Abstract Number: 1315 • ACR Convergence 2025
High-resolution thermography and Artificial Intelligence to evaluate and classify Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) is an autoimmune polyarthritis that typically affects the small joints of the hands and feet. While imaging modalities such as ultrasound…Abstract Number: 0845 • ACR Convergence 2025
Machine Learning–Based Skin Transcriptome Classifier (v2.0) Links SSc Molecular Subtypes to Disease Severity and Progression
Background/Purpose: Systemic Sclerosis (SSc) is a clinically and molecularly heterogeneous autoimmune disease. We identified five intrinsic molecular subtypes in SSc by applying semi-supervised machine learning…Abstract Number: 0019 • ACR Convergence 2025
Single cell characterization of the circulating immune system in Sjögren’s Syndrome
Background/Purpose: Sjögren’s syndrome (SS) is a chronic autoimmune disease characterized by the infiltration of circulating immune cells into the salivary and lacrimal glands. The properties…Abstract Number: 1309 • ACR Convergence 2025
Transcriptomic biomarkers of progression from undifferentiated arthritis to rheumatoid arthritis
Background/Purpose: A broad range (6-55%) of patients classified as having undifferentiated arthritis (UA) tend to progress to rheumatoid arthritis (RA), suggesting that UA in these…Abstract Number: 0808 • ACR Convergence 2025
Spatial Transcriptomics Show Fibroblast LIF Receptor Drives Fibrosis in Systemic Sclerosis
Background/Purpose: Systemic sclerosis (SSc) is an autoimmune, fibroinflammatory disease of skin and visceral organs. Current SSc therapies have limited efficacy for progressive fibrosis. Our prior…Abstract Number: 2114 • ACR Convergence 2025
Development of a Fracture Prediction Model for Patients Aging with HIV
Background/Purpose: Fragility fractures are a critical outcome for people ageing with HIV (PAH). Studies demonstrate higher prevalence, incidence, and earlier onset than for the general…Abstract Number: 2666 • ACR Convergence 2025
Rare TNFAIP3 Hypomorphic Variants are a Massively Underestimated Driver of Human Autoinflammatory Disease
Background/Purpose: TNFAIP3 encodes the ubiquitin editing enzyme A20, which inhibits multiple proinflammatory signaling pathways. Heterozygous germline mutations in TNFAIP3 cause the autoinflammatory disease Haploinsufficiency of…Abstract Number: 1303 • ACR Convergence 2025
Impact of Fruits and Vegetables Intake on Immune-mediated Inflammatory Diseases:a Two-sample Mendelian Randomization Study
Background/Purpose: A balanced diet can prevent diseases and promote physical and mental health. Accumulating evidence shows that fruits and vegetables (F&Vs) intake is associated with…Abstract Number: 0797 • ACR Convergence 2025
Spatial transcriptomics identifies density-sensing fibroblasts in synovial lining
Background/Purpose: The synovial lining is crucial for joint homeostasis, forming a barrier and producing lubricants through specialized fibroblasts. These fibroblasts differ from sublining fibroblasts, which…Abstract Number: 2639 • ACR Convergence 2025
Gut Microbiome Signatures Forecast Clinical Response to Methotrexate in Treatment-Naïve Early Rheumatoid Arthritis
Background/Purpose: Oral methotrexate (MTX) is the cornerstone treatment for newly diagnosed rheumatoid arthritis (RA), yet up to 50% of patients do not respond adequately. Early…Abstract Number: 1210 • ACR Convergence 2025
Artificial Intelligence-Based Capillaroscopy and Laboratory Biomarkers to Predict Disease Activity in Idiopathic Inflammatory Myopathies: Preliminary Data from the CapIAMI Cohort
Background/Purpose: Nailfold videocapillaroscopy (NVC) is a valuable non-invasive tool for assessing microvascular damage in autoimmune diseases. However, its application in idiopathic inflammatory myopathies (IIM) remains…Abstract Number: 0504 • ACR Convergence 2025
Spatial profiling of gene signatures in synovial tissue informs treatment strategy for Rheumatoid Arthritis
Background/Purpose: Rheumatoid arthritis (RA) shows heterogeneous therapeutic responses that may reflect diversity within synovial tissue (ST). We aimed to identify gene signatures that predict Adalimumab…Abstract Number: 2601 • ACR Convergence 2025
Characterisation of immunometabolic reprogramming at the single cell level in patients with systemic lupus erythematosus and preclinical autoimmunity
Background/Purpose: Systemic lupus erythematosus (SLE) is characterised by innate immune activation and autoantibodies against nucleic self-antigens. The metabolic state of immune cells is emerging as…Abstract Number: 1168 • ACR Convergence 2025
Interstitial Lung Disease-Associated Antibody Testing and Positivity Rates in Systemic Autoimmune Rheumatic Diseases from a National Reference Laboratory
Background/Purpose: Interstitial lung disease (ILD) is frequent in systemic autoimmune rheumatic diseases (SARDs) and is associated with poor prognosis. The prevalence of ILD is approximately…Abstract Number: 0329 • ACR Convergence 2025
Machine Learning-Based Model to Predict Rapid Structural Progression in Knee Osteoarthritis
Background/Purpose: Osteoarthritis (OA) is the most common chronic joint disorder, characterized by structural cartilage and bone damage that often causes pain and disability. However, the…
