NCT02164409
This is a research study for patients who currently have or previously had an H. pylori infection or who have gastric or esophageal cancer and who plan to undergo an endoscopy as part of their care. The purpose of this study is to find out how and why H. pylori infections can cause progression to gastric cancer and if it's possible for intervention prior to this progression.
NCT01506986
HEAT (Helicobacter Eradication Aspirin Trial) is a large simple double-blind placebo controlled outcomes study of Helicobacter pylori (H. pylori) eradication to prevent ulcer bleeding in aspirin users. It will be run by the University of Nottingham, with recruiting centres across the UK. This trial is funded by the National Institute of Health Research Health Technology Assessment (NIHR HTA) Programme. Aspirin use is widespread and increasing in elderly patients. The main hazard is gastrointestinal bleeding, which may be increasing because of increasing aspirin use. This trial is based on evidence that peptic ulcer bleeding in aspirin users occurs predominantly in H. pylori positive people. Patients will be identified by their GPs, then asked to attend an appointment with a Research Nurse to consent to the trial and take a H. pylori breath test. Those with a positive result will be randomised to receive a one week course of either eradication treatment or placebo. No follow-up visits are required, but instead information will be extracted from the patients' electronic medical record using the MiQuest search tool. The trial will continue until 87 adjudicated events (hospitalisation because of definite or probable peptic ulcer bleeding) have occurred, which would occur after a mean 2.5 patient years of follow-up, if trial assumptions are correct.
NCT02553083
The investigators will performed a large-scale multi center trial to compare the efficacy of a high-dose dual therapy (HDDT) with that of standard therapies in treatment-naive (n = 300) patients with Hp infection. Consecutive symptomatic patients will be recruited in Israel and Spain when tested positive to Hp with serology and 13C urea breath test (13C-UBT) due to symptoms. Patients with gastric cancer, MALT lymphoma, and younger than 18 or older than 80 years old will be excluded. All patients will be naive to eradication therapy and will be randomized into one of three groups: Group 1: Nexium 40 mg and amoxicillin 1.5 gr twice daily for 14 days Group 2: Nexium 40 mg and doxycycline 200 mg twice a day Group 3: Triple therapy of Nexium 20 mg, clarythromycin 500 mg, and amoxicillin 1gr twice a day for 10 days (regular accepted treatment). All treatments will be stopped for a month and then 13CUBT will be repeated. The primary aim of the study is to assess eradication success, intentioned to treat and per protocol in the three treatment regimens. The secondary aim of the study is to assess the safety of high dose amoxicillin and doxycycline.

Epidemiology of Helicobacter Pylori Infection Among Shanghai Children.
NCT01902589
Helicobacter Pylori (HP) is one of the most common pathogens in humans. This infection can present in children with abdominal pain, vomiting and iron deficiency. The treatment is usually empiric and includes antibiotic treatment usually Amoxycillin and Clarithromycin or Metronidazole. Between 40 to 70 % of the pathogens are resistant to those drugs, and it is important to characterize the specific sensitivity of the pathogens in any specific area and in pediatric population. The aims of this study is to assess the sensitivity of HP in pediatric population in Northern Israel.
NCT01623154
The purpose of this study is to compare between the POCone® to the UBiT®-IR300 in measuring 13CO2/12CO2 ratio in breath samples when used together with the BreathTek® UBT (urea breath test) Kit and the pUHR-CA web-based software program in identifying H. pylori infection in pediatric subjects.
