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: 0389 • ACR Convergence 2023
The Role of anti-CCP3 Antibodies in anti-CCP2 Antibody Negative Patients with Musculoskeletal Symptoms
Background/Purpose: To investigate, in primary care, whether testing anti-CCP3 antibodies in anti-CCP2 negative individuals with musculoskeletal (MSK) symptoms, improved the prediction of inflammatory arthritis (IA)/rheumatoid…Abstract Number: 0530 • ACR Convergence 2022
Abatacept Significantly Reduces Subclinical Inflammation During Treatment (6 Months), This Persists After Discontinuation (12 Months), Resulting in a Delay in the Clinical Development of RA in Patients at Risk of RA (The ARIAA Study)
Background/Purpose: Development of the clinical phase of rheumatoid arthritis (RA) is preceded by an autoimmune phase, characterized by the presence of anti-citrullinated protein antibodies (ACPA),…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: 0910 • ACR Convergence 2022
Rheumatoid Arthritis Associated Interstitial Lung Disease: The Role of Non-Criteria Autoantibodies
Background/Purpose: Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic joint inflammation. RA-associated interstitial lung disease (ILD) is the most frequent and severe extra-articular…Abstract Number: 0938 • ACR Convergence 2022
Baseline Predictors of Disease Flare upon csDMARD Withdrawal in Patients with Rheumatoid Arthritis in Sustained Remission After DAS-driven Therapy: Role of the Systemic Autoimmune Status and Peripheral Joint Ultrasound Across a 5-year Follow-up
Background/Purpose: Early diagnosis and treat-to-target strategies with synthetic conventional DMARDs in rheumatoid arthritis (RA) have allowed the achievement of remission in a significant percentage of…Abstract Number: 1230 • ACR Convergence 2021
Impact of Serologic Status on Clinical Responses to Upadacitinib or Abatacept in Patients with Rheumatoid Arthritis and Prior Inadequate Response to Biologic DMARDs: Sub-Group Analysis from the Phase 3 SELECT-CHOICE Study
Background/Purpose: In patients with RA who had a prior inadequate response or intolerance to biologic DMARDs, the oral Janus kinase inhibitor, upadacitinib (UPA), demonstrated superiority…Abstract Number: 0766 • ACR Convergence 2020
ACPA and Cholesterol Titers as Predictors of Good Clinical Response at One Year in an Argentine Cohort
Background/Purpose: Autoantibody positivity, erosions, activity level, and functional capacity were classically defined as poor prognosis. Paradoxically, many of them also predict a good response to…Abstract Number: 0771 • ACR Convergence 2020
Factors Associated to Clinical and Radiographic Disease Progression in Patients with Early RA and First-degree Relatives: A 1-year Follow-up
