What is the relevance of structural damage in psoriatic arthritis?

<p>In this episode of RheumaCast, we discuss the functional consequences of structural joint damage in psoriatic arthritis based on data from a large, prospectively followed cohort.</p><p>While inflammation is often considered the main driver of impaired physical function, this study provides a more nuanced view. Radiographic damage, particularly severe joint destruction, shows an independent association with functional impairment—even after adjusting for disease activity and other confounders. Importantly, not all damage is equal: mild or moderate changes appear to have limited functional impact, whereas complete joint destruction demonstrates a clear and clinically meaningful effect, with a dose–response relationship.</p><p>We also explore how these findings should influence treatment strategies, emphasizing early intervention and prevention of irreversible damage rather than relying solely on control of inflammatory activity.</p><p>This episode places structural damage into context and highlights its relevance for long-term patient outcomes in PsA.</p><p>This episode is based on publication Mehta P, et al. Arthritis Rheumatol 2026; doi:10.1002/art.70145 </p><p>and developed with NotebookLM.</p>
