Gastric inflammation is a significant contributor to the disease process associated with Helicobacter pylori infection. It appears that both bacterial genes and differential host responses make interrelated contributions to gastritis and disease outcome after H. pylori infection. While the cag pathogenicity island (PAI) continues to be a focus for much of this investigation on the bacterial side, other bacterial genes/proteins are certainly important as well. On the host cell side, significant progress is being made defining the eucaryotic signaling cascades induced after host cells interact with H. pylori . The role of host cell cytokines, gastric acid, and mast cells is also being actively studied. Prospects for control of H. pylori associated disease continue to include vaccination. The mechanism(s) for vaccine‐mediated control of H. pylori infection and disease remain ill‐defined but recent evidence from animal models suggests that the inflammatory response may be involved. Manipulating the host response to H. pylori infection in humans to take advantage of the possible beneficial effects of inflammation, while minimizing its detrimental effects is a significant challenge for the future.
