Expanding the IL-17 Therapeutic Landscape
IL-17 inhibitors are an effective therapeutic for a broad spectrum of inflammatory and autoimmune diseases and its blockade has revolutionized management of diseases such as psoriasis, psoriatic arthritis and SpA. Is there a need for more medications within the same therapeutic class?

Safety of Recombinant Zoster Vaccine in Rheumatic Patients
EurekAlert!
New work presented at the 2025 annual EULAR congress in Barcelona focuses on the recombinant zoster vaccine (RZV), which contains recombinant glycoprotein E – the major target of CD4+T-cells.

In 631 axSpA pts (mean age 33y, 54% female) from DESIR cohort, high-dose NSAID use (ASAS NSAID index ≥50) not associated with incident hypertension (HR 1.01; 95% CI 0.98–1.02) over 72 months. NSAID anti-inflammatory effect may offset BP risk in axSpA. Abstract#POS0256 @RheumNow https://t.co/ELYWoJDyKJ

In 4,121 SpA pts (mean age 45y; 61% male), composite scores w/ joint counts (DAPSA, DAS28, DAS44) best discriminated peripheral arthritis activity vs PGA & SJC alone. All scores had excellent construct validity; CRP weakest. Composite indices may optimize SpA assessment. https://t.co/oM97BEkkH5

In phase II/III trial (NCT04481139), ivarmacitinib 4mg significantly improved PROs in active ankylosing spondylitis: total back pain VAS (-25.6 vs -17.0), night pain (-25.0 vs -14.3), stiffness (-24.5 vs -15.8), PtGA (-23.8 vs -13.3), ASQoL (-3.2 vs -2.4). Benefits seen even https://t.co/RcJ5vfdoHf

In clinical practice, not all US enthesitis findings are SpA-specific. Enthesophytes/calcifications common in healthy pts. Inflammatory lesions (PD signal, erosions) at Achilles, distal patella & greater trochanter better distinguish PsA/axSpA. Target key sites to improve US https://t.co/jO61QjKfQp

In 581 PsA pts (EuroSpA), MRI showed axial SpA features in 31%: BME (69%), erosions (68%), fat lesions (58%). MRI-axPsA pts: younger (41y vs 46y), male (70%), HLA-B27+ (55%), ↑CRP (13 vs 7 mg/L). Radiographs identified sacroiliitis in 29%. MRI adds key detection. POS0297 https://t.co/nAw0BDAH22

In real-world PsA, IL-23 inhibitors (guselkumab/risankizumab) showed clinical response in axial/mixed PsA. Best response seen in pts meeting ASAS axial SpA criteria (RR 7.64) & baseline ASDAS-CRP >2.1. Supports role of patient stratification in axial PsA. Abstract#POS0113 https://t.co/qowZZmJOpM

Are we missing axial/SIJ lesions in PsA or are we misdiagnosing AxSPA + PSO pts for PsA?
5 register studies including 580+ pts w/ PsA/AxSPA+PSO
1/3 PsA routine care patients had SIJ MRI = SPA
29% Rx SII r-mNY criteria+
of which 38% MRI lesions AxSPA

‼️Diagnosis of axSpA is clinical
-MRI is a tool but still has a lot of limitations.
-Improve reports by directly communicating with radiology and be specific on pt clinical info.
-Unified algorithms are needed to apply AI in dx of SIJ inflammation on MRI.

🔍MRI lesions in early axSpA vs non axSpA with chronic back pain:
-Data from SPACE cohort

Difficult-to-Manage AxSpA: Global Prevalence and Associated Factors
The concept of D2M axSpA is a recent development, with the first expert consensus definition published by the Assessment of SpondyloArthritis International Society (ASAS) earlier this year. https://t.co/KmfJvAtwp0

#D2M_axSpA_saga 🇬🇷
Prevalence of D2M axSpA in 395 patients: 10.1%
Associated factors:
🔹️High disease activity at diagnosis
🔹️Comorbidities (high BMI, smoking, depression)
🔹️Unemployment

🚨Diagnostic delays are real in axSpA:
-Can lead to more extra-msk manfieststions (EMMs) in PsA and axSpA.
-Increases disease burden and productivity losses.
-EMMs can present before articular sx
-Uveitis and IBD associated with longer dx delays.
-Diagnosis has improved since https://t.co/rWMwG7Ewwe

📊 SIJ findings in PsA (n=581):
🧠 31% = MRI-confirmed axSpA
🦴 Only 29% met r-mNY criteria
MRI-axPsA group: younger, more male, HLA-B27+
Clinical + radiographic definitely underperform vs MRI

High dose NSAIDs and incidence of HTN in axSpA?
In pts with early axSpA(age at baseline 33.2 years) data from DESIR cohort showed that after adjusting for confounders,high dose NSAID use was not associated with incident hypertension (HR 1.01, 95% CI 0.98-1.02).

What is new in SpA?
‼️nomenclature change:
🚫AS≠ Ankylosing spondylitis
✅AS= Axial spondyloarthritis

Delay hurts.
Dx delay in axial SpA costs UK £3.1 billion annually.
Avg time to dx = 8.5 yrs
Avg dx cost = £187k/person
Fixing delay could save £167k/person.
Early Dx isn’t just better care—it’s economic policy.
