Despite data demonstrating increased utilization of kidneys from hepatitis C virus (HCV)-infected donors, it is unknown whether this is due to an increase in the donor pool or improved organ utilization and whether data from early pilot trials were temporally associated with changes in organ utilization. We used data from the Organ Procurement and Transplantation Network on all kidney donors and recipients of kidney transplants from January 1, 2015, to March 31, 2022 to evaluate temporal changes using joinpoint regression. Our primary analyses compared donors on the basis of their HCV viremic status (HCV-infected vs HCV-negative). Kidney utilization changes were assessed by evaluating the kidney discard rate and kidneys transplanted per donor. A total of 81 833 kidney donors were included in the analysis. There was a statistically significant decrease in the discard rates of HCV-infected kidney donors from 40% to just over 20% over a 1-year period, with a concurrent increase in kidneys transplanted per donor. This increased utilization occurred in tandem with the publication of pilot trials involving HCV-infected kidney donors in HCV-negative recipients rather than an increase in the donor pool. Ongoing clinical trials may strengthen existing data, which could result in this practice becoming the accepted standard of care.
尽管有数据表明,来自丙型肝炎病毒 (HCV) 感染供体的肾脏利用率增加,但尚不清楚这是由于供体库的增加还是器官利用率的提高,以及早期试点试验的数据是否与器官利用率的变化有关。我们使用了 2015 年 1 月 1 日至 2022 年 3 月 31 日期间,器官获取与移植网络(Organ Procurement and Transplantation Network)的所有肾脏供体和接受肾脏移植者的数据,利用联合点回归法进行时间变化评估。我们的主要分析是基于供体的 HCV 病毒血症状态(HCV 感染与 HCV 阴性)进行比较。通过评估肾脏废弃率和每位供体移植的肾脏数量来评估肾脏利用率的变化。共纳入 81833 名肾脏供体进行分析。在 1 年内,HCV 感染供体的肾脏废弃率从 40%显著下降至略高于 20%,同时每位供体移植的肾脏数量增加。这种利用率的增加与涉及 HCV 阴性受者中 HCV 感染肾脏供体的试点试验的发表同时发生,而不是供体库的增加。正在进行的临床试验可能会加强现有数据,这可能导致这种做法成为公认的护理标准。
