Background/Purpose: Visual manifestations such as diplopia, amaurosis fugax or blindness occur in up to half of the giant cell arteritis (GCA) patients. Some studies have…Abstract Number: 1665 • 2013 ACR/ARHP Annual Meeting
B Cells Revisited In Giant Cell Arteritis
Background/Purpose: Giant cell arteritis (GCA) is a primary vasculitis affecting large to medium-sized arteries. Ample evidence suggests that dendritic cells, T cells and monocytes/macrophages contribute…Abstract Number: 1666 • 2013 ACR/ARHP Annual Meeting
Negative Temporal Artery Biopsies: Pathologic Findings Of Patients With Biopsy-Negative Giant Cell Arteritis Compared To Those Of Patients Without Arteritis
Background/Purpose: Temporal artery biopsy (TAB) showing transmural inflammation is considered the gold standard for the diagnosis of giant cell arteritis (GCA). A negative TAB does…Abstract Number: 1677 • 2013 ACR/ARHP Annual Meeting
May Giant Cell Arteritis Be Characterized By Different Clinical Entity and Long-Term Outcome?
Background/Purpose: Giant cell arteritis (GCA) represents the most common primary vasculitis of the elderly, that affect large and medium-sized arterial vessels. Growing data shown that…Abstract Number: 1678 • 2013 ACR/ARHP Annual Meeting
How Similar Are Extracranial Giant Cell Arteritis and Takayasu Arteritis?
Background/Purpose: The clinical and radiographic features of giant cell arteritis (GCA) with extracranial (large-vessel) involvement can be similar to those of Takayasu arteritis (TAK)…Abstract Number: 1664 • 2013 ACR/ARHP Annual Meeting
Lower Tissue Expression Of IL 6 In Patients With Giant Cell Arteritis Presenting With a Cranial Ischaemic Compication
Background/Purpose: Giant Cell Arteritis (GCA) is a granulomatous systemic vasculitis with a prediliction for the aorta and it’s extracranial branches. The majority of the morbidity…Abstract Number: 892 • 2013 ACR/ARHP Annual Meeting
The Functional PTPN22 Variant R620W Is Strongly Associated With Giant Cell Artetitis Predisposition
Background/Purpose: The PTPN22/CSK signaling represents one of the common susceptibility pathways in autoimmunity. Considering that the genetic basis of giant cell arteritis (GCA), an autoimmune…Abstract Number: 896 • 2013 ACR/ARHP Annual Meeting
Increased Rho Kinase (ROCK) Activity In Temporal Artery Biopsies From Patients With Giant Cell Arteritis (GCA)
Background/Purpose: ROCKs are implicated in the pathogenesis of many vascular diseases. ROCK activation is associated with Th17 differentiation and production of Th17-associated cytokines, IL-17 and…Abstract Number: 2360 • 2012 ACR/ARHP Annual Meeting
Prevalence, Management and Outcomes of PET Positive Large Vessel Vasculitis in Difficult to Treat PMR and GCA Patients
Background/Purpose: Management of PMR and GCA can be challenging in patients with persistently elevated inflammatory markers, prominent constitutional symptoms and inadequate steroid response. We undertook…Abstract Number: 859 • 2012 ACR/ARHP Annual Meeting
Endothelin-1 (ET-1) Induces Extracellular Matrix Protein Production by Human Temporal Artery Derived Myointimal Cells. A Mechanism Potentially Leading to Intimal Hyperplasia and Vascular Occlusion in Giant-Cell Arteritis
Background/Purpose: Endothelin-1 (ET-1) is the main isoform of the Endothelin family. It is also the most powerful vasoconstrictor identified. ET-1 is constitutively produced in blood…Abstract Number: 2568 • 2012 ACR/ARHP Annual Meeting
The Risk of Pulmonary Embolism and Deep Vein Thrombosis in Giant Cell Arteritis: A Population-Based Cohort Study
Background/Purpose: A recent hospital-based study has suggested an 8 fold increased risk of pulmonary embolism (PE) in individuals with polymyalgia rheumatica in the year following…Abstract Number: 2390 • 2012 ACR/ARHP Annual Meeting
Color Doppler Ultrasonography an Alternative to CT/MR Angiography for Identifying Large Vessel Involvement in Giant Cell Arteritis?
Background/Purpose: Large vessel involvement has been reported to be present in 20-50% of patients with giant cell arteritis (GCA). Computed tomography (CT) and magnetic resonance…
