title: Renal graft outcome after combined liver and kidney transplantation in children: UCLA and UNOS experience.
abstract: Although it has been described in adults that renal grafts in the context of CLKT have a lower number of AR episodes and improved renal allograft survival, this has never been examined in pediatrics. We performed a single center retrospective case-control study examining 10 patients aged 10+/-6 yr with a CLKT that survived the post-surgery period of six months, and compared outcomes to a group of 20 KO transplants matched for age, era, and immunosuppression. We observed a significant reduction in the incidence of AR episodes in the CLKT group. To evaluate whether or not this experience was reproducible nationally, we performed an analysis of the 1995-2005 UNOS database. As of March 2007, 111 CLKT and 3798 KO transplants were identified from the OPTN/UNOS data. There was a significant improvement in the late kidney graft survival at five yr post-transplant in the CLKT group. These findings support the concept that liver transplantation is immunologically protective of the kidney allograft in CLKT.
