Noninvasive biomarkers for lupus nephritis

Area of Science:

• Nephrology
• Immunology
• Biomarker Discovery

Background:

• Lupus nephritis (LN) is a severe manifestation of systemic lupus erythematosus (SLE).
• Clinical and histopathological findings in LN can be inconsistent, complicating diagnosis and monitoring.
• Renal biopsy, the current standard, is invasive and carries risks like bleeding and infection.

Purpose of the Study:

• To review discovered biomarkers for lupus nephritis (LN).
• To correlate current knowledge with future perspectives on LN biomarkers.
• To highlight the role of urinary cell phenotype detection in LN diagnosis, monitoring, and treatment.

Main Methods:

• Literature review of existing lupus nephritis biomarkers.
• Analysis of biomarkers reflecting kidney damage and repair processes.
• Focus on urinary cell phenotype detection methods and their utility.

Main Results:

• Numerous LN biomarkers have been identified, reflecting disease pathology.
• Urinary cell phenotype detection shows promise for noninvasive LN assessment.
• Limitations and countermeasures for urinary cell phenotype testing are discussed.

Conclusions:

• Noninvasive biomarkers are crucial for improving LN diagnosis and monitoring.
• Urinary cell phenotype analysis offers a valuable noninvasive approach for LN management.
• Further research is needed to overcome limitations and optimize noninvasive testing for LN.
