aim : to evaluate the diagnostic value of helicobacter pylori stool antigen test before and after eradication background : there are different methods for diagnosis and follow up of helicobacter pylori infection, including invasive methods done with endoscopy and non invasive ones such as ubt and urine analysis antibody. one of non invasive new methods is analysis of helicobacter pylori stool a...

The longitudinal stability of the urea breath test (UBT), which measures urease as a biomarker for infection with Helicobacter pylori (a major risk factor for gastric cancer), was evaluated in the environs of Tsukuba, Japan. 13C-UBT measurements were monitored at four time points in 46 free-living, H. pylori-infected, asymptomatic volunteers over a period of 7 weeks. Subjects were asked to refr...

BACKGROUND It has been debated which diagnostic test should be preferred for the diagnosis of Helicobacter pylori (HP) in patients with peptic ulcer diseases. Several limitations are reported in bleeding peptic ulcers because of intragastric blood and possibility of changed numbers of organisms by medication. This study was designed to find out the best method for diagnosis of HP infection, in ...

BACKGROUND The 13C-urea breath test (UBT) is performed in adults and children with epigastric pain for non-invasively diagnosing a suspected H. pylori infection. Criteria for UBT interpretation have not been generally agreed on and test reliability has not been established in children of different ages. This study aimed at identifying reliable UBT thresholds in children by using 251 UBTs in con...

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...

ba ckground: there have been a number of reports indicating that garlic can inhibit helicobacter pylori ( h. pylori ) in vitro ; however, there is few clinical trials evaluating its effect in human infection. the aim of this study was to assess the effect of garlic consumption on urea breath test (ubt) results in patients with h. pylori infection. m ethods: we performed a randomized case-contro...

AIM to obtain the proportion of dyspepsia symptom in non-ulcerative dyspepsia patient after eradication treatment of H. pylori, and recent status of H. pylori after eradication therapy. METHODS cross-sectional study in patients with history symptoms of dyspepsia in non ulcer dyspepsia with positive H. pylori and had been administered eradication treatment of H. pylori for 1 week in 2002-2007 ...

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 The treatment failure rate for Helicobacter pylori eradication therapy is ~20% due to poor patient compliance and increased antibiotic resistance. This analysis assessed the cost-effectiveness of universal post-treatment testing to confirm eradication of H. pylori infection in adults. METHODS Decision-analytic models evaluated the cost-effectiveness of universal post-treatment test...

OBJECTIVE To compare the current non-invasive tests for Helicobacter pylori infection in children and adolescents. STUDY DESIGN This multicenter, multinational study investigated the sensitivity, specificity, and positive and negative predictive values of four non-invasive tests: urea breath test (UBT), stool antigen test, and antibody detection in serum and urine, in comparison with biopsy-b...
