Filter by:Helicobacter pylori is a Gram-negative bacterium with a helical bacillus shape that it's able to penetrate and colonize the stomach mucosal lining by infecting it. The eradication treatment of H. pylori is supported by numerous consensus groups worldwide and it is generally safe and well tolerated. Standard treatment is based on multiple drug regimens. However, its effectiveness has been increasingly compromised due to the emergence of resistant strains, as well as poor adherence to treatment. Therefore, it's proposed a randomized, double-blind, placebo-controlled study whose aims are: 1. Determine whether the combination of two probiotic strains of L reuteri (Gastrus) will improve gastrointestinal symptoms when associated with four-way therapy (of any type). 2. Prove whether supplementation with Gastrus (food supplement) versus Placebo is able to reduce the gastrointestinal adverse effects of quadruple eradication therapy. They will be determined by the GSRS gastrointestinal symptom scale in routine clinical practice.
Background: Helicobacter pylori infection, which affects over 50% of the global population, is one of the most prevalent infectious diseases in the world. H. pylori infection causes chronic active gastritis and is associated with peptic ulcer, lymphoma of the mucosa-associated lymphoid tissue and gastric cancer. The colonization of H. pylori in the hostile gastric environment is determined by the complex interactions among bacterial, environmental and host factors. Because of the emergence of antibiotic resistance and adverse drug reactions such as diarrhea, the successful rates with standard triple therapy for H. pylori eradication are falling. Vitamin D or its analogues was found to induce autophagy in keratinocytes, macrophages, and various cancer cell types. Our preliminary findings indicated that 1α,25-dihydroxyvitamin D3 could induce cathelicidin expression and autophagy in cultured human gastric epithelial HFE-145 cells and reduced the intracellular survival of H. pylori in a co-culture system. It was also found that cathelicidin alone reduced the survival of drug-resistant strain of H. pylori. 1α,25-dihydroxyvitamin D3 also significantly reduced H. pylori colonization in mice, perhaps through the induction of cathelicidin in the stomach. These findings suggest that vitamin D not only could control H. pylori but also its drug-resistant strains in humans. Emerging evidence suggest that vitamin D might be a cost-effective prophylactic and possibly therapeutic antimicrobial agent for the control and eradication of H. pylori. Since vitamin D acts through mechanisms independent of standard antibiotics, it is expected that vitamin D will be equally efficacious for controlling and eradicating drug-resistant strains of H. pylori. The investigators herein propose that vitamin D in combination of standard antimicrobial therapeutics could improve the eradication rates of drug-resistant H. pylori.
Helicobacter pylori is a bacterium estimated to colonize in the gastrointestinal tract of the half population in the world. Colonization of this bacteria is suspected to be one of the main risk factor for the occurrence of various abnormalities of the upper gastrointestinal tract, such as peptic ulcer and gastrointestinal cancer. The Experts recommend giving triple therapy regimens as first-line eradication therapy for Helicobacter pylori infection. The recommended duration of triple therapy is 10-14 days. However, recent studies suggest triple therapy with longer duration will provide a higher percentage of eradication. This study wanted to show whether 14 days of triple therapy was better than 10 days in Helicobacter pylori eradication.
This study compared efficacy and safety of basic triple therapy according to treatment period. This study evaluated Effect of CYP2C19 genetic polymorphisms on the efficacy
Helicobacter pylori (H.pylori) is a major human pathogenic bacterium in gastric mucosa which is linked to the development of gastritis, peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma and gastric cancer. However the regulatory mechanism of H.pylori-induced immune response is not clear. Long non-coding RNA (lncRNA) has recently emerged as key post-transcriptional regulators of gene expression, differentiation. The investigators had a preliminary results which THRIL (TNFα and hnRNPL related immunoregulatory lincRNA) and PACER(p50-associated COX-2 extragenic RNA) played a potential role in H.pylori induced inflammatory cascade. However, there wasn't a previous study about expression of THRIL, PACER in a human tissue. Therefore, the investigators aimed to evaluate the expression of THRIL, PACER in patients with gastrointestinal disease according to H.pylori infection.
There are lack of endoscopic criteria for diagnosing Helicobacter pylori (H. pylori) infection by conventional white light imaging (WLI). Linked color imaging (LCI) is a newly developed endoscopy technique, which can diagnose mucosal lesions and H. pylori infection by enhancing color contrast of the mucosa. The aim of the study is to investigate the ability of LCI for diagnosing H. pylori infection compared with WLI.
Helicobacter pylori (H. pylori), which infects about 50% of the global population, has been recognized as a main risk factor of multiple gastric pathologies, especially non-cardiac gastric cancer. Strongly evidence supports that H. pylori eradication is an effective approach to reduce the incidence of those pathologies.
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.
Approximately 50% of people in the world are infected with H. pylori, and its eradication rate fail to exceed 80% and even fails into an unacceptable range.Various risk factors for infection include lower socioeconomic status, younger age, and geographic location.In the present study, investigators aimed to perform a prevalence survey about risk factors for H. pylori infection.To obtain the higher eradication of H. pylori and find out the relevance between the diverse infection and clinical drug focused on refractory H. pylori infection.
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.
