Improved cadaveric renal transplant outcome in children

Abstract

We analyzed the results of 165 pediatric cadaver renal transplants performed at the University of California at Los Angeles to identify the factors which are linked to improved allograft survival. Both univariate life-table analysis and the Cox proportional hazard model were used. The use of a sequential immunosuppressive regimen (P<0.001) and kidneys from of more than 6 years of age (P<0.001) were found to be the factors having the most influence on primary graft survival. The sequential regimen was the only factor favorably influencing retransplants. With sequential therapy 1- and 2-year actuarial graft survival rates were 94% and 91% in primary transplants, and 82% and 70% in retransplants. Medication noncompliance exerted a large negative effect on transplant outcome. Of 70 recipients who had been on cyclosporine for at least 6 months, 50% evidenced noncompliance. Sixty-four percent of adolescents were noncompliant. Thirteen percent of the recipients lost their graft because of noncompliance. We conclude that good results can be obtained with cadaver renal transplants in children with a sequential immunosuppressive regimen and the use of kidneys from adolescent and adult donors. Noncompliance is a great barrier to long-term success in pediatric transplantation. © 1991 IPNA.
