Abstract
El Kidney Donor Profile Index (KDPI), junto a otras variables del donante y receptor, puede optimizar el proceso de asignación de órganos. Este estudio tiene como objetivo comprobar la aplicabilidad del KDPI en una población española, así como su capacidad de predicción de la supervivencia del injerto y del paciente. Se estudiaron 2.734 trasplantes renales realizados en Andalucía entre enero de 2006 y diciembre de 2015. Los casos se agruparon por edad del receptor y cuartil del KDPI, y se compararon entre grupos tanto la supervivencia del injerto como la del paciente. El KDPI discriminó con precisión los órganos óptimos de los subóptimos o marginales. Para receptores entre 18 y 59 años, el hazard ratio es de 1,013 (p<0,001) para supervivencia del injerto censurada para muerte y de 1,013 (p=0,007) para supervivencia del paciente. Para receptores mayores de 60 años, el hazard ratio es de 1,016 (p=0,001) para supervivencia del injerto censurada para muerte y de 1,011 (p=0,007) para supervivencia del paciente. Un análisis multivariante identificó como factores predictivos de la supervivencia del injerto el KDPI, la edad del donante, la donación tras muerte circulatoria, la edad y el sexo del receptor. El KDPI permite relacionar, a grandes rasgos, las características del donante con la mayor o menor supervivencia del injerto y del paciente en la población española. No obstante, debido a ciertas limitaciones, convendría elaborar un índice propio a partir de los datos españoles o europeos. En este trabajo se identifican algunos factores predictivos de la supervivencia del injerto que pueden servir como primer paso en esa línea.
The Kidney Donor Profile Index (KDPI), together with other donor and recipient variables, can optimise the organ allocation process. This study aims to check the feasibility of the KDPI for a Spanish population and its predictive ability of graft and patient survival. Data from 2,734 kidney transplants carried out in Andalusia between January 2006 and December 2015 were studied. Cases were grouped by recipient age, categorised by KDPI quartile and both graft and patient survival were compared among groups. The KDPI accurately discriminated optimal organs from suboptimal or marginal ones. For adult recipients (aged: 18-59years) it presents a hazard ratio of 1.013 (P The results obtained show that the KDPI makes it possible to relate the donor's characteristics with the greater or lesser survival of the graft and the patient in the Spanish population. However, due to certain limitations, a new index for Spain based on Spanish or European data should be created. In this study, some predictive factors of graft survival are identified that may serve as a first step in this path.
