Objectives The AsseSSing Impact in pSoriatic Treatment (ASSIST) study investigated prescribing in routine PsA care and whether the patient-reported outcome—PsA Impact of Disease questionnaire (PsAID-12)—impacted treatment. This study also assessed a range of patient and clinician factors and their relationship to PsAID-12 scoring and treatment modification. Methods Patients with PsA were selected across the UK and Europe between July 2021 and March 2022. Patients completed the PsAID questionnaire and the results were shared with their physician. Patient characteristics, disease activity, current treatment methods, treatment strategies, medication changes and patient satisfaction scores were recorded. Results A total of 503 patients were recruited. Some 36.2% had changes made to treatment, and 88.8% of these had treatment escalation. Overall, the mean PsAID-12 score was higher for patients with treatment escalation; increase in PSAID-12 score is associated with increased odds of treatment escalation (odds ratio 1.58; P < 0.0001). However, most clinicians reported that PsAID-12 did not impact their decision to escalate treatment, instead supporting treatment reduction decisions. Physician’s assessment of disease activity had the most statistically significant effect on likelihood of treatment escalation (odds ratio 2.68, per 1-point score increase). Escalation was more likely in patients not treated with biologic therapies. Additional factors associated with treatment escalation included: patient characteristics, physician characteristics, disease activity and disease impact. Conclusion This study highlights multiple factors impacting treatment decision-making for individuals with PsA. PsAID-12 scoring correlates with multiple measures of disease severity and odds of treatment escalation. However, most clinicians reported that the PsAID-12 did not influence treatment escalation decisions. Psoriatic Arthritis Impact of Disease (PsAID) scoring could be used to increase confidence in treatment de-escalation.

OBJECTIVES:Shared decision-making (SDM) is advocated to improve patient outcomes in PsA. We analysed current prescribing practices and the extent of SDM in PsA across Europe. METHODS:The ASSIST study was a cross-sectional observational study of PsA patients ≥18 years of age attending face-to-face appointments between July 2021 and March 2022. Patient demographics, current treatment and treatment decisions were recorded. SDM was measured by the clinician's effort to collaborate (CollaboRATE questionnaire) and patient communication confidence (PEPPI-5 tool). RESULTS:A total of 503 patients were included from 24 centres across the UK, France, Germany, Italy and Spain. Physician- and patient-reported measures of disease activity were highest in the UK. Conventional synthetic DMARDs constituted a higher percentage of current PsA treatment in the UK than continental Europe (66.4% vs 44.9%), which differed from biologic DMARDs (36.4% vs 64.4%). Implementing treatment escalation was most common in the UK. CollaboRATE and PEPPI-5 scores were high across centres. Of 31 patients with low CollaboRATE scores (<4.5), no patients with low PsAID-12 scores (<5) had treatment escalation. However, of 465 patients with CollaboRATE scores ≥4.5, 59 patients with low PsAID-12 scores received treatment escalation. CONCLUSIONS:Higher rates of treatment escalation seen in the UK may be explained by higher disease activity and a younger cohort. High levels of collaboration in face-to-face PsA consultations suggests effective implementation of the SDM approach. Our data indicate that in patients with mild disease activity, only those with higher perceived collaboration underwent treatment escalation. Prospective studies should examine the impact of SDM on PsA patient outcomes. TRIAL REGISTRATION:clinicaltrials.gov, NCT05171270.

Abstract Background/Aims Psoriatic arthritis (PsA) is a multi-system disease with a range of management options. Treatment may vary by geographic location. We compared disease characteristics and prescribing practices in the UK and Europe in the post-Covid era. Methods The ASSIST study was a cross-sectional observational study of PsA patients aged 18 years and older selected from 24 centres across 5 countries (UK, France, Germany, Italy and Spain) between July 2021 and March 2022 (IRAS: 287039). Patients attending a face-to-face appointment with a diagnosis of PsA made by a rheumatologist were selected by systematic sampling at each centre and treated in routine clinical practice. Patient and disease characteristics, current treatment and treatment decisions (medications unchanged, switched, added or reduced) were recorded. The analysis was descriptive, with no imputation of missing data. Results 503 patients were included, with arthritis subtype, patient age, disease activity and duration shown (Table 1). Physician- and patient-reported disease severity was highest in the UK, where median patient age was lowest. Conventional synthetic (cs) DMARDS constituted a higher percentage of current PsA treatment in UK than continental Europe (66.4% vs 44.9%), whereas biologic use was more frequent in Europe (68.1% vs 36.4%). Adalimumab was the most commonly used biologic in the UK and Spain. Adalimumab and secukinumab were equally used in Germany, and ixekizumab and adalimumab were joint-first in Italy. Implementing change to the current PsA treatment was most common in the UK, predominantly being a treatment increase. This may reflect the higher level of disease activity or younger patient age in the UK than other countries, as treatment escalation is more likely earlier in the disease course. In the UK, treatment escalation was more commonly achieved by medication addition (26.2%) than medication switch (14%) or dose increase (7.5%). In Europe, medication addition and switch were of more similar frequency (10.9% vs 9.85%). Conclusion Disease characteristics and treatment strategies varied between countries, but particularly between UK and the rest of Europe. In contrast to mainland Europe, csDMARDs predominated in the UK, perhaps reflecting current NICE guidelines. Treatment escalation was most common in the UK, in keeping with higher disease activity.

Interleukin-17 family (IL-17s) comprises six structurally related members (IL-17A to IL-17F); sequence homology is highest between IL-17A and IL-17F, displaying certain overlapping functions. In general, IL-17A and IL-17F play important roles in chronic inflammation and autoimmunity, controlling bacterial and fungal infections, and signaling mainly through activation of the nuclear factor-kappa B (NF-κB) pathway. The role of IL-17A and IL-17F has been established in chronic immune-mediated inflammatory diseases (IMIDs), such as psoriasis (PsO), psoriatic arthritis (PsA), axial spondylarthritis (axSpA), hidradenitis suppurativa (HS), inflammatory bowel disease (IBD), multiple sclerosis (MS), and asthma. CD4+ helper T cells (Th17) activated by IL-23 are well-studied sources of IL-17A and IL-17F. However, other cellular subtypes can also produce IL-17A and IL-17F, including gamma delta (γδ) T cells, alpha beta (αβ) T cells, type 3 innate lymphoid cells (ILC3), natural killer T cells (NKT), or mucosal associated invariant T cells (MAIT). Interestingly, the production of IL-17A and IL-17F by innate and innate-like lymphocytes can take place in an IL-23 independent manner in addition to IL-23 classical pathway. This would explain the limitations of the inhibition of IL-23 in the treatment of patients with certain rheumatic immune-mediated conditions such as axSpA. Despite their coincident functions, IL-17A and IL-17F contribute independently to chronic tissue inflammation having somehow non-redundant roles. Although IL-17A has been more widely studied, both IL-17A and IL-17F are overexpressed in PsO, PsA, axSpA and HS. Therefore, dual inhibition of IL-17A and IL-17F could provide better outcomes than IL-23 or IL-17A blockade.

Abstract Background/Aims A personalised approach is required to optimise management of psoriatic arthritis (PsA). Shared decision-making between physician and patient is key, resulting in greater patient satisfaction and outcomes. We assessed the degree of perceived collaboration following clinic visits in the UK and Europe and whether this was associated with treatment escalation. Methods The ASSIST study was a cross-sectional observational study of PsA patients aged 18 years and older selected from 24 centres across 5 countries (UK, France, Germany, Italy and Spain) between July 2021 and March 2022 (IRAS: 287039). Patients attending a face-to-face appointment with a diagnosis of PsA made by a rheumatologist were selected by systematic sampling at each centre and treated in routine clinical practice. Patients completed the collaboRATE questionnaire (scored 0-9), where high scores indicate greater perceived collaboration. The perceived efficacy in patient-physician interactions (PEPPI) tool (scored 5-25) assessed the patients’ view on their confidence in the consultation. Patient, physician, and disease characteristics were recorded, alongside treatment decisions (medications unchanged, switched, added or reduced). The analysis was descriptive, with no imputation of missing data. Results 503 patients were included, with key characteristics shown (Table 1). Generally, the level of disease severity was low (mean total PsAID score 3.6/10) and PEPPI scores were high, indicating patient confidence in the consultation. A subgroup (n = 10) perceived difficulty in sharing their concerns (PEPPI <12/25). However, collaboRATE scores remained high (mean score 7.96), suggesting satisfaction in the physician’s effort to understand patient concerns. Consultation satisfaction was not associated with treatment decisions: mean collaboRATE and PEPPI scores in those with and without treatment escalation were similar. Mean collaboRATE and PsAID scores were not associated. In patients with low collaboRATE scores (<5), only patients with higher PsAID scores (>5) had treatment escalation. However, in patients with high collaboRATE scores, even patients with low PsAID scores had treatment escalation. Conclusion Patients report high levels of shared decision-making in face-to-face PsA consultations, unrelated to treatment escalation. In patients with low PsAID scores, those with higher perceived collaboration are more likely to have treatment escalation than those without, perhaps reflecting the identification of otherwise undetected symptoms/concerns.

Introduction Given the growing interest and use of interleukin-17 inhibitors (anti-IL17) for the treatment of psoriatic arthritis (PsA), an observational study has been conducted to characterize the patient profile, treatment patterns, and persistence of ixekizumab or secukinumab in patients with PsA receiving them as first anti-IL17. Methods This is a multicenter retrospective study, conducted at eight Spanish hospitals where data from adult patients with PsA were collected from electronic medical records. Three cohorts of patients, initiating treatment with an anti-IL17 [secukinumab 150 mg (SECU150), secukinumab 300 mg (SECU300), or ixekizumab (IXE)] between January 2019 and March 2021, were included. Demographic and clinical patient characteristics, treatment patterns, and persistence were analyzed descriptively. Continuous data were presented as mean [standard deviation (SD)] and categorical variables as frequencies with percentages. Persistence rates at 3, 6, and 12 months were calculated. Results A total of 221 patients with PsA were included in the study [SECU150, 103 (46.6%); SECU300, 38 (17.2%); and IXE, 80 (36.2%)]. Treatment patterns differed by clinical characteristics: SECU150 was initiated more frequently in patients with moderate PsA and less peripheral joint involvement, while patients on SECU300 included those with a higher rate of enthesitis and active skin psoriasis, and patients on IXE showed a longer time since PsA diagnosis, more frequent comorbidities, joint involvement, and diagnosed skin psoriasis. Conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) were previously administered in 88.2% of patients and biologic or targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs) were administered in 72.9%. The mean number of previous b/tsDMARDs was 2.4 (SD 1.5) in the IXE cohort, 1.7 (SD 0.9) in the SECU300 cohort, and 1.6 (SD 1.0) for those in the SECU150 cohort. The global persistence on all anti-IL17 was 97.2%, 88.4%, and 81.0% at 3, 6, and 12 months, respectively. The most frequent reason for discontinuation across the three cohorts was lack of effectiveness (16.7%; 37/221). Conclusions Most of the patients with PsA treated with anti-IL17 in Spain had moderate to severe disease activity, high peripheral joint and skin involvement, and had received previous b/tsDMARDs. More than 80% of patients with a 1-year follow-up persisted on anti-IL17, with the highest rate observed in the IXE cohort, followed by the SECU150 then SECU300 cohorts.

Ixekizumab (IXE) is an IgG4-type monoclonal antibody targeting IL-17A indicated alone or in combination with methotrexate, for the treatment of active psoriatic arthritis (PsA) in adult patients with insufficient response or with intolerance to one or more disease-modifying anti-rheumatic drug (DMARD) therapy. The PRO-STIP study aimed to describe persistence, patient characteristics, treatment patterns, and effectiveness in patients with PsA receiving IXE in a real-world clinical setting in Spain. This was an observational, multicentric, retrospective, longitudinal study in adult PsA patients who started IXE between January 2019 and December 2020, with at least 24 weeks of follow-up. A descriptive analysis of patient characteristics and treatment patterns was performed. The primary objective, treatment persistence, was estimated by Kaplan–Meier survival curve. Effectiveness was evaluated by Disease Activity in Psoriatic Arthritis (DAPSA) scores at baseline and at 12 and 24 weeks. Eighty-nine patients met the selection criteria (55.1

Background/Objective Few studies have been published focusing on the differences between juvenile idiopathic inflammatory myopathy (JIIM) and adult IIM. This study aimed to describe the characteristics of JIIM main subgroups (juvenile dermatomyositis [JDM] and juvenile polymyositis [JPM]) and to compare their differences with adult IIM subgroups (adult DM and adult PM). Methods This study reviewed the medical records of patients from the REMICAM cohort, a multicentric longitudinal study carried out in patients with IIM, followed up between 1980 and 2014 in 12 hospitals in Madrid, Spain. Patients with definite or probable JPM, JDM, adult DM, and adult PM according to the modified Bohan and Peter criteria were selected. We compared the characteristics between JDM and JPM, and between JIIM and adult IIM. Results Eighty-six juvenile patients (75 JDMs and 11 JPMs) and 283 adult patients (133 DMs and 150 PMs) were included. Compared with patients with JDM, patients with JPM were older at diagnosis, had more fever and arthritis, and were less frequently treated with disease-modifying antirheumatic drugs (these differences were not statistically significant). Compared with patients with adult DM, those with JDM presented more frequently with calcinosis (33.8% vs 6.9%, p < 0.0001) and had less severe infections (4.3% vs 23.4%, p < 0.0001), malignancies (1.3% vs 25.6%, p < 0.0001), and mortality (3.5% vs 33%, p < 0.0001). Patients with JDM were treated less frequently with azathioprine (10.8% vs 44.7%, p < 0.0001). Conclusions Our findings confirm that JIIMs are a heterogeneous group of diseases with relevant differences compared with adult IIMs.

To establish practical recommendations for the management of patients with psoriatic arthritis (PsA) with particular clinical situations that might lead to doubts in the pharmacological decision-making. A group of six expert rheumatologists on PsA identified particular clinical situations in PsA. Then, a systematic literature review (SLR) was performed to analyse the efficacy and safety of csDMARDs, b/tsDMARDs in PsA. In a nominal group meeting, the results of the SLR were discussed and a set of recommendations were proposed for a Delphi process. A total of 65 rheumatologists were invited to participate in the Delphi. Agreement was defined if ≥ 70% of the participants voted ≥ 7 (from 1, totally disagree to 10, totally agree). For each recommendation, the level of evidence and grade of recommendation was established based on the Oxford Evidence-Based Medicine categorisation. Particular clinical situations included monoarthritis, axial disease, or non-musculoskeletal manifestations. The SLR finally comprised 131 articles. A total of 16 recommendations were generated, all but 1 reached consensus. According to them, it is crucial to carefully analyse the impact of individual manifestations on patients (disability, quality of life, etc.), but also to recognise the impact of each drug singularities on selected clinical phenotypes to adopt the most appropriate treatment strategy. Early diagnosis and treatment to target approach, along with a close risk management, is also necessary. These recommendations are intended to complement gaps in national and international guidelines by helping health professionals address and manage particular clinical situations in PsA.

Objective. Tofacitinib (TOF) is the first Janus kinase (JAK) inhibitor approved for psoriatic arthritis (PsA). It has shown efficacy in patients refractory to anti–tumor necrosis factor-α in randomized controlled trials (RCTs). Our aim was to assess efficacy and safety of TOF in clinical practice. Methods. This was an observational, open-label multicenter study of PsA patients treated with TOF due to inefficacy or adverse events of previous therapies. Outcome variables were efficacy, corticosteroid dose-sparing effect, retention rate, and safety. A comparative study of clinical features between our cohort of patients and those from the OPAL Beyond trial was performed. Results. There were 87 patients (28 women/59 men), with a mean age of 52.8 ± 11.4 years. All patients were refractory to biologic disease-modifying antirheumatic drugs (DMARDs) and/or to conventional synthetic DMARDs plus apremilast. TOF was started at 5 mg twice daily after a mean follow-up of 12.3 ± 9.3 years from PsA diagnosis. At first month, Disease Activity Score in 28 joints based on erythrocyte sedimentation rate (DAS28-ESR) decreased from median 4.8 (IQR 4.1–5.4) to 3.7 (IQR 2.8–4.7, P < 0.01), Disease Activity Index for Psoriatic Arthritis from median 28 (IQR 18.4–34.1) to 15.5 (IQR 10.1–25.7, P < 0.01), and C-reactive protein from median 1.9 (IQR 0.3–5.0) to 0.5 (IQR 0.1–2.2) mg/dL (P < 0.01). Also, TOF led to a significant reduction in prednisone dose. Mild adverse effects were reported in 21 patients (24.13%), mainly gastrointestinal symptoms. TOF retention rate at Month 6 was 77% (95% CI 65.2–86.3). Patients in clinical practice were older with longer disease duration and received biologic agents more commonly than those in the OPAL Beyond trial. Conclusion. Data from clinical practice confirm that TOF seems to be effective, rapid, and relatively safe in refractory PsA despite clinical differences with patients in RCTs.

OBJECTIVES:To describe the methods of the Spanish Registry of patients with idiopathic inflammatory myopathy (IIM) (Myo-Spain), as well as its strengths and limitations. The main objective of the project is to analyse the evolution and clinical management of a cohort of patients with IIM.METHODS:Observational, longitudinal, ambispective and multicentre study of a cohort of patients with IIM seen in rheumatology units in Spain. All patients with a diagnosis of IMM will be included in the regular follow-up of the participating centres, regardless of age on initiation of the process. Incident cases will be all patients who at the beginning of the study have been diagnosed for less than 12 months and prevalent cases for more than 12 months. The registry will include data from the visit at baseline, one year and two years. Socio-demographic, clinical, analytical variables, complications, comorbidities, association with other rheumatic diseases, hospital admissions, mortality and treatments will be collected. In addition, indices, scales and questionnaires of activity, muscle involvement, damage, disability, and quality of life will be determined. The recruitment period will be 23 months. The purpose is to obtain a cohort of 400 patients with IMM.CONCLUSIONS:Myo-Spain registry provides the opportunity to develop a cohort of incident and prevalent patients with IMM in Spain. Myo-Spain will be able to assess in detail the clinical characteristics of the disease at different times. The comprehensive information collected during the visits is expected to provide a broad source of data for future analysis.

Analizar y comparar los cambios en la recogida de variables clínicas tras la implementación en la práctica diaria de un checklist de evaluación para pacientes con espondiloartritis axial (EspAax) y artritis psoriásica (APs). Se realizó un estudio observacional. Mediante revisión de historias médicas, se recogieron el número y el tipo de variables del checklist de evaluación que figuraban en las mismas. La primera revisión se realizó antes de la implementación del checklist, y la segunda, 6 meses después de la implementación (pacientes diferentes) para poder comparar los cambios producidos con la misma. Se realizó un análisis descriptivo y bivariado. Participaron 6 hospitales y 11 reumatólogos. Se revisaron un total de 83 y 68 historias médicas pre- y post-implementación del checklist. Tras la implementación, en la EspAax aumentó significativamente el registro en la historia clínica del consumo de alcohol, diarrea o enfermedad inflamatoria intestinal (EII) y la uretritis, diabetes mellitus, hiperlipidemia, depresión, obesidad o la gota/hiperuricemia, peso, talla, presión arterial, VGM, VGP, BASDAI y DAS28. Y en la APs el consumo de alcohol, HTA, diabetes mellitus, hiperlipidemia, enfermedad, gota/hiperuricemia, expansión torácica, rotación cervical, peso, talla, presión arterial, VGM, VGP, ASDAS, BASDAI y BASFI. Tanto pre- como post-implantación en general existe una tendencia a un mayor porcentaje de recogida de variables en pacientes con EspAax que en pacientes con APs. La implementación de un checklist específico en la práctica diaria mejora la evaluación de los pacientes con EspAax y APs. Se debe seguir trabajando en la mejoría de la evaluación de los pacientes con EspA, pero especialmente en la APs. To analyse and compare changes in the collection of clinical variables after the implementation in daily practice of an evaluation checklist for patients with axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). An observational study was performed based on medical records review. The number and type of variables of the evaluation checklist in the medical records were collected. The first review was made before the implementation of the checklist, and the second one 6 months after the implementation (in different patients). A descriptive and bivariate analysis was carried out. Six hospitals and 11 rheumatologists participated. A total of 83 and 68 medical records were reviewed before and after the implementation of the checklist. After the implementation, in the axSpA patients, a significant increase was recorded in alcohol consumption, diarrhoea or IBD and urethritis, diabetes mellitus, hyperlipidaemia, depression, obesity or gout/hyperuricaemia, weight, height, blood pressure, patient and physician global assessments of disease activity, BASDAI and DAS28. And, in the PsA patients, alcohol consumption, hypertension, diabetes mellitus, hyperlipidaemia, disease, gout/hyperuricaemia, thoracic expansion, cervical rotation, weight, height, blood pressure, patient and physician global assessments of disease, ASDAS, BASDAI, and BASFI were recorded. In general, there was a trend towards greater recording in axSpA compared with PsA. The implementation of a specific checklist in daily practice improves the evaluation of patients with axSpA and PsA. More efforts are necessary to continue improving the evaluation of patients with axSpA, but especially of those with PsA.
