Cannabis arteritis mirrors thromboangiitis obliterans in its clinical and arteriographic presentation, but its relevant exposure is cannabis rather than tobacco.1 Whether cannabis arteritis is a subset of thromboangiitis obliterans or a unique pathologic entity is debatable. Delta-9-tetrahydrocannabinol, the primary psychoactive component of cannabis, is a peripheral vasoconstrictor.2 This offers mechanistic insight into how cannabis may…
The Basic and Clinical Research Conference session on Rheumatology Complications of Emerging Viral Infections/SARS-CoV-2 presented findings from numerous studies that help explain some of the idiosyncrasies of COVID-19.
More than 7 million doses of the Johnson & Johnson single-dose vaccine have been administered in the U.S.1 On Apr. 23, the Centers for Disease Control & Prevention (CDC) and the U.S. Food & Drug Administration (FDA) recommended lifting the recommended pause on Johnson & Johnson COVID-19 vaccine use following a thorough safety review. 2…
Dermatomyositis is an uncommon autoimmune condition involving skeletal muscle characterized by subacute onset of progressive weakness, intramuscular inflammatory infiltrates and the presence of myositis-specific autoantibodies.1 Immune-mediated myopathies may exert some pathogenic effects on the muscle tissue by targeting the microvasculature.1 Capillary inflammation, fragility and loss may contribute to heightened bleeding events in these patients. Here,…
A 24-year-old woman presented to our rheumatology office in 2017 with a blotchy purple rash on her arms and legs. She reported no history of miscarriage or blood clots. The rash pattern was concerning for livedo reticularis or livedo racemosa, and she was noted to have an anti-nuclear antibody (ANA) titer of 1:160 with a…
Three experts discuss recent developments in the diagnosis & treatment of APS & the future direction of research.
Early results in a phase 2 trial are finding that adding a TNF blocker to other treatment could greatly lower the risk of serious complications during pregnancy for women who have antiphospholipid syndrome with lupus anticoagulant.
For women with antiphospholipid syndrome (APS), treatment with a combination of heparin and aspirin during pregnancy—rather than aspirin alone—may increase live birth rates, according to new research.
CHICAGO—Choosing a treatment for antiphospholipid syndrome (APS) involves an array of factors, from the antibodies present to their titers to other risk factors, said Lisa Sammaritano, MD, during a guided tour of APS treatment at the 2019 ACR State-of-the-Art Clinical Symposium, held April 5–7. Dr. Sammaritano, associate attending physician at the Hospital for Special Surgery,…
The pathogenesis of antiphospholipid syndrome (APS) is complicated and may involve local inflammation, vasculopathy, pregnancy complications and thrombosis. During the 2019 ACR State-of-the-Art Clinical Symposium, Lisa Sammaritano, MD, addressed the risk assessment and treatment of APS patients…
