Background and Aim: Today ischemic heart diseases are the first reason of death in most societies , and in studies done some testimonies have reported about the role of inflammations and chronic infections in the pathogenesis of coronary heart disease. The aim of this study was to find out if there were any association between Helicobacter- pylori infection and atherosclerosis. Materials and M...
BACKGROUND Rapid urease tests for Helicobacter pylori have a sensitivity of 80% to 90%. Therefore histologic examination of gastric biopsies is recommended as a "backup" diagnostic test in rapid urease test-negative patients. However, noninvasive tests (urea breath test, serology, whole blood antibody tests) may provide a more rapid diagnosis and be less expensive but offer similar accuracy. ...
BACKGROUND The aim of this study was to determine the effect of commonly self-prescribed proton pump inhibitors (PPI) on the results of rapid urease test and histology for the diagnosis of H. pylori infection. METHODS One hundred-nine consecutive patients with dyspeptic symptoms attending the endoscopy suite were enrolled in this study. Antrum biopsy specimens were collected at endoscopy for ...
Helicobacter pylori (H. pylori) remains a prevalent chronic infection in the developing countries. H.pylori is an important agent associated with peptic ulcer disease, chronic gastritis and gastric malignancies. It can be detected by various invasive (rapid urease test and histology) and non-invasive tests (stool antigen test, urea breath test and serology). The aim of this study was to compare...
This study was done to evaluate the prevalence of Helicobacter-like microorganisms in the stomach of feral raccoon dogs (Nyctereutes procyonoides) from the Chonbuk province at the southwest part of Korea and of domestic dogs (Canis familiaris) from Latvia. Mucosal samples were taken from several places of cardiac, fundic, and pyloric gland region of the stomach to detect Helicobacter spp. by em...
OBJECTIVE To assess the accuracy of the determination of Helicobacter pylori infection by a stool immunoassay in patients with upper-gastrointestinal bleeding (UGB) of peptic origin, in comparison with the routine histological study, serology, rapid urease and 13C-breath tests. METHODS Sixty-eight patients with endoscopically proven UGB of peptic origin were included. The presence of H. pylor...
A urease color test fluid medium (U-9) for the detection and identification of T (T-strain) mycoplasmas in clinical material is described which is sensitive and specific for this group of mycoplasmas. The medium was prepared from commercially available components and contained 95% half-strength, tryptic digest broth (pH 5.5), 4% unheated horse serum, 0.05% highest-purity urea, 0.001% sodium phe...
