Background/Purpose: Systemic juvenile idiopathic arthritis (SJIA) associated lung disease (SJIA-LD) is an emerging and life-threatening clinical problem. Despite recent advances, there remain key unanswered questions…Abstract Number: 068 • 2023 Pediatric Rheumatology Symposium
Outcomes of Children with Uveitis Associated with Autosomal Dominant Neovascular Inflammatory Vitreoretinopathy (ADNIV)
Background/Purpose: Pediatric uveitis is commonly associated with rheumatic disease and can lead to sight-threatening complications if not properly treated. Systemic immunomodulatory therapy has dramatically changed…Abstract Number: 0014 • ACR Convergence 2022
The Expanded CD21 Low B Cell Subpopulation in Ankylosing Spondylitis Consists Mainly of Antigen-Inexperienced Cells
Background/Purpose: The role of B cells in the pathogenesis of ankylosing spondylitis (AS) remains relatively understudied. Nevertheless, available evidence shows presence of B cells at…Abstract Number: 0567 • ACR Convergence 2022
Gain-of-Function Mutations in Lyn Kinase Cause a Novel Autoinflammatory Disease with Small Vessel Vasculitis and Liver Fibrosis
Background/Purpose: Lyn kinase is a member of the Src family of tyrosine kinases that regulates innate and adaptive immune responses. Lyn C-terminal tail tyrosine residue,…Abstract Number: 1240 • ACR Convergence 2022
A Systematic Review and Meta-Analysis of Diagnostic Test Accuracy for the Diagnosis of Cardiac Sarcoidosis
Background/Purpose: Autopsy reports for patients with sarcoidosis have suggested that up to 25% have cardiac involvement, mostly undiagnosed. Given the limited diagnostic accuracy of endomyocardial…Abstract Number: 1930 • ACR Convergence 2022
Assessing the Number of Children Evaluated for Recurrent Fevers During the COVID-19 Pandemic in North America
Background/Purpose: The impact of the COVID-19 pandemic on the number of pediatric patients evaluated in North America for recurrent fevers and autoinflammatory diseases is unknown;…Abstract Number: 0010 • ACR Convergence 2022
The Inflammation Induced by Monosodium Urate and Calcium Pyrophosphate Crystals Depends on Osmolarity and Aquaporin Channels
Background/Purpose: The inflammation induced by monosodium urate (MSU) and calcium pyrophosphate (CPP) crystals is driven by interleukin (IL)-1β production. This later relies on NLRP3 inflammasome…Abstract Number: 0584 • ACR Convergence 2022
Non-Clinical Evaluations of Deucravacitinib and Janus Kinase Inhibitor Specificity in Inflammatory or Homeostatic Pathways
Background/Purpose: Deucravacitinib is a selective inhibitor of tyrosine kinase 2 (TYK2) that has shown clinical efficacy in psoriasis, PsA, and SLE. Deucravacitinib is an allosteric…
