Past research has identified being of Northern European descent as a risk factor, among others such as age, sex and HLA DRB1, for developing giant cell arteritis (GCA). But new research casts doubts on this idea, finding that rates of biopsy proven GCA may not differ by race…... [Read More]
Patients with polymyalgia rheumatica (PMR) or peripheral arthritis may require extra vigilance during treatment because of a suspected link to giant cell arteritis (GCA) and, potentially, permanent vision loss. “Development of giant cell arteritis after treating polymyalgia or peripheral arthritis: a retrospective case-control study,” a March 2018 study published in The Journal of Rheumatology, suggests… [Read More]
AMSTERDAM—Just how seldom prednisone is successful at inducing remission in giant cell arteritis (GCA), despite such a long history of use for the disease, is one of the many lessons to emerge from the data in the GiACTA trial, said the principal investigator of the trial, which is the largest ever in GCA and is… [Read More]
Baltimore—Rheumatologists and meteorologists share more in common than you might suspect, said Dr. Rebecca Manno, assistant professor of medicine for the Division of Rheumatology at Johns Hopkins University, Baltimore, and assistant director of the Johns Hopkins Vasculitis Center. At a March 8 meeting of the Maryland Society for the Rheumatic Diseases, Dr. Manno used the… [Read More]
A proposed model to predict the risk of giant cell arteritis (GCA) prior to a temporal artery biopsy could help triage patients and guide decision making about the need for biopsy or monitoring (see Figure 1). There’s no specific biomarker for GCA, and GCA can be a “diagnostic conundrum, especially when it presents in an… [Read More]
SAN DIEGO—Recent research tells us more about giant cell arteritis (GCA) to help rheumatologists more accurately diagnose and effectively treat patients with this type of vasculitis. On Nov. 6 at the ACR/ARHP Annual Meeting, three experts explored the latest findings on GCA pathogenesis, diagnostic approaches, imaging modalities and growing treatment options. GCA: What’s Really Happening?… [Read More]
A recent study, conducted by the Vasculitis Clinical Research Consortium and funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), examined whether the addition of abatacept, a drug that affects T cell activation, to standard prednisone treatment could reduce the risk of relapse in patients with giant cell arteritis (GCA).1 Although… [Read More]
GCA Relapse Possible When Discontinuing Tocilizumab In a Phase 2 randomized, controlled trial, tocilizumab, an anti-IL-6 biologic agent, was shown to induce and maintain remission for up to 52 weeks in patients with giant cell arteritis (GCA).1 During this trial, patients with GCA were randomized in a 2:1 ratio to receive 8 mg/kg bodyweight tocilizumab… [Read More]
WASHINGTON, D.C.—From diagnosis questions to infection risk to treatment decisions, handling giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) comes with a range of challenges for clinicians. Speaking in the ACR Review Course at the 2016 ACR/ARHP Annual Meeting, an expert—Rebecca Manno, MD, MHS, assistant professor of medicine in rheumatology at Johns Hopkins, as well… [Read More]
Researchers have recently discovered a connection between the varicella zoster virus infection, which causes chicken pox and shingles, and giant cell arteritis…... [Read More]
