ABSTRACT
PURPOSE: To evaluate whether control of risk factors associated with worse results has improved graft survival, with respect of renal function quality and other factors influencing graft survival: recipient age, immunosuppressive therapy, cold ischemia time, acute tubular necrosis (ATN), acute rejection episodes (ARE) and 1-month creatinine levels. MATERIALS AND METHODS: Retrospective review of 147 patients who underwent kidney transplant between 1995 and 2001. Inclusion criteria were donor and recipient age older than 60 years, first renal transplant, follow-up period longer than 12 months, donor creatinine clearance higher than 75 mL/min, and less than 20% glomerulosclerosis observed in donor renal biopsy. RESULTS: Graft survivals were 87%, 83%, 78%, and 70% at first, second, third, and fifth year after transplantation, respectively. Mean serum creatinine levels were 2.3 mg/dL and mean follow-up time, 46 months. Multivariate analysis using a Cox regression model identified donor age, ARE, and serum creatinine levels 1 month after surgery as independent variables affecting graft survival. Recipient age, immunosuppressive therapy, and serum creatinine levels at 1 month after surgery were predictive variables of recipient survival. DISCUSSION: Renal transplantation is an accepted therapeutic option in elderly patients with chronic renal insufficiency, if both donor and recipient are carefully selected.
