New research has demonstrated that a high-salt diet may increase the differentiation of follicular helper T cells (Tfh). A high-salt diet also increased lupus features in MRL/lpr mice, suggesting that the genes that increased expression in response to salt intake were similar to the genes that had increased expression in lupus CD4+ T cells…
A recent study documented blood transcriptional profiles in pediatric patients with systemic lupus erythematosus (SLE), finding that plasmablast signatures were the most robust biomarker of SLE disease activity. Researchers were further able to stratify patients into groups on the basis of molecular correlates, which may aid in personalizing SLE treatment and identifying biomarkers that can predict occurrence and frequency of flares…
New research investigates the role of autophagy, specifically the cell digestion process called LC3-associated phagocytosis (LAP), in inflammation and the pathology of systemic lupus erythematosus (SLE). Researchers found that defects in this process result in failure to digest dying cells, which increases inflammatory cytokine production and results in SLE-like disease in mice. Further exposure to dying cells accelerated disease development…
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…
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…
