🔬 Can baseline T cell phenotype predict PsA treatment response? COLIPSO cohort (n=17): YES! Higher Treg & activated CD4+ cells predict DAPSA & joint improvement #POS0083 #EULAR2026 @RheumNow https://t.co/UIs6LXAWAY

Window of opportunity in stills disease is early. With IL1 / IL6 agents #sJIA and #AOSD are the same disease. - may need a standard new crieteria IL18 measuremnet should be encouraged. @RheumNow #EULAR2026 plenary https://t.co/EQbs9mDYjS

Who should we screen for RA-ILD? RA-ILD remains a serious extra-articular manifestation, contributing to morbidity and mortality. At #EULAR2026, two abstracts shed light on clinical phenotyping and risk profiling. Read my report for @RheumNow: https://t.co/CTtYHINXxU

🧬 Do biomarkers predict #zasocitinib response in PsA? YES: TYK2/IL-17 pathway markers predict ACR20 in 290pts Phase 2b RCT #OP0184 #EULAR2026 @RheumNow https://t.co/AVlyrauI5q

🔎 Can US predict PsA progression from psoriasis? YES: synovio-entheseal inflammation predicts progression in 183pts prospective cohort #OP0183 #EULAR2026 @RheumNow https://t.co/7B9KU60qFd

DESIR Cohort 10-year data (OP0102): SIJ structural lesions in #axSpA progress slowly, but prior MRI bone marrow oedema predicts later structural damage. bDMARD exposure was associated with less erosion progression supporting early biologic treatment Abstr OP0102 @RheumNow

#EULAR2026 OP022 We need to think beyond proteinuria to assess activity & response in #lupusnephritis. ReBioLup study showed 67% of patients with persistent histologic activity at 12 months (NIH=>4) still met criteria for complete clinical response @RheumNow https://t.co/bRFNrNLjJX

#EULAR2026 OP0228 Is there “something in the air?” Data from US Market Scan: poor quality index was associated with increased risk of #SLE. Although causal inference cannot be deduced, seems an important environmental factor. To check air quality assoc with UV index @RheumNow https://t.co/1FOw7RDA9a

Which ‘CAR’ to drive in #SLE? Comparison of #CD19 #CAR-T #allogenic vs #Autologous ➡️ comparing #molecular #responses from 2 #lupus studies N=12 Both improved cytokine signatures For #IFN & #neutrophils Results similar not identical ?either #POS0678 #EULAR2026 @RheumNow https://t.co/Lcpv3qJ6tU

#OP006 - Urine proteomics in LN tracks histo activity & treatment response better than proteinuria. Paired biopsies linked active disease to IFNI, IL12, complement & neut pathways- normalised in responders but persisted in non-responders. @RheumNow #EULAR2026 #EULARBest #Plenary

🔬 Does synovial biopsy-guided treatment outperform standard care in PsA? YES - 68% vs 45% DAPSA remission/LDA in 45pts OP071 #EULAR2026 @RheumNow https://t.co/cLCR7I8QAm

#EULAR2026 OP002 In 20 active #lupus nephritis patients with paired kidney biopsy at baseline & 1 yr, urine proteomics showed histology response correlated with restoration of immune, coagulation and ECM-remodelling pathways.

#EULAR2026 OP0125 It’s a case of “teamwork makes the dream work!” Instead of an index to capture heterogeneity in #Sjogren activity, the NECESSITY validated using data from 16 RCTs that a new composite tool, STAR has high sensitivity & specificity.

Psoriatic arthritis #PsA sessions raised important topics on intercepting arthritis in psoriasis, treating obesity as a disease target, synovial biopsy to guide treatment, molecular imaging to reveal subclinical disease. More tomorrow. #Rheumatology @RheumNow #EULAR2026

#OP088 at #EULAR2026 found that rare deleterious variants in telomere-related genes were associated with increased RA-ILD risk, independent of MUC5B status. The effect size was similar to that seen in idiopathic pulmonary fibrosis. @RheumNow

Multiparametric renal MRI in LN: Structural MRI can differentiate bet. active and stable dse Exudative = active inflamm In quanti analysis, low ADC values may reflect fibrosis. A potential non-invasive biomarker? OP092 @rheumNow #EULAR2026 https://t.co/IarTGOen7v
#OP087 explored cancer polygenic risk scores (PRS) in RA. RA was assoc with lower risks of breast and colorectal cancer across all PRS categories, while high prostate cancer PRS may identify RA patients with increased early prostate cancer diagnoses. @RheumNow #EULAR2026 https://t.co/WMqqSFADlW

Kicking off Clinical Abstracts: Comorbidities in RA session at #EULAR2026 with #OP084 ANCHOR-RA found 9.1% at-risk RA patients had previous undiagnosed ILD on screening HRCT. Older age, smoking, male sex & ⬆️DAS28 linked to RA-ILD. Important data for earlier detection @RheumNow

Progress of biologics/targeted therapy in SLE

We are in a transformative era in SLE which generates excitement to both physicians and people living with lupus. We now have four licensed biologics/targeted therapies (i.e., belimumab, voclosporin and obinutuzumab for active lupus nephritis, and belimumab and anifrolumab for active non-renal
