Filter by:Gastric acid depressant play a major role in an H. pylori eradication therapy by (1) increasing the intragastric pH, which improves antibiotic stability and bioavailability; (2) increasing the intragastric pH to 6 or more, which prompts H. pylori to replicate and thus become more sensitive to antibiotics that are effective only against replicating bacteria, such as amoxicillin; (3) increasing the concentration of antibiotics in the stomach. Of antimicrobial agents against H. pylori, amoxicillin is a penicillin derivative that inhibits the synthesis of the bacterial cell wall. Therefore, amoxicillin's bactericidal effect requires the bacteria to be replicating. Amoxicillin is excreted by the kidneys, the plasma half-life is approximately 1 hour, and the bactericidal effect is time dependent. Theoretically, amoxicillin should be given 3 or 4 times daily to maximize the time above minimal inhibitory concentration (MIC) However, in most H. pylori eradication therapies, amoxicillin is given twice daily, where the estimated time above MIC attained by twice daily dosing is insufficient for amoxicillin. Because most strains of H. pylori are sensitive to amoxicillin, 3 or 4 times daily administration may be appropriate to increase the H. pylori eradication success. Nevertheless, data regarding the amoxicillin dosing interval for successful H. pylori eradication are lacking.
It is a single-centre, prospective cohort study, which will be conducted in a tertiary academic hospital. The study aims to investigate intrafamilial H. pylori infection status and to identify risk factors for H. pylori infection among household members. The rate of intrafamilial H. pylori spread in Hong Kong is currently unknown. It is also not clear whether the same risk factors for intrafamilial spread of H. pylori infection also apply in Hong Kong. In contrast to mainland China and Taiwan , recent consensus guideline on H. pylori management in Hong Kong in 2023 recommends against routine testing of asymptomatic household members or family members of H. pylori-infected adults. There is a knowledge gap on whether the family-based H. pylori screening is cost effective in our locality. Thus, the investigator aim to investigate infection status of household members of H. pylori infected individuals and risk factors for household infection in Hong Kong. The result from this study will shed light on the role of family-based screening and can inform future healthcare policy making on the strategy of H. pylori management and treatment in Hong Kong, ameliorating H. pylori infection-related disease and gastric cancer burden for society.
The purpose of this study was to evaluate the efficacy and safety of keverprazan with different doses of amoxicillin for Helicobacter Pylori.
Our study aimed to investigate the efficacy and safety of hybrid regimen as a first line therapy for H. pylori eradication compared to triple and quadruple regimens in attempt to overcome antibiotic resistance
Helicobacter pylori infection is a major cause of morbidity and mortality worldwide. More than 50% of the global population is estimated to be infected. In 2015, there were approximately 4.4 billion individuals with H pylori infection worldwide. In Pakistan the prevalence of H. pylori infection, highest (63%) in middle age (41-60 years) group while lowest (33%) in teens and pre-teens (<20 years) group. In young age (20-40) and old age (>60 years) groups, the prevalence of H. pylori was 55% and 60% respectively. In conventional system of medicine H. pylori infection is treated by triple regimen antibiotic therapy that are amoxicillin, clarithromycin and metronidazole along with acid reducing proton pump inhibitor. Due to recurrence of infection this therapy is repeated multiple times resulting in drug resistance and long term side effects. These side effects & a long term impact of H. pylori in patient general health necessitates development of a safe and long term effective therapy.
Gastric cancer remains a major challenge to public health on a global scale. H. pylori related cancer burden contributes to the largest proportion of cancer cases attributable to infections in Europe. Considering its absolute burden and persisting disparities, in addition to the substantial prevalence of H. pylori infection worldwide that is treatable, gastric cancer is a logical target for urgent action for prevention. Population-based H. pylori test-and-treat has therefore been proposed as a strategy for gastric cancer prevention. To fill the gaps in knowledge about gastric cancer prevention through H. pylori screening and eradication in younger adults, a study of a population-based H. pylori test-and-treat strategy in Ireland, Croatia, Latvia, Poland, Romania and Slovenia. Main goals of this study are to assess future program processes, feasibility, acceptability and effectiveness. In total of 6,800 adults aged 30-34 will be tested for H. pylori infection. They will be randomly selected to represent the chosen population and invited to participate in the study based on informed consent. Confirmed infections will be treated by available combined therapy in line with treatment guidelines and the success of eradication will be retested during a control check-up. Patients who will provide their consent to participate will undertake an interview about the risk factors in early childhood and their habits regarding alcohol consumption and use of tobacco. Compliance to testing and treatment, treatment results, adverse effects and reasons for dropping out will be additionally monitored. Gathered data will be analysed in alignment with our research questions. The investigators will disseminate reports and present the results to both the general public and the scientific community in order to foster future developments in gastric cancer prevention.
The primary objective of this study is to : find the relation between H.pylori infection and pre-diabetic patients with lipid profile . Specifically, the study aims to: 1. affect of H.pylori infection in pre-diabetic patients 2. realation between Pre-diabetic patient and lipid profile 3. Risk factor of H.pylori infection in pre-diabetic patients D)HbA1C test measures your average blood sugar level over the past 2 or 3 months. e)Fasting Blood Sugar Test. f) the IgG antibody of h.pylori.
All patients who presented with epigastric pain and dyspeptic symptoms will undergo endoscopic gastric biopsies. The patients will be subjected to: Full history taking, clinical examination, liver function tests, renal function tests, CBC, INR, abdominal ultrasonography. About 200 patients diagnosed to have H. pylori by infection by microscopically examined, endoscopic gastric biopsies will be enrolled in our study. All available formalin fixed and paraffin embedded tissue blocks of gastric endoscopic biopsies will be resectioned and stained with Haematoxylin and Eosin. Modified Giemsa stain, and Alcian blue/ PAS stain will be used for verification of Helicobacter pylori and demonstration of intestinal metaplasia respectively. Biopsies will be classified using the Updated Sydney system of classification of gastritis
Helicobacter pylori (H. pylori) is a serious health threat that infects approximately half of the global population. In addition to colonizing the stomach, H. pylori has been shown to survive in the oral microenvironment and is associated with a variety of oral diseases, gastric eradication failure, and reinfection. Currently, traditional systemic antibiotic therapy has little effect on oral H. pylori, and mouthwashes available on the market for oral H. pylori eradication often contain multiple antibiotics or complex essential ingredients, which can cause unpredictable effects on the human body. Therefore, there is an urgent need for a mouthwash that does not contain antibiotics and is effective against oral H. pylori. This study focuses on the eradication effect of MAXPOWER Biological Antibacterial mouthwash on oral H. pylori in a population.
The goal of this randomized, open-label, interventional trial is to study the efficacy of treatment for Helicobacter Pylori Infection in Preschooler aged 4-6 by Meiji Yoghurt with LG21. The main question it aims to answer is: - whether the treatment by Meiji Yoghurt LG21 is effective by stool antigen (HpSA) test 140 qualified participants will be enrolled and randomized into 2 groups of the same size (product study group and blank control group). Participants of the product study group will need to eat assigned Meiji Yoghurt for 12 weeks, one bottle each day, while participants of the blank control group won't receive any intervention during the study. Four visits will be made for all participants, and relevant clinical data will be captured and recorded into CTMS (Clinical Trial Management System) for statistical analysis and reporting.
