Strategies to expand numbers of deceased donor kidneys suitable for pediatric recipients are urgently needed to prevent long-term dialysis-associated morbidity and mortality. Donors designated as increased risk of disease transmission (IRD) are infrequently used in pediatric recipients. We examined outcomes of these kidneys in pediatric patients and the potential to increase the donor pool.
The United Network for Organ Sharing (UNOS) database records presence of IRD in all deceased donors since 2004. All pediatric kidney transplant recipients from 2004 to 2017 were identified and stratified by IRD status, and outcomes were examined.
Four hundred seventy-three pediatric kidney transplant recipients received an IRD allograft. IRD donors had lower kidney donor profile index (KDPI); were more likely to be younger, male, and Caucasian; and were more likely to have used drugs. IRD kidneys were more likely to have been biopsied and placed on pulsatile perfusion. Other than an older recipient age, demographic data were not different between groups. Allograft and patient survivals were similar, as were rejection and delayed graft function rates. Compared with adult recipients and adult IRD recipients, pediatric recipients were more likely to have a younger donor, receive a kidney with a lower creatinine, and were less likely to have delayed graft function (p < 0.05). There were no recorded disease transmissions in IRD group.
Patient and allograft survivals are similar in IRD and non-IRD kidneys. High-quality IRD organs used in adults represent a large number of donors with excellent outcomes. IRD allografts have a potential to increase transplant volume and should be considered for pediatric patients.
为了预防长期透析相关发病率和死亡率,急需扩大适合儿科受者的已故供体肾脏数量的策略。被指定为疾病传播风险增加(IRD)的供体在儿科受者中很少使用。我们研究了这些肾脏在儿科患者中的结果以及增加供体库的潜力。
自 2004 年以来,美国器官共享网络(UNOS)数据库记录了所有已故供体中 IRD 的存在。确定了 2004 年至 2017 年所有接受过儿童肾移植的患者,并按 IRD 状态进行分层,然后检查了这些患者的结果。
473 名儿科肾移植受者接受了 IRD 同种异体移植。IRD 供体的肾脏供体评分指数(KDPI)较低;更有可能是年轻、男性和白种人;并且更有可能使用过药物。IRD 肾脏更有可能接受过活检并进行脉动灌注。除了受者年龄较大外,两组之间的人口统计学数据没有差异。同种异体移植物和患者存活率相似,排斥反应和延迟移植物功能发生率也相似。与成年受者和成年 IRD 受者相比,儿科受者更有可能接受年轻的供体,接受肌酐水平较低的肾脏,并且延迟移植物功能的可能性较小(p<0.05)。IRD 组未记录到疾病传播。
IRD 和非-IRD 肾脏的患者和移植物存活率相似。成人中使用的高质量 IRD 器官代表了大量具有出色结果的供体。IRD 同种异体移植物有可能增加移植量,应考虑用于儿科患者。
