NEW YORK (Reuters Health)—Inpatient dermatology consultations were associated with shorter hospital stays and reduced readmissions in a U.S. medical center and may do the same elsewhere, researchers in Ohio suggest. “A few decades ago, patients with severe psoriasis, drug reactions, blistering diseases and even severe eczema would be admitted to the hospital under close dermatology…
Liquid Biopsy Provides Insights into Lupus
Microparticles in the blood of SLE patients may be a source of extracellular HMGB1, which is involved in immune response. Researchers found that analysis may be able to determine if the patient is producing dead, dying and activated cells that are important for SLE pathogenesis…
Accelerating Medicines Partnership Advances Research for Autoimmune Diseases
Advancing the understanding of autoimmune diseases has implications for precision medicine, according to Robert Carter, MD, of the NIH. Research funded through the NIH’s Accelerating Medicines Partnership has the potential to develop better biomarkers and clinical trials for lupus and RA, paving the way for more personalized treatment…
High-Salt Diet May Trigger Gene Silencing & a Lupus Phenotype
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…
Plasmabast Responses Provide a Signature for Lupus Disease Activity
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…
Researchers Hone in on Defect in Autophagy that May Underlie Lupus
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…
Researchers Calculate Comorbidity Burden for Patients with SLE
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…
Bacterial Curli Amyloid: Researchers Examine the Role of Bacterial Infection in Lupus Pathology
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…
U.K. Cost Body Finally Approves Limited Use of GSK’s Lupus Drug
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…
Patients with Lupus: Plasmacytoid Dendritic Cells Fail to Induce Regulatory B Cells
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…
