In the 2021 Edmund L. Dubois, MD, Memorial Lectureship, Aimee Hersh, MD, discussed her work on defining research priorities in pediatric lupus.
Rare Disease Sheds Light on the Origins of Lupus
Patients with the rare DNASE1L3 biallelic null mutation present with childhood-onset disease that resembles lupus. This observation prompted research into how abnormalities in the enzyme DNASE1L3 are associated with lupus, with researchers finding autoantibody-mediated impairment of DNASE1L3 activity may be a common non-genetic mechanism leads to anti-dsDNA autoreactivity in SLE.
New Insights into CD8+ T Cells & Lupus
A recent study demonstrated that exposure to type I interferon contributes to the pathogenesis of SLE via the metabolic rewiring of CD8+ T cells, which promotes cell death.
Autoantibodies Against LINE-1 p40 May Be More Common in Patients with Active SLE
Researchers found nearly all systemic lupus erythematosus (SLE) patients have autoantibodies against long interspersed nuclear elements (LINE-1) p40. These findings suggest LINE-1 may be involved in the pathogenesis of SLE.
Familial Patterns in Childhood- & Adult-Onset SLE
A study examining familial patterns of systemic lupus erythematosus (SLE) found a greater decline in SLE recurrence rate by generation in childhood- than in adult-onset SLE, suggesting adult-onset SLE may be characterized by environmental risk factors.
The Environment Within: A Possible Link Identified Between Plasma Microbial Translocation & Autoantibody Development in 1st Degree Relatives of SLE Patients
Plasma microbial translocation, the composition of the microbiome and environmental factors may influence the development of autoantibodies in patients with systemic lupus erythematosus (SLE), according to a study comparing SLE patients with their first-degree relatives and unrelated, healthy controls.
Monthly Belimumab Infusions Preserve Kidney Function in Some Lupus Patients
(Reuters Health)—Intravenous belimumab combined with standard lupus therapy can help preserve kidney function in patients with active lupus nephritis and cut the odds of death or a renal-related event by half, a phase 3 multinational study has concluded.1 After two years of therapy, 43% of 224 volunteers getting the drug monthly showed a renal response…
Can Lupus Be Prevented? Research Reveals Clues to Who’s Most Likely to Transition to Classified Disease
How does a patient transition from health to active SLE? This question is the crux of the research conducted by Judith A. James, MD, PhD, and colleagues…
Renal Transplant Outcomes in Patients with Lupus Nephritis
A recent study from Brazil suggests lupus nephritis patients who receive renal transplant have a high five-year survival rate. Researchers found the presence of venous thrombosis and antiphospholipid syndrome, but not viral infection, were important predictors of renal graft loss in these patients…
Improved Pregnancy Outcomes for Women with SLE
Recent research indicates that previous concerns about mortality associated with pregnancy in women with SLE may no longer be applicable. In the study, researchers found a significant decline in the in-hospital maternal mortality rate of women with SLE and a decrease in their length of non-delivery related hospitalization over the past two decades…
