Mechanisms of Intradialytic Hypertension
Renal Failure Chronic Requiring HemodialysisHaemodialysis-induced Symptom1 morePatients with end-stage renal disease (ESRD) are at significantly higher risk for death due to cardiovascular disease. Those with paradoxical increases in blood pressure (BP) during hemodialysis (HD), defined as intradialytic hypertension (IDH), are at even greater risk of cardiovascular mortality. This study seeks to determine the mechanisms that underlie IDH, and whether mindfulness meditation might improve BP during dialysis in these patients. The investigators will first determine if increased adrenaline levels during volume removal contributes to IDH. The investigators will then determine lack of suppression of adrenaline levels in the setting of a high BP also contributes to IDH. This will be done by manipulating blood pressure by using small amounts of vasoactive drugs, and determining if an appropriate response in adrenaline levels occurs. Lastly, the investigators will determine if an intradialytic mindfulness meditation program improves BP and adrenaline levels in ESRD patients with IDH.
Calorimetry, Insulin Resistance and Energy Metabolism Study to Understand the Risk of Obesity in...
Chronic Renal FailureKidney Transplantation3 moreWeight gain is a common complication after transplantation. It has adverse effects such as hypertension, dyslipidemia, and insulin resistance. Weight gain is implicated in the increased cardiovascular risk and the long-term loss of graft function. Weight loss achieved by a suitable dietary intervention in these patients transplanted kidney can correct lipid disorders and facilitate balance blood pressure. The identification of mechanisms responsible for weight gain would suggest prevention strategies and allow to align the caloric energy needs of renal transplant patients.
The Feasibility and Safety of an Intradialytic Exercise Program: DIALY-SIZE
End-stage Renal DiseaseThe primary aim of this pilot study is to evaluate the feasibility and safety of four different types of intradialytic exercise (exercise performed during dialysis) programs: resistance, aerobic, combined resistance and aerobic, and flexibility (attention control). The secondary aim of the study is to estimate the effect of aerobic and resistance exercise, each compared with the attention control on: health-related quality of life, tests of physical performance, strength, and physical activity outside of the dialysis unit. The results of this study will be used to inform the planning of a full-scale efficacy study.
Pilot PK/PD Study of DS-1093a in Patients With Chronic Kidney Disease
Chronic Renal DiseaseRenal AnemiaDS-1093a is an inhibitor of hypoxia-inducible factor prolyl hydroxylases, and is expected to produce transient dose / exposure dependent increases in erythropoietin levels in subjects with chronic kidney disease (CKD). This study will be conducted in 2 parts. Part A will involve subjects with stage 3b or 4 CKD, and will be an open, non-controlled parallel group investigation of three single doses of DS-1093a (6 subjects/dose), in which allocation to dose will be randomised. On completion of this part of the study an optional fourth dose may be tested to gain a more complete understanding of the PK/PD behaviour of DS-1093a. Part B will be an open, non-controlled investigation of a single dose of DS-1093a in CKD subjects (n=6) receiving haemodialysis. The dose for Part B will be determined based on the data from Part A.
Investigating the Effectiveness of Intradialytic Massage on Cramping in Dialysis Patients
End Stage Renal DiseasePrimary Aim. The primary aim is to determine the effectiveness of intradialytic massage on the frequency and severity of cramping among hemodialysis patients prone to lower extremity cramping during treatment. Hypothesis: Compared to control patients, intervention patients will be significantly less likely to have intradialytic cramping that requires staff intervention or treatment termination. This is a study involving 32 (16 intervention, 16 control) hemodialysis patients with frequent lower extremity cramps during treatment. Frequent cramping during dialysis treatments is defined as 1 or more episodes of lower extremity cramps during or after dialysis over the previous 2 weeks. Cramping frequency will be determined by chart notes. Muscle cramping is defined as contraction of the large muscle group of the lower extremities sufficiently painful to require intervention by the dialysis staff for relief. The intervention group will receive a 20 minute massage of the lower extremities by a trained and licensed massage therapist during each treatment (3x per week) for 2 weeks. The control group will receive usual care by dialysis center staff.
Evaluation of a Marine OXYgen Carrier: HEMO2Life® for hypOthermic Kidney Graft Preservation, Before...
End Stage Renal DiseasesKidney transplantation is the treatment of choice for end stage renal diseases, increasing life expectancy and quality of life. Improvement in organ preservation is a critical issue in this context. This is a safety study evaluating the use of an oxygen carrier HEMO2Life® as an additive in organ preservation solution in kidney transplantation.
Effects of Oral Sodium Bicarbonate Supplementation in Haemodialysis Patients (BicHD)
End-stage Renal DiseaseThe purpose of the study is to investigate whether oral sodium bicarbonate supplementation to ensure a constant bicarbonate profile in haemodialysis patients will primarily lower predialysis potassium levels and secondary lead to improvements in cardiac function, muscle mass and dialysis related symptoms.

DiaSport - Endurance-orientated Training Program With Children and Adolescents on Maintenance Hemodialysis...
End Stage Renal Failure on DialysisPhysical activity is considered essential for optimal health, development, socialization and well-being of children. However patients with end-stage renal disease (ESRD) are often restricted from participation in exercise activities. This is especially true for children on hemodialysis (HD). As a consequence their exercise capacity is reduced, both before, but most impressively after HD. In a nationwide randomized, multi-center design this study aims to proof the influence of an individualised endurance training program by bicycle ergometer performed during dialysis on the efficacy of HD, measured as single pool Kt/V. Secondary goals are to enhance physical performance, physical and mental well-being, and to improve measurable blood and treatment parameters (e.g. haemoglobin level, amount of medication). A positive impact of physical activity was observed in adults on HD, although most studies did not address this issue in a randomised protocol. Despite this beneficial evidence in adults, sport is still not integrated as part of standard care in patients on maintenance HD. The study protocol, developed in close collaboration with the German Sport University Cologne, differs substantially from previously published reports as it uses bicycle ergometer training in an upright position outside the dialysis couch and adapts the intensity of intervention to the patient's capabilities. Based on the expected results the investigators will develop an individualised training program to be integrated in the standard care of (pediatric) patients on maintenance HD.
Intradialytic Exercises During Hemodialysis
Kidney FailureChronicAim. To investigate the effect of an intradialytic aerobic and resistance cycling exercise program (IARCEP) on depression, fatigue, and quality of life (QOL) in end-stage renal disease (ESRD) patients receiving haemodialysis, and further determine the effect of mediation through self-efficacy and resilience in patients receiving the IARCEP. Background. Depression and fatigue are common in ESRD patients undergoing haemodialysis, which negatively affects their QOL. Exercise can mitigate this effect. Patient's self-efficacy and resilience may be crucial mediators in exercise. Design. This study was a randomised controlled trial. Method. Seventy-six participants were randomly assigned to either a control or exercise group. Both groups received routine care; whereas the exercise group participated the 3- months IARCEP. Data were collected at baseline, the first, second, and third months, over a 14 months in 2013-2014.
