NCT ID: NCT06412588 Not yet recruiting - Clinical trials for Helicobacter Pylori Infection

Dual Therapy With Vonoprazan Plus Amoxicillin or Doxycycline Versus Bismuth Quadruple Therapy for Helicobacter Pylori Eradication:A Prospective, Multicenter, Open-label Randomized Controlled Study.

Start date: May 2024
Phase: N/A
Study type: Interventional

It is planned to select Hp infection patients in a number of tertiary hospitals in Jiangsu and randomly divide them into three groups: group A is the classic group, receiving Vonoprazan 20mg, bid + amoxicillin 1.0g, bid + doxycycline 0.1g, bid + colloidal pectin bismuth 0.3g, bid and group C are double groups, respectively, receiving standard dose amoxicillin (1.0 g, bid) combined with vonorrasan dual regimen and doxycycline (0.1g, bid) combined with Vonoprazan dual regimen, the treatment course of the three groups was 14 days, and the oral dose of Vonoprazan was 20mg, bid, the eradication rate, adverse reactions, compliance and other aspects of the three groups were compared, In order to obtain a safe, efficient, economical and convenient Hp eradication program with a wider range of applications.

NCT ID: NCT06351891 Not yet recruiting - Clinical trials for Helicobacter Pylori Infection

Efficacy and Safety of Bismuth Quadruple Therapy Containing Cefuroxime and Tetracycline as First-line Therapy for Eradicating Helicobacter Pylori in Patients Allergic to Penicillin

Start date: April 2024
Phase: Phase 4
Study type: Interventional

The researchers collected untreated H. pylori positive patients from outpatient clinics. Subjects were randomly assigned to receive either 14 days of bismuth quadruple therapy with cefuroxime and tetracycline or 14 days of bismuth quadruple therapy with cefuroxime and levofloxacin for Helicobacter pylori eradication. After 6 weeks of treatment, subjects underwent another 13C urea breath test. Eradication rates, adverse reaction rates and patient compliance were calculated.

NCT ID: NCT06340724 Not yet recruiting - Clinical trials for Helicobacter Pylori Infection

Banxiaxiexin Decoction Combined With Vonoprazan-Amoxicillin Dual Therapy in H.Pylori Eradication

Start date: March 2024
Phase: Early Phase 1
Study type: Interventional

Vonoprazan and high-dose amoxicillin dual therapy was used as a control group to evaluate the clinical effiency and safety of Banxiaxiexin decoction combined with vonoprazan and high-dose amoxicillin dual therapy in the treatment of helicobacter pylori infection complicated with functional dyspepsia,through a randomized controlled trail.

NCT ID: NCT06273384 Not yet recruiting - Clinical trials for Helicobacter Pylori Infection

Diagnostic Performance of CIM for Helicobacter Pylori Infection in Patients With Peptic Ulcer Bleeding

CIM
Start date: March 1, 2024
Phase:
Study type: Observational

The goal of this cross-sectional study is to evaluate the efficacy of current infection marker (CIM) method for H. pylori detection. The main questions it aims to answer are: - To evaluate the efficacy of CIM method for H. pylori detection compared to rapid urease test(RUT), histopathology, polymerase chain reaction (PCR), and urea breath test (UBT) in patients who presented with upper gastrointestinal hemorrhage from peptic ulcer, and their sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio, and negative likelihood ratio. - To evaluate the advantages of CIM method for H. pylori detection comparing to RUT, histopathology, PCR, and UBT in patients who presented with upper gastrointestinal hemorrhage from peptic ulcer as net reclassification index (NRI). - To study the associated factors in false negative value of H. pylori detection methods with CIM, RUT, histopathology, PCR, and UBT.

NCT ID: NCT06200779 Not yet recruiting - Clinical trials for Helicobacter Pylori Infection

Tailored vs. Empirical Helicobacter Pylori Infection Treatment

Start date: September 2024
Phase: Phase 4
Study type: Interventional

Helicobacter pylori (Hp) is a gram-negative bacterium that colonizes human gastric mucosa and is associated with chronic gastritis that can progress to severe complications such as peptic ulcer disease, gastric adenocarcinoma and gastric mucosa-associated lymphoid tissue lymphoma. More than half of the world's population is infected with H. pylori and Portugal is one of the countries with the highest Hp burden. All of infected patients should be treated, however, H. pylori treatment is challenged by the continuously rising antibiotic resistance which has reached alarming levels worldwide. For this reason, it is now well accepted that tailoring treatment of H. pylori infection based on systematic antimicrobial susceptibility testing is useful to avoid the increase of antibiotic resistance. Our aims are to determine prospectively the efficacy and safety of first-line H. pylori eradication treatment based on resistance profile (determined by molecular methods) vs. empirical bismuth quadruple therapy, to evaluate the accuracy of H. pylori detection by polymerase chain reaction (PCR) (vs. histopathological examination) and to estimate the prevalence of H. pylori infection and H. pylori resistance to clarithromycin and levofloxacin in Portugal. This prospective study will be the first national study to investigate the benefits of tailored H. pylori eradication treatment. The investigators expect that this project will be able to demonstrate the non-inferiority of susceptibility-guided treatment comparing with empirical therapy, and our results may change H. pylori treatment recommendations by systematically applying antibiotic susceptibility testing before prescribing eradication therapy.

NCT ID: NCT06065267 Not yet recruiting - Clinical trials for Helicobacter Pylori Infection

Levofloxacin Concomitant Versus Levofloxacin Sequential

Start date: January 2, 2024
Phase: Phase 4
Study type: Interventional

The goal of this trial is to determine the efficacy of levofloxacin based sequential treatment regimen or concomitant levofloxacin based regimens as empirical first-line therapy in the Syrian population

NCT ID: NCT06037122 Not yet recruiting - Clinical trials for Helicobacter Pylori Infection

Efficacy of Low-dose Vonoprazan for Helicobacter Pylori Eradication

Start date: September 2023
Phase:
Study type: Observational

The primary objective of this retrospective study was to assess the efficacy and safety of a bismuth quadruple regimen of a low-dose potassium-competitive acid blocker versus a standard-dose potassium-competitive acid blocker and a standard-dose proton pump inhibitor combined with amoxicillin and clarithromycin as the initial treatment of Helicobacter pylori infection.

NCT ID: NCT05726734 Not yet recruiting - Clinical trials for Helicobacter Pylori Infection

Vonoprazan-containing Triple Therapy Versus Empiric Bismuth Quadruple Therapy for First-line Helicobacter Pylori Treatment: a Randomized Clinical Trial

Start date: February 6, 2023
Phase: Phase 4
Study type: Interventional

Vonoprazan Amoxicillin and metronidazole based triple therapy had achieved a high cure rate in the rescue treatment of helicobacter pylori infection. This study aims to evaluate the efficacy and safety of the Vonoprazan, amoxicillin and metronidazole based triple therapy and the empiric bismuth quadruple therapy in the naive patients with Helicobacter pylori infection.

Effect of Probiotics on Eradication of Persistent H.Pylori Infection

Start date: January 1, 2023
Phase: N/A
Study type: Interventional

This study aims to investigate the possible safety and efficacy of probiotics (Bifidobacterium Infants, Enterococcus Feacium, and Lactobacillus Acidophilus) on the eradication rate of Helicobacter pylori and the incidence of adverse effects (AEs) of the concurrent rescue regimen in a patient with persistent H. Pylori infection.
