Background: Renewed interest in ketone bodies has emerged, partly driven by the recent success of selective sodium glucose co transporter 2 (SGLT-2) inhibition in preventing cardiovascular deaths in patients with diabetes mellitus (DM) and chronic kidney disease (CKD). Effects of ketosis are of importance in order to understand the beneficial effects of SGLT-2 inhibitors and to account for the full therapeutic potential of this treatment.
Hypothesis: Ketosis decreases 24 hour systolic blood pressure and increases renal blood flow and glomerular filtration rate (GFR).
Methods: It is a randomized, placebo-controlled double-blinded cross over study. Nineteen patients with essential hypertension will be randomized to receive either ketone bodies (KE4) or for 5 days. After a wash out period of at least 14 days, the subjects are crossed over to receive the other treatment. After each treatment period effect variables will be measured including Technetium(Tc)99m - Diethylenetriamine pentaacetate (DTPA) clearance and water based positron emission tomography computed tomography (PET/CT)
Perspectives: The study has the potential to provide information regarding the therapeutic potential of treatment with ketone bodies and understanding of conditions characterized by ketosis, such as SGLT2-inhibitor treatment.
