Brief Summary

Since 1991, the Banff classification has been the gold standard for defining antibody-mediated rejection (AMR) and T-cell mediated rejection (TCMR), thereby guiding the treatment and management of transplant recipients. Starting from a pure histological approach, the classification has moved over the past three decades towards an integrated precision diagnosis system, which encompasses other expertise, such as immunology, immunogenetic, other basic sciences, biostatistics, data science, and artificial intelligence The counterpart of this constant refinement is that Banff rules are becoming complex to follow, with numerous possible scenarios leading to a high degree of inter-observer variability and misclassifications, which may lead to therapeutic consequences. The aims of this study are:

  1. 1.To integrate and decode all Banff rules and develop a computer-based application - the Banff Automation System - which provides automated and reproducible diagnoses
  2. 2.To validate the ability of the Banff Automation System to reclassify rejection diagnoses in multicenter cohort studies and clinical trials.

Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Kidney transplant recipients of all sexes recruited in observational studies performed in Europe and United States, with at least one kidney biopsy performed with all the relevant data to provide a reliable diagnosis according to the Banff classification (i.e., adequate biopsies without missing data for Banff lesion scores, donor-specific antibody status, and C4d staining).

You may qualify if:

  • Kidney transplant recipients
  • At least one kidney transplant biopsy performed, assessed with the Banff classification

You may not qualify if:

  • Inadequate biopsy according to the Banff classification (number of glomeruli inferior less than seven)
  • Missing data for Banff lesion scores
  • Missing data for donor-specific antibody status
  • Missing data for C4d (degradation product of the classic complement pathway) staining
