Front Microbiol 2024; 15:1451563. [PMID: 39234535 PMCID: PMC11371576 DOI: 10.3389/fmicb.2024.1451563] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2024] [Accepted: 07/17/2024] [Indexed: 09/06/2024] Open
Abstract
The resistance of Helicobacter pylori (H. pylori) has increased in recent years, prompting a trend in the research and development of new drugs. In our study, three derivatives (JF-1, JF-2, and JF-3) were synthesized using 6-gingerol as the main component, while JF-4, containing both 6-gingerol and 6-shogaol as the main components, was extracted from dried ginger. The minimum inhibitory concentrations (MICs), determined using the ratio dilution method, were 80 μg/mL for JF-1, 40 μg/mL for JF-2, 30 μg/mL for JF-3, 40 μg/mL for JF-4, 60 μg/mL for 6-gingerol standard (SS), and 0.03 μg/mL for amoxicillin (AMX). After treating H. pylori-infected mice, the inflammation of the gastric mucosa was suppressed. The eradication rate of H. pylori was 16.7% of JF-3 low-dose treatment (LDT), 25.0% of JF-3 high-dose treatment (HDT), 16.7% of JF-4 LDT, 16.7% of JF-4 HDT, 30% of SS LDT, 50% of SS HDT, and 36.4% of the positive control group (PCG). The levels of gastrin, somatostatin (SST), IFN-γ, IL-4, and IL-8 were significantly recovered in the JF-3 and JF-4 administration groups, but the effect was stronger in the high-dose group. These results demonstrate that 6-gingerol and its derivatives have significant anti-Helicobacter pylori effects and are promising potential treatments for H. pylori infection.

Comparison of Levofloxacin-Based, 10-day Sequential Therapy with 14-day Quadruple Therapy for Helicobacter Pylori Eradication: A Randomized Clinical Trial. Middle East J Dig Dis 2018; 10:242-248. [PMID: 31049172 PMCID: PMC6488509 DOI: 10.15171/mejdd.2018.117] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2018] [Accepted: 09/02/2018] [Indexed: 02/06/2023] Open
Abstract
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.

Abstract
Background/Aims Moxifloxacin-based sequential therapy showed an excellent eradication rate as the first line treatment of Helicobacter pylori (H. pylori) infection. However, to the best of our knowledge, there were only a few studies on the treatment of those with failed moxifloxacin-based sequential therapy. Hence, this study was to investigate the efficacy of bismuth-containing quadruple therapy in those with failed moxifloxacin-based sequential or reverse sequential therapy for H. pylori eradication. Methods Between January 2013 and March 2016, we retrospectively analyzed patients who failed to eradicate H. pylori using moxifloxacin-based sequential (rabeprazole 20 mg bid and amoxicillin 1 g bid for 5-7 days, followed by rabeprazole 20 mg bid, metronidazole 500 mg bid, and moxifloxacin 400 mg qd for 5-7 days) and 10 days moxifloxacin-based reverse sequential therapy as the first line treatment. Then we investigated the eradication rates of bismuth-containing quadruple therapy as the second line treatment. All subjects had no history of H. pylori eradication before. Eradication rates were described as intention-to-treat (ITT) and per-protocol (PP) analyses. H. pylori status was evaluated by ¹³C-urea breath test 6 weeks after the end of the treatment. Moreover, we examined any side effects that caused discontinuation of therapy. Results Twenty-three patients received bismuth-containing quadruple therapy as the second line treatment. The overall eradication rates by ITT and PP analyses were 60.87% (n=14/23) and 73.68% (n=14/19). All the patients showed good compliance, and there were no serious adverse events. Conclusions Bismuth-containing quadruple therapy is insufficient as the second line eradication treatment after a failed attempt of moxifloxacin-based sequential or reverse sequential therapy. Large-scale clinical trials should be performed to establish better clinical evidence.

Efficacy of three-in-one capsule bismuth quadruple therapy for Helicobacter pylori eradication in clinical practice in a multinational patient population. Helicobacter 2017; 22.

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.
