CRP and acute pancreatitis: Different biomarkers were used to determine the severity of acute pancreatitis such as C-reactive protein (CRP), serum procalcitonin, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), red cell distribution width (RDW) levels, and the levels of interleukin (IL) 6 (IL-6), IL-8, IL-12, IL-15, and IL-17, polymorphonuclear elastase, and trypsin activation peptide [5].
