Helicobacter pylori infection is associated with several gastric diseases, including gastritis, peptic and duodenal ulcers, gastric carcinoma and MALToma. In 1994, the WHO classified the organism as a type 1 carcinogen. In order to eradicate H. pylori, at least two antibiotics and a proton pump inhibitor are used as a standard therapy regimen. Emerging antibiotic resistance to metronidazole or clarithromycin, however, has made successful treatment of infection progressively more difficult, with the success rate of standard triple therapy now at 70%, well below the 80% required for treatment of infectious diseases. Therefore, new treatment regimen is required for successful H. pylori eradication. On the other hands, many in vitro studies revealed that bacterial carbonic anhydrase in H. pylori has an important role for surviving of H. pylori in the stomach. It was demonstrated that mutation of carbonic anhydrase affected survival of H. pylori. The investigators therefore expected that administration of carbonic anhydrase inhibitor (acetazolamide) with standard H. pylori eradication regimen would increase the eradication rate. Here, the investigators aim to evaluate the efficacy of standard triple regimen plus acetazolamide for H. pylori eradication.
Parts of patients are diagnosed as H. pylori -negative before ER, whereas the specimens become H. pylori-positive after ER, which may have a role in the recurrence of EGC. Our study aims to determine the difference in H. pylori infection rate of EGC patients before and after ER , and discuss the causes leading to the difference, which can provide references for improving the diagnostic accuracy of H. pylori infection and reducing EGC's recurrence rate.
Helicobator pylori (H. pylori) is a bacteria which survives in the lining of the stomach. An estimated 50% of the world's population is infected with H. pylori. Developing economies, such as in Southeast Asia, the Indian subcontinent and Latin America, have prevalence rates of as high as 90%. H. pylori infection often goes undiagnosed, as many sufferers do not experience any adverse symptoms. Infection with H. pylori is described as "not a disease in itself but a condition that affects the relative risk of developing various clinical disorders of the upper gastrointestinal tract.' Clinically relevant symptoms could include peptic ulcer, melena or secondary conditions such as iron deficiency anemia or vitamin B12 deficiency. There is evidence that probiotics can be beneficial for those with gastrointestinal diseases. Pylopass contains the probiotic strain Lactobacillus reuteri, which was selected for its anti-H. pylori characteristics and in clinical trials has shown to result in a reduction in urease breath test values in subjects with H. pylori. The objective of this study is to evaluate the ability of Pylopass to reduce H. pylori load in subjects who are H. pylori positive.
Over the years, it has become clear that the first-line triple therapy is losing efficacy worldwide. A capsule containing 3 agents (Pylera®) containing 125mg metronidazole, 140mg bismuth subcitrate potassium, and 125mg tetracycline was made available. The efficacy of the Pylera capsule was studied in a randomized control trial, in which a quadruple Pylera therapy (Pylera capsule and a PPI) was evaluated against the standard triple regimen. In the study, 3 three-in-one capsules were taken four times daily (after meals and at bedtime). Given the above, we aim at assessing the effectiveness of fewer pills per day of the Pylera capsule (3 Pylera capsules supplemented with the addition of amoxicillin and esomeprazole twice daily; sum of 10 pills/day for 10 days) in the eradication of H. pylori.
Background and Aims - H.pylori is a common human pathogen by which almost 50% of the world population is infected. According to the accepted guidelines, once H.pylori infection has been diagnosed,first line therapy with three drugs should be given. The triple treatment includes proton-pump-inhibitor-clarithromycin-amoxicillin but its eradication rate is only 70-80%. - Curcumin has many beneficial merits and it was also been demonstrated to be efficient in inhibition of H.pylori infection, in vitro.Therefore we aim to investigate whether addition of Curcumin to the standard triple therapy will increase the eradication rate of H.pylori infection. Methods - 150 consecutive patients that will undergo esophagogastroscopy in our Gastroenterology department and will be positive for H.pylori according to urease test and then by gastric biopsy, will be included. The patients will be randomized to two different treatments, according to binomial distribution. 75 patients will be treated with the standard triple therapy for 10 days and the other 75, will be treated for 10 days, with triple therapy combined with Curcumin that will be given three times a day. - During the treatment the patients will complete an adverse effect's questionnaires. 6 weeks after the completion of the treatment the patients will undergo urea breath test to confirm eradication. Patients will be asked to avoid antibiotics, bismuth compounds or proton-pump-inhibitor until the second urea-breath-test. - We will compare the eradication rate and the adverse effects between the two groups by using SPSS
The aim of the study is to establish efficacy and safety of Normia® probiotic, used as an add-on therapy in treatment of H. Pylori infection with the standard triple therapy approach. The primary objective in the study is determination of efficacy of Normia® probiotic as a supportive therapy in achieving a higher percentage of eradication of H. Pylori. The secondary objectives are to assess: - Safety profile of Normia® probiotic in everyday use, e.g. reduction in number of side-effects and better compliance to the eradication therapy - Safety and efficacy of Normia® probiotic in different demographic subgroups
Deep sea water (DSW) is characterized by high purity, low temperature, high nutrients and minerals and is obtained from the water flows 200 meters under the surface of the sea. The inhibition of H. pylori growth by DSW has been demonstrated in vitro study. However, up to now, there is few randomized control study to evaluate the anti-bacterial effects of ingesting DSW in patients with H. pylori infection. The aims of this study are: 1. to evaluate the anti-bacterial effects of ingesting DSW in patients with H. pylori infection; 2. to evaluate the patient adherence and adverse effects of ingesting DSW.
The purpose of this study is to investigate the trend of eradication rates of first-line triple therapy for Helicobacter pylori in recent ten years and clinical factors that affect the eradication in Korean.
Whether non-bismuth quadruple therapy (concomitant therapy) is more effective than bismuth quadruple therapy or triple therapy for 14 days remains unknown. Therefore, we aim to compare the eradication rates and long term re-infection rates of quadruple therapy for 10 days versus non-bismuth quadruple therapy for 10 days vs. triple therapy for 14 days. Methods: This will be a multi-center, open labeled, randomized control trial Patients: H. pylori infected patients who have willingness to receive eradication therapy Testing for H. pylori infection Before First Line Ttreatment (1)Any two positive of rapid urease test, histology, serology and culture or a positive UBT will be considered as H. pylori infected After First Line Treatment: C13-Urea breath test will be used to assess the existence of H. pylori 6-8 weeks after first line therapy. Long term reinfection: C13- Urea breath test will be used to assess the recurrence of H. pylori 1 year after eradication therapy
