Filter by:Nowadays, the gold standard examinations for diagnosing H. pylori infection are histopathology and culture examination. However, those examinations take long preparation so they are not suitable to be applied in daily practice. In progress, another examination is being developed to detect urease enzyme from tissue biopsy. It is relatively faster in diagnosing H. Pylori infection. Some commercial urease tests which are available in Indonesia are Helicotec® and Pronto Dry®. This study aims to determine the effectivity of Helicotec® in diagnosing H. pylori infection. It is expected to be scientific evidence that can be used as the basis daily routine of urease test in diagnosing H. Pylori infection.
Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in humans. The prevalence of H. pylori is about 30~50% in the Western adult population. It is estimated that about 50% of people are infected with this bacterium in Taiwan. Many studies have shown that H. pylori is an important causal factor of chronic gastritis, peptic ulcer disease, gastric cancer and gastric lymphoma. The World Health Organization classified H. pylori as a Group 1 carcinogen in 1994. Endoscopic examination is indicated to confirm the above diagnosis for patient with H. pylori infection. Eradication of H. pylori infection reduces the risk of gastric cancer and recurrence of peptic ulcer disease. However, the eradication rate of clarithromycin-based triple therapy has been declining in recent years, probably related to the increasing resistant rate to clarithromycin. Several strategies have been proposed to overcome the declining eradication rate, including (1) extending the treatment duration of triple therapy to 14 days; (2) the use of bismuth quadruple therapy which contains bismuth, a proton pump inhibitor, and two antibiotics (usually metronidazole and tetracycline); (3) non-bismuth quadruple therapy (concomitant therapy) which contains a proton pump inhibitor and three antibiotics (usually amoxicillin, metronidazole, and clarithromycin); (4) sequential therapy which contains a proton pump inhibitor (PPI) plus amoxicillin for five days, followed by a PPI plus clarithromycin and tinidazole for another five days. The investigators aim to evaluate the efficacy of Metronidazole powder in the Intraluminal therapy for Helicobacter pylori infection while an endoscopic examination is performed.

The triple treatment including Proton pump inhibitor (PPI) -clarithromycin and amoxicillin or metronidazole was proposed 30 years ago at the first Maastricht conference to treat helicobacter pylori (H. pylori) infection and since that time, it has become the universal and standard treatment for helicobacter pylori. However, the efficacy of this triple regimen has been seriously challenged, and they are gradually becoming ineffective
Clarithromycin-resistant H. pylori is the main cause of H. pylori eradication failure. Tailored therapy on the basis of detection of a clarithromycin resistance mutation by PCR has been studied recently, however, there have been few studies comparing treatment regimen in patient with clarithromycin-resistant H. pylori. We used sequencing-based clarithromycin resistance mutation and aimed to compare PAM (proton pump inhibitor, amoxicilline, metronidazole) regimen and PBMT (proton pump inhibitor, bismuth, metronidazole, tetracyclin) regimen in patient with clarithromycin-resistant H. pylori.
The purpose of this study is to know the distribution of Helicobacter pylori in stomach before subtotal gastrectomy and after subtotal gastrectomy.
With increasing antibiotic resistance and unsatisfactory results of empiric eradication regimens, tailored therapy may be the best choice to achieve high efficacy for rescue treatment. This study aimed to evaluate the eradication rates, safety, and compliance of antimicrobial susceptibility-based tailored therapy for rescue treatment in patients with Helicobacter pylori infection.
The objective of the study is to investigate prevalence of H.Pylori infection among acne vulgaris patients.
Dual therapy for Helicobacter Pylori including a proton pump inhibitor (PPI) and amoxicillin. Amoxicillin has low resistance rate as well as low percentage of side effects. No trial has examined the the efficacy of high dose of dual therapy plus bismuth for H. pylori treatment.This study is designed to evaluate the efficacy and safety of the addition of bismuth to high dose of dual therapy for H. pylori eradication.
