Death With a Functioning Graft Kidney: A Single-Center Experience of More Than 4 Decades

Objectives: Death with graft function is one of the most catastrophic events after kidney transplant. Various pre- and posttransplant risk factors have been linked to death with graft function. Characterization of this event is crucial to set successful preventive measures. Here, we reported on death with graft function among living donor kidney transplant recipients seen at the Urology and Nephrology Centre at Mansoura University (Mansoura, Egypt) throughout a period of >4 decades. Materials and Methods: This single-center study included 2953 patients who received living donor kidney transplant between March 1976 and December 2018. Patient data were retrospectively analyzed. Patients who had death with graft function were compared with other patients with regard to pre- and posttransplant data. Causes of death with graft function were also studied. Results: Among our patients (1654 male [56%] and 1299 female [44%] patients), death with graft function was reported in 9.9% of patients and responsible for 58.3% of deaths and 24.6% of graft losses. Male sex, pretransplant dialysis and blood transfusion, pre- and posttransplant diabetes and hypertension, high HLA mismatches, antithymocyte globulin induction, steroid and cyclosporine use, steroid dose, acute rejection episodes, and posttransplant infections and malignancy were significantly higher among the death with graft function group. However, multivariate analyses showed that only pretransplant diabetes, steroid dose, and posttransplant infections were risk factors for death with graft function. The most common causes of death with graft function were cardiovascular disease, infections, and malignancy. Conclusions: Death with graft function remains a significant hindrance to competent kidney transplant outcomes. We found that the most common contributors to this major event were cardiovascular disease, infections, and malignancy. More attention is needed to modify risk factors of cardiovascular disease, to update implementation policies for posttransplant vaccinations, and to conduct increased malignancy surveillance, as well to adopt less aggressive immunosuppression regimens.

Automated summary

This study examined death with graft function in kidney transplant patients over a period of more than four decades. Male sex, pretransplant diabetes, steroid dose, and posttransplant infections were identified as significant risk factors for death with graft function. The most common causes of this event were cardiovascular disease, infections, and malignancy. Attention should be given to reducing cardiovascular disease risk factors, updating posttransplant vaccination policies, and increasing surveillance for malignancy, as well as adopting less aggressive immunosuppression regimens.
