THU360 Hyperglycemic DKA In Patient On Monotherapy With SGLT-2 Inhibitor

Disclosure: S. Ahmed: None. L. Medina Mora: None. A. Sanchez Ruiz: None. L. Poretsky: None. Background: SGLT2 inhibitors have a rare but increasingly reported risk of euglycemic diabetic ketoacidosis. Hyperglycemic diabetic ketoacidosis is not an expected risk of SGLT-2 inhibitors. Clinical Case: 52-year-old male with history of type 2 Diabetes presented with progressive weakness, shortness of breath, nausea and vomiting worsening over 48 hours. He reported increased polydipsia and polyuria. Patient was found to have a blood glucose of 685 mg/dL associated with an anion gap of 28 mm/L and bicarbonate level of 6 mm/L. Beta hydroxybutyrate level was >8.0 mmoL/L. He was diagnosed with hyperglycemic diabetic ketoacidosis, given intravenous isotonic fluid and started on an insulin drip. The anion gap closed and he was successfully transitioned off the insulin drip to a basal bolus regimen of insulin. The patient improved quickly without any complication. The patient was never on insulin therapy prior to admission. No obvious source of infection was discovered to precipitate the event. The patient had a 7-year history of diabetes and was only managed on oral medications at home. He was previously on Janumet 50-1000mg twice a day and changed to only dapagliflozin 10mg 9 months prior to the current episode. He never experienced ketoacidosis or hyperosmolar hyperglycemic state. Hemoglobin A1c was found to be 8.0%. He reported that his A1c levels were always less than 8%. Autoimmune workup for type 1 Diabetes was done. C-peptide level was found to be 1.5ng/mL. Patient appeared to have an adequate insulin level despite the recent event of diabetic ketoacidosis. Patient was discharged on 10 units of Glargine® at bedtime and 3 units of Lispro® before meals. He was given glucometer teaching with an appointment for endocrine follow up. During follow up Glutamic Acid decarboxylase, Islet cell, Insulin and Zinc 8 transporter antibodies have come back negative. Patient is being planned for transition to oral antihyperglycemic agents which will not include an SGLT2 inhibitor. A MODY panel is pending results for further evaluation. Conclusion: Monotherapy of SGLT-2 inhibitors appears to not only have a risk of euglycemic diabetic ketoacidosis but also a risk of hyperglycemic diabetic ketoacidosis in type 2 diabetics. In this case we presented a case of hyperglycemic diabetic ketoacidosis in a type 2 diabetic on therapy with dapagliflozin. Presentation: Thursday, June 15, 2023
