Accurate Identification of ANCA-Associated Vasculitis Cases from Clinical Notes Using Machine Learning
Background/Purpose: ANCA-associated vasculitis (AAV) is a rare disease associated with substantial morbidity and mortality.1 To enable outcomes and comparative effectiveness studies using large, phenotypically diverse…Abstract Number: 1087 • ACR Convergence 2022
Identification of Novel Proteomic Biomarkers of Disease Activity in ANCA-Associated Vasculitis Using a High Throughput Approach
Background/Purpose: ANCA-associated vasculitis (AAV) is associated with excess morbidity and mortality. Identifying novel biomarkers may reveal new therapeutic targets and clinically useful biomarkers of disease…Abstract Number: 1091 • ACR Convergence 2022
IgG Antibody Subclass Glycan Modifications in Patients with ANCA-Associated Vasculitis in Active vs Remission States – a Proof-of-Concept Study
Background/Purpose: The Fc portion of IgG tends to be hypogalactosylated among patients with ANCA-associated vasculitis (AAV) compared with healthy controls1,2,3. Glycan modifications may affect antibody…Abstract Number: 1654 • ACR Convergence 2022
Hydroxychloroquine Dosing Less Than 5 Mg/kg/day Leads to Increased Hospitalizations for Systemic Lupus Erythematosus Flares
Background/Purpose: Hydroxychloroquine (HCQ) is the backbone of SLE therapy, due to its benefits on increasing survival and decreasing lupus flares. In 2011, ophthalmology guidelines recommended…Abstract Number: 0418 • ACR Convergence 2021
Longitudinal Patterns of Renal Function in ANCA-Associated Vasculitis
Background/Purpose: Renal involvement is common in ANCA-associated vasculitis (AAV). Prior analyses show that end stage renal disease (ESRD) in AAV may be multifactorial. Little is…Abstract Number: 0787 • ACR Convergence 2021
Association of Hemoglobin Levels and Radiographic Progression in the BRASS Registry
Background/Purpose: To evaluate baseline hemoglobin (Hb) and radiographic progression over time for patients in the Brigham and Women’s Hospital Rheumatoid Arthritis Sequential Study (BRASS) registry.Methods:…Abstract Number: 1103 • ACR Convergence 2021
Disease Associations with Very High Serum IgG4 Concentrations: A Retrospective Multi-Center Study
Background/Purpose: Serum IgG4 concentrations are used as part of the evaluation for suspected IgG4-related disease (IgG4-RD), but the specificity of this test, especially at very…Abstract Number: 1262 • ACR Convergence 2021
Fish Oil Supplementation and Pro-inflammatory and Pro-Resolving Lipid Mediators in Patients with and Without Systemic Lupus Erythematosus
Background/Purpose: Omega-3 fatty acid-derived “specialized pro-resolving mediators” (SPM) are low-abundance lipid mediators (LM) central to inflammation resolution. In this cross-sectional study, we investigated whether fish…Abstract Number: 1414 • ACR Convergence 2021
The Current State of Expedited Referral Systems Incorporating Vasculitis Ultrasound for the Diagnosis of Giant Cell Arteritis in Rheumatology Practices in the United States
Background/Purpose: Expedited referral systems or “fast-track” clinics incorporating vasculitis ultrasound (VUS) into the evaluation of patients with suspected giant cell arteritis (GCA) have shown reduced…Abstract Number: 0545 • ACR Convergence 2020
The Use of Tocilizumab and Tofacitinib in Patients with Resolved Hepatitis B Infection: A Case Series
Background/Purpose: The use of immunosuppressive medications in patients with a history of hepatitis B virus (HBV) infection is associated with an increased risk of HBV…Abstract Number: 0756 • ACR Convergence 2020
Increased Risk of Hospitalization in Patients with RA Who Are ACPA Positive and Shared Epitope Positive
Background/Purpose: A strong genetic association between HLA-DRB1 alleles containing the shared epitope (SE) and RA has been described.1 The SE has been associated with ACPA…Abstract Number: 1051 • ACR Convergence 2020
Rituximab for Interstitial Pneumonia with Autoimmune Features at Two Academic Medical Centers
Background/Purpose: Many patients with interstitial lung disease (ILD) have autoimmune features without a distinct rheumatic disease and are thus designated as having interstitial pneumonia with…Abstract Number: 1620 • ACR Convergence 2020
Hepatitis B Screening Practices When Prescribing Tocilizumab or Tofacitinib in Real World Practice
Background/Purpose: Hepatitis B virus (HBV) reactivation can complicate treatment with immunosuppressive medications. Reactivation risk varies by the status of HBV infection but has been reported…Abstract Number: 183 • 2019 ACR/ARP Annual Meeting
Exploring Heterogeneity in Rheumatoid Arthritis: Patient Profiling Through Principal Component and Cluster Analysis of the BRASS Registry
Background/Purpose: Data-driven principal component (PC) and cluster analysis has the potential to identify previously unknown patient subgroups within a rheumatoid arthritis (RA) registry to establish…
