New research has found that the amyloid protein curli triggers immune activation and autoantibody production in lupus-prone and wild-type mice. Stefania Gallucci, MD, says these results provide insight into the mechanisms of bacterial infection that may result in lupus…
LONDON (Reuters)—Britain’s healthcare cost watchdog has finally approved GlaxoSmithKline’s lupus drug Benlysta (belimumab) for limited use, after rejecting it since 2011 on the grounds that it failed to offer good value for money. The National Institute for Health and Care Excellence (NICE) said on Tuesday that the drug would be made available under a managed…
A recent study found that plasmacytoid dentricitic cells (pDCs) control the differentiation of immature B cells into regulatory B (Breg) cells or plasmablast, depending on the concentration of IFNα. For patients with SLE, researchers found that immune regulatory feedback between pDCs and Breg cells is dysfunctional, with the exception of patients who respond to rituximab…
Clinical trials have begun to determine if disodium zoledronate tetrahydrate is safe and effective for treating pain in patients with knee osteoarthritis. The FDA has approved the use of ixekizumab for the treatment of plaque psoriasis. And a study has shown that patients with SLE treated with belimumab may be able to decrease steroid use…
NEW YORK (Reuters Health)—Sifalimumab, an anti-interferon alpha monoclonal antibody, may lead to some improvement in patients with systemic lupus erythematosus (SLE), according to a new trial. In a paper online on March 23 in Annals of the Rheumatic Diseases, Dr. Munther Khamashta of King’s College London and colleagues note that treatment of SLE presents a…
A new study has found that treating patients who have systemic lupus erythematosus (SLE) with vitamin D decreases cardiovascular risk in these patients—specifically by modifying the body’s endothelial repair mechanisms. Researchers found myeloid angiogenic cells in this patient population presented with a global impairment, including decreased migration and angiogenic capacity…
Abaloparatide has completed clinical trials, which showed the treatment to be safe and effective in reducing fracture rates in postmenopausal women with osteoporosis. Also, XmAb5871 is being studied to treat systemic lupus erythematosus and doesn’t destroy B cells…
New research examines how the generation of reactive oxygen species and neutrophil extracellular traps may break down the protective mechanisms of mitochondrial DNA, resulting in NETosis in people with autoimmune disease. They found oxidized mitochondrial DNA may contribute to inflammation in such diseases as systemic lupus erythematosus by upregulating type I interferon signatures…
SAN FRANCISCO—Two hundred years ago, physicians knew nothing about what caused various forms of arthritis. Today, we have more clues about what may trigger rheumatic diseases, but still can’t pinpoint the culprits that set scores of inflammatory conditions in motion. Researchers discussed some of the background and recent findings that point to what immunologists call…
SAN FRANCISCO—Let’s say your radiologist comes to you and says that an angiogram gives a diagnosis of CNS vasculitis on four patients, all with acute onset of headache and stroke: One is a 25-year-old woman who is three months pregnant. Another is a 50-year-old man using excessive doses of nasal decongestants. Another is a 40-year-old…
