RESUMO
OBJECTIVE: The randomised placebo-controlled GLORIA (Glucocorticoid LOw-dose in RheumatoId Arthritis) trial evaluated the benefits and harms of prednisolone 5 mg/day added to standard care for 2 years in patients aged 65+ years with rheumatoid arthritis (RA). Here, we studied disease activity, flares and possible adrenal insufficiency after blinded withdrawal of study medication. METHODS: Per protocol, patients successfully completing the 2-year trial period linearly tapered and stopped blinded study medication in 3 months. We compared changes in disease activity after taper between treatment groups (one-sided testing). Secondary outcomes (two-sided tests) comprised disease flares (DAS28 (Disease Activity Score 28 joints) increase >0.6, open-label glucocorticoids or disease-modifying antirheumatic drug (DMARD) increase/switch after week 4 of tapering) and symptoms/signs of adrenal insufficiency. In a subset of patients from 3 Dutch centres, cortisol and ACTH were measured in spot serum samples after tapering. RESULTS: 191 patients were eligible; 36 met treatment-related flare criteria and were only included in the flare analysis. Mean (SD) DAS28 change at follow-up: 0.2 (1.0) in the prednisolone group (n=76) vs 0.0 (1.2) in placebo (n=79). Adjusted for baseline, the between-group difference in DAS28 increase was 0.16 (95% confidence limit -0.06, p=0.12). Flares occurred in 45% of prednisolone patients compared with 33% in placebo, relative risk (RR) 1.37 (95% CI 0.95 to 1.98; p=0.12). We found no evidence for adrenal insufficiency. CONCLUSIONS: Tapering prednisolone moderately increases disease activity to the levels of the placebo group (mean still at low disease activity levels) and numerically increases the risk of flare without evidence for adrenal insufficiency. This suggests that withdrawal of low-dose prednisolone is feasible and safe after 2 years of administration.

OBJECTIVES: Self-monitoring and patient-initiated care (PIC) leads to fewer outpatient clinic visits in patients with established RA with low disease activity (LDA) while healthcare outcomes are similar. This study assesses the cost-effectiveness of PIC with self-monitoring. METHODS: A 12-month randomized controlled trial was performed with 49 patients in the PIC with self-monitoring group (app-group) and 53 in usual care. The usual care group continued with preplanned visits. The app group had one planned follow-up visit after 12 months and monitored their RA disease activity in a smartphone app. Both groups could make additional appointments at liberty. We included adult RA patients with a disease duration of over 2 years, a disease activity score 28 (DAS28) below 3.2 that were stable on medication for at least 6 months. The effect measure, the DAS28, was measured at 12 months and healthcare resource usage and productivity losses were measured at 3, 6, 9 and 12 months. RESULTS: There was no significant difference in mean change of DAS28 (-0.04 mean difference, 95% CI: -0.39, 0.30), nor a statistically significant difference in total costs (mean difference 514, 95% CI:-266, 3690) in the app group compared with the usual care group. The probability that the app was cost-effective was 0.37 and 0.57 at a willingness-to-pay threshold of 0 and 50 000 /point improvement DAS28, respectively. CONCLUSION: Although rheumatic care costs were significantly lower in the app group, total costs and effects of PIC with self-monitoring were not different from usual care in RA patients with LDA.

OBJECTIVE: The aim of this study was to investigate the effect of treat-to-target combination therapy with intensification at 13 weeks in early RA. METHODS: Early RA patients were classified as being at high or low risk of worsening RA based on disease activity and prognostic factors. High-risk patients received COBRA-light (prednisolone 30 mg/day tapered to 7.5 mg/day, MTX increasing to 25 mg/week), and low-risk patients received MTX monotherapy increasing to 25 mg/week. The primary outcome (target) was DAS44 < 1.6 or EULAR good response at 26 weeks. At 13 weeks, non-responders were randomized to (open-label) intensification [high-risk patients: prednisolone 60 mg/day tapered to 7.5 mg/day, addition of SSZ (2 g/day) and HCQ (400 mg/day); low-risk patients: prednisolone 30 mg/day tapered to 7.5 mg/day] or continuation. RESULTS: In the high-risk group (n = 150), 110 patients (73%) reached the target at 13 weeks, and 9 dropped out. Non-responders were randomized to intensification (n = 15) or continuation (n = 16), and after 26 weeks, 12 (80%) vs 7 (44%) of these, respectively, reached the target [difference: 36%, (95% CI 2%, 71%); P = 0.04]. In the low-risk group (n = 40), 17 (43%) reached the target. Non-responders were randomized to intensification (n = 8) or continuation (n = 7); 4 vs 3, respectively, reached the target.Adverse event rates were higher in the high-risk group, and higher in the intensification subgroup of that group. Serious adverse events were rare. Protocol violations were frequent and mostly led to mitigation of actual treatment intensification. CONCLUSION: Initial combination therapy was very successful in high-risk RA, and early intensification was beneficial in patients not reaching the strict target. The low-risk group was too small for drawing conclusions. In routine practice, adherence to early intensification based on strict targets is difficult.

Routine collection of electronic patient-reported outcomes (ePROs) can improve clinical care. However, a low response rate may counteract the benefits. To optimize adoption, the aim of this study was to investigate which patient factors and/or timing of the invitation predicted response to ePROs sent prior to consultations in patients with rheumatoid arthritis. We performed a retrospective database study with clinical data collected as part of usual care from the electronic medical records at Reade Amsterdam. The dataset comprised the email invitations to complete the ePRO sent prior to consultation. Multiple patient factors and factors defining the timing of the invitation were investigated if they predicted response to the ePRO through a multivariable logistic generalized estimating equation analysis. In total, 17.070 ePRO invitations were sent to 3194 patients (mean age 60 (SD 14), 74% female), of which 40% was completed. Patients between 55 and 73 years (OR 1.39, 95%CI 1.09-1.77) and with higher social economic status (SES) (OR 1.51, 95%CI 1.22-1.88) had significantly higher odds for completing the ePRO, while patients living in an urban area had lower odds (OR 0.69, 95% CI 0.62-0.76). In year 4 after implementation, the OR was increased to 3.69 (95% CI 2.91-4.90). The implementation of ePROs in daily clinical practice needs improvement since 40% of the ePROs sent prior to consultations were completed. Patients that had higher odds to report the next ePRO were between the age of 55-73, had a higher socio-economic status, and were residents in a rural area. The adoption of reporting the PRO increased over time, but the timing of the prompt did not predict response. Additional research is needed to understand ePRO completion, especially for patients with lower socio-economic status.

Telemonitoring disease activity with electronic patient-reported outcomes (ePROs) may reduce the workload of rheumatic care by decreasing outpatient clinic visits. However, low adherence to reporting ePROs is frequently observed. Our objective was to identify facilitators and barriers to weekly monitoring of disease activity with ePROs. Patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), or ankylosing spondylitis (AS) who recently participated in one of the two telemonitoring studies with ePROs completed in a smartphone app, were invited to participate in focus group discussions (FGD). Thematic analysis was used to identify themes that play a role in the decision to continue or stop reporting weekly ePROs. A total of 22 patients participated in three FGDs. Five themes were identified that were of importance to adhere to telemonitoring: (1) questionnaire frequency, (2) discussing results of completed ePROs, (3) physical consultations, (4) patient insight into disease activity and (5) user experience of the app. All themes contained both barrier and facilitator elements. The results suggest that to improve adherence to telemonitoring of disease activity with ePROs, the perceived benefits of completing ePROs should be maximized. This can be done by providing patients the ability to skip (unneeded) physical consultations in case of low disease activity, and training clinicians to always discuss the completed ePROs. In addition, it is essential to reduce the effort to report ePROs, by tailoring the frequency of ePROs based on the patients' disease activity or preference, aiming for optimal app functionality as well as by sending notifications when new ePROs are available.

OBJECTIVES: This systematic review assessed which variables are associated with or are predictors for work participation outcomes in patients with systematic lupus erythematosus (SLE). METHODS: A literature search using MEDLINE, The Cochrane Library, Embase and CINAHL was conducted to identify all studies published from inception (1947) to June 2021 on factors related to and/or predicting employment status, absenteeism and/or presenteeism in SLE patients aged ≥18 years. The quality of included articles was assessed using the QUIPS tool. Narrative summaries were used to present the data. RESULTS: Fifteen studies (nine on associations, four on predictions, and two assessing both) were included, encompassing data of 3800 employed patients. Younger age, Caucasian ethnicity, higher educational level, lower disease activity score, shorter disease duration, absence of specific disease manifestations, higher levels of physical functioning and less physical job demands and higher levels of psychological/cognitive functioning were associated with or predicted favorable work outcomes. Older age, non-Caucasian ethnicity, female gender, never being married, poverty, lower educational level, higher disease activity score, longer disease duration, specific disease manifestations, lower levels of physical functioning, more physical job demands and low job control, less job tenure and lower levels of cognitive functioning were associated with or predicted an unfavorable work outcome. Limitations of the evidence were the quality of the studies and the use of heterogeneous outcome measures, applied statistical methods and instruments used to assess work participation. CONCLUSION: We recommend applying the EULAR points to consider for designing, analysing and reporting on work participation in inflammatory arthritis also to SLE studies on work participation, to enhance the quality and comparability between studies and to better understand the impact of SLE on work participation.

STUDY OBJECTIVE: To compare the prognostic accuracy of clinical judgment for frailty in older patients at the emergency department with a validated screening instrument and patient-perceived frailty. METHODS: A prospective cohort study in patients 70 years of age and older in 2 Dutch EDs with a follow-up of 3 months. A dichotomous question was asked to the physician and patient: "Do you consider the patient / yourself to be frail?" The Identification of Seniors At Risk-Hospitalized Patients (ISAR-HP) was used as a validated screening instrument. The primary composite outcome consisted of either functional decline, institutionalization, or mortality. RESULTS: A total of 736 patients were included. The physician identified 59% as frail, compared with 49% by ISAR-HP and 43% by patients themselves. The level of agreement was fair (Fleiss Kappa, 0.31). After 3 months, 31% of the patients experienced at least 1 adverse health outcome. The sensitivity was 79% for the physician, 72% for ISAR-HP, 61% for the patient, and 48% for all 3 combined. The specificity was 50% for the physician, 63% for ISAR-HP, 66% for the patient, and 85% for all 3 positive. The highest positive likelihood ratio was 3.03 (physician, ISAR-HP, patient combined), and the lowest negative likelihood ratio was 0.42 (physician). The areas under the receiver operating curves were all poor: 0.68 at best for ISAR-HP. CONCLUSION: Clinical judgment for frailty showed fair agreement with a validated screening instrument and patient-perceived frailty. All 3 instruments have poor prognostic accuracy, which does not improve when combined. These findings illustrate the limited prognostic value of clinical judgment as a frailty screener in older patients at the ED.

BACKGROUND: Patients with rheumatoid arthritis require frequent consultations to monitor disease activity and intensify medication when treatment targets are not met. However, because most patients are in remission during follow-up, it should be possible to reduce the number of consultations for them. Electronic patient-reported outcomes (ePROs) could be used to identify patients who meet their treatment goal and who could therefore be eligible to skip their visit. OBJECTIVE: The aim of this study was to assess the probability that patients with low disease activity scores on their ePROs do not need a disease-modifying antirheumatic drug (DMARD) or steroid intensification in the first 2 weeks after completion of the ePROs. METHODS: This medical-records review study compared results of ePROs answered during routine care with DMARD or steroid intensifications collected from anonymized electronic medical record at Reade. The primary outcome was the positive predictive value (PPV) of having a low disease activity score on an ePRO for not receiving a DMARD or steroid intensifications within 2 weeks. The 3 studied ePROs (and respective low disease activity outcome) were the Routine Assessment of Patient Index Data 3 (RAPID3) (score <2), Patient Acceptable Symptom State (PASS) (yes), and the flare question (no). The secondary aim of the study was to assess which combination of ePROs resulted in the best PPV for DMARD or steroid intensifications. RESULTS: Of the 400 randomly selected records, ultimately 321 were included (302 unique patients). The PPV of a RAPID3 <2, being in PASS, and a negative answer on the flare question were, respectively, 99%, 95%, and 83% to not receive a DMARD or steroid intensification within 2 weeks. The combination of a RAPID3 <2 and a negative flare question resulted in a PPV of 100%; this combination was present in 29% (93/321) of the total study population. CONCLUSION: The RAPID3, PASS, and flare question have a high diagnostic accuracy to identify individuals who will not receive a DMARD or steroid intensification in the following 2 weeks. The combination of the RAPID3 and flare question yielded the best combination of diagnostic accuracy and highest percentage of patients who could be eligible to skip a visit. These results suggest that accurate identification of patients who meet their treatment goal with ePROs is possible.

BACKGROUND: Clinical studies with work participation (WP) as an outcome domain pose particular methodological challenges that hamper interpretation, comparison between studies and meta-analyses. OBJECTIVES: To develop Points to Consider (PtC) for design, analysis and reporting of studies of patients with inflammatory arthritis that include WP as a primary or secondary outcome domain. METHODS: The EULAR Standardised Operating Procedures were followed. A multidisciplinary taskforce with 22 experts including patients with rheumatic diseases, from 10 EULAR countries and Canada, identified methodologic areas of concern. Two systematic literature reviews (SLR) appraised the methodology across these areas. In parallel, two surveys among professional societies and experts outside the taskforce sought for additional methodological areas or existing conducting/reporting recommendations. The taskforce formulated the PtC after presentation of the SLRs and survey results, and discussion. Consensus was obtained through informal voting, with levels of agreement obtained anonymously. RESULTS: Two overarching principles and nine PtC were formulated. The taskforce recommends to align the work-related study objective to the design, duration, and outcome domains/measurement instruments of the study (PtC: 1-3); to identify contextual factors upfront and account for them in analyses (PtC: 4); to account for interdependence of different work outcome domains and for changes in work status over time (PtC: 5-7); to present results as means as well as proportions of patients reaching predefined meaningful categories (PtC: 8) and to explicitly report volumes of productivity loss when costs are an outcome (PtC:9). CONCLUSION: Adherence to these EULAR PtC will improve the methodological quality of studies evaluating WP.

OBJECTIVES: An efficient pharmacological response to MTX treatment in RA patients relies on the retention and accumulation of intracellular MTX-polyglutamates catalysed by the enzyme folylpolyglutamate synthetase (FPGS). We recently identified a partial retention of FPGS intron 8 (8PR) as a prominent splice variant conferring FPGS dysfunction and decreased MTX polyglutamylation in acute lymphoblastic leukaemia. Here, we explored the association between FPGS 8PR levels and lack of MTX responsiveness in RA patients. METHODS: Thirty-six patients undergoing MTX treatment were enrolled from the Combinatie behandeling Reumatoide Artritis (COBRA)-light trial. RNA was isolated from blood samples at baseline, 13 weeks and 26 weeks of therapy, from patients in either COBRA-light (n = 21) or COBRA (n = 15) treatment arms. RT-qPCR analysis was used to assess RNA levels of FPGS 8PR over wild-type FPGS (8WT). RESULTS: In the COBRA-light treatment arm, higher baseline ratios of 8PR/8WT were significantly associated with higher 44-joint disease activity score (DAS44) at 13 and 26 weeks. Higher baseline ratios of 8PR/8WT also trended towards not obtaining low disease activity (DAS <1.6) and becoming a EULAR non-responder at 13 and 26 weeks. In the COBRA-treatment arm, a significant association was observed between high baseline 8PR/8WT ratios and higher DAS44 score at 26 weeks. Higher 8PR/8WT ratios were associated with non-response at week 26 based on both low disease activity and EULAR criteria. CONCLUSION: This study is the first to associate alterations in FPGS pre-mRNA splicing levels with reduced responsiveness to MTX treatment in RA patients. TRIAL REGISTRATION: ISRCTN55552928.

STUDY OBJECTIVE: Older adults presenting to the emergency department (ED) are at high risk of adverse health outcomes. This study aimed to evaluate the accuracy of 4 frequently used screening instruments for the prediction of adverse health outcomes among older adults in the ED. METHODS: This was a prospective cohort study in patients ≥70 years of age presenting to the ED in 2 hospitals in the Netherlands. Screening instruments included the acutely presenting older patient screening program (APOP) (providing 2 risk scores-functional decline [APOP1] and mortality [APOP2]), the International Resident Assessment Instrument Emergendy Department screener (InterRAI ED), the Identification of Seniors At Risk-Hospitalized Patients (ISAR-HP), and the safety management system (VMS). The primary outcome measure was a composite outcome encompassing functional decline, institutionalization, and mortality at 3 months after ED presentation. Other follow-up time points were 1 and 6 months. Analyses were performed to assess prognostic accuracy. RESULTS: In total, 889 patients were included. After 3 months, 267 (31%) patients experienced at least 1 adverse outcome. The positive likelihood ratio ranged from 1.67 (VMS) to 3.33 (APOP1), and the negative likelihood ratio ranged from 0.41 (ISAR-HP) to 0.88 (APOP2). Sensitivity ranged from 17% (APOP2) to 74% (ISAR-HP), and specificity ranged from 63% (ISAR-HP) to 94% (APOP2). The area under the curve ranged from 0.62 (APOP2) to 0.72 (APOP1 and ISAR-HP). Calibration was reasonable for APOP1 and VMS. The prognostic accuracy was comparable across all outcomes and at all follow-up time points. CONCLUSION: The frailty screening instruments assessed in this study showed poor to moderate prognostic accuracy, which brings into question their usability in the prediction of adverse health outcomes among older adults who present to the ED.

BACKGROUND: Societal expenditures on work-disability benefits is high in most Western countries. As a precursor of long-term work restrictions, long-term sickness absence (LTSA) is under continuous attention of policy makers. Different healthcare professionals can play a role in identification of persons at risk of LTSA but are not well trained. A risk prediction model can support risk stratification to initiate preventative interventions. Unfortunately, current models lack generalizability or do not include a comprehensive set of potential predictors for LTSA. This study is set out to develop and validate a multivariable risk prediction model for LTSA in the coming year in a working population aged 45-64 years. METHODS: Data from 11,221 working persons included in the prospective Study on Transitions in Employment, Ability and Motivation (STREAM) conducted in the Netherlands were used to develop a multivariable risk prediction model for LTSA lasting ≥28 accumulated working days in the coming year. Missing data were imputed using multiple imputation. A full statistical model including 27 pre-selected predictors was reduced to a practical model using backward stepwise elimination in a logistic regression analysis across all imputed datasets. Predictive performance of the final model was evaluated using the Area Under the Curve (AUC), calibration plots and the Hosmer-Lemeshow (H&L) test. External validation was performed in a second cohort of 5604 newly recruited working persons. RESULTS: Eleven variables in the final model predicted LTSA: older age, female gender, lower level of education, poor self-rated physical health, low weekly physical activity, high self-rated physical job load, knowledge and skills not matching the job, high number of major life events in the previous year, poor self-rated work ability, high number of sickness absence days in the previous year and being self-employed. The model showed good discrimination (AUC 0.76 (interquartile range 0.75-0.76)) and good calibration in the external validation cohort (H&L test: p = 0.41). CONCLUSIONS: This multivariable risk prediction model distinguishes well between older workers with high- and low-risk for LTSA in the coming year. Being easy to administer, it can support healthcare professionals in determining which persons should be targeted for tailored preventative interventions.

Research on sex differences related to cardiovascular dysfunction has become a topic of interest in the last decade. Although scientific research has been carried out since ancient times, we still may struggle with performing scientific research in the best way to achieve the highest quality data and solid conclusions. In this chapter, every step of scientific research is explained: from formulating the research question and hypotheses to analyzing the collected data to interpreting and reporting the results. Several fundamental biostatistical techniques-such as the independent samples t-test, the chi-square test, the log-rank test, and different regression models-are presented. In addition, methods that can deal with variables influencing the association of interest are discussed. All examples are focused on investigating sex differences in cardiac outcomes, but this chapter is written in such a way that it easily translates to other fields of medical research on every disease or health state.

Objective: To assess the efficacy and safety of initial COBRA-light vs COBRA therapy in RA patients after a 4-year follow-up period. Methods: In the COBRA-light trial, 162 consecutive patients with recent-onset RA were randomized to either COBRA-light (prednisolone and MTX) or COBRA therapy (prednisolone, MTX and SSZ) for 1 year. After 1 year, treatment was continued without protocol, and adjusted by the treating physician according to clinical judgement, preferably with a treat-to-target strategy. Four years after trial initiation, all patients were invited to participate in the COBRA-light extension study, in which patients were interviewed and physically examined, patient reported outcomes were assessed, radiographs were made and clinical records were examined for comorbidities and medication use. Results: In the extension study, 149 out of 162 (92%) original trial patients participated: 72 COBRA-light and 77 COBRA patients. Initial COBRA-light and COBRA therapy showed similar effect on disease activity, physical functioning, radiological outcome and Boolean remission over the 4-year follow-up period. In addition, both treatment groups showed similar survival and major comorbidities, although the power to detect differences was limited. Besides protocolled differences in prednisolone, MTX and SSZ use, the use of other synthetic and biologic DMARDs and intra-articular and intramuscular glucocorticoid injections was similar in both treatment groups over the 4-year period. Conclusion: Early RA patients initially treated with COBRA-light or COBRA therapy had similar efficacy and safety outcomes over a 4-year follow-up period.

BACKGROUND: Medical students from ethnic minorities underperform in knowledge and skills assessments both in pre-clinical and clinical education compared to the ethnic majority group. Motivation, which influences learning and academic performance of medical students, might play an important role in explaining these differences, but is under-investigated. This study aimed to compare two types of motivation (autonomous and controlled) of ethnic minority (Western and non-Western) and majority (Dutch) students, and their association with academic performance. METHODS: In a cross-sectional study, all students of a Dutch medical school were invited to complete a survey including the Academic Self-Regulation Questionnaire, measuring autonomous and controlled motivation, in the academic year 2015-2016. Motivation was compared using Kruskal-Wallis test and performance was compared using One-Way ANOVA. Linear regression analysis was used to determine the association between motivation and performance (grade point average; GPA). RESULTS: The response rate was 38.6% (n = 947). Autonomous motivation (AM) of non-Western students was higher than that of Dutch students in pre-clinical and clinical education (p < 0.05). Controlled motivation was higher in Western students than in Dutch students (pre-clinical education; p < 0.05). AM was associated with a higher GPA for Dutch (pre-clinical education; ß = 0.33, p < 0.05) and Western students (clinical education; ß = 0.57, p < 0.05) only. CONCLUSIONS: Our results show significant differences in the type of motivation between the ethnic majority and minority groups. The association of motivation with performance also differs between ethnic groups. We found that AM has a positive influence on GPA. Further research is needed to uncover the underlying mechanisms.

OBJECTIVE: To investigate the effect of two different high-dose, step-down prednisolone regimens on body composition in early RA patients after 26 weeks of treatment. METHODS: Prednisolone-naive patients with recent-onset RA (n = 108) were randomized to either COBRA (prednisolone 60 mg/day, tapered to 7.5 mg/day in 6 weeks; MTX and SSZ) or COBRA-light therapy (prednisolone 30 mg/day, tapered to 7.5 mg/day in 8 weeks and MTX). Body composition was assessed at baseline (before or soon after start of treatment) and after 26 weeks with DXA, and recorded as total body mass (TBM), total fat mass (FM), total lean mass (LM) and trunk/peripheral fat ratio. Log-ratio analyses assessed the proportional distribution of TBM (between LM, FM and bone mass) and FM (between trunk, extremities and head). The subgroup of patients with a DXA before start of treatment (n = 38) was analysed separately. RESULTS: In the subgroup of patients with a DXA before start of treatment, TBM increased by 1.6 kg (P < 0.001) and total FM by 1.3 kg (P < 0.001). The trunk/peripheral fat ratio and the proportional distribution of TBM and FM remained stable over time. There were no differences between the treatment groups. Similar results were obtained in the study population as a whole. CONCLUSION: Both high-dose, step-down prednisolone regimens caused increases in TBM, mainly caused by an increase in FM, but we found no fat redistribution from peripheral to central tissues. This absence in fat redistribution contradicts the widely held assumption of rapid adverse effects of prednisolone on body composition in RA.

BACKGROUND: Recently, we documented the likely non-inferiority of Combinatietherapie Bij Reumatoïde Artritis (COBRA)-light therapy (methotrexate increased to 25â mg/week with initial prednisolone 30â mg/day) compared with the original COBRA therapy (methotrexate 7.5â mg/week, sulfasalazine 2â g/day, with initial prednisolone 60â mg/day) after 26â weeks in patients with early active rheumatoid arthritis (RA). OBJECTIVE: To assess the non-inferiority of COBRA-light versus COBRA after 1â year in terms of disease activity (DAS44), functional outcome (Health Assessment Questionnaire (HAQ)) and radiographic progression (Sharp/van der Heijde score (SHS)), and to assess the effect of adding etanercept. METHODS: An open-label, randomised controlled, non-inferiority trial of 162 patients with active early RA, following a treat-to-target protocol incorporating the addition of etanercept if DAS44 ≥1.6 at weeks 26 or 39. RESULTS: Both groups showed major improvements in DAS44 after 52â weeks: mean (SD) -2.41 (1.2) in the COBRA and -2.02 (1.0) in the COBRA-light group (p=ns). In both groups, functional ability improved and radiological progression of joints was minimal. At least one adverse event was reported in 96% of the patients in both groups. In total, 25 serious adverse events occurred: 9 vs 16 in COBRA and COBRA-light, respectively. Treatment actually instituted was often less intensive than required by the protocol: of the total population, 108 patients (67%) required etanercept (more in the COBRA-light group), but only 67 of these (62%) actually received it. CONCLUSIONS: Intensive COBRA or COBRA-light therapy has major, comparably favourable effects on disease activity, functional ability and radiological outcome after 1â year in patients with early RA. Protocolised addition of etanercept was often not implemented by treating rheumatologists, and patients receiving it appeared to have limited added benefit, probably because of low disease activity levels at its initiation.

OBJECTIVES: To review systematically the effect of biological treatment in patients with ankylosing spondylitis (AS) on three work outcomes: work status, absence from paid work and at-work productivity. METHODS: A systematic literature search was performed (Pubmed, Embase, Cochrane Library) to identify relevant articles. Risk of bias of included studies was assessed using the Cochrane guidelines for cohorts and randomised controlled trials (RCTs). Data were extracted using a self-composed data extraction form. Owing to extensive interstudy heterogeneity, narrative summaries were used to present the data. RESULTS: Nine studies were included (six uncontrolled cohorts, one population-controlled cohort and two RCTs) that reported on 39 comparisons. Overall, 961 patients were treated with three different tumour necrosis factor α inhibitors (etanercept, infliximab, adalimumab). For presenteeism and absence from work, most comparisons showed improvement in favour of biological agents, but not all comparisons were statistically significant and they usually concerned before-after analyses. For work status, changes were less often positive, but studies dealt with patients with longstanding AS, lacked power and had a relatively short follow-up. CONCLUSIONS: Although trends towards beneficial effects of biological agents in longstanding AS were seen on all work outcomes, the methodological limitations in the studies included hampers clear conclusions. Since the majority of studies were (extensions of) controlled trials, the generalisability of the effect of biological agents on work participation in real life should be further studied in larger (population-controlled) studies. The effect of biological agents in patients with early disease has not yet been examined.

OBJECTIVE: We developed a smartphone application for patients with rheumatoid arthritis (RA) that allows them to self-monitor their disease activity in between clinic visits by answering a weekly Routine Assessment of Patient Index Data 3. This study was undertaken to assess the safety (noninferiority in the Disease Activity Score in 28 joints using the erythrocyte sedimentation rate [DAS28-ESR]) and efficacy (reduction in number of visits) of patient-initiated care assisted using a smartphone app, compared to usual care. METHODS: A 12-month, randomized, noninferiority clinical trial was conducted in RA patients with low disease activity and without treatment changes in the past 6 months. Patients were randomized 1:1 to either app-supported patient-initiated care with a scheduled follow-up consultation after a year (app intervention group) or usual care. The coprimary outcome measures were noninferiority in terms of change in DAS28-ESR score after 12 months and the ratio of the mean number of consultations with rheumatologists between the groups. The noninferiority limit was 0.5 difference in DAS28-ESR between the groups. RESULTS: Of the 103 randomized patients, 102 completed the study. After a year, noninferiority in terms of the DAS28-ESR score was established, as the 95% confidence interval (95% CI) of the mean ΔDAS28-ESR between the groups was within the noninferiority limit: -0.04 in favor of the app intervention group (95% CI -0.39, 0.30). The number of rheumatologist consultations was significantly lower in the app intervention group compared to the usual care group (mean ± SD 1.7 ± 1.8 versus 2.8 ± 1.4; visit ratio 0.62 [95% CI 0.47, 0.81]). CONCLUSION: Patient-initiated care supported by smartphone self-monitoring was noninferior to usual care in terms of the ΔDAS28-ESR and led to a 38% reduction in rheumatologist consultations in RA patients with stable low disease activity.
