Validating Injury to the Renal Transplant Using Urinary Signatures in Children (VIRTUUS)

Project Summary

Transplant rejection contributes to irreversible damage to the transplanted organ. Sub-clinical detection of transplant rejection (when no definite or readily observable clinical symptoms are present) and detection of other post-transplantation complications using non-invasive means, such as urinary biomarkers, will allow earlier diagnosis of rejection. This approach will ultimately allow less aggressive and earlier intervention, and thus preserve transplant function. The purpose of the study is to investigate whether the existing urinary mRNA and metabolite profiles used for detection of early kidney transplant injury in adults can also predict rejection and other complications of kidney transplantation in children. 

This is a prospective, observational, multicenter, cohort study coordinated at the Children's Hospital of Philadelphia. BC Children's Hospital is one of the participating research sites, led by Dr. Tom Blydt-Hansen (site investigator).
