Acute Physiological Response to Exercise in End Stage Renal Disease (PRECISE)

Detailní popis
Chronic kidney disease (CKD) affects between 5-10% of the world's population, equating to ~740 million people worldwide. End stage renal disease (ESRD) is the result of a progressive loss of kidney function where the patient requires dialysis to replace the typical functions of the kidney. The quality of life (QOL) of these individuals is severely impaired as a result of various complications associated with CKD (e.g. heart disease, diabetes, muscle wastage, decreased fitness). In an attempt to combat this decrease in physical fitness, many studies have applied long term exercise interventions. However, the acute response to exercise in this population is not entirely understood and a comprehensive set of guidelines that informs safe and effective exercise prescription is lacking.
The use of exercise as a therapeutic intervention in ESRD has grown in popularity, and evidence provided by numerous long term studies indicates cardiopulmonary, metabolic and inflammatory system adaptations. Despite these positive findings, the specific mechanisms through which exercise benefits these patients have not yet been fully established. In addition, the extent to which 'normal' physiology is acutely altered by dialysis treatment, and the effect that aerobic exercise may have on this, is unknown.
In patients with ESRD, this study aims to characterise the acute physiological response to exercise under different conditions. In doing so, the study aims to inform the development of guidelines for safe and effective intra-dialytic exercise training.

Studijní populace
Participants with end stage renal disease:
Patients will be recruited from the University Hospitals Coventry & Warwickshire hemodialysis unit identified by the research team and renal medical professionals.
Healthy participants:
Healthy participants will be recruited from Coventry University database of previous research participants. This group will comprise of 20 participants, age and weight matched to the patients with ESRD.

Participants with end stage renal disease
Cardiopulmonary exercise test Cardiopulmonary exercise testing will be conducted on an electronically braked cycle ergometer using a ramped protocol with participants being required to pedal until exhaustion. Constant load exercise test Constant load exercise will be performed for 30 min on an electronically braked cycle ergometer whilst seated in a dialysis chair. Blood sampling and echocardiogram will be measured throughout. |
