A Comparison between 10-day and 12-day Concomitant Regimens for Helicobacter Pylori Eradication: A Randomized Clinical Trial.

ABSTRACT: BACKGROUND Helicobacter pylori (H. pylori) infection is one of the most common bacterial infections worldwide, which is associated with peptic ulcer disease and gastric cancer. In this study, we compared the efficacy of 10-day versus 12-day concomitant therapy as the first-line treatment for H. pylori eradication in Iran. METHODS 218 patients with peptic ulcer disease and naïve H. pylori infection, were randomly divided into two groups to receive either 10-day or 12-day concomitant regimens, composed of pantoprazole 40 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and metronidazole 500 mg, all given twice daily. Eight weeks after treatment, H. pylori eradication was assessed by 14C- urea breath test. The trial was registered in the Iranian Registry of Clinical Trials (code: IRCT20170521034070N2). RESULTS 212 patients completed the study. According to the intention to treat analysis, the eradication rates were 83.6% (95% CI: 76.6-90.5) and 88.8% (95% CI: 82.8-94.7) in 10-day and 12-day concomitant therapy groups, respectively (p = 0.24). Per-protocol eradication rates were 85.9% (95% CI: 79.3-92.4) and 92.6% (95% CI: 87.6-97.5), respectively (p = 0.19). The rates of severe side effects were not statistically different between the two groups (3.6% vs. 8.1%; p = 0.428). CONCLUSION 12-day concomitant therapy could achieve ideal eradication rates by both intention to treat and perprotocol analyses. In order to reduce the cost of drugs and the rate of adverse effects of therapy, among 10-day and 12day regimens, 12-day concomitant therapy seems to be a good alternative to 14-day concomitant therapy that has been suggested by international guidelines.

Project description:BACKGROUND Considering the importance of Helicobacter pylori (H. pylori) eradication, this clinical trial was designed to prospectively evaluate the efficacy of levofloxacin-based, sequential therapy in comparison with quadruple therapy for eradicating H. pylori. METHODS Overall 156 patients with dyspepsia and H. pylori infection were included in this study and were randomly allocated to either 10-day sequential therapy group (group A) to receive pantoprazole (40 mg twice daily), amoxicillin (1 gr twice daily), levofloxacin (500 mg twice daily), and tinidazole (500 mg twice daily) (PALT) or 14-day quadruple therapy group (group B) to receive pantoprazole, clarithromycin, bismuth subcitrate, and amoxicillin (PABC). At the end of the study the eradication rate in each group was assessed by urea breath test (UBT). RESULTS Age range of the participants was 18-65 years (average 36.9 years) and 50% of them (78 patients) were men. 78 patients were allocated to group A and 78 patients to groupe B. After antibiotic therapy, all the patients received acid suppression therapy with Proton Pump Inhibitor (PPI) for 4 weeks and then the eradication rate was confirmed by UBT (Heli FAN plus 13C, Germany). Before performing UBT, all the participants were requested to halt consumption of PPI for at least 1 week. During the treatment there was not any major complication but in group A (sequential therapy), two patients complained of minor complications including musculoskeletal pain. None of the patients in group B had any complaint or side effect. The rate of H. pylori eradication in group A was 78.2% (61 patients) while this rate in group B was 83.3% (65 patients) with no significant difference between the two groups (p = 0.42). In subgroup analysis, the rate of eradication among men in group A and B were 76.9% and 89.7%, respectively (p = 0.22) while the eradication rate among women were 79.4% and 76.9%, respectively (p = 1.00). CONCLUSION It seems that levofloxacin base sequential therapy does not have any advantage in comparison with quadruple regimen and until finding any more effective short course therapy for H. Pylori eradication; we encourage quadruple regimen to be used as the first line therapy.

Project description:BackgroundEvidence from Europe, Asia, and North America suggests that standard three-drug regimens of a proton-pump inhibitor plus amoxicillin and clarithromycin are significantly less effective for eradication of Helicobacter pylori infection than are 5-day concomitant and 10-day sequential four-drug regimens that include a nitroimidazole. These four-drug regimens also entail fewer antibiotic doses than do three-drug regimens and thus could be suitable for eradication programmes in low-resource settings. Few studies in Latin America have been done, where the burden of H pylori-associated diseases is high. We therefore did a randomised trial in Latin America comparing the effectiveness of four-drug regimens given concomitantly or sequentially with that of a standard 14-day regimen of triple therapy.MethodsBetween September, 2009, and June, 2010, we did a randomised trial of empiric 14-day triple, 5-day concomitant, and 10-day sequential therapies for H pylori in seven Latin American sites: Chile, Colombia, Costa Rica, Honduras, Nicaragua, and Mexico (two sites). Participants aged 21-65 years who tested positive for H pylori by a urea breath test were randomly assigned by a central computer using a dynamic balancing procedure to: 14 days of lansoprazole, amoxicillin, and clarithromycin (standard therapy); 5 days of lansoprazole, amoxicillin, clarithromycin, and metronidazole (concomitant therapy); or 5 days of lansoprazole and amoxicillin followed by 5 days of lansoprazole, clarithromycin, and metronidazole (sequential therapy). Eradication was assessed by urea breath test 6-8 weeks after randomisation. The trial was not masked. Our primary outcome was probablity of H pylori eradication. Our analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, registration number NCT01061437.Findings1463 participants aged 21-65 years were randomly allocated a treatment: 488 were treated with 14-day standard therapy, 489 with 5-day concomitant therapy, and 486 with 10-day sequential therapy. The probability of eradication with standard therapy was 82·2% (401 of 488), which was 8·6% higher (95% adjusted CI 2·6-14·5) than with concomitant therapy (73·6% [360 of 489]) and 5·6% higher (-0·04% to 11·6) than with sequential therapy (76·5% [372 of 486]). Neither four-drug regimen was significantly better than standard triple therapy in any of the seven sites.InterpretationStandard 14-day triple-drug therapy is preferable to 5-day concomitant or 10-day sequential four-drug regimens as empiric therapy for H pylori infection in diverse Latin American populations.FundingBill & Melinda Gates Foundation, US National Institutes of Health.

Project description:AimTo compare the Helicobacter pylori (H. pylori) eradication rate of clarithromycin-based triple therapy, metronidazole-based triple therapy, sequential therapy and concomitant therapy.MethodsA total of 680 patients infected with H. pylori were divided into 4 groups and each group was treated with a different eradication therapy. Clarithromycin-based triple therapy was applied to the first group [rabeprazole, amoxicillin and clarithromycin (PAC) group: proton pump inhibitor (PPI), amoxicillin, clarithromycin], whereas the second group was treated with metronidazole-based triple therapy [rabeprazole, amoxicillin and metronidazole (PAM) group: PPI, amoxicillin, metronidazole]. The third group was treated with rabeprazole and amoxicillin, followed by rabeprazole, clarithromycin and metronidazole (sequential group). The final group was simultaneously treated with rabeprazole, amoxicillin clarithromycin and metronidazole (concomitant therapy group). In the case of a failure to eradicate H. pylori, second-line quadruple and third-line eradication therapies were administered.ResultsThe per protocol (PP) analysis was performed on 143, 139, 141 and 143 patients in the PAC, PAM, sequential and concomitant groups, respectively. We excluded patients who did not receive a C(13)-urea breath test (22, 20, 23 and 22 patients, respectively) and patients with less than an 80% compliance level (5, 11, 6 and 5 patients, respectively). The eradication rates were 76.2% (109/143) in the PAC group, 84.2% (117/139) in the PAM group, 84.4% (119/141) in the sequential group and 94.4% (135/143) in the concomitant group (P = 0.0002). All 14 patients who failed second-line therapy were treated with third-line eradication therapy. Among these 14 patients, 6 infections were successfully eradicated with the third-line therapy. Both PP and intention-to-treat analysis showed an eradication rate of 42.9% (6/14). In the PAC group, 3 of 4 patients were successfully cured (3/4, 75%); 2 of 2 patients in the PAM group (2/2, 100%) and 1 of 5 patients in the sequential group (1/5, 20%) were also cured. In the concomitant group, all 3 patients failed (0/3, 0%).ConclusionThe eradication rate for the concomitant therapy was much higher than those of the standard triple therapy or sequential therapy (ClinicalTrials.gov number NCT01922765).

Project description:BackgroundBismuth quadruple therapy is currently consensus recommendation for first-line Helicobacter pylori (H. pylori) treatment; however, the optimal duration is unknown. We compared the efficacy of 10-day bismuth quadruple therapy with that of 14-day bismuth quadruple therapy for first-line eradication.MethodsFor our multicentre, parallel randomised, open-label, and non-inferiority study, we recruited H. pylori treatment-naïve patients from one medical centre and one teaching hospital in Taiwan. Patients were randomly assigned (1:1) to receive 10-day (PBMT-10) or 14-day (PBMT-14) bismuth quadruple therapy. The primary outcome was the eradication rate as determined by intention-to-treat (ITT) and per-protocol (PP) analyses. The eradication rates between the two groups were compared using a one-sided α value of 0.025 and a non-inferiority margin of 7%. The secondary outcomes were the rate of adverse effects. The trial is registered with ClincialTrials.gov (NCT04527055).FindingsFrom August 3, 2020 to April 28, 2023, 313 H. pylori treatment-naïve patients (PBMT-10 = 157; PBMT-14 = 156) were enrolled. 35 patients were excluded from PP analyses. The eradication rates (95% CI) for PBMT-10 and PBMT-14 were respectively 92.4% (88.2%-96.5%) and 92.9% (88.9%-97.0%) by ITT analyses, and 97.9% (95.5%-100.0%) and 99.3% (97.8%-100.0%) by PP analyses. The eradication rates for PBMT-10 were non-inferior to those for PBMT-14 (absolute difference [lower boundary of the one-sided 97.5% CI] -0.6% [-6.7%], PNI = 0.020 in ITT analyses, -1.4% [-5.8%], PNI = 0.007 in PP analyses). The rates of overall adverse effects (54.1% versus 57.1%, P = 0.604) were similar between the two groups; nevertheless, the rates of dizziness (18.5% versus 34.0%, P = 0.003) and vomiting (4.5% versus 12.8%, P = 0.008) were lower in PBMT-10 than in PBMT-14.InterpretationThe 10-day bismuth quadruple therapy was non-inferior to the 14-day therapy as a first-line treatment for eradicating H. pylori infection and had no different rates of overall adverse effects, but less serious adverse events in terms of dizziness and vomiting.FundingThe National Science and Technology Council and Ministry of Health and Welfare, Taiwan.
