Helicobacter pylori reinfection rate by a 13C-urea breath test and endoscopic biopsy tests in Korean children

Helicobacter pylori infection in type 1 diabetes children and adolescents using 13C urea breath test.

There is a 10-30% prevalence of HP infection in the general pediatric population in Poland. This study aimed to determine its prevalence in T1DM children in Upper Silesia, Poland and estimate its influence on metabolic control of patients. We studied 149 (82 female) children with T1DM (duration > 12 months, mean HbA1c) and 298 (164 female) age-matched controls. In all cases height and weight z-...

The urea breath test for Helicobacter pylori.

The 13C-urea breath test to detect Helicobacter pylori infection: a validated simple methodology with 50 mg 13C-urea.

BACKGROUND Several modifications of the 13C-urea breath test have been published. For reasons of cost efficiency and practicability, the urea dose and measurement duration should be reduced while still maintaining excellent diagnostic accuracy. AIMS To establish a validated simple protocol for the urea breath test with 50 mg 13C-urea and to compare this protocol with the conventional urea 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...

[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...
