(Wiley, 2007-03-01) Baskan, E. B.; Yılmaz, E.; Saricaoglu, H.; Alkan, G.; Ercan, I.; Mistik, R.; Adim, S. B.; Goral, G.; Dilek, K.; Tunali, S.; 0000-0002-3894-1231; 0000-0002-2382-290X; AAH-1388-2021
Background: There is disagreement in the current evidence for viral aetiologies in the pathogenesis of Behcet's disease (BD).Objectives: To investigate the presence of B19 DNA in skin lesions of patients with BD, compare with the skin of healthy controls and evaluate its role in the pathogenesis.Methods: In total, 40 patients diagnosed with BD according to the criteria proposed by the International Study Group for Behcet's Disease and routinely followed up at our centre were enrolled into the study. All the patients selected were in the active phase of disease. Skin and blood samples of patients with BD and of the healthy volunteers were examined for B19 serology, histopathology and genome expression.Results: The quantity of B19 DNA in nonulcerative BD lesions of was significantly different from ulcerative lesions in the study group and from the skin of the healthy controls (P < 0.01). For the nonulcerative lesions, real-time PCR analysis for B19 DNA was found to be 64% sensitive (95% CI 42.5-82.0) and 85% specific (95% CI 62.1-96.6) with a cut-off value of > 154 IU/mL (P < 0.001).Conclusions: To the best of our knowledge, this is the first study that provides evidence for a possible causal link between BD and parvovirus B19, and our data suggest the presence of the virus, particularly in intact, nonulcerative skin lesions of BD. Limitations to this study include the limited number of participants, and the fact that the exact source of B19 DNA was undetected.

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.
