CRP and Hemophagocytosis: Many patients had signs of hemophagocytosis: ferritin (n = 69/90, 76.7%); high levels of liver enzymes: ALT (n = 85/164, 52.8%), AST (n = 101/148, 68.2%), LDH (n = 56/94, 59.6%), D-dimer (n = 120/125, 96.0%), hypoalbuminemia (n = 115/182, 81.0%), and hypoproteinemia (n = 102/126, 81.0%); and signs of inflammation—elevation of ESR (n = 150, 90.9%) and CRP (n = 153/157, 97.5%).
