Filter by:Helicobacter pylori (H. pylori) gastritis is a common bacterial infection among the elderly population. H. pylori infection causes chronic progressive gastric inflammation, peptic ulcer disease and gastric cancer. Gastric cancer is a significant contributor of cancer-related mortality. The eradication of H. pylori reduces the incidence of gastric cancer. However, the efficacy of H. pylori eradication has decreased dramatically because of antibiotic resistance. This study aims to (i) compare the eradication rates of H. pylori by triple therapy with vonoprazan for the treatment of H. pylori gastritis) (TTV regimen), with triple therapy with conventional proton pump inhibitor (PPI) (TTP regimen) in a multi-racial Asian cohort, (ii) evaluate the prevalence of antibiotic (klacid/amoxicillin/levofloxacin/tetracycline) resistance in H. pylori infected patients, and (iii) assess the safety of the TTV regimen. Diagnosed H. pylori-infected patients (n=252) will be enrolled and randomized 1:1 to TTV or TTP regimen. Gastric biopsies will be cultured and antibiotic sensitivity evaluated using E-test/agar dilution method. The safety of TTV regimen will be assessed using adverse effect questionnaire. This study may potentially impact on prescribing policies and management of H. pylori infections for improved therapeutic outcome.
This study aims at evaluating efficacy Clostridum Butyricum Capsule and Bacillus Coagulans Tablets in H. pylori eradication. It is hypothesized that Clostridum Butyricum Capsule , Bacillus Coagulans Tablets monotherapy or Clostridum Butyricum Capsule plus Bacillus Coagulans may have some positive effect on H. pylori eradication.
Mental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.
Research purpose To elucidate the effect mechanism and clinical effective of weifuchun in the prevention and treatment of chronic atrophic gastritis and precancerous lesions of gastric cancer. From genes related to cell differentiation, proliferation, apoptosis, tumor invasion and metastasis, genes related to immune inflammation and immune escape and other possible aspects to elucidate the effective and mechanism of weifuchun's treatment on chronic atrophic gastritis, reversing precancerous lesions of gastric cancer.
The hypothesis and plan of the current study are: 1. One induction phase of high dose PPI before eradication will increase intragastric pH and induce H. pylori into an active replicative status. Active replicative status will enhance the bactericidal effect of amoxicillin. Rabeprazole (20 mg) four times per day (qid) for 3 days will be used for induction in this study. 2. High dose PPI will provide adequate plasma concentration irrespective of the CYP2C19 genotype of the population. Here rabeprazole (20 mg) qid will be applied as high dose PPI. 3. High frequent amoxicillin usage (500 mg, qid) will maintain plasma concentration above the MIC. Amoxicillin (500 mg) qid will be described for total 14 days. 4. In the rescue therapy, add levofloxacin on high dose dual therapy will increase the eradication rate than single high dose dual therapy. A combination of levofloxacin and high dose dual therapy will also have a better eradication rate than the common used levofloxacin based triple therapy.
40 participants with Eosinophilic Gastritis 12-70 years of age will be randomly assigned with dupilumab or placebo subcutaneous injections every two weeks for a total of 12 weeks. Study subjects who complete the 12-week treatment phase, may continue into an open label extension study, where dupilumab will be administered every two weeks for a total of 24 weeks.
This is a Phase 2, open-label, extension study to assess the safety and tolerability of AK002, given monthly for up to 26 doses.
Functional dyspepsia (FD) is a common functional gastrointestinal disorder characterized by upper abdominal discomfort/pain and/or symptoms of meal-related fullness/satiety. There is currently no definitive therapy that is beneficial for all FD patients. Accumulating evidence suggests efficacy of tricyclic antidepressants (TCAs) in FD. However, no firm conclusion can be drawn currently due to the relatively small amount of studies and large heterogeneity between studies. In addition, TCAs are often associated with side effects, which occur early after initiation of therapy preceding the therapeutic effect and often result in discontinuation of the therapy. These side effects are related to drug metabolism, which depend on polymorphisms of the cytochrome P (CYP) enzyme system. It is therefore hypothesized that pre-treatment assessment of CYP genotype and subsequent exclusion of abnormal metabolizers limits the occurrence of side-effects and as such improves compliance and efficacy.
This study aims at evaluating efficacy and safety of berberine- amoxicillin containing quadruple therapy(berberine, amoxicillin, esomeprazole and bismuth) versus tetracycline-furazolidone quadruple therapy (tetracycline, furazolidone, esomeprazole and bismuth) in H. pylori rescue therapy. It is hypothesized that berberine-amoxicillin containing quadruple therapy is non-inferior to tetracycline-furazolidone quadruple therapy. Patients with confirmed failure of H. pylori eradication will be randomized to one of the treatments described above. 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.
