美国国立卫生研究院(NIH)联盟报告了HIV+肾移植(KT)受者的良好结局,但尚不清楚是否需要HIV+ KT的经验才能实现这些结局。我们研究了499名HIV+接受者的经验测量和结果之间的关联(SRTR数据2004-2011)。检查的经验指标包括:(1)中心参与NIH联盟;(2)KT经验学习曲线;(3)移植时代(2004-2007 vs. 2008-2011)。在他们的早期经验中,各中心的结局没有差异(前5例HIV+KT)与已进行≥ 6例HIV+ KT的中心相比[GS校正的风险比(aHR):1.05,95%CI:0.68-1.61,p=0.82; PS aHR:0.93; 95%CI:0.56-1.53,p=0.76],参与NIH研究与任何更好的结局无关[GS aHR:1.08,95%CI:0.71-1.65,p=0.71; PS aHR:1.13; 95%CI:0.68-1.89,p=0.63]。移植时间与结局密切相关;与2004-2007年相比,2008-2011年进行的HIV+ KT的移植物丢失风险降低38%[aHR:0.62; 95%CI:0.42-0.92,p=0.02],死亡风险降低41%[aHR:0.59; 95%CI:0.39-0.90,p=0.01]。随着时间的推移,HIV+ KT治疗后的结果有所改善,但中心级经验或联盟参与并不是实现良好结果所必需的,这支持了HIV+ KT在美国的持续扩展。
Excellent outcomes among HIV+ kidney transplant (KT) recipients have been reported by the NIH consortium, but it is unclear if experience with HIV+ KT is required to achieve these outcomes. We studied associations between experience measures and outcomes in 499 HIV+ recipients (SRTR data 2004–2011). Experience measures examined included: (1) center-level participation in the NIH consortium; (2) KT experiential learning curve; and (3) transplant era (2004–2007 vs. 2008–2011). There was no difference in outcomes among centers early in their experience (first 5 HIV+KT) compared to centers having performed ≥ 6 HIV+ KT [GS adjusted hazard ratio (aHR): 1.05, 95%CI: 0.68–1.61, p=0.82; PS aHR: 0.93; 95%CI: 0.56–1.53, p=0.76], and participation in the NIH-study was not associated with any better outcomes [GS aHR: 1.08, 95%CI: 0.71–1.65, p=0.71; PS aHR: 1.13; 95%CI: 0.68–1.89, p=0.63]. Transplant era was strongly associated with outcomes; HIV+ KTs performed in 2008–2011 had 38% lower risk of graft loss [aHR: 0.62; 95%CI: 0.42–0.92, p=0.02] and 41% lower risk of death [aHR: 0.59; 95%CI: 0.39–0.90, p=0.01] than that in 2004–2007. Outcomes after HIV+ KT have improved over time, but center-level experience or consortium participation is not necessary to achieve excellent outcomes, supporting continued expansion of HIV+ KT in the US.
