Active clinical trials for "Helicobacter Infections"

This study aims to investigate eradication rate, drug compliance, and adverse events in patients with confirmed Helicobacter pylori infection between tegoprazan, bismuth, metronidazole, and tetracycline for 14 days (TBMT) and PPI, bismuth, metronidazole, and tetracycline for 14 days (LBMT)

The treatment of helicobacter pylori is very important. The routine treatment is quadruple therapy. In recent years, double therapy has appeared and the curative effect is fair. However, antacid generally uses proton pump inhibitor. The proton pump inhibitor needs double dose to achieve good antacid curative effect. The effect of Tegoprazan used for inhibiting gastric acid is better than proton pump inhibitor. At present, some studies use Tegoprazan instead of common proton pump inhibitor, but almost all use double dose of Tegoprazan. In the previous study, we found that the effect of double dose of proton pump inhibitor can be achieved with 50mg QD of Tegoprazan. Therefore, in this study, 50mg QD of Tegoprazan was used to replace the double dose of proton pump inhibitor to observe the antibacterial effect of Tegoprazan on Helicobacter pylori.

Helicobacter pylori (H. pylori) is a gram-negative flagellated bacterium that inhabits the gastric environment of 60.3% of the world population, and its prevalence is particularly high in countries with inferior socioeconomic conditions, exceeding 80% in some regions of the globe , This phenomenon occurs among other reasons, due to the unsatisfactory basic sanitation and high people aggregations observed in many under developed nations, scenarios that favour the oral-oral and fecal-oral transmissions of H.pylori.Another possible transmission route of this pathogen is the sexual route. Several studies have shown that the colonization of H.pylori could be negatively and positively associated with the induction and progression of several diseases .It has been reported to be linked to gastric and duodenal ulcer, gastric carcinoma, and gastric mucosa-associated lymphoid tissue (MALT) lymphoma and gastritis ,A positive association also reported between H.pylori infection and oesophageal cancer. Moreover, evidence is also available on the positive association between H.pylori and non gastrointestinal diseases such as diabetes mellitus , coronary artery disease , and anaemia. Abdominal pain and discomfort, nausea, burping, and loss of appetite are common symptoms of H.pylori infection. Other symptoms include, bloating, weight loss, and heart burn. Several approaches are used in the detection of H. pylori. Both the invasive and the non-invasive methods are employed in the detection of H. pylori in a patient. Many factors, however, influence choices in the method of diagnosis: availability of diagnostic instruments/materials, sampling population, and competency and experience of the physicians/clinicians . Invasive methods include endoscopic evaluation, histology, rapid urease test (RUT), and bacterial culture. Non-invasive methods include urea breath test (UBT), stool antigen test (SAT), serology, and molecular diagnostic approaches .Endoscopy is an accurate test for diagnosing the infection as well as the inflammation. Endoscopy also allows the determination of the severity of gastritis with biopsies as well as the presence of ulcers, MALT lymphoma and cancer. Real-time endoscopy along with conventional white light imaging (WLI)and image enhanced endoscopic (IEE)techniques, such as narrow-band imaging (NBI), linked color imaging (LCI) and blue laser imaging (BLI), appear to have important roles in clinical practice to identify H. pyloriinfected status . Another endoscopic technique is i-scan digital chromoendoscopy, which is a digital contrast method that enhances minute mucosal structures and subtle changes in color . The overall diagnostic accuracy of i-scan is 97% compared to 78% for WLI .

The purpose of this study is to assess the safety and efficacy of Lactobacillus plantarum, Bacillus coagulans and Lactobacillus plantarum + Bacillus coagulans for eradication of Helicobacter Pylori, as well as the efficacy of Lactobacillus plantarum and Bacillus coagulans on side-effect caused by Helicobacter Pylori.

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: 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 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

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.

Helicobacter pylori affects the gut microbiome in ways that are only partially understood. In which patients H. pylori causes severe disease and in whom it merely colonizes, possibly even with beneficial effects, is not understood. The investigators are pursuing the hypothesis that changes in the gut microbiome that can be easily measured in stool have such predictive value.

The purpose of this study is to evaluate efficacy of a 14-day concomitant therapy for the third-line treatment of Helicobacter pylori infection, and whether it is safe while maintaining an ideal eradication rates.

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.

This study is a prospective randomized case-control study. Six hundred patients who were firstly diagnosed as Helicobacter pylori infection will be selected, and then randomly assigned into case group and control group. Patients in control group take bismuth quadruplicate for 14 days. Patients in case group take Ban xia xie xin Decoction and bismuth agent quadruple for 14 days. Exhalation test or stool Helicobacter pylori antigen detection were used to assess the eradication rate of Helicobacter pylori 30 days (the 45th day) after treatment; Adverse reactions were evaluated on the first day (15th day) and the 30th day (45th day) after treatment. The eradication rate of Helicobacter pylori and the adverse drug reactions during the medication will be evaluated. The effect of Ban xia xie xin Decoction and bismuth quadruple based on furazolidone on the eradication of helicobacter pylori infection will be explored.
