    Background: Adiponectin (ApN) is a 244-amino acid protein mainly secreted from the adipose tissue and involved in various physiological functions. ApN exerts its metabolic effects by binding to two major receptors: adiponectin receptor-1 (Adipo-R1) and adiponectin receptor-2 (Adipo-R2). Recent studies have reported ApN's involvement in the progression of cancer. However, there are no studies evaluating the relationship between Adipo-R1/R2 expression and gastric intestinal metaplasia (IM), which is a predisposing factor in gastric cancer (GC) development, and Helicobacter pylori H. pylori infection. Aims: In this study we aimed to investigate the relationship between the Adipo-R1/-R2 expression and H. pylori infection in patients with GC and gastric IM. Materials and Methods: Forty patients that underwent gastric resection and 56 patients that developed gastric IM were included in the study. The Adipo-R1/-R2 expression and the presence of H. pylori were examined immunohistochemically. The univariate analyses showed that the expression of Adipo-R1/-R2 in GC patients was significantly lower compared to both complete metaplasia (CM) and incomplete metaplasia (ICM) patients (p <0.0001 for both). Results: According to multiple multinomial logistic regression analysis, Adipo-R1/-R2 expression in the CM group was significantly higher than in the GC group (p = 0.05, p = 0.014, respectively). Moreover, Adipo-R1/-R2 expression was significantly higher in ICM group compared to the GC group (p=0.012, p=0.045, respectively). However, in both analyses no significant difference was determined in terms of H. pylori positivity between the groups.Conclusion: The resulting data suggests that ApN plays a role in GC processes via Adipo-R1/-R2 receptors.
