How many gene transcripts do you actually need to diagnose rejection phenotypes after kidney transplantation? In our latest study in @KIReports, we found that the answer is surprisingly low! kireports.org/article/S2468-… 1/6

🧬Excited to share our new paper in @amjtransplant “Molecular diagnosis of kidney allograft rejection using the B-HOT gene panel” amjtransplant.org/article/S1600-… #MolecularDiagnostics #Transplantation

Evolving the Banff Classification for Kidney Allograft Rejection. This review paper by @_B_Chauveau et al. reports that innovations are reshaping rejection diagnostics! #Transplantation #KidneyTransplant #Transplantation #TXPforAll tinyurl.com/zh6m6wh6

We now have a mass spectrometry test available for membranous nephropathy (MN) antigens. Started in 2017 with no lab/funding (& still no lab/major funding)-one at a time-we were able to discover majority of MN antigens. It was an idea that worked out. news.mayocliniclabs.com/2025/01/21/ass…

Kidney-transplant microvascular inflammation has a varied clinical presentation. This study of more than 16,000 biopsy specimens supports the recognition of additional rejection phenotypes to standardize diagnostics. nej.md/4hiFoyJ #KidneyWk

Dive into the #HORUS_CMV project with @hKminski, sharing insights on the team's efforts to understand #CMV's impact on transplant patients. Learn how they’re identifying signatures for personalised care to improve patient outcomes. Watch the full video: horus-project.eu

Glad to share our @EUTRAIN_project paper published in @Kidney_Int! 🙌   🙏 to the amazing #consortium behind this #biomarker validation study funded by @EU_Commission @HorizonEU 🇪🇺   @AlexandreLoupy C. Lefaucheur @ParisTxGroup @ESOTtransplant @ttsorg   kidney-international.org/article/S0085-…

⚠️Happy to share our preliminary results on Imlifidase together with the French transplant community. 🙏🏻 @KamarNassim @dommibertrand @CaillardSophie @SFTfrancophone @SFTJuniors More to come in 2025 🚨 kireports.org/article/S2468-…

Abstract time for the #Banff2024 allograft pathology meeting 👇🏻👇🏻

@ChangUCanSpare @JZRenalPath @AskRenalPath Thank you for your advice! I will do it.

@JZRenalPath @_B_Chauveau @AskRenalPath I would favor nonspecific entrapment. I also would emphasize the extent of irreversible scarring. If they plan to treat this patient, they should not expect the creatinine to improve very much, if at all

Male in his 80’s. Waldenström (no TTT). IgM kappa 10g/L CKD with SCr 1.86 mg/dl. Prot 0.19 g/g FFPE: ischemic glomeruli, stripped fibrosis 65% & >=cv2 Frozen: granular IgM kappa deposits in intimal fibrosis of an arcuate artery. No other deposits 1/2 #AskRenalPath @AskRenalPath

@JZRenalPath @AskRenalPath Thank you for your insightful suggestions. I will at least ensure that the nephrologist carefully checks for a cryo and biological TMA features.

@_B_Chauveau @AskRenalPath Alternatively. Organizing mucoid intimal edema due to microangiopathy with some non-specific trapping of circulating paraprotein?

Congo red -. EM: not available What should I call this? Any advices? 🙏 2/2 #AskRenalPath @AskRenalPath @Tiff_Caza @JZRenalPath @MRabant @CandiceRoufosse @Ijeb @ChangUCanSpare

More on “atypical anti-GBM disease”! Worldwide collaborative by B Chauveau et al published in @AJKDonline doi.org/10.1053/j.ajkd… also see my commentary “Anti–GBM Disease: Broadening the Spectrum” doi.org/10.1053/j.ajkd… #renalpath @Renalpathsoc @MayoClinicNeph @MayoClinicPath

Our study on post-transplant TMA is out! TMA is mostly driven by AMR and CNI toxicity but often due to multiple factors, with higher rates of complement pathogenic variants, and associated with a poor prognosis.

A nice collaborative work from the French Nephropathology Group!

@ClahsenMarian Very nice data, congrats! Of note, reference 41 is worth checking: it seems to be either an abstract in NDT in 2020 or an original article in Am J Transplant in 2023, but not Am J Transplant 2020.
