#EULAR2026
PMR/GCA reccs:
1. Refer to a specialist with expertise
2. For GCA- start steroids without delay
3. PMR pred dose 15-25 mg/d taper to 10 mg/d in 1 year (for major relapse treat like new onset, for minor relapse, increase to last effective dose

At #EULAR2026 we presented our work OP071 on synovial biopsy–driven therapeutic stratification in #PsoriaticArthritis.
Our preliminary data suggest that CD117+ myeloid synovitis may support IL-17/IL-23 axis targeting in selected PsA patients.

REPLENISH phase 3 in relapsing PMR: 🔹secukinumab 150/300 mg doubled 🔹sustained remission at Week 52 vs placebo ➡️ 40–41% vs 20%, p<0.001 🔹improved complete sustained remission ➡️25–28% vs 5%.
🔹GC-sparing effect, with no new safety signals. #EULAR2026 #PMR

🧩 #ACR25 Highlight | Skin in the Game: Cutaneous Clues in Rheumatic Disease
By Dr. Katharina S. Shaw, Penn Medicine
🧵 Post 1 | Eosinophilic Fasciitis vs Systemic Sclerosis
• 💡 Check distal digits → tightening absent in EF, universal in SSc
• ✴️ Groove sign & “pseudocellulite” = EF clues
• ❌ Raynaud’s & nailfold capillary changes → SSc hallmark
• 🩸 MRI ≈ biopsy for diagnosis
• 💊 Tx: Pulse IV methylpred → PO taper + MMF ± IVIg
• ⏱ Delay > 6 mo → 14× poorer outcome

#ReviewCourse #ACR25 MAS treatment:
🔹Corticosteroids remain first-line
🔹 Anakinra (anti-IL1) improve survival in severe MAS
🔹 Emapalumab (anti-IFNγ) 93% remission in refractory cases; FDA-approved for steroid-refractory Still’s-MAS

#ReviewCourse #ACR25 vasculitides & CNS involvement
🔹 Takayasu,PAN & ANCA-associated: CNS dysfunction rare but life-threatening.
🔹 GCA/PMR:overlapping inflammatory spectrum.
🔹 Behçet’s: parenchymal vs. cerebral venous thrombosis forms.
💊 Therapy: cyclophosphamide or TNF/IL-6

🧯How to treat Macrophage Activation Syndrome in 2025
🔴Take-home points from Dr Nigrovic's talk on Still's Disease
1- Methylprednisolone + Anakinra
2- + Ruxolitinib
+/- Tacrolimnus / IVIG / Rituximab
3- Emapalumab
4- Etoposide + Dexamethasone

New systematic review by @sinisauksav et al. characterises the complete phenotypic spectrum of VEXAS syndrome.
➡️These findings will facilitate earlier diagnosis, inform monitoring strategies, and guide future research priorities.

What's the difference between PIPsA & NIPsA?
(Persistent Inflammatory confirmed by IMAGING
vs. Non inflammatory PsA)
🔹️Cross-sectional study
🔹️517 pts under b/tsDMARDs
🔹️10.3% D2T
🔹️57% PIPsA / 43% NIPsA
👇 Distinct phenotypes 👇

Prédiction of PsA from PsO. Stockholm cohort, n=672):
•PsA incidence 21.1/1000 PY.
•AUC 0.80 for both referral and prognostic models.
•Predictors: HLA-B27, uveitis, enthesial pain, TJC, hsCRP, BMI, SAA, GlycA.
•Early identification feasible.

🚨 Mind-blowing insights from Georg Schett at #EULAR2025:
CAR-T in autoimmune diseases is no longer experimental — it’s revolutionizing care.
✅ Immune reset → drug-free remission
✅ Efficacy in highly-resistant AID
✅ Allogenic & “armed” #CAR_T moving fast into clinics
