The Dynamics of the Gut Microbiome in Rheumatoid Arthritis Susceptibility: A Cross-Sectional and Longitudinal Observational Study
Background/Purpose: Multiple compositional shifts of gut microbiota have been identified within the rheumatoid arthritis (RA) disease continuum, encompassing both established RA and at-risk individuals (including…Abstract Number: 2121 • ACR Convergence 2023
Clinical Significance of Negative Seroconversion of Anti-CCP and Anti-Mutated Citrullinated Vimentin Antibodies in Patients with Rheumatoid Arthritis
Background/Purpose: Anti-cyclic citrullinated peptide antibody (anti-CCP Ab) positivity is closely associated with bone destruction in rheumatoid arthritis (RA) patients, but the correlation between the Ab…Abstract Number: 2141 • ACR Convergence 2023
Glucocorticoid Treatment in Early Rheumatoid Arthritis Is Associated with Increased Proprotein Convertase Subtilisin/kexin Type 9 (PCSK9) Levels: A Post-hoc Analysis of a Randomized Controlled Trial (NORD-STAR)
Background/Purpose: Rheumatoid arthritis (RA) is associated with an elevated risk for developing atherosclerotic cardiovascular disease (CVD). Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a key…Abstract Number: 1761 • ACR Convergence 2022
Treatment Patterns of Disease-Modifying Anti-Rheumatic Drugs by Serostatus Among Patients with Rheumatoid Arthritis
Background/Purpose: Previous studies suggest that seropositive and seronegative rheumatoid arthritis (RA) patients may respond differently to disease-modifying anti-rheumatic drugs (DMARDs). However, little is known about…Abstract Number: 0533 • ACR Convergence 2022
Sputum RA-Associated Autoantibodies Independently Associate with Future Development of Classified RA in an At-Risk Cohort of Individuals with Systemic Anti-CCP Positivity
Background/Purpose: Presence of systemic anti-CCP-IgG antibodies in individuals without inflammatory arthritis (IA) strongly predicts developing future classified RA. However, published data also demonstrate that 50-70%…Abstract Number: 0616 • ACR Convergence 2022
Serum Proteomic Networks Associate with Pre-clinical Rheumatoid Arthritis Autoantibodies and Longitudinal Outcomes
Background/Purpose: The detection of anti-citrullinated protein antibodies (ACPA) is associated with increased risk for development of future Rheumatoid Arthritis (RA). The biological events that underpin…Abstract Number: 0714 • ACR Convergence 2022
Real-World Treatment Effectiveness of Disease-Modifying Anti-Rheumatic Drugs by Serostatus Among Patients with Rheumatoid Arthritis
Background/Purpose: Serostatus may be associated with different responses to treatment with biologic disease-modifying anti-rheumatic drugs (DMARD) or Janus kinase inhibitors (JAKi) in patients with rheumatoid…Abstract Number: 0766 • ACR Convergence 2022
CCP+ Immune Checkpoint Inhibitor Arthritis Patients Have Less ACPA Epitope Expansion Than CCP+ Rheumatoid Arthritis Patients
Background/Purpose: Immune checkpoint inhibitors (ICI) have markedly improved the treatment of many advanced cancers; however, they can result in immune-related adverse events (irAE) including ICI-inflammatory…Abstract Number: 0883 • ACR Convergence 2022
Serum Cholesterol Loading Capacity on Macrophages Is Dependent on Oxidized Low-density Lipoprotein and Regulated by Seropositivity and C-reactive Protein in Patients with Rheumatoid Arthritis
Background/Purpose: Excessive cholesterol accumulation in macrophages underlies foam cell formation, initiation and progression of atherosclerosis. Low-density lipoprotein (LDL) oxidation and unregulated uptake by macrophages are…Abstract Number: 0891 • ACR Convergence 2022
Rheumatoid Arthritis and the Rheumatic Disease Comorbidity Index (RDCI): Its Impact on Disease Activity
Background/Purpose: Comorbid conditions in the setting of rheumatoid arthritis (RA) play an important role in predicting disease activity and functional impairment (1). Application of a…Abstract Number: 1203 • ACR Convergence 2022
The Association Between Anti-Citrullinated Peptide Antibodies and Subclinical Interstitial Lung Disease in Community-Dwelling Adults: The Multi-Ethnic Study of Atherosclerosis
Background/Purpose: We previously demonstrated a significant association between serum anti-CCP levels and prevalence of interstitial lung abnormalities (ILA) in community-dwelling adults. A greater number of…Abstract Number: 1405 • ACR Convergence 2022
In Contrast to Anti-CCP, Then MMP Degraded and Citrullinated Vimentin (VICM) Is Both a Diagnostic and Treatment Response Biomarker
Background/Purpose: The degree of protein citrullination and degradation by matrix metalloproteinases (MMP) play a central role in the pathology of rheumatoid arthritis (RA). Autoantibodies are…Abstract Number: 1411 • ACR Convergence 2022
Predictors of Achieving Clinical Remission in ACPA-positive RA-patients Treated with Abatacept and Methotrexate or Methotrexate Monotherapy
Background/Purpose: With a wide range of disease modifying treatment available, clinical remission is frequently achieved in rheumatoid arthritis (RA). Although a proportion of RA-patients achieves…Abstract Number: 1604 • ACR Convergence 2022
Hydroxychloroquine Does Not Prevent the Future Development of Rheumatoid Arthritis in a Population with Baseline High Levels of Antibodies to Citrullinated Protein Antigens and Absence of Inflammatory Arthritis: Interim Analysis of the StopRA Trial
Background/Purpose: The Strategy to Prevent the Onset of Clinically-Apparent Rheumatoid Arthritis (StopRA) (ClinicalTrials.gov NCT02603146) is a randomized, double-masked, placebo-controlled, multi-center (20 sites) clinical trial evaluating…
