摘要

背景:2014 年,国家器官分配系统对已故供肾者进行了一项主要改革,即根据敏感度(即计算出的面板反应性抗体百分比 [CPRA%])采用滑动量表对候选人的优先权进行加权。提高致敏患者的优先权可改善弱势候选者获得移植的公平性。我们试图通过当代美国成年肾移植候选者队列来评估这些权重的效果:方法:我们利用全国移植受者科学登记处,使用多变量逻辑模型评估与致敏相关的因素,并使用考虑竞争风险的累积发生率模型和多变量 Cox 模型评估已故供体移植率:我们对2016年1月至2023年9月期间列入候选名单的270912名成年候选者进行了研究。cPRA%=[80-85]和[90-95]的候选者6年累计死亡供体移植发生率分别为48%和53%,而cPRA%=[0-20]的候选者为37%。在多变量模型中,cPRA%高的候选者接受死亡供体移植的调整后危险度最高。高 cPRA% 与调整后的死亡供体移植率之间的关系因国家地区、性别、种族/民族、之前的透析时间和血型的不同而不同:结果表明,针对高度敏感候选者的加权算法可能会过度夸大优先顺序的必要性,并导致更高的移植率。研究结果表明,需要重新校准分配的优先权重,以促进潜在肾移植候选者获得移植的整体公平性。然而,优先权点还应考虑到在获得供体方面处于不利地位的候选者亚群。

期刊介绍: The Clinical Journal of the American Society of Nephrology strives to establish itself as the foremost authority in communicating and influencing advances in clinical nephrology by (1) swiftly and effectively disseminating pivotal developments in clinical and translational research in nephrology, encompassing innovations in research methods and care delivery; (2) providing context for these advances in relation to future research directions and patient care; and (3) becoming a key voice on issues with potential implications for the clinical practice of nephrology, particularly within the United States. Original manuscript topics cover a range of areas, including Acid/Base and Electrolyte Disorders, Acute Kidney Injury and ICU Nephrology, Chronic Kidney Disease, Clinical Nephrology, Cystic Kidney Disease, Diabetes and the Kidney, Genetics, Geriatric and Palliative Nephrology, Glomerular and Tubulointerstitial Diseases, Hypertension, Maintenance Dialysis, Mineral Metabolism, Nephrolithiasis, and Transplantation.
