GPT and Hypokalemia: Blood tests revealed a considerable increase of activity of aspartate aminotransferase (AST; 2928 U/L; reference interval [RI]: ≤55 U/L), alanine aminotransferase (ALT; 2790 U/L; RI: ≤90 U/L), creatine kinase (CK; 8052 U/L; RI: ≤400 U/L), and lactate dehydrogenase (LDH; 2818 U/L; RI: 161–1051 U/L), increased total bilirubin concentration (6.4 mg/dL; RI: ≤0.6 mg/dL), and hypokalemia (2.8 mmol/L; RI: 4.1–5.6 mmol/L) accompanied by only mild hypernatremia (160 mmol/l; RI: 144–157 mmol/L) and hyperchloremia (127 mmol/L; RI: 102–118 mmol/L).
