Interpretation of Disease-specific Questionnaires on Disease Activity, Functional Capacity and Quality of Life in Daily Practice in Axial Spondyloarthritis
Background/Purpose: In axial spondyloarthritis (axSpA), assessment of disease activity and physical function in clinical studies relies on patient-reported outcomes (PRO) such as patient's global, BASDAI,…Abstract Number: 1744 • ACR Convergence 2023
Histological and Molecular Comparison in the Synovial Tissue of Patients with Active Rheumatoid Arthritis to Remission
Background/Purpose: Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease which leads to local and systemic manifestations. Subsequently, the inflamed synovium drives the destruction of…Abstract Number: 1743 • ACR Convergence 2023
Individuals At-risk for and with Rheumatoid Arthritis Have Elevated Fecal Concentrations of Arthritogenic Subdoligranulum didolesgii Correlating with CCP3 Antibodies
Background/Purpose: Our prior investigation identified a specific strain of Subdoligranulum didolesgii, S. dido7, to which dual IgA/IgG family plasmablast-derived monoclonal autoantibodies from individuals at-risk for…Abstract Number: 2211 • ACR Convergence 2023
A Two-year Comparison of Back Pain and Morning Stiffness in Axial Spondyloarthritis and Non-axial Spondyloarthritis Chronic Back Pain Patients in the Spondyloarthritis Caught Early (SPACE) Cohort
Background/Purpose: Treatment of axial spondyloarthritis (axSpA) has been shown to improve symptoms of the disease such as back pain (BP) and morning stiffness (MS). As…Abstract Number: 2215 • ACR Convergence 2023
Can Axial Spondyloarthritis Unequivocally Be Diagnosed by Rheumatologists in Patients with Chronic Back Pain of Less Than Two Years Duration? The Primary Outcome of the Two-year SPondyloArthritis Caught Early (SPACE) Cohort
Background/Purpose: Unacceptable diagnostic delay in axial Spondyloarthritis (axSpA) remains an issue. In 2008, the longitudinal SPondyloArthritis Caught Early (SPACE)-cohort started to assess the prevalence of…Abstract Number: 1604 • ACR Convergence 2023
First and Recurrent Thrombosis Risk After 4,454 Patient-Years of Follow-Up: Prospective Results from the AntiPhospholipid Syndrome Alliance for Clinical Trials and InternatiOnal Networking (APS ACTION) Clinical Database and Repository (“Registry”)
Background/Purpose: The APS ACTION Registry was created to study the natural course of disease over 10 years in persistently antiphospholipid antibody (aPL)-positive patients with or…Abstract Number: 2217 • ACR Convergence 2023
Gender Disparities in Disease Activity Scores and Treatment Response Among Patients with Axial Spondyloarthritis
Background/Purpose: The assessment of disease activity in axial spondyloarthritis (axSpA) heavily relies on patient-reported outcomes. It is well-established that gender can influence these outcomes. Accordingly,…Abstract Number: 1720 • ACR Convergence 2023
Successful Treatment of Rheumatoid Arthritis in Mice Using Cenerimod, a Selective Modulator of the S1P1 Receptor, Demonstrates the Potential Benefits of S1P1 Receptor Immunomodulation for Rheumatic Diseases
Background/Purpose: Discovery of the essential role of S1P signaling in regulating lymphocyte trafficking led to the development of S1P receptor modulators for the treatment of…Abstract Number: 1607 • ACR Convergence 2023
Autoantibodies to Transcription Factor a Mitochondria Link Mitochondrial Damage and Thrombosis in Systemic Lupus Erythematosus
Background/Purpose: Upon activation with interferon (IFN) and RNP-immune complexes, defective mitophagy in neutrophils results in the release of mtDNA in complex with transcription factor A…Abstract Number: 1185 • ACR Convergence 2023
Soluble Buffered Alendronate After Denosumab Discontinuation in Erosive Hand OA Patients
Background/Purpose: In osteoporotic patients, discontinuation of denosumab is associated with a rapid increase in bone turnover and bone loss. Denosumab was recently proven to have…Abstract Number: 1608 • ACR Convergence 2023
Plasma Proteomic Profiling in Antiphospholipid Antibody-positive Patients with Different Clinical Phenotypes: Results from the Antiphospholipid Syndrome Alliance for Clinical Trials and International Networking (APS ACTION) Registry
Background/Purpose: Antiphospholipid syndrome (APS) is an autoimmune disease with thrombotic and obstetric complications arising via a model of immunothrombosis. Patients may present with a spectrum…Abstract Number: 1620 • ACR Convergence 2023
Cardiovascular Risk and Fracture Risk Among Women Initiating Treatment with Romosozumab or Denosumab
Background/Purpose: Romosozumab (romo) and denosumab (dmab) are recommended for postmenopausal women with osteoporosis (OP) at high risk of fracture. The U.S. prescribing information includes a…
