Show moreWith the implementation of new treatment options, including biologicals and the early, agressive start of target-steered treatment the outlook for rheumatoid arthritis patients improved considerably the past decades. This thesis describes several aspects of modern rheumatoid arthritis treatment from the perspective of the BeSt study, a randomised controlled trial comparing four treatment strategies. The main findings from BeSt were that initial combination therapy, including high dose prednisone or the tumour necrosis factor inhibitor infliximab led to an earlier improvement in functional limitations and quality of life, earlier clinical remission and less joint damage after 5 years of follow-up than initial monotherapy. From one year onwards clinical outcomes were comparable across the groups. Drug free remission was possible in up to 20% of patients. Besides the primary outcomes of the BeSt study, this thesis de scribes the association between disease activity and functional capacity, the association between clinical signs of synovitis and joint damage progression at joint level, a comparison between disease activity measures and remission criteria, a comparison between radiological scoring methods, an evaluation of the effect of discontinuation of medication in case of low disease activity and remission and the association between disease activity, treatment and blood pressure.

Show moreMajor advances have been made in the treatment of rheumatoid arthritis, a potentially chronic disabling disease which poses a large burden on both patients and society. By early start of disease-modifying antirheumatic drugs, including methotrexate as a prominent drug, the use of combination therapies including prednisone or biologicals, and tight control of disease activity, many patients are able to reach a state of clinical remission and some can even taper and stop antirheumatic therapy. Challenges lie in correctly identifying the earliest manifestations of the disease, starting the right treatment sufficiently early, tailored to the individual patient, and setting the optimal treatment goal at which to steer therapy adjustments. This thesis has made a start towards tackling several of these challenges and discusses further necessary steps that may lead to a fundamental change in the outlook of patients with rheumatoid arthritis.

Show moreRA is a chronic and progressive autoimmune disease affecting approximately 1% of the population worldwide, and has a large risk for causing disability of patients and consequently high costs in health care if left un- or improperly treated. To prevent this, patients with RA need to be identified as early as possible and treated adequately to prevent worse outcome. Early recognition, together with prediction of the disease outcome at the individual patient level would allow to achieve personalized medicine. The main scope of this thesis was to identify and evaluate the quality of risk factors for their usefulness in predicting disease course and outcome of RA. To this end, characteristics and disease outcome of RA patients included in the Leiden EAC were studied. Show less
