The Level of RF or Anti-CCP Antibody Affect Ultrasound Synovial Findings in Patients with Rheumatoid Arthritis?
Background/Purpose: Positive for auto-antibodies such as rheumatoid factor (RF) and anti-citrullinated peptide antibodies (CCP) or having high autoantibody titers is associated with the progression of…Abstract Number: 1276 • ACR Convergence 2023
Multimorbidity Burden Predicts Lower Likelihood of Remission in Patients with Rheumatoid Arthritis
Background/Purpose: Seropositivity has historically been associated with poor disease outcomes in patients with rheumatoid arthritis (RA). Seronegative RA is on the rise and is associated…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: 0906 • ACR Convergence 2022
Patients with Seronegative Rheumatoid Arthritis Have a Different Ultrasound-assessed Joint Disease Phenotype Than Seropositive Patients
Background/Purpose: Seronegative rheumatoid arthritis (SNRA) tends to be less severe in its presentation and evolution than seropositive rheumatoid arthritis(SPRA), but controversy exists because there have…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: 0914 • ACR Convergence 2022
The Impact of Autoantibodies (RF and ACPA) on the Efficacy of Biological Disease-modifying Antirheumatic Drugs in Rheumatoid Arthritis: Meta-analysis of Randomized Controlled Trials
Background/Purpose: The impact of autoantibodies on the efficacy of bDMARDs in patients with rheumatoid arthritis (RA) is not yet clear. Despite the fact that this…Abstract Number: 1417 • ACR Convergence 2022
Clinical and Demographic Characteristics of Patients with RF+/ACPA+ RA and First-Line TNF Inhibitor versus Abatacept Treatment Choice in Real-World Clinical Practice
Background/Purpose: Early intensive treatment (tx) is an accepted paradigm in the tx of patients (pts) with RA with poor prognostic factors (eg, RF/ACPA seropositivity); however,…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: 1965 • ACR Convergence 2022
Autoantibodies Against a Specific 25-mer Peptide from P. Gingivalis Are Present in Sera of Patients with Rheumatoid Arthritis and Early Arthritis
Background/Purpose: The presence of rheumatoid factor (RF) or anti-cyclic citrullinated protein/peptide antibodies (ACPA) are included in the 2010 the ACR/EULAR classification criteria of rheumatoid arthritis…Abstract Number: 1989 • ACR Convergence 2022
Predictors of Flare in the RHEUmatoid Arthritis Medication TAPering (RHEUMTAP) Cohort
Background/Purpose: Long term use of conventional synthetic DMARDs (csDMARDs) and biologics in RA has clinical risks including infection and malignancy. Few RCTs and real-world studies…Abstract Number: 2043 • ACR Convergence 2022
What Does Isolated Anti-Ro52 Antibody Positivity Mean in Sjögren’s Syndrome?
Background/Purpose: Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease characterized by a triad of dryness, pain and fatigue in affected patients. Its diagnosis is…
