Treat-to-target as an approach in inflammatory arthritis

Comparison and Influence of a Multicomponent Educational Program on the Patient-Reported Outcomes of a Group of Patients With Rheumatoid Arthritis

BACKGROUND

Rheumatoid arthritis (RA) is a chronic disease that affects different areas of the patient's body. Patient education and health literacy is essential for them to participate actively in follow-up.

OBJECTIVES

The aim of this study was to assess differences between clinimetric measurements done by a medical team and patient-reported outcome measures (PROMs) in RA and understand the impact of patient education strategies in order to identify differences between RA assessment methods.

METHODS

This is a longitudinal cohort study. It included adult patients with RA and access to digital tools. These were divided into 3 groups by type of education. Group 1 included patients who participated in a multicomponent RA educational program. Group 2 did not have this multicomponent RA education. Group 3 did not receive any education. The 3 groups performed PROMs. Disease activity scales, functional class, and quality of life were measured. Univariate and bivariate analysis (χ2 and Wilcoxon for paired data) were done.

RESULTS

Twenty-eight patients were included in group 1, 26 in group 2, and 37 in group 3. All were women. In group 1, there were no significant differences in clinimetrics between the medical team and patient's PROMs except for fatigue. In group 2 and group 3, significant differences were found. The RAPID3 and PAS variables did not show significant differences when analyzed by intervention subgroups.

CONCLUSIONS

This study shows no differences between clinimetrics/PROMs for patients with a high-level education on RA and physicians. On the other hand, when patient did not have any RA education, the clinimetric results differed from physician measurement.

Patients' experience of a novel interdisciplinary nurse-led self-management intervention (INSELMA)-a qualitative evaluation

BACKGROUND

Despite continuous improvements in anti-rheumatic pharmacological treatment, people with chronic inflammatory arthritis still report substantial disease impact. Based on the framework for complex interventions, we thus developed INSELMA, a novel nurse-coordinated multidisciplinary self-management intervention for patients with rheumatoid arthritis, psoriatic arthritis or axial spondyloarthritis. Based on individual biopsychosocial assessments, a rheumatology nurse facilitated goal setting and coordinated interdisciplinary support. The aim of this study was to explore the patients' experience of participating in the six-months INSELMA intervention.

METHODS

Individual semi-structured interviews were conducted with 15 of the participants after their final follow-up. Thematic analysis was applied.

RESULTS

The analysis derived four overall themes. (1) A new opportunity at the right time. The participants' disease impacted all areas of daily life. Participation in INSELMA was experienced as an opportunity to improve symptoms and together reduce long-held challenges they had fought alone, until now. (2) The importance of person-centred goals. The participants found it meaningful to work with their individual goals, which encompassed physical, psychological, and social factors. Having time between consultations to work with goals at home was important. (3) Empathy, partnership and a little nudging from health professionals are essential. The empathic nurses' continuous support and coaching helped participants become aware of their own resources. The participants highlighted having access to support from a physiotherapist and occupational therapist with rheumatology experience as important. (4) I got more than I could have hoped for. Most of the participants experienced decreased symptom load and improvement in physical strength, mobility, sleep, and mood as well as increased energy, knowledge, and self-management ability. The participants expressed new hope for the future with an improved ability to manage their symptoms and work towards new goals.

CONCLUSION

The participants found the INSELMA intervention meaningful and feasible. They experienced decreased disease impact and increased activity levels, facilitated by empathy and self-management support from health professionals.

Development of a complex Interdisciplinary Nurse-coordinated SELf-MAnagement (INSELMA) intervention for patients with inflammatory arthritis

BACKGROUND

Apart from a consistent focus on treating inflammation, patients with inflammatory arthritis (IA) report a range of unmet needs. Many experience not only residual symptoms but also various other physical, psychological, and social effects. Therefore, this study aimed to develop a complex Interdisciplinary Nurse-coordinated self-management (INSELMA) intervention for patients with IA, as an add-on treatment to usual outpatient care for those with substantial disease impact.

METHODS

This study followed the British Medical Research Council's updated framework for developing complex interventions. The process encompassed the following steps: (1) The evidence base was identified; (2) workshops were held, involving 38 relevant stakeholders (managers, physicians, nurses, physiotherapists, occupational therapists, social workers, psychologists from hospitals and municipalities, and two patient research partners), to discuss and further develop the preliminary ideas; (3) relevant theories were identified (i.e., self-efficacy, acceptance and commitment therapy, and health literacy); (4) the intervention was modeled and remodeled and (5) the results, describing the final INSELMA intervention and outcomes.

RESULTS

The INSELMA intervention encompasses an initial biopsychosocial assessment, which is performed by a rheumatology nurse. Then, activities that the participant wishes to improve are identified and goals are set. The nurse refers the participant to a multidisciplinary team and coordinates their support and relevant services in the participant's municipality. In addition, the health professionals have the opportunity to hold two interdisciplinary conferences during the intervention period. The participant and the health professionals work to achieve the set goals during a 6-month period, which ends with a status assessment and a discussion of further needs. The INSELMA intervention aims to increase self-management, reduce the impact of IA (e.g., pain, fatigue, sleep problems, and absenteeism), and increase self-efficacy, quality of life, mental well-being, work ability, and physical activity.

CONCLUSIONS

The development of the INSELMA intervention involved stakeholders from two Danish rheumatology outpatient clinics, patient research partners and municipalities. We believe that we have identified important mechanisms to increase the self-management and quality of life of people with IA and to decrease the disease impact in those who are substantially affected. The health professionals involved have developed competences in delivering the intervention and it is ready to be tested in a feasibility study.

Comparative Effectiveness, Time to Discontinuation, and Patient-Reported Outcomes with Baricitinib in Rheumatoid Arthritis: 2-Year Data from the Multinational, Prospective Observational RA-BE-REAL Study in European Patients

INTRODUCTION

RA-BE-REAL is a 3-year, multinational, prospective, observational study of adult patients with rheumatoid arthritis (RA) evaluating time to discontinuation of initial RA treatment along with patient baseline characteristics. This study's primary objective was to assess the time to discontinuation of initial baricitinib, any other targeted synthetic disease-modifying anti-rheumatic drug (tsDMARD), or any biologic disease-modifying anti-rheumatic drug (bDMARD) treatment for all causes (excluding sustained clinical response) over 24 months in a European population.

METHODS

Patients initiated treatment with baricitinib (cohort A) or any bDMARD or tsDMARD (cohort B) for the first time. This study's primary objective was to assess the time to discontinuation of initial baricitinib, any other targeted synthetic disease-modifying anti-rheumatic drug (tsDMARD), or any biologic disease-modifying anti-rheumatic drug (bDMARD) treatment for all causes (excluding sustained clinical response) over 24 months in a European population. Comparative effectiveness analyses, over 24 months, included time to treatment discontinuation for all causes (excluding sustained clinical response), percentage of patients achieving Clinical Disease Activity Index (CDAI) remission or low disease activity (LDA), as well as mean changes from baseline for CDAI, pain visual analogue scale, and the Health Assessment Questionnaire-Disability Index (HAQ-DI). For this European subpopulation, comparative analyses were performed using a frequentist model averaging (FMA) framework based on a data-driven machine learning causal inference approach to compare time to discontinuation, effectiveness, rates of remission or LDA, and patient-reported outcomes over 24 months comparing baricitinib with TNFi, as well as non-TNFi and tsDMARD grouped as other mechanism of action (OMA) drugs.

RESULTS

In the European sample of RA-BE-REAL, patients with RA treated with baricitinib experienced fewer discontinuations in comparison to those treated with tumour necrosis factor inhibitors or OMA. Overall, patients naïve to b/tsDMARDs achieved a higher rate of LDA and remission compared with experienced patients. A significantly greater proportion of patients treated with baricitinib achieved LDA compared with b/tsDMARDs.

CONCLUSION

This real-world data can better inform clinicians about baricitinib effectiveness and drug survival when prescribing treatment for patients with RA across different subpopulations.

Are We on the Same Page? A Cross-Sectional Study of Patient-Clinician Goal Concordance in Rheumatoid Arthritis

OBJECTIVE

Patient-clinician goal concordance is associated with improved outcomes in certain chronic diseases but not explored in rheumatoid arthritis (RA). We examined goal concordance, correlates of concordance, and the association of concordance with health outcomes.

METHODS

Adult patients with RA seen at least 1 time in the prior 12 months at 1 of 2 rheumatology clinics participated. Patients and their clinicians independently ranked top 3 goals for RA treatment from 8 options before a routine visit. Patients completed postvisit surveys on health, demographic information, health literacy, and adherence. Goal concordance was defined as the patient's number 1 goal being among the clinician's top 3 goals for that patient. Bivariable and multivariable logistic regression models were used to examine correlates of concordance.

RESULTS

Patients were 58% female and 16% Spanish-speaking, and 29% had limited health literacy. Among 204 patient-clinician dyads, 20% were goal-discordant. "Have less pain" was selected by both patient and clinician in 81% of dyads, followed by "have fewer problems doing daily activities" by 63%. Otherwise, clinicians prioritized avoiding side effects, whereas patients ranked improved sleep, fatigue, and mood. Longer disease duration was associated with discordance (median 13.3 years, interquartile range [IQR] 5.2-20 among discordant vs. 7 years, IQR 4-14; P = 0.039); higher depressive symptoms were associated with concordance (8.1% vs. 24%; P = 0.04). Goal concordance was associated with higher medication adherence (adjusted odds ratio 2.76 [95% confidence interval 1.01, 7.56]).

CONCLUSION

One in 5 patient-clinician dyads had discordant treatment goals. Goal concordance was associated with higher medication adherence. Studies to improve goal elicitation and communication of patients with RA's priorities are needed.

The RA-BE-REAL Multinational, Prospective, Observational Study in Patients with Rheumatoid Arthritis Receiving Baricitinib, Targeted Synthetic, or Biologic Disease-Modifying Therapies: a 6-Month Interim Analysis

INTRODUCTION

RA-BE-REAL has the overall aim of defining a profile of patients with rheumatoid arthritis (RA) starting baricitinib or any other targeted synthetic (ts) or any biologic (b) disease-modifying antirheumatic drug (DMARD) for the first time, and the primary objective of estimating time until discontinuation from any cause (excluding sustained response) of the initial treatment.

METHODS

RA-BE-REAL is an ongoing, prospective, observational, 36-month study in patients with RA initiating treatment with baricitinib (cohort A) or any other tsDMARD or any bDMARD (cohort B) for the first time. The primary objective is to assess the time until treatment discontinuation from any cause (excluding sustained response) at 24 months, (i.e., the rate of discontinuation of initial baricitinib or ts/bDMARD). Patient profiles of each cohort are described and compared. Post-baseline data are descriptively analyzed. This manuscript presents baseline and interim (6-month) outcomes for European patients with RA participating in the global RA-BE-REAL study.

RESULTS

Data from 1074 patients (cohort A: 509; cohort B: 565) were analyzed. For cohorts A and B, respectively, the 6-month cumulative incidence (95% confidence interval) of treatment discontinuation was 16.5 (12.9-21.1) and 23.3 (19.1-28.2), and the proportions of patients achieving remission were 25.6% and 18.5%. At baseline, mean patient age was 59.1 and 57.0 years (p = 0.010) and mean disease duration was 10.0 and 8.9 years (p = 0.047), respectively. The proportions of patients exposed to ts/bDMARDs at any time before study entry were 51.9% and 39.1%, and the proportions of patients initiated on monotherapy were 50.9% and 31.2%, respectively.

CONCLUSION

In real-world settings, patients with RA initiating treatment with baricitinib were older and had longer disease duration than those initiating treatment with any other tsDMARD or any bDMARD. Initial descriptive data regarding treatment discontinuation (including reasons for discontinuation), effectiveness, and treatment patterns will be enriched as the study progresses.

Validation of the Simplified Disease Activity Index (SDAI) with a quick quantitative C-reactive protein assay (SDAI-Q) in patients with rheumatoid arthritis: a prospective multicenter cross-sectional study

Objectives:

The Simplified Disease Activity Index (SDAI) is a recommended composite score for assessing the remission status in patients with rheumatoid arthritis (RA). However, determination of C-reactive protein (CRP) levels takes several hours and sometimes days and limits the use of the SDAI in the clinical setting. The aim of this study was to validate the SDAI using a quick quantitative C-reactive protein (qCRP) assay (as SDAI-Q) in RA patients.

Design:

This is a multicenter, prospective, cross-sectional pilot study in RA patients.

Methods:

Adult patients (⩾18 years) with a clinical diagnosis of RA were recruited between January 2020 and September 2020 from five rheumatologic centers located in Berlin, Germany. SDAI, SDAI-Q, Clinical Disease Activity Index (CDAI), and DAS28 scores comprising CRP, qCRP, or erythrocyte sedimentation rate (ESR) were calculated. The agreement of disease activity categories was analyzed using cross tabulations and weighted Cohen’s kappa. The agreement of numerical values was analyzed with Bland–Altman plots and intraclass correlation coefficients (ICCs).

Results:

Overall, 100 RA patients were included in the statistical analysis. The mean value of qCRP (7.89 ± 16.98 mg/l) was slightly higher than that of routine laboratory CRP (6.97 ± 15.02 mg/l). Comparing SDAI and SDAI-Q, all patients were assigned to identical disease activity categories. Agreement of disease activity categories by CDAI and SDAI/SDAI-Q was observed in 93% with a weighted Cohen’s kappa of 0.929 (95% confidence interval (CI) = 0.878; 0.981).

Conclusion:

The SDAI-Q showed an absolute agreement regarding the assignment of disease activity categories in comparison with the conventional SDAI. Therefore, the SDAI-Q may facilitate the application of a treat-to-target concept in clinical trials and clinical routine as a quickly available disease activity score incorporating CRP as an objective parameter.

Association between TNFi anti-drug antibodies, smoking, and disease activity in patients with inflammatory arthritis: Results from a Norwegian cross-sectional observational study

Introduction

We aimed to compare demographics and clinical characteristics between patients with inflammatory arthritis (IA) with vs. without neutralizing anti-drug antibodies (nADAb) against tumor necrosis factor inhibitors (TNFi). A secondary aim of the study was to explore if current smokers were more frequently nADAb-positive.

Methods

TNFi-treated outpatients with IA were recruited and a broad range of disease activity measures were assessed. nADAb were assessed using a reporter gene assay. Comparisons between nADAb-positive and -negative patients were done in unadjusted analyses as well as in adjusted logistic regression and general linear models.

Results

A total of 282 patients with IA currently under treatment with TNFi were included. nADAb were identified in 11 patients (nine treated with infliximab, one with etanercept and one with certolizumab pegol). Patients with nADAb reported significantly worse joint pain, patient’s global assessment, Health Assessment Questionnaire, Bath Ankylosing Spondylitis Disease Activity/Functional Index and Short-Form-36 physical functioning scale score than patients without nADAb (p < 0.04, adjusted analyses). 28-joint Disease Activity Score, Simplified Disease Activity Index and Maastricht Ankylosing Spondylitis Enthesitis score were also significantly worse in the nADAb-positive patients (p < 0.04, adjusted analyses), as were serum calprotectin, C-reactive protein and numbers of circulating peripheral leukocytes (p ≤ 0.001). A significantly higher proportion of nADAb-positive patients were current smokers (46 vs. 15%), in unadjusted as well as adjusted analyses (p ≤ 0.008).

Conclusions

nADAb-positive patients were more frequently smokers and had significantly worse disease activity, physical function, and inflammatory markers, than patients without nADAb. The association between smoking and nADAb positivity warrants further examination.

Sex difference in disease burden of inflammatory arthritis patients treated with tumor necrosis factor inhibitors as part of standard care

Objective

Knowledge is needed on the total disease burden across the sexes in inflammatory arthritis (IA). We aimed to compare disease burden, including a broad range of health aspects, across men and women with IA treated with tumor necrosis factor inhibitors (TNFi).

Methods

Adult outpatients with IA (rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis) were included as part of standard care. Patient-reported outcomes, disease activity, TNFi trough levels, calprotectin, Work Productivity and Activity Impairment, comorbidities and cardiovascular risk profile were assessed. Unadjusted comparisons across sexes were done with independent t-test, Mann-Whitney U-test and X²-test and adjusted analyses with General Linear Models and logistic/ordinal logistic regression.

Results

A total of 305 IA patients were included (167 men, 138 women). A significantly lower proportion of women (45%) than men (59%) were in remission according to disease-specific composite scores (p = 0.02). Women had significantly worse scores on pain, joint pain, fatigue, enthesitis, Health Assessment Questionnaire and Short Form (SF)-36 vitality and social functioning (all p≤0.04). Both sexes had worse SF-36 scale scores than the general population. Women reported more absenteeism (work time missed) and activity impairment. TNFi trough levels, neutralizing antibodies and calprotectin were similar across sexes. A similar total number of comorbidities was seen. Self-reported hypothyroidism was more frequent in women. Men had higher 10-year calculated risk of fatal cardiovascular events.

Conclusion

Important differences in disease burden between men and women were seen. More attention to sex differences in the follow-up of IA patients is warranted.

P4 Medicine as a model for precision periodontal care

Objectives

P4 Medicine is based on a proactive approach for clinical patient care incorporating the four “pillars” of prediction, prevention, personalization, and participation for patient management. The purpose of this review is to demonstrate how the concepts of P4 medicine can be incorporated into the management of periodontal diseases (particularly periodontitis) termed P4 periodontics.

Methods

This is a narrative review that used current literature to explore how P4 periodontics can be aligned with the 2018 Classification of Periodontal Diseases, current periodontal treatment paradigms, and periodontal regenerative technologies.

Results

The proposed model of P4 periodontics is highly aligned with the 2018 Classification of Periodontal Diseases and represents a logical extension of this classification into treatment paradigms. Each stage of periodontitis can be related to a holistic approach to clinical management. The role of “big data” in future P4 periodontics is discussed and the concepts of a treat-to-target focus for treatment outcomes are proposed as part of personalized periodontics. Personalized regenerative and rejuvenative periodontal therapies will refocus our thinking from risk management to regenerative solutions to manage the effects of disease and aging.

Conclusions

P4 Periodontics allows us to focus not only on early prevention and intervention but also allow for personalized late-stage reversal of the disease trajectory and the use of personalized regenerative procedures to reconstruct damaged tissues and restore them to health.

Clinical Significance

P4 Periodontics is a novel means of viewing a holistic, integrative, and proactive approach to periodontal treatment.

Prediction of flare following remission and treatment withdrawal in early rheumatoid arthritis: post hoc analysis of a phase IIIb trial with abatacept

Background

Drug-free remission is a desirable goal in rheumatoid arthritis (RA) for both patients and clinicians. The aim of this post hoc analysis was to investigate whether clinical and magnetic resonance imaging (MRI) variables in patients with early RA who achieved remission with methotrexate and/or abatacept at 12 months could predict disease flare following treatment withdrawal.

Methods

In the AVERT study of abatacept in early RA, patients with low disease activity at month 12 entered a 12-month period with all treatment discontinued (withdrawal, WD). This post hoc analysis assessed predictors of disease flare at WD+6months (mo) and WD+12mo of patients with Disease Activity Score in 28 joints (DAS28)-defined remission (DAS28[C-reactive protein (CRP)] <2.6) at withdrawal using univariate and multivariable regression models. Predictors investigated included the Health Assessment Questionnaire–Disability Index (HAQ-DI), pain, Patient Global Assessment; MRI synovitis, erosion, bone edema, and combined (synovitis + bone edema) inflammation scores.

Results

Remission was achieved by 172 patients; 100 (58%) and 113 (66%) patients had experienced a flare at WD+6mo and WD+12mo, respectively. In univariate analyses, higher HAQ-DI and MRI synovitis, erosion, bone edema, and combined inflammation scores at WD were identified as potential predictors of flare (P ≤ 0.01). In multivariable analysis, high scores at WD for HAQ-DI and MRI erosion were confirmed as independent predictors of flare at WD+6mo and WD+12mo (P < 0.01).

Conclusion

In patients with early RA achieving clinical remission, patient function (HAQ-DI), and MRI measures of bone damage (erosion) predicted disease flare 6 and 12 months after treatment withdrawal. These variables may help identify patients with early RA in clinical remission as candidates for successful treatment withdrawal.

Value of Literature Review to Inform Development and Use of Biologics in Juvenile Idiopathic Arthritis

BACKGROUND

Juvenile idiopathic arthritis (JIA) is one of the most common pediatric inflammatory rheumatic diseases (PiRDs). Uncontrolled disease activity is associated with decreased quality of life and chronic morbidity. Biologic disease-modifying antirheumatic drugs (bDMARDs) and Janus kinase inhibitors (JAKi) have considerably improved clinical outcomes. For optimized patient care, understanding the efficacy-safety profile of biologics in subgroups of JIA is crucial. This systematic review based on published randomized controlled trials (RCTs) aims to assess efficacy and safety data for bDMARDs and JAKi with various JIA subgroups after 3 months of treatment.

METHODS

Data for American College of Rheumatology (ACR) pediatric (Pedi) 30, 50, and/or 70 responses after 3 months of treatment were selected from RCTs investigating bDMARDs or JAKi in JIA according to predefined inclusion/exclusion criteria. Treatment and control arms were compared by calculating risk ratios (RRs) with 95% confidence intervals (CIs), and proportions of overall, serious adverse events (AEs) and infections were analyzed. Forest plots were generated to summarize efficacy and safety endpoints across studies, JIA subgroups, and type of biologics.

RESULTS

Twenty-eight out of 41 PiRD RCTs investigated bDMARD or JAKi treatments in JIA. 9 parallel RCTs reported ACR Pedi 30, 50, and/or 70 responses 3 months after treatment initiation. All treatment arms showed improved ACR Pedi responses over controls. RRs ranged from 1.05 to 3.73 in ACR Pedi 30, from 1.20 to 7.90 in ACR Pedi 50, and from 1.19 to 8.73 in ACR Pedi 70. An enhanced effect for ACR Pedi 70 was observed with infliximab combined with methotrexate in PJIA vs. methotrexate monotherapy. A slightly higher risk of gastrointestinal AEs and infections was observed with treatment arms compared to placebo or methotrexate monotherapy.

CONCLUSION

Investigated bDMARDs and JAKi showed superior treatment responses compared to controls after 3 months of treatment, which were more pronounced in ACR Pedi 50 and 70 than in ACR Pedi 30. Higher susceptibility to infections associated with bDMARDs or JAKi vs. control arms must be weighed against efficacious treatment of the underlying disease and prevention of disease-related damage. Additional RCTs are warranted to further inform development and utilization of biologics in JIA.

Early Improvements in Disease Activity Indices Predict Long-Term Clinical Remission Suggested by the Treat-to-Target Strategy in Patients with Ankylosing Spondylitis Receiving TNF-α Inhibitor Treatment

This study evaluated the possibility of clinical remission suggested by the treat-to-target strategy and identified predictors of clinical remission in 139 patients with ankylosing spondylitis (AS) receiving tumor necrosis factor-α inhibitors (TNFi). Clinical remission criteria selected were AS Disease Activity Score Inactive Disease (ASDAS-ID) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) < 2 with normal C-reactive protein (CRP) levels (BASDAI-CRP). The longitudinal relationship between clinical parameters and clinical remission was assessed using generalized estimating equations (GEEs). Responders to ASDAS-ID and BASDAI-CRP increased from 32.4% to 68.9% and from 39.9% to 75.2% at months 3 and 33, respectively. Responders to ASDAS-ID and BASDAI-CRP almost overlapped. In the univariable GEE model, age and 3-month improvement in BASDAI, ASDAS-CRP, physician and patient global assessments, and spinal pain predicted clinical remission achievement, while the presence of syndesmophytes predicted ASDAS-CRP achievement, and normalized CRP at 3 months was associated with BASDAI-CRP achievement. Multivariable GEE analysis revealed age (odds ratio (OR): 0.67; 95% confidence interval (CI), 0.49–0.93) and 3-month BASDAI improvement (OR: 1.70; CI, 1.19–2.41) as independent predictors of ASDAS-ID achievement and age (OR: 0.69; CI, 0.54–0.89), 3-month BASDAI improvement (OR: 2.00; CI, 1.45–2.76), and normalized CRP at 3 months (OR: 3.72; CI, 1.39–9.95) as independent predictors of BASDAI-CRP achievement.

Healthcare Costs of Not Achieving Remission in Patients with Rheumatoid Arthritis in the United States: A Retrospective Cohort Study

Introduction

To compare all-cause and rheumatoid arthritis (RA)-related healthcare costs and resource use in patients with RA who do not achieve remission versus those who achieve remission, using clinical practice data.

Methods

Data were derived from Optum electronic health records linked to claims from commercial and Medicare Advantage health plans. Two cohorts were created: remission and non-remission. Remission was defined as Disease Activity Score 28-joint count with the C-reactive protein level or erythrocyte sedimentation rate (DAS28-CRP/ESR) < 2.6 or Routine Assessment of Patient Index Data 3 (RAPID3 ≤ 3.0). Outcomes were all-cause and RA-related costs and resource use during a 1-year follow-up period. A weighted generalized linear regression and negative binomial regression were used to estimate adjusted annual costs and resource use, respectively, controlling for confounding factors, including patient and socio-demographic characteristics.

Results

Data from 335 patients (remission: 125; non-remission: 210) were analyzed. Annual all-cause total costs were significantly less in the remission versus non-remission cohort ($30,427 vs. $38,645, respectively; cost ratio [CR] = 0.79; 95% CI 0.63, 0.99). All-cause resource use (mean number of visits) was less in the remission versus non-remission cohort: inpatient (0.23 vs. 0.63; visit ratio [VR] = 0.36; 95% CI 0.19, 0.70), emergency department (0.36 vs. 0.77; VR = 0.47; 95% CI 0.30, 0.74), and outpatient visits (20.7 vs. 28.5; VR = 0.73; 95% CI 0.62, 0.86). Annual RA-related total costs were similar in both cohorts; however, RA-related medical costs were numerically lower in the remission versus non-remission cohort ($8,594 vs. $10,002, respectively; CR = 0.86; 95% CI 0.59, 1.25). RA-related resource use was less in the remission versus non-remission cohort.

Conclusions

Significant economic burden was associated with patients who did not achieve remission compared with those who did achieve remission.

Disease impact of rheumatoid arthritis in patients not treated with advanced therapies; survey findings from the National Rheumatoid Arthritis Society

Objective

The aim was to reveal the everyday impact of living with RA in people not treated with advanced therapies (i.e. biologic or targeted synthetic DMARDs).

Methods

People with RA, with disease duration >2 years, not currently treated with advanced therapies, completed an online survey promoted by the National Rheumatoid Arthritis Society. Items covered demographics, current treatment, RA flare frequency, the Rheumatoid Arthritis Impact of Disease (RAID) tool and questions reflecting work status and ability. Descriptive and multivariable regression analyses were performed.

Results

There were 612 responses from patients having a mean age of 59 years, 88% female, 37.7% with disease duration 2–5 years and 27.9% with disease duration 5–10 years. In the last year, 90% reported an RA flare, with more than six flares in 23%. A RAID patient acceptable state was recorded in 12.4%. Each of the seven domains was scored in the high range by >50% respondents; 74.3% scored sleep problems and 72% fatigue in the high range. A need to change working hours was reported by 70%. Multivariable analyses revealed that increasing difficulties with daily physical activities, reduced emotional and physical well-being in the past week were all significantly associated with pain, number of flares and ability to cope (P < 0.005). The RAID score was significantly predictive of the number of flares.

Conclusion

Patients not currently treated with advanced therapies experience profound difficulties in everyday living with RA, across a broad range of measures. We advocate that patient-reported measures be used to facilitate holistic care, addressing inflammation and other consequences of RA on everyday life.

Factors associated with achieving target serum uric acid level and occurrence of gouty arthritis: A retrospective observational study of Japanese health insurance claims data

Purpose

This study assessed factors associated with achieving target serum uric acid (sUA) level and occurrence of gouty arthritis in Japanese clinical practice.

Methods

Japanese health insurance claims and medical check‐up data from October 2015 to March 2017 were analyzed to assess factors associated with target sUA achievement in gout and asymptomatic hyperuricemia and gouty arthritis in gout. Target sUA was further assessed by subgroup analysis of urate‐lowering therapy (ULT) prescriptions and outcomes, stratified by renal function.

Results

Patients achieving target sUA tended toward older, female, higher ULT dose, higher adherence, more comorbidities, and/or antidiabetic drugs prescribed. Renal dysfunction and/or diuretic prescriptions were associated with reduced achievement of target sUA. Severe renal dysfunction was particularly influential (odds ratio [OR] = 0.22 [95% confidence interval (CI): 0.10‐0.48] for <15, 0.15 [0.10‐0.23] for ≥15 to <30, compared with eGFR ≥90 mL/min/1.73 m²). Across all renal function categories, mean prescribed ULT dose was low (febuxostat 17.0‐21.0 mg/day, allopurinol 123.1‐139.6 mg/day), and target sUA achievement was reduced among renal dysfunction patients. Gouty arthritis was more likely in patients with a prior history of such occurrences, and less likely for higher ULT adherence, sUA monitored regularly at medical facilities, and/or more comorbidities.

Conclusion

In a real‐world setting, severe renal dysfunction is the most important risk factor for failure to achieve the target sUA, suggesting suboptimal disease management in patients with gout or hyperuricemia complicated by this condition. Findings associated with gouty arthritis suggest that these occurrences could be successfully managed by regular monitoring of sUA and closer adherence to ULT.

Outcomes in patient education programmes for people with rheumatic diseases: Results from a Delphi process and a study of feasibility and responsiveness

BACKGROUND

Patient education (PE) is recommended as an integral part of disease management for people with chronic inflammatory arthritis (IA). There is no consensus on how PE should be evaluated and which outcome measures should be used.

OBJECTIVES

This study had three aims: (a) to identify core aspects that PE for patients with IA may impact on; (b) to identify outcome measures to assess changes in these aspects; (c) to test the feasibility and responsiveness of the identified outcome measures.

METHODS

A Delphi process was conducted to identify core aspects and outcome measures. Feasibility and responsiveness were tested in a pre-/post-test study with 3 months follow-up, including 104 patients attending PE programmes.

RESULTS

Seven core aspects were identified: communication with health professionals, coping strategies, empowerment, knowledge about healthy life style, self-efficacy, understanding disease and treatment, and sharing experiences. Four outcome measures were identified; Arthritis Self Efficacy Scale (ASES-11), Effective Consumer scale (EC-17), Health Education Impact Questionnaire (heiQ) and Patient Activation Measure (PAM). At baseline, all measures had low rates of missing data. All measures except two heiQ subscales exhibited ceiling effects. Internal consistency was acceptable. At follow-up, statistically significant, but small improvements were found in EC-17 and three heiQ subscales.

CONCLUSION

ASES and EC-17 were found to be the most valid and feasible outcome measures to evaluate the identified core aspects of PE and can be recommended as outcome measures to assess PE programmes for patients with IA.

Innately Adaptive or Truly Autoimmune: Is There Something Unique About Systemic Juvenile Idiopathic Arthritis?

Systemic juvenile idiopathic arthritis (JIA) is a form of arthritis in childhood that is initially dominated by innate immunity-driven systemic inflammation and is thus considered a polygenic autoinflammatory disease. However, systemic JIA can progress toward an adaptive immunity-driven afebrile arthritis. Based on this observation of biphasic disease progression, a "window of opportunity" for optimal, individualized and target-directed treatment has been proposed. This hypothesis requires testing, and in this review we summarize current evidence regarding molecular factors that may contribute to the progression from an initially predominantly autoinflammatory disease phenotype to autoimmune arthritis. We consider the involvement of innately adaptive γδ T cells and natural killer T cells that express γδ or αβ T cell receptors but cannot be classified as either purely innate or adaptive cells, versus classic B and T lymphocytes in this continuum. Finally, we discuss our understanding of how and why some primarily autoinflammatory conditions can progress toward autoimmune-mediated disorders over the disease course while others do not and how this knowledge may be used to offer individualized treatment.

Health status and self-management in patients with inflammatory arthritis-A five-year follow-up study after nurse-led patient education

Aim

The aim of this study was to investigate changes in patients' self-management and health status five years after nurse-led patient education.

Design

A longitudinal study.

Methods

We collected self-reported data on physical function, pain, tiredness, disease activity, psychological status, patient activation and self-efficacy from a sample of Norwegian-speaking adults with inflammatory arthritis that had participated in a randomised controlled study investigating the effects of nurse-led patient education. Changes and associations in patients' health status and self-management were analysed with paired sample t tests and multivariable linear regression analyses, respectively.

Results

Except from a small deterioration in patients' physical function, there were no changes in patients' health status 5 years after the nurse-led patient education. Patients' self-management skills were improved after 5 years. Self-efficacy was positively associated with female gender, patient activation, less tiredness and less psychological distress.

Abatacept retention and clinical outcomes in Austrian patients with rheumatoid arthritis: real-world data from the 2-year ACTION study

BACKGROUND

AbataCepT In rOutiNe clinical practice (ACTION; NCT02109666) was a 2-year international observational study of patients with moderate to severe rheumatoid arthritis.

METHODS

Baseline characteristics, abatacept retention rates, and clinical outcomes were compared by treatment line in the Austrian cohort of ACTION.

RESULTS

Of 100 patients enrolled in Austria, 98 (98.0%) were evaluable: 33/98 (33.7%) biologic naïve and 65/98 (66.3%) with ≥1 prior biologic failure. At baseline, biologic-naïve patients had shorter disease duration and lower concomitant corticosteroid use than biologic-failure patients. Overall crude abatacept retention rate was 60.5% and retention rate was higher in biologic-naïve (65.1%) versus biologic-failure (58.0%) patients. Good/moderate EULAR (European League Against Rheumatism) response rates were 85.7% in biologic-naïve and 100% in biologic-failure patients.

CONCLUSIONS

In the Austrian cohort of ACTION, overall abatacept retention at 2 years was high, with higher retention rates in patients receiving abatacept as an earlier treatment line. Good/moderate EULAR response rate was higher in biologic-failure than in biologic-naïve patients.

Determining MRI Inflammation Targets When Considering a Rheumatoid Arthritis Treat-to-Target Strategy: Results of a Randomized, Placebo-Controlled Trial

Introduction

Magnetic resonance imaging (MRI) is increasingly used in patients with rheumatoid arthritis (RA) to determine residual inflammation after treatment and as a predictor of structural damage progression. Establishing an optimal threshold of inflammatory activity that predicts lower risk of structural damage progression may inform treatment decisions. This post hoc analysis investigated whether patients with RA at low risk of structural damage progression can be identified based on MRI inflammation thresholds.

Methods

Hand and wrist MRI was performed at baseline, and at months 6 and 12 in a phase 3b, randomized, active-controlled, double-blind trial of abatacept in early RA (AVERT). Pathologies were scored using the OMERACT RA MRI Score. Data were stratified into two risk subgroups (less and more severe inflammation) for structural damage progression (erosion change > 0.5) based on baseline inflammation. In this post hoc analysis, log odds ratios of probability of progression {adjusted for baseline Disease Activity Score in 28 joints [C-reactive protein; DAS28 (CRP)]} were compared between subgroups to test the performance of inflammation thresholds.

Results

There were 351 randomized and treated patients with baseline MRIs, of whom 276 (78.6%) and 235 (67.0%) had MRIs available at months 6 and 12, respectively. The DAS28 (CRP)-adjusted probabilities of progression from baseline to month 12 based on scores at baseline, and from months 6 to 12 based on month 6 scores, were significantly lower among patients with less inflammation (P < 0.0001–0.0459), independent of clinical disease activity. Predefined thresholds of synovitis ≤ 3 (total score 21), osteitis ≤ 3 (total score 69) and total inflammation score (osteitis double-weighted) ≤ 9 were associated with a lower likelihood of structural damage progression in unadjusted analyses.

Conclusion

Levels of MRI-determined inflammatory activity below defined thresholds were independently associated with a lower risk of structural damage progression in early RA, providing a potential trial endpoint for levels of inflammation not associated with progression.

Defining the target: clinical aims in axial spondyloarthritis

Treat-to-target (T2T) is an emerging treatment paradigm in axial spondyloarthritis (axSpA), originally based on evidence from other inflammatory conditions, which aims to direct therapy to a clear target such as disease remission or low disease activity, with the ultimate goal of maximizing quality of life in affected individuals. The 2016 update of the Assessment of Spondyloarthritis International Society/EULAR guidelines for axSpA have recommended that treatment should be guided according to a predefined target but controversy remains as to what this target should be. An international task force has recommended remission or inactive disease as the desired outcome; however, there are many disease outcome measures developed for use in clinical practice in axSpA and the question remains of which is the most appropriate to use. Another important consideration when discussing the T2T paradigm is when to intervene. Although evidence is limited in this respect, the available data suggest that therapy should be commenced at an early stage of the disease, when the process of bone repair expected to occur after an inflammatory phase has not yet started. It has also been argued that the success of the T2T paradigm may depend more on the treatment strategy than the individual therapies utilized. This article will explore the feasibility of using a T2T approach in axSpA clinical practice, the utilization of new composite outcome measures of disease activity such as the ASDAS, and the validity of different treatment strategies to allow for a T2T intervention in these patients.

Abatacept retention and clinical outcomes in rheumatoid arthritis: real-world data from the German cohort of the ACTION study and a comparison with other participating countries

INTRODUCTION

AbataCepT In rOutiNe clinical practice (ACTION; NCT02109666) was an observational study of patients with rheumatoid arthritis who initiated intravenous abatacept in clinical practice. We aimed to compare abatacept retention rates and clinical outcomes in patients from Germany versus other countries.

METHOD

Baseline characteristics, crude retention rates, and clinical outcomes were compared by treatment line in the German cohort at 2 years. In addition, biologic-naïve patients were compared with biologic-naïve patients pooled from other participating countries.

RESULTS

In the German cohort, 677/680 (99.6%) patients enrolled were evaluable and 171/677 (25.3%) were biologic naïve. At baseline, abatacept monotherapy was received by a similar proportion of biologic-naïve and biologic-failure patients in the German cohort, but by a greater proportion of biologic-naïve patients in German versus other countries cohort (27.5 vs. 12.9%). The overall crude abatacept retention rate at 2 years in the German cohort was 39.9%; retention rate did not differ significantly by treatment line, but among biologic-naïve patients it was lower in Germany than in the other countries cohort (42.1 vs. 58.7%; log-rank test p < 0.001). At 2 years, good/moderate European League Against Rheumatism (EULAR) response rates in biologic-naïve patients were 85.5% in the German and 92.1% in other countries cohort (p = 0.163).

CONCLUSIONS

In the German cohort of ACTION, abatacept retention at 2 years was similar in biologic-naïve and biologic-failure patients. Biologic-naïve patients in German cohort had a significantly lower abatacept retention rate and a trend of lower good/moderate EULAR response rate than those in the other countries cohort.

KEY POINTS

• Analyses of data from national patient cohorts provide insight on local treatment patterns. • In the German cohort of the ACTION study, abatacept retention at 2 years was similar in biologic-naïve and biologic-failure patients. • Biologic-naïve patients from the German cohort had a significantly lower abatacept retention rate and a trend of lower good/moderate EULAR response rate than patients from other countries. • Data from large international studies may not be directly applicable to individual countries.

Evaluation of Proposed Criteria for Remission and Evidence-Based Development of Criteria for Complete Response in Patients With Chronic Refractory Gout

Objective

The objective of this study is to assess criteria for gout remission and to use the results to inform criteria for a complete response (CR).

Methods

A post hoc analysis of two clinical trials was undertaken to determine the frequency with which subjects with chronic refractory gout who were treated with pegloticase met remission criteria. Mixed modeling was then employed to identify the components that best correlated with time to maximum benefit.

Results

Of the 56 subjects treated with biweekly pegloticase for whom adequate data were collected, 48.2% met the remission criteria. When subjects with persistent lowering of urate levels were examined separately, 27 of 32 (84.4%) met the criteria for remission. In contrast, even when the requirement for lowering of serum urate levels was waived, only 2 of 24 (8.3%) subjects without persistent lowering of urate levels and 0 of 43 subjects receiving placebo met criteria. Mixed modeling indicated that in addition to urate levels, assessment of tophi, swollen joints, and tender joints and patient global assessment best correlated with time to maximum benefit. Using these criteria of CR, 23 of the responders (71.9%) met the criteria. All patients who achieved a CR maintained it for a mean duration of 507.4 days. Finally, 64% of persistent responders to monthly pegloticase also met criteria for CR.

Conclusion

These results have validated the proposed remission criteria for gout and have helped define criteria for CR in individuals with chronic gout treated with pegloticase. This composite CR index can serve as an evidence-based target to inform the design and end points of future clinical trials.

Janus kinase inhibitors in immuno-inflammatory rheumatic diseases: new opportunities and prospects

Despite the great success in the diagnosis and treatment of immuno-inflammatory rheumatic diseases (IIRD), which led to a significant improvement in the prognosis in many patients, the fundamental medical problems of this pathology – the restoration of quality of life and reduction of mortality to the population level – are far from solution. This served as a powerful impetus to the study of new approaches to pharmacotherapy of IIRD, one of which is associated with the use of low-molecular synthetic drugs that inhibit intracellular "signal" molecules-Janus kinase (JAK), the socalled Jakinibs. The current achievements and trends concerning the use of JAK inhibitors in the treatment of IIRD are considered.

Remission in psoriatic arthritis-where are we now?

Advances in treatments and treatment strategies for PsA have led to many patients responding well to management of their disease, and targeting remission as a treatment goal is now a possibility. Treat to target is a strategy aimed at maximizing benefit, irrespective of the type of medication used, by monitoring disease activity and using it to guide therapy. The measurement of response to treatment has been the subject of wide discussions among experts for some time, and many instruments exist. Comparisons of the different measures and their different strengths and weaknesses is ongoing. The impact of modern imaging techniques on monitoring disease progression is also evolving, and advanced techniques using both MRI and US have the potential to improve management of PsA through identification of risk factors for poor prognosis as well as accurate assessment of inflammation and damage, including subclinical disease. Increased understanding of the pathways that drive the pathogenesis of PsA will be key to identifying specific biomarkers for the disease and developing effective treatment strategies. Targets for response, considerations for use of a treat to target strategy in PsA, different imaging techniques and serological aspects of remission are all discussed in this review, and areas for further research are identified.

Ten years of follow-up data in psoriatic arthritis: results based on standardized monitoring of patients in an ordinary outpatient clinic in southern Norway

BACKGROUND

Over the last decade, a treat-to-target (T2T) strategy has been recommended for psoriatic arthritis (PsA) and new treatment options have become available. There is a lack of data on PsA regarding any changes that may have occurred over these past years. Thus, the main aim of this study was to look for changes in clinical disease status and treatment in a PsA outpatient clinic population monitored over the period 2008 to 2017.

METHODS

Annual data collection included demographic data, laboratory (erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)) and clinic measures of disease activity (e.g., 28 and 32 joint count Disease Activity Score (DAS28), Clinical Disease Activity Index (CDAI), and modified Disease Activity index for Psoriatic arthritis (DAPSA)), evaluator's global assessment, and patient-reported outcomes (PROs), including for example measures of physical function, pain, and patient global assessment. Disease-modifying antirheumatic drug (DMARD) use was also registered.

RESULTS

In the PsA outpatient clinic population over the 10-year period (annual mean number of patients, 331) the mean (standard deviation) age was 58.4 (12.4) years, disease duration was 9.6 (7.9) years, 49.4% were female, and 17.6% were current smokers. From 2008 to 2017, no statistically significant increase in remission rates was seen for DAPSA (13.5% and 22.0%) or Boolean remission (6.6% and 8.9%), whereas a statistically significant increase was seen for DAS28-ESR (36.8% and 50.6%) and CDAI (20.0% and 29.6%), but not for the last 5 years (DAS28-ESR, 42.3% and 50.6%; CDAI, 27.9% and 29.6%). Furthermore, over the 10-year period no significant improvement for PROs and no significant change in the use of synthetic (annual mean 53.0%) and biologic DMARDs (annual mean 29.9%) was found.

CONCLUSION

Our data suggest that even in the biologic treatment era there is an unmet need for treating PsA patients to target remission. New treatment options and the development of more feasible and valid outcome measures for use in a T2T strategy in ordinary clinical practice may in the future to further improve clinical outcomes in PsA.

Spanish consensus on treat to target for osteoporosis

To reach a Spanish expert consensus on a treat-to-target strategy in osteoporosis, a Delphi Consensus Study has been developed. Most of the experts (59.8%) were rheumatologist with a mean clinical experience of 21.3 years (SD 8.5). Consensus was achieved for 70% of the items. Therapeutic objectives, patient follow-up scheme, treatment failure criteria, and appropriate treatment choice for use in T2T strategy in Spain have been defined.

INTRODUCTION

The paper aims to achieve a Spanish expert consensus on a treat-to-target (T2T) strategy in osteoporosis.

METHODS

A scientific committee led the project and was involved in expert panel identification and Delphi questionnaire development. Two Delphi rounds were completed. The first-round questionnaire included 24 items and assessed, using a seven-point Likert scale, the experts' wish (W) and prognosis (P) in 5 years for each topic (applicability, therapeutic objectives, patient follow-up, and possible treatment to be prescribed). Items for which there was no consensus in the first round were included in the second round. Consensus was defined as ≥75% agreement (somewhat/mostly/entirely agree) or disagreement (somewhat/mostly/entirely disagree) responses.

RESULTS

Of the experts, 112 and 106 completed the first and second rounds, respectively. 59.8% were rheumatologists with a mean clinical experience of 21.3 years (SD 8.5). Consensus was achieved for 70% of the items, and was established regarding the utility of a T2T strategy to define therapeutic objectives, optimal follow-up, and therapeutic algorithm. Participants agreed on the utility of the bone mineral density (BMD) value (T-score >-2.5 SD for spine and >-2.5/-2.0 SD for femoral neck), lack of fractures, and fracture risk (FRAX) as therapeutic objectives. For measuring BMD changes, consensus was achieved on the suitability of hip and femoral neck locations. Experts agreed to consider treatment failure as when a significant BMD gain could not be achieved, or when a new fracture occurs within 2-3 years. There was consensus that all proposed therapies should achieve a therapeutic target through T2T strategy (treatments with the highest consensus scores were denosumab and teriparatide).

CONCLUSION

The therapeutic objectives, patient follow-up scheme, treatment failure criteria, and appropriate treatment choice for use in T2T strategy in Spain have been established by a panel of experts. Some aspects nevertheless still require further analysis.

Factors influencing the use of biologic therapy and adoption of treat-to-target recommendations in current European rheumatology practice

OBJECTIVE

The aim of this study was to identify factors that influence treatment adjustments and adoption of a treat-to-target (T2T) strategy in patients with rheumatoid arthritis (RA) in European practices.

METHODS

Cross-sectional data were drawn from the Adelphi 2014 RA Disease Specific Programme. Treatment patterns and clinical characteristics were investigated in patients treated with biologic disease-modifying antirheumatic drugs (bDMARDs) vs non-bDMARDs. For the T2T analysis, patients were subdivided into two subsets (RA diagnosis <2 or ≥2 years) and compared according to the approach used (no target = no T2T approach; pragmatic = target different from remission; and aspirational = target set as remission).

RESULTS

Data from 2,536 patients were analyzed (mean age: 52.76 years and mean time since RA diagnosis: 6.05 years). Of the 1,438 patients eligible to receive bDMARDs, 55% did not receive them. Initiation of bDMARDs in a bDMARD-naïve patient was prompted by worsening of the disease. In the RA diagnosis <2 years subset, a T2T approach was not adopted in 58% of the patients, whereas 8% and 34% adopted a pragmatic and aspirational approach, respectively. In the RA diagnosis ≥2 years subset, 45%, 19%, and 36% of the patients adopted a no target, pragmatic, and aspirational approach, respectively. Physician satisfaction with RA control was lower in the RA diagnosis <2 years subset than in the RA diagnosis ≥2 years subset (65% vs 77% satisfied, respectively; P<0.0001).

CONCLUSION

This analysis shows that the use of bDMARDs remains suboptimal and that a T2T strategy is not universally adopted.

Therapeutic Targets for Multiple Sclerosis: Current Treatment Goals and Future Directions

Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system, and the most common cause of nontraumatic disability in young adults. Most patients have a relapsing-remitting course, and roughly half of them will eventually enter a degenerative progressive phase, marked by gradual accrual of disability over time in the absence of relapses. Early initiation of treatment has delayed the onset of disability progression. Thus, there is increased interest in treating to target in MS, particularly targeting no evidence of disease activity. This review will describe the most common treatment goals in MS: the Rio scores, disease-free survival, and no evidence of disease activity. We will also cover how well current disease-modifying therapies achieve no evidence of disease activity, and discuss future options for improving MS treatment targets.

Effect of cardiorespiratory and strength exercises on disease activity in patients with inflammatory rheumatic diseases: a systematic review and meta-analysis

OBJECTIVE

To investigate the effects of cardiorespiratory and strength exercises on disease activity for patients with inflammatory rheumatic diseases (IRDs).

DESIGN

A systematic review with meta-analysis registered at PROSPERO (CRD42015020004).

PARTICIPANTS

Patients with IRDs.

DATA SOURCES

The databases MEDLINE, AMED, Embase and CINAHL were searched from inception up to April 2016.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Trials were included if they were randomised controlled trials of adults with IRDs, comparing the effect of cardiorespiratory and strength exercises with usual care on disease activity and followed the American College of Sports Medicine's exercise recommendations. The primary outcome was disease activity in terms of inflammation, joint damage and symptoms.

DATA SYNTHESIS

Data were pooled in a random-effect model for all outcomes, and standardised mean differences (SMDs) were calculated. The quality of evidence was evaluated according to the Grading of Recommendations Assessment, Development and Evaluation approach.

RESULTS

Twenty-six trials with a total of 1286 participants were included. There was high to moderate quality evidence, for a small beneficial effect on disease activity scores (0.19 (95% CI 0.05 to 0.33), p<0.01) and joint damage (SMD 0.27 (95% CI 0.07 to 0.46), p<0.01). Furthermore, moderate quality evidence for a small beneficial effect on erythrocyte sedimentation rate (SMD 0.20 (95% CI 0.0 to 0.39), p=0.04) and for no effect on C reactive protein (SMD -0.14 (95% CI -0.37 to 0.08), p=0.21). Beneficial effects were also seen for symptoms.

CONCLUSIONS

The results of this review suggest beneficial effects of exercises on inflammation, joint damage and symptoms in patients with IRDs.

High Disease Activity May Increase Fear-Avoidance Beliefs in Rheumatoid Arthritis

Objectives

This study aims to compare fear-avoidance (FA) beliefs of rheumatoid arthritis (RA) patients with osteoarthritis (OA) of hand patients and fibromyalgia (FM) patients and evaluate its relationship with RA activity and duration.

Patients and methods

The study included 206 patients with RA (34 males, 172 females; mean age 49 years; range 20 to 72 years), 57 patients with FM (57 females; mean age 48 years; range 20 to 71 years), and 50 patients with OA of hand (4 males, 46 females; mean age 43 years; range 43 to 77 years). FA beliefs were assessed with modified Fear-Avoidance Belief Questionnaire (mFABQ). RA patients were dichotomized according to disease activity and disease duration separately; cutoff values were disease activity score 28 of 3.2 and six months of disease activity, respectively.

Results

Modified Fear-Avoidance Belief Questionnaire scores were similar in patients with RA, OA of hand, and FM. RA patients in non-remission group had higher mFABQ scores. Moreover, mFABQ scores were similar in RA patients with early and established disease groups.

Conclusion

Fear-avoidance beliefs of patients with RA were similar with OA of hand patients and FM patients. However, higher disease activity in RA was related with escalated FA beliefs. Further studies focusing on pathophysiology of FA beliefs in patients with RA are warranted for effective pain management of RA.

Barriers and facilitators to disease-modifying antirheumatic drug use in patients with inflammatory rheumatic diseases: a qualitative theory-based study

Background

Although disease-modifying anti-rheumatic drugs (DMARDs) are the cornerstone of treatment for inflammatory rheumatic diseases, medication adherence to DMARDs is often suboptimal. Effective interventions to improve adherence to DMARDs are lacking, and new targets are needed to improve adherence. The aim of the present study was to explore patients’ barriers and facilitators of optimal DMARD use. These factors might be used as targets for adherence interventions.

Methods

In a mixed method study design, patients (n = 120) with inflammatory arthritis (IA) completed a questionnaire based on an existing adapted Theoretical Domains Framework (TDF) to identify facilitators and barriers of DMARD use. A subgroup of these patients (n = 21) participated in focus groups to provide insights into their facilitators and barriers. The answers to the questionnaires and responses of the focus groups were thematically coded by three researchers independently and subsequently categorized.

Results

The barriers and facilitators that were reported by IA patients presented large inter-individual variations. The identified barriers and facilitators could be captured in the following domains based on an adapted TDF: (i) knowledge, (ii) emotions, (iii) attention, memory, and decision processes, (iv) social influences, (v) beliefs about capability, (vi) beliefs about consequences, (vii) motivation and goals, (viii) goal conflict, (ix) environmental context and resources, and (x) skills.

Conclusions

Patients with IA have a variety of barriers and facilitators with regard to their DMARD use. All of these barriers and facilitators could be categorized into adapted domains of the TDF. Interventions that address individual facilitators and barriers, based on capability, opportunity, and motivation, are needed to develop strategies for medication adherence that are tailored to individual patient needs.
