title: [Gastritis localization and GERD incidence in patients with Cag A(+) and Cag A(-) Helicobacter pylori infection].
abstract: The relationship between Helicobacter pylori (HP) and gastroesophageal reflux disease (GERD) is very complex and still not well understood. However, many issues, even those as basic as whether HP induces or protects against GERD, are still controversial. The gastritis location could play also a role in the induction of GERD. Some investigators suggested that infection by the Cag A strain of HP seems to have a positive association with reflux esophagitis. Therefore, the aim of this study was to investigate the relationship between GERD, gastritis location, HP infection and Cag A positivity.
