Urine Exosomes to Identify Biomarkers for LN

RenJi Hospital400 enrolled

Overview

Urine exosomes will be extracted from patients with lupus nephritis, healthy controls, and patients with systemic lupus erythematosus without lupus nephritis. Transcriptome and/or metabonomics sequencing of exosomes will be performed to screen for molecules in the urine exosomes of patients with lupus nephritis that are significantly different from those of the other groups.

Lupus nephritis is one of the most common complications of SLE, and its severity is closely related to the prognosis of SLE. The gold standard for diagnosing lupus nephritis depends on the pathological results of a kidney biopsy, which is invasive and may cause some damage to the patient. Exosomes exist in almost all types of body fluids such as serum, urine and cerebrospinal fluid, and contain a variety of genetic materials and proteins secreted by cells, such as miRNA, lnRNA, cirRNA and metabolites, etc., which are potential substances that can be used as biomarkers of diseases discovered in recent years. Urine exosomes are easy to obtain and have no impact on patients' health, making them suitable for study as disease biomarkers for lupus nephritis. In this study, urine exosomes will be extracted from patients with lupus nephritis, healthy controls, and patients with systemic lupus erythematosus without lupus nephritis. Transcriptome and/or metabonomics sequencing of exosomes will be performed to screen for molecules in the urine exosomes of patients with lupus nephritis that are significantly different from those of the other groups.

Outcomes

Primary Outcomes

specific molecule levels in urine exosomes

Molecule like miRNAs were determined in urine exosomes of different groups and the following validation will determine which molecule can be served as biomarkers of lupus nephritis
