Anti- Citrullinated Protein Antibodies but Not Rheumatoid Factor Are Associated with Larger Bone Erosions in rheumatoid arthritis patients- a Cross-Sectional Micro Computed Tomography Study
Background/Purpose: Anti- citrullinated protein antibodies (ACPA) are known to be associated with joint destruction and a more severe disease course in rheumatoid arthritis (RA) patients.…Abstract Number: 1938 • 2012 ACR/ARHP Annual Meeting
A New Enzyme-Linked Immunosorbent Assay System for Detecting Autoantibodies to Aminoacyl-tRNA Synthetases: Clinical Usefulness in Myositis and Interstitial Pneumonia
Background/Purpose: Autoantibodies to aminoacyl-tRNA synthetases (ARS) are the most frequent myositis-specific antibodies and they are useful in the diagnosis and management of polymyositis (PM)/ dermatomyositis…Abstract Number: 1122 • 2012 ACR/ARHP Annual Meeting
Identifying Radiographic Phenotypes of Early Knee Osteoarthritis Using Separate Quantitative Features Might Improve Patient Selection for More Targeted Treatment
Background/Purpose: Osteoarthritis (OA) is a degenerative joint disease characterized by pain and functional disability. The expression of OA varies significantly between individuals and over time,…Abstract Number: 710 • 2012 ACR/ARHP Annual Meeting
Optical Density Measure of the Papillary Dermis Discriminates As Abnormal Clinically Uninvolved Skin in Systemic Sclerosis and Correlates with Severity of Skin Thickness
Background/Purpose: Skin involvement in systemic sclerosis (SSc) is often primary outcome in clinical trials and its severity inversely correlates with prognosis. Nevertheless, an objective quantitative…Abstract Number: 305 • 2012 ACR/ARHP Annual Meeting
Clinicopathologic Correlates for Activity and Damage of Lupus Nephritis in Childhood-Onset Systemic Lupus Erythematosus
Background/Purpose: High AI activity (AI), tubulointerstitial (TI), and chronicity index (CI) scores from renal biopsy may predict poor renal outcomes in lupus nephritis (LN)…Abstract Number: 2532 • 2012 ACR/ARHP Annual Meeting
Whole Transcriptome Analysis in Relapsing Polychondritis: A Single-Center Analysis of 35 Patients
