Objective
To assess the efficacy and safety of rilonacept, an interleukin‐1 inhibitor, in a randomized, double‐blind, placebo‐controlled trial.
Methods
An initial 4‐week double‐blind placebo phase ...was incorporated into a 24‐week randomized multicenter design, followed by an open‐label phase. Seventy‐one children who had active arthritis in ≥2 joints were randomized (1:1) to the 2 arms of the study. Patients in the rilonacept arm received rilonacept (loading dose 4.4 mg/kg followed by 2.2 mg/kg weekly, subcutaneously) beginning on day 0. Patients in the placebo arm received placebo for 4 weeks followed by a loading dose of rilonacept at week 4 followed by weekly maintenance doses. The primary end point was time to response, using the adapted American College of Rheumatology Pediatric 30 criteria coupled with the absence of fever and taper of the dosage of systemic corticosteroids, using prespecified criteria.
Results
The time to response was shorter in the rilonacept arm than in the placebo arm (χ2 = 7.235, P = 0.007). The secondary analysis, which used the same response criteria, showed that 20 (57%) of 35 patients in the rilonacept arm had a response at week 4 compared with 9 (27%) of 33 patients in the placebo arm (P = 0.016). Exacerbation of systemic juvenile idiopathic arthritis (JIA) was the most common severe adverse event. More patients in the rilonacept arm had elevated liver transaminase levels (including levels more than 3 times the upper limit of normal) compared with those in the placebo arm. Adverse events were similar in the 2 arms of the study.
Conclusion
Rilonacept was generally well tolerated and demonstrated efficacy in active systemic JIA.
Aim
To assess safety of COVID‐19 vaccination in paediatric patients with immune‐mediated inflammatory disease (IMID).
Methods
Subjects of 5–21 years of age with IMID who received at least one ...COVID‐19 vaccine completed electronic surveys after each vaccine to assess side effects within 1 week of vaccination, current medications and COVID‐19 testing after vaccination. Charts were reviewed for COVID‐19 polymerase chain reaction and IgG response to SARS‐CoV‐2 spike protein results and for disease flare during the study period.
Results
Among 190 enrolled subjects, 71% were female, with median age 17 (range 6–21) years. The most common diagnosis was juvenile idiopathic arthritis/rheumatoid arthritis (55%). 78% of subjects were taking immunosuppressive medication. At least one side effect was reported in 65% of subjects after any dose of the vaccine; with side effects in 38%, 53% and 55% of subjects after the first, second and third vaccine doses, respectively. The most common side effects were injection site pain (59%), fatigue (54%) and headache (39%). No anaphylaxis or myocarditis was reported. Three subjects (2%) experienced disease flare.
Conclusion
In our cohort of paediatric patients with IMID, observed side effects were found to be mild and disease flare rates were found to be low following COVID‐19 vaccination.
Abstract
Objectives
To assess the heterogeneity in factors affecting physician’s global assessment of disease activity (PhGA) and in PhGA scoring of multiple JIA patient’s case scenarios.
Methods
An ...electronic web-based questionnaire of factors potentially considered in PhGA was sent worldwide to members of PRINTO and the Pediatric Rheumatology Care and Outcomes Improvement Network (PR-COIN). The respondents were asked to rate from 0 to 100 the relevance of 17 factors possibly affecting PhGA scoring and to derive a PhGA score of 17 detailed JIA patient cases. The median and interquartile range was used to measure the heterogeneity in the scoring. To demonstrate the consistency among the PhGA scores of the patient cases provided by multiple physicians, we assessed the inter-rater reliability using intra-class correlation.
Results
The questionnaire was completed by 491 respondents. A large individual variation was observed in the impact of different factors on PhGA when assessing JIA. For non-systemic JIA the presence of fever had the largest variation and swollen joint count had the smallest. For sJIA, the largest variation was seen in the presence of erosions and the smallest in the presence of fever. The intra-class correlation of the group for PhGA scoring of patient cases was 0.53 (95% CI 0.38, 0.72).
Conclusions
In a sample of worldwide respondents, the scoring of the PhGA is divergent. Consensus on PhGA scoring guidelines is required to obtain a consistent assessment of patients.
Abstract
Objectives
Immunosuppressed paediatric patients with rheumatic disease (RD) may be at risk for severe or critical disease related to severe acute respiratory syndrome coronavirus 2 ...(SARS-CoV-2) infection. Data remain scarce on coronavirus disease 2019 (COVID-19) outcomes in paediatric RD patients. The aim of this study was to determine the seroprevalence of SARS-CoV-2 IgG and to describe COVID-19 outcomes in immunosuppressed paediatric RD patients.
Methods
Patients diagnosed with RD before age 18 years and treated with at least one immunosuppressive medication for at least 3 months were enrolled from a tertiary paediatric rheumatology practice in New York and also underwent routine SARS-CoV-2 IgG testing from May to November 2020. A total of 571 patients were screened and 262 were enrolled. SARS-CoV-2 IgG-positive subjects were assessed for symptoms of COVID-19 infection. SARS-CoV-2 PCR results were recorded where available. Demographic, diagnostic, medication and outcome data were collected.
Results
Of 262 subjects (186 female), 35 (13%) were SARS-CoV-2 IgG positive; 17 (49%) had symptoms suggestive of COVID-19. Of the 17 patients who had SARS-CoV-2 PCR testing, 11 (65%) were PCR positive, 7 of whom were IgG positive. Most SARS-CoV-2 IgG-positive subjects were not PCR tested. The most common symptoms in IgG- and/or PCR-positive subjects were fever, fatigue and cough. No SARS-CoV-2 IgG- or PCR-positive subject developed severe or critical COVID-19 or required hospitalization.
Conclusions
This is the first report of clinical outcomes of SARS-CoV-2 infection and seroprevalence of SARS-CoV-2 IgG in a large cohort of paediatric RD patients. Most SARS-CoV-2 IgG-positive subjects had no symptoms of COVID-19 infection. Symptomatic subjects all had mild COVID-19 symptoms, suggesting that the risk of severe or critical COVID-19 in immunosuppressed paediatric RD patients is minimal.
The OMERACT Juvenile Idiopathic Arthritis (JIA) Working Group (WG) aimed to reach agreement on a consensus-based definition and description of the core domain related to patient perception of overall ...well-being and disease activity.
A committee of patient research partners, clinicians, methodologists, and researchers drafted working definitions and descriptions. The WG conducted two iterative electronic stakeholder surveys to obtain consensus on domain description, definition, and the distinction between patient perception of overall well-being and disease activity. These definitions were then presented at the OMERACT 2023 Special Interest Group (SIG) session for agreement.
Forty-five participants, from 7 countries and 4 continents, were comprised of six patients, 18 caregivers, and 21 healthcare providers. The consensus threshold (70%) was exceeded on all survey questions from both stakeholder groups (patients/caregivers, all others). Agreement was obtained on the new definition, description, and domain title, along with agreement on separate assessments of two target domains, patient perception of overall well-being as it relates to disease and patient perception of disease activity.
Through an iterative consensus process and achieving agreement from the OMERACT SIG session attendees, the JIA WG has created a detailed definition and description for the two target domains in the patient perception of overall well-being related to disease core domain of the JIA mandatory core domain set. The next phase of this work will be instrument selection using the OMERACT filter 2.2.
Objective
To describe the selection, development, and implementation of quality measures (QMs) for juvenile idiopathic arthritis (JIA) by the Pediatric Rheumatology Care and Outcomes Improvement ...Network (PR‐COIN), a multihospital learning health network using quality improvement methods and leveraging QMs to drive improved outcomes across a JIA population since 2011.
Methods
An American College of Rheumatology–endorsed multistakeholder process previously selected initial process QMs. Clinicians in PR‐COIN and parents of children with JIA collaboratively selected outcome QMs. A committee of rheumatologists and data analysts developed operational definitions. QMs were programmed and validated using patient data. Measures are populated by registry data, and performance is displayed on automated statistical process control charts. PR‐COIN centers use rapid‐cycle quality improvement approaches to improve performance metrics. The QMs are revised for usefulness, to reflect best practices, and to support network initiatives.
Results
The initial QM set included 13 process measures concerning standardized measurement of disease activity, collection of patient‐reported outcome assessments, and clinical performance measures. Initial outcome measures were clinical inactive disease, low pain score, and optimal physical functioning. The revised QM set has 20 measures and includes additional measures of disease activity, data quality, and a balancing measure.
Conclusion
PR‐COIN has developed and tested JIA QMs to assess clinical performance and patient outcomes. The implementation of robust QMs is important to improve quality of care. PR‐COIN's set of JIA QMs is the first comprehensive set of QMs used at the point‐of‐care for a large cohort of JIA patients in a variety of pediatric rheumatology practice settings.
Nonadherence is currently an underrecognized and potentially modifiable obstacle to care in juvenile idiopathic arthritis (JIA). The purpose of our study was to design and implement a standardized ...approach to identifying adherence barriers for youth with JIA across 7 pediatric rheumatology clinics through the Pediatric Rheumatology Care and Outcomes Improvement Network (PR-COIN) and to assess the frequency of adherence barriers in patients and their caregivers across treatment modalities.
An iterative process using coproduction among parents and providers of patients with JIA was used to design the Barriers Assessment Tool to screen for adherence barriers across 4 treatment modalities (i.e., oral medications, injectable medications, infusions, and physical/occupational therapy). This tool was implemented in 7 rheumatology clinics across the United States and patient responses were collected for analysis.
Data were collected from 578 parents and 99 patients (n = 44 parent-child dyads). Seventy-seven percent (n = 444) of caregivers and 70% (n = 69) of patients reported at least 1 adherence barrier across all treatment components. The most commonly reported adherence barriers included worry about future consequences of therapy, pain, forgetting, side effects, and embarrassment related to the therapy. There was no significant difference between endorsement of barriers between parents and adolescents.
Implementing a standardized tool assessing adherence barriers in the JIA population across multiple clinical settings is feasible. Systematic screening sheds light on the factors that make adherence difficult in JIA and identifies targets for future adherence interventions in clinical practice.
Objective
To determine the relationship between serum levels of S100A8/A9 and S100A12 and the maintenance of clinically inactive disease during anti–tumor necrosis factor (anti‐TNF) therapy and the ...occurrence of disease flare following withdrawal of anti‐TNF therapy in patients with polyarticular forms of juvenile idiopathic arthritis (JIA).
Methods
In this prospective, multicenter study, 137 patients with polyarticular‐course JIA whose disease was clinically inactive while receiving anti‐TNF therapy were enrolled. Patients were observed for an initial 6‐month phase during which anti‐TNF treatment was continued. For those patients who maintained clinically inactive disease over the 6 months, anti‐TNF was withdrawn and they were followed up for 8 months to assess for the occurrence of flare. Serum S100 levels were measured at baseline and at the time of anti‐TNF withdrawal. Spearman's rank correlation test, Mann‐Whitney U test, Kruskal‐Wallis test, receiver operating characteristic (ROC) curve, and Kaplan‐Meier survival analyses were used to assess the relationship between serum S100 levels and maintenance of clinically inactive disease and occurrence of disease flare after anti‐TNF withdrawal.
Results
Over the 6‐month initial phase with anti‐TNF therapy, the disease state reverted from clinically inactive to clinically active in 24 (18%) of the 130 evaluable patients with polyarticular‐course JIA; following anti‐TNF withdrawal, 39 (37%) of the 106 evaluable patients experienced a flare. Serum levels of S100A8/A9 and S100A12 were elevated in up to 45% of patients. Results of the ROC analysis revealed that serum S100 levels did not predict maintenance of clinically inactive disease during anti‐TNF therapy nor did they predict disease flare after treatment withdrawal. Elevated levels of S100A8/A9 were not predictive of the occurrence of a disease flare within 30 days, 60 days, 90 days, or 8 months following anti‐TNF withdrawal, and elevated S100A12 levels had a modest predictive ability for determining the risk of flare within 30, 60, and 90 days after treatment withdrawal. Serum S100A12 levels at the time of anti‐TNF withdrawal were inversely correlated with the time to disease flare (r = −0.36).
Conclusion
Serum S100 levels did not predict maintenance of clinically inactive disease or occurrence of disease flare in patients with polyarticular‐course JIA, and S100A12 levels were only moderately, and inversely, correlated with the time to disease flare.
To determine the elapsed time while receiving aggressive therapy to the first observation of clinically inactive disease (CID), total duration of CID and potential predictors of this response in a ...cohort of children with recent onset of polyarticular juvenile idiopathic arthritis (poly-JIA).
Eighty-five children were randomized blindly to methotrexate (MTX), etanercept, and rapidly tapered prednisolone (MEP) or MTX monotherapy and assessed for CID over 1 year of treatment. Patients who failed to achieve intermediary endpoints were switched to open-label MEP treatment.
Fifty-eight (68.2%) of the 85 patients achieved CID at 1 or more visits including 18 who received blinded MEP, 11 while receiving MTX monotherapy, and 29 while receiving open-label MEP. Patients starting on MEP achieved CID earlier and had more study days in CID compared to those starting MTX, but the differences were not significantly different. Patients given MEP (more aggressive therapy) earlier in the disease course were statistically more likely to have a higher proportion of followup visits in CID than those with longer disease course at baseline. Those who achieved American College of Rheumatology Pediatric 70 response at 4 months had a significantly greater proportion of followup visits in CID, compared to those who failed to achieve this improvement (p < 0.0001). Of the 32 patients who met criteria for CID and then lost CID status, only 3 fulfilled the definition of disease flare.
Shorter disease duration prior to treatment, a robust response at 4 months, and more aggressive therapy result in a higher likelihood and longer duration of CID in patients with poly-JIA. The original trial from which data for this analysis were obtained is registered on www.clinicaltrials.gov NCT 00443430.
To identify targets for improving mental healthcare of adolescents with systemic lupus erythematosus (SLE) by assessing current practices and perceived barriers for mental health intervention by ...pediatric rheumatology clinicians.
Members of the Childhood Arthritis and Rheumatology Research Alliance (CARRA) completed a Web-based survey assessing current mental health practices, beliefs, and barriers. We examined associations between provider characteristics and the frequency of barriers to mental health screening and treatment using multivariable linear regression.
Of the 375 eligible CARRA members, 130 responded (35%) and 119 completed the survey. Fifty-two percent described identification of depression/anxiety in adolescents with SLE at their practice as inadequate, and 45% described treatment as inadequate. Seventy-seven percent stated that routine screening for depression/anxiety in pediatric rheumatology should be conducted, but only 2% routinely used a standardized instrument. Limited staff resources and time were the most frequent barriers to screening. Respondents with formal postgraduate mental health training, experience treating young adults, and practicing at sites with very accessible mental health staff, in urban locations, and in Canada reported fewer barriers to screening. Long waitlists and limited availability of mental health providers were the most frequent barriers to treatment. Male clinicians and those practicing in the Midwest and Canada reported fewer barriers to treatment.
Pediatric rheumatology clinicians perceive a need for improved mental healthcare of adolescents with SLE. Potential strategies to overcome barriers include enhanced mental health training for pediatric rheumatologists, standardized rheumatology-based mental health practices, and better integration of medical and mental health services.
