Peritoneal Dialysis (PD)

This is an observational study to see how a simple test can be used to check if fluid in the chest cavity contains starch. Some people with kidney failure have dialysis treatment by putting fluid in the tummy cavity, and sometimes the fluid can leak into the chest cavity. Iodine can change the colour of starch based dialysis fluid, so this test could be used to diagnose fluid leaking from the tummy cavity into the chest cavity. The investigators are doing this study to ensure the fluid doesn't change colour for other reasons.

Peritoneal dialysis (PD) uses the peritoneal membrane as a natural filter to remove waste products from the blood in patients with kidney failure. Over time, the peritoneal membrane can become scarred and less functional - a process called peritoneal fibrosis - which eventually leads to ultrafiltration failure and loss of the PD technique. Currently, there is no reliable early biomarker to detect this process before it causes clinical problems. PERIMARK is a prospective, single-center, observational study investigating whether DKK3 (Dickkopf-3), a protein involved in fibrosis signaling, can serve as an early biomarker of peritoneal membrane deterioration. DKK3 will be measured in urine, peritoneal dialysate and serum at four time points over 12 months (T0: catheter insertion; T1: 12 weeks; T2: 6 months; T3: 12 months). At each follow-up visit, peritoneal membrane function will be assessed by the Modified Peritoneal Equilibration Test (Modified PET) with 3.86% glucose, measuring the sodium dip (ΔDNa) as a marker of aquaporin-1-mediated water transport and D/P creatinine as a marker of small solute transport. The primary endpoint is the intraindividual change in DKK3/creatinine ratio in urine, dialysate and serum from baseline to 12 months. Secondary endpoints include the correlation of DKK3 with the sodium dip, longitudinal changes in peritoneal transport parameters, and the exploratory question of whether an early DKK3 rise predicts a later decline in aquaporin-1 function. The study also includes a biobank of serum, urine, dialysate supernatant and cell pellets for possible future analyses. Target enrollment is 25-30 patients.

To evaluate the impact of an integrated remote patient monitoring model on clinical, operational, and health-economic outcomes for patients receiving APD

This prospective, multicenter observational study will evaluate glucose profiles using continuous glucose monitoring (CGM) in 100 adults with diabetes receiving peritoneal dialysis (PD) or planning to start PD within 3 months. The study will examine associations between CGM metrics and PD regimen, glucose-lowering treatment, conventional glycemic markers, dialysis-related measures, and clinical outcomes including glycemic emergencies, hospitalizations, cardiovascular events, and mortality over 12 months.

The goal of this clinical trial is to learn if synbiotics work to lower inflammation in adults with chronic kidney disease who are on peritoneal dialysis. Synbiotics are daily capsules that contain a mix of probiotics (good bacteria) and prebiotics (fiber that feeds good bacteria). The main questions it aims to answer are: Do synbiotics lower the level of inflammation markers in the blood? Do synbiotics improve the nutritional status of the participants? Do synbiotics lower the number of peritonitis (peritoneal infections) episodes? Researchers will compare synbiotics to a placebo to see if the treatment works. A placebo is a look-alike capsule that contains no active ingredients. Participants will: Take 1 capsule every day for 6 months Visit the clinic at the start, at 3 months, and at 6 months for blood tests and nutrition checkups

Kidney failure is fatal without dialysis. Peritoneal dialysis (PD) completed at home offers greater flexibility and autonomy for patients . However, PD is often prescribed for 24 hours/day, 7 days/week for every patient starting dialysis. This practice is not evidence-informed, may be unnecessary and potentially harmful. The STEP-PD trial aims to determine the optimal approach to commencing patients on PD through starting at low dose PD and incrementing over time.

To explore the use of the Bodyport Cardiac Scale in predicting worsening of events due to fluid overload in patients with kidney disease on peritoneal dialysis.

The goal of this clinical trial is to determine whether a plant-focused diet improves nutritional and health outcomes of malnourished adults undergoing peritoneal dialysis (PD). It will also learn about the safety of this diet in this population. The main questions it aims to answer are: 1. Does a plant-focused diet improve nutritional status compared to a standard kidney diet in PD patients? 2. What changes occur in anthropometric, biochemical, and dietary measures over 6 months? Researchers will compare the plant-focused diet to a standard-of-care renal diet to see which is more effective in improving nutrition in PD patients. Participants will: * Be randomly assigned to follow the plant-focused diet or the standard diet. * Be monitored for 6 months through in-person visits (aligned with their routine clinic appointments) and virtual check-ins via messages or calls. * Have their progress monitored for changes in outcomes such as nutrition, blood tests, kidney function, and quality of life.

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..

The main goal of this study is to assess whether a mobile phone app called MiDiálisis is practical, easy to use, and well-accepted. The app was developed by the Technical University of Madrid (UPM) and is designed to bring together the clinical data of people with chronic kidney disease who are on peritoneal dialysis. This way, both patients and doctors can access the information at any time.

This is a prospective multicenter randomized controlled clinical study. The goal of this clinical trial is to learn if intravenous iron isomaltoside injection use is equally effective and safe for the treatment of renal anemia in peritoneal dialysis patients compared with oral ferrous succinate tablets. The main questions to answer are: * Changes in hemoglobin concentration from baseline to week 8 after the use of single dose intravenous iron isomaltoside injection in peritoneal dialysis patients with renal anemia. * If intravenous iron isomaltoside injection use is equally effective and safe for the treatment of renal anemia in peritoneal dialysis patients compared with oral ferrous succinate tablets. Participants will: * be randomized 1:1 to two groups, either Iron isomaltoside Group (Group A, experimental group) or Ferrous succinate Group (Group B, control group). * Patients in Iron isomaltoside Group will receive a single dose of intravenous iron isomaltoside injection, the dose of which is set at 1000 mg. Patients in Ferrous succinate Group will receive ferrous succinate treatment orally given as 200mg twice a day for 8 weeks (containing iron element 7840mg in total). * Patients will be followed up for 8 weeks.
