Copeptin is a predictive biomarker of severity in acute pancreatitis

Abstract

Background: Acute pancreatitis remains a common intraabdominal disease with a complex pathophysiology. The overall outcome has improved, but specific treatment remains elusive. The challenge is the early identification and treatment of patients who will develop severe acute pancreatitis. Therefore, the aim of the present study is to investigate plasma levels of copeptin in the initial phase of predicted severe acute pancreatitis. Methods: Between August 2008 and December 2011, 57 patients with acute pancreatitis and 30 healthy individuals were included in the study. Four blood samples, for serum copeptin measurement, were taken from each individual in each group. The first measurement was taken from the admission blood sample. The subsequent 3 samples were taken at 12, 24, and 48 hours after the onset of pain. Results: Copeptin plasma concentrations were significantly higher in patients with acute pancreatitis when compared with healthy controls. Copeptin plasma concentrations in severe pancreatitis patients were significantly higher than in mild pancreatitis patients. Conclusions: Copeptin plasma concentrations were significantly higher in patients with acute pancreatitis when compared with healthy controls. Copeptin plasma concentrations in severe pancreatitis patients were significantly higher than in mild pancreatitis patients. Crown Copyright (C) 2013 Published by Elsevier Inc. All rights reserved.
