The association between CagA status and the development of esophagitis after the eradication of Helicobacter pylori.
The American Journal of Medicine(2001)
Abstract
BACKGROUND: Strains of Helicobacter pylori with the cytotoxine-associated gene A (cagA) are linked to severe forms of gastroduodenal disease. Although eradication of H. pylori may predispose to the development of reflux esophagitis, the effects of CagA status on risk of esophagitis after successful H. pylori treatment are not known.
