155-LB: The Increase in Endogenous Glucose Production with SGLT2 Inhibition Is Unchanged by Renal Denervation but Highly Correlates to Urinary Glucose Excretion
Abstract
Background: SGLT2 inhibition causes a “paradoxical” increase in EGP, indicating the presence of a “reno-hepatic axis.” Aim: We measured EGP after SGLT2 inhibition in renal transplant subjects with and without type 2 diabetes to evaluate the role of renal nerves and SNS in mediating this “reno-hepatic axis.” Six T2D (A1c = 7.2±0.1) and 8 non-T2D (A1c = 5.6±0.1) with normal renal function and no history of rejection (prednisone ≤ 5mg/day) received two 6-hr measurements of EGP preceded by dapagliflozin or placebo. Results: Following DAPA in T2D, FPG (143±15 to 112±9 mg/dl, p=0.01) and FPI (14±3 to 11±2, p=0.02) decreased while glucagon increased (45±13 to 54±14 pg/mL, p=0.09) (all p Conclusions: (1) Renal denervation in renal transplant patients failed to block the DAPA-mediated stimulation of EGP; (2) DAPA-stimulated rise in EGP is strongly related to the increase in urinary glucose excretion blunting the decline in FPG.
