Which ASDAS-ESR Cut-offs for Disease Activity Correspond to ASDAS-CRP Cut-offs in Axial Spondyloarthritis? – Results from the EuroSpA Collaboration
Background/Purpose: When assessing disease activity in patients with axial spondyloarthritis (axSpA), the Ankylosing Spondylitis Disease Activity Score with C-reactive protein (ASDAS-CRP) is recommended over ASDAS…Abstract Number: 1989 • ACR Convergence 2023
Shared Variation Among Cartilage Thickness Change Maps and Baseline Clinical Features at the Initiation of Structural Knee Osteoarthritis
Background/Purpose: To identify features of cartilage thickness change and baseline clinical indicators associated with the transition from normal to mildly reduced joint space as an…Abstract Number: 2213 • ACR Convergence 2023
Identification of a Diagnostic Model for Axial Spondyloarthritis in Daily Clinical Practice Using a Random Forest Machine Learning Approach
Background/Purpose: In axial spondyloarthritis (axSpA), early diagnosis plays a key role in preventing disease progression. However, a validated diagnostic algorithm does not exist, while classification…Abstract Number: 0450 • ACR Convergence 2022
Incidence of Solid and Hematologic Tumors in Patients with ANCA: A 10-year Retrospective Cohort Study
Background/Purpose: Serum antineutrophil cytoplasmic antibodies (ANCA) are significantly associated with the development of ANCA-associated vasculitides (AAV) but may also be detected in patients with other…Abstract Number: 0552 • ACR Convergence 2022
Identifying Subgroups of Patients Undergoing Knee Replacement
Background/Purpose: Knee replacement surgery (KR) is prevalent in the US with estimated lifetime risk from age 25 of 7% for males and 9.5% for females,…Abstract Number: 0643 • ACR Convergence 2022
Subsetting SLE Patients Based on DNA Methylation at the Time of Disease Flare
Background/Purpose: Current treatments for SLE do not adequately prevent disease progression. This lack of efficacy, in part, relates to the molecular heterogeneity of disease. The…Abstract Number: 0768 • ACR Convergence 2022
Reevaluating Clinical Outcomes of Patients on Combination Biologics
Background/Purpose: Biologic treatments such as monoclonal antibodies have become first line treatment for many autoimmune diseases and now monoclonal antibodies are being used to treated…Abstract Number: 0870 • ACR Convergence 2022
Knee Acoustic Emissions as a Noninvasive Biomarker of Articular Health in Juvenile Idiopathic Arthritis
Background/Purpose: Juvenile idiopathic arthritis (JIA) refers to all forms of autoimmune arthritis in children with undetermined etiology, and thus it is the most prevalent chronic…Abstract Number: 1317 • ACR Convergence 2022
The Epidemiology of Old versus Young Males Referred for BMD Assessment
Background/Purpose: Data on osteoporosis in men are scarce. The World Health Organisation's (WHO) definition of a T-score less than 2.5 has only been described for…Abstract Number: 1606 • ACR Convergence 2022
An Expanded Anti-citrullinated Protein Antibody Profile Derived Using Unsupervised Machine Learning Predicts Treatment Responses to Biologic Therapies in Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) treatments have advanced with the availability of biologic therapies. Despite these advances, 30-40% of patients receiving a biologic do not adequately…
