One week after discharge, the patient was readmitted due to a hepatitis relapse, evidenced by grade 4 elevations in AST and ALT (922 U/L and 1053 U/L, respectively), grade 3 hyperbilirubinemia (total and direct bilirubin levels of 8.54 and 5.04 mg/dL), and GGT (958 U/L) (Figure 4). Here, GPT is linked to hepatitis A virus infection.
