Helicobacter pylori-Induced Immunological Responses in Patients with Duodenal Ulcer and in Patients with Cardiomyopathies

Abstract: The interaction between the bacteria and the host is a key factor determining the clinical consequences of H. pylori infection. The immune system plays an important role in either promoting or preventing the disease. The mucosal production of TNF-alpha, IL-6, IL-8 and IL-10 and the CagA status were investigated in H. pylori-positive patients with duodenal ulcer (DU). The concentrations of these cytokines in gastric antral mucosal specimens from patients infected with H. pylori (n = 40) were determined by ELISA… Show more

“…Pathogen binding to class II majorhistocompatibility-complex (MHC) on the surface of gastric epithelial cells can induce apoptosis (Fan et al, 2000). As noted above, translocation of CagA into the gastric epithelial cells leads to higher levels of proinflammatory cytokines such as TNF-a, IL-6, IL-10, and most importantly, IL-8 (Klausz et al, 2004;Kim et al, 2006). The VacA protein interacts with macrophages, B-and T-lymphocytes.…”

“…Accumulation of profuse amounts of ammonia in the colon is toxic and could lead to pelvic congestion. In addition, the increased mucosal production of inflammatory cytokines of H. pylori could play an integral role in the pathogenesis of ED [18,19].…”

“…The association of H. pylori with autoimmune disorders and chronic idiopathic dermatitis was sufficiently reported [10]. The role played by the increased mucosal production of inflammatory mediators (cytokines) induced by H. pylori was also clearly illustrated [11,12].…”
