Helicobacter pylori is one of the most frequently occurring and persistent bacterial infections worldwide. H. pylori bacteria are associated with peptic ulcer disease, mucosaassociated lymphoid tissue lymphoma, and gastric cancer. Various diagnostic methods are used to detect H. pylori infection. However, only highly accurate tests with 90% sensitivity and 90% specificity should be used in clin...

BACKGROUND Chronic idiopathic urticaria (CIU) is one of the most frequent skin diseases, however its causes remain unknown in the vast majority of cases. There is increasing evidence for systemic effects of gastric Helicobacter pylori infection, which may result in extra gastrointestinal disorders. Although CIU can result from several causes, a possible relationship between chronic urticaria an...

Accurate noninvasive tests for diagnosing Helicobacter pylori infection in very young children are strongly required. We investigated the agreement between the [(13)C]urea breath test ([(13)C]UBT) and a monoclonal ELISA (HpSA) for detection of H. pylori antigen in stool. From October 2007 to July 2011, we enrolled 414 infants (123 from Brazil and 291 from Peru) of ages 6 to 30 months. Breath an...

Background: Acid test meals may improve the accuracy of the C urea breath test (UBT). This has been attributed to changes in gastric emptying rather than to the effects of gastric pH on Helicobacter pylori urease. Aims: To determine whether enhancement of CO2 excretion in the UBT in H pylori infected volunteers by acidification of a test meal is due to a delay in gastric emptying. Methods: Urea...

BACKGROUND A rapid, reliable, and sufficiently accurate test for diagnosing Helicobacter pylori infection is required for screening dyspeptic patients before a referral for endoscopy. The purpose of this article is two-fold: first, to evaluate the accuracy of a one-step H. pylori saliva antigen (HPS) test; and second, to compare noninvasive and invasive H. pylori tests in Taiwanese population. ...

BACKGROUND Hemodialysis is the most common method of renal replacement therapy for treatment of acute and chronic kidney failure. Helicobacter pylori (H. pylori) plays a major role in development of peptic ulcer, gastric neoplasms, and lymphoma as well as increased risk of cardiovascular disorders in hemodialysis patients. OBJECTIVES In this study the diagnostic values of noninvasive tests [i...

Background. We encountered repeatedly, in our clinical practice, discordant results between UBT and histopathology about H. pylori infection. Goal. To study the diagnostic accuracy of Heliprobe (14)C-urea breath test ((14)C-UBT) for detection of H. pylori infection in an Iranian population. Study. We enrolled 125 dyspeptic patients in our study. All of them underwent gastroscopy, and four gastr...

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/AIM Helicobacter pylori is an important human pathogen associated with gastric and duodenal ulcers, gastric mucosa- associated lymphoid tissue lymphoma, and adenocarcinoma. Radioiodine (RAI) treatment plays an important role in the management of differentiated thyroid cancer and primary hyperthyroidism. It is known that during RAI treatment, a considerable amount is absorbed by the s...
