Abstract:
We studied the chronic renal allograft dysfunction in Korean renal transplants from 1 year after transplantation to 5 years. We evaluated renal function by simply using the reciprocal serum creatinine level and sought to find factors affecting the value of the reciprocal serum creatinine and graft survival, and changes of the slope of reciprocal serum creatinine. We also estimated the reciprocal serum creatinine from demographic parameters and routine laboratory results. This study included 114 patients, 87 male and 27 female who underwent renal transplantations and had functioning allografts for more than 18 month after transplantation. The results were as follows. 1) The reciprocal serum creatinine level decreased slowly and linearly. 2) There were many factors related to the reciprocal creatinine, including blood urea nitrogen, serum uric acid level, age of donors, sex of recipients, presence of acute rejecton, age of recipient, serum phosphorus, white cell count in blood, cyclosporine level in blood, hemoglobin level, posttransplantation period. We could derive the estimated reciprocal serum creatinine from data of the patients. 3) The age of the recipient and cyclosporine level at 1 year after transplantation affected the slope of the reciprocal serum creatinine during follow-up time. 4) There were 16 graft loss, including 3 functioning graft loss and 13 graft loss due to chronic allograft dysfunction. 5) Besides creatinine and BUN level at 1 year, higher blood pressure and proteinuria and lower hemoglobin levels at 1 year after transplantation were related to the graft loss from chronic allograft dysfunction. 6) There were more chronic allograft loss in patients who had lower actuarial reciprocal serum creatinine than estimated reciprocal serum creatinine. Because follow-up time was relatively short and there were only mild increases in serum creatinine level in our study, follow up of our patients for a longer-term period is required to find other factors affecting the renal allograft dysfunction.
