Description of intervention(s) / exposure
Treatment: Drugs - Methotrexate
Treatment: Drugs - Sulfasalazine
Treatment: Drugs - Other DMARDs
Experimental: Group 1 - Newly diagnosed RA patients started on subcutaneous MTX - open randomisation vs. sulfasalazine. In this group, use of NSAIDs, steroids, and/or other DMARDs, is allowed, if indicated, for symptom control. The overall management, tests and outpatient rheumatology visits schedule will be similar to other patients with RA, in accordance to standard practice .
Active comparator: Group 2 - Newly diagnosed RA patients started on sulfasalazine - open randomisation vs. subcutaneous MTX. In this group, use of NSAIDs, steroids, and/or other DMARDs (except MTX), is allowed, if indicated, for symptom control. The overall management, tests and outpatient rheumatology visits schedule will be similar to other patients with RA, in accordance to standard practice.
Experimental: Group 3 - RA patients on long-term treatment (\> 1 year) with oral MTX, with or without other DMARDs, NSAIDs and/or steroids, switched to subcutaneous MTX (same dose). In these patients, treatment with other DMARDs, NSAIDs and/or steroids will continue. The overall management, tests and outpatient rheumatology visits schedule will be similar to other patients with RA, in accordance to standard practice.
Active comparator: Group 4 - RA patients on stable treatment (\> 1 year) with other (non-MTX) DMARDs, with or without NSAIDs and/or steroids, and continued on the same treatment. The overall management, tests and outpatient rheumatology visits schedule will be similar to other patients with RA, in accordance to standard practice.
