1例51岁女性患者因甲状腺功能亢进症服用甲巯咪唑5mg,1次/d,10d后出现皮肤瘙痒、恶心、呕吐、大便呈灰白色,第15天停用甲巯咪唑。实验室检查示丙氨酸转氨酶(ALT)184U/L,天冬氨酸转氨酶(AST)115U/L,总胆红素(TBil)41.6μmol/L,直接胆红素(DBil)28.6μmol/L,碱性磷酸酶(ALP)342U/L。考虑为药物所致胆汁淤积型肝损伤。遂静脉滴注脱氧核苷酸钠注射液150mg,1次/d和注射用复合辅酶400U,2次/d。保肝治疗第7天ALT150U/L,AST67U/L,TBil28.7μmol/L,DBIL19.1μmol/L;第13天A坍93U/L,AST57U/L;第28天ALT62U/L,AST45U/L。TBil11.1μmol/L,DBil5.8μmol/L。
A 51-year-old woman with hyperthyroidism was given thiamazole 5 mg once daily. Ten days later, the patient presented itchiness, nausea, vomiting, and gray excrements. On day 15, the thiamazole was withdrawn. Laboratory examination revealed the following levels: alanine aminotransferase (ALT) 184 U/L, aspartate aminotransferase (AST) 115 U/L, total biliruhin(TBil) 41.6 μmol/L, and direct bilirubin (DBil) 28.6 μmol/L. The patient was considered as cholestatic liver injury. She was given an IV infusion of sodium deoxyribonucleotide injection 150 mg once daily and coenzyme complex for injection 400 U twice daily. On day 7 of liver-protective treatment, laboratory examination showed the following levels: ALT 150 U/L,AST 67 U/L, TBil 28.7 μmol/L, and DBil 19.1 μmol/L. On day 13, the levels of ALT and AST were 93 U/L,and 57 U/L, respectively. On day 28, the levels of ALT, AST,TBil and DBil were 62 U/L, 45 U/L, 11.1 μmoL/L, and 5.8 μmol/L, respectively.
