Abstract
Vonoprazan, a novel acid suppressant and the first potassium-competitive acid blocker, has the potential to enhance the eradication rate of Helicobacter pylori due to its robust acid-suppressing capacity. This study aimed to compare the efficacy of vonoprazan-based dual therapy (vonoprazan-amoxicillin, VA) with vonoprazan-based bismuth quadruple therapy (VBQT) as a first-line treatment for H pylori infection. This retrospective single-center non-inferiority study was conducted in China. Treatment-naive H pylori-positive patients aged 18 to 80 received one of the 2 treatment regimens at our center. The VA group received vonoprazan 20 mg twice daily and amoxicillin 1000 mg 3 times daily for 14 days, whereas the VBQT group received vonoprazan 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and bismuth potassium citrate 220 mg twice daily for 14 days. The eradication rate was evaluated 4 to 6 weeks after treatment using the carbon-13/14 urea breath test. Propensity score matching was used to analyze eradication rates, adverse events (AEs), and patient compliance between the 2 groups. Initially, 501 patients were included, and after propensity score analysis, 156 patients were selected for the study. Intention-to-treat analysis showed eradication rates of 87.2% (95% CI, 79.8-94.6%) for the VA group and 79.5% (95% CI, 70.5-88.4%) for the VBQT group (P = .195). Per-protocol analysis demonstrated rates of 94.4% (95% CI, 89.2-99.7%) for the VA group and 96.8% (95% CI, 92.4-100%) for the VBQT group (P = .507). Non-inferiority was confirmed between the 2 groups, with P values < .025. The VA group showed a lower rate of AEs (10.3% vs 17.9%, P = .250) compared to the VBQT group. There were no significant differences in patient compliance between the 2 groups. In treatment-naive patients with H pylori infection, both the 14-day VA and VBQT regimens demonstrated comparable efficacy, with excellent eradication rates. Moreover, due to reduced antibiotic usage, lower rate of AEs, and lower costs, VA dual therapy should be prioritized.

Abstract
OBJECTIVE We performed a meta-analysis to determine whether the addition of probiotics to the bismuth quadruple therapy (BQT) for Helicobacter pylori would improve the incidence of eradication and reduce that of side effects. METHODS Randomized controlled trials matching the inclusion criteria were collected from PubMed, Embase, Web of Science, and The Cochrane Central Register of Controlled Trials. A Mantel-Haenszel random-effects model was used to calculate pooled risk ratios (RRs) and 95% confidence intervals (CIs) for the incidences of eradication rate, side effects as a whole, diarrhea, and other side effects. RESULTS Ten studies were selected for inclusion in the meta-analysis. The pooled RRs for the eradication rates in intention-to-treat and per-protocol analyses of the probiotic group vs. the control group were 1.07 (95% CI: 1.02-1.11) and 1.04 (95% CI: 1.00-1.07), respectively. Probiotic supplementation reduced the incidences of side effects (RR 0.58, 95% CI: 0.37-0.91), diarrhea (RR 0.41, 95% CI: 0.25-0.67), and bitter taste (RR 0.63, 95% CI: 0.40-0.99). CONCLUSIONS The results of this meta-analysis support the use of probiotics in combination with BQT in the clinical management of patients with H. pylori infection.

Abstract
Background Until now, there is little evidence regarding clinical efficacy of 14-day vonoprazan-based bismuth quadruple therapy (BQT) for Helicobacter pylori (H. pylori) eradication. Methods Overall, 65 treatment-naïve patients with H. pylori infection who received 14-day vonoprazan-based BQT regimen (VBCA, n=17) or pantoprazole-based BQT regimen (PBCA, n=48) for H. pylori eradication were retrospectively included. Results Neither successful H. pylori eradication (88.2% versus 91.7%, p=1.000) nor adverse event (52.9% versus 64.6%, p=0.397) was significantly different between VBCA and PBCA groups. Conclusion Vonoprazan seems to be as effective and safe as pantoprazole during a 14-day BQT regimen in treatment-naïve patients with H. pylori infection.

Abstract
A standard bismuth quadruple therapy, a fluoroquinolone-containing triple (or quadruple) therapy or a proton pump inhibitor (PPI)-amoxicillin high-dose dual therapy has been recommended as a second-line treatment for Helicobacter pylori infection by the Maastricht VI/Florence Consensus Report. The major shortcoming of levofloxacin-amoxicillin triple therapy is low cure rate for eradicating levofloxacin-resistant strains. With the rising prevalence of levofloxacin-resistant strains, levofloxacin-amoxicillin triple therapy cannot reliably achieve a high eradication rate for second-line treatment of H. pylori infection in most countries now. The present article aims to review current second-line eradication regimens with a per-protocol eradication rate exceeding 85% in most geographic areas. Recently, a novel tetracycline-levofloxacin quadruple therapy consisting of a PPI, bismuth, tetracycline, and levofloxacin for rescue treatment of H. pylori infection has been developed. The new therapy achieved a higher per-protocol eradication rate than levofloxacin-amoxicillin triple treatment in a randomized controlled trial (98% versus 69%). Additionally, the tetracycline-levofloxacin quadruple therapy also exhibits a higher eradication rate than amoxicillin-levofloxacin quadruple therapy. High-dose dual PPI-amoxicillin therapy is another novel second-line treatment for H. pylori infection. The new therapy can achieve an eradication rate of 89% by per-protocol analysis for the second-line treatment in Taiwan. Recently, levofloxacin-based sequential quadruple therapy and potassium-competitive acid blocker have also been applied in the second-line treatment of H. pylori infection. A meta-analysis revealed that a vonoprazan-based regimen has significant superiority over a PPI-based regimen for second-line H. pylori eradication therapy. In conclusion, the eradication rate of levofloxacin-amoxicillin triple therapy is suboptimal in the second-line treatment of H. pylori infection now. Currently, a standard bismuth quadruple therapy (tetracycline-metronidazole quadruple therapy), a tetracycline-levofloxacin quadruple therapy, an amoxicillin-levofloxacin quadruple therapy, a levofloxacin-based sequential quadruple therapy or a high-dose PPI-amoxicillin dual therapy is recommended for the second-line treatment of H. pylori infection.

Abstract
BACKGROUND We compared the efficacy and safety of rifabutin-containing triple therapy with bismuth quadruple therapy for rescue treatment of Helicobacter pylori. METHODS This was a noninferiority study trial of H. pylori treatment for subjects who had failed at least 2 prior treatments. Subjects were randomly assigned to receive rifabutin triple therapy with 14-day esomeprazole (20 mg), amoxicillin (1.0 g), and rifabutin (150 mg) twice a day; or bismuth quadruple therapy with esomeprazole (20 mg) and bismuth (220 mg) twice a day, plus metronidazole (400 mg) and tetracycline (500 mg) 4 times a day. Antimicrobial susceptibility was assessed by agar dilution and E-test. RESULTS From May 2021 to October 2022, a total of 364 subjects were randomized. The eradication rates by intention-to-treat, per-protocol, and modified intention-to-treat were 89.0% (162/182; 95% confidence interval [CI], 83.6%-92.8%), 94.0% (157/167; 95% CI, 89.3%-96.7%), and 93.6% (162/173; 95% CI, 89.0%-96.4%) for rifabutin triple group. For bismuth quadruple group, they were 89.6% (163/182; 95% CI, 84.3%-93.2%), 95.3% (143/150; 95% CI, 90.7%-97.7%), and 93.7% (163/174; 95% CI, 89.0%-96.4%). CONCLUSIONS The rifabutin triple therapy is an alternative to classical bismuth quadruple therapy for the rescue treatment of H. pylori with fewer side effects and higher compliance.

Abstract
Background With the increase in antibiotic resistance, the success rate of Helicobacter pylori (H. pylori) eradication therapy has declined in recent years. Vonoprazan-amoxicillin (VA) dual therapy has been reported to be a promising regimen. Objectives To compare the efficacy and safety of VA dual therapy and bismuth quadruple therapy containing amoxicillin and clarithromycin for H. pylori first-line eradication, and to further analyze the effects of clarithromycin resistance on eradication rate. Design This study was a single-center, open-label, randomized controlled trial. Methods Treatment-naïve H. pylori-infected patients were randomly allocated 1:1 to the VA group (vonoprazan 20 mg twice daily and amoxicillin 750 mg four times daily, for 14 days) or the RBAC group (rabeprazole 10 mg, bismuth potassium citrate 220 mg, amoxicillin 1000 mg and clarithromycin 500 mg twice daily, for 14 days). H. pylori clarithromycin resistance and CYP2C19 gene polymorphisms were detected with real-time polymerase chain reaction (PCR) technique. The eradication rates and adverse events were analyzed. Results A total of 151 patients were enrolled. The intention-to-treat (ITT), modified intention-to-treat (mITT), and per-protocol (PP) eradication rates and their 95% confidence intervals (95% CIs) were 94.6% (86.0-98.3%), 98.6% (91.3-99.9%), and 98.5% (90.9-99.9%) for VA group and 87.0% (77.0-93.3%), 91.8% (82.3-96.6%), and 93% (83.7-97.4%) for RBAC group. The eradication rate of the VA group was noninferior to the RBAC group in ITT, mITT, and PP analyses (p < 0.0001). In patients infected with strains of clarithromycin resistance point mutation, the eradication rate of the RBAC group decreased to lower than 90%, but the difference from the VA group did not achieve statistical significance (ITT eradication rate: 81.5% in the RBAC group and 96.2% in the VA group, p = 0.192). The incidence of adverse events in the VA group was 39.2%, which was significantly lower than that in the RBAC group (79.2%, p = 0.000). Conclusion The efficacy of VA dual therapy is noninferior to RBAC in H. pylori first-line eradication, with fewer adverse reactions. Registration This study was registered at the Chinese Clinical Trial Registry (ChiCTR2100052550) on 30 October 2021.

Abstract
(1) Background: Whether standard bismuth quadruple therapy (BQT) is superior to concomitant therapy for the first-line treatment of Helicobacter (H.) pylori infection is unclear. The aim of this systematic review and meta-analysis was to compare the efficacy of standard BQT versus concomitant therapy for H. pylori eradication in subjects naïve to treatment. (2) Methods: Online databases were searched for randomized controlled trials. We pooled risk ratio (RR) of individual studies for dichotomous outcomes using a random-effect model. (3) Results: Six studies with 1810 adults were included. Overall intention-to-treat (ITT) eradication rate was 87.4% with BQT and 85.2% with concomitant therapy (RR 1.01, 95%CI:0.94-1.07). Subgroup analysis of five Asian studies showed a small but significant superiority of BQT over concomitant therapy (87.5% vs. 84.5%; RR 1.04, 95%CI:1.01-1.08). Pooling four studies at low risk of bias yielded a similar result (88.2% vs. 84.5%; RR 1.05, 95%CI:1.01-1.09). There was no difference between the regimens in the frequency of adverse events (RR = 0.97, 95%CI:0.79-1.2). (4) Conclusions: The efficacy of BQT seems to be similar to concomitant therapy, with similar side effect profile. However, BQT showed a small but significant benefit over concomitant therapy in Asian populations and in studies at low risk of bias.

Abstract
BACKGROUND Given the general unavailability, common adverse effects, and complicated administration of tetracycline, the clinical application of classic bismuth quadruple therapy (BQT) is greatly limited. Whether minocycline can replace tetracycline for Helicobacter pylori ( H . pylori ) eradication is unknown. We aimed to compare the eradication rate, safety, and compliance between minocycline- and tetracycline-containing BQT as first-line regimens. METHODS This randomized controlled trial was conducted on 434 naïve patients with H . pylori infection. The participants were randomly assigned to 14-day minocycline-containing BQT group (bismuth potassium citrate 110 mg q.i.d., esomeprazole 20 mg b.i.d., metronidazole 400 mg q.i.d., and minocycline 100 mg b.i.d.) and tetracycline-containing BQT group (bismuth potassium citrate/esomeprazole/metronidazole with doses same as above and tetracycline 500 mg q.i.d.). Safety and compliance were assessed within 3 days after eradication. Urea breath test was performed at 4-8 weeks after eradication to evaluate outcome. We used a noninferiority test to compare the eradication rates of the two groups. The intergroup differences were evaluated using Pearson chi-squared or Fisher's exact test for categorical variables and Student's t -test for continuous variables. RESULTS As for the eradication rates of minocycline- and tetracycline-containing BQT, the results of both intention-to-treat (ITT) and per-protocol (PP) analyses showed that the difference rate of lower limit of 95% confidence interval (CI) was >-10.0% (ITT analysis: 181/217 [83.4%] vs . 180/217 [82.9%], with a rate difference of 0.5% [-6.9% to 7.9%]; PP analysis: 177/193 [91.7%] vs . 176/191 [92.1%], with a rate difference of -0.4% [-5.6% to 6.4%]). Except for dizziness more common (35/215 [16.3%] vs . 13/214 [6.1%], P = 0.001) in minocycline-containing therapy groups, the incidences of adverse events (75/215 [34.9%] vs . 88/214 [41.1%]) and compliance (195/215 [90.7%] vs . 192/214 [89.7%]) were similar between the two groups. CONCLUSION The eradication efficacy of minocycline-containing BQT was noninferior to tetracycline-containing BQT as first-line regimen for H . pylori eradication with similar safety and compliance.

Abstract
Helicobacter pylori is among the prevalent causes of infections worldwide, and its resistance rate to antibiotics has been rising over time. Amoxicillin is the cornerstone for the treatment regimen. However, the prevalence of penicillin allergy ranges from 4% to 15%. In patients with true allergy, Vonoprazan-Clarithromycin-Metronidazole and bismuth quadruple therapy have demonstrated excellent eradication and high adherence rates. Vonoprazan-based therapy is administered less frequently and may be better tolerated than bismuth quadruple therapy. Therefore, vonoprazan-based therapy may be considered as a first-line therapy if accessible. Bismuth quadruple therapy can be used as the initial therapy when vonoprazan is unavailable. Levofloxacin or sitafloxacin-based regimens achieve a moderately high eradication rate. However, these are associated with potentially serious adverse effects and should only be used when other effective and safer regimens are unavailable. Cephalosporins such as cefuroxime have been used as an alternative to amoxicillin. Microbial susceptibility studies can guide the selection of appropriate antibiotics. PPI-Clarithromycin-Metronidazole fails to achieve a high eradication rate and should be used as a second-line therapy. PPI-Clarithromycin-Rifabutin should not be used because of low eradication rate and frequent adverse reactions. The choice of the most effective antibiotic regimen can enhance clinical outcomes in patients with H. pylori infection and penicillin allergy.

Abstract
BACKGROUND Currently, bismuth quadruple therapy (BQT) is indicated as a first-line treatment for Helicobacter pylori eradication in areas with high dual metronidazole and clarithromycin resistance, with its use being limited by its low tolerability and significant cost. A novel regimen with high-dose amoxicillin dual therapy (HDADT) has emerged as an alternative. The aim of this study was to compare the results of these two treatments on HP eradication. MATERIALS AND METHODS Prospective randomized study including 100 consecutive patients undergoing H. pylori eradication. Each patient was randomized (in a 1:1 ratio) to one group of treatment: BQT (bismuth 140 mg + metronidazole 125 mg + tetracycline 125 mg, four times a day, for 10 days) or HDADT (amoxicillin 1000 mg alternating with amoxicillin 500 mg, four times a day, for 14 days), both associated with esomeprazole 40 mg twice a day. The primary aim was to compare treatments' efficacies. Secondary aims were to assess symptoms persistence and tolerability. RESULTS A total of 100 patients were included, 54% women, with a mean age of 55 ± 14 years. From these, five were lost to follow-up. Effective eradication proven by negative stool antigen test was significantly higher in patients randomized to HDADT when compared to BQT for both intention-to-treat (ITT) (96.2% vs. 81.4%; p = .022) and per-protocol (PP) (95.9% vs. 81%; p = .025) analysis. These differences were even more pronounced when only considering second line treatment (100% vs. 62.5%; p = .028). Side effects did not differ significantly between BQT and HDADT groups for both ITT (7.0% vs. 2.0%; p = .254) and PP (4.8% vs. 0%; p = .210) analysis. CONCLUSIONS When compared to BQT, treatment with HDADT presented higher and near 100% efficacy in eradicating H. pylori, without differences in reported side effects or compliance. This treatment represents an important alternative for populations with increasing incidences of resistance to the currently recommended antibiotic regimens.

Abstract
BACKGROUND Due to general unavailability and common side effects of tetracycline, the clinical application of bismuth quadruple therapy (BQT) is greatly limited. Whether amoxicillin can replace tetracycline in BQT remains unknown. This study aimed to compare the eradication rate, safety and compliance between amoxicillin-containing and tetracycline-containing BQT as a first-line regimen for Helicobacter pylori eradication. METHODS This randomized trial was conducted on 404 naïve patients for H. pylori eradication. The participants were randomly assigned to 14-day amoxicillin-containing (bismuth potassium citrate 110 mg four times/day, esomeprazole 20 mg twice daily, metronidazole 400 mg four times/day and amoxicillin 500 mg four times/day) and tetracycline-containing (tetracycline 500 mg four times/day and the other three drugs used as above) BQT. Safety and compliance were assessed within 3 days after eradication. Urea breath test was performed 4-8 weeks after eradication to evaluate outcome. RESULTS As for the eradication rates of amoxicillin-containing and tetracycline-containing BQT, the results of both intention-to-treat and per-protocol analyses showed that the difference rate of the lower limit of 95% confidence interval was above -10.0% (intention-to-treat analysis: 81.7% vs. 83.2%, with a rate difference of -1.5% [-6.3% to 9.3%]; per-protocol analysis: 89.0% vs. 91.6%, -2.6% [-4.1% to 9.3%]). The incidence of adverse events in amoxicillin-containing BQT was significantly lower than tetracycline-containing BQT (29.5% vs. 39.7%). Both groups achieved relatively good compliance (92.0% vs. 89.9%). CONCLUSION The eradication efficacy of amoxicillin-containing BQT was non-inferior to tetracycline-containing BQT as a first-line regimen for H. pylori eradication with better safety and similar compliance.

Abstract
Objective: The present study aims to compare the safety and efficacy of an amoxicillin/ilaprazole regimen with a bismuth quadruple regimen as the first-line treatment for eradicating Helicobacter pylori (H. pylori) infection. Methods: This was an open-label, randomized, single-center study involving 450 patients with untreated H. pylori infection who were randomly assigned to an Ilaprazole-amoxicillin-furazolidone-bismuth glycyrrhizinate (IAFB) quadruple therapy group for 14 days, a bismuth quadruple therapy group for 10 days, or Ilaprazole-amoxicillin (IA) dual therapy group for 14 days. The 13C urea breath test determined that H. pylori had been eliminated 4–6 weeks after treatment. For patients who failed the first treatment, mucosal tissues (two gastric antrum and one gastric body) were taken under gastroscope for the culture of H. pylori, drug sensitivity, the CYP2C19 gene, and globular degeneration. Results: In the intention-to-treat analysis, the eradication rates of H. pylori in the IAFB-14-day group, the IAFB-10-day group, and the IA-14-day group were 84.0, 79.3, and 88.0%, respectively. In the per-protocol analysis, the eradication rates in the three groups were 94.7, 87.5, and 93.0%, respectively. The resistance rates of patients who failed H. pylori eradication were 68.9% (22/32) for amoxicillin, 90.6% (29/32) for clarithromycin, 68.9% (22/32) for metronidazole, and 87.5% (28/32) for levofloxacin, and the extensive metabolizers of CYP2C19 polymorphism were 59.3% (19/32), the intermediate metabolizers were 34.4% (11/32), and the poor metabolizers were 6.3% (2/32). Conclusion: For newly treated patients with H. pylori infection in China, the efficacy of IA therapy for 14 days was similar to IAFB quadruple therapy for 10 or 14 days with better compliance and less cost. Therefore, these therapies can be considered first-line regimens for empirical treatment. Clinical Trial Registration: [http://www.chictr.org.cn/searchproj.aspx], identifier [ChiCTR2100052308].

Abstract
Background Bismuth quadruple therapy (BQT) is recommended as empirical first-line therapy because it is not affected by antibiotic resistance. We examined whether past exposure to metronidazole affected BQT outcomes. Methods The records of seven hospitals were searched for patients who received BQT for Helicobacter pylori eradication between 2009 and 2020. The association between past metronidazole exposure and the eradication rate was evaluated. Results This study was a multicenter retrospective study. Around 37,602 people tested for H. pylori infection were identified, and 7,233 received BQT. About 2,802 (38.7%) underwent a 13C-urea breath test to confirm eradication. The BQT efficacy was 86.4% among patients without metronidazole exposure and 72.8% among patients with exposure (p < 0.001). The eradication rate of BQT 14 days in patients with past exposure was higher than that of BQT <14 days (85.5 vs. 66.0%, p = 0.009). Multivariate analysis revealed that past metronidazole exposure [odds ratio (OR) 2.6, 95% CI 1.8–3.7; p < 0.001] and BQT <14 days (OR 1.5, 95% CI 1.2–2.0; p = 0.002) were independent risk factors for eradication failure. Conclusion Past metronidazole exposure significantly lowered the BQT eradication rate. BQT 14 days should be recommended for patients with suspected metronidazole exposure.

Abstract
BACKGROUND We previously reported that the administration of 14-day standard triple therapy (TT), sequential therapy (ST), bismuth-based quadruple therapy (BT), and concomitant therapy (CT) as the first-line therapy for Helicobacter pylori infection in Chinese children achieved eradication rates of 74.1%, 69.5%, 89.8%, and 84.6%, respectively. In this follow-up study, we further evaluated the short- and long-term effects of the four regimens on the gut microbiota in these children. METHODS We prospectively recruited treatment-naïve children with H. pylori infection. Fecal samples were collected at week 0, 2, 6, and 52, and alterations in the gut microbiota were analyzed by 16S rRNA gene sequencing. RESULTS Sixty-three patients participated in this study (16 with TT, 15 with ST, 16 with BT and 16 with CT). At week 2, the alpha diversity (Shannon and Chao 1 index) was significantly reduced in the TT (p = 0.008, p < 0.001), ST (p < 0.001, p < 0.001), BT (p < 0.001, p < 0.001) and CT groups (p < 0.001, p < 0.001). Some changes persisted in the ST, BT, and CT groups at week 6, and all were restored (expect p = 0.02 with Chao 1 index in the CT group) at week 52. The beta diversity was significantly changed in the BT (p = 0.001) and CT groups (p = 0.001) 2 weeks post-eradication and restored 1 year after therapy. Immediately after therapy, the relative abundance of Proteobacteria was strikingly increased in the ST (p = 0.005), BT (p < 0.001) and CT groups (p < 0.001), and the genus-level analysis showed that the abundances of 23.1%, 43.3%, 78.6%, and 78% of the bacterial genera in the TT, ST, BT, and CT groups were significantly changed. All these changes returned to almost the pre-eradication level 1 year post-eradication. CONCLUSION Eradication of H. pylori infection can lead to transient dysbiosis of gut microbiota, and these changes almost recovered 1 year post-eradication, which indicates the long-term safety of H. pylori therapy.

Abstract
Background and aim: Bismuth quadruple therapy (BQT) or non-bismuth quadruple therapy (i.e., concomitant therapy) (CT) is the first-line regimens to eradicate H. pylori infection in areas with high prevalence of clarithromycin (CLA) resistance. Guidelines suggest that in areas of high prevalence of H. pylori strains with double resistance (i.e., CLA + metronidazole), BQT should be preferred to CT. The aim of this study was to evaluate the efficacy and safety of BQT administered through the three-in-one pill (Pylera) formulation in a large series of H. pylori–infected patients, naive to treatment in a region with high CLA and dual resistance. Patients and methods: We treated 250 patients (148 F and 102 M, mean age 48.6 years) with H. pylori infection naïve to treatment. Patients received esomeprazole 40 mg bid and Pylera 3 tablets qid for 10 days. Diagnosis of H. pylori infection was through 13C urea breath test (13C UBT), or stool antigen test or histology, as appropriate. The evaluation of eradication was through 13C UBT at least 45 days after the end of therapy. Incidence of treatment-related adverse events (TRAEs) was assessed through a questionnaire at the end of treatment. Compliance was considered good if at least 90% of medication had been taken. Statistical analysis was per intention-to-treat e per protocol (PP). 95% confidence intervals (CIs) were calculated. Results: 1) 13 patients (5.2%) discontinued therapy due to side effects; 2) eradication rates in ITT and PP were 227/250 (90.8%; 95% CI 86.3–93.7%) and 226/237 (95.3%; 95% CI 91–99%), respectively; 3) the prevalence of TRAEs was 26.8%; and 4) adherence to treatment was good with compliance greater than 90%. Conclusion: In this real-life study, we demonstrate that in an area with a high prevalence of H. pylori strains with CLA or CLA + metronidazole resistance, BQT using Pylera is an effective therapeutic strategy with ITT eradication rates higher than 90%; this therapy is associated with good compliance and low incidence of side effects.

Abstract
BACKGROUND Penicillin-allergic children who are infected with Helicobacter pylori constitute a relatively common subgroup. We aimed to study the short-term and long-term effects of bismuth quadruple therapy on gut microbiota in penicillin-allergic children. METHODS We prospectively recruited treatment-naive children with H pylori infection and H pylori-negative asymptomatic children as healthy controls. Patients received 14-day bismuth quadruple therapy consisting of omeprazole, clarithromycin, metronidazole, and bismuth. Fecal samples were collected at weeks 0, 2, 6, and 52. Alterations in the gut microbiota were analyzed by 16S rRNA gene sequencing. RESULTS Twenty-two subjects (14 gastritis patients, 8 duodenal ulcer patients) and 23 controls participated in this study. At week 2, alpha diversity was reduced in both gastritis (P < .05) and ulcer (except P = .16 with Chao 1 index) patients compared with baseline. Some changes persisted at week 6, and all were restored at week 52. Beta diversity was significantly altered 2 weeks after treatment in the gastritis and duodenal ulcer groups (P = .001, P = .002, respectively) and restored at weeks 6 and 52. The mean relative abundance of Bacteroidetes (P < .001, P = .005, respectively) decreased and that of Proteobacteria increased (P < .001, P = .03, respectively). All alterations recovered at week 6 and 52. In both the gastritis and ulcer groups at week 2, some beneficial bacteria were decreased including Bacteroides (P < .001 and P = .003), Faecalibacterium (P < .001 and P = .02), Phascolarctobacterium (P = .002 and P = .004), Roseburia ( P < .001 and P = .13), Bifidobacterium (P = .08 and P = .04), and Blautia (P < .001 and P = .002). Some detrimental bacteria were increased including Escherichia-Shigella (P < .001 and P = .19), Klebsiella (P < .001, and P = .09), Enterococcus (P < .001 and P = .007), and Streptococcus (P = .002 and P = .004). The changes returned to almost the pre-eradication level 1 year after therapy. CONCLUSION Bismuth quadruple therapy causes short-term dysbiosis of the gut microbiota. Most changes recovered 1-year post-eradication, indicating the long-term safety of H pylori therapy.

Abstract
BACKGROUNDS Due to the decreasing eradication rate of Helicobacter pylori, some novel alternatives have been developed, such as bismuth-containing quadruple therapy and non-bismuth-containing quadruple therapy (sequential and concomitant treatment). Little is known about whether a success rate above 90% can be achieved with these regimens in Chinese children. METHODS In this prospective, open, comparative cross-sectional study, we recruited treatment-naïve children (aged between 6 and 18 years) with H pylori infection. The patients were assigned either standard triple therapy, sequential therapy, bismuth-based quadruple therapy, or concomitant therapy at the discretion of the prescribing physician. H pylori infection was evaluated at least 4 weeks after the completion of the treatment. A negative urea breath test (UBT) indicated successful eradication. The primary endpoint was the eradication frequency of H pylori in the full analysis set (FAS), which included all children who received at least one dose of the treatment and with available follow-up data. RESULTS Between September 2017 and December 2018, 228 patients were finally included in the FAS analyses. The eradication rates were 74.1% for standard triple therapy (43/58, [95% CI: 62.8%-85.5%]), 69.5% for sequential therapy (41/59, [95% CI: 57.8%-81.2%]), 89.8% for bismuth-based quadruple therapy (53/59, [95% CI: 82.1%-97.5%]), and 84.6% for concomitant therapy (44/52, [95% CI: 74.8%-94.4%]). Bismuth-based therapy was superior to triple therapy, while sequential therapy and concomitant therapy were not superior to triple therapy. The frequency of adverse events was 12.1% (7/58) in standard triple therapy, 6.8% (4/59) in sequential therapy, 15.3% (9/59) in bismuth-based therapy, and 15.4% (8/52) in concomitant therapy. The rate of adverse events was similar among the four groups. CONCLUSION Bismuth quadruple therapy can achieve an eradication rate of 89.8% as first-line treatment and is safe and well tolerated. Bismuth could be a promising alternative as a first-line regimen in Chinese children.

Abstract
AIM The aim of this study was to perform a systematic review and meta-analysis on high-dose dual therapy (HDDT) versus bismuth quadruple therapy (BQT) for Helicobacter pylori infection. METHODS Comparing HDDT to BQT were identified from PubMed, EMBASE, Cochrane library, CNKI, and Wanfang databases in Chinese up to March 2018. Statistical analyses were conducted using Review Manager 5.3 to compare the efficacy and side effects of these 2 therapies for H pylori infection. Dichotomous data were pooled to score the relative risk (RR) with 95% confidence intervals (CIs). RESULTS Four randomized clinical trials (RCTs) including 829 patients with a diagnosis of H pylori infection were assessed. Overall the meta-analysis showed that both HDDT and BQT achieved similar efficacy of intention-to-treat (ITT) eradication rate, 85.5% versus 87.2%, RR 1.01 (95% CI: 0.96-1.06), P = .63, and of per-protocol (PP) eradication rate, 88.4% versus 91.5%, RR 1.00 (95% CI: 0.96-1.04), P = .99, and adherence 97.8% versus 95.0%, RR 1.01 (95% CI: 0.99-1.04), P = .32, but side effects were more likely in BQT (14.4% vs 40.4%, RR 0.42 (95% CI: 0.32-0.54), P <.00001). CONCLUSION Both HDDT and BQT can achieve similar eradication rate for H pylori infection and adherence, and generally HDDT causes fewer side effects.

Abstract
BACKGROUND Bismuth quadruple therapy is the treatment of choice for the first-line therapy of Helicobacter pylori infection in areas of high clarithromycin resistance. Currently, the impact of the promising treatment on gut microbiota remains unclear. AIM To investigate the short-term and long-term impacts of bismuth quadruple therapy on gut microbiota. METHODS Adult patients with H. pylori-related gastritis were treated with 14-day bismuth quadruple therapy. Fecal samples were collected before treatment at week 2, week 8, and week 48. Nucleic acid extraction from fecal samples was performed. The V3-V4 region of the bacterial 16S rRNA gene was amplified by polymerase chain reaction and sequenced with the MiSeq followed by data analysis using Qiime pipeline. RESULTS Eleven patients received complete follow-up. Before treatment, the most abundant phyla were Firmicutes (45.3%), Bacteroidetes (24.3%), Proteobacteria (9.9%), and Actinobacteria (5.0%). At the end of bismuth therapy, the relative abundances of Bacteroidetes and Actinobacteria decreased to 0.5% (P < .001) and 1.3% (P = .038), respectively. Additionally, the relative abundance of Verrucomicrobia also decreased from 3.2% to 1.11E-3% (P = .034). In contrast, the relative abundances of Proteobacteria and Cyanobacteria increased (P < .001 and P = .003, respectively). At week 8, the relative abundances of all phyla restored to the levels at baseline. The relative abundances of all phyla at week 48 also did not significantly differ from those at baseline. During eradication therapy, 6 patients (55%) reported at least 1 adverse event. The relative abundance of phylum Proteobacteria in patients with adverse effects was more than that in patients without adverse effects (68.7% ± 8.8% vs 43.4% ± 25.5%; P = .048). CONCLUSIONS Bismuth quadruple therapy for H. pylori eradication can lead to short-term dysbiosis of gut microbiota. The increase in Proteobacteria in gut microbiota may attribute to the development of adverse effects during bismuth quadruple therapy.

Abstract
BACKGROUND Clinical trials have shown a good efficacy of the "three-in-one" formulation of bismuth quadruple therapy (BQT) for Helicobacter (H.) pylori eradication. We aimed to assess the efficacy and safety of the three-in-one BQT in clinical practice, and investigate the effect of probiotic supplementation, in Italy. MATERIALS AND METHODS A retrospective database, multicentre observational study was conducted in seven Italian Hospitals. Consecutive H. pylori-positive patients who received the three-in-one BQT for 10 days were included in the analysis. H. pylori eradication was assessed by histology, 13 C-urea breath test, or stool antigen test. Compliance and adverse events were evaluated by interview. RESULTS A total of 376 patients were included in the intention-to-treat (ITT) and 352 in the per protocol (PP) analyses. One hundred and ninety-three subjects received probiotics supplementation. Overall, eradication rates were 90.2% (95% Confidence Interval (CI):86.7-93.0) in ITT and 94.6% (95% CI: 91.7-96.7) in PP analyses. The compliance was good (≥90% of treatment taken) in 94.9% of patients. The proportion of patients with a good compliance was not different with and without probiotics supplementation (94.8% vs 95.1%). Eradication rates were equally high for first-line (91.4%), second-line (87.5%), and third-line treatments (91.7%) in the ITT analysis (P = .48). Adverse events were reported by 32.4% of patients, but only 6.1% of patients discontinued treatment. CONCLUSIONS The three-in-one BQT is highly effective and well tolerated for H. pylori eradication in daily clinical practice. Probiotics supplementation fails to improve compliance.

Abstract
Background In order to mitigate potential issues with antibiotic resistance in the treatment of patients with Helicobacter pylori infection, the selection of a therapeutic regimen is optimized by being aware of local eradication rates as well as the patient’s medication history and previous diagnoses. Purpose This study primarily aimed to calculate the eradication rate of H. pylori infection in the New York Metropolitan area when using clarithromycin-based triple therapy per the dosing instructions for Omeclamox®-Pak. A secondary objective was to determine risk factors for therapeutic failure. Patients and methods A retrospective analysis was performed on 156 patients treated with clarithromycin-based triple therapy between 2011 and 2017 at a gastroenterology practice in Edison, New Jersey. Results The cumulative eradication rate for the intent-to-treat population was 84%, while the per-protocol rate was 86%. No differences were seen in the rates of subgroups defined by demographics or medication history. Conclusion Despite evidence and predictions from other sources in the last decade that clarithromycin-based treatments for H. pylori are becoming less effective, the results of this study support the use of clarithromycin-based triple therapy as a first-line treatment in the New York Metropolitan region.

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

Abstract
BACKGROUND Bismuth quadruple therapy (BQT) is the recommended rescue therapy for Helicobacter pylori (H. pylori) infection. This study aimed to assess the efficacy and safety of a 10-day BQT regimen in patients who failed previous therapies and were infected with multiresistant H. pylori strains MATERIALS AND METHODS: Helicobacter pylori-infected patients underwent endoscopy, culture, and susceptibility test for clarithromycin, metronidazole, and levofloxacin. Treatment with three-in-one capsule (Pylera®) four times daily and esomeprazole 20 mg twice daily for 10 days was administered. Treatment-emergent adverse events (TEAEs) were registered. RESULTS A total of 116 patients with persistent H. pylori infection following at least one eradication therapy attempt were treated. Overall, resistance toward clarithromycin was detected in 80% of strains, toward metronidazole in 70%, and levofloxacin in 47.5%, with dual or triple resistance in 72.5% of cases. An eradication rate of 81.0% (95% CI: 73.0-87.1) and 87.0% (95% CI: 79.4-92.1) at ITT and PP analyses, respectively, was achieved. The cure rate remained high until it was used as fourth-line regimen, while it dropped to low values (<67%) in those patients with more than 4 therapy failures. A total of 65.7% (95% CI: 56.4-74.0) patients complained of TEAEs. CONCLUSIONS Our data found that bismuth-based quadruple regimen is effective as rescue therapy for curing patients infected with multiresistant H. pylori strains.

Abstract
Hybrid therapy is a novel two-step treatment achieving a high eradication rate for Helicobacter pylori infection. Currently, whether this new therapy achieves a higher eradication rate than bismuth quadruple therapy remains an unanswered question. The aim of this prospective, randomized comparative study was to investigate the efficacies of 14-day hybrid therapy and bismuth quadruple therapy in the treatment of H. pylori infection. From July 2013 to June 2015, eligible H. pylori-infected subjects were randomly assigned to receive either 14-day bismuth quadruple therapy (pantoprazole, bismuth subcitrate, tetracycline, and metronidazole for 14 days) or 14-day hybrid therapy (a 7-day dual therapy with pantoprazole plus amoxicillin, followed by a 7-day quadruple therapy with pantoprazole plus amoxicillin, clarithromycin, and metronidazole). H. pylori status was examined 6 weeks after the end of treatment. Three hundred thirty H. pylori-infected participants were randomized to receive 14-day bismuth quadruple therapy (n = 164) or 14-day hybrid therapy (n = 166). The eradication rates by intention-to-treat analysis were similar: 93.9% versus 92.8%, respectively (95% confidence interval [CI], -4.3% to 5.4%; P = 0.68). Per-protocol analysis yielded similar results (96.7% versus 94.9%, respectively; P = 0.44). However, bismuth quadruple therapy had a higher frequency of adverse events than hybrid therapy (55.5% versus 15.7%, respectively; 95% CI, 30.4% to 49.2%; P < 0.001). The two treatments exhibited comparable drug adherence (93.9% versus 97%, respectively). The resistance rates of antibiotics were: clarithromycin, 16.7% of patients; amoxicillin, 1.3%; metronidazole, 25%; and tetracycline, 0%. In the bismuth quadruple therapy group, the eradication rate of metronidazole-resistant strains was lower than that of metronidazole-susceptible strains (70.0% versus 96.4%, respectively; P = 0.04). In the hybrid therapy group, no significant impact of clarithromycin or metronidazole resistance on eradication rates was identified. Both 14-day hybrid and bismuth quadruple therapies cure most patients with H. pylori infection in populations with moderate antibiotic resistance. However, the 14-day hybrid therapy has fewer adverse effects than the bismuth quadruple therapy. (This study has been registered at ClinicalTrials.gov under identifier NCT02541864.).

Abstract
Helicobacter pylori (H. pylori) infection has been associated with gastric disorders. The situation of H. pylori infection in China-where a high prevalence of H. pylori infection, a high incidence of gastric cancer, and widespread resistance to clarithromycin, metronidazole, and levofloxacin exist-is quite different from that in Western countries. In order for Chinese clinicians to better manage H. pylori infection, a Chinese Study Group on H. pylori published four consensus reports regarding the management of H. pylori infection in China between 1999 and 2012. The eradication rate with standard triple therapy was <80% in most areas of China. Bismuth is available in China, and bismuth-containing quadruple therapy has been shown to produce a high eradication rate; thus, bismuth quadruple therapy could be recommended both as an initial and as a rescue therapy in China. There is no advantage of sequential therapy over triple therapy in Chinese patients, but the efficacy of concomitant therapy must be studied further. This review introduces the epidemiology, diagnosis, indicators, and therapies for the eradication of H. pylori in China in recent years.

Abstract
Helicobacter pylori is a gram-negative, microaerophilic spiral bacillus that is associated with life-threatening diseases such as gastric cancer, gastric MALT lymphoma, and peptic ulcer disease. The definition of an effective therapy is one that achieves at least a 90% eradication rate on a per-protocol basis with the first attempt. Eradication rates of H. pylori have declined to unacceptable levels worldwide, mostly due to antibiotic resistance and standard triple therapy gradually has lost its efficacy in most counties. However, bismuth quadruple therapy, when prescribed properly, has maintained its effectiveness. Alternative first-line regimens such as sequential and concomitant therapy were developed to substitute for standard triple therapy and were highly effective in the countries where they were developed, but proved susceptible to failure in regions with high rates of antibiotic resistance. Antibiotic resistance rates in Russia are high, however there is lack of data regarding comparative efficacy of first-line eradication options. The authors of this review extrapolate the knowledge of H. pylori first-line eradication options in Russia based on data from other countries, as well as from domestic studies. The available data support use of 14-day regimens with concomitant therapy, bismuth quadruple therapy, or furazolidone quadruple therapy for empiric use in adults. In addition, 14-day levofloxacin-containing therapies could be used if resistance is relatively low or lacking as triple therapy or possibly as a 5-day concomitant levofloxacin therapy.
