Abstract:
Objective:Remuzzi scoring system is utilized for assessing the degree of renal tissue damage in donors with hypertensive cerebral hemorrhage and donors with brain trauma after cardiac death. To explore the prognosis of hypertensive cerebral hemorrhage donor kidney in renal transplant recipients.
Methods:The kidney donated by DCD between January 1, 2016 to June 1, 2018 were retrospectively reviewed. Pathological biopsy was performed before transplantation and hematoxylin-eosin (HE) staining after sectioning. The degree of renal tissue lesions was evaluated by Remuzzi scoring system. According to the source of donor kidney, they were divided into two groups of donors with heart failure due to hypertensive cerebral hemorrhage (HCH) and those with brain trauma (BT). Both groups of donor kidneys were preserved by low-temperature machine perfusion. The immunosuppressive regimen was identical in both groups. The prognosis of two groups was compared by serum creatinine (Scr) at Month 1/6/12 post-operation and cumulative graft survival rate over a follow-up period of 12-36 months.
Results:The renal Remuzzi score of HCH donors was significantly higher than that of BT donors. The maximal creatinine clearance rate was significantly lower than that of BT donors [(86.8±27.8) vs (115.4±23.2) ml/min, P<0.05]. At 1/6/12 months post-transplantation, serum creatinine levels were (76.1±18.5), (72.4±16.2) and (71.4±16.8) μmol/L in BT group and (160.3±33.4), (154.3±32.6) and (146.4±29.1) μmol/L in HCH group. The SCr in BT group at 1/6/12 months was lower than that in HCH group (P<0.05). Kaplan-meier analysis showed no significant inter-group difference in graft survival between two groups over a follow-up period of 12 to 36 months (Log-Rank test, P=0.485).
Conclusions:No significant difference exists in short-term survival rate of kidneys from HCH and BT donors. The recipients of HCH donor's kidney have higher serum creatinine levels than those of BT donors. Selective use of kidney transplants in patients with cardiac death caused by HCH may greatly reduce the waste of donor kidney and improve the quality-of-life of patients with end-stage renal disease.
