In addition to gastroduodenal diseases, Helicobacter pylori infection has been associated with extradigestive diseases, including coronary heart disease. Different studies have failed to demonstrate a clear association. The aim of this work was to carry out a meta-analysis of these studies' results, with a special emphasis on heterogeneity.

Since the advent of sensitive diagnostic blood tests for the detection of antibody to hepatitis C virus (HCV) in donors, there has been a large decline in the incidence of transfusion-related hepatitis. Globally, the infection has an estimated prevalence of 3%, with a prevailing 1% in Europe while varying geographically within a North-South gradient,(More)
Helicobacter pylori (H. pylori) and Epstein-Barr virus (EBV) are 2 common and widely disseminated agents throughout the world. H. pylori has been classified, by the International Agency for Research on Cancer conference, as a class I carcinogen, i.e. undoubted cause of gastric cancer. However, this infection does not explain all the epidemiological and(More)
Helicobacter pylori (H. pylori) infection spreads from person-to-person, however the precise mode of transmission (oral-oral, fecal-oral or gastro-gastric) is hitherto not known. Gaining understanding into the spread of the bacterium might be useful in identifying high-risk populations, especially in areas that have high rates of gastric malignancies or(More)
Gastric carcinogenesis involves a slow but continuous, stepwise evolution from superficial gastritis to glandular atrophy, metaplasia, dysplasia, and finally, to adenocarcinoma. In 1994, the International Agency for Research on Cancer defined Helicobacter pylori (H. pylori) as a group I carcinogen. Evidence supporting a causal association has been(More)
Clostridium difficile-associated disease (CDAD) ranges in severity from mild diarrhoea to fulminant colitis and death. Antimicrobial use is the primary risk factor for development of CDAD. C. difficile typically affects older or severely ill patients, hospitalized or residents in long-term-care facilities. We report a case of CDAD in a 77-year-old woman(More)
BACKGROUND AND AIM The problem of antibiotic resistance is worldwide and affects many types of pathogens. This phenomenon has been growing for decades and nowadays we are faced with a wide range of worrisome pathogens that are becoming resistant and many pathogens that may soon be untreatable. The aim of this study was to determine the resistance and(More)
