Abstract:
Objective To analyze the relationship between plasma copeptin level and prognosis in patients with severe acute pancreatitis(SAP).Methods The clinical data of 48 SAP patients from January 2010 to October 2014 were collected and another 48 patients who accepted healthexamination dur-ing the same period were selected as controls.Difference in plasma copeptin level was compared between groups.The results of APACHEⅡ,Ranson and modified Marshall scores were also collected to evaluate the severity of disease and the existence of MODS.The prevalence of pancreas and peripancreatic tissues effusion,necrosis,pancreas and peripancreatic abscess,pancreatic pseudocyst and mortality of the experi-mental group were recorded to analyze the relationship among plasma copeptin,complications and mortali-ty.Results The plasma level of copeptin of the experimental group was 0.83 ~5.49ng/ml,with a mean of(3.48 ±1.32)ng/ml;while in the control group,it was 0.09 ~1.46ng/ml,with a mean of(0.23 ± 0.06)ng/ml.There was significant difference between the groups(P <0.05).Patient with a high plasma copeptin level may have a higher risk for local complication,MODS and mortality,and there was significant difference between the groups(P <0.05).A ROC curve identified that a plasma copeptin level >4.02 ng/mL predicted in-hospital mortality of patients,with a sensitivity of 72.7%and a specificity of 81.0%(AUC =0.831,95%CI =1.051 ~1.679,P <0.001).Conclusion SAP patients have elevated levels of plasma copeptin,and higher copeptin levels predict high risks of complications and mortality.
