Background Approximately 20% of patients on peritoneal dialysis (PD) in Japan are on combination with once-weekly haemodialysis (HD). This study aimed to compare outcomes of combination therapy and PD alone. Methods This longitudinal study on the Japanese Renal Data Registry included patients on PD from 2010 to 2014. Subjects were followed until the end of 2015. Exposure of interest was combination therapy compared with PD alone. Outcomes were complete transition to HD, all-cause mortality, card...

Background:Unlike the situation in the general population, most studies of patients receiving hemodialysis have reported lower uric acid (UA) as associated with higher mortality. However, the relat...

Introduction Previous studies showed that the combination of peritoneal dialysis (PD) and once-weekly hemodialysis is associated with lower all-cause and cardiovascular mortality. This study aimed to compare the incidence of encapsulating peritoneal sclerosis (EPS) and infection-related mortality among those on combination therapy and those on PD alone. Methods This prospective study on the Japanese Renal Data Registry included patients on PD from 2010 to 2014. Subjects were followed up until th...

BACKGROUND The prevalence and severity of anemia differ between diabetic and non-diabetic patients. We investigated whether the effect of hemoglobin (Hb) on patient outcome was affected by the presence or absence of diabetes among Japanese patients receiving chronic hemodialysis (HD). METHODS We enrolled 149,308 patients from a nationwide dialysis registry in Japan at the end of 2012 (mean age, 67.6 ± 12.3 years; male, 61.7%; diabetes, 43.5%; median dialysis duration, 65 months) who underwent th...

Background Previous studies have shown that hyponatremia is associated with greater mortality in hemodialysis (HD) patients. However, there have been few reports regarding the importance of the change in serum sodium (SNa) concentration (ΔSNa) during dialysis sessions. To investigate the relationships of pre-dialysis hyponatremia and ΔSNa during a dialysis session with mortality, we analyzed data from a national registry of Japanese patients with end-stage kidney disease. Methods We identified 1...

Background Although a substantial number of patients return to dialysis after kidney transplant failure, it remains controversial whether transplant-failure patients have a higher mortality risk than transplant-naive patients on dialysis who have never undergone kidney transplantation. We compared outcomes of transplant-failure and transplant-naive patients on hemodialysis. Methods Data from the Japanese National Dialysis Registry (2012-2013) were analyzed, including 220,438 prevalent hemodialys...

The association of glycated albumin (GA) with mortality is unclear in chronic hemodialysis patients with diabetes. We investigated the usefulness of GA by comparing it with hemoglobin A1c (HbA1c) in this patient population. This was a multi-center, prospective cohort study of 841 Japanese chronic hemodialysis patients with diabetes. There were 235 women and 606 men included, with a mean age of 64 years. The primary and secondary endpoints were the incidence of all-cause and cause-specific mortal...

The annual survey questionnaires of the Japanese Society for Dialysis Therapy Renal Data Registry (JRDR) were sent to 4458 dialysis facilities at the end of 2018; 4402 facilities (98.7%) responded to the facility questionnaire, and 4222 facilities (94.7%) responded to the patient questionnaire. This paper reports the results obtained in regard to several issues: dialysis fluid quality, prescription of hemodialysis and hemodiafiltration, current status of peritoneal dialysis, and glycemic indices...

Introduction Differences in mortality and cause-specific mortality rates according to glycated albumin (GA) and hemoglobin A1c (HbA1c) levels among dialysis patients with diabetes based on hypoglycemic agent use and malnutrition status remain unclear. Here, we examine these associations using a nationwide cohort. Research design and methods We examined 40 417 dialysis patients with diabetes who met our inclusion criteria (female, 30.8%; mean age, 67.3±11.2 years; mean dialysis duration, 5.4±4.6 ...
