Differences in the SLE Clinical Phenotype by Age of Diagnosis
Background/Purpose: Systemic lupus erythematosus (SLE) is a prototypic autoimmune disease that is characterized by the presence of antinuclear autoantibodies, complement activation and the formation and…Abstract Number: 2684 • 2012 ACR/ARHP Annual Meeting
Cerebrospinal Fluid IL-6 and Anti-NMDA Receptor NR2 Antibodies As Surrogate Markers for CNS Disease Severity in SLE
Background/Purpose: Neuropsychiatric manifestations occur in approximately one-half of patients with SLE and may cause substantial impairment of quality of life as well as disability. Among…Abstract Number: 2126 • 2012 ACR/ARHP Annual Meeting
Changes of Serological Markers in the Course of Traditional and Biological Disease Modifying Therapy of Rheumatoid Arthritis
Background/Purpose: Rheumatoid factor (RF) and antibodies against citrullinated peptides (ACPA) are established markers in the diagnostic approach to rheumatoid arthritis (RA). Both auto-antibodies (AAB) also…Abstract Number: 1673 • 2012 ACR/ARHP Annual Meeting
Clinical Phenotypes of Caucasian Adult and Juvenile Dermatomyositis Patients with Anti-MDA5 Autoantibodies
Background/Purpose: Autoantibodies to MDA5 have been previously reported in Japanese patients with dermatomyositis (DM) and are associated with clinically-amyopathic DM and rapidly progressing interstitial lung…Abstract Number: 685 • 2012 ACR/ARHP Annual Meeting
Using a Library of Synthetic Autoantigen Mimics to Discover Biomarkers of Systemic Lupus Erythematosus
Background/Purpose: The natural history of systemic lupus erythematosus (SLE) is felt to evolve from a state of normal immunity to serologic autoimmunity and then…Abstract Number: 2097 • 2012 ACR/ARHP Annual Meeting
Adiponectin Is Associated with Pro-Inflammatory Cytokines in Autoantibody Positive First-Degree Relatives (FDRs) of Patients with Rheumatoid Arthritis
Background/Purpose: While adiponectin is generally considered an anti-inflammatory adipokine, it has also been shown to participate in active RA in inflammatory, matrix-destructive and fibrotic processes…Abstract Number: 1440 • 2012 ACR/ARHP Annual Meeting
Lupus-Prone Mice Demonstrate Enhanced Neutrophil Extracellular Trap Formation: Implications for Autoantibody Formation and Organ Damage
Background/Purpose: Recent evidence suggests that enhanced neutrophil extracellular trap (NET) formation—the programmed release of chromatin fibers decorated with granular antimicrobial peptides—is as an important activator…Abstract Number: 689 • 2012 ACR/ARHP Annual Meeting
Activation of the Interferon Pathway Is Dependent Upon Autoantibodies in African-American SLE Patients, but Not in European-American SLE Patients
Background/Purpose: Gene expression studies have been instrumental in defining important aspects of the complex immunological pathogenesis in systemic lupus erythematosus (SLE) which is a heterogeneous…Abstract Number: 1956 • 2012 ACR/ARHP Annual Meeting
A New Linked Set of Autoantibodies in Dermatomyositis: Anti-Mi-2 and Anti-Transcription Intermediary Factor (TIF) 1alpha
Background/Purpose: Myositis specific autoantibodies (MSA) produced in patients with polymyositis/dermatomyositis (PM/DM) are clinically useful biomarkers in diagnosis and management. Anti-Mi-2 antibodies that recognize nucleosome remodeling…Abstract Number: 1449 • 2012 ACR/ARHP Annual Meeting
Numbers of Splenic Long-Lived Plasma Cells in Autoimmune and Pre-Autoimmune Lupus Mice Are Linked to a Hyper-Responsive Variant of the Thrombopoietin Receptor and Enhanced Megakaryopoiesis
Background/Purpose: Autoantibodies contribute to the pathogenesis of the autoimmune disease Systemic Lupus Erythematosus (SLE) by stimulating the immune response. Further, deposits of immune complexes in…Abstract Number: 661 • 2012 ACR/ARHP Annual Meeting
Co-Localization of C-Reactive Protein, Immunoglobulin G and Complement in Renal Subendothelial Immune Deposits of Proliferative Lupus Nephritis Detected Using Immunogold Electron Microscopy
Background/Purpose: The pattern recognition molecules C-reactive protein (CRP) and complement protein 1q (C1q) are pivotal parts of the innate immune system and display relevant biological…
