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.

Abstract : Introduction: Peritoneal dialysis (PD) is as effective as hemodialysis and often provides a better quality of life for patients. Despite this, the replacement therapy remains little established in our country with a prevalence of less than 1% of patients with end-stage renal disease. The objective of this work is to report the development and complications of PD in our center. Patients and methods: This is a retrospective study including all patients on PD between October 2008 and March 2019. We noted their demographic and clinical data at their initiation in peritoneal dialysis and we followed their evolution to discuss infectious and mechanical complications as well as the causes of PD exit. Results: During the study period, 456 patients were admitted for end-stage renal disease. Among these patients, only 28 (6.1%) were put on PD including two diabetics. Their average age was 37.7 years with a sex ratio of 0.8. The average body surface area was 1.59 m² with an average residual renal function of 6.05 ml / min. PD was chosen as the first intention in 20 patients while 8 patients were on hemodialysis. The evolution was marked by a median survival of the technique of 18.5 months characterized by 8 episodes of peritonitis in 4 patients corresponding to a rate of 1 episode over 56 months. Regarding mechanical complications, we noted 9 omentum aspirations, 1 leak in one case and 1 umbilical hernia requiring surgical recovery in a patient. Out of 28 patients, 17 discharges were identified; 10 patients (67%) were transferred to hemodialysis, 4 died and only 3 patients (18%) were transplanted. The final transfer to hemodialysis was related to mechanical complications in 5 cases, loss of ultrafiltration in one case, repeated hydro-sodium overload in one case, peritonitis in one case and social reasons in two cases. Conclusion: PD is an effective technique which preserves residual renal function and quality of life but its prevalence remains low in the order of 6% of patients treated for end-stage renal disease. The complications are dominated in our context by the mechanical complications main cause of final transfer in hemodialysis.

Abstract. Residual renal function (RRF) in end-stage renal disease is clinically important as it contributes to adequacy of dialysis, quality of life, and mortality. This study was conducted to determine the predictors of RRF loss in a national random sample of patients initiating hemodialysis and peritoneal dialysis. The study controlled for baseline variables and included major predictors. The end point was loss of RRF, defined as a urine volume <200 ml/24 h at approximately 1 yr of follow-up. The adjusted odds ratios (AOR) and P values associated with each of the demographic, clinical, laboratory, and treatment parameters were estimated using an “adjusted” univariate analysis. Significant variables (P < 0.05) were included in a multivariate logistic regression model. Predictors of RRF loss were female gender (AOR = 1.45; P < 0.001), non-white race (AOR = 1.57; P = <0.001), prior history of diabetes (AOR = 1.82; P = 0.006), prior history of congestive heart failure (AOR = 1.32; P = 0.03), and time to follow-up (AOR = 1.06 per month; P = 0.03). Patients treated with peritoneal dialysis had a 65% lower risk of RRF loss than those on hemodialysis (AOR = 0.35; P < 0.001). Higher serum calcium (AOR = 0.81 per mg/dl; P = 0.05), use of an angiotensin-converting enzyme inhibitor (AOR = 0.68; P < 0.001), and use of a calcium channel blocker (AOR = 0.77; P = 0.01) were independently associated with decreased risk of RRF loss. The observations of demographic groups at risk and potentially modifiable factors and therapies have generated testable hypotheses regarding therapies that may preserve RRF among end-stage renal disease patients.

Background This report describes the status of renal replacement therapy (RRT), particularly continuous ambulatory peritoneal dialysis (CAPD), in Romania (a country with previously limited facilities), outlines the fast development rate of CAPD, and presents national changes in a European context. Methods Trends in the development of RRT were analyzed in 2003 on a national basis using annual center questionnaires from 1995 to 2003. Survival data and prognostic risk factors were calculated retrospectively from a representative sample of 2284 patients starting RRT between 1 January 1995 and 31 December 2001 (44% of the total RRT population investigated). Results The annual rate of increase in the number of RRT patients (11%) was supported mainly by an exponential development of the CAPD population (+600%); the hemodialysis (HD) growth rate was stable (+33%) and renal transplantation had a marginal contribution. The characteristics of both HD and PD incident patients changed according to current European epidemiology (increasing age and prevalence of diabetes and nephroangiosclerosis). There were significant differences between PD and HD incident populations, PD patients being significantly older and having a higher prevalence of diabetic nephropathy and baseline comorbidities, probably reflecting different inclusion policies. The estimated overall survival of RRT patients in Romania was 90.6% at 1 year [confidence interval (CI) 89.4 – 91.8] and 62.2% at 5 years (CI 59.4 – 65.0). The initial treatment modality did not significantly influence patients’ survival. There was no difference in unadjusted technique survival during the first 2 years; afterwards, there was a clear advantage for HD, with more patients being transferred from PD to HD. Several factors seemed to significantly and negatively influence PD patients’ survival (Cox regression analysis): male gender, lack of predialysis erythropoietin treatment, and initial comorbidities. Stratified analysis to discover the influence of these factors on patients’ survival revealed that HD was associated with an increased risk of death in the younger nondiabetic end-stage renal disease population, regardless of other coexisting comorbid conditions. However, in older patients (>65 years) and in diabetics, regardless of the presence or absence of associated comorbid conditions, there was no significant difference in death rates between HD and PD patients. Conclusions We report an impressive quantitative and qualitative development of CAPD in one of the rapidly growing Central and Eastern Europe countries. CAPD should be the method of choice for young nondiabetic end-stage renal disease patients. Improvement in predialysis nephrologic care and in transplantation rates is required to further ensure the ultimate success of the Romanian PD program.

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.

Cardiovascular disease accounts for more than half of all deaths in end-stage renal disease patients receiving chronic peritoneal dialysis (PD) treatment. The recent demonstration of the important association between residual renal clearance (but not PD clearance) and overall and cardiovascular survival in chronic PD patients has led us to further explore the mechanisms that can potentially explain the close link between residual renal function and cardiovascular disease in this population. This John Maher Award Lecture provides a review of my own work and that of other groups that provides support for the importance of residual renal function not only in providing small-solute clearance but also in maintaining the cardiovascular health, nutrition status, and wellbeing of PD patients. Data are provided to demonstrate why preservation of residual renal function may be the key to improving survival and cardiovascular outcomes in PD patients.
