Eosinophilia is usually defined as an eosinophil count of more than 500/microL in peripheral blood.1 An eosinophil count of more than 1,500 is referred to as hypereosinophilia (HE); hypereosinophilic syndrome (HES) is defined as HE associated with organ dysfunction attributable to eosinophilia.2 Eosinophilia can occur due to infectious, malignancy, autoimmune or allergic etiologies. However, a…
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…
In 1866, Adolf Kussmaul, an internist, and Rudolf Maier, a pathologist, published the classic characterization of what eventually became known as polyarteritis nodosa.1 It was the first scientific clinical characterization of a noninfectious vasculitis. As such, it became a paradigmatic point of contrast to other types of vasculitides that were later described. Their description also…
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?…
SAN DIEGO—At the 2017 ACR/ARHP Annual Meeting this past November, three researchers discussed the latest ANCA-associated vasculitis (AAV) research, including studies on AAV pathogenesis, therapies and remission maintenance. In the Philip Hench, MD, Memorial Lecture, J. Charles Jennette, MD, chair in pathology and laboratory medicine at the University of Carolina at Chapel Hill in Chapel…
SAN DIEGO—An increasing number of patients is being identified with deficiency of adenosine deaminase type 2 (DADA2); fortunately, researchers and clinicians continue to better understand the genetic disease as well, experts said in a session at the 2017 ACR/ARHP Annual Meeting Nov. 3–8. The childhood-onset disease involves loss-of-function mutations to the CECR1 gene (i.e., cat…
SAN DIEGO—At the 2017 Thieves Market, held Nov. 6 at the ACR/ARHP Annual Meeting, rheumatologists from around the world presented patient cases to an audience of colleagues, who then voted via text messaging to choose the cases they felt were most perplexing or intriguing. The winner received a free 2018 Annual Meeting registration, and the…
SAN DIEGO—Top researchers gathered for a review course at the start of the 2017 ACR/ARHP Annual Meeting in November to describe new research, their own treatment strategies and new ways of thinking about an array of rheumatic diseases. Here are the highlights: Raynaud’s & Other Digit Problems When a patient walks into your clinic with…
NEW YORK (Reuters Health)—Patients with suspected large-vessel vasculitis (LVV) should undergo early imaging, the European League Against Rheumatism (EULAR) advises in a new report presenting a dozen evidence-based recommendations for the use of imaging in primary LVV. Ultrasound should be the first choice for giant-cell arteritis (GCA), while MRI should take precedence for Takayasu arteritis…
NEW YORK (Reuters Health)—Patients with polymyalgia rheumatica (PMR) and giant-cell arteritis (GCA) have similarly increased risks of fracture, compared with the general population, researchers have found. “It is of surprise that patients with GCA have a similar fracture risk to those with PMR,” Dr. Zoe Paskins from Keele University, in Staffordshire, told Reuters Health by…
