GPT and isolated hyperferritinemia: Initial laboratory tests (Table 1) showed elevated inflammatory markers (C-reactive protein (CRP) 8.52 mg/dL, procalcitonin 2.39 ng/mL), liver cytolysis (alanine aminotransferase (AST) 985 U/L, alanine aminotransferase (ALT) 175 U/L), elevated cholestatic enzymes (gamma-glutamyl transferase (GGT) 344 U/L, ALP 165 U/L), pancytopenia (leukocytes 2.7x109/L, hemoglobin 10.7 g/dL, platelets 67x109/L), hypofibrinogenemia (39 mg/dL), hyperferritinemia (65,865 ng/mL), and elevated soluble CD25 (3,124 U/mL).
