Filter by: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.
Meta-analyses involving >4000 subjects with probiotics added to antimicrobial Helicobacter pylori eradication therapy in populations with antibiotic resistance have reported a mean increase in eradication rate of 12.2%. It is unclear how to translate that result into clinical practice. To evaluate whether administration of Lactobacillus reuteri plus a PPI without antibiotics would eradicate H. pylori infections. This was a double-blind placebo-controlled randomized 2 site study of L. reuteri (2 x 108 CFU L. reuteri DSM 17938 plus 2 x 108 CFU L. reuteri ATCC PTA 6475) 7 times per day or matching placebo plus 20 mg pantoprazole b.i.d. for 4 weeks. Cure was defined by negative 13C-UBT, 4 weeks after therapy. Sample size was based on obtaining >50% cures to be clinically useful as monotherapy.
The Asian-Pacific Consensus Report has recommended that proton pump inhibitor (PPI)-clarithromycin-amoxicillin or metronidazole treatment for 7 to14 days is the first choice treatment for H pylori infection. As a general rule for the treatment of other infectious diseases, clinicians should prescribe therapeutic regimens that have a per-protocol eradication rate ≥ 90% for anti-H pylori therapy. However, the eradication rate of the standard triple therapy has generally declined to unacceptable levels (i.e., 80% or less) recently. The reasons for this fall in efficacy with time may relate to the increasing incidence of clarithromycin-resistant strains of H. pylori. Clarithromycin resistance is the major cause of eradication failure for stand triple therapy. Standard triple therapies should be abandoned in the areas with clarithromycin resistance ≥ 20% because the per-protocol eradication rates of standard therapies are often less than 85% and the intention-to-treat eradication rates are usually less than 80%..7-10 day non-bismuth containing quadruple therapy (Concomitant therapy) had been successful in the presence of clarithromycin resistance. Another novel treatment with 14-day high dose PPI and amoxicilin dual therapy could also attained >90 eradication rate in some studies. This novel treatment is simple and involved only two drugs and the most important of all is that amoxicillin resistance is still 0% in Taiwan . High dose PPI has been used in several studies for H. pylori eradication in order to increase the intra-gastric PH for optimal eradication So far, there is still unclear which one is the best first-line H. pylori eradication regimen with highest eradication rate and least adverse effects. We therefore design a randomized controlled trial to simultaneously assess the efficacy novel 14-day high dose dual therapy by comparing to the 7-day non-bismuth containing quadruple therapy in Taiwan and to investigate the host and bacterial factors predicting the treatment outcomes of eradication therapies.
The diagnostic tests used to detect Helicobacter pylori (H. pylori) infection are either direct and invasive, as in culture, histology and the rapid urease test (RUT) or noninvasive, such as serology, the 13C-Urea breathe test or the stool antigen test. However, there is no single reference method to detect the H. pylori infection reliably and accurately. The specificity of gastric biopsy cultures is 100%, but the sensitivity is lower. Histology and RUT provide excellent diagnostic accuracy, but the detection of H. pylori is decreased in cases of bleeding peptic ulcers or gastric atrophy. Therefore, it is recommended that at least two tests should agree when defining the H. pylori infection in children. Quantitative real-time polymerase chain reaction (qPCR)-based methods have been shown to be the most reliable for H. pylori detection in adults and in children. In children, the reference method for H. pylori infection detection is invasive, namely upper digestive endoscopy with gastric biopsy for histology, culture, RUT and qPCR. A noninvasive alternative to detect H. pylori antigen in stools could use a quick one-step immuno-chromatographic technique. The aim of this study was to assess the performance of a new quick, noninvasive, one-step immuno-chromatographic, stool antigen test (ALERE Inc, Jouy-en-Josas, France) for the detection of H. pylori infection in children.
The current study is designed to demonstrate the non-inferiority of CJ-12420-based triple therapy (CJ-12420, amoxicillin and clarithromycin) versus lansoprazole-based triple therapy (lansoprazole, amoxicillin and clarithromycin) in H. pylori eradication rate and to evaluate the safety of CJ-12420 following oral administration of either triple therapy twice daily for 7 days in H. pylori positive patients.
The "test and treat" strategy for treating dyspeptic patients who are H. pylori positive is rapidly becoming the standard of care. This study will test the effectiveness of RHB-105, a new triple therapy to treat H. pylori infection in dyspeptic patients against an active comparator.
It was suggested that the patient compliance plans an important role in the Hp eradication. However, data on whether re-education could improve the eradication rate are lacking. We consider that re-education on patients by telephone during the process of drug administration could increase the eradication rate in Hp infected patients. We hypothesized that telephone re-education during the whole process of drug administration would improve the compliance of patients and ultimately increase the Hp eradication rate.
The aim of the study is to evaluate the effects of the synbiotic Bifidobacterium animalis ssp. lactis B94 plus inulin addition to the standard triple therapy on Helicobacter pylori infection eradication rates in children.
