Abstract

Introduction

The number of patients on heart transplant waitlists is growing globally, with an insufficient number of organ offers to meet this growing demand. To help improve patient outcomes, in the United Kingdom (UK), orthotopic cardiac transplantation (OCTx) can occur using hearts donated following donor brain death (DBD) or donor circulatory death (DCD). The aim of this paper was to compare outcomes between groups of DBD and DCD OCTx patients at Harefield Hospital.

Methods

44 DCD patients (transplanted between 2012 and 2023) were matched (with outcomes blinded, by age and gender) with 33 DBD patients (transplanted between 2015 and 2023). Short-term outcomes (up until 1-year posttransplants, including outcomes such as primary graft dysfunction [PGD] and length of intensive care unit [ICU] stay) and midterm outcomes (up until 5 years posttransplant, including outcomes such as all-cause-mortality, episodes of rejection and graft left ventricular function) were assessed.

Results

Overall, no significant differences were noted with regard to baseline characteristics, and outcome measures (both short and mid-term outcomes) between the matched DCD and DBD cohorts. Event-free survival with regard to all-cause mortality also remained not significantly different between both groups (log-rank p < 0.756).

Conclusion

In conclusion, our single-center UK data did not demonstrate any differences in outcomes between DCD and DBD OCTx patients. We add to growing literature that would support DCD organ use in heart transplantation, in an effort to reduce growing organ demand worldwide.

比较脑死亡和循环死亡原位心脏移植受者捐献的中期结果——一项英国单中心回顾性研究

全球心脏移植等待名单上的患者数量正在增长，器官供应不足以满足这一不断增长的需求。为了帮助改善患者的预后，在英国（UK），可以使用供体脑死亡（DBD）或供体循环死亡（DCD）后捐赠的心脏进行原位心脏移植（OCTx）。本文的目的是比较Harefield医院DBD和DCD OCTx患者组间的结果。方法将44例DCD患者（2012 - 2023年移植）与33例DBD患者（2015 - 2023年移植）进行匹配（按年龄和性别进行盲法）。评估短期结果（移植后1年，包括原发性移植物功能障碍[PGD]和重症监护病房[ICU]住院时间等结果）和中期结果（移植后5年，包括全因死亡率、排斥反应发作和移植物左心室功能等结果）。总体而言，在匹配的DCD和DBD队列之间，基线特征和结果测量（短期和中期结果）没有显着差异。与全因死亡率相关的无事件生存率在两组之间也没有显著差异(log-rank p <；0.756)。总之，我们的英国单中心数据未显示DCD和DBD OCTx患者的结局有任何差异。我们增加了越来越多的文献，支持DCD器官在心脏移植中的使用，以努力减少全球日益增长的器官需求。

期刊介绍： Clinical Transplantation: The Journal of Clinical and Translational Research aims to serve as a channel of rapid communication for all those involved in the care of patients who require, or have had, organ or tissue transplants, including: kidney, intestine, liver, pancreas, islets, heart, heart valves, lung, bone marrow, cornea, skin, bone, and cartilage, viable or stored. Published monthly, Clinical Transplantation’s scope is focused on the complete spectrum of present transplant therapies, as well as also those that are experimental or may become possible in future. Topics include: Immunology and immunosuppression; Patient preparation; Social, ethical, and psychological issues; Complications, short- and long-term results; Artificial organs; Donation and preservation of organ and tissue; Translational studies; Advances in tissue typing; Updates on transplant pathology;. Clinical and translational studies are particularly welcome, as well as focused reviews. Full-length papers and short communications are invited. Clinical reviews are encouraged, as well as seminal papers in basic science which might lead to immediate clinical application. Prominence is regularly given to the results of cooperative surveys conducted by the organ and tissue transplant registries. Clinical Transplantation: The Journal of Clinical and Translational Research is essential reading for clinicians and researchers in the diverse field of transplantation: surgeons; clinical immunologists; cryobiologists; hematologists; gastroenterologists; hepatologists; pulmonologists; nephrologists; cardiologists; and endocrinologists. It will also be of interest to sociologists, psychologists, research workers, and to all health professionals whose combined efforts will improve the prognosis of transplant recipients.
