Brief Summary:
The purpose of this study is to determine if measuring the level of a protein called Kidney Injury Molecule-1 (KIM-1) in the urine will help healthcare providers detect any problems with the transplanted kidney before the laboratory investigations that are used on a routine basis do. This approach may allow the doctor to intervene at an earlier point of a rejection episode and may thereby prolong survival of the transplant kidney.

Kidney Transplant Dysfunction

Detailed Description:


  1. To investigate the role of urinary Kim-1 excretion as a marker of delayed graft function, acute kidney allograft rejection and/or virus-induced allograft nephropathy and/or calcineurin-inhibitor nephrotoxicity.
  2. To determine the role of urinary Kim-1 excretion in predicting long term outcome after kidney transplantation compared to standard diagnostic tests.
  3. To determine the role of reduction in urinary Kim-1 excretion after a rejection episode and/or viral infection as a marker of repair of renal tubules.


Monitoring of urinary KIM-1 in kidney transplant recipients will facilitate the detection of delayed graft function, acute allograft rejection or infectious causes of proximal tubular injury, allowing earlier intervention with better long-term graft survival. Detection of urinary KIM-1 will precede increases in serum creatinine to detect acute graft injury and urinary KIM-1 will decrease faster than serum creatinine and will predict responsiveness (or lack thereof) to intervention more accurately.

Ages Eligible for Study:   3 Years to 18 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Adult and pediatric patients with chronic renal failure who are listed at Mount Sinai Hospital for a deceased donor kidney transplant and/or who are in the process of having a living donor evaluation are eligible to participate. One urine sample will be sent for KIM-1 measurement before transplantation, once the patient or the caregiver of the patient consents to participation in the study. The next specimen of urine will only be collected status post kidney transplant in the immediate post-operative phase and on routine visits thereafter. The study does not require obtaining any extra blood or urine specimens, but uses urine that would otherwise be discarded.

Inclusion Criteria:

Children and adults from the age of 3 years who are eligible transplant candidates listed for deceased donor kidney or who are scheduled for a living related or unrelated donor kidney transplant at Mount Sinai Hospital will be eligible for inclusion in this project. Patients will be recruited from the population awaiting kidney transplant treated at the Schneider Children's Hospital and Mount Sinai Hospital.
