1例38岁女性尿毒症患者行肾移植术后第5天予他克莫司1 mg口服、1次/12 h，服药第15天患者他克莫司血药谷浓度为9.8 μg/L。第17天患者出现腹痛，恶心，呕吐；腹部CT示胰腺体积增大，边缘不规则，胰周及腹腔可见明显渗出。实验室检查示血淀粉酶430 U/L，脂肪酶231 U/L。考虑为急性胰腺炎，可能与他克莫司有关。停用他克莫司，改用环孢素A 100 mg口服、1次/12 h，同时予禁食、胃肠减压、降脂、抑酸、抗感染及肠外营养等对症支持治疗。治疗3 d后上述症状缓解。19 d后血淀粉酶173 U/L，脂肪酶51 U/L；腹部CT示胰腺轮廓较前清晰，周围渗出明显减少。“,”A 38-year-old female patient with uraemia received tacrolimus 1 mg orally twice daily after kidney transplantation. The serum trough concentration of tacrolimus was 9.8 μg/L on the 15th day. On the 17th day, the patient developed abdominal pain, nausea, and vomiting. The abdominal CT showed that the volume of pancreas increased, the edge was irregular, and obvious exudation appeared around the pancreas and in the abdominal cavity. Laboratory tests showed blood amylase 430 U/L and lipase 231 U/L.The acute pancreatitis related to tacrolimus was considered. Tacrolimus was stopped and replaced by cyclosporine A 100 mg orally twice daily. Meanwhile, symptomatic and supportive treatments such as fasting, gastrointestinal decompression, lipid-lowering, acid inhibition, anti-infection, and parenteral nutrition were given. Three days later, the above symptoms were relieved. Nineteen days later, laboratory tests showed blood amylase 173 U/L and lipase 51 U/L; abdominal CT showed that the outline of the pancreas was clearer than before, and the exudation around was significantly reduced.
