Depleting induction therapy is recommended in sensitized kidney transplant recipients (KTRs), though the detrimental effect of nondonor-specific anti-HLA antibodies is not undeniable. We compared the efficacy and safety of basiliximab and rabbit anti-thymocyte globulin (rATG) in sensitized KTRs without pre-existing donor-specific antibodies (DSAs). This monocentric retrospective study involved all sensitized KTR adults without pre-existing DSAs (n = 218) who underwent transplantation after June 2007. Patients with basiliximab and rATG therapy were compared for risk of biopsy-proven acute rejection (BPAR) and a composite endpoint (BPAR, graft loss and death) by univariate and multivariate analysis. Patients with basiliximab (n = 60) had lower mean calculated panel reactive antibody than those with rATG (n = 158; 23.7 ± 24.2 vs. 63.8 ± 32.3, P < 0.0001) and more often received a first graft (88% vs. 54%, P < 0.0001) and a transplant from a living donor (13% vs. 2%, P = 0.002). Risks of BPAR and of reaching the composite endpoint were greater with basiliximab than rATG [HR = 3.63 (1.70-7.77), P = 0.0009 and HR = 1.60 (0.99-2.59), P = 0.050, respectively]. Several adjustments did not change those risks [BPAR: 3.36 (1.23-9.16), P = 0.018; composite endpoint: 1.83 (0.99-3.39), P = 0.053]. Infections and malignancies were similar in both groups. rATG remains the first-line treatment in sensitized KTR, even in the absence of pre-existing DSAs.
在致敏肾移植受者(KTR)中,推荐使用耗竭诱导治疗,但非供体特异性抗 HLA 抗体的不良影响并非不可否认。我们比较了 basiliximab 和兔抗胸腺细胞球蛋白(rATG)在无预先存在的供体特异性抗体(DSA)的致敏 KTR 中的疗效和安全性。这项单中心回顾性研究包括所有在 2007 年 6 月后接受移植的无预先存在的 DSA 的成年致敏 KTR(n = 218)。通过单因素和多因素分析比较 basiliximab 治疗和 rATG 治疗的患者发生活检证实的急性排斥反应(BPAR)和复合终点(BPAR、移植物丢失和死亡)的风险。接受 basiliximab(n = 60)治疗的患者的平均计算面板反应抗体低于接受 rATG(n = 158)治疗的患者(23.7 ± 24.2 比 63.8 ± 32.3,P < 0.0001),并且更常接受首次移植(88%比 54%,P < 0.0001)和来自活体供者的移植(13%比 2%,P = 0.002)。与 rATG 相比, basiliximab 治疗的 BPAR 和达到复合终点的风险更高[HR = 3.63(1.70-7.77),P = 0.0009 和 HR = 1.60(0.99-2.59),P = 0.050]。进行了几项调整,但并未改变这些风险[BPAR:3.36(1.23-9.16),P = 0.018;复合终点:1.83(0.99-3.39),P = 0.053]。两组患者的感染和恶性肿瘤发生率相似。rATG 仍然是致敏 KTR 的一线治疗方法,即使在没有预先存在的 DSA 的情况下也是如此。
