Abstract:Peritoneal dialysis (PD) is one of the main treatment methods for patients with end-stage renal disease. It has a wide application prospect due to its advantages of better protection of residual renal function. However, long-term PD is prone to multiple complications, of which peritoneal dialysis-related peritonitis is one of the most common complications. Repeated inflammatory stimuli will accelerate the development of peritoneal fibrosis and eventually lead to ultrafiltration failure and peritoneal dialysis disfunction. MicroRNA (miRNA) are one of the non-coding RNA, and their role in inflammation and fibrosis has attracted much attention. Studies have shown that numerous miRNA are involved in peritoneal inflammation and fibrosis. Recent studies have shown that the expression profile of a variety of miRNA changes during peritoneal dialysis. This article reviews the research progress of miRNAs in peritoneal dialysis.
