Association Between The Presence Of Amyloidosis In Patients With Ankylosing Spondylitis and Polymorphisms In Type 1/Type 2 Serum Amyloid A Protein Genes, Mediterranean Fever Genes
Background/Purpose: Ankylosing spondylitis (AS) is a chronic autoinflammatory disease. The most severe complication of this disease is development of renal amyloidosis. The etiology of AS remains…Abstract Number: 524 • 2013 ACR/ARHP Annual Meeting
Expansion Of DC-STAMP+ IL-17+ Cells In Bone Marrow From Psoriasis and Psoriatic Arthritis Patients
Background/Purpose: Focal erosions in inflammatory arthritis are mediated by bone marrow (BM) derived osteoclasts (OC) that enter the joint as OC precursors (OCP) from peripheral…Abstract Number: 525 • 2013 ACR/ARHP Annual Meeting
Evidence For Enhanced Induction Of Unfolded Protein Response Target Genes In Peripheral Blood Mononuclear Cells From Spondyloarthritis Patients
Background/Purpose: Spondyloarthritis (SpA) is an immune-mediated inflammatory disease strongly associated with HLA-B27 (B27). In a transgenic rat model where B27 causes SpA-like disease, CD8 T…Abstract Number: 526 • 2013 ACR/ARHP Annual Meeting
Endochondral Bone Formation and Advanced Enthesitis Are Key Features Of Proteoglycan Induced Spondylitis Mouse Model Of Ankylosing Spondylitis
Background/Purpose: Transition from an initial inflammatory phase to the disabling osteoproliferative phase in ankylosing spondylitis (AS) is very poorly understood. Elucidation of the mechanisms underlying…Abstract Number: 527 • 2013 ACR/ARHP Annual Meeting
Presence Of Gastrointestinal Symptoms and Autoantibodies In Patients With Spondyloarthritis In A Colombian Population
Background/Purpose: The frequency of gastrointestinal (GI) involvement in spondyloarthritis (SpA) ranges from 21% to 30% and 5% to 10% are associated with inflammatory bowel disease…Abstract Number: 528 • 2013 ACR/ARHP Annual Meeting
Upregulated Th17 and Innate Pathways Are More Characteristic Of The Skin Than The Synovium In Psoriatic Arthritis
Background/Purpose: Psoriatic arthritis (PsA) is an inflammatory joint disease associated with psoriasis. There is little understanding of the relative levels of cytokines and chemokines between…Abstract Number: 529 • 2013 ACR/ARHP Annual Meeting
Ankylosing Spondylitis and Dysfunctional Dkk
Background/Purpose: Ankylosing Spondylitis (AS) is characterized by inflammation of the spine and entheses followed by formation of syndesmophytes. Wnt pathway is a regulator of bone…Abstract Number: 530 • 2013 ACR/ARHP Annual Meeting
Pattern Recognition Receptor Stimulated Cytokine Expression By Spondyloarthritis Patient Macrophages
Background/Purpose: Spondyloarthritis (SpA) encompasses a group of chronic inflammatory conditions involving axial arthritis that includes ankylosing spondylitis (AS). GWAS studies in AS have implicated multiple…Abstract Number: 532 • 2013 ACR/ARHP Annual Meeting
Role Of Baseline C-Reactive Protein In Response To Infliximab Plus Naproxen Vs Naproxen Alone In Patients With Axial Spondyloarthritis
Background/Purpose: Baseline inflammation has been shown to influence response to tumor necrosis factor alpha antagonist treatment in patients with axial spondyloarthritis (SpA). This study evaluated…Abstract Number: 535 • 2013 ACR/ARHP Annual Meeting
Death Receptor 3 Increases Region-Specific, Osteoblast-Dependent Aberrant New Bone Formation In The Axial Skeleton Of Mice In a Spontaneous Model Of Ankylosing Enthesopathy
Background/Purpose: Clinical management of localised bone formation and joint ankylosis constitute major challenges in patients with seronegative inflammatory spondyloarthropathies (SpAs). Whether TNF receptor superfamily members,…Abstract Number: 536 • 2013 ACR/ARHP Annual Meeting
Membrane-Bound TNF Drives Axial and Peripheral Inflammation and Pathologic New Bone Formation
Background/Purpose: The morbidity of spondyloarthritis (SpA) is determined not only by inflammation but also by structural damage, in particular osteoproliferation leading to joint ankylosis. The…Abstract Number: 537 • 2013 ACR/ARHP Annual Meeting
Investigating a Novel Locus For Psoriatic Arthritis
Background/Purpose: Psoriatic arthritis (PsA) is a complex genetic disorder with a prevalence of up to 1% in the general population. The association of PsA with…Abstract Number: 538 • 2013 ACR/ARHP Annual Meeting
Ankylosing Spondylitis Associated Endoplasmic Reticulum Aminopeptidase 1 Variants Alter The Unfolded Protein Response
Background/Purpose: Endoplasmic reticulum aminopeptidase 1 (ERAP1) has recently been identified to be strongly associated with HLA-B27 positive AS. We have shown that ERAP1 variants cause…Abstract Number: 540 • 2013 ACR/ARHP Annual Meeting
Exploration Of a Novel Therapeutic Target In a Murine Model Of Systemic Lupus Erythematosus: Targeting Sphingosine-1-Phosphate (S1P) Receptors
Background/Purpose: Systemic lupus erythematous (SLE) is an autoimmune disease characterized by symptomatic flares that often result in terminal organ failure. The pathogenesis is characterized by…Abstract Number: 541 • 2013 ACR/ARHP Annual Meeting
