Association Between Rheumatic Autoantibody Positivity and Immune-related Adverse Events
Background/Purpose: The advent of immune checkpoint inhibitors (ICIs) has revolutionized cancer therapy; however, their use can lead to off-target toxicities called immune-related adverse events (irAEs)…Abstract Number: 0461 • ACR Convergence 2021
Plasmablast-derived Autoantibodies from Individuals At-risk for RA That Target RA-relevant Antigens Are Polyreactive with Arthritogenic Bacteria
Background/Purpose: Circulating autoantibodies like ACPA frequently develop years before symptoms of RA, during which the individual is at-risk for disease. Several lines of evidence suggest…Abstract Number: 0790 • ACR Convergence 2021
Unraveling Heterogeneity Within ACPA-negative Rheumatoid Arthritis; The Subgroup of Patients with a Strong Clinical and Serological Response to Initiation of DMARD-treatment Favor Disease Resolution
Background/Purpose: Rheumatoid arthritis (RA) is a heterogeneous disease, especially ACPA-negative-RA. This is reflected by differences in long-term outcomes, ranging from refractory RA to sustained-DMARD-free-remission(SDFR; sustained…Abstract Number: 0007 • ACR Convergence 2021
Divergent Reactivities of Rheumatoid Factors and Anti-Modified Protein Antibodies Converge on IgG Epitopes
Background/Purpose: Rheumatoid arthritis (RA) patients often develop rheumatoid factors (RFs), antibodies that bind IgG Fc, and anti-modified protein antibodies (AMPAs), multi-reactive autoantibodies that commonly bind…Abstract Number: 0813 • ACR Convergence 2021
Improvement in Clinical Disease Activity and Patient-Reported Outcomes After 6 Months of Treatment with Abatacept, Stratified by Line of Therapy, in Patients with RA: Results from a Large, US, National Observational Study
Background/Purpose: RA is more responsive to treatment in the early stages of disease, and early treatment may lead to better long-term outcomes.1,2 Data on the…Abstract Number: 0012 • ACR Convergence 2021
A Novel Mechanism Linking Mucosal Bacteria with Autoantibody Responses in RA: Acetylated Bacterial Lysate as a Model Antigen
Background/Purpose: Rheumatoid arthritis (RA) is characterized by autoantibodies against post-translationally modified proteins (AMPA) such as citrullinated, carbamylated and acetylated proteins. Importantly, these antibodies are highly…Abstract Number: 1014 • ACR Convergence 2021
Enhanced Expression of Rheumatoid Arthritis Related Autoantibodies Following Airborne Endotoxin Exposure in the Setting of Collagen-Induced Arthritis
Background/Purpose: In addition to inflammatory arthritis, collagen-induced arthritis (CIA) recapitulates cardinal features of rheumatoid arthritis (RA) including autoreactive T cells, peptidyl-arginine deiminase expression, and citrullination…Abstract Number: 0021 • ACR Convergence 2021
Unique Alterations in Circulating T Peripheral Helper Cells Are Found in Different Ethnic Groups of ACPA+ Individuals Both At-risk for and with Classified RA
Background/Purpose: Production of autoantibodies following pathogenic T and B cell interactions precede the development of RA. T follicular helper (Tfh) cells and T peripheral helper…Abstract Number: 1214 • ACR Convergence 2021
Examining the Relationship Between Shared Epitope, ACPA Seropositivity, and Real-World Drug Effectiveness in Patients with Rheumatoid Arthritis
Background/Purpose: The shared epitope (SE) is an amino acid sequence motif coded by several HLA-DRB1 alleles that are overrepresented among people with rheumatoid arthritis (RA).…Abstract Number: 0033 • ACR Convergence 2021
Impaired Adipose Tissue Function in Rheumatoid Arthritis: Association with Autoimmunity, Disease Activity and Therapeutic Response
Background/Purpose: 1) to evaluate the relationship among adipose tissue dysfunction, autoimmunity and disease activity in rheumatoid arthritis (RA) patients; 2) to analyze the direct effect…Abstract Number: 1243 • ACR Convergence 2021
Real World Validation of a Rule to Predict Response to Sarilumab in Patients with Rheumatoid Arthritis: Analysis from the RISE Registry
Background/Purpose: Accurately identifying patients who may respond better to a specific drug or mechanism of action could improve rational selection of medications to optimize clinical…Abstract Number: 0034 • ACR Convergence 2021
Immune Complexes Contain Novel Acetylated Antigens in the Synovial Fluid of RA Patients
Background/Purpose: Rheumatoid arthritis (RA) is an autoimmune disease characterized by genetic predisposition and associated immunological features including the production of autoantibodies against various epitopes. Several…Abstract Number: 1648 • ACR Convergence 2021
Increasing Rates of Positivity of Autoantibodies Indicates a Shorter Time-to-Diagnosis of Future Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) has a ‘pre-RA’ period that can be defined by elevations in autoantibodies to citrullinated protein antigens (ACPA) and rheumatoid factor (RF)…Abstract Number: 0037 • ACR Convergence 2021
Identification and Validation of Four Circulating Autoantibodies Associated with the ACPA Status in Early Rheumatoid Arthritis
Background/Purpose: The presence of anti-citrullinated protein antibodies (ACPAs) is a highly specific hallmark of rheumatoid arthritis (RA), that is present also in early disease. However,…Abstract Number: 1652 • ACR Convergence 2021
Symptom Burden in Anti-citrullinated Protein Antibody Positive Individuals At-risk for Rheumatoid Arthritis Is Changing over Time and Comparable to Patients with Early Rheumatoid Arthritis
Background/Purpose: Symptom burden in individuals at risk for developing rheumatoid arthritis (RA) - positive for anti-citrullinated peptide antibodies (ACPA) and musculoskeletal complaints - has not…
