Abstract
Although the survival of diabetic peritoneal dialysis (PD) patients has improved, it is still much worse than the survival of nondiabetic patients. Diabetes has its own risks for cardiovascular disease (CVD), such as increased levels of advanced glycation end-products, carbonyl and oxidative stress, and low-grade inflammation. An independent, graded association has been observed between a reduced glomerular filtration rate and the risk of CVD events in chronic kidney disease (CKD). Both CKD and diabetes synergistically lead to a high risk of CVD. It seems that the poor survival of diabetic PD patients is predestined at the initiation of dialysis because of multiple pre-existing risk factors and comorbid diseases, particularly CVD. Recently, several trials were successful in improving the survival of patients with diabetic CKD. Tight control of glucose, blood pressure management using angiotensin converting-enzyme inhibitors or angiotensin II receptor blockers, and use of statins, antioxidants, or peroxisome proliferator-activated receptor gamma agonists may improve the survival of diabetic PD patients. However, simple correction of a single CVD risk factor is not likely to be effective. New PD solutions such as those low in glucose degradation products or those with icodextrin may also be effective in reducing the risk of CVD in diabetic PD patients. Therefore, multifactorial interventions—including diet control, early referral, and choice of an optimal PD solution—may improve the survival of diabetic PD patients.

Abstract
PURPOSE To investigate the effect of pre-dialysis renal care on peritoneal dialysis (PD) patients' outcomes in China. METHODS In this retrospective cohort study, patients who started PD during January 1, 2006, to December 31, 2014, were included. Patients' medical charts were reviewed to extract the information. To explore the effect of pre-dialysis renal care on patients' outcomes, patient were divided into two groups according to whether or not they had frequent renal clinic visits: Group A (with frequent visits) and Group B (without frequent visits). RESULTS A total of 668 patients were included. Patients who admitted to emergency room before PD initiations were significantly higher in Group B than in Group A (42.7 vs. 33 %, p = 0.01). However, there was no significant difference in the proportion of patients requiring emergency hemodialysis prior to PD commencement (20.5 vs. 24.6 %, p = 0.21), acute heart failure (30.2 vs. 35.4 %, p = 0.16) and pulmonary infection (15.4 vs. 12.1 %, p = 0.23) between groups. Both the mortality and technical failure rate in Group A were significantly lower as compared to Group B (p = 0.003 and p < 0.01, respectively). Multivariable Cox regression analysis showed frequent pre-dialysis renal clinic visits were associated with both lower mortality rate (HR 0.62, 95 % CI 0.46-0.85, p = 0.003) and technical failure on PD (HR 0.58, 95 % CI 0.36-0.92, p = 0.022). CONCLUSION Pre-dialysis frequent clinic visits were associated with better PD outcomes. Pre-dialysis renal clinic management was suboptimal in the present cohort. More organized system to ensure people with established chronic kidney disease are well managed is necessary in China.

Abstract
Background The multidisciplinary pre-dialysis education (MPE) retards renal progression, reduce incidence of dialysis and mortality of CKD patients. However, the financial benefit of this intervention on patients starting hemodialysis has not yet been evaluated in prospective and randomized trial. Methods We studied the medical expenditure and utilization incurred in the first 6 months of dialysis initiation in 425 incident hemodialysis patients who were randomized into MPE and non-MPE groups before reaching end-stage renal disease. The content of the MPE was standardized in accordance with the National Kidney Foundation Dialysis Outcomes Quality Initiative guidelines. Results The mean age of study patients was 63.8±13.2 years, and 221 (49.7%) of them were men. The mean serum creatinine level and estimated glomerular filtration rate was 6.1±4.0 mg/dL and 7.6±2.9 mL⋅min−1⋅1.73 m−2, respectively, at dialysis initiation. MPE patients tended to have lower total medical cost in the first 6 months after hemodialysis initiation (9147.6±0.1 USD/patient vs. 11190.6±0.1 USD/patient, p = 0.003), fewer in numbers [0 (1) vs. 1 (2), p<0.001] and length of hospitalization [0 (15) vs. 8 (27) days, p<0.001], and also lower inpatient cost [0 (2617.4) vs. 1559,4 (5019.6) USD/patient, p<0.001] than non-MPE patients, principally owing to reduced cardiovascular hospitalization and vascular access–related surgeries. The decreased inpatient and total medical cost associated with MPE were independent of patients' demographic characteristics, concomitant disease, baseline biochemistry and use of double-lumen catheter at initiation of hemodialysis. Conclusions Participation of multidisciplinary education in pre-dialysis period was independently associated with reduction in the inpatient and total medical expenditures of the first 6 months post-dialysis owing to decreased inpatient service utilization secondary to cardiovascular causes and vascular access–related surgeries.

Abstract
BACKGROUND Early referral of patients with chronic kidney disease (CKD) is believed to help with interventions to address risk factors to slow down the rate of progression of kidney failure to end-stage kidney disease (ESKD) and the need for dialysis, hospitalisation and mortality. OBJECTIVES We sought to evaluate the benefits (reduced hospitalisation and mortality; increased quality of life) and harms (increased hospitalisations and mortality, decreased quality of life) of early versus late referral to specialist nephrology services in CKD patients who are progressing to ESKD and RRT. In this review, referral is defined as the time period between first nephrology evaluation and initiation of dialysis; early referral is more than one to six months, whereas late referral is less than one to six months prior to starting dialysis. All-cause mortality and hospitalisation and quality of life were measured by the visual analogue scale and SF-36. SF-36 and KDQoL are validated measurement instruments for kidney diseases. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2012; Issue 1) which contains the Cochrane Renal Group's Specialised Register; MEDLINE (1966 to February 2012), EMBASE (1980 to February 2012). Search terms were approved by the Trial Search Co-ordinator. SELECTION CRITERIA Randomised controlled trials (RCTs), quasi-RCTs, prospective and retrospective longitudinal cohort studies were eligible for inclusion. DATA COLLECTION AND ANALYSIS Two authors independently assessed study quality and extracted data. Events relating to adverse effects were collected from the studies. MAIN RESULTS No RCTs or quasi-RCTs were identified. There were 40 longitudinal cohort studies providing data on 63,887 participants; 43,209 (68%) who were referred early and 20,678 (32%) referred late.Comparative mortality was higher in patients referred to specialist services late versus those referred early. Risk ratios (RR) for mortality reductions in patients referred early were evident at three months (RR 0.61, 95% CI 0.55 to 0.67; I² = 84%) and remained at five years (RR 0.66, 95% CI 0.60 to 0.71; I² = 87%). Initial hospitalisation was 9.12 days shorter with early referral (95% CI -10.92 to -7.32 days; I² = 82%) compared to late referral. Pooled analysis showed patients referred early were more likely than late referrals to initiate RRT with peritoneal dialysis (RR 1.74, 95% CI 1.64 to 1.84; I² = 92%).Patients referred early were less likely to receive temporary vascular access (RR 0.47, 95% CL 0.45 to 0.50; I² = 97%) than those referred late. Patients referred early were more likely to receive permanent vascular access (RR 3.22, 95% CI 2.92 to 3.55; I² = 97%). Systolic blood pressure (BP) was significantly lower in early versus late referrals (MD -3.09 mm Hg, 95% CI -5.23 to -0.95; I² = 85%); diastolic BP was significantly lower in early versus late referrals (MD -1.64 mm Hg, 95% CI -2.77 to -0.51; I² = 82%). EPO use was significantly higher in those referred early (RR 2.92, 95% CI 2.42 to 3.52; I² = 0%). eGFR was higher in early referrals (MD 0.42 mL/min/1.73 m², 95% CI 0.28 to 0.56; I² = 95%). Diabetes prevalence was similar in patients referred early and late (RR 1.05, 95% CI 0.96 to 1.15; I² = 87%) as was ischaemic heart disease (RR 1.05, 95% CI 0.97 to 1.13; I² = 74%), peripheral vascular disease (RR 0.99, 95% CI 0.84 to 1.17; I² = 90%), and congestive heart failure (RR 1.00, 95% CI 0.86 to 1.15; I² = 92%). Inability to walk was less prevalent in early referrals (RR 0.66, 95% CI 0.51 to 0.86). Prevalence of chronic obstructive pulmonary disease was similar in those referred early and late (RR 0.89, 95% CI 0.70 to 1.14; I² = 94%) as was cerebrovascular disease (RR 0.90, 95% CI 0.74 to 1.11; I² = 83%).The quality of the included studies was assessed as being low to moderate based on the Newcastle-Ottawa Scale. Slight differences in the definition of early versus late referral infer some risk of bias. Generally, heterogeneity in most of the analyses was high. AUTHORS' CONCLUSIONS Our analysis showed reduced mortality and mortality and hospitalisation, better uptake of peritoneal dialysis and earlier placement of arteriovenous fistulae for patients with chronic kidney disease who were referred early to a nephrologist. Differences in mortality and hospitalisation data between the two groups were not explained by differences in prevalence of comorbid disease or serum phosphate. However, early referral was associated with better preparation and placement of dialysis access.

Abstract
BACKGROUND Diabetes mellitus (DM)-associated chronic kidney disease (diabetic renal disease) became the predominant etiology of the end-stage renal disease (ESRD) in the western countries and shows the same trend in the developing countries. Early mortality (EM) after the dialysis initiation, defined as death of all causes within the first 3 months after initiation of renal replacement therapy (RRT), is of concern especially for the high-risk renal patients including diabetics. The goal of the present study was to identify demographic and clinical risk factors associated with EM in a retrospective cohort of Romanian DM patients initiated on dialysis. METHODS A retrospective case-control study was designed. Clinical recordings from all patients initiated on hemodialysis (HD) or peritoneal dialysis between January 1996 and December 2005 in the Dialysis Center of NIDNMD Paulescu, Bucharest, were collected and analyzed. Patients were classified accordingly in two groups: those who displayed EM formed the "cases" group, while the others were included in the "controls" group. Both univariate (subgroup analysis) and multivariate analyses (logistic regression, Cox regression) were used to analyze the impact of risk factors on EM outcome. RESULTS Data from 788 patients were included in the analysis. The factors significantly associated with EM in the univariate analysis were female gender, late initiation (LI) of dialysis, old age and HD used as the first/only method. Applying the multivariate analysis, only the use of HD (OR = 4.20, p < 0.0001) and the LI of dialysis (p < 0.0001; 95 % CI 1.36-2.30) were associated with EM, while female gender showed only a trend to a higher EM (OR = 1.29, p = 0.052). CONCLUSIONS Hemodialysis used as a first/single method for RRT and the LI of dialysis were independent predictors of EM in our ESRD diabetic patients. A possible explanation for the first factor could be our specific center procedure, which allows only the HD as rescue therapy method for the most severe cases, managed in the intensive care unit.

Abstract
Peritoneal dialysis (PD) has become an established dialysis modality besides hemodialysis (HD). Although PD is an equal form of dialysis compared to HD, patients numbers on PD remain low worldwide. There are several reasons for this fact. The medical staff in some centers is not used to PD, so there is not enough information about the different dialysis methods available for the patients and the staff doesn't get the training that would be necessary to get familiar with PD. There are some concerns about offering PD to certain groups of patients despite excellent results as to quality of dialysis, good preservation of residual renal function, low costs compared to HD and better quality of life than on HD. However, PD should be offered to all patients requiring dialysis with very few exeptions as an ideal initial dialysis method. This includes patients with diabetes, patients with kidney transplant failure, patients with congestive heart failure and older patients.

Abstract
End stage renal disease diabetic patients suffer from worse clinical outcomes under dialysis-independently of modality. Peritoneal dialysis offers them the advantages of home therapy while sparing their frail vascular capital and preserving residual renal function. Other benefits and potential risks deserve discussion. Predialysis intervention with early nephrology referral, patient education, and multidisciplinary support are recommended. Skilled and updated peritoneal dialysis protocols must be prescribed to assure better survival. Optimized volume control, glucose-sparing peritoneal dialysis regimens, and elective use of icodextrin are key therapy strategies. Nutritional evaluation and support, preferential use of low-glucose degradation products solutions, and prescription of renin-angiotensin-aldosterone system acting drugs should also be part of the panel to improve diabetic care under peritoneal dialysis.

Abstract
BACKGROUND In the U.S. Renal Data System registry, technique and patient survival are similar with automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD). The clinical outcomes of APD and CAPD in various age groups have not been clarified. OBJECTIVES We investigated whether patient and technique survival are different for incident dialysis patients treated with APD or CAPD in two age groups. METHODS Our retrospective study of prospectively collected data included 282 incident peritoneal dialysis (PD) patients (161 on APD, 121 on CAPD). Patients on PD for less than 3 months were excluded. The patients were divided into those less than 65 years of age and those 65 years of age or older. Overall mortality and technique failure were the primary endpoints of the study. Hazard ratios (HRs) for mortality and technique failure were calculated by the Cox proportional hazards model and were adjusted for age, sex, diabetes mellitus, initial peritoneal equilibration test (PET), weekly peritoneal and renal creatinine clearances, and PD caregiver (self or other). RESULTS The characteristics and clinical data were not significantly different between patients on APD and CAPD, except for age and sex. The adjusted risk for overall mortality was not different between patients on APD and CAPD (HR: 0.72; 95% CI: 0.44 to 1.20; p = 0.207). The adjusted risk for technique failure was lower in APD patients than in CAPD patients (HR: 0.58; 95% CI: 0.34 to 0.98; p = 0.041). In patients less than 65 years of age, those on APD had a significantly lower risk of mortality (HR: 0.35; 95% CI: 0.16 to 0.75; p = 0.007) and technique failure (HR: 0.52; 95% CI: 0.28 to 0.95; p = 0.034) than did those on CAPD. In patients 65 years of age and older, those on APD had risks for mortality (HR: 1.14; 95% CI: 0.53 to 2.46; p = 0.730) and technique failure (HR: 0.51; 95% CI: 0.17 to 1.50; p = 0.220) that were similar to those of patients on CAPD. Nutrition status, including serum albumin and protein catabolic rate, was not significantly different between patients on APD and on CAPD, in either younger or older patients. CONCLUSIONS Younger Chinese patients on APD have better patient and technique survival than do those on CAPD. However, there is a strong possibility that this benefit may be confounded or accounted for by baseline differences between the APD and CAPD populations.

Abstract
BACKGROUND The use of peritoneal dialysis (PD) has been declining over the past decade in Canada, and high technique failure rates have been implicated. Studies have examined clinical risk factors for PD technique failure, but few studies have addressed sociodemographic factors driving technique failure. There are no studies examining the effect of physician factors on technique failure. METHODS We conducted a retrospective cohort study using Ontario healthcare databases from 1 April 1995 to 31 March 2005 to examine the effects of patient sociodemographic and physician characteristics on PD technique failure. The primary outcome was time to technique failure. Secondary outcomes included the proportion of patients experiencing technique failure during the first year and the proportion of patients experiencing death during the study period. A competing risks analysis was applied to the Cox proportional hazards model to determine the predictors of technique failure, death, and kidney transplantation. RESULTS In 5162 incident PD patients, the probability of technique success and patient survival at 5 years was 58.2% and 46.9% respectively. Of patients failing PD, 43.5% failed during the first year of treatment. Statistically significant predictors of technique failure included increasing age [hazard ratio (HR) 1.02], diabetes mellitus (HR 1.32), lower neighborhood education level (HR 2.93), and receiving transient (≤ 3 months) hemodialysis before starting PD (HR 1.24). Predictors of patient death included increasing age (HR 1.05), diabetes mellitus (HR 1.44), coronary artery disease (HR 1.26), congestive heart failure (HR 1.58), and late referral to the nephrologist (HR 1.27). Distance from treating dialysis center and residing in a rural area did not impact the risk of technique failure or death. Male physician gender increased the risk of technique failure (HR 1.31). Increased PD patient volume decreased the risk of technique failure (HR 0.98). None of the physician factors were predictors of patient death. CONCLUSION These findings support the need for implementing strategies to reduce technique failure, which could include increasing educational resources for patients initiating PD, aggressive risk factor modification in patients with multiple comorbidities, and increasing physician awareness regarding the detrimental outcomes associated with late referral and late PD start.

Abstract
BACKGROUND Observational studies have demonstrated that multidisciplinary predialysis education (MPE) improves the post-dialysis outcomes of chronic kidney disease (CKD) patients. However, the beneficial effect of MPE remains unclear in prospective controlled studies. METHODS All CKD patients who visited the outpatient nephrology clinics at two centres of the Chang Gung Memorial Hospital in 2006-07 were enrolled. The incidence of dialysis and mortality were compared between MPE recipients and non-recipients. The content of the MPE was standardized in accordance with the NKF/DOQI guidelines. Prognostic factors for progression to end-stage renal disease (ESRD) and all-cause mortality were analysed by using the Cox proportional hazards model. RESULTS Of 573 patients, 287 received MPE. Dialysis was initiated in 13.9% and 43% of the patients in the MPE and non-MPE groups, respectively (P < 0.001). The mean follow-up period was 11.7 +/- 0.9 months. The overall mortality was 1.7% and 10.1% in the MPE and non-MPE groups, respectively (P < 0.001). Cox regression analysis revealed that diabetes, estimated glomerular filtration rate (eGFR), high-sensitive C-reactive protein (hs-CRP) and MPE assignment were significant independent predictors for progression to ESRD. Independent prognostic factors for mortality included age, diabetes, eGFR, hs-CRP and MPE assignment. CONCLUSIONS MPE based on the NKF/DOQI guidelines may decrease the incidence of dialysis and reduce mortality in late-stage CKD patients.

Abstract
The population of elderly patients entering chronic dialysis programmes is increasing. Elderly patients are susceptible to malnutrition and have multiple complicating disorders in addition to uraemia. Selecting appropriate dialysis modality is particularly critical in elderly patients. Continuous ambulatory peritoneal dialysis (CAPD) has many advantages to elderly patients; however, the clinical outcome varies for elderly CAPD patients. In comparison with Westerners, Southeast Asians have a small body mass index and may be more suited to CAPD therapy. To identify the prognostic predictors in elderly Southeast Asian patients, this historical cohort study analysed 144 patients aged > or = 65 years at initiation of CAPD. A group of haemodialysis (HD) patients aged > or = 65 years was utilised as the control group. Survival curves for patient and technique were derived from Kaplan-Meier analysis and were further analysed by Cox-Mantel log-rank test. To elucidate the impact of individual factors on patient survival, various significant univariables were further subjected to multivariate analysis. No significant increase existed for relative risk of technique failure in elderly patients compared with younger patients. This analytical data indicates that CAPD was as good as HD for elderly uraemic patients regarding to the patient survival. Diabetes, dependent patients, low albumin levels and previous HD history were significant poor prognostic factors for survival of elderly CAPD patients. In conclusion, CAPD is an effective modality of renal replacement therapy for Southeast Asian elderly patients. The technique survival was not affected by patient age.

Abstract
OBJECTIVES To evaluate the influence of early nephrology referral on clinical outcome in patients on maintenance hemodialysis (HD) and peritoneal dialysis (PD). PATIENTS AND METHODS This study retrospectively analyzed patients entering our HD and PD program from February 2000 to June 2003. Patients who presented to a nephrologist more than 6 months before starting dialysis were defined as early referral (ER). Meanwhile, patients transferred to the nephrology department less than 6 months before initial dialysis were considered late referral (LR). RESULTS HD GROUPS: Of 78 HD patients, 37 (47.1%) qualified for the ER group and 41 (52.6%) were designated to the LR group. The demographic data were analyzed for both the HD and PD groups. No significant differences in average age at dialysis, duration of hemodialysis, and gender were noted between these two groups. The same applied for the biochemical parameters in both groups. HD patients with early referral had significantly better survival (p < .05) as plotted with the Kaplan-Meier method. In univariate analysis by cox proportional hazards mode, the early referral in HD patients [Exp (Coef) = 0.426, P < .01] significantly influenced survival. The various variables were further examined by multivariate analysis, and early referral, hemoglobin, and age still significantly impacted patient survival (P < .05). CAPD GROUPS: The survival curve related to early referral in continuous ambulatory peritoneal dialysis (CADP) patient survival rate was significantly higher for the early referral groups (P < .05). In addition, a multivariate analysis adjusting for several potential risk factors found that referral time remained significantly associated with patient survival. In additional, hemoglobin and age were significant and independent predictors of mortality. CONCLUSION This study demonstrates that time between referral and starting dialysis is a predictor of survival for both HD and PD patients, with early referral being associated with longer survival time. These analytical results suggest that early referral before dialysis is important in determining long-term prognosis in HD and PD patients.
