肾移植术后长期应用硫氮唑酮对环孢素A用量和肾功能的影响

目的:观察钙通道阻滞药硫氮唑酮(Dil)长期应用对肾移植受者环孢素A(CsA)用量和肾功能的影响。方法:将Dil用于67例服用CsA的肾移植受者,以同期59例肾移植受者为对照,调整2组CsA血药浓度在治疗窗范围内,观察2组用药后36mo内CsA用量以及血肌酐变化。结果:术后第12、24、36moDil组每例CsA用量较对照组同期平均少14353、9656、7817mg;术后12mo内2组血肌酐无显著性差异,以后对照组血肌酐水平上升较快,术后18mo～36mo,Dil组血肌酐水平明显低于对照组同期(P<0.05)。结论:肾移植术后长期应用Dil不仅可明显减少肾移植受者的CsA用量,而且可以改善移植肾功能。

Effects of Long- term Use of Diltiazem on the Dosage of Ciclosporin A and Renal Function of Patients after Renal Transplantation

OBJECTIVE:To investigate the effects of long-term use of calcium channel blocker-Diltiazem(Dil)on the dosage of ciclosporin A and renal function of renal graft recipients.METHODS:Dil was administed in67renal graft recipiˉents,meanwhile who were orally taking CsA with another59renal graft recipients served as controls.The dosages of ciˉclosporin A of2group were adjusted to the level within therapeutic window,then the dosage of CsA and serum creatinine change of the2groups36mo after drug administration were observed.RESULTS:12mo,24mo and36mo after operation,the synchronized cyclosporin A dosages in Dil group were lower than the control group respectively by14353mg,9656mg and7817mg.No significant differences were found in serum creatinine levels between the2groups within the first12mo after operation.Thereafter,the creatinine levels in the control group has a faster increase and the creatinine level in Dil group was significantly lower than that of the control group18mo～36mo after operation(P<0.05).CONCLUSIONS:Long-term use of Dil in renal graft recipients can not only reduce their dosage of CsA but also improve the renal function of their transplanted kidneys.
