Renal glucose reabsorption was measured with the stepped hyperglycemic clamp in 15 subjects with type 2 diabetes mellitus (T2DM) and 15 without diabetes after 2 days and after more chronic (14 days) treatment with empagliflozin. Patients with T2DM had significantly greater maximal renal glucose transport (TmG) compared with subjects without diabetes at baseline (459 ± 53 vs. 337 ± 25 mg/min; P < 0.05). Empagliflozin treatment for 48 h reduced the TmG in both individuals with and without diabetes by 44 ± 7 and 53 ± 6%, respectively (both P < 0.001). TmG was further reduced by empagliflozin in both groups on day 14 (by 65 ± 5 and 75 ± 3%, respectively). Empagliflozin reduced the plasma glucose concentration threshold for glucose spillage in the urine similarly in individuals with T2DM and without diabetes to <40 mg/dL, which is well below the normal fasting plasma glucose concentration. In summary, sodium-glucose transporter-2 inhibition with empagliflozin reduces both TmG and threshold for glucose spillage in the urine in patients with T2DM and those without diabetes.

Abstract

Renal glucose reabsorption was measured with the stepped hyperglycemic clamp in 15 subjects with type 2 diabetes mellitus (T2DM) and 15 without diabetes after 2 days and after more chronic (14 days) treatment with empagliflozin. Patients with T2DM had significantly greater maximal renal glucose transport (TmG) compared with subjects without diabetes at baseline (459 ± 53 vs. 337 ± 25 mg/min; P < 0.05). Empagliflozin treatment for 48 h reduced the TmG in both individuals with and without diabetes by 44 ± 7 and 53 ± 6%, respectively (both P < 0.001). TmG was further reduced by empagliflozin in both groups on day 14 (by 65 ± 5 and 75 ± 3%, respectively). Empagliflozin reduced the plasma glucose concentration threshold for glucose spillage in the urine similarly in individuals with T2DM and without diabetes to <40 mg/dL, which is well below the normal fasting plasma glucose concentration. In summary, sodium-glucose transporter-2 inhibition with empagliflozin reduces both TmG and threshold for glucose spillage in the urine in patients with T2DM and those without diabetes.
