Autonomic Nervous System Dysfunction in Patients With End-stage Kidney Disease
Greece78 participantsStarted 2021-04-01
Plain-language summary
The prevalence of autonomic nervous system (ANS) dysfunction in patients with end-stage kidney disease (ESKD) is considered to be increased. The uraemic environment, as well as the high incidence of comorbid conditions affecting the ANS function (e.g. diabetes mellitus, autoimmune and degenerative neurological diseases), have been proposed to cause important alterations in ANS function. The vast majority of evidence on the prevalence of ANS dysfunction in ESKD patients is derived from small studies elaborating simple methodology. Noteworthy, with the exception of a study in 27 hemodialysis patients which assessed ANS function before and after dialysis in relation to left ventricular filling pressures, and a 2005 Dutch study in 21 patients whether or not they had hypotension during dialysis, no other study used advanced methods to analyze heart rate or blood pressure variability from beat-to-beat recordings, such as this study. In addition, there is no study so far investigating possible changes in the ANS function per dialysis session. Finally, to the best of our knowledge, this is the first work evaluating possible differences in ANS function in hemodialysis compared with peritoneal dialysis individuals.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
The difference in the root mean square of successive R-R differences [RMSSD (ms)] parameter of heart rate variability during the mental arithmetic test between the examination during the dialysis session and the examination in the out-of-dialysis day
