Euglycemic Diabetic Ketoacidosis Due to Canagliflozin in A Patient with an Uncertain Diagnosis of Type 2 Diabetes: A Case Report

Sodium-glucose cotransport 2 (SGLT2) inhibitors are approved for use only in patients with type 2 diabetes and work by blocking glucose reabsorption in the proximal renal tubule. There is also evidence that SGLT2 inhibitors directly act on pancreatic α-cells to stimulate glucagon secretion, leading to additional ketone body production, and that SGLT2 inhibitors decrease renal clearance of ketone bodies. While the risk of euglycemic diabetic ketoacidosis (eDKA) associated with offlabel use in patients with type 1 diabetes is well known, there are currently no guidelines for SGLT2 inhibitor use in patients with diabetes of uncertain or transitioning pathology. We report a case of eDKA associated with canagliflozin in a patient with rapid progression of noninsulin dependent to insulin-dependent diabetes within the span of 2 years to illustrate the risk of eDKA when SGLT2 inhibitors are used in patients with an uncertain insulin treatment requirement in T2D.
