People with or at risk for symptomatic knee osteoarthritis (OA) may be assigned to four depression subtypes with distinct clusters of depressive symptoms that may affect pain and disability over time, according to a new study in Arthritis Care & Research.1 Four depression subtypes were identified in the study using the Center for Epidemiologic Studies…
How laboratories define a serological hallmark of systemic lupus erythematous and which assays they use to detect it could contribute to misclassification of patients identified as anti-nuclear antibody (ANA) negative, according to researchers. Most people who have lupus test positive for ANAs as part of an immunology screening for autoimmune disorders. The presence of ANAs…
The identification of specific transcription factors linked to the Epstein-Barr virus (EBV) provides new information on the molecular mechanisms underlying the link between EBV and autoimmune disease. A recently published study, “Transcription Factors Operate Across Disease Loci, with EBNA2 Implicated in Autoimmunity,” co-led by John B. Harley, MD, PhD; Leah C. Kottyan, PhD; and Matthew…
The ACR’s RISE registry offers answers on real-world experience to researchers.
Funck-Brentano et al. hypothesized that causal associations for osteoarthritis (OA) may differ by site, and they undertook this study to identify causal risk factors of knee, hip and hand OA.
(Reuters Health)—Behavior changes could potentially reduce a large part of the risk for developing gout, a U.S. study suggests. Based on data from more than 14,000 people, researchers calculated how much factors like being overweight, following a diet that isn’t heart healthy, drinking alcohol or taking diuretics contribute to high levels of uric acid—a precursor…
As the 21st century unfolds, rheumatologists will most likely transition from prescribing lupus patients broad immunosuppressants to more targeted treatment approaches. But to make this happen and advance research, the challenges experienced in lupus clinical trial design must be addressed…
The Rheumatology Research Foundation hosted the 13th annual Investigators Meeting in Washington, D.C., June 22‒23. The meeting provides Foundation-funded researchers with an opportunity to share updates on their studies, network, exchange ideas and collaborate on future projects to advance treatments and cures for rheumatic diseases. More than 50 rheumatology professionals were in attendance, with presentations…
An antibody previously un-recognized in patients with Sjögren’s syndrome may shed new light on the pathophysiology of one of the most troubling and disabling symptoms in many of these patients. Investigators at Johns Hopkins University, Baltimore, found the anti-calponin 3 antibody had a high specificity for Sjögren’s syndrome, particularly among patients with neuropathies.1 “There is…
Researchers know human leukocyte antigen (HLA) molecules affect susceptibility to disease in general, and immunological disease in particular. In the case of ankylosing spondylitis (AS), the risk is primarily associated with HLA-B27, with smaller effects from other HLA alleles. Current thinking is that AS is caused by the presence of a genetically primed host because…
