Current short-term kidney post-transplant survival rates are excellent, but longer-term outcomes have historically been unchanged. This study used data from the national Scientific Registry of Transplant Recipients (SRTR) and evaluated 1-year and 5-year graft survival and half-lives for kidney transplant recipients in the US. All adult (≥18 years) solitary kidney transplants (n = 331,216) from 1995 to 2017 were included in the analysis. Mean age was 49.4 years (SD +/-13.7), 60% male, and 25% Black. The overall (deceased and living donor) adjusted hazard of graft failure steadily decreased from 0.89 (95%CI: 0.88, 0.91) in era 2000-2004 to 0.46 (95%CI: 0.45, 0.47) for era 2014-2017 (1995-1999 as reference). Improvements in adjusted hazards of graft failure were more favorable for Blacks, diabetics and older recipients. Median survival for deceased donor transplants increased from 8.2 years in era 1995-1999 to an estimated 11.7 years in the most recent era. Living kidney donor transplant median survival increased from 12.1 years in 1995-1999 to an estimated 19.2 years for transplants in 2014-2017. In conclusion, these data show continuous improvement in long-term outcomes with more notable improvement among higher-risk subgroups, suggesting a narrowing in the gap for those disadvantaged after transplantation.
目前,短期肾移植后的存活率非常高,但长期结果在历史上一直没有改变。本研究使用了国家移植受者科学登记处(SRTR)的数据,评估了美国 1 年和 5 年的移植物存活率和半衰期。分析纳入了 1995 年至 2017 年所有成人(≥18 岁)单肾移植(n=331216)。平均年龄为 49.4 岁(SD +/-13.7),60%为男性,25%为黑人。总体(已故和活体供者)调整后的移植物失败风险从 2000-2004 年的 0.89(95%CI:0.88,0.91)稳步下降到 2014-2017 年的 0.46(95%CI:0.45,0.47)(1995-1999 年为参考)。对于黑人、糖尿病患者和年龄较大的受者,调整后的移植物失败风险的改善更为有利。已故供体移植的中位存活时间从 1995-1999 年的 8.2 年增加到最近一个时期的估计 11.7 年。活体供肾移植的中位存活时间从 1995-1999 年的 12.1 年增加到 2014-2017 年的估计 19.2 年。总之,这些数据表明长期结果不断改善,高风险亚组的改善更为明显,这表明移植后处于不利地位的人群之间的差距正在缩小。
