GPT and isolated hyperferritinemia: The laboratory data at admission demonstrated bicytopenia (white blood cell count: 1400 /μL; platelet count: 13.4 × 104 /μL), elevated liver enzyme levels (aspartate aminotransferase (AST): 1558 U/L; alanine aminotransferase (ALT): 1007 U/L; lactate dehydrogenase (LDH): 2688 U/L; alkaline phosphatase: 265 U/L; total bilirubin: 0.9 mg/dL), and hyperferritinemia (11,480 ng/ml; normal range: 3.6–114.0 ng/ml).
