[Validation of a simplified 13C-urea breath test method for the diagnosis of Helicobacter pylori infection].
OBJECTIVE To validate a simplified 13C-urea breath test (13C-UBT) method for the diagnosis of H. pylori infection. MATERIAL AND METHODS Patients referred for gastrointestinal endoscopy and biopsy were included, and a 13C-UBT was performed after a 6-hour fast. Breath samples were collected in 10 ml glass tubes before and 30 min after the simultaneous administration of 50 mg of 13C-urea and 2 g...
متن کاملUrea breath tests in the management of Helicobacter pylori infection.
The 13/14C-Urea breath test (UBT) is based on the simple principle that a solution of isotopically labelled urea will be rapidly hydrolysed by the abundantly expressed urease of H pylori. The released 13/14CO2 is absorbed across the mucus layer to the gastric mucosa and hence, via the systemic circulation, excreted in the expired breath. Distribution of urea throughout the stomach prevents samp...
متن کاملPharmaceutical interference with the [14C] carbon urea breath test for the detection of Helicobacter pylori infection.
Helicobacter pylori bacteria reside in the mucosal lining of the stomach where, due to a variety of factors, the infection predisposes patients to peptic ulcer disease. Detection of H. pylori is important in the treatment and follow-up of patients with peptic ulcer disease and the urea breath test is the method of choice. This article will briefly review the methods for diagnosing H. pylori, em...
متن کاملEffect of a test meal on the intragastric distribution of urea in the 13C-urea breath test for Helicobacter pylori.
Test meals are invariably used in the 13C-urea breath test (UBT) but their effect on the intragastric distribution and gastric residence time of urea given in the test is unknown. The site of Helicobacter pylori urease measured in the test is unknown and whether the test measures total or regional gastric urease is uncertain. This study reports the results of paired UBTs with simultaneous gastr...
