Background: ESPOIR is a longitudinal prospective cohort of adults with possible early RA (ClinicalTrials.gov: NCT03666091 ). Patients were referred by rheumatologists and general practitioners to one of the 14 regional centers in France. The objective and design of the cohort are described elsewhere (1). Patients received standard of care by their rheumatologists and were followed without predefined therapeutic strategies Objectives: To report the current 10-year outcome of patients with early rheumatoid arthritis (RA) in the ESPOIR cohort, and predictors of outcome. Methods: From 2003 to 2005, 813 patients were included if they had early arthritis (&lt; 6 months) with a high probability of RA developing and had never been prescribed disease modifying anti-rheumatic drugs (DMARDs). Multivariate logistic regression analysis was used to evaluate predictors of outcome. Results: In total, 521 (64.1%) RA patients were followed up for 10 years and 35 (4.3%) died, which appears similar to the French general population. Overall, 480 (92.1%) patients received a DMARD; 174/521 (33.4%) received at least one biologic DMARD, 13.6 and 23.4% within 2 and 5 years. At year 10 (Table), mean DAS28 ESR was 2.5 ± 1.3; 273 (52.4%) patients were in DAS28 remission, 39.7% in CDAI remission, 40.1% in DAS28 sustained remission, and 14.1% in drug-free remission. Disability was well controlled overtime (Figure) and half of the patients achieved a HAQ Disability Index &lt; 0.5; the SF-36 physical component and pain were well controlled. Structural progression was weak, with a mean change from baseline in modified Sharp score of 11.0 ± 17.9. A total of 82 (16.5%) patients required joint surgery including arthroplasty or arthrodesis in only 6.5% of the cases. A substantial number of patients showed new comorbidities, mainly cardiovascular or metabolic diseases over 10 years. Finally, positivity for anti-citrullinated protein antibodies was confirmed as a robust predictor of long-term outcome in patients with early RA. Table 1.

Conclusion: We report a very mild 10-year outcome of a large inception cohort of patients with early RA diagnosed in the early 2000s, which was much better than results for a previous cohort of early RA patients who were recruited in 1993. This current favourable outcome may be related to more intensive care for real-life patients than previously. References: [1]Combe B et al.
