    In dialysis patients, physical function is associated with mortality. However, the association between physical function at the time of dialysis initiation and subsequent mortality remains unknown. A total of 1496 patients with chronic kidney disease who initiated dialysis at 17 centers participating in the Aichi Cohort Study of the Prognosis in Patients Newly Initiated into Dialysis, a multicenter prospective cohort study, were included. The patients were divided into the high (H)-, middle (M)-, and low (L)-score groups according to Barthel index (BI) at the time of dialysis initiation, and the all-cause, cardiovascular disease (CVD)-related, and infection-related mortality rates were compared. Moreover, factors affecting all-cause mortality were investigated. The effects of BI on mortality were assessed in the patients stratified by age, sex, and history of CVD or cerebral infarction. A log-rank test for the Kaplan-Meier survival curve showed significant differences between the three groups in all-cause, CVD-related, and infection-related mortality rates (p < 0.001). Cox proportional hazard regression analysis with the step-wise method showed a significantly higher risk of all-cause mortality in the M and L groups than in the H group (M group: HR 1.612, 95 % CI 1.075-2.417; L group: HR 1.994, 95 % CI 1.468-2.709). Regardless of the age categories and the history of CVD, the risk of all-cause mortality was significantly higher in the L group than in the H group. Physical function assessed by BI at the time of dialysis initiation was found to be associated with subsequent mortality.

    Chronic kidney disease (CKD) eventually progresses to end-stage renal disease (ESRD). However, risk factors associated with CKD progression have not been well characterized in Japanese patients with CKD who are less affected with coronary disease than Westerners. A large-scale, multicenter, prospective, cohort study was conducted in patients with CKD and under nephrology care, who met the eligibility criteria [Japanese; age 20-75 years; and estimated glomerular filtration rate (eGFR): 10-59 mL/min/1.73 m(2)]. The primary endpoint was a composite of time to a 50 % decline in eGFR from baseline or time to the initiation of renal replacement therapy (RRT). The secondary endpoints were the rate of decline in eGFR from baseline, time to a 50 % decline in eGFR from baseline, time to the initiation of RRT, and time to doubling of serum creatinine (Cre) concentration. 2966 patients (female, 38.9 %; age, 60. 3 +/- 11.6 years) were enrolled. The incidence of the primary endpoint increased significantly (P < 0.0001) in concert with CKD stage at baseline. The multivariate Cox proportional hazards models revealed that elevated systolic blood pressure (SBP) [hazard ratio (HR) 1.203, 95 % confidence interval (CI) 1.099-1.318)] and increased albumin-to-creatinine ratio (UACR >= 1000 mg/g Cre; HR: 4.523; 95 % CI 3.098-6.604) at baseline were significantly associated (P < 0.0001, respectively) with the primary endpoint. Elevated SBP and increased UACR were risk factors that were significantly associated with CKD progression to ESRD in Japanese patients under nephrology care.

    Over 300,000 patients receive maintenance dialysis in Japan; managing these patients is extremely important. This study aimed to report on prior management of chronic kidney diseases and prognostication after dialysis initiation. Seventeen institutions participated in the Aichi cohort study of prognosis in patients newly initiated into dialysis and recruited patients over a period of 2 years. Exclusion criteria were (1) patients under 20 years; (2) patients who died before hospital discharge; and (3) patients who could not provide consent. Here, we showed data on dialysis initiation time. Of 1524 patients with mean age of 67.5 +/- 13.0 years, 659 patients were put on dialysis following diabetic nephropathy diagnosis. At dialysis initiation time, creatinine and estimated glomerular filtration rate levels were 8.97 +/- 3.21 mg/dl and 5.45 +/- 2.22 ml/min/1.73 m(2), respectively. Medications taken were angiotensin II receptor blockers in 866; angiotensin-converting enzyme inhibitors in 135; calcium antagonist in 1202; and diuretics, alone or in combination, in 1059. Among patients with diabetic nephropathy, many had increased body weight and systolic blood pressure and were taking loop and thiazide diuretics at dialysis initiation time. Many patients with diabetic nephropathy had coronary artery disease and percutaneous coronary intervention. Many patients with diabetic nephropathy who registered for this study had coronary artery disease and problems with excess body fluid. Further analyses may clarify how underlying conditions and disease management before and after dialysis initiation affect prognosis.

    Background: Death in dialysis patients results mainly from cardiovascular and cerebrovascular diseases. To our knowledge, no prospective study has compared the rates of mortality or cardiovascular events between patients with and without atrial fibrillation (AF) at the time of dialysis initiation. Methods: This study included 1,516 patients who were initiated into dialysis between October 2011 and August 2013. Rates of mortality and cardiovascular events were compared between patients with and without AF, and between AF patients with and without warfarin (WF) treatment. Results: The study comprised 1,025 men and 491 women with a mean age of 67.5 +/- 13.1. Of these patients, 93 had AF, while 1,423 did not; 22.6% of the former group and 9.7% of the latter group died by March 2014 (p < 0.01). Cardiovascular events occurred in 34.4% of patients with AF and 15.1% of patients without (p < 0.01). Even after adjustments for various factors, AF remained an independent risk factor for mortality (hazard ratio (HR) 1.873, 95% CI 1.168-3.002, p < 0.01). It was also an independent risk factor for cardiovascular events (HR 1.872, 95% CI 1.262-2.778, p < 0.01). No difference in any parameter was noted between the groups that did and did not receive WF treatment. Conclusion: Patients with AF at the time of dialysis initiation show a poor prognosis and are at high risk of cardiovascular events. Therefore, AF should be taken into consideration in dialysis patients. (C) 2016 S. Karger AG, Basel
