This is an extraordinary result
Teclistamab (CD3 x BCMA bispecific antibody) plus Daratumumab (CD38 antibody) vs. standard care for relapsed or refractory multiple myeloma
The future of medicine is very very bright

Seeing the light (chains): a paradigm shift in PGNMID - Kidney International kidney-international.org/art…

Dr Phil Halloran at CST on what the molecular microscope has taught us so far about kidney allograft rejection - “rejection is a chronic condition not an episode”.

We are honored to welcome 🤗 Dr Pierre Ronco as Visiting Professor at @MayoClinicNeph #MedEd
Grand Rounds tilted “New advances in immune-mediated podocytopathies: Is anti-nephrin the new anti-PLA2R?”
👩🔬 Key Conclusions
•🧪 Anti-nephrin antibodies confirmed as correlating with disease activity and likely involved in GCW alterations
•🧭 First biomarker available for diagnosis/monitoring in children + adults; may help prevent post-transplant relapses
•🧫 ELISA assays for clinical use coming soon (Euroimmun, bridge ELISA for research)
•🧩 New concept: Slit diaphragm antigens (nephrin, podocin, NEPH1, NEPH3) drive autoimmune podocytopathies
❓ Key Open Questions
•🔮 Can anti-nephrin antibodies predict steroid dependence/resistance?
•📈 Is there correlation between antibody levels and outcomes?
•🔁 Can they predict relapse?
•🧬 What are the antigenic targets in anti-nephrin negative patients (esp. primary FSGS)?
•⚠️ Are all anti-nephrin antibodies pathogenic?
•🧠 Other permeability factors yet to be found?
•⏱ Why is remission so fast after steroids?
•🧾 What is the mechanism of immunization?
•🕰 Perspective: “18 years after anti-PLA2R discovery, we still do not know everything!”

I really enjoyed this year’s ASON symposium. Learned lots, reconnected with friends and mentors, and made new friends. Grateful to @HerrmannMd, Dr Nelson Leung, and @LeticiaRolonMD for the invitation. Looking forward to next year’s symposium already! 🥂

Membranous nephropathy has undergone a paradigm shift due to the discovery of unique MN antigens.
MN has gone from idiopathic to ➡️ primary vs. secondary ➡️ where an antigen can be detected in ~80% of MN.
This is a comprehensive review of each antigen.

SPLENOMEGALY/HYPERSPLENISM
Mechanisms of splenomegaly:
• Congestive
• Work hypertrophy
• Infiltrative
What enlarges?
• Red pulp: macrophages, sinusoids, blood
• White pulp: lymphocytes, plasma cells
• Infiltrative: tumor, storage cells, granulomas, amyloid

Important new arguments for the discussion, which B cell-targeting therapy to involve in the treatment of autoimmune diseases. May be even more important in alloimmunity? ard.eular.org/article/S0003-…
Not all drug related TMA’s are made equal. But for a subset (I.e. VEGFi, Gemcitabine), terminal complement blockade allows continuation of the offending drug, with important implications for progression free survival in the long term.
Complement Inhibition Enables Anti-VEGF Receptor Therapy in Renal-Limited TMA. More options to keep patients on life-saving therapy.

Excited to share our experience using complement inhibition for re-challenging and maintaining anti-VEGF therapy in renal limited TMA. A valuable strategy to keep patients on life-saving treatment #onconephrology

Baffling: PGNMID, monoclonal no more
I got this consult case as immune complex-MPGN
LM- MPGN pattern
IF- IgG, C3, C1q, kappa & lambda 3+
Did IgG subtypes-IgG3 3+, all others negative
EM- mottled deposits
Dx- Proliferative GN, IgG3, but ? with monoclonal IgG deposits (PGNMID)
