Hemodialysis

This planned randomized controlled trial will enroll 164 patients undergoing hemodialysis to compare the effectiveness of leg massage versus vibration therapy on muscle cramps and patient comfort. Participants will be randomly assigned to one of three groups: a massage group receiving 20-minute lower extremity massage sessions, a vibration group receiving 10-minute vibration therapy, or a control group receiving standard care only. All interventions will be administered three times per week for two weeks (six sessions). The study will evaluate cramp frequency, cramp severity using a Visual Analog Scale, sleep quality through the Pittsburgh Sleep Quality Index, and patient comfort scores. Both interventions are expected to significantly reduce cramp frequency and severity compared to standard care, with massage anticipated to show superior benefits for sleep quality and home-based cramp reduction, while vibration is expected to provide better immediate comfort during dialysis sessions. No serious adverse events are predicted. The findings will help healthcare providers offer personalized, evidence-based non-pharmacological options to improve quality of life for hemodialysis patients.

People with end-stage kidney disease who receive hemodialysis are often told to strictly limit foods high in potassium, such as fruits, vegetables, legumes, nuts, and whole grains. This advice is intended to prevent high blood potassium levels (hyperkalemia), which can cause dangerous heart rhythm problems. However, these restrictions can make eating difficult, reduce diet quality, and lower quality of life. New research suggests that not all sources of potassium affect the body in the same way. Potassium added to highly processed foods is more easily absorbed than potassium naturally found in whole foods like fruits and vegetables. Large studies have found little evidence that eating potassium-rich whole foods increases blood potassium levels in people on dialysis. Clinical guidelines are beginning to shift, but no high-quality clinical trial has tested whether a more flexible, food-based approach is safe for people receiving hemodialysis. This study will compare two dietary approaches in 148 adults on hemodialysis: the usual low potassium diet and a "liberalized" potassium diet that encourages minimally processed foods while limiting highly processed foods with potassium additives. Participants will receive dietitian support and grocery assistance for 12 weeks. The investigators will closely monitor blood potassium levels to ensure safety. The investigators will also examine whether the liberalized diet is as safe as standard care, and whether it improves diet quality and quality of life. The investigators will also study factors that influence the participant's ability to follow the diet in real-world settings. If safe, this approach could reduce unnecessary food restrictions, improve diet quality, and enhance quality of life for people receiving hemodialysis, while maintaining patient safety.

Hemodialysis patients may experience dialysis-related distress due to long-term treatment requirements, dietary and fluid restrictions, medication use, vascular access problems, dialysis-related symptoms, and psychosocial challenges. Nurse-led self-management programs may help patients improve dialysis self-management, reduce distress, and support treatment adherence. This study aims to evaluate the effect of a nurse-led needs-based dialysis self-management program on dialysis-related distress in patients receiving hemodialysis. The study will be conducted as a single-center, two-arm, parallel-group, randomized controlled trial. A total of 100 adult hemodialysis patients will be randomly assigned to either the intervention group or the control group in a 1:1 ratio. Participants in the intervention group will receive a 6-week nurse-led needs-based dialysis self-management program in addition to routine hemodialysis care. Participants in the control group will continue routine hemodialysis care. Data will be collected at baseline, 6 weeks, and 18 weeks. The primary outcome is dialysis-related distress. Secondary outcomes include illness and treatment uncertainty, treatment adherence, and clinical adherence indicators.

The aim of our study is to evaluate the impact of repeated episodes of ischemic quenching on changes in blood pressure, heart rate and laboratory parameters of inflammation in patients with kidney diseases. There is credible evidence that intentionally producing periods of ischemia provides protection of the myocardium and blood vessels against subsequent ischemic injury. The examination will be performed during hospitalization in the Department of Nephrology, Hypertension, Transplantology and Internal Diseases and will last 4 days. On the first day, blood pressure will be measured using an automatic blood pressure monitor, radial artery pulse, blood saturation will be measured using a pulse oximeter, and approximately 6 ml of venous blood will be collected from the elbow bend area for laboratory tests. Then, compression of the lower limb below the knee will be performed using a blood pressure cuff. Four 5-minute cycles of inflation and deflation of the cuff will be performed. The pressure on the lower limb will be repeated on the next two days. On the last day of the examination, blood pressure, heart rate and blood saturation will be measured again, and approximately 6 ml of venous blood will be collected again for laboratory tests.

This expected prospective randomized control trial study will involve 60 haemodialysis patients with neck pain. The patients in the experimental group (E) will subject, medical treatment besides acupuncture laser therapy. Medical treatment will be used in the control group (C). Pain and quality of life assessment will be used in the assessment of outcome.

Many people who have kidney failure require hemodialysis treatments to stay alive. Hemodialysis is a procedure that cleans the blood of the toxins and fluids that build up when kidneys don't work. Most patients receive hemodialysis treatment three times every week and each treatment lasts 4 hours. These patients spend 156 days per year receiving hemodialysis treatments. This is a very large time burden which has a tremendous impact on well-being and life satisfaction. Current usual approach of prescribing three hemodialysis treatments per week is not based on good studies and assumes that all people need the same number of hemodialysis treatments per week regardless of their age, values, life expectancy or other health conditions. Over time, increasingly more elderly people are needing to start hemodialysis treatments. The investigators have conducted a preliminary study that shows that patients who are 70 years of age or older can do well when only receiving only two hemodialysis treatments per week. In this preliminary study, receiving two hemodialysis treatments per week was no different than three hemodialysis treatments per week with regards to important safety measures including blood values and management of body fluid levels. The investigators now propose to carry out a much larger study in many centers across Canada that will compare two times per week hemodialysis treatments to three times per week hemodialysis treatments in elderly patients who have reached kidney failure and are beginning their hemodialysis journey. The investigators want to know if receiving hemodialysis treatments twice per week increases the number of days that a patient is able to spend at home without increasing rates of hospitalization or death compared to receiving hemodialysis treatments three times per week. The investigators also want to know if this is better for people's quality of life, safe, less expensive for the health care system and friendlier to the environment. The results of this study will help elderly patients needing to start hemodialysis treatments, medical care teams who help make decisions about how many hemodialysis treatments per week are necessary as well as kidney organizations that oversee kidney care for patients in Canada and around the world.

This study aims to compare the effects of medium cut-off (MCO) and high-flux hemodialysis membranes on mineral and bone metabolism biomarkers in patients receiving maintenance hemodialysis. Chronic kidney disease-mineral and bone disorder (CKD-MBD) is characterized by disturbances in biomarkers such as fibroblast growth factor-23 (FGF-23) and sclerostin, which are associated with bone turnover, vascular calcification, and adverse clinical outcomes. This is a single-center, prospective, randomized, open-label, two-sequence, two-period crossover clinical study. Thirty adult patients receiving maintenance hemodialysis will be randomized to receive either MCO membrane treatment followed by high-flux membrane treatment or the reverse sequence, with each treatment period lasting three months. Serum FGF-23 and sclerostin levels will be measured at baseline, Month 3, and Month 6. Additional assessments will include pulse wave velocity (PWV), body composition monitoring (BCM), handgrip strength, health-related quality of life (KDQOL-36), pruritus severity (UP-Dial), and pain assessment (SF-MPQ). The study will evaluate whether MCO membranes provide additional benefits compared with conventional high-flux membranes regarding CKD-MBD-related biomarkers and patient-centered outcomes.

This observational study will compare cardiovascular status, bone mineral metabolism, systemic inflammation, body composition, functional status, quality of life, pruritus, and pain among patients receiving different renal replacement therapy modalities and healthy controls. Adult participants will be included in four groups: maintenance hemodialysis, continuous ambulatory peritoneal dialysis, automated peritoneal dialysis, and healthy controls. No new treatment, drug, dialysis modality, or experimental device will be assigned as part of the study. Participants will continue their routine clinical care. Serum interleukin-6 (IL-6), vascular cell adhesion molecule-1 (VCAM-1), fibroblast growth factor-23 (FGF-23), and sclerostin levels will be measured. Arterial stiffness will be assessed using pulse wave velocity (PWV), and body composition will be assessed using the Body Composition Monitor (BCM). Handgrip strength, quality of life, pruritus, and pain scores will also be evaluated. The study will also explore correlations between biochemical biomarkers, arterial stiffness, body composition, and patient-reported outcomes. In the automated peritoneal dialysis group, objective treatment adherence will additionally be assessed using the Sharesource (Baxter/Vantive) cloud-based remote patient monitoring platform.

Patients receiving maintenance hemodialysis are at increased risk of cardiovascular disease, chronic inflammation, endothelial dysfunction, and impaired quality of life. Medium cut-Off (MCO) hemodialysis membranes have been developed to enhance the removal of middle-molecular-weight uremic toxins compared with conventional high-flux membranes, which may improve inflammatory status and cardiovascular health. The aim of this study is to compare the effects of MCO and high-flux hemodialysis membranes on inflammatory biomarkers and cardiovascular function in adult patients receiving maintenance hemodialysis. The primary outcomes are changes in serum interleukin-6 (IL-6) and vascular cell adhesion molecule-1 (VCAM-1) levels. Secondary outcomes include arterial stiffness assessed by pulse wave velocity (PWV), body composition assessed by Body Composition Monitor (BCM), handgrip strength, and patient-reported outcomes including quality of life, pruritus, and pain scores. This is a prospective, randomized, open-label, two-sequence, two-period crossover study conducted at Gazi University Faculty of Medicine. Thirty adult hemodialysis patients will be randomized to one of two treatment sequences. Participants in Sequence A will receive MCO dialysis membranes for the first 3 months followed by high-flux membranes for the next 3 months. Participants in Sequence B will receive high-flux membranes for the first 3 months followed by MCO membranes for the next 3 months. Blood samples and clinical assessments will be performed at baseline, month 3, and month 6. The study is expected to provide evidence regarding the effects of different dialysis membrane technologies on inflammation and cardiovascular health and may contribute to optimizing membrane selection in routine hemodialysis practice.

Pulmonary hypertension (PH) is a frequent and clinically significant complication in patients with end-stage kidney disease (ESKD) undergoing maintenance hemodialysis (HD). However, PH assessment in this population is often confounded by volume overload, leading to potential overestimation and misclassification. This prospective, multicenter observational study aims to evaluate the prevalence, phenotype, and predictors of PH in HD patients under standardized euvolemic conditions. A structured pretrial phase including volume assessment and correction will be performed prior to echocardiographic evaluation, which will be conducted after confirmation of euvolemia, post-hemodialysis or on the following day. In participants with echocardiographic findings suggestive of PH, right heart catheterization may be performed when clinically indicated and after obtaining specific informed consent. The study integrates clinical, biological, dialysis-related, and echocardiographic data to provide a comprehensive characterization of PH in a well-defined ESKD population.

The goal of this clinical trial is to evaluate the feasibility of two different preoperative hemodialysis schedules for people with end-stage kidney disease (ESKD) who undergo surgical procedures. The main questions it aims to answer are: Is it feasible to randomize participants with ESKD undergoing nonemergent surgical procedures to same-day hemodialysis versus no same-day hemodialysis? Is it safe to randomize participants with ESKD undergoing nonemergent surgical procedures to same-day hemodialysis versus no same-day hemodialysis? Researchers will compare the two hemodialysis schedules to see if the scheduling and safety profiles are the same. Participants will: Answer questions about their health up to 4 weeks before and 4 weeks after the surgical procedure. Receive hemodialysis on the day of the surgical procedure or not, depending on the study treatment assignment.

This randomised controlled study aims to evaluate the effects of mindfulness meditation on sleep quality, perceived stress and symptoms levels ion hemodialysis patients. Participants in the intervention group will receive a 4 week mindfulness meditation program in addition to routine care. Outcomes will be assessed before and after the intervention using validated measurement tools.

Chronic kidney disease (CKD) patients undergoing maintenance hemodialysis experience profound alterations in their gut microbiota, leading to dysbiosis and increased gut permeability. This disruption facilitates the translocation of endotoxins and gut-derived uremic toxins such as indoxyl sulfate and p-cresyl sulfate into the systemic circulation, contributing to heightened systemic inflammation, cardiovascular disease risk, and accelerated CKD progression. Synbiotic supplementation, particularly multispecies formulations, has emerged as a promising therapeutic strategy to restore gut microbial balance, enhance intestinal barrier integrity, and reduce the systemic burden of deleterious microbial metabolites. These probiotics potentially improve clinical outcomes by modulating inflammatory pathways and decreasing circulating levels of uremic toxins. Despite these insights, few clinical trials have comprehensively assessed the effects of multispecies synbiotic on fecal microbiome composition, gut permeability and uremic toxin profiles in hemodialysis patients. This pilot study aims to fill this gap by evaluating the modulatory effects of a 12-week multispecies synbiotic intervention.

The objective of this study is to evaluate the effects of royal jelly on inflammation and cellular senescence in patients with chronic kidney disease (CKD) on hemodialysis (HD).

Kidney failure is common. In some people the ability of the kidneys to clean poisons out of the blood gets so low they need to be hooked up to a machine three times a week to do it for them. This is called dialysis. Unfortunately, although this treatment removes those waste products, people who need dialysis die much more often than people who don't need dialysis. Dialysis causes extreme stress on the body and leads to many organs being damaged. Removing fluid from the body quickly causes the equivalent of repeated little heart attacks or little strokes in the brain. Many patients struggle to tolerate having all the fluid that they have drunk since their last dialysis session removed- without unpleasant symptoms of dangerously low blood pressure (which makes the damage worse). Dialysis treatments can be done more slowly or more often, but that means having to spend a lot more time at the hospital and is difficult for the health system to be able to provide the extra treatment time. Could extra fluid be removed in between dialysis sessions? Up to now there has not been a way to effectively do this. Investigators have now designed and built an entirely new, very small and very simplified, device that can do part of what a dialysis machine does. It doesn't clean the blood or replace the need for conventional dialysis sessions, but it can provide additional and gentle removal of fluid which wasn't able to be taken off during a standard treatment session. If this study is successful, it will be the first time that a wearable device has been successfully built and used to take off extra fluid when dialysis patients are not in the hospital. The ability to do this opens up the possibility of, 1) helping to treat patients (both making people feel better and live longer) who can't tolerate getting off all the fluid in the short 3-4 hours they are on the dialysis machine in the hospital, and 2) helping patients who feel OK having the fluid taken off but are silently being subjected to damage to their organs due to the rapid removal, have reduced damage.

Background and problem Chronic kidney disease (CKD) affects a large share of adults worldwide and is a growing public-health concern. People with advanced CKD can develop "uremia", a dangerous build-up of waste products in the blood that the failing kidneys cannot remove. Even when patients receive regular dialysis, many so-called "uremic toxins" remain in the body because some of these substances bind tightly to blood proteins and are poorly removed by dialysis. Over 100 uremic toxins have been identified and classified and protein-bound toxins such as Indoxylsulfate and p-Cresylsulfate are especially difficult to clear by dialysis. Some uremic toxins are linked to heart and blood-vessel disease, inflammation, and worse outcomes in dialysis patients. For example, Indoxylsulfate has been associated with higher mortality, vascular calcification, vessel stiffness and heart failure. Reducing these toxins might therefore improve quality of life and lower cardiovascular risk in people on dialysis. Purpose of the study The study will test whether adding inner, fermentable pea fiber (a natural prebiotic) to the daily diet of hemodialysis patients can lower blood levels of uremic toxins-especially Indoxylsulfate-and improve related markers of inflammation and cardiovascular risk. The investigators hypothesize that fermentable fibers change gut bacterial composition so that less toxin-forming bacterial metabolism (from amino acids like tryptophan) occurs, thereby reducing the amount of harmful metabolites that reach the blood. Type of study: Randomized, double-blind, controlled trial with two groups. Duration: 8 weeks of intervention. Intervention: Participants will receive daily baked goods (bread, rolls, muffins, scones, pizza bread) that together provide 20 g of pea fiber per day; the control group will receive identical foods without added pea fiber. The fiber mix uses commercially available inner pea-fiber products. Blood and stool sampling: Blood samples are taken before the intervention, at 4 weeks and at 8 weeks to measure Indoxylsulfate and other toxins, inflammation markers, vitamin D metabolites and cardiovascular risk markers. A subgroup will also provide stool samples to study changes in the gut microbiome. Who can join Adults aged 18-89 who have been on chronic hemodialysis for at least three months and receive dialysis two to three times per week are eligible. The study excludes people with recent serious infections, advanced liver disease, active cancer, recent blood transfusion, pregnancy, certain food intolerances or inability to consent. Each study arm will include 36 participants. Primary and secondary outcomes Primary outcome: Change in blood Indoxylsulfate concentration between the pea-fiber group and the control group. Secondary outcomes: Levels of other uremic toxins, routine kidney-related blood tests (creatinine, urea, uric acid), electrolytes, vitamin D metabolites, inflammatory markers, lipid markers, FGF23, short-chain fatty acids, sKlotho, and the effect of patient serum on cytokine production in a standard immune cell line. Stool analyses in a subgroup will examine shifts in bacterial groups and metabolic networks. How the intervention is delivered and monitored Foods are prepared in a certified bakery and coded so neither participants nor study staff know who receives pea fiber or placebo. To improve adherence, participants choose from a variety of pre-portioned baked items and are advised to spread intake across the day. Unused portions are returned and logged. Dietary recalls and symptom questionnaires are collected to monitor changes in overall diet, appetite and gastrointestinal side effects. Blood draws are timed before dialysis after the long interdialytic interval to standardize measurements. Potential impact and limitations If fermentable inner pea fibers lower Indoxylsulfate and related toxins, this would support a simple, food-based strategy to reduce toxin burden and possibly cardiovascular risk in dialysis patients. However, previous studies show mixed results depending on the type of fiber used: fermentable fibers (like amylose-rich starch or inulin) have produced beneficial changes in some trials, while non-fermentable fibers did not. Since evidence high-quality randomized trials in dialysis patients is still limited there is the need for this study.

Cognitive decline is increasingly recognized among patients receiving maintenance hemodialysis (HD). This can include trouble remembering, slower thinking or mentally feeling foggy. This research is being done to determine if a new medication (AV-001) can protect the brain from injury caused by hemodialysis by strengthening blood vessels in the brain and reducing inflammation. If successful, this research could lead to better protection for the brains of people undergoing regular dialysis, potentially reducing the risk of cognitive decline and stroke.

This study aims to evaluate the effects of progressive muscle relaxation exercises on depression and fatigue levels in patients undergoing hemodialysis treatment. Progressive muscle relaxation is applied as an individualized non-pharmacological intervention, and its potential contribution to psychological well-being is investigated. The study seeks to determine whether regular relaxation exercises can reduce depressive symptoms, alleviate fatigue, and improve overall emotional well-being in hemodialysis patients. Findings from this research are expected to provide evidence for the use of relaxation-based interventions as supportive care methods in the management of psychological symptoms associated with chronic kidney disease and hemodialysis.

People with advanced kidney disease need dialysis to remove waste products from the blood. Some of these waste products, called uremic toxins, are small, while others are medium-sized and more difficult to remove. Poor removal of these toxins may contribute to symptoms and long-term complications in patients on dialysis. Two dialysis techniques are commonly used to improve toxin removal beyond standard hemodialysis: expanded hemodialysis (HDx) using medium cut-off membranes, and high-volume online hemodiafiltration (HV-OL-HDF). Although both techniques are effective, the best way to prescribe expanded hemodialysis-particularly the ideal treatment time-has not been clearly defined. The purpose of this study is to compare how well different treatment times of expanded hemodialysis remove small and medium-sized uremic toxins, and to compare these results with high-volume online hemodiafiltration. Toxin removal will be evaluated using a combined measurement called the Global Removal Score, which summarizes the removal of several important waste substances. This is a single-center, randomized, open-label, crossover study. Adults receiving maintenance hemodialysis will receive three different expanded hemodialysis sessions with different treatment durations (180, 210, and 240 minutes), followed by one session of high-volume online hemodiafiltration. Blood samples will be taken before and after each dialysis session to measure toxin levels. The results of this study may help determine whether expanded hemodialysis with shorter or standard treatment times can achieve toxin removal similar to high-volume hemodiafiltration, which could support more personalized and practical dialysis prescriptions.

Home dialysis is encouraged in Canada and peritoneal dialysis is the most common home dialysis method. However, many patients discontinue peritoneal dialysis, often transferring to hemodialysis. Despite the frequency of this transition, little is known about its impact on patients. Overall, the UPLIFT-PD program aims to fill this gap by studying the transition from peritoneal dialysis to hemodialysis. The specific goal of this mixed methods sub-study is to conduct a national survey to ask patients and caregivers about priorities and preferences when they anticipate a transfer from peritoneal dialysis to hemodialysis. This survey will be co-created by patient-partners and dialysis experts. Results from this survey will then be used in other phases of UPLIFT-PD program, detailed in other registrations, which will support people facing a transition from peritoneal dialysis to hemodialysis..

This study will compare the impact of two hemodialysis techniques on fatigue and post-dialysis recovery time in patients aged 85 years and older. These two techniques are high-flux hemodialysis (HD) and hemodiafiltration (HDF). Patients will receive the treatment over two periods: if period 1 is HD then period 2 will be HDF. Every patient will be his/her own control, this is why it is called cross-over. Each period will last three months. Between the two periods, patients will receive a traditional low-flux hemodialysis. These two techniques are widely used worldwide and their side-effects are well-known and do not put the patients at risk. HDF has been shown to improve survival in patients with a mean age of 58 years. But a previous study from the investigators' group showed that HDF causes a prolonged recovery time in older patients. This randomized trial aims to elucidate this question.

This quasi-experimental study aims to evaluate the effect of combined autogenic relaxation and Surah Ar-Rahman murottal therapy on anxiety, sleep quality, and hemodynamic parameters in hemodialysis patients. A pretest-posttest control group design will be used involving 76 participants undergoing routine hemodialysis. Participants will be assigned to an intervention group receiving structured autogenic relaxation followed by murottal therapy and a control group receiving standard care with music listening. Anxiety, sleep quality, and hemodynamic parameters will be measured at baseline and after a 6-week intervention period. The findings are expected to support the use of non-pharmacological and spiritual-based interventions in improving psychological and physiological outcomes in hemodialysis patients.

Chronic Kidney Disease (CKD) has a strong association with chronic periodontitis, an oral disease causing tooth loss linked to inflammation and malnutrition. While periodontitis affects 12.7% of the general population, its prevalence can rise to 39% in certain racial groups, and a dose-response relationship exists with CKD. End Stage Renal Disease (ESRD) patients show a prevalence of periodontitis ranging from 29% to 85.6%. Uremia, immunosuppression, and vitamin D deficiency are suggested factors in the etiology of periodontitis in CKD patients, with uremic toxins potentially altering the oral ecosystem. Periodontitis involves bacterial biofilm and Gram-negative anaerobes as primary etiological factors. The main treatment goal is to reduce periodontal pathogens and control inflammation, with non-surgical periodontal therapy (NSPT) being the standard. Although various adjuncts like antibiotics and antiseptics are suggested, recent guidelines only recommend certain locally administered agents and systemic antibiotics for specific groups due to increasing bacterial resistance. Alternative treatments like honey have gained interest, particularly Manuka honey, known for its antibacterial properties against antibiotic-resistant bacteria. This honey's effectiveness is due to its high sugar concentration, low pH, and formation of hydrogen peroxide. Manuka honey's unique component, methylglyoxal (MGO), is a potent bactericide, virucide, and fungicide, linked to its Non-Peroxide Activity (NPA) and Unique Manuka Factor (UMF) rating. MGO also has immunomodulatory effects beneficial for wound healing and tissue regeneration. Previous studies show Manuka honey as a promising adjunct in NSPT, improving outcomes significantly without adverse effects. Ongoing research aims to evaluate its effects in ESRD patients on hemodialysis, focusing on clinical attachment levels, other periodontal parameters, and FGF 21 levels in gingival crevicular fluid.

The goal of the CSP-2002 clinical trial is to evaluate the safety and effectiveness of the InnAVasc Arteriovenous Graft (IG) for hemodialysis (HD) access in patients with end-stage renal disease (ESRD). The primary study endpoints are: Primary Effectiveness Endpoint: The proportion of subjects with secondary patency at 6 months. Primary Safety Endpoint: The incidence of device-related adverse events of special interest (AESIs) through 6 months. Participants will be asked to sign an informed consent form. Once enrolled, they will be assessed to receive the study graft implant and asked to participate in periodic follow-up visits and assessments through 2 years following implant.

Physical activity is defined as 'any bodily movement produced by skeletal muscles that results in an energy expenditure greater than that of the resting metabolism'. Physical activity includes 'activities of daily living, physical exercise and sporting activities'. The scientific community is agreed in recognising the benefits of physical activity, both in healthy individuals and in those suffering from chronic diseases. With this in mind, the law of 2 March 2022 allows doctors to prescribe Adapted Physical Activity. In the case of chronic renal failure, there are a number of factors that can limit physical activity in haemodialysis patients, such as anaemia, nutritional status and post-dialysis fatigue. However, the risks associated with a sedentary lifestyle play a role in the development of chronic disease, in particular hypertension and diabetes. The benefits of physical activity have been widely identified in chronic renal failure, particularly in terms of cardiovascular and muscular function. More generally, physical activity has a positive impact on physical, psychological and social quality of life (increase in overall quality of life score, improved sleep, reduced pain, etc.). Physical activity should therefore be encouraged in patients with chronic renal failure, whether on dialysis or not, whatever their age. The aim of this study is to assess whether individualised support (from an advanced practice nurse and an adapted physical activity teacher) improves the practice of physical activity at home in patients who have been on haemodialysis for less than a year, and whether this improvement is sustainable over time.
