Filter by:The accurate diagnosis of H. pylori infection is an important step for establishing the strategy for gastric cancer prevention. During endoscopy, rapid urease test (RUT) is the first of biopsy-based H. pylori tests. Despite indirect test for H. pylori detection, RUT shows rapid result with good sensitivity and specificity. Several study reported that H. pylori density was related to positive reaction time of RUT. However, there was no study comparing the positive reaction times of RUT according to biopsy site, degree of gastric atrophy, and intestinal metaplasia.
With markedly increased antibiotic resistance and unsatisfactory efficacies of common empiric eradication regimens in the mainland of China, tailored therapy may be the best choice to achieve good efficacy. This study compared the eradication rates, safety, and compliance of antibiotic sensitivity-based tailored therapy compared with empiric bismuth quadruple therapy in the naive patients with Helicobacter pylori infection.
Helicobacter pylori infects ~ 50% of the world's population and a quarter of the European population. H. pylori is responsible for a large proportion of gastric and duodenal ulcers and gastritis. Chronic infection with H. pylori is a risk factor for the development of stomach cancer and MALT (mucosa-associated lymphoid tissue) Lymphoma. The prospects of success for an antimicrobial eradication therapy is drastically reduced by the significant increase in antibiotic resistance in Austrian H. pylori isolates. The currently available data were obtained however from narrowly defined geographical regions and the clinical routine without information on patient selection. We suspect a considerable geographical variability of resistance patterns and a clinical bias for a preferential investigation of patients with unsuccessful, empirical eradication therapy. The objective of the proposed study is therefore an Austria-wide collection of data on H. pylori resistance in a prospective clinical study. The data thus collected will enable a significant improvement in current treatment recommendations.
Clinical Study to Confirm Safety and Accuracy in Detection of H. pylori with 13C-Urea Breath Test using the BreathID® Hp and BreathID® Hp Lab Systems in the Pediatric Population
Gastric cancer is one of the leading causes of cancer-related deaths worldwide. In Taiwan, there are around 3800 fresh cases annually, with about 5% of total cancers cases. Gastric cancer development is known to follow a multistate process from non-atrophic gastritis, atrophic gastritis, intestinal metaplasia, dysplasia, and carcinoma; H. pylori infection plays the key role of this carcinogenic process. Although H. pylori eradication would result in a marked gastric cancer reduction, treatment success using standard regimens has become more difficult in recent years, and increased antibiotic resistance is considered the most important reason for decreased treatment efficacy. As no specific new medications have been introduced in recent years, novel treatment regimens have been created using different combinations, durations and sequences of available medications. The addition of bismuth improved the cure rates despite a high prevalence of resistance, and resistance of H. pylori to bismuth has not been reported. Bismuth absorption is not required for efficacy in H. pylori treatment regimens, suggesting a local mechanism of action. The mechanisms of bismuth with responsible for rapid destruction of H. pylori within the stomach remain unclear. Knowledge of the mechanism of action of bismuth compounds against H. pylori would be beneficial in the development of improved treatment regimens in this era of declining eradication success rates. We conduct the pilot study to evaluate the bacteria fragments of H. pylori in specimen through electron microscopy after bismuth therapy and provide insight into the mechanism of action of pH on bismuth therapy. We also help to develop optimal H. pylori therapeutic strategies.
Doxycycline- and Furazolidone-containing Quadruple Regimen can be a successful rescue treatment for Helicobacter pylori Infection patients after Failure of several therapy. It is superior of tailored therapy as rescue treatment for helicobacter pylori Infection after failure of several therapy.
Patients who test Helicobacter pylori positive, are treated with antibiotics. However, due to a number of factors (such as unknown treatment compliance, no standardized follow-up, ...), a relative low eradication-percentage was reported. Therefore, the investigators want to measure the anticipated improvement in eradication-percentage due to the standardized treatment schedules (1st line, 2nd line and further) and the optimized communication with the general practitioner and patients.
To evaluate the efficacy and safety of Traditional Chinese Medicine (TCM) decoction and powder combined with standard triple therapy on improving eradication rate of Helicobacter Pylori (H. pylori).A multi-center randomized control clinical trial design was adopted in the trial.
Helicobacter pylori eradication (H. pylori) rates with clarithromycin-based triple therapy are declining, and an alternative strategy is needed urgently. The investigators sought to compare the efficacy of pretreatment antimicrobial susceptibility-guided vs. clarithromycin-based triple therapy vs. concomitant therapy for H. pylori eradication in a region with high rates of multiple drug resistance.
Standard triple therapy including a proton pump inhibitor (PPI) and clarithromycin with either amoxicillin or metronidazole are no longer recommended as empirical first-line therapy to treat Helicobacter pylori infection because of high antibiotic resistance. It is unknown whether the addition of bismuth overcome antibiotic resistance. This study is designed to evaluate the efficacy and safety of the addition of bismuth to standard triple therapy for H. pylori first-line eradication.
