Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

SPECIFIC AIMS:

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.

HYPOTHESIS:

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.
