Abstract
Systemic juvenile idiopathic arthritis (SJIA) is a rare disease with distinct features not seen in other categories of juvenile idiopathic arthritis. In recent years, advances in the understanding of disease immunopathogenesis have led to improved targeted therapies with significant improvement in patient outcomes. Despite these advances, there remain subsets of SJIA with refractory disease and severe disease-associated complications. This review highlights existing options for treatment of refractory SJIA and explores potential future therapeutics for refractory disease.Key Points:Despite targeted Interleukin IL-1 and IL-6 inhibitors a subset of SJIA remains refractory to therapy. About 1 in 7 SJIA patients will be refractory to targeted IL-1 or IL-6 therapy.There is no current agreed upon definition for refractory SJIA and we propose in this review that refractory SJIA is presence of active systemic or arthritic features despite treatment with anti-IL-1 or anti-IL-6 therapy or disease requiring glucocorticoids for control beyond 6 months.SJIA disease associated complications include presence of associated macrophage activation syndrome (MAS), interstitial lung disease (ILD) or amyloidosis and management of each differs.Refractory SJIA treatment options currently include additional conventional synthetic disease modifying anti-rheumatic drugs (csDMARDS), biologic (bDMARDS), combination biologic therapy, targeted synthetic (tsDMARDS) or other immunomodulatory therapies.

Abstract
The molecular mechanisms of cytokine storm in patients with severe COVID-19 infections are poorly understood. To uncover these events, we performed transcriptome analyses of lung biopsies from patients with COVID-19, revealing a gene enrichment pattern similar to that of PPARγ-knockout macrophages. Single-cell gene expression analysis of bronchoalveolar lavage fluids revealed a characteristic trajectory of PPARγ-related disturbance in the CD14+/CD16+ cells. We identified a correlation with the disease severity and the reduced expression of several members of the PPARγ complex such as EP300, RXRA, RARA, SUMO1, NR3C1, and CCDC88A. ChIP-seq analyses confirmed repression of the PPARγ-RXRA-NR3C1 cistrome in COVID-19 lung samples. Further analysis of protein-protein networks highlighted an interaction between the PPARγ-associated protein SUMO1 and a nucleoprotein of the SARS virus. Overall, these results demonstrate for the first time the involvement of the PPARγ complex in severe COVID-19 lung disease and suggest strongly its role in the major monocyte/macrophage-mediated inflammatory storm.

Abstract
OBJECTIVE The incidence of inflammatory bowel disease (IBD) in juvenile idiopathic arthritis (JIA) is higher than in the general pediatric population. However, reports of IBD in the systemic JIA (sJIA) subtype are limited. We sought to characterize sJIA patients diagnosed with IBD and to identify potential contributing risk factors. METHODS Using an internationally distributed survey, we identified 16 patients with sJIA who were subsequently diagnosed with IBD (sJIA-IBD cohort). Five hundred twenty-two sJIA patients without IBD were identified from the CARRA Legacy Registry and served as the sJIA-only cohort for comparison. Differences in demographic, clinical characteristics, and therapy were assessed using chi-square test, Fisher exact test, t-test, and univariate and multivariate logistic regression, as appropriate. RESULTS Of the patients with sJIA-IBD, 75% had a persistent sJIA course and 25% had a history of macrophage activation syndrome. sJIA-IBD subjects were older at sJIA diagnosis, more often non-White, had a higher rate of IBD family history, and were more frequently treated with etanercept or canakinumab compared to sJIA-only subjects. Sixty-nine percent of sJIA-IBD patients successfully discontinued sJIA medications following IBD diagnosis, and sJIA symptoms resolved in 9 of 12 patients treated with tumor necrosis factor-α (TNF-α) inhibitors. CONCLUSION IBD in the setting of sJIA is a rare occurrence. The favorable response of sJIA symptoms to therapeutic TNF-α inhibition suggests that the sJIA-IBD cohort may represent a mechanistically distinct sJIA subgroup. Our study highlights the importance of maintaining a high level of suspicion for IBD when gastrointestinal involvement occurs in patients with sJIA and the likely broad benefit of TNF-α inhibition in those cases.

World J Pediatr 2020; 16:68-73. [PMID: 31612428 DOI: 10.1007/s12519-019-00316-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2019] [Accepted: 09/16/2019] [Indexed: 01/19/2023]
Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease that includes seven heterogeneous subgroups with different prognoses. In particular, polyarticular JIA (pJIA) has a longer period of active disease and a poorer prognosis. Tumor necrosis factor (TNF)-alpha inhibitors are effective in patients with pJIA, but the therapeutic regimen remains controversial. Here, we performed a single-center study to determine the potential correlation between TNF-alpha inhibitor (infliximab) therapy and outcomes in these patients. METHODS Clinical data of 40 pJIA patients were collected at our center from January 1, 2010 to January 1, 2018, and patients were grouped according to the timing of infliximab therapy. The erythrocyte sedimentation rate (ESR), the number of joints with active disease, and the 27-point juvenile arthritis disease activity score (JADAS-27) were analyzed. RESULTS The ESR, the active joint count, and the JADAS-27 decreased significantly in all groups after 3 months (P = 0.041/0.415/0.008, 0.022/0.030/ < 0.001, and 0.05/0.012/ < 0.001, respectively) and 6 months (P = 0.036/0.045/0.041, 0.076/0.037/ < 0.001, and 0.096/0.006/ < 0.001, respectively) of infliximab treatment, although the rates of change of these parameters were similar. However, after 12 months, only patients treated with infliximab within 3 months of disease onset had a stable ESR, active joint count, and JADAS-27, while these parameters increased sharply when infliximab was administered 3 months and especially 1 year after disease onset. CONCLUSIONS TNF-alpha is a pleiotropic pro-inflammatory cytokine of crucial importance in the pathogenesis of JIA. Infliximab can improve the outcomes of patients with pJIA significantly, and should be introduced early during the clinical course.

Abstract
BACKGROUND Biologic therapy has changed the prognosis of patients with juvenile idiopathic arthritis (JIA). The aim of this study was to examine the pattern of use, drug survival, and adverse events of biologics in patients with JIA during the period from diagnosis to adulthood. METHODS All patients included in BIOBADASER (Spanish Registry for Adverse Events of Biological Therapy in Rheumatic Diseases), a multicenter prospective registry, diagnosed with JIA between 2000 and 2015 were analyzed. Proportions, means, and SDs were used to describe the population. Incidence rates and 95% CIs were calculated to assess adverse events. Kaplan-Meier analysis was used to compare the drug survival rates. RESULTS A total of 469 patients (46.1% women) were included. Their mean age at diagnosis was 9.4 ± 5.3 years. Their mean age at biologic treatment initiation was 23.9 ± 13.9 years. The pattern of use of biologics during their pediatric years showed a linear increase from 24% in 2000 to 65% in 2014. Biologic withdrawal for disease remission was higher in patients who initiated use biologics prior to 16 years of age than in those who were older (25.7% vs 7.9%, p < 0.0001). Serious adverse events had a total incidence rate of 41.4 (35.2-48.7) of 1000 patient-years. Patients younger than 16 years old showed significantly increased infections (p < 0.001). CONCLUSIONS Survival and suspension by remission of biologics were higher when these compounds were initiated in patients with JIA who had not yet reached 16 years of age. The incidence rate of serious adverse events in pediatric vs adult patients with JIA treated with biologics was similar; however, a significant increase of infection was observed in patients under 16 years old.

Abstract
Introduction Many children with juvenile idiopathic arthritis (JIA) continue to have active disease into adulthood. Adults with JIA are a heterogeneous group, and the effects of tumour necrosis factor inhibitor (TNFi) therapies are not well described. This analysis aims to describe treatment outcomes among patients with JIA starting TNFi for the first time in adulthood. Methods Patients with arthritis onset <16 years starting their first TNFi therapy were identified from the British Society of Rheumatology Biologics Register. Disease activity outcomes (using 28-joint Disease Activity Score (DAS28) and Health Assessment Questionnaire (HAQ)) are presented at 1 year after start of therapy according to disease pattern. Incidence rates (IR) of adverse events per 1000 person-years (pyrs) were calculated. Outcomes in patients with polyarticular JIA were compared with a cohort (weighted for age and gender) of patients with rheumatoid arthritis (RA). Results In 443 adults with JIA starting a first TNFi, disease activity over 1 year improved across all measures. There were 58 first serious infections (IR 22.3/1000 pyrs); 4 cardiovascular events (IR 1.4/1000 pyrs); 11 uveitis events (IR 4.0/1000 pyrs) and 16 malignancies (IR 3.9/1000 pyrs). Compared with the weighted RA cohort, disease activity improvement was similar; malignancy rates were lower and uveitis rates much higher. While crude IR were similar, JIA patients had a lower risk of serious infection (HR 0.5 (95% CI 0.3 to 0.9)). Conclusions This is the largest study to describe disease activity and safety outcomes in adults with JIA receiving TNFi. Disease activity improved after 1 year in all disease patterns, suggesting TNFi is an effective therapy in this population.

Abstract
OBJECTIVE Using administrative data from a large commercial US health insurer, we investigated temporal trends in medication use among children diagnosed with juvenile idiopathic arthritis (JIA). METHODS Children with ≥ 1 physician diagnosis code for JIA in the calendar years 2005 through 2012 were included. Use of tumor necrosis factor inhibitors (TNFi), methotrexate (MTX), nonsteroidal antiinflammatory drugs (NSAID), and oral glucocorticoids (GC) was determined. Temporal changes in medication usage were evaluated with the Cochran-Armitage test for trend. We used paired t-tests to evaluate the use of NSAID and GC in the 6 months before and after new TNFi use. RESULTS We identified 4261 unique individuals with JIA. The proportion of patients receiving TNFi increased from 8.7% in 2005 to 22.4% in 2012 (p < 0.0001). MTX use increased from 18.4% to 23.2% (p = 0.02). NSAID use decreased from 49% to 40% (p = 0.02). GC use was relatively unchanged. Following new TNFi use, the mean number of NSAID prescriptions (among prevalent users) decreased from 2.8 to 2.0 (p < 0.0001), and the mean daily GC dose (among prevalent users) decreased from 7.3 mg/day to 3.9 mg/day (p < 0.0001). Many new TNFi users (57%) had not used MTX in the previous 6 months, and only 37% had any concurrent MTX use in the 6 months following new TNFi use. CONCLUSION TNFi use in the treatment of JIA increased 2- to 3-fold over the last 8 years. New TNFi use was associated with decreased NSAID and GC use. TNFi may be replacing, rather than complementing, MTX in the treatment of many patients.

Abstract
Recent advances indicate that new therapeutic strategies for the treatment of malignancies will be realized from combined radiation treatment and immune checkpoint modulation. Numerous biophysical properties must be considered for effective biologic development, including affinity, selectivity, oligomeric state and valency. High-resolution structural characterization contributes to our understanding of these properties and can lead to the realization of proteins with unique in vitro activities and novel in vivo therapeutic functions. In this article we focus on the importance of these factors for new potential biologics and consider these in the context of combination therapies with physical modalities, including radiation therapy. In particular, we examine the consequences of altered avidities and subset-specific ligand density on the rational modification of biological function in the immunoglobulin and tumor necrosis factor superfamilies and for new optimized combination therapies.

Abstract
Tumour necrosis factor (TNF) plays an important role in the pathogenesis of immune-mediated inflammatory diseases (IMIDs). TNF inhibition results in down-regulation of abnormal and progressive inflammatory processes, resulting in rapid and sustained clinical remission, improved quality of life and prevention of target organ damage. Adalimumab is the first fully human monoclonal antibody directed against TNF. In this article, we review the role and cost effectiveness of adalimumab in the treatment of IMIDs in adults and children. The efficacy and tolerability of adalimumab has been demonstrated in patients with a wide range of inflammatory conditions, leading to regulatory approval in rheumatoid arthritis (RA), psoriatic arthritis (PsA), plaque psoriasis, inflammatory bowel diseases (Crohn's disease, ulcerative colitis, paediatric Crohn's disease, and intestinal Behçet's disease), ankylosing spondylitis (AS), axial spondyloarthritis (SpA) and juvenile idiopathic arthritis. The major tolerability issues with adalimumab are class effects, such as injection site reactions and increased risk of infection and lymphoma. As with all anti-TNF agents, adalimumab is immunogenic, although less than infliximab, and some patients receiving long-term adalimumab will develop anti-drug antibodies, causing a loss of response. Comparisons of its clinical utility and cost effectiveness have shown it to be a valid treatment choice in a wide range of patients. Recent data from Italian economic studies show the cost effectiveness of adalimumab to be below the threshold value for health care interventions for most indications. In addition, analysis of indirect costs shows that adalimumab significantly reduces social costs associated with RA, PsA, AS, Crohn's disease and psoriasis. The fact that adalimumab has the widest range of approved indications, many often presenting together in the same patient due to the common pathogenesis, may further improve the utility of adalimumab. Current clinical evidence shows adalimumab to be a valuable resource in the management of IMIDs. Further research, designed to identify patients who may benefit most from this drug, will better highlight the role and cost-effectiveness of this versatile TNF inhibitor.

Abstract
AIM To study real-life experiences of drug treatment discontinuations and safety in a well-defined cohort of patients with juvenile idiopathic arthritis (JIA), over an eleven-year period in Uppsala County, Sweden. METHODS Clinical charts of all incident and prevalent cases of juvenile arthritis were reviewed prospectively by an experienced paediatric rheumatologist. Each patient file was supplemented retrospectively regarding hereditary diseases, clinical data and aspects of pharmacological treatment. RESULTS Severe adverse events from methotrexate or biological agents were rare, but 84 occasions of interrupted therapy due to adverse events or inefficacy were identified within 225 treatment periods (37.3%) in the 156 patients (108 girls and 48 boys) studied. The median observation period was 8.6 years after disease onset (minimum 1.33, maximum 17.5 years). Oral and subcutaneous methotrexate caused adverse events in 22.6% of the treatment periods and biological agents in 19.2% (p = 0.71). Discontinuation of treatment periods was equally common for methotrexate (38.7%) and biological agents (33.3%) (p = 0.53). CONCLUSION Our study shows a high percentage of interrupted medical therapies, due to adverse events or inefficacy, in children with JIA. Adverse events from methotrexate and biological agents were seldom severe. The results highlight the need for better predictive factors to guide therapy.

Abstract
Macrophage activation syndrome (MAS) is an episode of overwhelming inflammation that occurs most commonly in children with systemic juvenile idiopathic arthritis (SJIA). It is characterized by expansion and activation of T lymphocytes and hemophagocytic macrophages and bears great similarity to hemophagocytic lymphohistiocytosis (HLH). This disorder has substantial morbidity and mortality, and there is frequently a delay in recognition and initiation of treatment. Here, we will review what is known about the pathogenesis of MAS and, in particular, its similarities to HLH. The development of MAS is characterized by a cytokine storm, with the elaboration of numerous pro-inflammatory cytokines. We will examine the evidence for various cytokines in the initiation and pathogenesis of MAS and discuss how new biologic therapies may alter the risk of MAS. Finally, we will review current treatment options for MAS and examine how cytokine-directed therapy could serve as novel treatment modalities.

Abstract
Juvenile idiopathic arthritis (JIA) is one of the most common chronic diseases of childhood. Although the pathophysiology behind this disease is poorly understood, there are effective treatments for JIA based on the subtype of disease. Treatment options include non-steroidal anti-inflammatory drugs, intra-articular glucocorticoid injections, and traditional disease modifying anti-rheumatic drugs such as methotrexate. In the past decade, the use of biologic therapy in JIA, including tumor necrosis factor inhibitors, interleukin-1 inhibitors, and interleukin-6 inhibitors, has dramatically increased with promising outcomes.

Abstract
Introduction The attainment of remission has become an important end point for clinical trials in juvenile idiopathic arthritis (JIA), although we do not yet have a full understanding of what remission is at the cell and molecular level. Methods Two independent cohorts of patients with JIA and healthy child controls were studied. RNA was prepared separately from peripheral blood mononuclear cells (PBMC) and granulocytes to identify differentially expressed genes using whole genome microarrays. Expression profiling results for selected genes were confirmed by quantitative, real-time polymerase chain reaction (RT-PCR). Results We found that remission in JIA induced by either methotrexate (MTX) or MTX plus a TNF inhibitor (etanercept, Et) (MTX + Et) is characterized by numerous differences in gene expression in peripheral blood mononuclear cells and in granulocytes compared with healthy control children; that is, remission is not a restoration of immunologic normalcy. Network analysis of the differentially expressed genes demonstrated that the steroid hormone receptor superfamily member hepatocyte nuclear factor 4 alpha (HNF4α) is a hub in several of the gene networks that distinguished children with arthritis from controls. Confocal microscopy revealed that HNF4a is present in both T lymphocytes and granulocytes, suggesting a previously unsuspected role for this transcription factor in regulating leukocyte function and therapeutic response in JIA. Conclusions These findings provide a framework from which to understand therapeutic response in JIA and, furthermore, may be used to develop strategies to increase the frequency with which remission is achieved in adult forms of rheumatoid arthritis.

Abstract
Objective.To review our experiences with high-dose infliximab (IFX) to treat juvenile idiopathic arthritis (JIA). We routinely use high doses of IFX (10–20 mg/kg) in children with recalcitrant or highly active JIA. Although biologics have revolutionized treatment of JIA, many patients have active disease despite therapy. Studies have shown benefits of high-dose IFX in several conditions, including inflammatory bowel disease, psoriasis, and idiopathic uveitis. The safety and effectiveness of high-dose IFX have not been evaluated in JIA.Methods.We performed a retrospective review of children with JIA who received IFX ≥ 10 mg/kg. We recorded all serious adverse events (SAE), medically important infections, and infusion reactions. We also recorded the physician global assessment of disease activity (MD global) and active joint count (AJC) at initiation of high-dose IFX and 3, 6, and 12 months thereafter.Results.Fifty-eight subjects received a total of 1064 infusions over 95 person-years. There were a total of 9 SAE (9.5/100 person-yrs), 7 of which were potentially related to therapy, and 6 infusion reactions (0.5%), none constituting anaphylaxis. Statistically significant improvements were observed in the AJC (median 0, range 0–31, vs 2, 0–39) and MD global (12, 2–31, vs 22, 5–80) over the first year.Conclusion.High-dose IFX appears safe in the management of JIA. Future prospective controlled studies are necessary to evaluate its safety and efficacy.

Abstract
BACKGROUND/PURPOSE The aim of the study was to describe the clinical features of children affected by juvenile idiopathic arthritis (JIA) under the International League of Associations for Rheumatology-derived classification criteria in a community-based setting. METHODS Consecutive cases of JIA from defined geographic areas of Taiwan were diagnosed and followed in an observational cohort from 1995 to 2010. In addition to the clinical and laboratory data required for the International League of Associations for Rheumatology system, information about the medication and disease activity during the study period was also recorded. RESULTS Out of 292 children with chronic joint pain, 195 were diagnosed as JIA: systemic arthritis (19%), oligoarthritis (persistent 16.4%; extended 6.7%), polyarthritis rheumatoid factor-negative (11.8%), polyarthritis rheumatoid factor-positive (4.6%), psoriatic arthritis (1.5%), enthesitis-related arthritis (ERA; 37.4%), and undifferentiated arthritis (2.6%). Human leukocyte antigen-B27 was positive in 82.2% of patients with ERA. Uveitis was observed in 6.7% of patients. Disease-modifying anti-rheumatic drugs, including biologic medications, were used in 73.3% of children during the observational period. At the last follow-up, 40% of patients experienced a continuously active or relapsing course. CONCLUSION Compared with previous reports on Western populations, a remarkably high prevalence was found in the ERA of the Chinese cohort, but a relatively low rate of uveitis. Ongoing disease activity was evident in a substantial number of children. These results provided a good starting point in understanding the epidemiology of this serious disease in the Chinese population.

Abstract
Treatment of children and adolescents with juvenile idiopathic arthritis and other pediatric rheumatic diseases has evolved. Where once there was only a limited arsenal of medications, with significant side effects and inadequate efficacy, today, with an increased understanding of the pathogenesis of these diseases, there is a wider variety of more targeted and effective treatments. TNF-α is a cytokine involved in a number of inflammatory pathways in pediatric rheumatic diseases. The emergence of biologic modifiers that target TNF-α has been pivotal in providing the ability to deliver early and aggressive treatment. Adalimumab, a recombinant monoclonal antibody to TNF-α, is an important therapeutic option, which affords children and adolescents with chronic illnesses an improved quality of life.

Abstract
Life-threatening disseminated tuberculosis developed in a 17-year-old girl who was treated with the TNF-α blocker adalimumab for refractory SAPHO syndrome. The patient presented to the emergency department with dyspnea and somnolence and within 2 h developed the clinical picture of a septic shock. In addition to this unusual presentation, she showed a complicated course with increasing cerebral granuloma formation in spite of adequate antimycobacterial treatment. Immune reconstitution after discontinuation of TNF blockade may contribute to this "paradoxical reaction." Possible implications for screening, diagnosis, and treatment of tuberculosis in children and adolescents receiving anti-TNF treatment are discussed.

Abstract
Tumour progression locus-2 (Tpl2) is a serine/threonine kinase, which regulates the expression of tumour necrosis factor α. The article describes the development of a robust pharmacophore model and the investigation of structure-activity relationship analysis of quinoline-3-carbonitrile derivatives reported for Tpl2 kinase inhibition. A five point pharmacophore model (ADRRR) was developed and used to derive a predictive atom-based 3-dimensional quantitative structure activity relationship (3D-QSAR) model. The obtained 3D-QSAR model has an excellent correlation coefficient value (r(2)= 0.96), Fisher ratio (F = 131.9) and exhibited good predictive power (q(2) = 0.79). The QSAR model suggests that the inclusion of hydrophobic substituents will enhance the Tpl2 kinase inhibition. In addition, H-bond donating groups, negative ionic groups and electron withdrawing groups positively contribute to the Tpl2 kinase inhibition. Further, pharmacophoric model was validated by the receiver operating characteristic curve analysis and was employed for virtual screening to identify six potential Tpl2 kinase inhibitors. The findings of this study provide a set of guidelines for designing compounds with better Tpl2 kinase inhibitory potency.

Abstract
Juvenile idiopathic arthritis (JIA) is the most common chronic inflammatory arthritic disease affecting children. Despite the availability of potent disease-modifying antirheumatic medications, most children still experience a chronic course with long periods of active disease. Goals of treatment should include achievement of disease remission with optimal physical functioning that allows children to lead normal lives with no structural joint damage. The term remission implies a complete lack of disease activity. This article focuses on recently developed preliminary criteria for inactive disease and remission in JIA. Recent studies using these new definitions demonstrate only modest rates of achievement of remission favoring children with persistent oligoarticular JIA. Children with rheumatoid factor-positive polyarticular JIA are least likely to achieve remission. Therapeutic strategies to achieve remission are also discussed.
