Helicobacter pylori infection is associated with the development of atrophic gastritis and increased gastric epithelial proliferation that is important in developing gastric carcinoma. Some countries with a high prevalence of H. pylori infection have high gastric cancer rates, whereas in others these rates are low. Several theories have been advanced to explain this phenomenon. One of these explanations is that the concurrent parasitic infection that is common in the African population might alter the immune response to H. pylori infection and reduce the incidence of atrophic gastritis. The aim of the present study was to assess whether concurrent Schistosoma mansoni infection with H. pylori has an effect on gastric mucosal injury in view of cell proliferation, apoptosis, pathological changes, nitric oxide (NO), oxyradicals and antioxidant capacity status.
