We are applying to continue participating as an APOL1 Long-term Kidney Transplantation Outcomes Network (APOLLO) Study Clinical Center (CC). The NIH-funded APOLLO Study is performing a national prospective evaluation of deceased donor and recipient APOL1 risk variants in transplants from African American kidney donors to determine effects on outcomes. In addition, APOLLO studies APOL1 genotypes in African American living kidney donors for effects on their post-donation health. Kidney transplants from deceased African American donors typically do not function as long as those from European American deceased donors. Reasons for this are unknown, but retrospective reports suggest that presence of two apolipoprotein L1 (APOL1) gene risk variants in donors may contribute. The APOL1 risk variants are common in populations with recent African ancestry (such as African Americans), where they are strongly associated with end-stage kidney disease. In contrast, they are rare in other population groups. APOL1 genotype data may prove to be clinically useful in those with recent African ancestry in the setting of allocation of deceased donor kidneys for transplantation and assessment of prospective live kidney donors. Genotypic information may provide a more accurate assessment of the likelihood for long-term graft function in donor kidneys, thereby improving matching of donor kidneys with recipients to optimize graft and patient survival. Information may better inform physicians about organ quality prior to decisions on allocation. Information lacking from prior studies will be analyzed, including recipient APOL1 genotypes, kidney histology, viral infection (BK, CMV, SARS-CoV-2), donor specific antibodies, medications, cold ischemia time and acute rejection. Our investigative team, led by two PIs with complementary expertise, recruited the second largest number of eligible kidney transplant recipients in APOLLO to date. Before APOL1 genotyping can be clinically useful, a prospective national study was required to evaluate transplant outcomes from African American kidney donors and recipients of their kidneys based on their genotypes. This was the rationale and setting for the landmark APOLLO Study. Our CC has worked closely with the Wake Forest APOLLO Scientific and Data Research Center (SDRC) and the other participating CCs to recruit and prospectively follow eligible kidney donors and transplant recipients based on the APOLLO Protocol. In Phase 2, we will continue follow-up and measure urine albumin, as well as collect additional biosamples. APOLLO results have the potential to transform the organ allocation and informed consent processes in kidney transplantation, optimize renal allograft survival, reduce discard of good-quality kidneys, and protect the health of living kidney donors.

我们正在申请继续作为 APOL1 长期肾移植成果网络参与 （阿波罗）研究临床中心（CC）。 NIH 资助的 APOLLO 研究正在进行全国前瞻性研究 非洲裔美国人肾脏移植中已故供体和受体 APOL1 风险变异的评估 捐助者确定对结果的影响。此外，APOLLO 研究非裔美国人的 APOL1 基因型 活体肾脏捐赠者对捐赠后健康的影响。已故非裔美国人的肾脏移植 捐赠者的功能通常不如欧洲裔美国已故捐赠者的那么长。这样做的原因 尚不清楚，但回顾性报告表明，存在两个载脂蛋白 L1 (APOL1) 基因的风险 捐助者的变异可能有所贡献。 APOL1 风险变异在最近非洲人的人群中很常见 血统（例如非裔美国人），他们与终末期肾病密切相关。在 相比之下，它们在其他人群中很少见。 APOL1 基因型数据可能被证明在临床上有用 那些最近有非洲血统的人在分配已故捐献肾脏进行移植时 对潜在活体肾脏捐赠者的评估。基因型信息可以提供更准确的评估 供体肾脏实现长期移植功能的可能性，从而改善供体肾脏与 优化移植物和患者的存活率。信息可以更好地让医生了解器官质量 在做出分配决定之前。将分析先前研究中缺乏的信息，包括接受者 APOL1 基因型、肾脏组织学、病毒感染（BK、CMV、SARS-CoV-2）、供体特异性抗体、药物、 冷缺血时间和急性排斥反应。我们的调查团队由两名具有互补专业知识的 PI 领导， 迄今为止，APOLLO 招募了第二多符合条件的肾移植受者。 APOL1 之前 基因分型在临床上可能有用，需要进行一项前瞻性全国研究来评估移植结果 根据基因型，来自非裔美国肾脏捐赠者和肾脏接受者。这是 具有里程碑意义的阿波罗研究的基本原理和背景。我们的 CC 与维克森林大学 APOLLO 密切合作 科学与数据研究中心 (SDRC) 和其他参与的 CC 招募并前瞻性地关注 根据 APOLLO 协议，合格的肾脏捐赠者和移植受者。在第二阶段，我们将继续 跟进并测量尿白蛋白，并收集额外的生物样本。 APOLLO 结果有 改变肾移植器官分配和知情同意流程的潜力，优化 提高同种异体肾移植的成活率，减少优质肾脏的报废，保护活体肾捐献者的健康。
