DiaSport - Endurance-orientated Training Program With Children and Adolescents on Maintenance Hemodialysis (DiaSport)
6. november 2017 oppdatert av: Prof. Dr. B. Hoppe, University Hospital, Bonn
DiaSport - Ausdauerorientiertes Trainingsprogramm Mit Kindern Und Jugendlichen an Der Dialyse (DiaSport - Endurance-orientated Training Program With Children and Adolescents on Maintenance Hemodialysis)
Physical 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.

Eksperimentell: Bicycle-Ergometer Training Group
Performance adapted, hence individualised three times weekly bicycle-ergometer training during hemodialysis. Each training will last 30 to 50 minutes, with 70-80% of the patient specific maximum workload over 12 weeks (36 training sessions). In the second part of the study intervention will be prolonged for another 12 weeks. |

Each training will last 30 to 50 minutes with 70-80% of the patient specific maximum workload over 12 weeks (36 training sessions - first part of the study compared to no intervention). In the second part of the study both groups get the opportunity for another 12 weeks of individualised three times weekly bicycle-ergometer training during hemodialysis. |

Annen: Control
No intervention during hemodialysis during the first 12 weeks of the study. In the second part of the study a training program, according to that of the intervention group, will be performed with a performance adapted, hence individualised three times weekly bicycle-ergometer training during hemodialysis. Each training will last 30 to 50 minutes, with 70-80% of the patient specific maximum workload over 12 weeks (36 training sessions). |

Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
Change of single pool Kt/V (KDOQI Guidelines) - expressed as the change of single pool Kt/V from week 0 to 12 of intervention (period 1)
Tidsramme: 12 weeks
|
Change of single pool Kt/V (spKt/V) measured at week 12 (V1) compared to baseline (V0).
Single pool Kt/V is the standard measure to assess dialysis efficacy.
As dialysis efficacy is the primary aim of dialysis treatment and the spKt/V is the best way to measure efficacy this figure has an important clinical relevance for the patient.

Tidsramme |

|
Change of the possible workload (maximum physical performance) achieved
Tidsramme: 12 and 24 weeks
|
The maximal possible workload will be determined by an exercise evaluation program with increasing power on a leg bicycle ergometer before a hemodialysis session, measuring the peak oxygen uptake (VO2-peak), heart rate, blood pressure and lactate levels during exercise.
|
12 and 24 weeks

|
Quality of Life
Tidsramme: 12 and 24 weeks
|
For quality of life assessment the validated and standardized PedsQL® questionnaires will be filled in by patients and parents.

Change of solute removal during hemodialysis
Tidsramme: 12 and 24 weeks
|
Solute removal during hemodialysis has a clear impact on the patient's health and well-being, as it reduces sequelae and offers the patient less restrictions on their diet, which would lead to a better compliance.
|
12 and 24 weeks
|
|
Change of solute removal in the two compartment model (assessed in a subgroup of patients)
Tidsramme: 12 and 24 weeks
|
Solute removal in the two compartment model will only be analyzed in patients 12 years of age or older with explicit consent to a second blood drawing 30 minutes after end of hemodialysis session.
It was previously used showing a significant enhancement during exercise, explained by an increase of skeletal muscles perfusion during exercise.

12 and 24 weeks

Inflammation, nutritional status and bone metabolism
Tidsramme: 12 and 24 weeks
|
The nutritional status and bone metabolism will be determined as they are important for optimal health and growth of paediatric hemodialysis patients.
Evidence is based on studies that showed trends towards a better nutritional status and less chronic inflammation.
|
12 and 24 weeks

Body Composition Monitoring (BCM)
Tidsramme: 12 and 24 weeks
|
Body Cpomposition Monitoring (BCM) will be performed to exermine further information on nutrional status, overhydration and muscle growth.
|
12 and 24 weeks
|
|
Change of number and dose of medication needed
Tidsramme: 12 and 24 weeks
|
Number and dose of medication will be recorded, changes will be evaluated, and data will be correlated to e.g. the measured blood pressure (antihypertensive drugs) or haemoglobin levels (EPO or EPO stimulating agents).
