Abstract
This paper aims to compare the cellular immune response to the SARS-CoV2 BNT162b2 vaccine of pediatric patients with autoimmune inflammatory rheumatic disease (pAIIRD) and healthy controls. A prospective longitudinal study was conducted between April 2021 to December 2022 at the Tel Aviv Medical Center. Children<18 years, with pediatric-onset AIIRD and healthy controls, who have received at least two doses of the BNT162b2 vaccine, were included. Humoral response was evaluated by serum levels of anti-SARS-CoV-2 receptor-binding domain antibodies. Cellular response was evaluated by flow cytometry, measuring IFNγ and TNFα production by CD4+ T-cells following stimulation with SARS-CoV-2 Spike peptide mix. The study included 20 pAIIRD patients and 11 controls. The mean age of participants was 12.6±2.94 years, with 58.1% females. The cellular response to the BNT162b2 vaccine was statistically similar in both groups. However, the humoral response was statistically lower in pAIIRD compared with the healthy control group. There was no statistically significant correlation between the humoral response and cellular response. During the study period, 43.75% AIIRD children and 72.7% controls had a breakthrough COVID-19 infection (p=0.48). Bivariate models examining the effect of the cellular response and presence of an AIIRD on breakthrough infections found no effect. Compared with healthy controls, pAIIRD demonstrated similar cellular responses. Patients showed reduced humoral response compared with healthy adolescents, but similar breakthrough infection rates. These findings may support the importance of the cellular response in protecting against COVID-19 infections.

Abstract
PURPOSE To facilitate claims-based research on populations with juvenile idiopathic arthritis (JIA), we sought to validate an algorithm of new medication use as a proxy for worsening JIA disease activity. METHODS Using electronic health record data from three pediatric centers, we defined new JIA medication use as (re)initiation of disease-modifying antirheumatic drugs or glucocorticoids (oral or intra-articular). Data were collected from 201 randomly selected subjects with (101) or without (100) new medication use. We assessed the positive predictive value (PPV) and negative predictive value (NPV) based on a reference standard of documented worsening of JIA disease activity. The algorithm was refined to optimize test characteristics. RESULTS Overall, the medication-based algorithm had suboptimal performance in representing worsening JIA disease activity (PPV 69.3%, NPV 77.1%). However, algorithm performance improved for definitions specifying longer times after JIA diagnosis (≥1-year post-diagnosis: PPV 82.9%, NPV 80.0%) or after initiation of prior JIA treatment (≥1-year post-treatment: PPV 89.7%, NPV 80.0%). CONCLUSION An algorithm for new JIA medication use appears to be a reasonable proxy for worsening JIA disease activity, particularly when specifying new use ≥1 year since initiating a prior JIA medication. This algorithm will be valuable for conducting research on JIA populations within administrative claims databases.

Abstract
OBJECTIVES To understand the burden associated with pediatric chronic pain (CP) on the health care system compared with other costly chronic diseases prior to subspecialty care. STUDY DESIGN In this retrospective cohort study, we assessed all-cause health care utilization and direct health care costs associated with pediatric CP (n = 91) compared with juvenile arthritis (n = 135), inflammatory bowel disease (n = 90), type 1 diabetes (n = 475) or type 2 diabetes (n = 289), anxiety (n = 7193), and controls (n = 273) 2 and 5 years prior to patients entering subspecialty care in Manitoba, Canada. Linked data from physician encounters, emergency department visits, hospitalizations, and prescriptions were extracted from administrative databases. Differences in health care utilization and direct health care costs associated with CP vs the other conditions were tested using negative binomial and zero-inflated negative binomial regression models, respectively. RESULTS After adjustment for age at diagnosis, sex, location of residence, and socioeconomic status, CP continued to be associated with the highest number of consulted physicians and subspecialists and the highest number of physician billings compared with all other conditions (P < .01, respectively). CP was significantly associated with higher physician costs than juvenile arthritis, inflammatory bowel disease, type 1 diabetes, type 2 diabetes, or controls (P < .01, respectively); anxiety was associated with the highest physician and prescription costs among all cohorts (P < .01, respectively). CONCLUSION Compared with chronic inflammatory and endocrinologic conditions, pediatric CP and anxiety were associated with substantial burden on the health care system prior to subspecialty care, suggesting a need to assess gaps and resources in the management of CP and mental health conditions in the primary care setting.

Abstract
Juvenile idiopathic arthritis is an inflammatory disease that can affect the temporomandibular joint (TMJ) and lower jaw growth. Better treatment options are needed, so this study investigated the effect of low-intensity pulsed ultrasound (LIPUS) on TMJ arthritis. Seventy-two 3-week-old male Wistar rats were in vivo microcomputed tomography (micro-CT) scanned and divided into eight groups (n = 9). These groups were Group 1-TMJ arthritis and immediate LIPUS treatment (20 min/day, 4 weeks); Group 2-immediate LIPUS treatment and no TMJ arthritis; Group 3-TMJ arthritis and no LIPUS; Group 4-no TMJ arthritis and no LIPUS; Group 5-TMJ arthritis and LIPUS treatment with a delayed start by 4 weeks; Group 6-Delayed LIPUS and no TMJ arthritis; Group 7-TMJ arthritis and no (delayed) LIPUS; and Group 8-no TMJ arthritis and no (delayed) LIPUS. Ex vivo micro-CT scanning was completed, and samples were prepared for tissue analysis. Synovitis was observed in the TMJ arthritis (collagen-induced arthritis [CIA]) groups, but the severity appeared greater in the groups without LIPUS treatment. Fibrocartilage and hypertrophic cell layer thicknesses in the CIA group without LIPUS treatment were significantly greater (p < 0.05). Proteoglycan staining appeared greater in the LIPUS groups. Immediate LIPUS treatment increased the expression of type II collagen, type X collagen, and transforming growth factor-beta 1 (TGF-β1) immunostaining, and CIA (no LIPUS) increased MMP-13, vascular endothelial growth factor, and interleukin-1 beta (IL-1β) immunostaining. LIPUS treatment prevented growth disturbances observed in the CIA groups (no LIPUS) (p < 0.005). Our results have contributed to the understanding of the uses and limitations of the CIA juvenile rat model and have demonstrated the effects of LIPUS on the TMJ and mandibular growth. This information will help in designing future studies for investigating LIPUS and TMJ arthritis, leading to the development of new treatment options for children with juvenile arthritis in their TMJs.

Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) is a very common systemic inflammatory rheumatic disorder affecting the musculoskeletal system in children below 16 years of age. Joint inflammation and tissue destruction is the prime characteristic of the disease. Along with the systemic involvement in the long joints, several studies are mentioning the increased association of temporomandibular disorders (TMDs) in JIA. This current systematic review intends to find the prevalence rate of TMD in JIA-affected individuals as compared to healthy controls. METHODS We have searched in PubMed, Scopus and Ovid SP for articles published between the timeframe 1 January 1990 and 1 June 2023. All the searched articles were subjected to the Population, Exposure, Comparison, and Outcome model (PECO) based on which inclusion or exclusion is carried out. Participants (P) are children below 18 years of age, Exposure (E) is children or adolescents with a diagnosis of JIA, Comparator is age and gender-matched healthy controls who has no JIA or any systemic disorder, Outcome (O) is the prevalence of TMD. Only the studies that evaluated TMD using diagnostic criteria for evaluation of TMD (DC/TMD) were included in the analysis. We have set the exclusion to the following reasons- diagnostic sensitivity studies, case reports, and systematic reviews. The software Review Manager Version 5.4 (Cochrane Collaboration) was used to perform the pooled analysis. We measured the risk ratio (RR) between the two groups (JIA and no JIA) for the outcome TMD. RESULTS The pooled total included subjects were 366 in this review with an established diagnosis of JIA as evaluated by DC/TMD. The overall effect of the pooled data suggests that there is a significant difference in the TMD prevalence in the JIA group when compared to the control, results suggest that TMD is more prevalent in the JIA group RR 3.86; 95% CI [2.59, 5.76]. CONCLUSION Overall, based on the data we can suggest a positive relationship between JIA and TMD, hence presence of JIA can be a risk factor for the development of TMD. The sensitivity of DC/TMD is low when compared to magnetic resonance imaging.

Abstract
Background: Juvenile idiopathic arthritis (JIA) is the most frequent chronic rheumatic disease in children. If inflammation is not adequately treated, joint damage, long-term disability, and active disease during adulthood can occur. Identifying and implementing early and adequate therapy are critical for improving clinical outcomes. The burden of JIA on affected children, their families, and the healthcare system in Spain has not been adequately assessed. The greatest contribution to direct costs is medication, but other expenses contribute to the consumption of resources, negatively impacting healthcare cost and the economic conditions of affected families. Objective: To assess the direct healthcare, indirect resource utilization, and associated cost of moderate-to-severe JIA in children in routine clinical practice in Spain. Methods: Children were enrolled in this 24-month observational, multicentric, cross-sectional, retrospective study (N = 107) if they had been treated with biologic disease-modifying anti-rheumatic drugs (bDMARDs), had participated in a previous study (ITACA), and continued to be followed up at pediatric rheumatology units at 3 tertiary Spanish hospitals. Direct costs included medication, specialist and primary care visits, hospitalizations, emergency visits or consultations, surgeries, physiotherapy, and tests. Indirect costs included hospital travel expenses and loss of caregiver working hours. Unitary costs were obtained from official sources (€, 2020). Results: Overall, children had inactive disease/low disease activity according to JADAS-71 score and very low functional disability as measured by Childhood Health Assessment Questionnaire score. Up to 94.4% of children received treatment, mainly with bDMARDs as monotherapy (84.5%). Among anti-TNFα treatments, adalimumab (47.4%) and etanercept (40.2%) were used in similar proportions. Annual mean (SD) total JIA cost was €7516.40 (€5627.30). Average cost of pharmacological treatment was €3021.80 (€3956.20), mainly due to biologic therapy €2789.00 (€3399.80). Direct annual cost (excluding treatments) was €3654.60 (€3899.00). Indirect JIA cost per family was €747.20 (€1452.80). Conclusion: JIA causes significant costs to the Spanish healthcare system and affected families. Public costs are partly due to the high cost of biologic treatments, which nevertheless remain an effective long-term treatment, maintaining inactive disease/low disease activity state; a very low functional disability score; and a good quality of life.

Abstract
BACKGROUND/OBJECTIVE Given limited information on health care and treatment utilization for juvenile idiopathic arthritis (JIA) during the pandemic, we studied JIA-related health care and treatment utilization in a commercially insured retrospective US cohort. METHODS We studied rates of outpatient visits, new disease-modifying antirheumatic drug (DMARD) initiations, intra-articular glucocorticoid injections (iaGC), dispensed oral glucocorticoids and opioids, DMARD adherence, and DMARD discontinuation by quarter in March 2018-February 2021 (Q1 started in March). Incident rate ratios (IRR, pandemic vs prepandemic) with 95% confidence intervals (CIs) were estimated using multivariable Poisson or Quasi-Poisson models stratified by diagnosis recency (incident JIA, <12 months ago; prevalent JIA, ≥12 months ago). RESULTS Among 1294 children diagnosed with JIA, total and in-person outpatient visits for JIA declined during the pandemic (IRR, 0.88-0.90), most markedly in Q1 2020. Telemedicine visits, while higher during the pandemic, declined from 21% (Q1) to 13% (Q4) in 2020 to 2021. During the pandemic, children with prevalent JIA, but not incident JIA, had lower usage of iaGC (IRR, 0.60; 95% CI, 0.34-1.07), oral glucocorticoids (IRR, 0.47; 95% CI, 0.33-0.67), and opioids (IRR, 0.44; 95% CI, 0.26-0.75). Adherence to and discontinuation of DMARDs was similar before and during the pandemic. CONCLUSIONS In the first year of the pandemic, visits for JIA dropped by 10% to 12% in commercially insured children in the United States, declines partly mitigated by use of telemedicine. Pandemic-related declines in intra-articular glucocorticoids, oral glucocorticoids, and opioids were observed for children with prevalent, but not incident, JIA. These changes may have important implications for disease control and quality of life.

Abstract
OBJECTIVE Many children with chronic musculoskeletal pain conditions experience stigma which can have negative downstream consequences. This study compares ratings of clinical pain (current pain intensity and pain interference), experimental pain (temporal summation, cold water tolerance, and cold pain intensity), and pain-related stigma among three groups of youth with rheumatic conditions. The relations among ratings of pain-related stigma and pain variables were explored. METHODS Eighty-eight youth aged 8-17 years with a diagnosis of juvenile idiopathic arthritis (JIA = 32), juvenile fibromyalgia (JFM = 31), or non-specific chronic pain (NSCP = 25) completed measures of clinical pain ratings (average 7-day pain intensity, day of assessment pain (DoA), and pain interference), experimental pain (cold pain tolerance, cold pain intensity, and temporal summation of mechanical pain), and pain-related stigma. Data analysis compared pain-related stigma and pain ratings across the three groups and examined the relations among pain-related stigma and pain ratings. RESULTS Youth with JFM reported higher ratings of clinical pain and pain-related stigma than their counterparts with NSCP or JIA. However, there were no differences in experimental pain. Pain-related stigma was associated with greater ratings of pain interference, particularly for those with JIA and NSCP. Pain-related stigma was also associated with greater average daily pain intensity but not DoA. CONCLUSION Youth with medically unexplained pain report greater stigma and worse pain than their peers; thus, robust assessment of pain in this population is necessary. Future work should longitudinally explore the impact of pain-related stigma on pain outcomes and treatment responses.

Abstract
Objectives Dentofacial deformity following juvenile idiopathic arthritis with temporomandibular joint involvement is associated with functional, aesthetic, and psychosocial impairment. Surgical treatment may involve combinations of orthognathic surgery. The aims of this retrospective study were to assess orofacial symptoms, functional and aesthetic status, and stability after orthognathic surgery. Material and Methods Nineteen patients with juvenile idiopathic arthritis of the temporomandibular joint (TMJ) and dentofacial deformities were included. All patients were treated with combinations of bilateral sagittal split osteotomy, Le Fort I and/or genioplasty, between September 10, 2007 and October 17, 2017. Analysis of patient symptoms and clinical registrations, and frontal/lateral cephalograms was performed pre- and postoperative and long-term (mean: 3.8 and 2.6 years, respectively). Results Patients experienced no changes in orofacial symptoms or TMJ function, and stable normalisation of horizontal and vertical incisal relations at long-term (horizontal overbite; vertical overbite: P < 0.05). Mandibular lengthening was achieved postoperatively (from mean 79.7 to 87.2 mm; P = 0.004) and was stable. Sella-nasion to A point (SNA) and sella-nasion to B point (SNB) angles increased postoperatively (SNA, mean 79.9° to 82.8°; P = 0.022 and SNB, mean 73.9° to 77.8°; P = 0.003), however, largely reverted to preoperative status at long-term. Conclusions Orthognathic surgery normalized incisal relations while providing stable mandibular lengthening without long-term deterioration of temporomandibular joint function or orofacial symptoms. No long-term effect on jaw advancements was observed.

Abstract
OBJECTIVE To test the association of early disease severity with grade 12 standards test performance in individuals with childhood-onset chronic rheumatic diseases (ChildCRDs), including juvenile arthritis and systemic autoimmune rheumatic diseases. METHODS We used linked provincial administrative data to identify patients with ChildCRDs born between 1979 and 1998 in Manitoba, Canada. Primary outcomes were Language and Arts Achievement Index (LAI) scores and Math Achievement Index (MAI) scores from grade 12 standards test results as well as enrollment data. The secondary outcome was enrollment in grade 12 by 17 years of age. Latent class trajectory analysis identified disease severity groups using physician visits following diagnosis. Multivariable linear regression tested the association of disease severity groups with LAI and MAI scores, and logistic regression tested the association of disease severity with age-appropriate enrollment, after adjusting for sociodemographic factors and psychiatric morbidities. RESULTS The study cohort included 541 patients, 70.1% of whom were female. A 3-class trajectory model provided the best fit; it classified 9.7% of patients as having severe disease, 54.5% as having moderate disease, and 35.8% as having mild disease. After covariate adjustment, severe disease was associated with poorer LAI and MAI scores but not with age-appropriate enrollment. CONCLUSION Among patients with ChildCRDs, those with severe disease performed more poorly on grade 12 standards tests, independent of sociodemographic and psychiatric risk factors. Clinicians should work with educators and policy makers to advocate for supports to improve educational outcomes of patients with ChildCRDs.

Abstract
BACKGROUND Some juvenile idiopathic arthritis (JIA) patients have a familial aggregation of the disease, and a few have been found to have a juvenile arthritis (JA) phenotype caused by a genetic mutation. JA due to LACC1 defects is a rare condition and it was never reported in China. METHODS The clinical and molecular characteristics of a child with LACC1 gene mutation-related juvenile arthritis, diagnosed by high-throughput sequencing in Wuhan children's Hospital in 2021 were analyzed retrospectively; The literature and database were reviewed to summarize the clinical data and genotype characteristics of patients with JA caused by LACC1 gene mutation. RESULTS Here, we report a 19-month-old Chinese male patient who presented with bilateral limb edema without a history of fever. Laboratory tests showed had moderate anemia and signs of inflammation: hemoglobin of 76 g/L, white blood cell count of 20.53 × 109 , and platelet count of 1194 × 109 ; MRI showed the patient had synovitis and tenosynovitis in bilateral hands and wrists. Whole-exome sequencing (WES) detected compound heterozygous variants, novel c.446_449dupTAAA and c.889T>C, in the LACC1 gene. Of the 52 patients reported in the literature (including this case), 38.9% had clinical symptoms of systemic juvenile idiopathic arthritis (sJIA), which tended to be caused by loss-of-function (LOF) mutation. Findings in this study expanded the spectrum of pathogenic variants and reveal the phenotypic heterogeneity of LACC1-JA. CONCLUSIONS Our study reported a rare case of juvenile arthritis, which is due to the compound heterozygous mutation of LACC1, including a new novel frameshift mutation c.446_449dupTAAA, and LACC1 C297R variant causes disease by potentially modifying the local conformation of proteins. The clinical and genetic findings in our study show that LACC1-JA is highly heterogeneous, and gene testing is required for juvenile arthritis patients with a high inflammatory response at a young onset age.

Abstract
OBJECTIVES Childhood chronic pain conditions are common and vulnerable to stigma. Adolescents with chronic primary pain experience diagnostic uncertainty and describe pain-related stigma experiences across multiple social contexts. Juvenile idiopathic arthritis (JIA) is a childhood autoimmune, inflammatory condition with associated chronic pain, but with well-defined diagnostic criteria. The current study examined pain-related stigma experiences in adolescents with JIA. METHODS Four focus groups of 3-7 adolescents with JIA (N = 16), ages 12-17 (Mage = 15.42, SD = 1.82), and parents (N = 13) were conducted to examine experiences of, and reaction to, pain-related stigma. Patients were recruited from an outpatient pediatric rheumatology clinic. Focus group length ranged from 28 to 99 minutes long. Two coders used directed content analysis resulting in 82.17% inter-rater level of agreement. RESULTS Adolescents with JIA described pain-related stigma experiences predominantly from school teachers and peers, and less from medical providers (e.g., school nurses), and family members after a diagnosis. The primary categories that emerged were (1) Felt Stigma, (2) Internalized Stigma, (3) Anticipatory Stigma/Concealment, and (4) Contributions to Pain-Related Stigma. A common experience of pain-related stigma was the perception by others that the adolescent was too young to have arthritis. CONCLUSIONS In common with adolescents with unexplained chronic pain, our findings indicate that adolescents with JIA experience pain-related stigma in certain social contexts. Diagnostic certainty may contribute to greater support among medical providers and within families. Future research should investigate the impact of pain-related stigma across childhood pain conditions.

Abstract
Background and Objectives: Systemic juvenile idiopathic arthritis (sJIA) is a distinctive JIA subtype with mostly nonspecific systemic clinical features, which can be a diagnostic challenge. This study aimed to analyze our experience with sJIA in Latvia for twelve years: assessing clinical and epidemiological characteristics, the efficacy of therapy, and disease outcomes, including the development of macrophage activation syndrome (MAS). Materials and methods: This is a descriptive study in which we conducted a retrospective case review of all patients with sJIA diagnosis admitted to the only pediatric tertiary centre in Latvia during the period 2009-2020. Results: sJIA was diagnosed in 35 patients with a mean annual incidence rate of 0.85 patients per 100,000 children. Major clinical signs at the first visit were: fever, rash, arthritis, and lymphadenopathy. Almost half of the patients, 48.5%, had a monocyclic disease course, and only 20% of patients had persistent disease. MAS developed in 28.6% of patients. Biological therapy was administered to 48.6% of patients, mostly by tocilizumab, which induced remission in 75% after one year, and in 81.2% after two years without any serious therapy-related complications. In our study, none of the patients had interstitial lung disease, drug reaction with eosinophilia and systemic symptoms (DRESS)-like syndrome, or fatal disease. Conclusions: The incidence and clinical characteristics of sJIA correlate with the literature findings, although MAS was more common than described in other studies. There is a tendency for the persistent disease to decrease with the use of biological therapy. Tocilizumab is an efficient choice of treatment with a good safety profile.

Abstract
OBJECTIVE To evaluate microRNA expression in synovial fluid (SF), plasma, and leukocytes from patients with juvenile idiopathic arthritis (JIA). METHODS MicroRNA expression in pooled JIA plasma and SF was assessed by absolute quantitative droplet digital PCR array. The results were validated in individual patient samples. MicroRNA content in leukocytes and extracellular vesicles was evaluated by real-time PCR in JIA blood and SF. Blood microRNA expression was compared with healthy controls (HCs). Principal component analysis was used to profile JIA plasma and SF microRNAs, and the potential biological consequences of microRNA dysregulation were investigated by pathway analysis. RESULTS MiR-15a-5p and miR-409-3p levels were higher in JIA plasma than in HC plasma. JIA SF contained elevated levels of miR-21-5p, miR-27a-3p, miR-146b-5p, miR-155-5p, and miR-423-5p, and decreased miR-192-5p and miR-451a, compared to JIA plasma. Extracellular vesicle analysis demonstrated variable encapsulation among selected microRNAs, with only miR-155-5p being represented substantially in extracellular vesicles. SF leukocytes also had higher expression of miR-21-5p, miR-27a-3p, miR-146b-5p, and miR-155-5p, and lower expression of miR-409-3p and miR-451a, relative to blood. No differences were observed between JIA and HC blood leukocytes. Clusters of microRNAs were commonly altered in JIA joint fluid and leukocytes compared to JIA blood samples. In silico analysis predicted that differentially expressed microRNAs in JIA target the transforming growth factor (TGF)-β pathway. CONCLUSION The expression of multiple microRNAs is dysregulated in JIA both locally and systemically, which may inhibit the TGF-β pathway. These findings advance our knowledge of JIA immunopathogenesis and may lead to the development of targeted therapies.

Abstract
Introduction Dendritic cells (DC) are crucial for initiating and shaping immune responses. So far, little is known about the functional specialization of human DC subsets in (local) inflammatory conditions. We profiled conventional (c)DC1, cDC2 and monocytes based on phenotype, transcriptome and function from a local inflammatory site, namely synovial fluid (SF) from patients suffering from a chronic inflammatory condition, Juvenile Idiopathic Arthritis (JIA) as well as patients with rheumatoid arthritis (RA). Methods Paired PB and SF samples from 32 JIA and 4 RA patients were collected for mononuclear cell isolation. Flow cytometry was done for definition of antigen presenting cell (APC) subsets. Cell sorting was done on the FACSAria II or III. RNA sequencing was done on SF APC subsets. Proliferation assays were done on co-cultures after CD3 magnetic activated cell sorting (MACS). APC Toll-like receptor (TLR) stimulation was done using Pam3CSK4, Poly(I:C), LPS, CpG-A and R848. Cytokine production was measured by Luminex. Results cDC1, a relatively small DC subset in blood, are strongly enriched in SF, and showed a quiescent immune signature without a clear inflammatory profile, low expression of pathogen recognition receptors (PRRs), chemokine and cytokine receptors, and poor induction of T cell proliferation and cytokine production, but selective production of IFNλ upon polyinosinic:polycytidylic acid exposure. In stark contrast, cDC2 and monocytes from the same environment, showed a pro-inflammatory transcriptional profile, high levels of (spontaneous) pro-inflammatory cytokine production, and strong induction of T cell proliferation and cytokine production, including IL-17. Although the cDC2 and monocytes showed an overlapping transcriptional core profile, there were clear differences in the transcriptional landscape and functional features, indicating that these cell types retain their lineage identity in chronic inflammatory conditions. Discussion Our findings suggest that at the site of inflammation, there is specific functional programming of human DCs, especially cDC2. In contrast, the enriched cDC1 remain relatively quiescent and seemingly unchanged under inflammatory conditions, pointing to a potentially more regulatory role.

Abstract
There is limited research regarding management of temporomandibular disorders (TMD) in adolescents with imaging signs of juvenile idiopathic arthritis (JIA). An 11-year-old girl presented to a hospital-based chiropractor for evaluation of a 1.5-year history of unilateral temporomandibular joint (TMJ) pain and trismus. Previously, pediatric rheumatologists diagnosed JIA after contrast-enhanced magnetic resonance imaging revealed edema, effusion, and bilateral anterior disc displacement, and recommended methotrexate, corticosteroid injection, and arthrocentesis. The chiropractor questioned the JIA diagnosis, instead relating symptoms to a mechanical TMD/disc origin. Manual therapy, TMJ exercises, and acupuncture improved TMJ pain and opening. Invasive medical JIA interventions were avoided without long-term recurrence, further questioning the preceding JIA diagnosis. The success of this case suggests that stepped care, beginning with conservative treatment, has value for adolescents with TMD suspect for JIA. Integration of chiropractors and acupuncturists into healthcare institutions may facilitate this care model by affording nonpharmacologic interventions earlier in patient care.

Abstract
Juvenile arthritis (JA) is an autoimmune condition affecting children. We used the 2017 National Inpatient Sample (NIS) to evaluate the impact of JA in the United States. The admission data were converted to weighted form and patients between the ages of 0 and 18 (inclusive) were used in our study. 560 weighted cases were found in 2017. It was more common in females than males (340 females, 220 males), Whites (235 cases), and Medicaid covered 61.6% of all patients with JA (345 cases). The total hospital charges were $25,147,389 while the mean length of stay (LOS) was 4.55 days. The highest number of cases was reported in April 2017.

Abstract
BACKGROUND/OBJECTIVE The importance of patient-reported outcomes, like the Patient-Reported Outcomes Measurement Information System (PROMIS) measures, is increasingly recognized both in clinical care and in research. While "short forms" have been studied in juvenile idiopathic arthritis (JIA), study of PROMIS computer adaptive tests (CATs) in JIA is limited. This cross-sectional study evaluates whether PROMIS CATs correlate with disease activity in patients with JIA. METHODS A convenience sample of patients with JIA (N = 44) was recruited from a single center. Patients and parents completed pediatric and parent proxy PROMIS CATs. Disease activity was evaluated using the Juvenile Arthritis Disease Activity Score in 71 joints (JADAS-71) and the Childhood Health Assessment Questionnaire (CHAQ). Correlation of the CAT T scores with disease activity was assessed using Spearman correlation coefficients. RESULTS Forty-four of 80 eligible subjects (29 patients and 15 parents) completed all or some PROMIS CATs. Pain interference and mobility CATs correlated moderately with JADAS-71. Nearly all correlations with the JADAS-71 were weakened when the patient global was removed. Pain interference, mobility, and fatigue were strongly correlated with the CHAQ. Among parent proxy CATs, only mobility and depressive symptoms correlated strongly with the CHAQ. CONCLUSIONS Only pain interference and mobility PROMIS CATs showed strong correlation with standard disease activity measures in JIA, and nearly all correlations were weakened when the patient global was removed. Correlations of the CATs with the CHAQ were stronger than correlations with the JADAS-71, indicating that although the CHAQ is no longer routinely used it may be a better measure of health-related quality of life in routine clinical care.

Abstract
Juvenile spondyloarthritis (JSpA) refers to a diverse spectrum of immune-mediated inflammatory arthritides whose onset occurs in late childhood and adolescence. Like its adult counterpart, JSpA is typified by a strong association with human leukocyte antigen-B27 (HLA-B27) and potential axial involvement, while lacking rheumatoid factor (RF) and distinguishing autoantibodies. A characteristic manifestation of JSpA is enthesitis (inflammation of insertion sites of tendons, ligaments, joint capsules or fascia to bone), which is commonly accompanied by bone resorption and new bone formation at affected sites. In this Review, advances in the role of HLA-B27, enthesitis and its associated osteoproliferation in JSpA pathophysiology and treatment options will be discussed. A deeper appreciation of how these elements contribute to the JSpA disease mechanism will better inform diagnosis, prognosis and therapy, which in turn translates to an improved quality of life for patients.

Abstract
BACKGROUND/OBJECTIVE Patients with juvenile idiopathic arthritis (JIA) often present with signs and symptoms suggestive of serious bacterial infection (SBI). Procalcitonin (PCT) is a biomarker that is elevated in SBI. We conducted a comparative cohort study to test the hypothesis that PCT levels will differ between active JIA, quiescent JIA, and bacteremic patients and healthy controls. METHODS From October 2016 to May2018, consecutive children 6 months to 18 years of age with (a) active untreated JIA, (b) quiescent JIA, and (c) healthy elective presurgical candidates were recruited from clinics at a musculoskeletal specialty hospital. Juvenile idiopathic arthritis was defined according to the International League of Associations for Rheumatology criteria. Clinical data and serum samples meeting the same criteria were included from a prior study. Consecutive bacteremic patients were identified over the same period. Procalcitonin and other common measures of inflammation were measured. Descriptive statistics and univariate logistic analyses were performed. RESULTS Ninety-two study subjects were recruited. Erythrocyte sedimentation rate, C-reactive protein (CRP), and PCT levels were all elevated in bacteremic patients in comparison to the other groups. Erythrocyte sedimentation rate and CRP both had wide ranges that overlapped between groups; however, the PCT concentration was 0.15 μg/mL or greater in 1 of 59 patients with JIA, whereas it was 0.15 μg/mL or less in only 1 bacteremic patient. CONCLUSIONS Our study indicates that serum erythrocyte sedimentation rate, CRP, and PCT levels are all biomarkers that can be used to distinguish SBI versus active JIA at presentation. However, PCT is the most accurate, with the least overlap between patients with infection and noninfectious inflammatory arthritis. This finding can help clinicians direct therapy.

Abstract
OBJECTIVE Forming and maintaining romantic relationships is an important developmental task in adolescence and young adulthood. This scoping review seeks to explore how young people with long-term physical health conditions understand and experience romantic relationships. METHODS Using Arksey and O'Malley's scoping review framework, a systematic search of five databases was conducted (PsychINFO, Cinahl, MEDLINE, Embase, and Web of Science). Studies were eligible for inclusion in the review if they were published in peer-reviewed journals, used primary data collection methods, and adopted quantitative, qualitative, or mixed-methods approaches to study romantic relationships in 11-25 year olds with long-term physical health conditions. Using a data extraction form, data pertaining to demographic characteristics of young people with long-term physical health conditions and relationship engagement were extracted from eligible papers. RESULTS Searches returned 4645 papers after duplicate removal, with a two-stage screening process resulting in 111 full-text papers being reviewed. Thirty-three eligible papers were included across a range of long-term physical health conditions. Findings identified that living with a long-term physical health condition impacted young people's perceptions and experiences of romantic relationships across the relationship lifespan, from envisaging future relationships, to forming relationships, and sustaining relationships. Issues around body confidence and self-esteem were identified as challenging in terms of perceptions and experiences of romantic relationships. CONCLUSIONS Findings demonstrate that young people wish to engage with romantic relationships, yet many report particular challenges associated with forming and sustaining relationships due to the constraints of their condition and treatment. Future research should consider nonheterosexual relationships.

Abstract
Juvenile idiopathic arthritis can affect the temporomandibular joint (TMJ) can cause growth disturbances of the lower jaw (mandible). The collagen-induced arthritis (CIA) juvenile rat model may be an appropriate model for studying how juvenile arthritis affects this joint during growth. However, studies using this animal model to investigate TMJ arthritis are limited. To validate an animal model for studying TMJ arthritis in growing rats, our study aimed to investigate the changes in mandibular growth and expression of proteins and cytokines in the mandibular condyle of CIA juvenile rat TMJs. A total of 27 male Wistar rats (3 weeks old) were scanned with microcomputed tomography (MicroCT) and divided into three groups (n = 9); CIA was induced in each TMJ in the CIA group, the Saline group received saline injections (sham injections) into their TMJs, and the Healthy group remained untreated (no TMJ injections) as negative controls. After 4 weeks, our results show that mandibular growth was significantly reduced in the CIA group compared with the Saline group (p < 0.01). There was no difference in mandibular growth between the two control groups (Saline and Healthy). Inflamed synovial tissue, cartilage invaginations, and lipid accumulation were observed in the CIA TMJs. Toluidine blue staining revealed decreased proteoglycan production in the CIA cartilage. In addition, immunohistochemistry revealed that type II collagen expression decreased, interleukin-1β expression increased, and matrix metalloproteinase-13 expression increased in the CIA TMJs in comparison with the two control groups (Saline and Healthy). Immunostaining of tumor necrosis factor-α (TNF-α) was quantified and we showed that TNF-α expression was significantly greater in the CIA cartilage compared with both control groups (p < 0.05), and there was no difference in TNF-α expression between the Saline and Healthy groups. This CIA juvenile rat model of TMJ juvenile arthritis shows that CIA reduced mandibular growth and induced degenerative changes in TMJ condylar cartilage. This new information will help to understand the pathogenesis involved in CIA in juvenile rat TMJs for this animal model to be used in research investigating new therapeutics to treat TMJ juvenile arthritis. Impact statement In this study, the effects of collagen-induced arthritis (CIA) on the temporomandibular joint (TMJ) using a juvenile rat model were investigated. Our results showed that local injection of CIA in the TMJ significantly reduced mandibular growth and caused degenerative changes in condylar cartilage. This information helps to validate this animal model for studying the effect of arthritis in TMJs in growing rats. This model has the potential to be used in future studies to evaluate possible therapies for TMJ arthritis.

Abstract
OBJECTIVES To determine whether there is an association between adverse childhood experiences (ACEs) and childhood-onset arthritis, comparing youth with arthritis to both healthy youth and youth with other acquired chronic physical diseases (OCPD); and to examine whether ACEs are associated with disease-related characteristics among children with arthritis. STUDY DESIGN In a cross-sectional analysis of data from the 2016 National Survey of Children's Health we examined whether ACEs were associated with having arthritis vs either being healthy or having a nonrheumatologic OCPD. ACE scores were categorized as 0, 1, 2-3, ≥4 ACEs. Multinomial logistic regression models examined associations between ACEs and health status while adjusting for age, sex, race/ethnicity, and poverty status. Among children with arthritis, associations between ACEs and disease-related characteristics were assessed by Pearson χ2 analyses. RESULTS Compared with children with no ACEs, children with 1, 2-3, and ≥4 ACEs had an increased odds of having arthritis vs being healthy (adjusted OR for ≥4 ACEs, 9.4; 95% CI, 4.0-22.1) and vs OCPD (adjusted OR for ≥4 ACEs, 3.7; 95% CI-1.7, 8.1). Among children with arthritis, ACEs were associated with worse physical impairment. CONCLUSIONS Children with higher numbers of ACEs are more likely to have arthritis, when arthritis status is compared either with being healthy or with having OCPD. Further studies are needed to determine the direction of the association between ACEs and childhood arthritis, its impact on disease course, and potential intervention targets that might mitigate these effects.

Abstract
The aim of this report is to present a patient with juvenile arthritis, condylar resorption, and residual facial asymmetry treated with orthognathic surgery and unilateral joint replacement with a full three-dimensional computer-aided design and computer-aided manufacture (CAD-CAM) temporomandibular joint (TMJ) prosthesis, including an increase in the left ramus and mandibular angle to achieve facial symmetry. The patient, a 30-year-old male, came to our department for orthosurgical treatment. The patient had been receiving treatment for juvenile arthritis for 15 years; at facial level, he had a chin deviation of 12 mm from the facial midline, maxillary retrusion, and Angle Class III. The computed tomography revealed a reduced height of the left condyle and a significant difference in the morphology of the mandibular ramus and angle. Using CAD-CAM technology and additive manufacturing, a TMJ prosthesis was produced, through the use of the mirror image, orthognathic surgery was realized using the right side as “esthetic side” with suitable shape and angulation. The prosthesis was created, and this was taken to the surgery. The surgery was performed without problems, a mouth opening of 35 mm and absence of pain were noted after 12 months of follow-up. The surgery remained stable, and facial symmetry was restored. In conclusion, it is viable to develop a TMJ prosthesis by CAD-CAM that includes esthetic modifications to the face; prospective and clinical studies must be conducted to confirm protocols. Level of Evidence: V.

Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) affecting temporomandibular joints (TMJ) in growing patients results in maxillofacial deformities, especially if only one condyle has been affected by the rheumatic disease. Mandibular hypoplasia is the most common issue and it may be associated with maxillary hypoplasia. The aim of this retrospective case-control study is to evaluate the effects of rapid maxillary expansion (RME) in these patients. METHODS 25 growing patients affected by maxillary hypoplasia, currently in a quiescent phase of JIA for at least one year and monolateral involvement of the TMJs, were treated with RME. Data gathered from posteroanterior and lateral cephalograms before and after 1 year from RME were compared to those of 25 non-JIA controls. RESULTS Nasal cavity width, maxillary width and upper and lower intermolar width statistically increased. Maxillary and mandibular symmetry indexes presented a statistically significant increase, so did the skeletal class. No signs or symptoms of TMJ activity of JIA occurred according to Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) criteria. No difference was found when comparing JIA and non-JIA patients apart from the better improvement of several mandibular symmetry indexes in the affected TMJ side of JIA patients. This event is allegedly due to a worse baseline asymmetry in JIA patients that underwent a bigger relative improvement after treatment. CONCLUSIONS Results suggest that solving maxillary hypoplasia and, therefore, premature contacts are likely to have allowed mandibular repositioning and condylar growth. RME is a safe and effective solution that can substantially improve maxillary and mandibular symmetry in growing patients affected by JIA with TMJ involvement.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common chronic inflammatory rheumatism in childhood; microRNAs (miRNAs) have been proposed as diagnostic biomarkers. Although joints are the primary targets for JIA, a synovial fluid-based miRNA signature has never been studied. We aim to identify miRNA biomarkers in JIA by comparing synovial fluid and serum samples from children with JIA and K. kingae septic arthritis (SA). With next-generation high-throughput sequencing, we measured the absolute levels of 2083 miRNAs in synovial fluid and serum from an exploratory cohort of children and validated differentially expressed miRNAs in a replication study by using RT-qPCR. We identified a 19-miRNA signature only in synovial fluid samples that was significantly deregulated, with at least 2-fold change in expression, in JIA versus SA (p < 0.01). The combination of miR-6764-5p, miR-155, and miR-146a-5p expression in synovial fluid yielded an area under the receiver operating characteristic curve of 1 (95% CI 0.978 to 1), thereby perfectly differentiating JIA from SA in children. We propose, for the first time, a synovial fluid-specific miRNA signature for JIA and associated signaling pathways that may indicate potential biomarkers to assist in the classification and differential diagnosis of JIA and help in understanding JIA pathogenesis.

Abstract
Juvenile idiopathic arthritis is a common rheumatic disease that presents as chronic childhood arthritis. JIA is considered a multifactorial disease that may result from diverse genetic and environmental risk factors. A minority of the population-attributable risk of JIA is estimated to be due to familial factors. Thus, non-genetic or environmental factors likely account for a majority of the risk of developing JIA. Yet, while substantial data have linked environmental factors to the development of rheumatoid arthritis, similar evidence regarding JIA is sparse. This narrative review provides updates on recent literature about environmental factors that might influence the risk of developing JIA, including studies about potentially beneficial and harmful influences as well as factors with unclear effects.

Abstract
Purpose: To describe health care resource utilization (HCRU) and costs among patients with juvenile idiopathic arthritis (JIA) compared to patients without JIA and to describe treatment patterns among JIA patients who initiated biologic and non-biologic disease-modifying antirheumatic drugs (DMARDs). Patients and methods: The IBM MarketScan® Commercial Database was used to identify patients aged 2-17 years with a new JIA diagnosis (index date) and 12 months continuous enrollment pre- and post-diagnosis from 2008 to 2016. JIA patients were matched to non-JIA patients on age, gender, region, and health plan type. Patients with other rheumatic or autoimmune conditions were excluded. Receipt of a biologic and/or non-biologic was evaluated on or after the new JIA diagnosis. Results: A total of 3,815 JIA patients were matched to 11,535 non-JIA patients (mean age 10.0 [SD=4.5], 69% female). Average total costs were greater for JIA patients than non-JIA controls ($18,611 [SD=$42,104; median=$8,189] versus $2,203 [SD=$9,309; median=$649], p<0.001). Outpatient pharmacy costs were 33.6% of the total costs among JIA patients compared to 18.4% among non-JIA patients (p<0.001). The proportion of inpatient cost (11.4% versus 14.3%, p<0.001) and outpatient costs (55% versus 67.4%, p<0.001) of total costs was lower among JIA patients compared to non-JIA patients. Patients with 12 months of continuous enrollment post-treatment initiation (n=2,014) were classified as non-biologic only (n=734), biologic only (n=873), and both biologic and non-biologic (n=407) users. Among biologic and non-biologic users, 41.1% and 56.8% were persistent on their index medication for 12 months. Of patients treated with a biologic only, TNF inhibitors (TNFi) comprised 87.1% of the total treatment costs. Conclusion: JIA is associated with increased costs and utilization in every HCRU category compared to matched non-JIA patients. While JIA-related costs varied by treatment cohort, patients on biologic DMARDs had substantially higher costs than patients on non-biologic DMARDs and fewer than one-half were persistent at 12 months after biologic initiation.

Abstract
Background: Juvenile idiopathic arthritis (JIA) is an inflammatory autoimmune disease that can cause severe impairment and disability. Exercise is recommended to preserve joint mobility and function. Our objectives were to assess the safety, feasibility, and effects of slow speed resistance exercise in children with polyarticular JIA. Methods: Patients were recruited from a pediatric rheumatology clinic at an urban hospital and randomized to exercise or control groups. In the intervention group, slow speed resistance exercise with individualized instruction by a certified trainer was performed 1-2 times per week for 12 weeks. The control group performed home-based aerobic exercise 3 days per week for 12 weeks. Pre and post-body composition measurements by dual-energy X-ray absorptiometry; aerobic fitness by peak oxygen uptake during cycle ergometry; isometric muscle strength; and quality of life measures were obtained. Results: In the exercise group, 9/17 (53%) completed any exercise training. Of these nine subjects, five (55%) completed all 12 weeks of the protocol. In the control group, 8/16 (50%) reported compliance with the recommended aerobic exercise training at least one time per week. Only 2 subjects (12%) reported exercising more than once per week. There was no significant difference between pre- and post-measurements in any category in the exercise group. There was also significantly elevated body fat in both groups with only 17% in the control group and 23% in the exercise group meeting recommended <30% total body fat levels. Conclusions: Children with JIA participated safely in this resistance exercise protocol. The exercise was well-tolerated with no serious adverse events noted. While individual subjects reported improvement in fatigue and improved energy, there was no statistical difference in pre- and post-exercise measures of body composition or quality of life. Identifying ways to improve adherence and encourage exercise in children with JIA is important.

Abstract
Background Young people living with juvenile idiopathic arthritis (JIA) face a number of communication barriers for achieving optimal health as they transition from pediatric care into adult care. Despite growing interest in mobile or wireless technologies to support health (mHealth), it is uncertain how these engagement tools might support young people, their families, and care teams to optimize preference-based treatment strategies. Objective This study aims to examine how an mHealth patient support system (mPSS) might foster partnership between young people living with JIA, their families, and care teams. Methods Semistructured interviews with young people (5-15 years old), their families, and JIA care teams were conducted using researcher-developed interviews guides. Transcribed data were qualitatively analyzed using conventional content analysis. Results We conducted semistructured interviews with 15 young people, their parents, and 4 care team members. Content analysis revealed the potential of an mPSS to support productive dialogue between families and care teams. We identified four main themes: (1) young people with JIA face communication challenges, (2) normalizing illness through shared experience may improve adherence, (3) partnership opens windows into illness experiences, and (4) readiness to engage appears critical for clinic implementation. Conclusions A human-centered mPSS design that offers JIA patients the ability to track personally relevant illness concerns and needs can enhance communication, generate consensus-based treatment decisions, and improve efficiency and personalization of care. Technology that supports continuous learning and promotes better understanding of disease management may reduce practice burden while increasing patient engagement and autonomy in fostering lasting treatment decisions and ultimately supporting personalized care and improving outcomes.

Abstract
BACKGROUND Deformation of the mandibular condyle can be associated with anterior disk displacement (ADD) or involvement of the temporomandibular joint (TMJ) by juvenile idiopathic arthritis (JIA). Diagnostic differentiation is critical for proper management. OBJECTIVES To compare morphology and inflammation between TMJs with ADD and JIA. METHODS Retrospective assessment of contrast-enhanced TMJ MRI in 18 adolescents (15 female, mean age 15.1 ± 1.9 years) with ADD and age- and gender-matched patients with JIA. Articular disk findings, inflammatory signs and osseous morphology were compared. RESULTS In the ADD group, 31 of 36 disks were displaced. In total, 28 of 31 displaced disks showed thickening of the bilaminar zone. In JIA patients, the disks were mainly flattened (19/36), centrally perforated (12/36) and/or anteriorly displaced (2/36). In total, 19 of 31 TMJs with ADD showed various degrees of inflammation, with joint effusion, synovial thickening and joint enhancement not significantly different from JIA patients. Osseous deformity was present in 27 of 31 TMJs with ADD, with frequent erosions in both groups (ADD 25/31; JIA 32/36, P = 0.55) but lower grades of condylar and temporal bone flattening than in JIA (P ≤ 0.001). Glenoid fossa depth was preserved in 28 of 31 joints with ADD and decreased in 26 of 36 joints with JIA (P < 0.0001). Mandibular ramus height was decreased in both groups. CONCLUSION In adolescents, inflammatory signs are common MRI findings in symptomatic TMJs with ADD and thus should not be considered diagnostic for JIA involvement. In this cohort, both entities had high rates of condylar deformity, while TMJs with ADD showed a better-preserved and often normal shape of the glenoid fossa.

Abstract
Juvenile arthritis with unknown disease etiology is also known as juvenile idiopathic arthritis. Symptoms include joint pain, swelling, and stiffness, and standard treatment involves immunosuppressant medication. Here we present a case of juvenile idiopathic arthritis with severe malnutrition and worsening of symptoms, which restrained a nine-year-old girl to a wheelchair with minimal movement capacity and low energy during standard immunosuppressant therapies over the course of three years. Our innovative Pathogen Blood Test combining cytology-based microscopy and genetic analysis using a pan-fungal primer assay and sequencing identified a systemic fungal infection with Sagenomella species, closely related to Aspergillus, and a soil-dwelling highly pathogenic fungus, which had previously been linked to a fatal veterinary case of arthritis and malnutrition. Our test results encouraged a radical change of the patient's treatment plan, including cessation of the regular immunosuppressants, including steroids, over six months. The patient made a progressive recovery, including complete reversion of the previously swollen and painful joints, development of a good appetite, and return to liveliness. Within the year of change from immunosuppressants to immune-supportive integrative nutritional therapies, including regular intravenous vitamin C, and oral vitamin D, as well as gentle aqua- and physiotherapy, the patient started to gain weight including muscle mass and regained strength and movement in the hands, arms, and legs. She was able to walk again within 18 months. Her mood and energy levels continued to improve and she was able to return to school full-time.

Abstract
Purpose To understand the experience of adolescent systemic juvenile idiopathic arthritis (SJIA) patients and those of their parents based on their social media posts. Methods English language posts related to SJIA, Still’s disease, or juvenile arthritis were collected and analyzed. Results In total, 71 posts created between 2009 and 2015 on 15 websites were identified in November 2015. Of the 32 unique authors, 17 were SJIA patients aged 13–20 years (40 posts), 7 were mothers of SJIA patients (12 posts), and 8 patients had unspecified forms of juvenile arthritis (19 posts). Many patients posted about similar diagnostic experiences marked by 5 phases: 1) early prediagnosis: pain and fatigue overlooked until crisis occurred, 2) first misdiagnosis: doctors talked about “growing pains” and psychosocial problems (“fake pains” to avoid school), 3) second misdiagnosis: severity acknowledged, but diagnosed as leukemia or another cancer, 4) tests: tests leading to diagnosis and treatment conducted, and 5) cognitive identity: patient accepted the diagnosis and its implications. Many adolescent patients, looking back at disease onset in their childhood, described themselves as a “sleeping child” rather than the typical active child. Several patients tried to hide their illness from friends, but expressed concerns openly online. Many patients described SJIA as a powerful external enemy, using terms like “bulldozer,” “dragon,” and “monster.” Many posts from patients and their mothers used superhero language/imagery to help “fight” SJIA. Some patients also posted about the risk of death. Conclusion Although most adolescent SJIA patients openly posted about the difficulties of their disease online, they made efforts to hide their disease in the real world. They frequently used superhero words and images in describing their fight for better health. Physicians can use these insights when counseling SJIA patients to provide a narrative that meshes with the patients’ worldview and perhaps to improve physician–patient communication to increase treatment adherence.

Abstract
Objective The objective of this study was to determine the risk of obesity and metabolic syndrome in adults with a history of juvenile arthritis (JA). Methods Using the National Health and Nutrition Examination Survey (NHANES), we compared the characteristics of respondents with arthritis (JA vs rheumatoid arthritis [RA]) to those of the control group without arthritis. We used logistic regression analyses, controlling for age, race, and gender, to determine the ORs for metabolic syndrome. Results Obesity was increased in the JA group with 67% respondents having body mass index ≥30 kg/m2 vs 55% respondents in the no arthritis cohort (p=0.004). In unadjusted analyses, there was increased odds of metabolic syndrome in JA (OR 6.2, p=0.001) and RA groups compared to those without arthritis (OR 7.7, p=0.001). After adjusting for age, gender, and race, the odds of metabolic syndrome remained increased in JA (OR 5.2, p=0.001) and RA (OR 3.2, p=0.001) groups. Conclusion Adults with a history of JA have a significantly increased risk of metabolic syndrome compared to those without arthritis. These findings are important because metabolic syndrome has been associated with an increased risk of cardiovascular disease and death in other populations.

Abstract
Background There is growing evidence that supporting self-management of Juvenile Arthritis can benefit both patients and professionals. Young people with Juvenile Arthritis and their healthy peers increasingly use mobile technologies to access information and support in day-to-day life. Therefore, a user-led, rigorously developed and evaluated mobile app could be valuable for facilitating young people’s self-management of Juvenile Arthritis. Objective The objective of this study was to seek the views of young people with Juvenile Arthritis, their parents or carers, and health care professionals (HCPs) as to what should be included in a mobile app to facilitate young people’s self-management of chronic Juvenile Arthritis. Methods A qualitative approach was adopted with a purposeful sample of 9 young people aged 10-18 years with Juvenile Arthritis, 8 parents or carers, and 8 HCPs involved in their care. Data were gathered through semi-structured focus group and individual interviews with young people and their parents or carers and HCPs. Interview discussion was facilitated through demonstration of four existing health apps to explore participants’ views on strengths and limitations of these, barriers and facilitators to mobile app use, preferred designs, functionality, levels of interaction, and data sharing arrangements. Data were analyzed using the framework approach. Results Analysis revealed three interlinked, overarching themes: (1) purpose, (2) components and content, and (3) social support. Despite some differences in emphasis on essential content, general agreement was found between young people with Juvenile Arthritis their parents or carers, and professionals that a mobile app to aid self-management would be useful. Underpinning the themes was a prerequisite that young people are enabled to feel a sense of ownership and control of the app, and that it be an interactive, engaging resource that offers developmentally appropriate information and reminders, as well as enabling them to monitor their symptoms and access social support. Conclusions Findings justify and pave the way for a future feasibility study into the production and preliminary testing of such an app. This would consider issues such as compatibility with existing technologies, costs, age, and cross-gender appeal as well as resource implications.

Abstract
Gut microflora and dysbiosis as an environmental factor has been linked to the pathogenesis of enthesitis-related arthritis (JIA-ERA); thus, we performed a proof-of-concept study of probiotics to modulate the gut-flora and study the effects on immune and clinical parameters of children having JIA-ERA. Forty-six children with active JIA-ERA were randomized to placebo or probiotic therapy along with non-steroidal anti-inflammatory drugs (NSAIDs) for 12 weeks. Patients were assessed using a six-point composite disease activity index (mJSpADA) based on morning stiffness, joint count, enthesitis count, sacroiliitis/inflammatory back pain, uveitis and erythrocyte sedimentation rate/C-reactive protein (ESR/CRP). Frequencies of T helper type 1 (Th1), Th2, Th17 and regulatory T cells in blood were measured using flow cytometry. Serum cytokines interferon (IFN)-γ, interleukin (IL)-4, IL-17, IL-10, tumour necrosis factor (TNF)-α and IL-6 were measured by cytokine bead array using flow cytometer. The average age of 46 children (44 boys) was 15 ± 2.5 years and duration of disease was 3.5 ± 3 years. There was no significant difference in improvement in mJSpADA between the two groups (P = 0·16). Serum IL-6 levels showed a decrease (P < 0·05) in the probiotic-group. Th2 cell frequency (P < 0·05) and serum IL-10 levels (P < 0·01) showed an increase in the placebo group, but again the probiotic use did not show a significant change in immune parameters when compared to the placebo. Adverse effects among the probiotic and placebo groups were diarrhea (36 versus 45%), abdominal pain (9 versus 20%), minor infections (4·5 versus 20%) and flatulence (23 versus 15%), respectively. Thus, we can conclude that probiotic therapy in JIA-ERA children is well tolerated, but failed to show any significant immune or clinical effects over NSAID therapy.

Abstract
BACKGROUND Few series report the results of total elbow replacement (TER) in patients with juvenile idiopathic arthritis (JIA). Most report the use of a linked implant. There are theoretical benefits to using an unlinked prosthesis, and thus we report our experience of the clinical benefit and survivorship of both this implant and a linked semiconstrained prosthesis. METHODS There were 21 elbows replaced in 14 JIA patients (12 women and 2 men; 14 unlinked, 7 linked). Mean age at surgery was 39.5 years (range, 26-52 years). Mean clinical follow-up was 11.7 years (range, 5.4-17.6 years). RESULTS Reoperation, including implant revision, was required in 9 elbows (42.9%). Using revision as an end point, survivorship was 95% (95% confidence interval [CI], 74%-99%) at 5 years and 68% (95% CI, 45%-86%) at 10 years. The 10-year survival was 70% (95% CI, 40%-89%) for the unlinked group and 69% (95% CI, 28%-94%) for the linked group. The need for bilateral TER was found to be a risk factor for revision within 10 years of primary surgery (6/11 vs. 0/7 elbows; P = .037). The rate of aseptic loosening seen on radiographs was high in the unlinked group (12/14, 85.7%), but many of these patients continue to function well without need for revision. CONCLUSION Both the unlinked Kudo 5 and linked Coonrad-Morrey prostheses for TER can provide benefits in the long-term for most patients with JIA. The need for bilateral TER in this group is associated with higher rate of revision at 10 years.

Abstract
In Asia, enthesitis-related arthritis (ERA) is the most frequent category of juvenile idiopathic arthritis. ERA has a strong association with human leucocyte antigen (HLA)-B27 and subclinical gut inflammation. In an HLA-B27 transgenic rat model, the presence of Bacteroides bacteria in the gut appears to cause spondyloarthropathy (SpA). Thus, we studied gut microbiota in children with ERA. Stool specimens from 33 patients with ERA and 14 age-matched healthy controls were studied; none had any gastrointestinal symptom, or had received a drug known to affect gut motility or microbiota in the preceding 6 weeks. From each specimen, a cDNA library for the V3 region of bacterial 16S rRNA was subjected to high-throughput, massively parallel sequencing. Relationship of the specimens was studied using principal co-ordinate analysis (PCoA), and abundances of various bacterial taxa and alpha diversity were compared between groups. In eight patients, a repeat faecal specimen was studied after 12 weeks of probiotic therapy. The 55 specimens yielded a median (range) of 397 315 (102 093-1 502 380) high-quality reads each. In PCoA, gut microbiota from ERA showed a wider dispersion than those from controls. In patients, families Bacteroidaceae and Enterobacteriaceae were more abundant and Prevotellaceae were less abundant than in controls. Also, genera Bacteroides, Entercoccus and Klebsiella were over-represented and genus Prevotella was under-represented in ERA patients. Probiotic therapy led to a non-significant increase in Prevotellaceae. Patients with ERA have a dysbiosis in the gut, with increased abundance of Bacteroides and reduction of Prevotella. Probiotic supplementation in a subset of patients did not reverse these changes significantly.

Abstract
Microarray of peripheral blood (PB) and synovial fluid mononuclear cells (PBMC, SFMC) of patients with juvenile idiopathic arthritis-enthesitis-related arthritis (JIA-ERA) has shown the involvement of monocytes. On the basis of CD14 and CD16 expression, monocytes are classified as classical, intermediate and non-classical. In response to Toll-like receptor (TLR) stimulation, intermediate monocytes produce proinflammatory cytokines and play a role in inflammatory diseases. Therefore, we have studied the microarray profile of monocytes, the frequency of their subsets and cytokine production. Monocyte-specific microarray analysis was performed in six healthy controls' PBMC and six patients' PBMC and SFMC using Illumina chips WG12. Monocyte subsets were assessed in 46 patients with JIA-ERA and 17 healthy controls and 17 disease controls by flow cytometry. Interleukin (IL)-23 and tumour necrosis factor (TNF) levels were measured in culture supernatants of eight controls and seven patients' PBMC/SFMC with/without lipopolysaccharide (LPS) stimulation. Cytokine-producing intermediate monocytes were assessed by flow cytometry. Genes related to antigen presentation, cytokine signalling and TLR pathway were regulated differentially in PB and synovial monocytes of patients with JIA-ERA. Key genes of intermediate monocytes, such as CLEC10A and MARCO, were expressed three- to fourfold more in JIA-ERA. In PB, the frequency of intermediate monocytes was significantly higher in JIA-ERA (4·90% ± 3·5) compared to controls (1·8% ± 1·06; P < 0·001). Patients' synovial cells also had more intermediate monocytes compared to PB (11·25% ± 11·32, 5·9% ± 4·8; P = 0.004). Intermediate monocytes are the major producers of IL-23. Thus, intermediate monocytes may play an important role in JIA-ERA, possibly by producing cytokines, and contribute to joint inflammation.

Abstract
The clinical presentation, disease associations, and diverse treatment modalities in overcoming the challenges of managing pediatric psoriasis have been extensively summarized in this article. An extensive literature review revealed the differences in presentation of psoriasis during infancy, childhood, and adolescence. We also summarized the latest topical, systemic, and biological modalities in treating recalcitrant psoriasis. The association of psoriasis with juvenile arthritis and obesity and the significant influence of the disease on the children's quality of life were explored. The clinical presentation of psoriasis can evolve during the child's lifespan. While many treatment modalities already exist for treating pediatric psoriasis, some of the new biologics that are approved for adult patients have not been investigated in the pediatric population and no algorithm exists for their use in this population. Large clinical studies in the future will enhance our understanding with regards to their safety and potential implications in pediatric populations.

Abstract
BACKGROUND Despite the wealth of clinical research carried out in children with juvenile idiopathic arthritis (JIA), little is known about the emotional experiences of their parents. This article describes the predominant emotional experiences reported by parents of children with JIA in two Canadian cities. METHODS Research participants included 15 experienced parents and 8 novice parents (<6 months since children's JIA diagnosis). Their children were 2 to 16 years old with various JIA categories. A qualitative dataset including audio recordings and verbatim transcripts of three focus groups, and written reports of 59 reciprocal interviews (parents interviewing each other) were examined by a multidisciplinary research team following a four-step qualitative analytical process. RESULTS Parents of children with JIA experienced recurrent mixed negative and positive emotions that varied over time. Between disease onset and diagnosis, mounting anxiety, fear and confusion were the predominant emotions. Shortly after diagnosis there were shock, disbelief, and fear, with a sense of having being blindsided by the disease. At times of disease quiescence there was hope and gratitude, but also fatigue and frustration with ongoing treatment and fear of flares. During periods of increasing or ongoing symptoms there was admiration and sympathy for the courageous way children coped with JIA, as well as sorrow and frustration for ongoing pain and limitations. There were at times, frustration and indignation with peers and teachers unable to understand the child's fluctuations in physical activity and schoolwork. Throughout the disease, parents felt an underlying anxiety and powerlessness. CONCLUSIONS Parents of children with JIA described complex emotional journeys akin to the recurring ups and downs of rollercoaster rides, instead of ordered emotional phases ending in resolution. This has implications for healthcare providers who need to be aware of the complexity of these emotional journeys to support parents more effectively, thereby helping improve patient outcomes.

Abstract
Background Shareable online video offers the potential for spreading a health message across online and real world social networks. Seeding a message in a clinical setting may be advantageous. Objective To investigate the potential of an online video to spread a health message about juvenile idiopathic arthritis (JIA) when delivered or seeded in a clinical setting and investigate factors that influence sharing behavior. Methods Multimethod proof of concept study. Concepts for two different styles of video were developed using focus groups and interviews and reviewed by an online market research panel. We compared dissemination of the two videos from two specialist pediatric rheumatology clinics in NHS Hospitals. Participants were 15 patients, family members, and clinical staff with knowledge of JIA at concept stage; 300 market research panel members in development stage; and 38 patients and their parents or guardians in the seeding stage. Newly diagnosed patients with JIA and/or parents or guardians were invited to view and share an online video with a health message about JIA across real-life and electronic social networks. Main outcome measures were viewing statistics, sharing behavior and patterns, and participant feedback. Results Of 38 patients and/or their parents or guardians given links, 26 visited the video webpage and shared the link, 2 visited and did not share, and 10 did not visit. Most links were viewed and shared within a few days. A total of 3314 pageviews were recorded with a mean of 89.6 pageviews per link (range 0-1245). Links were accessed from 26 countries, with most viewers in the United Kingdom (82.5%). Mothers were the most active group of sharers. Conclusions Distribution of a video link in a clinical setting may be an effective way to spread a health message. Parents or guardians of children with JIA are more likely to share a link than young people. Dissemination depends on a small number of active sharers, the content of the video, and the willingness of participants to share health information about themselves.

Abstract
BACKGROUND Temporomandibular joint (TMJ) inflammation in patients with juvenile idiopathic arthritis (JIA) can lead to orofacial pain and malfunction of the TMJ. Intra-articular corticosteroid injections (IACI) have been suggested as a treatment modality against TMJ arthritis-related orofacial signs and symptoms. However, knowledge of the effect-durability of these injections remains unanswered. The aim of this pilot study was to evaluate the short and long-term effects of IACI on orofacial symptoms in a prospective observational study based on pre-specified clinical examination standards. METHODS Thirteen patients with JIA and arthritis-related orofacial signs and symptoms were included in this prospective pilot study (median 17.2 years, IQR 15-18.4 years). All patients received TMJ IACI (11 bilateral and two unilateral) due to an insufficient response to previous pain-management treatments. Three standardized clinical examinations were carried out: T1 prior to treatment, T2 short-term follow-up (mean 34 days post-treatment), T3 long-term follow-up (mean 333 days post-treatment). RESULTS Significant pain reduction was observed at the short-term follow-up (T2). Resolution of orofacial pain after IACI was a rare finding at T2. Generally, the pain significantly worsened between T2 and T3 examinations. The reported pain levels rose between T2 and T3 indicating a loss of effect of the IACI at the long-term follow-up examination (T3). Non-significant improvements in TMJ mobility were observed at T2 and T3. CONCLUSION Our results suggest a palliative (not curative) effect of IACI for TMJ arthritis-related orofacial symptoms in patients with long-term orofacial pain complaints. The short-term improvements in signs and symptoms were partly resolved at the long-term follow-up.

Abstract
Variations affecting the growth centers can severely affect the normal formation and subsequent function of vital musculoskeletal structures. We report a case of bilateral condylar atrophy with a history of juvenile arthritis (JA) resulting in progressive obstructive sleep apnea (OSA) in adulthood. In addition to this, the case report emphasizes the role of temporomandibular joint replacement and advancement of the mandible to correct progressive OSA secondary to idiopathic JA. Computed tomography revealed micrognathia, condylar hypoplasia, and decreased pharyngeal airway space. The resultant increase in the retrolingual-pharyngeal airway space following the surgery, helped to completely resolve the presenting symptoms. It is hoped that the described technique could be used in similar cases with a predictable outcome.

Abstract
BACKGROUND Earlier studies have shown that delivery by cesarean section (CS) is associated with an increased risk of disease associated with immune function in the offspring, but these studies have generally not discriminated between the effect of acute and elective CS. OBJECTIVE We sought to further explore these associations using discrimination between the effects of acute versus elective CS. METHODS We performed a population- and national register-based cohort study including all children born in Denmark from January 1997 through December 2012. Hazard ratios for diseases associated with immune function in children delivered by acute and elective CS with vaginal delivery as the reference were calculated by using Cox regression. All analyses were adjusted for gestational age, sex, birth weight, maternal age, maternal smoking during pregnancy, and complications during pregnancy (preeclampsia, eclampsia, hemorrhage, and hyperemesis). RESULTS A total of 750,569 children aged 0 to 14 years were included. Children delivered by both acute and elective CS had an increased risk of asthma, laryngitis, and gastroenteritis. Children delivered by acute CS had an increased risk of ulcerative colitis and celiac disease, whereas children delivered by elective CS had an increased risk of lower respiratory tract infection and juvenile idiopathic arthritis. The effect of elective CS was higher than the effect of acute CS on the risk of asthma. CONCLUSION Children delivered by CS are at increased risk of disease associated with immune function. The effect is mainly on diseases involving the mucosal immune system.

Abstract
PURPOSE To determine whether patients with juvenile systemic granulomatous disease (JSGD) (Blau syndrome) and uveitis have a characteristic ocular phenotype. METHODS Clinical and imaging data were collected retrospectively from patients attending the Regional Combined Paediatric Rheumatology and Ocular Inflammatory Service, Bristol Eye Hospital. General demographic information, laterality of the uveitis, age at onset, anatomical classification and course of the uveitis, clinical phenotype and specific NOD2 mutation were recorded for each patient. RESULTS Seventeen eyes from nine patients (five males; four females) were included in the study. Mean age at the disease onset was 15 months, range 1-84 months. Eight patients had bilateral uveitis. Anterior uveitis was present in five eyes, intermediate uveitis in two eyes, and there were 10 eyes with panuveitis, manifesting as multifocal choroiditis. Appearance of optic disc included indistinct disc margins in six eyes, optic nerve head pallor in six eyes, optic disc vessel sheathing in four eyes, and there was peripapillary hypo/hyperpigmentation in 13 eyes accompanied with characteristic peripapillary nodular excrescences. Among NOD2 mutations, the p.R334W was the most commonly detected (n: four cases), and three patients carried novel variants, the p.E338D and p.D390V variants in one patient, and the p.H520Y and p.Q809K variants in two different patients. CONCLUSIONS Chronic bilateral panuveitis and a nodular peripapillary appearance in childhood onset uveitis are characteristic features of JSGD, which support the need for an appropriate genetic NOD2 analysis.

Abstract
Aim was to evaluate effect of unilateral distraction osteogenesis (DO) on mandibular morphology in rabbits with antigen-induced arthritis in the temporomandibular joint (TMJ). Forty 8-week-old rabbits were divided into four groups. In groups A,C, arthritis was induced in the right TMJ. Groups A,B underwent DO. Group D served as control group. Cephalometric analysis of mandibular angle, mandibular ramus height, mandibular collum height, and total posterior mandibular height was done on CT-scans preoperatively (T0), after distraction (T1), and at euthanasia (T2). Two-factor ANOVA evaluated the effect of DO and antigen-induced arthritis. No effect of DO or arthritis was observed on mandibular angle or mandibular collum height. For T0-T1, DO increased mandibular ramus height 12.3% (95% CI 5.2-19.4%) in group B (P=0.001) and total posterior mandibular height 6.2% (95% CI 0.3-12.1%) in group A (P=0.04) and 10.0% (95% CI 4.3-15.7%) in group B (P=0.001). For T1-T2, no significant changes occurred in arthritic rabbits (group A). In conclusion, DO increased total posterior mandibular height in rabbits with arthritis. Postoperatively, no significant effect of DO was observed in rabbits with arthritis. Mandibular DO could be a viable treatment modality in patients with TMJ-arthritis.

Abstract
Juvenile idiopathic arthritis (JIA) is a group of disorders characterized by arthritis persisting for at least 6 weeks with onset before the age of 16 years. Within this cluster of conditions, the polyarticular form (involving more than four joints within the first 6 months) is further divided based on the presence of rheumatoid factor. Children with polyarticular JIA pose unique diagnostic and therapeutic challenges compared to children with involvement of fewer joints. Polyarticular JIA patients tend to have a more refractory course and therefore are at increased risk for joint damage, resulting in poorer functional outcomes and decreased quality of life. Although the ability to treat this disorder continues to improve, especially with the advent of biologic agents, there is still much about the epidemiology and pathogenesis of polyarticular JIA that is unknown. The epidemiology of polyarticular JIA varies worldwide with a vast difference in reported cases between different global regions as well as within individual countries. Several genetic risk loci have been identified conferring increased susceptibility to JIA, many within the human leukocyte antigen region. Beyond the genome, environmental factors also seem to contribute to the etiology of polyarticular JIA. This review article will focus on the epidemiology and current treatments of polyarticular JIA and briefly discuss genetic and environmental influences on the pathogenesis of JIA as well as new and emerging therapies.

Abstract
OBJECTIVE The aim of this study was to investigate the current use of musculoskeletal US (MSUS) and the most relevant areas of interest for this imaging modality in paediatric rheumatology. METHODS A questionnaire was developed by the paediatric subgroup of the OMERACT US task force and e-mailed to the members of the main international paediatric rheumatology networks and societies. Responses were entered in an electronic database. Results were analysed quantitatively or summarized qualitatively in the case of open questions. RESULTS The overall response rate was 36% (262/719). The use of MSUS varied among members of the various networks/societies. MSUS was considered of high relevance for improvement of diagnostic skills, for the guidance of joint injections and for the assessment of specific joints, namely the hip, ankle, midfoot and wrist. It was considered useful for early detection of synovitis and in determining disease activity and disease remission. CONCLUSION Although at present MSUS is not widely used by paediatric rheumatologists, there is considerable interest in this imaging technology among members of the international networks. The results of this survey suggest that the next objective in the research agenda should be the standardization of the assessment of joints in healthy children. This will then help differentiate pathological (i.e. synovitic) joints from normal joints. The initial target joints should be the hip, ankle, midfoot and wrist. MSUS training focused on the assessment of paediatric patients might be very important in implementing the use of this technique in clinical practice and research.
