The urea breath test for Helicobacter pylori.

The urea breath test for Helicobacter pylori.

Effect 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...

Pharmaceutical 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...

Urea Breath Tests for Detection of Helicobacter pylori

The association ofHelicobacter pyloriwith peptic ulcer disease and gastric cancer was first proposed by Warren and Marshall in 1983 (Warren and Marshall, 1983). In February 1994, the National Institutes of Health Consensus Development Conference concluded thatH. pylori infection is themajor cause of peptic ulcer disease, and all patients with confirmed peptic ulcer disease associatedwithH. pylo...

[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...
