NCT06977841
Current first-line Helicobacter pylori eradication protocols involve multidrug regimens comprising a proton pump inhibitor (PPI) or bismuth agent combined with dual antibiotics (e.g., clarithromycin, amoxicillin, quinolones, furazolidone, nitroimidazoles, or tetracycline) administered for 7-14 days. In China, the bismuth-containing quadruple therapy (BQT) remains the standard first-line treatment for H. pylori infection. However, BQT implementation is challenged by polypharmacy burdens, substantial adverse events, and suboptimal treatment adherence. Emerging evidence suggests that simplified dual therapies pairing acid suppressants (PPIs or potassium-competitive acid blockers \[P-CABs\]) with high-dose amoxicillin achieve comparable eradication rates to BQT while demonstrating superior tolerability and adherence profiles. Notably, the comparative efficacy of tetracycline-based versus amoxicillin-based dual regimens remains unexamined in controlled clinical trials. Our preliminary investigations established that optimized PPI-amoxicillin dual therapy achieves \>90% eradication rates in treatment-naïve populations. Building on these findings, this prospective randomized controlled trial will comparatively assess the effectiveness of tegoprazan-a novel P-CAB exhibiting potent acid inhibition-when co-administered with either amoxicillin or tetracycline in H. pylori-positive adults. The investigation aims to establish an evidence framework for streamlining eradication protocols through pharmacodynamic optimization while mitigating antimicrobial resistance development.
NCT07408271
This clinical controlled study enrolled 73 H. pylori（Helicobacter Pylori ）-infected female participants, stratified into reproductive-age and menopausal cohorts, alongside 10 non-infected controls. Through integrated analysis of routine vaginal discharge parameters and longitudinal amplicon sequencing data of vaginal discharge, investigators analyzed the impact of H. pylori eradication therapy on vaginal microecology.
NCT05870397
Although Urea breath test has been commonly used to recheck the efficiency of Helicobacter pylori eradication, there has been no randomized trials comparing the accuracy of Urea breath test results at different times after eradication. The investigators aim to assess the accuracy and influence factors of post-therapy test at different times and follow up the cut off samples to optimize the best time to recheck.
NCT05186662
we conducted a retrospective study to compare the efficacy of WeChat-based patient education and conventional patient education in the management of Helicobacter pylori eradication.
NCT05191888
1. Test for Helicobacter pylori. The test items include urease test, histology, bacterial culture, serology, and urea breath test. At least two positive results can be used to confirm the diagnosis. 2. To ensure that the research results are not artificially distorted, this trial is a randomized study. Random allocation (which means that the subjects will use the "random number table generated by a computer similar to the lottery" to determine the treatment group) accept one of the following schemes (1:1:1).
NCT03924375
Helicobacter pylori has been recognized as a major pathogen in gastric carcinogenesis. Current guidelines recommend the H. pylori "test-and-treat" strategy for the purpose of primary and secondary gastric cancer prevention. Considering the "point of no return" theory, however, H. pylori eradication cannot reduce the risk of gastric cancer in subjects with gastric atrophy and intestinal metaplasia. The intragastric hypoacidic environment is associated with the risk of intestinal-type gastric cancer development. Recently, the secretory ability of the stomach can be measured using the serum pepsinogen (PG) assay.
NCT02776371
Helicobacter pylori (H. pylori) infects more than 50% of the population in the world(1), especially 47-66% in China.
NCT02833623
Helicobacter pylori (H. pylori) is a pathogen that infects more than 50% of the human population, resulting in high healthcare costs worldwide. However, H. pylori eradication rate is low nowadays and patients's compliance is one of the most important effective factors.
