Comparison of the long-term outcome for patients with rheumatoid arthritis with persistent moderate disease activity or disease remission during the first year after diagnosis: data from the ESPOIR cohort.

OBJECTIVE: To investigate if patients with early RA with persistent moderate disease activity during the first year after diagnosis have a worse 3-5 year outcome than those who achieve sustained clinical remission within the first year, in a daily life setting. METHODS: The ESPOIR cohort included patients with early arthritis of <6 months' duration. Treatment was the standard of care. We had 5-year follow-up data for 573 patients. This study compared patients who had persistent moderate disease activity (Disease Activity Score in 28 joints (DAS28)>3.2 and ≤5.1) at both the 6- and 12-month visits, with those who were in sustained DAS28 remission. The primary outcome was radiographic progression at the 36-month visit. Secondary endpoints were clinical remission (DAS28 score, Simplified Disease Activity Index, ACR/EULAR criteria), Health Assessment Questionnaire-Disability Index (HAQ-DI) and number of missed workdays at months 36 and 60. A Fisher exact test was used to compare categorical variables, and the Kruskal-Wallis test for quantitative variables. Logistic regression analysis was used to determine predictors of outcome. RESULTS: Patients were aged 48.1±12.5 years and their duration of symptoms was 103.2±52.1 days. Mean baseline DAS28 was 5.1±1.3. Persistent moderate disease activity (107 patients) rather than sustained remission (155 patients) during the first year was associated with increased radiographic disease progression at 3 years (OR=1.99 (95% CI 1.01 to 3.79)), increased HAQ-DI at 3 and 5 years (5.23 (2.81 to 9.73) and 4.10 (2.16 to 7.80), respectively), a 7-11 times smaller chance of achieving clinical remission and a five times greater number of missed workdays. CONCLUSIONS: Patients with early RA with persistent moderate disease activity during the first year had a worse outcome than patients who achieved sustained clinical remission. Persistent moderate disease activity affects long-term structure, remission rate and functional and work disability. Such patients may benefit from intensive treatment.

Clinical and ultrasound-based composite disease activity indices in rheumatoid arthritis: results from a multicenter, randomized study.

OBJECTIVE: To evaluate the metrologic properties of composite disease activity indices in rheumatoid arthritis (RA), utilizing information derived from clinical, gray-scale (GS), and power Doppler (PD) ultrasound examinations, and to assess the classification of patients according to disease activity using such indices. METHODS: This ancillary study utilized data from a multicenter, prospective, randomized, parallel-group study conducted in subjects with moderate RA randomized to receive etanercept and methotrexate (ETN + MTX) or usual care (various disease-modifying antirheumatic drugs [DMARDs]). In multimodal indices, the 28 swollen joint count was either supplemented or replaced by clinically nonswollen joints in which the presence of synovitis was detected either by GS and/or PD and was calculated according to the Disease Activity Score in 28 joints (DAS28) or the Simplified Disease Activity Index (SDAI). Reliability, external validity, and discriminative capacity were calculated at baseline/screening by intraclass correlation coefficient, Pearson's correlation, and standardized response mean, respectively. RESULTS: Data from 62 patients (mean ± SD age 53.8 ± 13.2 years, mean ± SD disease duration 8.8 ± 7.7 years, mean ± SD disease activity 4.6 ± 0.5 [DAS28] and 20.9 ± 5.9 [SDAI]) were analyzed, with 32 receiving ETN + MTX and 30 receiving DMARDs. The metrologic properties were at least as good for GS- and/or PD-based indices as for their clinical counterparts. Using GS- and PD-supplemented indices, an additional 67.8% and 32.3% of patients (DAS28-derived and SDAI-derived indices, respectively) could be classified as having high disease activity at the screening visit. CONCLUSION: Multimodal indices incorporating ultrasound and clinical data had similar metrologic properties to their clinical counterparts; certain indices allowed for a significantly larger number of patients to be classified to either high or moderate disease activity at the screening visit.

Efficacy of etanercept on rheumatic signs and pulmonary function tests in advanced ankylosing spondylitis: results of a randomised double-blind placebo-controlled study (SPINE).

OBJECTIVES: Patients with advanced ankylosing spondylitis (AS) experience disability because of reduced spinal mobility and pulmonary function impairment. This placebo-controlled study evaluated the effect of etanercept (ETN) in patients with advanced AS. METHODS: A multicentre randomised double-blind placebo-controlled trial of 12 weeks' duration was performed. Patients had definite (modified New York criteria), active (Bath AS Disease Activity Index (BASDAI) ≥40), severe (radiological intervertebral bridges) AS refractory to non-steroidal anti-inflammatory drugs and were antitumour necrosis factor naive. They were treated with ETN 50 mg once weekly or identical placebo (PBO). RESULTS: Of the 95 patients screened, 82 were randomised to receive ETN (n=39) or PBO (n=43). At baseline the disease was active (mean BASDAI 61.0±13.4, C reactive protein (CRP) 20.7±25.5 mg/l) and severe (mean Bath AS Metrology Index (BASMI) 5.7±1.3, mSASSS 36.5±20.5); forced pulmonary vital capacity (FVC) was 3.3±0.7 l. Improvement in BASDAI (normalised net incremental area under the curve between baseline and week 12, primary end point) was significantly greater in the ETN group than in the PBO group (-19.8±16.5 vs -11.0±16.4, p=0.019). Moreover, at week 12, ETN gave better results than PBO for the BASDAI (-26.4±19.7 vs -14.4±19.7; p=0.008), total back pain (-29.2±24.0 vs -14.9±24.0; p=0.010), BASFI (-21.7±17.6 vs -10.1±17.6; p=0.004), BASMI (-0.6±0.6 vs -0.2±0.6; p=0.011), CRP level (-15.7±14.2 vs -1.3±14.2; p<0.001) and FVC (+160±280 ml vs -20±280 ml; p=0.006). CONCLUSIONS: ETN has short-term efficacy for patients with advanced AS, as was previously reported for less advanced disease. The efficacy is observed for the main symptoms (pain) and on markers of inflammation (CRP), as well as disease severity in terms of spinal mobility and pulmonary function.

[Arteriovenous malformations: a study of 200 cases]. / Malformations artérioveineuses: étude de 200 cas.

OBJECTIVE: The aim of this study was to analyze the natural history of arteriovenous malformations by reviewing 200 consecutive cases observed in all localizations between 1992 and 1996 in a multidisciplinary angioma clinic. PATIENTS AND METHODS: Files concerning 200 arteriovenous malformations were reviewed with a standardized observation sheet applying the severity criteria defined by the International Society for the Study of Vascular Anomalies. We used the Schobinger staging system which includes 4 grades of severity: grade I=dormancy, grade II=expansion, grade III=destruction, grade IV=cardiac decompensation. RESULTS: There was no predominance by gender. Cephalic localizations were the most common. The malformation was present at birth as indicated by history taking in 40 p. 100 of the cases. Progression during childhood (grade II) was observed in 84 p. 100. At the first consultation, the patients generally were more often in grade II than in grade I or III. Bone destruction was observed in 3 cases, signs of cardiac decompensation in 5. Arteriovenous malformations were part of a more complex syndrome in 9 cases. We noted a flare-up in the prepuberty or puberty period in 75 p. 100 of the cases and the possible role of puberty (64 cases), trauma (39 cases) and pregnancy (25 p. 100 of the adult women). Explorations were generally completed (Doppler, arteriography) by grade II, expressing the need for a map of expanding lesions. Finally it was difficult to assess posteriorly the beneficial or deleterious effect of the often multiple treatments prescribed for these patients. DISCUSSION: The review of these 200 cases pointed out the "pediatric" nature of the problem of arteriovenous malformations in the large majority of the cases and the often misleading presentation of these vascular anomalies, particularly grade I malformations. A false aspect of capillary malformation could raise the risk of inappropriate treatment. This review also confirmed known factors of exacerbation (puberty, pregnancy, trauma) and demonstrated the severity of these vascular anomalies which can progress with loco-regional expansion and invasion without a cellular proliferation component. The analysis of treatments used showed that embolization alone cannot definitively and totally control a superficial arteriovenous malformation and that no one treatment, even combined embolization and large excision, can be a guarantee to provide total cure.
