BACKGROUND Prevention or reversal of peritoneal damage is critical in peritoneal dialysis. Although autologous cell transplantation has beneficial effects on tissue repair in various organs, few studies have investigated the effects of transplantation of adipose-derived mesenchymal stem cells (ASCs) on peritoneal fibrosis (PF). Thus, we examined the(More)
It is well known that bioincompatible peritoneal dialysate plays a central role in the development of peritoneal fibrosis. Peritoneal inflammation continues even after the cessation of peritoneal dialysate stimulation. It is important to establish the definition of persistent inflammation in the peritoneal cavity at the cessation of peritoneal dialysis(More)
INTRODUCTION AND OBJECTIVE While pruritus is a common complication in hemodialysis patients, the pathophysiological mechanisms remain obscure. Recently, B-type (brain) natriuretic peptide (BNP) has been defined as an itch-selective neuropeptide in pruriceptive neurons in mice, and higher serum levels of BNP are frequently observed in hemodialysis patients.(More)
BACKGROUND The prevention and restoration of peritoneal damage is a critical mission in peritoneal dialysis (PD). Transplantation of mesothelial cells has been suggested to suppress peritoneal injury during PD. Few studies have examined the efficacy and safety of cell transplantation. We evaluated the paracrine effects of mesothelial transplantation during(More)
Peritoneal dialysis (PD) catheters often become severely dislocated, which may lead to malfunction. With the aim of preventing this complication, we have developed a simple method of fixing the catheter downwards in the peritoneal cavity (fixation technique), a technique that does not require a laparoscope. Sixteen patients were implanted using the(More)
BACKGROUND Preventing peritoneal damage during peritoneal dialysis is critical. Reactive oxygen species (ROS) have an important role in peritoneal damage; however, few studies have investigated this. We aimed to determine the effects of oral astaxanthin (AST) supplementation in a peritoneal fibrosis (PF) rat model. METHODS Thirty-seven Sprague-Dawley rats(More)
It is well known that a combination therapy with peritoneal dialysis (PD) and hemodialysis (HD) is feasible and may improve clinical status in patients for whom adequate solute and fluid removal is difficult to achieve with PD alone. The objective of the present study was to evaluate whether the therapy is useful in the likelihood of long-term peritoneal(More)
BACKGROUND High glucose concentrations influence the functional and structural development of the peritoneal membrane. We previously reported that the oral administration of astaxanthin (AST) suppressed peritoneal fibrosis (PF) as well as inhibited oxidative stress, inflammation, and epithelial-mesenchymal transition (EMT) of peritoneal mesothelial cells(More)
BACKGROUND Although ultrasonography before a vascular access (VA) operation has become popular in recent years, benchmarks for the diameter or blood flow of arteries or veins are not defined in Japan. The objective of the present study is to analyze the relationship between preoperative US findings and the patency rate of VA in Japanese hemodialysis(More)
