Filter by:This study is conducted to investigate whether the efficacy of single-dose triple therapy (Esomeprazole 40 mg, Tinidazole 1 g, and Levofluxacine 500 mg) for 14 days is superior to double-dose lansoprazole 30 mg, amoxicillin 1 g and clarithromycin 500 mg for 14 days in the treatment of H pylori infection.
To compare the eradication success rate between 10-days sequential therapy and 7-days tailored therapy based on H. pylori culture and antimicrobial susceptibility testing.
As increasing the antibiotics resistance, the effectiveness of traditional Helicobacter pylori (H. pylori) therapies has been declined coincidentally. In this study, the investigators evaluated the efficacy of H. pylori eradication between a 7 days personalized therapy for H. pylori infection based on the results of antibiotics resistance by using H. pylori culture and minimal inhibitory concentration (MIC) and the 14 days bismuth contained quadruple 2nd rescue regimens, and the investigators analyzed the prevalence of the antibiotic resistance after 1st eradication of H. pylori in the tailored therapy group.

Helicobator pylori (H. pylori) is a bacteria which survives in the lining of the stomach. An estimated 50% of the world's population is infected with H. pylori. Developing economies, such as in Southeast Asia, the Indian subcontinent and Latin America, have prevalence rates of as high as 90%. H. pylori infection often goes undiagnosed, as many sufferers do not experience any adverse symptoms. Infection with H. pylori is described as "not a disease in itself but a condition that affects the relative risk of developing various clinical disorders of the upper gastrointestinal tract.' Clinically relevant symptoms could include peptic ulcer, melena or secondary conditions such as iron deficiency anemia or vitamin B12 deficiency. There is evidence that probiotics can be beneficial for those with gastrointestinal diseases. Pylopass contains the probiotic strain Lactobacillus reuteri, which was selected for its anti-H. pylori characteristics and in clinical trials has shown to result in a reduction in urease breath test values in subjects with H. pylori. The objective of this study is to evaluate the ability of Pylopass to reduce H. pylori load in subjects who are H. pylori positive.
Traditionally, H pylori infection has been treated with conventional triple therapy. This includes amoxicillin, clarithromycin and a proton pump inhibitor all given daily for 10-14 days. In Europe, the guidelines now advocate treatment of H pylori with sequential therapy which is 5 days of amoxicillin therapy with proton pump inhibitor followed by 5 days of clarithromycin, metronidazole, and proton pump inhibitor with better response rates. We hypothesize that H. pylori resistance pattern and treatment response rates observed in Europe will not be predictive of resistance patterns and response rates in the United States.
Up to now, to our knowledge, there is few randomized, large scale study prospectively and simultaneously comparing the efficacy, adverse effects and patient adherence of these current recommended 1st-line or 2nd-line regimens for H. pylori eradication in and out of our country. The aims of this study are: 1. to compare the efficacy of high dose dual therapy, sequential therapy and clarithromycin-based triple therapy as 1st-line regimen in H. pylori eradication; 2. to compare the efficacy of high dose dual therapy, sequential therapy and levofloxacin-based triple therapy as rescue regimen in H. pylori eradication; 3. to compare the patient adherence and adverse effects of these treatment regimens; 4. to investigate factors that may influence H. pylori eradication by these treatment regimens; 5. to investigate and analyze the prevalence and trend of antibiotic resistance.
At present, triple therapy are recommended by various guidelines for the treatment of Helicobacter pylori (H. pylori) infection. Recent studies have shown worldwide high treatment failure rates with one week first line clarithromycin based triple therapy necessitating salvage strategy to eradicate H. pylori in primary treatment failure. However, the exact duration of bismuth based second line treatment is not determined. Therefore, the investigators performed this study to evaluate the eradication rate of 1 or 2-week quadruple regimen as a second-line therapy.
Helicobacter pylori is a bacteria that infects the lining of the stomach and is associated with ulcers. Helicobacter pylori may also increase the long-term risk of developing certain forms of gastric cancer. Curing this infection generally requires that patients take 2 or more antibiotic medications and a stomach acid suppressing medication for about two weeks. Current treatments do not always cure the infection and a new treatment is being tested in this study. The drugs involved in the new 4 drug treatment have been widely used for treatment of this infection. It remains unknown what is the best and most cost effective way to give them. This study will compare three different ways of using these drugs. Subjects must have active Helicobacter pylori infection in order to participate in this study.
