[PMID: 38928794 PMCID: PMC11202727 DOI: 10.3390/foods13121851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 05/21/2024] [Accepted: 05/29/2024] [Indexed: 06/28/2024] Open
Abstract
Probiotics are natural microbial agents with beneficial properties such as bacteriostatic and anti-infective properties. Lactobacillus plantarum Q21, Q25 and QA85, were isolated from the Chinese specialty fermented food "Jiangshui" and proved to be highly resistant to Helicobacter pylori (p < 0.0001). In vitro results showed that Q21, Q25 and QA85 strongly inhibited H. pylori and could specifically co-aggregate H. pylori in vitro (more than 56%). Strains have the potential to adhere to cells and hinder H. pylori colonization (p < 0.0001). To assess the anti-H. pylori efficacy of strains in vivo, volunteers were recruited and a self-controlled study of probiotic intervention was conducted. Compared to pre-probiotics, volunteers who took Q21, Q25 and QA85 for 1 month showed significant improvement in discomfort, a significant reduction in GSRS scores (p < 0.05), and modulation of inflammatory response (p < 0.05). Q21, Q25 and QA85 resulted in a decreasing trend of H. pylori load in volunteers (454.30 ± 327.00 vs. 328.35 ± 237.19, p = 0.06). However, the strains were not significantly effective in modulating the imbalance of the gut microbiota caused by H. pylori infection. In addition, strains affect metabolic pathways by increasing the levels of O-Phosphoethanolamine and other related metabolites, which may ameliorate associated symptoms. Therefore, Lactobacillus plantarum Q21, Q25 and QA85 can be regarded as a candidate probiotic preparation that exerts direct or indirect anti-H. pylori effects by inhibiting H. pylori activity and colonization, reducing inflammation and discomfort, maintaining homeostasis in the internal environment, affecting the metabolic pathways and repairing the body barrier. They can play a role in relieving H. pylori infection.

Nelwan EJ, Herdiman A, Kalaij AGI, Lauditta RK, Yusuf SM, Suarthana E. Role of probiotic as adjuvant in treating various infections: a systematic review and meta-analysis. BMC Infect Dis 2024; 24:505. [PMID: 38773400 PMCID: PMC11106949 DOI: 10.1186/s12879-024-09259-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Accepted: 03/26/2024] [Indexed: 05/23/2024] Open
Abstract
BACKGROUND Research on the advantages of probiotics has attracted increasing interest based on the number of publications, products, and public awareness of their benefits. This review evaluated the role of probiotics (single and multiple regimens) as an additional regimen to treat common infectious diseases, including Helicobacter. pylori, diarrheal infections, urinary tract infections (UTIs), upper respiratory tract infections (URTIs), and HIV infections. METHODS We searched randomized controlled trials from PubMed, Scopus, Embase, and Cochrane and identified 6,950 studies. Duplicates were removed, and titles and abstracts were filtered. Bias was evaluated using the Cochrane Risk of Bias Tool for Randomized Trials (ROB 1.0 and 2.0). The certainty of the evidence was evaluated using GRADE. Data were extracted and meta-analysis was performed using RevMan. RESULTS A total of 32 studies were included in this study (22 H. pylori studies, 2 diarrheal infection studies, 6 UTI studies, and 2 HIV infection studies). There was no study on URTI. Probiotics, in addition to primary treatment, could improve the eradication of H. pylori versus the control (RR: 1.09; 95% CI:1.04 - 1.13, p value = 0.001) and achieve a cure range of Nugent score in UTI patients (RR 1.38; 95% CI: 1.01 - 1.89, p value = 0.04). For eradicating H. pylori infection, subgroup analysis based on the therapy regimen showed that standard triple therapy was slightly superior compared to quadruple therapy in eradicating H. pylori (RR: 1.14 vs. 1.01, respectively). Single strain probiotics showed a similar effect to multiple strain probiotic regimens (both had an RR of 1.09). The effect estimates of the use of single strain probiotics as adjuvant therapy in eradicating H. pylori and the use of probiotics in UTI had a high certainty of evidence. Meta-analysis was not performed for infectious diarrheal because there were only two eligible studies with different probiotic supplementations and outcome parameters. Nonetheless, they showed that the diarrheal incidence was lower and complete remission of diarrheal was higher after the regimen of probiotics. Similarly, a meta-analysis was not performed for HIV infection because the two eligible studies used different designs and comparators with contradicting findings. CONCLUSION This meta-analysis showed beneficial use of single strain probiotics as adjuvant therapy in eradicating H. pylori and the use of probiotics in UTI. Probiotic supplementation might not be beneficial for patients given a quadruple therapy. Single-strain and multi-strain probiotic regimens had similar effects in increasing the eradication rate of H. pylori. Our study also suggested that the benefits of probiotics as an additional regimen in infectious diarrheal and HIV infections remain unclear; more studies are needed to confirm the benefits.

The modulatory effect of Lactobacillus gasseri ATCC 33323 on autophagy induced by extracellular vesicles of Helicobacter pylori in gastric epithelial cells in vitro. Microb Pathog 2024; 188:106559. [PMID: 38272328 DOI: 10.1016/j.micpath.2024.106559] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 01/22/2024] [Accepted: 01/22/2024] [Indexed: 01/27/2024]
Abstract
Helicobacter pylori has been recognized as a true pathogen, which is associated with various gastroduodenal diseases, and gastric adenocarcinoma. The crosstalk between H. pylori virulence factors and host autophagy remains challenging. H. pylori can produce extracellular vesicles (EVs) that contribute to gastric inflammation and malignancy. Some probiotic strains have been documented to modulate cell autophagy process. This study was aimed to investigate the modulatory effect of cell-free supernatant (CFS) obtained from Lactobacillus gasseri ATCC 33323 on autophagy induced by H. pylori-derived EVs. EVs were isolated from two clinical H. pylori strains (BY-1 and OC824), and characterized using transmission electron microscopy (TEM) and dynamic light scattering (DLS). The viability of AGS cells was assessed after exposure to different concentrations of H. pylori EVs, and L. gasseri CFS. Based on MTT assay and Annexin V-FITC/PI staining, 50 μg/ml of H. pylori EVs and 10 % v/v of L. gasseri CFS were used for further cell treatment experiments. Autophagy was examined using acridin orange (AO) staining, RT-qPCR analysis for autophagy mediators (LC3B, ATG5, ATG12, ATG16L1, BECN1, MTOR, and NOD1), and western blotting for LC3B expression. H. pylori EVs were detected to range in size from 50 to 200 nm. EVs of both H. pylori strains and L. gasseri CFS showed no significant effect on cell viability as compared to untreated cells. H. pylori EVs promoted the development of acidic vesicular organelles and the expression of autophagy-related genes (LC3B, ATG5, ATG12, ATG16L1, BECN1, and NOD1), and decreased the expression of MTOR in AGS cells at 12 and 24 h time periods. In addition, the production of LC3B was increased following 12 h of treatment in AGS cells. In contrast, L. gasseri CFS effectively inhibited EVs-induced autophagy, as evidenced by reduced acidic vesicular organelle formation and modulation of autophagy markers. Our study indicated that L. gasseri CFS can effectively suppress H. pylori EV-induced autophagy in AGS cells. Further investigations are required to decipher the mechanism of action L. gasseri CFS and its metabolites on autophagy inhibition induced by H. pylori.

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.

Abstract
The human gut is an intensively colonized organ containing microorganisms that can be health-promoting or pathogenic. This feature led to the development of functional foods aiming to fortify the former category at the expense of the latter. Since long, cultured products, including probiotics fortification, have been used for humans as live microbial feed additions. This review presents some of the microbes used as probiotics and discusses how supplementation with probiotics may help initiate and/or restore eubiotic composition of gut microbiota. Additionally, it considers safety and regulatory aspects of probiotics.

Koga Y. Microbiota in the stomach and application of probiotics to gastroduodenal diseases. World J Gastroenterol 2022; 28:6702-6715. [PMID: 36620346 PMCID: PMC9813937 DOI: 10.3748/wjg.v28.i47.6702] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 10/28/2022] [Accepted: 11/26/2022] [Indexed: 12/19/2022] Open
Abstract
The stomach is a hostile environment for most microbes because strong gastric acid kills indigenous microorganisms. Thus, the mass of indigenous microbes detected by traditional culturing method in a highly acidic stomach is reported to be very small. However, in a stomach with less acidity due to atrophic changes of the gastric mucosa, the number of live gastric microbiota dramatically increases and their composition changes. A probiotic is defined as a live microorganism that, when administered in adequate amounts, confers a health benefit on the host. The administration of probiotics to the stomach has thus far been considered impractical, mainly due to the strong acidity in the stomach. The identification of candidate probiotic strains with sufficient resistance to acidity and the ability to achieve close proximity to the gastric mucosa could enable the application of probiotics to the stomach. The utilization of probiotics alone for Helicobacter pylori (H. pylori) infection significantly improves gastric mucosal inflammation and decreases the density of H. pylori on the mucosa, although complete eradication of H. pylori has not yet been demonstrated. The use of probiotics in combination with antimicrobial agents significantly increases the H. pylori eradication rate, especially when the H. pylori strains are resistant to antimicrobial agents. While H. pylori has been considered the most important pathogenic bacterium for the development of gastric cancer, bacteria other than H. pylori are also suggested to be causative pathogens that promote the development of gastric cancer, even after the eradication of H. pylori. Increased non-H. pylori Gram-negative bacteria in the stomach with weak acidity accompanying atrophic gastritis may perpetuate gastric mucosal inflammation and accelerate carcinogenic progression, even after H. pylori eradication. Probiotics restore the acidity in this stomach environment and may therefore prevent the development of gastric cancer by termination of Gram-negative bacteria-induced inflammation. Functional dyspepsia (FD) is defined as the presence of symptoms that are thought to originate in the gastroduodenal region in the absence of any organic, systematic or metabolic diseases. Accumulating evidence has pointed out the duodenum as a target region underlying the pathophysiology of FD. A randomized placebo-controlled clinical trial using a probiotic strain (LG21) demonstrated a significant improving effect on major FD symptoms. One of the possible mechanisms of this effect is protection of the duodenal mucosa from injurious intestinal bacteria through the resolution of small intestinal bacterial over growth.

Abstract
Cancer is the second leading cause of elevated mortality worldwide. Thus, the development of drugs and treatments is needed to enhance the survival rate of the cancer-affected population. Recently, gut microbiota research in the healthy development of the human body has garnered widespread attention. Many reports indicate that changes in the gut microbiota are strongly associated with chronic inflammation-related diseases, including colitis, liver disease, and cancer within the intestine and the extraintestinal tract. Different gut bacteria are vital in the occurrence and development of tumors within the gut and extraintestinal tract. The human gut microbiome has significant implications for human physiology, including metabolism, nutrient absorption, and immune function. Moreover, diet and lifestyle habits are involved in the evolution of the human microbiome throughout the lifetime of the host and are involved in drug metabolism. Probiotics are a functional food with a protective role in cancer development in animal models. Probiotics alter the gut microbiota in the host; thus, beneficial bacterial activity is stimulated, and detrimental activity is inhibited. Clinical applications have revealed that some probiotic strains could reduce the occurrence of postoperative inflammation among cancer patients. An association network was constructed by analyzing the previous literature to explore the role of probiotics from the anti-tumor perspective. Therefore, it provides direction and insights for research on tumor treatment.

Abstract
In this study, we screened eight commercially available brands of Lactobacillus-containing probiotic preparations and dietary supplements for resistance towards commonly administered antibiotics of different classes. According to disc diffusion results, most of the isolates were resistant to vancomycin and susceptible to penicillin-type antibiotics (ampicillin and amoxicillin), carbapenems (imipenem, meropenem, and ertapenem), and inhibitors of protein synthesis (chloramphenicol, erythromycin, tetracycline, clarithromycin, and linezolid). However, based on minimum inhibitory concentration (MIC) values, six strains were reconsidered as resistant to tetracycline. All tested lactobacilli were resistant towards amikacin, ciprofloxacin, and norfloxacin. Resistance to cephalosporins was highly variable and decreased in the following order: ceftazidime/cefepime, ceftriaxone, cefotaxime, cefazolin, and cefoperazone. PCR screening for antibiotic resistance determinants in probiotic lactobacilli revealed a wide occurrence of vancomycin resistance gene vanX, ciprofloxacin resistance gene parC, and extended-spectrum β-lactamase gene blaTEM. We also detected the tetK gene for tetracycline resistance in one isolate. Additionally, we identified discrepancies between the claims of the manufacturers and the identified species composition, as well as the enumerated amount of viable bacteria, for several products. The results of this study raise concerns about the safety of lactobacilli for human consumption as probiotics, as they may act as reservoirs of transferable antibiotic resistance genes.

Abstract
Helicobacter pylori (H. pylori) infection is one of the most common in the world today, associated with the development of acute or chronic inflammatory diseases of the gastroduodenal tract. In order to eradicate the pathogen, various antibacterial therapy regimens have been proposed, based on the use of several chemotherapeutic drugs and a proton pump inhibitor (PPI). However, recent studies indicate a decrease in antibiotic effectiveness due to both the growth rate of H. pylori resistance and side effects, often due to the development of dysbiosis. One of the promising areas of investigation is the treatment with probiotic therapy of helicobacteriosis. The use of probiotics, in the context of H. pylori infection, has two main reasons. The first is related to the use of certain probiotics to reduce the frequency of undesirable gastrointestinal consequences during H. pylori eradication therapy. The second is associated with the antagonistic effect of individual probiotics on H. pylori and the potentiation of the eradication effect. The purpose of this review was to summarize the latest data on the use of probiotics to enhance H. pylori eradication and to restore the gastrointestinal microbiota. Many unresolved questions, about the choice of the specific composition of the probiotic cocktail, dosage, duration of therapy, mechanisms of the antimicrobial action of probiotics, as well as possible negative consequences of such therapy, remain.

Abstract
In recent times, the status of some fermented foods which are considered as functional foods that confer health benefits in certain disease conditions has grown rapidly. The health benefits of fermented foods are due to the presence of probiotic microbes and the bioactive compound formed during fermentation. Microbes involved and metabolites produced by them are highly species-specific and contribute to the authenticity of the fermented foods. Several studies pertaining to the effect of fermented foods on various disease conditions have been conducted in recent years using both animal models and clinical trials on humans. This review focuses on the impact of fermented foods on conditions like diabetes, cardiovascular disease (CVD), obesity, gastrointestinal disorder, cancer and neurodegenerative disorders.

Abstract
Gastritis is the acute or chronic inflammation of gastric mucosa and is triggered by diverse factors. Treatments used for non-bacterial gastritis include proton pump inhibitors, histamine H2 receptor inhibitors, and antacids, and their use is linked to various side effects. Research on alternative therapeutics using food or food-based products is extensive, mostly in preclinical research. We aimed at documenting the clinical advances in food-based therapies as alternative therapeutics for gastritis. Articles with information on the treatment of gastritis with food or food-based products published until December 1, 2020 were identified through a systematic search in PubMed Medline Database. Additionally, references of retrieved articles were screened for relevant reviews and meta-analyses. Two investigators independently selected and reviewed the titles and abstracts of articles and extracted the study characteristics (PICO framework) and key findings. Dual quality assessment and data extraction were performed. We found 28 clinical studies evaluating garlic, turmeric, red peppers, broccoli sprouts, cranberry juice, honey, oils, and probiotics contained in different foods, such as juices, yogurt, and cheese. The existing literature presents a high risk of bias, and results of the same should be evaluated and replicated with precaution; more rigorous clinical studies are lacking.

Abstract
Helicobacter pylori is a Gram-negative microorganism that causes chronic dyspepsia, gastritis, mucosa-associated lymphoid tissue (MALT) lymphoma, and gastric adenocarcinoma. Various antibiotic regimens are employed to eradicate it; however, antibiotic resistance has skyrocketed in recent years, resulting in a reduction in eradication rates. As a result, numerous novel therapeutic approaches are being adopted in clinical practice, and probiotics are being extensively investigated. Probiotics are living bacteria that, when consumed, offer many medicinal advantages that may be accomplished by altering the amount or activity of gut flora. Their beneficial influence on gut health, immune system modulation, and cancer therapy is the subject of extensive investigation. This is owing to their perceived safety and simplicity of use. The primary objective of this review is to learn about and investigate the function of probiotics in the eradication of H. pylori, either alone or in conjunction with traditional treatments. Data have been collected from PubMed, PubMed Central, Medline, Cochrane, and Google Scholar, and relevant articles have been chosen following the PRISMA guidelines. Our search resulted in 2489 records, of which 123 full-text articles were screened for eligibility. Two reviewers independently performed the quality appraisal of 16 relevant articles, and ultimately 11 high-quality studies are included in this review. In conclusion, probiotic monotherapy does not have a significant effect on the eradication rates of H. pylori, but in conjunction with standard treatment regimens, there was mild improvement in the eradication rates but a significant reduction of side effects due to antibiotics.

Abstract
Helicobacter pylori is a highly prevalent human-specific pathogen that causes various gastric diseases. In the present study, Lactobacillus plantarum ZJ316, which could survive well in simulated gastrointestinal conditions, was found to have significant anti-H. pylori ability. Animal assays revealed that L. plantarum ZJ316 had preventive and therapeutic effects on H. pylori-induced gastritis. L. plantarum ZJ316 significantly decreased interferon γ (IFN-γ) and interleukin 6 (IL-6) levels, increased the IL-10 level, and repaired mucosal damage. Moreover, 16S rRNA gene sequencing revealed that the relative abundance of H. pylori could be significantly reduced by L. plantarum ZJ316 administration. Members of the families Dehalobacteriaceae and Geodermatophilaceae were more prevalent in the prevention group, while Lactobacillaceae and Actinomycetaceae were more prevalent in the treatment group. These results indicate that L. plantarum ZJ316 serves as a potential candidate for the prevention and treatment of H. pylori-induced gastritis by regulating the gastric microbiota and reducing mucosal inflammation.

The Effect of Continuous Intake of Lactobacillus gasseri OLL2716 on Mild to Moderate Delayed Gastric Emptying: A Randomized Controlled Study. Nutrients 2021; 13:nu13061852. [PMID: 34071718 PMCID: PMC8230235 DOI: 10.3390/nu13061852] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2021] [Revised: 05/25/2021] [Accepted: 05/27/2021] [Indexed: 11/17/2022] Open
Abstract
Probiotics have been suggested to be effective for functional dyspepsia, but their effect on gastric motility is not clear. We evaluated the effect of Lactobacillus gasseri OLL2716 (LG21 strain) on mild to moderate delayed gastric emptying by a double-blind, parallel-group, placebo-controlled, randomized trial. Participants (n = 28) were randomly assigned to ingest LG21 strain-containing yogurt (LG21 strain group) or LG21 strain-free yogurt (placebo group) for 12 weeks. The 13C gastric emptying breath test was performed to measure the gastric emptying rate over time following ingestion of a liquid meal, and the time to reach the peak (Tmax) was used as an indicator of gastric emptying. We also measured the salivary amylase concentration, an indicator of autonomic dysfunction under stress. The per-protocol population (n = 27, male n = 4, female n = 23) was evaluated for efficacy. When a ≥30% reduction in the difference between participant's Tmax and the Japanese mean Tmax was defined as an improvement, the odds ratio of improvement in delayed gastric emptying compared to placebo after 12 weeks was 4.1 (95% confidence interval, 0.8 to 20.2). Moreover, salivary amylase concentrations were significantly lower than in the placebo group, indicating an improvement in autonomic function. The present data were not enough to support the beneficial effects of the LG21 strain on delayed gastric emptying. However, if we define the odds ratio in further study investigated with a larger number of participants, LG21 strain might be expected to have some impact on delayed gastric emptying.

Effects of a Potential Probiotic Strain Lactobacillus gasseri ATCC 33323 on Helicobacter pylori-Induced Inflammatory Response and Gene Expression in Coinfected Gastric Epithelial Cells. Probiotics Antimicrob Proteins 2020; 13:751-764.

Abstract
In the present study, we aimed to investigate the modulatory effects of a potential probiotic bacterium Lactobacillus gasseri ATCC 33323 on Helicobacter pylori-induced inflammatory response and gene expression in human gastric adenocarcinoma (AGS) cell line. The gastric epithelial cells were coinfected with a collection of H. pylori clinical strains alone or in combination with L. gasseri at a multiplicity of infection (MOI) of 1:100 for each bacterium, and incubated for different time points of 3, 6, and 12 h. IL-8 secretion from coinfected AGS cells after incubation at each time point was measured by an enzyme-linked immunosorbent assay (ELISA). The mRNA expression of IL-8, Bcl-2, β-catenin, integrin α5, and integrin β1 genes was determined by quantitative RT-PCR amplification of total RNA extracted from coinfected epithelial cells. L. gasseri significantly (P < 0.05 and P < 0.01) decreased the production of IL-8 in AGS cells coinfected with H. pylori strains at 6 h post-infection. We also detected that L. gasseri significantly (P < 0.05) down-regulated the gene expression level of IL-8 in H. pylori-stimulated AGS cells after 6 and 12 h of coinfection. Similarly, L. gasseri caused a significant decrease (P < 0.05) in mRNA expression of Bcl-2, β-catenin, integrin α5, and integrin β1 genes in AGS cells at 3 and 6 h after infection with H. pylori strains as compared with non-infected control cells. In conclusion, our results demonstrated that L. gasseri ameliorates H. pylori-induced inflammation and could be developed as a supplementation to the current treatment regimens administrated against H. pylori infection.

Abstract
Traditional therapies for Helicobacter pylori (H. pylori) infection remain hindered by the antibiotic resistance of the pathogen and the poor therapeutic compliance of patients. To address these issues, probiotics have been added as an adjunctive therapy. This meta-analysis aimed to evaluate the efficacy of probiotic supplementation during standard therapy on the eradication rate of H. pylori infection and incidence of therapy-related side effects. Four online databases were searched for eligible studies without language restriction. Review Manager (REVMAN, Version 5.3) was used to perform all data analyses. Forty articles including 5792 patients met our criteria and were included in the analysis. Notably, probiotic supplementation improved the eradication rate by approximately 10% relative to the control group [odds ratio (OR), 1.94, 95% confidence interval (CI): 1.70-2.22, P < 0.00001]. The incidence of total side effects (OR, 0.56, 95% CI: 0.45-0.70, P < 0.00001) and individual symptoms (e.g., diarrhea, vomiting and nausea, constipation, epigastric pain, taste disturbance) also decreased significantly with probiotic supplementation. No other differences in side effects were observed between the experimental and control groups. Moreover, a longer duration (≥10 days) of probiotic treatment had positive effects on both eradication rate of H. pylori and incidence of overall side effects.

Abstract
Helicobacter pylori is a well-known pathogen that is highly prevalent in the world population, and H. pylori infection is potentially hazardous to humans because of its relationship to various gastrointestinal diseases, such as gastric ulcers, chronic gastritis, and gastric carcinoma. Therefore, the clinical guidelines recommend taking antibiotic therapy to eradicate the pathogen, which usually leads to the desired therapeutic effect. However, some failure cases of this therapy indicate that the increasing antibiotic resistance and side effects may affect the therapeutic effect. Here we propose that using probiotics as supplementation for antibiotic therapy may provide an extra help. Recent studies have shown that probiotic supplementation therapy has promising application prospects; it can enhance the antibiotic effect to achieve a better therapeutic result and maintain the balance of the host gastrointestinal microbiota. In summary, under global conditions of increasing H. pylori prevalence, probiotic supplementation therapy is worthy of further studies for future clinical application.

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

Abstract
Objective To describe probiotics including a Lactobacillus gasseri strain LG21 used for the upper gastrointestinal tract, which are considered to act through improvement of indigenous microbiota inhabiting there. Background and design Because the early definition of probiotics emphasized their effects on improving the intestinal microbial ecology, their effects on the intestinal tract and its immunity have been considered common general benefits associated with probiotics. This conclusion was also based on a body of successful clinical trials whose endpoints were the prevention or treatment of intestinal diseases. In contrast to intestinal microbiota, our understanding of the role of gastric microbiota in human health and physiology remains poor, as the bacterial load in the stomach is considered too small to exert a significant effect due to the highly acidic environment of the human stomach. Therefore, the intervention using probiotics in the stomach is still limited at present.Results:In this article using representative 38 quoted articles, we first describe the gastric microbiota, as the indigenous microbiota in the stomach is thought to be significantly involved in the pathophysiology of this organ, since probiotics exert their beneficial effects through improving the resident microbiota. We then review the present status and future prospects of probiotics for the treatment of upper gastrointestinal diseases by quoting representative published articles, including our basic and clinical data. Conclusions Probiotics have been demonstrated to suppress Helicobacter pylori in the stomach, and are also expected to improve functional dyspepsia through the correction of dysbiotic gastric microbiota.

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.

Abstract
AIM To evaluate the efficacy and safety of Bifidobacterium combined with ilaprazole-containning quadruple therapy in rescue eradication of Helicobacter pylori (H. pylori).
METHODS Two hundred and eighty H. pylori infected patients who failed initial treatment were randomly divided into four groups: A-D. Group A was treated with ilaprazole, amoxicillin, furazolidone, and colloidal bismuth pectin for 14 d. Group B was simultaneously given Bifidobacterium for 14 d on the basis of the therapy in group A. Groups C and D were, respectively, given Bifidobacterium for 28 d before the same therapy in groups A and B. H. pylori eradication was assessed by C13-urea breath test (C13-UBT), and the incidence of adverse reactions was compared in the four groups at 4 wk after treatment.
RESULTS In total, 251 patients completed the treatment and follow-up according to the experimental design. Intention-to-treat (ITT) analysis showed that the H. pylori eradication rates in groups A, B, C, and D were 62.85, 71.43, 75.71, and 77.14, respectively, and per-protocol (PP) analysis showed that the eradication rates in groups A, B, C, and D were 72.13, 79.36, 84.13, and 84.38, respectively. The eradication rates in groups B, C, and D were significantly higher than that in group A (P < 0.05), and the eradication rates in groups C and D were significantly higher than that in group B (P < 0.05), while no statistically significant difference was found between groups C and D (P > 0.05). The completion rates in groups A, B, C, and D were 87.14 (61/70), 90.00 (63/70), 90.00 (63/70), and 91.43 (64/70), respectively. The completion rates in groups B, C, and D were significantly higher than that in group A (P < 0.05), while there was no significant difference in the completion rates among group B, C, and D (P > 0.05). The incidence of adverse reactions in groups A, B, C, and D was 14.92, 10.61, 7.46, and 6.06, respectively. The incidence of adverse reactions in groups B, C, and D was significantly lower than that in group A (P < 0.05), and the incidence of adverse reactions in groups C and D was significantly lower than that in group B (P < 0.05), while there was no significant difference in the incidence of adverse reactions between groups C and D (P > 0.05).
CONCLUSION Bifidobacterium can effectively improve the rescue eradication rates of H. pylori, decrease the incidence of adverse reactions, and improve the compliance with treatment.

Abstract
Helicobacter pylori drug resistance presents a significant challenge to the successful eradication of this pathogen. To find strategies to improve the eradication efficacy of H. pylori, it is necessary to clarify the resistance mechanisms involved. The mechanisms of H. pylori drug resistance can be investigated from two angles: the pathogen and the host. A comprehensive understanding of the molecular mechanisms of H. pylori resistance based on both pathogen and host would aid the implementation of precise therapy, or ideally "dual target precise therapy" (bacteria and host-specific target therapy). In recent years, with increased understanding of the mechanisms of H. pylori resistance, the focus of eradication has shifted from disease-specific to patient-specific treatment. The implementation of "precision medicine" has also provided a new perspective on the treatment of infectious diseases. In this article, we systematically review current research on H. pylori drug resistance from the perspective of both the pathogen and the host. We also review therapeutic strategies targeted to pathogen and host factors that are aimed at achieving precise treatment of H. pylori.

Abstract
Helicobacter pylori is involved in the pathogenesis of gastritis, peptic ulcer, and gastric cancer. The infection is prevalent in more than half of the world's population. Although the infection may lead to detrimental consequences, still the majority of the infected individuals only develop mild gastritis. Several factors are behind this paradoxical outcome including virulence of the infecting H. pylori strains, genetic background of the host, and factors related to lifestyle such as dietary habits. Among these, lifestyle including dietary factors was not in the limelight, until recently, as one of the important factors that could modulate H. pylori-linked gastric diseases. This review is directed to gather and elucidate the role of dietary components in augmenting or attenuating pathological processes initiated by H. pylori. Available evidence strongly supports the notion that the diet may play a critical role in defining the final outcome of H. pylori infection particularly if certain dietary components are taken on a regular basis for a long time. Despite a recent surge in research related to the role of dietary ingredients, further studies involving large-scale clinical trials are required to gain a better understanding of the precise role played by the dietary ingredients in H. pylori-associated pathogenesis.

Abstract
OBJECTIVE The aims of the study were: 1, to survey the most popular anti-H. pylori regimens in Asia-Pacific region and the real-world effectiveness of these regimens; and 2, to investigate the expectation gaps of eradication rate between physicians and patients. DESIGN A questionnaire was distributed to Asia-Pacific physicians who attended the Asia-Pacific Digestive Week 2015 meeting. Reported eradication rates from the literatures were compared with real-world rates of surveyed popular regimens within the region. In addition, a questionnaire was distributed to H. pylori-infected patients in three regions of Taiwan. RESULTS A total of 691 physicians and 539 patients participated in the survey. The top five most commonly used regimens were 7-day clarithromycin-based standard triple therapy (50.4%), 14-day clarithromycin-based standard triple therapy (31.0%), 10-day sequential therapy (6.1%), 14-day bismuth quadruple therapy (3.9%), and 14-day hybrid therapy (3.6%). All countries except for China had a significant gap between the expectation of physicians on anti-H. pylori therapy and the real-world eradication rate of most commonly adopted regimens (all P value <.05). The expectation on minimal eradication rate among patients was higher than that of physicians (91.4% vs 86.5%, P<.001). CONCLUSIONS It is time for physicians in Asia-Pacific countries to adopt newer and more efficacious anti-H. pylori regimens to meet the Kyoto consensus recommendation and their patients' expectations.

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
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 AND AIM We assessed whether adherent gastric mucous to biopsy forceps instead of biopsy samples was suitable for the diagnosis of H. pylori infection. We confirmed the PCR methods to improve the diagnosis of H. pylori infection and clarithromycin (CAM) susceptibility. METHODS Gastric mucous was obtained by gently scraping gastric mucosa using biopsy forceps in patients undergoing upper gastrointestinal (GI) endoscopy for PCR and rapid urease test (RUT). DNA was extracted from gastric mucous present within the gel of RUT. H. pylori status and CAM susceptibility were evaluated using H. pylori-specific PCR amplification for 23S rRNA using 4 different primer sets and 16S rRNA. H. pylori positive was defined as two of the three tests (serum antibody, histology, and RUT or PCR) were positive. CAM susceptibility was evaluated by point mutations (A 2142G and A 2143G of 23S rRNA). RESULTS Samples taken from 494 subjects were evaluated: 300 H. pylori-positive patients and 194 negative patients. The results of PCR using DNA extracted from gastric mucous present within the RUT gel were consistent with those within water. The accuracy of 23S rRNA PCR for H. pylori detection using RUT samples was superior to the other tests. The frequency of CAM resistance was 38.9%, and eradication rate was 91.3% in the patients with wild-type and 47.0% in the patients with the mutant strains. CONCLUSION Adherent gastric mucous to biopsy forceps in RUT gel can be used for molecular testing to confirm the diagnosis of H. pylori infection and for CAM susceptibility.

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

Abstract
More than a million people die every year due to gastric cancer and peptic ulcer. Helicobacter pylori infection in stomach is the most important reason for these diseases. Interestingly, only 10-20% of the H. pylori infected individuals suffer from these gastric diseases and rest of the infected individuals remain asymptomatic. The genotypes of H. pylori, host genetic background, lifestyle including smoking and diet may determine clinical outcomes. People from different geographical regions have different food habits, which also include several unique fermented products of plant and animal origins. When consumed raw, the fermented foods bring in fresh inocula of microbes to gastrointestinal tract and several strains of these microbes, like Lactobacillus and Saccharomyces are known probiotics. In vitro and in vivo experiments as well as clinical trials suggest that several probiotics have anti-H. pylori effects. Here we discuss the possibility of using natural probiotics present in traditional fermented food and beverages to obtain protection against H. pylori induced gastric diseases.

Abstract
Some Lactobacillus spp. suppress Helicobacter pylori in the stomach and have potential therapeutic applications for the treatment of gastrointestinal conditions. In this study, the effects of Lactobacillus strains on functional dyspepsia associated with H. pylori infection were examined. Volunteers were screened using the 13C-urea breath test (UBT) and H. pylori stool test, and 131 participants who met the selection criteria (mean age: 48.9 years) were randomly given L. gasseri OLL2716-containing yogurt or placebo yogurt once daily for 12 weeks. Gastrointestinal symptoms (epigastric pain, bloating, postprandial fullness, nausea, and heartburn) and the levels of serum pepsinogen (PG), 13C-UBT, and H. pylori stool antigen were assessed. No significant differences were observed between the groups in UBT results, H. pylori stool antigens, or the serum PGI/II ratio. In the L. gasseri group, postprandial fullness was significantly lower at the end of the trial compared to the initial level (p < 0.05) and significantly fewer patients had a VAS score of >10 for bloating compared to the placebo group (p < 0.05). Dietary supplementation with L. gasseri OLL2716-containing yogurt may effectively suppress dyspeptic symptoms in H. pylori-infected patients. This study was registered at the University Hospital Medical Network Clinical Trial Registry (UMIN000016746).

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
The gut microbiome is not a silent ecosystem but exerts several physiological and immunological functions. For many decades, lactobacilli have been used as an effective therapy for treatment of several pathological conditions displaying an overall positive safety profile. This review summarises the mechanisms and clinical evidence supporting therapeutic efficacy of lactobacilli. We searched Pubmed/Medline using the keyword ‘Lactobacillus’. Selected papers from 1950 to 2015 were chosen on the basis of their content. Relevant clinical and experimental articles using lactobacilli as therapeutic agents have been included. Applications of lactobacilli include kidney support for renal insufficiency, pancreas health, management of metabolic imbalance, and cancer treatment and prevention. In vitro and in vivo investigations have shown that prolonged lactobacilli administration induces qualitative and quantitative modifications in the human gastrointestinal microbial ecosystem with encouraging perspectives in counteracting pathology-associated physiological and immunological changes. Few studies have highlighted the risk of translocation with subsequent sepsis and bacteraemia following probiotic administration but there is still a lack of investigations on the dose effect of these compounds. Great care is thus required in the choice of the proper Lactobacillus species, their genetic stability and the translocation risk, mainly related to inflammatory disease-induced gut mucosa enhanced permeability. Finally, we need to determine the adequate amount of bacteria to be delivered in order to achieve the best clinical efficacy decreasing the risk of side effects.

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
Treatment of Helicobacter pylori infection is becoming increasingly challenging due largely to the rising rates of antimicrobial resistance and to the relative complexity of treatment regimens. If a reliable test to assess the antimicrobial sensitivity/resistance of H. pylori was readily available, treatment would be more focused and-presumably-more effective. However, antimicrobial sensitivity testing is difficult to obtain in most parts of the United States. Therefore, physicians have to rely on clinical judgment in selecting treatment regimens for their infected patients. The aims of this review are to summarize recent treatment recommendations and to examine available evidence for how we might improve on our current treatment selections. Information on this review is directed primarily toward physicians practicing in the United States.

Abstract
Helicobacter pylori (H. pylori) causes many diseases, including peptic ulcer, chronic gastritis, gastric cancer and mucosal-associated lymphoid tissue lymphoma (MALT lymphoma). In recent years, the eradication rate of H. pylori using traditional triple therapy has declined year by year. In order to improve the eradication rate of H. pylori, some scholars put forward the theory of "fighting bacteria with bacteria". This paper reviews the status of probiotic usage for improvement of H. pylori eradication in China.

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

Abstract
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.

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
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.

Abstract
BACKGROUND The standard triple therapy for the eradication of Helicobacter pylori consists of a combination of a proton pump inhibitor at a standard dose together with two antibiotics (amoxicillin 1000 mg plus either clarithromycin 500 mg or metronidazole 400 mg) all given twice daily for a period of 7-14 days. Recent reports have shown a dramatic decline in the rate of H. pylori eradication utilizing standard triple therapy from 95% down to 70-80%. AIMS Our study was designed to evaluate the effect of adding a probiotic as an adjuvant to common regimens used for H. pylori eradication. MATERIALS AND METHODS An open label randomized observational clinical study was designed to test three different regimens of H. pylori eradication treatment: Standard triple therapy with a concomitant probiotic added at the same time (n = 100), starting the probiotic for 2 weeks before initiating standard triple therapy along with the probiotic (n = 95), and the third regimen consists of the probiotic given concomitantly to sequential treatment (n = 76). The three arms were compared to a control group of patients treated with the traditional standard triple therapy (n = 106). RESULTS The eradication rate for the traditional standard therapy was 68.9%, and adding the probiotic "Bifidus infantis" to triple therapy, led to a successful rate of eradication of 83% (P < 0.001). Pre-treatment with 2 weeks of B. infantis before adding it to standard triple therapy increased the success rate of eradication to 90.5%. Similar improvement in eradication rate was noted when B. infantis was added as an adjuvant to the sequential therapy leading to an eradication rate of 90.8%. CONCLUSION Adding B. infantis as an adjuvant to several therapeutic regimens commonly used for the eradication of H. pylori infection significantly improves the cure rates.
