Role of Synovial Biopsy in Diagnosis of Crystal Arthropathies
Title: Role of Synovial Biopsy in Diagnosis of Crystal Arthropathies Background/Purpose: Diagnosis of crystal arthropathies (CAs) can be challenging. Advances in arthroscopy and ultrasound guided…Abstract Number: 674 • 2016 ACR/ARHP Annual Meeting
Targeting Glandular IL-21-Production in Primary Sjogren′s Syndrome Patients By Immunomodulatory Treatment
Background/Purpose: Interleukin-21 plays a central role in plasma cell differentiation and germinal center (GC) formation and is likely involved in the pathogenesis of primary Sjögren’s…Abstract Number: 856 • 2016 ACR/ARHP Annual Meeting
Rho Kinase Ezpression in Giant Cell Arteritis: Validating Perm Intensity Score As a Method of Increasing Sensitivity of Temporal Artery Biopsy
Background/Purpose: Aberrant rho-kinase (ROCK) activity is implicated in pathogenesis of several vascular and immunologic disorders. We previously demonstrated evidence of increased ROCK activity in histopathologically…Abstract Number: 866 • 2016 ACR/ARHP Annual Meeting
Perivascular Inflammation in Temporal Artery Biopsies That Are Negative for Arteritis: Incidental or Harbinger?
Background/Purpose: The diagnosis of giant cell arteritis (GCA) by temporal artery (TA) biopsy requires pathologic identification of arterial inflammation, usually with giant cells. However, some…Abstract Number: 891 • 2016 ACR/ARHP Annual Meeting
Clinal Characterisitics and Diagnosis of Patients with Negative Temporal Artery Biopsy and without a Final Diagnosis of Giant Cell Arteritis
Background/Purpose: To describe the characteristics and diagnosis of patients with negative temporal artery biopsy (TAB) for whom a final diagnosis of giant cell arteritis (GCA)…Abstract Number: 894 • 2016 ACR/ARHP Annual Meeting
Laboratory Tests in Giant Cell Arteritis – Do They Make the Cut?
Background/Purpose: The initial suspicion of Giant cell arteritis (GCA) is often made in the setting of primary care or casualty by a non-rheumatologist. Whilst temporal…Abstract Number: 646 • 2015 ACR/ARHP Annual Meeting
Sicca Syndrome in Rheumatoid Arthritis: Is It a Real Sjögren’s?
Background/Purpose: The histopathological hallmark and a major diagnostic criterion of Sjögren’s syndrome (SS) is the presence of periductal lymphocytic infiltrates in the labial minor salivary…Abstract Number: 1960 • 2015 ACR/ARHP Annual Meeting
a Structured and Extensive Training Program on Vascular Ultrasound, Results in an Excellent Agreement Between Ultrasound and Temporal Artery Biopsy in the Diagnosis of Giant Cell Arteritis
Background/Purpose: There is an increased use of vascular ultrasound (US) for diagnosing giant cell arteritis (GCA). Consequently, extensive and structured training of ultrasonographers performing vascular…
