#1726 IA from immune checkpoint inhibitors (ICI) is a distinct autoimmune entity: T cell-driven but not antibody-mediated
irAE arthritis shows hyperactive, cytotoxic CD8+ T cells & metabolic reprogramming, unlike RA. IL-6, IL-12 & IFNα fuel this process. @RheumNow #ACR25

Overview of the use of SARD-ILD by @drdavidliew covering the challenges, professionalism, explainability and interpretability. Think of using and validating AI in the same way we train our residents. The human interface still needed @RheumNow #ACR25 https://t.co/TYKud057ag

#1725 Functional NOTCH4 variants contribute to vasculopathy & fibrosis in SSc, particularly in African-American patients
NOTCH4 hyperactivation disrupts angiogenesis & drives EndoMT; inhibition (including with FDA-approved Nirogacestat) restores vascular repair @RheumNow #ACR25

#1724 MAIT cells central in RA pathogenesis. These innate-like T cells accumulate in synovial fluid, driving fibroblast activation, cytokine release & joint damage. Blocking MAIT activation or deleting MR1 reduces arthritis in mice- a potential new target in RA. @RheumNow #ACR25

The Power of Gamma Delta T Cell for Autoimmunity https://t.co/wIMu5r7b3D
More on T Cell engagers , this time with gama delta T cell ( tiny but mighty ). Kate Roslin talks about advantages of this protocol. (No cytokines thus less toxicity).

Pooled data fr diff SLE cohorts by Dr SGarg et al were evaluated to determine an upper threshold tx range of HCQ
750-1150 ng/mL: safe & effective HCQ levels
>1150ng/mL-supratx, no added tx benefit
CKD st >/=3: 2x ⬆️odds of toxic hcq levels

#1723 Why is systemic autoimmunity more common in females?
Loss of X-chromosome inactivation maintenance in B cells (not T cells) amplifies interferon-driven disease, with increased autoantibodies, inflammation and renal injury. Key mechanistic advance. @RheumNow #ACR25

3rd plenary session!
#1722 Defining safe HCQ levels in SLE: whole-blood 750-1150ng/mL= therapeutic range; >1150ng/mL ➡️ ~2× toxicity risk; <750ng/mL ➡️ higher flare risk
CKD ≥3 increases odds of supratherapeutic levels
New era of precision monitoring in SLE?

Plenary 3, HCQ blood levels in SLE
HCQ level > 1150: 1.9x risk of HCQ toxicity
HCQ level < 750: 1.4x risk of active SLE
HCQ dose < 5mg/kg: 1.9x risk active SLE
My take home? Blindly reducing dose to <5mg/kg is BAD; use levels instead!

Late-Breaking Trials in axSpA and PsA https://t.co/Fw8wiAPLoN
The amazing @Janetbirdope discussing head to head trials in Axial SpA and PsA with primary failure to TNF.
To switch to another TNF or IL17?
IL17 for my PsA patient for sure.
