THU387 Euglycemic Diabetic Ketoacidosis And SGLT-2 Inhibitor Use

Disclosure: N. Abrahimi: None. A. Abrahimi: None. N. Terrigno: None. Background: Diabetic ketoacidosis (DKA) is a known adverse effect of SGLT-2 inhibitors. (1) Incidences of euglycemic diabetic ketoacidosis in patients on SGLT-2 inhibitors are reported on less. Clinical Case: A 39-year-old male past medical history of uncontrolled, non-insulin dependent diabetes mellitus and pancreatitis who presented with abdominal pain, nausea and coffee ground emesis. On initial work up, basic metabolic panel showed blood glucose level of 175 mg/dL with an elevated anion gap of 22 mmol/L. Initial differentials included suspicion for euglycemic diabetic ketoacidosis or acute intraabdominal pathology. Venous blood gas showed metabolic acidosis, with a pH of 7.21 and bicarbonate of 9.7 mmol/L, beta hydroxybutyrate was elevated at 7.83 mmol/L. CT abdomen pelvis found a small hiatal hernia, gastric wall thickening, likely gastritis, and was negative for other intraabdominal pathology. Home medications of the patient included dapagliflozin, semaglutide, metformin, gabapentin, and pantoprazole. Patient was admitted with the diagnosis of suspected euglycemic diabetic ketoacidosis and was started on an insulin drip along with D5 0.45 normal saline. Patient’s anion gap was monitored with basic metabolic panel orders every two hours. The insulin drip was discontinued once the patient had two consecutive normal anion gaps and the patient was subsequently started on a subcutaneous insulin regimen. Conclusion: SGLT-2 inhibitors may cause euglycemic diabetic ketoacidosis based on the physiology of the SGLT-2 transporter and the pharmacology of the SGLT-2 inhibitors. (2) Clinical importance of this case report is to consider euglycemic diabetic ketoacidosis in patients on SGLT-2 inhibitors presenting with nausea, vomiting with normal blood glucose to not delay in the diagnosis and treatment of this life-threatening condition.
