BACKGROUND There is interest in noninvasive H pylori testing as a means of predicting diagnosis and determining management in dyspeptic patients. AIMS To assess the value of the 14C urea breath test as a predictor of peptic ulcer disease in patients presenting with dyspepsia. PATIENTS AND METHODS 327 consecutive patients referred for investigation of dyspepsia had a 14C urea breath test per...

Helicobacter pylori is the cause of type B gastritis and associated with peptic ulcer disease. Various methods are available for detecting H pylori, but all have limitations. H pylori infection can be diagnosed by tests requiring endoscopy (rapid urease test, histology, culture) and by non-invasive tests (carbon-13 urea breath test, serology, stool tests). The urea breath test is currently the ...

Background: Chronic idiopathic urticaria is defined as urticaria, which lasts for more than 8 weeks and has no apparent etiology. The aim of this study was to examine the causal role of Helicobacter pylori infection in chronic idiopathic urticaria. Methods: Fifty-six patients with chronic idiopathic urticaria and a negative response to skin prick test for common aeroallergens were selected. The...

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...

Objective: The present study was conducted to evaluate invasive and noninvasive diagnostic methods for detection of Helicobacter pylori (H. pylori) in patients admitted with dyspeptic complaints and to compare sensitivities and specificities. Method: Sets of four gastric biopsy specimens were obtained from a total of 126 patients included in the study. The presence of H. pylori was determined b...
