Construct validity and responsiveness of feasible composite disease activity measures for use in daily clinical practice in patients with psoriatic arthritis.

OBJECTIVE: There is a need for a widely accepted comprehensive disease activity measure for use in daily practice in patients with psoriatic arthritis (PsA). For this reason, the 3-item Visual Analogue Scale (3VAS) and 4-item Visual Analogue Scale (4VAS) were developed. This study aimed to test construct validity and responsiveness of the 3VAS and 4VAS in a population of patients with newly diagnosed PsA receiving usual care. METHODS: Components of the 3VAS (physician global, patient global, patient skin) and 4VAS (physician global, patient pain, patient joint, patient skin) were scored on 0-10 VAS scales. Agreement of low disease activity (LDA) state between 3VAS/4VAS and other composite measures was tested using Venn diagrams. Construct validity and responsiveness (3-month interval) were assessed using Spearman correlation coefficients and standardised response means (SRM) with effect sizes (ES), respectively, following hypothesis generation. Both 3VAS/4VAS were also compared with several patient-reported outcome measures. RESULTS: Data from 629 patients were used. Both 3VAS (ES=0.48, SRM 0.52) and 4VAS (ES=0.48, SRM=0.50) showed responsiveness similar to Disease Activity in PSoriatic Arthritis (DAPSA) and Disease Activity Score-28 (DAS28). Both measures had a strong correlation with DAPSA (r=0.80-0.87), Psoriatic Arthritis Disease Activity Score (PASDAS) (r=0.89) and Routine Assessment of Patient Index Data 3 (RAPID3) (r=0.84-0.92). 3VAS and 4VAS had the highest agreement with PASDAS in categorising patients to LDA at 12 months. CONCLUSION: This is the first study assessing the performance of the 3VAS and 4VAS in an observational cohort of patients with early PsA. Both measures have promising performance characteristics, showing strong correlations and good discrimination with existing composite measures. The 4VAS may be the preferred version with better face validity.

Frequency of joint inflammation is associated with local joint damage progression in rheumatoid arthritis despite long-term targeted treatment.

OBJECTIVES: To investigate whether in rheumatoid arthritis (RA) frequency of local joint inflammation is associated with radiographic joint damage progression in that joint. METHODS: Data from 473 patients with RA and available radiographs from the BeSt study were used. Patients were treated to target (Disease Activity Score of ≤2.4) for a median of 10 years. At each study visit every 3 months, joints were assessed for swelling and tenderness. Radiographs of hands and feet were made yearly. A generalised linear mixed model was used to assess the association between the percentage of study visits at which clinical inflammation was observed in a joint (cumulative inflammation) and radiographic joint damage in that same joint. Clinical inflammation was primarily defined as joint swelling (with or without joint tenderness). For secondary analyses, we also investigated joint tenderness without joint swelling. Damage was measured as the percentage of the maximum possible Sharp-Van der Heijde score in a particular joint. RESULTS: Cumulative local joint swelling was associated with local progression of radiographic damage in the same joint (ß=0.14, 95% CI 0.13 to 0.15). This association was also found in a subset of joints that were swollen at least once. Cumulative local joint tenderness without concurrent local joint swelling was less strongly associated with local radiographic joint damage progression (ß=0.04, 95% CI 0.03 to 0.05). CONCLUSIONS: In RA, long-term cumulative local joint inflammation is associated with joint damage progression in the same joint.

Impact of psoriasis remains important in psoriatic arthritis patients with low musculoskeletal disease activity.

OBJECTIVES: Achieving low disease activity (LDA) is important in patients with psoriatic arthritis. It is of value to know if health-related quality of life (HRQoL) of patients who reached musculoskeletal low disease activity can be further improved by additionally achieving remission of their psoriasis. So, the aim of this study was to assess HRQoL in patients with active psoriasis who reached disease activity in psoriatic arthritis (DAPSA) LDA after one year of follow-up. METHODS: Data were collected from the Dutch south west Psoriatic Arthritis cohort. Musculoskeletal disease activity was measured using DAPSA. Patients who reached DAPSA-LDA after one year were divided based on reaching psoriasis remission (Psoriasis Area and Severity Index [PASI] <1). HRQoL and work productivity were compared between both groups. RESULTS: After one year, 230 (44%) patients with active psoriasis at baseline reached DAPSA-LDA, of which 108 (47%) patients achieved psoriasis remission. The group of patients with active psoriasis (n=122, 53%) contained more men (p=0.023) and scored lower on the 12-item Psoriatic Arthritis Impact of Disease questionnaire (p=0.012). On the Skindex-17 psychosocial subscale, 31% experienced moderate to high impairment and on the symptoms subscale 28% experienced a lot of symptoms. Work productivity did not differ between both groups. CONCLUSIONS: The majority of patients with DAPSA-LDA and active psoriasis after one year has a good HRQoL. However, a proportion of these patients still experiences considerable skin burden. We recommend rheumatologists to continue assessing and treating psoriasis to reduce skin burden in PsA patients who achieved musculoskeletal low disease activity.

A Practical Guide for Assessment of Skin Burden in Patients With Psoriatic Arthritis.

OBJECTIVE: Rheumatologists play a pivotal role in the management of patients with psoriatic arthritis (PsA). Due to time constraints during clinic visits, the skin may not receive the attention needed for optimal patient outcome. Therefore, the aim of this study was to select a set of core questions that can help rheumatologists in daily rheumatology clinical practice to identify patients with PsA with a high skin burden. METHODS: Baseline data from patients included in the Dutch South West Psoriatic Arthritis (DEPAR) cohort were used. Questions were derived from the Skindex-17 and Dermatology Life Quality Index (DLQI) questionnaires. Underlying clusters of questions were identified with an exploratory principal component analysis (PCA) with varimax rotation, after which a 2-parameter logistic model was fitted per cluster. Questions were selected based on their discrimination and difficulty. Subsequently, 2 flowcharts were made with categories of skin burden severity. Clinical considerations were specified per category. RESULTS: In total, 413 patients were included. The PCA showed 2 underlying clusters: a psychosocial domain and a domain assessing physical symptoms. We selected these 2 domains. The psychosocial domain contains 3 questions and specifies 4 categories of skin burden severity. The physical symptoms domain contains 2 questions and categorizes patients in 1 out of 3 categories. CONCLUSION: We have selected a set with a maximum of 5 questions that rheumatologists can easily implement in their consultation to assess skin burden in patients with PsA. This practical guide makes the assessment of skin burden more accessible to rheumatologists and can aid in clinical decision making.

The burden of psoriasis in patients with early psoriatic arthritis.

OBJECTIVES: Psoriasis impacts health-related quality of life (HRQoL) in PsA patients. However, this is not adequately measured with a general HRQoL questionnaire. The aim of this study was to quantify the degree of psoriasis evolution in PsA patients over the first year of follow-up and to evaluate whether the impact of psoriasis on HRQoL can be adequately measured with a dermatology-specific HRQoL questionnaire. METHODS: Data were used from PsA patients in the Dutch south west Early Psoriatic Arthritis cohort. Psoriasis severity was measured with the Psoriasis Area and Severity Index (PASI). Dermatology-specific HRQoL was assessed with the Skindex-17 questionnaire. We used a Sankey diagram to illustrate the evolution of psoriasis severity during the first year of follow-up. To assess the association between psoriasis severity and the symptoms and psychosocial subscale of the Skindex-17, a linear regression analysis with hierarchical variable selection and zero-inflated negative binominal regression analysis were performed, respectively. RESULTS: We included 644 patients; 109 (17%) patients had no psoriasis (PASI = 0), 456 (71%) had mild psoriasis (PASI < 7), 56 (9%) had moderate psoriasis (PASI 7-12) and 23 (4%) had severe psoriasis (PASI > 12). Psoriasis severity did not fluctuate much during the first year. PASI was significantly associated with both subscales of the Skindex-17 at baseline and 12 months. CONCLUSION: Psoriasis severity in PsA patients is mostly mild but impacts HRQoL when measured using a dermatology-specific HRQoL questionnaire. For optimal management of PsA patients, we recommend rheumatologists acquire information on skin burden by using a dermatology-specific HRQoL questionnaire.

Joint inflammation tends to recur in the same joints during the rheumatoid arthritis disease course.

OBJECTIVES: We investigated whether local joint swelling recurs in the same joints over time in patients with rheumatoid arthritis (RA) who are treated to target. METHODS: Patients with newly diagnosed RA participating in the Behandel-Strategieën, "treatment strategies" (BeSt) study (n=508) were followed for median 10 years while receiving Disease Activity Score (DAS) ≤2.4 steered treatment. Every 3 months 68 joints were assessed for the presence of swelling. We evaluated whether baseline local joint swelling was predictive for swelling in the same joint during follow-up using a multilevel mixed-effect logistic regression model. Different strategies were used to account for missing data. A permutation test was performed to assess if joint swelling was better predicted by baseline swelling of the joint itself than by baseline swelling of randomly selected other joints. RESULTS: In 46% of the joints that were swollen at baseline, joint swelling later recurred at least once during follow-up. Joint swelling at baseline was statistically significantly associated with swelling in the same joint during follow-up (OR 2.37, 95% CI 2.30 to 2.43, p<0.001), and also specifically with recurrent swelling in the same joint (OR 1.73, 95% CI 1.37 to 1.59, p<0.001). Local joint swelling was better predicted by baseline swelling of that particular joint than by baseline swelling of other joints (p<0.001). CONCLUSION: Joint swelling tends to recur locally in the joints swollen at RA onset. This suggests that local factors influence the manifestation of joint inflammation over time.

Earlier is better when treating rheumatoid arthritis: but can we detect a window of opportunity?

OBJECTIVES: The window of opportunity (WOO) hypothesis suggests a limited time frame to stop rheumatoid arthritis (RA). We hypothesised that a WOO could either be represented by a hyperbolic ('curved') decline in the chance to achieve the outcome sustained drug-free remission (sDFR) over time, after which achieving sDFR is not possible anymore, or by a more gradual linear decline approaching zero chance to achieve sDFR. METHODS: Patients with RA (symptom duration <2 years) were included from two randomised trials: BehandelStrategieën (BeSt), n=508 and Induction therapy with Methotrexate and Prednisone in Rheumatoid Or Very Early arthritic Disease (IMPROVED), n=479. Cox-regression was performed to assess the shape of the association between symptom duration and sDFR (Disease Activity Score<1.6, no disease-modifying anti-rheumatic drugs for ≥1 year) for patients starting slow-acting monotherapy (IMPROVED, BeSt) or fast-acting combination therapy (BeSt). Likelihood ratio tests were used to compare the fit of linear and non-linear models in both databases separately. Predictions from the best fitting models were used to assess whether the absolute risk to achieve sDFR approaches zero with increasing symptom duration. RESULTS: In BeSt and IMPROVED, 54/226 and 110/421 patients achieved sDFR with fast-acting treatment, and 53/243 (BeSt) with slow-acting treatment. Non-linear models did not fit better than linear models (fast-acting treatment BeSt p=0.743, IMPROVED p=0.337; slow-acting treatment BeSt p=0.609). After slow-acting monotherapy, linear models declined steeper. None of the models approached zero chance to achieve sDFR over time. CONCLUSIONS: The chance to achieve sDFR decreased gradually over time, and decreased fastest in patients starting slow-acting monotherapy. In both treatment groups, we found no evidence for a WOO within 2 years symptom duration.

Gradual tapering TNF inhibitors versus conventional synthetic DMARDs after achieving controlled disease in patients with rheumatoid arthritis: first-year results of the randomised controlled TARA study.

OBJECTIVES: The aim of this study is to evaluate the effectiveness of two tapering strategies after achieving controlled disease in patients with rheumatoid arthritis (RA), during 1 year of follow-up. METHODS: In this multicentre single-blinded (research nurses) randomised controlled trial, patients with RA were included who achieved controlled disease, defined as a Disease Activity Score (DAS) ≤ 2.4 and a Swollen Joint Count (SJC) ≤ 1, treated with both a conventional synthetic disease-modifying antirheumatic drugs (csDMARD) and a TNF inhibitor. Eligible patients were randomised into gradual tapering csDMARDs or TNF inhibitors. Medication was tapered if the RA was still under control, by cutting the dosage into half, a quarter and thereafter it was stopped. Primary outcome was proportion of patients with a disease flare, defined as DAS > 2.4 and/or SJC > 1. Secondary outcomes were DAS, European Quality of Life-5 Dimensions (EQ5D) and functional ability (Health Assessment Questionnaire Disability Index [HAQ-DI]) after 1 year and over time. RESULTS: A total of 189 patients were randomly assigned to tapering csDMARDs (n = 94) or tapering anti-TNF (n = 95). The cumulative flare rates in the csDMARD and anti-TNF tapering group were, respectively, 33 % (95% CI,24% to 43 %) and 43 % (95% CI, 33% to 53 % (p = 0.17). Mean DAS, HAQ-DI and EQ-5D did not differ between tapering groups after 1 year and over time. CONCLUSION: Up to 9 months, flare rates of tapering csDMARDs or TNF inhibitors were similar. After 1 year, a non-significant difference was found of 10 % favouring csDMARD tapering. Tapering TNF inhibitors was, therefore, not superior to tapering csDMARDs. From a societal perspective, it would be sensible to taper the TNF inhibitor first, because of possible cost reductions and less long-term side effects. TRIAL REGISTRATION NUMBER: NTR2754.

Impact of Stopping Tumor Necrosis Factor Inhibitors on Rheumatoid Arthritis Patients' Burden of Disease.

OBJECTIVE: To determine the impact of stopping tumor necrosis factor inhibitor (TNFi) treatment on patient-reported outcomes (PROs) of physical and mental health status, health utility, pain, disability, and fatigue in patients with established rheumatoid arthritis (RA). METHODS: In the pragmatic, 12-month POET trial, 817 RA patients with ≥6 months of remission or stable low disease activity were randomized 2:1 to stopping or continuing TNFi. In case of flare, TNFi was restarted at the discretion of the rheumatologist. PROs were assessed every 3 months. RESULTS: TNFi was restarted within 12 months in 252 of 531 patients (47.5%) in the stop group. At 3 months, mean PRO scores were significantly worse in the stop group, and a larger proportion of patients experienced a minimum clinically important difference (MCID) on all PROs. Effect sizes (ES) were strongest for health utility (ES -0.24) and pain (ES -0.30). Mean scores improved again after this point, but disability scores remained significantly different at 12 months. After 12 months, the relative risk of experiencing an MCID ranged from 1.16 for mental health status to 1.58 for fatigue. Mean PRO scores for patients restarting TNFi within 6 months were no longer significantly different from those that did not restart TNFi at 12 months. CONCLUSION: Stopping TNFi had a significant negative short-term impact on a broad range of PROs. Long-term negative consequences appeared to be limited, and outcomes in patients needing to restart TNFi within the first 6 months tended to be restored at 12 months.

Limited value for ultrasonography in predicting flare in rheumatoid arthritis patients with low disease activity stopping TNF inhibitors.

Objective: Ultrasonography (US) can be used for treatment decisions in RA patients. This study investigated the added value of US to clinical variables in predicting flare in RA patients with longstanding low disease activity when stopping TNF inhibitors (TNFi). Methods: Cox models with and without using US added to clinical variables were developed in the Potential Optimization of Expediency of TNFi-UltraSonography study. RA patients (n = 259), using >1 year TNFi and csDMARD with DAS28 < 3.2 for 6 months prior to inclusion, were followed for 52 weeks after stopping TNFi. The added value of US was assessed in two ways: first, by the extent to which individual predictions for flare at 52 weeks with and without US differed; and second, by comparing how US information improved the prediction to classify patients at 52 weeks in the low risk (<33% flare), intermediate risk (33-50%) and high risk (50-100%) groups. Results: Although US was predictive of flare at group level (multivariate hazard ratio = 1.7; 95% CI: 1.1, 2.5), individual predictions for flare at 52 weeks with and without US differed little (median difference 3.7%; interquartile range: -7.8 to 6.5%). With US, 15.9% of patients were designated low risk; without US, 14.6%. In fact, 12.0% of patients were US-classified as low risk with/without knowing US. Conclusion: In RA patients with longstanding low disease activity, at time of stopping TNFi, US is a predictor for flare at group level, but at the patient level, US has limited added value when common clinical parameters are used already, though the predictive value of clinical predictors is modest as well.

Long-Term Outcomes of Patients With Recent-Onset Rheumatoid Arthritis After 10 Years of Tight Controlled Treatment: A Randomized Trial.

BACKGROUND: Treat-to-target therapy is effective for patients with rheumatoid arthritis (RA), but long-term results of continued targeted treatment are lacking. OBJECTIVE: To evaluate long-term outcomes in patients with early RA after 10 years of targeted treatment in 4 treatment strategies. DESIGN: Randomized trial. (Nederlands Trial Register: NTR262 and NTR265). SETTING: The Netherlands. PATIENTS: 508 patients with early active RA. INTERVENTION: Sequential monotherapy (strategy 1), step-up combination therapy (strategy 2), or initial combination therapy with prednisone (strategy 3) or with infliximab (strategy 4), all followed by targeted treatment aiming at low disease activity. MEASUREMENTS: Functional ability (Health Assessment Questionnaire [HAQ] score) and radiographic progression (Sharp-van der Heijde score) were primary end points. Survival in the study population was compared with the general population using the standardized mortality ratio. RESULTS: 195 of 508 of patients (38%) dropped out of the study (28% in strategy 4 vs. 40% to 45% in strategies 1 to 3, respectively). At year 10, mean HAQ score (SD) was 0.57 (0.56); 53% and 14% of patients were in remission and drug-free remission, respectively, without differences among the strategies. Over 10 years, mean HAQ scores were 0.69, 0.72, 0.64, and 0.58 in strategies 1 to 4, respectively (differences not clinically relevant). Radiographic damage was limited for all strategies, with mean Sharp-van der Heijde estimates during follow-up of 11, 8, 8, and 6 in strategies 1 to 4, respectively (P = 0.15). Standardized mortality ratio was 1.16 (95% CI, 0.92 to 1.46) based on 72 observed and 62 expected deaths, with similar survival among the 4 strategies (P = 0.81). LIMITATION: Dropout rate varied by strategy. CONCLUSION: In patients with early RA, initial (temporary) combination therapy results in faster clinical improvement and targeted treatment determines long-term outcomes. Drug-free remission, with prevention of functional deterioration and clinically relevant radiographic damage, and normalized survival are realistic outcomes.

Predictive factors of radiological progression after 2†years of remission-steered treatment in early arthritis patients: a post hoc analysis of the IMPROVED study.

OBJECTIVES: To identify predictive factors of radiological progression in early arthritis patients treated by remission-steered treatment. METHODS: In the IMPROVED study, 610 patients with early rheumatoid arthritis (RA) or undifferentiated arthritis (UA) were treated with methotrexate (MTX) and a tapered high dose of prednisone. Patients in early remission (disease activity score (DAS) <1.6 after 4 months) tapered prednisone to zero. Patients not in early remission were randomised to arm 1: MTX plus hydroxychloroquine, sulfasalazine and prednisone, or to arm 2: MTX plus adalimumab. Predictors of radiological progression (≥0.5 Sharp/van der Heijde score; SHS) after 2 years were assessed using logistic regression analysis. RESULTS: Median (IQR) SHS progression in 488 patients was 0 (0-0) point, without differences between RA or UA patients or between treatment arms. In only 50/488 patients, the SHS progression was ≥0.5: 33 (66%) were in the early DAS remission group, 9 (18%) in arm 1, 5 (10%) in arm 2, 3 (6%) in the outside of protocol group. Age (OR (95% CI): 1.03 (1.00 to 1.06)) and the combined presence of anticarbamylated protein antibodies (anti-CarP) and anticitrullinated protein antibodies (ACPA) (2.54 (1.16 to 5.58)) were independent predictors for SHS progression. Symptom duration <12 weeks showed a trend. CONCLUSIONS: After 2 years of remission steered treatment in early arthritis patients, there was limited SHS progression in only a small group of patients. Numerically, patients who had achieved early DAS remission had more SHS progression than other patients. Positivity for both anti-CarP and ACPA and age were independently associated with SHS progression. TRIAL REGISTRATION NUMBERS: ISRCTN Register number 11916566 and EudraCT number 2006 06186-16.

Rheumatology education in Europe: results of a survey of young rheumatologists.

OBJECTIVES: To evaluate the level of education and participation in an internship abroad and to European league against rheumatism (EULAR) on line course of young rheumatologists. To define new tools for learning. METHODS: Questionnaires were administered to 170 trainees and young specialists in 2008-2009 during official EULAR meetings or using the mailing list of European young rheumatologists in training. The questions with related visual analogical scale (VAS score 0-10) for satisfaction encompassed the following issues: languages, computer, daily hours employed, different items of medical culture, internship abroad, EULAR on-line course and bursaries. VAS>6 was considered a good level of satisfaction. RESULTS: 170 young rheumatologists (113 trainees and 57 specialists, 33±4.2 years old) from 32 EULAR countries did not approve their own national training (42.3%), believed in an European common education system (90.5%), had a good knowledge of English (85.7%) and computer (90.5%) and spent the majority of time in clinical practice (57.5%) in comparison with study and research. The young rheumatologists had higher competence in drug management (93.5%) than in clinical assessment and knowledge of imaging and anatomy, and mostly suggested new ways of communication (61.4% on-line courses and 66.1% DVD) to improve their education. 38% made stage abroad and participated to EULAR on-line course, with high satisfaction, but only half of them were granted by bursaries. CONCLUSIONS: Young rheumatologists are low confident in their own education and believe that visits to other training centers and new ways of learning (on line and DVD) might improve their competence.

Accelerated hand bone mineral density loss is associated with progressive joint damage in hands and feet in recent-onset rheumatoid arthritis.

INTRODUCTION: To investigate whether accelerated hand bone mineral density (BMD) loss is associated with progressive joint damage in hands and feet in the first year of rheumatoid arthritis (RA) and whether it is an independent predictor of subsequent progressive total joint damage after 4 years. METHODS: In 256 recent-onset RA patients, baseline and 1-year hand BMD was measured in metacarpals 2-4 by digital X-ray radiogrammetry. Joint damage in hands and feet were scored in random order according to the Sharp-van der Heijde method at baseline and yearly up to 4 years. RESULTS: 68% of the patients had accelerated hand BMD loss (>-0.003 g/cm2) in the first year of RA. Hand BMD loss was associated with progressive joint damage after 1 year both in hands and feet with odds ratios (OR) (95% confidence intervals [CI]) of 5.3 (1.3-20.9) and 3.1 (1.0-9.7). In univariate analysis, hand BMD loss in the first year was a predictor of subsequent progressive total joint damage after 4 years with an OR (95% CI) of 3.1 (1.3-7.6). Multivariate analysis showed that only progressive joint damage in the first year and anti-citrullinated protein antibody positivity were independent predictors of long-term progressive joint damage. CONCLUSIONS: In the first year of RA, accelerated hand BMD loss is associated with progressive joint damage in both hands and feet. Hand BMD loss in the first year of recent-onset RA predicts subsequent progressive total joint damage, however not independent of progressive joint damage in the first year.

Blood pressure changes in patients with recent-onset rheumatoid arthritis treated with four different treatment strategies: a post hoc analysis from the BeSt trial.

OBJECTIVE: To evaluate the effect of disease activity and antirheumatic treatment on blood pressure (BP) in patients with recent-onset rheumatoid arthritis (RA). METHODS: 508 patients with RA were randomised to receive (1) sequential monotherapy, (2) step-up combination therapy, (3) initial combination with prednisone or (4) with infliximab. Systolic and diastolic BP (SBP, DBP), disease activity score (DAS) and body mass index (BMI) were evaluated every 3 months. A linear mixed model was used to model SBP and DBP in each treatment group during year 1, adjusting for baseline BP, changes in BMI, DAS and cardiovascular medication. RESULTS: In all groups, mean SBP and DBP were lower for patients with DAS < or =2.4 than for patients with DAS >2.4. In addition, patients initially treated with infliximab (group 4) had a larger decrease in SBP and DBP over time than patients in groups 1-3. The decrease in BP was also observed in patients treated with infliximab after failure on conventional disease-modifying antirheumatic drugs in groups 1-3. The decrease in BP associated with treatment with infliximab occurred irrespective of the DAS response. CONCLUSION: A lower DAS is associated with lower BP. An additional decrease in BP was observed in patients treated with infliximab. Further research is needed to confirm the effect of infliximab on BP.

Rheumatoid arthritis: can we achieve true drug-free remission in patients with RA?

Since the introduction of new biologic agents and intensive treatment strategies that aim to tightly control disease activity, clinical remission has become a realistic target in patients with rheumatoid arthritis. Once patients are in continuous remission, however, is it realistic to consider withdrawing DMARD therapy?

Cost-utility analysis of treatment strategies in patients with recent-onset rheumatoid arthritis.

OBJECTIVE: To evaluate societal costs and quality-adjusted life years (QALYs) of treatment strategies for patients with recent-onset active rheumatoid arthritis (RA). METHODS: Patients (n = 508) were randomly allocated to 1 of 4 treatment strategy groups: sequential monotherapy, step-up combination therapy, initial combination therapy with prednisone, or initial combination therapy with infliximab. For 2 years, patients reported cost and utility measures. RESULTS: Average QALYs (ideally 2.00) for groups 1-4 were 1.29, 1.31, 1.32, and 1.41, respectively, for the British EuroQol (P

Patient preferences for treatment: report from a randomised comparison of treatment strategies in early rheumatoid arthritis (BeSt trial).

OBJECTIVE: To determine treatment preferences among patients with recent onset rheumatoid arthritis participating in a randomised controlled trial comparing four therapeutic strategies. METHODS: A questionnaire was sent to all 508 participants of the BeSt trial, treated for an average of 2.2 years with either sequential monotherapy (group 1), step-up combination therapy (group 2), initial combination therapy with tapered high-dose prednisone (group 3), or initial combination therapy with infliximab (group 4). Treatment adjustments were made every 3 months to achieve low disease activity (DAS < or =2.4). The questionnaire explored patients' preferences or dislikes for the initial therapy. RESULTS: In total, 440 patients (87%) completed the questionnaire. Despite virtually equal study outcomes at 2 years, more patients in group 4 reported much or very much improvement of general health: 50%, 56%, 46% and 74% in groups 1-4, respectively (overall, P<0.001). Almost half of the patients expressed no preference or aversion for a particular treatment group, 33% had hoped for assignment to group 4 and 38% had hoped against assignment to group 3. This negative perception was much less prominent in patients actually in group 3. Nevertheless, 50% of patients in group 3 disliked having to take prednisone, while only 8% in group 4 disliked going to the hospital for intravenous treatment. CONCLUSIONS: Within the limitations of our retrospective study, patients clearly preferred initial combination therapy with infliximab and disliked taking prednisone. After actual exposure, this preference remained, but the perception of prednisone improved. Patient perceptions need to be addressed when administering treatment.

Comparison of treatment strategies in early rheumatoid arthritis: a randomized trial.

BACKGROUND: In patients with early rheumatoid arthritis, initial combination therapies provide earlier clinical improvement and less progression of joint damage after 1 year compared with initial monotherapies (as demonstrated in the BeSt study). OBJECTIVE: To evaluate whether the initial clinical and radiographic efficacy of combination therapies could be maintained during the second year of follow-up in patients with early rheumatoid arthritis. DESIGN: Randomized, controlled clinical trial with blinded assessors. SETTING: 18 peripheral and 2 university medical centers in the Netherlands. PATIENTS: 508 patients with early active rheumatoid arthritis. INTERVENTION: Sequential monotherapy (group 1), step-up combination therapy (group 2), initial combination therapy with tapered high-dose prednisone (group 3), or initial combination therapy with infliximab (group 4). Trimonthly treatment adjustments were made to achieve low disease activity. MEASUREMENTS: Primary end points were functional ability (Health Assessment Questionnaire) and Sharp-van der Heijde score for radiographic joint damage. RESULTS: Groups 3 and 4 had more rapid clinical improvement during the first year; all groups improved further to a mean functional ability score of 0.6 (overall, P = 0.257) and 42% were in remission (overall, P = 0.690) during the second year. Progression of joint damage remained better suppressed in groups 3 and 4 (median scores of 2.0, 2.0, 1.0, and 1.0 in groups 1, 2, 3, and 4, respectively [P = 0.004]). After 2 years, 33%, 31%, 36%, and 53% of patients in groups 1 through 4, respectively, were receiving single-drug therapy for initial treatment. There were no significant differences in toxicity. LIMITATIONS: Patients and physicians were aware of the allocated group, and the assessors were blinded. CONCLUSIONS: Currently available antirheumatic drugs can be highly effective in patients with early rheumatoid arthritis in a setting of tight disease control. Initial combination therapies seem to provide earlier clinical improvement and less progression of joint damage, but all treatment strategies eventually showed similar clinical improvements. In addition, combination therapy can be withdrawn successfully and less treatment adjustments are needed than with initial monotherapies.
