Spiritual well-being (SWB), an individual's understanding of the meaning and purpose of life, may help patients with chronic or terminal illnesses cope with their diseases. This study aimed to assess SWB in patients on peritoneal dialysis (PD), as well as its relationship with patient characteristics and patient-reported outcomes (PRO).The data were obtained from questionnaires that formed part of the PD Outcomes and Practice Patterns Study (PDOPPS). Measures used in this study were SWB scores derived from the WHO quality of life, spirituality, religiousness and personal beliefs (WHOQOL-SRPB) tool including 32 items from eight facets; physical (PCS) and mental component summary (MCS) scores of the 12-Item Short-Form Health Survey (SF-12), Center of Epidemiologic Studies Depression Scale-10 (CES-D-10) scores, burden of kidney disease scores and functional status scores.Overall, 529 out of 848 participants (62%) completely responded to the questionnaires and were included in the analysis. Over two-thirds of PD patients (70%) had moderate or higher SWB scores. The SWB scores were significantly lower in patients with age 65 years and unemployed status. SWB scores positively correlated with higher PCS, MCS, burden of kidney disease scores and functional status scores, while negatively correlated with depression scores by CES-D-10 scale. Patients who reported significant depressive symptoms (CES-D-10 score ≥ 10) had significantly lower SWB scores.Better SWB was significantly associated with better health-related QOL (HRQOL) and the absence of depressive symptoms. SWB may be an essential consideration in the delivery of high-quality PD.

Background: Although caregivers allow peritoneal dialysis (PD) patients with disabilities the opportunity to perform PD, it is crucial to clarify the safety and effectiveness of assisted PD performed by caregivers compared to self-PD. Methods: PD patients from 22 PD centres in Thailand were prospectively followed in the Peritoneal Dialysis Outcomes and Practice Patterns Study during 2016–2017. Patients receiving assisted PD performed by caregivers were matched 1:1 with self-PD patients using propensity scores calculated by logistic regression. The associations between assisted PD and risk of mortality, peritonitis and permanent transfer to haemodialysis (HD) were assessed by multivariable competing risk regression. Results: Of 778 eligible patients, 447 (57%) required assisted PD performed by caregivers. Most of the caregivers were family members (98%), while the rest were non-family paid caregivers (2%). Patient factors associated with assisted PD were older age, female gender, lower educational level, cardiovascular comorbidities, diabetes, automated PD modality, poorer functional status and lower blood chemistries (albumin, creatinine, sodium, potassium and phosphate). After 1:1 matching, the baseline characteristics were adequately matched, and 269 patients in each group were analysed. Compared with self-PD, assisted PD was significantly associated with an increased risk of all-cause mortality (adjusted sub-hazard ratio: 2.15, 95% confidence interval: 1.24–3.74). There were no differences in the occurrences of peritonitis and permanent HD transfer between the groups. Conclusions: Assisted PD was required by more than half of Thai PD patients and was independently associated with a higher mortality risk. This may reflect causal effect or confounding by indication.

The prevalence of kidney failure continues to rise globally. Dialysis is a treatment option for individuals with kidney failure; after the decision to initiate dialysis has been made, it is critical to involve individuals in the decision on which dialysis modality to choose. This review, based on evidence arising from the literature, examines the role of shared decision-making (SDM) in helping those with kidney failure to select a dialysis modality. SDM was found to lead to more people with kidney failure feeling satisfied with their choice of dialysis modality. Individuals with kidney failure must be cognizant that SDM is an active and iterative process, and their participation is essential for success in empowering them to make decisions on dialysis modality. The educational components of SDM must be easy to understand, high quality, unbiased, up to date, and targeted to the linguistic, educational, and cultural needs of the individual. All individuals with kidney failure should be encouraged to participate in SDM and should be involved in the design and implementation of SDM approaches.

Diagnosis of fluid overload (FO) in early stage is essential to manage fluid balance of patients with chronic kidney disease (CKD) and to prevent cardiovascular disease (CVD). However, the identification of fluid status in patients with CKD is largely dependent on the physician's clinical acumen. The ratio of fluid overload to extracellular volume (FO/ECV) has been used as a reference to assess fluid status. The primary aim of this study was to compare FO/ECV with other bioimpedance methods and clinical assessments in patients with CKD. Whole body ECV, intracellular volume (ICV), total body water (TBW), and calf normalized resistivity (CNR) were measured (Hydra 4200). Thresholds of FO utilizing CNR and ECV/TBW were derived by receiver operator characteristic (ROC) analysis based on data from pooled patients with CKD and healthy subjects (HSs). Clinical assessments of FO in patients with CKD were performed by nephrologists. Patients with CKD (stage 3 and stage 4) (

The coronavirus disease 2019 (COVID-19) pandemic has created unprecedented strain on health care resources in the United States. Initial reports of AKI rates from Wuhan, China ranged between 3% and 9%, although rates as high as 15% have been reported (1,2). For AKI requiring RRT, intermittent hemodialysis (HD) and continuous RRT (CRRT) have been mainstays of therapy in the United States. However, shortages in supplies, staffing, and available equipment among critically ill patients with COVID-19, particularly in the New York City area, have demanded alternative strategies such as acute peritoneal dialysis treatment for AKI (AKI-PD) that are being implemented. Here, we will review the rationale for the use of AKI-PD and describe potential advantages, criteria for patient selection, and practical considerations on the basis of initial experiences to consider when prescribing and delivering peritoneal dialysis (PD). PD was routine for AKI treatment worldwide well into the 1980s. However, by the 1990s with the development of the central venous catheter for HD and the advent of CRRT, PD became rarely used in higher-resource countries to treat adult patients with AKI (3). The utility and efficacy of PD to treat patients with AKI were re-examined after the publication of a series of articles from Brazil, including a randomized trial, demonstrating that PD provided acceptable care, was not inferior to daily HD in treating acutely ill patients with AKI in terms of patient mortality, and was associated with a shorter duration of AKI and need for RRT (4,5). These findings were confirmed in a randomized trial from Saudi Arabia comparing PD with hemodiafiltration (6). AKI-PD expanded dramatically in lower-resource countries with the advent of the Saving Young Lives Program in 2012, which promoted the use of PD because of minimal infrastructural requirements, including a lack of need for water …

Background: Peritoneal dialysis (PD) is a viable option for renal replacement therapy in acute kidney injury (AKI), especially in challenging times during disasters and pandemics when resources are limited. While PD techniques are well described, there is uncertainty about how to determine the amount of PD to be prescribed toward a target dose. The aim of this study is to derive practical equations to assist with the prescription of PD for AKI. Methods: Using established physiological principles behind PD clearance and membrane transport, a primary determinant of dose delivery, equations were mathematically derived to estimate dialysate volume required to achieve a target dose of PD. Results: The main derivative equation is VD = (1.2 × std- Kt/ V × TBW)/( tdwell + 4), where VD is the total dialysate volume per day, std- Kt/ V is the desired weekly dose, TBW is the total body water, and tdwell is the dwell time. VD can be expressed in terms of dwell volume, vdwell, by VD = (0.3 × std- Kt/ V × TBW) − (6 × vdwell). Two further equations were derived which directly describe the mathematical relationship between tdwell and vdwell. A calculator is included as an Online Supplementary Material. Conclusions: The equations are intended as a practical tool to estimate solute clearances and guide prescription of continuous PD. The estimated dialysate volume required for any dose target can be calculated from cycle duration or dwell volume. However, the exact target dose of PD is uncertain and should be adjusted according to the clinical circumstances and response to treatment. The equations presented in this article facilitate the adjustment of PD prescription toward the targeted solute clearance.

Background: Loop diuretics have well-described toxicities, and loss of response to these agents is common. Alternative strategies are needed for the maintenance of euvolemia in heart failure (HF). Nonrenal removal of sodium directly across the peritoneal membrane (direct sodium removal [DSR]) with a sodium-free osmotic solution should result in extraction of large quantities of sodium with limited off-target solute removal. Methods: This article describes the preclinical development and first-in-human proof of concept for DSR. Sodium-free 10% dextrose was used as the DSR solution. Porcine experiments were conducted to investigate the optimal dwell time, safety, and scalability and to determine the effect of experimental heart failure. In the human study, participants with end-stage renal disease on peritoneal dialysis (PD) underwent randomization and crossover to either a 2-hour dwell with 1 L DSR solution or standard PD solution (Dianeal 4.25% dextrose, Baxter). The primary end point was completion of the 2-hour dwell without significant discomfort or adverse events, and the secondary end point was difference in sodium removal between DSR and standard PD solution. Results: Porcine experiments revealed that 1 L DSR solution removed 4.1±0.4 g sodium in 2 hours with negligible off-target solute removal and overall stable serum electrolytes. Increasing the volume of DSR solution cycled across the peritoneum increased sodium removal and substantially decreased plasma volume ( P =0.005). In the setting of experimental heart failure with elevated right atrial pressure, sodium removal was ≈4 times greater than in healthy animals ( P P Conclusions: DSR was well tolerated in both animals and human subjects and produced substantially greater sodium removal than standard PD solution. Additional research evaluating the use of DSR as a method to prevent and treat hypervolemia in heart failure is warranted.

Prevention and early detection of kidney diseases in adults and children should be a priority for any government health department. This is particularly pertinent in the low-middle-income countries, mostly in Asia, Africa, Latin America, and the Caribbean, where up to 7 million people die because of lack of end-stage kidney disease treatment. The nephrology workforce (nurses, technicians, and doctors) is limited in these countries and expanding the size and expertise of the workforce is essential to permit expansion of treatment for both chronic kidney disease and end-stage kidney disease. To achieve this will require sustained action and commitment from governments, academic medical centers, local nephrology societies, and the international nephrology community.

Background: Current guidelines for the prescription of peritoneal dialysis dose rely on a single cut-off ‘minimal’ value of K t/ V. To apply this in the clinic, this requires an accurate estimation of V, the volume of urea distribution that equates to the total body water (TBW). This analysis sought to determine the accuracy to which V can be estimated. Methods: A literature search was undertaken of studies comparing TBW estimation using two or three of the following methods: isotopic dilution (gold standard), anthropometric equations (e.g. Watson formula) and bioimpedance analysis. Studies of healthy and dialysis populations of all ages were included. Mean differences and 95% limits of agreement (LOA) were extracted and pooled. Results: In 44 studies (31 including dialysis subjects), the between-method population means were typically within 1–1.5 L of each other, although larger bias was seen when applying anthropometric equations to different racial groups. However, the 95% LOA for all comparisons were consistently wide, typically ranging ±12–18% of the TBW. For a typical individual whose TBW is 35 L with a measured K t/ V of 1.7, this translates into a range of K t/ V 1.4–2.05. Conclusions: There are limitations to the accuracy of estimation of V which call into question the validity of applying a single threshold K t/ V value as indicative of adequate dialysis. This should be taken into account in guideline development such that if a target K t/ V was deemed appropriate that this should be expressed as a range; alternatively single targets should be avoided and dialysis dose should be determined according to patient need.

The goal of care of the peritoneal dialysis (PD) patient should be directed at adjusting therapy to maximize the patient’s health-related quality of life (HRQOL). Incorporating the routine assessments of HRQOL into the care of PD patients is important and should serve as an essential marker of the adequacy of dialysis and help the dialysis staff design the optimal treatment regimen for each patient. HRQOL is best assessed with patient-reported outcome measures (PROMs). How best to incorporate these PROMs into the routine care of the PD patient is not clear in terms of the best instruments to use, frequency of measurements, patient acceptability, and how to translate these assessments into improvements in patient care. Nevertheless, incorporating routine assessments of HRQOL into the care of PD patients is essential if the dialysis team is to provide optimal care; it is an area that is receiving increasing attention and is ripe for further study and investigation.

Heart failure (HF) is a major cause of morbidity and mortality. Extracorporeal (EC) therapy, including ultrafiltration (UF) and haemodialysis (HD), peritoneal dialysis (PD) and peritoneal ultrafiltration (PUF) are potential therapeutic options in diuretic-resistant states. This systematic review assessed outcomes of PD and compared the effects of PD to EC. A comprehensive search of major databases from 1966 to 2017 for studies utilising PD (or PUF) in diuretic-resistant HF was conducted, excluding studies involving patients with end-stage kidney disease. Data were extracted and combined using a random-effects model, expressed as odds ratio (OR). Thirty-one studies ( n = 902) were identified from 3195 citations. None were randomised trials. Survival was variable (0–100%) with a wide follow-up duration (36 h–10 years). With follow-up > 1 year, the overall mortality was 48.3%. Only four studies compared PD with EC. Survival was 42.1% with PD and 45.0% with EC; the pooled effect did not favour either (OR 0.80; 95% confidence interval (CI): 0.24–2.69; p = 0.710). Studies on PD in patients with HF reported several benefits. Left ventricular ejection fraction (LVEF) improved after PD (OR 3.76, 95%CI: 2.24–5.27; p < 0.001). Seven of nine studies saw LVEF increase by > 10%. Twenty-one studies reported the New York Heart Association status and 40–100% of the patients improved by ≥ 1 grade. Nine of 10 studies reported reductions in hospitalisation frequency and/or duration. When treated with PD, HF patients had fewer symptoms, lower hospital admissions and duration compared to diuretic therapy. However, there is inadequate evidence comparing PD versus UF or HD. Further studies comparing these modalities in diuretic-resistant HF should be conducted.

Background The clinical significance of accumulating toxic terminal metabolites such as oxalate in patients with kidney failure is not well understood. Methods To evaluate serum oxalate concentrations and risk of all-cause mortality and cardiovascular events in a cohort of patients with kidney failure requiring chronic dialysis, we performed a post-hoc analysis of the randomized German Diabetes Dialysis (4D) Study; this study included 1255 European patients on hemodialysis with diabetes followed-up for a median of 4 years. The results obtained via Cox proportional hazards models were confirmed by competing risk regression and restricted cubic spline modeling in the 4D Study cohort and validated in a separate cohort of 104 US patients on dialysis after a median follow-up of 2.5 years. Results A total of 1108 patients had baseline oxalate measurements, with a median oxalate concentration of 42.4 µM. During follow-up, 548 patients died, including 139 (25.4%) from sudden cardiac death. A total of 413 patients reached the primary composite cardiovascular end point (cardiac death, nonfatal myocardial infarction, and fatal or nonfatal stroke). Patients in the highest oxalate quartile (≥59.7 µM) had a 40% increased risk for cardiovascular events (adjusted hazard ratio [aHR], 1.40; 95% confidence interval [95% CI], 1.08 to 1.81) and a 62% increased risk of sudden cardiac death (aHR, 1.62; 95% CI, 1.03 to 2.56), compared with those in the lowest quartile (≤29.6 µM). The associations remained when accounting for competing risks and with oxalate as a continuous variable. Conclusions Elevated serum oxalate is a novel risk factor for cardiovascular events and sudden cardiac death in patients on dialysis. Further studies are warranted to test whether oxalate-lowering strategies improve cardiovascular mortality in patients on dialysis.

The development of peritoneal dialysis (PD) programmes in lower-resource countries is challenging. This article describes the learning points of establishing PD programmes in three countries in South Asia (Nepal, Sri Lanka and Pakistan). The key barriers identified were government support (financial), maintaining stable supply of PD fluids, lack of nephrologist and nurse expertise, nephrology community bias against PD, lack of nephrology trainee awareness and exposure to this modality. To overcome these barriers, a well-trained PD lead nephrologist (PD champion) is needed, who can advocate for this modality at government, professional and community levels. Ongoing educational programmes for doctors, nurses and patients are needed to sustain the PD programmes. Support from well-established PD centres and international organisations (International Society of Peritoneal Dialysis (ISPD), International Society of Nephrology (ISN), International Pediatric Nephrology Association (IPNA) are essential.

Background Acute kidney injury (AKI) is increasingly encountered in community settings and contributes to morbidity, mortality, and increased resource utilization worldwide. In low-resource settings, lack of awareness of and limited access to diagnostic and therapeutic interventions likely influence patient management. We evaluated the feasibility of the use of point-of-care (POC) serum creatinine and urine dipstick testing with an education and training program to optimize the identification and management of AKI in the community in 3 low-resource countries. Methods and findings Patients presenting to healthcare centers (HCCs) from 1 October 2016 to 29 September 2017 in the cities Cochabamba, Bolivia; Dharan, Nepal; and Blantyre, Malawi, were assessed utilizing a symptom-based risk score to identify patients at moderate to high AKI risk. POC testing for serum creatinine and urine dipstick at enrollment were utilized to classify these patients as having chronic kidney disease (CKD), acute kidney disease (AKD), or no kidney disease (NKD). Patients were followed for a maximum of 6 months with repeat POC testing. AKI development was assessed at 7 days, kidney recovery at 1 month, and progression to CKD and mortality at 3 and 6 months. Following an observation phase to establish baseline data, care providers and physicians in the HCCs were trained with a standardized protocol utilizing POC tests to evaluate and manage patients, guided by physicians in referral hospitals connected via mobile digital technology. We evaluated 3,577 patients, and 2,101 were enrolled: 978 in the observation phase and 1,123 in the intervention phase. Due to the high number of patients attending the centers daily, it was not feasible to screen all patients to assess the actual incidence of AKI. Of enrolled patients, 1,825/2,101 (87%) were adults, 1,117/2,101 (53%) were females, 399/2,101 (19%) were from Bolivia, 813/2,101 (39%) were from Malawi, and 889/2,101 (42%) were from Nepal. The age of enrolled patients ranged from 1 month to 96 years, with a mean of 43 years (SD 21) and a median of 43 years (IQR 27–62). Hypertension was the most common comorbidity (418/2,101; 20%). At enrollment, 197/2,101 (9.4%) had CKD, and 1,199/2,101 (57%) had AKD. AKI developed in 30% within 7 days. By 1 month, 268/978 (27%) patients in the observation phase and 203/1,123 (18%) in the intervention phase were lost to follow-up. In the intervention phase, more patients received fluids (observation 714/978 [73%] versus intervention 874/1,123 [78%]; 95% CI 0.63, 0.94; p = 0.012), hospitalization was reduced (observation 578/978 [59%] versus intervention 548/1,123 [49%]; 95% CI 0.55, 0.79; p < 0.001), and admitted patients with severe AKI did not show a significantly lower mortality during follow-up (observation 27/135 [20%] versus intervention 21/178 [11.8%]; 95% CI 0.98, 3.52; p = 0.057). Of 504 patients with kidney function assessed during the 6-month follow-up, de novo CKD arose in 79/484 (16.3%), with no difference between the observation and intervention phase (95% CI 0.91, 2.47; p = 0.101). Overall mortality was 273/2,101 (13%) and was highest in those who had CKD (24/106; 23%), followed by those with AKD (128/760; 17%), AKI (85/628; 14%), and NKD (36/607; 6%). The main limitation of our study was the inability to determine the actual incidence of kidney dysfunction in the health centers as it was not feasible to screen all the patients due to the high numbers seen daily. Conclusions This multicenter, non-randomized feasibility study in low-resource settings demonstrates that it is feasible to implement a comprehensive program utilizing POC testing and protocol-based management to improve the recognition and management of AKI and AKD in high-risk patients in primary care., Etienne Macedo and colleagues report on a point-of-care testing program for acute kidney injury and disease in high-risk primary care patients., Author summary Why was this study done? The study was designed to assess the feasibility of implementing interventions to optimize care of acute kidney injury (AKI). We used a comprehensive 5R approach—risk, recognition, response, renal support, and rehabilitation—to test the intervention in resource-constrained regions in Africa, Asia, and Latin America. What did the researchers do and find? Patients seen in community healthcare centers were screened and assigned a risk level for AKI based on their presenting signs and symptoms. Patients with moderate to high risk were approached for consent and enrolled in the study, underwent kidney function assessment, and were followed for their disposition and outcomes. Kidney function was assessed using point-of-care (POC) tests that included a test strip for measuring creatinine level in the blood using a portable device and a urine dipstick test to evaluate for proteinuria. What do these findings mean? The ISN 0by25 trial successfully demonstrated the utility of a symptom-based health assessment risk score coupled with a POC creatinine and urine dipstick test in early recognition of kidney disease and appropriate triaging and management of patients presenting to primary healthcare centers in low-income countries. Kidney dysfunction was associated with an increased risk of mortality, which was higher in patients with a moderate severity of AKI. Recognition and management of patients was facilitated by the combination of the POC test and guidance through teleconsultation.

© 2020 International Society of NephrologyThere is a huge gap between the number of patients worldwide requiring versus those actually receiving safe, sustainable, and equitable care for kidney failure. To address this, the International Society of Nephrology coordinated the development of a Strategic Plan for Integrated Care of Patients with Kidney Failure. Implementation of the plan will require engagement of the whole kidney community over the next 5–10 years.

This study was designed as a pilot study to see whether electronic patient-reported outcome measures using computer adaptive technology (CAT) could be successfully implemented in clinics caring for chronic kidney disease (CKD) and peritoneal dialysis (PD) patients. The results demonstrate the feasibility of using CAT on an iPad to assess the symptom burden and health-related quality of life of both PD and CKD patients.

Peritoneal dialysis in the United States is underutilized when compared to the experience in other developed countries. The reasons for this are multifactorial and include government regulatory issues, the priority of dialysis facilities, and education and training of nephrology trainees and patients. The challenges to expanding PD in the United States are discussed and strategies to overcome the barriers are outlined.

Kidney disease is a global public health concern across the age spectrum, including in children. However, our understanding of the true burden of kidney disease in low-resource areas is often hampered by a lack of disease awareness and access to diagnosis. Chronic kidney disease (CKD) in low-resource settings poses multiple challenges, including late diagnosis, the need for ongoing access to care and the frequent unavailability of costly therapies such as dialysis and transplantation. Moreover, children in such settings are at particular risk of acute kidney injury (AKI) owing to preventable and/or reversible causes - many children likely die from potentially reversible kidney disease because they lack access to appropriate care. Acute peritoneal dialysis (PD) is an important low-cost treatment option. Initiatives, such as the Saving Young Lives programme, to train local medical staff from low-resource areas to provide care for AKI, including acute PD, have already saved hundreds of children. Future priorities include capacity building for both educational purposes and to provide further resources for AKI management. As local knowledge and confidence increase, CKD management strategies should also develop. Increased awareness and advocacy at both the local government and international levels will be required to continue to improve the diagnosis and treatment of AKI and CKD in children worldwide.

Background and Aims Iron Deficiency (ID) is a common condition in NDD-CKD patients that is associated with poorer clinical outcomes. In different populations, such as congestive heart failure patients, treatment of ID leads to better clinical outcomes and HRQOL. However, the impact of ID on HRQOL is previously unknown among NDD-CKD individuals. We analyzed real world data from a multinational cohort of NDD-CKD stage 3 to 5 patients under nephrology care to evaluate the association between TSAT and HRQOL measures from the KDQOL-36. Method Patients from Brazil (N=205), France (N=2015), and the US (N=293) enrolled in the Chronic Kidney Disease Outcomes and Practice Patterns Study (CKDopps, 2013 to 2019) with available TSAT, ferritin, and HRQOL data were included in the analysis. We grouped patients according to their TSAT levels as ≤15%, >15-20%, >20-30% (reference group), >30-50%, and >50%. We considered the TSAT value that preceded the HRQOL measurement closest in time as the predictor. Linear mixed regression was used to estimate the mean differences (95% CI) in physical composite summary (PCS), mental composite summary (MCS), and KDQOL-36 subdomains across TSAT categories. Models were adjusted for potential confounders. Results 2513 patients (62% male, 44% with diabetes, mean (SD) age 67 (13) years; 48%, 44% and 8% having stage 3, 4 and 5 NDD-CKD, respectively) were included in the analysis. Mean TSAT was 25 % (10). Distribution across TSAT categories was 14%, 19%, 42%, 23, and 2%, respectively. The median [IQR] number of days between TSAT measurement and PRO collection was 24 [13, 49] days. Mean PCS was 41 (10) and MCS was 45 (11). In the multivariate analysis, TSAT ≤15% was associated with lower HRQOL scores, in particular PCS, and with less favorable effects and symptoms of kidney disease (Figure). Similarly, less favorable HRQOL scores captured in the SF-12 subdomains indicative of physical HRQOL were observed in patients with lower TSAT. The adjustment for Hb only slightly attenuated the effects, and the results were not different for subgroup of patients with hemoglobin Conclusion Lower TSAT levels, indicative of iron deficiency, are associated with poorer HRQOL in NDD-CKD patients, particularly for physical domains and effects of kidney disease, even after adjustment for potential confounders and stratification for normal and low hemoglobin levels. Randomized controlled trials of iron replacement therapy aiming to evaluate its impact on HRQOL among NDD-CKD individuals are needed to confirm and integrate these findings into clinical practice.

Substantial heterogeneity in practice patterns around the world has resulted in wide variations in the quality and type of dialysis care delivered. This is particularly so in countries without universal standards of care and governmental (or other organizational) oversight. Most high-income countries have developed such oversight based on documentation of adherence to standardized, evidence-based guidelines. Many low- and lower-middle-income countries have no or only limited organized oversight systems to ensure that care is safe and effective. The implementation and oversight of basic standards of care requires sufficient infrastructure and appropriate workforce and financial resources to support the basic levels of care and safety practices. It is important to understand how these standards then can be reasonably adapted and applied in low- and lower-middle-income countries. Keywords: hemodialysis; minimum safety standards; peritoneal dialysis; quality of care.

Current guidelines for the prescription of peritoneal dialysis dose rely on a single cut-off 'minimal' value ofA literature search was undertaken of studies comparing TBW estimation using two or three of the following methods: isotopic dilution (gold standard), anthropometric equations (e.g. Watson formula) and bioimpedance analysis. Studies of healthy and dialysis populations of all ages were included. Mean differences and 95% limits of agreement (LOA) were extracted and pooled.In 44 studies (31 including dialysis subjects), the between-method population means were typically within 1-1.5 L of each other, although larger bias was seen when applying anthropometric equations to different racial groups. However, the 95% LOA for all comparisons were consistently wide, typically ranging ±12-18% of the TBW. For a typical individual whose TBW is 35 L with a measuredThere are limitations to the accuracy of estimation of

Armed conflict jeopardizes patient care through shortages in vital medical supplies. When health care resources are both scarce and not secure, ethically justified principles of action are required to continue the treatment of patients. Although literature exists on the allocation and treatment decisions for military health care workers and warfighters, scarce literature exist for the use of available resources for civilians living within war zones. Chronic or acute kidney disease patients requiring replacement therapies are among the most vulnerable patient population in this regard. In this article, we discuss the use of peritoneal dialysis treatment for both acute and chronic kidney disease patients during war times.

Few studies have discussed the role of peritoneal dialysis (PD) in managing acute kidney injury (AKI) in critically ill patients. The present study compares the outcome of AKI in intensive care unit (ICU) patients randomized to treatment with tidal PD (TPD) or continuous venovenous hemodiafiltration (CVVHDF). One hundred and twenty-five ICU patients with AKI were randomly allotted to CVVHDF, (Group A, N = 62) or TPD, (group B, N = 63). Cause and severity of renal injury were assessed at the time of initiating dialysis. The primary outcome was hospital mortality at 28 days, and secondary outcomes were time to recovery of renal function, duration of stay in the ICU, metabolic and fluid control, and improvement of sensorial and hemodynamic parameters. No statistically significant differences were observed between groups in regard to patients' characteristics. The survival at 28 days was significantly better in the patients treated with TPD when compared to CVVHDF (69.8% vs. 46.8%, P < 0.01). Infectious complications were significantly less (P < 0.01) in the TPD group (9.5%) when compared to the CVVHDF group (17.7%). Recovery of kidney function (60.3% vs. 35.5%), median time to resolution of AKI and the median duration of ICU stay of 9 days (7-11) vs. 19 days (13-20) were all in favor of TPD (P < 0.01). This study suggests that there are better outcomes with TPD compared to CRRT in the treatment of critically ill patients with AKI.

Introduction Calcium oxalate supersaturation is regularly exceeded in the plasma of patients with end-stage renal disease (ESRD). Previous reports have indicated that hemodialfiltration (HDF) lowers elevated plasma oxalate (P Ox ) concentrations more effectively compared with hemodialysis (HD). We reevaluate the therapeutic strategy for optimized P Ox reduction with advanced dialysis equipment and provide data on the effect of extended treatment time on dialytic oxalate kinetics. Methods Fourteen patients with ESRD who underwent HDF 3 times a week for 4 to 4.5 hours (regular HDF; n = 8) or 7 to 7.5 hours (extended HDF; n = 6) were changed to HD for 2 weeks and then back to HDF for another 2 weeks. P Ox was measured at baseline, pre-, mid-, and postdialysis, and 2 hours after completion of the treatment session. Results Baseline P Ox for all patients averaged 28.0 ± 7.0 μmol/l. Intradialytic P Ox reduction was approximately 90% and was not significantly different between groups or treatment modes [F(1) = 0.63; P = 0.44]. Mean postdialysis P Ox concentrations were 3.3 ± 1.8 μmol/l. A rebound of 2.1 ± 1.9 μmol/l was observed within 2 hours after dialysis. After receiving 2 weeks of the respective treatment, predialysis P Ox concentrations on HD did not differ significantly from those on HDF [F(1) = 0.21; P = 0.66]. Extended treatment time did not provide any added benefit [F(1) = 0.76; P = 0.40]. Discussion In contrast to earlier observations, our data did not support a benefit of HDF over HD for P Ox reduction. With new technologies evolving, our results emphasized the need to carefully reevaluate and update traditional therapeutic regimens for optimized uremic toxin removal, including those used for oxalate.

Patient-reported outcome measures (PROMs) have been incorporated into the care of patients with ESRD for several years, primarily as research tools exploring the relationships between these measures and “hard” outcomes, such as mortality and hospitalizations ([1][1]–[3][2]). It has been

Objective Sleep and mood disorders are common in hemodialysis (HD) patients and the pathophysiology is still unclear. Tryptophan (TRP) and its metabolites may play a prominent role in neural pathways related to sleep, fatigue, and depression. Here, we sought to compare the levels of TRP and its metabolites between HD patients and healthy subjects and examine their association with sleep, fatigue, and depression in HD patients. The design was cross-sectional analysis. Subjects Ninety-nine adult patients on stable thrice weekly HD schedule between September 2011 and March 2014 and 10 healthy controls. Intervention Venous blood samples were drawn in healthy subjects and immediately before dialysis in chronic HD patients. TRP and kynurenine (KYN) metabolites were measured by high-performance liquid chromatography. The Medical Outcomes Study Sleep Scale, the PROMIS Short form Fatigue, and the Patient Health Questionnaire were administered concurrently. Main Outcome Measure Sleep, fatigue, and depression as assessed by subjective questionnaire. Results TRP levels were significantly lower (52.4 ± 15.2 vs. 67.9 ± 3.1 μmol/L; P P r 2 = 0.23 and 0.21; P ≤ .05, respectively). We found no association between TRP and KYN/TRP ratio with sleep disturbances, fatigue, and depression in HD patients. Conclusions Our study indicates disturbed TRP metabolism in HD patients, but low TRP levels were not related with sleep disturbances, depression, and fatigue. In contrast, KYN levels, a metabolite of TRP, were much higher in HD patients compared with controls, and higher KYN associated with depression and fatigue. Further studies exploring the biological and functional consequences of increased TRP catabolism in HD patients are warranted.

In December 2015, as part of the First African Dialysis Conference organized in Dakar, Senegal, 5 physicians from West African countries who have participated in the Saving Young Lives Program reviewed their experiences establishing peritoneal dialysis (PD) programs to treat patients with acute kidney injury (AKI). Thus far, nearly 200 patients have received PD treatment in these countries. The interaction and discussion amongst the participants at the meeting was meaningful and informative. The presentations highlighted the creativity, conviction, and determination of the physicians in overcoming the various barriers and challenges they encountered to establish PD/AKI programs. Hopefully, these successes and the increased awareness of the importance of early diagnosis and treatment of AKI will inspire much needed support from government, hospital, and international organizations.

As kidney disease progresses, patients often experience a variety of symptoms. A challenge for the nephrologist is to help determine if these symptoms are related to advancing CKD or the effect of various comorbidities and/or medications prescribed. The clinician also must decide the timing of dialysis initiation. The initiation of dialysis can have a variable effect on quality of life measures and the alleviation of uremic signs and symptoms, such as anorexia, fatigue, cognitive impairment, depressive symptoms, pruritus, and sleep disturbances. Thus, the initiation of dialysis should be a shared decision-making process among the patient, the family and the nephrology team; information should be provided, in an ongoing dialogue, to patients and their families concerning the benefits, risks, and effect of dialysis therapies on their lives.

A key component of treatment for all people with advanced kidney disease is supportive care, which aims to improve quality of life and can be provided alongside therapies intended to prolong life, such as dialysis. This article addresses the key considerations of supportive care as part of integrated end-stage kidney disease care, with particular attention paid to programs in low- and middle-income countries. Supportive care should be an integrated component of care for patients with advanced chronic kidney disease, patients receiving kidney replacement therapy (KRT), and patients receiving non-KRT conservative care. Five themes are identified: improving information on prognosis and support, developing context-specific evidence, establishing appropriate metrics for monitoring care, clearly communicating the role of supportive care, and integrating supportive care into existing health care infrastructures. This report explores some general aspects of these 5 domains, before exploring their consequences in 4 health care situations/settings: in people approaching end-stage kidney disease in high-income countries and in low- and middle-income countries, and in people discontinuing KRT in high-income countries and in low- and middle-income countries.

Fatigue is a highly prevalent and debilitating symptom in patients on hemodialysis therapy due to the uremic milieu, the hemodialysis treatment itself, and other comorbid conditions. However, fatigue remains underrecognized and the consequences are underappreciated because it may not be visible in clinical settings. This study aims to describe the experience that patients undergoing maintenance hemodialysis have with fatigue.Systematic review and thematic synthesis of qualitative studies.Patients undergoing hemodialysis.MEDLINE, Embase, PsycINFO, CINAHL, reference lists, and PhD dissertations were searched from inception to October 2018.All text from the results/conclusion of the primary studies.Thematic synthesis.65 studies involving 1,713 participants undergoing hemodialysis were included. We identified 4 themes related to fatigue: debilitating and exhausting burden of dialysis (bodily depletion, trapped in a vicious cycle of postdialysis exhaustion, vigilance and worry inhibiting rest, tiresome and agonizing regimen, and without remedy and relief), restricted life participation (deprived of time, managing energy reserves, frustrating need to rest, and joys foregone), diminishing capacities to fulfil relationship roles (losing ability to work and provide for family, failing as a parent, lacking stamina for sexual intimacy, and relying on others), and vulnerable to misunderstanding (being criticized for the need to rest and failing to meet expectations).Non-English articles were excluded and most studies were conducted in high-income countries.For patients undergoing hemodialysis who experience fatigue, fatigue is a profound and relentless exhaustion that pervades the entire body and encompasses weakness. The fatigue drains vitality in patients and constrains their ability to do usual activities and fulfill their roles and meet personal aspirations. Explicit recognition of the impact of fatigue and establishing additional effective interventions to improve fatigue are needed.

Objective The primary aim of this study was to evaluate the effect of increased frequency of dialysis (FHD) on change in fluid status and body composition using segmental bioimpedance. Approach Twelve stable HD patients were switched from 3 times/week to 6 times/week HD (FHD). Systolic blood pressure (SBP), body mass and body mass index (BMI) were measured pre- and post-HD. Calf resistance (R 5) at 5 kHz was measured using a multifrequency bioimpedance device (Hydra 4200). Calf resistivity (ρ = R 5 * area/length), normalized resistivity (CNR = ρ/BMI) and calf extracellular volume (cECV) were calculated. Fat mass was measured by Futrex body composition analyzers (Futrex 6100, Futrex Tech, Inc.). All measurements were performed at baseline (BL) and monthly for up to one year. Main results Nine patients completed one year of FHD. Compared to BL, body weight and cECV decreased, and CNR increased significantly by the first month but did not change thereafter. SBP pre-HD decreased significantly by the end of the first month with further reduction until month 12. Additionally, antihypertensive medication decreased significantly from baseline by month 4 and remained stable from month 6 throughout the rest of the study. The post-HD CNR in five of nine patients reached the range of normal (>18.5 10-2 * Ohm * m3 kg-1 for males and >19.1 10-2 * Ohm * m3 kg-1 for females) after 1 year FHD. In patients who returned to 3 times/week dialysis, CNR decreased significantly in the first week, and this was associated with increases in body weight and SBP. Significance Reduction of fluid overload with no alteration of body composition was observed in this study. Accordingly, improving fluid status was confirmed by reducing BP and use of antihypertensive drugs together with increase in CNR. Measurement of fluid status by CNR in hemodialysis patients is a new method to quantitatively assess hydration potentially creating a target for volume of fluid removal.

The global nephrology community recognizes the need for a cohesive strategy to address the growing problem of end-stage kidney disease (ESKD). In March 2018, the International Society of Nephrology hosted a summit on integrated ESKD care, including 92 individuals from around the globe with diverse expertise and professional backgrounds. The attendees were from 41 countries, including 16 participants from 11 low- and lower-middle–income countries. The purpose was to develop a strategic plan to improve worldwide access to integrated ESKD care, by identifying and prioritizing key activities across 8 themes: (i) estimates of ESKD burden and treatment coverage, (ii) advocacy, (iii) education and training/workforce, (iv) financing/funding models, (v) ethics, (vi) dialysis, (vii) transplantation, and (viii) conservative care. Action plans with prioritized lists of goals, activities, and key deliverables, and an overarching performance framework were developed for each theme. Examples of these key deliverables include improved data availability, integration of core registry measures and analysis to inform development of health care policy; a framework for advocacy; improved and continued stakeholder engagement; improved workforce training; equitable, efficient, and cost-effective funding models; greater understanding and greater application of ethical principles in practice and policy; definition and application of standards for safe and sustainable dialysis treatment and a set of measurable quality parameters; and integration of dialysis, transplantation, and comprehensive conservative care as ESKD treatment options within the context of overall health priorities. Intended users of the action plans include clinicians, patients and their families, scientists, industry partners, government decision makers, and advocacy organizations. Implementation of this integrated and comprehensive plan is intended to improve quality and access to care and thereby reduce serious health-related suffering of adults and children affected by ESKD worldwide.

The treatment of anemia with erythropoietic-stimulating agents is now part of the routine care of patients with CKD with guidelines for anemia management carefully outlined by Kidney Disease Improving Global Outcomes. The treatment of anemia impacts the health-related quality of life of CKD patients, primarily affecting the domains of energy/vitality and physical functioning. Improvements in these domains occur, in general, most noticeably when hemoglobin levels are raised from below 9 g/dL to the 10-12 range, with limited improvements occurring when hemoglobin levels are increased above 12 g/dL. Importantly, individual patient responses to anemia treatment vary depending on a variety of factors and it is important to assess the impact of treatment on each patient, particularly as nephrology care moves to a patient-centered care model.

Although multiple lines of evidence suggest a negative impact of secondary hyperparathyroidism on patients with kidney failure treated by hemodialysis, it is uncertain whether patients can detect associated symptoms. The objective was to determine whether changes in parathyroid hormone (PTH) levels are associated with changes in symptoms within this patient population.Prospective cohort.165 adults with hyperparathyroidism secondary to kidney failure diagnosed, a range of dialysis vintages, and receiving regular hemodialysis from a US single-provider organization.Change in PTH levels over 24 weeks.19 putative symptoms of secondary hyperparathyroidism measured up to 4 times using a self-administered questionnaire that assessed severity on a 5-level ordinal scale.Longitudinal associations between changes in PTH levels and symptom severity were assessed using generalized additive models.The 165 participants studied represented 81% of enrollees (N=204) who had sufficiently complete data for analysis. Mean age was 56 years and 54% were women. Increases in PTH levels over time were associated (P0.1) with worsening of bone aches and stiffness, joint aches, muscle soreness, overall pain, itchy skin, and tiredness, and the effects were more pronounced with larger changes in PTH levels.Findings may have been influenced by confounding by unmeasured comorbid conditions, concomitant medications, and multiple testing coupled with a P value threshold of 0.10.In this exploratory study, we observed that among patients with secondary hyperparathyroidism, increases in PTH levels over time were associated with worsening of 1 or more cluster of symptoms. Replication of these findings in other populations is needed before concluding about the magnitude and shape of these associations. If replicated, these findings could inform clinically useful approaches for measuring patient-reported outcomes related to secondary hyperparathyroidism.

Diminished health-related quality of life (HRQoL) is common in dialysis patients and associated with increased risks for morbidity and mortality. Patients may present limitations in both physical and mental HRQoL. Poor physical HRQoL may be defined by limited physical function, role limitations due to physical health, dissatisfaction with physical ability, and impaired mobility. Sleep disorders such as obstructive sleep apnea, restless legs, and fatigue are typical manifestations of poor physical HRQoL in dialysis patients. Poor mental HRQoL may be defined by depressive thinking, lack of positive affect, anxiety, and feelings of social isolation. The prevalence of depression is high in dialysis patients. Intensive hemodialysis (HD) can positively address HRQoL. In 3 randomized clinical trials, relative to conventional HD, intensive HD increased physical and mental component summary scores from the 36-Item Short-Form Health Survey (SF-36), although individual treatment effects of daily nocturnal HD were not statistically significant. In another large prospective study, initiation of short daily HD therapy was followed after 12 months by improvements in all SF-36 domains, sleep quality, and restless legs symptoms. In a small study of nocturnal HD, apnea and hypopnea episodes per hour decreased by almost 70% after conversion from conventional HD. Intensive HD is also associated with a large reduction in postdialysis recovery time. In contrast, 2 randomized clinical trials failed to demonstrate statistically significant effects of intensive HD on the Beck Depression Inventory score despite a significant decrease in Beck Depression Inventory score in the prospective study of short daily HD. Furthermore, intensive HD may not improve objective physical performance and can increase burden on caregivers in the home setting. In conclusion, intensive HD potentially can address both physical and mental aspects of poor HRQoL relative to conventional HD. However, more studies are needed to understand the effects of intensive HD, including specific schedules, on HRQoL.

Epidemiological data for acute kidney injury are scarce, especially in low-income countries (LICs) and lower-middle-income countries (LMICs). We aimed to assess regional differences in acute kidney injury recognition, management, and outcomes.In this multinational cross-sectional study, 322 physicians from 289 centres in 72 countries collected prospective data for paediatric and adult patients with confirmed acute kidney injury in hospital and non-hospital settings who met criteria for acute kidney injury. Signs and symptoms at presentation, comorbidities, risk factors for acute kidney injury, and process-of-care data were obtained at the start of acute kidney injury, and need for dialysis, renal recovery, and mortality recorded at 7 days, and at hospital discharge or death, whichever came earlier. We classified countries into high-income countries (HICs), upper-middle-income countries (UMICs), and combined LICs and LMICs (LLMICs) according to their 2014 gross national income per person.Between Sept 29 and Dec 7, 2014, data were collected from 4018 patients. 2337 (58%) patients developed community-acquired acute kidney injury, with 889 (80%) of 1118 patients in LLMICs, 815 (51%) of 1594 in UMICs, and 663 (51%) of 1241 in HICs (for HICs vs UMICs p=0.33; p0.0001 for all other comparisons). Hypotension (1615 [40%] patients) and dehydration (1536 [38%] patients) were the most common causes of acute kidney injury. Dehydration was the most frequent cause of acute kidney injury in LLMICs (526 [46%] of 1153 vs 518 [32%] of 1605 in UMICs vs 492 [39%] of 1260 in HICs) and hypotension in HICs (564 [45%] of 1260 vs 611 [38%%] of 1605 in UMICs vs 440 [38%] of 1153 LLMICs). Mortality at 7 days was 423 (11%) of 3855, and was higher in LLMICs (129 [12%] of 1076) than in HICs (125 [10%] of 1230) and UMICs (169 [11%] of 1549).We identified common aetiological factors across all countries, which might be amenable to a standardised approach for early recognition and treatment of acute kidney injury. Study limitations include a small number of patients from outpatient settings and LICs, potentially under-representing the true burden of acute kidney injury in these areas. Additional strategies are needed to raise awareness of acute kidney injury in community health-care settings, especially in LICs.International Society of Nephrology.

Many patients who receive maintenance hemodialysis experience poor sleep. Uncontrolled studies suggest frequent hemodialysis improves sleep quality, which is a strong motivation for some patients to undertake the treatment. We studied the effects of frequent in-center ('daily') and nocturnal home hemodialysis on self-reported sleep quality in two randomized trials.Participants were randomly assigned to frequent (six times per week) or conventional (three times per week) hemodialysis in the Frequent Hemodialysis Network Daily (n = 245) and Nocturnal (n = 87) Trials. We used the Medical Outcomes Study Sleep Problems Index II (SPI II), a validated and reliable instrument in patients with end-stage renal disease, to measure self-reported sleep quality. The SPI II is scored from 0-100, with a higher value indicating poorer quality of sleep. A mean relative decline in SPI II would suggest improved sleep quality. The primary sleep outcome was the change in the SPI II score over 12 months.In the Daily Trial, after adjustment for baseline SPI II, subjects randomized to frequent as compared with conventional in-center hemodialysis experienced a 4.2 [95% confidence interval (CI) 0.4-8.0] point adjusted mean relative decline in SPI II at 4 months and a 2.6 (95% CI -2.3-7.5) point adjusted mean relative decline at 12 months. In the Nocturnal Trial, subjects randomized to frequent nocturnal as compared with conventional home hemodialysis experienced 2.9 (95% CI -3.4-9.3) and 4.5 (95% CI -3.2-12.2) point mean relative declines at Months 4 and 12, respectively.Although a possible benefit of frequent in-center hemodialysis was observed at 4 months, neither frequent in-center hemodialysis nor home nocturnal hemodialysis demonstrated significant improvements in self-reported sleep quality compared with conventional hemodialysis at 12 months.

Background Little is known about the prevalence of functional impairment in peritoneal dialysis (PD) patients, its variation by country, and its association with mortality or transfer to hemodialysis. Methods A prospective cohort study was conducted in PD patients from 7 countries in the Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) (2014 – 2017). Functional status (FS) was assessed by combining self-reports of 8 instrumental and 5 basic activities of daily living, using the Lawton-Brody and the Katz questionnaires. Summary FS scores, ranging from 1.25 (most dependent) to 13 (independent), were based on the patient's ability to perform each activity with or without assistance. Logistic regression was used to estimate the odds ratio (OR; 95% confidence interval [CI]) of a FS score < 11 comparing each country with the United States (US). Cox regression was used to estimate the hazard ratio (HR; 95% CI) for the effect of a low FS score on mortality and transfer to hemodialysis, adjusting for case mix. Results Of 2,593 patients with complete data on FS, 48% were fully independent (FS = 13), 32% had a FS score 11 to < 13, 14% had a FS score 8 to < 11, and 6% had a FS score < 8. Relative to the US, low FS scores (< 11; more dependent) were more frequent in Thailand (OR = 10.48, 5.90 – 18.60) and the United Kingdom (UK) (OR = 3.29, 1.77 – 6.08), but similar in other PDOPPS countries. The FS score was inversely and monotonically associated with mortality but not with transfer to hemodialysis; the HR, comparing a FS score < 8 vs 13, was 4.01 (2.44 – 6.61) for mortality and 0.91 (0.58 – 1.43) for transfer to hemodialysis. Conclusion Regional differences in FS scores observed across PDOPPS countries may have been partly due to differences in regional patient selection for PD. Functional impairment was associated with mortality but not with permanent transfer to hemodialysis.

HIV-positive individuals are at increased risk for kidney disease, including HIV-associated nephropathy, non-collapsing focal segmental glomerulosclerosis, immune-complex kidney disease, and comorbid kidney disease, as well as kidney injury resulting from prolonged exposure to antiretroviral therapy or from opportunistic infections. Clinical guidelines for kidney disease prevention and treatment in HIV-positive individuals are largely extrapolated from studies in the general population, and do not fully incorporate existing knowledge of the unique HIV-related pathways and genetic factors that contribute to the risk of kidney disease in this population. We convened an international panel of experts in nephrology, renal pathology, and infectious diseases to define the pathology of kidney disease in the setting of HIV infection; describe the role of genetics in the natural history, diagnosis, and treatment of kidney disease in HIV-positive individuals; characterize the renal risk-benefit of antiretroviral therapy for HIV treatment and prevention; and define best practices for the prevention and management of kidney disease in HIV-positive individuals.

Introduction There is interest in developing alternative therapies to loop diuretics for decongestion heart failure (HF). One approach is peritoneal dialysis (PD). However, PD requires large intraperitoneal volumes and delivers limited sodium removal due to the high concentration of sodium in standard PD solutions. Previously, we have demonstrated in normal and HF animal models that Direct Sodium Removal (DSR) with a sodium-free peritoneal solution is highly effective in removing large quantities of sodium and water, with low volumes of DSR solution. Hypothesis DSR will be safe, well tolerated, and result in substantially greater sodium removal than standard PD solution. Methods 10 patients underwent randomization and crossover to DSR solution (sodium free 10% dextrose) or standard PD solution (Dianeal 4.25% dextrose, Baxter), each separated by 1 week. One liter of either DSR solution or standard PD solution was infused into the peritoneum and left to dwell for 2 hours, with crossover to the alternate solution one week later. Vital signs, blood, and peritoneal fluid were obtained serially throughout the protocol. The primary endpoint was safety/tolerability defined as completion of the 2-hour dwell without significant discomfort or AE. The secondary efficacy endpoint was the difference in sodium removal between DSR solution and standard PD solution (NCT03801226; IND141103). Results DSR solution was well-tolerated and did not cause significant discomfort or adverse events. Individual safety parameters such as change in blood pressure, plasma potassium, bicarbonate, calcium and magnesium were similar between solutions (p>0.35 for all). There was a borderline significant 1 mmol/L decrease in serum sodium from baseline to 2 hours in the DSR group (p=0.05) but this resolved by 60 minutes after draining the solution (p=0.34). Plasma glucose increased with both DSR and standard PD solution (p Conclusion DSR was safe and well-tolerated in human subjects. Sodium removal with DSR is substantial and dramatically greater than what is achievable with standard PD solutions. Additional research evaluating the use of DSR as a method to prevent and treat hypervolemia in HF is warranted.
