RESUMO
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. TRIAL REGISTRATION: Clinicaltrials.gov, NCT01357668.
RESUMO
OBJECTIVE: To investigate the safety and efficacy of subcutaneous tocilizumab (SC-TCZ) treatment in a long-term extension (LTE) of clinical trials in polyarticular or systemic juvenile idiopathic arthritis (pJIA or sJIA). METHODS: Patients with pJIA or sJIA from two open-label, 52-week phase 1b core trials of SC-TCZ who had adequate response per investigator assessment entered the LTE and continued SC-TCZ treatment according to body weight-based dosing regimens until commercial availability or up to 5 years. Pharmacokinetics, pharmacodynamics, and efficacy were assessed for up to 3 years, and safety for up to 5 years in the LTE. RESULTS: Forty-four patients with pJIA and 38 patients with sJIA entered the LTE. Tocilizumab trough concentrations were maintained within the range expected to provide clinical benefit (mean values: pJIA, â¼10 µg/ml; sJIA, â¼75 µg/ml over 3 years). Pharmacodynamic parameters (interleukin-6, soluble interleukin-6 receptor, erythrocyte sedimentation rate, C-reactive protein) were maintained throughout the LTE at levels achieved in the core trials. Inactive disease per American College of Rheumatology provisional criteria was reported for 90% (17/19) and 53% (8/15) of patients with pJIA and 91% (10/11) and 92% (12/13) of patients with sJIA in the <30 and ≥30 kg body weight groups, respectively. Serious adverse events in the LTE were reported in six patients with pJIA (13.6%; five serious infections) and five patients with sJIA (13.2%; one serious infection). CONCLUSION: Patients with pJIA or sJIA experienced long-term disease control with SC-TCZ treatment. Long-term safety was consistent with the known tocilizumab safety profile. CLINICAL TRIAL REGISTRATION: clinicaltrials.gov, NCT02165345.

OBJECTIVE: Behçet's syndrome (BS) is a rare disorder with a relapsing-remitting course. Clinical variance across geographical regions and different age groups has been observed. This study matched the demographic, clinical and treatment features of adult- and juvenile-onset BS in the Italian population. METHODS: Two clinical databases of BS patients were compared. The paediatric BS database was collected at the Meyer Children's Hospital, Florence, while the adult BS database was collected at the Careggi University Hospital, Florence. RESULTS: A familiar predisposition for BS was significantly more frequent in the paediatric cohort (3/33 vs 1/165, P = 0.015). No difference emerged in terms of prevalence of HLA-B51 positivity. The proportion of patients meeting the revised ICBD and/or the ISG criteria at BS diagnosis was comparable in the two cohorts. No significant difference emerged between the two cohorts in terms of muco-cutaneous, ocular and neurological involvement, and gastrointestinal symptoms. Articular manifestations resulted as more common in the paediatric cohort, whereas venous vascular events were more frequent in the adult cohort. Regarding treatment strategy, paediatric patients more frequently received no treatment or corticosteroid monotherapy. Conversely, the use of DMARDs, both traditional and biologic, was significantly higher in the adult cohort. CONCLUSION: Remarkable differences between juvenile-onset and adult-onset BS, both in terms of gender, familiar predisposition and clinical manifestations have been observed and a different therapeutic approach in the real clinical practice of the two settings emerged. Prospective, comparison studies with a longer follow-up are encouraged to provide further data about the disease course for juvenile- and adult-onset BS.

OBJECTIVES: Genome-wide association studies (GWAS) have identified loci associated with estimated glomerular filtration rate (eGFR). Few LN risk loci have been identified to date. We tested the association of SLE and eGFR polygenic risk scores (PRS) with repeated eGFR measures from children and adults with SLE. METHODS: Patients from two tertiary care lupus clinics that met ≥4 ACR and/or SLICC criteria for SLE were genotyped on the Illumina MEGA or Omni1-Quad arrays. PRSs were calculated for SLE and eGFR, using published weighted GWA-significant alleles. eGFR was calculated using the CKD-EPI and Schwartz equations. We tested the effect of eGFR- and SLE-PRSs on eGFR mean and variance, adjusting for age at diagnosis, sex, ancestry, follow-up time, and clinical event flags. RESULTS: We included 1158 SLE patients (37% biopsy-confirmed LN) with 36 733 eGFR measures over a median of 7.6 years (IQR: 3.9-15.3). LN was associated with lower within-person mean eGFR [LN: 93.8 (s.d. 26.4) vs non-LN: 101.6 (s.d. 17.7) mL/min per 1.73 m2; P < 0.0001] and higher variance [LN median: 157.0 (IQR: 89.5, 268.9) vs non-LN median: 84.9 (IQR: 46.9, 138.2) (mL/min per 1.73 m2)2; P < 0.0001]. Increasing SLE-PRSs were associated with lower mean eGFR and greater variance, while increasing eGFR-PRS was associated with increased eGFR mean and variance. CONCLUSION: We observed significant associations between SLE and eGFR PRSs and repeated eGFR measurements, in a large cohort of children and adults with SLE. Longitudinal eGFR may serve as a powerful alternative outcome to LN categories for discovery of LN risk loci.

OBJECTIVES: Juvenile psoriatic arthritis (JPsA) has varied clinical features that are distinctive to other juvenile idiopathic arthritis (JIA) categories. This study investigates whether such features impact patient-reported and clinical outcomes. METHODS: Children and young people (CYP) were selected if recruited to the Childhood Arthritis Prospective Study, a UK multicentre JIA inception cohort, between January 2001 and March 2018. At diagnosis, patient/parent-reported outcomes (as age-appropriate) included the parental global assessment (10 cm VAS), functional ability (CHAQ), pain (10 cm VAS), health-related quality of life (CHQ psychosocial score), mood/depressive symptoms (MFQ) and parent psychosocial health (GHQ). Three-year outcome trajectories have previously been defined using active joint counts, physician and parent global assessments (PGA, PaGA respectively). Patient-reported outcomes and outcome trajectories were compared in i) CYP with JPsA versus other JIA categories, ii) CYP within JPsA, with and without psoriasis via multivariable linear regression. RESULTS: There were no significant differences in patient-reported outcomes at diagnosis between CYP with JPsA and non-JPsA. Within JPsA, those with psoriasis had more depressive symptoms (coefficient = 9.8, 95% CI = 0.5-19.0) than those without psoriasis at diagnosis. CYP with JPsA had 2.3 times the odds of persistent high PaGA than other ILAR categories, despite improving joint counts and PGA (95% CI 1.2, 4.6). CONCLUSION: CYP with psoriasis at JPsA diagnosis report worse mood, supporting a greater disease impact in those with both skin and joint involvement. Multidisciplinary care with added focus to support wellbeing in children with JPsA plus psoriasis may help improve these outcomes.
RESUMO
OBJECTIVES: Adolescents with juvenile-onset autoimmune inflammatory rheumatic diseases (AIIRDs) could be at risk for disease flare secondary to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection or to withholding anti-inflammatory therapy. While vaccination can protect against coronavirus disease 2019 (COVID-19), safety and immunogenicity data regarding anti-SARS-CoV-2 vaccines among adolescents with AIIRDs are limited. This international, prospective, multicentre study evaluated the safety and immunogenicity of the BNT162b2 anti-SARS-CoV-2 vaccine among adolescents and young adults with juvenile-onset AIIRDs, 80% of whom are on chronic immunomodulatory therapy. METHODS: Vaccine side effects, disease activity and short-term efficacy were evaluated after 3 months in 91 patients. Anti-spike S1/S2 IgG antibody levels were evaluated in 37 patients and 22 controls 2-9 weeks after the second dose. RESULTS: A total of 91 patients and 40 healthy controls were included. The safety profile was good, with 96.7% (n = 88) of patients reporting mild or no side effects and no change in disease activity. However, three patients had transient acute symptoms: two following the first vaccination (renal failure and pulmonary haemorrhage) and one following the second dose (mild lupus flare vs viral infection). The seropositivity rate was 97.3% in the AIIRD group compared with 100% among controls. However, anti-S1/S2 antibody titres were significantly lower in the AIIRD group compared with controls [242 (s.d. 136.4) vs 387.8 (57.3) BAU/ml, respectively; P < 0.0001]. No cases of COVID-19 were documented during the 3 month follow-up. CONCLUSION: Vaccination of juvenile-onset AIIRD patients demonstrated good short-term safety and efficacy and a high seropositivity rate but lower anti-S1/S2 antibody titres compared with healthy controls. These results should encourage vaccination of adolescents with juvenile-onset AIIRDs, even while on immunomodulation.

OBJECTIVE: Previous reports have suggested that juvenile-onset SLE is associated with a worse prognosis than adult-onset disease. There have been limited studies in adolescents. We sought to assess the effect of adolescent-onset SLE on the clinical course of a large multi-ethnic cohort. METHODS: Patients consisted of individuals diagnosed with SLE between 11 and 18 years of age in a tertiary referral centre. All patients with adult-onset disease were used as controls. Data were analysed by univariable and multivariable analysis for demographic, clinical and serological data. RESULTS: One hundred and twenty-four patients with adolescent-onset and 484 patients with adult-onset disease were identified. There was a higher percentage of males (12.9% vs 7.2%; P = 0.036) and patients of Asian ethnicity within the adolescent group (P < 0.01). By univariable analysis, adolescent-onset SLE was associated with more frequent LN and haemolytic anaemia and less serositis and SS. Ischaemic vascular events occurred in 32 adult-onset patients (6.6%) and 3 adolescent-onset patients (2.4%; P = 0.08). Thirty-five adult-onset patients developed cancer (6.8%) compared with five of the adolescent-onset group (4.8%; P = 0.54). The standardized mortality rate was significantly increased in females with adolescent-onset SLE (14.4; 95% CI 4.44, 24.4) compared with patients with adult-onset SLE. By multivariable analysis, adolescent-onset SLE retained a significant association with LN. CONCLUSION: Adolescent-onset SLE is associated with a significantly increased risk of LN and, importantly, with a marked increase in mortality. These data suggest a more aggressive phenotype of disease in patients with onset of SLE in adolescence and supports the need for intensive follow-up and intensive therapy in this population.

OBJECTIVE: The aim of this study was to examine the influence of chemokines and lipids on cardiac function in patients with active and inactive JDM and matched controls. METHODS: Fifty-four JDM patients were clinically examined a median 16.8 years (range 2-38) after disease onset and compared with 54 sex- and age-matched controls. Inactive disease was defined by the PRINTO criteria. Serum levels of chemokines were analysed by Luminex technology. Echocardiography was performed and analysed blinded to patient information. Long-axis strain and e' were used as parameters of systolic and diastolic function, respectively. RESULTS: In patients, but not in controls, eotaxin and monocyte chemoattractant protein 1 (MCP-1) correlated with systolic (r = -0.65 and r = -0.45) and diastolic (r = -0.59 and r = -0.65) function, particularly in those with active disease (systolic function, r = -0.74 and r = -0.60; diastolic function, r = -0.69 and r = -0.80). Total cholesterol level was lower in patients than controls [mean 4.19 mmol/l (s.d. 0.82) vs 4.60 (0.87), P ≤ 0.01]. However, total cholesterol levels in the upper normal range were associated with systolic (r = -0.56, P < 0.01) and diastolic (r = -0.64, P < 0.001) dysfunction and with high eotaxin and MCP-1 (r = 0.56 and r = 0.50, P < 0.01) in patients with active disease, but not in those with inactive disease or in controls (all r < ±0.2). CONCLUSION: In the active disease state of JDM, eotaxin and MCP-1 were associated with cardiac dysfunction, possibly through sustained inflammation. In those with active disease and cholesterol levels in the upper normal range, eotaxin and MCP-1 might enhance susceptibility to cardiac dysfunction.

There has been a concerted and important international effort to develop and validate disease activity and outcome instruments specific to JIA in recent years. This review aims to describe the disease assessment indices important to routine clinical care and integral to the design of outcome studies and clinical trials in JIA. In view of the increasing number of JIA clinical studies and clinical trials, together with a number of national and international paediatric biologic registers, it is important that knowledge of these new outcome measures is widespread, such that results can be placed in a meaningful context.
