ABSTRACT
Different donor parameters and baseline biopsy have been used to assess the quality of donor organs. There is, however, no consensus which risk factors and chronic changes in the donor kidney can be accepted for transplantation. The study included 481 deceased organ donors and their 829 kidney recipients transplanted during 1995-2005. The biopsies were re-evaluated according to the Banff 97 classification. The prognostic significance of donor risk factors and Chronic Allograft Damage Index (CADI) was analyzed. We propose a new donor risk score, calculated as the count of positive risk factors from a defined set of factors in the medical history of the donor. This donor risk score predicts histological quality of the kidney, graft function, and survival. Transplantations from donors with donor risk score >4 had significantly decreased graft survival compared to those with donor risk scores 0-4; the five-yr death-censored graft survivals were 83% vs. 93%, respectively. High donor CADI score (>3) was associated with worse graft function and survival. Three-yr glomerular filtration rate declined from 82 to 49 mL/min with donor CADI increase from 0 to ≥4. Our results show that high donor risk score and CADI value reflect low functional reserve and risk for poor graft outcome.
