SASH: Sodium Accumulation Study In Haemodialysis (SASH)
Sodium Accumulation Study In Haemodialysis
Studieoversikt
Status
Intervensjon / Behandling
Detaljert beskrivelse
It has been proposed that tissue sodium accumulation in skin and/or muscle is a key factor in hypertension. 23Na MRI allows the assessment of skin and muscle sodium storage and will therefore be a valuable tool in elucidating the role of tissue sodium accumulation in the pathogenesis of salt-sensitive hypertension and cardiovascular morbidity and mortality. Moreover, if haemodialysis in patients with end-stage kidney disease (ESKD) results in changes in tissue sodium, the development of 23Na skin and muscle measures would allow for a method to correlate skin tissue sodium content with detailed cardiovascular and functional assessments.
Participants will have a single haemodialysis session, and undergo two MRI scans (one prior to and one following dialysis), in conjunction with clinical data collection (eg. blood samples, bioimpedance analysis, skin autoflorescence).
