The urea breath test UBT C13,14 is a good rapid diagnostic procedure used to identify stomach infections by H. pylori. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide. Urea breath tests are recommended in leading society guidelines as a preferred non-invasive choice for detecting H. pylori of stomach before and after treatment with diagnostic efficacy at ...

BACKGROUND This study was conducted to evaluate the diagnostic validity of the (13)C-urea breath test ((13)C-UBT) in the remnant stomach after partial gastrectomy for gastric cancer. METHODS The (13)C-UBT results after Helicobacter pylori eradication therapy was compared with the results of endoscopic biopsy-based methods in the patients who have received partial gastrectomy for the gastric c...

OBJECTIVES To assess the cost-effectiveness of alternative initial strategies in the management of uninvestigated dyspepsia in adult patients presenting to a primary care physician in Canada. METHODS Clinical decision-making was modeled based on outcomes data from the literature and expert opinion. Costs were obtained from official reimbursement lists, and a detailed microcosting analysis of ...

BACKGROUND/AIMS The (13)C-urea breath test (UBT) is a semiquantitative test for measuring Helicobacter pylori infection loading. H. pylori produces ammonia, which elevates the pH of the gastric mucosa and is detectable via endoscopy using a phenol red indicator. We evaluated whether this test could be used to diagnose H. pylori infection and whether phenol red staining was correlated with (13)C...

BACKGROUND The 13C urea breath test (13C-UBT) is the gold standard for detecting Helicobacter pylori infection. H. pylori pathogenesis in patients with hepatitis B virus (HBV) and related diseases remains obscure. We used 13C-UBT to detect H. pylori infection in patients with chronic HBV infection, HBV-related cirrhosis, HBV-related hepatic carcinoma, and other chronic hepatic diseases. METHO...

IMPORTANCE The long-term effectiveness of Helicobacter pylori eradication programs for preventing gastric cancer will depend on recurrence risk and individual and community factors. OBJECTIVE To estimate risk of H. pylori recurrence and assess factors associated with successful eradication 1 year after treatment. DESIGN, SETTING, AND PARTICIPANTS Cohort analysis of 1463 randomized trial par...

OBJECTIVE Previous US-based economic models of noninvasive tests for diagnosis of Helicobacter pylori infection did not consider patient adherence or downstream costs of continuing infection. This analysis evaluated the long-term cost-effectiveness of the urea breath test (UBT), fecal antigen test (FAT), and serology for diagnosis of H. pylori infection after incorporating information regarding...
