Patients of chronic gastritis should be investigated with gastric mucosal biopsy, parietal cell antibody, intrinsic factor antibody, Helicobacter pylori antibody, urea breath test or faecal antigen test for Helicobacter pylori, to accurately classify them. The results of these tests will indicate Helicobacter pylori infection (present or past), the role of hereditary factor (intrinsic factor an...
13C-breath tests are widely applied as a tool to investigate metabolic processes and infectious diseases, but most of them have not yet entered into clinical practice. In order to promote the introduction of more 13C-breath tests into clinical routine application we evaluated the tests so far known with respect to some reasonable criteria, which are valued by one of three marks. The sum sigma o...
BACKGROUND AND PURPOSE (13)C-urea may be a suitable marker to assess the in vivo fate of colon-targeted dosage forms given by mouth. We postulated that release in the colon (urease-rich segment) of (13)C-urea from colon-targeted capsules would lead to fermentation of (13)C-urea by bacterial ureases into (13)CO(2). Subsequent absorption into the blood and circulation would lead to detectable (13...
Breath tests (BT) represent a valid and non-invasive diagnostic tool in many gastroenterological disorders. Their wide diffusion is due to the low cost, simplicity and reproducibility and their common indications include diagnosis of carbohydrate malabsorption, Helicobacter pylori infection, small bowel bacterial overgrowth, gastric emptying time and orocaecal transit time. The review deals wit...
objective: helicobacter pylori (h. pylori) is the most common pathogenic bacteria in the stomach. the aim of the current study was to explore the effect of oral garlic administration on bacterial urease activity inside the stomach and its contribution to the treatment of h. pylori infection. materials and methods: in this clinical trial, 15 patients were studied quantitatively with urease bre...
background: to estimate the prevalence of small intestine bacterial overgrowth (sibo) among patients with irritable bowel syndrome (ibs) versus healthy subjects with the use of a glucose breath test (gbt) in our geographical area. materials and methods: this study included a total of 80 consecutive patients; 40 with ibs based on rome iii criteria and 40 healthy controls with similar age and sex...
BACKGROUND Carbon labeled urea breath tests usually entail a two point sampling with a 20 to 30-minute gap. Our aim was to evaluate the duration of time needed for diagnosing Helicobacter pylori by the BreathID® System. METHODS This is a retrospective multicenter chart review study. Test location, date, delta over baseline, and duration of the entire test were recorded. Consecutively 13C urea...
