Abstract
El trasplante renal representa el mejor método para sustituir la función renal en los pacientes con enfermedad renal crónica terminal, en cualquier grupo de edad. Sin embargo, la supervivencia de los injertos renales procedentes de donantes añosos es menor que la de donantes más jóvenes. Por este motivo resulta pertinente el desarrollo y validación de modelos de riesgo predictivos que permitan optimizar el proceso de asignación de injertos de donantes añosos a los receptores más idóneos, a fin de mejorarla supervivencia del órgano y la eficiencia del procedimiento. OBJETIVOS: Los objetivos del presente estudio fueron: 1) Elaborar un modelo de riesgo(score) predictivo de supervivencia del injerto basado en variables clínicas y analíticas que permita optimizar el proceso de asignación de injertos renales procedentes de donantes añosos a receptores igualmente añosos; 2)Analizar la utilidad de dicho score en la predicción de la supervivencia global del receptor; 3) Analizar las particularidades (retraso en la función del injerto, no función primaria, tasas de rechazo, causas de pérdida del injerto, causas de muerte del receptor) del trasplante renal en pacientes añosos...
Kidney transplantation is the best method to replace renal function in patients with end-stage kidney disease, in any age group. However, the survival of renal grafts from older donors is lower than that of younger donors. Therefore, it is pertinent to develop and validate predictive risk models to optimize the process of allocating grafts from older donors to the most suitable recipients, in order to improve organ survival and theefficiency of the procedure. AIMS:The aims of the study were: 1) To elaborate a risk model (score) predictive of graft survival based on clinical and biochemical variables that allows to optimize the process of assigning renal grafts from elderly donors to equally elderly recipients; 2) To analyze the usefulness of such a score in predicting overall recipient survival; 3) To analyze the characteristics (delayed graft function, primary non-function, rejection rates, causes of graft loss, causes of recipient death) of kidney transplantation in elderly patients...
