Abstract

Abstract : Background: Enthesitis is a common extra-axial manifestation in patients with axial spondyloarthritis (AxSpA) 1, 2 ; however, not much is known about the prevalence of enthesitis in AxSpA and its impact on disease burden in US real-world settings. Objectives: This study describes characteristics of patients with AxSpA who had enthesitis vs patients without enthesitis. Methods: This study included patients aged ≥ 18 years with AxSpA enrolled in the Corrona PsA/SpA Registry between March 2013 and August 2018. Enthesitis at enrollment was assessed via the Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index. Patient demographics, clinical characteristics, treatment profiles, disease activity, quality of life, and work productivity were compared between patients with and without enthesitis using t tests or Wilcoxon rank-sum tests for continuous variables and χ 2 or Fisher's exact tests for categorical variables. Results: Of 477 patients with AxSpA, 121 (25.4%) had enthesitis. Symptom and disease duration were similar between patients with and without enthesitis. In patients with enthesitis, a higher proportion were female, were more likely to have non-radiographic AxSpA and a history of depression, serious infections, and fibromyalgia vs those without enthesitis (all P < 0.05; Table 1 ). Current treatment with biologics or conventional synthetic disease-modifying antirheumatic drug (csDMARD) monotherapy was similar regardless of presence of enthesitis; however, patients with enthesitis were more likely to have prior csDMARD and biologic use, as well as current methotrexate use. Patients with enthesitis had worse disease activity (ASDAS, BASDAI, and BASFI scores; tender and swollen joint counts; physician global assessment; and DAPSA and cDAPSA scores), spinal mobility measures, quality of life (pain, fatigue, HAQ scores, and EQ VAS scores), and greater work impairment than patients without enthesitis (all P < 0.05; Table 2 ). Conclusion: Among patients with AxSpA in this US real-world study, the presence of enthesitis was associated with worse disease activity and quality of life compared to patients without enthesitis.
