Improving the Management of Psoriatic Arthritis and Axial Spondyloarthritis: Roundtable Discussions with Healthcare Professionals and Patients

Cardiovascular Risk Evaluation in Psoriatic Arthritis by Aortic Stiffness and the Systemic Coronary Risk Evaluation (SCORE): Results of the Prospective PSOCARD Cohort Study

INTRODUCTION

Psoriatic arthritis (PsA) is associated with increased cardiovascular (CV) risk and mortality. Aortic stiffness measured by carotid-femoral pulse wave velocity (cfPWV) has been shown to predict CV risk in the general population. The present study aimed to examine cfPWV values of patients with PsA compared to healthy controls and to evaluate associations of cfPWV with patient- and disease-associated characteristics, as well as with an established traditional CV prediction score of the European Society of Cardiology (Systemic Coronary Risk Evaluation; SCORE), for the first time.

METHODS

cfPWV and SCORE were evaluated in patients with PsA and healthy controls, along with clinical and laboratory disease parameters. Differences in cfPWV measurements between the two groups and associations of cfPWV with patient- and disease-associated characteristics were statistically evaluated.

RESULTS

A total of 150 patients with PsA (PSOCARD cohort) and 88 control subjects were recruited. cfPWV was significantly higher in the PsA group compared to controls, even after adjustment for confounders (padj = 0.034). Moreover, cfPWV was independently associated with disease duration (r = 0.304, p = 0.001), age (rho = 0.688, p < 0.001), systolic arterial pressure (rho = 0.351, p < 0.001), glomerular filtration rate (inverse: rho = - 0.264, p = 0.001), and red cell distribution width, a marker of major adverse CV events (MACE) (rho = 0.190, p = 0.02). SCORE revealed an elevated CV risk in 8.73% of the patients, whereas cfPWV showed increased aortic stiffness and end-organ disease in 16.00% of the same cohort.

CONCLUSIONS

In the largest cfPWV/PsA cohort examined to date, patients with PsA exhibited increased aortic stiffness compared to healthy controls. PsA duration was the most important independent disease-associated predictor of increased aortic stiffness, next to traditional CV risk factors. cfPWV measurements may help identify subclinical end-organ disease and abnormal aortic stiffness and thus assist CV risk classification in PsA.

Elevating the Standard of Care for Patients with Psoriatic Arthritis: 'Calls to Action' from a Multistakeholder Pan-European Initiative

INTRODUCTION

Psoriatic arthritis (PsA) is a complex, progressive, and often debilitating disease. Despite recent advances in treatment, numerous unmet needs in patient care persist. Rheumacensus is a multistakeholder, pan-European initiative designed to identify ways to elevate the standard of care (SoC) and treatment ambition for patients with PsA, using the perspectives of three key stakeholder groups: patients, healthcare professionals (HCPs) and payors.

METHODS

Rheumacensus followed three phases: an insights-gathering workshop to identify current unmet needs in PsA and an area of focus for the project, a modified Delphi process to gain consensus on improvements within the agreed area of focus, and a Consensus Council (CC) meeting which used consensus statements as inspiration to generate 'Calls to Action' (CTA)-practical measures which, if implemented, could elevate the SoC for patients with PsA.

RESULTS

The Rheumacensus CC consisted of four patient representatives, four HCPs and four payors. All 12 members completed all three Delphi e-consultations. The shared area of focus that informed the Delphi process was "patient empowerment through education on the disease and treatment options available, to enable patient involvement in management". Four key themes emerged from the Delphi process: patient empowerment, patient knowledge and sources of education, patient-HCP consultations, and optimal initial treatment. Statements within these themes informed 12 overarching CTA, which focus on the need for a multistakeholder approach to implementing a paradigm shift towards patient-centred care and improved outcomes for patients with PsA.

CONCLUSION

Rheumacensus has identified shortcomings in the current SoC for patients with PsA and provides a foundation for change through practical CTA. It is hoped that all stakeholders will now take practical steps towards implementing these CTA across Europe to elevate the SoC for patients with PsA.

Elevating the Standard of Care for Patients with Axial Spondyloarthritis: 'Calls to Action' from Rheumacensus, a Multistakeholder Pan-European Initiative

INTRODUCTION

Several barriers to optimal care in axial spondyloarthritis (axSpA) exist, which is detrimental to patient outcomes. The Rheumacensus programme aimed to identify how the standard of care (SoC) and treatment ambition for patients with axSpA could be elevated, from the unique perspective of three key stakeholders from across Europe: patients, healthcare professionals (HCPs) and payors.

METHODS

Rheumacensus followed three phases: an insights-gathering workshop to identify current unmet needs in axSpA and an area of focus, a modified Delphi process to gain consensus on improvements within the agreed area of focus, and a Consensus Council (CC) meeting to generate 'Calls to Action' (CTA) to highlight the changes needed to elevate the SoC for patients with axSpA.

RESULTS

The Rheumacensus CC consisted of four patient representatives, four HCPs and four payors. All 12 members completed all three Delphi e-consultations. The shared area of focus that informed the Delphi process was patient empowerment through education on the disease and treatment options available, to enable patient involvement in management and ultimately increase treatment adherence. Four key themes emerged from the Delphi process: patient empowerment, patient knowledge, patient-HCP consultations and optimal initial treatment. These themes informed 11 overarching CTA, which demonstrate the need for a multistakeholder approach to implement a paradigm shift towards patient-centred care to elevate health outcomes in patients with axSpA.

CONCLUSION

Rheumacensus identified CTA to help bridge the disparities observed in axSpA care. It is now imperative for all stakeholders to take practical steps towards addressing these CTA to elevate the SoC and treatment ambition in patients with axSpA.

Time to improvement of pain, morning stiffness, fatigue, and disease activity in patients with ankylosing spondylitis treated with tofacitinib: a post hoc analysis

BACKGROUND

Tofacitinib is an oral Janus kinase inhibitor for treatment of ankylosing spondylitis (AS). Time to improvement in core domains of AS was estimated in tofacitinib-treated patients with AS.

METHODS

This post hoc analysis used phase 3 trial data from patients with AS receiving tofacitinib 5 mg twice daily or placebo to week (W)16; all patients received open-label tofacitinib W16-48.

OUTCOMES

nocturnal pain; total back pain; fatigue, spinal pain, peripheral joint pain/swelling, enthesitis, and morning stiffness (Bath AS Disease Activity Index [BASDAI] questions 1-6); BASDAI total score; AS Disease Activity Score (ASDAS). Median time to improvement events was estimated using non-parametric Kaplan-Meier models. Improvement events were defined as initial (first post-baseline observation) and continued (sustained for 2 consecutive visits) ≥ 30% and ≥ 50% improvement in back/nocturnal pain or BASDAI questions/total scores, or ASDAS improvement ≥ 1.1 and ≥ 2.0 points.

RESULTS

269 patients (tofacitinib: n = 133; placebo-to-tofacitinib: n = 136) were assessed. Median time to improvement was shorter, and more patients experienced improvements with tofacitinib vs. placebo-to-tofacitinib; differences observed from W2 (first post-baseline assessment). Median time to initial (continued) ≥ 30% pain improvement was 4 (4-8) weeks for tofacitinib vs. 24 (24) weeks for placebo-to-tofacitinib (8 [8] weeks post-switch). Median time to initial (continued) ≥ 50% improvement of pain, peripheral joint pain/swelling and enthesitis, morning stiffness, BASDAI total score, and fatigue was 8-24 (12-40) weeks with tofacitinib vs. 24-32 weeks (32 weeks-not estimable [NE]) with placebo-to-tofacitinib. Median time to initial (continued) ASDAS improvement ≥ 1.1 points was 4 (8) weeks for tofacitinib vs. 24 (24) weeks for placebo-to-tofacitinib, and NE for improvement ≥ 2.0 points with either treatment.

CONCLUSIONS

Improvements in AS core domains occurred more rapidly with tofacitinib vs. placebo-to-tofacitinib. Half of tofacitinib-treated patients with AS will likely experience improvements ≥ 30% in pain and ≥ 1.1 points in ASDAS during month (M)1, ≥ 50% improvement in nocturnal pain and enthesitis by M2, and in morning stiffness by M3. Results show that initiating tofacitinib as soon as possible is associated with quicker improvements in AS core domains vs. delaying treatment.

Pain in axial spondyloarthritis: role of the JAK/STAT pathway

Axial spondyloarthritis (axSpA) is a chronic inflammatory disease that is characterized by new bone formation in the axial musculoskeletal system, with X-ray discriminating between radiographic and non-radiographic forms. Current therapeutic options include non-steroidal anti-inflammatory drugs in addition to biological disease-modifying anti-rheumatic drugs that specifically target tumor necrosis factor-alpha (TNFα) or interleukin (IL)-17. Pain is the most critical symptom for axSpA patients, significantly contributing to the burden of disease and impacting daily life. While the inflammatory process exerts a major role in determining pain in the early phases of the disease, the symptom may also result from mechanical and neuromuscular causes that require complex, multi-faceted pharmacologic and non-pharmacologic treatment, especially in the later phases. In clinical practice, pain often persists and does not respond further despite the absence of inflammatory disease activity. Cytokines involved in axSpA pathogenesis interact directly/indirectly with the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling cascade, a fundamental component in the origin and development of spondyloarthropathies. The JAK/STAT pathway also plays an important role in nociception, and new-generation JAK inhibitors have demonstrated rapid pain relief. We provide a comprehensive review of the different pain types observed in axSpA and the potential role of JAK/STAT signaling in this context, with specific focus on data from preclinical studies and data from clinical trials with JAK inhibitors.

Improvement in work productivity among psoriatic arthritis patients treated with biologic or targeted synthetic drugs: a systematic literature review and meta-analysis

BACKGROUND

Capacity to work is impacted by psoriatic arthritis (PsA). Our objective was to describe the course of work productivity and leisure activity in patients with PsA treated with biologic (b) and targeted synthetic (ts) disease-modifying antirheumatic drugs (DMARDs).

METHODS

A systematic literature review identified all trials and observational studies published January 1, 2010-October 22, 2021, reporting work productivity using the Work Productivity and Activity Impairment Questionnaire (WPAI) in patients with PsA treated with b/tsDMARDs. Outcomes for WPAI domains (absenteeism, presenteeism, total work productivity, and activity impairment) were collected at baseline and time point closest to 24 weeks of treatment. A random effects meta-analysis of single means was conducted to calculate an overall absolute mean change from baseline for each WPAI domain.

RESULTS

Twelve studies (ten randomized controlled and two observational) assessing patients treated with adalimumab, bimekizumab, guselkumab, ixekizumab, risankizumab, secukinumab, or upadacitinib were analysed. Among 3741 employed patients, overall mean baseline scores were 11.4%, 38.7%, 42.7%, and 48.9% for absenteeism, presenteeism, total work productivity impairment, and activity impairment, respectively. Estimated absolute mean improvements (95% confidence interval) to week 24 were 2.4 percentage points (%p) (0.6, 4.1), 17.8%p (16.2,19.3), 17.6%p (15.9,19.4), and 19.3%p (17.6, 21.0) respectively, leading to a mean relative improvement of 41% for total work productivity. The change in work outcomes in the b/tsDMARDs appeared similar.

CONCLUSIONS

This systematic literature review and meta-analysis confirmed that patients with active PsA have a substantially reduced capacity to work and participate in leisure activities. Substantial improvements across various WPAI domains were noted after 24 weeks of b/tsDMARD treatment, especially in presenteeism, total work productivity, and activity impairment. These findings may be useful for reimbursement purposes and in the context of shared decision-making. This systematic literature review (SLR) of randomized clinical trials and observational studies of biologic (b) and targeted synthetic (ts) disease-modifying antirheumatic drugs b/tsDMARDs in patients with PsA found that at treatment introduction, patients presented with a 42.7% mean productivity loss per week as assessed by the Work Productivity and Activity Impairment (WPAI) Questionnaire. Through a meta-analysis comparing before/after values without adjustment for placebo response, we found that after 24 weeks of treatment with b/tsDMARDs, there was a mean absolute improvement of 17.6 percentage points and a mean relative improvement of 41% in total work productivity, with similar magnitudes of improvement in time spent at work and regular activities outside of work. These results provide clinical-, regulatory- and reimbursement decision-makers with data on the potential societal and socio-economic benefits of b/tsDMARDs in PsA.

2023 EULAR recommendations for the management of fatigue in people with inflammatory rheumatic and musculoskeletal diseases

OBJECTIVES

Fatigue is prevalent in people with inflammatory rheumatic and musculoskeletal diseases (I-RMDs) and recognised as one of the most challenging symptoms to manage. The existence of multiple factors associated with driving and maintaining fatigue, and the evidence about what improves fatigue has led to a multifaceted approach to its management. However, there are no recommendations for fatigue management in people with I-RMDs. This lack of guidance is challenging for those living with fatigue and health professionals delivering clinical care. Therefore, our aim was to develop EULAR recommendations for the management of fatigue in people with I-RMDs.

METHODS

A multidisciplinary taskforce comprising 26 members from 14 European countries was convened, and two systematic reviews were conducted. The taskforce developed the recommendations based on the systematic review of evidence supplemented with taskforce members' experience of fatigue in I-RMDs.

RESULTS

Four overarching principles (OAPs) and four recommendations were developed. OAPs include health professionals' awareness that fatigue encompasses multiple biological, psychological and social factors which should inform clinical care. Fatigue should be monitored and assessed, and people with I-RMDs should be offered management options. Recommendations include offering tailored physical activity and/or tailored psychoeducational interventions and/or, if clinically indicated, immunomodulatory treatment initiation or change. Patient-centred fatigue management should consider the individual's needs and preferences, their clinical disease activity, comorbidities and other psychosocial and contextual factors through shared decision-making.

CONCLUSIONS

These 2023 EULAR recommendations provide consensus and up-to-date guidance on fatigue management in people with I-RMDs.

Altered sleep in axial spondyloarthritis and psoriatic arthritis: Post hoc comparative study based on a sleep-specific question from the ASAS health index

BACKGROUND AND AIMS

Sleep problems are common in spondyloarthritis (SpA), but the factors associated with them are only partially known. In this study, responses to item #16 from the Assessment of SpondyloArthritis international Society-Health Index (ASAS HI) that explores the sleep category according to the International Classification of Functioning, Disability and Health (ICF) were compared between psoriatic arthritis (PsA) and axial SpA (axSpA).

METHODS

Post hoc analysis of a multicentre cross-sectional study included a total of 201 consecutive patients. The prevalence, correlations, and disease factors associated with a positive response to item #16 were analyzed in both SpA populations.

RESULTS

Forty-eight/111 (43.2%) patients with axSpA and 42/90 (46.7%) with PsA reported sleep problems. There was a moderate-high correlation between item #16 and the ASAS HI sum score in both populations (r≥.59). In axSpA, poor sleep was associated with disease activity (OR 8.45, p<.001), biological therapy use (OR .24, p<.05) and CRP levels (OR .16, p<.05). In PsA, disturbed sleep was independently associated with disease activity showing a dose-response effect (OR 1.16, p<.001). Taking both populations together, disease severity (OR 6.33, p<.001) and axSpA (OR .50, p<.05) were independently associated with a positive response to item #16. Correlations between the different components of the ASAS HI and item #16 were markedly different in both populations.

CONCLUSIONS

A positive response to item #16 was common in both SpA phenotypes. However, the link between inflammatory burden and disturbed sleep was higher in axSpA than in PsA.

Awareness, perspectives and satisfaction levels among patients with psoriatic arthritis: a multicentric cross-sectional survey

Perception of the disease and its management impacts patients with Psoriatic arthritis (PsA) to a great degree. Studies examining patients' viewpoints and perception of their disease and its management are scarce. This multicentric cross-sectional survey was undertaken to understand the perspectives of patients with PsA. A survey questionnaire with items on demographics, awareness about their disease, treatment, physical therapy, quality of life and satisfaction with the care received was designed. After internal and external validation, a pilot survey was conducted, and the questionnaire was finalized. The final survey (with translations in local languages) was carried out at 17 centres across India. There were 262 respondents (56% males) with mean age of 45.14 ± 12.89 years. In 40%, the time lag between onset of symptoms and medical assessment for it was more than a year. In most of the patients, the diagnosis of PsA was made by a rheumatologist. Over 83% of patients were consulting their rheumatologist periodically as advised and fully compliant with the treatment. Lack of time and cost of therapy were the most common reasons for non-adherence to therapy. Eighty-eight patients (34%) were not fully satisfied with their current treatment. Over two-third of patients had never seen a physiotherapist due to barriers including a lack of time, pain, and fatigue. The daily activities and employment status were affected in nearly 50% of patients with PsA. The current survey has identified a gap in patients' awareness levels and helps healthcare providers in understanding the varied perceptions of patients with PsA. Addressing these issues in a systematic manner would potentially improve the treatment approaches, outcomes, and patient satisfaction levels.

Exploring pain catastrophizing and its associations with low disease activity in rheumatic inflammatory disorders

Pain catastrophizing is a maladaptive mechanism associated with the exaggerated experience of pain, increased rumination and feelings of helplessness. The main objective of this study was to explore whether increased pain catastrophizing is independently associated with a lower proportion of low disease activity (LDA) in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondylarthritis (axSpA). Demographics, comorbidities, treatment, disease activity measures and patient-reported outcome data were recorded in RA, PsA and axSpA patients. Pain catastrophizing score (PCS) was assessed using a standardised questionnaire. For each diagnosis, composite disease activity scores with distinct cut-off values for LDA, i.e. DAS28-CRP (RA), DAPSA (PsA) and ASDAS-CRP (axSpA) were calculated and used as the dependent variable in logistic regression reflecting LDA achieved. A total of one thousand two hundred and twenty nine patients were included: 580 with RA, 394 with PsA and 255 with axSpA. In the multivariable analysis, pain catastrophizing was independently associated with LDA rates in axSpA (OR 0.33, 95% CI [0.12, 0.88]) amongst tested groups. In RA (OR 0.90, 95% CI [0.64, 1.28]) and PsA (OR 0.77, 95% CI [0.55, 1.07]), a statistically significant association was not observed. Higher PCS was independently associated with not achieving LDA in axSpA. Our data, however, indicate that pain catastrophizing, which also reflects a patient's personality traits and coping abilities, plays a less important role for the patient than general pain perception.

Evaluating remission and low disease activity from the perspective of the patient with axial spondyloarthritis: The cross-sectional ConREspAx study

OBJECTIVES

To evaluate the properties of a single question to determine patient perception of remission and disease activity; to compare this with existing definitions for remission and low disease activity (LDA).

METHODS

Single-center, cross-sectional study in a tertiary care hospital. Patients with axSpA (fulfilling ASAS criteria) were consecutively included. Both the patient's perception of remission and LDA and that of the physician were evaluated with a single question. Agreement between the patients' perception and other current definitions was tested using the prevalence-adjusted and bias-adjusted kappa (PABAK). The sensitivity (S) and specificity (Sp) of current definitions of disease states were tested against the patient's perception as the gold standard.

RESULTS

The study population included 105 axSpA patients (63.8% males; 67.6% with radiographic sacroiliitis). Patients considered themselves to be in remission in 21% of cases and in LDA in 51.4%; physicians considered patients to be in remission in 45.7% of cases and in LDA in 35.2%. The poorest agreement was recorded for the patient's and the physician's perception of remission. The best agreement for patients' perception of remission was for a BASDAI < 2 and normal C-reactive protein values. This definition was also the most sensitive (S=72.7%) and specific (Sp=83.1%) when the patient's perception was taken as the gold standard.

CONCLUSION

In a real-life setting, the evaluation of remission by the patient through a single question was the hardest criterion to achieve, although it did prove to be a feasible, valid, and specific way to assess remission.

Differentiated Effect of Smoking on Disease Activity and Quality of Life among Different Spondyloarthritis Phenotypes

BACKGROUND AND AIMS

The effect of smoking on disease activity and quality of life (QoL) in spondyloarthritis (SpA) is far from clear. We aimed to evaluate the relationship between smoking and these outcomes in patients with axial SpA (axSpA) and psoriatic arthritis (PsA).

PATIENTS AND METHODS

This cross-sectional observational multicenter study included 242 patients with axSpA and 90 with PsA. The association between conventional cardiovascular risk factors and disease activity as well as QoL, in both SpA phenotypes was evaluated. For this, univariate and multivariate regression analyses were performed, as well as confirmatory meta-analyses.

RESULTS

Regardless of age, sex, or disease duration, patients with axSpA showed significantly less association with obesity (OR 0.50 (0.26-0.96), p = 0.03) and hypertension (OR 0.33 (0.18-0.62), p = 0.0005). However, axSpA was significantly associated with smoking (OR 2.62 (1.36-5.04), p = 0.004). Patients with axSpA were more likely to be in a category of high disease activity compared with PsA (OR 2.86, p = 0.0006). Regardless of sex, age, disease duration, and education level, smoking was significantly associated with higher disease activity in axSpA (OR 1.88, p = 0.027). A fixed-effects model meta-analysis (OR 1.70, p = 0.038) confirmed the association between tobacco and disease activity. No relationship was found between smoking (or other cardiometabolic risk factors) and structural damage or worse QoL in either disease.

CONCLUSIONS

Although the cardiometabolic risk profile is clearly different between both SpA phenotypes, the only clear link between these factors and increased disease activity was observed between smoking and axSpA. Our findings need further confirmation.

Characteristics associated with the perception of high-impact disease (PsAID ≥4) in patients with recent-onset psoriatic arthritis. Machine learning-based model

OBJECTIVES

To evaluate which patient and disease characteristics are associated with the perception of high-impact disease (PsAID ≥4) in recent-onset psoriatic arthritis.

METHODS

We performed a multicenter observational prospective study (2-year follow-up, regular annual visits). The study population comprised patients aged ≥18 years who fulfilled the CASPAR criteria and less than 2 years since the onset of symptoms. The dataset was generated using data for each patient at the 3 visits (baseline, first year, and second year of follow-up) matched with the PsAID values at each of the 3 visits. PsAID was categorized into two groups (<4 and ≥4). We trained a logistic regression model and random forest-type and XGBoost machine learning algorithms to analyze the association between the outcome measure and the variables selected in the bivariate analysis. A k-fold cross-validation with k = 5 was performed.

RESULTS

The sample comprised 158 patients. Of the patients who attended the clinic, 45.8% scored PsAID ≥4 at baseline; 27.1%, at the first follow-up visit, and in 23.0%, at the second follow-up visit. The variables associated with PsAID ≥4 were, in decreasing order of importance: HAQ, pain, educational level, and physical activity. Higher HAQ (logistic regression coefficient 10.394; IC95% 7.777,13.011), higher pain (5.668; 4.016, 7.320), lower educational level (-2.064; -3.515, -0.613) and high level of physical activity (1.221; 0.158, 2.283) were associated with a higher frequency of PsAID ≥4. The mean values of the measures of validity of the algorithms were all ≥85%.

CONCLUSIONS

Despite the higher weight given to pain when scoring PsAID, we observed a greater influence of physical function on disease impact.

Minimal disease activity (MDA) in patients with recent-onset psoriatic arthritis: predictive model based on machine learning

Background

Very few data are available on predictors of minimal disease activity (MDA) in patients with recent-onset psoriatic arthritis (PsA). Such data are crucial, since the therapeutic measures used to change the adverse course of PsA are more likely to succeed if we intervene early. In the present study, we used predictive models based on machine learning to detect variables associated with achieving MDA in patients with recent-onset PsA.

Methods

We performed a multicenter observational prospective study (2-year follow-up, regular annual visits). The study population comprised patients aged ≥18 years who fulfilled the CASPAR criteria and less than 2 years since the onset of symptoms. The dataset contained data for the independent variables from the baseline visit and from follow-up visit number 1. These were matched with the outcome measures from follow-up visits 1 and 2, respectively. We trained a random forest–type machine learning algorithm to analyze the association between the outcome measure and the variables selected in the bivariate analysis. In order to understand how the model uses the variables to make its predictions, we applied the SHAP technique. We used a confusion matrix to visualize the performance of the model.

Results

The sample comprised 158 patients. 55.5% and 58.3% of the patients had MDA at the first and second follow-up visit, respectively. In our model, the variables with the greatest predictive ability were global pain, impact of the disease (PsAID), patient global assessment of disease, and physical function (HAQ-Disability Index). The percentage of hits in the confusion matrix was 85.94%.

Conclusions

A key objective in the management of PsA should be control of pain, which is not always associated with inflammatory burden, and the establishment of measures to better control the various domains of PsA.

Effect of upadacitinib on reducing pain in patients with active psoriatic arthritis or ankylosing spondylitis: post hoc analysis of three randomised clinical trials

Objective

Evaluate the effect of upadacitinib on pain outcomes in patients with active psoriatic arthritis (PsA) or ankylosing spondylitis (AS) across 3 randomised trials (SELECT-PsA 1 and 2 for PsA; SELECT-AXIS 1 for AS).

Methods

Patients were randomised to upadacitinib 15 mg once daily or placebo (all 3 studies), or adalimumab 40 mg every other week (SELECT-PsA 1 only). Pain outcomes included proportion of patients achieving ≥30%, ≥50% and ≥70% reduction from baseline in patient global assessment of pain and other end points.

Results

A higher proportion of patients receiving upadacitinib versus placebo achieved ≥30%, ≥50% and ≥70% reduction in pain end points as early as week 2; these improvements with upadacitinib were generally sustained or increased through year 1 (PsA 1/2 studies: 64%/48%, 58%/42% and 38%/22%, respectively; SELECT-AXIS 1 study: 76%, 72% and 54%). Results were similar with adalimumab in PsA 1 (59%, 49% and 32%). Patients who switched from placebo to upadacitinib 15 mg were able to reach a similar level of improvement as the continuous upadacitinib groups by year 1 (PsA 1/2 studies: 46%–60%, 35%–49% and 15%–34%; AS study: 83%, 72% and 46%). Results were similar with other pain end points.

Conclusion

Rapid and sustained improvements in pain outcomes across several end points were consistently shown with upadacitinib over 1 year in patients with active PsA or AS who had either inadequate response to prior non-biologic or biologic disease-modifying antirheumatic drugs (PsA studies) or were biologic-naïve with inadequate response to non-steroidal anti-inflammatory drugs (AS study).

Patient Perception of Medical Care for Psoriatic Arthritis in North America and Europe: Results from a Global Patient Survey

Introduction

To compare perceptions of disease control and treatment satisfaction between patients with psoriatic arthritis (PsA) in North America and Europe, and between participating countries within each region.

Methods

Data were collected from patients with self-reported PsA diagnoses using an online survey. Results from questions on perceptions of overall health, disease severity, PsA symptoms, PsA impacts, and treatment satisfaction/preferences were reported using descriptive statistics and Chi-square tests.

Results

A total of 456 patients from North America (Canada, n = 155; US, n = 301) and 417 patients from Europe (France, n = 123; Spain, n = 135; UK, n = 159) were included in this analysis. Patients in North America were more likely to rate their overall health as excellent/good compared with those in Europe (49 vs. 14%), but also rate their disease as severe (27 vs. 15%). Despite treatment, patients in North America and Europe still experienced musculoskeletal (92 vs. 91%) and skin/nail (62 vs. 58%) symptoms. Similar proportions of patients in North America vs. Europe experienced a social impact (81 vs. 85%); more patients in Europe vs. North America experienced PsA-related work impacts (83 vs. 74%). Satisfaction with PsA medication was more common in North America (89%) vs. Europe (79%), and more common in Spain (91%) vs. the UK (82%) or France (66%). Across all regions and countries, ≥ 75% of patients agreed that symptoms were controlled. However, ≥ 66% wished they had more medication choices, and ≥ 84% wanted to change something about their medication.

Conclusions

Although perception of overall health and disease severity varied, many patients from both regions still experienced symptoms despite receiving medications for PsA, wished they had greater choice of medications, and/or would like to change an aspect of their medications. While these survey findings are subject to selection bias, they do indicate there is scope to improve the treatment of PsA.

Supplementary Information

The online version contains supplementary material available at 10.1007/s40744-022-00435-y.

Psoriatic arthritis (PsA) is a disease that can cause joint pain and stiffness, and is often associated with a skin rash called psoriasis. These symptoms can affect quality of life, and patients and doctors should work together when choosing treatment. There has not been a lot of information on what patients think about their disease and their medicines. We found that patients from different regions and countries had different opinions, and that treatment of PsA can be improved. For example, patients in North America were more likely to say that their overall health was excellent or good, compared with patients in Europe. However, more patients in North America than in Europe described their PsA disease as severe. Similar numbers of patients in both regions experienced impacts on their social life due to their PsA, but patients in Europe were more likely to report that PsA affected their work life compared with patients in North America. More patients in North America than in Europe were satisfied with their medicines, but patients across all regions and countries still had symptoms even when they took medicines. Many patients also wished they had more options and wanted to change something about their medicines. These findings were based on an online survey. Patients from North America (Canada and the US) and Europe (France, Spain, and the UK) answered questions about their PsA disease and medicines. We only compared answers between patients from North America and Europe, and between countries within each region.

Qualitative interview study exploring the patient experience of living with axial spondyloarthritis and fatigue: difficult, demanding and draining

OBJECTIVE

To explore patients' lived experiences of axial spondyloarthritis (axSpA) and fatigue.

DESIGN

Interpretative phenomenological analysis (lived experience) was used as the study design. Analysis drew together codes with similar meaning to create superordinate and subordinate themes.

SETTING

Rheumatology departments in three National Health Service Foundation Trusts in the north, midlands and south of England.

PARTICIPANTS

A purposive sample of seventeen axSpA patients were recruited. The age range was 22-72 years (median age 46), nine were male and eight, female.

RESULTS

A central concept of achieving balance was identified as the active process of integrating axSpA symptoms and fatigue into daily life, working with and not against their condition to lead a fulfilled life. This was conveyed through three superordinate themes: struggling to find energy, engaging in everyday life and persevering through difficulties. Struggling to find energy was the challenge of retaining enough stamina to do things in daily life. Engaging in everyday life highlighted dedication to being active and organised, learning through experience and acceptance of a changed way of being. Persevering through difficulties identified the physical and emotional effort required to keep moving forward and the importance of feeling supported.

CONCLUSION

Achieving balance through finding energy, engaging and persevering everyday was fundamental to having the best possible life. The experience of energy emerged as a distinct but related component of fatigue. However, while energy could be maintained or replenished, fatigue was more difficult to overcome and required greater effort. Energy may be a useful indicator of an individual's current state and ability to sustain activities that supports their well-being, such as exercise. Awareness of the elements of achieving balance in axSpA may enable patients and clinicians to work together to tailor treatments to individual patient need.

Time to response for clinical and patient-reported outcomes in patients with psoriatic arthritis treated with tofacitinib, adalimumab, or placebo

Background

This study examined the time to clinically meaningful response in patients with active psoriatic arthritis treated with tofacitinib, adalimumab, or placebo switching to tofacitinib.

Methods

Data were from two phase 3 studies, OPAL Broaden (12 months) and OPAL Beyond (6 months). Patients received tofacitinib 5 or 10 mg twice daily (BID), adalimumab 40 mg once every 2 weeks (OPAL Broaden only), or placebo switching to tofacitinib 5 or 10 mg BID at month 3. Baseline to initial response time was according to pre-defined clinically meaningful criteria on Health Assessment Questionnaire-Disability Index (HAQ-DI; ≥ 0.35-point improvement), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F; ≥ 4-point improvement), Psoriatic Arthritis Disease Activity Score (PASDAS; post-baseline score ≤ 3.2 and > 1.6-point improvement from baseline), and minimal disease activity (MDA; meeting at least 5 of 7 criteria) composite.

Results

In OPAL Broaden, median time to initial HAQ-DI score response was 29, 53, and 30 days in patients treated with tofacitinib 5 mg BID, tofacitinib 10 mg BID, or adalimumab, compared with 162 and 112 days in patients treated with placebo switching to tofacitinib 5 or 10 mg BID at month 3, respectively. Across studies, median time to initial FACIT-F total score response was shorter in patients receiving tofacitinib 5 mg BID (31 days) vs other groups (84–92 days). Median time to initial response was approximately 11 (MDA)/6–9 months (PASDAS) in tofacitinib/adalimumab groups in OPAL Broaden.

Conclusion

This analysis demonstrates tofacitinib’s efficacy on most patient-reported and clinical endpoints over time and shows a shorter time to initial, clinically meaningful response in patients receiving tofacitinib vs patients switching from placebo to tofacitinib.

Pain and Fatigue in Patients With Ankylosing Spondylitis Treated With Tumor Necrosis Factor Inhibitors: Multinational Real-World Findings

BACKGROUND/OBJECTIVE

Patients with ankylosing spondylitis (AS) experience symptoms and comorbidities that impact their health-related quality of life (HRQoL) and ability to work. This real-world, global survey was conducted among AS patients receiving tumor necrosis factor inhibitors (TNFis) to evaluate both the frequency and severity of persistent symptoms, and the impact of pain and fatigue on HRQoL, employment status, and work activity.

METHODS

Patients with AS and their treating physicians from 13 countries across 5 continents completed questionnaires capturing demographics, patient symptoms, current disease status, HRQoL, current therapy, employment status, and Work Productivity and Activity Impairment.

RESULTS

Seven hundred five patients who had been receiving a TNFi for 3 months or more and completed both Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) pain and fatigue domains were included in the analysis; of these, 37.6% reported high BASDAI pain scores and 41.3% high BASDAI fatigue scores. Medical Outcomes Study-Short Form, 36-item version 2 domain, 5-dimensional EuroQoL Questionnaire, and 5-dimensional EuroQoL visual analog scale scores were significantly lower (p < 0.0001), and Work Productivity and Activity Impairment scores significantly higher (p < 0.0001), in patients with high levels of pain or fatigue than low levels.

CONCLUSIONS

Globally, levels of pain and fatigue remained high in AS patients receiving TNFi treatment, which were significantly associated with reduced HRQoL and work productivity. Such persistent symptoms in usual care suggest a substantial unmet need in AS pharmacologic and nonpharmacologic therapeutic pathways.

The effects of golimumab on work productivity and quality of life among work-active axial spondyloarthritis and psoriatic arthritis patients treated in the routine care in Greece: the 'GO-UP' study

PURPOSE

To examine the impact of golimumab, on work productivity, activity limitation, and quality of life (QoL) in patients with axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA).

METHODS

This real-world, multicenter, prospective study consecutively enrolled adult consented work-active patients with axSpA or PsA, newly initiated on golimumab as per the approved label. Prior receipt of > 1 prior biologic, or switching from another tumor-necrosis factor inhibitor due to primary non-response or safety reasons was not allowed. The Work Productivity and Activity Impairment-Specific Health Problem and the EuroQol 5-Dimensions (EQ-5D)-5-Level instruments were completed by the patients to assess the impact of golimumab on work productivity and activity impairment, and generic QoL, respectively.

RESULTS

Overall, 121 eligible patients (mean age: 45.4 years; median disease duration: 11.3 months), 51 diagnosed with PsA and 70 with axSpA, were enrolled by 19 rheumatologists. Over a 11.9-month median observation period, < 1% of injections were missed (as collected by patient diaries), and the 12-month golimumab retention rate was 91.7%. At 3, 6, and 12 months post baseline, in the overall population, work productivity loss improved by a median of 31.4%, 44.2%, and 50.0%; activity impairment improved by 40.0%, 40.0%, and 50.0%; and the EQ-5D UK-weighted utility index improved by 0.24, 0.32, and 0.36 points, respectively (p < 0.001 for all). Statistically significant improvements in these measures were also noted in the PsA and axSpA subpopulations.

CONCLUSION

In the routine care in Greece, golimumab displays beneficial effects on work productivity, daily activities, and QoL in work-active patients with axSpA and PsA.

Rapid improvement in spinal pain in patients with axial spondyloarthritis treated with secukinumab: primary results from a randomized controlled phase-IIIb trial

BACKGROUND

This study aimed to evaluate the efficacy and safety of secukinumab 150 mg compared with placebo in the management of spinal pain and disease activity in patients with axial spondyloarthritis (axSpA) at Week 8 and up to Week 24.

METHODS

Patients (n = 380) with active axSpA were randomized (3:1) to secukinumab 150 mg (Group A) or placebo (Group B). At Week 8, patients from Group A with an average spinal pain score <4 were defined as responders and were re-assigned to secukinumab 150 mg (Arm A1); whereas non-responders were re-randomized to secukinumab 150/300 mg (Arm A2/A3). Patients from Group B were re-randomized (1:1) to secukinumab 150/300 mg (Arm B1/B2).

RESULTS

At Week 8, the odds of achieving an average spinal pain score of <4 were significantly higher for patients on secukinumab 150 mg than for patients on placebo (odds ratio (OR): 1.89; 95% confidence interval (CI): 1.08-3.33; p = 0.0264). Further reductions in spinal pain were observed across treatment groups up to Week 24. Pronounced improvements were also observed in other disease activity measurements, such as Bath Ankylosing Spondylitis Disease Activity Index and Ankylosing Spondylitis Disease Activity Score. Responders from Group A showed the highest improvements for all measured parameters of spinal pain compared with the other arms. No new or unexpected safety signals were observed.

CONCLUSION

Secukinumab provided rapid and significant improvement in spinal pain at Week 8 which was sustained or increased further up to Week 24 in patients with axSpA.

Exploring the Quality of Communication Between Patients with Psoriatic Arthritis and Physicians: Results of a Global Online Survey

INTRODUCTION

Effective communication between patients with psoriatic arthritis (PsA) and their physicians is important for optimizing treatment outcomes. We assessed the quality of patient-physician communication in terms of awareness and impact of PsA symptoms, their levels of satisfaction, and their perceptions of communications.

METHODS

A global online survey was conducted by The Harris Poll in adult patients with PsA and physicians managing patients with PsA in eight countries. Participating physicians were either rheumatologists or dermatologists seeing ≥ 10 and ≥ 5 patients with PsA per month, respectively. Patient and physician groups were unmatched. Patient-physician communication was assessed with 35-60 questions regarding discussion topics during consultations, levels of satisfaction with communication, and specific communication issues.

RESULTS

A total of 1286 patients with PsA (983 and 303 whose primary treating physician was a rheumatologist or dermatologist, respectively) and 1553 physicians (795 rheumatologists and 758 dermatologists) completed the survey. Regardless of whether they were primarily treated by a rheumatologist or dermatologist, most patients reported a social (84% and 81%, respectively) or work (81% and 80%, respectively) impact of PsA, and a major/moderate negative impact on their physical activity levels (79% and 74%, respectively) or emotional/mental wellbeing (69% and 68%, respectively). Physician responses were generally consistent with this; however, physicians often appeared to under-recognize the extent to which PsA affects patients. Most (≥ 85%) patients and physicians were very/somewhat satisfied with their patient-physician communication, and most (≥ 86%) patients were comfortable raising their concerns/fears with their physician. However, > 40% of patients were identified as being at risk of suboptimal communication. These patients were significantly less likely to report their PsA symptoms even when asked, were less comfortable discussing the impacts of PsA with their physician, and were more likely to experience major/moderate impacts of PsA on their health-related quality of life (HRQoL).

CONCLUSIONS

Physicians often underestimate the impacts of PsA, compared with patients, and some patients may be at risk of suboptimal communication with their attending physician, which may worsen the HRQoL impacts of PsA. These findings highlight a need for ways to improve communication between patients with PsA and their healthcare providers.

Ixekizumab improves sleep and work productivity in patients with non-radiographic axial spondyloarthritis: results from the COAST-X trial at 52 weeks

Background

Patients with non-radiographic axial spondyloarthritis experience negative impacts on sleep, work productivity, and activity impairment. Ixekizumab, a monoclonal antibody selectively targeting interleukin-17A, has shown efficacy in treating the signs and symptoms of non-radiographic axial spondyloarthritis. This analysis evaluated the effect of ixekizumab treatment on sleep, work productivity, and activity impairment in patients with non-radiographic axial spondyloarthritis.

Methods

COAST-X (NCT02757352) was a 52-week, phase 3, multicenter, randomised placebo-controlled trial evaluating 80-mg ixekizumab every 2 weeks and every 4 weeks in patients with active non-radiographic axial spondyloarthritis. Sleep disturbance was measured with the Jenkins Sleep Evaluation Questionnaire (JSEQ) and analysed using mixed-effects models for repeated measures. Work productivity and activity impairment were measured using the Work Productivity and Activity Impairment Questionnaire for Spondyloarthritis and analysed using analysis of covariance. Absenteeism, presenteeism, and overall work impairment were assessed for patients reporting paid work; activity impairment was assessed regardless of work status.

Results

Overall, patients treated with both dosing regimens of ixekizumab reported numerically greater improvements in sleep than placebo through Week 52. At Weeks 16 and 52, patients treated with ixekizumab every 4 weeks had significantly greater improvements in presenteeism (p = 0.007 and p = 0.003, respectively) and overall work impairment (p = 0.014 and p = 0.005, respectively) and numeric improvements in absenteeism than placebo. Patients treated with ixekizumab every 2 weeks had numerically greater improvements in absenteeism, presenteeism, and overall work impairment than placebo. Both dosing regimens of ixekizumab were associated with significantly greater improvements in activity impairment than placebo (ixekizumab every 4 weeks: p = 0.003 at Week 16 and p = 0.004 at Week 52; ixekizumab every 2 weeks: p = 0.007 at Week 16 and p = 0.006 at Week 52).

Conclusions

Treatment with ixekizumab improved sleep, work productivity, and activity impairment in patients with nr-axSpA. Improvements in presenteeism and overall work impairment were sustained and consistent in the patients treated with ixekizumab every 4 weeks from Week 16 to Week 52. Improvements in activity impairment were sustained and consistent in both ixekizumab-treated groups from Week 16 to Week 52.

Preferences for biologic treatment in patients with psoriatic arthritis: a discrete choice experiment

OBJECTIVES

We aimed to assess patient preferences for the characteristics and outcomes of biologic and targeted synthetic DMARDs to manage psoriatic arthritis.

METHODS

We conducted a discrete choice experiment in patients with psoriatic arthritis from three rheumatology centers in Sydney, Australia. We assessed preferences for different attributes of biologic medications. The route and frequency of medications had a range of five levels and the following seven attributes had a range of three levels: the ability to attend to normal activities, improvements in joint pain, enthesitis and skin disease, chance of disease remission, risk of infection and risk of severe adverse events. Multinomial logit models including a latent class model were used to calculate preferences.

RESULTS

Of the 150 participants, 58.3% were female, with a median age of 53.5 years. The attributes in order of preference were (β coefficient in absolute values, 95% confidence interval): oral route compared to subcutaneous and intravenous routes (β coefficient 1.00, fixed-parameter), avoiding severe side effects (0.72, 0.50 to 0.95), increasing ability to attend to normal activities (0.66, 0.36 to 0.96), avoiding infections (0.38, 0.23 to 0.53), improvement in enthesitis pain (0.28, 0.20 to 0.36), improvement in psoriasis (0.28, CI 0.20 to 0.36), increasing chance of remission (0.27, 0.19 to 0.36) and improvement in joint pain (0.26, 0.00 to 0.52).

CONCLUSION

When choosing biologic medications, patients with psoriatic arthritis preferred oral medications. Patients prioritized avoiding severe complications, maintaining the ability to attend to work and normal activities and avoiding infection over clinical measures of efficacy.

Effectiveness and persistence of golimumab as a second biological drug in patients with spondyloarthritis: A retrospective study

This observational, longitudinal retrospective, noncomparative study was designed to assess the persistence and effectiveness of golimumab as a second anti-tumor necrosis factor (TNF) drug in patients with spondyloarthritis requiring discontinuation from a first anti-TNF drug.Data were collected retrospectively for all patients with axial spondyloarthritis or psoriatic arthritis from 20 rheumatology clinics in Spain who started golimumab as a second anti-TNF drug between January 2013 and December 2015. Golimumab persistence was assessed with Kaplan-Meier survival analysis, and associated factors were assessed with Cox regression analysis.210 patients started golimumab as a second anti-TNF drug: 131 with axial spondyloarthritis and 79 with psoriatic arthritis. In axial spondyloarthritis patients, the mean (standard deviation) Bath Ankylosing Spondylitis Disease Activity Index score at baseline was 5.5 (2.1), decreasing to 3.9 (2.0) at month 3 and 3.5 (2.0) at year 1, and remaining stable thereafter. In psoriatic arthritis patients, mean (standard deviation) baseline Disease Activity Score was 4.0 (1.3), reducing to 2.5 (1.2) at month 3 and to 2.2 (1.3) at year 1. Corresponding improvements were recorded from baseline in C-reactive protein levels and erythrocyte sedimentation rates. The probability of persistence of treatment with golimumab was 80% at year 1, 70% at year 2 and 65% at years 3 and year 4, and was similar in those who had stopped the first anti-TNF due to loss of efficacy or other reasons. Cox regression analysis showed that the probability of survival with golimumab was higher in patients with higher erythrocyte sedimentation rate, in patients with axial spondyloarthritis than with psoriatic arthritis, and in those who had discontinued adalimumab as first anti-TNF. Seventy-two patients (34.3%) discontinued golimumab during follow-up, 50 of them due to lack of efficacy.In patients with spondyloarthritis requiring discontinuation from a first anti-TNF drug, treatment with golimumab was effective and showed a high probability of persistence up to 4 years of treatment.

Patient Perceptions of Psoriatic Arthritis Management and Communication with Physicians in Australia: Results from a Patient Survey

Introduction

The objective of this report was to evaluate perceptions of psoriatic arthritis (PsA) treatment and satisfaction with healthcare professional (HCP) communication among patients with PsA in Australia, compared with overall global perceptions.

Methods

Data were collected via a global and country-specific survey (The Harris Poll; November 2, 2017–March 12, 2018). Eligible patients were ≥ 18 years old, had been diagnosed with PsA > 1 year prior, had seen a rheumatologist or dermatologist within the past 12 months, and had previously received ≥ 1 conventional synthetic or biologic disease-modifying antirheumatic drug. Data reported by patients included baseline demographics, overall health, time since PsA diagnosis, PsA severity, satisfaction with current PsA medication and management, and experiences regarding communication with their HCP. Descriptive statistics were obtained.

Results

Most patients in Australia were very or somewhat satisfied with their PsA medication, and reported always or often taking their medication exactly as directed by their HCP. However, the majority still experienced symptoms, reported their overall health as poor or fair, and would change something about their PsA medication. While the majority of patients in Australia were satisfied with the communication with their HCP, most would prefer increased communication but some felt that asking too many questions would affect the quality of their care. Perceptions in Australia were similar to global perceptions.

Conclusions

Although most patients with PsA in Australia were satisfied with their disease management and communication with their HCP, many still experienced symptoms, would change something about their PsA medication, and would prefer increased communication with their HCP.

Psoriatic arthritis (PsA) can cause tender and swollen joints. If not treated properly, the joint damage can get worse, until patients struggle to cope with everyday tasks. Patients and their doctors need to communicate well to successfully manage PsA. We used an online survey to ask patients in Australia how they feel about their PsA medication and the way they communicate with their doctor. These patients were adults who had had PsA for more than 1 year, had seen a specialist doctor in the past year, and had taken one or more prescription PsA medications. A total of 152 patients in Australia completed the survey. Most patients were very or somewhat satisfied with the PsA medication they were taking, and most always or often took it exactly as their doctor told them to. However, almost all patients still had symptoms, most said their overall health was poor or fair, and most would like to change something about their medication. While most patients were satisfied with the communication with their doctor about PsA, most wished they talked more with their doctor about their PsA and treatment goals, but some felt that asking too many questions would harm their quality of care. Patients in Australia had similar answers to patients who answered the survey in other countries. Although the survey was limited by the number of patients who responded, and whether patients answered questions properly, it suggests that patients and doctors need to communicate more closely to improve PsA management.

A quality indicator set for rehabilitation services for people with rheumatic and musculoskeletal diseases demonstrates adequate responsiveness in a pre-post evaluation

BACKGROUND

Quality of care is gaining increasing attention in research, clinical practice, and health care planning. Methods for quality assessment and monitoring, such as quality indicators (QIs), are needed to ensure health services in line with norms and recommendations. The aim of this study was to assess the responsiveness of a newly developed QI set for rehabiliation for people with rheumatic and musculoskeletal diseases (RMDs).

METHODS

We used two yes/no questionnaires to measure quality from both the provider and patient perspectives, scored in a range of 0-100% (best score, 100%). We collected QI data from a multicenter stepped-wedge cluster-randomized controlled trial (the BRIDGE trial) that compared traditional rehabilitation with a new BRIDGE program designed to improve quality and continuity in rehabilitation. Assessment of the responsiveness was performed as a pre-post evaluation: Providers at rehabilitation centers in Norway completed the center-reported QIs (n = 19 structure indicators) before (T1) and 6-8 weeks after (T2) adding the BRIDGE intervention. The patient-reported QIs comprised 14 process and outcomes indicators, measuring quality in health services from the patient perspective. Pre-intervention patient-reported data were collected from patients participating in the traditional program (T1), and post-intervention data were collected from patients participating in the BRIDGE program (T2). The patient groups were comparable. We used a construct approach, with a priori hypotheses regarding the expected direction and magnitude of PR changes between T1 and T2. For acceptable responsivess, at least 75% of the hypotheses needed to be confirmed.

RESULTS

All eight participating centers and 82% of the patients (293/357) completed the QI questionnaires. Responsiveness was acceptable, with 44 of 53 hypotheses (83%) confirmed for single indicators and 3 of 4 hypotheses (75%) confirmed for the sum scores.

CONCLUSION

We found this QI set for rehabilitation to be responsive when applied in rehabilitation services for adults with various RMD conditions. We recommend this QI set as a timely method for establishing quality-of-rehabilitation benchmarks, promoting important progress toward high-quality rehabilitation, and tracking trends over time.

TRIAL REGISTRATION

The study is part of the larger BRIDGE trial, registered at ClinicalTrials.gov (Identifier: NCT03102814).

Psychometric validation of a patient-reported outcome questionnaire (Qualipsosex) assessing the impact of psoriasis and psoriatic arthritis on patient perception of sexuality

ABSTRACT

Psoriasis (Pso) and psoriatic arthritis (PsA) frequently have a negative impact on patients' sexual health. We have developed a specific questionnaire assessing the impact of Pso and PsA on patient perception of sexuality: the QualipsoSex Questionnaire (QSQ). The aim of the present study was to further validate this questionnaire by checking its psychometric properties including validity, reliability, and responsiveness.A cross sectional observational study with a longitudinal component for responsiveness and test-retest reliability was performed in 12 centers in France including 7 dermatologists and 5 rheumatologists. Psychometric properties were examined according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) check-list.At baseline, 114 patients had Pso and 35 patients had PsA including 17 peripheral arthritis, 4 axial disease, 13 patients with both axial disease and peripheral arthritis and one patient with an undifferentiated phenotype. The mean Pso Area and Severity Index score was 12.5. Genital organs were involved in 44.7% of Pso cases. Internal consistency, construct validity, and reliability were good with Cronbach's α coefficient, measure of sampling adequacy and intraclass correlation coefficient respectively at 0.87, 0.84, and 0.93. The QSQ also demonstrated acceptable sensitivity to change.The QSQ has demonstrated good psychometric properties fulfilling the validation process relative to the recommendations of the COSMIN check list. The QSQ is simple to score and may hopefully be valuable in clinical practice and in clinical trials.

Content validity of the ASQoL for use in a non-radiographic axial spondyloarthritis population: a qualitative study

Purpose

The ankylosing spondylitis quality of life (ASQoL) instrument is widely used to assess health-related quality of life in patients with ankylosing spondylitis (AS). We assessed the relevance of the ASQoL items in patients with non-radiographic axial spondyloarthritis (nr-axSpA), a distinct subgroup within the axSpA disease spectrum.

Methods

This observational, cross-sectional, qualitative interview study recruited patients from clinic settings. Interviews from patients with axSpA who participated in a prior qualitative study were also used. Patients initially underwent a concept elicitation interview using open-ended questions to evaluate relevance of the concepts measured by the ASQoL. They then completed the ASQoL and underwent a cognitive interview to assess their understanding of the items, instructions and response options. Transcripts from patients who participated in the previous qualitative study (who did not complete the ASQoL or undergo cognitive interview) were evaluated to identify expressions of the concepts in the ASQoL.

Results

A total of 18 patients with nr-axSpA participated. The concept elicitation interview findings supported the relevance of the ASQoL items. Cognitive interviews determined that the ASQoL was easily understood; the 13 new patients chose a response for each item that matched their experience with nr-axSpA. Transcripts for the five previously interviewed patients confirmed the concepts presented in the ASQoL items were relevant and important to their experience of living with nr-axSpA.

Conclusions

Our results represent an important first step in confirming the relevance of the concepts in the ASQoL to patients with nr-axSpA, supporting quantitative assessment of ASQoL validity in this population.

Dual neutralisation of interleukin-17A and interleukin-17F with bimekizumab in patients with active ankylosing spondylitis: results from a 48-week phase IIb, randomised, double-blind, placebo-controlled, dose-ranging study

OBJECTIVES

Bimekizumab selectively neutralises both interleukin (IL)-17A and IL-17F. We report efficacy and safety in a phase IIb dose-ranging study in patients with active ankylosing spondylitis (AS).

METHODS

Adults with AS (fulfilling modified New York criteria) were randomised 1:1:1:1:1 to bimekizumab 16 mg, 64 mg, 160 mg, 320 mg or placebo every 4 weeks for 12 weeks (double-blind period). At week 12, patients receiving bimekizumab 16 mg, 64 mg or placebo were re-randomised 1:1 to bimekizumab 160 mg or 320 mg every 4 weeks to week 48; other patients continued on their initial dose (dose-blind period). The primary end point was Assessment of SpondyloArthritis international Society (ASAS) 40 response at week 12 (non-responder imputation (NRI) for missing data).

RESULTS

303 patients were randomised: bimekizumab 16 mg (n=61), 64 mg (n=61), 160 mg (n=60), 320 mg (n=61) or placebo (n=60). At week 12, significantly more bimekizumab-treated patients achieved ASAS40 vs placebo (NRI: 29.5%-46.7% vs 13.3%; p<0.05 all comparisons; OR vs placebo 2.6-5.5 (95% CI 1.0 to 12.9)). A significant dose-response was observed (p<0.001). The primary end point was supported by all secondary efficacy outcomes. At week 48, 58.6% and 62.3% of patients receiving bimekizumab 160 and 320 mg throughout the study achieved ASAS40, respectively (NRI); similar ASAS40 response rates were observed in re-randomised patients. During the double-blind period, treatment-emergent adverse events occurred in 26/60 (43.3%) patients receiving placebo and 92/243 (37.9%) receiving bimekizumab.

CONCLUSIONS

Bimekizumab provided rapid and sustained improvements in key outcome measures in patients with active AS, with no unexpected safety findings versus previous studies.

Psoriatic Arthritis: What is Happening at the Joint?

Psoriatic arthritis (PsA) is a heterogeneous and inflammatory disease with diverse clinical manifestations, including psoriasis, nail psoriasis, peripheral joint disease, axial joint disease, enthesitis, and dactylitis. Typically, this varied clinical presentation complicates the clinician's ability to distinguish PsA from other forms of arthritis. In the synovium of individuals with PsA, upregulation of the genes WNT3A, BMPR2, and TGFBR1 results in bone erosion and new bone formation, a pattern unique to the disease. Additionally, genes associated with angiogenesis and vascularization such as VEGF and TGFB1 facilitate inflammation and joint damage. Gross pathogenesis of PsA is driven by proinflammatory cytokines, and key cytokines affecting joint structures include tumor necrosis factor-α, interleukin (IL)-6, IL-17A, IL-21, IL-22, and IL-23. Early diagnosis is critical for providing treatment that prevents irreversible disease progression and function loss. This narrative review discusses differentiation of PsA from other forms of arthritis. Additionally, we detail the role of cytokines at the joint in mediating PsA pathogenesis.Funding: Novartis Pharmaceuticals Corporation.

Minimal Disease Activity and Patient-Acceptable Symptom State in Psoriatic Arthritis: A Real-World Evidence Study With Ustekinumab

BACKGROUND/AIMS

Ustekinumab (UST) is a fully human immunoglobulin G1 monoclonal antibody approved for treating moderate to severe psoriasis and, more recently, psoriatic arthritis (PsA) as well. However, information regarding its clinical usefulness in a real-world setting is scarce. We aimed to evaluate the effectiveness and safety of UST in a real-world clinical setting.

METHODS

This single-center observational study included PsA outpatients (n = 50) treated with UST from March 2015 to March 2017. Only patients who used at least 3 doses of UST were analyzed. The percentage of patients who achieved a minimal disease activity (MDA) response was collected. The impact of the disease was also evaluated according to the recently developed Psoriatic Arthritis Impact of Disease (PsAID) questionnaire. A binary logistic regression multivariate model was performed to look for variables predicting MDA.

RESULTS

Twenty-seven patients (54%) reached an MDA state. Mean PsAID in MDA group was 3.5 ± 2.9 versus 6.8 ± 5.1 in non-MDA patients (p < 0.001). Among the patients who achieved MDA, 19 (70.4%) had a patient-acceptable symptom state according to the PsAID, whereas only 5 (21.7%) of the 23 patients who did not reach an MDA achieved a patient-acceptable symptom state (p < 0.001). Higher basal Psoriasis Area and Severity Index decreased the odds of achieving MDA (odds ratio [OR], 0.80; 95% CI, 0.65-0.99; p = 0.038), whereas a longer use of UST (OR, 1.52; 95% CI, 1.13-2.06; p = 0.015) and a previous failure to 1 anti-tumor necrosis factor α (OR, 18; 95% CI, 2.52-128.63; p = 0.004) increased this odds. We found no major safety problems.

CONCLUSIONS

Ustekinumab was effective and safe in this PsA population. Minimal disease activity and PsAID may be useful tools in the evaluation of PsA therapeutic interventions in routine clinical practice.

Health professional views on the assessment and management of foot problems in people with psoriatic arthritis in Australia and New Zealand: a qualitative investigation

Background

Active foot disease persists in a high proportion of people with psoriatic arthritis despite the availability of pharmacological and non-pharmacological interventions to modify the course of the disease. Limited information exists on the provision of health care for foot disease in psoriatic arthritis. The objective of this study was to explore the views of health professionals on the assessment and management of people with psoriatic arthritis-related foot involvement.

Methods

Convenience sampling was used to recruit health professionals working in rheumatology outpatient clinics in Sydney, Australia and Auckland, New Zealand. Three focus groups were undertaken to explore the views and experiences of health professionals on the assessment and management of foot problems in people with psoriatic arthritis. All interviews were audio-recorded and transcribed verbatim. Qualitative data was analysed using a constant comparative analytic approach to identify themes.

Results

A total of seventeen health professionals participated including rheumatologists, podiatrists and a physiotherapist. Key themes derived from the focus groups suggest that health professionals perceived that people with psoriatic arthritis-related foot problems experience suboptimal management from symptom onset, to diagnosis and treatment. Frustration was expressed throughout discussions relating to lack of appropriate training and expertise required for the specialised management of foot problems typically encountered with psoriatic arthritis and poor access for patients to specialist podiatry services.

Conclusions

This study provides new insight into the perspectives of health professionals on the management of foot problems related to psoriatic arthritis. Deficiencies in the diagnosis, assessment and treatment of foot problems were revealed. To meet the foot health needs of people with psoriatic arthritis, reducing diagnostic delay, improving knowledge and awareness about the disease among people with psoriatic arthritis and health professionals, and increasing specialist podiatry service provision may be required.

[Medical care situation of patients with ankylosing spondylitis and psoriatic arthritis in Germany : Medical care situation of patients with spondyloarthritis (SpA): ankylosing spondylitis (AS) and psoriatic arthritis (PsA) from the perspective of rheumatologists in private practice and hospitals in Germany-Results of the research project "SpA Loop-Life of Outpatients"]

BACKGROUND

The prevalence of spondyloarthritis (SpA) in Germany is approximately 1-1.4% and includes predominantly axial SpA (axSpA) and predominantly peripheral SpA. Ankylosing spondylitis (AS) belongs to the group of axial SpA but also exhibits peripheral manifestations. Psoriatic arthritis (PsA) can show purely peripheral or also axial manifestations. The total prevalence of SpA in Germany is approximately 1‑1.4%, the prevalence of AS is ca. 0.5% and PsA 0.2-1.4%. Patients with AS are mainly treated by internal medical rheumatologists but in many places also basically treated by general practitioners and orthopedists. Patients with PsA are mainly diagnosed and treated by rheumatologists and dermatologists working in private practice or in clinical settings. Besides the control of inflammatory activity and prevention or slowing down of the characteristic disease progression, including irreversible structural changes, the main objectives of patients as well as treating physicians are particularly freedom from pain and a quality of life comparable to non-affected persons. Decisive for successful treatment are an early diagnosis and initiation of adequate therapy as well as regular monitoring of disease activity including treatment adjustment taking the needs of the patient into consideration; however, it is unknown how often this is actually successful in routine daily practice in Germany.

OBJECTIVE

The aim of the SpA Loop research project was to display the current medical care situation of patients with AS and PsA treated in private practices and hospitals for rheumatology in Germany focusing on patient/physician profiles as well as the diagnostics and treatment.

MATERIAL AND METHODS

The instrument for the survey was a standardized questionnaire with 29 multiple choice and perception questions that was distributed to medical specialists in the field of internal medicine and rheumatology.

RESULTS

A high accordance between rheumatologists in private practice and in hospitals was observed with respect to the presentation and perception of the current medical care situation for patients with AS and PsA in Germany. Differences were only occasionally found.

CONCLUSION

The results of this research project reflect the current status of the medical care situation of AS and PsA patients in Germany. They provide information on which areas of the medical care situation can selectively be improved as well as on interesting aspects and points of discussion with respect to the patient population treated.

A Review for Physician Assistants and Nurse Practitioners on the Considerations for Diagnosing and Treating Psoriatic Arthritis

Psoriatic arthritis (PsA) is a clinically heterogeneous form of progressive inflammatory arthritis that affects up to 30% of patients with psoriasis. The rapid rate of progression associated with PsA makes early-disease diagnosis and treatment crucial to patients' quality of life and long-term health. With the aim of providing clinical guidance to physician assistants and nurse practitioners, this article gives an overview of the different PsA clinical domains, including peripheral arthritis, axial disease, enthesitis, dactylitis, skin disease, and nail dystrophy, which should be considered as part of diagnosis and treatment strategies. The efficacy of different therapies across these PsA domains is reviewed within the context of current PsA treatment guidelines while considering more recent data on newly approved therapies for PsA.Funding: Novartis Pharmaceuticals Corp., East Hanover, NJ, USA.

Treatment Patterns Among Patients with Psoriatic Arthritis Treated with a Biologic in the United States: Descriptive Analyses from an Administrative Claims Database

BACKGROUND

In patients with psoriatic arthritis (PsA), limited data exist regarding patterns of biologic therapy use.

OBJECTIVE

To examine treatment patterns and therapy modifications in U.S. patients with PsA receiving a tumor necrosis factor inhibitor (TNFi) or an anti-interleukin (IL)-12/23 inhibitor.

METHODS

Adults with PsA who newly initiated a biologic therapy (index biologic) between January 1, 2013, and January 31, 2015, were included from the Optum Research Database. Biologic therapies comprised those that were approved by the FDA for the treatment of PsA at the time of the study initiation (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab, or ustekinumab). Outcomes included adherence, persistence, and discontinuation of the index biologic; initiation of adjunctive medications (nonbiologics, including those commonly used for pain and/or inflammation); and dose escalation of the index biologic during the 12-month follow-up period.

RESULTS

Of the 1,235 patients included, 52.5% were female, and mean (SD) age was 50.3 (12.1) years. The mean (SD) duration of persistence with a newly initiated index biologic (etanercept [48.1%], adalimumab [24.0%], infliximab [10.4%], golimumab [8.3%], ustekinumab [7.2%], or certolizumab pegol [2.0%]) was 246 (128) days; 44.5% of patients persisted with the index biologic for ≥ 12 months. During the 12-month follow-up period, 22.9% of patients switched to a different biologic, 26.8% discontinued without switching or restarting, and 5.8% discontinued and restarted the index biologic. Of the 1,010 patients who persisted with the index biologic for > 90 days, 45.6% received ≥ 1 adjunctive medication during the period from 90 days after the index date to the end of persistence or 12 months. The most commonly initiated adjunctive medications were corticosteroids (22.0%), opioids (17.1%), and nonsteroidal anti-inflammatory drugs (12.9%). Overall, 9.6% of patients had a dose escalation of the index biologic in the immediate 12-month post-index period.

CONCLUSIONS

This real-world study of treatment patterns for PsA, which used a large U.S. claims database, demonstrated that the majority of patients with PsA discontinued their index biologic (TNFi or anti-IL-12/23 inhibitor) before 12 months. Nearly half of patients initiated an adjunctive medication, many of which were pain and conventional anti-inflammatory medications.

"A body in transformation"-An empirical phenomenological study about fear-avoidance beliefs towards physical activity among persons experiencing moderate-to-severe rheumatic pain

Aims and objectives

To gain a better understanding of fear‐avoidance beliefs towards physical activity and body awareness in people experiencing moderate‐to‐severe rheumatic pain.

Background

Rheumatoid arthritis and psoriatic arthritis are long‐term conditions with pain as the prominent symptom. Health‐promoting physical activity is recommended and can have an analgesic effect. High self‐rated pain has previously been reported to be associated with increased fear‐avoidance behaviour in relation to physical activity. Body awareness, which includes attentional focus and awareness of internal body sensations, could be valuable in the nursing care of long‐term diseases.

Design

Empirical phenomenological.

Methods

An empirical phenomenological psychological method was applied. The interviews took place between autumn 2016–spring 2017 with 11 informants (eight women and three men, age range 44–71 years) who were diagnosed with rheumatoid arthritis (n = 7) or psoriatic arthritis (n = 4), with a disease duration ranging from 3–35 years. The mean visual analogue scale score in the study sample was 60 mm.

Results

Three typologies were identified: “My relatively fragile physical status”, “I am an active creator” and “Part of something bigger than myself.”

Conclusions

The current findings indicated that pain anticipation and fear‐avoidance beliefs towards physical activity sometimes affected the behaviour of individuals with long‐term rheumatic pain syndromes. People experiencing moderate‐to‐severe rheumatic pain tended to focus on their fragile physical and emotional state. By adopting a more favourable attitude towards the self, the body could be restored to a state of calm and balance.

Relevance to clinical practice

The current findings are relevant for healthcare professionals engaged in health‐promotion clinical practice.
