Abstract

Evidence on the evolution of graft function in kidney transplant recipients recovering from coronavirus disease-2019 (COVID-19) is lacking. This multicenter observational study evaluated the short-term clinical outcomes in recipients with acute kidney injury (AKI) secondary to COVID-19. Out of 452 recipients following up at five centers, 50 had AKI secondary to COVID-19. 42 recipients with at least 3-month follow-up were included. Median follow-up was 5.23 months [IQR 4.09-6.99]. Severe COVID-19 was seen in 21 (50%), and 12 (28.6%) had KDIGO stage 3 AKI. Complete recovery of graft function at 3 months was seen in 17 (40.5%) patients. Worsening of proteinuria was seen in 15 (37.5%) patients, and 4 (9.5%) patients had new onset proteinuria. Graft failure was seen in 6 (14.3%) patients. Kidney biopsy revealed acute tubular injury (9/11 patients), thrombotic microangiopathy (2/11), acute cellular rejection (2/11), and chronic active antibody-mediated rejection (3/11). Patients with incomplete recovery were likely to have lower eGFR and proteinuria at baseline, historical allograft rejection, higher admission SOFA score, orthostatic hypotension, and KDIGO stage 3 AKI. Baseline proteinuria and the presence of orthostatic hypotension independently predicted incomplete graft recovery. This shows that graft recovery may remain incomplete after AKI secondary to COVID-19.

摘要

关于2019冠状病毒病(COVID-19)康复期肾移植受者移植肾功能演变的证据尚缺。这项多中心观察性研究评估了继发于COVID-19的急性肾损伤(AKI)受者的短期临床结局。在五个中心随访的452名受者中,50名继发于COVID-19的AKI。纳入了42名至少随访3个月的受者。中位随访时间为5.23个月[四分位间距4.09 - 6.99]。21名(50%)出现重症COVID-19,12名(28.6%)有KDIGO 3期AKI。17名(40.5%)患者在3个月时移植肾功能完全恢复。15名(37.5%)患者蛋白尿加重,4名(9.5%)患者出现新发蛋白尿。6名(14.3%)患者移植失败。肾活检显示急性肾小管损伤(9/11例患者)、血栓性微血管病(2/11)、急性细胞性排斥反应(2/11)和慢性活动性抗体介导的排斥反应(3/11)。恢复不完全的患者在基线时可能有较低的估算肾小球滤过率(eGFR)和蛋白尿、既往移植排斥反应、较高的入院序贯器官衰竭评估(SOFA)评分、体位性低血压和KDIGO 3期AKI。基线蛋白尿和体位性低血压的存在独立预测移植恢复不完全。这表明继发于COVID-19的AKI后移植恢复可能仍不完全。
