- Overview
-
Kidney transplantation is a life-saving treatment for children with end-stage kidney failure. A major threat to success is rejection, where the body’s immune system attacks and destroys the transplanted kidney. If rejection isn't treated early, it results in permanent injury that can lead to loss of the transplant and a return to dialysis. Currently, tests that monitor kidney function will miss early or mild rejection. Instead, we screen with repeated kidney biopsies, which are risky and unpleasant.
This research program will use proven techniques to identify signs of kidney injury and rejection in the urine of children who have had a kidney transplant. It will focus on the first year after transplant, since this is the highest risk for rejection. We will look for metabolites and chemokines that we have tested before to identify when injury or rejection is present. Metabolites are small molecules produced by our cells as part of their function or as waste products. Chemokines are a different type of molecule that is produced by our immune system to signal inflammation. We already know some of the changes that occur with rejection. We now plan to validate that the same changes are present in other Canadian children with kidney transplants.
We will ask children with a new kidney transplant and their families to participate in this study. They will provide a urine sample for analysis whenever they have a kidney biopsy and also at regular intervals after transplant. We will verify the metabolite and chemokine levels that are linked to rejection, and could predict rejection in other children. Once it has been refined, we will determine whether it improves outcome by using it as a test for real-time monitoring and limit our use of regular kidney biopsies. We hope to demonstrate that this will improve the accuracy to detect rejection early, reduce the number of biopsies and improve the health and long-term kidney function of children with a transplant.

The CNTRP (Canadian National Transplant Research Program)
is a CIHR co-funded large network of researchers who are collectively undertaking 6 unique research programs that are supported by 3 cores. This includes a pediatric solid organ transplant research program that will focus on age and developmental changes in the immune system, drug pharmacokinetics, viral infection susceptibility and systems-related issues affecting adherence across the spectrum of mid and late-adolescence.The PROBE Multicenter Cohort study
(Pediatric Renal transplant Optimization using BiomarkErs) is a CHIR funded program to identify urine biomarkers of kidney allograft injury such as acute rejection, in children after kidney transplantation. It follows on an initial cohort study that has identified urinary chemokines and metabolite profiles that accurately detect acute rejecton. The current study will validate these findings in a multi-center cohort, establish the time-course for appearance and disappearance of "risk" signals in the first year after transplant, and deterimine the whether these events which are not otherwise detectable are associated with worse long-term outcome as measured by histology, kidney function and development of de novo donor-specific antibodies.GrantsCanadian Institutes of Health Research (CIHR) “Applying Biomarkers to Long-term Effects in Child and Adolescent Cancer Treatment (ABLE Team).” Oct 2011-Sep 2016.

Exploring the ethics of direct contact between pediatric transplant recipients and donors
Non-anonymized direct contact between organ recipients and donor families is a topic of international interest in the adult context but there has been very little research on direct contact in the pediatric context.
