Serum Interferon Score Is a Biomarker of Active Disease in Patients with Early Diffuse Cutaneous Systemic Sclerosis Enrolled in the Prospective Registry of Early Systemic Sclerosis (PRESS) Cohort
Background/Purpose: Several published studies have demonstrated activation of the interferon type 1 (IFN) pathway in sera from patients with systemic sclerosis (SSc). Specifically, levels of…Abstract Number: 0037 • ACR Convergence 2021
Identification and Validation of Four Circulating Autoantibodies Associated with the ACPA Status in Early Rheumatoid Arthritis
Background/Purpose: The presence of anti-citrullinated protein antibodies (ACPAs) is a highly specific hallmark of rheumatoid arthritis (RA), that is present also in early disease. However,…Abstract Number: 0029 • ACR Convergence 2020
Urine Proteomic Classifiers Predict Renal Histological Activity and Chronicity Indices and May Predict Treatment Response in Lupus Nephritis
Background/Purpose: Current management of lupus nephritis (LN) is guided by histopathological features on kidney biopsy and measurement of proteinuria. Urine proteomics is a non-invasive source…Abstract Number: 0038 • ACR Convergence 2020

Serum Proteomics Implicates Neutrophil Degranulation in Rheumatoid Arthritis Disease Activity
Background/Purpose: Though targeted therapeutics have improved outcomes in Rheumatoid Arthritis (RA) treatment, the understanding of the underlying biological mechanisms that mediate inflammatory arthritis in RA…Abstract Number: 0763 • ACR Convergence 2020
Plasmatic Proteome in Individuals with Arthralgia at Risk of Developing Rheumatoid Arthritis
Background/Purpose: The presence of antibodies against citrullinated proteins (ACPA) significantly increases the risk of developing rheumatoid arthritis (RA). EULAR characterised individuals with arthralgia suspicious for…Abstract Number: 0936 • ACR Convergence 2020
Urine Proteomics and Single Cell Transcriptomics Identify IL-16 as a Biomarker for Lupus Nephritis
Background/Purpose: Treatment of lupus nephritis relies on renal histopathological features. However, renal biopsies do not capture patient-specific active biological pathways. Urine proteomic biomarkers could revolutionize…Abstract Number: 0953 • ACR Convergence 2020
Long-term Xanthine Oxidase Inhibitor Treat to Target Urate Lowering Therapy Coordinately Re-wires the Mononuclear Leukocyte Mitochondrial and Inflammatory Proteome in Gout
Background/Purpose: In gout, long-term xanthine oxidase inhibitor treat to target urate lowering therapy (XOIT2T) markedly reduces flares and synovitis, despite delayed resolution of tissue crystal…Abstract Number: 1359 • ACR Convergence 2020
Targeted Serum Proteomic Analysis Following Upadacitinib Treatment in Ankylosing Spondylitis Shows Robust Suppression of Innate and Adaptive Immune Pathways with Tissue Repair Modulation
