PURPOSE Helicobacter pylori is one of the most prevalent infectious agents in the world which causes a variety of gastrointestinal diseases including gastritis, peptic ulcer and gastric carcinoma. The objective of this study was to comparatively evaluate invasive (rapid urease test and polymerase chain reaction) and non-invasive (enzyme-linked immunosorbent assay) tests in diagnosis of infectio...

Among the methods developed to detect H. pylori infection, determining the gold standard remains debatable, especially for epidemiological studies. Due to the decreasing sensitivity of direct diagnostic tests (histopathology and/or immunohistochemistry [IHC], rapid urease test [RUT], and culture), several indirect tests, including antibody-based tests (serology and urine test), urea breath test...

OBJECTIVE To validate a rapid urease test (RUT) in Cayetano Heredia Hospital (HCH) in Lima, Peru. MATERIALS AND METHODS This is a prospective observational study that included 181 patients over 18 years old with dyspeptic symptoms. All of them underwent upper gastrointestinal endoscopy at the Department of Gastroenterology at HCH. They had not received, during the last four weeks, proton pump...

background: helicobacter pylori (h.pylori) infection causes multiple upper gastrointestinal diseases but optimal therapeutic regimen which can eradicate infection in all the cases has not yet been defined. this study was designed to evaluate the efficacy of triple levofloxacin-based versus clarithromycin-based therapy. methods: in this open-label randomized clinical trial study 120 patients who...

BACKGROUND Current diagnosis of Helicobacter pylori infection by biopsy-based tests requires invasive sampling. Non-invasive methods such as the H. pylori stool-antigen (HpSA) test may be the best alternative for diagnosis of active infection. However, due to the presence of antigenic-diversity among the strains, various commercial tests have shown some discrepancies in different geographical-a...

Upper gastrointestinal (UGI) bleeding is the most frequently encountered complication of peptic ulcer disease. Helicobacter pylori (Hp) infection and nonsteroidal anti-inflammatory drug (NSAID) administration are two independent risk factors for UGI bleeding. Therefore, testing for and diagnosing Hp infection are essential for every patient with UGI hemorrhage. The presence of the infection is ...

Design, setting, participants & measurements: Three hundred and thirty eight patients were included in the study. They presented to the endoscopy suite at University College Hospital Galway, Ireland (UCHG) with upper gastrointestinal symptoms. The age range is 21-90 years with a median age of 52 years, 62% females, and 24% diabetics. They were divided into 3 groups 18-30 years, 31-60 years, and...

Background: Helicobacter pylori is a gram-negative bacterium that causes chronic gastritis and plays important role in peptic ulcer disease, gastric carcinoma, lymphoma. The main aim objective of the study were to incidence H. pylori. To find efficacy rapid urease test (RUT) histopathological examination biopsy diagnosing organism.
 Methods: This was conducted at saveetha medical college h...

BACKGROUND The purpose of this study is to compare validity of 5 diagnostic tests of helicobacter pylori with each other: stool antigen test, urea breath test (UBT), rapid urease test (RUT), serology and histology. METHODS A total of 94 patients who had indication of endoscopy entered the study. All of the 5 tests were performed for each patient. When the results of at least 2 tests were posi...

Objective: The purpose of this study is to compare the diagnostic performance rapid urease test for H. pylori in endoscopic samples gastric juice compared with same mucosa. Materials and methods: Cross-sectional, comparative prospective concordance tests, carried out patients referred a medical center Bogotá DC, Colombia an esophagogastroduodenoscopy. We included 130 older than 18 years,...
