Metabolomics Identifies Early Mechanisms of Atherogenic Dyslipidaemia in Juvenile-SLE Patients Associated with Inflammation
Background/Purpose: Cardiovascular disease (CVD) is a leading cause of mortality in patients with juvenile-onset systemic lupus erythematosus (JSLE) through atherosclerosis, the build-up of lipids and…Abstract Number: 0027 • ACR Convergence 2021
Metabolomic Study of Rheumatoid Arthritis Using 1H Nuclear Magnetic Resonance (1H NMR)
Background/Purpose: Rheumatoid arthritis (RA) remains a disease with high morbidity. Biologic agents revolutionized the therapy of RA, but they are withdrawn in 50% of patients…Abstract Number: 0559 • ACR Convergence 2021
Targeting NNMT as a Novel Metabolic Approach to Treat Systemic Sclerosis
Background/Purpose: Fibrosis, the hallmark of systemic sclerosis (SSc), is associated with metabolic and epigenetic alterations that are incompletely characterized. Our laboratory had previously implicated dysregulated…Abstract Number: 0590 • ACR Convergence 2021
Association of Lipid Mediator Profiles and Development of Future Incident Inflammatory Arthritis in a High Risk, Anti-citrullinated Protein Antibody Positive Population
Background/Purpose: Lipid mediators are endogenously derived from the metabolism of omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) and have important roles in promoting and resolving…Abstract Number: 0680 • ACR Convergence 2020
Sustained Treat to Target Uric Acid Lowering Therapy Markedly Lowers Fatty Acids Levels in Gout Patients
Background/Purpose: Though hyperuricemia is implicated in cardiovascular disease, the metabolic syndrome, and type 2 diabetes in both gout and in asymptomatic patients, the core metabolism…Abstract Number: 0747 • ACR Convergence 2020
Isotope-Labeling-LC-MS-based Metabolic Profiling of Multiple Serum Sample Sets for the Discovery of High-confidence Rheumatoid Arthritis Biomarkers
Background/Purpose: Early diagnosis of rheumatoid arthritis (RA) is hampered by suboptimal accuracy of currently available serological biomarkers. In this work, we applied a high-performance chemical…Abstract Number: 0842 • ACR Convergence 2020
mTOR Signaling Pathway Blockade and Rab4 Expression Affects Metabolism of Lupus T Cells
Background/Purpose: Pro-inflammatory T-cell development underlies the pathogenesis of systemic lupus erythematosus (SLE). Activation of the mechanistic target of rapamycin (mTOR) plays a central role in…Abstract Number: 0844 • ACR Convergence 2020
Rab4A Regulates Glomerulonephritis and Tryptophan Metabolism in Sle1.2.3. Lupus-prone Mice via Recycling of CD98
Background/Purpose: Systemic Lupus Erythematosus (SLE) is an autoimmune disease with an incompletely understood etiology. Previous work has identified Rab4A, a small GTPase responsible for endosomal…Abstract Number: 0970 • ACR Convergence 2020
Oxylipins Profiles During the Earliest Phases of Rheumatoid Arthritis: Associations with Clinical Stage and Treatment Outcomes
Background/Purpose: Altered eicosanoids have been linked to rheumatoid arthritis (RA), suggesting an enhanced metabolization. Eicosanoid metabolism forms a complex network, involving different pathways and mediators,…Abstract Number: 0991 • ACR Convergence 2020
Pathogenic, Glycolytic PD-1+ B Cells Accumulate in the Hypoxic RA Joint
Background/Purpose: Rheumatoid arthritis (RA) often has a progressive and debilitating course, with significant impact on the patient’s quality of life. Despite the long-known association with…Abstract Number: 0996 • ACR Convergence 2020
Bacteria-Derived Indole Drives Autoimmune Arthritis by Altering B Cell Glycosylation of Autoantibodies
Background/Purpose: Background: Dysbiosis of gut bacterial communities in rheumatoid arthritis (RA) is a noted phenomenon in both murine models and human patients; however, the mechanisms…Abstract Number: 1008 • ACR Convergence 2020
Assessing Improved Risk Prediction of Seropositive Rheumatoid Arthritis by Environmental, Genetic, and Preclinical Plasma Metabolite Factors
Background/Purpose: Recent research has advanced the understanding of associations between environmental, genetic, and metabolic factors and rheumatoid arthritis (RA), introducing potential to improve risk prediction.…Abstract Number: 1092 • ACR Convergence 2020
NMR-Based Serum Metabolomics, Is It Different in Clinico-Serological Clusters of Idiopathic Inflammatory Myositis?
Background/Purpose: Idiopathic inflammatory myositis (IIM) are rare and heterogenous. Myositis specific antibodies (MSA) show mutual exclusivity and identify specific clinical phenotypes1. Most biomarker studies are…Abstract Number: 1221 • ACR Convergence 2020
Evaluation of Methotrexate Efficacy and Exploration of Metabolites Associated with Disease Activity in Collagen-induced Arthritis Mouse Model
Background/Purpose: Methotrexate (MTX) is cornerstone of therapy for rheumatoid arthritis. However, response to MTX is variable and unpredictable among patients. Therefore, there is a critical…Abstract Number: 1517 • ACR Convergence 2020
Metabolic Regulation of Type 3 Innate Lymphoid Cells by Intestinal Bacteria-Derived Indoles in Ankylosing Spondylitis
Background/Purpose: Intestinal microbial dysbiosis, intestinal inflammation, and Th17 immunity are all linked to the pathophysiology of ankylosing spondylitis (AS); however, the mechanisms linking them remain…
