About this trial

This study will compare the impact of two hemodialysis techniques on fatigue and post-dialysis recovery time in patients aged 85 years and older. These two techniques are high-flux hemodialysis (HD) and hemodiafiltration (HDF).

Patients will receive the treatment over two periods: if period 1 is HD then period 2 will be HDF. Every patient will be his/her own control, this is why it is called cross-over. Each period will last three months. Between the two periods, patients will receive a traditional low-flux hemodialysis.

These two techniques are widely used worldwide and their side-effects are well-known and do not put the patients at risk. HDF has been shown to improve survival in patients with a mean age of 58 years. But a previous study from the investigators' group showed that HDF causes a prolonged recovery time in older patients. This randomized trial aims to elucidate this question.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Signed and dated informed consent

Age >84 years

Diagnosed with kidney failure

On maintenance hemodialysis >3months

Disqualifiers

Patients with cognitive impairment (assessed with a mini-test if needed)

Trial design

Design model

Crossover

Treatments tested in this trial

  • High-flux hemodialysis

    Other intervention

    High-flux hemodialysis removes small and middle molecular solutes through the mechanism of diffusion.

  • Hemodiafiltration

    Other intervention

    Hemodiafiltration removes solutes using convection which allows for more epuration of middle molecular solutes.

Treatment groups

62 Participants

Trial outcomes

Primary outcomes

1

Change in dialysis recovery time

Time in minutes that the patient needs after dialysis to recover energy

Time frame
Three months

Secondary outcomes

1

Change in fatigue score

Fatigue will be assessed using the Standardized Outcomes in Nephrology (SONG) fatigue scale: from 0 to 9, higher meaning worse outcomes.

Time frame
Three months
2

Change in STS-30

The number of stand-to-sit over 30 seconds will be recorded. The higher the better outcome.

Time frame
Three months
3

Change in SF-12 scores

Quality of life scale (12 items), from 0 to 100, the higher the better outcome.

Time frame
Three months
4

Number of episodes of of symptomatic hypotension

Drop in blood pressure with symptoms

Time frame
Three months

Other outcomes
