Anxiety and depression symptoms in adolescents and young adults with juvenile idiopathic arthritis: results of an outpatient screening

BACKGROUND

Previous studies have shown that growing up with rheumatic conditions can fuel dissatisfaction and psychological distress, which in turn affects disease self-management and treatment adherence. Primary objective of this study was to estimate the prevalence of anxiety and depression symptoms in adolescents and young adults (AYA) with juvenile idiopathic arthritis (JIA) and to identify correlates of conspicuous screening results.

METHODS

Initiated as part of the COACH multicenter observational study, outpatients aged 12 to 21 years participating in the National Pediatric Rheumatological Database (NPRD) were prospectively screened for mental health using the Patient Health Questionnaire-9 (PHQ-9) and the Generalised Anxiety Disorder Scale-7 (GAD-7).

RESULTS

Data from 1,150 adolescents with JIA (mean age 15.6 ± 2.2 years; mean disease duration 7.2 ± 4.9 years, 69% female, 43% oligoarthritis, 26% polyarthritis) were analysed. Overall, 32.7% (n = 316) of AYA showed conspicuous screening results, of whom 30.4% reported clinically relevant suicidal or self-harm thoughts. About 19% of screened patients showed moderate to severe depressive or anxious symptoms. AYA with conspicuous screening results were older (15.8 vs. 15.2 years; p < 0.0001), more often female (81% vs. 64%; p < 0.0001) and more often overweight (25% vs. 17%; p = 0.006). They had higher disease activity (physician global assessment on NRS 0-10; 1.7 vs. 1.2; p < 0.0001), more functional limitations (CHAQ; 0.44 vs. 0.14; <0.0001) and rated their health status worse (NRS 0-10; 3.5 vs. 1.8; p < 0.0001) than AYA with inconspicuous screening results. Females (OR 2.33 [CI 1.53-3.56]; p < 0.0001), older age (OR 1.09 [CI 1.01-1.18]; p = 0.026), patients with more functional limitations (OR 3.36 [CI 1.98-5.72]; p < 0.0001), and patients with worse subjective health status (OR 1.17 [CI 1.07-1.27]; p < 0.0001) were more likely to have a conspicuous screening result. Regular sports participation was associated with a lower likelihood of conspicuous screening result (OR 0.69 [CI 0.49-0.98]; p = 0.039).

CONCLUSIONS

A large-scale outpatient screening of AYA with JIA in Germany shows a high prevalence of anxiety and depression symptoms. The need for routine screening for early detection of mental health problems became apparent.

A practical approach to uveitis screening in children with juvenile idiopathic arthritis

BACKGROUND

Juvenile idiopathic arthritis (JIA)-associated uveitis typically presents as a silent chronic anterior uveitis and can lead to blindness. Adherence to current screening guidelines is hampered by complex protocols which rely on the knowledge of specific JIA characteristics. The Multinational Interdisciplinary Working Group for Uveitis in Childhood identified the need to simplify screening to enable local eye care professionals (ECPs), who carry the main burden, to screen children with JIA appropriately and with confidence.

METHODS

A consensus meeting took place in January 2023 in Barcelona, Spain, with an expert panel of 10 paediatric rheumatologists and 5 ophthalmologists with expertise in paediatric uveitis. A summary of the current evidence for JIA screening was presented. A nominal group technique was used to reach consensus.

RESULTS

The need for a practical but safe approach that allows early uveitis detection was identified by the panel. Three screening recommendations were proposed and approved by the voting members. They represent a standardised approach to JIA screening taking into account the patient's age at the onset of JIA to determine the screening interval until adulthood.

CONCLUSION

By removing the need for the knowledge of JIA categories, antinuclear antibody positivity or treatment status, the recommendations can be more easily implemented by local ECP, where limited information is available. It would improve the standard of care on the local level significantly. The proposed protocol is less tailored to the individual than the 'gold standard' ones it references and does not aim to substitute those where they are being used with confidence.

Best clinical practice in the treatment of juvenile systemic sclerosis: expert panel guidance - the result of the International Hamburg Consensus Meeting December 2022

INTRODUCTION

Juvenile systemic sclerosis (jSSc) is an orphan disease with a prevalence of 3 in 1,000,000 children. Currently there is only one consensus treatment guideline concerning skin, pulmonary and vascular involvement for jSSc, the jSSc SHARE (Single Hub and Access point for pediatric Rheumatology in Europe) initiative, which was based on data procured up to 2014. Therefore, an update of these guidelines, with a more recent literature and expert experience, and extension of the guidance to more aspects of the disease is needed.

AREAS COVERED

Treatment options were reviewed, and opinions were provided for most facets of jSSc including general management, some of which differs from adult systemic sclerosis, such as the use of corticosteroids, and specific organ involvement, such as skin, musculoskeletal, pulmonary, and gastroenterology.

EXPERT OPINION

We are suggesting the treat to target strategy to treat early to prevent cumulative disease damage in jSSc. Conclusions are derived from both expert opinion and available literature, which is mostly based on adult systemic sclerosis (aSSc), given shared pathophysiology, extrapolation of results from aSSc studies was judged reasonable.

[Validation of the total morbidity score and investigation of the efficacy of methotrexate in localized scleroderma]

BACKGROUND

Localized scleroderma is an autoimmune disease belonging to the group of collagenoses, which can manifest cutaneously and extracutaneously. The extracutaneous manifestations may have significant morbidity but are not considered in previous scoring systems. For this reason, another scoring system, the total morbidity score (TMS) was developed, which also takes into account the extracutaneous symptoms.

METHOD

In the retrospective monocentric study at the Hamburg Center for Pediatric and Adolescent Rheumatology, the TMS was applied to patients from 2004-2019 suffering from localized scleroderma who had at least one control presentation. In addition, data were analyzed according to the previously established localized scleroderma cutaneous assessment tool (LoSCAT) scoring systems to ensure better comparability to the TMS. Furthermore, the score values were considered and compared during the course of treatment with methotrexate (MTX).

RESULTS

Due to a lack of control presentations, data from 51 of the 95 patients with a confirmed diagnosis could be included in the retrospective evaluation. The treatment of these patients was considered over a period of 2 years, from the initial presentation over at least 3 further control presentations. The TMS total score remained largely constant. There was a weak correlation between the TMS total score and the localized scleroderma skin damage index (mLoSDI), which indicates the degree of damage. In addition, insignificant changes in the TMS total score were shown over time with MTX treatment (T1/T4: -0.007).

DISCUSSION

The evaluation showed that the TMS total score is mainly fed by the extracutaneous manifestations, demonstrating the inaccuracy of previous scores. Another advantage of the TMS is that different scores are assigned depending on whether the feature is new, persistent, improving, or even worsening. The TMS is more time consuming to collect but enables a more accurate assessment of disease activity.

Level and correlates of physical activity among children and adolescents with juvenile idiopathic arthritis compared to controls: results from a German nationwide prospective observational cohort study

BACKGROUND

Physical active lifestyles are essential throughout growth and maturation and may offer potential preventive and therapeutic benefit in patients with juvenile idiopathic arthritis (JIA). Insufficient physical activity (PA), in contrast, can lead to aggravation of disease-related symptoms. This study aimed to i) examine PA levels in children and adolescents with JIA compared to general population controls and ii) investigate correlates of pronounced physical inactivity in order to identify risk groups for sedentary behaviour.

METHODS

Data from children and adolescents with JIA and population controls aged 3 to 17 years documented in the National Pediatric Rheumatologic Database (NPRD) and the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) were used. Self-reported PA was collected from parents/guardians of children up to 11 years of age or adolescents 12 years of age and older. To compare PA-related data, age- and sex-specific pairwise analyses were conducted considering NPRD/KiGGS participants' data from 2017. Correlates of physical inactivity among patients were identified using a linear regression model.

RESULTS

Data of 6,297 matched-pairs (mean age 11.2 ± 4.2 years, female 67%, patients' disease duration 4.5 ± 3.7 years, persistent oligoarthritis 43%) were available for evaluation. Almost 36% of patients aged 3-17 years (vs. 20% of controls) achieved the WHO recommended amount of PA, while PA steadily decreased with age (18% of patients aged ≥ 12 years) and varied between JIA categories. Female adolescents and patients with enthesitis-related arthritis were least likely to achieve the minimum recommended level of PA. Physical inactivity was associated with female sex, higher age at disease onset, longer disease duration, more functional disability (C-HAQ) and higher disease activity (cJADAS-10).

CONCLUSIONS

Depending on JIA category, children and adolescents with JIA were similarly or even more likely to achieve the WHO recommended minimum level of PA compared to general population controls. However, since a large proportion of young JIA patients appear to be insufficiently physically active, engagement in targeted efforts to promote PA is urgently needed.

Consensus statement on the diagnosis and treatment of sclerosing diseases of the skin, Part 1: Localized scleroderma, systemic sclerosis and overlap syndromes

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present consensus provides an update to the 2017 European Dermatology Forum Guidelines, focusing on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, updated strategies for the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 1 of this consensus provides clinicians with an overview of the diagnosis and treatment of localized scleroderma (morphea), and systemic sclerosis including overlap syndromes.

Consensus statement on the diagnosis and treatment of sclerosing diseases of the skin, Part 2: Scleromyxoedema and scleroedema

The term 'sclerosing diseases of the skin' comprises specific dermatological entities, which have fibrotic changes of the skin in common. These diseases mostly manifest in different clinical subtypes according to cutaneous and extracutaneous involvement and can sometimes be difficult to distinguish from each other. The present consensus provides an update to the 2017 European Dermatology Forum Guidelines, focusing on characteristic clinical and histopathological features, diagnostic scores and the serum autoantibodies most useful for differential diagnosis. In addition, updated strategies for the first- and advanced-line therapy of sclerosing skin diseases are addressed in detail. Part 2 of this consensus provides clinicians with an overview of the diagnosis and treatment of scleromyxoedema and scleroedema (of Buschke).

How should we approach management of childhood onset chronic anterior uveitis refractory to adalimumab?

INTRODUCTION

The management of refractory juvenile idiopathic associated uveitis (JIAU) or childhood-onset chronic anterior uveitis (CAU) is a challenge. There is no clear consensus or evidence base for to suggest the most appropriate therapy after primary or secondary failure of biweekly adalimumab. In this scenario, most clinicians advocate switching to another anti-tumor necrosis factor alpha inhibitor; however, there are a variety of other disease modifying agents to choose from albeit with a differing levels of evidence.

AREAS COVERED

We discuss how to define nonresponse and potential treatment options for patients with JIAU and CAU refractory to biweekly adalimumab.

EXPERT OPINION

Uncontrolled CAU and JIAU remain one of the most challenging diseases to manage and can lead to irreversible loss of vision in a third of those affected. Amongst the possible choices, weekly adalimumab, infliximab, tocilizumab and abatacept have more evidence to support their use. JAK inhibitors seem to be a promising option. Golimumab and Rituximab has also been thought to be partially effective in some refractory cases, whereas IL-17, IL-23, and IL-12 inhibition along with apremilast seem not to be a therapeutic option currently. The route of administration should also be considered as there can be significant pros and cons for different children.

Long-term safety and effectiveness of canakinumab in patients with monogenic autoinflammatory diseases: results from the interim analysis of the RELIANCE registry

OBJECTIVE

Interim analysis of the RELIANCE registry, an on-going, non-interventional, open-label, multicentre, prospective study evaluating the long-term safety, dosing regimens and effectiveness of canakinumab in patients with cryopyrin-associated periodic syndromes (CAPS), familial Mediterranean fever (FMF), tumour-necrosis factor receptor-associated periodic syndrome (TRAPS) or mevalonate-kinase deficiency (MKD)/hyperimmunoglobulin-D syndrome (HIDS).

METHODS

From September 2017 for patients with CAPS, and June 2018 for patients with FMF, TRAPS or MKD/HIDS, the registry enrolled paediatric (aged ≥2 years) and adult patients (aged ≥18 years) receiving canakinumab as part of their routine medical care. Safety, canakinumab dose, disease activity and quality of life outcome measures were evaluated at baseline and every 6 months until end of study visit.

RESULTS

At the analysis cut-off date (December 2020), 168 patients (91 CAPS, 54 FMF, 16 TRAPS and 7 MKD/HIDS) were enrolled. 85 (50.9%) patients were female and 72 (43.1%) were children (<18 years). The median patient age was 20.0 years (range 2.0-79.0 years). In the CAPS cohort, serious infections and serious adverse drug-reactions were more common in patients receiving higher than the recommended starting dose (SD) of canakinumab. A trend to receive >SD of canakinumab was observed in the pooled population. The majority of patients were reported as having either absent or mild/moderate disease activity (physician's global assessment) from baseline to Month 30, with a stable proportion of patients (~70%) in remission under canakinumab treatment. Patient-reported disease activity (Visual Analogue Scale (VAS), Autoinflammatory Disease Activity Index), fatigue (VAS); markers of inflammation (C-reactive protein, serum amyloid A and erythrocyte sedimentation rate) remained well-controlled throughout.

CONCLUSION

Data from this analysis confirm the long-term safety and effectiveness of canakinumab for the treatment of CAPS, FMF, TRAPS and MKD/HIDS.

Safety and effectiveness of abatacept in juvenile idiopathic arthritis: results from the PRINTO/PRCSG registry

OBJECTIVE

To report the interim 5-year safety and effectiveness of abatacept in patients with juvenile idiopathic arthritis (JIA) in the PRINTO/PRCSG registry.

METHODS

The Abatacept JIA Registry (NCT01357668) is an ongoing observational study of children with JIA receiving abatacept; enrolment started in January 2013. Clinical sites enrolled patients with JIA starting or currently receiving abatacept. Eligible patients were assessed for safety (primary end point) and effectiveness over 10 years. Effectiveness was measured by clinical 10-joint Juvenile Arthritis Disease Activity Score (cJADAS10) in patients with JIA over 5 years. As-observed analysis is presented according to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

RESULTS

As of 31 March 2020, 587 patients were enrolled; 569 are included in this analysis (including 134 new users) with 1214.6 patient-years of safety data available. Over 5 years, the incidence rate (IR) per 100 patient-years of follow-up of serious adverse events was 5.52 (95% confidence interval [CI]: 4.27, 7.01) and of events of special interest was 3.62 (95% CI: 2.63, 4.86), with 18 serious infections (IR 1.48 [95% CI: 0.88, 2.34]). As early as month 3, 55.9% of patients achieved cJADAS10 low disease activity and inactive disease (20.3%, 72/354 and 35.6%, 126/354, respectively), sustained over 5 years. Disease activity measures improved over 5 years across JIA categories.

CONCLUSION

Abatacept was well tolerated in patients with JIA, with no new safety signals identified and with well-controlled disease activity, including some patients achieving inactive disease or remission.

Ten-year safety and clinical benefit from open-label etanercept treatment in children and young adults with juvenile idiopathic arthritis

OBJECTIVES

CLIPPER2 was an 8-year, open-label extension of the phase 3b, 2-year CLIPPER study on the safety and efficacy of etanercept in patients with JIA, categorized as extended oligoarticular arthritis (eoJIA), enthesitis-related arthritis (ERA) or PsA.

METHODS

Participants with eoJIA (2-17 years old), ERA or PsA (each 12-17 years old) who received ≥1 etanercept dose (0.8 mg/kg weekly; maximum 50 mg) in CLIPPER could enter CLIPPER2. Primary end point was occurrence of malignancy. Efficacy assessments included proportions achieving JIA ACR 30/50/70/90/100 criteria and ACR inactive disease criteria, and clinical remission (ACR criteria) or Juvenile Arthritis DAS (JADAS) ≤1.

RESULTS

Overall, 109/127 (86%) CLIPPER participants entered CLIPPER2 [n = 55 eoJIA, n = 31 ERA, n = 23 PsA; 99 (78%) on active treatment]; 84 (66%) completed 120 months' follow-up [32 (25%) on active treatment]. One malignancy (Hodgkin's disease in 18-year-old patient with eoJIA treated with methotrexate for 8 years) was reported; there were no cases of active tuberculosis or deaths. Numbers and incidence rates (events per 100 patient-years) of TEAEs (excluding infections/ISRs) decreased from 193 (173.81) in Year 1 to 9 (27.15) in Year 10; TE infections and serious infections also decreased. Over 45% of participants (n = 127) achieved JIA ACR50 responses from Month 2 onwards; 42 (33%) and 34 (27%) participants achieved JADAS and ACR clinical remission, respectively.

CONCLUSIONS

Etanercept treatment up to 10 years was well tolerated, consistent with the known safety profile, with durable response in the participants still on active treatment. The benefit-risk assessment of etanercept in these JIA categories remains favourable.

Proposed Response Parameters for Twelve-Month Drug Trial in Juvenile Systemic Sclerosis: Results of the Hamburg International Consensus Meetings

OBJECTIVE

Juvenile systemic sclerosis (SSc) is an orphan disease, associated with high morbidity and mortality. New treatment strategies are much needed, but clearly defining appropriate outcomes is necessary if successful therapies are to be developed. Our objective here was to propose such outcomes.

METHODS

This proposal is the result of 4 face-to-face consensus meetings with a 27-member multidisciplinary team of pediatric rheumatologists, adult rheumatologists, dermatologists, pediatric cardiologists, pulmonologists, gastroenterologists, a statistician, and patients. Throughout the process, we reviewed the existing adult data in this field, the more limited pediatric literature for juvenile SSc outcomes, and data from 2 juvenile SSc patient cohorts to assist in making informed, data-driven decisions. The use of items for each domain as an outcome measure in an open label 12-month clinical trial of juvenile SSc was voted and agreed upon using a nominal group technique.

RESULTS

After voting, the domains agreed on were global disease activity, skin, Raynaud's phenomenon, digital ulcers, musculoskeletal, cardiac, pulmonary, renal, and gastrointestinal involvement, and quality of life. Fourteen outcome measures had 100% agreement, 1 item had 91% agreement, and 1 item had 86% agreement. The domains of biomarkers and growth/development were moved to the research agenda.

CONCLUSION

We reached consensus on multiple domains and items that should be assessed in an open label, 12-month clinical juvenile SSc trial as well as a research agenda for future development.

Long-Term Maintenance of Clinical Responses by Individual Patients With Polyarticular-Course Juvenile Idiopathic Arthritis Treated With Abatacept

OBJECTIVE

To investigate the frequency and trajectories of individual patients with polyarticular-course juvenile idiopathic arthritis (JIA) achieving novel composite end points on abatacept.

METHODS

Data from a clinical trial of subcutaneous abatacept (NCT01844518) and a post hoc analysis of intravenous abatacept (NCT00095173) in patients with polyarticular-course JIA were included. Three end points were defined and evaluated: combined occurrence of low disease activity (LDA) measured by the Juvenile Arthritis Disease Activity Score; 50% improvement in American College of Rheumatology criteria for JIA (ACR50); and patient-reported outcomes. Patient-reported outcomes included visual analog scale score of minimal pain (pain-min) and Childhood Health Assessment Questionnaire disability index score of 0 (C-HAQ DI0). In this post hoc analysis, maintenance of month 13 and 21 end points (LDA+pain-min, LDA+C-HAQ DI0, and ACR50+pain-min) in those who achieved them at month 4 was determined.

RESULTS

Composite end points (LDA+pain-min, LDA+C-HAQ DI0, and ACR50+pain-min) were achieved at month 4 (44.7%, 19.6%, and 58.9% of the 219 patients treated with subcutaneous abatacept, respectively). Of those who achieved LDA+pain-min at month 4, 84.7% (83 of 98) and 65.3% (64 of 98) maintained LDA+pain-min at months 13 and 21, respectively. The proportions of patients meeting LDA+pain-min outcomes increased from 44.7% (98 of 219) at month 4 to 54.8% (120 of 219) at month 21. The frequency of patients who met an LDA+C-HAQ DI score of 0 increased from 19.6% (43 of 219) at month 4 to 28.8% (63 of 219) at month 21.

CONCLUSION

Among individual patients with polyarticular-course JIA treated with abatacept who achieved 1 of the combined clinical and patient-reported outcomes composite end points, many maintained them over 21 months of abatacept treatment.

Application and performance of disease activity indices proposed for patients with systemic sclerosis in an international cohort of patients with juvenile systemic sclerosis

Objectives

Juvenile systemic sclerosis is a rare childhood disease. Three disease activity indices have been published for adult patients with systemic sclerosis: the European Scleroderma Study Group Index, a modified version of the European Scleroderma Study Group Index and the revised European Scleroderma Trials and Research index. The objective of this study was to determine the feasibility and performance of the three disease activity indices in a prospectively followed cohort of patients with juvenile systemic sclerosis.

Methods

The analysis cohort was selected from the prospective international inception cohort enrolling juvenile systemic sclerosis patients. The correlation of the disease activity indices with the physicians' and the patients' global assessment of disease activity was determined. The disease activity indices were compared between patients with active and inactive disease. Sensitivity to change between 6- and 12-month follow-up was investigated by mixed models.

Results

Eighty percent of the 70 patients had a diffuse cutaneous subtype. The revised European Scleroderma Trials and Research index was highly correlated with the physician-reported global disease activity/parents-reported global disease activity (r = 0.74/0.64), followed by the European Scleroderma Study Group activity index (r = 0.61/0.55) and the modified version of the European Scleroderma Study Group activity index (r = 0.51/0.43). The disease activity indices significantly differed between active and inactive patients. The disease activity indices showed sensitivity to change between 6- and 12-month follow-up among patients who improved or worsened according to the physician-reported global disease activity and the parents-reported global disease activity.

Conclusion

Overall, no disease activity score is superior to the other, and all three scores have limitations in the application in juvenile systemic sclerosis patients. Furthermore, research on the concept of disease activity and suitable scores to measure disease activity in patients with juvenile systemic sclerosis is necessary in future.

Baricitinib in juvenile idiopathic arthritis: an international, phase 3, randomised, double-blind, placebo-controlled, withdrawal, efficacy, and safety trial

BACKGROUND

Juvenile idiopathic arthritis can be refractory to some or all treatment regimens, therefore new medications are needed to treat this population. This trial assessed the efficacy and safety of baricitinib, an oral Janus kinase 1/2-selective inhibitor, versus placebo in patients with juvenile idiopathic arthritis.

METHODS

This phase 3, randomised, double-blind, placebo-controlled, withdrawal, efficacy, and safety trial was conducted in 75 centres in 20 countries. We enrolled patients (aged 2 to <18 years) with polyarticular juvenile idiopathic arthritis (positive or negative for rheumatoid factor), extended oligoarticular juvenile idiopathic arthritis, enthesitis-related arthritis, or juvenile psoriatic arthritis, and an inadequate response (after ≥12 weeks of treatment) or intolerance to one or more conventional synthetic or biologic disease-modifying antirheumatic drugs (DMARDs). The trial consisted of a 2-week safety and pharmacokinetic period, a 12-week open-label lead-in period (10 weeks for the safety and pharmacokinetic subcohort), and an up to 32-week placebo-controlled double-blind withdrawal period. After age-based dosing was established in the safety and pharmacokinetic period, patients received a once-daily 4 mg adult-equivalent dose of baricitinib (tablets or suspension) in the open-label lead-in period. Patients meeting Juvenile Idiopathic Arthritis-American College of Rheumatology (JIA-ACR) 30 criteria (JIA-ACR30 responders) at the end of the open-label lead-in (week 12) were eligible for random assignment (1:1) to receive placebo or continue receiving baricitinib, and remained in the double-blind withdrawal period until disease flare or up to the end of the double-blind withdrawal period (week 44). Patients and any personnel interacting directly with patients or sites were masked to group assignment. The primary endpoint was time to disease flare during the double-blind withdrawal period and was assessed in the intention-to-treat population of all randomly assigned patients. Safety was assessed in all patients who received at least one dose of baricitinib throughout the three trial periods. For adverse events in the double-blind withdrawal period, exposure-adjusted incidence rates were calculated. The trial was registered on ClinicalTrials.gov, NCT03773978, and is completed.

FINDINGS

Between Dec 17, 2018 and March 3, 2021, 220 patients were enrolled and received at least one dose of baricitinib (152 [69%] girls and 68 [31%] boys; median age 14·0 years [IQR 12·0-16·0]). 219 patients received baricitinib in the open-label lead-in period, of whom 163 (74%) had at least a JIA-ACR30 response at week 12 and were randomly assigned to placebo (n=81) or baricitinib (n=82) in the double-blind withdrawal period. Time to disease flare was significantly shorter with placebo versus baricitinib (hazard ratio 0·241 [95% CI 0·128-0·453], p<0·0001). Median time to flare was 27·14 weeks (95% CI 15·29-not estimable) in the placebo group, and not evaluable for patients in the baricitinib group (<50% had a flare event). Six (3%) of 220 patients had serious adverse events during the safety and pharmacokinetic period or open-label lead-in period. In the double-blind withdrawal period, serious adverse events were reported in four (5%) of 82 patients (incidence rate [IR] 9·7 [95% CI 2·7-24·9] per 100 patient-years at risk) in the baricitinib group and three (4%) of 81 (IR 10·2 [2·1-29·7]) in the placebo group. Treatment-emergent infections were reported during the safety and pharmacokinetic or open-label lead-in period in 55 (25%) of 220 patients, and during the double-blind withdrawal period in 31 (38%) of 82 (IR 102·1 [95% CI 69·3-144·9]) in the baricitinib group and 15 (19%) of 81 (IR 59·0 [33·0-97·3]) in the placebo group. Pulmonary embolism was reported as a serious adverse event in one patient (1%; IR 2·4 [95% CI 0·1-13·3]) in the baricitinib group in the double-blind withdrawal period, which was judged to be related to study treatment.

INTERPRETATION

Baricitinib was efficacious with an acceptable safety profile in the treatment of polyarticular juvenile idiopathic arthritis, extended oligoarticular juvenile idiopathic arthritis, enthesitis-related arthritis, and juvenile psoriatic arthritis, after inadequate response or intolerance to standard therapy.

Systemic therapy in juvenile localized scleroderma

INTRODUCTION

Juvenile localized scleroderma (JLS) is a rare sclerosing disorder of childhood which can result in permanent morbidity and functional disability, if not effectively treated. Treatment should be started in the inflammatory phase before the development of any complication and/or damage.

AREAS COVERED

In this review, we will discuss how to assess disease activity and damage in JLS, and propose an escalation plan for systemic treatment, according to a treat-to-target concept. We will discuss the definition of inactive disease and how and when to discontinue medications.

EXPERT OPINION

Before starting treatment, it is extremely important to assess baseline disease activity for treatment response to be adequately checked. Moreover, the activity of the extra cutaneous involvement is an important part of the assessment. Patients should be treated in the 'therapeutic window,' before significant fibrosis results. Most patients should receive systemic treatments; in these patients, Methotrexate should be used as the first-line disease-modifying anti-rheumatic drug (DMARD). However, methotrexate intolerance or non-response is an issue, and these patients should be proposed a treatment escalation according to results of latest studies. Future research can develop better prognostic markers to help to guide our decision.

Gender differences in juvenile systemic sclerosis patients: Results from the international juvenile scleroderma inception cohort

Objective

To compare organ involvement and disease severity between male and female patients with juvenile onset systemic sclerosis.

Methods

Demographics, organ involvement, laboratory evaluation, patient-reported outcomes and physician assessment variables were compared between male and female juvenile onset systemic sclerosis patients enrolled in the prospective international juvenile systemic sclerosis cohort at their baseline visit and after 12 months.

Results

One hundred and seventy-five juvenile onset systemic sclerosis patients were evaluated, 142 females and 33 males. Race, age of onset, disease duration, and disease subtypes (70% diffuse cutaneous) were similar between males and females. Active digital ulceration, very low body mass index, and tendon friction rubs were significantly more frequent in males. Physician global assessment of disease severity and digital ulcer activity was significantly higher in males. Composite pulmonary involvement was also more frequent in males, though not statistically significantly. After 12 months, they are the pattern of differences changed female patients had significantly more frequent pulmonary involvement.

Conclusion

In this cohort, juvenile onset systemic sclerosis had a more severe course in males at baseline and but the pattern changed after 12 months. Some differences from adult findings persisted, there is no increased signal of pulmonary arterial hypertension or heart failure in male pediatric patients. While monitoring protocols of organ involvement in juvenile onset systemic sclerosis need to be identical for males and females.

Adherence, helpfulness and barriers to treatment in juvenile idiopathic arthritis - data from a German Inception cohort

OBJECTIVES

To develop and evaluate German versions of the Parent Adherence Report Questionnaire (PARQ) and Child Adherence Report Questionnaire (CARQ) and to evaluate adherence in patients with juvenile idiopathic arthritis (JIA).

METHODS

The PARQ and CARQ were translated into German, cross-culturally adapted and administered to patients (age ≥ 8 years) and their parents enrolled in the Inception Cohort Study of newly diagnosed JIA patients (ICON). The psychometric issues were explored by analyzing their test-retest reliability and construct validity.

RESULTS

Four hundred eighty-one parents and their children with JIA (n = 465) completed the PARQ and CARQ at the 4-year follow-up. Mean age and disease duration of patients were 10.1 ± 3.7 and 4.7 ± 0.8 years, respectively. The rate of missing values for PARQ/CARQ was generally satisfactory, test-retesting showed sufficient reliability. PARQ/CARQ mean child ability total scores (0-100, 100 = best) for medication were 73.1 ± 23.3/76.5 ± 24.2, for exercise: 85.6 ± 16.5/90.3 ± 15.0, for splints: 72.9 ± 24.2/82.9 ± 16.5. Construct validity was supported by PARQ and CARQ scores for medications, exercise and splints showing a fair to good correlation with the Global Adherence Assessment (GAA) and selected PedsQL scales. Adolescents showed poorer adherence than children. About one third of the parents and children reported medication errors. Perceived helpfulness was highest for medication, and adverse effects were reported the greatest barrier to treatment adherence.

CONCLUSIONS

The German versions of the PARQ and CARQ appear to have a good reliability and sufficient construct validity. These questionnaires are valuable tools for measuring treatment adherence, identifying potential barriers and evaluating helpfulness of treatments in patients with JIA.

Approach to Systemic Sclerosis Patient Assessment

Systemic sclerosis (SSc) is a heterogeneous disease comprising of a wide spectrum of ages of onset, sex-based differences, ethnic variations, disease manifestations, differential serologic profiles, and variable response to therapy resulting in reduced health-related quality of life, disability, and survival. The ability to subset groups of patients with SSc can assist with refining the diagnosis, guide appropriate monitoring, inform aggressiveness of immunosuppression, and predict prognosis. The ability to subset patients with SSc has several important practical implications for patient care.

Secukinumab in enthesitis-related arthritis and juvenile psoriatic arthritis: a randomised, double-blind, placebo-controlled, treatment withdrawal, phase 3 trial

BACKGROUND

Treatment options in patients with enthesitis-related arthritis (ERA) and juvenile psoriatic arthritis (JPsA) are currently limited. This trial aimed to demonstrate the efficacy and safety of secukinumab in patients with active ERA and JPsA with inadequate response to conventional therapy.

METHODS

In this randomised, double-blind, placebo-controlled, treatment-withdrawal, phase 3 trial, biologic-naïve patients (aged 2 to <18 years) with active disease were treated with open-label subcutaneous secukinumab (75/150 mg in patients <50/≥50 kg) in treatment period (TP) 1 up to week 12, and juvenile idiopathic arthritis (JIA) American College of Rheumatology 30 responders at week 12 were randomised 1:1 to secukinumab or placebo up to 100 weeks. Patients who flared in TP2 immediately entered open-label secukinumab TP3 that lasted up to week 104. Primary endpoint was time to disease flare in TP2.

RESULTS

A total of 86 patients (median age, 14 years) entered open-label secukinumab in TP1. In TP2, responders (ERA, 44/52; JPsA, 31/34) received secukinumab or placebo. The study met its primary end point and demonstrated a statistically significant longer time to disease flare in TP2 for ERA and JPsA with secukinumab versus placebo (27% vs 55%, HR, 0.28; 95% CI 0.13 to 0.63; p<0.001). Exposure-adjusted incidence rates (per 100 patient-years (PY), 95% CI) for total patients were 290.7/100 PY (230.2 to 362.3) for adverse events and 8.2/100 PY (4.1 to 14.6) for serious adverse events in the overall JIA population.

CONCLUSIONS

Secukinumab demonstrated significantly longer time to disease flare than placebo in children with ERA and JPsA with a consistent safety profile with the adult indications of psoriatic arthritis and axial spondyloarthritis.

Medication burden in young adults with juvenile idiopathic arthritis: data from a multicentre observational study

OBJECTIVE

To assess the medication and disease burden of young adults with juvenile idiopathic arthritis (JIA).

METHODS

Young adults with JIA prospectively followed in the Juvenile Arthritis Methotrexate/Biologics long-term Observation reported on their health status and medication use. All medications taken (disease-modifying antirheumatic drugs (DMARDs)/prescription/over-the-counter drugs, but excluding most local therapies) classified according to the Anatomical Therapeutic Chemical Classification System were included in this analysis. Medication use at last follow-up was evaluated by sex, JIA category and time from symptom onset to the first biological DMARD (bDMARD) start.

RESULTS

A total of 1306 young adults (68% female) with JIA and a mean disease duration of 13.6±6 years were included in the study. Patients reported using on average 2.4±2.1 medicines and 1.5±1.7 non-DMARD medicines, respectively, at the last follow-up. Almost a quarter of the patients reported polypharmacy. The higher the number of medications used was, the higher the disease activity, pain and fatigue, and the lower the quality of life of patients. Medication usage differed significantly between sexes and JIA categories, being highest in patients with rheumatoid factor-positive polyarthritis and systemic JIA. The number of medications used was significantly associated with the time from symptom onset to bDMARD start. Patients taking opioids or antidepressants had a particularly high disease burden and had received bDMARDs an average of 2 years later than patients not taking these medications.

CONCLUSION

Medication use in adults with JIA varies depending on sex, JIA category, and the time between symptom onset and initiation of treatment with bDMARD.

Biologics with or without methotrexate in treatment of polyarticular juvenile idiopathic arthritis: effectiveness, safety and drug survival

OBJECTIVE

To investigate the impact of additionally given methotrexate (MTX) on biologic treatment of polyarticular juvenile idiopathic arthritis (JIA) in terms of effectiveness, safety and drug survival.

METHODS

Patients suffering from polyarticular JIA and treated with either monotherapy with a first biologic or a combination of a biologic and MTX were selected from the BIKER registry. The tumour necrosis factor α-inhibitors (TNFi) adalimumab, etanercept and golimumab and the interleukin-6 inhibitor tocilizumab were considered. Upon a non-randomised study design, we adjusted the different cohorts using propensity score matching to improve comparability.

RESULTS

A total of 2148 patients entered the analysis, who were either treated by combination (n = 1464) or monotherapy (n = 684). Disease activity declined significantly greater in patients upon combination therapy than upon biologic monotherapy. Comparison of adjusted cohorts revealed that patients who received TNFi gained more benefit from additionally given MTX than patients treated with tocilizumab. Median survival time of therapy with biologics was significantly longer upon combination (3.1 years) than with monotherapy (2.7 years), as demonstrated by a Kaplan-Meier analysis (log rank test: p= 0.002). The safety profile was moderately affected by additional MTX due to increased incidence of gastrointestinal and hepatic adverse events. Serious adverse events occurred at an equal rate of 3.6 events per 100 patient-years in both cohorts.

CONCLUSION

Additionally given MTX improves the effectiveness of biologic treatment in polyarticular JIA without seriously compromising treatment safety. Especially TNFi benefit from combination, while no improvement in outcome has been observed by combining tocilizumab with MTX.

Standardised nailfold capillaroscopy in children with rheumatic diseases: a worldwide study

OBJECTIVES

To standardly assess and describe nailfold videocapillaroscopy (NVC) assessment in children and adolescents with juvenile rheumatic and musculoskeletal diseases (jRMD) versus healthy controls (HC).

METHODS

In consecutive jRMD children and matched HC from 13 centres worldwide, 16 NVC images per patient were acquired locally and read centrally per international consensus standard evaluation of the EULAR Study Group on Microcirculation in Rheumatic Diseases. 95 patients with juvenile idiopathic arthritis (JIA), 22 with dermatomyositis (JDM), 20 with systemic lupus erythematosus (cSLE), 13 with systemic sclerosis (jSSc), 21 with localized scleroderma (lSc), 18 with mixed connective tissue disease (MCTD) and 20 with primary Raynaud's phenomenon (PRP) were included. NVC differences between juvenile subgroups and HC were calculated through multivariable regression analysis.

RESULTS

A total number of 6474 images were assessed from 413 subjects (mean age 12.1-years, 70.9% female). The quantitative NVC-characteristics were significantly lower (↓) or higher (↑) in the following subgroups compared to HC: For density: ↓ in jSSc, JDM, MCTD, cSLE and lSc; For dilations: ↑ in jSSc, MCTD and JDM; For abnormal shapes: ↑ JDM and MCTD; For haemorrhages: ↑ in jSSc, MCTD, JDM and cSLE. The qualitative NVC-assessment of JIA, lSc and PRP did not differ from HC, whereas the cSLE and jSSc, MCTD, JDM, cSLE subgroups showed more non-specific and scleroderma patterns respectively.

CONCLUSION

This analysis resulted from a pioneering registry of NVC in jRMD. The NVC-assessment in jRMD differed significantly from HC. Future prospective follow up will further elucidate the role of NVC in jRMD.

POS0220 LONG-TERM SAFETY AND EFFECTIVENESS OF CANAKINUMAB IN CRYOPYRIN-ASSOCIATED PERIODIC SYNDROMES – 36-MONTH DATA FROM THE RELIANCE REGISTRY

Background

The cryopyrin-associated periodic fever syndromes (CAPS) are hereditary monogenic autoinflammatory diseases with severe systemic and organ inflammation due to increased production of Interleukin-1β (IL-1β). The subcutaneously administered monoclonal antibody canakinumab (CAN) effectively inhibits IL-1β and results in rapid remission of CAPS symptoms in clinical trials as well as in real-life.

Objectives

The RELIANCE registry is designed to explore long-term safety and effectiveness of CAN under routine clinical practice conditions in pediatric (≥2 years) and adult patients with CAPS, including Muckle-Wells syndrome (MWS), familial cold autoinflammatory syndrome (FCAS), and neonatal onset multisystem inflammatory disease (NOMID)/chronic infantile neurological cutaneous and articular syndrome (CINCA).

Methods

This prospective, non-interventional, observational study with a 3-year follow-up enrolls patients in Germany with clinically confirmed diagnoses of CAPS routinely receiving CAN. In 6-monthly visits, clinical data, physician assessments and patient-reported outcomes are evaluated starting at baseline.

Results

98 CAPS patients (52% female; 15 [15%] NOMID/CINCA subtypes) were enrolled by December 2021 (Table 1). At baseline, median age was 20 years and median duration of prior CAN treatment was 6 years. At the 36 months visit, 74% of patients reached disease remission by physicians´ assessment along with increasing rates of absent disease activity (patient’s assessment, median 2.0 at baseline and 0.0 month 36). In addition, patients reported low levels of fatigue (absent to mild/moderate: 87% at baseline and 95% at month 36). At baseline, CAPS impaired social life in 47% of patients (37% at month 36) and 33% (23% at month 36) reported days off from school/work. Lab parameters were within normal limits. Remission and disease control were sustained as evaluated parameters remained stable or even decreased over time.

POS1374 LONG-TERM SAFETY OF CANAKINUMAB IN PATIENTS WITH AUTOINFLAMMATORY DISEASES - INTERIM ANALYSIS OF THE RELIANCE REGISTRY

Background

Autoinflammatory diseases (AID) are characterized by severe systemic and organ inflammation as well as high burden of disease for patients and their families. Treatment with the monoclonal antibody canakinumab (CAN), an interleukin-1β inhibitor, has been proven to be safe and effective in clinical trials and real-life.

Objectives

The present study explores the long-term efficacy and safety of CAN in routine clinical practice conditions in pediatric (age ≥2 years) and adult patients with CAPS (cryopyrin-associated periodic syndromes), FMF (familial Mediterranean fever), TRAPS (tumor necrosis factor receptor-associated periodic syndrome) and HIDS/MKD (hyperimmunoglobulinemia D syndrome/mevalonate kinase deficiency).

Methods

RELIANCE is a prospective, non-interventional, observational study based in Germany. Patients with clinically confirmed diagnoses of AID routinely receiving CAN are enrolled. Besides efficacy parameters regarding disease activity and remission, safety parameters were recorded at baseline and assessed at 6-monthly intervals.

Results

Here, we present the interim analysis of patients with AID (N=199) enrolled in the RELIANCE Registry between October 2017 and December 2021. Mean age in this cohort was 24.4 years (2–79 years) and the proportion of female patients was 53% (N=104). At baseline, median duration of prior CAN treatment was 2 years (0–12 years).

A total of 123 patients (62%) experienced any AE (N=653) among which nasopharyngitis, increase of inflammatory markers and pyrexia were the most frequent AE with incidence rates per 100 patient years (IR) of 8.3, 6.2, and 6.2, respectively.

29 patients (15%) were affected by severe AE (SAE, total number N=90) including 11 patients (6%) with SAE suspected to be drug-related (SADR; total number N=30) with IR from 0.2 to 0.7 (Table 1). Overall, 16 AE comprised upper respiratory tract infections (URI). One death (COVID-19, not related) and one malignancy (skin papilloma, not related) were reported. No vertigo and no hypersensitivity reactions were observed. N=10 (IR 2.36) vaccination reactions were reported (no SAE).

Conclusion

The interim data from the RELIANCE study, the longest running real-life canakinumab registry, confirm safety of long-term canakinumab treatment across the entire study population. A trend for dose-related increase of SAE/SADR requires continuous close monitoring and awareness in patient groups (children, severe phenotypes, certain genotypes) requiring greater than standard dose treatment regimens.

POS1301 OCCURRENCE OF ARTHRITIS IS IN 37% OF THE PATIENTS WITHOUT OVERLYING SKIN INVOLVEMENT IN JUVENILE LOCALIZED SCLERODERMA. SUMMARY OF THE EXTRACUTANEOUS INVOLVEMENT IN A MONOCENTRIC COHORT

Background

Localized scleroderma in childhood (locSSc) occurs with a prevalence of 3.2 to 3.6 per 10 000 children1. There are not many publications assessing in detail the extracutaneous manifestations (EM) of locSSc. It is very important to assess the EM too, because the EM can lead to significant damage and morbidity too.

Objectives

To assess the occurrence of extracutaneous manifestations in locSSc in our cohort and the correlation of the occurring EM to the subtype of locSSc and the localisation of the skin involvement.

Methods

Retrospective chart review of all consecutive patients, who were followed at our centre from January 2000 to July 2020 with the diagnosis of locSSc. The subtype was classified according Laxer et al2. The patients were under the age of 18 years at the time point of the first visit. Demographic and clinical data were extracted.

Results

73 patients could be identified, 71% of them were female. Mean age at disease onset was 8 years (4-14 years). The mean time of follow up was 5 years. The subtype distribution was 42 (57%) linear, 24 (33%) mixed, 6 (8%) circumscribed morphea and 1 (1%) pansclerotic morphea. 9 (21%) of the 42 patients with linear subtype had coup de sabre and 4 (10%) of them had Parry Romberg. Fifty six (76%) patients had EM, 40 (53%) of them had 1 form of EM, 10 (13%) of them 2 forms of EM and 6 (8%) patients 3 forms of EM. 53(73%) of the 76 patients had arthritis. Twenty (37%) of the 53 arthritis involvement occurred on a localisation without overlaying skin involvement. Most frequent localisation of arthritis without overlaying skin involvement was in the hip joints (18%). Of the 53 patients with articular involvement had 31 (58%) linear, 17 (32%) mixed, 4 (7.5) circumscribed morphea and 1 (2%) pansclerotic subtype. 14 (19%) of the 73 had length discrepancy of the extremities and 13 (93%) of them had linear subtype. Neurologic symptoms presenting as headache occurred in 8 (11%) patients, 6 (75%) of them had Parry Romberg subtype and 2 (25%) of them coup de sabre. “White” anterior uveitis was screened according to published recommendations3,4 and it occurred in 3 patients, only one of them had coup the sabre the other two linear and mixed subtype without involvement of the face.

Conclusion

EM is very common and it occurs in 76% of the patients. Thirty seven percent of the articular involvement occurred in joints without overlaying skin involvement, which suggest the importance of the whole body joint count as in juvenile idiopathic arthritis. Only 1 of 3 patients with uveitis had skin involvement in the face, which emphasize the recommended uveitis screening.

OP0218 FREQUENCY OF DEPRESSIVE AND ANXIOUS SYMPTOMS IN PATIENTS WITH JUVENILE IDIOPATHIC ARTHRITIS (JIA) – DATA FROM THE INCEPTION COHORT OF NEWLY DIAGNOSED PATIENTS WITH JIA (ICON)

Background

Psychiatric comorbidities can be a significant additional burden in chronic diseases. The most common chronic inflammatory rheumatic disease in children and adolescents is juvenile idiopathic arthritis (JIA). Data on mental illness in children and adolescents with JIA are heterogeneous.

Objectives

To assess the frequency of depressive and anxious symptoms in patients with JIA compared to healthy peers.

Methods

Data were analysed from JIA patients and healthy controls of the same age included in the inception cohort of newly diagnosed children and adolescents with JIA (ICON). Depressive symptoms (using the Patient Health Questionnaire (PHQ-9, score 0-27) and anxious symptoms (Generalised Anxiety Disorder Scale (GAD-7, score 0-21) were captured 7 or 9 years after inclusion in ICON in patients aged thirteen years or older at the time of filling in these questionnaires. Symptom severity for both instruments was assessed by sum score with the following cut-off values: PHQ-9 score < 5: none, 5-9: mild, 10-14: moderate, 15-19: severe, ≥ 20: very severe. GAD-7 Score < 5: none, 5-9: mild, 10-14: moderate, ≥ 15: severe. Disease parameters such as Physician Global Assessment of Disease Activity (PhGA Disease Activity, numerical rating scale, (NRS),0-10, 0=best), joint count (n) and patient-reported outcomes on functional limitations ((C)HAQ, score 0-3, 0=best), Patient Global Assessment of Well-being (PGA Well-being), pain and fatigue (NRS, 0-10, 0=best) were also documented.

Results

The analysis included 344 patients, 157 (45.6%) < 18 years old (mean 15.5 ± 1.5 years, 64.3% female), 187 (54.4%) ≥ 18 years old (mean 21.5 ± 2.1 years, 65.2% female) and 224 control subjects, 115 (51.3%) < 18 years old (mean 15.2 ± 1.5 years, 60% female), 109 (48.7%) ≥ 18 years old (mean 21.4 ± 1.9 years, 58.7% female). Almost 40% of patients had oligoarthritis (26% persistent OA, 12.5% extended OA), 27% rheumatoid factor (RF)-negative polyarthritis, 6% psoriatic arthritis, 17% enthesitis-related arthritis; 3% each had systemic JIA and RF-positive polyarthritis. In the total cohort, 14% of patients and 7% of controls had a PHQ-9 ≥ 10 and 10% of patients and 2% of controls had a GAD-7 ≥ 10. Within the categories of JIA, the rate of a PHQ-9 ≥ 10 ranged from 9.3% (oligoarthritis extended) to 33.3% (RF-positive polyarthritis) and a GAD-7 ≥ 10 ranged from 0% (systemic arthritis) to 22.2% (psoriatic arthritis).

Patients aged ≥ 18 years had higher scores for both PHQ-9 (≥ 10: 18.7%) and GAD-7 (≥ 10: 14.4%) compared to patients < 18 years (PHQ-9 ≥ 10: 8.3%, GAD-7 ≥ 10: 5.1).

In patients < 18 years with PHQ-9 < 10 versus ≥ 10, there were no significant differences in either PhGA disease activity (0.8±1.6 / 1.0±2.0, p = 0.673) or joint count (0.5±1.3 / 0.5±1.6, p = 0.999). In contrast, there was a significant difference in PhGA disease activity (0.8±1.5 / 1.6±1.4, p = 0.005) but not in joint count (0.7±3.1 / 0.8±1.3, p = 0.850) in patients ≥ 18 years with PHQ-9 < 10 versus PHQ-9 ≥ 10.

Female patients were more often found to have higher scores for depression and anxiety than male patients (PHQ-9 ≥ 10: female 17.5%, male 7.4%, GAD-7 ≥ 10: female 13.5%, male 4.1%) and patients more often had higher scores for depression than controls (PHQ-9 ≥ 10: female patients 17.5%, female controls 8.3%, male patients 7.4%, male controls 4.4%). The difference in the proportion of female patients with GAD-7 ≥ 10 (13.5%) compared to control subjects (2.3%) was remarkable, but in male patients this proportion (4.1%) was only slightly higher than in male control subjects (2.2%).

Conclusion

Depressive and anxious symptoms are common in adolescents and young adults with JIA, especially in females. In the continuous care of these patients, standardised diagnostic tools should be implemented to detect these comorbidities, to optimise therapy and thereby reduce the burden of disease. Further research is needed to identify possible predictors of the development of depression and anxiety in JIA patients in order to pursue preventive approaches.

BIKER WA 29358 is a 5-year multi-centre prospective, observational cohort study including polyarticular JIA patients in Germany starting treatment between 2015 and 2020 with TCZ and matched 1:1 by date of treatment start and region to patients starting an approved TNFi. Clinical disease activity (JADAS10), JADAS MDA (≦3.8)/remission (≦1.0), safety and drug adherence at 12 months were assessed and compared between cohorts.

Results

The analysis included 342 participants with 12-month treatment data (TCZ n=171; TNFi n=171). TCZ was used as 2nd line biologic in the majority of patients (84%) while TNFi were mostly 1st line biologics (86%). Patients starting TCZ had a longer disease duration. Efficacy was demonstrated by a marked decrease in JADAS10 in both cohorts (TCZ vs. TNFi at baseline: 15.0+/-6.7 vs. 14.6+/-6.3; at month 12: 3.8+/-5.1 vs. 3.4+/-4.5). Proportions of patients in TCZ/TNFi cohorts achieving JADAS remission at 12 months were 48%/41% in 1st line biologic users and 32%/33% in 2nd line biologic users. JADAS MDA was achieved in 64%/69% in 1st line and 52%/58% in 2nd line users of TCZ/TNFi.

After 12 months of treatment JADAS10 (mean +/SD) was higher in the 2nd line TNFi cohort compared to the 1st line (4.5+/-5.6 vs. 3.2+/-4.3), similar to patients receiving 2nd or 1st line TCZ (4.0+/-5.2 vs. 2.9+/-4.4). Patients receiving TCZ or TNFi as first biologic reached JADAS10 remission and MDA numerically more frequently but not statistically significant compared to 2nd line users.

Safety was assessed based on adverse event (AE) reporting. 57 (33%) patients in the TCZ cohort and 43 (25%) patients in the TNFi cohort reported AE. The AE rate was significantly higher in the TCZ cohort (69 vs. 44.8/100 patient years, RR 1.5 [95%CI 1.1-2.0], p=0.006, Wald-test). There were 6 serious AE in the TCZ and 3 in the TNFi cohort. Injection site reactions were more common in the TNFi cohort (9 vs. 1, p=0.043). No further differences were identified to date. There was no death and no opportunistic infection.

In the TCZ cohort, 32 patients discontinued treatment, 27 due to lack of efficacy, while in the TNFi cohort only 6 patients discontinued treatment. Treatment discontinuation was more frequent among the 2nd biologic users (n=29; 17.4%) than in first line users (n= 9; 5.1%).

Conclusion

In this first interim analysis, treatment targets were reached with similar frequency after 12 months of treatment with TCZ or TNFi. TCZ was used predominantly as 2nd line biologic. Higher rates of remission /MDA were observed in 1st line compared to 2nd line biologic users. Although more AE were reported in the TCZ cohort, the occurrence of serious AE and infections was comparable in both cohorts. No new safety signals were identified. Observation is ongoing.

POS0171 A STANDARDIZED ASSESSMENT OF TREATMENT AND OUTCOME OF NEWLY DIAGNOSED PATIENTS WITH JIA WITHIN THE PROKIND PROJECT – PATHWAYS FOR POLYARTICULAR JIA

Background

The ProKind Commission of the Society for Paediatric and Adolescent Rheumatology (GKJR) has developed evidence- and consensus-based protocols for the diagnosis and therapy of children and adolescents with defined rheumatic diseases (e.g., [1]). In the ProKind-Rheuma project, it is now investigated whether the protocols are followed in everyday clinical practice and what the treatment-associated outcomes are.

Objectives

To investigate the mode of treatment and treatment response in patients with polyarticular juvenile idiopathic arthritis (pJIA).

Methods

ProKind-Rheuma is a multicenter prospective non-interventional observational study. Patients with pJIA enrolled until 17/1/2022 were included into this analysis. Treatments and outcomes up to the 3-month follow-up visit (3FU) were analyzed. Disease states were categorized based on the 2021 cJADAS10 cutoffs [2].

Results

To date, 18 pediatric rheumatology facilities have participated in ProKind-Rheuma. Data from 203 patients with JIA are available. Of those, 44% have oligoarthritis, 36% polyarthritis, 9% systemic JIA, 6% enthesitis-related arthritis and 3% psoriatic arthritis.

In total, 76 patients were diagnosed with pJIA, 38 with already completed 3FU:

For 23 patients with pJIA and completed 3FU, we were able to analyze the protocol-defined [1] treatment goal of at least “minimal improvement”. In total, 18 (78%) achieved minimal improvement, 5 (22%) missed it. For 4 of those 5 patients, the underlying MTX therapy was escalated to a bDMARD (3 changed to MTX+bDMARD-combi, 1 to bDMARD-mono). In 3 other patients, therapy was also escalated to an MTX+bDMARD-combi.

Between baseline and 3FU, 72% achieved cJADAS10-disease state improvement (Table 1) by at least one category (range 1 - 2), 0% decreased.

Within the first 3 months after diagnosis, the treatment pathways proposed by the ProKind Commission [1] were followed in about three-quarters of patients: i) 5 (13%) received MTX and intra-articular glucocorticoid injections in more than 4 joints (IAGC), but no high-dose intravenous glucocorticoid pulse (HDGC) or bDMARD; ii) 8 (21%) received MTX and HDGC (no bDMARD, no IAGC); iii) 16 (42%) patients received MTX, of whom 4 received a bDMARD up to or at the 3FU (no HDGC, no IAGC). Nine (24%) patients were not treated with MTX or did not fit any of these categories, mostly due to starting bDMARD therapy in conjunction with HDGC or IAGC.

Conclusion

In the routine care of JIA patients with polyarthritis, the proposed treatment protocol and treat-to-target strategy are followed in most patients. At 3FU, improvements of JADAS10 and other outcomes were evident, with 41% having achieved inactive or minimal active disease.

POS0336 COURSE OF UVEITIS IN CHILDREN WITH JUVENILE IDIOPATHIC ARTHRITIS: DATA FROM THE INCEPTION COHORT OF NEWLY DIAGNOSED PATIENTS WITH JIA (ICON-JIA) STUDY

Background

Uveitis is an extra-articular manifestation of Juvenile idiopathic arthritis (JIA) with a prevalence of up to 20% developing most frequently in young girls and patients positive for antinuclear antibodies (ANA). Untreated and uncontrolled uveitis may lead to vision-threatening complications and even blindness.

Objectives

The main objectives of the analyses were to determine the visual prognosis, uveitis complications and necessity of ocular surgery during the first five years of ocular disease. The likelihood of achieving an inflammation-free phase or even a remission without medication were investigated.

Methods

The Inception Cohort of Newly diagnosed patients with JIA (ICON) was initiated in 2010 in order to prospectively follow JIA patients up to 10 years after JIA disease onset. 953 Patients were assessed at enrollment, three-monthly during the first year, and six-monthly afterwards by a standardized physician’s and patient’s case report form including clinical parameters, treatment data and several laboratory parameters such as ESR, CRP or S100A12. Patients who developed uveitis underwent a regular ophthalmological assessment. The treating ophthalmologist three-monthly completed an additional questionnaire, documenting the anterior chamber (AC) cell grade, current uveitis activity (UA) and UA during the previous three months, best corrected visual acuity (BCVA), uveitis-related complications, previous ocular surgery, current topical treatment and clinical course of uveitis and additional parameters. Inactive uveitis was defined by AC cell grade of 0, quiescence of uveitis by inactive uveitis for at least 6 months, and remission by inactive uveitis for at least 6 months without topical steroids or systemic anti-inflammatory medication (steroids or DMARDs).

Results

A total of 133 children developed uveitis in the JIA disease course, of which 97 patients were documented via the ophthalmological questionnaire for at least two years resulting in a mean follow-up of 5.8 years (SD 1.8). 76% were female, 86% ANA positive, 70% oligoarthritis, and 22% rheumatoid factor negative polyarthritis and mean age at JIA onset was 3.1 (SD 2.1) and uveitis onset at 4.4 (SD 2.2) years. The mean duration between JIA onset and uveitis onset was 15.7 (SD 15.6) months. At least one ocular complication was reported for 24% of patients at first uveitis documentation and 47% of patients had at least one ocular complication until the five year follow-up. Among those, posterior synechiae (31%) and cataract (27%) were the most frequent, followed by an increased IOP (12%) with or without glaucomatous changes. Ocular surgery was rarely necessary, and visual acuity remained quite good in the majority of patients: After five years, >90% had BCVA of <0.4 LogMAR (Logarithm of the Minimum Angle of Resolution), and 63.5% even of <0.1 LogMAR. About half of the uveitis patients were already treated with DMARDs at uveitis onset. The rate of treatment with biological DMARDs increased from 10% at first uveitis documentation up to 20% at 5-year follow-up. Three in four patients were treated with topical steroids at first assessment, whereas this proportion decreased to 43%. 80 of 97 patients (83%) achieved uveitis quiescence during the first five years of disease, with more than 50% experiencing more than one episode (mean 1.5 episodes (SD 1.0)) during this time period. The mean duration of uveitis quiescence was 23.2 (SD 15.6) months. A total of 39 (40%) patients achieved uveitis remission during follow-up. The likelihood of remission was associated with a lower JIA disease activity (cJADAS10), lower erythrocyte sedimentation rate (ESR) and a higher age at JIA disease onset.

Conclusion

The rate of ocular complications is already remarkable at uveitis diagnosis, and increases during uveitis disease course despite anti-inflammatory treatment. However, the visual acuity frequently remains unaffected, and the majority of patients achieve uveitis quiescence and even 40% uveitis remission within 5 years of follow-up.

POS1302 PATIENT AND PHYSICIAN REPORTED OUTCOMES OF JUVENILE SYSTEMIC SCLEROSIS PATIENTS SIGNIFICANTLY IMPROVE OVER 12 MONTHS OBSERVATION PERIOD IN THE JUVENILE SYSTEMIC SCLERODERMA INCEPTION COHORT. www.juvenile-scleroderma.com

Background

Juvenile systemic sclerosis (jSSc) is an orphan disease with a prevalence of 3 in 1 000 000 children (1). The Juvenile Systemic Scleroderma Inception cohort (jSScC) is the largest cohort of jSSc patients in the world. The jSScC collects longitudinal data prospectively in jSSc, allowing the evaluation of the development of organ involvement and patients and physician reported outcomes in jSSc over time.

Objectives

To review the changes in the clinical characteristics and patient and physician reported outcomes over 12 months observation period from the time of inclusion into the cohort.

Methods

The jSScC cohort enrolls jSSc patients who developed the first non-Raynaud´s symptom before the age of 16 years and are under the age of 18 years at the time of inclusion (2, 3). We reviewed jSScC patient clinical data and patient and physician reported outcomes, who had 12 months follow up from the time of inclusion until 1st of December 2021.

Results

We could extract data of 113 patients. The female/male ratio was 3.5:1. Median age of onset of Raynaud´s was 10.1 years and the median age of onset of non-Raynaud´s was 10.8 years. Eighty-eight percent of the patients were treated with disease modifying anti-rheumatic drugs (DMARDs) at time of inclusion in the cohort (T0) and 93% after 12 months (T12). Median disease duration was 2.5 years at T0. Antibody profile stayed unchanged. Only 3 clinical parameters changed and improved significantly, the median modified Rodnan skin score improved from 13 to 8 (p=0.002), the number of patients with swollen joints decreased from 17% to 8% (p=0.043) and number of patients with joints with pain on motion decreased from 20% to 12% (p=0.048). All other organ involvement did not show any statistically significant change from T0 to T12.

All collected patient reported outcomes improved significantly from T0 to T12: the patient reported disease activity (VAS 0 – 100) from 40 to 20 (p=0.011), the patient reported disease damage (VAS 0 – 100) from 40 to 20 (p=0.001), patient reported ulceration activity (VAS 0 – 100) from 10 to 0 (p=0.02) and the CHAQ score from 0.3 to 0.1 (p=0.002). Two of the three physician reported outcomes improved significantly, the physician global disease activity (VAS 0 – 100) from 30 to 20 (p=0.011) and physician reported global disease damage (VAS 0 – 100) from 30 to 25 (p=0.028).

Conclusion

Skin and musculoskeletal clinical features improved over 12 months, with almost all patients on DMARDs, supporting likely response of these features to therapy. It was promising that internal organ involvement, like cardiac and lung, although potentially stable, did not significantly worsen or increase. The most striking observation in the positive direction is improvement across several patient and physician reported outcome measures over the 12 month time period in this large international cohort.

Background

Juvenile systemic sclerosis (jSSc) is an orphan disease with a prevalence of 3 in 1 000 000 children (1). In adult patients there are significant differences between the clinical presentation of diffuse and limited subtypes (2). We reviewed clinical differences in presentation of subtypes in patients in the juvenile systemic scleroderma inception cohort up to 2021.

Objectives

To study the clinical presentation of jSSc patients with diffuse (djSSc) and limited (ljSSc) subtypes.

Methods

We reviewed the clinical baseline characteristics of the patients, who were recruited to the juvenile scleroderma inception cohort (jSScC) (3, 4) till 1st of December 2021. jSScC is a prospective cohort of jSSc patients, who developed the first non-Raynaud´s symptom before the age of 16 years and are under the age of 18 years at the time of inclusion.

Results

210 patients with jSSc were included in the cohort, 71% (n=162) had diffuse subtype. The median age at onset of Raynaud phenomenon was 10.4 years (7.3 – 12.9) and the median age at the first non-Raynaud symptom was 10.9 years (7.4 – 13.2). Median disease duration was 2.5 years (1 – 4.4) at the time of inclusion. The female/male ratio was significantly lower in the djSSc subtype (3.7:1 versus 5:1, p<0.001). Antibody profile was quite similar, with the exception of a significantly higher number of anticentromere positive patients in the ljSSc (12% versus 2%, p=0.013). Decreased FVC < 80% was found in approximately 30% and decreased DLCO < 80% was found in around 40% in both subtypes. Pulmonary hypertension assessed by ultrasound was identified in 5% in both groups. Patients with diffuse subtype had significantly higher modified Rodnan Skin Score (mRSS) (16 versus 4.5, p<0.001), sclerodactyly (84% versus 60%, p<0.001), history of digital ulceration (62% versus 31%, p<0.001), decreased Body Mass Index (BMI) < -2 z score (20% versus 4%, p=0.003) and decreased joint range of motion (64% versus 46%, p=0.019). Patients with ljSSc had significantly higher rate of cardiac involvement (13% versus 2%, p=0.001).

Regarding patient related outcomes djSSc patients had more severe disease, looking at patient reported global disease activity (VAS 0 – 100) (40 versus 25, p=0.039), patient reported global disease damage (VAS 0 – 100) (40 versus 25, p=0.021) and patient reported assessment of ulceration activity (10 versus 0, p=0.044). Regarding physician related outcomes the physician reported global disease activity (VAS 0 – 100) (32 versus 20, p<0.001) and physician reported global disease damage (VAS 0 – 100) (30 versus 15, p=0.014) was significantly higher in djSSc.

Conclusion

In this jSSc cohort, the largest in the world, djSSc patients have a significantly more severe disease than ljSSc patients. Interestingly, we found no differences regarding interstitial lung disease and pulmonary hypertension.

POS1299 JUVENILE SYSTEMIC SCLEROSIS TREATMENT PRACTICES IN AN INTERNATIONAL COHORT AND COMPARISON TO RECENT SHARE CONSENSUS GUIDELINES

Background

Juvenile systemic scleroderma (jSSc) is an orphan disease with a prevalence of 3 in 1,000,000 children. Currently no medications are licensed for the treatment of jSSc. Due to its rarity, only recently have the first management and treatment guidelines been published, the jSSc SHARE (Single Hub and Access point for paediatric Rheumatology in Europe) recommendations, reflecting consensus opinion upon pediatric rheumatologists (1).

Objectives

To better understand treatment practices internationally for jSSc, both at baseline and over 24 months observation period and to compare if real world therapies are congruent with the recent SHARE recommendations.

Methods

The juvenile systemic sclerosis inceptions cohort (jSScC) is a multinational cohort that prospectively collects clinical data, including medications at baseline and subsequent visits. The jSScC enrollment criteria include age of onset of the first non-Raynaud symptom younger than 16 years and age younger than 18 years at cohort entrance. The frequency of medications (general category and specific medication) was calculated across the cohort at timepoint 0 (enrollment), 12 months and 24 months.

Results

We extracted data from the jSScC of patients who were followed for 12 or 24 months. 109 patients were followed at time point 0 (T0) and 12 months (T12), and data was available for 77 of them up at 24 months (T24). The mean age of the patients was 13.2 years at the timepoint 0. 77% were female and 75% had diffuse subtype. Disease duration at baseline visit was 3.1 years. The medications the patients were on recorded by the physician were captured at T0, T12 and T24 listed in Table 1.

At baseline half of the patients were on corticosteroids. This is more frequent than typical adult SSc practice but coincides with jSSc SHARE treatment recommendations (#1). After 12 months observation in the cohort over 90% of patients received a DMARD therapy. Methotrexate and mycophenolate mofetil were the most commonly prescribed DMARDs, which also reflects the SHARE treatment recommendations (#2, #3). At 12 months the use of glucocorticoid decreased and the use of bDMARDs increased. In general, biological DMARDs are typically considered in severe or refractory (SHARE recommendation #7), reflecting the lower percentage compared to csDMARDs. Autologous stem cell transplantation was observed in one patient at 12 months, reflecting an option in jSSc with progressive and refractory disease (SHARE recommendation #8). Endothelial receptor antagonists, such as bosentan, were used over time in approximately 20% of the patients, reflecting SHARE recommendation #6 for pulmonary hypertension and/or digital tip ulcers. This is the first evaluation looking at clinical medication practice pattern in jSSc, and its comparison to recently published consensus guidelines.

POS0338 TRANSITION COMPETENCE IN YOUNG PEOPLE WITH JUVENILE IDIOPATHIC ARTHRITIS HAS IMPROVED OVER TIME

Background

In recent years, transition clinics have been set up at an increasing number of paediatric rheumatology sites in Germany to reduce identified deficits in the care of young people with rheumatic diseases1. In addition, the German Rheumatic Diseases League (Deutsche Rheuma-Liga, DRL), the largest self-help organisation in Germany, has been offering support services for young people in transition since 2016, including the interactive website www.mein-rheuma-wird-erwachsen.de.

Objectives

To assess the transition competence of young people with juvenile idiopathic arthritis (JIA) and their knowledge of self-help services.

Methods

Cross-sectional data of the National Paediatric Rheumatology Database (NPRD) from 2016 to 2020 were used to evaluate the health-related transition competence of young people with JIA aged ≥16 years. Health-related knowledge and health-care competence were assessed using a modified self-report instrument2 on a 4-point Likert scale as part of routine documentation in the NPRD. Young people were also asked about their information behaviour and knowledge of new support services. Linear mixed models were used to determine whether health-related transition competence changed between 2016 and 2020, adjusted for disease duration.

Results

During the years 2016 to 2020, between 1.908 to 2.536 patients with JIA aged ≥16 years were annually recorded in the NPRD from 56 to 61 paediatric rheumatology sites. The annual patient collectives comprised 34-39% oligoarthritis, 23-26% RF-negative or RF-positive polyarthritis and 22-27% enthesitis-related arthritis cases. In the years from 2016 to 2020, about one-third of patients had inactive disease (cJADAS-10≤1) and about 60% had no functional limitations (CHAQ=0).

Over the years, the proportions of patients who rated their disease knowledge and health care competence as “very well” increased significantly in most areas. Although over time, no increase in numbers of patients seeking information about their disease outside of rheumatology consultations were recorded (2016: 22.8%; 2020: 20.9%), awareness of the DRL’s new website for young people with rheumatic diseases increased from 7.7% in 2016 to 26.9% in 2020. Compared to those who were unaware of the new website, those who knew about the website were more likely to have received care in rheumatology settings that offer transition clinics and were more likely to be girls (75% vs 65%), to attend high school (51% vs 46%) and to be slightly older (17.6 vs 17.1 years).

Conclusion

The transition competence of young people with JIA seems to have improved over the last five years. During this time, more transition services were made available for young people with rheumatic diseases. However, most young people are not yet aware of these services. Moreover, the effectiveness of the different measures/interventions has yet to be evaluated.

AB1236 CLINICAL CHARACTERISTICS OF JUVENILE ONSET SYSTEMIC SCLEROSIS PATIENTS FROM THE JUVENILE SCLERODERMA INCEPTION COHORT COMPARED TO ADULT AGE JUVENILE-ONSET PATIENTS FROM EUSTAR. ARE THESE DIFFERENCES SUGGESTING RISK FOR MORTALITY?

Background

Juvenile systemic sclerosis (jSSc) is an orphan autoimmune disease with a prevalence of 3 in 1 000 000 children. Information on long-term development of organ involvement and clinical characteristics of jSSc patients in adulthood are lacking. It was believed that patients in adult cohorts may represent a survival biased population.

Objectives

To assess differences in clinical characteristics of jSSc-onset patients from the pediatric age group, with a mean disease duration of 3 years, compared to the adult age jSSc-onset group, with a mean disease duration of 18.5 years.

Methods

We extracted clinical data at time of inclusion into the cohorts from the Juvenile Scleroderma Inception Cohort (jSScC) and data from juvenile-onset adult SSc patients from the European Trials and Research Group (EUSTAR) cohort. We compared the clinical characteristics of the patients by descriptive statistics.

Results

We extracted data of 187 jSSc patients from the jSScC and 236 patients from EUSTAR. The mean age at time of assessment was 13.4 years old in the jSScC and 32.4 years old in EUSTAR. The mean disease duration since first non-Raynaud was 3.0 years in jSScC and 18.5 years in the EUSTAR (Table 1).

We found significant differences between the cohorts. There were more female patients in EUSTAR (87.7% versus 80.2%, p=0.04). More patients had diffuse subtype in jSScC (72.2% versus 40%, p<0.001). The modified Rodnan skin score (mRSS) was significantly higher in jSScC (14.2 versus 12.1, p=0.02). Active digital ulceration occurred more often in EUSTAR (26.6%, versus 17.8% p=0.01), but history of active ulceration was more frequent in jSScC (54.1% versus 43%, p<0.001). Mean DLCO was lower in jSScC (75.4 versus 86.3, p<0.001). Intestinal involvement was significantly more common in jSSc (33.2% versus 23.8%, p=0.04). Esophageal involvement was more common in EUSTAR (63.7% versus 33.7%, p<0.001). (Table 1).

Conclusion

Patients with jSSc-onset who are currently adult age (defined as >18 years of age) are less frequently male and from the diffuse subset, have lower mRSS, less digital ulcers and intestinal involvement. This might represent a combination of both survival bias and/or be explained by the longer observation time with less active disease (i.e. natural progression decreased mRSS over time). Further long-term observational studies with jSSc patients are required to address this issue.

New and Updated Recommendations for the Treatment of Juvenile Idiopathic Arthritis-Associated Uveitis and Idiopathic Chronic Anterior Uveitis

OBJECTIVE

The Multinational Interdisciplinary Working Group for Uveitis in Childhood identified the need to update the current guidelines, and the objective here was to produce this document to guide clinicians managing children with juvenile idiopathic arthritis-associated uveitis (JIAU) and idiopathic chronic anterior uveitis (CAU).

METHODS

The group analyzed the literature published between December 2014 and June 2020 after a systematic literature review conducted by 2 clinicians. Pediatric rheumatologists were paired with ophthalmologists to review the eligible 37 publications. The search criteria were selected to reflect those used for the 2018 Single Hub and Access point for pediatric Rheumatology in Europe (SHARE) recommendations, in order to provide an update, rather than a replacement for that publication. The summary of the current evidence for each SHARE recommendation was presented to the expert committee. These recommendations were then discussed and revised during a video consensus meeting on January 22, 2021, with 14 voting participants, using a nominal group technique to reach consensus.

RESULTS

JIAU treatment was extended to include CAU. Fourteen recommendations regarding treatment of JIAU und CAU with >90% agreement were accepted.

CONCLUSION

An update to the previous 2018 SHARE recommendations for the treatment of children with JIAU with the addition of CAU was created using an evidence-based consensus process. This guideline should help support clinicians to care for children and young people with CAU.

OP0042 LONG-TERM EFFICACY AND SAFETY OF CANAKINUMAB IN PATIENTS WITH FAMILIAL MEDITERRANEAN FEVER (FMF) - INTERIM ANALYSIS OF THE RELIANCE REGISTRY

Background

Familial Mediterranean Fever (FMF) is a chronic disease characterized by recurrent attacks of fever as well as serositis and bears the risk of serious complications (e. g. amyloidosis). Treatment of FMF according to EULAR aims to control acute attacks and subclinical inflammation as well as to improve patient´s quality of life1. Clinical data indicate that the inhibition of interleukin-1β with canakinumab (CAN) is effective in controlling and preventing flares in FMF patients2.

Objectives

The present study explores the long-term efficacy and safety of canakinumab in routine clinical practice conditions in pediatric (age ≥2 years) and adult FMF patients.

Methods

RELIANCE is a prospective, non-interventional, multi-center, observational study based in Germany with a 3-year follow-up period. Patients with clinically confirmed FMF diagnosis who routinely receive canakinumab are enrolled in order to evaluate effectiveness and safety of canakinumab. Disease activity and remission by physicians´ assessment, disease activity, fatigue and impact on social life by patients’ assessment, inflammatory markers and AIDAI (Auto-Inflammatory Diseases Activity Index) score were recorded at baseline and assessed at 6-monthly intervals within the 3-year observation period of the study.

Results

This interim analysis of FMF patients (N=74) enrolled by December 2021 includes baseline as well as 6- to 24-month data. Mean age in this cohort was 25 years (2−61 years) and the proportion of female patients was 51 % (N=38). At baseline, median duration of prior CAN treatment was 1.0 years (0−6 years).

At month 24, physician ratings report around 63% of patients in disease remission and patient-reported disease activity (mean PPA) decreased from moderate (3.0) to low (2.6) during the observation period. Other disease activity parameters also decreased (Table 1). A total of 18 serious adverse events were reported, of which 2 (1 case of tonsillectomy and 1 case of tachycardia) were classified as drug - related.

OA37 Secukinumab treatment in children and adolescents with enthesitis-related arthritis and juvenile psoriatic arthritis: efficacy and safety results from a Phase 3 study

Background/Aims

Enthesitis-related arthritis (ERA) and juvenile psoriatic arthritis (JPsA) are two conditions that represent paediatric correlates of axial spondyloarthritis (axSpA) and adult psoriatic arthritis (PsA), respectively. Secukinumab has demonstrated efficacy and safety in adult patients with PsA, ankylosing spondylitis, and non-radiographic axSpA. This study evaluated efficacy and safety of secukinumab using a randomized, double-blind, placebo-controlled flare prevention design in patients with active ERA and JPsA.

Methods

Patients (aged 2 to &lt; 18 years) classified as ERA or JPsA according to ILAR criteria of ≥ 6 months’ duration with active disease were included. The 2-year study consisted open-label subcutaneous secukinumab (75/150 mg in patients &lt;50/ ≥50 kg) treatment at baseline, and at Weeks 1, 2, 3, 4, 8, and 12 in treatment period (TP) 1. Responders who achieved at least JIA ACR 30 response at Week 12 were randomized into the double-blind TP2 to continue secukinumab or placebo every 4 weeks until disease flare, or up to Week 100. Primary endpoint was time to flare in TP2; key secondary endpoints included JIA ACR 30/50/70/90/100, inactive disease, juvenile arthritis disease activity score (JADAS), enthesitis and active joint counts, and safety. Analysis of time to flare in TP2 included proportion of patients with disease flare, Kaplan-Meier estimate of median days for time to flare, hazard ratio (HR) estimate, and stratified log-rank test P-value. Intent-to-treat (ITT) analysis using non-responder imputation (NRI) and as-observed analysis were performed for JIA ACR 30/50/70/90/100 responses and inactive disease.

Results

86/97 (88.7%) screened patients were enrolled in TP1 (mean age, 13.1 years; female, 33.7%; ERA, n = 52; JPsA, n = 34) with a mean JADAS-27 score of 15.1 and enthesitis count of 2.6 at baseline. At Week 12, 75/83 (90.4%) patients achieved JIA ACR 30 and entered TP2. There were 21 flares in placebo-treated and 10 flares in secukinumab-treated patients during TP2. Primary endpoint was met: secukinumab-treated patients had significantly longer time to flare versus placebo, resulting in a 72% reduced flare risk (HR: 0.28; 95% CI: 0.13-0.63; P&lt;0.001). There were minor differences between the ITT and as-observed analysis in JIA ACR responses and inactive disease in TP1. Improvement in JADAS-27 score was observed in patients in both ERA and JPsA categories (mean JADAS-27 score of 4.6). Rates of adverse events (AEs; 91.7% vs 92.1%) and serious AEs (14.6% vs 10.5%) in secukinumab and placebo groups were comparable in entire TP. No new safety signals were observed in patients receiving secukinumab (injection-site reaction, n = 1; overall patient-years=141.5).

Conclusion

In children and adolescents with ERA and JPsA, efficacy of secukinumab was demonstrated with significantly longer time to flare versus placebo, with sustained improvement of signs and symptoms up to Week 104. Efficacy was observed in ERA and JPsA patients along with a favorable safety profile.

Drivers of non-zero physician global scores during periods of inactive disease in juvenile idiopathic arthritis

Objective

To investigate the frequency in which the physician provides a global assessment of disease activity (PhGA) >0 and an active joint count (AJC)=0 in children with juvenile idiopathic arthritis (JIA) and search for determinants of divergence between the two measures.

Methods

Data were extracted from a multinational cross-sectional dataset of 9966 patients who had JIA by International League of Associations for Rheumatology criteria, were recruited between 2011 and 2016, and had both PhGA and AJC recorded by the caring paediatric rheumatologist at the study visit. Determinants of discordance between PhGA>0 and AJC=0 were searched for by multivariable logistic regression and dominance analyses.

Results

The PhGA was scored >0 in 1647 (32.3%) of 5103 patients who had an AJC of 0. Independent associations with discordant assessment were identified for tender or restricted joint count >0, history of enthesitis, presence of active uveitis or systemic features, enthesitis-related or systemic arthritis, increased acute phase reactants, pain visual analogue scale (VAS)>0, and impaired physical or psychosocial well-being. In dominance analysis, tender joint count accounted for 35.43% of PhGA variance, followed by pain VAS>0 (17.72%), restricted joint count >0 (16.14%) and physical health score >0 (11.42%).

Conclusion

We found that many paediatric rheumatologists did not mark a score of 0 for patients who they found not to have active joints. The presence of pain in joints not meeting the definition of active joint used in JIA was the main determinant of this phenomenon.

Secukinumab in the treatment for patients with juvenile enthesitis related arthritis non-responsive to anti-TNF treatment according the Juvenile Spondyloarthritis Disease Activity Index

OBJECTIVES

To review the effectiveness of secukinumab (SEC) in patients with juvenile idiopathic enthesitis related arthritis (ERA), who had partial or no response on anti-TNF therapy.

METHODS

We conducted a retrospective monocentric chart review of patients with ERA, who were treated with SEC, until March 15th 2019. We used the JADAS10 and the Juvenile Spondyloarthritis Disease Activity Index (jspADA) to evaluate response. We analysed the onset of AE and SAE.

RESULTS

We analysed 17 patients with ERA. The mean age at the start of the treatment was 19.5 years (SD 4.9, range 13-34 years, median 18.2). The mean disease duration was 6.3 years (SD 3.3, range 2-12 years). The patients received in average 1.9 (SD1.0) different anti-TNF'́s before switching to SEC. SEC was applied at the start of the treatment with 150 mg per dose (n=13, 76.5%) and 300 mg per dose (n=4, 23.5%). The dose of 150 mg was increased in 11 patients (85% of 13) after baseline. The mean follow-up of patients was 18.2 months (SD 7.2) accounting to 25.8 years under exposure to SEC. The jspADA (mean change of -1.3; p<0.001; 95%CI: -1.9 to -0.7) and JADAS10 (mean change of -2.4; p=0.021; 95%CI: -4.5 to -0.4) signi cantly improved between baseline and the 24-month follow-up. There was no serious adverse event observed.

CONCLUSIONS

In our anti-TNF non-responder patients SEC showed good effectiveness. The 150 mg dose seems to be insufficient in anti-TNF non-responder patients and most patients had to be escalated to the 300 mg/dose.

Outcome of adult patients with JIA treated with the biosimilar Benepali®: results of the biologic register JuMBO

BACKGROUND

To analyze therapy adherence, safety, and outcome in adult patients with juvenile idiopathic arthritis (JIA) treated with the etanercept biosimilar Benepali^® (Biogen Inc, Cambridge, USA).

METHODS

Data from the prospective registry, JuMBO (Juvenile arthritis MTX/Biologics long-term Observation), were used for the analysis. JuMBO is a long-term observational cohort study. It follows adult patients with JIA who were formerly included in the national JIA biologic register (BiKeR Registry). Both registries provide individual trajectories of clinical data and outcomes from childhood to adulthood in JIA patients treated with disease-modifying anti-rheumatic drugs (DMARDs).

RESULTS

Eighty-three patients from the German JuMBO registry were treated with Benepali^®. Of these, 74% had switched from Enbrel^® (Pfizer Inc., NYC, USA) the originator of etanercept to Benepali^® for cost reasons. Therapy survival of patients treated with Benepali^® in comparison to Enbrel^® in patients matched by significant parameters was comparable. Adverse events (AE) were reported in 25.3% and serious adverse events (SAE) in 9.6% of patients. Physicians rated no SAE causative related to Benepali^®. The majority of SAEs were surgical/medical procedures and there was only one infection. All efficacy parameters (cJADAS-10, Physician Global Assessment, number of joints with active arthritis, patients' overall well-being, pain, and HAQ) demonstrated improvement over 24 months (p-values were not significant). 9.6% of patients permanently discontinued Benepali® because of an AE.

CONCLUSIONS

Tolerability and effectiveness of the biosimilar Benepali^® were satisfactory and therapy survival was comparable to the originator. Further data on therapy with biologics and biosimilars such as Benepali^® must be collected by registries such as BiKeR and JuMBO in order to optimize therapy and patient outcomes and to reduce costs in the health system in the long term.

Does Juvenile Idiopathic Arthritis Affect the Course of Legg-Calvé-Perthes Disease? A Case-Control Study with a Mean Follow-Up of 8 Years

BACKGROUND

This study aimed to determine the clinical and radiological course in children who had Legg-Calvé-Perthes disease (LCPD) associated with juvenile idiopathic arthritis (JIA).

METHODS

In a retrospective chart review between 2007 and 2019, eight consecutive JIA patients diagnosed with concomitant LCPD were identified and compared with a case-control group of 10 children with LCPD only.

RESULTS

LCPD was diagnosed at a mean age of 8.1 years (3.0-14.7) in children with JIA as compared to 6.1 years (2.9-10.0) in controls. According to the modified Harris Hip Score (mHHS), four children with JIA and all controls had an excellent result. Regarding the fragmentation severity and the duration of each stage, we found no differences using the lateral pillar and modified Elizabethtown classification. Five hips were classified as Stulberg I/II, two hips as Stulberg III, and one hip as Stulberg V with no evidence of hip dysplasia or severe overcoverage in either group.

CONCLUSIONS

The radiological outcome of LCPD did not differ between both groups, while the clinical outcome was slightly better in controls. Physicians should be aware that children with LCPD may have JIA too. In suspicious cases, further investigations are recommended, and patients should be referred to pediatric rheumatologists.

Prior elicitation of the efficacy and tolerability of Methotrexate and Mycophenolate Mofetil in Juvenile Localised Scleroderma

Background

Evidence is lacking for safe and effective treatments for juvenile localised scleroderma (JLS). Methotrexate (MTX) is commonly used first line and mycophenolate mofetil (MMF) second line, despite a limited evidence base. A head to head trial of these two medications would provide data on relative efficacy and tolerability. However, a frequentist approach is difficult to deliver in JLS, because of the numbers needed to sufficiently power a trial. A Bayesian approach could be considered.

Methods

An international consensus meeting was convened including an elicitation exercise where opinion was sought on the relative efficacy and tolerability of MTX compared to MMF to produce prior distributions for a future Bayesian trial. Secondary aims were to achieve consensus agreement on critical aspects of a future trial.

Results

An international group of 12 clinical experts participated. Opinion suggested superior efficacy and tolerability of MMF compared to MTX; where most likely value of efficacy of MMF was 0.70 (95% confidence interval (CI) 0.34-0.90) and of MTX was 0.68 (95% CI 0.41-0.8). The most likely value of tolerability of MMF was 0.77 (95% CI 0.3-0.94) and of MTX was 0.62 (95% CI 0.32-0.84). The wider CI for MMF highlights that experts were less sure about relative efficacy and tolerability of MMF compared to MTX. Despite using a Bayesian approach, power calculations still produced a total sample size of 240 participants, reflecting the uncertainty amongst experts about the performance of MMF.

Conclusions

Key factors have been defined regarding the design of a future Bayesian approach clinical trial including elicitation of prior opinion of the efficacy and tolerability of MTX and MMF in JLS. Combining further efficacy data on MTX and MMF with prior opinion could potentially reduce the pre-trial uncertainty so that, when combined with smaller trial sample sizes a compelling evidence base is available.
