ACR25 - Day 1 Report
ACR 2025 began today in Chicago with throngs of rheumatologists, fellows, ARP members, APPs and pharma folk taking to the meeting halls and rooms for tons of novel content.

Abstrat 1414 Compared to #PsO, early #PsA showed:
🔹 ↑ Dactylitis (66%), Enthesitis (78%), CRP/ESR
🔹 Longer morning stiffness & ↑TJC/SJC
🔹 MRI/US: frequent tenosynovitis & bone changes
🔹 Predictive model combining these features showed Sens 89%, Spec 84%

Analysis from FVSG identified 36pts with anti-rituximab antibodies
In AAV, lookout for this in pts who are MPO+ & w/higher CD19 at 6 mos. Worse relapse free survival in both AAV & CRYO!
@TerrierBen can you share the prevalence of these abs?

Avouac et al. Lipid changes after JAKi initiation. 85 patients. Increases at 6 months. Largely appeared driven by HDL increase, and correlated CRP decrease. Appeared transient with return to baseline with time. @RheumNow #ACR25 Abstr#1333 https://t.co/CQ6u3ck1Ch

In pooled PsA trials (n=1222), deucravacitinib reduced disease activity–linked proteomic scores in both sexes by Week 16. Proteomic profiling identified 133 unique proteins in males and 177 in females vs sex-matched healthy controls. Females showed greater enrichment in https://t.co/TTAWUtOLP0

Sex based differences in PsA proteomics
Analyse from POETYK PSA 1 & 2 deucravacitinib RCT
Large overlap but female pts specificities, Upregulation of:
-JAK STAT pathway
-Cytokine interaction
Linked with higher disease activity in female groups
Yes Correlation, but not https://t.co/VwiVOkxpoB

#0850 Single-cell RNA-seq of RA synovium uncovers a new biomarker & therapeutic target: PHIF
Made by Tph cells, drives macrophage activation and mirrors disease severity.
Big step forward in understanding RA immunopathogenesis. @RheumNow #ACR25 https://t.co/KtyxU0Lqly

Urinary Tenascin C predicts kidney function loss in lupus nephritis
170 AMP-LN patients: Tenascin C (from renal myofibroblasts) was the top predictor of eGFR decline (HR 4.6)
Proteomic 11-marker risk score (AUC 0.91) outperformed proteinuria for prognosis #ACR25 @RheumNow

The CLASSIC study (n=1015, 27 countries) validated revised ASAS-SPARTAN axSpA criteria. Final model achieved 79.5% sensitivity & 90.4% specificity vs global diagnosis. MRI SIJ (active + structural) was strongest predictor. HLA-B27, CRP, IBD, uveitis also included. Abstract#0854 https://t.co/GjSHE2ihVI

#0853 Olink proteomics in anti-Ro+ pregnancies identifies macrophage-derived IL-6 & CCL3 as serum predictors of foetal AV block
These pro-inflammatory proteins predicted fAVB independent of maternal diagnosis or Ab titres, pointing to new pathogenic pathways. @RheumNow #ACR25

What is the #frequency of #CTD #ILD in #USA?
Data from #Marketscan >9K & #Optum ~20k CTD-ILD Pts
56-65 yrs, 3/4 F
?under ascertained #RA-ILD - low % but #SSc-ILD approx 16% clinically relevant
Same as Ont, Canada #SSc-ILD %
Not rare

We need more biomarkers in GCA - what about fibrinogen?
Miller et al retrospectively compared CRP, ESR, and fibrinogen at different points in GCA dx
Fibrinogen (and ESR/CRP) only helpful prior to initiation GC with comparable performance

Abstract 0842
💡 Urinary biomarkers as the next frontier for monitoring lupus nephritis activity
🔹 Proteinuria didn’t track w/ histologic activity
🔹 IL-16 & sCD163 correlated at baseline only
🔹 Urinary Tenascin C & BAFF correlated w/ activity at 1 yr

Could a sputum test predict risk for RA conversion in at-risk patients?
98 at risk pts, Converters had higher
-BL sputum CCP levels
-BL Sputum nucleosome and cit-nucleosome levels !although not asso after adjusting for sputum anti-CCP-IgA level
In converters, correlation of https://t.co/bqmQqS1Jz5

More biomarkers predictive of conversion to clinical RA in at-risk pts
Serum PAD4 & PAD 4 levels measured in CCP+ at-risk individuals
-PAD4 (not PAD2) increased in RA Converters vs. non converters and HC
-PAD4 levels Pre-RA = RA
Within high CCP+ at risk individuals, higher https://t.co/LU5zUzui1G

A simple flow cytometry analysis of peripheral blood monocytes to predicts progression to clinical RA or PsA in at-risk patients?
Too good to be true!
284 RA 56 PsA 57 HC
-HLA-DR higher in PsA
-CD11c lower in RA
But no clear difference between Converters and non Converters https://t.co/f3Sett4eXd

Urinary proteomics reveals promising biomarkers for ankylosing spondylitis. PIK3IP1 & SDC1 levels were significantly elevated in AS patients, showing strong diagnostic performance (AUCs: 0.852 & 0.875). Combined with AMY1A, the multiplex panel reached an AUC of 0.973.

New biomarkers 14-3-3η multiplex autoantibody assay improves axSpA diagnosis, especially in HLA-B27– patients. Combined with CRP & HLA-B27, detection rose to 99% (training) & 91.4% (evaluation). In HLA-B27– cases, 14-3-3η lifted detection to 70.6% & 55%. Abstract 0531 @RheumNow
