NEW YORK (Reuters Health)—Pregnancy outcomes in women with systemic lupus erythematosus (SLE) have improved markedly over the past two decades, although pregnancy risks remain higher than in women without lupus, according to a trends analysis. “Thirty years ago, most women with SLE were advised to avoid pregnancy because of high risks for maternal and fetal…
Low-Density Granulocytes Activate T Cells in SLE
Recent research indicates that low-density neutrophils, such as low-density granulocytes, exert proinflammatory effects on the T cells of SLE patients. In the study, researchers confirmed SLE patients had a higher prevalence of low-density granulocytes than healthy controls and that these cells appeared to promote a Th1 response…
Insight into Clinical Trials for Lupus
Research into lupus treatments suffered a setback after the failure of anifrolumab in clinical trials. However, during the 2019 ACR State-of-the-Art Clinical Symposium, Richard Furie, MD, outlined the possibilities of multiple new lupus therapies under investigation…
Ixekizumab Promising for Non-Radiographic Axial SpA; Plus FDA Approves Belimumab for Pediatric Lupus
Results from a Phase 3 study showed ixekizumab significantly improved the signs and symptoms of non-radiographic axial spondyloarthritis in patients…
Characterization of Autoreactive B Cells in Patients with SLE & RA
Antibody-secreting cells are important for the pathophysiology of SLE and RA, but researchers have been unable to determine how these cells are activated. A new technique is able to distinguish between naïve autoreactive B cells and established antibody secreting cells…
Anti-Mitochondrial Antibodies & Systemic Lupus Erythematosus
Although antimitochondrial antibodies are present in SLE patients, researchers have has difficulty investigating the phenomenon due to barriers in isolating pure mitochondria. The study describes a technique that allows for such an investigation and provides insight into how the adaptive immune system recognizes mitochondrial organelles…
Metabolic Profiling of SLE
Research examining the metabolic profile of SLE found increased oxidative activity, as well as lower levels of tyrosine and tryptophan, in SLE patients relative to controls, suggesting increased activity of aromatic amino acid decarboxylase. The results suggest metabolomics may have the ability to measure disease severity in SLE…
History of Depression Is a Risk Factor for SLE in Women
Results from a 20-year, cohort study add to the evidence that depression increases the risk of developing an autoimmune disease, specifically SLE in women. Lead investigator Andrea Roberts, PhD, says, “There may be direct biological effects of depression that increase the risk of autoimmune disease.”…
Mortality Trends in Lupus Nephritis
According to results of a recent study of all-cause and cause-specific mortality trends of end-stage renal disease due to lupus nephritis from 1995 to 2014, the all-cause premature mortality rate improved among white, African American and Hispanic patients, with reduced risk of death from CVD and infection. Jorge et al. observed a 32% reduction in mortality. This improved survival may be explained by a combination of improvements in the management of ESRD and of underlying SLE…
Alterations in Macrophage Activation May Signal a Lupus Flare
New data suggest myeloid cells in SLE patients skew B and T cell activation status toward the M1 proinflammatory phenotype, thereby directing SLE flares and remission…
