JASN:肾移植术后抗体诱导治疗效果哪家强?

2017-07-20 xuyihan MedSci原创

大家都知道肾移植受者经常接受抗体诱导治疗,但是之前有关诱导治疗的研究往往因随访时间短和/或缺乏有关并发症的信息而受到局限。而近日在JASN上发表的一篇文章在将器官移植和移植数据网络与医疗保险索赔联系起来之后,比较了3种诱导疗法对肾移植患者的疗效。

大家都知道肾移植受者经常接受抗体诱导治疗,但是之前有关诱导治疗的研究往往因随访时间短和/或缺乏有关并发症的信息而受到局限。而近日在JASN上发表的一篇文章在将器官移植和移植数据网络与医疗保险索赔联系起来之后,比较了3种诱导疗法对肾移植患者的疗效。

该研究采用了在15个临床和人口统计学特征基础上开发的匹配技术,产生了1:1的阿伦单抗-兔抗胸腺细胞球蛋白(rATG)(5330对)和巴利昔单抗-rATG(9378对)受者。继而利用成对的Cox回归来分析主要结果死亡或移植失败。次要终点包括死亡或败血症、死亡或淋巴瘤、死亡或黑色素瘤及1年内的医疗资源利用。

与rATG受者相比,阿仑单抗的患者有更高的死亡风险(风险比[HR],1.14;95%可信区间CI [ 95% ],1.03-1.26;P<0.01)和死亡或移植失败(HR,1.18;95% CI,1.09-1.28;P<0.001)。死亡结果以及死亡或移植失败与老人、非老人亚组和接受口服泼尼松之间通常是一致的。与rATG者相比,巴利昔单抗的患者有增加死亡风险(HR,1.08;95% CI,1.01-1.16;P = 0.03)和死亡或淋巴瘤(HR,1.12;95% CI,1.01-1.23;P = 0.03),但这些差异在亚组分析时并没有体现。阿伦单抗受者的1年资源利用较rATG稍低,但是在巴利昔单与rATG之间并没有不同。

上述的研究数据表明与阿伦单抗和巴利昔单抗相比,rATG发生不良后果的风险较低,包括死亡率。
