A Case of Euglycemic Diabetic Ketoacidosis in Patient with Type 2 DM

Diabetic ketoacidosis (DKA) can cause significant morbidity and mortality in patient with both type 1 and type 2 diabetes mellitus. A subset of DKA cases termed euglycemic diabetic ketoacidosis (EDKA) is characterized by euglycemic (<200 mg/dl), high anion gap metabolic acidosis, and increased plasma ketone concentration. This clinical syndrome is primary related to a general state of starvation, resulting in the development of ketosis while maintaining normoglycemia. It can lead to severe complication, such as extreme dehydration, altered mental status and coma. Early recognition and treatment are essential to avoid this life-threatening complication. EDKA represents approximately 2.6% to 3.2% of total DKA admissions, making it a rare condition. In this case report, a male patient was diagnosed with type 2 DM, 1 week prior to his symptoms and admission in hospital. Despite normal glucose levels at the time of presentation to the ED, he displayed severe acidemia and ketonemia, and was diagnosed with EDKA.
