Abstract

Introduction: Helicobacter pylori and Epstein-Barr virus (EBV) infection have recently 23 been shown to be associated with gastric diseases. Polymorphisms in genes encoding 24 cytokines such as interleukin 10 (IL-10) and interleukin 1 Receptor (IL-1RN) influence 25 cytokine secretion levels and appear to contribute to the risk of developing gastroduodenal 26 diseases. 27 To our knowledge, this is the first preliminary study to address the association of 28 coinfection with H. pylori and EBV and their correlation with genetic predisposition in the 29 development of gastric diseases. 30 Methods: Gastric biopsy samples of 96 patients with different gastric diseases were used. 31 Results: Our results showed that the rate of co-infection was higher in patients with 32 gastric cancer than in patients with normal gastric mucosa, active chronic gastritis and 33 MALT lymphoma. As regards the characterization of H. pilory strains, the 34 polymorphism s1m1i1 of vacA gene was more frequent in patients with MALT 35 Lymphoma in comparison to others, while the polymorphism s2m2i2 was most 36 frequent in patients with normal gastric mucosa. In addition, patients who tested 37 positivefor the cagA gene were more frequently those affected with gastric cancer than 38 those with inactive chronic gastritis. Similarly, the patients with oipA gene ON were more 39 frequently those with gastric cancer than those with inactive chronic gastritis. 40 Conclusion: According to our analysis, there was no correlation between coinfection 41 and polymorphisms in genes encoding IL-10 and IL-1RN. We conclude that various 42 factors can be involved in the development of gastric diseases.
