AB0761 Prevalence of Enthesitis and Dactylitis, Impact on Disease Severity and Evolution over 12 Months in PSA Patients Treated with Anti-TNF in A Real-World Setting

Background Spondyloarthritis, including psoriatic arthritis (PsA), is characterized by inflammatory arthritis affecting axial and peripheral joints. It is commonly associated with extra-articular and peri-articular manifestations (PAMs) including dactylitis and enthesitis. Objectives To evaluate the point prevalence of enthesitis and dactylitis at the time of anti-TNF initiation, their impact on disease severity, and their evolution over time in patients with active PsA treated in a routine clinical practice setting. Methods BioTRAC is an ongoing, prospective registry of patients initiating treatment for rheumatoid arthritis (RA), ankylosing spondylitis (AS), or PsA with infliximab or golimumab as first biologics or after having been treated with a biologic for
