Dynamic Changes of Peripheral Blood IL-6,HGF and Ang-2 in Patients with Acute Pancreatitis / 胃肠病学

ABSTRACT

Background:Excessive immune cell activation-inflammatory factor theory is one of the most important pathogenic mechanisms of acute pancreatitis(AP). As the release of inflammatory factors is associated with systemic inflammatory response syndrome,seeking of serum cytokine markers for severity assessment of AP is of great clinical importance. Aims:To determine the dynamic changes of interleukin-6(IL-6),hepatocyte growth factor(HGF),and angiopoietin-2(Ang-2) in peripheral blood of AP patients in the first week after admission,and investigate preliminarily the clinical significance of these markers in AP. Methods:Seventy-two AP patients were prospectively recruited from Apr. 2014 to Oct. 2014 at the First Affiliated Hospital of Soochow University and were assigned into three groupsmild AP(MAP,n = 54),moderately severe AP(MSAP,n = 12)and severe AP(SAP,n = 6)according to the Atlanta classification of AP-2012. Thirty healthy subjects were served as controls. Serum levels of IL-6,HGF and Ang-2 were determined by ELISA on the 1st,3rd and 7th day after admission. Results:In the first week after admission,serum levels of IL-6,HGF and Ang-2 were significantly higher in AP patients than in controls(P 0. 05). Conclusions:IL-6,HGF and Ang-2 might play important roles in the pathogenesis of AP,and being the promising serum markers for severity assessment and dynamic monitoring of AP.
