An increased risk for gastric cancer in patients with liver cirrhosis has recently been reported. This study was performed in order to determine gastric epithelial cell proliferation in cirrhotic patients and to evaluate the role of congestive gastropathy (CG) and Helicobacter pylori infection in this process. Thirty-six cirrhotic patients and 18 controls were enrolled in the study. All patients underwent endoscopy and three biopsies were performed in the antrum and three in the gastric body. The presence of H. pylori infection was assessed by a rapid urease test and histology. The antral biopsies were used for gastric cell proliferation assessment by an immunohistochemical analysis (Ki-67). There was no significant difference in epithelial cell proliferation between cirrhotics and controls. Gastric proliferation values were higher in patients with H. pylori infection compared with uninfected patients, both in cirrhotic (P = 0.003) and in control groups (P = 0.06). Among the cirrhotic group, we found a progressive increase in gastric cell proliferation values related to the degree of CG, the highest values being observed in cirrhotic patients with severe CG. Moreover, cirrhotics with both severe CG and H. pylori infection had the highest proliferation values when compared with all other subgroups. In conclusion, this study found that: (1) CG significantly affects epithelial cell proliferation in gastric mucosa in cirrhotic patients, (2) H. pylori infection plays a similar role in gastric cell proliferation in both cirrhotic and non-cirrhotic patients, and (3) CG and H. pylori could act synergistically in this process.
