Abstract | OBJECTIVES: To study whether disease status at treatment initiation has changed after the issue of the ASAS classification criteria. METHODS: REGISPONSERBIO registers patients with axial spondyloarthritis ( axSpA) on biological treatment since 2013. It includes patients starting biological treatment (incident) or already on biological therapies (prevalent). Patients in both groups were compared in terms of: age at disease onset and at treatment start, disease duration, gender, HLA-B27, body mass index (BMI), BASDAI, BASFI, C-reactive protein, ESR, metrological data, ASQoL, WAPAI, extra-articular manifestations, comorbidities, radiological study, type of biological treatment and concomitant treatments. RESULTS: 256 patients were included, of whom 174 (65%) were already on biologic therapy. Compared to incident patients, prevalent patients started treatment with longer disease duration (15 vs. 8.6 years; p<0.001), a higher proportion of them were men (83% vs. 67%; p=0.01), a smaller proportion of them showed non-radiographic axial spondylarthritis ( nr-axSpA)(17% vs. 32%; p<0.01), and a higher proportion had HLAB27 (85% vs. 73%; p=0.02). There were no statistically significant differences in terms of disease activity, degree of disability, quality of life, or prevalence of extra-articular manifestations. CONCLUSIONS: Data suggest that, after the issue of the new classification criteria for SpA, biological therapy is being administered earlier than previously in SpA patients and in a higher proportion of patients with nr-axSpA. However, this change in prescribing profile, apparently, has not caused an over-treatment, as patients do not seem to have a lower disease burden than prior to the issue of the criteria.
