Malnutrition that is associated with inflammation is a key factor of poor outcome in chronic hemodialysis patients, especially in older dialysis patients. Polymethyl methacrylate (PMMA) membrane has been reported to improve the inflammatory status by removing pro-inflammatory cytokines via adsorption. However, older dialysis patients occasionally have multiple uncomfortable dialysis-related symptoms, which decrease their quality of life and survival rate. We investigated whether a new PMMA membr...

According to the annual survey of the Japanese Society for Dialysis Therapy Renal Data Registry (JRDR) conducted at the end of 2018, there were a total of 339,841 patients receiving dialysis (hereinafter, dialysis patients) in Japan. The survey included questions regarding the presence/absence of dementia, the performance status (PS), and the exercise habits of individual patients. The survey revealed that 10.8% of all dialysis patients had dementia (1.8% in the age group of less than 65 years, ...

According to the annual survey of the Japanese Society for Dialysis Therapy Renal Data Registry (JRDR) conducted at the end of 2018, a total of 339,841 patients were receiving dialysis (hereinafter, dialysis patients) in Japan. This survey included an investigation of individual test results for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody (HCV-Ab), HCV-RNA, and serum alanine aminotransferase (ALT) (glutamic pyruvic transaminase [GPT]). The survey revealed that among dia...

Background: Dialyzers are classified as low-, high-, and super high-flux membrane dialyzers internationally and as types I, II, III, IV, and V based on β2-microglobulin clearance rate in Japan. Type I dialyzers correspond to low-flux membrane dialyzers, types II and III to high-flux, and types IV and V to super high-flux. Here we aimed to clarify the association of dialyzer type with mortality. Methods: This nationwide prospective cohort study analyzed data from the Japanese Society for Dialysis...

Introduction null The study aimed to verify the impact of our clinical strategy, which emphasizes patient-centered care, based on patient-reported outcome measures (PROMs) results in hemodialysis patients. null Methods null We developed our original PROM (comprising 20 items) to assess patients' symptom burden. To confirm the validity of our clinical pattern, we performed various analyses using PROM data. null Results null We retrospectively enrolled 383 individuals (mean age 66.3 years; 252 men...

Few data are available regarding the association of dialyzer type with prognosis. In Japan, dialyzers are classified as types I, II, III, IV, and V based on β2-microglobulin clearance rates of < 10, < 30, < 50, < 70, and ≥ 70 mL/min, respectively. We investigated the relationship of the 5 dialyzer types with 1-year mortality. This nationwide cohort study used data collected at the end of 2008 and 2009 by the Japanese Society for Dialysis Therapy Renal Data Registry. We enrolled 203,008 patients ...

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...
