Renal biopsies, while painful, remain the gold standard for diagnosing and classifying lupus nephritis. But what if there are less-invasive methods? In this article, I highlight key abstracts exploring innovative approaches. https://t.co/ZInKmVS2Gn @RheumNow #ACR24

Can you build systems that stop that ANA neg ENA pos anxiety? Plus $$? Lehigh Valley, Allentown, PA: lab would run ENA+dsDNA automatically, but only when ANA >1:80 (i.e. leave the ENA order to the lab) first voluntary, then compulsory it's possible! #ACR24 ABST1931 @RheumNow https://t.co/UQjWwve7DV

ANA neg, but ENA pos should we care about that result? PPV 5.5% here (similar to 6% prev @EricFMorand: https://t.co/Hyaued3rw2) and how many really needed the serology? Anxiety? Surely pos ENA w neg ANA might be more hassle than help. So what to do?⬇️ #ACR24 ABST1930 @RheumNow https://t.co/rE7RmgOGey

VERY exciting SLE update from Fava et al. Machine learning used to generate urinary protein panel predictive of intra-renal inflammation BETTER than serum biomarkers C3, C4, dsDNA Also monitoring tool for renal response. Outstanding. @RheumNow #ACRbest #ACR24 https://t.co/YXgKrSU4UQ

What a result!!! Crowed split 49% against and 51% for MCTD as a unique disease entity Given pre-debate poll of >70% for MCTD, looks like an overall win for the “NOT” group Fantastic session from all the presenters @RheumNow #ACR24 https://t.co/GgTVQ1VNWP

The anti-MCTD group strikes back Of cohort of over 1,000 RNP+ pt, only 17 clinically diagnosed with MCTD Majority of patients, despite potential overlap, treated for other primary rheum dz @RheumNow #ACR24 https://t.co/vkQ6UPs34y

Abstract 1686: Urinary proteomics reveals potential markers (MMP-13, M-CSF receptor, CD163, ALCAM, FOLR2) and pathways (neutrophil degranulation, ECM, tissue remodeling) involved in lupus nephritis Class II. @RheumNow #ACR24 https://t.co/kufd2zl9yc

Is there a less invasive approach to evaluate lupus nephritis? Abstract 1683 highlights the potential role of 68Ga-FAPI PET imaging in evaluating for lupus nephritis. FAPI uptake ↑ in pts with lupus nephritis vs HC. Correlated with IFN -α and IFN-γ pathways. @RheumNow #ACR24
