Özet
BackgroundHelicobacter pylori (H. pylori) infection triggers both local inflammation, usually in gastric mucosa, and chronic systemic inflammation. It is assumed that this local and systemic inflammation is caused by extracellular products excreted by H. pylori. The aim of this study was to investigate the possible association between H. pylori infection and a local inflammatory response in the airway by using exhaled breath condensate technique. Materials and MethodsThis study includes 41 H. pylori seropositive patients who have gastric symptoms and 27 healthy control subjects. Pulmonary function tests (PFT), chest X ray, and physical examination were performed in all patients and interleukin-6 (IL-6), 8-isoprostane and nitrotyrosine levels were measured in exhaled breath condensate. ResultsLevels of IL-6 and 8-isoprostane in exhaled breath condensate (EBC) were significantly higher in H. pylori positive patients than control subjects (p < 0.05). Nitrotyrosine levels were also higher in H. pylori positive patients but the difference was not statistically significant. Both groups had similar leukocyte counts, C-reactive protein (CRP) levels and PFT parameters. ConclusionH. pylori infection causes an asymptomatic airway inflammation which can be detected by exhaled breath condensate. The clinical importance of this inflammation remains unclear.
