Laboratory testing showed the following results:white blood cell count 14. 1 × 109/L,eosinophil count 1 100 × 106/L,alanine aminotransferase 130 U/L,aspartate aminotransferase 93 U/L,total bilirubin 160. 5 μmol/L,direct bilirubin 144. 3 μmol/L, blood urea nitrogen 39. 2 mmol/L,serum creatinine 628 μmol/L,uric acid 508 μmol/L,and prothrombin activity 61%. Allopurinol-induced hypersensitivity syndrome, drug induced liver injury and acute exacerbation of chronic renal insufficiency were diagnosed. Allopurinol was discontinued and he was given IV infusions of compound glycyrrhizin,glutathione,vitamin C,vitamin B6 ,imipenem and cilastatin sodium, and human albumin.
