Background/Purpose: In recent years, Temporal Artery US (TAUS) incorporating Axillary Artery US (AAUS) has become a reliable alternative to biopsy for diagnosing GCA but studies…Abstract Number: 2419 • ACR Convergence 2023
Visual Manifestations in Giant Cell Arteritis: Identification of Risk Factors from the ARTESER Registry
Background/Purpose: Visual loss is one of the most feared complications in giant cell arteritis (GCA). Some factors have been previously associated with visual loss, as…Abstract Number: 1040 • ACR Convergence 2023
Impact of Ultrasound Limitation to Assess Aortitis in Patients with Giant Cell Arteritis: Comparative Study with FDG-PET/CT
Background/Purpose: Aortitis is a serious potential complication of patients with giant cell arteritis (GCA) and may lead to dilation, aneurysms or dissection. Since ultrasound (US)…Abstract Number: 2085 • ACR Convergence 2023
A Survey on Giant Cell Arteritis-Related Knowledge Among Internal Medicine Residents
Background/Purpose: Giant Cell Arteritis (GCA) poses challenges in clinical practice, necessitating a deep understanding. Internal medicine residents play a crucial role in patient care and…Abstract Number: 2402 • ACR Convergence 2023
A Retrospective Analysis of Prevalence of Positive Temporal Artery Biopsies in African American Patients with Giant Cell Arteritis (GCA) in a Large Academic Health Center
Background/Purpose: Giant Cell Arteritis (GCA) is a systemic vasculitis reportedly more common in Caucasian older adults. Studies suggest that GCA is very rare in African…Abstract Number: 2420 • ACR Convergence 2023
Sex Differences in Giant Cell Arteritis: Data from the ARTESER Registry
Background/Purpose: Giant cell arteritis (GCA) is the most common vasculitis in North America and Western Europe. GCA is more likely to occur in women (1).…Abstract Number: 1049 • ACR Convergence 2023
Enhanced Diagnostic Confidence with High Frequency Temporal Artery Ultrasound in Diagnosis of Cranial Giant Cell Arteritis (GCA)
Background/Purpose: A previous survey of Australian Rheumatologists indicated low confidence (60% of Australian Rheumatologists) in the use of Temporal artery ultrasound provided by their Radiology…Abstract Number: 2373 • ACR Convergence 2023
SIRPα Expression in Systemic Vasculitis
Background/Purpose: Signal regulatory protein alpha (SIRPα) is primarily found on myeloid cells, including macrophages and neutrophils. Upon binding to CD47, SIRPa signaling regulates various cellular…Abstract Number: 2403 • ACR Convergence 2023
Systole and Diastole Ultrasound Wall Thickness Shows Significant Differences That Affect the Diagnosis and Assessment of Giant Cell Arteritis
Background/Purpose: In the last few years, several cut-off points for the intima-media thickness (IMT) of temporal arteries (TA) and large vessels (LV) have been proposed…Abstract Number: 2421 • ACR Convergence 2023
Optic Nerve Sheath Measurement on Ultrasound: A Novel Diagnostic Test for Giant Cell Arteritis
Background/Purpose: Confirming the diagnosis of giant cell arteritis (GCA) remains challenging. Available diagnostic tests have limited accuracy and availability. Recently, optic nerve sheath enhancement on…
