DISEASE COURSE IN EARLY RHEUMATOID ARTHRITIS: AN OBSERVATIONAL STUDY

Background. In rheumatoid arthritis (RA), prompt diagnosis and initiation of disease-modifying treatment during the first months after disease onset – a period called “window of opportunity” – is significantly superior to the delayed start of the same therapy. Clinical remission is more frequently obtained in patients with a disease duration no longer than 4 months and is the main aim of the treatment, therefore the “treat to target” (T2T) and “tight control” strategies were proposed. Objective. The aim of this study is to evaluate the therapy used for patients with early RA (ERA) and the impact of this medication on the clinical outcomes at 12 months after the first evaluation. Methods. Patients with early arthritis who were referred to the Early Arthritis Research Center of Dr. I. Cantacuzino Hospital between 2010-2014 and who fulfilled the 2010 EULAR/ACR Classification Criteria for RA (and who did not satisfy classification criteria for other inflammatory rheumatologic diseases) were enrolled. Only patients who received treatment with Methotrexate (MTX) associated or not with corticosteroids (CS) and patients who fulfilled the classification criteria for RA but did not received
