A Disease Seeking Its Identity: Peripheral SpA, PsA, and the SPARTACUS Evidence

For years, peripheral spondyloarthritis has been managed with a cautious, stepwise approach: start with NSAIDs, escalate to conventional synthetic DMARDs, and only reach for biologics when everything else fails. The SPARTACUS trial, presented at EULAR 2026 in London, challenges that paradigm

Synovio-entheseal inflammation and the tipping point from PsO to PsA

Psoriatic arthritis develops in approximately 20 to 30 per cent of patients with psoriasis, yet predicting which patients will make the transition and when, has remained one of the most clinically challenging questions in rheumatology. A study presented at EULAR 2026 provides the most granular

Do probiotics help in #PsA? First RCT (MEDIPSA) says no. Multispecies probiotic vs placebo in 66 pts: 43% vs 65% achieved low disease activity at wk 12 (p=0.167). Gut-joint axis intriguing, but probiotics not the answer yet. @RheumNow #EULAR2026 POS0290

What does remission really mean to patients with #PsA? The RemiPPsA international qualitative study asked 123 patients across 11 countries. Pain-free + ability to resume daily life topped the list, not just composite scores. #EULAR2026 @RheumNow, POS0294 https://t.co/mEGpkewuTX
