Helicobacter pylori (Hp) eradication therapy alters gut microbiota, provoking gastrointestinal (GI) symptoms that could be improved by probiotics. The study aim was to assess the effect in Hp patients of a Test fermented milk containing yogurt and Lacticaseibacillus (L. paracasei CNCM I-1518 and I-3689, L. rhamnosus CNCM I-3690) strains on antibiotic associated diarrhea (AAD) (primary aim), GI-symptoms, gut microbiota, and metabolites. A randomised, double-blind, controlled trial was performed on 136 adults under 14-day Hp treatment, receiving the Test or Control product for 28 days. AAD and GI-symptoms were reported and feces analysed for relative and quantitative gut microbiome composition, short chain fatty acids (SCFA), and calprotectin concentrations, and viability of ingested strains. No effect of Test product was observed on AAD or GI-symptoms. Hp treatment induced a significant alteration in bacterial and fungal composition, a decrease of bacterial count and alpha-diversity, an increase of Candida and calprotectin, and a decrease of SCFA concentrations. Following Hp treatment, in the Test as compared to Control group, intra-subject beta-diversity distance from baseline was lower (padj = 0.02), some Enterobacteriaceae, including Escherichia-Shigella (padj = 0.0082) and Klebsiella (padj = 0.013), were less abundant, and concentrations of major SCFA (p = 0.035) and valerate (p = 0.045) were higher. Viable Lacticaseibacillus strains were detected during product consumption in feces. Results suggest that, in patients under Hp treatment, the consumption of a multi-strain fermented milk can induce a modest but significant faster recovery of the microbiota composition (beta-diversity) and of SCFA production and limit the increase of potentially pathogenic bacteria.

AbstractBACKGROUNDHelicobacter pylori (Hp) eradication therapy can alter gut microbiota, provoking gastro-intestinal (GI) symptoms that can be improved by probiotics. The effect on Hp patients of a Test fermented milk containing yogurt and three Lacticaseibacillus (L. paracasei CNCM I-1518, CNCM I-3689, L. rhamnosus CNCM I-3690) strains was assessed on antibiotic associated diarrhea (AAD) (primary aim), GI-symptoms, gut microbiota composition and metabolites. In this aim, a randomized, double-blind, controlled trial was performed in 136 adults under Hp-treatment (14-day amoxicillin, clarithromycin, pantoprazole), who consumed the Test or a Control product for 28 days. Feces were analysed for gut microbiota composition, short chain fatty acids (SCFA), calprotectin, and viability of ingested strains.RESULTSNo effect of Test product was observed on AAD occurrence or duration, rating scores or number of days of GI symptoms. Hp-treatment induced a significant alteration in bacterial and fungal composition, a decrease of bacterial count and alpha-diversity, an increase of Candida and of calprotectin, and a decrease of SCFA concentration. Following Hp treatment, in the Test as compared to Control group, intra-subject beta-diversity distance from baseline was lower (padj=0.02), Escherichia-Shigella (padj=0.0082) and Klebsiella (padj= 0.013) were significantly less abundant, and concentrations of major SCFA (p=0.035) and valerate (p = 0.045) were higher. Viable Lp and Lr strains from the Test product were mainly detected during product consumption in feces.CONCLUSIONSThe study showed that 14-day Hp triple therapy alters gut bacterial and fungal community, their metabolites and gut inflammatory markers. Consumption of a multi-strain fermented milk can induce faster recovery of the microbiota composition and SCFA production and limit the bloom of pathobionts.

Background Helicobacter pylori (H. pylori) infection is thought to be the etiology of chronic gastritis, peptic ulcer, and risk factor for gastric cancer. Management of H. pylori infection in children is associated with several problems such as compliance to therapy, untolerated side effects, and antibiotic resistance. Probiotic is reported to give beneficial effect in the management of H. pylori infection and there is no study yet on the effect of probiotic in eradication of H. pylori infection in Indonesian children.Objectives To study the effect of additional probiotic in the standard therapy on the rate of H. pylori infection eradication in children and its side effect.Methods This was a double blind randomized controlled trial performed in 23 children with H. pylori infection at Kampung Melayu and Rawa Bunga District. The diagnosis was determined based on Helicobacter pylori stool antigen test (HpSA). Subjects were randomly assigned to either receive receive amoxiycilin, clarithromycin, omeprazole, and probiotic (2 x 109 cfu of Lactobacillus acidophilus La5 and Bifidobacterium lactis Bb12) or amoxicillin, clarithromycin, omeprazole dan placebo (maltodextrin). HpSA examination was evaluated again after 2 weeks of therapy.Results Two of 13 subjects in the treatment group and 6 of 10 subjects in the control group experienced side effects. Eradication rate in the treatment group is higher than the control group (13/13 vs 7/10) but the correlation between additional probiotic with the eradication rate of H. pylori is not statistically significant.Conclusions Probiotic can reduce the incidence of side effects due to antibiotic used in H. pylori eradication (2/13 vs 6/10, p < 0.012).

Abstract Background: Whether the screening and treatment of Helicobacter pylori infection are safe for children is debated in Japan. This study aimed to evaluate the safety of Helicobacter pylori eradication therapy by examining long-term changes in the gut microbiota during therapy among children.Methods: Children with anti-Helicobacter pylori antibody in the urine and Helicobacter pylori antigen in the feces were enrolled in this study. Their stool samples were collected at three time points, which were as follows: prior to treatment, 1–2 days after treatment, and time of judgment of eradication therapy. After treatment, the relative abundance, alpha-diversity, and beta-diversity of the gut microbiota were assessed.Results: In 16 students finally included in the study, the number of Actinobacteria isolated decreased immediately after eradication therapy, and it returned to pretreatment condition at the judgment point. There was no change at the genus level. The alpha-diversity was lost immediately after eradication therapy. However, it recovered at the time of eradication judgment, and it was restored before eradication therapy. Meanwhile, there was no change in beta-diversity, and none of the participants experienced serious adverse events.Conclusion: Helicobacter pylori eradication therapy is safe even for children in the view point of gut microbiota. Thus, further long-term evaluations of changes in the gut microbiota after eradication therapy and an assessment of healthy children without Helicobacter pylori must be performed. These will in turn promote screening and treatment among adolescents to prevent gastric cancer.Trial registration: This study was registered with the University Hospital Medical Information Network Clinical Trials Registry (no. UMIN000028726, https://upload.umin.ac.jp/cgi-bin/ctr_e/ctr_view.cgi?recptno=R000032873) on 18 August 2017.

Abstract Background The low intake of dietary fiber compared to recommended amounts has been referred to as the dietary fiber gap. The addition of fiber to snack foods could favorably alter gut microbiota and help individuals meet intake recommendations. Objectives Our objective was to examine the effect of low- and moderate-dose fiber-containing snack bars, comprising mainly chicory root inulin-type fructans (ITF), on gut microbiota in healthy adults with habitual low dietary fiber intake using 16S ribosomal RNA–based approaches. Methods In 2 separate 4-wk, placebo-controlled, double-blind, crossover trials, 50 healthy adults with low dietary fiber intake were randomly assigned to receive isocaloric snack bars of either moderate-dose fiber (7 g/d) or control in Trial 1 (n = 25) or low-dose fiber (3 g/d) or control in Trial 2 (n = 25), with 4-wk washout periods. Fecal microbiota composition and inferred function, fecal SCFA concentration, gastrointestinal (GI) symptoms, dietary intake, and quality of life were measured. Results Compared with the control group, the moderate-dose group showed significant differences across multiple microbial taxa, most notably an increased relative abundance of the Bifidobacterium genus from (mean ± SEM) 5.3% ± 5.9% to 18.7% ± 15.0%. With low-dose ITF, significant increases in Bifidobacterium were no longer present after correction for multiple comparisons but targeted analysis with qPCR showed a significant increase in Bifidobacterium. Predictive functional profiling identified changes in predicted function after intake of the moderate- but not the low-dose bar. Fecal SCFAs were affected by time but not treatment. There were no between-group differences in GI symptoms. Importantly, fiber intake increased significantly with the moderate- and low-dose bars. Conclusions In healthy adults, adding 3 or 7 g ITF to snack bars increased Bifidobacterium, a beneficial member of the gut microbial community. The addition of ITF to food products could help reduce the dietary fiber gap prevalent in modern life. This trial was registered at clinicaltrials.gov as NCT03042494.

Abstract Background: The primary goal of this placebo-controlled study was to determine the effect of quadruple treatment with Saccharomyces boulardii or Lactobacillus reuteri on the eradication of Helicobacter pylori and side effects of the treatment.Results: This study was a double-blind, randomized, placebo-controlled trial. And, eradication of helicobacter pylori was reported comparing conventional anti-H. Pylori therapy versus conventional therapy supplemented with S. boulardii and L. reuteri DSMZ 17648. For this aim, a total of 156 patients were included in the current study; and patients positive for H. Pylori infection (n =156) were randomly assigned to 3 groups: 52 patients (Group P) received conventional quadruple therapy plus L. reuteri, 52 patients (Group S) received conventional quadruple therapy plus S. boulardii daily, for 2 weeks, and 52 patients were in the control group (Group C). At the end of the treatment period, all the subjects continued to take proton pump inhibitor (PPI) alone for 14 days, and then, no medication was given for 2 weeks again. During follow-up, gastrointestinal symptoms were assessed using an evaluation scale (Glasgow dyspepsia questionnaire (GDQ)), and adverse events were assessed at 7, 14, 21, and 28 days. As a result, eradication therapy was effective for 94.2% of subjects in Group S, 92.3% of subjects in Group P, and 86.5% of subjects in the control group, with no differences between treatment arms. In Group S, the chance of developing symptoms of nausea (OR=2.74), diarrhea (OR=3.01), headache (OR=10.51), abdominal pain (OR=3.21), and anxiety (OR=3.58) was significantly lower than in the control group (p<0.05).Conclusion: In general, our findings revealed that the use of probiotic supplements containing S. boulardii or Lactobacillus reuteri (DSMZ 17648 strain) improved the eradication rate of H. Pylori infection, but it was not statistically significant. Therefore, it is recommended to conduct future research with a larger sample size to investigate the effect of S. boulardii supplementation on eradicating H. pylori infection and reducing treatment side effects.Trial registration: IRCT20200106046021N1, this trial was registered on Jan 14, 2020.

Consumption of fermented milk (FM) containing a probiotic, Lactobacillus gasseri SBT2055 (LG2055), previously showed a reduction in abdominal adiposity in a randomised controlled trial (RCT) using FM with 108 colony-forming units (cfu) of LG2055/g. However, whether the effectiveness is observed at lower concentrations, the recommended minimum or intermediate levels of probiotics (106 or 107cfu/g, respectively), remains to be examined. A multi-centre, double-blind, parallel-group RCT was conducted using 210 healthy Japanese adults with large visceral fat areas (80·2–187·8 cm2). They were balanced for their baseline characteristics and randomly assigned to three groups receiving FM containing 107, 106 or 0 (control) cfu LG2055/g of FM, and were asked to consume 200 g FM/d for 12 weeks. Abdominal visceral fat areas, which were determined by computed tomography, at week 12, changed from baseline by an average of − 8·5 % (95 % CI − 11·9, − 5·1; P< 0·01) in the 107 dose group, and by − 8·2 % (95 % CI − 10·8, − 5·7; P< 0·01) in the 106 dose group. Other measures including BMI, waist and hip circumferences, and body fat mass were also significantly decreased from baseline at week 12 in both groups; interestingly, the cessation of taking FM for 4 weeks attenuated these effects. In the control group, none of these parameters significantly decreased from baseline. These findings demonstrate that consumption of LG2055 at doses as low as the order of 108cfu/d exhibited a significant lowering effect on abdominal adiposity, and suggest that constant consumption might be needed to maintain the effect.
