Abstract Background and Aims Incremental Peritoneal Dialysis (IPD) is the practice of initiating PD exchange less than four times a day in consideration of residual renal function (RRF). More clinical studies have confirmed the feasibility and effectiveness of IPD, especially in the protection of residual renal function, which is obviously superior to full-dose PD. Urgent-start peritoneal dialysis (USPD) is a popular PD method. Due to lack of pre-dialysis education, most of patients who were newly diagnosed with ESRD in China chose USPD. Well, can incremental peritoneal dialysis be used for USPD patients when starting dialysis? Compared to full-dose PD, whether incremental PD affects the residual renal function in USPD patients? Here we report the first study of incremental peritoneal dialysis’s effect on residual renal function. Method A retrospective analysis of medical records was performed on 169 patients who received USPD from August 2008 to March 2017. Patients were divided into 2 groups according to dialysis dose: incremental PD(i-PD) group (dialysis dose were less than or equal to 6000ml or 3 exchanges per day) and full-dose PD(f-PD) group (dialysis dose were great than or equal to 8000ml or 4 exchanges per day). The demographics, clinical biochemical indexes, dialysis dose, urine volume, dialysis ultrafiltration volume, RRF, dialysis adequacy, peritoneal dialysis infection complications, mechanical complications and survival rates were compared between two groups in 1 year follow-up. Results: (1).A total of 169 patients were enrolled, including 111 patients (average age 45.01±12.84 years) in i-PD group and 58 patients (average age 43.5±15.62 years) in f-PD group. The demographics and clinical biochemical indexes in the two groups before peritoneal dialysis were similar (P>0.05). (2).During the follow-up period, the dialysis dose in f-PD group(8034.48±262.61ml/d, 8080.00±395.80ml/d, 8155.17±523.21ml/d, 8051.72±906.55ml/d) were more than those in i-PD group(5891.89±528.31ml/d, 6159.57±1185.06ml/d, 6468.47±1588.71ml/d, 6900.90±1543.05ml/d), P<0.05. And the dialysis adequacy in both groups were up to standard: the total Kt/V (i-PD group: 1.96±0.56, 2.01±0.70, 2.02±0.55, 1.90±0.52; f-PD group: 2.18±0.47, 2.22±0.55, 2.05±0.44, 2.03±0.42) were greater than 1.7 and the total Ccr (i-PD group: 79.39±29.75, 79.02±25.11, 78.26±30.00, 73.09±29.14; f-PD group: 89.78±29.89, 91.54±35.56, 82.38±29.27, 72.96±23.75) were greater than 60L. (3).During the whole follow-up period, the residual renal function between two groups had no statistically significant(i-PD group: 3.96±2.52ml/min, 3.46±1.95ml/min, 3.58±2.85ml/min, 2.91±2.33ml/min; f-PD group: 4.31±4.83ml/min, 3.45±2.36ml/min, 3.16±2.15ml/min, 2.36±1.65ml/min), P>0.05. (4).During the whole follow-up period, the blood pressure control, correction of anemia, and correction of calcium and phosphorus abnormalities were also similar in both groups, P>0.05. (5).At 1-month and 6-month, the urine volume were higher in i-PD group(1024.33±492.91ml/d, 1017.03±571.66ml/d) than those in f-PD group(782.93±415.89ml/d, 788.27±491.02ml/d), P<0.05. The dialysis ultrafiltration volume in f-PD group (481.67±723.69ml/d, 632.77±687.89ml/d, 338.87±963.14ml/d, 750.43±849.69ml/d) were higher than those in i-PD group(343.30±520.00ml/d, 495.70±916.76ml/d, 341.78±925.57ml/d, 439.65±1297.13ml/d) during the whole follow-up period, but the differences were not statistically significant (P>0.05). (6).The exit-site infection, peritonitis, mechanical complications and technical survival were similar between the two groups (P>0.05). Conclusion Incremental peritoneal dialysis will not cause rapid decline of residual renal function in USPD patients, and the dialysis effect and complications are similar to full-dose peritoneal dialysis. Therefore, we recommend that USPD patients can be treated by incremental peritoneal dialysis.

Abstract Background and Aims Urgent-start peritoneal dialysis (USPD) has gained increasing worldwide attention. Studies have suggested that USPD has many advantages concerning the early complications, survival rates and medical expenses. Due to the lack of pre-dialysis education, most patients newly diagnosed with ESRD in China have less knowledge about the dialysis methods, whether HD or PD. So, some patients choose to receive the short-term hemodialysis with central venous catheter (HD-CVC) before USPD. Whether the HD-CVC affected USPD, and whether it was necessary for ESRD patients without indications of emergency dialysis to undergo HD-CVC transition before USPD, were addressed. So we investigate the effects of the HD-CVC on urgent-start peritoneal dialysis. Method Retrospective analysis was performed on patients who received USPD from August 2008 to March 2017 in the first affiliated hospital of Xi'an Jiaotong University. According to whether hemodialysis and central venous catheterization were performed before PD, these patients were divided into two groups: USPD group (HD-CVC was not performed before PD) and HD-PD group (HD-CVC was given after admission, and then the PD catheterization was performed within 2 weeks ). The follow-up time was 1 year. The differences in clinical biochemical indexes, dialysis dose, urine volume, residual renal function, dialysis adequacy, peritoneal dialysis complications and technical survival rate between the two groups were observed. Results 1.A total of 482 patients were enrolled in this study, including 315 in the USPD group (average age 48.56±14.92 years) and 167 in the HD-PD group (average age 48.87±14.49 years). The demographics and clinical biochemical indexes (including creatinine, glomerular filtration rate, and blood potassium before admission) were similar between the two groups, and the differences were not statistically significant(P>0.05).2. After PD for 1month, residual renal function, UKt/V and TKt/V in the USPD group were significantly higher than those in the HD-PD group, blood urea nitrogen and creatinine were significantly lower than those in the HD-PD group (USPD group: 4.41±4.0ml/min, 0.79±0.44, 2.17±1.39, 17.79±4.96mmol/L, 663.15±182.03umol/L; HD-PD group: 3.67±2.39ml/min, 0.64±0.42, 1.92±0.55, 19.08±8.21 mmol/L, 711.02±280.3umol/L), and the differences were statistically significant (P<0.05, respectively).After PD for 6months, the urine volume in the USPD group were significantly higher than those in the HD-PD group(USPD group:964.84±539.95ml/d; HD-PD group 794.39±569.17ml/d), and the difference was statistically significant (P=0.002). 3. During the whole follow-up period, the exit-site infection rate, peritonitis infection rate, mechanical complications and technical survival rate were similar between the two groups, with no statistically significant difference (P>0.05,respectively). Conclusion Hemodialysis with central venous catheter before USPD affected the residual renal function and dialysis adequacy. HD-CVC as a pretreatment is not recommended to the end-stage renal disease patients who required PD but without the indication of emergency dialysis.

ObjectivePreservation of residual renal function (RRF) is associated with improved survival. The aim of the present study was to identify independent predictors of RRF and urine volume (UV) in incident peritoneal dialysis (PD) patients.MethodsThe study included incident PD patients who were balANZ trial participants. The primary and secondary outcomes were RRF and UV, respectively. Both outcomes were analyzed using mixed effects linear regression with demographic data in the first model and PD-related parameters included in a second model.ResultsThe study included 161 patients (mean age 57.9 ± 14.1 years, 44% female, 33% diabetic, mean follow-up 19.5 ± 6.6 months). Residual renal function declined from 7.5 ± 2.9 mL/min/1.73 m2at baseline to 3.3 ± 2.8 mL/min/1.73 m2at 24 months. Better preservation of RRF was independently predicted by male gender, higher baseline RRF, higher time-varying systolic blood pressure (SBP), biocompatible (neutral pH, low glucose degradation product) PD solution, lower peritoneal ultrafiltration (UF) and lower dialysate glucose exposure. In particular, biocompatible solution resulted in 27% better RRF preservation. Each 1 L/day increase in UF was associated with 8% worse RRF preservation ( p = 0.007) and each 10 g/day increase in dialysate glucose exposure was associated with 4% worse RRF preservation ( p < 0.001). Residual renal function was not independently predicted by body mass index, diabetes mellitus, renin angiotensin system inhibitors, peritoneal solute transport rate, or PD modality. Similar results were observed for UV.ConclusionsCommon modifiable risk factors which were consistently associated with preserved RRF and residual UV were use of biocompatible PD solutions and achievement of higher SBP, lower peritoneal UF, and lower dialysate glucose exposure over time.

Objective Previous studies show that peritoneal Kt/V is an independent predictor of survival in anuric patients receiving continuous ambulatory peritoneal dialysis (CAPD). We studied whether peritoneal Kt/V has the same effect in CAPD patients with residual renal function. Design Observational cohort study. Setting Single dialysis center in a university teaching hospital. Patients New and prevalent CAPD patients. Methods We examined the 5-year follow-up results of our prospective study previously reported ( Kidney Int 2000; 58:400–7). A total of 270 CAPD patients were followed for up to 6 years. Dialysis adequacy indices, residual renal function, and nutritional data were monitored. Outcome Measures Primary outcomes included mortality and technique failure. Peritoneal Kt/V rather than total Kt/V was used for multivariate survival analysis. Results Average duration of follow-up was 35.1 ± 22.0 months. Average peritoneal Kt/V throughout the study was 1.59 ± 0.37; median residual glomerular filtration rate (GFR) 0.82 mL/minute. Five-year actuarial patient survival was 41.5%, and technique survival was 23.1%. Multivariate analysis showed that sex, age, duration of dialysis, presence of diabetes, serum albumin, dialysate-to-plasma creatinine ratio at 24 hours, peritoneal Kt/V, residual GFR, and normalized protein nitrogen appearance were independent factors of both actuarial patient survival and technique survival. For every 0.1 unit higher peritoneal Kt/V, relative mortality risk was 0.94 (95% CI 0.89 – 0.99, p = 0.03). When prevalent and new CAPD cases were analyzed separately, peritoneal Kt/V predicted survival only for prevalent CAPD patients. Conclusion We conclude that, in prevalent CAPD patients with relatively low levels of peritoneal clearance and residual renal function, a higher peritoneal Kt/V is associated with better survival. Peritoneal clearance below 1.6 – 1.7 likely has a major detrimental effect on the clinical outcome of CAPD patients with little residual renal function.

Introduction:Most of patients with chronic renal failure are affected by normochromic, normocytic anemia caused by different etiological factors. Anemia causes a series of symptoms in chronic renal failure, which can hardly be recognized from the uremic signs. Anemia adds to morbidity and mortality rates in patients affected by advanced chronic renal failure. Blood count partially improves during the first months after starting the chronic renal replacement therapy, in correlation with the quality of depuration program, with extension of erythrocyte lifetime and with hemoconcentration due to reduction of plasma volume. Recent trials found that higher residual renal function (RRF) significantly reduced co-morbidity, the rate and duration of hospitalization and risk of treatment failure. Objective: The aim of the study was to follow blood count parameters in 32 patients on chronic continuous ambulatory peritoneal dialysis (CAPD) during the first six months of treatment, to evaluate the influence of demographic and clinical factors on blood count and RRF, and to examine the correlation between RRF and blood count parameters. Method: A total of 32 patients affected by end-stage renal disease of different major cause during the first six months of CADP treatment were studied. RRF and blood count were evaluated as well as their relationship during the follow-up. Results: Blood count significantly improved in our patients during the first six months of CAPD treatment even if Hb and HTC failed to reach normal values. Iron serum level slightly decreased because of more abundant erythropoiesis and iron utilization during the first six months of treatment. RRF slightly decreased. After six months of CAPD treatment, the patients with higher RRF had significantly higher Hb, HTC and erythrocyte number and a lot of positive correlations between RRF and anemia markers were observed. Conclusion: After 6-month follow-up period, the patients with higher RRF had significantly higher blood count parameters, and several positive correlations between RRF and blood count markers were confirmed.

Figure: Background and Aims in Italy only a minority of uremic patients perform peritoneal dialysis (PD). In dialysis centers where PD is practiced and proposed the prevalence is no more than 23%. Proposed advantages of PD over HD are a more preserved Residual renal function (RRF), that has been associated with better survival, and better Quality of life (Qol) due to possible more preservation of previous lifestyle, independence, possibility of traveling, and flexibility. Incremental peritoneal dialysis is a promising way to further improve Qol and to preserve RRF. Lastly, PD is less expensive than HD. Aim of this study has been to retrospectively evaluate our ten-years experience of PD treatment on survival, dialysis adequacy, preservation of RRF and nutrition in uremic patients followed at our Dialysis Center. Method We retrospectively evaluated all the incident patients that started PD treatment due to uremia from 01-01-2008 to 31-12-2018 at the U.O. Nephrology ASST Spedali Civili of Brescia. The exclusion criteria were time of dialysis treatment less than 3 months and absence of previous dialytic treatment or kidney transplantation. For each patient anthropometric, clinical-anamnestic data and comorbidities at dialysis start were recorded. Data on dialysis adequacy, nutrition, RRF and PD dialysis modality performed were also recorded. Results During the observation period 329 patients started PD. 60 were excluded due to follow-up of less than 3 months. Therefore, 269 patients (males 160, 59%) were studied. The average age was 65±16 years, BMI 24±4 kg/m2. Comorbidities were: hypertension (87%), diabetes mellitus (32%), cerebral vascular disease (26%) and ischemic heart disease (25%). The mean duration of dialysis treatment was 2.1±1.5 years. At the end of ten-years follow-up 24% of patients have had a kidney transplant, 18% were on PD treatment, 17% have had a shift towards HD, 39% had died. The main causes of death were: infection (39%) and cardiovascular disease (31%). The most common dialysis modality performed was APD (61%); CAPD was performed in 39% of pts. Dialysis modality (CAPD; APD), nutrition parameters (PNA; BMI), as well as RRF, expressed as an average value during follow-up, are shown in Figure 1. 81 patients (30%) were treated with incremental PD; 85% of them with manual exchanges. The comparison of dialysis parameters between incremental PD and standard PD are shown in Figure 2. Multivariate analysis with survival as dependent variable (Figure 3), showed that age, diabetes mellitus, and low wKt/V were independently associated with an increased risk of mortality. Diuresis volume and male gender were protective factors. No independent influence on mortality of the dialysis treatment modality was found. Conclusion In this ten-years experience of patients undergoing PD at our Center, incremental PD seems to be a protective factor for the maintenance of a preserved diuresis and better dialysis adequacy, and these factors are associated with better survival of the patients.

Background: This study analysed children with end-stage renal disease treated with automated peritoneal dialysis (APD) in our centre to explore the risk factors associated with residual renal function (RRF) loss. Methods: Children treated with APD as the initial renal replacement therapy regimen from January 2008 to December 2016 were included. All the children had a daily urine volume of ≥100 ml/m2 when APD was initiated and a dialysis follow-up time of ≥12 months. A daily urine volume of <100 ml/m2 after 12 months of APD treatment was defined as loss of RRF. Possible risk factors that may be associated with RRF loss were analysed. Results: A total of 66 children were included in the study. After 12 months of APD treatment, the daily urine volume decreased by 377.45 ± 348.80 ml/m2, the residual glomerular filtration rate decreased by 6.39 ± 3.69 ml/min/1.73 m2 and 29 of the patients (43.9%) developed RRF loss. The higher risk of RRF loss after 1 year of APD treatment was most pronounced in patients with daily urine volume of ≤400 ml/m2 before treatment, higher glucose exposure and higher ultrafiltration volume, while the lower risk of RRF loss was in patients with administration of diuretics. Each increase of 1 g/m2/day glucose exposure was associated with a 5% increase in RRF loss (odds ratio (OR) 1.05, p = 0.023) and each increase of 1 ml/m2/day ultrafiltration volume was associated with a 1% increase in RRF loss (OR 1.01, p = 0.013). Conclusion: In children undergoing APD, the risk for loss of RRF is associated with low urine volume at the start of APD, high glucose loading and high peritoneal ultrafiltration volume, while preservation of RRF is associated with the usage of diuretics.

Objective To evaluate the adequacy of dialysis in patients on nighttime intermittent peritoneal dialysis (NIPD). Design Retrospective review of prospectively collected data. Patients Seven patients on NIPD. Measurements The fast peritoneal equilibration test (PET) was used to determine peritoneal membrane permeability for small solutes. Adequacy of dialysis measured by 24hour collections of dialysate and urine for weekly KT/V and creatinine clearance in liters/week/1.73 m2 was assessed in patients with (n=3) and without (n=4) residual renal function and evaluated in concert with the patient's clinical status. Outcome for each patient was also noted. Results Five of the patients had a high-average dialysate/serum creatinine by PET (>0.66). Despite a weekly KT/V of 1.7 or more, four of the seven patients on NIPD were uremic and either transferred to hemodialysis or continuous cycling peritoneal dialysis (CCPD). A fifth patient had a KT/V of 1.4 and was also uremic on NIPD. The patient who was clinically well and continued on NIPD had significant residual renal function. Conclusions NIPD should be restricted to patients with high-average dialysate/serum creatinine as determined by PET and residual renal function or those with high dialysate/serum creatinine. Extended dialysis time and large volumes of dialysate are required for successful NIPD in patients without residual renal function. Accepted parameters of dialysis adequacy used for patients on continuous peritoneal dialysis are not appropriate for intermittent forms of peritoneal dialysis.

ABSTRACT. Several studies have recently confirmed that hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) survival is highly associated with delivered therapy Kt/Vurea. A direct comparison of equivalently dosed CAPD and HD has not previously been performed. A total of 968 incident HD patients at the Regional Kidney Disease Program from 1987 to June 1995 were studied, and these results were compared with those of the Canadian-United States prospective trial (CANUSA) consisting of 680 incident CAPD patients from September 1990 to December 31, 1992, with follow-up through December 31, 1993. All patients had quantitation of urea nitrogen for a total delivered dialysis session. On HD, in vivo, 2-pool, pre- and post-blood urea nitrogen kinetic modeling was performed with residual renal function determined every 6 mo. Patients were characterized by age, gender, race, renal diagnosis, and comorbid conditions. A Cox proportional hazards model was used to evaluate the effect of the individual comorbid conditions and the effect of dialysis therapy in the time-dependent method. The mean total Kt/V, both residual renal function and dialytic therapy in the HD patients, was 1.59. The CANUSA-delivered weekly Kt/V was 2.38 at the beginning of the baseline period and 1.99 after 24 mo of follow-up. When the peak concentration hypothesis was used, a Kt/V of 1.59 on HD was equivalent to a weekly CAPD dose of 2.1 to 2.2. A 1-unit increase in Kt/V was associated with 7% lower risk of death on HD and with a similar 8% lower risk of death while on CAPD. Patients with diabetes aged 46 to 60 yr had virtually identical 2-yr survival estimates on HD (83 to 90%), compared with CAPD (83 to 89%), with Kt/V ranges from 0.84 to 1.70 in HD and from 1.6 to 2.2 weekly Kt/V on peritoneal dialysis. Comparisons between HD and CAPD in older patients with diabetes yielded comparable results. Patient survival is highly influenced by delivered dialysis in both HD and peritoneal dialysis. Carefully matching of the therapies with delivered Kt/V demonstrates little differences in the survival outcome of HD and peritoneal dialysis patients, in contrast to some previous reports.

Abstract Background: Patients with chronic kidney disease (CKD) had a high risk of fatal arrhythmias. The extended corrected QT (QTc) interval is a hallmark of ventricular arrhythmias and sudden cardiac death. Studies have shown that QT interval and QTc were prolonged with the declination in renal function. Notably, QTc prolongation is significantly increased in patients undergoing hemodialysis. However, there were no results available in patients with peritoneal dialysis (PD). This study aimed to report the changes in QT interval and QTc in PD patients.Methods: A total of 66 PD patients were enrolled. The duration of follow-up was 1 year. The demographics, and the etiology of patients were recorded. QTc of ECG and clinical biochemical indexes before dialysis and at 6 months after PD and 1year after PD were determined and analyzed. Dialysis adequacy and peritoneal transport function were assessed in each patient.Results: (1) A total of 66 PD incident patients, including 50 males and 16 females, with an average age of 43.56±15.15 years (males: 43.74±15.53 years; females: 43.00 ± 15.92 years) were enrolled. In terms of etiology, 37 patients (56.06%) had chronic nephritis, followed by diabetic nephropathy in 11 patients (16.67%), IgA nephropathy with 8 patients (12.12%). The peritoneal transport test showed that the most of the peritoneal transport function was low average transport( 25, 37.88%), the least was high transport(2, 3.03%).(2) During the follow-up period, all patients reached the standard of PD. Compared with baseline before dialysis, anemia, low albumin, blood pressure, blood urea nitrogen, creatinine, uric acid, potassium, calcium, phosphorus and parathyroid hormone were improved after PD at 6 months and 1year. The residual renal function was gradually decreases during the follow-up. There were no significant differences in clinical indexes between 6 months and 1 year after PD.(3) The mean QTc of all patients were stable during 1-year follow-up period (pre-PD: 413.49±29.95ms; 6 months: 423.05±51.96ms; 1 year: 409.29±32.32ms, P>0.05). According to gender, the QTc in male patients and in female patients had the same results (P>0.05, respectively).(4) Before PD, diastolic blood pressure (r=-0.261,P=0.039), calcium concentration (r=-0.360,P=0.004) and hemoglobin level (r=-0.432,P=0.000) were found to be the risk factors of QTc prolongation. They were negatively correlated with QTc in end-stage renal disease patients. After patients starting PD, the observed clinical indicators showed no relevance to QTc anymore.Conclusion: Different from hemodialysis induced QTc prolongation, PD did not increase the patient's QT interval and QTc interval. This phenomenon was reported for the first time, suggesting that myocardial electrical activity might be more stable in PD patients.

Abstract Background Renin-angiotensin system inhibitors (RASIs), either angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, are widely used in patients with non-dialysis chronic kidney disease, as a renin-angiotensin system (RAS) blockade has renoprotective effects. Several studies show that preserving residual renal function is important for a better prognosis in peritoneal dialysis (PD) patients. Here, we systematically reviewed the beneficial or harmful effects of RAS blockade in PD patients. Methods PubMed, the Cochrane Library, Embase, the Ichushi web databases, and other resources were selected to search clinical guidelines, systematic reviews, and randomized controlled trials (RCT) published before April 14, 2017, using “peritoneal dialysis,” “angiotensin-converting enzyme inhibitors,” “angiotensin II type 1 receptor blockers,” and “randomized controlled trial” as keywords. Desired results were total mortality, technical survival, urine volume, residual renal function calculated by glomerular filtration rate (GFR), cardiovascular events, and anuria progression rate. The study protocol is registered in PROSPERO (International Prospective Register of Systematic Reviews) under the registration number CRD42018104106. Results Of a total of 339 studies, eight were identified as suitable for the analysis. Only one study was blinded, whereas the other seven studies were open-label. RASI appeared to preserve residual renal function, GFR (4 studies, 163 participants, mean difference [MD] 0.97 mL/min/1.73 m2, 95% confidence interval [CI] 0.49–1.44), and urine volume (6 studies, 194 participants, MD 142.56 mL 95% CI 25.42–259.69), although there were no beneficial effects of RASI on total mortality, technical survival, cardiovascular events, and anuria rate. Conclusions Our analysis found that RASIs contribute to preserving GFR and urine volume in PD patients. As the number of study participants is small, further studies with a larger sample size are required.
