Sodium Deposition in Soft Tissues of Patients with Kidney Disease

Haemodialysis Complication

Sodium (Na+) hemostasis is abnormal in CKD patients, and this element can be deposited in the skin, muscle, and skeleton - to cope with long term sodium loading. It is known that sodium stored in this non-osmotically active way, is profoundly inflammatory. Furthermore, inflammation has been associated with several uremic symptoms. The investigators will use novel Na+ MRI imaging to examine the Na+ deposition in the skin, muscle, and skeleton of five groups:1) chronic in-center hemodialysis patients, 2) chronic peritoneal dialysis patients, 3) adult and paediatric patients with CKD stage 1-5 and 4) heart failure patients with and without renal dysfunction 5) sex and age-matched healthy adult and paediatric controls. Additionally, they will investigate the association between sodium deposition in these tissues with uremic symptomatology and biochemical markers of metabolism.
