION In Korea, ST-Q-14 showed the highest efficacy in terms of eradication and a comparable tolerability, compared to the results reported for the conventional triple therapy, standard sequential therapy, hybrid therapy, and concomitant therapy.

Abstract
Aim: We aimed to evaluate the role of the addition of Bifidobacterium /actis-containing synbiotic to the triple therapy in the case of He/icobacter py/ori eradication, the dyspeptic symptoms, and reducing the side effects of antibiotics. Materials and methods: A total of 104 children aged between 5 and 17 years, who were histopathologically diagnosed with H. py/ori were enrolled in this study, of whom 100 were included in the analysis. Patients were randomly classified into two groups. In the first group, 50 patients were administered amoxicillin + clarithromycin + lansoprazole for 14 days and B. /actis-containing synbiotic. In the second group, 50 patients were treated with the standard triple therapy. All patients were given information after completion of therapy. Results: H. py/ori eradication was achieved in 88% in group I who received standard therapy with additional synbiotic and 72% in group II (p = 0.046). The number of patients in the second group who suffered from abdominal pain between the 3rd and 14th day of the treatment was higher (p < 0.05). The addition of probiotics to the triple therapy significantly reduced the frequency of diarrhea, but no significant difference was detected in the frequency of metallic taste (p = 0.04, p = 0.418 respectively). Conclusion: The addition of synbiotic to the triple therapy is effective for eradicating H. py/ori infection in children and is usually helpful to reduce or eliminate dyspeptic symptoms like abdominal pain, diarrhea, and vomiting. This study suggest that improved tolerance to the eradication treatment also reduces the treatment failure by adding probiotics and encourages the future study using probiotic supplementation in H. py/ori treatment.

Abstract
Over 80% of individuals infected with Helicobacter pylori (H. pylori) are asymptomatic. Increased resistance to antibiotics and decreased compliance to the therapeutic regimens have led to the failure of eradication therapy. Probiotics, with direct and indirect inhibitory effects on H. pylori in both animal models and clinical trials, have recently been used as a supplementary treatment in H. pylori eradication therapy. Probiotics have been considered useful because of the improvements in H. pylori eradication rates and therapy-related side effects although treatment outcomes using probiotics are controversial due to the heterogeneity of species, strains, doses and therapeutic duration of probiotics. Thus, despite the positive role of probiotics, several factors need to be further considered during their applications. Moreover, adverse events of probiotic use need to be noted. Further investigations into the safety of adjuvant probiotics to H. pylori eradication therapy are required.

Abstract
Although the global prevalence of peptic ulcer disease (PUD) is decreasing, PUD is still one of the most common upper gastrointestinal diseases in the world due to Helicobacter pylori infection and increased use of non-steroidal anti-inflammatory drugs. In Korea, the prevalence of H. pylori infection is also declining, but it is still the major cause of PUD. The outcomes of H. pylori infection are caused by imbalances between bacterial virulence factors, host factors, and environmental influences. In this review, we describe the prevalence trends of H. pylori infection in Korea, the mechanism of H. pylori infection-related PUD, and treatment strategies.

Abstract
Introduction Helicobacter pylori colonization is present in half of the world’s population and can lead to numerous gastrointestinal diseases if left untreated, including peptic ulcer disease and gastric cancer. Although concurrent triple therapy remains the recommended treatment regimen for H. pylori eradication, its success rate and efficacy have been declining. Recent studies have shown that the addition of probiotics can significantly increase eradication rates by up to 50%. This meta-analysis examines the impact of probiotic supplementation on the efficacy of standard triple therapy in eradicating H. pylori. Methods A comprehensive literature search was conducted using PubMed, Cochrane Central Registry of Controlled Trials, and Google Scholar (time of inception to 2016) to identify all published randomized control trials (RCTs) assessing the use of probiotics in addition to triple therapy for the treatment of H. pylori. Searches were conducted using the keywords “probiotics”, “triple therapy”, and “Helicobacter pylori”. RCTs comparing the use of probiotics and standard triple therapy with standard triple therapy alone for any duration in patients of any age diagnosed with H. pylori infection were included. H. pylori eradication rates (detected using urea breath test or stool antigen) were analyzed as-per-protocol (APP) and intention-to-treat (ITT). Results A total of 30 RCTs involving 4,302 patients APP and 4,515 patients ITT were analyzed. The addition of probiotics significantly increased eradication rates by 12.2% (relative risk [RR] =1.122; 95% confidence interval [CI], 1.091–1.153; P<0.001) APP and 14.1% (RR =1.141; 95% CI, 1.106–1.175; P<0.001) ITT. Probiotics were beneficial among children and adults, as well as Asians and non-Asians. No significant difference was observed in efficacy between the various types of probiotics. The risk of diarrhea, nausea, vomiting, and epigastric pain was also reduced. Conclusion The addition of probiotics is associated with improved H. pylori eradication rates in both children and adults, as well as Asians and non-Asians. Lactobacillus, Bifidobacterium, Saccharomyces, and mixtures of probiotics appear beneficial in H. pylori eradication. Furthermore, the reduction in antibiotic-associated side effects such as nausea, vomiting, diarrhea, and epigastric pain improves medication tolerance and patient compliance. Given the consequences associated with chronic H. pylori infection, the addition of probiotics to the concurrent triple therapy regimen should be considered in all patients with H. pylori infection. However, further studies are required to identify the optimal probiotic species and dose.

Abstract
BACKGROUND
Standard anti-Helicobacter pylori (H. pylori) treatment fails in the eradication of the organism in almost 10-35% of the patients and has different side effects. Recent studies have proposed that probiotic supplementations with or without prebiotic may improve the eradication rate and diminish the side effects, although it is still a controversial issue. We aimed to investigate the effect of probiotic with prebiotic supplementation on the eradication rate and side effects of anti H. pylori quadruple therapy.
METHODS
76 patients with a positive biopsy specimen for H. pylori were enrolled. They were randomized to receive quadruple therapy of bismuth, clarithromycin, amoxicillin, and omeprazole for 14 days and also the synbiotic or the placebo. We asked them to answer study questionnaires at the beginning and during the treatment. Finally, urea breath test was done 8 weeks after the treatment.
RESULTS
The eradication rate was significantly better in the synbiotic group by intention-to-treat analysis (p<0.05). Treatment side effects such as diarrhea, nausea, vomiting, epigastric pain, flatulence, constipation, and taste abnormality were similar in both groups but anorexia was significantly better in the synbiotic group (p <0.05).
CONCLUSION
The eradication rate was significantly better in the synbiotic group by intention-to-treat analysis (p<0.05). Treatment side effects such as diarrhea, nausea, vomiting, epigastric pain, flatulence, but could improve the eradication by augmenting the treatment tolerance and compliance.

Probiotic supplementation does not improve eradication rate of Helicobacter pylori infection compared to placebo based on standard therapy: a meta-analysis. Sci Rep 2016; 6:23522.

Abstract
This meta-analysis included eligible randomized controlled trials (RCTs) with the aim of determining whether probiotic supplementation can improve H. pylori eradication rates. PUBMED, EBSCO, Web of Science, and Ovid databases were searched. We included RCTs that investigated the effect of combining probiotics, with or without a placebo, with standard therapy. A total of 21 RCTs that reported standard therapy plus probiotics were included. Compared to the placebo group, the probiotics group was 1.21(OR 1.21, 95% CI: 0.86, 1.69) and 1.28 (OR 1.28, 95% CI: 0.88, 1.86) times more likely to achieve eradication of H. pylori infection in intent-to-treat (ITT) analysis and per protocol (PP) analysis, respectively. Probiotics with triple therapy plus a 14-day course of treatment did not improve the eradication of H. pylori infection (OR 1.44, 95% CI: 0.87, 2.39) compared to the placebo. Moreover, the placebo plus standard therapy did not improve eradication rates compared to standard therapy alone (P = 0.816). However, probiotics did improve the adverse effects of diarrhea and nausea. These pooled data suggest that the use of probiotics plus standard therapy does not improve the eradication rate of H. pylori infection compared to the placebo.

Abstract
Infection with the Gram-negative pathogen Helicobacter pylori (H. pylori) has been associated with gastro-duodenal disease and the importance of H. pylori eradication is underscored by its designation as a group I carcinogen. The standard triple therapy consists of a proton pump inhibitor, amoxicillin and clarithromycin, although many other regimens are used, including quadruple, sequential and concomitant therapy regimens supplemented with metronidazole, clarithromycin and levofloxacin. Despite these efforts, current therapeutic regimens lack efficacy in eradication due to antibiotic resistance, drug compliance and antibiotic degradation by the acidic stomach environment. Antibiotic resistance to clarithromycin and metronidazole is particularly problematic and several approaches have been proposed to overcome this issue, such as complementary probiotic therapy with Lactobacillus. Other studies have identified novel molecules with an anti-H. pylori effect, as well as tailored therapy and nanotechnology as viable alternative eradication strategies. This review discusses current antibiotic therapy for H. pylori infections, limitations of this type of therapy and predicts the availability of newly developed therapies for H. pylori eradication.

Abstract
The presence of concomitant diseases is an independent predictive factor for non-Helicobacter pylori (H. pylori) peptic ulcers. Patients contracting concomitant diseases have an increased risk of developing ulcer disease through pathogenic mechanisms distinct from those of H. pylori infections. Factors other than H. pylori seem critical in peptic ulcer recurrence in end stage renal disease (ESRD) and cirrhotic patients. However, early H. pylori eradication is associated with a reduced risk of recurrent complicated peptic ulcers in patients with ESRD and liver cirrhosis. Resistances to triple therapy are currently detected using culture-based and molecular methods. Culture susceptibility testing before first- or second-line therapy is unadvisable. Using highly effective empiric first-line and rescue regimens can yield acceptable results. Sequential therapy has been included in a recent consensus report as a valid first-line option for eradicating H. pylori in geographic regions with high clarithromycin resistance. Two novel eradication regimens, namely concomitant and hybrid therapy, have proven more effective in patients with dual- (clarithromycin- and metronidazole-) resistant H. pylori strains. We aim to review the prevalence of and eradication therapy for H. pylori infection in patients with ESRD and cirrhosis. Moreover, we summarized the updated H. pylori eradication regimens.

Abstract
Helicobacter pylori (H. pylori) is considered an etiologic factor for the development of peptic ulcer disease, gastric adenocarcinoma, and MALT lymphoma. Therapeutic schemes to eradicate the bacteria are based on double antibiotic therapy and proton pump inhibitor. Despite many therapeutic improvements in H. pylori eradication treatment, it is still associated with high infection rate also in developed countries. Bacterial resistance and adverse events occurrence are among most frequent causes for anti- H. pylori treatment failure. Several studies have reported that certain probiotic strains can exhibit inhibitory activity against H. pylori bacteria. In addition, some probiotic strains can reduce the occurrence of side effects due to antibiotic therapy and consequently increase the H. pylori eradication rate. The results of the prospective double-blind placebo-controlled studies suggest that specific probiotics, such as S. boulardii and L. johnsonni La1 probably can diminish the bacterial load, but not completely eradicate the H. pylori bacteria. Furthermore, it seems that supplementation with S. boulardii is a useful concomitant therapy in the standard H. pylori eradication treatment protocol and most probably increases eradication rate. L. reuteri is equally effective, but more positive studies are needed. Finally, probiotic strains, such as S. boulardii, L. reuteri and L. GG, decrease gastrointestinal antibiotic associated adverse effects.

Abstract
BACKGROUND Antibiotic-associated diarrhoea is a common complication of antibiotic use, but it can be prevented with administration of probiotics. AIM To update our 2005 meta-analysis on the effectiveness of Saccharomyces boulardii in preventing antibiotic-associated diarrhoea in children and adults. METHODS The Cochrane Library, MEDLINE, and EMBASE databases were searched up until May 2015, with no language restrictions, for randomised controlled trials; additional references were obtained from reviewed articles. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidelines. RESULTS Twenty-one randomised controlled trials (4780 participants), among which 16 were new trials, met the inclusion criteria for this updated systematic review. Administration of S. boulardii compared with placebo or no treatment reduced the risk of antibiotic-associated diarrhoea (as defined by the study investigators) in patients treated with antibiotics from 18.7% to 8.5% (risk ratio, RR: 0.47; 95% CI: 0.38-0.57, number needed to treat, NNT: 10; 95% CI: 9-13). In children, S. boulardii reduced the risk from 20.9% to 8.8% (6 randomised controlled trials, n=1653, RR: 0.43, 95% CI: 0.3-0.6); in adults, from 17.4% to 8.2% (15 randomised controlled trials, n=3114, RR: 0.49, 95% CI: 0.38-0.63). Moreover, S. boulardii reduced the risk of Clostridium difficile-associated diarrhoea; however, this reduction was significant only in children (2 randomised controlled trials, n = 579, RR: 0.25; 95% CI: 0.08-0.73) and not in adults (9 randomised controlled trials, n = 1441, RR: 0.8, 95% CI: 0.47-1.34). CONCLUSIONS This meta-analysis confirms that S. boulardii is effective in reducing the risk of antibiotic-associated diarrhoea in children and adults.

Abstract
OBJECTIVE To determine the most efficacious treatment for eradication of Helicobacter pylori with the lowest likelihood of some common adverse events among pre-recommended and newer treatment regimens. DESIGN Systematic review and network meta-analysis. DATA SOURCES Cochrane Library, PubMed, and Embase without language or date restrictions. STUDY SELECTION Full text reports of randomised controlled trials that compared different eradication treatments for H pylori among adults. RESULTS Of the 15,565 studies identified, 143 were eligible and included. Data on 14 kinds of treatments were available. Of 91 possible comparisons for the efficacy outcome, 34 were compared directly and the following treatments performed better: seven days of concomitant treatment (proton pump inhibitor and three kinds of antibiotics administered together), 10 or 14 days of concomitant treatment, 10 or 14 days of probiotic supplemented triple treatment (standard triple treatment which is probiotic supplemented), 10 or 14 days of levofloxacin based triple treatment (proton pump inhibitor, levofloxacin, and antibiotic administered together), 14 days of hybrid treatment (proton pump inhibitor and amoxicillin used for seven days, followed by a proton pump inhibitor, amoxicillin, clarithromycin, and 5-nitroimidazole for another seven days), and 10 or 14 days of sequential treatment (five or seven days of a proton pump inhibitor plus amoxicillin, followed by five or seven additional days of a proton pump inhibitor plus clarithromycin and 5-nitroimidazole or amoxicillin). In terms of tolerance, all treatments were considered tolerable, but seven days of probiotic supplemented triple treatment and seven days of levofloxacin based triple treatment ranked best in terms of the proportion of adverse events reported. CONCLUSION Comparison of different eradication treatments for H pylori showed that concomitant treatments, 10 or 14 days of probiotic supplemented triple treatment, 10 or 14 days of levofloxacin based triple treatment, 14 days of hybrid treatment, and 10 or 14 days of sequential treatment might be better alternatives for the eradication of H pylori.

Abstract
AIM: To evaluate the relevant systematic reviews/meta-analyses that focused on probiotics as adjunctive therapy for Helicobacter pylori (H. pylori) infection.
METHODS: The systematic reviews/meta-analyses on probiotics as adjunctive therapy for H. pylori infection were searched in CBM, CNKI, Wanfang database, VIP Database, the Cochrane library, PubMed and Embase from inception to October 2014. Two reviewers screened the literature according to the inclusion criteria and extracted the data. The Overview Quality Assessment Questionnaire (OQAQ) was used to evaluate the quality of the included studies, and the GRADE system was used to evaluate the quality of evidence.
RESULTS: A total of 11 relevant meta-analyses were included, all of which evaluated the rate of H. pylori eradication and incidence of overall side effects (three evaluated the anti-H. pylori therapy-related side effects in detail). The mean OQAQ score was 3.82. Based on the GRADE system, the evidence quality was generally low.
CONCLUSION: Probiotics as adjunctive therapy for H. pylori infection have certain advantages, however, the overall quality of meta-analyses is poor, and the evidence level is low. Physicians should make an evidence-based decision according to the real condition.

Abstract
Helicobacter pylori is one of the most commonly seen bacterium worldwide. It’s in the etiology of multiple gastrointestinal diseases, ranging from gastritis to gastric carcinoma. The antimicrobial therapies, which are frequently prescribed empirically, are losing their effectivity as a result of the increasing antimicrobial resistance. As the standard triple therapy is now left especially in areas with high-clarithromycin resistance due to decreased eradication rates, quadruple therapies are recommended in most regions of the world. Alternatively, concomitant, sequential and hybrid therapies are used. There is still a debate going on about the use of levofloxacin-based therapy in order to prevent the increase in quinolone resistance. If no regimen can achieve the desired eradication rate, culture-guided individualized therapies are highly recommended. Probiotics, statins and n-acetylcysteine are helpful as adjuvant therapies in order to increase the effectiveness of the eradication therapy. Herein, we focused on different eradication regimens in order to highlight the current Helicobacter pylori treatment.

Abstract
We review herein the basis for using dietary components to treat and/or prevent Helicobacter pylori infection, with emphasis on (a) work reported in the last decade, (b) dietary components for which there is mechanism-based plausibility, and (c) components for which clinical results on H pylori amelioration are available. There is evidence that a diet-based treatment may reduce the levels and/or the virulence of H pylori colonization without completely eradicating the organism in treated individuals. This concept was endorsed a decade ago by the participants in a small international consensus conference held in Honolulu, Hawaii, USA, and interest in such a diet-based approach has increased dramatically since then. This approach is attractive in terms of cost, treatment, tolerability, and cultural acceptability. This review, therefore, highlights specific foods, food components, and food products, grouped as follows: bee products (eg, honey and propolis); probiotics; dairy products; vegetables; fruits; oils; essential oils; and herbs, spices, and other plants. A discussion of the small number of clinical studies that are available is supplemented by supportive in vitro and animal studies. This very large body of in vitro and preclinical evidence must now be followed up with rationally designed, unambiguous human trials.

Abstract
BACKGROUND Unsatisfactory Helicobacter pylori eradication rates and therapy-associated side effects remain a problem. AIM To update our 2010 meta-analysis on the effects of Saccharomyces boulardii as supplementation to a standard eradication regimen on H. pylori eradication rates and therapy-associated side effects. METHODS The Cochrane Library, MEDLINE and EMBASE databases were searched from July 2010 (end date of last search) to February 2015, with no language restrictions, for randomised controlled trials (RCTs); additional references were obtained from reviewed articles. Quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines. RESULTS Eleven RCTs (2200 participants, among them 330 children) met the inclusion criteria. Of the 853 patients in the S. boulardii group, 679 (80%, 95% CI 77-82) experienced eradication compared with 608 of the 855 patients (71%, 95% CI 68-74) in the control group [relative risk (RR) 1.11, 95% confidence interval (CI) 1.06-1.17; moderate quality evidence]. S. boulardii compared with control reduced the risk of overall H. pylori therapy-related adverse effects (RR 0.44, 95% CI 0.31-0.64; moderate quality evidence), particularly of diarrhoea (RR 0.51, 95% CI 0.42-0.62; high quality evidence) and nausea [RR 0.6, 95% CI 0.44-0.83 (moderate quality of evidence)]. CONCLUSIONS In the populations studied, the effectiveness of standard triple therapy was unsatisfactory. The addition of S. boulardii significantly increased the eradication rate, but it was still below the desired level of success. Saccharomyces boulardii significantly decreased some therapy-related side effects.

Abstract
AIM: To summarize the evidence from randomized controlled trials (RCTs) regarding the effect of probiotics by using a meta-analytic approach.
METHODS: In July 2013, we searched PubMed, EMBASE, Ovid, the Cochrane Library, and three Chinese databases (Chinese Biomedical Literature Database, Chinese Medical Current Content, and Chinese Scientific Journals database) to identify relevant RCTs. We included RCTs investigating the effect of a combination of probiotics and standard therapy (probiotics group) with standard therapy alone (control group). Risk ratios (RRs) were used to measure the effect of probiotics plus standard therapy on Helicobacter pylori (H. pylori) eradication rates, adverse events, and patient compliance using a random-effect model.
RESULTS: We included data on 6997 participants from 45 RCTs, the overall eradication rates of the probiotic group and the control group were 82.31% and 72.08%, respectively. We noted that the use of probiotics plus standard therapy was associated with an increased eradication rate by per-protocol set analysis (RR = 1.11; 95%CI: 1.08-1.15; P < 0.001) or intention-to-treat analysis (RR = 1.13; 95%CI: 1.10-1.16; P < 0.001). Furthermore, the incidence of adverse events was 21.44% in the probiotics group and 36.27% in the control group, and it was found that the probiotics plus standard therapy significantly reduced the risk of adverse events (RR = 0.59; 95%CI: 0.48-0.71; P < 0.001), which demonstrated a favorable effect of probiotics in reducing adverse events associated with H. pylori eradication therapy. The specific reduction in adverse events ranged from 30% to 59%, and this reduction was statistically significant. Finally, probiotics plus standard therapy had little or no effect on patient compliance (RR = 0.98; 95%CI: 0.68-1.39; P = 0.889).
CONCLUSION: The use of probiotics plus standard therapy was associated with an increase in the H. pylori eradication rate, and a reduction in adverse events resulting from treatment in the general population. However, this therapy did not improve patient compliance.

Exp Ther Med 2015; 9:707-716. [PMID: 25667617 PMCID: PMC4316960 DOI: 10.3892/etm.2015.2174] [Citation(s) in RCA: 60] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2014] [Accepted: 12/05/2014] [Indexed: 12/14/2022] Open
Abstract
The aim of the present study was to determine whether probiotics could help to improve the eradication rates and reduce the side effects associated with anti-Helicobacter pylori treatment, and to investigate the optimal time and duration of probiotic administration during the treatment, thus providing clinical practice guidelines for eradication success worldwide. By searching Pubmed, Embase, the Cochrane Central Register of Controlled Trials and the Science Citation Index, all the randomized controlled trials (RCTs) comparing probiotics as adjuvant agents of anti-H. pylori standard triple-therapy regimens with placebo or no treatment were selected. Statistical analysis was performed with the Comprehensive Meta Analysis Software. Subgroup, meta-regression and sensitivity analyses were also carried out. Twenty-one RCTs involving a total of 3,814 participants met the inclusion criteria. The pooled eradication rates of the probiotic group were 80.3% (1,709/2,128) by intention-to-treat (ITT) and 83.8% (1,709/2,039) by pro-protocol analyses; the pooled relative risk (RR) by ITT for probiotic supplementation versus treatment without probiotics was 1.12 [95% confidence interval (CI), 1.06-1.19]. A reduced risk of overall H. pylori therapy-related adverse effects was also found with probiotic supplementation (RR, 0.60; 95% CI, 0.40-0.91). The subgroup analyses showed that probiotic supplementation prior and subsequent to the treatment regimen both improved eradication rates for H. pylori infection. Furthermore, probiotic treatment lasting >2 weeks and including Lactobacillus or multiple probiotic strains significantly enhanced the efficacy. In conclusion, supplementation with probiotics for H. pylori eradication may be effective in increasing eradication rates and decreasing therapy-related side effects. Probiotic administration prior or subsequent to therapy and for a duration of >2 weeks may increase the eradication efficacy.

Abstract
AIM: To evaluate the role of probiotics in the standard triple Helicobacter pylori therapy.
METHODS: In this meta-analysis, we investigated the efficacy of probiotics in a standard triple H. pylori therapy in adults. Searches were mainly conducted in MEDLINE/PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials. Fourteen studies met our criteria, and the quality of these studies was assessed using the Jadad scale. We used STATA version 12.0 to extract data and to calculate the odds ratios (ORs), which are presented with the corresponding 95% confidence intervals (CIs). The data are presented as forest plots.
RESULTS: The pooled ORs for the eradication rates calculated by intention-to-treat analysis and per-protocol analysis in the probiotic group vs the control group were 1.67 (95%CI: 1.38-2.02) and 1.68 (95%CI: 1.35-2.08), respectively, using the fixed-effects model. The sensitivity of the Asian studies was greater than that of the Caucasian studies (Asian: OR = 1.78, 95%CI: 1.40-2.26; Caucasian: OR = 1.48, 95%CI: 1.06-2.05). The pooled OR for the incidence of total adverse effects was significantly lower in the probiotic group (OR = 0.49, 95%CI: 0.26-0.94), using the random effects model, with significant heterogeneity (I2 = 85.7%). The incidence of diarrhea was significantly reduced in the probiotic group (OR = 0.21, 95%CI: 0.06-0.74), whereas the incidence of taste disorders, metallic taste, vomiting, nausea, and epigastric pain did not differ significantly between the probiotic group and the control group.
CONCLUSION: Supplementary probiotic preparations during standard triple H. pylori therapy may improve the eradication rate, particularly in Asian patients, and the incidence of total adverse effects.

Abstract
Background Previous meta-analyses reported that probiotics improve the effectiveness of Helicobacter pylori (H. pylori) eradication during antibiotic therapy, while results regarding a possible reduction of side effects remained inconclusive. Moreover, the effectiveness of different strains of probiotics has not been studied so far. It is further conceivable that probiotics will produce additional effects only if antibiotics are relatively ineffective. Methods This meta-analysis includes eligible randomized controlled trials examining effects of probiotics supplementation on eradication rates (ER) and side effects, published up to May 2014. Sub-group analysis was performed to compare different probiotic strains and antibiotic therapies with different effectiveness in controls (ER <80% vs.>80%). Publication bias was assessed with funnel plots and Harbord's test. The quality of the trials was assessed with the Cochrane risk of bias tool. Results Thirty-three RCTs involving a total of 4459 patients met the inclusion criteria in case of eradication rates of which 20 assessed total side effects in addition. Overall, the pooled eradication rate in probiotics supplementation groups was significantly higher than in controls (ITT analysis: RR 1.122, 95% CI 1.086–1.159, PP analysis: RR 1.114, 95% CI 1.070–1.159). Sub group-analysis could, however, confirm this finding only for four individual strains (Lactobacillus acidophilus, Lactobacillus casei DN-114001, Lactobacillus gasseri, and Bifidobacterium infantis 2036) and for relatively ineffective antibiotic therapies. There was a significant difference between groups in the overall incidence of side effects (RR 0.735, 95% CI 0.598–0.902). This result was, however, only confirmed for non-blinded trials. Conclusions The pooled data suggest that supplementation with specific strains of probiotics compared with eradication therapy may be considered an option for increasing eradication rates, particularly when antibiotic therapies are relatively ineffective. The impact on side effects remains unclear and more high quality trials on specific probiotic strains and side effects are thus needed.

Abstract
AIM: To compare the efficacy and safety of Bifico combined with triple therapy vs bismuth containing quadruple therapy in the management of Helicobacter pylori (H. pylori) positive peptic ulcer.
METHODS: One hundred and fifty patients with H. pylori positive peptic ulcer were randomly divided into three groups: A, B and C. Group A was treated with rabeprazole, amoxicillin, and clarithromycin, group B was treated with rabeprazole, amoxicillin, clarithromycin, and colloidal bismuth pectin, and group C was treated with rabeprazole, amoxicillin, clarithromycin, and Bifico. The rate of H. pylori eradication, the incidence of adverse reactions and ulcer healing rate were compared between the three groups.
RESULTS: The rate of H. pylori eradication in groups B (90%) and C (88%) was significantly higher than that in group A (72%) (P < 0.05), but there was no significant difference between groups B and C (P > 0.05). The incidence of adverse reactions in groups A (30%) and B (32%) was significantly higher than that in group C (10%) (P < 0.05), but there was no significant difference between groups A and B (P > 0.05). The ulcer healing rate showed no significant difference among the three groups (group B: 88%; group C: 84%; group A: 78%; P > 0.05).
CONCLUSION: Bifico combined with triple therapy is effective in the treatment of H. pylori positive peptic ulcer, with less adverse reactions and higher ulcer healing rate.

Abstract
INTRODUCTION Saccharomyces boulardii is a well-known probiotic worldwide, and there are numerous studies including experimental and clinical trials in children and adults by the use of S. boulardii. AREAS COVERED The objective of the present report is to provide an update on the evidence for the efficacy of S. boulardii CNCM I-745 in different clinical conditions. Saccharomyces boulardii is one of the best-studied probiotics in acute gastroenteritis (AGE) and is shown to be safe and to reduce the duration of diarrhea and hospitalization by about 1 day. Saccharomyces boulardii is one of the recommended probiotics for AGE in children by European Society of Paediatric Infectious Diseases and European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). Saccharomyces boulardii is also a recommended probiotic for the prevention of antibiotic-associated diarrhea (AAD), and a recent study showed promising results for the treatment of AAD in children. There is insufficient evidence to recommend the long-term use of S. boulardii in patients with irritable bowel syndrome. Although some clinical studies showed positive effects of S. boulardii on inflammation, there is no clinical evidence that S. boulardii is useful in inflammatory bowel disease. Saccharomyces boulardii could be used in patients needing Helicobacter pylori eradication because the S. boulardii improves compliance, decreases the side effects and moderately increases the eradication rate. There are new promising results (improving feeding tolerance, shorten the course of hyperbilirubinemia), but we do still not recommend the routine use of S. boulardii in newborns. EXPERT OPINION Saccharomyces boulardii CNCM I-745 is a good example for the statement that each probiotic needs to be taxonomically characterized and its efficacy and safety should be documented individually in different clinical settings.

Abstract
Increasing rates of antimicrobial resistance to clarithromycin and metronidazole present challenges in maintaining optimal eradication rates. Knowledge of local antibiotic resistance and consumption pattern is important in selecting a reliable regimen. In addition, adverse effect profiles of therapeutic regimens are important and must be addressed to enhance compliance rates. Various methods of enhancing the eradication rates of Helicobacter pylori (H. pylori) have been investigated, including changing combinations or durations of established drugs, adding adjuvant drugs, or development of new molecules or agents. Bismuth-containing quadruple, sequential, concomitant, and levofloxacin-based triple therapies are replacing the long-standing standard of the triple regimen. Despite the encouraging results of these regimens, individualized approaches like treatment after antibiotics resistance test or CYP2C19 genotyping would be the mainstream of future therapy. Because scientific, economic, and technical problems make these advance therapies unfit for widespread use, future development for H. pylori therapy should be directed to overcome individualized antibiotic resistance. Although various novel regimens and additive agents have indicated favorable outcomes, more studies or validations are needed to become a mainstream H. pylori therapy.

Meta-analysis of first-line triple therapy for helicobacter pylori eradication in Korea: is it time to change? J Korean Med Sci 2014; 29:704-13. [PMID: 24851029 PMCID: PMC4024949 DOI: 10.3346/jkms.2014.29.5.704] [Citation(s) in RCA: 63] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2013] [Accepted: 03/20/2014] [Indexed: 01/06/2023] Open
Abstract
Proton pump inhibitor (PPI)-based triple therapy consisting of PPI, amoxicillin, and clarithromycin, is the recommended first-line treatment for Helicobacter pylori infection. However, the eradication rate of triple therapy has declined over the past few decades. We analyzed the eradication rate and adverse events of triple therapy to evaluate current practices in Korea. A comprehensive literature search was performed up to August 2013 of 104 relevant studies comprising 42,124 patients. The overall eradication rate was 74.6% (95% confidence interval [CI], 72.1%-77.2%) by intention-to-treat analysis and 82.0% (95% CI, 80.8%-83.2%) by per-protocol analysis. The eradication rate decreased significantly from 1998 to 2013 (P < 0.001 for both intention-to-treat and per-protocol analyses). Adverse events were reported in 41 studies with 8,018 subjects with an overall incidence rate of 20.4% (95% CI, 19.6%-21.3%). The available data suggest that the effectiveness of standard triple therapy for H. pylori eradication has decreased to an unacceptable level. A novel therapeutic strategy is warranted to improve the effectiveness of first-line treatment for H. pylori infection in Korea.

Abstract
Helicobacter pylori is a major causative agent of gastritis and peptic ulcer disease and is an established risk factor for gastric malignancy. Antibiotic combination therapy can eradicate H. pylori. As these same regimens can evoke adverse effects and resistance, new alternative therapies or adjunctive treatments are needed. A probiotic approach may provide a novel strategy for H. pylori treatment. In the current study, two probiotic bacteria, Lactobacillus acidophilus and Lactobacillus reuteri, and a probiotic yeast, Saccharomyces boulardii, were evaluated for their ability to influence H. pylori viability, adherence to gastric and duodenal cells, as well as the effect of S. boulardii on cell surface expression of sialic acid. Our results indicate that S. boulardii contains neuraminidase activity selective for α(2-3)-linked sialic acid. This neuraminidase activity removes surface α(2-3)-linked sialic acid, the ligand for the sialic acid-binding H. pylori adhesin, which in turn, inhibits H. pylori adherence to duodenal epithelial cells.

Abstract
Cathelicidin, an antimicrobial peptide of the innate immune system, has been shown to modulate microbial growth, wound healing and inflammation. However, whether cathelicidin controls Helicobacter pylori infection in vivo remains unexplored. This study sought to elucidate the role of endogenous and exogenous mouse cathelicidin (CRAMP) in the protection against H. pylori infection and the associated gastritis in mice. Results showed that genetic ablation of CRAMP in mice significantly increased the susceptibility of H. pylori colonization and the associated gastritis as compared with the wild-type control. Furthermore, replenishment with exogenous CRAMP, delivered via a bioengineered CRAMP-secreting strain of Lactococcus lactis, reduced H. pylori density in the stomach as well as the associated inflammatory cell infiltration and cytokine production. Collectively, these findings indicate that cathelicidin protects against H. pylori infection and its associated gastritis in vivo. Our study also demonstrates the feasibility of using the transformed food-grade bacteria to deliver cathelicidin, which may have potential clinical applications in the treatment of H. pylori infection in humans.

Abstract
AIM: To investigate whether the addition of probiotics can improve the eradication effect of triple therapy for Helicobacter pylori (H. pylori) infection.
METHODS: This open randomized trial recruited 234 H. pylori positive gastritis patients from seven local centers. The patients were randomized to one-week standard triple therapy (omeprazole 20 mg bid, clarithromycin 500 mg bid, and amoxicillin 1000 mg bid; OCA group, n = 79); two weeks of pre-treatment with probiotics, containing 3 × 107Lactobacillus acidophilus per day, prior to one week of triple therapy (POCA group, n = 78); or one week of triple therapy followed by two weeks of the same probiotics (OCAP group, n = 77). Successful eradication was defined as a negative C13 or C14 urease breath test four weeks after triple therapy. Patients were asked to report associated symptoms at baseline and during follow-up, and side effects related to therapy were recorded. Data were analyzed by both intention-to-treat (ITT) and per-protocol (PP) methods.
RESULTS: PP analysis involved 228 patients, 78 in the OCA, 76 in the POCA and 74 in the OCAP group. Successful eradication was observed in 171 patients; by PP analysis, the eradication rates were significantly higher (P = 0.007 each) in the POCA (62/76; 81.6%, 95% CI 72.8%-90.4%) and OCAP (61/74; 82.4%, 95% CI 73.6%-91.2%) groups than in the OCA group (48/78; 61.5%, 95% CI 50.6%-72.4%). ITT analysis also showed that eradication rates were significantly higher in the POCA (62/78; 79.5%, 95% CI 70.4%-88.6%) and OCAP (61/77; 79.2%, 95% CI 70%-88.4%) groups than in the OCA group (48/79; 60.8%, 95% CI 49.9%-71.7%), (P = 0.014 and P = 0.015). The symptom relieving rates in the POCA, OCAP and OCA groups were 85.5%, 89.2% and 87.2%, respectively. Only one of the 228 patients experienced an adverse reaction.
CONCLUSION: Administration of probiotics before or after standard triple therapy may improve H. pylori eradication rates.

Abstract
Background To evaluate whether the addition of a probiotic could improve Helicobacter pylori (H.P.) eradication rates and reduce the side effects of treatment in children. Methods Between July 2008 and July 2011 all patients with a clinical, laboratory and endoscopic diagnosis of H.P. positive gastritis referred to our Unit were included in the study. Patients suffering from allergy to any of drugs used in the study, with previous attempts to eradicate H.P. and those who received antibiotics, PPIs or probiotics within 4 weeks were excluded from the present study. Patients were randomized into two therapy regimens (group A and B): both groups received standard triple treatment (omeprazole, amoxicillin and clarithromycin) while only group B patients were also given a probiotic (Probinul - Cadigroup). Patients compliance was evaluated at the end of the treatment. Successful eradication was defined as a negative 13 C-urea breath test (C13-ubt) result four weeks after therapy discontinuation. Results A total of 68 histopathologically proven H.P.-infection children (32 male and 36 females) were included in the study. All of the patients in both groups used more than 90% of the therapies and no patients were lost at follow up. All side effects were selflimiting and disappeared once the therapy was terminated. Epigastric pain was observed in 6 (17.6%) group A vs 2 (5.8%) group B patients (P<0.05), nausea in 3 (8.8%) group A vs 1 (2.9%) group B patients (P<0.05); vomiting and diarrhea were observed in 2(5.8%) and 8 (23.5%) group A patients, respectively and never in group B (P<0.05). There was no significant difference between the two groups in terms of constipation (5.8% in group A and B). Four weeks after the completion of therapy, 56/68 patients (82.3%) tested negative for H.P. on C13-ubt. H.P. was eradicated in 26 patients (76.4%) in group A and in 30 patients (88.2%) in group B. There was no significantly difference in the rate of H.P. eradication between group A and group B (p=0.1), although the success rate for H.P. eradication was higher in group B than in group A. Conclusion The addition of a probiotic formula to triple therapy significantly decreased the frequency of epigastric pain, nausea, vomiting and diarrhea.
