Abstract Backgrounds: Helicobacter pylori infection is now recognized as a cause of chronic gastritis, peptic ulcer disease, gastric carcinoma and lymphoma. Several diagnostic methods of H. pylori infection, such as histopathology, culture, rapid urease test, urea breath test, serologic test and polymerase chain reaction (PCR) have been used. This study aimed to compare different diagnostic methods of H. pylori infection and determined the appropriate cut-off value of IgG anti-H. pylori antibody using receiver operating characteristic (ROC) curve. Methods: We compared sensitivities, specificities and efficiencies of histology, CLO test, culture, IgG anti-H. pylori Ab and PCR using the ureC gene in gastric biopsy specimens from 112 H. pylori patients and 140 control group. Results: The sensitivities of histology, CLO test, culture, IgG anti-H. pylori Ab

Abstract Background: There is some evidence linking the infections with common organisms such as Chlamydophila pneumoniae, cytomegalovirus (CMV), Helicobacter pylori and HIV to myocardial infarction (MI). We had performed a serologic study to assess whether C. pneumoniae, CMV, H. pylori and HIV infections are associated with MI. Methods: Serum samples were obtained from 54 cases of acute MI, 33 cases of old MI, and 60 normal controls. C-reactive protein (CRP) as an inflammation marker was measured and antibodies to C. pneumoniae, CMV, H. pylori and HIV were assayed by ELISA. Odds ratios (OR) were calculated against control group. Results: CRP was significantly

Abstract Background: CLSI provides a guideline only for a agar dilution method of testing clarithromycin susceptibility for Helicobacter pylori. This study was to evaluate a disk diffusion method for clarithromycin and amoxicillin. Methods: One hundred and forty clinical isolates of H. pylori isolated from May 2005 to May 2007 were tested by the CLSI agar dilution method and a disk diffusion method using 2μg (2CLR) and 15μg (15CLR) clarithromycin disks and 2μg (2AMX) and 10μg (10AMX) amoxicillin disks.
