Peritoneal dialysis effluent-derived exosomal miR-432-5p: an assessment tool for peritoneal dialysis efficacy.

ABSTRACT:

Background

Ultrafiltration (UF) volume and peritoneal solute transport rate (PSTR) are common parameters used to evaluate the efficacy of peritoneal dialysis (PD) on individual patients. It is unclear whether the level of exosomal microRNA (miRNA) in peritoneal dialysis effluent (PDE) can predict UF or PSTR. This study was designed to investigate if there is a correlation between PDE exosomal miRNA (miR-432-5p) levels and various UF volumes and PSTRs in PD patients. It also aimed to explore the underlying mechanism of water and dialytic sodium removal (DSR).

Methods

The PSTR was quantified using the 4-hour (4 h) 3.86% dialysate to plasma creatinine ratio. The PDE exosomes (PDE-exo) were isolated by ultracentrifugation. An miRNA assay was used to identify the different miRNA
