Prevalence and concordance of early and sustained remission assessed by various validated indices in the early arthritis "ESPOIR" cohort.

International audienceOBJECTIVES: To assess the prevalence of remission in early arthritis, to evaluate the concordance across different criteria sets in defining this state, and to look for predictive factors for early and sustained remission. METHODS: Patients from the ESPOIR cohort were followed-up every 6months. We analysed early remission and sustained remission in 3 groups of patients: patients having rheumatoid arthritis (RA) according to 2010 ACR/EULAR criteria, undifferentiated arthritis (UA), and the whole cohort.
