Serum levels of tumor necrosis factor-alpha, interleukin-6 and interleukin-8 are not increased in dyspeptic patients with Helicobacter pylori-associated gastritis

Abstract

Introduction: Helicobacter pylori ( H. pylori) is a non-invasive microorganism causing intense gastric mucosal inflammatory and immune reaction. H. pylori-induced gastric mucosal cytokine overproduction has been clearly documented previously. The stomach has a large surface area and continuous spill-over of locally produced cytokines into the blood stream is a possibility. There are few and conflicting data on circulatory proinflammatory cytokine levels in patients with H. pylori infection.
