Description of intervention(s) / exposure
Other interventions - Non interventional

No rejection, normal biopsy (controls) - Normal biopsy - no acute tubular injury (ATI), rejection or any other pathology

Acute kidney injury without evidence of rejection - Biopsy features of acute tubular injury but no evidence of rejection

Subclinical Rejection - Biopsy features of injury and inflammation but not meeting current diagnostic criteria for acute or chronic rejection

Acute rejection - Biopsy features of T-cell mediated, antibody-mediated, or mixed rejection

Isolated vascular rejection - Biopsy features of inflammation in the blood vessels only

Isolated glomerulitis - Biopsy features of inflammation in the glomeruli only

Chronic (active) rejection - Biopsy features of chronic rejection - T-cell, antibody or mixed types

BK virus associated nephropathy (BKVAN) - Biopsy features of SV40 positive staining in tubules to diagnose BKVAN

Summary
Brief summary
The study is an investigator-led, prospective, longitudinal, observational cohort study.

The central hypothesis for this study is that spatial data will reveal new insights to immune
cell function and local interactions within the kidney tissue to better predict important
clinical outcomes. Investigators aspire to establish a prospective, longitudinal cohort to
improve the diagnosis and management of kidney transplant rejection using precision
pathology.

By utilising new spatial technologies, the investigators aim to:

- Derive a spatially resolved transcriptomic signature of kidney transplant rejection
subtypes

- Derive accurate transcriptomic signatures aligned with key cell types within the
transplant kidney

- Develop refinements to histological kidney rejection diagnostic and scoring
classification

- Correlate of spatial and refined biopsy scoring features to clinically important
outcomes
