Longevity & AgingWhy childhood-onset lupus hits harder and what a decade of research reveals
Childhood-onset systemic lupus erythematosus (SLE) tends to be more severe than adult-onset disease. It brings more active disease, higher cardiovascular risk, earlier organ damage (kidney, brain, nervous system, and musculoskeletal), and heavier use of steroids and immunosuppressants. Yet its underlying biology is far less understood. This review from Nature Reviews Rheumatology summarizes progress from the past decade, driven by new technologies that profile immune, genetic, epigenetic, metabolic, and protein signatures in young patients. The authors highlight immune dysregulation, interferon signaling, and the influence of biological sex, gender, and ethnicity in shaping how the disease varies between patients. Together, these insights help explain why childhood-onset SLE is so aggressive and suggest new routes toward personalized treatment aimed at protecting long-term health and quality of life. This summary is based on the abstract only.
