RESUMO

OBJECTIVES: To analyse clinical severity/activity of rheumatoid arthritis (RA) according to smoking status. METHODS: The QUEST-RA multinational database reviews patients for Core Data Set measures including 28 swollen and tender joint count, physician global estimate, erythrocyte sedimentation rate (ESR), HAQ-function, pain, and patient global estimate, as well as DAS28, rheumatoid factor (RF), nodules, erosions and number of DMARDs were recorded. Smoking status was assessed by self-report as 'never smoked', 'currently smoking' and 'former smokers'. Patient groups with different smoking status were compared for demographic and RA measures. RESULTS: Among the 7,307 patients with smoking data available, status as 'never smoked,' 'current smoker' and 'former smoker' were reported by 65%, 15% and 20%. Ever smokers were more likely to be RF-positive (OR 1.32;1.17-1.48, p<0.001). Rheumatoid nodules were more frequent in ever smokers (OR 1.41;1.24-1.59, p<0.001). The percentage of patients with erosive arthritis and extra-articular disease was similar in all smoking categories. Mean DAS28 was 4.4 (SD 1.6) in non-smokers vs. 4.0 (SD 1.6) in those who had ever smoked. However, when adjusted by age, sex, disease duration, and country gross domestic product, only ESR remained significantly different among Core Data Set measures (mean 31.7mm in non-smokers vs. 26.8mm in ever smoked category). CONCLUSIONS: RA patients who had ever smoked were more likely to have RF and nodules, but values for other clinical status measures were similar in all smoking categories (never smoked, current smokers and former smokers).

RESUMO

OBJECTIVE: To analyse associations between the clinical status of patients with rheumatoid arthritis (RA) and the gross domestic product (GDP) of their resident country. METHODS: The Quantitative Standard Monitoring of Patients with Rheumatoid Arthritis (QUEST-RA) cohort includes clinical and questionnaire data from 6004 patients who were seen in usual care at 70 rheumatology clinics in 25 countries as of April 2008, including 18 European countries. Demographic variables, clinical characteristics, RA disease activity measures, including the disease activity score in 28 joints (DAS28), and treatment-related variables were analysed according to GDP per capita, including 14 "high GDP" countries with GDP per capita greater than US$24,000 and 11 "low GDP" countries with GDP per capita less than US$11,000. RESULTS: Disease activity DAS28 ranged between 3.1 and 6.0 among the 25 countries and was significantly associated with GDP (r = -0.78, 95% CI -0.56 to -0.90, r(2) = 61%). Disease activity levels differed substantially between "high GDP" and "low GDP" countries at much greater levels than according to whether patients were currently taking or not taking methotrexate, prednisone and/or biological agents. CONCLUSIONS: The clinical status of patients with RA was correlated significantly with GDP among 25 mostly European countries according to all disease measures, associated only modestly with the current use of antirheumatic medications. The burden of arthritis appears substantially greater in "low GDP" than in "high GDP" countries. These findings may alert healthcare professionals and designers of health policy towards improving the clinical status of patients with RA in all countries.

RESUMO

OBJECTIVE: To evaluate the quality of life and economic impact of switching therapy from infliximab to adalimumab in patients with rheumatoid arthritis (RA). METHODS: In this open-label study, patients demonstrating a clinical response to infliximab were switched to treatment with adalimumab and followed for 16 weeks. Both generic (Health Assessment Questionnaire and Short Form 36 Physical Component Summary and Mental Component Summary) and specific (Rheumatoid Arthritis Quality of Life questionnaire) assessment instruments of physical function and of quality of life were employed. An economic analysis of treatment-related costs was also performed. Disease activity was assessed by the composite 28-joint count Disease Activity Score (DAS28). C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were measured as acute phase markers. RESULTS: Nineteen patients were enrolled and completed the study. No changes in functional and quality-of-life measures were observed. One-year extrapolation data showed potential reductions in costs following switching to adalimumab that could be attributed primarily to reductions in patient- and staff-related costs. Safety and tolerability were similar for both treatments. Although there was a significant reduction in DAS28 (P < 0.005) and CRP (P < 0.001) after switching to adalimumab, there were no significant changes in individual DAS28 components, including swollen and tender joint counts and ESR. CONCLUSIONS: A switch from infliximab to adalimumab in patients with RA who have responded to infliximab is a feasible, well-tolerated treatment option, with the potential for direct and indirect economic advantages.

RESUMO

OBJECTIVE: The aim of this study was to characterize perceptions of health and well-being in women with established rheumatoid arthritis (RA). METHODS: Women aged between 40 and 60 yr with RA for more than 3 yr, and who were receiving stable doses of anti-rheumatic drug therapy, were selected for study. The Arthritis Impact Measurement Scales 2 (AIMS2) was employed to quantify current health status impairments, the impairments that were attributed to RA, perceptions of current health status compared with other women of the same age, and perceptions of future health status. RESULTS: Fifty-eight patients were studied. The full range of 12 AIMS2 dimensions was used when quantifying impairments in health status. The dominant impairment was pain. Moreover, 88% of patients attributed current pain to RA. Fifty-two per cent perceived their health status to be fair, poor or very poor compared with other women of the same age. Twenty-five per cent expected poor future health status, compared with 10% who perceived poor current health status. Only one patient (2%) expected excellent future health status. CONCLUSION: In this study, a large majority of women perceived impairments of health status that they attributed to RA. Pain was perceived as the predominant impairment. Deterioration in health status was anticipated by many. The inclusion of patient perceptions of health status and disease impact as outcome measures in both cross-sectional and longitudinal clinical research protocols merits further study.
