Development of clinical diagnostic criteria for plaque psoriasis in children: An eDelphi consensus study with the International Psoriasis Council.

Br J Dermatol 2019 Apr 10. Epub 2019 Apr 10.

Centre of Evidence Based Dermatology, University of Nottingham, Nottingham, UK.

Psoriasis in children can be a challenging diagnosis: the clinical presentation is often more subtle, may occur in covered sites and can be an unexpected diagnosis as psoriasis if often thought to occur at older ages. Poor recognition and delayed diagnosis of psoriasis in children can lead to inadequate treatment and lack of monitoring for comorbidities including juvenile psoriatic arthritis. Diagnostic criteria would help both clinical practice and clinical research, but to date none are available. Read More

Measurement properties and performance of an eight-minute submaximal treadmill test in patients with juvenile idiopathic arthritis: a controlled study.

Pediatr Rheumatol Online J 2019 Apr 8;17(1):14. Epub 2019 Apr 8.

Department of Rheumatology, Oslo University Hospital, Rikshospitalet, Oslo, Norway.

Background: Poor cardiorespiratory fitness is previously reported in patients with juvenile idiopathic arthritis (JIA) measured both by maximal and submaximal exercise tests, but a submaximal exercise test with acceptable measurement properties is currently lacking for both clinical and research purposes in this patient population. The objectives of this study were to evaluate the measurement properties and performance of a submaximal treadmill test in patients with JIA, and to compare the results with those obtained in controls.

Methods: Fifty-nine patients (50 girls), aged 10-16 years, with oligo- (n = 30) and polyarticular (n = 29) JIA, and 59 age- and sex-matched controls performed an eight-minute submaximal treadmill test for estimating peak oxygen uptake (VO) followed by a maximal treadmill test measuring VO directly.

Tofacitinib Treatment of Refractory Systemic Juvenile Idiopathic Arthritis.

Pediatrics 2019 Apr 4. Epub 2019 Apr 4.

Department of Rheumatology and Immunology, Guangdong Second Provincial General Hospital, Guangzhou, China; and

Systemic juvenile idiopathic arthritis (sJIA) is an aggressive form of childhood arthritis accompanied by persistent systemic inflammation. Patients with sJIA often exhibit poor response to conventional disease-modifying antirheumatic drugs, and chronic glucocorticoid use is associated with significant adverse effects. Although biologics used to target interleukin 1 and interleukin 6 are efficacious, the long-term commitment to frequent injections or infusions remains a challenge in young children. Read More

Causes of Revision in Young Patients Undergoing Total Hip Arthroplasty.

J Arthroplasty 2019 Mar 12. Epub 2019 Mar 12.

Adult Reconstruction and Joint Replacement Service, Hospital for Special Surgery, New York, NY.

Background: The purpose of this study was to identify reasons for revision of total hip arthroplasty (THA) in patients who underwent primary THA at or before the age of 35 years. We hypothesized that the reasons for revision in younger patients would be different from the general older population of patients undergoing THA because of the differences in diagnoses, complexity of deformities, and differences in activity level.

Methods: Data for 108 hips in 82 patients who underwent primary THA at our institution before the age of 35 years from 1982-2007 and subsequently underwent revision THA were reviewed. Read More

Th17 and Th1 Lymphocytes in Oligoarticular Juvenile Idiopathic Arthritis.

Front Immunol 2019 14;10:450. Epub 2019 Mar 14.

Department of Experimental and Clinical Medicine and DENOTHE Center, University of Florence, Florence, Italy.

In the last years much attention has focused on the Th17 and Th1 phenotypes and on their pathogenic role in juvenile idiopathic arthritis, investigating how the cytokines produced by T helper cells act on resident cells on the synovia and which signal transduction pathways regulate Th17 cells proliferation and plasticity. In this context, an important milestone was represented by the identification of the non-classic Th1 phenotype, developed from the shift of Th17 cells. The cytokine TNF-α, beyond its well-known proinflammatory activity is involved in this process and this is one of the reasons why the TNF-α inhibitors are widely used in the treatment of juvenile idiopathic arthritis patients.

Risk of juvenile idiopathic arthritis among children conceived after fertility treatment: a nationwide registry-based cohort study.

Hum Reprod 2019 Mar 30. Epub 2019 Mar 30.

Virus, Lifestyle and Genes, Danish Cancer Society Research Center, Copenhagen, Denmark.

Study Question: Is the risk of juvenile idiopathic arthritis (JIA) increased in children conceived after fertility treatment, and is an observed association caused by specific types of fertility treatment or by factors associated with the underlying infertility?

Summary Answer: The risk of JIA in children conceived after fertility treatment (any and specific types of fertility treatment) was not convincingly affected when compared with children born to fertile women.

What Is Known Already: It has been suggested that fertility treatment may affect the development of the immune system and thereby increase the risk of developing autoimmune diseases, including JIA.

Study Design, Size, Duration: This retrospective population-based cohort study included all live-born children in Denmark between 1 January 1996 and 31 December 2012 (n = 1 084 184). Read More

CCL21/CCR7 axis regulating juvenile cartilage repair can enhance cartilage healing in adults.

Sci Rep 2019 Mar 26;9(1):5165. Epub 2019 Mar 26.

Department of Orthopaedic Surgery, Faculty of Medicine and Graduate School of Medicine, Hokkaido University, Sapporo, Japan.

Juvenile tissue healing is capable of extensive scarless healing that is distinct from the scar-forming process of the adult healing response. Although many growth factors can be found in the juvenile healing process, the molecular mechanisms of juvenile tissue healing are poorly understood. Here we show that juvenile mice deficient in the chemokine receptor CCR7 exhibit diminished large-scale healing potential, whereas CCR7-depleted adult mice undergo normal scar-forming healing similar to wild type mice.

Dynamics of concomitant therapy in children with juvenile idiopathic arthritis treated with etanercept and methotrexate.

Pediatr Neonatol 2019 Feb 22. Epub 2019 Feb 22.

Biostatistics and Clinical Trials Center, Novosibirsk, Russia.

Background: Both the steroid- and NSAID-sparing effects of biologics in juvenile idiopathic arthritis (JIA) treatment are key aspects of the dynamics of patient's condition. The proper selection of biologics enables maximum treatment effectiveness and reduction of the dosage of concomitant therapy. Our aim was to study the dynamics of concomitant therapy during etanercept (ETA) and methotrexate (MTX) treatment in patients with JIA. Read More

An Algorithm for Management of Dentofacial Deformity Resulting From Juvenile Idiopathic Arthritis: Results of a Multinational Consensus Conference.

J Oral Maxillofac Surg 2019 Feb 21. Epub 2019 Feb 21.

Associate Professor, Division of Oral and Maxillofacial Surgery, Department of Surgery, Emory University School of Medicine; and Associate Chief, Oral and Maxillofacial Surgery, Children's Healthcare of Atlanta, Atlanta, GA.

Purpose: Juvenile idiopathic arthritis (JIA) frequently affects the temporomandibular joints and may cause dentofacial deformity and dysfunction. The adverse effects of JIA on dentofacial growth, morphology, and function may be due to erosion of the existing mandibular condyle(s), the inhibitory effect of the arthritis on the growing mandible, or both. No algorithm exists for management of JIA-induced skeletal and dental abnormalities; treatment varies widely. Read More

Transcriptomic and proteomic analysis of iris tissue and aqueous humor in juvenile idiopathic arthritis-associated uveitis.

J Autoimmun 2019 Mar 15. Epub 2019 Mar 15.

Department of Ophthalmology and Ophtha-Lab at St. Franziskus-Hospital, Münster, Germany; Department of Ophthalmology, University of Duisburg-Essen, Essen, Germany.

Gene and protein expression profiles of iris biopsies, aqueous humor (AqH), and sera in patients with juvenile idiopathic arthritis-associated uveitis (JIAU) in comparison to control patients with primary open-angle glaucoma (POAG) and HLA-B27-positive acute anterior uveitis (AAU) were investigated. Via RNA Sequencing (RNA-Seq) and mass spectrometry-based protein expression analyses 136 genes and 56 proteins could be identified as being significantly differentially expressed (DE) between the JIAU and POAG group. Gene expression of different immunoglobulin (Ig) components as well as of the B cell-associated factors ID3, ID1, and EBF1 was significantly upregulated in the JIAU group as compared to POAG patients.

Plcγ2/Tmem178 dependent pathway in myeloid cells modulates the pathogenesis of cytokine storm syndrome.

J Autoimmun 2019 Mar 15. Epub 2019 Mar 15.

Department of Orthopaedic Surgery, Musculoskeletal Research Center, Washington University School of Medicine, St. Louis, MO, USA; Shriners Hospitals for Children, St. Louis, MO, USA. Electronic address:

Cytokine storm syndrome (CSS) is a life-threatening condition characterized by excessive activation of T cells and uncontrolled inflammation, mostly described in patients with familial hemophagocytic lymphohistiocytosis and certain systemic auto-inflammatory diseases, such as systemic juvenile idiopathic arthritis (sJIA). Defects in T cell cytotoxicity as a mechanism for uncontrolled inflammation following viral infections fail to represent the whole spectrum of CSS. Evidence implicates dysregulated innate immune responses, especially activation of monocytes and macrophages, in patients with CSS. Read More

Comparing Proxy, Adolescent and Adult Assessments of Functional Ability in Adolescents with Juvenile Idiopathic Arthritis.

Arthritis Care Res (Hoboken) 2019 Mar 15. Epub 2019 Mar 15.

NIHR Manchester Biomedical Research Centre, Central Manchester University Hospitals NHS Foundation Trust, Manchester Academic Health Science Centre, Manchester, UK.

Objective: In paediatric research, investigators rely on proxy reports of outcome, such as the proxy-completed Childhood Health Assessment Questionnaire (P-CHAQ), to assess function in JIA. As children mature, they may self-complete the adult Health Assessment Questionnaire (HAQ) or the un-validated adolescent-specific CHAQ (A-CHAQ). It is unclear how these measures compare and whether they are directly interchangeable. Read More

Imaging findings of mixed connective tissue disease in children and adolescents: a case series.

Jpn J Radiol 2019 Mar 14. Epub 2019 Mar 14.

Department of Rheumatology, The Hospital for Sick Children, Department of Medical Imaging, University of Toronto, Toronto, ON, Canada.

Mixed connective tissue disease (MCTD) is a rare disease in children and adolescents which overlaps features of juvenile idiopathic arthritis, polymyositis/dermatomyositis, systemic lupus erythematosus, and systemic sclerosis. We have provided an image-based approach for evaluation of MCTD in children and adolescents, outlying the most frequent imaging findings. This approach would aid imagers and clinicians to consider the diagnosis of this rare entity and be able to make an accurate list of differential diagnosis for complex rheumatologic diseases such as MCTD, thus facilitating the ultimate goal of early diagnosis and optimal management of affected children.

Can ultrasound-detected subclinical synovitis be an indicator of flare recurrence in juvenile idiopathic arthritis remission patients on tapered TNFi?

Clin Exp Rheumatol 2019 Mar 7. Epub 2019 Mar 7.

Department of Rheumatology and Joint and Bone Research Unit, Hospital Universitario Fundación Jiménez Díaz, Madrid, Spain.

Objectives: Subclinical synovitis is often detected by musculoskeletal ultrasound (MSUS) in juvenile idiopathic arthritis (JIA) patients in clinical remission. The main objective of this prospective, observational, longitudinal, multicentre study was to evaluate the predictive value of MSUS-detected subclinical synovitis in relation to flares at 12 months following TNFi tapering in a JIA population in stable clinical remission.

Methods: We included 56 JIA patients in stable remission undergoing TNFi therapy tapered at baseline and in some cases at 6 months. Read More

Biallelic loss-of-function LACC1/FAMIN Mutations Presenting as Rheumatoid Factor-Negative Polyarticular Juvenile Idiopathic Arthritis.

Sci Rep 2019 Mar 14;9(1):4579. Epub 2019 Mar 14.

Department of Immunology, Hospital Clínic-IDIBAPS, Barcelona, Spain.

Juvenile idiopathic arthritis (JIA) is a complex rheumatic disease with both autoimmune and autoinflammatory components. Recently, familial cases of systemic-onset JIA have been attributed to mutations in LACC1/FAMIN. We describe three affected siblings from a Moroccan consanguineous family with an early-onset chronic, symmetric and erosive arthritis previously diagnosed as rheumatoid factor (RF)-negative polyarticular JIA.

Association of PTPN22 1858C/T Polymorphism with Autoimmune Diseases: A Systematic Review and Bayesian Approach.

J Clin Med 2019 Mar 12;8(3). Epub 2019 Mar 12.

Department of Pediatrics, Yonsei University College of Medicine, Yonsei-ro 50, Seodaemun-gu, C.P.O. Box 8044, Seoul 03722, Korea.

The 1858T allele in the protein tyrosine phosphatase non-receptor type 22 (PTPN22) locus shows one of the strongest and most consistent genetic associations with autoimmune diseases. We synthesized all meta-analyses reporting a genetic association of the PTPN22 1858T C/T polymorphism with autoimmune diseases. This work examined their validity to discover false positive results under Bayesian methods. Read More

Serum Leucine-Rich 2-Glycoprotein as a Biomarker for Monitoring Disease Activity in Patients with Systemic Juvenile Idiopathic Arthritis.

J Immunol Res 2019 4;2019:3140204. Epub 2019 Feb 4.

Department of Pediatrics, School of Medicine, Institute of Medical, Pharmaceutical, and Health Sciences, Kanazawa University, Kanazawa, Japan.

To investigate whether serum leucine-rich 2-glycoprotein (LRG) levels are useful as a marker of disease activity in systemic juvenile idiopathic arthritis (s-JIA), we determined serum LRG levels in fifty-nine s-JIA patients, 15 with other subtypes of JIA, 7 with Kawasaki disease (KD), 7 with influenza A infection (flu), 7 with enterohemorrhagic (EHEC) infection, and 20 healthy controls (HC). Results were compared with the clinical features of s-JIA and serum cytokine levels including interleukin- (IL-) 6, IL-18, and soluble tumor necrosis factor receptors I and II. Serum LRG levels in active s-JIA were higher compared to those in other subtypes of JIA, EHEC, flu patients, and HC. Read More

Machine learning identifies an immunological pattern associated with multiple juvenile idiopathic arthritis subtypes.

Ann Rheum Dis 2019 May 12;78(5):617-628. Epub 2019 Mar 12.

VIB Center for Brain and Disease Research, Leuven, Belgium

Objectives: Juvenile idiopathic arthritis (JIA) is the most common class of childhood rheumatic diseases, with distinct disease subsets that may have diverging pathophysiological origins. Both adaptive and innate immune processes have been proposed as primary drivers, which may account for the observed clinical heterogeneity, but few high-depth studies have been performed.

Methods: Here we profiled the adaptive immune system of 85 patients with JIA and 43 age-matched controls with indepth flow cytometry and machine learning approaches. Read More
