Abstract: Despite conventional treatment, RA still has many deleterious consequences. From the patients' perspective, these include persistent pain, functional disability, fatigue, and depression modified by health beliefs and underlying psychological problems. Disability is a consequence of pain, active synovitis and joint damage. It is usually assessed by self-reported questionnaire; the Health Assessment Questionnaire (HAQ) remains the dominant disability measure, although generic health measures such as Short Form-36 and Nottingham Health Profile provide similar information. Treatment with disease modifying drugs and biologic agents improves pain, fatigue and disability. We specifically evaluated the effects of both these drugs and also disease duration on disability assessed by HAQ scores, as there is most information on this topic and it is of fundamental importance to patients. In early RA HAQ gives a 'J-shaped' curve; the initial fall is due to the immediate benefits of treatment and the subsequent gradual rise due to the inability of therapy to fully suppress the disease or prevent progressive joint damage. In established RA HAQ scores increase by about 1% annually and over 25 years average HAQ scores increase by 1.0. Disease modifying drugs and biologics both significantly reduce HAQ scores and the reduction is maintained for 2-5 years. This reduction is seen in both early and established disease. Early steroid therapy has immediate symptomatic treatment, but does not have long-term benefits. Over 5 years the impact of aggressive therapy with disease modifying drugs declines and there is evidence that insufficient treatment is given to many patients with RA. The outcome of RA is greatly improved by current treatment with disease modifying drugs and biologic agents. However, more needs to be done and achieving better results is enhanced by routinely measuring the impact of the disease in routine practice.

Abstract: PURPOSE OF REVIEW: The treatment of rheumatoid arthritis has been revolutionised in recent years with the advent of biologic treatments. The purpose of this review is to outline new treatments that target the inflammatory pathway in rheumatoid arthritis other than tumor necrosis factor-alpha. RECENT FINDINGS: As the use of anti-tumor necrosis factor-alpha treatment has become more widespread, the number of patients in whom this treatment is unsuccessful has also accumulated. Contraindications such as infection and cardiac failure further add to the number of patients who need alternative treatment. A better understanding of the inflammatory pathway in rheumatoid arthritis has led to interest in other therapeutic targets. Promising treatments such as interleukin-6 antagonists (MRA), CTLA4Ig (abatacept), and anti-B cell therapy (rituximab) have already been tested in randomized controlled trials over the past year. Other cytokines have been identified and have been shown to be of benefit in animal models, including interleukin-15, interleukin-17, and interleukin-18, and clinical trials of these agents are currently under way. SUMMARY: For patients with rheumatoid arthritis that does not respond to anti-tumor necrosis factor-alpha treatment, the promising alternatives MRA, abatacept, and rituximab have been tested. It is hoped that these agents will become available shortly.
