Decreased Discontinuation and Switching of B/tsDMARD Therapy in RA Patients When Treatment Is Aligned with a Molecular Signature Response Classifier: An Analysis from the Study to Accelerate Information of Molecular Signatures (AIMS)
Background/Purpose: Rheumatoid arthritis (RA) patients with inadequate response to methotrexate often experience trial-and-error treatment selection due to a lack of guidance from clinical guidelines or…Abstract Number: 1600 • ACR Convergence 2022
The Impact of Second-Line Therapeutic on Disease Control After Discontinuation of First Line TNF Inhibitor in Patients with PsA: Analysis from the CorEvitas Psoriatic Arthritis/Spondyloarthritis Registry
Background/Purpose: While evidence in patients (pts) with RA suggests that switching to a therapy with a different mechanism of action (MOA) may be more effective…Abstract Number: 1606 • ACR Convergence 2022
An Expanded Anti-citrullinated Protein Antibody Profile Derived Using Unsupervised Machine Learning Predicts Treatment Responses to Biologic Therapies in Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) treatments have advanced with the availability of biologic therapies. Despite these advances, 30-40% of patients receiving a biologic do not adequately…Abstract Number: 1622 • ACR Convergence 2022
TNF Receptor 1 Drives Murine Pulmonary Arterial Hypertension and Is Characterized by Loss of Capillary Endothelial Cells and Pericytes, Smooth Muscle Cell Proliferation, and Alterations in Fibroblast Phenotype
Background/Purpose: We previously demonstrated that TNF-transgenic (TNF-Tg) mice have findings consistent with connective-tissue disease associated pulmonary arterial hypertension (CTD-PAH), and that this pathology is mediated…Abstract Number: 0185 • ACR Convergence 2021
Phase 1 Study Results of GS-5718, an Oral IRAK4-Inhibitor: Pharmacodynamics of Single and Multiple Doses of GS-5718 in Healthy Subjects
Background/Purpose: Adaptive and innate immune pathways are involved in inflammation and pathogenesis of autoimmune diseases including Rheumatoid Arthritis (RA) and Lupus Erythematosus (LE). Immune complexes…Abstract Number: 1891 • ACR Convergence 2021
Variable Effects of Testosterone on Male versus Female Derived Macrophages in Inflammatory Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is a chronic inflammatory joint disease that is female predominant. The TNF-transgenic (TNF-Tg) mouse model of RA also develops a sexually…Abstract Number: 0204 • ACR Convergence 2021
Risk of Hepatitis B Virus Reactivation in Patients with Immune-Mediated Inflammatory Diseases Receiving Biologics: Focus on the Timing of Biologics After Prophylactic Anti-viral Agents
Background/Purpose: Prophylactic anti-viral therapy is required in patients with hepatitis B virus (HBV) infection receiving biologics because of the high risk of HBV reactivation. However,…Abstract Number: 0246 • ACR Convergence 2021
Macrophage Activating Syndrome in Patients with Systemic Juvenile Idiopathic Arthritis Treated with Biological Drugs
Background/Purpose: Systemic Juvenile Idiopathic Arthritis (SJIA) is the most acute and severe form of JIA. Despite the substantial evidence supporting the effectiveness of biologic drugs…Abstract Number: 0451 • ACR Convergence 2021
Tumor Necrosis Factor Inhibitors Show a Delayed Effect on Radiographic Sacroiliitis Progression in Patients with Early Axial Spondyloarthritis: 10-Year Results from the German Spondyloarthritis Inception Cohort
Background/Purpose: Observational cohort studies have shown that there is low, but still detectable progression level in radiographic sacroiliitis, which might also have an impact on…Abstract Number: 0511 • ACR Convergence 2021
Tumor Necrosis Factor-α Modulates Endothelial-to-mesenchymal Transition and Increases Protein Tyrosine Phosphatase 1B
Background/Purpose: Endothelial dysfunction is a hallmark in the pathogenesis of many inflammatory diseases. The endothelial-to-mesenchymal transition (EndoMT) is a process where endothelial cells lose their…Abstract Number: 0514 • ACR Convergence 2021
Extracellular Sulfatase-2 Mediates TNF-α Inflammatory Signaling in Human Rheumatoid Arthritis Synovial Fibroblasts
Background/Purpose: TNF-α drives RA synovial fibroblast (RASF)-mediated hyperplasia and joint tissue destruction. Extracellular sulfatase-2 (Sulf-2) influences receptor/ligand binding and subsequent signaling of chemokines, cytokines, and…
