Outcomes and factors leading to graft failure in kidney transplants from deceased donors with acute kidney injury-A retrospective cohort study. PLoS One 2021; 16:e0254115.

Abstract
Due to shortage of donor, kidney transplants (KTs) from donors with acute kidney injury (AKI) are expanding. Although previous studies comparing clinical outcomes between AKI and non-AKI donors in KTs have shown comparable results, data on high-volume analysis of KTs outcomes with AKI donors are limited. This study aimed to analyze the selection trends of AKI donors and investigate the impact of AKI on graft failure using the United states cohort data. We analyzed a total 52,757 KTs collected in the Scientific Registry of Transplant Recipient (SRTR) from 2010 to 2015. The sample included 4,962 (9.4%) cases of KTs with AKI donors (creatinine ≥ 2 mg/dL). Clinical characteristics of AKI and non-AKI donors were analyzed and outcomes of both groups were compared. We also analyzed risk factors for graft failure in AKI donor KTs. Although the incidence of delayed graft function was higher in recipients of AKI donors compared to non-AKI donors, graft and patient survival were not significantly different between the two groups. We found donor hypertension, cold ischemic time, the proportion of African American donors, and high KDPI were risk factors for graft failure in AKI donor KTs. KTs from deceased donor with AKI showed comparable outcomes. Thus, donors with AKI need to be considered more actively to expand donor pool. Caution is still needed when donors have additional risk factors of graft failure.

Donor Ethnicity and Kidney Transplant Outcomes in African Americans. Transplant Proc 2020; 53:885-888. [PMID: 32980134 DOI: 10.1016/j.transproceed.2020.06.042] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Accepted: 06/04/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Transplantation of African American (AA) compared to non-AA donor kidneys is generally associated with inferior outcomes. It is unclear whether enhanced genetic risk associated with AA donor kidneys would be counterbalanced by favorable immunologic matching when AA donor kidneys are transplanted into AA recipients. We aimed to compare the outcomes of AA vs non-AA deceased-donor kidneys (DDKs) stratified by kidney donor profile index (KDPI) that were transplanted into AA recipients. METHODS Using the Organ Procurement and Transplant Network/United Network for Organ Sharing database, we identified AA DDK recipients from 2000 to 2015 who received peri-operative induction followed by calcineurin inhibitor/mycophenolate mofetil maintenance. These patients were divided into 4 KDPI groups (0%-20%, 21%-50%, 51%-85%, and 86%-100%). Adjusted long-term graft and patient outcomes were compared between AA recipients of kidneys from AA vs non-AA donors in each KDPI category using a multivariable Cox model. RESULTS Among a total of 17,516 AA DDK transplant recipients, 3303 were in KDPI 0%-20% (AA donor = 239; non-AA donor = 3064), 5821 in KDPI 21%-50% (AA donor = 1414; non-AA donor = 4407), 6364 in KDPI 51%-85% (AA donor = 1619; non-AA donor = 4745), and 2028 in KDPI 86%-100% (AA donor = 932; non-AA donor = 1096) groups. Adjusted overall graft, death-censored graft, and patient survival were similar between AA recipients of AA vs non-AA donor kidneys across all KDPI groups. DISCUSSION Our study showed similar outcomes for transplanting AA vs non-AA deceased-donor kidneys into AA recipients despite the generally observed inferior outcomes associated with AA donor kidney transplantation.
