The Novel Anti-BICD2 Autoantibody Potentially Predicts a Favorable Disease Course in SSc
Background/Purpose: To evaluate clinical associations of our recently discovered systemic sclerosis-specific auto-antigen BICD2 in clinically well characterized systemic sclerosis (SSc) cohorts from two tertiary referral…Abstract Number: 1941 • 2016 ACR/ARHP Annual Meeting
Retrospective Survey of Concomitant Autoimmune Diseases and Autoantibodies in a Cohort of Patients with ANCA-Associated Vasculitis (AAV)
Background/Purpose: Anti-neutrophil cytoplasmic antibodies (ANCA) associated vasculitis (AAV) - granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA) have heterogenous clinic…Abstract Number: 2871 • 2016 ACR/ARHP Annual Meeting
Unaffected Lupus Relatives Are Distinguished from SLE Patients and Unaffected Individuals Not Related to SLE Patients By Lupus-Specific Connective Tissue Disease Questionnaire Scores, Autoantibodies, and Distinct Soluble Mediators
Background/Purpose: Identifying populations at risk of SLE is essential to curtail inflammatory damage and select individuals for prevention trials. Blood relatives (Rel) of lupus patients…Abstract Number: 2 • 2016 ACR/ARHP Annual Meeting
Rheumatoid Arthritis (RA)-Related Autoimmunity and Lumbar Bone Mineral Density in a Multi-Ethnic Community-Dwelling Population
Background/Purpose: Previous studies suggest that antibodies to citrullinated protein antigens (ACPA) contribute to decreased hand bone mineral density (BMD) in RA-free individuals. No evidence exists…Abstract Number: 853 • 2016 ACR/ARHP Annual Meeting
Clinical Associations of Anti-Eukaryotic Initiation Factor 2B (anti-eIF2B) Antibodies in a Large Cohort of Patients with Anti-Nuclear Antibody Negative Systemic Sclerosis
Background/Purpose: Autoantibodies can be characterized in up to 95% of patients with systemic sclerosis (SSc) and provide enormous diagnostic and prognostic value in the clinical…Abstract Number: 2112 • 2016 ACR/ARHP Annual Meeting
Disease-Activity Associated Autoantibodies to Malondialdehyde-Modified Proteins Can be Isolated from Synovial B Cells in RA
Background/Purpose: Malondialdehyde (MDA) is a naturally occurring reactive aldehyde that arises during apoptosis or as a consequence of elevated reactive oxygen species and lipid peroxidation.…Abstract Number: 2914 • 2016 ACR/ARHP Annual Meeting
Association of Radiographic Findings in Hand X-Ray with Autoantibodies in Patients with Systemic Sclerosis
Background/Purpose: Musculoskeletal involvement is a major complication for patients with systemic sclerosis (SSc). Various radiographic abnormalities are observed, especially in hands, however, the detailed prevalence…Abstract Number: 163 • 2016 ACR/ARHP Annual Meeting
Fluorescence Optical Imaging Reveals Distinct Patterns of Hand Joint Inflammation in Seropositive and Seronegative Early Rheumatoid Arthritis
