“Background Helicobacter pylori (H. pylori) causes a spectrum of gastric diseases ranging from mild to severe gastritis and peptic ulcers to gastric cancer [1]. During early stages of infection, H. pylori adheres to the gastric epithelial cells in the gastric pit, leading to induction of chemokines and cytokines. These proinflammatory mediators induce the infiltration of neutrophils and lymphocytes.
