Abstract: OBJECTIVE: To investigate the validity, reproducibility, and responsiveness of a simplified power Doppler ultrasound (PDUS) assessment of joint inflammation compared with a comprehensive 44-joint PDUS assessment in patients with rheumatoid arthritis (RA) who started therapy with a biologic agent. METHODS: A total of 160 patients with active RA who started a biologic agent were prospectively recruited in 18 Spanish centers. The patients underwent clinical and laboratory assessment and blinded PDUS examination at baseline and 6 months. A PDUS examination of 128 synovial sites in 44 joints was performed. US synovitis and PD signal were semiquantitatively graded from 1 to 3 in all synovial sites. US count and index for synovitis and PD signal were obtained. PDUS intraobserver and interobserver reliability were evaluated. A process of data reduction based on the frequency of involvement of synovial sites by both synovitis and PD signal was conducted. Construct and discriminant validity of a simplified PDUS assessment was investigated. RESULTS: A PDUS simplified assessment including 24 synovial sites from 12 joints detected 100% of patients with synovitis and 91% of patients with PD signal. There was a highly significant correlation between the 44-joint count and index for synovitis and PD signal and the 12-joint count and index for synovitis and PD signal at baseline and 6 months (r = 0.84-0.90, P < 0.0005). The smallest detectable difference was lower than the mean change in simplified PDUS variables. CONCLUSION: A 12-joint PDUS assessment of RA joint inflammation may be a valid, feasible method for multicenter monitoring of therapeutic response to biologic agents.

Abstract: INTRODUCTION: We analyzed the prevalence of cardiovascular (CV) disease in patients with rheumatoid arthritis (RA) and its association with traditional CV risk factors, clinical features of RA, and the use of disease-modifying antirheumatic drugs (DMARDs) in a multinational cross-sectional cohort of nonselected consecutive outpatients with RA (The Questionnaires in Standard Monitoring of Patients with Rheumatoid Arthritis Program, or QUEST-RA) who were receiving regular clinical care. METHODS: The study involved a clinical assessment by a rheumatologist and a self-report questionnaire by patients. The clinical assessment included a review of clinical features of RA and exposure to DMARDs over the course of RA. Comorbidities were recorded; CV morbidity included myocardial infarction, angina, coronary disease, coronary bypass surgery, and stroke. Traditional risk factors recorded were hypertension, hyperlipidemia, diabetes mellitus, smoking, physical inactivity, and body mass index. Unadjusted and adjusted hazard ratios (HRs) (95% confidence interval [CI]) for CV morbidity were calculated using Cox proportional hazard regression models. RESULTS: Between January 2005 and October 2006, the QUEST-RA project included 4,363 patients from 48 sites in 15 countries; 78% were female, more than 90% were Caucasian, and the mean age was 57 years. The prevalence for lifetime CV events in the entire sample was 3.2% for myocardial infarction, 1.9% for stroke, and 9.3% for any CV event. The prevalence for CV risk factors was 32% for hypertension, 14% for hyperlipidemia, 8% for diabetes, 43% for ever-smoking, 73% for physical inactivity, and 18% for obesity. Traditional risk factors except obesity and physical inactivity were significantly associated with CV morbidity. There was an association between any CV event and age and male gender and between extra-articular disease and myocardial infarction. Prolonged exposure to methotrexate (HR 0.85; 95% CI 0.81 to 0.89), leflunomide (HR 0.59; 95% CI 0.43 to 0.79), sulfasalazine (HR 0.92; 95% CI 0.87 to 0.98), glucocorticoids (HR 0.95; 95% CI 0.92 to 0.98), and biologic agents (HR 0.42; 95% CI 0.21 to 0.81; P < 0.05) was associated with a reduction of the risk of CV morbidity; analyses were adjusted for traditional risk factors and countries. CONCLUSION: In conclusion, prolonged use of treatments such as methotrexate, sulfasalazine, leflunomide, glucocorticoids, and tumor necrosis factor-alpha blockers appears to be associated with a reduced risk of CV disease. In addition to traditional risk factors, extra-articular disease was associated with the occurrence of myocardial infarction in patients with RA.

Abstract: The objective of this study was to determine possible differences in the outcome of patients with rheumatoid arthritis (RA) with disease onset early and late in life. As part of a broader outcome study of RA which included patients seen in the division of Rheumatology of Hospital Universitario Marqués de Valdecilla of Santander, Cantabria (Northern Spain) with disease duration between 2 and 7 years, we selected patients with an age at disease onset of <or=45 or >or=65 years. The medical records of all eligible patients were reviewed for relevant clinical and laboratory variables; the patients were then further evaluated for disease activity using biological tests and joint indices such as joint counts and Thompson's Index, functional capacity using the American College of Rheumatology (ACR) functional classification (ACR-FC) and the modified Health Assessment Questionnaire (M-HAQ), and anatomical damage using the number of joint damage (NJD) and radiographs read by the Sharp's scoring method for joint erosion (JE), joint narrowing (JN), and overall. Patients in both subsets were then compared. For the multivariable analyses all patients in the original larger cohort were included, so that age could be used as a continuous variable and the power of the analyses could increase; 31 younger (mean age+/-SD: 36+/-7 years) and 35 older (73+/-6 years) patients were available for assessment. No differences in disease duration and gender distribution were observed. Likewise, both subsets had similar levels of disease activity, both articular indices, and biological markers. In contrast, elderly patients showed more functional limitations as per the M-HAQ [median (interquartile range): 0.4 (0.13-1.2) vs 0.13 (0-0.6), p=0.007] and greater anatomical damage as per the NJD [median (interquartile range): 2 (0-4) and 0 (0-2), respectively, p=0.04] and the JE, JN, and total Sharp Index score (p=0.001, 0.02, and 0.001, respectively). Although older patients took fewer disease-modifying antirheumatic drugs (DMARD) and combined DMARD treatments (2.5+/-1.4 vs 1.9+/-1.3, p=0.05 and 0.8+/-1.1 vs 0.3+/-0.6, p=0.01, respectively), multivariable analysis demonstrated an independent association between age at disease onset and the number of DMARD and functional and anatomical decline. Late-onset RA does not present a better prognosis than the early-onset form of the disease. At the very least the disease is comparable between both patient groups. However, disease compounded by age-associated factors may in fact have a worse prognosis late than early in life.

Abstract: The aim of this study was to study the short-term functional and anatomical prognosis of rheumatoid arthritis (RA) in a series of Spanish patients and to identify different subsets of patients as well as possible baseline factors associated with specific outcomes. All patients seen in our division who met the ACR criteria for RA and with disease duration between 2 and 7 years were eligible for the study. Available patients were further evaluated at the clinic for disease activity using biological tests and joint indices as joint counts and Thompson's index, functional capacity using the ACR functional classification (ACR-FC) and the modified Health Assessment Questionnaire (M-HAQ) and radiologic damage by the Sharp's radiologic scoring method. Cluster analysis was used to identify different clinical subsets of patients. One hundred and sixty-three patients were eligible for the study, 13 could not be located or refused to participate and 12 had died. Mean (+/-SD) age at disease onset and mean disease duration were, respectively, 56(+/-14) years and (55+/-20) months. Median (interquartile range) of M-HAQ was 0.4 (0.1-1.1) and 41% of patients were in III or IV ACR-FC. The majority of patients (93%) showed radiologic lesions and 65% had erosions. Cluster analysis identified three subsets: cluster I (70% of patients) was characterised by a good prognosis, cluster II (13%) by a high level of disease activity, and cluster III (17%) by a greater anatomic damage and longer disease duration. No baseline predictive markers were found for these different outcomes. We concluded that RA portends an overall poor short-term prognosis in a relative large percentage of our patients with significant anatomic and functional sequelae. Aggressive management is specially indicated in this subgroup of patients, although definitive prognostic markers for its early identification are still lacking.
