Lupus nephritis is a kidney inflammation caused by systemic lupus erythematosus (SLE), an autoimmune disease in which the body’s immune system attacks its own tissues. In lupus nephritis, immune complexes (antibodies bound to antigens) deposit in the glomeruli, causing inflammation, scarring, and impaired kidney function.
It can affect both children and adults with SLE and varies widely in severity — from mild, asymptomatic kidney involvement to rapidly progressive kidney failure. Early detection and treatment are critical to prevent permanent kidney damage.
Is it common?
Lupus nephritis occurs in approximately 30–60% of individuals with systemic lupus, depending on age, sex, and ethnicity. It is more common in women and people of African, Hispanic, or Asian descent. Kidney involvement often develops within the first few years after SLE diagnosis but can occur at any time.
Can it be cured?
There is no cure for lupus nephritis or systemic lupus, but treatment can control inflammation, reduce proteinuria, preserve kidney function, and prevent flares. Long-term monitoring is essential to detect disease activity early and adjust therapy. Some patients may achieve remission, while others may progress to chronic kidney disease.
