Optimizing HLA matching in a highly sensitized pediatric patient using ABO-incompatible and paired exchange kidney transplantation

Background Kidney transplantation is the treatment of choice for end-stage renal disease. However, since pediatric patients have long projected life-years, it is also optimal for them to get well-matched transplants to minimize long-term sensitization. In North America, pediatric kidney transplantation is largely dependent upon the use of deceased donor organs, making it challenging to identify timely, well-matched transplants. Pediatric recipients may have willing living donors who are either HLA- or ABO-incompatible (ABOi); therefore, one solution is to utilize ABOi transplants and paired exchange programs to enhance HLA matching and living donation.
