Filter by:The overall prevalence of H. Pylori in the developing countries is 50.8%, with the highest one presented in Africa (79.1%). Hybrid therapy is supposed to be more effective as a first-line regimen for Helicobacter pylori infection in Egypt than the Reverse hybrid and non-bismuth Levofloxacin quadruple therapies. We are aiming here to compare the Hybrid, Reverse hybrid, and Levofloxacin quadruple therapies as first-line therapy, trying to reach the safest, cost-effective, and compliance-inducing regimen in Egypt. We will conduct a randomized controlled (interventional) study at Zagazig University Hospital, internal medicine department clinic, on 330 patients. 110 patients will be allocated to each regimen.
H pylori is an important cause of chronic gastritis and other complications. There is a decline in eradication rate for H pylori owing to multiple factors including drug resistance. We compare the effect of the addition of bismuth to the standard triple therapy in a randomized control trial. Subjects were randomized into two arms. Arm A received triple therapy including amoxicillin, clarithromycin, and omeprazole and Arm B received quadruple therapy adding colloidal bismuth subcitrate. Both arms received treatment for two weeks.
The investigators investigated the point mutations in the 23S rRNA genes of patients infected with clarithromycin-resistant H. pylori and compared the H. pylori eradication rates based on the identified clinically significant point mutations.
Helicobacter pylori (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. The eradication of H. pylori can reduce the recurrence rate of peptic ulcer disease and even has the potential to prevent gastric cancer. 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. Triple therapy which contains a proton pump inhibitor and two antibiotics among clarithromycin, amoxicillin, and metronidazole is the most commonly used regimen for H. pylori eradication. The treatment duration is 7 to 14 days. However, the eradication rate of standard triple therapy has fallen below 80% in many countries due to the worldwide increasing prevalence of antibiotic resistant strains. Several strategies have been proposed to increase the eradication rate in the first line therapy or as a rescue therapy, including extending the treatment duration to 14 days, increasing the doses of antibiotics, the use of four or even five drugs regimen (sequential, concomitant, quadruple or quintuple therapy), and other antibiotics such as levofloxacin. However, these therapies may increase the side effects and costs of treatment, decrease the compliance of patients and increase the rate of worldwide antibiotic resistance steadily. The WHO has listed H. Pylori as one of 16 antibiotic-resistant bacteria that have the greatest threat to human health in February, 2017. The most commonly used oral antibiotics for the treatment of H. pylori are Amoxicillin、Clarithromycin、Metronidazole、Levofloxacin and Tetracycline. However, with the increasing rates of antibiotic-resistance for Clarithromycin and Metronidazole, the Clarithromycin and Metronidazole were replaced by Levofloxacin as a first line or second line treatment in some area. However, the eradication rate of Levofloxacin-containing triple therapy is suboptimal in many countries. The investigators aim to compare the efficacy of different formulation between Levofloxacin Powder and Levofloxacin Solution in the Intraluminal levofloxacin therapy, and to improve the eradication efficacy of one-week Levofloxacin-containing triple therapy via the Intraluminal therapy.
Background: Recommended proton pump inhibitor (PPI)-clarithromycin-amoxicillin or metronidazole treatment for 7 to14 days is the first choice treatment for H pylori infection. The eradication rate of the standard triple therapy has generally declined to unacceptable levels (i.e., 80% or less) recently because the increasing incidence of clarithromycin-resistant strains of H. pylori. Standard triple therapies should be abandoned in the areas with clarithromycin resistance ≥ 20%. The investigators have proven that 7-day Concomitant therapy can achieve a promising success rate of >90 % in the presence of clarithromycin resistance. However, high dose PPI is needed with a dosage of twice daily but when a dual delayed release formulation PPI in capsules for oral administration (Dexlansoprazole MR), a once daily dose may be needed only. The capsules contain dexlansoprazole in a mixture of two types of enteric-coated granules with different pH-dependent dissolution profiles. It suppresses gastric acid secretion via inhibition of the proton pump in the gastric parietal cell, which blocks the final step of acid production. Thus, it improves acid suppression and offer benefits over conventional single release PPI formulations. by prolonging optimal plasma concentration and create a favorable condition H. pylori eradication Aim: The efficacy of Dexlansoprazole MR-based concomitant quadruple therapy
Introduction: Helicobacter pylori has been linked to a variety of gastric and extra gastric diseases. Chronic infection with H. pylori causes histologically evident gastritis in all colonized individuals and is the predominant risk factor for gastric and duodenal ulcers as well as gastric adenocarcinoma. However, increasingly robust experimental and epidemiological evidence suggests that H. pylori may at the same time be beneficial to its carriers, as it efficiently prevents allergic disorders and chronic inflammatory conditions . Inflammatory bowel disease (IBD) is characterized by chronic, nonspecific intestinal inflammation with an unexplained pathology and an alternating relapsing and remitting clinical progression. IBD is divided into two subtypes: ulcerative colitis (UC) and Crohn's disease (CD). Most studies in the IBD field attribute its etiology to the complex interactions among immune dysfunction, genetic susceptibility of the host, and environmental risk factors. Since the twenty-first century, improving hygienic conditions and socioeconomic status have reduced the H. pylori infection rate and this trend has concurrently been accompanied by an increased IBD incidence in most countries Numerous studies have reported a lower H. pylori infection rate in patients with CD and/or UC than in non-IBD control individuals. although a small number of studies showed no significant association .Recently, emerging epidemiologic studies and animal experiments revealed an inverse correlation between H. pylori infection and IBD onset, suggesting that H. pylori colonization exerts a special protective effect on autoimmune diseases observation Cross sectional study will be conducted at assuit university hospitals on all patients with inflammatory disease to detect the prevalence of helicobacter pylori among them .Then the examined patients will be divided in to two group receiving the same medication group A : inflammatory bowel disease patient with H.PYLORI group B: inflammatory bowel disease Patient without H.PYLORI longitudinal study will be conducted to both group to study the clinical outcomes in both group .
South Korea has the highest incidence of gastric cancer worldwide and Helicobacter pylori infection is still prevalent. Clarithromycin-containing triple therapy is still the primary therapy approved by the Korean government. However, studies of antibiotic resistance has shown that regional resistance pattern to antibiotics such as clarithromycin, metronidazole, or quinolone. Recent study in Korea has shown that modified-quadruple therapy has comparable eradication rate to concomitant therapy. However, there has been no comparable study of modified-quadruple therapy with bismuth-containing quadruple therapy. The aim of this study is to compare the eradication rate of modified-quadruple therapy and bismuth-containing quadruple therapy with presenting phenotypic and genotypic antibiotic resistance profile.
The purpose of this study is to assess efficacy of 14-day antimicrobial susceptibility test guided quadruple therapy for the rescue treatment of Helicobacter pylori infection, then comparing it with 14-day empirical therapy according to personal medication history.
The efficacy of conventional systemic antibiotic therapy for eradication of gastric H. pylori has been seriously challenged by antibiotic resistance. Identification of alternative therapeutic strategies might help to overcome the limitation. The investigators' aim was to examine the effect of adjunct periodontal therapy, on gastric H. pylori eradication rate.
The aim of the study is to compare the effectiveness of two therapeutic protocols in the treatment of Helicobacter pylori infection. The hypothesis of our research is that the two therapeutic options (hybrid and concomitant therapy) will be equally successful in the treatment of Helicobacter pylori infection. In other words, in both therapeutic groups we expect successful treatment of Helicobacter pylori infection in or more than 90 % of patients. In other studies, both therapeutic options have the same efficacy in treating H. pylori infection. On the other had there are no studies available in Croatia to compare the effectiveness of these therapeutic options so far, which is the main objective of our research. The secondary goals of our study will be: the existence of differences in the occurrence of possible side effects, as well as the compliance between patients in both therapeutic options. It is also our aim to compare the quality of life of patients with Helicobacter pylori infection before and after treatment, via a questionnaire that is common for this purpose. The study is expected to include a total of 120 patients (60 patients in each therapy group), and the planned duration is 12 months.
