GPT and acute kidney injury: Initial laboratory evaluation was significant for acute kidney injury (creatinine level of 1.9 mg/dL from baseline 0.9-1.0 mg/dL), hyperkalemia (potassium level of 5.4 mEq/L), acute liver injury (aspartate aminotransferase [AST] level of 758 U/L, alanine aminotransferase [ALT] level of 673 U/L), and mixed acidosis (lactic acid level of 4.0 mmol/L) (Table 1).
