Associations of Serum Anti-Malondialdehyde-Acetaldehyde (MAA) Antibodies with Cardiovascular and Respiratory Mortality in Men with Rheumatoid Arthritis
Background/Purpose: Mortality from cardiovascular (CV) and respiratory causes is increased in rheumatoid arthritis (RA). Predictive serologic biomarkers of these events are lacking. Previously, we have…Abstract Number: 1916 • 2015 ACR/ARHP Annual Meeting
Validation of Novel Biomarker Candidates for Systemic Sclerosis
Background/Purpose: Systemic sclerosis (SSc) is a systemic autoimmune disease that manifests as progressive fibrosis of the skin and internal organs. SSc is associated with the…Abstract Number: 2463 • 2015 ACR/ARHP Annual Meeting
Soluble Low-Density Lipoprotein Receptor-Related Protein 1 in Juvenile Idiopathic Arthritis
Background/Purpose: Low-density lipoprotein receptor–related protein 1 (LRP1), a transmembrane protein, mediates endocytosis of an array of extracellular ligands. LRP1 has intracellular and extracellular domains. With…Abstract Number: 2834 • 2015 ACR/ARHP Annual Meeting
CXCL10 Expression Is Elevated in Synovial Fluid of Psoriatic Arthritis Patients
Background/Purpose: Psoriatic arthritis (PsA), an inflammatory musculoskeletal disease, develops in approximately 30% of patients with psoriasis. We previously identified C-X-C motif chemokine 10 (CXCL10) as…Abstract Number: 168 • 2015 ACR/ARHP Annual Meeting
Ultrasound Evaluation of the Efficacy of Biologic and Targeted Synthetic Dmards Toward Rheumatoid Arthritis Patients: Kyushu Multicenter Rheumatoid Arthritis Ultrasound Prospective Observational Cohort in Japan
Background/Purpose: Few prospective ultrasound (US) cohort studies of rheumatoid arthritis (RA) patients treated by biologic or targeted synthetic DMARDs (b/tsDMARDs) are reported. We have been…Abstract Number: 574 • 2015 ACR/ARHP Annual Meeting
Metabolomic Profiling Predicts Outcome of Rituximab Therapy in Rheumatoid Arthritis
Background/Purpose: We hypothesized that characterization of patients’ metabolic profiles, utilizing both high-resolution 1H-nuclear magnetic resonance (NMR) and mass spectrometry (MS), might help predict response to…Abstract Number: 1021 • 2015 ACR/ARHP Annual Meeting
Nucleic Acids Sensing Receptors RIG-I and MDA5 As Potential Amplifiers of the Interferon Signature in Childhood Onset Systemic Lupus Erythematosus
Background/Purpose: Defective or sustained activation of Interferon (IFN) signaling has been associated with enhanced susceptibility to systemic lupus erythematosus (SLE). The cytosolic RIG-I-like receptors (RLRs),…Abstract Number: 1575 • 2015 ACR/ARHP Annual Meeting
Serum Vascular Cell Adhesion Molecule-1 (VCAM-1) Levels Are Associated with Vascular Dysfunction and Increased Cardiovascular Risk in an Animal Model and Patients with Rheumatoid Arthritis
Background/Purpose: Mortality is increased in Rheumatoid arthritis (RA) patients mainly due to cardiovascular (CV) disease; however the biologic mechanisms are unknown. Increased CV risk in…Abstract Number: 1917 • 2015 ACR/ARHP Annual Meeting
Developing and Validating a Serum Biomarker for the Extent of Skin Disease in Patients with Diffuse Cutaneous Systemic Sclerosis
Background/Purpose: In this study we aimed to both agonistically investigate alterations in the serum proteome of patients with diffuse cutaneous systemic sclerosis (dcSSc), as well…Abstract Number: 2584 • 2015 ACR/ARHP Annual Meeting
Prediction of Disease Relapses By Multi-Biomarker Disease Test Activity in Rheumatoid Arthritis Patients Tapering DMARD Treatment
Background/Purpose: To analyze the role of multi-biomarker disease activity (MBDA) in predicting disease relapses in rheumatoid arthritis (RA) patients in sustained remission, tapering disease modifying…Abstract Number: 2965 • 2015 ACR/ARHP Annual Meeting
Might Troponin be a Marker for Subclinical Scleroderma Heart Involvement (SHI)?
Background/Purpose: Systemic sclerosis (SSc) is a rare connective tissue disease with pronounced alterations of the microvascular system, frequent cellular and humoral immunity abnormalities and fibroblast…Abstract Number: 171 • 2015 ACR/ARHP Annual Meeting
Serum Calprotectin Levels Correlate with Ultrasonographic Synovitis in Rheumatoid Arthritis Patients
Background/Purpose: Calprotectin (S100A8/9, MRP8/14) has been demonstrated as a promising biomarker of clinical and laboratory disease activity in rheumatoid arthritis (RA). In addition, two small…Abstract Number: 583 • 2015 ACR/ARHP Annual Meeting
A Serological Biomarker of Active MMP3, but Total MMP3, Can Early Assess Treatment Efficacy and Differentiate Doses of Tocilizumab and an Early Change in Active MMP3, but Not Total MMP3, Is Associated with Radiographic Change at 1 Year
Background/Purpose: Protease activity, especially MMP3, is known to be increased with arthritis, such as rheumatoid arthritis. MMP3 is mainly expressed by fibroblasts; a key cell…
