Influence of Rheumatoid Factor on Serum Drug Levels of TNF Inhibitors with Different Structures in Rheumatoid Arthritis
Background/Purpose: Elevated rheumatoid factor (RF) in patients with rheumatoid arthritis (RA) is associated with higher disease activity. A significantly lower efficacy of TNF inhibitors (TNFi)…Abstract Number: 1754 • ACR Convergence 2023
Novel and Unique Rheumatoid Factors Cross-React with Viral Epitopes in COVID-19
Background/Purpose: Rheumatoid factors (RFs), polyreactive antibodies canonically known to bind two conformational epitopes of IgG, are a hallmark of rheumatoid arthritis but also can arise…Abstract Number: 1772 • ACR Convergence 2023
Rheumatoid Arthritis-Specific Rheumatoid Factors Develop in Some COVID-19 Patients
Background/Purpose: Rheumatoid factors (RFs), antibodies canonically known to bind two conformational epitopes of IgG Fc, are a hallmark of rheumatoid arthritis (RA) but also can…Abstract Number: 1915 • ACR Convergence 2023
Scleritis and Development of Autoimmune Disease: A Case Series
Background/Purpose: Scleritis involves inflammation of the sclera caused by trauma, infections, or autoimmune conditions. The purpose of our study was to understand the relationship between…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: 2148 • ACR Convergence 2023
Do High RF Titers Impact Response to TNF Inhibitors? Comparison of Certolizumab Pegol and Adalimumab in Patients with RA and High Titers of RF: A Post Hoc Analysis of a Phase 4 Trial
Background/Purpose: In patients with RA, high RF titers are considered a poor prognostic factor and are associated with higher disease activity, risk of radiographic progression,…Abstract Number: 2183 • ACR Convergence 2023
Evolution of Lymphoma Predictors in Primary Sjogren’s Syndrome by Data Driven Analysis in Harmonized Patients
Background/Purpose: Lymphoma is the most serious complication of primary Sjogren'ssyndrome (pSS), occurring as a late sequel during disease course. So far, lymphomapredictors have been identified…Abstract Number: 0205 • ACR Convergence 2023
Changes in Serum Rheumatoid Factor Following Eradication of Hepatitis C Virus Infection with Interferon or Direct Antiviral Therapy
Background/Purpose: Chronic hepatitis C virus (HCV) infection is associated with autoimmune extrahepatic manifestations including increased production of autoantibodies such as rheumatoid factor (RF). Prior to…Abstract Number: 0080 • ACR Convergence 2022
Utilization of Biologic and Targeted Disease Modifying Antirheumatic Therapy in Patients with Rheumatoid Arthritis and Breast Cancer
Background/Purpose: Biologic and targeted synthetic disease modifying antirheumatic drugs (bDMARD and tsDMARD) are immunosuppressant, and there have been concerns that they might impact tumor immunity…
