Acute Effects of SGLT2 Inhibitor on Kidney Allograft Oxygen Tension

Summary

The goal of this clinical trial is to investigate if a single dose of oral SGLT2i, (50 mg Jardiance) will change oxygen tension in the kidney transplant. The main questions it aims to answer are: * Does a single dose of oral SGLT2i (50 mg Jardiance) change oxygen tension in the kidney transplant cortex and medulla, estimated by magnetic resonance imaging? * Does a single dose of oral SGLT2i (50 mg Jardiance) change kidney transplant cortical and medullary perfusion? * Does a single dose of oral SGLT2i (50 mg Jardiance) change kidney transplant artery blood flow? * Does a single dose of oral SGLT2i (50 mg Jardiance) change blood glucoses, blood pressure and heart rate? Researchers will compare a single dose of oral SGLT2i (50 mg Jardiance) to a placebo (a look-alike substance that contains no drug) to see if a single dose of oral SGLT2i (50 mg Jardiance) changes oxygen tension in the kidney transplant. Kidney transplant recipients with out diabetes will: * Meet for two intervention days. * A single dose of oral SGLT2i (50 mg Jardiance) or placebo will be given in random order, separated by at least 2 week washout period, the experiment will be repeated with the opposite treatment. * Kidney cortex oxygenation, and blood flow in different compartments of the kidney transplant, is estimated by blood-oxygen-dependent level magnetic resonance imaging (BOLD-MRI). Patients are evaluated by routine clinical examination and routine biochemical measures for kidney transplant patients.
