Hyperglycemia improved but glucose production increased by Inhibition of kidney glucose transport

Treatment of patients with (T2D) with the drug metformin greatly reduces diabetic complications and mortality.

Unfortunately, many patients on metformin therapy become hyperglycemic, which exacerbates insulin resistance and reduces ? cell function.

Dugs that target the sodium-glucose cotransporter-2 (SGLT2), which promotes glucose absorption in the kidney have been attractive for use a add-ons to metformin treatment.

In this issue of theJournal of Clinical Investigation, two research groups led by Ralph DeFronzo of the University of Texas and of the University of Pisa independently report on clinical studies testing the ability SGLT2 inhibitors to reduce in T2D patients. SGLT2 inhibition increased glucose excretion in the urine (glycosuria), lowered fasting plasma glucose, and improved tissue . Surprisingly, the use of SLGT2 inhibitors resulted in an increase in endogenous and decreased insulin secretion, though overall pancreatic ? cell function was improved.

In a companion Commentary, of the Pennington Biomedical Research Center discusses the implications of these clinical studies for the future of T2D treatment.
