Background/Purpose: Postural Orthostatic Tachycardia Syndrome (POTS) is a dysautonomia associated with chronic autonomic and neuropathic symptoms, including pain in multiple body regions, paresthesia, fatigue, brain…Abstract Number: 0659 • ACR Convergence 2022
Comprehensive Proteomic Screen of Murine Lupus Serum and Cerebrospinal Fluid Uncovers Diagnostic and Therapeutic Targets
Background/Purpose: Up to 50% of SLE patients experience neuropsychiatric involvement (neuropsychiatric lupus, or NPLSE) through an unknown mechanism. Diagnosis currently relies on clinical criteria and…Abstract Number: 1151 • ACR Convergence 2022
Colonic Organoids to Study the Role of HLA-B27 in Gastrointestinal Epithelial Biology
Background/Purpose: Axial spondyloarthritis (axSpA) is defined clinically as inflammatory back pain along with peripheral arthritis, and extra-articular manifestations involving the eye, gut, and skin. Even…Abstract Number: 1610 • ACR Convergence 2022
Are Serological Protease-mediated Peptides of Tissue Remodeling and Inflammation the New Disease Activity Biomarkers in Psoriatic Arthritis Patients?
Background/Purpose: Inflammatory and degenerative processes in the joint tissues are hallmarks of patients with psoriatic arthritis (PsA). Here, proteases play a major role in remodeling…Abstract Number: 1833 • ACR Convergence 2022
Intraarticular Morphine in Knee-arthritis – Results of a Randomized Placebo-controlled Trial
Background/Purpose: The current standard of intraarticular therapy in patients with inflammatory arthritis (e.g. rheumatoid arthritis; RA) or inflammatory exacerbations of osteoarthritis (OA) is the injection…Abstract Number: 2143 • ACR Convergence 2022
Effect of Upadacitinib and Adalimumab on Residual Pain Among Patients with Psoriatic Arthritis Whose Inflammation Was Attenuated After Three and Six Months of Treatment
Background/Purpose: Managing pain, a predominant symptom of psoriatic arthritis (PsA), is a priority for patients and healthcare providers. Upadacitinib (UPA), a Janus kinase (JAK) inhibitor,…Abstract Number: 0133 • ACR Convergence 2022
Retention Rate of Targeted Therapies in Erdheim-Chester Disease
Background/Purpose: Erdheim-Chester disease (ECD) is a rare non-Langerhans histiocytosis with a broad clinical spectrum. The therapeutic landscape of ECD has remarkably changed over the last…Abstract Number: 0557 • ACR Convergence 2022
VEXAS Syndrome Is Characterized by Blood and Tissues Inflammasome Pathway Activation and Monocyte Dysregulation
Background/Purpose: Acquired mutations in the UBA1 gene, occurring in myeloid cells and resulting in expression of a catalytically impaired isoform of the enzyme E1, were…Abstract Number: 0693 • ACR Convergence 2022
Low Neutrophil Ectonucleotidase Activity Drives Neutrophil-Platelet Aggregation and Platelet Activation in Antiphospholipid Syndrome (APS)
Background/Purpose: By converting extracellular ATP into homeostatic adenosine, the ectonucleotidases CD39 (ATP to AMP) and CD73 (AMP to adenosine) dictate extracellular purinergic gradients and as…Abstract Number: 1154 • ACR Convergence 2022
Axial Spondyloarthritis: Profiling of MiRNAs in Peripheral Blood Mononuclear Cells
Background/Purpose: microRNAs (miRNAs) are small non-coding RNAs, which are essential for correct gene expression. The dysregulation in miRNA expression is accompanied by various diseases and…Abstract Number: 1614 • ACR Convergence 2022
Females with Non-Radiographic but Not with Radiographic Axial Spondyloarthritis Are Less Likely to Achieve Inactive Disease State Than Males: Results from a Multicountry Prospective Observational Study
Background/Purpose: Emerging evidence suggests that men and women experience axial spondyloarthritis (axSpA) differently. Some studies suggested that the probability of treatment response was lower in…Abstract Number: 1846 • ACR Convergence 2022
Cardiac Sarcoidosis: An Underdiagnosed, Life-threatening yet Treatable Disease
Background/Purpose: Cardiac sarcoidosis (CS) is potentially life-threatening and it typically causes heart failure, ventricular arrhythmia, AV block or sudden death. CS has been reported to…Abstract Number: 2161 • ACR Convergence 2022
Alterations of Nutritional Status of Scleroderma Patients and Associations with Disease-specific Features
Background/Purpose: Systemic sclerosis (SSc) is characterized by skin and organ involvement and chronic disease course. In particular, involvement of the gastrointestinal tract and systemic inflammation…Abstract Number: 0137 • ACR Convergence 2022
Polyarticular Arthritis and Osteolysis Caused by Mutations in the ASAH1 Gene: Farber Disease Clinical Presentations in the First-ever Natural History Study
Background/Purpose: Farber disease is frequently misdiagnosed as polyarticular juvenile idiopathic arthritis or seronegative rheumatoid arthritis which leads to a delay in diagnosis for many patients.…
