CANagliflozin In DIALysis Patients

Rationale: Sodium glucose co-transporter 2 (SGLT2) inhibitors are a relatively new class of drugs originally developed for the treatment of diabetes. Cardiovascular outcome trials with these drugs showed also beneficial effects of these agents on heart failure, cardiovascular disease and kidney outcomes. Secondary analyses from these trials demonstrated that these benefits were consistent in patients with or without type 2 diabetes and with or without chronic kidney disease (CKD) with a lower eGFR threshold of 20 mL/min/1.73m2. However, it is not yet clear if these drugs can also be used in patients with severe kidney disease who require dialysis. This is in part explained because SGLT2 inhibitors bind to a transporter which is located in the luminal side of proximal tubes in the kidney. If kidney function is low, and these patients have no or limited filtering capacity, it is possible that the efficacy of these drugs decrease. Notwithstanding, several animal experiments and preliminary clinical data have suggested that these drugs do have kidney and cardiac protective effects in case of severely decreased kidney function. The investigators hypothesize that SGLT2 inhibitors are distributed to several tissues in the body on top of the kidney and therefore the investigators would like to investigate the specific tissue distribution of SGLT2 inhibitors in patients on dialysis with-and without residual diuresis.
