To investigate the clinical significance of soluble tumor necrosis factor receptor (sTNFR) II/I ratio as an indicator of the diagnosis of macrophage activation syndrome (MAS) complicating systemic juvenile idiopathic arthritis (s-JIA), we measured the serum sTNFRI and II levels in 117 patients with s-JIA, including 29 patients with MAS, 15 with Epstein-Barr virus-induced hemophagocytic lymphohistiocytosis (EBVHLH), 15 with Kawasaki disease (KD), and 28 healthy controls (HCs). We determined their correlation with measurements of disease activity and severity...

BACKGROUND: Flare-ups in juvenile idiopathic arthritis (JIA) are characterized by joint pain and swelling and often accompanied with fatigue, negative emotions, and reduced participation in activities. To minimize the impact of JIA on the physical and psychosocial development and well-being of young people (YP), it is essential to regularly monitor disease activity and side effects, as well as to support self-management such as adherence to treatment plans and engagement in general health-promoting behaviors...

OBJECTIVES: The temporomandibular joints (TMJs) are frequently affected in children with juvenile idiopathic arthritis (JIA). Early detection is challenging, as major variation is present in scoring TMJ pathology on Magnetic Resonance Imaging (MRI). Consensus-driven development and validation of a MRI scoring system for TMJs has important clinical utility in timely improvement of diagnosis, and serving as an outcome measure. We report on a multi-institutional collaboration towards developing a TMJ MRI scoring system for JIA...

Secondary thrombotic microangiopathies are associated with several underlying conditions, with most of them being resolved after the treatment of background disease. Thrombotic thrombocytopenic purpura (TTP) is a rare microangiopathy presenting with anemia, thrombocytopenia, and neurological deficits, occurring most often in various autoimmune diseases due to inhibition of ADAMTS13 by autoantibodies, as well as in pregnant women with or without an autoimmune substrate. In this article, we report two newly diagnosed TTP cases, who have not been published so far...

Juvenile idiopathic arthritis is an umbrella term covering several distinct categories that share common features. The European League Against Rheumatism and the Pediatric Rheumatology European Society have published a consensus article with recommendations to guide radiologists and clinicians in choosing the best imaging technique for each particular clinical setting. A reproducible, accurate, validated, and long-established scoring system to use in everyday practice for monitoring and predicting long-term response to therapy is still to be developed on MR imaging for each joint...

OBJECTIVE: To date, there are no standardized disease activity tools for systemic juvenile idiopathic arthritis (sJIA). We developed a core set of disease activity measures for sJIA. METHODS: We conducted a validation study in patients with sJIA recruited from 3 Canadian institutions. Disease activity scores were based on questionnaires, clinical factors, and laboratory measures. The physician's global assessment was our criterion standard. We determined the strength of association of each item with the criterion standard...

Systemic juvenile idiopathic arthritis (sJIA) is characterized by fever, arthritis, and other signs of systemic inflammation. Historically, sJIA was named Still's disease after George Frederic Still, who first reported patients. Individuals who manifest after the 16(th) birthday are diagnosed with adult onset Still's disease (AOSD). The pathophysiology of sJIA and AOSD are incompletely understood. Increased activation of inflammasomes and the expression of proinflammatory cytokines play a central role. S100 proteins, which can activate Toll-like receptors, thus, maintaining positive feedback loops, have also been detected at increased levels in sera from sJIA patients...

Juvenile idiopathic arthritis (JIA) is a rare inflammation with still unidentified cause. It can also be cause of fever of unknown origin. Diagnosis is made by eliminating infection, malignancy, and rheumatological diseases. In this report, case of a 5-year-old patient with symptoms of intermittent fever, areas of rash on the body, itching, and swelling, redness, and pain in the right and left ankle is described. Serological test results were negative for infectious agents, and malignancy was excluded. Patient was diagnosed with systemic JIA associated with intermittent fever, negative rheumatological markers and negative serology test results...

Macrophage activation syndrome (MAS) is a life-threating complication of systemic juvenile idiopathic arthritis (s-JIA). Steroid and cyclosporine (CsA) are effective for MAS, but, treatment for steroid- and CsA-resistant patients is still challenging. We report the case of steroid and CsA resistant s-JIA associated MAS misdiagnosed as Kawasaki disease (KD), who was successfully treated with the combination of plasma exchange (PE) and leukocytapheresis (LCAP) followed by plasma diafiltration (PDF). PE + LCAP effectively removed proinflammatory cytokines and reduced the number of peripheral white blood cells...

Juvenile idiopathic arthritis (JIA) and osteoarticular infection can cause nonspecific articular and periarticular complaints in children. Although contrast material-enhanced magnetic resonance imaging is the reference standard imaging modality, musculoskeletal ultrasonography (US) is emerging as an important adjunct imaging modality that can provide valuable information relatively quickly without use of radiation or the need for sedation. However, diagnostic accuracy requires a systemic approach, familiarity with various US techniques, and an understanding of maturation-related changes...

Systemic juvenile idiopathic arthritis (sJIA) and its most significant complication, macrophage activation syndrome (MAS), have traditionally been treated with steroids and non-steroidal anti-inflammatory medications. However, the introduction of biologic medications that inhibit specific cytokines, such interleukins 1 and 6, has changed the treatment paradigm for sJIA patients. In this review, we discuss the therapies currently used in the treatment of sJIA as well as novel targets and approaches under consideration, including mesenchymal stromal cell therapy and JAK inhibitors...

Antagonists of tumor necrosis factor-alpha (ATNF) are used for the treatment of multiple diseases such as psoriatic arthritis, Crohn's disease, ankylosing spondylitis and juvenile idiopathic arthritis, usually, when they are refractory to first-line treatment(1). The use of ATNF has been associated with the induction of autoimmune diseases such as systemic lupus erythematosus-like disease, vasculitis, sarcoidosis-like diseases and, recently, acute granulomatous tubulointerstitial nephritis. We report a case of acute nongranulomatous tubulointerstitial nephritis in an HLA-B27-positive patient with axial spondyloarthritis and Crohn's disease being treated with adalimumab...
