EULAR 2025 - Day 1 Report
Wednesday was Day One at EULAR 2025 in Barcelona. Thousands from around the world gathered, eager to reunite at this international educational forum. Below are a few of my favorites from Day 1.

Yes, it is relevant to ask patients about physical joint strain in RA and propose strain specific interventions
In ACPA+ RA pts for each 10% increase in strain, 7% increase in SJC44 and 5% MRI inflammation

We should address patients anxiety at RA diagnosis:
cohort 250+ newly diagnosed RA pts
-49% reported anxiety
-41% by 3 months
Anxiety asso w/ CDAI, PROs and 3-5 fold increase in prescription of bio/tsDMARDs
Analysis reasonably adjusted

BioDMARDs reduce polyimmunity in RA
Danish Registry based cohort study 5 yrs follow up
25000+ pts
Polyimmunity in csDMARDs treated group 2.2% vs. 1.7% in bioDMARDs group
HR 0.74
Most frequent autoimmune thyroid disease

Leeds study of 223 ACPA+ Arthralgia pts w quant. MRI of hand showing tenosynovitis (34% at baseline) doubled the risk of progression to RA. Total tenosynovitis Volume = incr. RA risk #EULAR2025 POS0472 https://t.co/eT0wbhp1uN

Hepcidin detected in synovial membrane and fluid in RA, PsA, and OA. Monocytes were the main source. IL-6, IL-10, IL-17, M-CSF induced hepcidin via JAK-STAT pathway. Hepcidin reduced osteoclastogenesis but correlated with synovial neutrophils and CXCL1 induction. Functional dual https://t.co/ZjUtTYPre8

VEGF-Grab (PB101/PB102), dual VEGF/PlGF decoy receptor, inhibited angiogenesis, RA-FLS invasion, and Th17 cell differentiation in RA and MS models. PB102 reduced IL-17 and GM-CSF co-expressing Th17 cells, suppressed pannus and joint destruction in CIA, and outperformed IFN-β in https://t.co/qhVRYT4RbK

2025 EULAR/ACR Risk Stratification Criteria for At-Risk Arthralgia
A collaborative EULAR/ACR expert panel has established criteria for arthralgia patients at risk (clinically suspect arthralgia) to progress to chronic rheumatoid arthritis (RA). Risk stratification of CSA https://t.co/xbgJHhPqcq

📊 In a 40-yr cohort (n=2818), RA pts had 2.3x ↑ risk of DVT (HR 2.26) & 1.6x ↑ risk of PE (HR 1.61) vs non-RA.
Risk ↑ with RF/CCP+, nodules (HR 2.9), BMI ≥30 (HR 1.9), & biologic use in year 1 (HR 2.4–2.9).
Remission = ↓ PE risk (HR 0.47)

POS0627: RA patients aged ≥90 yrs can benefit from biologics/JAKi! In 3,600 pts, 84% of those ≥90 achieved low disease activity, 71% were on JAKi. But serious infections occurred in 21%—mostly pneumonia. Use w/caution in the oldest-old. #EULAR2025 @rheumnow

#Probiotics +#methotrexate giving far more #remission in #rheumatoid #arthritis than #MTX alone?
Seems fishy….
oops - #fish #oil #omega3 #fatty #acids do work!
not sure re the huge benefit of ‘immunebiotics’

In propensity-matched RA cohort (n=2,449 each) on JAK inhibitors, adding a GLP-1 agonist reduced risk of: • Acute coronary syndromes (RR 0.65, p=0.0009) • DVT (RR 0.69, p=0.007) Overall CV events ↓ by 33% (RR 0.67, p=0.0007)

Can RA be intercepted?
In the ALTO follow-up of the APIPPRA RCT (Cope et al), 1 year of abatacept delayed RA onset by up to 3 years in ACPA+/RF+ individuals. Effect strongest in those with mature autoantibody profiles.

RA pts have ↑ risk of DVT (HR 2.26) & PE (HR 1.61) vs controls in this 40-year, pop-based study. Nodules, obesity, high disease activity & early biologic use ↑ risk. Remission in year 1 halved PE risk. VTE risk persists despite therapeutic advances.

A PT-led vocational intervention for RA/axSpA with reduced work ability was likely cost-effective: ↓€4,324 in societal costs & +0.05 QALYs over 12m vs usual care (95% probability at €20k/QALY). Results suggest cost-effective compared to usual care.

RA polygenic risk ≠ MI risk. In >8,700 Swedes w/ or w/o RA, higher genetic risk for RA wasn’t linked to higher MI incidence. Familial clustering of RA & MI likely driven by non-genetic factors. Traditional CV risk still key in RA care.

If you successfully taper off DMARDs in RA patients in remission, do you risk bringing new joints in the mix?
Leiden post-hoc trial: these patients don’t do worse than those who never get off drug.
Drug-free remission tricky but new joints not a worry. #EULAR2025 @RheumNow https://t.co/QDxNRPN9f1
