Proinflammatory cytokines and activity of inflammation

Proinflammatory cytokine production (median cytokine values in pg/mg protein (and interquartile range)) in antrum biopsy cultures in Helicobacter pylori-infected and non-infected patients with different activity of gastritis (polymorphonuclear (PMN) cell infiltration). No severe PMN infiltration was found in H. pylori-negative patients. Proinflammatory cytokine secretion was not different in H. pylori-positive gastritis in comparison with H. pylori-negative gastritis (samples matched for histopathological inflammatory activity). Significance for comparison against specimens without inflammatory changes: *P < 0.0001; **P < 0.001; †P < 0.005; ††P < 0.03.
