Changing Osteoarthritis Treatment Assessment Paradigms: Subchondral Bone Is a More Responsive Measure of Progression Than the Current Radiographic Standard
Background/Purpose: Radiographic joint space width (JSW) assessment, a surrogate for cartilage assessment, is the standard for structure modification trials of osteoarthritis (OA). However the subchondral…Abstract Number: 995 • 2012 ACR/ARHP Annual Meeting
Genetic Effects of HLA-DRB1, IL4R, and FcγRIIb On Long-Term Treatment Responses in Patients with Early Rheumatoid Arthritis: 78-Week Results of a Phase 4 Study
Background/Purpose: Previous analyses suggested that the HLA-DRB1 shared epitope (SE), and the IL4R V50I and the FcγRIIb I232T single nucleotide polymorphisms (SNPs) affected response to…Abstract Number: 996 • 2012 ACR/ARHP Annual Meeting
Genetic Predictors of Methotrexate Efficacy and Toxicity in Early Rheumatoid Arthritis: Results From the Treatment of Early Aggressive Rheumatoid Arthritis Trial

CNstream2: Improved SNP and CNV Genotyping Reveals New Loci Associated with Rheumatic Diseases
Background/Purpose: In Genome-Wide Association Studies (GWAS), the performance of the genotyping algorithm is crucial to identify new SNPs associated to disease risk. Recently, new methods…Abstract Number: 1002 • 2012 ACR/ARHP Annual Meeting
Microrna Expression Profiles in Peripheral Blood Mononuclear Cells of Early Onset Psoriatic Arthritis
Background/Purpose: Micro-RNAs (miRNAs) are small non-coding RNAs that negatively regulate gene expression. It is known that an altered miRNA expression plays an important role in…Abstract Number: 1003 • 2012 ACR/ARHP Annual Meeting
Role of Particular Class I MHC Haplotypes in Determining Different Traits within the Psoriatic Arthritis Phenotypes
Background/Purpose: A rigorously ascertained psoriatic arthritis (PsA) cohort demonstrated considerable genetic heterogeneity and provided preliminary evidence that MHC genes determine quantitative traits within the PsA…Abstract Number: 1004 • 2012 ACR/ARHP Annual Meeting
