Abstract

Introduction Many factors determine the outcomes of renal transplant, including characteristics of both donors and recipients. Antihuman leukocyte antigen donor-specific antibodies are strongly linked to antibody-mediated rejection and late allograft loss. Aim The aim was to determine the effect of recipient and donor characteristics on kidney transplant graft survival, with special stress on panel-reactive antibodies. Participants and methods This study included 168 adult recipient and donor couples. The authors analyzed data of kidney transplants performed between the years of 2008 and 2018 at National Institute of Urology and Nephrology. Results The authors found a significant increase in renal failure in recipients transplanted with unrelated donor kidney and in positive hepatitis C virus antibodies (HCV Abs) recipients (P = 0.002 and 0.001, respectively) and renal complications (P ≤ 0.001). There was also a significant increase in panel-reactive antibody-positive recipients to get renal complications (P = 0.03). There was a significant increase in renal failure with old-aged recipients (P = 0.008) and with increased duration of transplant (P = 0.003). By multivariate regression, the authors deduced that young age decreases graft loss risk (hazard ratio (HR): 0.88; 95% confidence interval (95% CI): 0.79–0.97; P = 0.017). Recipients of unrelated donor graft and HCV infection were associated with higher hazard ratio graft loss (HR: 13.56; 95% CI: 2.58–71.22; P = 0.002, and HR: 7.96; 95% CI: 1.04–60.44; P = 0.45). Unrelated donors graft were associated with 4 times higher hazard ratio renal complication (HR: 4.18; 95% CI: 2.01–8.72; P = 0.003). HCV infection increases risk three times (HR: 3.24; 95% CI: 1.31–7.99; P = 0.010). Unrelated donor was a significant independent predictor for recipient graft loss risk in a period of more than 5 years after transplantation. Conclusion The authors concluded that recipient and donor characteristics have important roles on kidney transplant graft survival and also on renal complications.
