Abstract:

Lupus nephritis (LN) is one of the most common and serious manifestations of systemic lupus erythematosus (SLE). Kidney damage occurs in 20% to 60% of patients with SLE. As traditional biomarkers for LN diagnosis, anti-double-stranded DNA antibodies, complement components C3 and C4, and urine protein-creatinine ratio, etc., lack specificity and sensitivity in monitoring disease activity and early renal pathological damage. The gold standard for LN diagnosis is pathological biopsy of renal tissue, which is an invasive examination that is not suitable for early diagnosis and repeated monitoring. Finding novel biomarkers that can replace renal biopsy is of great significance for early diagnosis, monitoring of disease activity, and improving prognosis. This paper summarized the research progress for novel biomarkers in blood and urine, and put forward the prospect of their clinical application, providing theoretical support for clinical diagnosis.

Key words: Lupus nephritis, Novel biomarkers, Traditional biomarkers, Blood, Urine
