OBJECTIVE To develop and validate a composite disease activity score for juvenile idiopathic arthritis (JIA), the Juvenile Arthritis Disease Activity Score (JADAS). METHODS The JADAS includes 4 measures: physician global assessment of disease activity, parent/patient global assessment of well-being, active joint count, and erythrocyte sedimentation rate.(More)
OBJECTIVE To develop diagnostic guidelines for macrophage activation syndrome (MAS) complicating systemic juvenile idiopathic arthritis (S-JIA). STUDY DESIGN We followed the classification criteria approach that is based on the comparison of patients with the index disease with patients with a "confusable" disease. The former group included 74 patients(More)
OBJECTIVE To develop and validate a clinical measure of articular and extraarticular damage in patients with juvenile idiopathic arthritis (JIA). METHODS The Juvenile Arthritis Damage Index (JADI), which is derived from physical examination and a brief review of the patient's clinical history, is composed of 2 parts: assessments of articular damage(More)
BACKGROUND Interleukin-1 is pivotal in the pathogenesis of systemic juvenile idiopathic arthritis (JIA). We assessed the efficacy and safety of canakinumab, a selective, fully human, anti-interleukin-1β monoclonal antibody, in two trials. METHODS In trial 1, we randomly assigned patients, 2 to 19 years of age, with systemic JIA and active systemic(More)
We report herein the results of the cross-cultural adaptation and validation into the Italian language of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile(More)
OBJECTIVE To assess the clinical response to interleukin-1 (IL-1) blockade and in vitro IL-1beta and IL-18 secretion in patients with systemic-onset juvenile idiopathic arthritis (JIA). METHODS Twenty-two patients with systemic-onset JIA were treated with the IL-1 receptor antagonist (IL-1Ra) anakinra. Monocytes from 18 patients and 20 healthy donors were(More)
OBJECTIVE We recently hypothesized that in the International League of Associations for Rheumatology (ILAR) classification of juvenile idiopathic arthritis (JIA), the presumably homogeneous patient group characterized by early onset of disease, a female predilection, the presence of antinuclear antibodies (ANA), asymmetric arthritis, and the risk for(More)
OBJECTIVE To investigate the rate of radiographic progression and identify prognostic factors of radiographic progression, radiographic damage, and physical disability in juvenile idiopathic arthritis (JIA). METHODS Ninety-four JIA patients with a median disease duration of 1.1 years were followed up prospectively for a median of 4.5 years. Bilateral(More)
OBJECTIVE To determine in a prospective analysis whether baseline demographic, clinical, and laboratory variables predict the outcome of intraarticular corticosteroid (IAC) injection of the knees in children with juvenile idiopathic arthritis (JIA). METHODS We studied consecutive patients who met the criteria for the diagnosis of JIA and received their(More)
OBJECTIVE To investigate the performance of the core set of outcome measures and the preliminary definition of improvement (PDI) in the assessment of response to methotrexate (MTX) treatment in children with juvenile chronic arthritis (JCA). METHODS Data were obtained from an open label, non-controlled trial designed to investigate the efficacy of MTX in(More)
