| ORAL 0854 | Monday, 27.10.25 9:15 Plenary Session: Plenary Session II Presenting author: Maksymowych, W (Canada) Title: The ASAS-SPARTAN revised classification criteria for axial spondyloarthritis: development and validation in the Classification of Axial SpA (CLASSIC) Inception Cohort  An international study (CLASSIC cohort, 61 centers) established new classification criteria for axSpA that improve upon the 2009 ASAS criteria. In 1,015 patients (37% with axSpA), the 2009 criteria fell short of the target performance (sensitivity 82.4%, specificity 77.1%) The revised criteria place greater weight on imaging—MRI of the SI joints (active + structural lesions) was the strongest predictor, followed by radiographic sacroiliitis. |

In a case–control analysis (109 axSpA patients – including radiographic and non-radiographic – vs 51 mechanical back pain), the 14-3-3η AAb assay showed good diagnostic performance (ROC AUC ~0.77 overall; 0.78 for AS, 0.73 for nr-axSpA). |
| ORAL 2692 | Wednesday, 29.10.25 12:45 Abstract Session: Spondyloarthritis Including Psoriatic Arthritis – Treatment II: Pathogenesis, Exercise, and Dietary Interventions Presenting author: De Mits, S (Belgium) Title: Individualized Strength, Mobility and Aerobic Rehabilitation Training in axial Spondyloarthritis (iSMART in axSpA) In this study, 30 axSpA patients underwent tailored, supervised training combining aerobic conditioning with targeted trunk strengthening and mobility exercises. Post-intervention, objective measures of physical function improved significantly: trunk muscle strength increased by ~14% and spinal mobility by ~15% on average (both p < 0.001). Disease activity and mobility outcomes showed parallel benefit – BASDAI dropped from 3.5 to 2.9 (p = 0.021). |
| POSTER 2359 | Tuesday, 28.10.25 10:30 Poster Session C: Spondyloarthritis Including Psoriatic Arthritis – Treatment Poster III Presenting author: Konsta, M (Greece) Title: Combination Of TNF Inhibitors And NSAIDs Versus TNF Inhibitors Alone On The Progression Of Structural Damage In The Spine And Hip: a Retrospective Study In 262 Patients With Radiographic Axial Spondyloarthritis This multicenter retrospective study suggests that adding continuous NSAIDs to TNF inhibitor therapy may slow long-term spinal radiographic progression in AS. Co-therapy was associated with significantly less new syndesmophyte formation (36% of patients on TNF + NSAID vs 58% on TNF alone; p = 0.001). |
| POSTER 0584 | Sunday, 26.10.25 10:30 Poster Session A: Spondyloarthritis Including Psoriatic Arthritis – Treatment Poster I Presenting author: Garcia-Salinas, R (Argentina) Title: Difficult-to-Manage Axial Spondyloarthritis According to ASAS Criteria in Reuma-Check Cohort: Frequency, Predictive Factors, and Treatment Patterns. This study underscores that about 9% of axSpA patients have difficult-to-control disease. A combination of clinical markers (e.g. psoriasis, structural damage) and advanced imaging (ultrasound) can help identify these high-risk patients early, guiding clinicians toward timely multi-modal interventions. |
| ORAL 0888 | Monday, 27.10.25 10:45 Abstract Session: T Cell Biology & Targets in Autoimmune & Inflammatory Disease Presenting author: Adam S. Weinheimer (USA) Title: TargetScan Platform Identifies Targets of CD8+ T cells in Ankylosing Spondylitis and Birdshot Uveitis The study used TScan’s high-throughput TargetScan platform to discover natural Class I–restricted autoantigens recognized by CD8⁺ T cells in ankylosing spondylitis (AS) and birdshot uveitis (BU). These findings provide new insight into the antigenic drivers of AS/BU and lay a foundation for antigen-specific tolerizing therapeutics. |
