Filter by:As H. pylori eradication, we prepared a randomized controlled clinical trial whether tegoprazan-containing 10-day sequential treatment was effective compared to conventional PPI-containing 10-day sequential eradication therapy
Current guidelines have recommended classical bismuth-containing quadruple therapy including proton-pump inhibitor, bismuth, tetracycline, metronidazole as the empirical rescue therapy. However, tetracycline is clinically unavailable in China and the high frequency of adverse events of bismuth quadruple therapy often result in poor compliance, which limited the applicability of this recommendation. We previously showed that the efficacy of bismuth-containing quadruple therapy with minocycline and metronidazole was not inferior to classical bismuth quadruple therapy for refractory H. pylori infection, though also accompanied with high occurrence of adverse events.This study aimed to evaluate the efficacy and tolerability of four different regimens with minocycline and metronidazole compared to classical bismuth quadruple therapy for H. pylori rescue treatment in a real-world setting.
Describe the efficacy and safety of Orelabrutinib in the treatment of HP-positive gastric MALT lymphoma
Background：Helicobacter pylori infection is a well-established risk factor for peptic ulcer disease and gastric cancer. It's now a consensus of experts that H.pylori infection should be treated once it is recognized. Extended proton pump inhibitor (PPI)-based sequential therapy as one of the most commonly used first-line regimens provides a satisfactory eradication rate of 90.7% (95% CI, 87.4% - 94.0%). Nevertheless, its complexity of the "sequential" usage is sometimes confusing to the patients and may lead to treatment failure. The emerging new regimen - vonoprazan-based dual therapy, on the other hand, is another appealing choice with simplicity, and low pill burden. However, there's still no evidence regarding the use of vonoprazan-based dual therapy with high-dose amoxicillin (1000mg twice daily) as the first-line regimen in Taiwan. This study aimed to compare the efficacy of the current standard first-line regimen, sequential therapy, with that of vonoprazan-based dual therapy with high-dose Amoxicillin. Objectives: To compare the efficacy of the current standard first-line regimen, sequential therapy, with that of vonoprazan-based dual therapy, through a randomized controlled trial. Methods: Patients with H.pylori infection who was over 20 years old and agree to participate in the trial will be recruited. Those who had received H.pylori eradication before, are known to be allergic to any drug used in this trial, are pregnant, or refuse to participate in the trial for any reason will be excluded. We then allocate these patients into two groups randomly - one group receiving vonoprazan-based dual therapy with high-dose amoxicillin (vonoprazan 20 mg + amoxicillin 1000 mg twice daily for fourteen days) and the other receiving extended sequential therapy (lansoprazole 30mg plus amoxicillin 1000mg twice daily for 7 days, followed by lansoprazole 30mg, clarithromycin 500mg, and metronidzole 500mg twice daily for an additional 7 days). Eradication success was evaluated by 13C-urea breath test at least 4 weeks after treatment. Outcome analysis: The study will be designed as a non-inferiority trial. We anticipate that the two regimens will have comparable efficacy. Besides, we'll also design a questionnaire to evaluate the adverse effects, whether they took the drugs in the right way, and patient's satisfaction of the drug regimen. The vonoprazan dual therapy with high-dose amoxicillin will be anticipated to have fewer adverse effects, better compliance, and better satisfaction.
The goal of this clinical trial is to compare the standard triple therapy with Bismuth quadruple therapy in children infected with Helicobacter pylori. The main questions to answer are: - the safety - the efficacy of the quadruple protocol with Bismuth subcitrate Participants will be randomised in 7-days eradication therapy group and 14-days eradication control group.
The goal of this clinical trial is to compare the efficacy of two different therapeutic regimen for the treatment of Helicobacter pylori infected dyspeptic patients. The aim is - 1. To identify the percentage of H. pylori infection among dyspeptic patients 2. To compare the efficacy of amoxicillin-esomeprazole high dose dual therapy with levofloxacin containing triple therapy for the eradication of Helicobacter pylori. Participants will be screened on the basis of two different test (stool antigen test & endoscopy with rapid urease test) to detect H. pylori infection. Who are positive on both tests will be finally enrolled in the study and randomized into two groups . one group will receive amoxicillin & esomeprazole for 14 days in higher dose. The other group will receive amoxicillin, levofloxacin & esomeprazole for 14 days in usual dose. Dyspeptic symptoms will be recorded before & after treatment. Side effects of drugs will also be recorded. Finally 1 month after completion of treatment , H.pylori status will be cheeked by stool antigen test and results will be compared between two groups.
Helicobacter pylori (H. pylori) infection is a common global infectious disease of the gastrointestinal tract. Helicobacter pylori eradication can effectively prevent the development of gastric cancer.The researchers collect H.pylori-positive patients who need native therapy. The subjects were randomized to receive7 days and 14 days of bismuth quadruple eradication therapy. 6-8 weeks after treatment, the subjects will re-take the 13C-urea breath test. Calculate the eradication rates, adverse reaction rates and patient compliance of each group.
The aim of this study is to: • Evaluation of efficacy and safety of adding black seed oil with vonoprazan triple therapy ( vonoprazan ,clarithromycin and amoxicillin ) in eradication of Helicobacter pylori infection and this will be done through evaluation of: A. Efficacy by: 1. determination of successful eradication,which will be considered to be achieved on the basis of a negative stool antigen test four weeks after the end of treatment using Stool Ag test 2. The effect of N. Sativa on: I. Oxidative stress by measuring MDA II. Inflammation by measuring IL1B as inflammatory markers B. Safety will be done through: Monitoring of expected treatment related adverse effects (black seed oil and vonoprazan triple therapy ) will be done through the whole study period. C. Symptoms evaluation using the Gastrointestinal symptom rating scale D. Assessment of patient's quality of life using SF36 questionnaire
This exploratory study is designed to compare safety and efficacy between a Tegoprazan dose-specific standard triple therapy and Lansoprazole standard triple therapy in H. pylori positive patients.
Gastric cancer remains a global health problem, and Chile has one of the highest GC mortality rates in the region. Helicobacter pylori (H. pylori) infection is ubiquitous in Chilean adults, and it constitutes the main cause of GC worldwide. A long-term process occurs from premalignant lesions to carcinoma. H. pylori eradication during early stages of disease significantly impacts outcomes, favoring survival, disease reversal and molecular changes, which supports a "screen and treat" strategy in asymptomatic populations in areas with intermediate-to-high GC prevalence. The Investigators' previous research has shown that H. pylori infection is acquired in early childhood with low rates of spontaneous eradication. A pilot treatment study in a subset of school-aged asymptomatic children showed a high rate of successful eradication (>95%), good tolerance, and was associated with a decrease in serum biomarkers of gastric damage (pepsinogen I and II). Based on the results of these studies, the Investigators propose to advance towards the next stage of this research process: a "screen and treat" strategy. The current trial starts with a Screening phase testing 1000 asymptomatic adolescents 14-18 years of age from 3 cities of Chile (Colina, Temuco and Coyhaique), to find a total of 200-250 persistently-infected participants. Persistently-infected adolescents will be included in a Second phase of this trial: A randomized, case-control, non-blinded study to either receive antimicrobial treatment targeting H. pylori eradication (cases) or no treatment (controls). A subset of 60 non-infected adolescents will be followed-up in matched times. This aims to provide evidence on the effect of treatment on clinical outcomes and serum biomarkers related to gastric damage, as well as composition and antimicrobial resistance of gut microbiota. The Investigators expect that eradication therapy will be successful in >90% of persistently infected adolescents, with reinfection rates not surpassing 15% in a 2-3 year period, and to be associated with a decrease in clinical findings indicative of gastric disease, and a decrease in serum biomarker indicative of "gastric damage".
