Publisher Copyright: © 2025 The Author(s); Objectives: To develop a consensus-based expert definition of difficult-to-manage (D2M) axial spondyloarthritis (axSpA), incorporating treatment-refractory (TR) disease. Methods: A literature review was conducted in 2022 to identify potential definitions for D2M/TR axSpA from prior studies, followed by a 2-round Delphi consensus process conducted in 2022 and 2023 to id...

Published by BMJ.; OBJECTIVES: To follow up four previously identified classes 'pure axial spondyloarthritis' (axSpA) ('axial'), 'axSpA with peripheral signs' ('inflammatory back pain+peripheral'), 'axSpA at risk' and 'no spondyloarthritis' ('no SpA'). They reflect the expert-opinion-free ...

Published by BMJ.; OBJECTIVES: To investigate the associations between MRI detected vertebral corner inflammation (VCI) and vertebral corner fat deposition (VCFD) on whole spine low-dose CT scan (ldCT) detected syndesmophyte formation and growth.

This article is protected by copyright. All rights reserved.; OBJECTIVE: To test the impact of inflammation on MRI-structural changes occurring in the sacroiliac joints (SIJ) and the spine. METHODS: Patients with early axSpA from the DESIR cohort were included. MRIs of the SIJ (MRI-SIJ) and spine (MRI-spine), obtained at baseline, 2 and 5 years, were scored by 3 central readers. Inflammation and structural dama...
OBJECTIVE: To compare the sensitivity to change of different imaging scoring methods in patients with early axial spondyloarthritis (axSpA). METHODS: Patients from the DESIR cohort fulfilling the ASAS axSpA criteria were included. Radiographs and MRI of the sacroiliac joints (SIJ) and spine were obtained at baseline, 1, 2 and 5 years. Each image was scored by 2 or 3 readers in 3 separate 'reading-waves'. The ra...
Objectives: To characterise peripheral musculoskeletal involvement in patients with spondyloarthritis (SpA) including psoriatic arthritis (PsA), across the world. Methods: Cross-sectional study with 24 participating countries. Patients with a diagnosis of axial SpA (axSpA), peripheral SpA (pSpA) or PsA according to their rheumatologist were included. The investigators were asked which diagnosis out of a list of...
This article is protected by copyright. All rights reserved.; AIM: To investigate whether TNF inhibitors (TNFi) impact spinal radiographic progression in patients with axial spondyloarthritis (axSpA) and whether this is coupled to their effect on inflammation. METHODS: Patients with axSpA fulfilling the modified New York criteria were included in this prospective cohort (ALBERTA FORCAST). Spine radiographs, don...
Objective To identify clusters of peripheral involvement according to the specific location of peripheral manifestations (ie, arthritis, enthesitis and dactylitis) in patients with spondyloarthritis (SpA) including psoriatic arthritis (PsA), and to evaluate whether these clusters correspond with the clinical diagnosis of a rheumatologist. Methods Cross-sectional study with 24 participating countries. Consecutiv...
