background and aims: helicobacter pylori (h. pylori) is the microorganism that infects nearly half of word's population. there are several invasive and non-invasive methods for diagnosis of infection. the main objective of this study was to evaluate antigen of h. pylori in feces with h. pylori stool antigen (hpsa) test and comparison with rapid urease test (rut) in the patients suspected t...

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/AIMS The influence of different media on the validity of the rapid urease test, including accuracy, reaction time and cost-effectiveness is evaluated. METHODOLOGY Biopsies were obtained from the antral and body mucosa of 100 KMUH patients (51 men, 49 women; mean age: 54.0 years, range: 21-79 years old) undergoing gastroendoscopy due to dyspepsia. None of the patients had received a...

BACKGROUND Accuracy of the most frequently used tests for diagnosing Helicobacter pylori infection in patients with upper gastrointestinal bleeding of peptic origin is determined. METHODS Seventy-eight patients with endoscopically-proven upper gastrointestinal bleeding of peptic origin were included. The presence of H. pylori was considered when observed from the histology or, if negative, wh...

A rapid, miniaturized, urea broth test useful for detecting urease activity of yeasts was compared to Christensen urea agar. All urease-producing yeasts tested were positive on both media; however, 60% were reactive in the urea R broth within 30 min, and the remainder were reactive within 4 h. This urea multiwell test may be useful as a rapid screening method for detecting urease-producing yeas...

The aim of the study was to evaluate the suitability of a modified one minute rapid urease test (one day rapid urease test) as a low cost H. pylori detection method. A sample of 205 patients clinically suspected of having H. pylori infection was tested. One day rapid urease test and histology based H. pylori tests (the gold standard) were performed on endoscopic antral biopsies. There were 6 tr...

CONTEXT Multiple diagnostic methods are available for the detection of Helicobacter pylori infection, but at present no single one can be used as the gold standard. OBJECTIVE The aim of this study was to evaluate the diagnostic accuracy of 3 invasive and 2 non-invasive methods for detection of Helicobacter pylori infection in symptomatic children and adolescents. DESIGN Prospective cohort s...

A rapid and sensitive urease test for mycobacteria utilizing a cumulative radiometric technique is described. Definitive results were obtained within a 30-min incubation period. The procedure is simple and economical. Technical time involved is no greater than in conventional procedures.
