摘要
目的:心肾联合移植(HKT)的年龄上限仍有争议。本研究评估了年龄≥65岁患者的HKT预后。方法:使用联合器官共享网络(UNOS)对2005年至2021年接受HKT的患者进行识别。患者按移植年龄分层:结果:≥65岁受者的HKT从2005年的5.6%显著增加到2021年的23.7% (p=0.002)。在研究期间的2,022例HKT患者中，372例(18.40%)年龄≥65岁。年龄较大的接受者更可能是男性和白人，在HKT之前需要透析的人较少。在Kaplan-Meier分析中，未调整的90天、1年或5年生存率在队列之间没有差异。这些发现在风险调整后仍然存在，65岁以上人群一年死亡率的调整风险为0.91 (95% CI (0.63-1.29)， p=0.572)。作为一个连续变量，年龄增加与一年死亡率无关(HR 1.01 (95% CI (1.00-1.02)， p=0.236)。≥65岁的患者在出院前需要新发透析的频率更高(11.56% vs. 7.82%， p=0.051)。中风和排异率是相当的。结论:联合HKT在老年受者中增加，高龄≥65岁不应排除HKT。
Outcomes of Combined Heart-Kidney Transplantation in Older Recipients.
Objectives: The upper limit of recipient age for combined heart-kidney transplantation (HKT) remains controversial. This study evaluated the outcomes of HKT in patients aged ≥65 years.
Methods: The United Network of Organ Sharing (UNOS) was used to identify patients undergoing HKT from 2005 to 2021. Patients were stratified by age at transplantation: <65 and ≥ 65 years. The primary outcome was one-year mortality. Secondary outcomes included 90-day and 5-year mortality, postoperative new-onset dialysis, postoperative stroke, acute rejection prior to discharge, and rejection within one-year of HKT. Survival was compared using Kaplan-Meier analysis, and risk adjustment for mortality was performed using Cox proportional hazards modeling.
Results: HKT in recipients aged ≥65 significantly increased from 5.6% of all recipients in 2005 to 23.7% in 2021 (p=0.002). Of 2,022 HKT patients in the study period, 372 (18.40%) were aged ≥65. Older recipients were more likely to be male and white, and fewer required dialysis prior to HKT. There were no differences between cohorts in unadjusted 90-day, 1-year, or 5-year survival in Kaplan-Meier analysis. These findings persisted after risk-adjustment, with an adjusted hazard for one-year mortality for age ≥65 of 0.91 (95% CI (0.63-1.29), p=0.572). As a continuous variable, increasing age was not associated with one-year mortality (HR 1.01 (95% CI (1.00-1.02), p=0.236) per year). Patients aged ≥65 more frequently required new-onset dialysis prior to discharge (11.56% vs. 7.82%, p=0.051). Stroke and rejection rates were comparable.
Conclusion: Combined HKT is increasing in older recipients, and advanced age ≥65 should not preclude HKT.
