Abstract

Abstract Background: Euglycemic diabetic ketoacidosis (DKA) is a known complication of sodium-glucose cotransporter 2 (SGLT2) inhibitors. We report an unusual case of euglycemic DKA caused by an SGLT2 inhibitor during self-introduction of a ketogenic diet; initial concern was for acute coronary syndrome. Clinical Case: A 61-year-old man with a history of type 2 diabetes with a hemoglobin A1c of 8.3%, coronary artery disease, hypertension, and hyperlipidemia presented to the emergency room with nausea and chest pain. The patient had a 30-year history of diabetes and was on oral therapy for years before starting insulin with an average daily dosage of 28 units. Three years ago, he started an SGLT2 inhibitor, improved his lifestyle and glycemic control, and was able to stop insulin. His home medications included empagliflozin 10 mg daily, metformin 500 mg twice a day, liraglutide 1.8 mg subcutaneously daily, rosuvastatin 5 mg daily, ezetimibe 10 mg daily, and omeprazole 40 mg daily. He reported several weeks of atypical chest pain and computed tomography angiography showed total occlusion of the mid-right coronary artery. He underwent an exercise stress test that showed echocardiographic changes that were positive for ischemia and subsequently was scheduled to undergo a left heart catheterization in 1 week. In the interim, he was highly motivated to change his lifestyle. He adopted a ketogenic diet, significantly limiting his daily carbohydrate. Five days later, he developed…
