Are Serological Protease-mediated Peptides of Tissue Remodeling and Inflammation the New Disease Activity Biomarkers in Psoriatic Arthritis Patients?
Background/Purpose: Inflammatory and degenerative processes in the joint tissues are hallmarks of patients with psoriatic arthritis (PsA). Here, proteases play a major role in remodeling…Abstract Number: 1986 • ACR Convergence 2022
Early-stage Rheumatoid Arthritis Patients with High Levels of Type III Collagen Are Less Likely to Respond to Anti-IL6R Treatment
Background/Purpose: Rheumatoid arthritis (RA) is a chronic, autoimmune disease, which normally is characterized by inflammation and thickening of the synovial membrane leading to swollen and…Abstract Number: 2044 • ACR Convergence 2022
Abnormalities of Extracellular Matrix Modeling Gene Expression in Salivary Gland Epithelial Cells of Patients with Sjögren’s Syndrome
Background/Purpose: Salivary gland epithelial cells (SGECs) are not only the target of autoimmunity in primary Sjögren's syndrome (pSS). SGECs may interact with lymphocytes and therefore…Abstract Number: 2129 • ACR Convergence 2022
Serum Extracellular Matrix Biomarkers Identify Response to Guselkumab in Psoriatic Arthritis; Post-hoc Analysis from a Phase 3, Randomized, Double-blind, Placebo-controlled Study Through 2 Years
Background/Purpose: Psoriatic arthritis (PsA) is a progressive, joint-degenerative inflammatory disease with cartilage destruction, bone erosion and growth, and synovitis. Extracellular matrix (ECM) remodeling is also…Abstract Number: 2176 • ACR Convergence 2022
Novel Tissue Turnover Blood Markers Are Associated with Pulmonary Arterial Hypertension and NYHA Stages in Patients with Systemic Sclerosis
Background/Purpose: Systemic sclerosis (SSc) is characterized by vasculopathy and fibrosis of the skin and internal organs. Cardiac involvement, pulmonary arterial hypertension (PAH), and interstitial lung…Abstract Number: 0539 • ACR Convergence 2021
Vgll3-transgenic Autoimmune Mice Display Features of Cutaneous Fibrosis
Background/Purpose: Fibrosis is characterized by collagen deposition, fibro/myofibroblast accumulation, and extracellular matrix remodeling and can lead to disfiguring skin changes. In cutaneous lupus, scar formation…Abstract Number: 1128 • ACR Convergence 2021
Inter-relationships Between Multiple Joint Osteoarthritis and Collagen Biomarkers in Men: The Johnston County Osteoarthritis Project
Background/Purpose: To determine inter-relationships between blood-based collagen formation and degradation biomarkers and multiple joint osteoarthritis (MJOA) phenotypes in a community-based cohort.Methods: Data were from Johnston…Abstract Number: 1475 • ACR Convergence 2021
Long Term Compressive Loading Modulates the Extracellular Matrix Response to Growth Factors in Bovine Cartilage Explants
Background/Purpose: Mechanical loading of cartilage is an essential part of the function and maintenance of the joint. Despite the apparent importance of continuous mechanical loading,…Abstract Number: 0355 • ACR Convergence 2020
Collagen Turnover Markers Are Associated with Active Psoriatic Arthritis and Decrease with Guselkumab Treatment in a Phase-3 Clinical Trial
Background/Purpose: Guselkumab (GUS), an interleukin-23p19-subunit monoclonal antibody, demonstrated efficacy compared to placebo (PBO) in reducing skin and musculoskeletal signs and symptoms in patients with active…Abstract Number: 0424 • ACR Convergence 2020
Anti-Collagen II Antibodies in Patients with Relapsing Polychondritis
Background/Purpose: Relapsing polychondritis (RP) is a highly heterogenous systemic inflammatory disorder that affects many organ systems, in particular, cartilaginous structures. Clinical presentations in RP are…Abstract Number: 1106 • ACR Convergence 2020
MMP Mediated Type I Collagen Degradation Is Associated with Erosive Hand Osteoarthritis in a Hospital-based Observational Cohort – the NOR-HAND Study
Background/Purpose: Hand osteoarthritis (OA) is a common degenerative joint disease affecting mainly the interphalangeal and first carpometacarpal joints. The disease manifests as inflammation and deterioration…Abstract Number: 1108 • ACR Convergence 2020
Cartilage Biomarkers s-Coll2-1 and s-Coll2-1NO2 Are Associated with Knee Osteoarthritis MRI Features and Predict Disease Worsening
Background/Purpose: To identify if biochemical markers s-Coll2-1, a peptide of type collagen and its nitrated from, s-Coll2-1NO2 are associated to knee osteoarthritis (OA), focusing on…
