AbstractEuglycemic diabetic ketoacidosis (EDKA) is a rare variant of diabetic ketoacidosis which has been recently reported in association with sodium-glucose cotransporter 2 (SGLT-2) inhibitors. Empagliflozin, an agent belonging to this therapeutic class, was approved by the U.S. Food and Drug Administration (FDA) in 2014 for management of type 2 diabetes. Since then, sparse reports of its association with EDKA are emerging, similarly to its predecessors in the class. We report the case of a 58-year-old female who developed EDKA in the intensive care unit (ICU) 48 hours after her last intake of empagliflozin and a day after neurosurgery. Though expected to improve in the post-operative period, she developed a rapidly worsening and unexplained anion gap metabolic acidosis. She was eventually diagnosed with EDKA which was successfully treated with intravenous insulin infusion, dextrose-containing fluids and discontinuation of the offending drug. Metabolic abnormalities improved in less than 24 hours and patient recovered without complications. This report highlights the importance of recognizing EDKA as a complication of oral anti-diabetics and discontinuing SGLT-2 inhibitors days prior to surgery and ICU admission. Care should be applied to providing patient with low-dose ketogenesis-inhibiting basal insulin and close observation of laboratory values in order to minimize delays in diagnosis, prolonged hospital stays and complications of EDKA.
