摘要:

目的 分析儿童活体肝移植受者术后他克莫司(FK506)的血药浓度及其影响因素。方法回顾性分析天津市第一中心医院 2012 年 6 月至 2013 年 11 月进行的 42 例亲属活体供肝儿童肝移植受者的血药浓度及影响因素等临床资料。采用 SPSS 19.0 统计软件分析儿童活体肝移植受者 FK506 达到有效血药浓度的比例,FK506 血药浓度与剂量的相关性,FK506 血药浓度谷值剂量比(C0/D)与术后时间的相关性,以及儿童活体肝移植受者移植物体重比(GRBW)和肝、肾功能对 FK506 C0/D 的影响。结果 ① 术后第 3 天有 60% 受者达到有效血药浓度,到术后 14 天一直维持在此比例范围内。② 儿童活体肝移植患者术后 1 ~ 14 天内 FK506 血药浓度与给药剂量不呈线性关系。③ 儿童肝移植受者 C0/D 在第 3 天达到平台期并维持在一个比较稳定的水平,术后第 5 天开始下降。④ 对儿童活体肝移植受者的术后肝功能指标天冬氨酸转氨酶(AST)、肾功能指标血尿氮素(BUN)和肌酐(Cr)、GRBW FK506 C0/D 的相关性分析显示,术后 1 ~ 14 天 BUN、Cr、AST、GRBW C0/D 的影响有统计学意义(均 P 0.05)。结论 一定时间范围内,亲属活体供肝儿童肝移植受者的 FK506 用量及血药浓度与术后用药时间呈现一定的变化规律,并且肝肾功能、GRBW 值对术后短期的 C0/D 具有一定影响,从而影响儿童活体肝移植受者术后体内 FK506 的代谢,进而影响药物疗效。 

Abstract:

Objective To analyze blood concentration of tacrolimus and its influencing factors in pediatricliving donor liver transplantation recipients. Methods The general information,clinical manifestation and blood concentration of tacrolimus were analyzed retrospectively in 42 recipients with pediatric living donor liver transplantation from Jan 2012 to Nov 2013. The ratio of recipients who achieved effective blood concentration,the correlation between FK506 concentration and dose,the correlation between FK506 concentration dose ratio (C0/D)and postoperative time,and the effects of graft recipient body weight(GRBW),the effect of liver and kidney function on FK506 C0/D were analyzed by SPSS 19.0. Results ① On the third post operative day,60% of recipients reached effective plasma concentration. And on the 14th day after surgery,the blood concentration of the recipients had maintained within the range of this ratio ;② From the 1st to 14th days,there was no linear relationship between FK506 blood concentration and dosage of administration ;③ C0/D reached plateau on thethird day after surgery and maintained at a relatively stable level,and CO/D decreased on the fifth day after surgery ; ④ There were statistically significant differences between AST,BUN,Cr,and GRBW of recipients and FK506 C0/D by correlation analysis. Conclusion Within a certain time,FK506 dosage and blood concentration showedvariation trends with the postoperative time in the relatives of pediatric living donor liver transplant recipients. AST,BUN,Cr and GRBW value had affected the short-term postoperative C0/D,thus affectiong the metabolism and therapeutic effect of FK506 in pediatric living donor liver transplant recipients.
