This review aims to address the critical issue of expanding deceased donor kidney pool and reducing the discard rates of viable kidneys in the United States. It highlights advances in organ preservation techniques and explores strategies for expanding the donor pool by leveraging suboptimal and high-risk nonuse kidneys, including those affected by acute kidney injury (AKI), hepatitis C virus (HCV), and hepatitis B virus (HBV).
Innovations in organ preservation, including hypothermic and normothermic machine perfusion, have demonstrated efficacy in improving outcomes for marginal and extended-criteria kidneys. The integration of normothermic regional perfusion (NRP) for donation after cardiac death (DCD) donors has enhanced organ utilization and graft viability. Additionally, research confirms that kidneys from AKI and HCV-positive donors, when managed with appropriate protocols, yield comparable long-term outcomes to standard transplants. Emerging data on HBV-positive donor kidneys further underscore their potential to safely expand transplant access with targeted antiviral prophylaxis.
Optimizing deceased donor kidney utilization requires a multi-faceted approach, including advancements in preservation technologies, evidence-based decision-making for high-risk organs, and policy innovations. Leveraging these strategies can help address the growing organ shortage, enhance transplant outcomes, and ensure broader access to life-saving kidney transplants.
本综述旨在解决美国扩大已故供体肾脏库以及降低可用肾脏丢弃率这一关键问题。它突出了器官保存技术的进展,并探讨了通过利用次优和高风险弃用肾脏(包括受急性肾损伤(AKI)、丙型肝炎病毒(HCV)和乙型肝炎病毒(HBV)影响的肾脏)来扩大供体库的策略。
器官保存方面的创新,包括低温和常温机器灌注,已证明在改善边缘和扩大标准肾脏的移植结果方面有效。将常温区域灌注(NRP)应用于心死亡后捐赠(DCD)供体,提高了器官利用率和移植物存活率。此外,研究证实,来自急性肾损伤和HCV阳性供体的肾脏,若采用适当方案处理,其长期结果与标准移植相当。关于HBV阳性供体肾脏的新数据进一步强调了通过有针对性的抗病毒预防措施安全扩大移植机会的潜力。
优化已故供体肾脏的利用需要多方面的方法,包括保存技术的进步、对高风险器官的循证决策以及政策创新。利用这些策略有助于解决日益严重的器官短缺问题,提高移植结果,并确保更广泛地获得挽救生命的肾脏移植。
