Clinical values of MRSI, CRP and FABP4 in the diagnosis and prognosis of acute pancreatitis.

To examine the clinical values of C-reactive protein (CRP), fatty acid-binding protein 4 (FABP4) and magnetic resonance severity index (MRSI) in acute pancreatitis (AP) cases. 70 AP patients and another 70 healthy controls were recruited, and the MRSI score was calculated. Receiver operator characteristic (ROC) curve was used for diagnostic performance analysis. FABP4 levels were elevated in AP patients, and significantly correlated with CRP and MRSI score. Serum FABP4 and MRSI score displayed high diagnostic performance for AP. FABP4, MRSI score and CRP levels were positively correlated with disease severity. MRSI score and FABP4 were independently related to patients' survival, and showed high predictive values. FABP4 may serve as a potential marker for the diagnosis of AP, with the advantages of low cost and high simplicity. The levels of FABP4 and MRSI score can predict the poor survival of the patients.
