Early Recognition and Treatment Heralds Optimal Outcomes: the Benefits of Combined Rheumatology–Dermatology Clinics and Integrative Care of Psoriasis and Psoriatic Arthritis Patients

Early psoriatic arthritis: clinical and therapeutic challenges

INTRODUCTION

Psoriatic arthritis (PsA) is a chronic immunoinflammatory disease of the enthesis and adjacent synovium, skin, and nail, which early diagnosis may be crucial for starting a prompt therapeutic intervention. Theoretically, early treatment offers the advantage of acting on the reduction of the articular damage progression since initial phases of the disease.

AREAS COVERED

This review explores the challenges of clinical-diagnostic aspects and the underlying pathophysiology of early PsA phases, as well as the evidence evaluating the impact of early intervention on disease outcomes.

EXPERT OPINION

Main instruments for early PsA diagnosis include recognizing synovial-entheseal inflammatory signs at onset, improving screening PsA high-risk subjects, and increasing disease knowledge of physicians and patients with psoriasis or familial history. PsA continues to significantly impact on the Quality of Life of patients affected by the disease, making necessary to deeply study clinical manifestations, risk factors, and underlying immunoinflammatory mechanisms, as well as to identify biomarkers for early identification. Additionally, it remains a need to increase more evidence on understanding how early treatment of PsA and of psoriasis might influence the course of the disease.

Influence of Clinical and Psychosocial Factors on the Adherence to Topical Treatment in Psoriasis

(1) Background: Psoriasis is a common chronic inflammatory skin disease with different manifestations, affecting the quality of life at social, emotional, and professional dimensions and requiring long-term treatment. This study aimed to investigate the effect of psychosocial and clinical factors on adherence to topical treatment in psoriasis. (2) Methods: Self-reported measures and weighing the medicines were used to assess adherence. Psychopathological symptoms were measured using the Brief Symptoms Inventory (BSI). Social and clinical factors were assessed by a sociodemographic and clinical questionnaire. Adherence to treatment with topical medication was assessed using a sample of 102 psoriasis patients. (3) Results: The explanatory models of adherence to topical treatment in psoriasis translated into positive associations between adherence and the education level (higher education) (p = 0.03; φ = 0.23), the single-family household (p = 0.01; φ = 0.44), active employment status (p = 0.05; φ = -0.19), familiar history of psoriasis (p = 0.04; φ = -0.21), and the presence of obsessive-compulsive symptoms (p = 0.01; d = 0.29). (4) Conclusions: In patients who present the characteristics identified that influence non-adherence, instructions should be reinforced to increase adherence. The experimental mortality (39.6%) reduced the sample size, representing a limitation of the study.

The epidemiology of pediatric psoriasis: A nationwide cohort study in Taiwan

Psoriasis can affect individuals of all age groups. While the epidemiology of psoriasis in adults has been extensively studied, there is limited research specifically investigating pediatric cases. This study aimed to investigate the prevalence and incidence of skin psoriasis (PsO) and psoriatic arthritis (PsA) among pediatric patients in Taiwan. A nationwide cohort of 17 535 patients with psoriatic diseases under the age of 18 was enrolled from the National Health Insurance Research Database for the period 2000-2013, including 16 129 PsO patients and 2022 PsA patients. The age- and sex-standardized prevalence and incidence of pediatric PsO and PsA were calculated. The 2007 yearly reports of age- and sex-specific distribution of the general population was adopted as a standard. The results showed that between 2000 and 2013, the prevalence for pediatric PsO increased from 0.03% to 0.07%, and from 0.003% to 0.014% for pediatric PsA. During the same period, the incidence slightly decreased from 19.81 to 17.55 per 100 000 for pediatric PsO but increased from 1.02 to 5.06 per 100 000 for pediatric PsA. Adolescents (12 to <18 years) had higher prevalence and incidence rates of PsO and PsA than children (aged ≤ 12 years), with no sex difference observed in either age group. PsA preceding PsO was more common among children than adolescents (27.07% vs. 13.46%). This study provides important insights into the prevalence and incidence of psoriatic diseases in the pediatric population. Further research is needed to identify risk factors for pediatric psoriasis and to investigate its long-term health outcomes.

A multidisciplinary dermatology-gastroenterology-rheumatology (DER.RE.GA) unit for the care of patients with immune-mediated inflammatory diseases: analysis of the first 5 years from the dermatologist's perspective

Immune-mediated inflammatory diseases (IMIDs) constitute a heterogenous group of chronic and highly disabling conditions. The clinical challenges they often pose led to formation of numerous dermo-rheumatological interdisciplinary units around the world, which are reported to benefit their patients in various ways. The present paper describes our experience with a multidisciplinary dermatology-rheumatology-gastroenterology unit DERREGA at the IRCCS Foundation Policlinico San Matteo of Pavia over a period of 5 years of its activity (2017-2022). A digital database was created, containing the medical records of 146 patients referred to the dermatology unit only by rheumatologists or gastroenterologists belonging to the multidisciplinary unit DERREGA. Then, aspects such as demographics, initial basis of referral and final diagnosis among the patients were analyzed retrospectively. Patients were classified as either gastroenterological or rheumatological, and then categorized according to the specific basis of referral. Most of the gastroenterological patients (97%) were affected by inflammatory bowel diseases (IBDs). Rheumatological patients were divided in three subgroups, including patients referred with vasculitis, arthropathies (undifferentiated arthritis, psoriatic arthritis and other arthritis) and other rheumatological diseases. Then, final diagnoses were evaluated in each group. Almost a third of IBD patients received a diagnosis of paradoxical psoriasis. Dermatological examination allowed diagnosis of minimal psoriasis based on Caspar criteria in over 70% of the patients admitted with undifferentiated arthritis. A multidisciplinary approach is suggested to provide more effective management of IMIDs and, specifically, from a dermatological perspective, allows for the diagnosis of minimal manifestations of psoriasis in patients with a provisional diagnosis of undifferentiated arthritis.

Do Biologic Treatments for Psoriasis Lower the Risk of Psoriatic Arthritis? A Systematic Review

BACKGROUND AND OBJECTIVE

The effectiveness of biologic treatments in slowing the progression of psoriatic arthritis is well established, but there is limited and conflicting evidence on their ability to prevent the development of psoriatic arthritis in patients with psoriasis. The objective of this review was to evaluate the role of biologic treatment for psoriasis in preventing or delaying subsequent psoriatic arthritis.

METHODS

A literature search was performed using MEDLINE (PubMed), Embase, Web of Science, and the Cochrane Library for studies published in English from database inception to March 2022 that statistically compared the risk of psoriatic arthritis in patients aged > 16 years who were previously treated with biologic disease-modifying antirheumatic drugs or with other drugs for skin psoriasis.

RESULTS

Four articles were eligible for analysis, all retrospective cohort studies. Three were conducted in preselected patients attending dermatology or dermatology-rheumatology collaboration centers and one was a large population-based study. In three studies, a primary two-step statistical analysis yielded a significantly lower risk of psoriatic arthritis in patients treated with biologic agents. These findings were not supported by the large retrospective electronic health record-based study.

CONCLUSIONS

Biologic treatments may be effective in preventing the development of psoriatic arthritis in patients with psoriasis. More research is needed given the retrospective cohort design of all studies included in the review limiting the generalizability of the results, and the conflicting results from the registry study. At present, biologic agents should not be prescribed to unselected patients with psoriasis for the sole purpose of preventing psoriatic arthritis.

Screening and Referral Strategies for the Early Recognition of Psoriatic Arthritis Among Patients With Psoriasis: Results of a GRAPPA Survey

OBJECTIVE

This study aimed to explore the experiences of dermatologists and rheumatologists in the early recognition of psoriatic arthritis (PsA) and to identify potential improvements to the current shared-care model.

METHODS

A 24-question survey addressing referral strategies was constructed by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) project steering committee and sent to all members (n = 927). Questions addressed the use of screening tools, frequency of PsA in patients with psoriasis, therapeutic decision making, and suggestions for earlier PsA recognition and current unmet needs.

RESULTS

There were 149 respondents (16.1% response rate), which included 113 rheumatologists from 37 countries and 26 dermatologists from 16 countries. Of the dermatologists, 81% use PsA-specific screening instruments. Conversely, rheumatologists reported that only 26.8% of patients referred to them from all sources had been assessed with screening tools. Although dermatologists reported that a mean of 67% of suspected PsA cases were confirmed, rheumatologists reported a mean of 47.9% of confirmed cases. Both specialties reported similar views regarding optimization of the diagnostic process and indicated that the best approach involved combining patient-reported (ie, screening tools) and physician-confirmed findings. Moreover, both specialties identified the education of primary care physicians (PCPs) and dermatologists as the greatest priority to improve PsA screening.

CONCLUSION

The survey indicated the current unmet needs in the early recognition of PsA. Important areas to address include improving the use of screening instruments, increasing the education of community-based dermatologists and PCPs, and using a combination of patient-reported and physician-confirmed findings in the screening approach.

Periods of psoriatic arthritis onset and diagnosis in Russian patients with moderate to severe psoriasis (according to psoriasis patient registry)

Background: Early detection of psoriatic arthritis in patients with psoriasis remains an unmet medical need. Early diagnosis and treatment initiation in patients with psoriatic arthritis decreases the risk of adverse outcomes and improves patients quality of life. Aims: to describe a period between psoriasis and psoriatic arthritis onset and a period between psoriatic arthritis onset and diagnosis in Russian patients with moderate to severe psoriasis. Materials and methods: analysis of data from the psoriasis patient registry. Patients aged 18 years and older with an established diagnosis of psoriasis and psoriatic arthritis were included in the analysis. Exclusion criteria: no data on timing of psoriatic arthritis onset or diagnosis. Results: sample size for the descriptive characteristic of period between psoriasis and psoriatic arthritis onset was 891 patients; sample size for the descriptive characteristic of period between psoriatic arthritis onset and diagnosis was 849 patients. Psoriatic arthritis onset preceeded cutaneous manifestation of psoriasis in 2.5% of patients. Concurrent onset of cutaneous psoriasis and psoriatic arthritis (within one year) had 10.7% of patients. In 86.8% of patients, cutaneous manifestation of psoriasis preceded manifestation of psoriatic arthritis. Exclusively of patients with psoriatic arthritis developed before or concurrently with cutaneous manifestation of psoriasis, the mean duration of period between psoriasis and psoriatic arthritis onset was 13.7 10.3 years, the median [IQR] 12 [6-19] years. In 24% of patients with psoriatic arthritis the was 1 year or more after its onset. On average, in this subgroup of patients, psoriatic arthritis was diagnosed 3.95.0 years after the signs and/or symptoms onset. Median [IQR] of period between psoriatic arthritis onset and diagnosis was 2 [1-4.5] years. Conclusions: a diagnostic delay in 24% Russian patients with psoriatic arthritis is one year or more. The average delay in diagnosis of psoriatic arthritis is about 4 years.

Patients' Perspectives on Shared Decision-Making About Medications in Psoriatic Arthritis: An Interview Study

OBJECTIVE

Decision-making regarding medications to manage psoriatic arthritis (PsA) is complex because of multiple disease manifestations and comorbidities. Fear of side effects from systemic medications and misalignment in priorities between patients with PsA and rheumatologists makes shared decision-making challenging. We aimed to describe the perspectives of patients with PsA on shared decision-making regarding medication taking.

METHODS

Face-to-face semistructured interviews were conducted with 25 adult patients with PsA in Australia. Transcripts were thematically analyzed.

RESULTS

Five themes were identified: lacking agency in decision-making (denied choice, knowledge asymmetry, desperation and necessity, restricted by unfair eligibility criteria, automated approach); overwhelmed by potential harms (daunted by aggressive therapy, anticipating lifestyle disruption from side effects, jeopardizing fertility and pregnancy, avoiding relapse); gaining confidence (discernible benefit in function and mental health, sharpening knowledge over time, expertise of family and peers, empowered by information); opting for alternatives (pursuing normality, suspicion of over-medicalization, seeking comprehensive solutions); and developing trust and fortifying collaboration (assurance through a personable approach, seeking consistency, supported in decisional power, resolution through respectful negotiation).

CONCLUSION

Patients with PsA lack agency in making treatment decisions and are overwhelmed by the potential harms of systemic medication. Improving knowledge and trust with medical teams in a supportive and collaborative environment, and strategies for managing risks and side effects may improve decision-making about pharmacologic management of PsA.

Multidisciplinary Rheuma–Derma Clinics: 5 Years of Experience at the San Marco Hospital in Catania

Introduction

Early psoriatic arthritis (PsA) diagnosis is critical to prescribe timely treatment to prevent the irreversible joint damage and the many other problems that patients with PsA experience. This retrospective study aimed to highlight the benefits of a Rheuma–Derma Clinic focused on the early diagnosis and prompt treatment of PsA with a shared approach among Italian psoriasis patients. Diagnosing PsA early is the main goal to reduce joint damage and disability in the patients affected. Studies describing the results of rheuma–derma clinics aimed to reach this goal emerged in the last decade. This study presents limitations and advantages typical of retrospective designs.

Methods

A Rheuma–Derma Clinic was created in 2017 at the Rheumatology Department of the Hospital Policlinico Gaspare Rodolico of the University of Catania in San Marco, Italy. This study compared the number of patients under disease-modifying antirheumatic treatment 5 years before and after the joint clinic was created. A rheumatologist and dermatologist simultaneously assessed patients with psoriasis and/or PsA to obtain a rapid multidisciplinary diagnostic approach and a shared therapeutic strategy. In addition, demographic, clinical, and clinimetrics data were collected.

Results

The number of patients with PsA receiving biological disease-modifying antirheumatic drugs increased 47% (from 255 to 374 patients) before and after the joint clinic was implemented. Likewise, those receiving conventional synthetic disease-modifying antirheumatic drugs increased by 47% (from 367 to 539) as well. Additionally, for all the clinimetrics evaluated (DAS28, HAQ, BASDAI, DAPSA, PASI, PGA), there was an improvement over the 12 months under the Rheuma–Derma Clinic care. The measures that improved the most were DAPSA, PGA, PASI, and BASDAI.

Conclusion

The implementation of the Rheuma–Derma Clinic was associated with an increase in the number of patients diagnosed, the number of patients with PsA receiving DMARD treatments, and improvements in clinimetrics among the study participants.

Psoriatic arthritis needs to be detected early to treat it correctly and for its consequences in patients with psoriasis to be prevented. This study was carried out to find out if shared clinics where rheumatologists and dermatologists care for patients together helped to control psoriatic arthritis better and improve the life of the patients affected by it. The shared clinic was created in 2017 at the Rheumatology Department of the Hospital Policlinico Gaspare Rodolico of the University of Catania in San Marco, Italy. The study collected information about the number of patients diagnosed with psoriasis and psoriatic arthritis, the number of patients receiving treatments, and the results of quality of life and other standard tests. During the time that the joint clinic was in place, the number of patients receiving treatments specific for diseases such as psoriatic arthritis increased from 622 (before the clinic was started) to 913. The patients treated in this clinic also had improvements in their quality of life and other aspects. This study found that a clinic where rheumatologists and dermatologists work together to care for patients can increase the number of patients treated with drugs that are specific for their disease and improve their overall health.

A consensus-based approach on the management of patients with both psoriasis and psoriatic arthritis in the dermatological and rheumatological settings in Italy: The ADOI PSO-Amore Project

Psoriasis is a complex disease often needing a multidisciplinary approach. In particular, the collaboration between dermatologist and rheumatologist is crucial for the management of patients suffering from both psoriasis (PSO) and psoriatic arthritis (PsA). Here we report a series of recommendations from a group of experts, as a result of a Consensus Conference, defining the circumstances in which it is preferable or even mandatory, depending on the available settings, to rely on the opinion of the two specialists, jointly or in a deferred manner. Indications are given on how to organize a 3^rd level joint Dermatology- Rheumatology care unit, in connection with 1^st and 2^nd level clinicians of both specialties, GPs, and other specialists involved in the management of psoriasis. A potential patient journey is suggested, that can be used as a basis for future design and validation of national and/or local diagnostic therapeutic and assistance pathways.

Patient and learner experience in a new set up of a multidisciplinary dermatology-rheumatology clinic care model for psoriatic arthritis

OBJECTIVES

We described the set-up of a new multidisciplinary psoriatic arthritis-psoriasis (PsA-PsO) clinic incorporating service, education, and research between rheumatologists and dermatologists for PsA. We describe the patients' and learners' experience of this shared-care model.

METHODS

A PsA-PsO clinic was newly set up in 2019. Each patient was first seen by a trainee, followed by both a dermatologist and a rheumatologist simultaneously in the same consultation room. We collected patients' and learners' experience through self-administered surveys.

RESULTS

From May 2019 to January 2020, we collected data from 44 visits (55% new referrals, 45% follow up) from 30 patients: 22.7% were referred for diagnostic doubts, 77.3% were for therapeutic issues. Eight of the 10 patients referred for diagnosis had PsA confirmed. Medication changes occurred in 63.6% of visits; 63.6% of patients continued follow up in the PsA-PsO clinic, and 36.4% were discharged back to the original respective care. The median (interquartile range) rating of patient satisfaction of the care was 8 (7-8) out of 10; 96.1% of patients would "probably" or "definitely recommend" the care to others. From 20 learners, 95% reported the experience as "extremely" or "very" beneficial to training. The PsA-PsO clinic was suspended during the COVID-19 pandemic from February 2020 because of lack of available staff. The service was resumed gradually from May 2021.

CONCLUSION

Despite challenges, we report the set-up of a new care model between dermatologists and rheumatologists for care of patients with psoriatic disease. The care model was well received by patients. Learners from various levels reported benefit from the learning experience.

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.

Managing Antiphospholipid Syndrome in Children and Adolescents: Current and Future Prospects

Pediatric antiphospholipid syndrome (APS) is a rare acquired multisystem autoimmune thromboinflammatory condition characterized by thrombotic and non-thrombotic clinical manifestations. APS in children and adolescents typically presents with large-vessel thrombosis, thrombotic microangiopathy, and, rarely, obstetric morbidity. Non-thrombotic clinical manifestations are frequently seen in pediatric APS and may be present even before the vascular thrombotic events occur. We review insights into the pathogenesis of APS and discuss potential targets for therapy. The identification of multiple immunologic abnormalities in patients with APS reveals molecular targets for current or future treatment. Management strategies, especially for APS in adolescents, require screening for additional prothrombotic risk factors and consideration of counseling regarding contraceptive strategies, lifestyle recommendations, treatment adherence, and mental health issues associated with this autoimmune thrombophilia. The main goal of therapy in pediatric APS is the prevention of thrombosis. The management of acute thrombosis events in children and adolescents is the same as for primary APS, which involves isolated occurrences, and secondary APS, which is seen in association with another autoimmune disease, e.g., systemic lupus erythematosus. A pediatric hematologist should be consulted so other differential thrombophilic conditions can be eliminated. Therapy includes unfractionated heparin or low-molecular-weight heparin followed by vitamin K antagonists. Treatment of catastrophic APS involves triple therapy (anticoagulation, intravenous corticosteroid pulse therapy, and plasma exchange) and may include intravenous immunoglobulin for children and adolescents with this condition. New drugs such as eculizumab and sirolimus seem to be promising drugs for APS.

Specialized dermatological-rheumatological patient management improves diagnostic outcome and patient journey in psoriasis and psoriatic arthritis: a four-year analysis

Background

Management of psoriasis patients with arthralgia suffering from suspected psoriatic arthritis (PsA) requires an interdisciplinary approach involving dermatologists and rheumatologists. The aim of the study was to analyze the specialized dermatological-rheumatological management of these patients before and after foundation of a PsA center.

Methods

A retrospective cohort study of all dermatological-rheumatological consultations during two periods was conducted. Period one, from April 1st, 2016 to February 28th, 2018 versus period two, from March 1st, 2018 to January 31st, 2020, after foundation of a PsA center. Clinical data on patient characteristics including psoriasis subtypes, clinical symptoms and signs, disease activity scores, classification criteria and comorbidities as well as patient journey were extracted and analyzed.

Results

Four hundred four consultations were studied. Close collaboration in a PsA center lead to a relevantly shortened patient journey concerning rheumatological complaints: period 1: median (IQR): 36.0 (10.0–126.0) months, period 2: median (IQR): 24.0 (6.0–60.0) months. Established scores and classification criteria such as GEPARD or CASPAR did not assist in diagnosis of PsA. Arthralgia (p = 0.0407), swollen joints (p = 0.0151), morning stiffness (p = 0.0451) and dactylitis (p = 0.0086) helped to distinguish between osteoarthritis and PsA.

Conclusions

Clinical signs and symptoms, scores and classification criteria usually assessed were less helpful than expected in diagnosis of PsA. Close collaboration in a specialized PsA center yielded the fastest way of diagnosis.

Development of a digital toolkit to improve quality of life of patients with systemic lupus erythematosus

Objective

The purpose of this manuscript is to detail development and initial usability testing of an e-toolkit designed to provide skills and knowledge around self-management behaviors for individuals living with systemic lupus erythematosus.

Methods

Researchers worked with a steering committee of patients and providers to (1) develop a clickable prototype of an e-toolkit and (2) conduct alpha (individuals not affiliated with an academic clinic as patient or provider) and beta (individual patients with systemic lupus erythematosus as well as members of the clinic healthcare team and individuals who work in patient advocacy organizations) usability testing through semistructured interviews.

Results

During the review of the e-toolkit, the feedback provided by participants in both alpha and beta groups centered on two overarching themes: (1) improving user interface and materials and (2) integration of information and supports between toolkit and clinical personnel.

Conclusion

Digital approaches that are tailored to individual symptom variation and integrated with a clinical system have the opportunity to enhance ongoing clinical care. These findings support movement toward integrated, team-based care models, tailored digital resources, and use of expanded virtual interaction options to ensure on-going engagement between healthcare providers and systemic lupus erythematosus patients.

"Reuma-Check": Performance of a Comprehensive Fast-Track Program for the Diagnosis of Axial Spondyloarthritis in South America

OBJECTIVES

The aim of this study was to evaluate the performance of a comprehensive diagnosis program called "Reuma-check" for the diagnosis of axial spondyloarthritis (SpA) in patients with low back pain (LBP).

METHODS

This is a cross-sectional study. Patients with LBP aged 18 years or older were preselected, and those with at least 1 SpA feature completed the circuit. They were referred after 2 strategies: education for orthopedists and a campaign on social networks. All patients underwent a clinical evaluation, laboratory testing, and imaging (including human leukocyte antigen B27 evaluation and magnetic resonance imaging). The diagnosis of axial SpA was established by an expert rheumatologist opinion. Time from onset of symptoms to "Reuma-check," time from patient referral to admission of the checkup, and time from "Reuma-check" to diagnosis were evaluated.

RESULTS

A total of 175 of 246 patients were included, most of them came from the social media campaign (55%). Seventy-five (43%) of 175 patients were diagnosed as axial SpA. The median time from referral (or self-referral) to access to the program was 1.3 months. The median time from symptoms onset to access to the program was 31.7 months, and the median time from the performance of "Reuma-check" to final diagnosis was 2 weeks. Features associated with a diagnosis of axial SpA were as follows: inflammatory LBP (odds ratio [OR], 6.64; 95% confidence interval [CI], 1.6-28), clinical enthesopathy (OR, 4.56; 95% CI, 1.1-18.4), positive human leukocyte antigen B27 (OR, 23.02; 95% CI, 3.5-58), and positive magnetic resonance imaging (OR, 14.34; 95% CI, 3.5-58).

CONCLUSIONS

"Reuma-check" allowed a high frequency of axial SpA diagnosis and improved access to rapid diagnosis, shortening the time from referral to diagnosis with a shorter acquisition time for the ancillary studies. Patients with a final diagnosis of axial SpA presented distinctive features.

Unmet needs in psoriatic arthritis

Psoriatic arthritis (PsA) is a chronic inflammatory arthritis with a highly variable clinical presentation that does not have a validated molecular or imaging test, making accurate diagnosis a challenge. Consequences of diagnostic delay include irreversible joint damage and significant morbidity. Over the past few decades, there have been major advances in the understanding and treatment of PsA, leading to more targeted therapies. However, there is no current method to predict optimal treatment strategy to achieve minimal disease activity and prevent medication-related adverse events in the management of early disease. PsA is also associated with other comorbidities that include metabolic syndrome and psychosocial burden; two areas that are often unaddressed in the clinical setting and have associated sequelae. This chapter focuses on key domains of unmet needs, which include diagnostic challenges, delay in diagnosis, prognostication systems and stratified medicine approaches and precision medicine strategies for established and emerging therapies.

A 12-point recommendation framework to support advancement of the multidisciplinary care of psoriatic arthritis: A call to action

OBJECTIVE

Making a differential diagnosis of psoriatic arthritis (PsA) is not straightforward. This is partly because of its heterogeneous presentation and partly because many patients with PsA are initially diagnosed with psoriasis and treated in primary care or by dermatologists, with referral to rheumatologists being delayed. Once diagnosed, optimal disease control requires frequent specialist monitoring, adjustment or switching of therapies, and management of comorbidities and concomitant diseases, as well as attention to patients' overall well-being. Given the breadth of expertise that diagnosis and management of PsA requires, we sought to define a collaborative, structured framework that supports the optimisation of multidisciplinary care for patients with PsA in Europe.

METHODS

An expert panel comprising four rheumatologists, three dermatologists, two specialist nurses and one psychologist-from Spain, the United Kingdom, The Netherlands, Germany, France and Italy-met face-to-face to take part in a modified Delphi exercise.

RESULTS

The result of this exercise is a set of recommendations that are based on combining published evidence with the panel's extensive clinical experience. Recommendations can be implemented in a number of ways, but the central call-to-action of this framework is the need for improved collaboration between dermatologists (or primary care physicians) and rheumatologists. This could occur in a variety of different formats: standard referral pathways, multidisciplinary physician meetings to discuss patient cases, or 'one stop', combined clinics.

CONCLUSION

We anticipate that when the majority of patients with PsA receive regular multidisciplinary care, improved patient outcomes will follow, although robust research is needed to explore this assumption.

Recommendations for psoriatic arthritis management: A joint position paper of the Taiwan Rheumatology Association and the Taiwanese Association for Psoriasis and Skin Immunology

In Taiwan, the incidence and prevalence of psoriatic arthritis (PsA) have risen significantly in recent years. Moreover, data from the Taiwan National Health Insurance Research Database (NHIRD) show that more than 85% of PsA patients are treated with just non-steroidal anti-inflammatory drugs (NSAIDs) and/or conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs). Taiwanese clinicians have also expressed concerns regarding uncertainties in the diagnosis of PsA and the delayed, interrupted, and/or tapered use of biologics, as well as differences in therapeutic preferences between and within dermatologists and rheumatologists. To address these issues, the Taiwan Rheumatology Association and the Taiwanese Association for Psoriasis and Skin Immunology jointly convened a committee of 28 clinicians from the fields of rheumatology, dermatology, orthopedics, and rehabilitation, to develop evidence-based consensus recommendations for the practical management of PsA in Taiwan. A total of six overarching principles and 13 recommendations were developed and approved, as well as a treatment algorithm with four separate tracks for axial PsA, peripheral PsA, enthesitis, and dactylitis. Psoriasis (PsO) management was not discussed here, as the Taiwanese Dermatological Association has recently published a comprehensive consensus statement on the management of PsO. Together, these recommendations provide an up-to-date, evidence-based framework for PsA care in Taiwan.

LOOP, a cross-sectional, observational study investigating the clinical specialty setting as a determinant of disease management in psoriatic arthritis: Subgroup analysis results from Japan

Background

Psoriatic arthritis (PsA) is a progressive erosive joint disorder that causes functional impairment; therefore, early diagnosis and management are essential. This study evaluated the association between clinical specialty and the time to management in patients with PsA in Japan.

Methods

This was a subgroup analysis of a cross-sectional, multicenter, observational study that was conducted in 17 countries outside the United States, including 17 sites at 8 institutions in Japan, from June 2016 to October 2017. Data from consecutive patients (age ≥18 years) with a suspected or established diagnosis of PsA on a routine visit to a participating rheumatology/orthopedic or dermatology clinic in Japan were analyzed. The primary endpoints were time from onset of inflammatory musculoskeletal symptoms to PsA diagnosis, PsA diagnosis to first conventional synthetic disease-modifying antirheumatic drug (csDMARD), PsA diagnosis to first biologic DMARD (bDMARD), and first csDMARD to first bDMARD.

Results

Of 109 patients with a confirmed diagnosis of PsA, 39.4% (n = 43) and 60.6% (n = 66) were recruited by rheumatologists/orthopedists and dermatologists, respectively. Most patients were prescribed tumor necrosis factor inhibitors (58.7%) or methotrexate (56.0%). The mean duration from symptom onset to PsA diagnosis was significantly longer (p = 0.044) for patients treated by rheumatologists/orthopedists (70.6 months) than those treated by dermatologists (30.1 months). In the rheumatology/orthopedic and dermatology settings, the mean time from PsA diagnosis to first csDMARD administration was −0.9 and −2.9 months, and from PsA diagnosis to first bDMARD 21.4 and 14.9 months, respectively. The mean duration from administration of first csDMARD to first bDMARD was comparable in the rheumatology/orthopedic (31.8 months) and dermatology (31.5 months) settings.

Conclusions

Treatment approach was slightly different between rheumatology/orthopedic and dermatology setting in clinical practice in Japan, suggesting that an integrated dermo-rheumatologic approach can optimize the management of patients with PsA.

Multidisciplinary working in the management of axial and peripheral spondyloarthritis

Multidisciplinary (MD) care is essential in the management of patients with spondyloarthritis (SpA) and is one of the main pillars of disease management and patient care. However, evidence supporting the effectiveness and benefits of this strategy in SpA is scarce. In this review we discuss the three types of MD care models: (i) combined clinics (MD units), including ‘face to face’, ‘parallel’ and ‘circuit approach’ clinics; (ii) MD team meetings; (iii) group consultations. The most frequently used model in SpA studies has been the ‘parallel’ combined clinic and usually encompasses a rheumatologist and another specialist, most commonly a dermatologist or a gastroenterologist, that work in tandem according to predefined referral criteria and treatment algorithms. MD working seems to improve the care of patients with SpA by a better identification and diagnosis of the disease, an earlier and more comprehensive treatment approach, and better outcomes for patients in terms of disease activity, physical function, quality of life and patient satisfaction. Nevertheless, challenges remain. Data on effectiveness and feasibility are scarce and are mostly derived from studies with design issues and often without a unidisciplinary care comparator arm. Although patient centricity is one of the core values of patient care and MD setting in SpA, the patient often does not play an active role in most of the MD settings studied or in common clinical practice. Further efforts should be made so that MD care reflects patients’ expectations and needs. Overcoming these limits will help to implement successfully SpA MD care in daily clinical practice and subsequently to achieve a higher quality of care for our patients.

Clinicians' perspectives of shared care of psoriatic arthritis and psoriasis between rheumatology and dermatology: an interview study

OBJECTIVE

Shared care between rheumatologists and dermatologists is advocated for patients with psoriasis and psoriatic arthritis, but care provided by rheumatologists and dermatologists is often siloed, leading to inconsistencies in patient care and outcomes. This study aimed to describe rheumatologists' and dermatologists' perspectives on shared care.

METHODS

Face-to-face semi-structured interviews were conducted with 15 rheumatologists and 12 dermatologists across 27 centers in Australia. Transcripts were thematically analyzed.

RESULTS

Five themes were identified: uncertainties in disciplinary tensions (lacking expertise to make diagnosis, hesitation managing outside of scope, doubting screening tools, defaulting to own disciplinary priorities, hampered by lack of evidence), working in fragmented care (frustration with working in silos, striving to coordinate with primary care, persevering despite inequities in access to care, overwhelmed by managing comorbidities, under-resourced for complexity), building trusting relationships (establishing a culture of collaboration, seeking reliable cross-specialty help, depending on unique skills), prioritizing efficiency (minimizing burden for patients, avoiding resource overuse, deferring to pragmatic decisions), and strengthened by integrated care models (improving the timeliness and accuracy of care, centering on patient goals and understanding, enhancing cross-specialty partnerships, providing opportunities for education and training).

CONCLUSIONS

Rheumatologists and dermatologists endeavor to provide comprehensive care to their patients in disjointed healthcare settings but are hampered by a lack of training and a sense of feeling overburdened in the management of comorbidities. Interdisciplinary models are perceived to improve the care of patients but are limited by financial barriers to implementation and concerns about wasting health resources and improperly burdening patients. Key Points • Rheumatologists and dermatologists perceive that shared care models improve the care for their patients with psoriatic arthritis and psoriasis by improving the timeliness and accuracy of management, making the patient the center of care, and enhancing shared care relationships between specialties. • Screening tools to detect psoriatic arthritis may be under-utilized by dermatologists due to doubt about the accuracy of instruments and competing priorities in time-limited consultations. • Management of comorbid disease is challenging for rheumatologists and dermatologists due to a need to prioritize their specialty area and a sense of feeling overburdened while working in fragmented healthcare systems.

Anti-TNF biosimilars in rheumatology: the end of an era?

INTRODUCTION

Tumor necrosis factor inhibitors (TNFi) have revolutionized the treatment of rheumatic diseases. Whilst extremely efficacious, the original TNFi also carried a high acquisition cost that limited their use. 'Biosimilar' TNFi's, developed on expiry of the patents for the biooriginators, have comparable efficacy and safety, are less expensive and provide the potential to improve access to these effective therapies in a more cost-effective manner.

AREAS COVERED

The background and development of TNFis, their biosimilars and follow on 'copycat' drugs are discussed, together with their use in both developed and developing countries, focusing on the potential to enhance access to effective targeted therapies.

EXPERT OPINION

Bridging the economic gap to facilitate universal access to anti-TNF biosimilars has been largely unsuccessful, driving the development of copycat mimics in developing countries. Meanwhile, the more recent introduction of targeted synthetic disease-modifying drugs has provided cheaper, equally effective treatments for rheumatic diseases that are conveniently delivered by mouth. We review the TNF biosimilars in rheumatic diseases, their role in a rapidly evolving treatment landscape, and speculate about the future for this iconic therapeutic class.

How does the joint dermatology-rheumatology clinic benefit both patients and dermatologists?

Psoriasis (Pso) and psoriatic arthritis (PsA) are chronic and debilitating diseases which often develop in the same patient and are linked to a wide range of comorbid conditions. Dermatologists and rheumatologists need to cooperate in combined clinics, especially when they deal with severe, recalcitrant disease, and multiple comorbidities. The clinical and research benefits of this collaboration have been previously described to contribute to a better and more sustainable health care system. To apply a more holistic approach of patients with Pso and PsA, we established the first dual care clinic in Greece, for Pso and PsA patients, based at Attikon General University Hospital. Hereby, we describe the infrastructure and operation of a combined Pso and PsA clinic (PPAC), in the national health care system of Greece, and its impact on the management of Pso and PsA. The PPAC is a single-day joint clinic, held once a week, which consists of three dermatologists and three rheumatologists. We present the results of 185 newly diagnosed patients between December 2018 and January 2019. Mean age of onset of Pso was 34 ± 16 years old and 47 ± 12 years old for PsA. Most patients suffered from severe plaque Pso (144/185, 78%) and asymmetric oligoarticular arthritis (59/185, 32%), for which they were receiving treatment with biologic agents (105/185, 57%). Many required monitoring for hypertension (74/185, 40%), dyslipidemia (69/185, 37%), diabetes (17/185, 9%), and depression (20/185, 11%). Patients reported high levels of care satisfaction (visual analogue scale: 86 ± 11.5), using the PPAC facility, compared to different referrals between specialties. This is the first joint dermatology-rheumatology clinic in Greece, providing comprehensive care in patients with Pso and PsA. Our results support the concept of combined clinics delivering better integrated care for such patients.

Improving the standard of care for patients with spondyloarthritis-related immune inflammatory conditions: results of a Delphi study and proposal for early detection

Background

Our objective was to provide consensus recommendations on the optimal management of the immune-mediated inflammatory diseases (IMIDs) seen in patients with spondyloarthritis (SpA) using a multidisciplinary approach, and to develop a simple tool to help earlier recognition and referral of coexisting IMIDs in patients who already have one type of IMID.

Methods

A total of 28 experts in the multidisciplinary management of the SpA-associated IMIDs assessed two questionnaires: one with statements focused on the multidisciplinary management of IMIDs, and a second questionnaire focused on questions useful for early recognition and referral. Panelists assessed the statements with a 9-point ordinal scale (1 = strongly disagree, 9 = strongly agree) using a modified Delphi methodology.

Results

Consensus was reached on 72 out of the 82 statements (87.8%). Panelists agreed that the multidisciplinary approach to IMIDs is not sufficiently developed. The creation of multidisciplinary IMID units might be necessary. These units might focus primarily on patients with two or more coexisting IMIDs, or on IMIDs that are especially complex from a diagnostic or therapeutic point of view. Specialists who attend to patients with IMIDs should perform a screening for other coexisting IMIDs. A simple tool to help earlier recognition and referral of coexisting IMIDs is proposed.

Conclusions

There is a need to improve care for patients with SpA-associated IMIDs. We provide expert recommendations to guide the adoption of a multidisciplinary approach for these cases, and a simple tool that may be useful for earlier recognition of coexisting IMIDs.

Strategies to Improve Outcomes in Psoriatic Arthritis

PURPOSE OF REVIEW

The therapeutic response to biologic agents in psoriasis is significantly higher than observed in psoriatic arthritis (PsA). In this review, specific actions to improve treatment outcomes in PsA are discussed.

RECENT FINDINGS

Increased understanding of disease pathogenesis derived from improved preclinical models and advances in cell-based and molecular technologies provide new tools to identify therapeutic targets. In addition to the important contributions of metabolic comorbidities, chronic pain and the lack of a diagnostic biomarker signal the need for new strategies to improve outcomes. Potential strategies include the following: (1) discover a novel pathway or cellular subset, (2) apply stratification biomarkers to individualize therapy, (3) preclinical intervention, (4) combination therapy, (5) lifestyle modification, (6) address chronic pain and fatigue, and (7) multidisciplinary care. The future holds great promise for enhanced treatment responses in PsA based on improved understanding of individual variation in disease pathophysiology coupled with comprehensive and integrated treatment programs.

[Improvement of prognosis by timely treatment : Requirement: initial presentation within 6 weeks]

Rheumatoid arthritis (RA) is one of the most frequent chronic inflammatory rheumatic diseases and when untreated leads to chronic tissue destruction and increased mortality. Due to innovative systemic treatment strategies established over the last 20-25 years, the prognosis has considerably improved in terms of disease and socioeconomic burdens, symptoms, long-term prognosis, ability to work and mortality; however, as a rule a prerequisite is long-term and continuous treatment. A medicinal cure of RA is still not in view. For many patients this means the long-term use of very expensive medications. In addition to hemato-oncology, rheumatology has become the second most expensive discipline in Germany in terms of cost per patient. Convincing data from many studies imply that an early start of treatment within the first few weeks after clinical onset of symptoms improves the prognosis, reduces the necessity for expensive drugs and thereby considerably decreases medical costs. This results in the requirement that every patient with symptoms of arthritis must be seen by a rheumatologist within the first 6 weeks following initial manifestation of the disease. Such an improvement in treatment can only be achieved in Germany if the numbers of rheumatologists and trained healthcare professionals in practices such as clinics are considerably increased. This is not only in the interests of patients but also in the interests of the health insurance companies because the investment in the healthcare infrastructure with internistic rheumatologists will result in substantial economic benefits for the cost bearer. It must be the common task of all players in healthcare policy, cost bearers and internistic rheumatologists to provide optimal conditions in medical as well as economical terms.

Multidisciplinary Management of Psoriatic Arthritis: The Benefits of a Comprehensive Approach

Psoriatic arthritis (PsA) is a lifelong disease associated with extra-articular manifestations and several comorbidities, as well as reduced quality of life and psychosocial burden. Diagnostic delay is associated with poorer outcomes, while a short delay between symptom onset and diagnosis is linked with preservation of function. Overcoming the barriers to early diagnosis of PsA is often difficult to achieve in the absence of well-characterized disease markers and/or a definitive screening procedure. Once a diagnosis is made, approaches to care may differ between countries, but a treat-to-target approach can be advocated, with constant patient follow-up visits and specialist monitoring and treatment of comorbidities. Adequately addressing all aspects of care can help to drive patient-centered care and encourage better adherence. Given the mounting number of therapeutic options and the complexity of management of PsA, the disease can be optimally treated by a multidisciplinary approach, and a collaborative approach between rheumatologists and dermatologists can be advocated. The need for multidisciplinary management is reinforced by consensus among experts. Patient satisfaction has emerged as a central indicator of quality, and patient-centered care must remain a central goal for the care of patients with PsA. Definition of a minimum set of standards for care will help to achieve the goal of multidisciplinary care for patients with PsA. Optimal care of PsA and greater collaboration among clinicians should always be encouraged so that patients can receive the best possible quality of care.Funding: Pfizer Italy.
