抗淋巴细胞制剂诱导治疗对肾移植后人、肾长期存活的影响

目的 探讨抗淋巴细胞制剂诱导治疗对肾移植后人、肾长期存活的影响.方法 271例首次接受尸体肾移植的受者,其中使用抗胸腺细胞球蛋白诱导治疗者110例(ATG组),使用巴利昔单抗诱导治疗者88例(Bax组),未接受诱导治疗者73例(对照组).所有受者术后采用他克莫司+吗替麦考酚酯+皮质激素的三联免疫抑制方案,并应用更昔洛韦预防CMV感染.术后对所有受者进行了1~5年的随访,观察和比较各组术后6个月内的并发症发生情况,以及术后1、3、5年的人、肾存活率.结果 ATG组、Bax组和对照组术后6个月AR的发生率分别为9.1 %(10/110)、10.2 %(9/88)和17.8 %(13/73),ATG组和Bax组间AR发生率的差异无统计学意义(P＞0.05),但均显著低于对照组(P＜0.05).3组间移植肾功能恢复延迟、CMV感染及非CMV感染等发生率的比较,差异均无统计学意义(P＞0.05).ATG组和Bax组术后1、3、5年移植肾存活率分别为95.5 %、90.9 %、87.3 %和93.2 %、87.5 %、83.8 %,均显著高于对照组的87.7 %、80.8 %、75.3 %(P＜0.05).结论 应用抗淋巴细胞制剂进行免疫诱导治疗可显著降低肾移植术后早期AR的发生率,并显著改善移植肾的长期存活率.

Abstract：

Objective To explore the impact of induction therapy with anti-lymphocyte agents on long-term survival of kidney transplantation.Methods 271 recipients of first cadaveric kidney transplants were treated with tacrolimus,mycophenolate mofetil and prednisone.110 patients of them received induction therapy with anti-thymocyte globulin(ATG group),88 patients received Basiliximab(Bax group),and the remaining 73 patients did not receive induction therapy(control group).The data of AR,DGF,CMV infection,and 1- 3- 5-year patient/allograft survival rate in three groups were retrospectively during a follow-up period of 1 to 5 years postoperatively.Results Within 6 months after operation,the incidence of AR in control group,ATG group and Bax group was 17.8 %(13/73),9.1 %(10/110)and 10.2 %(9/88)respectively.The incidence of AR in ATG group and Bax group was significantly lower than in control group (P<0.05).There was no significant difference in incidence of DGF and CMV infection among three groups.The 1-,3- and 5-year allograft survival rate postoperation in ATG group and Bax group was 95.5 %,90.9 %,87.3 % and 93.2 %,87.5 %,83.8 % respectively,which was significantly higher than in control group(87.7 %,80.8 % and 75.3 %,P<0.05).Conclusion Induction therapy with anti-lymphocyte agents may reduce the early incidence of AR and prolong long-term allograft survival significantly.
