Add-on certolizumab in pregnant women with APS
Women with antiphospholipid syndrome and lupus anti-coagulant are at high risk of developing adverse pregnancy outcomes (APO). Usual care includes low molecular weight heparin (LMWH) and low dose aspirin (LDA). Despite these therapies, APO have been reported up to 40%.

From Domains to Decisions: Personalizing PsA Care with Data
At EULAR 2025, Dr. Laura Coates (Oxford) took the plenary stage to reframe how we think about treating psoriatic arthritis. The message was clear: in 2025, PsA treatment is no longer about following a linear algorithm; it’s about understanding the unique constellation of domains, comorbidities, and patient factors that shape each clinical decision.

Secukinumab & Uveitis = Unclear? Post hoc study of 11 SEC RCTs finds lower uveitis risk in AxSpA (N 1980; SEC 150 1.29/100PYs vs 1.72/100PY in PBO), but not in PsA (N 2453; SEC 300 0.71/100PY vs zero w/ placebo) https://t.co/Gv9HheBU7l https://t.co/SlnrLRwmmn

Psoriatic Arthritis: Hit hard and Early
Two studies found no significant benefit of early biologics over standard methotrexate treatment, but they did not focus on poor prognosis cases. The SPEED trial, funded by the NIHR, aimed to compare disease activity in 192 PsA patients https://t.co/pS9DdOOVCV

Impact of TNFi on efficacy of Vunakizumab in AS.
-Post hoc analysis of Vunakizumab
(humanized monoclonal IgG1/k antibody targeting IL-17A) trial on AS pts.
-440 total pts, 163 had prior TNFi exposure
- At week 16, no significant differences in ASAS20 b/w TNFi exposed pts https://t.co/O9PFOuLa5l

In BIODOPT study (RA, PsA, axSpA), disease activity-guided tapering of biologics (incl. biosimilars) maintained QALY (Δ0.008, NS) while lowering biologic costs (Δ€–1,979 [95%CI –3,798;–161]) & total hospital costs (Δ€–1,936 [95%CI –3,753;–119]) over 18mo. Supports https://t.co/CJUpfU2oRA

Biologic switching in PsA:
-Retrospective study on 3,851 PsA pts initiating bDMARDs, 1,848 (48%) switched therapy at least once.
-TNFis were the initial therapy.
-IL17i were the first switch in both single-switch and multi-switch scenarios.
-Subsequent switches: back to TNFi https://t.co/tJDJvPeu9T

Data from COAST-V study (post hoc)
🔹️Ixekizumab in #axSpA
🔹️Efficacy stratified by CRP level
🔹️Better treatment response in the elevated compared to the normal CRP group

In RCT of RA pts in remission/low disease activity, spacing ozoralizumab (next gen TNFi) or reducing MTX led to more flares vs continued tx; but most pts in remission at baseline maintained LDAS.
Remission matters for subsequent Tx reduction.

Management and prognosis of RP by @Lupusreference
1. Pts with mild disease respond to GCs
2. NSAIDs/colchicine good alternatives
3. Most common biologics used: TNFi and IL6i
4. Consider CYP in life threatening dz/ICU pts
5. Dynamic CT assess tracheal collapse.
6. PET-CT can ≠ https://t.co/PNUecMZvkT

In the APEX Phase 3b RCT (N=1020), guselkumab (IL-23p19 inhibitor) significantly reduced radiographic progression (ΔvdH-S 0.55 & 0.54 vs 1.35 PBO; p≤0.002) and improved ACR20 (67–68% vs 47%) at W24 in biologic-naïve PsA. Safety consistent with prior data. Abstract LB0010 https://t.co/mFDsBsCg6m

👁️Uveitis in axSpA:
-Up to 40% can present before SpA dx
-NMA of 44 RCTs showed tx with TNFi, JAKi and IL-17i protective effects against uveitis
-Low rates of uveitis in axSpA pts on BIME trials suggests its possible beneficial effects.

Should we still be worried about lymphoma developing in RA patients?
Incidence has plummeted with modern therapy, although still a small risk. TNFi and other bDMARDs don’t seem to confer any real risk.
So what should our approach be?

In PsA, can we better pick IL-17A inhibitor responders (after TNFi failure)?
Transcriptomic profiling is going to get better at telling us which pathways are truly important for response to specific treatments
