Abstract Bioimpedance spectroscopy (BIS) has proven to be a promising non-invasive technique for fluid monitoring in haemodialysis (HD) patients. While current BIS-based monitoring of pre- and post-dialysis fluid status utilizes benchtop devices, designed for intramural use, advancements in micro-electronics have enabled the development of wearable bioimpedance systems. Wearable systems meanwhile can offer a similar frequency range for current injection as commercially available benchtop devices. This opens opportunities for unobtrusive longitudinal fluid status monitoring, including transcellular fluid shifts, with the ultimate goal of improving fluid management, thereby lowering mortality and improving quality of life for HD patients. Ultra-miniaturized wearable devices can also offer simultaneous acquisition of multiple other parameters, including haemodynamic parameters. Combination of wearable BIS and additional longitudinal multiparametric data may aid in the prevention of both haemodynamic instability as well as fluid overload. The opportunity to also acquire data during interdialytic periods using wearable devices likely will give novel pathophysiological insights and the development of smart (predicting) algorithms could contribute to personalizing dialysis schemes and ultimately to autonomous (nocturnal) home dialysis. This review provides an overview of current research regarding wearable bioimpedance, with special attention to applications in end-stage kidney disease patients. Furthermore, we present an outlook on the future use of wearable bioimpedance within dialysis practice.

Abstract Background Informed dialysis selection and greater home dialysis use are the two long-desired, underachieved targets of advanced chronic kidney disease care in the US healthcare system. Observational institutional studies have shown that comprehensive pre-end stage kidney disease (ESKD) disease education (CPE) can improve both these outcomes. However, lack of validated protocols, well-controlled studies, and systemic models have limited wide-spread adoption of CPE in the US. We hypothesized that a universal CPE and patient-centered initiation of renal replacement therapy can improve multiple clinical, patient-centered and health service outcomes in advanced chronic kidney disease (CKD) and ESKD.Methods Trial to Evaluate and Assess the effects of CPE on Home dialysis in Veterans (TEACH-VET) is a mixed method randomized controlled trial aimed to evaluate the effects of a system-based approach for providing CPE to all Veterans with advanced CKD across a regional healthcare System. The study will randomize 544 Veterans with non-dialysis stage 4 and 5 CKD in a 1:1 allocation stratified by their annual family income and the stage of CKD to an intervention (CPE) arm or control arm. Intervention arm will receive a two-phase CPE in an intent-to-teach manner. Control arm will receive usual clinical care supplemented by resources for the freely-available kidney disease information. Participants will be followed after intervention/control for the duration of the study or until 90-days post-ESKD, whichever occurs earlier.Results The primary outcome will assess the proportion of Veterans using home dialysis at 90-days post-ESKD, and secondary outcomes will include post-intervention/control CKD knowledge, confidence in dialysis decision and home dialysis selection. Qualitative arm of the study will use semi-structured interviews to in-depth assess Veterans’ satisfaction with the intervention, preference for delivery, and barriers and facilitators to home dialysis selection and use. Several post-ESKD clinical, patient-centered and health services outcomes will be assessed 90-days post-ESKD as additional secondary outcomes.Conclusion The results will provide evidence regarding the need and efficacy of a system-based, patient-centered approach towards universal CPE for all patients with advanced CKD. If successful, this may provide a blueprint for developing such programs across the similar healthcare infrastructures throughout the country.Trial registration: NCT04064086

AbstractThe health crisis induced by the pandemic of coronavirus 2019 disease (COVID-19) has had a major impact on dialysis patients in France. The incidence of infection with acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the first wave of the COVID-19 epidemic was 3.3% among dialysis patients—13 times higher than in the general population. The corresponding mortality rate was high, reaching 21%. As of 19th April, 2021, the cumulative prevalence of SARS-CoV-2 infection in French dialysis patients was 14%. Convergent scientific data from France, Italy, the United Kingdom and Canada show that home dialysis reduces the risk of SARS-CoV-2 infection by a factor of at least two. Unfortunately, home dialysis in France is not sufficiently developed: the proportion of dialysis patients being treated at home is only 7%. The obstacles to the provision of home care for patients with end-stage kidney disease in France include (i) an unfavourable pricing policy for home haemodialysis and nurse visits for assisted peritoneal dialysis (PD), (ii) insufficient training in home dialysis for nephrologists, (iii) the small number of administrative authorizations for home dialysis programs, and (iv) a lack of structured, objective information on renal replacement therapies for patients with advanced chronic kidney disease (CKD). We propose a number of pragmatic initiatives that could be simultaneously enacted to improve the situation in three areas: (i) the provision of objective information on renal replacement therapies for patients with advanced CKD, (ii) wider authorization of home dialysis networks and (iii) price increases in favour of home dialysis procedures.

Hemodialysis (HD) is a necessary treatment for end-stage kidney disease (ESKD) patients in order to prevent cardiovascular morbidity and mortality that may be related to the hemodynamic effects of rapid ultrafiltration. Despite significant advances in HD technology, only half of ESKD patients treated with HD survive more than 3 years. Fluid management remains one of the most challenging aspects of HD care, with serious implications for morbidity and mortality. In this paper, we develop a novel algorithm to design real time optimal, robust ultrafiltration rates based on actual HD data to identifying the parameters of a fluid volume model of an individual patient during HD. Our design achieves, if exists, an optimal ultrafiltration profile for the identified nominal model under maximum ultrafiltration and hematocrit constraints and guarantees that these constraints are satisfied over a pre-defined set of parameter uncertainty. We demonstrate the robust performance of our algorithm through a combination of clinical data and simulations.

Abstract Chronic kidney disease (CKD), especially end-stage kidney disease (ESKD), is associated with increased risk for cardiovascular events and all-cause mortality. Exercise intolerance as well as reduced cardiovascular reserve are extremely common in patients with CKD. Cardiopulmonary exercise testing (CPET) is a non-invasive, dynamic technique that provides an integrative evaluation of cardiovascular, pulmonary, neuropsychological and metabolic function during maximal or submaximal exercise, allowing the evaluation of functional reserves of these systems. This assessment is based on the principle that system failure typically occurs when the system is under stress and, thus, CPET is currently considered to be the gold-standard for identifying exercise limitation and differentiating its causes. It has been widely used in several medical fields for risk stratification, clinical evaluation and other applications but its use in everyday practice for CKD patients is scarce. This article describes the basic principles and methodology of CPET and provides an overview of important studies that utilized CPET in patients with ESKD, in an effort to increase awareness of CPET capabilities among practicing nephrologists.
