Filter by:This randomized controlled clinical trial will evaluate the efficacy and safety of proton pump inhibitor, bismuth, metronidazole, and either tetracycline or doxycycline for Helicobacter pylori rescue treatment. The completion of this trial will expand new therapy for the treatment of Helicobacter pylori.
Helicobacter pylori infection causes active peptic ulcer disease and related complications like bleeding and pyloric obstruction. Usually, clinicians tended to treat Helicobacter pylori infection after active peptic ulcer disease and related complicaitons getting healed, which spent time and money. This study is designed to evaluate the efficacy and safety of intravenous administration of metronidazole, levofloxacin and esomeprazole triple therapy in the treatment of Helicobacter pylori infection combined with peptic ulcer disease related complications.
People nowadays tend to have irregular diet and routine due to the stress at work. This condition may cause intestinal microflora imbalance, and in the long term may lead to constipation, diarrhea, gastroenteritis, gastric ulcer and other gastrointestinal diseases. Helicobacter pylori infection, which can trigger gastrointestinal inflammation and ulcer, is commonly treated by antibiotics. This treatment, however, can reduce the diversity of the intestinal microflora, causing diarrhea, flatulence and nausea. Clinical trials showed that probiotics and prebiotics supplementation could regulate gastrointestinal function, including alleviating constipation, ameliorating antibiotic-associated diarrhea and flatulence, enhancing the effect of H. pylori treatment, and restoring the balance of intestinal microflora. This Probiotics product is a supplement containing several types of probiotics and prebiotics which has been marketed for years. This project aims to observe the effectiveness of Probiotics product consumption by H. pylori-infected patients in relieving the gastrointestinal symptoms and restoring their intestinal microflora.
The aim of our study will be to assess in an open-label, multicenter, randomized controlled trial whether a tailored therapy guided by a non-invasive antibiotic susceptibility test on stool samples achieves higher Helicobacter eradication rates than an empiric antibiotic regimen. For this purpose, consecutive patients with dyspeptic symptoms, diagnosis of Helicobacter pylori infection and naïve to eradicating treatments will be allocated to either of the two intervention arms.
Dual-focus with narrow-band imaging (DF-NBI) is a novel technique to improve the quality of images of the irregular mucosal structures and microvessels of gastric neoplasms. The investigators compare this technique with conventional white light (WL) endoscopy to predict Helicobacter pylori infection.
The aim of this study is to Identify antibiotic resistance gene mutations in Helicobacter pylori (HP) and genetic diversity of drug metabolism for antibiotics and proton pump inhibitors (PPIs) in patients with HP infection using next-generation sequencing (NGS). The mutation of host/HP strain will be investigated by single NGS, and the eradication results according to genetic polymorphism of host/HP strain will be analyzed.
Helicobacter pylori (H. pylori), a bacteria transmitted from human to human through upper digestive tract as well as fecal-oral transmission, had infected more than half of people around the world. However, the quantity of H. pylori in oral cavity and its influence on oral microbiota remains to be unclear. The aim of the present study was to examine the effects of H. pylori infection as well as its eradication on oral microbiota.
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.
The investigators aimed to assess the effect of probiotic supplementation with Vigiis 101-LAB during H. pylori eradication therapy with 14-day sequential therapy in the reduction of adverse effects and the restoration of the dysbiosis.
Clarithromycin (CLA)、amoxicillin (AMO)、metronidazole (MET)、levofloxacin (LEV) and tetracycline (TET) are commonly used antibiotics for Helicobacter pylori (Hp) therapy. However, the efficacy of treatment for Helicobacter pylori infection has decreased due to increasing resistance to CLA, MET and LEV. Studies had reported that beside antibiotics resistance, other factors such as age, sex, underlying disease, etc. may also affect the treatment efficacy. In some cases, when the MIC values were beyond the breakpoint, H. pylori strains with lower MIC value had better eradication than the ones with higher MIC value. However, few study investigated the relationship between MIC values and treatment outcome. The investigators aimed to analyze the impact of influencing factors, especially minimal inhibitory concentration (MIC) value, on the efficacy of different treatment regimens.
