BACKGROUND
The endoscopic diagnosis of Helicobacter pylori infection in patients with bleeding peptic ulcer is limited by a decreased sensitivity in standard invasive tests, rapid urease test and histology. There is controversy about the convenience of using one, neither, or both diagnostic
BACKGROUND
Peptic ulcer disease is the main cause of upper gastrointestinal bleeding and Helicobacter pylori is its principal etiology. The sensitivity of the diagnostics tests is low for the detection of H. pylori en the setting of bleeding peptic ulcer. In addition there are different results
OBJECTIVE
To assess the efficacy of rapid urease test (RUT) in patients with bleeding ulcers, as well as the effects of visible blood in the stomach and short-term (<24 h) use of standard-dose proton pump inhibitor (PPI) on RUT sensitivity.
BACKGROUND
The sensitivity of RUT in the diagnosis of
BACKGROUND
The sensitivity of invasive diagnostic methods for Helicobacter pylori (H. pylori) infection, particularly of urease rapid test, is decreased in cases of gastroduodenal ulcer and upper gastrointestinal bleeding.
OBJECTIVE
To assess the influence of blood in the stomach or recent bleeding
BACKGROUND
The reliability of the rapid urease test has not been proven in patients with peptic ulcer bleeding. Some studies show bad diagnostic results with the rapid urease test for gastrointestinal bleeding.
OBJECTIVE
To evaluate the efficacy of the rapid urease test in patients with bleeding
BACKGROUND
Previous studies demonstrated that the sensitivity of rapid urease test (RUT) for diagnosis of Helicobacter pylori infection decreased during peptic ulcer bleeding.
OBJECTIVE
We designed this study and tried to find a better method to improve the detection rate of H. pylori infection at
OBJECTIVE
The eradication of Helicobacter pylori (H. pylori) in patients with bleeding peptic ulcer disease (PUD) decreases the rate of ulcer rebleeding. Although all methods for H. pylori diagnosis have been extensively evaluated in uncomplicated PUD the efficacy of the commonly used rapid urease
OBJECTIVE
The validity of the rapid urease (CLO) test to diagnose Helicobacter pylori infection in patients with bleeding ulcers has been questioned. The aim of this paper is to evaluate the validity of the CLO test in comparison with histology in diagnosing H. pylori infection in patients with
OBJECTIVE
A false-negative biopsy urease test (BUT) is common in Helicobacter pylori-associated bleeding peptic ulcers. Although blood in the stomach is thought to interfere with the biopsy urease test, the underlying mechanism remains unknown. This in vitro experiment sought to identify the blood
BACKGROUND
In patients with peptic ulcer bleeding (PUB), diagnostic tests for Helicobacter pylori (H. pylori) infection have low sensitivity. The aim of our study was to investigate the diagnostic yield of dual-priming oligonucleotide-based multiplex (DPO)-PCR using tissue samples from the rapid
BACKGROUND
In peptic ulcer bleeding, the sensitivity of H. pylori tests, in particular of the rapid urease test (RUT), has been reported to be insufficient.
OBJECTIVE
To validate the RUT, serology and the urea breath test were carried out in patients with bleeding peptic ulcers, and to study the
OBJECTIVE
The prevalence of Helicobacter pylori (Hp) has been reported to be lower in patients with bleeding peptic ulcers than in patients with nonbleeding peptic ulcers. This might be due to inaccuracy of the urease-based diagnostic tests when used in patients with bleeding peptic ulcers. The aims
OBJECTIVE
To assess the sensitivity and specificity of polymerase chain reaction (PCR) in detecting Helicobacter pylori (H pylori) infection in patients with bleeding peptic ulcers, and to compare its diagnostic efficacy with other invasive and non-invasive tests.
METHODS
From April to September
