Blood gas analysis revealed a pH of 6.9 and a PO2 of 64 mm Hg, which was considered to be metabolic acidosis. An IV infusion of sodium bicarbonate 5% was given. A review of his medical history showed that he had a history of chronic hepatitis B and received telbivudine 600 mg once daily for 11 months and more.

The second day of hospitalisation, he had a peak CK level of 1300 U/L, a CK-MB level of 61 U/L, a ALT level of 512 U/L, and a AST level of 579 U/L. Four days later, his urine volume normalized, renal function gradually returned to within normal ranges. On day 12 of hnspitalisation, his myalgia in the lower extremities markedly improved and his muscle strength recovered to grade Ⅳ ; he had a CK level of 144 U/L, a CK-MB level of 15.1 U/L, a ALT level of 57 U/L, a AST level of 34 U/L, and normal electrolyte levels.
