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...

Detection of helicobacter pylori (H. pylori) by invasive methods is costy and unpleasant for patients and is not free form complication ,thus in our study we evaluated an enzyme linked immunosorbent assay (ELISA) for measurement of H. pylori specific IgG in saliva in comparison with biopsy urease test and serum IgG.from 100 patients consult gastrointestinal in Najaf Hospitals during the period ...

background and objectives: tuberculosis (tb) is a major problem in the world. treatment and control of tb needs detection of the mycobacterium tuberculosis (mt) in the proper samples. while smear doesn’t have enough sensitivity, culture and pcr are expensive, time consuming and unavailable in many centers. recent development of a rapid tb antigen detection test (prtbk) at pasteur institute of i...

BACKGROUND Helicobacter pylori infection is likely acquired in childhood. Helicobacter pylori is recognized as a cause of gastritis and peptic ulcer. OBJECTIVE To investigate some noninvasive tests, particularly H pylori fecal antigen, for the diagnosis of H pylori infection in comparison with the gold-standard invasive test, esophagogastroduodenoscopy with biopsy. METHODS We studied 250 pa...

With black soil (Pachic Udic Argiboroll) of Northeastern China as the test object, an incubation test was conducted to investigate the effects of urease inhibitors, hydroquinone (HQ), phenyl phosphorodiamidate (PPD) and N-(n-Butyl) thiophosphoric triamide (NBPT), on the kinetic characteristics of soil urease under normal moisture and waterlogged conditions, aimed to study the changes of catalyt...

Campylobacter pyloridis is strongly associated with the presence of histological gastritis,1 2 but its role in the aetiology of peptic ulcer disease and non-ulcer dyspepsia has yet to be determined. Its detection in antral mucosal biopsy specimens usually entails histo-logical or microbiological methods that may require several days for a result. In a previous study3 we found that direct examin...

BACKGROUND The best sites for biopsy-based tests to evaluate H. pylori infection in gastritis with atrophy are not well known. This study aimed to evaluate the site and sensitivity of biopsy-based tests in terms of degree of gastritis with atrophy. METHODS One hundred and sixty-four (164) uninvestigated dyspepsia patients were enrolled. Biopsy-based tests (i.e., culture, histology Giemsa stai...
