ISSN 1758-4272 Int. J. Clin. Rheumatol. (2014) 9(2), 135–146 Juvenile idiopathic arthritis is the most common pediatric rheumatic condition. Advances in identification of cytokines, inflammatory networks and genes involved in the pathogenesis of the disease may lead us towards a more personalized approach to treatment and a biological classification of juvenile idiopathic arthritis. Identificat...

Patient-reported outcome (PRO) measures provide a valuable window into how patients with juvenile idiopathic arthritis and their parents perceive their functioning, quality of life, and medication side effects in the context of their disease and treatment. Momentum behind adoption of PRO measures is increasing as these patient-relevant tools capture information pertinent to taking a patient-cen...

Systemic-onset juvenile idiopathic arthritis (SoJIA) is a form of juvenile idiopathic arthritis (JIA) that typically presents with prominent systemic features and accounts for approximately 10-15% of children with JIA. Pro-inflammatory cytokine pathways are thought to be involved in its pathogenesis, including interleukin-1 (IL-1) and interleukin-6 (IL-6), and laboratory tests demonstrate a pro...

Systemic-onset juvenile idiopathic arthritis (SoJIA), sometimes called Still's disease, is a systemic inflammatory disease classified within the spectrum of juvenile idiopathic arthritis (JIA). It is an orphan disease with often a chronic course and a major impact on the affected children and their families. This disorder is unique in terms of clinical manifestations, prognosis and response to ...

Popliteal cysts occur commonly both in normal and arthritic knees. Most cysts are formed by distension of the medially situated semimembranosus bursa. Herein, we describe three children with juvenile idiopathic arthritis and ruptured popliteal cysts which produced leg complaints. Ultrasound and magnetic resonance imaging were performed in the diagnosis of all cases for better evaluation of the ...

CONTEXT Patients with refractory juvenile idiopathic arthritis can benefit from aggressive therapy. CASE REPORT We followed the clinical course of 4 patients (2 male, 2 female) aged 9.1-17.8 years (mean of 14.5 years) with polyarticular onset of juvenile rheumatoid arthritis and one 16-year-old boy with juvenile spondyloarthropathy associated with inflammatory bowel disease. All the juvenile ...

Systemic juvenile idiopathic arthritis (sJIA) constitutes a small part of juvenile idiopathic arthritis (JIA), yet has a disproportionally higher rate of mortality. Despite being grouped under JIA, it is considered to be a multifactorial autoinflammatory disease. The objective of this paper is to review the epidemiology, pathogenesis, genetics, clinical manifestations, complications, therapy, p...

Background: Foot and ankle problems are a common but relatively neglected manifestation of juvenile idiopathic arthritis. Studies of medical and non-medical interventions have shown that clinical outcome measures can be improved. However existing data has been drawn from small non-randomised clinical studies of single interventions that appear to under-represent the adult population suffering f...

OBJECTIVES To assess the presence of anti-cyclic citrullinated peptide antibodies in a cohort of patients with juvenile idiopathic arthritis. METHODS Anti-cyclic citrullinated peptide antibodies was tested for with an enzyme linked immunoabsorbent assay (ELISA) in serum samples of patients from the Hospital de Clínicas de Porto Alegre, all less than 18 years old and with previous diagnosis fo...

Over the past decades, the role of exercise training in rheumatic diseases has been largely explored. Currently, physical activity is well known to benefit patients with osteoporosis, osteoarthritis, systemic lupus erythematosus, systemic sclerosis, idiopathic inflammatory myopathy, fibromyalgia and rheumatoid arthritis. Therefore, exercise training has been considered a valuable tool for treat...
