SAT0044 Five-Year Favourable Outcome of Patients with Early Rheumatoid Arthritis in the 2000S: Data from the Espoir Cohort

Objectives To report the 5-year outcome of a large prospective cohort of patients with very early rheumatoid arthritis (RA), and to identify predictive factors of outcome. Methods Patients were recruited if they had early arthritis of less than 6 months’ duration, a high probability of developing RA, and had never been prescribed DMARDs or steroids. Patients were followed every 6 months during the first 2 years, then every year. Logistic regression analysis was used to determine predictive factors of outcome. Results 813 patients were included from December 2012 to april 2005: age was 48.1 ± 12.6 years, delay before referral 103.1 ± 52.4 days, DAS28 5.1 ± 1.3, HAQ 1.0 ± 0.7; 44.2 and 38.8% had IgM Rheumatoid Factor or anti-CCP2 antibodies; 22% had hands or feet erosions; 78.5% fulfilled the ACR/EULAR criteria for RA at baseline and 93.8% during follow-up. 573 patients were evaluated at 5 years. The outcome was mild for most patients: disease activity (median DAS28 2.5) and HAQ (median 0.3) were well controlled over time; 47.6% achieved DAS28 remission and 64.6% low disease activity in the first 2 years. Radiographic progression was low (2.9 Sharp unit / year). Only a few patients required joint surgery, but some developed new co-morbidities (eg, hyperlipemia, cardiovascular diseases). During the 5 years, 82.7% of patients had received at least one DMARD (methotrexate: 65.9%) usually as monotherapy, 18.3% a biological DMARD, and about 60% prednisone at least once (mean dosage 8.8 ± 7.7 mg/day). Anti-CCP2 antibodies was the best predictor of 5-year remaining in the cohort, prescription of synthetic or biologic DMARDs, and radiographic progression. Conclusions The generally good 5-year outcome of this cohort could be related to early referral, early effective treatment and close monitoring which are key processes in the management of early RA in daily practice.
