Neutrophil to lymphocyte ratio and platelet to lymphocyte ratio can predict the severity of gallstone pancreatitis

Abstract Background Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) predict severity in various diseases. In this study, we evaluated the value of NLR and PLR as prognostic factors in acute pancreatitis (AP). Methods Patients with AP were prospectively enrolled from March 2014 to September 2016 at Yonsei University Wonju College of Medicine. NLR and PLR were obtained at admission and were compared with other known prognostic scoring systems. Results A total of 243 patients were enrolled with an etiology of gallstone (n = 134) or alcohol (n = 109). NLR (17.7 ± 18.3 vs. 8.8 ± 8.4, P < 0.001) and PLR (344.1 ± 282.6 vs. 177.8 ± 150.1, P < 0.001) were significantly higher in the gallstone AP group than in the alcoholic AP group. For gallstone AP, NLR and PLR were significantly higher in severe AP, whereas high NLR and PLR were not related to severe AP in alcoholic AP. For the gallstone AP group, NLR and PLR demonstrated a predictive value significantly superior to C-reactive protein (CRP), whereas NLR, PLR, and CRP were not significant predictors for alcoholic AP. Conclusion Our study demonstrated that NLR and PLR can predict the severity of AP, but only in gallstone AP.
