Brief Summary

Banff classification stands as gold standard and international consensus for the identification, diagnosis and categorization of renal allograft pathology. In addition to multiple revision dedicated to the clarification and refinement of these diagnostic categories, a special attention is now dedicated to the development of automated protocols serving the use of artificial intelligence in digital pathology. To be integrated in the actual early post-transplant monitoring procedure, such original approach is considered to match various growing expectations of clinicians and pathologists regarding the future of transplant nephropathology : decrease inter-observer variability, reduce human errors and limit time-consuming analysis of kidney biopsy. Among these, an accelerated reading and access to Banff diagnostic criteria could help initiating both appropriate and immediate treatment to improve graft survival in kidney transplant recipients. Yet conventional histopathology still requires the preparation of a paraffin block, sections as well as subsequent colorations that altogether delay the final pathological diagnosis and urge the need for additional diagnostic modalities. Designed to overcome this critical limitation, the HARBOR study intends to test the performance of direct histopathological examination of fresh kidney biopsy with full-field optical coherence tomography for the identification of Banff elemental lesions and diagnostic categories.

Conditions

Tomography, Optical Coherence; Kidney Transplantation

Keywords

Kidney Transplantation; Kidney Biopsy; Full-field Optical Coherence Tomography

Outcome Measures

Primary Outcomes (1)

• Banff lesion scores based on dynamic full-field optical coherence tomography measurement

  Provide a better understanding of the ability of dynamic full-field optical coherence tomography to identify and score the usual Banff lesions comprising interstitial inflammation, tubulitis, intimal arteritis, glomerulitis, peritubular capillaritis, interstitial fibrosis, tubular atrophy, vascular fibrous intimal thickening, glomerular basement membrane double contours, mesangial matrix expansion, arteriolar hyalinosis, hyaline arteriolar thickening, total inflammation and inflammation in the area of both interstitial fibrosis and tubular atrophy. Note that the the Banff scoring system has three grades for each lesion : from mild (1) to moderate (2) and severe (3). In each case, the higher the score the worse the outcome, according to the 2018 Reference Guide to the Banff Classification of Renal Allograft Pathology

  Outcome measure is assessed 15 days following kidney transplant biopsy

Secondary Outcomes (1)

• Banff diagnostic categories based on dynamic full-field optical coherence tomography measurement

  Outcome measure is assessed 15 days following kidney transplant biopsy

Study Arms (1)

The DIVAT cohort

patient \> 18 years of age who received renal transplant are registered in the DIVAT cohort (standing for computerized and validated data in transplantation, "Données Informatisées VAlidées Transplantation"). It comprises more than 300 clinical and biological parameters collected at the time of transplant, at 3 months, 6 months and at each anniversary of the transplant. The DIVAT cohort and network is accredited by the CNIL (standing for "Commission Nationale de l'Informatique et des Libertés")

Other: Dynamic full-field optical coherence tomography analysis of kidney transplant biopsy
