    Background: Early suppression of disease activity in (rheumatoid) arthritis (RA) patients may result in drug-free remission and prevent damage. We assessed 2-year clinical and radiological outcomes of two disease activity score (DAS)-remission-steered treatment strategies in early arthritis patients.Methods: Patients (n = 610) with early RA or undifferentiated arthritis (UA) were treated with methotrexate (MTX) and tapered high dose of prednisone. Patients in early remission (44/53 joints DAS <1.6) after 4 months tapered and stopped medication. Patients who did not achieve early DAS-remission were randomized to either MTX plus hydroxychloroquine plus sulphasalazine plus low dose prednisone (arm 1) or to MTX + adalimumab (arm 2). At four-monthly intervals, medication was tapered and stopped if DAS was <1.6 but restarted, increased or switched if DAS was ≄1.6. Proportions of (drug-free) DAS-remission (DFR) after 2 years and Sharp-van der Heijde scores (SHS) were analyzed separately for the treatment strategies and patients with RA and UA.Results: After 2 years, 301/610 (49 %) patients were in DAS-remission and 131/610 (21 %) in DFR. In the early remission group 241/387 patients (62 %) were in DAS-remission and 111/387 (29 %) DFR. In arm 1 22/83 (27 %) and in arm 2 24/78 (31 %) were in DAS-remission, and 6/83 (7 %) and 7/78 (9 %), respectively, were in DFR. RA and UA patients achieved DAS-remission in comparable percentages (RA: 234/479 (49 %), UA: 64/122 (52 %), p = 0.25). More UA patients achieved DFR (41/122 (34 %)) compared to RA patients (89/479 (19 %), p<0.001). Mean (SD) DAS over time was 1.74 (0.58) across all patients, and median (IQR) SHS progression was 0 (0–0).Conclusions: After 2 years remission-steered treatment in early RA and UA patients, DAS-remission and DFR percentages were relatively low. Patients who achieved early remission more often achieved (drug-free) remission after 2 years than patients who needed additional treatment steps in the randomization arms, and more UA than RA patients achieved DFR. Overall, disease activity and radiologic damage progression in all patients were well suppressed.Trial registration: http://www.controlled-trials.com/ISRCTN11916566 Registered 07/11/2006 and EudraCT number 2006-06186-16 Registered 16/07/2007

    Objective: It is generally thought that causes of undernutrition are multifactorial, but there are limited quantitative studies performed. We therefore examined a wide range of potential factors associated with undernutrition in communitydwelling older adults. Design: Cross-sectional study. Setting: Community-dwelling older adults (>= 65 years) receiving home care in the Netherlands. Subjects: Data on potential factors associated with (risk of) undernutrition were collected among 300 older adults. Nutritional status was assessed by the SNAQ(65+) instrument. Undernutrition was defined as mid-upper arm circumference = 4 kg in 6 months. Being at risk of undernutrition was defined as having poor appetite and inability to walk up and down stairs of fifteen steps, without resting. Results: Of all participants, ninety-two (31.7%) were undernourished and twentyfour (8.0%) were at risk of undernutrition. Based on multivariate logistic regression analyses, the statistically significant factors associated with (risk of) undernutrition (P <0.05) were: unable to go outside (OR=5.39), intestinal problems (OR=2.88), smoking (OR =2.56), osteoporosis (OR=2.46), eating fewer than three snacks daily (OR=2.61), dependency in activities of daily living (OR=1.21), physical inactivity (OR=2.01), nausea (OR=2.50) and cancer (OR=2.84); a borderline significant factor was depression symptoms (OR =1.83, P=0.053). Conclusions: The study suggests that (risk of) undernutrition is a multifactorial problem and that associated factors can be found in several domains. These findings may support the development of intervention trials for the prevention and treatment of undernutrition in community-dwelling older adults

    OBJECTIVE: Novel activation products that are stable and minimally susceptible to in vitro artefacts have recently been described in the classical complement pathway. The present study assessed circulating levels of these products, i.e., covalent complexes between the recognition molecule of the classical pathway (C1q) and activated C4, in plasma samples from patients with rheumatoid arthritis (RA) to establish the relationship between these levels and the clinical and immunologic parameters in these patients. METHODS: C1q-C4 levels were measured in plasma samples from 41 patients with active RA and 43 patients with inactive RA. These levels were related to other complement activation products and to disease activity according to the Disease Activity Score in 28 joints (DAS28), using Spearman's rank correlations. RESULTS: C1q-C4 plasma levels were significantly higher in patients with active RA as compared with patients with RA in clinical remission (median 3.3 arbitrary units [AU], range 0.4-13.4 versus 1.7 AU, range 0.2-5.5; P=0.0001), suggesting that activation of the classical complement pathway reflects disease activity. This was supported by a significant correlation between C1q-C4 levels and the DAS28 (r=0.398, P=0.0002). Levels of other complement activation products, such as activated C4 (C4b/c), were also significantly elevated in patients with active disease compared with patients with inactive disease (P=0.03), and were correlated with C1q-C4 levels (r=0.329, P=0.002). Levels of C1q-C4 complexes were higher in synovial fluid samples than in plasma samples from the 4 patients tested. CONCLUSION: Systemic complement activation via the classical pathway in patients with RA correlates with disease activity. These results indicate that C1q-C4 complexes may be used as a biomarker for R

    To assess whether radiologic progression occurs during clinical remission in patients with rheumatoid arthritis (RA). One hundred eighty-seven patients with RA in clinical remission were followed up clinically and radiologically for 2 years. Clinical remission was defined according to a modification of the American College of Rheumatology criteria (i.e., the criterion of fatigue was omitted, and patients had to fulfill 4 of the 5 remaining criteria). Radiologic joint damage was assessed by the Sharp/van der Heijde method. After 2 years of followup, remission persisted in 52% of patients. The median radiologic score for the total group of patients increased from 21 (interquartile range [IQR] 5, 65) at the time of entry to 25 (IQR 7, 72) after 2 years (P <0.001). The median score for radiologic progression between baseline and 2 years was 0.5 (IQR 0, 2.5). Among patients with an exacerbation of RA (n = 86), the median score for progression over 2 years was 1.0 (IQR 0, 4.5) (P <0.001), and in patients with a persistent remission (n = 93) it was 0 (IQR -0.5, 2.0) (P <0.001). Clinically relevant progression of damage was more frequent in patients with exacerbation (23%) than in those with persistent remission (7%) (P = 0.001). However, in 15% of patients with persistent remission, an erosion developed in a previously unaffected joint. In the logistic regression analysis, the area under the curve of the Disease Activity Score, a continuous measure, was related to the chance of radiologic progression, regardless of the absolute disease activity level. Results were similar when other definitions of remission were used. Although rare, clinically relevant progression of joint damage does occur in patients with RA in prolonged remission. This suggests the need for markers that predict progression during periods of low disease activity and for drugs that prevent damage that is independent of disease activit

    Objectives To investigate the effect of 2 years of add-on prednisolone 5 mg/day on body weight and composition in patients with active rheumatoid arthritis (RA) aged 65+ and the relation with disease activity.Methods The Glucocorticoid Low-dose Outcome in RheumatoId Arthritis trial, a pragmatic, placebo-controlled, double-blind, randomised controlled trial investigated the balance of benefit and harm of 2 years of prednisolone 5 mg/day added to standard care in 451 patients with active RA aged 65+. In the current study, 449 patients were included, and body weight and Disease Activity Score of 28 Joints were measured at baseline and after 3, 6, 12, 18 and 24 months. In 57 patients, body composition was assessed at baseline and after 2 years with dual-energy X-ray absorptiometry. Data were analysed with longitudinal mixed models.Results The mean (95% CI) change in body weight was 0.9 (0.3 to 1.6) kg in the prednisolone group and –0.4 (–1.1 to 0.2) kg in the placebo group (difference 1.3 (0.5–2.2), (p&lt;0.01)). The treatment effect was independent of disease activity suppression and comprised mostly increase in (appendicular) lean mass after 2 years. There was no significant increase in total fat mass, nor redistribution of fat mass from peripheral to central tissues.Conclusions Patients with active RA aged 65+ treated with prednisolone 5 mg/day for 2 years gained about 1 kg in weight, compared with minimal—non-significant—weight loss on placebo. Our data suggest that the small increase in weight is mostly lean mass, rather than increase or redistribution of fat mass traditionally associated with glucocorticoid treatment

    OBJECTIVE: Obesity is associated with elevated C reactive protein (CRP) levels. The Ankylosing Spondylitis Disease Activity Score (ASDAS) combines patient-reported outcomes (PROs) and CRP. We evaluated the effect of body mass index (BMI) on CRP and on ASDAS, and studied if ASDAS can be used in obese axial spondyloarthritis (axSpA) patients to assess disease activity. METHODS: Baseline data of patients with chronic back pain of short duration included in the SPondyloArthritis Caught Early (SPACE) cohort were used. Collected data included BMI and ASDAS. Patients were classified according to the ASAS axSpA classification criteria and BMI (overweight ≄25 and obese ≄30). Correlation and linear regression analyses were performed to assess the relation between BMI and ASDAS. Linear regression models were performed to assess if age or gender were effect modifiers in the relation between BMI and CRP, and between BMI and ASDAS. RESULTS: In total, 428 patients were analysed (n=168 axSpA; n=260 no-axSpA). The mean age was 31.1 years, 36.9% were male, 26.4% were overweight and 13.3% obese, median CRP was 3 mg/L and the mean ASDAS was 2.6. Gender was the only factor modifying the relationship between BMI and CRP as BMI had an influence on CRP only in females (ÎČ=0.35; p<0.001). Correlations between BMI and CRP or PROs were generally weak, and only significant for CRP in female patients. BMI was not related to ASDAS in axSpA patients. CONCLUSIONS: ASDAS is not affected by BMI in axSpA patients. Therefore, based on our data it is not necessary to take BMI in consideration when assessing disease activity using ASDAS in axSpA patients

    Objectives To compare outcomes of targeted treatment aimed at either low disease activity or remission in patients with early active rheumatoid arthritis (RA). Methods Five-year outcomes were compared in 133 patients with early active RA (1987), starting with methotrexate, sulfasalazine and tapered high dose of prednisone (arm 3 of the BehandelStrategieĂ«n (Treatment Strategies for Rheumatoid Arthritis) (BeSt) study), targeted at Disease Activity Score (DAS) ≀2.4 (low disease activity), and 175 patients with early RA, starting methotrexate and tapered high dose of prednisone, targeted at DAS <1.6 (selected from IMPROVED study who would have fulfilled inclusion criteria of the BeSt study). Association of treatment target with outcomes DAS <1.6, Boolean remission at year 1 and drug-free DAS remission (DFR) at year 5 were analysed by logistic regression analysis. Results At baseline, DAS <1.6 steered patients had a milder disease than DAS ≀2.4 steered patients (mean DAS 4.1±SD 0.7vs4.4±0.9, p=0.012) and less radiological damage. DAS decrease, functional ability and radiological damage progression over time were similar in both patient groups. DAS ≀2.4 was achieved in similar percentages in both patient groups, but more DAS <1.6 steered patients achieved DAS <1.6 and DFR. DAS <1.6 steered treatment was associated with achieving DAS <1.6 (OR 3.04 (95% CI 1.64 to 5.62)) and Boolean remission (3.03 (1.45 to 6.33)) at year 1 and DFR at year 5 (3.77 (1.51 to 9.43)). Conclusions In patients with early active RA who start with comparable disease-modifying antirheumatic drug+prednisone combination therapy, subsequent DAS <1.6 steered treatment is associated with similar clinical and radiological outcomes over time as DAS ≀2.4 steered treatment; however, in the DAS <1.6 steered group, more patients achieved remission and drug-free remission
