Comparison of isotope ratio mass spectrometry and nondispersive isotope-selective infrared spectroscopy for 13C-urea breath test.
1999
The 13C-urea breath test (UBT) is a sensitive and noninvasive method to diagnose Helicobacter pylori infection, but mass spectrometry (IRMS) is very expensive. The aims of this study were to compare the new low-priced infrared spectroscopy with IRMS in detecting the infection and to assess the influence of feeding on test accuracy.One hundred thirty-four patients with dyspeptic symptoms were recruited. Of these, 74 were infected and 60 uninfected on the basis of both CLO-test and histology. A subgroup of 37 patients (22 H. pylori-positive and 15 H. pylori-negative) was studied under fasting and nonfasting conditions on two different days. Duplicate breath samples were analyzed with two IRMS…
Comparable Helicobacter pylori eradication rates obtained with 4- and 7-day rabeprazole-based triple therapy: a preliminary study
2003
Abstract Background. Rabeprazole is a new proton pump inhibitor, which has been reported to induce a faster acid suppression than other drugs of the same category. This might be useful to reduce the duration of anti-Helicobacter therapies. Aims. The aim of this study was to assess whether there is the possibility of shortening a rabeprazole-based triple therapy from 7 to 4 days without compromising its efficacy in the eradication of Helicobacter pylori infection. Patients. A total of 128 consecutive dyspeptic patients with H. pylori infection were recruited for this controlled, randomized, open and parallel-group trial comparing the efficacy of two durations of the same rabeprazole-based tr…
European Registry on Helicobacter pylori management (Hp-EuReg): patterns and trends in first-line empirical eradication prescription and outcomes of …
2020
ObjectiveThe best approach for Helicobacter pylori management remains unclear. An audit process is essential to ensure clinical practice is aligned with best standards of care.DesignInternational multicentre prospective non-interventional registry starting in 2013 aimed to evaluate the decisions and outcomes in H. pylori management by European gastroenterologists. Patients were registered in an e-CRF by AEG-REDCap. Variables included demographics, previous eradication attempts, prescribed treatment, adverse events and outcomes. Data monitoring was performed to ensure data quality. Time-trend and geographical analyses were performed.Results30 394 patients from 27 European countries were eval…

BACKGROUND: Although the stomach is the most frequent site of intestinal lymphomas, few data are available on both clinical endoscopic presentation of gastric lymphoma and p…
Does Family History of Cancer Influence Undergoing Screening and Gastrointestinal Investigations?
2020
Background and Aims: Although a family history of cancer (FHC) can modify the lifestyle and attitudes towards participation in cancer screening programs, studies on this relationship show mixed results and vary across populations. The objectives of the study were to compare sociodemographic characteristics, history of gastrointestinal (GI) investigations and Helicobacter pylori eradication, and modifiable cancer risk factors between those with FHC and those with no FHC (NFHC), and to investigate the association between FHC and a history of GI investigations.
 Methods: A total of 3,455 questionnaires from the pilot study of the “Helicobacter pylori eradication and pepsinogen testing for…
Review: Epidemiology of Helicobacter pylori.
2020
This review summarizes the recent knowledge on the epidemiology of Helicobacter pylori and the potential modes of transmission. In addition to English language publications, the authors have included original full-text publications from Russia and Latin America published in the original languages. High H pylori prevalence has been reported in Russia, Jordan, Iran, China, and Latin American countries as well as in Arctic populations in Canada. Indigenous inhabitants in the Arctic were found to be infected substantially more frequently than non-indigenous inhabitants. In Amsterdam, the Netherlands, the ethnic minority groups were at a significantly higher risk of being H pylori seropositive c…
Helicobacter pylori and some aspects of gut microbiota in children
2018
Helicobacter pylori infection in children differs from infection in adults in many aspects. The rate of infection, epidemiology, clinical presentations and complications, the applicability of diagnostic tests, antibiotic resistance, treatment options, and success rates differ significantly. Due to all these differences, management guidelines for children and adults differ also substantially. In 2017, the Updated ESPGHAN and NASPGHAN Guidelines on the management of H. pylori infection in children were published, emphasizing the differences in clinical presentation and indications for treatment, stating that the primary goal of clinical investigation in children is to identify the cause of up…
Diagnosing Helicobacter pylori in vivo by confocal laser endoscopy.
2005
Background & Aims: Confocal laser endomicroscopy enables subsurface microscopic imaging of living tissue during ongoing endoscopy. This case report describes the in vivo detection of Helicobacter pylori by endomicroscopy.Methods: Endomicroscopy (Pentax, Tokyo, EC-3870CIFK) was performed by using two different contrast stains: Topical Acriflavine in addition to intravenously applied fluorescein netted the surface and allowed identification of focal accumulation of Helicobacter pylori at the surface and in deeper layer of the gastric epithelium. Biopsies were performed at the antrum and corpus for urease testing and histology. In addition, biopsies were cultured for Helicobacter pylori. Cultu…
A new 1-week therapy for Helicobacter pylori eradication: rani- tidine bismuth citrate plus two antibiotics
1997
Background: One-week triple regimens are currently the most recommended therapy for the eradication of Helicobacter pylori. No previous study has evaluated the efficacy of a short-term regimen combining ranitidine bismuth citrate with two antibiotics. Methods: Seventy-two consecutive H. pylori-positive dyspeptic patients were recruited for this randomized, three-centre, open, parallel-group study. They were subdivided into two groups receiving either ranitidine bismuth citrate 400 mg b.d. + clarithromycin 250 mg b.d. and metronidazole 500 mg b.d. (group A) or ranitidine bismuth citrate 400 mg b.d. + clarithromycin 250 mg b.d. and metronidazole 250 mg q.d.s (group B) for 1 week. H. pylori in…
