IL-4 signaling promotes IgE class switching through STAT6 activation and the induction of Ig germ-line epsilon (GLepsilon) transcription. Previously, we and others identified a transcription factor, Nfil3, as a gene induced by IL-4 stimulation in B cells. However, the precise roles of nuclear factor, IL-3-regulated (NFIL3) in IL-4 signaling are unknown.(More)
OBJECTIVE To compare the criteria for Wegener's granulomatosis (WG) of the American College of Rheumatology (ACR) with those of the European League Against Rheumatism/Pediatric Rheumatology European Society (EULAR/PRES) in a cohort of children with WG and other antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAVs), and to describe the(More)
OBJECTIVE To evaluate risk factors for subclinical atherosclerosis in a population of patients with pediatric systemic lupus erythematosus (SLE). METHODS In a prospective multicenter study, a cohort of 221 patients underwent baseline measurements of carotid intima-media thickness (CIMT) as part of the Atherosclerosis Prevention in Pediatric Lupus(More)
OBJECTIVE To formulate consensus treatment plans (CTPs) for induction therapy of newly diagnosed proliferative lupus nephritis (LN) in juvenile systemic lupus erythematosus (SLE). METHODS A structured consensus formation process was employed by the members of the Childhood Arthritis and Rheumatology Research Alliance after considering the existing medical(More)
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease, in which neuropsychiatric manifestations are a common cause of significant morbidity. The American College of Rheumatology has identified 19 distinct neuropsychiatric syndromes associated with SLE, although the 1982 American College of Rheumatology classification criteria for SLE(More)
OBJECTIVE Uveitis in children most commonly is associated with juvenile idiopathic arthritis. In addition to topical glucocorticoids, treatment may include systemic immunosuppressive agents. Tumor necrosis factor alpha (TNF-alpha) has been implicated in the pathogenesis of uveitis; therefore, TNF-alpha blockade seems to be a reasonable therapeutic option to(More)
OBJECTIVE Kawasaki disease (KD) has potentially serious cardiac complications including coronary artery aneurysms. Children who develop giant aneurysms (GA) are at increased risk of thrombosis and ischemia, and although longterm oral anticoagulation with warfarin is recommended, its efficacy has not been studied. We examined the longterm outcome of patients(More)
Paediatric patients with systemic lupus erythematosus (SLE) and antiphospholipid antibodies (aPL), specifically lupus anticoagulants (LAC) are at high risk of developing thromboembolic events (TE). Our objectives were to determine the prevalence of TE in paediatric SLE patients with LAC and to determine if anticoagulation was effective to decrease(More)
OBJECTIVE To describe clinical outcomes of juvenile idiopathic arthritis (JIA) in a prospective inception cohort of children managed with contemporary treatments. METHODS Children newly diagnosed with JIA at 16 Canadian paediatric rheumatology centres from 2005 to 2010 were included. Kaplan-Meier survival curves for each JIA category were used to estimate(More)
