Effect of posture on13C-urea breath test in partial gastrectomy patients

Prolonged effect of omeprazole on the 14C-urea breath test.

OBJECTIVES We investigated omeprazole's effect on 14C-urea breath testing. We also determined the duration of omeprazole's effect on the breath test. Finally, we studied whether effects on breath testing were dose dependent. METHODS Fifty-seven employees and outpatients were screened for Helicobactor infection. Those positive for serology, CLO, or histology were asked to undergo baseline brea...

Assessment of antibacterial effect of garlic in patients infected with Helicobacter pylori using urease breath test

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...

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...

The urea breath test for Helicobacter pylori.

Low dose capsule based 13c-urea breath test compared with the conventional 13c-urea breath test and invasive tests.

CONTEXT One of the limitations of 13C-urea breath test for Helicobacter pylori infection diagnosis in Brazil is the substrate acquisition in capsule presentation. OBJECTIVES The purpose of this study was to evaluate a capsule-based 13C-urea, manipulated by the Pharmacy Division, for the clinical practice. METHODS Fifty patients underwent the conventional and the capsule breath test. Samples...
