Abstract
CONCLUSION There were significant differences between Vwat and Vbis and between Kt/Vwat and Kt/Vbis. Kt/Vwat may underestimate small-solute dialysis adequacy in most cases. Kt/Vbis instead of Kt/Vwat could be accounted for in creating individualized dialysis prescriptions if the patient has no obvious clinical symptoms.

Abstract
Peritoneal dialysis (PD) is a widely used sustainable kidney replacement therapy. Prolonged use of PD fluids is associated with mesothelial-mesenchymal transition, peritoneal fibrosis, and eventual ultrafiltration (UF) failure. However, the impact of pressure on the peritoneum remains unclear. In the present study, we hypothesized increased pressure is a potential contributing factor to peritoneal fibrosis and investigated the possible mechanisms. In vitro experiments found that pressurization led to a mesenchymal phenotype, the expression of fibrotic markers and inflammatory factors in human mesothelial MeT-5A cells. Pressure also increased cell proliferation and augmented cell migration potential in MeT-5A cells. The mouse PD model and human peritoneum equilibrium test (PET) data both showed a positive association between higher pressure and increased small solute transport, along with decreased net UF. Mechanistically, we found that significant upregulation of CD44 in mesothelial cells upon pressurization. Notably, the treatment of CD44 neutralizing antibodies prevented pressure-induced phenotypic changes in mesothelial cells, while a CD44 inhibitor oligo-fucoidan ameliorated pressure-induced peritoneal thickening, fibrosis, and inflammation in PD mice. To conclude, intraperitoneal pressure results in peritoneal fibrosis in PD via CD44-mediated mesothelial changes and inflammation. CD44 blockage can be utilized as a novel preventive approach for PD-related peritoneal fibrosis and UF failure.

Abstract
Rationale & Objective Given the high burden of dementia in dialysis patients, the dialysis workforce needs to be prepared to provide high-quality, person-centered dementia care. We explored comfort with and knowledge of dementia among US dialysis care providers. Study Design Web-based survey. Setting & Participants Emails were sent to National Kidney Foundation and National Association of Nephrology Technicians/Technologists membership listservs (September 26, 2022-October 22, 2022). In total, 1,121 respondents had complete data for analysis (57%, 35-49 years; 62% female; 62%/22% White/African American) including 81 physicians, 61 advanced practice providers, 230 nurse managers, 260 nurses, 202 social workers, 195 dietitians, and 86 dialysis patient care technicians. Exposures Provider role, age, tenure, self-reported gender, previous dementia training, and awareness of dementia guidance. Outcomes Dementia Knowledge (assessed using Dementia Knowledge Assessment Scale [DKAS; score range, 0-25]). Analytic Approach Characteristics of respondents, comfort with dementia care, and dementia knowledge were summarized and tabulated overall and by role. Robust regression was used to obtain coefficients confidence intervals for the associations between characteristics and DKAS scores, adjusting for role and tenure. Free-text responses to an open-ended question about treating patients with dementia or cognitive impairment were analyzed using thematic analysis. Results Dementia knowledge among US dialysis providers may be limited (overall DKAS score = 17; range, 13-21 across roles), despite most reporting knowing when patients had dementia (97%) and receiving training in dementia care (62%). Further, training may be inadequate: those who reported receiving dementia training had lower DKAS scores than those who reported not receiving training (β, -3.9; 95% CI, -4.4 to -3.4). Thematic analysis of open-ended responses suggested that the impact of dementia on dialysis care and management and treatment beyond dialysis care are challenging for providers. Limitations Data were self-reported and limited information was gathered about quality, content, and timing of dementia training received. Conclusion Many US dialysis care providers had suboptimal dementia knowledge, despite reporting being comfortable with providing dementia care and reporting they received prior training. Qualitative findings indicate complexity among providers regarding comfort with and knowledge of treating patients with cognitive impairment. Targeted training for the dialysis workforce in dementia knowledge and best practices for person-centered dementia care is warranted.

Abstract
Rationale & Objective The development of anuria has been linked to worse clinical outcomes in patients undergoing peritoneal dialysis (PD). Our objective was to investigate the incidence, risk factors, and associated clinical outcomes of anuria within the first year after starting PD. Study Design Retrospective cohort study. Setting & Participants Patients who started continuous ambulatory peritoneal dialysis at our center between 2006 and 2020 were included and followed up until January 31, 2023. Exposure Age, sex, diabetes, temporary hemodialysis, angiotensin-converting enzyme inhibitors (ACEis) or angiotensin II receptor blockers (ARBs), diuretics, baseline urine volume, serum albumin, daily glucose exposure, peritonitis, and incremental PD. Outcomes The primary outcome was early anuria, defined as 24-hour urine volume ≤100 mL within the first year of PD initiation. Secondary outcomes included all-cause mortality, cardiovascular disease mortality, technique failure, and peritonitis. Analytical Approach Cox proportional hazards model. Results A total of 2,592 patients undergoing continuous ambulatory peritoneal dialysis aged 46.7 ± 14.9 years were recruited. Among them, 58.9% were male, and 24.0% had diabetes. Within the first year of PD therapy, 159 (6.13%) patients developed anuria, with a median duration of 7.53 (interquartile range, 3.93-10.0) months. Higher baseline urine volume (hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.90-0.97), higher serum albumin (HR, 0.92; 95% CI, 0.88-0.95), having diabetes before PD (HR, 0.57; 95% CI, 0.35-0.92), and prescribed incremental PD (HR, 0.27; 95% CI, 0.14-0.51) were associated with a reduced risk for early anuria, whereas a higher level of daily glucose exposure (HR, 1.01; 95% CI, 1.00-1.01) was identified as a risk factor for early anuria. Subgroup analyses showed that using ACEis or ARBs was linked to a lower risk of early anuria (HR, 0.25; 95% CI, 0.09-0.69) in diabetic patients. Treating early anuria as a time-dependent covariate, early anuria was associated with a higher risk for all-cause mortality (HR, 1.69; 95% CI, 1.23-2.32) and technique failure (HR, 1.43; 95% CI, 1.00-2.04) after adjusting for confounding factors. Limitations Single-center and observational study. Conclusions Among PD patients at a single center in China, early anuria was relatively uncommon but associated with an increased risk of mortality and PD technique failure. Incremental PD, higher baseline urine output and serum albumin, and lower daily glucose exposure were associated with a lower risk of early anuria. Clinical trials are needed to evaluate the optimal PD techniques to preserve residual kidney function and maximaze outcomes.

Abstract
PURPOSE OF REVIEW The efficiency of peritoneal dialysis (PD) as a life-sustaining replacement therapy for patients with kidney failure relies on the integrity and function of the peritoneal membrane. Here, we review the most recent advances in the understanding of the peritoneal membrane and its role in PD. RECENT FINDINGS A recent update of the ISPD guidelines proposed a revised definition of membrane dysfunction, emphasizing the importance of fluid balance in patients treated with PD and identified three main mechanisms leading to insufficient peritoneal ultrafiltration (UF). The Bio-PD study, the first genomewide association study in PD, demonstrated that 20% of the interindividual variability in the peritoneal solute transfer rate is genetically determined, and identified several loci of potential relevance for peritoneal transport. A candidate-gene approach identified and characterized a common and functional variant in the promoter of the AQP1 gene associated with water transport and clinical outcomes in PD. Innovative strategies to preserve the integrity of the peritoneal membrane and to enhance UF are also discussed, including the use of gliflozins; steady glucose concentration PD; modulation of GLUT proteins; and cytoprotective additives. SUMMARY A comprehensive understanding of the peritoneal membrane and of the mechanisms driving UF may help individualizing PD prescription and improving outcomes in patients treated with PD.

Abstract
BACKGROUND Peritoneal dialysis (PD) is a home-based kidney replacement therapy (KRT) performed in people with kidney failure. PD can be performed by manual filling and draining of the abdominal cavity, i.e. continuous ambulatory PD (CAPD), or using a device connected to the PD catheter that is programmed to perform PD exchanges, i.e. automated PD (APD). APD is considered to have several advantages over CAPD, such as a lower incidence of peritonitis, fewer mechanical complications, and greater psychosocial acceptability. Acknowledging the increasing uptake of APD in incident and prevalent patients undergoing PD, it is important to re-evaluate the evidence on the comparative clinical and patient-reported outcomes of APD compared to CAPD. This is an update of a Cochrane review published in 2007. OBJECTIVES To compare clinical and patient-reported outcomes of APD to CAPD in people with kidney failure. SEARCH METHODS In this update, we searched the Cochrane Kidney and Transplant Register of Studies until 29 August 2024. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal, and ClinicalTrials.gov. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing APD with CAPD in adults (≥ 18 years) with kidney failure. DATA COLLECTION AND ANALYSIS Two authors independently screened the search results and extracted data. Data synthesis was performed using random-effects meta-analyses, expressing effect estimates as risk ratios (RR) with 95% confidence intervals (CI) for dichotomous data and mean differences (MD) with 95% CIs for continuous data. Certainty in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. MAIN RESULTS Two RCTs (131 randomised people) comparing APD with CAPD were included in this update. One RCT had a follow-up of six months, and one RCT had a follow-up of 24 months. The risk of bias in the included studies was mostly low, except for the high risk of performance bias for subjective outcomes. The evidence is very uncertain about the effect of APD compared to CAPD on death, hospitalisations, PD-related peritonitis, change of dialysis modality, residual kidney function, health-related quality of life (HRQoL), overhydration, blood pressure, exit-site infections, tunnel infections, mechanical complications, PD catheter removal, or dialysis adequacy measures. These results were largely based on low to very low certainty evidence; hence, caution is warranted when drawing conclusions. AUTHORS' CONCLUSIONS Insufficient evidence exists to decide between APD and CAPD in kidney failure patients with regard to clinical and patient-reported outcomes. Therefore, current evidence is insufficient as a guide for clinical practice. Given that the sample sizes of existing studies are generally small with insufficient follow-up, there is a need for large-scale, multicentre studies. Future research should focus on possible differences between APD and CAPD in residual kidney function, euvolaemia, and patient-reported outcomes such as HRQoL, symptoms, patient satisfaction and life participation.

Abstract
BACKGROUND Worldwide, the uptake of peritoneal dialysis (PD) compared with hemodialysis remains limited. This study assessed organizational structures, availability, accessibility, affordability and quality of PD worldwide. METHODS This cross-sectional study relied on data from kidney registries as well as survey data from stakeholders (clinicians, policymakers and advocates for people living with kidney disease) from countries affiliated with the International Society of Nephrology (ISN) from July to September 2022. RESULTS Overall, 167 countries participated in the survey. PD was available in 79% of countries with a median global prevalence of 21.0 [interquartile range (IQR) 1.5-62.4] per million population (pmp). High-income countries (HICs) had an 80-fold higher prevalence of PD than low-income countries (LICs) (56.2 pmp vs 0.7 pmp). In 53% of countries, adults had greater PD access than children. Only 29% of countries used public funding (and free) reimbursement for PD with Oceania and South East Asia (6%), Africa (10%) and South Asia (14%) having the lowest proportions of countries in this category. Overall, the annual median cost of PD was US$18 959.2 (IQR US$10 891.4-US$31 013.8) with full private out-of-pocket payment in 4% of countries and the highest median cost in LICs (US$30 064.4) compared with other country income levels (e.g. HICs US$27 206.0). CONCLUSIONS Ongoing large gaps and variability in the availability, access and affordability of PD across countries and world regions were observed. Of note, there is significant inequity in access to PD by children and for people in LICs.

Abstract
BACKGROUND Urinary Dickkopf 3 (DKK3) excretion is a recently established biomarker of renal functional development. Its excretion into the peritoneal cavity has not been reported. We here studied DKK3 in peritoneal dialysis. METHODS DKK3 was assessed in serum, urine and dialysate in a prevalent adult peritoneal dialysis cohort and its concentration analyzed in relation to creatinine and clinical characteristics. RESULTS Highest DKK3 concentrations were found in serum, followed by urine. Dialysate concentrations were significantly lower. Dialysate DKK3 correlated with both other compartments. Serum, dialysate and urine values were stable during three months of follow-up. Continuous ambulatory dialysis (CAPD) but not cycler-assisted peritoneal dialysis (CCPD) volume-dependently increased peritoneal DKK3 in relation to creatinine. RAAS blockade significantly decreased urinary, but not serum or peritoneal DKK3. CONCLUSION Our data provide a detailed characterization of DKK3 in peritoneal dialysis. They support the notion that the RAAS system is essential for renal DKK3 handling.

[PMID: 38671537 PMCID: PMC11377804 DOI: 10.1681/asn.0000000000000361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 04/22/2024] [Indexed: 04/28/2024] Open
Abstract
Key Points
Automated peritoneal dialysis (APD) had a higher carbon impact than continuous ambulatory peritoneal dialysis (CAPD).This was due to higher emissions from the manufacture and disposal of APD consumables, and their higher weight, meaning greater transport emissions.Polyvinyl chloride recycling can partially mitigate peritoneal dialysis–associated emissions.
Background
As climate change escalates with increasing health impacts, health care must address its carbon footprint. The first critical step is understanding the sources and extent of emissions from commonly utilized clinical care pathways.
Methods
We used attributional process-based life-cycle analysis to quantify CO2 equivalent emissions associated with the delivery of Baxter’s HomeChoice automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) in Australia.
Results
The annual per-patient carbon emissions attributable to the manufacture and disposal of peritoneal dialysis (PD) fluids and consumables were 1992 kg CO2 equivalent emissions for APD and 1245 kg CO2 equivalent emissions for CAPD. Transport impacts varied depending on the distance between the site of manufacture of PD fluids and consumables and the state of origin of the patient. Therefore, the total impact of providing PD also differed by Australian state, ranging from 2350 to 4503 kg CO2 equivalent emissions for APD and from 1455 to 2716 kg CO2 equivalent emissions for CAPD. Recycling of polyvinyl chloride (PVC) could reduce emissions by up to 14% for APD and 30% for CAPD depending on the distance between the site of PVC waste generation and the recycling center.
Conclusions
This study demonstrated higher per-patient carbon emissions from APD compared with CAPD, owing to both higher fluid and consumable requirements and the consequent higher transport impacts. PVC recycling can partially mitigate PD-associated carbon emissions.

Abstract
The management of end-stage kidney disease (ESKD) has been constantly evolving over the last decade with the development of targeted approaches. In this field, telemedicine and remote monitoring are based on the availability of new cyclers that allow for bidirectional communication (between patient and physician) and for the application of the Sharesource cloud-based platform. These technologies allow patients with ESKD to undergo automated peritoneal dialysis (APD) at home. However, these approaches are not well standardized and largely applied yet. Therefore, this study aimed to elaborate a protocol for the utilization of the Sharesource platform to facilitate the practical management of patients treated with APD. A series of expert meetings were held between September 2022 and January 2023 in Italy. The participants (ten nephrologists and five nurses) from nine Italian public dialysis centers shared their opinions, examined the current scientific literature in the field, and reviewed the key characteristics of the Sharesource system to achieve a common position on this topic. A detailed and practical document containing experts' opinions and suggestions on the use of the Sharesource platform for the management of patients treated with APD was produced. This expert opinion might represent a new useful instrument in clinical practice for managing patients undergoing home-based peritoneal dialysis (PD) through the Sharesource platform, which is valid not only for Italy. These recommendations pave the way to novel patient-centered and personalized therapeutic approaches for ESKD and highlight the advantages of telemedicine and remote monitoring in the management of patients with ESKD undergoing PD and its positive impact on their quality of life.

Cardiovascular and All-Cause Mortality Is Affected by Serum Magnesium and Diet Pattern in a Cohort of Dialysis Patients. J Clin Med 2024; 13:4024.

Abstract
Background: Hypomagnesaemia is associated with an increased overall mortality in patients with chronic kidney disease on dialysis (CKD-5D). Mediterranean-style diet (MD), having a high magnesium content, can serve as a form of dietary magnesium supplementation. We examined whether there is a potential link between increased Mediterranean Diet score (MDS) and elevated serum magnesium (sMg) to assess its impact on reducing mortality risk in CKD-5D patients. Methods: In this multi-center prospective observational study, 117 CKD-5D patients (66 on hemodialysis and 51 on peritoneal dialysis) with a mean age of 62 ± 15 years were studied for a median follow-up period of 68 months. After baseline assessment, including measurement of sMg and MDS, all patients were followed up for cardiovascular (CV) and all-cause mortality. Results: Forty deaths occurred, 58% of which were cardiovascular. Patients who were above the median value of sMg (2.2 mg/dL) had a 66% reduction in CV (crude HR, 0.34; 95% CI, 0.11-0.70), and 49% reduction in all-cause (crude HR, 0.51; 95% CI, 0.27-0.96) mortality, even after adjustment for age, malnutrition inflammation score, left ventricular mass index, peripheral vascular disease and diabetes. Similar results were obtained when sMg was analyzed as a continuous variable. sMg was associated directly with MDS (r = 0.230; p = 0.012). Conclusions: Higher sMg levels are strongly and independently associated with reduced CV and all-cause mortality in CKD-5D patients. A strong correlation exists between MDS and sMg. Elevated sMg levels, achieved through MD adherence, can significantly reduce CV mortality, implicating MD as a mediator of the association between sMg and CV mortality.

Abstract
Background Due to the slower dissipation of the osmotic gradient, icodextrin-based solutions, compared to glucose-based solutions, can improve water removal. We investigated scenarios where one icodextrin-based long dwell (Extraneal) replaced two glucose-based exchanges. Methods The three-pore model with icodextrin hydrolysis was used for numerical simulations of a single exchange to investigate the impact of different peritoneal dialysis schedules on fluid and solute removal in patients with different peritoneal solute transfer rates (PSTRs). We evaluated water removal (ultrafiltration, UF), absorbed mass of glucose (AbsGluc) and carbohydrates (AbsCHO, for glucose and glucose polymers), ultrafiltration efficiency (UFE = UF/AbsCHO) per exchange, and specified dwell time, and removed solute mass for sodium (ReNa), urea (ReU), and creatinine (ReCr) for a single peritoneal exchange with 7.5% icodextrin (Extraneal®) and glucose-based solutions (1.36% and 2.27%) and various dwell durations in patients with fast and average PSTRs. Results Introducing 7.5% icodextrin for the long dwell to replace one of three or four glucose-based exchanges per day leads to increased fluid and solute removal and higher UF efficiency for studied transport groups. Replacing two glucose-based exchanges with one icodextrin exchange provides higher or similar water removal and higher daily sodium removal but slightly lower daily removal of urea and creatinine, irrespective of the transport type present in the case of reference prescription with three and four daily exchanges. Conclusion One 7.5% icodextrin can replace two glucose solutions. Unlike glucose-based solutions, it resulted only in minor differences between PSTR groups in terms of water and solute removal with UFE remaining stable up to 16 h.

Abstract
This review outlines the epidemiology, characteristics, risk factors, and prognosis of peritoneal dialysis (PD)-related peritonitis, PD catheter-related infections, and the effects of assisted PD in elderly patients from the Japanese perspective. Based on the literature, the incidence of peritonitis is likely to be higher in elderly patients than in younger patients. The most frequent causative bacteria in elderly patients are Gram-positive bacteria, as in adult PD patients, most commonly due to transcatheter infection. However, elderly patients may have difficulty recognizing cloudy drainage fluid due to decreased visual acuity. Hypokalemia, the use of gastric acid suppressants, prophylactic antibiotic use before endoscopy, biocompatible fluids and hypoalbuminemia considered modifiable risk factors for peritonitis. However, the mechanism by which treatment of hypokalemia prevents peritonitis is unknown. Currently, the relationship between gastric acid suppression therapy and peritonitis in elderly patients is debatable, with no evidence to strongly recommend uniform discontinuation of gastric acid suppression therapy. Exit-site infection (ESI) is a major risk factor for the development of peritonitis, and appropriate prevention and management of ESI may reduce infection-related hospitalizations in PD patients. Currently, no randomized, controlled trials have verified the effectiveness of antibiotic application for ESI in Japan, but results from other countries are awaited. In assisted PD, it is extremely important that family members, caregivers, and nurses who support the procedure receive sufficient education and training from medical professionals familiar with PD. Early detection and treatment of PD-related infections are required because the risk of death increases in elderly patients.

Abstract
Aim This study aims to assess the extent of social alienation in patients undergoing peritoneal dialysis and examine how personal mastery and perceived social support mediate the association between emotional intelligence and social alienation in this patient population. Methods This study adopts a cross-sectional survey design. A total of 192 patients were recruited from a tertiary hospital located in Henan Province, China, using a convenience sampling method. We have developed a structural equation model to investigate the mediating influence of personal mastery and perceived social support on the emotional intelligence and social alienation of patients undergoing Peritoneal dialysis. Results Peritoneal patients exhibited an social alienation score of 42.01 ± 3.15. Elevated EI levels (coefficient = -0.616, p < 0.001) were significantly correlated with reduced social alienation. The mediation model demonstrated that personal mastery and perceived social support fully mediated the impact of emotional intelligence on social alienation. Conclusion The social alienation of peritoneal dialysis patients is serious, and healthcare professionals should pay attention to patients' social alienation, improve patients' emotional intelligence through relevant interventions, increase personal mastery and perceived social support, and finally reduce social alienation.

Abstract
Key Points This is the largest analysis of incident automated peritoneal dialysis (PD) prescriptions conducted in the United States to date. There was limited variability of automated PD prescriptions across the first 4 months of therapy. PD prescriptions tailored to meet the dialysis needs and lifestyle of patients may make PD a more attractive choice and increase longevity on PD. Background Changes in health care policies and recognition of patient benefit have contributed to increases in home-based dialysis, including peritoneal dialysis (PD). Frequent monitoring and early individualization of PD prescriptions are key prerequisites for the delivery of high-quality PD. The present analysis aimed to assess variations in PD prescriptions among incident automated PD (APD) patients who remain on PD for 120+ days. Methods This retrospective analysis examined data from patients within a large dialysis organization that initiated PD with APD between 2015 and 2019. PD prescription data were described by calendar year, timing of PD, and residual renal function categories. Changes in prescriptions from PD initiation (day 1) to day 120 were assessed descriptively. Results The cohort included 11,659 patients. The mean age at PD initiation increased from 2015 (56 [15] years) through 2019 (58 [15] years), whereas most other variables demonstrated no clear temporal change. Most patients (86%) had nighttime PD prescribed, with an average of 4.9 (1.3) cycles per day, a mean total treatment volume of 9.3 (2.5) L, and a median daily total dwell time of 7 (6–9.5) hours. Relative to day 1 nighttime prescriptions, there were (1 ) small increases in the proportion of patients receiving three or fewer cycles per day and those receiving 6+ cycles per day, (2 ) a 100 ml mean increase in fill volume per exchange, and (3 ) a mean 0.5 L increase in total nighttime treatment volume at day 120. When changes in nighttime APD prescriptions were examined at the patient level, 49% of patients had day 120 prescriptions that were unchanged from their initial prescription. Conclusions In the largest analysis of incident APD prescriptions conducted in the United States to date, most patients were prescribed nocturnal PD only with limited variability across the first 4 months of therapy.

Abstract
PURPOSE Incremental peritoneal dialysis (IPD) could decrease unfavorable glucose exposure results and preserve (RKF). However, there is no standardization of dialysis prescriptions for patients undergoing IPD. We designed a prospective observational multi-center study with a standardized IPD prescription to evaluate the effect of IPD on RKF, metabolic alterations, blood pressure control, and adverse outcomes. METHODS All patients used low GDP product (GDP) neutral pH solutions in both the incremental continuous ambulatory peritoneal dialysis (ICAPD) group and the retrospective standard PD (sPD) group. IPD patients started treatment with three daily exchanges five days a week. Control-group patients performed four changes per day, seven days a week. RESULTS A total of 94 patients (47 IPD and 47 sPD) were included in this study. The small-solute clearance and mean blood pressures were similar between both groups during follow-up. The weekly mean glucose exposure was significantly higher in sPD group than IPD during the follow-up (p < 0.001). The patients with sPD required more phosphate-binding medications compared to the IPD group (p = 0.05). The rates of peritonitis, tunnel infection, and hospitalization frequencies were similar between groups. Patients in the sPD group experienced more episodes of hypervolemia compared to the IPD group (p = 0.007). The slope in RKF in the 6th month was significantly higher in the sPD group compared to the IPD group (65% vs. 95%, p = 0.001). CONCLUSION IPD could be a rational dialysis method and provide non-inferior dialysis adequacy compared to full-dose PD. This regimen may contribute to preserving RKF for a longer period.

Abstract
OBJECTIVE It remains ambiguous as to whether the status of trace elements would affect their related enzyme activities toward defending a possible higher oxidative stress in patients receiving peritoneal dialysis (PD) or hemodialysis (HD) treatment. We investigated copper (Cu), zinc (Zn), and selenium (Se) status in patients receiving PD or HD treatments and further determined the association of these trace elements with their related antioxidant capacities in those patients. METHODS Sixty PD and 80 HD patients before and after HD treatment had their blood drawn. Demographic, clinical, and 24-hour diet recall data were recorded and collected. Plasma trace elements, oxidative stress indicators, and antioxidant enzyme activities were measured. RESULTS Patients receiving PD or HD treatments experienced similar Zn and Cu intakes. PD and HD patients displayed adequate mean plasma Cu, Zn, and Se levels. Patients receiving PD treatment showed significantly higher levels of Cu, Zn, advanced oxidation protein products (AOPPs), and superoxide dismutase (SOD) activity, but had significantly lower levels of Se and total antioxidant capacity when compared to levels in the HD patients at the pre-HD session. The levels of 3 trace elements and AOPP increased significantly, while the levels of glutathione (GSH), oxidized glutathione (GSSG), GPx, and SOD activities decreased significantly after receiving HD treatment than did the levels in the pre-HD session. Plasma Cu, Se, and Zn levels had a different correlation with plasma AOPP level, GPx, and SOD activities during PD, pre- or post-HD sessions. Plasma Cu, Zn, and Se levels did not have any association with their associated enzyme activities in patients with PD, while plasma Cu and Zn levels may have influenced SOD activity in HD patients. CONCLUSIONS An adequate Cu, Zn, and Se status is required in order to help their associated enzyme activity cope with increased oxidative stress during PD or HD sessions.

Abstract
Use of peritoneal dialysis and home haemodialysis remains low in Europe, with the highest use in Scandinavian countries and the lowest in Eastern and Central Europe despite the advantages for people on dialysis and economic advantages for healthcare systems. This is partly due to the impact of the haemodialysis industry resulting in proliferation of haemodialysis units and nephrologist reimbursement related to use of haemodialysis. Equally important is the bias against home dialysis at both clinician and healthcare system levels. The underlying causes of this bias are discussed in relation to a mechanistic view of the human body, lack of compassion, failure to adjust dialysis provision for older age and frailty, proliferation of small dialysis centres, and complexity of decision-making and clinical care. For home dialysis to flourish, we need to foster a change in attitude to and vision of the aims of healthcare so that enabling meaningful activities of people requiring dialysis, as explored in the Standardized Outcomes in Nephrology initiative, rather than achieving biological numbers become the focus of care delivery.

Abstract
Traditionally, dialysis adequacy has been assessed primarily by determining the clearance of a single small solute, urea. Nevertheless, it has become increasingly evident that numerous other factors play a crucial role in the overall well-being, outcomes and quality of life of dialysis patients. Consequently, in recent years, there has been a notable paradigm shift in guidelines and recommendations regarding dialysis adequacy. This shift represents a departure from a narrow focus only on the removal of specific toxins, embracing a more holistic, person-centered approach. This new perspective underscores the critical importance of improving the well-being of individuals undergoing dialysis while simultaneously minimizing the overall treatment burden. It is based on a double focus on both clinical outcomes and a comprehensive patient experience. To achieve this, a person-centered approach must be embraced when devising care strategies for each individual. This requires a close collaboration between the healthcare team and the patient, facilitating an in-depth understanding of the patient's unique goals, priorities and preferences while striving for the highest quality of care during treatment. The aim of this publication is to address the existing evidence on this all-encompassing approach to treatment care for patients undergoing peritoneal dialysis and provide a concise overview to promote a deeper understanding of this person-centered approach.

Abstract
Chronic kidney disease (CKD) is a global health concern affecting approximately one billion individuals worldwide. End-stage kidney disease (ESKD), the most severe form of CKD, is often accompanied by anemia. Peritoneal dialysis (PD), a common treatment for ESKD, utilizes the peritoneum for solute transfer but is associated with complications including protein loss, including transferrin (Tf) a key protein involved in iron transport. This study investigated Tf characteristics in ESKD patients compared to healthy individuals using lectin microarray, spectroscopic techniques and immunocytochemical analysis to assess Tf interaction with transferrin receptors (TfRs). ESKD patients exhibited altered Tf glycosylation patterns, evidenced by significant changes in lectin reactivity compared to healthy controls. However, structural analyses revealed no significant differences in the Tf secondary or tertiary structures between the two groups. A functional analysis demonstrated comparable Tf-TfR interaction in both PD and healthy samples. Despite significant alterations in Tf glycosylation, structural integrity and Tf-TfR interaction remained preserved in PD patients. These findings suggest that while glycosylation changes may influence iron metabolism, they do not impair Tf function. The study highlights the importance of a glucose-free dialysis solutions in managing anemia exacerbation in PD patients with poorly controlled anemia, potentially offering a targeted therapeutic approach to improve patient outcomes.

Abstract
Kidney failure has a negative impact on both children and families' quality of life (QOL). We evaluated the burden of home peritoneal dialysis (PD) using two local questionnaires and the French version of PedsQL3.0 end-stage kidney disease module and family impact module. Data are expressed as median (min-max). We reviewed the charts of 12 patients, at a median age of 8.8 (1.2-16.7) years, undergoing maintenance PD for 8 (1-42) months. Parathyroid hormone and haemoglobin levels were 215 (17-606) ng/L and 117 (104-141) g/L, respectively. Patients were taking 7 (3-10) different medications, corresponding to 9 (4-17) doses per day. The PD fluid volume per cycle was 1035 (723-1348) mL/m2 with a dwell duration of 75 (60-90) min and 6 (5-9) cycles per night. On a 2-week period, there were 2 (1-11) alarms per night resulting in 2 (0-8) times waking up and getting out of the bed for the parent(s); families were late 1 (0-11) times for school or parent's work. The time spent to connect and disconnect the cycler to the patient was 30 (12-46) min per day. QOL score on child self-report was correlated positively with weight percentile for age (R = 0.857; p = 0.014) and negatively with the number of siblings (R = -0.917; p = 0.004). The children QOL was evaluated higher by self-report scores: 77 (59-87) than by parent-proxy report scores: 53 (29-74), respectively (p = 0.028). PD children/teenagers and their caregivers can feel overwhelmed by the daily home therapy. Self-report and parent-proxy report QOL were significantly different, and it is questionable whether the parent-proxy report QOL relies rather on parents' own QOL.

Abstract
Writing a home hemodialysis (HD) prescription is a complex, multifactorial process that requires the incorporation of patient values, preferences, and lifestyle. Knowledge of the different options available for home HD modality (conventional, nocturnal, short daily, and alternate nightly) is also important when customizing a prescription. Finally, an understanding of the different home HD machines currently approved for use at home and their different attributes and limitations helps guide providers when formulating their prescriptions. In this review article, we set out to address these different aspects to help guide providers in providing a patient-centered home HD approach.

Abstract
BACKGROUND Peritoneal dialysis (PD) is one type of renal replacement therapy. If patients have problems during the dialysis process, healthcare providers may not be able assist the patients immediately. mHealth can provide patients with information and help them to solve problems in real-time, potentially increasing their willingness to choose PD. OBJECTIVE The objectives of this study were to conduct a comprehensive review of free mobile applications for patients with PD on the Internet and to recommend suitable mobile applications to facilitate patient self-management and health. METHODS We conducted a systematic search for PD mobile applications on Google Play and the Apple iTunes Store from 3 to 16 June 2023. RESULTS A total of 828 identifiable mobile applications were initially identified, and ultimately, 21 met the inclusion criteria. The Mobile App Rating Scale (MARS) assessment of the applications revealed the highest score in the functionality domain, followed by the aesthetics, information, app-specific, subjective quality, and engagement domains, respectively. In the comprehensive self-management of PD, the highest percentage was related to disease-related information. CONCLUSION The findings of this study suggest that some applications, with the highest quality, can be recommended to patients for use in English or traditional Chinese.

Abstract
Peritoneal dialysis (PD) enables people to have a home-based therapy, permitting greater autonomy for individuals along with enhanced treatment satisfaction compared with in-center dialysis care. The burden of treatment on PD, however, remains considerable and underpins the need for person-centered care. This reflects the need to address the patient as a person with needs and preferences beyond just the medical perspective. Shared decision making is central to the recent International Society for Peritoneal Dialysis recommendations for prescribing PD, balancing the potential benefits of PD on patient well-being with the burden associated with treatment. This review considers the role of high-quality goal-directed prescribing, incremental dialysis, and remote patient monitoring in reducing the burden of dialysis, including an approach to implementing incremental PD. Although patient-related outcomes are important in assessing the response to treatment and, particularly life participation, the corollary of dialysis burden, there are no clear routes to the clinical implementation of patient-related outcome measures. Delivering person-centered care is dependent on treating people both as individuals and as equal partners in their care.

Abstract
INTRODUCTION AND OBJECTIVES Diabetes, dyslipidemia, older age, gender, urinary tract infections, and recent antibiotic intake have been associated with a decrease in the urobiome richness and other fluctuations in this microbiome. Gut and blood microbiome have been reported to be altered in patients with chronic kidney disease (CKD), and specifically in peritoneal dialysis (PD) patients. Still, there are currently no studies describing the urogenital microbiome in CKD-PD patients. In this study we characterized the urobiome profile in 46 PD patients and analyzed its clinical and inflammatory parameters. MATERIALS AND METHODS Mid-stream urine, fecal and blood samples were collected from 46 patients undergoing PD at Centro Hospitalar Universitário de São João (CHUSJ) in Porto, Portugal. Exclusion criteria were age under 18 years old, inability to give informed consent, history of infection in the last three months, and antibiotic intake in the last three months. The microbiome communities were analyzed by amplification and sequencing of the V3-V4 region of the bacterial 16S rRNA gene. Correlations with the patients' clinical data and inflammatory profile were performed. RESULTS CKD-PD patients presented a unique urobiome profile dominated by Bacillota, Actinomycetota and Pseudomonadota and characterized by a lower Shannon diversity than fecal and blood microbiome. The taxonomic profiles of urogenital samples were organized in multiple subtypes dominated by populations of Lactobacillus, Staphylococcus, Streptococcus, Gardnerella, Prevotella, Escherichia-Shigella, being similar to other non-PD-CKD patients. Gender, sCD14, residual diuresis and history of peritonitis were significantly associated to variations in the urobiome. Although not reaching statistical significance, diabetes and the time on PD also showed association with particular taxonomic groups. Depletion of Gardnerella, Staphylococcus, Corynebacterium, Lactobacillus or Dermabacter populations correlated with CKD-PD patients with history of diabetes, history of peritonitis and altered levels of sCD14. CONCLUSIONS Our results highlight urogenital microbiome as a potential partner and/or marker in the overall health state of CKD-PD patients.

Abstract
BackgroundProtein restriction has been extended to stage 3 chronic kidney disease (CKD) regardless of age in the latest K-DOQI guidelines for the dietary management of patients with CKD. However, in elderly CKD patients there is a tendency to a spontaneous reduction in protein and energy intake that may impair the overall nutritional status. The aim of our study is to assess whether there are differences in malnutrition, exercise capacity and inflammatory status in elderly CKD patients with spontaneously low protein intake (sLPI) compared with patients with normal protein intake (NPI).MethodsWe performed a cross-sectional analysis of 123 incident patients. Malnutrition was assessed using Malnutrition Inflammation Score (MIS) and serum markers; As for physical performance, we used Short Physical Performance Battery (SPPB) and handgrip strength.ResultsWe found that in older patients with advanced CKD, as many as 68% had low spontaneous protein intake, and they were more malnourished evaluated with MIS (25% vs. 10%, p = 0.033), protein-energy wasting (PEW) (43% vs. 14%, p = 0.002) and nPCR (0.63[0.51–0.69] vs. 0.95[0.87–1.1], p < 0.0001). They also had worse body composition, in terms of lower mid-arm muscular circumference (MAMC), fat tissue index (FTI) and higher overhydration (OH). sLPI patients also had higher levels of IL6 (4.6[2.9–8.9] vs. 2.8[0.8–5.1], p = 0.002). Moreover, sLPI patients were frailer (33% vs. 24%, p = 0.037) and had poorer physical performance especially when assessed with (SPPB) (7[5–9] vs. 9[7–10], p = 0.004) and gait test time (6.08 + 2 vs. 7.22 + 2.7, p = 0.04). sLPI was associated with lower physical performance [SPPB OR, 0.79 (0.46–0.97), p = 0.046] and malnutrition [MIS 1.6 (1.05–3.5), p = 0.041] independently from patients’ age and eGFR.ConclusionWe found that in older patients with advanced CKD, up to 68% had low spontaneous protein intake and were frailer, more malnourished and with lower physical performance. These findings emphasize the importance of assessing patients’ needs, and personalized approaches with individual risk–benefit assessments should be sought. To achieve the best possible outcomes, targeted interventions should use all available tools.

Abstract
A healthy and functional peritoneal membrane is key to achieving sufficient ultrafiltration and restoring fluid balance, a major component of high-quality prescription in patients treated with peritoneal dialysis (PD). Variability in membrane function at the start of PD or changes over time on treatment influence dialysis prescription and outcomes, and dysfunction of the peritoneal membrane contributes to fluid overload and associated complications. In this review, we summarize the current knowledge about the structure, function, and pathophysiology of the peritoneal membrane with a focus on clinical implications for patient-centered care. We also discuss the molecular and genetic mechanisms of solute and water transport across the peritoneal membrane, including the role of aquaporin water channels in crystalloid versus colloid osmosis; why and how to assess membrane function using peritoneal equilibration tests; the etiologies of membrane dysfunction and their specific management; and the effect of genetic variation on membrane function and outcomes in patients treated with PD. This review also identifies the gaps in current knowledge and perspectives for future research to improve our understanding of the peritoneal membrane and, ultimately, the care of patients treated with PD.

Effects of Steady Glucose Concentration Peritoneal Dialysis on Ultrafiltration Volume and Sodium Removal: A Pilot Crossover Trial. Clin J Am Soc Nephrol 2024; 19:224-232. [PMID: 37902732 PMCID: PMC10861104 DOI: 10.2215/cjn.0000000000000342] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 10/23/2023] [Indexed: 10/31/2023]
Abstract
BACKGROUND Volume overload is common in patients treated with peritoneal dialysis (PD) and is associated with poor clinical outcome. Steady concentration PD is where a continuous glucose infusion maintains the intraperitoneal glucose concentration and as a result provides continuous ultrafiltration throughout the dwell. The primary objective of this study was to investigate the ultrafiltration rate and glucose ultrafiltration efficiency for steady concentration PD in comparison with a standard continuous ambulatory PD (CAPD) dwell, using the novel Carry Life UF device. METHODS Eight stable patients treated with PD (six fast and two fast average transporters) were investigated four times: a standard 4-hour CAPD dwell with 2 L of 2.5% dextrose solution as control and three 5-hour steady concentration PD treatments (glucose dose 11, 14, 20 g/h, initial fill 1.5 L of 1.5% dextrose solution). All investigations were preceded by an overnight 2 L 7.5% icodextrin dwell. RESULTS Intraperitoneal glucose concentration increased during the first 1-2 hours of the steady concentration PD treatments and remained stable thereafter. Ultrafiltration rates were significantly higher with steady concentration PD treatments (124±49, 146±63, and 168±78 mL/h with 11, 14, and 20 g/h, respectively, versus 40±60 mL/h with the control dwell). Sodium removal and glucose ultrafiltration efficiency (ultrafiltration volume/gram glucose uptake) were significantly higher with steady concentration PD treatments versus the control dwell, where the 11 g/h glucose dose was most efficient. CONCLUSIONS Steady concentration PD performed with the Carry Life UF device resulted in higher ultrafiltration rates, more efficient use of glucose (increased ultrafiltration volume/gram glucose absorbed), and greater sodium removal compared with a standard 2.5% dextrose CAPD dwell.

Abstract
BACKGROUND Peritoneal dialysis (PD) solutions containing low levels of glucose degradation products (GDPs) are associated with attenuation of peritoneal membrane injury and vascular complications. However, clinical benefits associated with neutral-pH, low-GDP (N-pH/L-GDP) solutions remain unclear. METHODS Using data from the Australia and New Zealand Dialysis and Transplant Registry, we examined the associations between N-pH/L-GDP solutions and all-cause mortality, cause-specific mortality, transfer to haemodialysis (HD) for ≥30 days and PD peritonitis in adult incident PD patients in Australia and New Zealand between 1 January 2005 and 31 December 2020 using adjusted Cox regression analyses. RESULTS Of 12 814 incident PD patients, 2282 (18%) were on N-pH/L-GDP solutions. The proportion of patients on N-pH/L-GDP solutions each year increased from 11% in 2005 to 33% in 2017. During the study period, 5330 (42%) patients died, 4977 (39%) experienced transfer to HD and 5502 (43%) experienced PD peritonitis. Compared with the use of conventional solutions only, the use of any form of N-pH/L-GDP solution was associated with reduced risks of all-cause mortality {adjusted hazard ratio [aHR] 0.67 [95% confidence interval (CI) 0.61-0.74]}, cardiovascular mortality [aHR 0.65 (95% CI 0.56-0.77)], infection-related mortality [aHR 0.62 (95% CI 0.47-0.83)] and transfer to HD [aHR 0.79 (95% CI 0.72-0.86)] but an increased risk of PD peritonitis [aHR 1.16 (95% CI 1.07-1.26)]. CONCLUSIONS Patients who received N-pH/L-GDP solutions had decreased risks of all-cause and cause-specific mortality despite an increased risk of PD peritonitis. Studies assessing the causal relationships are warranted to determine the clinical benefits of N-pH/L-GDP solutions.

Abstract
There have been significant advances in the understanding of peritoneal dialysis (PD) in the last 40 years, and uptake of PD as a modality of kidney replacement therapy is increasing worldwide. PD fluids, therefore, remains the lifeline for patients on this treatment. Developing these fluids to be efficacious in solute clearance and ultrafiltration, with minimal adverse consequences to peritoneal membrane health and systemic effects is a key requirement. Since the first PD fluid produced in 1959, modifications to PD fluids have been made. Nonetheless, the search for that ideal PD fluid remains elusive. Understanding the components of PD fluids is a key aspect of optimizing the successful delivery of PD, allowing for individualized PD prescription. Glucose remains an integral component of PD fluids; however, its deleterious effects continue to be the impetus for the search of an alternative osmotic agent, and icodextrin remains the main alternative. More biocompatible PD fluids have been developed and have shown benefits in preserving residual kidney function. However, high cost and reduced accessibility remain deterrents to its widespread clinical use in many countries. Large-scale clinical trials are necessary and very much awaited to improve the narrow spectrum of PD fluids available for clinical use.

Abstract
INTRODUCTION We aimed to determine the correlation between the serum urea-to-creatinine ratio and residual kidney function (RKF) in patients undergoing peritoneal dialysis (PD), as well as its predictive value for PD-related outcomes. METHODS This study included a cross-sectional study to assess the correlation between serum urea-to-creatinine ratio and RKF in 50 patients on PD and a retrospective cohort study to assess the association between serum urea-to-creatinine ratio and PD-related outcomes in 122 patients who initiated PD. RESULTS Serum urea-to-creatinine ratios had significant positive correlations with renal Kt/V and creatinine clearance values (r = 0.60, p < 0.001 and r = 0.61, p < 0.001, respectively). Additionally, serum urea-to-creatinine ratio was significantly associated with a lower risk of transfer to hemodialysis or PD/hemodialysis hybrid therapy (hazard ratio: 0.84, 95% confidence interval: 0.75-0.95). CONCLUSION The serum urea-to-creatinine ratio can be an indicator of RKF and a prognostic factor in patients undergoing PD.

Abstract
Advocacy and policy change are powerful levers to improve quality of care and better support patients on home dialysis. While the kidney community increasingly recognizes the value of home dialysis as an option for patients who prioritize independence and flexibility, only a minority of patients dialyze at home in the United States. Complex system-level factors have restricted further growth in home dialysis modalities, including limited infrastructure, insufficient staff for patient education and training, patient-specific barriers, and suboptimal physician expertise. In this article, we outline trends in home dialysis use, review our evolving understanding of what constitutes high-quality care for the home dialysis population (as well as how this can be measured), and discuss policy and advocacy efforts that continue to shape the care of US patients and compare them with experiences in other countries. We conclude by discussing future directions for quality and advocacy efforts.

Abstract
BACKGROUND Peritoneal dialysis provides several benefits for patients and should be offered as first line kidney replacement therapy, particularly for fragile patients. Limitation to self-care drove assisted peritoneal dialysis to evolve from family-based care to institutional programs, with specialized care givers. Some European countries have mastered this, while others are still bound by the availability of a volunteer to become responsible for treatment. METHODS A group of leading nephrologists from 13 European countries integrated real-life application of such therapy, highlighting barriers, lessons learned and practical solutions. The objective of this work is to share and summarize several different approaches, with their intrinsic difficulties and solutions, which might helpperitoneal dialysis units to develop and offer assisted peritoneal dialysis. RESULTS Assisted peritoneal dialysis does not mean 4 continuous ambulatory peritoneal dialysis exchanges, 7 days/week, nor does it exclude cycler. Many different prescriptions might work for our patients. Tailoring PD prescription to residual kidney function, thereby maintaining small solute clearance, reduces dialysis burden and is associated with higher technique survival. Assisted peritoneal dialysis does not mean assistance will be needed permanently, it can be a transitional stage towards individual or caregiver autonomy. Private care agencies can be used to provide assistance; other options may involve implementing PD training programs for the staff of nursing homes or convalescence units. Social partners may be interested in participating in smaller initiatives or for limited time periods. CONCLUSION Assisted peritoneal dialysis is a valid technique, which should be expanded. In countries without structural models of assisted peritoneal dialysis, active involvement by the nephrologist is needed in order for it to become a reality.

Abstract
ABSTRACT Peritoneal dialysis (PD) is now commonly prescribed to achieve target clearances for urea or creatinine. The International Society for Peritoneal Dialysis has proposed however that such targets should no longer be imposed. The Society's new guidelines suggest rather that the PD prescription should be adjusted to achieve well-being in individual patients. The relaxation of treatment targets could allow increased use of PD. Measurement of solute levels in patients receiving dialysis individualized to relieve uremic symptoms could also help us identify the solutes responsible for those symptoms and then devise new means to limit their accumulation. This possibility has prompted us to review the extent to which different uremic solutes are removed by PD.

Abstract
Background An aging population living with chronic kidney disease and progressing to kidney failure, subsequently receiving peritoneal dialysis (PD) is growing. A significant proportion of these patients are also living with multi-morbidities and some degree of frailty. Recent practice recommendations from the International Society of Peritoneal Dialysis advocate for high-quality, goal-directed PD prescription, and the Standardized Outcomes of Nephrology-PD initiative emphasized the need for an individualized, goal-based care approach in all patients receiving PD treatment. In older patients, this approach to PD care is even more important. A frailty screening assessment, followed by a comprehensive geriatric assessment (CGA) prior to PD initiation and when dictated by change in relevant circumstances is paramount in tailoring PD care and prescription according to the needs, life goals, as well as clinical status of older patients with kidney failure. Summary Our review aimed to summarize the different dimensions to be taken into account when delivering PD care to the older patient - from frailty screening and CGA in older patients receiving PD to employing a personalized, goal-directed PD prescription strategy, to preserving residual kidney function, optimizing blood pressure (BP) control, and managing anemia, to addressing symptom burden, to managing nutritional intake and promoting physical exercise, and to explore telehealth opportunities for the older PD population. Key Messages What matters most to older PD patients may not be simply extending survival, but more importantly, to be living comfortably on PD treatment with minimal symptom burden in a home environment and to minimize treatment complications.

Abstract
INTRODUCTION Dialysis is complicated in the setting of acute brain injury (ABI) due to several factors including acute solute shifts, acid base changes, need for anticoagulation, and changes in intracranial pressure. For these reasons, continuous renal replacement therapy (CRRT) is often the chosen modality for renal replacement needs in these patients. Peritoneal dialysis (PD) is less discussed but shares many of the benefits often attributed to CRRT. We describe, from both nephrology and neurosurgical perspectives, a case successfully managed with PD. CASE A 25-year-old male with history of end-stage kidney disease (ESKD) secondary to focal segmental glomerulosclerosis on continuous cycling PD for 5 years presented to the hospital with headache and altered mental status. Initial imaging revealed a large intraventricular hemorrhage extending to the fourth ventricle. He underwent an emergent right depressive hemicraniectomy and clot evacuation. Post-operative imaging revealed worsening cerebral edema, intraventricular hemorrhage, and hydrocephalus. The decision was made to continue PD, noting that it retains many of the benefits of CRRT (which it is in fact, a form of) which he tolerated well until the need for a percutaneous gastrostomy tube arose. He was transiently transitioned to hemodialysis but returned to PD once his gastrostomy healed. He continued PD for 1 year without complication and eventually received a kidney transplant. DISCUSSION In managing patients with ABI undergoing dialysis, a number of considerations must be undertaken including avoidance of hypotension to maintain cerebral perfusion pressure and minimize ischemia reperfusion injury, avoidance of anticoagulants that can precipitate or worsen bleeding, the potential for cerebral edema due to rapid solute clearance and osmotic dissipation of therapeutic hypernatremia, and the mitigation of intracellular acidosis from bicarbonate delivery. Although underutilized, PD may potentially serve as a viable option for dialysis in the setting of ABI as demonstrated by the case presented.

Abstract
INTRODUCTION Coagulation system dysfunction is associated with adverse outcomes of peritoneal dialysis (PD) and bacterial infection. We investigated the association between coagulation system and treatment failure of peritoneal dialysis-related peritonitis (PDRP). METHODS We collected records of patients aged ≥18 years with PDRP. PDRP episodes were divided into: shortened activated partial thromboplastin time (APTT) group and prolonged APTT group, low D-dimer (DD) group and high DD group. The baseline characteristics of the groups were collected and compared. The association between APTT, DD and treatment failure of PDRP was analyzed using logistic regression analysis. RESULTS Thirty episodes of treatment failure were observed in 110 episodes of PDRP in our study. After adjusting for variables, prolonged APTT (OR = 1.166 [1.049-1.296], p = 0.004) or high level of DD (OR = 1.374 [1.057-1.787], p = 0.017) was associated with treatment failure of PDRP. CONCLUSION Prolonged baseline APTT or high level of DD increased the risk of treatment failure of PDRP.

Abstract
BACKGROUND Incremental peritoneal dialysis (PD), defined as less than Full-dose PD prescription, has several possible merits, including better preservation of residual kidney function (RKF), lower peritoneal glucose exposure and reduced risk of peritonitis. The aims of this study were to analyse the association of Incremental and Full-dose PD strategy with RKF and urine volume (UV) decline in patients commencing PD. METHODS Incident PD patients who participated in the balANZ randomised controlled trial (RCT) (2004-2010) and had at least one post-baseline RKF and UV measurement was included in this study. Patients receiving <56 L/week and ≥56 L/week of PD fluid at PD commencement were classified as Incremental and Full-dose PD, respectively. An alternative cut-point of 42 L/week was used in a sensitivity analysis. The primary and secondary outcomes were changes in measured RKF and daily UV, respectively. RESULTS The study included 154 patients (mean age 57.9 ± 14.1 years, 44% female, 34% diabetic, mean follow-up 19.5 ± 6.6 months). Incremental and Full-dose PD was commenced by 45 (29.2%) and 109 (70.8%) participants, respectively. RKF declined in the Incremental group from 7.9 ± 3.2 mL/min/1.73 m2 at baseline to 3.2 ± 2.9 mL/min/1.73 m2 at 24 months (p < 0.001), and in the Full-dose PD group from 7.3 ± 2.7 mL/min/1.73 m2 at baseline to 3.4 ± 2.8 mL/min/1.73 m2 at 24 months (p < 0.001). There was no difference in the slope of RKF decline between Incremental and Full-dose PD (p = 0.78). UV declined from 1.81 ± 0.73 L/day at baseline to 0.64 ± 0.63 L/day at 24 months in the Incremental PD group (p < 0.001) and from 1.38 ± 0.61 L/day to 0.71 ± 0.46 L/day in the Full-dose PD group (p < 0.001). There was no difference in the slope of UV decline between Incremental and Full-dose PD (p = 0.18). CONCLUSIONS Compared with Full-dose PD start, Incremental PD start is associated with similar declines in RKF and UV.
