The effect of a goal-setting strategy with integrated feedback on goal attainment in inflammatory arthritis patients: a mixed method study.

Patients with Inflammatory Arthritis (IA) often experience difficulties in daily life as a result of their disease. Unfortunately, outpatient consultations in daily practice tend to focus on medical topics, thereby ignoring the impact of the disease on patients' daily lives. Patient-Reported Outcomes (PROs) can be used to understand this impact, but they are not enough for offering person-centered care. Because the patient's true values and goals can only be ascertained during a proper conversation, which should include both medical as well as patient goals. Therefore, the aim of the study is to evaluate the effect of a goal management strategy with integrated feedback on goal attainment and Health-Related Quality of Life(HRQoL) in IA patients. IA patients with an active disease were given the opportunity to set and follow-up goals. In addition to goal setting, patients were asked to complete online questionnaires on various PROs, including HRQoL. Ninety-two IA patients participated in the study. The mean age was 51 years and most of them had rheumatoid arthritis. A total of 302 patient goals were set, of which 32% were achieved. In the entire population, HRQoL did not change over time, but patients who did not meet their goals tended to report a lower HRQoL. Incorporating a feedback mechanism in a goal-setting strategy has a positive effect on goal attainment. Yet no effect was seen on HRQoL, but this may due to the fact that general HRQoL measurement are not sensitive or specific enough to detect changes that are accompanied with goal setting and attainment.

Arthroscopic synovectomy versus intra-articular injection of corticosteroids for the management of refractory psoriatic or rheumatoid arthritis of the wrist: study protocol for a randomized controlled trial (ARCTIC trial).

BACKGROUND: Rheumatoid arthritis (RA) and psoriatic arthritis (PsA) are inflammatory diseases that often affect the wrist and, when affected, can lead to impaired wrist function and progressive joint destruction if inadequately treated. Standard care consists primarily of disease-modifying anti-rheumatic drugs (DMARDs), often supported by systemic corticosteroids or intra-articular corticosteroid injections (IACSI). IACSI, despite their use worldwide, show poor response in a substantial group of patients. Arthroscopic synovectomy of the wrist is the surgical removal of synovitis with the goal to relieve pain and improve wrist function. The primary objective of this study is to evaluate wrist function following arthroscopic synovectomy compared to IACSI in therapy-resistant patients with rheumatoid or psoriatic arthritis. Secondary objectives include radiologic progress, disease activity, health-related quality of life, work participation and cost-effectiveness during a 1-year follow-up. METHODS: This protocol describes a prospective, randomized controlled trial. RA and PsA patients are eligible with prominent wrist synovitis objectified by a rheumatologist, not responding to at least 3 months of conventional DMARDs and naïve to biological DMARDs. For 90% power, an expected loss to follow-up of 5%, an expected difference in mean Patient-Rated Wrist Evaluation score (PRWE, range 0-100) of 11 and α = 0.05, a total sample size of 80 patients will be sufficient to detect an effect size. Patients are randomized in a 1:1 ratio for arthroscopic synovectomy with deposition of corticosteroids or for IACSI. Removed synovial tissue will be stored for an ancillary study on disease profiling. The primary outcome is wrist function, measured with the PRWE score after 3 months. Secondary outcomes include wrist mobility and grip strength, pain scores, DAS28, EQ-5D-5L, disease progression on ultrasound and radiographs, complications and secondary treatment. Additionally, a cost-effectiveness analysis will be performed, based on healthcare costs (iMCQ questionnaire) and productivity loss (iPCQ questionnaire). Follow-up will be scheduled at 3, 6 and 12 months. Patient burden is minimized by combining study visits with regular follow-ups. DISCUSSION: Persistent wrist arthritis continues to be a problem for patients with rheumatic joint disease leading to disability. This is the first randomized controlled trial to evaluate the effect, safety and feasibility of arthroscopic synovectomy of the wrist in these patients compared to IACSI.

Unraveling heterogeneity within ACPA-negative rheumatoid arthritis: the subgroup of patients with a strong clinical and serological response to initiation of DMARD treatment favor disease resolution.

BACKGROUND: Rheumatoid arthritis (RA) is a heterogeneous disease, as evidenced by the differences in long-term outcomes. This applies especially to anti-citrullinated protein antibodies (ACPA)-negative RA, where a proportion achieves sustained DMARD-free remission (SDFR; sustained absence of synovitis after DMARD cessation). Differentiation of RA patients who will achieve SDFR can guide personalized treatment/tapering strategies. Although this subgroup remains scarcely discerned, previous research demonstrated that these RA patients are characterized by an early clinical response (DAS remission after 4 months) after DMARD start. We studied whether, in addition to this clinical response, a specific biomarker response can further distinguish the subgroup of RA patients most likely to achieve SDFR. METHODS: In 266 RA patients, levels of 12 biomarkers (SAA/CRP/MMP-1/MMP-3/resistin/leptin/IL-6/TNF-R1/YKL-40/EGF/VEGF/VCAM-1), in the first 2 years after diagnosis, were studied in relation to SDFR, stratified for ACPA status. Subsequently, biomarkers associated with SDFR development were combined with early DAS remission to study its additional value in defining subgroups. Since most biomarker levels are not routinely measured in clinical practice, we explored how this subgroup can be clinically recognized. RESULTS: ACPA-negative RA patients achieving SDFR were characterized by high baseline levels and stronger decline in MMP-1/MMP-3/SAA/CRP after DMARD-start, respectively 1.30×/1.44×/2.12×/2.24× stronger. This effect was absent in ACPA-positive RA. In ACPA-negative RA, a strong biomarker decline is associated with early DAS remission. The combination of both declines (clinical, biomarker) was present in a subgroup of ACPA-negative RA patients achieving SDFR. This subgroup can be clinically recognized by the combination of high baseline CRP levels (≥ 3 times ULN), and early DAS remission (DAS4 months < 1.6). This latter was replicated in independent ACPA-negative RA patients. CONCLUSIONS: ACPA-negative RA patients with early DAS remission and a strong biomarker response (or baseline CRP levels ≥ 3× ULN) are most likely to achieve SDFR later on. This could guide personalized decisions on DMARD tapering/cessation in ACPA-negative RA.

The number of risk factors for persistent disease determines the clinical course of early arthritis.

OBJECTIVES: Management of early arthritis is based upon early recognition of individuals at high risk of developing persistent arthritis. Therefore, this study investigates whether the number of risk factors for persistent disease or treatment determines the clinical course of early arthritis by comparing the chance at (sustained) DMARD-free remission ((S)DFR) after 2 years follow-up. METHODS: Data from the tREACH trial, a stratified single-blinded multicentre strategy trial with a treat-to-target approach were used. We selected all patients with ≥1 swollen joint who did not fulfil 1987 and/or 2010 criteria for RA. The number of risk factors present; autoantibody-positivity, polyarthritis (>4), erosive disease and elevated acute phase reactants, determined risk group stratification. Multivariate logistic regression analyses were performed with (S)DFR as dependent variables and baseline disease activity score (DAS), treatment, symptom duration and number of risk factors present as independent variables. RESULTS: In total, 130 early arthritis patients were included and respectively 31, 66 and 33 had 0, 1 and ≥2 risk factors present. DFR rates were respectively 74%, 48% and 45% for early arthritis patients with 0, 1 and ≥2 risk factors present. In accordance SDFR rates were 61%, 32% and 30%. In our logistic model (S)DFR was not influenced by the initial treatment strategies when stratified for risk groups. CONCLUSION: The chance at (S)DFR in early arthritis diminishes when more risk factors are present, which is irrespective of the given initial treatment. Our data point out to a stratified management approach in early arthritis based on their risk profile, but validation is needed.

DMARD-free remission as novel treatment target in rheumatoid arthritis: A systematic literature review of achievability and sustainability.

OBJECTIVES: Although current treatment guidelines for rheumatoid arthritis (RA) suggest tapering disease-modifying anti-rheumatic drugs (DMARDs), it is unclear whether DMARD-free remission (DFR) is an achievable and sustainable outcome. Therefore, we systematically reviewed the literature to determine the prevalence and sustainability of DFR and evaluated potential predictors for DFR. METHODS: A systematic literature search was performed in March 2019 in multiple databases. All clinical trials and observational studies reporting on discontinuation of DMARDs in RA patients in remission were included. Our quality assessment included a general assessment and assessment of the description of DFR. Prevalence of DFR and its sustainability and flares during tapering and after DMARD stop were summarised. Also, potential predictors for achieving DFR were reviewed. RESULTS: From 631 articles, 51 were included, comprising 14 clinical trials and 5 observational studies. DFR definition differed, especially for the duration of DMARD-free state. Considering only high- and moderate-quality studies, DFR was achieved in 5.0%-24.3% and sustained DFR (duration>12 months) in 11.6%-19.4% (both relative to the number of patients eligible for tapering). Flares occurred frequently during DMARD tapering (41.8%-75.0%) and in the first year after achieving DFR (10.4%-11.8%), while late flares, >1 year after DMARD-stop, were infrequent (0.3%-3.5%). Many patient characteristics lacked association with DFR. Absence of autoantibodies and shared epitope alleles increased the chance of achieving DFR. CONCLUSIONS: DFR is achievable in RA and is sustainable in ~10%-20% of patients. DFR can become an important outcome measure for clinical trials and requires consistency in the definition. Considering the high rate of flares in the first year after DMARD stop, a DMARD-free follow-up of >12 months is advisable to evaluate sustainability.

The impact of a disease flare during tapering of DMARDs on the lives of rheumatoid arthritis patients.

OBJECTIVES: To determine the impact of a disease flare on patient reported outcome measures (PROMs) in rheumatoid arthritis (RA) patients, who are tapering treatment. METHODS: Data were used from the TARA trial; a multicenter, randomized controlled trial in which RA patients, with a well-controlled disease (DAS≤2.4 and SJC≤1) for at least 6 months, gradually tapered their DMARDs. PROMs of patients with a flare (DAS>2.4 and/or SJC>1) were compared every three months before and after a flare with their own norm values. Linear Mixed Models were used to investigate whether a disease flare influenced functional ability (HAQ-DI), fatigue (BRAF-MDQ), quality of life (EQ-5D and SF36), anxiety and depression (HADS), morning stiffness, general health (GH) and worker productivity, and if so, the duration was determined. For unemployment and sick leave we used descriptive statistics. RESULTS: A flare negatively influenced GH, morning stiffness, HAQ-DI, EQ-5D, BRAF-MDQ, and the SF36 physical component scale and this effect lasted >3 months. Except for the HAQ-DI, effect sizes exceeded the minimum clinically important differences (MCIDs). For the physical outcomes effects lasted >6 months. Worker productivity was not significantly affected by a flare. CONCLUSION: A disease flare influenced patients' lives, the largest effect was seen in the physical outcomes, and lasted 6 months. Although on a group level effect sizes for the separate PROMs were not always significant or larger than specific MCIDs, a disease flare can still be of great importance for individual patients.

Tapering conventional synthetic DMARDs in patients with early arthritis in sustained remission: 2-year follow-up of the tREACH trial.

OBJECTIVES: With early and intensive treatment many patients with early RA attain remission. Aims were to investigate (1) the frequency and time to sustained remission and subsequent tapering in patients initially treated with conventional synthetic disease modifying anti-rheumatic drug ((cs)DMARD) strategies and (2) the frequency and time to flare and regained remission in patients tapering csDMARDs and biological (b)DMARDs during 2 years of follow-up. METHODS: Two-year follow-up data from the treatment in the Rotterdam Early Arthritis Cohort (tREACH) cohort were used. Patients were randomised to initial treatment with triple DMARD therapy (iTDT) with glucocorticoid (GC) bridging or methotrexate monotherapy (iMM) with GC bridging. Patients were evaluated every 3 months. In case Disease Activity Score (DAS) was >2.4 treatment was switched to a TNF-blocker. In case DAS<1.6 at 2 consecutive time points, tapering was initiated according to protocol. Outcomes were rates of sustained remission (DAS<1.6 at 2 consecutive time points), flare (medication increase after tapering) and remission after flare (DAS<1.6). Data were analysed using Kaplan-Meier analyses. RESULTS: During 2 years of follow-up, sustained remission was achieved at least once by 159 (57%) of patients, of whom 118 and 23 patients initiated tapering of csDMARDs and bDMARDs, respectively. Thirty-four patients achieved drug-free remission. Flare rates were 41% and 37% and within 1 year, respectively. After flare, 65% of patients tapering csDMARDs re-achieved remission within 6 months after treatment intensification. CONCLUSIONS: Regardless of initial treatment strategy, 57% of patients achieved sustained remission during 2 years of follow-up. Flare rates were 41% and 37% within 12 months in patients tapering csDMARDs and bDMARDs, respectively. TRIAL REGISTRATION NUMBER: ISRCTN26791028; Post-results.

Association of low baseline levels of erythrocyte folate with treatment nonresponse at three months in rheumatoid arthritis patients receiving methotrexate.

OBJECTIVE: To investigate whether baseline concentrations of one-carbon metabolism biomarkers are associated with treatment nonresponse and adverse events in rheumatoid arthritis (RA) patients receiving methotrexate (MTX). METHODS: A prospective derivation cohort (n = 285) and validation cohort (n = 102) of RA patients receiving MTX were studied. Concentrations of plasma homocysteine, serum vitamin B12 , serum folate, erythrocyte vitamin B6 , and erythrocyte folate were determined at baseline and after 3 months of treatment. Nonresponse after 3 months was assessed using the Disease Activity Score in 28 joints (DAS28) and the European League Against Rheumatism (EULAR) response criteria. Adverse events at 3 months were assessed using biochemical parameters and health status questionnaires. Analyses were corrected for baseline DAS28, age, sex, MTX dose, comedications, and presence of the methylenetetrahydrofolate reductase 677TT genotype. RESULTS: In the derivation cohort, the mean DAS28 scores at baseline and 3 months were 4.94 and 3.12, respectively, and 78% of patients experienced adverse events. This was similar between the 2 cohorts, despite a lower MTX dose in the validation cohort. Patients with lower levels of erythrocyte folate at baseline had a higher DAS28 at 3 months in both the derivation cohort (ß = -0.15, P = 0.037) and the validation cohort (ß = -0.20, P = 0.048). In line with these results, lower baseline erythrocyte folate levels were linearly associated with a 3-month DAS28 of >3.2 in both cohorts (derivation cohort, P = 0.049; validation cohort, P = 0.021) and with nonresponse according to the EULAR criteria (derivation cohort, P = 0.066; validation cohort, P = 0.027). None of the other biomarkers (levels at baseline or changes over 3 months) were associated with the DAS28 or treatment nonresponse. Baseline levels of the biomarkers and changes in levels after 3 months were not associated with incidence of adverse events. CONCLUSION: A low baseline concentration of erythrocyte folate is associated with high disease activity and nonresponse at 3 months after the start of MTX treatment and could be used in prediction models for MTX outcome. None of the investigated one-carbon metabolism biomarkers were associated with incidence of adverse events at 3 months.

[Hyponatraemia as a clinical manifestation of hypopituitarism caused by neurosarcoidosis]. / Hyponatriëmie als klinische manifestatie van hypopituïtarisme door neurosarcoïdose.

Severe hyponatraemia was observed in a 35-year-old man with progressive malaise; this was caused by hypopituitarism and secondary hypocortisolism as a result ofneurosarcoidosis. Sarcoidosis is a multisystem granulomatous disorder of unknown aetiology which can develop in any of the body's organs or tissues. The central nervous system is affected in only 5-15% of patients with sarcoidosis. Neurosarcoidosis is a rare disorder with clinical heterogeneity. Extensive diagnostic procedures, including MRI of the cerebrum and histological investigation, and structural outpatient follow-up are mandatory in patients in whom neurosarcoidosis is suspected. Treatment consists mainly of high-dose corticosteroids, which usually have to be taken long-term. Clinical course and prognosis are variable, and depend on the accompanying symptoms.
