AIM To determine the sensitivity and specificity of the 13C-urea breath test (UBT) in patients taking proton pump inhibitors (PPIs), using a new test meal Refex. METHODS One hundred and fourteen consecutive patients with dyspepsia, 53 Helicobacter pylori (H. pylori) positive, 49 H. pylori negative, were included in the study. The patients were then given esomeprazole 40 mg for 29 consecutive ...

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 Despite many changes, no large studies comparing the different diagnostic tests for Helicobacter pylori have been performed in the past 10 years. In this time, monoclonal stool antigen immunoassays and in-office 13C-urea breath tests (UBTs) have appeared. The aim of this study was to evaluate the accuracy of invasive and noninvasive tests in a large series of dyspeptic patients. ME...

Purpose of research. Assessment the population prevalence Helicobacter pylori infection and effectiveness eradication therapy by analyzing results 13 C-urease breath test ( C-UBT) surveyed patients who applied for to nationwide network medical offices INVITRO laboratory in 2019-2020. Materials methods. C-UBT was performed using C-UREA TEST kits IR spectrometer IRIS° - Doc, Kibion AB, Sweden. A ...

The [(13)C]urea breath test ((13)C-UBT) and Helicobacter pylori stool antigen test (HpSA) for the diagnosis of H. pylori infection in children were validated. The sensitivity, specificity, and positive and negative predictive values were 93.8, 99.1, 97.8, and 98.0%, respectively, for the (13)C-UBT and 96.9, 100, 100, and 98.0%, respectively, for HpSA. Both tests are appropriate for diagnosing H...

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...

OBJECTIVES Only recently it has been proven that cystic fibrosis (CF) patients have the same prevalence of Helicobacter pylori (HP infection) as the general population, as well as the same spectrum of changes caused by this pathogen. The aim of this study was to assess the reliability of the two most popular noninvasive tests--the urea breath test (UBT) and the fecal test (FT) in diagnosing HP ...

OBJECTIVE To investigate the prevalence of Helicobacter pylori (Hp) infection in pre-school and school age children with C-14 urea breath test, and to explore its association with age and socioeconomic factors in Turkey. METHODS Hp infection status was determined by using Urea Breath Test (UBT). Patients who had previous gastric surgery, Hp eradication treatment or equivocal UBT results were ...

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...
