Brief Summary

Sleep disturbance is a significant issue in people undergoing dialysis. More than 80% of haemodialysis patients complain of difficulty sleeping. Inadequate sleep can cause poor daytime function and increased risk of motor vehicle incidents. One of the common reasons for sleep disturbance in dialysis patients is sleep apnoea. Sleep apnoea involves pauses in breathing that occur during sleep. Each pause can last only a few seconds or minutes. Severe sleep apnoea reduces oxygen supply and increases risk of heart attack and stroke, which are the leading causes of death in dialysis patients. In this project, the investigators will examine how a change of dialysis treatment might improve sleep. This project will first identify patients at risk of sleep disturbance using surveys and a subsequent sleep study. The investigators will then test different dialysis models to see the effect of dialysis treatment on sleep apnoea. The aim is to find a dialysis model that works better for patients with sleep apnoea.

Outcome Measures

Primary Outcomes (1)

  • Severity of Sleep Apnea measured by Apnea-hypopnea index

    The Apnea-Hypopnea Index (AHI) score will be used to determine the severity of sleep apnea. The AHI will be obtained via an overnight sleep study. An AHI score of 5-14.9/hr is classified mild sleep apnea, 15-29.9/hr is moderate and above 30/hr is severe sleep apnea.

    18 months

Secondary Outcomes (4)

  • Patient-reported sleep quality measured by PSQI

    18 months

  • Patient-reported daytime sleepiness measured by ESS

    18 months

  • Overall quality of life measured by KDQoL-36

    18 months

  • The different concentration of inflammatory biomarkers (CRP, β2M, TNF-α, IL-6 and IL-8) during HDF period vs HD period, and the correlation to AHI, and overall sleep quality and quality of life.

    18 months

Study Arms (2)

Haemodialysis

ACTIVE COMPARATOR

regular convectional haemodialysis 3times/weekly

Procedure: Haemodiafiltration post-dilution model

Haemodiafiltration

ACTIVE COMPARATOR

post-dilution haemodiafiltration

Procedure: Haemodialysis

Interventions

Participants will be randomly assigned into either HD or HDF group. The participants will received the assigned treatment for 2 months, 1 month wash-out (HD) and cross-over to the other dialysis model- eg. HDF (2months) and switch to HD for 2 months, with 1 month washout period (using standard HD). Haemodialysis post-dilution model will be delivered using fresenius 5008 machine. Prescription for HDF post-dilution will be comparable to HD.
