Renal Forum.

The aim of the present study was to define the most important risk factors for mortality after renal transplantation in a population representing the real medicine in the modern immunosuppressive era.

In a  multicentric study we included 2592 patients (from 14 hospitals)  (Renal Forum Group) who received a renal transplant from deceased donors between 2000-2002  and prospectively followed for 10 years always for the same team. According recipient age, 672 were under forty, 1320 among 40-60 yr and 600 were older than 60 yr. They received steroids, TAC preferently than CyA, and MMF with or without induction (KI 2008). Induction therapy Tymo with steroids, TAC/CyA) and MMF was used in hyperimmunized patients (12.5%).

Patient survival at 10 years was 80.5%, statistical significant different depending recipient age: 95% youngs, 84% middle age and 55% older people.  At ten years 80% of patients were maintained with TAC/CyA and 30% were steroids free. 

The most frequent causes of mortality were cardiovascular (CDV) , infection and cancer in  the three categories. Notably in the group under forty, 30% of deaths were of CDV origin, 19% due to infection and 15%  due to cancer.

Risk factors for mortality in the total group were: recipient and donor age, reciepint hepatitis C positive, pretransplant CDV, pretransplant diabetes and delayed graft function. In the multivariate analysis, recipient age is a strong risk factor in all groups, however in young patients pretransplant diabetes, in the middle age pretransplant CDV and in older people serum creatinine at 6mo were the most significant risk factors for mortality.

Censored death graft  survival was 72.6% globally, 76%, 71% and 65% in the three categories according recipient age, respectively.

In conclusion, In our current clinical practice 20% of patients died at 10 years posttransplant. Recipient age is a dominant risk factor and notably pretransplant diabetes in young people, pretransplant CDV in middle age and renal function in older people are the most significant factors for mortality.
