Kidney Transplant Biopsies for Cause
The study population includes patients with a functioning kidney transplant undergoing a biopsy for clinical indications as standard of care to determine the cause of their graft dysfunction (deterioration in graft function, delayed graft function, proteinuria).
- Validate the Integrated Diagnostic System in the International Collaborative Microarray (INTERCOM) Study [ Time Frame: 2013-2016 ]
- The rejection classifier predicts Banff diagnosis of any rejection: ABMR, TCMR, or mixed ABMR and TCMR;
- The TCMR classifier predicts the presence of Banff TCMR lesions/diagnoses;
- The ABMR classifier predicts the presence of ABMR lesions;
- In late (>1yr) biopsies for clinical indications, the failure classifier predicts failure within three years.
- Demonstrate the feasibility of molecular phenotyping of 300 + 500 kidney transplant biopsies for clinical indications. [ Time Frame: 2014-2016 ]To test the hypothesis that the molecular phenotype of a newly acquired sample predicts the histologic and clinical features of this sample.
- Demonstrate the feasibility of molecular phenotyping of 500 biopsies in real time i.e. returning the molecular phenotyping report in two working days upon sample arrival. [ Time Frame: 2015-2016 ]Refine the reports based on feedback from the participants.
