Monitoring Lupus Nephritis Through Urinary Extracellular Vesicles
NCT06642402
Summary
Lupus nephritis (LN) is a severe manifestation of systemic lupus erythematosus (SLE) that can lead to irreversible kidney damage if not detected and managed promptly. LN is classified and treated based on its histopathological features obtained by invasive kidney biopsy. Recent research has suggested urinary extracellular vesicles (uEVs) as potential non-invasive biomarkers. The primary objective of this prospective study is to investigate the utility of uEVs in LN.
