Filter by:Both hybrid and high-dose dual therapies developed by the scholars from Taiwan can achieve a high eradication rate for clarithromycin-resistant strains, and have a great potential to replace bismuth quadruple therapy in the treatment of H. pylori infection. This study aims to better understand the potential of both hybrid and igh-dose dual therapies in the treatment of H. pylori infection. .
The researchers collect treatment-naive H.pylori-positive patients from the outpatient clinic. The subjects were randomized to receive a 10-day or 14-day course of 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, patient compliance and cost-effectiveness index of each group.
Era of COVID-19 and the related panic lead to widely spread antibiotics misuse especially for azithromycin. Cross sensitivity between azithromycin and clarithromycin can impact success rates of H. pylori treatment regimens.(1) Here we aim to explore this point in Egyptian patients. Sample size Supposing the cure rate of clarithromycin-based regimen to levofloxacin based regimen is 69% versus 84.5% respectively. Using Medcalc, the minimal required sample size is 116 patients for each arm (type 1 error= 5%, type II error=20%). Each arm increased by 10% to compensate for drop-out. The sample size will be 135 for each arm. Study Arms: - Arm 1: The first group will receive (amoxicillin 1g/12 hrs, Clarithromycin 500 mg/12hrs, esomeprazole 40mg/12hrs) - Arm 2: The second group will receive (esomeprazole 40 mg/12hrs, levofloxacin 500 mg/24 hrs, and amoxicillin 1gm/12 hrs). - To confirm patient compliance, we will ask patients to bring their remaining medication and counted the rest of their pills. Patients with a compliance of <80% will be excluded from the study per protocol (PP) analysis.
The purpose of this study is to assess the efficacy and safety of berberine, amoxicillin and vonoprazan containing triple therapy in Helicobacter Pylori first-line eradication. It is hypothesized that berberine hydrochloride, amoxicillin and vonoprazan triple therapy is non-inferior to bismuth-containing quadruple therapy or vonoprazan -containing quadruple therapy. Patients diagnosed with H. pylori infection will be randomly divided into one of the above treatments. At week 6 follow-up visits, a urea breath test，rapid urease test or helicobacter pylori stool antigen test will be performed to confirm eradication.
As we know，Helicobacter pylori is closely related to many gastrointestinal diseases such as chronic gastritis, peptic ulcer disease,gastric carcinoma and gastric mucosa-associated lymphoid tissue lymphoma，as well as extra-digestive diseases such as urticaria and chronic obstructive pulmonary diseases and so on.The diagnosis of H. pylori infection is based on invasive methods requiring endoscopy and biopsy(e.g. histology, culture, rapid urease test, PCR) or on non-invasive methods (e.g. serology, 13C urea breath test, stool antigen test).Histology has the highest specificity among the others,and also allows us to determine the underlying disease and perform antibiotic sensitivity testing.Serological tests are widely available and more appropriate for epidemiological studies, their main weakness for clinical use is low specificity.The 13C urea breath test is the most accurate method in patients irrespective of age.Stool antigen testing,as a promising method, is easy to perform, and its accuracy may be improved by the use of monoclonal antibodies recently proposed for capturing H. pylori antigen in stool specimen.Sensitivity and specificity, usefulness,and limitation of tests should be considered for selection of detection methods of H. pylori. Our objective is to review the current methods that are used for the detection of H. pylori infection among patients with chronic atrophic gastritis.Except that,patients with Hp positive will be further treated with 10-day minocycline-based quadruple therapy,to observe the efficacy and safety of minocycline-based regimen for H.pylori eradication as a first-line therapy.
Helicobacter pylori can lead to a variety of digestive system diseases.The eradication of Helicobacter pylori plays an importment role for the treatment of gastrointestinal ulcer and prevention of gastric cancer .Compared with other countries and regions in the world, the infection rate of Helicobacter pylori in China can reach more than 50%. The non-standard diagnosis and treatment of Helicobacter pylori greatly reduces its eradication rate and increases its drug resistance.Therefore, it is very important to strengthen the standardization of diagnosis and treatment to improve the eradication rate. The purpose of this study is to investigate the diagnosis and treatment status of Helicobacter pylori among gastroenterologists in general hospitals in Shandong Province.It can help us to understand the actual situation of diagnosis and treatment of Helicobacter pylori in hospitals at all levels, and to provide targeted diagnosis and treatment training for doctors.
RCT for comparison of Standard Triple therapy (Omeprazole+Amoxil+Clarithromycin) for H Pylori erradication with Vonoprazan+Amoxil dual therapy.
This study is planned to reveal the occurrence rate of H.pylori infection in ambulatory settings' patients in Russia and to compare the occurrence rates in different years in treatment-naïve and previously treated subjects.
Rifabutin has good chemical stability and low drug resistance rate in acidic gastric environment. Therefore, it is often used in combination with amoxicillin proton pump inhibitor for the rescue treatment of Helicobacter pylori. The purpose of this study was to evaluate the efficacy and safety of rifabutin-containing triple therapy versus classical bismuth-containing quadruple therapy as rescue therapy for the eradication of refractory Helicobacter pylori
Helicobacter pylori (H. pylori) is a spiral shaped, microaerophilic, gram negative bacterium. The organism resides in the acid and mucous layer of the human gastric mucosa, adheres to and colonizes the mucosal surface of the stomach and the mucosal epithelium with gastric metaplasia of duodenal bulb. Many studies have shown that H. pylori is an important causal factor of chronic gastritis, peptic ulcer disease, gastric cancer and gastric lymphoma. Endoscopic examination is indicated to confirm the above diagnosis for patient with H. pylori infection. The eradication rate of standard triple therapy has fallen below 80% in many countries due to the worldwide increasing prevalence of antibiotic resistant strains. This is related to the special gastric milieu of H. pylori, which leads to a more difficult and complicated treatment for achieving a successful eradication rate than other bacteria. Several strategies have been proposed to increase the eradication rate in the first line therapy or as a rescue therapy. However, these rescue therapies will increase the side effects and costs of treatment, decrease the compliance of patients and increase the rate of worldwide antibiotic resistance steadily. The WHO has listed H. Pylori as one of 12 antibiotic-resistant bacteria that have the greatest threat to human health in Feb. 2017. Our previous studies suggested that the administration of single -dose therapeutic agents can achieve the eradication of H. pylori immediately while conducting the endoscopic examination. The eradication rate of intraluminal therapy for H. pylori infection (ILTHPI) is 53.7% (51/95), and control the intragastric pH above 4 prior to the ILTHPI can even reach a 72.0%(36/50) eradication rate of H. pylori. According to the recent Taiwan consensus for the treatment of H. pylori in 2017, the first line therapeutic regiment of H. pylori containing Amoxicillin, Clarithromycin, and Metronidazole if the rate of Clarithromycin resistance is below 15%, while the first line therapeutic regiment of H. pylori containing tetracycline, metronidazole, and bismuth subcitrate if the rate of Clarithromycin resistance is above 15%. We aimed to evaluate and compare the efficacy of medicament containing Tetracycline, Metronidazole, and Bismuth versus Amoxicillin, Metronidazole, and Clarithromycin for the Intraluminal therapy of Helicobacter pylori infection.
