The serine-threonine protein phosphatase 2A (PP2A) enzyme is critical for regulatory T cells to function—without it, they don’t have the ability to suppress effector T cells and can’t protect against autoimmunity, according to new research published in Nature Immunology. Researchers found that conditional knockout mice—in which PP2A expression is knocked out only in regulatory T cells—developed…
The Rheumatology Research Foundation recently received its seventh consecutive four-star rating from Charity Navigator. This prestigious, highest rating possible is based on good governance, sound fiscal management and commitment to accountability and transparency. As the nonprofit sector continues to grow at an unprecedented pace, savvy donors are demanding more accountability, transparency and quantifiable results from…
A recent study from the U.K. calculated the incidence of comorbidity associated with systemic lupus erythematosus (SLE), specifically looking for cardiovascular disease, stroke, end-stage renal failure, cancer, osteoporosis and infection. Even after adjusting for age, sex and other variables, investigators found that people with SLE have an increased global burden of comorbidity compared with the general population. Additionally, the study found that men with SLE had higher rates of cardiovascular disease, stroke and cancer, while women with SLE had higher rates of infection and osteoporosis. Overall, younger people with SLE had the greatest relative risk compared with controls…
A variety of immune and nonimmune pathophysiologic mechanisms causing the disruption of alveolar capillaries with bleeding into the alveolar spaces can lead to diffuse alveolar hemorrhage (DAH). Immune-mediated mechanisms can cause DAH with or without the presence of capillaritis. The antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) syndromes—granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA)—are the…
A recent editorial in Arthritis & Rheumatology explored the role of sensitization, not nociception, as a key mechanism of pain for patients with knee OA, as well as inflammation’s role in pain perception. Recent research of synovitis and joint effusion supports the idea that early prevention or treatment of sensitization may be paramount to reducing long-term pain in patients with knee OA…
A recent review in Arthritis & Rheumatology examined advances in addressing the pathophysiology, genetics and treatment of enthesitis for patients with spondyloarthritis. And author Michael Weisman, MD, notes that challenges remain in understanding the genetics and triggers of enthesitis…
May is recognized as National Arthritis Awareness Month, a time to bring attention to the more than 46 million Americans living with arthritis and related inflammatory diseases. In honor of the occasion, the Rheumatology Research Foundation is launching #RheumLife, a social media campaign to bring awareness to the severity of rheumatic disease. Through Twitter and…
April 5, 2016, marks a revolutionary day in the treatment of autoimmune diseases: The U.S. Food and Drug Administration (FDA) approved an infliximab (Remicade) biosimilar, known as Inflectra (infliximab-dyyb). Infliximab-dyyb, which is administered by intravenous infusion, is the first biosimilar drug approved to treat rheumatic disease in the U.S.1 Infliximab-dyyb has received approval for almost…
In February, new recommendations were released for the treatment of ankylosing spondylitis and nonradiographic axial spondyloarthritis, noting that NSAIDs may be the best initial treatment for the diseases, with TNF inhibitors as second-line therapies. The guideline was the result of a joint effort by the ACR, the Spondylitis Association of America and the Spondyloarthritis Research and Treatment Network…
Foot osteoarthritis (OA) of the first metatarsophalangeal (MTP) joint is thought to have biomechanical factors, but its treatments have not been comprehensively tested in clinical trials. In the first study to explore the efficacy of mechanical interventions, researchers compared the effectiveness of foot orthoses and rocker-sole footwear in reducing pain. Both interventions were effective, but the foot orthoses group wore the intervention for significantly more hours than the footwear group…
