Individual RA-Derived Monoclonal Anti-Citrullinated Protein Autoantibodies (ACPA) Have Extensive Citrulline Multi-Reactivity Demonstrated By a Large-Scale Protein Array Platform
Background/Purpose: The presence of serum IgG anti-citrullinated protein autoantibodies (ACPA) in rheumatoid arthritis (RA), is associated with more aggressive disease progression. Although ACPA have been…Abstract Number: 77 • 2018 ACR/ARHP Annual Meeting
Single Nucleotide Polymorphism in the Gene Encoding Peptidylarginine Deiminase 4 Correlates with Reduced Neutrophil Extracellular Traps and Anti-Histone Antibodies in Rheumatoid Arthritis
Background/Purpose: In neutrophils, peptidylarginine deiminase 4 (PAD4) citrullinates histones allowing chromatin unraveling and neutrophil extracellular trap (NET) formation. NETs are increased and display proteins targeted…Abstract Number: 79 • 2018 ACR/ARHP Annual Meeting
Rheumatoid Arthritis (RA)-Associated Autoantibodies Are Present in the Periodontal Exudate of Patients with and without RA
Background/Purpose: Seropositivity for anti-citrullinated protein antibodies (ACPA) and rheumatoid factor (RF) is a hallmark of RA and can be present years before clinical onset has…Abstract Number: 554 • 2018 ACR/ARHP Annual Meeting
Are There Any Associations between ANA Development and Poor Treatment Response to Bdmards in RA Patients?
Background/Purpose: It has been well known that anti-TNF-α treatment for RA patients is associated with ANA development. We previously reported that ANA development along with…Abstract Number: 1441 • 2018 ACR/ARHP Annual Meeting
Diagnostic Performances of Antibodies Against Carbamylated Proteins in US Based Populations with Rheumatoid Arthritis and Other Autoimmune Rheumatic Diseases
Background/Purpose: Recently, antibodies directed against carbamylated antigens (anti-CarP antibodies) were identified in rheumatoid arthritis (RA). Studies have established the predictive and prognostic value of this…Abstract Number: 393 • 2017 ACR/ARHP Annual Meeting
The Role of Follicular Helper 17 T Cells in Glucose-6-Phosphate Isomerase Induced Arthritis
Background/Purpose: Follicular helper T (Tfh) cell is a novel T cell subset which promotes follicular B cell activation, differentiation to plasma cell and antibody production.…Abstract Number: 1363 • 2017 ACR/ARHP Annual Meeting
Disease Duration and Shared Epitope, but Not Smoking History, Are Associated with Peptidylarginine Deiminase 4-Antibody Development in Rheumatoid Arthritis
Background/Purpose: Clinical characteristics and biomarkers help clinicians predict disease features in rheumatoid arthritis (RA). Both peptidylarginine deiminase 4 (PAD4) antibodies and smoking have been associated…Abstract Number: 1402 • 2017 ACR/ARHP Annual Meeting
In RA, Becoming Seronegative over the 1st Year of DMARD Treatment Does Not Improve Chances of Drug-Free Remission in the Long-Term
Background/Purpose: Patients with RA harbor autoantibodies of various isotypes and directed against several post-translational modifications. Baseline seropositivity is a poor prognostic factor for sustained drug-free…Abstract Number: 1971 • 2017 ACR/ARHP Annual Meeting
Association between Genetic Variants and the Presence of Rheumatoid Arthritis-Related Autoimmunity and Progression to Classified Rheumatoid Arthritis in an at-Risk Population
Background/Purpose: Rheumatoid arthritis (RA) is an autoimmune disease characterized by the presence of RA-related autoantibodies prior to the development of clinical disease. While HLA-shared epitope…Abstract Number: 2916 • 2017 ACR/ARHP Annual Meeting
The Presence of a Large Number of Autoantibodies at Baseline Is Favourable for Early Treatment Response but Unfavourable for Drug-Free Remission in RA Patients
Background/Purpose: The autoantibody response of seropositive RA is very diverse and consists of various numbers of isotypes and antibodies to multiple post-translational modifications. It is…Abstract Number: 2113 • 2016 ACR/ARHP Annual Meeting
Anti-Carbamylated Protein Antibody (cross)-Reactivity Against Multiple Carbamylated Protein Antigens
Background/Purpose: Antibodies that target carbamylated proteins (anti-CarP) have been implicated in rheumatoid arthritis and are known to associate with joint damage. Furthermore, these autoantibodies…Abstract Number: 550 • 2015 ACR/ARHP Annual Meeting
Can Anti-TNF-Induced Autoantibody Conversion be Reversed By Switching to Abatacept Therapy in Patients with RA on Background MTX?
Background/Purpose: Anti-TNF therapy for RA is associated with antinuclear (ANAs) and anti-double-stranded DNA (anti-dsDNA) autoantibodies.1,2 The effect of biologics on autoantibody-positive patients is unknown. We…Abstract Number: 578 • 2015 ACR/ARHP Annual Meeting
Study of the Production of Antinuclear Antibodies and Anti-Ds DNA Antibodies in Rheumatoid Arthritis Patients Treated with TNF Inhibitors
Background/Purpose: The production of autoantibodies, such as anti-nuclear antibodies (ANA) and anti-ds DNA antibodies (anti-DNA), is commonly observed in patients who have been treated with…Abstract Number: 1212 • 2015 ACR/ARHP Annual Meeting
Investigation of Vitamin D Supplement Use, Rheumatoid Arthritis-Related Autoimmunity and Joint Signs Among Those at Increased Risk for the Development of Rheumatoid Arthritis
