BACKGROUND: Helicobacter pylori (H. pylori) infection causes inflammation and increases the risk of developing peptic ulcer disease (PUD); however, the exact molecular mechanisms of PUD development remain unclear. The aim of this study was to investigate the expression of CCL18, CCL28, and CXCL13 in H. pylori-positive subjects in comparison with H. pylori-negative subjects, and to determine its association with different clinical outcomes and virulence factors.
METHODS: In total, 55 H. pylori-positive subjects with gastritis, 47 H. pylori-positive subjects with PUD, and 48 H. pylori-negative subjects were enrolled in this study. CCL18, CCL28, and CXCL13 expression were determined using real time polymerase chain reaction (PCR). The virulence factors of H. pylori such as cytotoxin-associated gene A (cagA), outer inflammatory protein A (oipA), blood group antigen-binding adhesin (babA), and vacuolating cytotoxin A (VacA) genes were evaluated using PCR.
RESULTS: CCL18, CCL28, and CXCL13 expression in H. pylori-positive subjects were significantly higher than H. pylori-negative subjects. CCL18 and CXCL13 expression in H. pylori-positive subjects with oipA+ and babA2+were significantly higher than H. pylori-positive subjects with oipA¯ and babA2¯. CCL18 and CXCL13 expression were found to be significantly elevated in H. pylori-positive subjects with gastritis compared with H. pylori-positive subjects with PUD. CCL28 expression was significantly higher in H. pylori-positive subjects with PUD compared with H. pylori-positive subjects with gastritis.
CONCLUSIONS: The increased of CCL18 and CXCL13 may be involved in the pathogenesis of H. pylori-associated gastritis, while the increased of CCL28 may be involved in the pathogenesis of H. pylori-associated PUD.
