We want to study, whether early treatment with infliximab for 6 months started parallel with the combination therapy of methotrexate, sulphasalazine, hydroxychloroquine and prednisolone (COMBI) can induce quick remission in patients with early RA, if the remission can be sustained after 6 months on patients continuing the COMBI treatment and can diminish the risk of progression of erosive changes in patients with early RA, and if we can reduce costs of the 2 treatment arms with respect to costs due to the disease.
