The ARCTIC-FORWARD study is a multi-center prospective observational study investigating the long-term outcomes of rheumatoid arthritis (RA) patients who received structured treat-to-target therapy early in their disease. The main hypothesis of this project is that RA treat-to-target strategies during the first two years of disease result in beneficial long-term outcomes both with regards to joint damage, disease activity and societal costs.
Rheumatoid arthritis (RA) is one of the most common autoimmune diseases. Recent developments in RA treatment has shown to change the outcome of RA for the early stages of the disease, with very limited loss of work participation and high rates of disease activity remission. The data on the long-term outcome for patients who received early optimal treatment is much more limited, and it is of special clinical interest to know to what extent these patients should be monitored with regards to slowly evolving joint damage, subclinical inflammation, loss of physical function and loss of work participation.
The aim of this study is to assess clinical, radiographic and functional long-term outcomes of modern RA care and to identify risk factors for progressive disease.The main hypothesis of this project is that RA treat-to-target strategies during the first two years of disease result in beneficial long-term outcomes both with regards to joint damage, disease activity and societal costs. We will perform an extensive evaluation of all patients participating in the ARCTIC study 10 years after the initiation of structured treat-to-target therapy. Outcomes include disease activity, radiographic damage, functional status, DMARD use, extra-articular manifestations including interstitial lung disease, comorbidities, survival, work participation, health care resource use, and health related quality of life.
