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.

Objectives The aim of this study was to assess the safety and efficacy of long-term low-dose glucocorticoids (GCs) in RA. Methods A protocolised systematic review and meta-analysis (PROSPERO No. CRD42021252528) of double-blind, placebo-controlled randomised trials (RCTs) comparing a low dose of GCs (≤ 7.5mg/day prednisone) to placebo over at least 2 years was performed. The primary outcome investigated was adverse events (AEs). We performed random-effects meta-analyses and used the Cochrane RoB tool and GRADE to assess risk of bias and quality of evidence (QoE). Results Six trials with 1078 participants were included. There was no evidence of an increased risk of AEs (incidence rate ratio 1.08; 95% CI 0.86, 1.34; P  = 0.52); however, the QoE was low. The risks of death, serious AEs, withdrawals due to AEs, and AEs of special interest did not differ from placebo (very low to moderate QoE). Infections occurred more frequently with GCs (risk ratio 1.4; 1.19–1.65; moderate QoE). Concerning benefit, we found moderate to high quality evidence of improvement in disease activity (DAS28: −0.23; −0.43 to −0.03), function (HAQ −0.09; −0.18 to 0.00), and Larsen scores (–4.61; −7.52 to −1.69). In other efficacy outcomes, including Sharp van der Heijde scores, there was no evidence of benefits with GCs. Conclusion There is very low to moderate QoE for no harm with long-term low dose GCs in RA, except for an increased risk of infections in GC users. The benefit-risk ratio might be reasonable forusing low-dose long-term GCs considering the moderate to high quality evidence for disease-modifying properties. [ABSTRACT FROM AUTHOR]

Objectives To identify highly ranked features related to clinicians' diagnosis of clinically relevant knee OA. Methods General practitioners (GPs) and secondary care physicians (SPs) were recruited to evaluate 5–10 years follow-up clinical and radiographic data of knees from the CHECK cohort for the presence of clinically relevant OA. GPs and SPs were gathered in pairs; each pair consisted of one GP and one SP, and the paired clinicians independently evaluated the same subset of knees. A diagnosis was made for each knee by the GP and SP before and after viewing radiographic data. Nested 5-fold cross-validation enhanced random forest models were built to identify the top 10 features related to the diagnosis. Results Seventeen clinician pairs evaluated 1106 knees with 139 clinical and 36 radiographic features. GPs diagnosed clinically relevant OA in 42% and 43% knees, before and after viewing radiographic data, respectively. SPs diagnosed in 43% and 51% knees, respectively. Models containing top 10 features had good performance for explaining clinicians' diagnosis with area under the curve ranging from 0.76–0.83. Before viewing radiographic data, quantitative symptomatic features (i.e. WOMAC scores) were the most important ones related to the diagnosis of both GPs and SPs; after viewing radiographic data, radiographic features appeared in the top lists for both, but seemed to be more important for SPs than GPs. Conclusions Random forest models presented good performance in explaining clinicians' diagnosis, which helped to reveal typical features of patients recognized as clinically relevant knee OA by clinicians from two different care settings.

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.

Objectives To investigate the dynamics of response of synovitis to IL-17A inhibition with secukinumab in patients with active PsA using Power Doppler ultrasound. Methods The randomized, placebo-controlled, Phase III ULTIMATE study enrolled PsA patients with active ultrasound synovitis and clinical synovitis and enthesitis having an inadequate response to conventional DMARDs and naïve to biologic DMARDs. Patients were randomly assigned to receive either weekly subcutaneous secukinumab (300 or 150 mg according to the severity of psoriasis) or placebo followed by 4-weekly dosing thereafter. The primary outcome was the mean change in the ultrasound Global EULAR and OMERACT Synovitis Score (GLOESS) from baseline to week 12. Key secondary endpoints included ACR 20 and 50 responses. Results Of the 166 patients enrolled, 97% completed 12 weeks of treatment (secukinumab, 99%; placebo, 95%). The primary end point was met, and the adjusted mean change in GLOESS was higher with secukinumab than placebo [−9 (0.9) vs −6 (0.9), difference (95% CI): −3 (−6, −1); one-sided P= 0.004] at week 12. The difference in GLOESS between secukinumab and placebo was significant as early as one week after initiation of treatment. All key secondary endpoints were met. No new or unexpected safety findings were reported. Conclusion This unique ultrasound study shows that apart from improving the signs and symptoms of PsA, IL-17A inhibition with secukinumab leads to a rapid and significant reduction of synovitis in PsA patients.

Objectives Although there is a general focus on early diagnosis and treatment of hip OA, there are no validated diagnostic criteria for early-stage hip OA. The current study aimed to take the first steps in developing diagnostic criteria for early-stage hip OA, using factors obtained through history taking, physical examination, radiography and blood testing at the first consultation in individuals presenting with hip pain, suspicious for hip OA, in primary care. Methods Data of the 543 individuals with 735 symptomatic hips at baseline who had any follow-up data available from the prospective CHECK cohort study were used. A group of 26 clinical experts [general practitioners (GPs), rheumatologists and orthopaedic surgeons] evaluated standardized clinical assessment forms of all subjects on the presence of clinically relevant hip OA 5–10 years after baseline. Using the expert-based diagnoses as reference standard, a backward selection method was used to create predictive models based on pre-defined baseline factors from history taking, physical examination, radiography and blood testing. Results Prevalence of clinically relevant hip OA during follow-up was 22%. Created models contained four to eight baseline factors (mainly WOMAC pain items, painful/restricted movements and radiographic features) and obtained area under the curve between 0.62 (0.002) and 0.71 (0.002). Conclusion Based on clinical and radiographic features of hip OA obtained at first consultation at a GP for pain/stiffness of the hip, the prediction of clinically relevant hip OA within 5–10 years was 'poor' to 'fair'.

Background: To add context to the impact of medical conditions, it is important to interpret and compare health outcomes across studies and populations. We aimed to determine Dutch reference values for the Patient-Reported Outcomes Measurement Information System Scale v1.2 - Global Health (PROMIS-GH). Methods: The PROMIS-GH, also referred to as PROMIS-10, was completed by 4370 Dutch persons, representative for the 2016 Dutch population. T-scores for the mental health (GMH) and physical health (GPH) subscales, and their shorter two-item subscales, were calculated for the entire population, age groups and gender. T-scores for GMH and GPH were compared to the US reference population, representative for the 2000 US general population. Interpretability thresholds for poor, fair, good, very good and excellent GPH and GMH were calculated based on T-scores of participants, which were categorized into five groups based on their response to item Global01. For each group the mean GPH and GMH T-score was calculated and the midpoint between two adjacent means was identified, resulting in thresholds. Thresholds based on the Dutch data were compared to US thresholds. Results: The Dutch population had a GMH T-score of 44.7 and a GPH T-score of 45.2, both substantially worse than the US reference population T-score of 50. Lower T-scores were also found for age-range and gender subpopulations. Dutch GMH and GPH interpretability thresholds were mostly not substantially different compared to the US thresholds, although the Dutch threshold between fair and poor mental health was considerably higher (29 vs. 38). Conclusions: This study reports reference values for the PROMIS-GH scale for the Dutch general population, including age-range and gender subpopulations. These reference values provide an important tool for healthcare professionals and researchers to better evaluate and interpret patient-reported mental health and physical health. Scores are notably worse than the US reference values. The exact reason for this remains subject for further research, although possibilities for the differences are discussed, including the presence of differential item functioning and the representativeness and recentness of the data.

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. [ABSTRACT FROM AUTHOR]

Objective. To assess the 10-year cardiovascular (CV) risk score and to identify treatment and undertreatment of CV risk factors in patients with established RA. Methods. Demographics, CV risk factors and prevalence of cardiovascular disease (CVD) were assessed by questionnaire. To calculate the 10-year CV risk score according to the Dutch CV risk management guideline, systolic blood pressure was measured and cholesterol levels were determined from fasting blood samples. Patients were categorized into four groups: indication for treatment but not treated; inadequately treated, so not meeting goals (systolic blood pressure ≤140mmHg and/or low-density lipoprotein ≤2.5mmol/l); adequately treated; or no treatment necessary. Results. A total of 720 consecutive RA patients were included, 375 from Reade and 345 from the Antonius Hospital. The mean age of patients was 59 years (S.D. 12) and 73% were female. Seventeen per cent of the patients had a low 10-year CV risk (<10%), 21% had an intermediate risk (10-19%), 53% a high risk (≥20%) and 9% had CVD. In total, 69% had an indication for preventive treatment (cholesterol-lowering or antihypertensive drugs). Of those, 42% received inadequate treatment and 40% received no treatment at all. Conclusion. Optimal CV risk management remains a major challenge and better awareness and management are urgently needed to reduce the high risk of CVD in the RA population. [ABSTRACT FROM AUTHOR]

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.

Objective. To evaluate the content validity and measurement properties of the Patient-Reported Outcome Measurement Information System (PROMIS) physical function item bank and a 20-item short form in patients with RA in comparison with the HAQ disability index (HAQ-DI) and 36-item Short Form Health Survey (SF-36) physical functioning scale (PF-10). Methods. The content validity of the instruments was evaluated by linking their items to the International Classification of Functioning, Disability and Health (ICF) core set for RA. The measures were administered to 690 RA patients enrolled in the Dutch Rheumatoid Arthritis Monitoring registry. Measurement precision was evaluated using item response theory methods and construct validity was evaluated by correlating physical function scores with other clinical and patient-reported outcome measures. Results. All 207 health concepts identified in the physical function measures referred to activities that are featured in the ICF. Twenty-three of 26 ICF RA core set domains are featured in the full PROMIS physical function item bank compared with 13 and 8 for the HAQ-DI and PF-10, respectively. As hypothesized, all three physical function instruments were highly intercorrelated (r 0.74-0.84), moderately correlated with disease activity measures (r 0.44-0.63) and weakly correlated with age (rs 0.07-0.14). Item response theory-based analysis revealed that a 20-item PROMIS physical function short form covered a wider range of physical function levels than the HAQ-DI or PF-10. Conclusion. The PROMIS physical function item bank demonstrated excellent measurement properties in RA. A content-driven 20-item short form may be a useful tool for assessing physical function in RA.

Objective To compare rates of sustained low and minimal disease activity and remission according to the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria during 3-year followup in rheumatoid arthritis (RA) patients treated with etanercept and adalimumab in routine care. Methods Four hundred seven RA patients previously unexposed to tumor necrosis factor antagonists were treated with etanercept (n = 203) or adalimumab (n = 204) and assessed at 3- and later 6-month intervals. Treatment allocation was at the discretion of the treating rheumatologist. Clinical parameters were measured at each time point, as were anti-adalimumab antibodies in adalimumab-treated patients. Achievement of clinical outcome was defined as the occurrence of sustained (at least 12 consecutive months) low disease activity (28-joint Disease Activity Score [DAS28] <3.2), minimal disease activity (DAS28 <2.6), or ACR/EULAR remission based on the Simplified Disease Activity Index (SDAI). Non-overlapping response rates were calculated. Results Among the adalimumab group, 13% reached sustained low disease activity but not sustained minimal disease activity, 15% reached sustained minimal disease activity but not sustained remission according to the SDAI, and 16% reached sustained ACR/EULAR remission. In the etanercept group the corresponding rates were 16%, 11%, and 12%, respectively ( P = 0.42, overall test for linear trend). Adalimumab-treated patients without anti-adalimumab antibodies (n = 150 [74%]) had the best outcomes, and adalimumab-treated patients with anti-adalimumab antibodies the worst, with outcomes in etanercept-treated patients in between ( P < 0.0001). Differences were most apparent in the sustained SDAI remission and sustained minimal disease activity categories. For example, 40% of anti-adalimumab antibody-negative patients, 23% of etanercept-treated patients, and 4% of anti-adalimumab antibody-positive patients achieved at least sustained minimal disease activity. Conclusion Overall, etanercept and adalimumab treatment appear similar in inducing a good long-term clinical outcome. However, in the case of adalimumab this is strongly dependent on the presence or absence of anti-adalimumab antibodies. [ABSTRACT FROM AUTHOR]

Objective. To compare the effects of aggressive tight control therapy and conventional care on radiographic progression and disease activity in patients with early mild inflammatory arthritis.Methods. Patients with two to five swollen joints, Sharp–van der Heijde radiographic score (SHS) <5 and symptom duration &leq;2 years were randomized between two strategies. Patients with a definite non-RA diagnosis were excluded. The protocol of the aggressive group aimed for remission (DAS < 1.6), with consecutive treatment steps: MTX, addition of adalimumab and combination therapy. The conventional care group followed a strategy with traditional DMARDs (no prednisone or biologics) without DAS-based guideline. Outcome measures after 2 years were SHS (primary), remission rate and HAQ score (secondary).Results. Eighty-two patients participated (60% ACPA positive). In the aggressive group (n = 42), 19 patients were treated with adalimumab. In the conventional care group (n = 40), 24 patients started with hydroxychloroquin (HCQ), 2 with sulfasalazine (SSZ) and 14 with MTX. After 2 years, the median SHS increase was 0 [interquartile range (IQR) 0–1.1] and 0.5 (IQR 0–2.5), remission rates were 66 and 49% and HAQ decreased with a mean of −0.09 (0.50) and −0.25 (0.59) in the aggressive and conventional care group, respectively. All comparisons were non-significant.Conclusion. In patients with early arthritis of two to five joints, both aggressive tight-control therapy including adalimumab and conventional therapy resulted in remission rates around 50%, low radiographic damage and excellent functional status after 2 years. However, full disease control including radiographic arrest in all patients remains an elusive target even in moderately active early arthritis.Trial registration.
