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.
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.
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.
Helicobacter pylori (H. pylori) infection has been associated with a development of atrophic gastritis and intestinal metaplasia. H. pylori related atrophic gastritis and intestinal metaplasia have been regarded as pre-malignant lesion. However, the role of H. pylori eradication treatment in the reversibility of atrophic gastritis and intestinal metaplasia has not been clearly defined. The aim of the present study was to investigate the relationship between H. pylori eradication and the reversibility of atrophic gastritis and intestinal metaplasia in Korean patients.
Reverse hybrid therapy achieves a higher eradication rate than concomitant therapy remains unanswered.
Asia Pacific Consensus states that levofloxacin-based triple therapy as an alternative second-line therapy after Helicobacter pylori (H. pylori) eradication failure when bismuth salts are not available. The investigators compare the efficacies of 10-day levofloxacin-based sequential therapy and 10-day triple therapy in the treatment for patients after failure of standard triple therapy and to determine what clinical and bacterial factors influencing the efficacy of salvage regimens.
In this randomized controlled trial, we investigate the effect of 10-day bismuth quadruple therapy in comparison with that of 7-day PPI-based standard triple as 1st line treatment for H. pylori.
Reverse hybrid therapy achieves a higher eradication rate than bismuth quadruple therapy remained unanswered.
