    Abstract:
    BACKGROUND: Recent studies have suggested that various cytokines may be important players in the development and progression of chronic pancreatitis (CP) and pancreatic adenocarcinoma (PC). AIMS: We studied endothelial dysfunction and subclinical inflammation in patients with newly diagnosed pancreatic adenocarcinoma and CP. METHODS: A total of 45 patients were included in the present investigation, 27 with CP and 18 with PC. In addition, the study included 13 age- and body weight-matched healthy subjects served as controls. In all subjects, plasma adiponectin, TNF-alfa, interleukin 6 (IL-6), interleukin 1beta (IL-1β), E-selectin, thrombomodulin, adhesion molecules ICAM and VCAM, and endothelin-1 were assessed. RESULTS: PC and CP patients as compared with controls had significantly greater plasma adiponectin (13,292 and 12,227 vs 5408 ng/ml; p < 0.0003), TNF-alfa (22.1 and 23.1 vs 13 pg/ml; p < 0.0002), and IL-6 (6.6 and 7.3 vs 3.3 pg/ml; p < 0.0001). Moreover, there was significantly higher concentration of ICAM (931 and 492 vs 290 ng/ml; p < 0.005) and VCAM (1511 and 1080 vs 840 ng/ml; p < 0.01) in PC and CP patients. When PC and CP patients with and without diabetes were considered separately, there was no difference in adiponectin, cytokines, and parameters of endothelial dysfunction. CONCLUSION: In summary, our data indicate that patients with CP and PC express high levels of several cytokines compared with healthy individuals, especially adiponectin, TNF-α and IL-6. Serum TNF-α and ICAM concentrations coordinately increase in advanced CP. Furthermore, especially in PC subjects, elevated markers of endothelial dysfunction are present. This study provides additional evidence that changes in inflammatory cytokine and adhesion molecules in PC and CP are not likely related to endocrine disorders.
