A recent gene expression analysis found an enriched downstream interferon signature, with predominantly IFNB1 signatures in systemic lupus erythematosus (SLE) patients. The study also found lower expression of all downstream interferon signatures in the kidneys of lupus nephritis patients…
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…
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…
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…
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.”…
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…
Patients who develop neuropsychiatric symptoms of SLE have a small nucleotide polymorphism (SNP) in an intron in a Ca++ ion channel gene that influences some, but not all, events regulated by Ca++. The SNP appears to influence activation induced apoptosis rates and cytokine production, specifically IL-4, in a disease- and genotype-specific manner…
New research used multidomain function assessment to better understand the physical and cognitive functioning of systemic lupus erythematosus (SLE) patients. The pilot study found a high prevalence of impairment in SLE patients, similar to or exceeding the prevalence seen in the general geriatric population. Patients scored lower for lower body strength and low average for cognitive flexibility and attention…
In a long-term extension study, belimumab proved safe, demonstrating low organ damage accrual in SLE patients treated for up to nine years…
Does cognitive dysfunction in SLE patients result from persistent inflammation characterized by ongoing disease activity? Recent research examining this question found no inflammatory mechanism associated with cognitive dysfunction in this patient population, underscoring previous research findings…
