26 - Euglycemic DKA triggered by Ketogenic diet- A theoretical concern or actual risk?

Objective :

Sodium-glucose co-transporter 2 (SGLT-2) inhibitors are increasingly used to achieve glycemic control in persons with Type 2 Diabetes (T2D). Diabetic ketoacidosis (DKA) occurring in conjunction with SGLT-2 inhibitor therapy have raised concerns, especially among patients taking exogenous insulin. We present an interesting case where a theoretical risk factor actually contributed to DKA in a patient on this treatment.

Case Presentation:


 35 years old male with 12 years history of DM-2 managed on metformin, glipizide and empagliflozin developed severe nausea, vomiting and fatigue. The symptoms were temporally associated with a recent initiation of a ketogenic diet for weight loss. He said he was aware of the risk and was keeping up with oral hydration for the past 2 weeks.  He was admitted to the hospital and was found to have the atypical presentation indicative of euglycemic DKA. He did not have any other comorbid acute illness. Laboratory studies were confirmatory- elevated blood ketones (B-hydroxybutyrate), serum glucose 92 mg/dL, anion gap -19 mEq/L, serum bicarbonate- 10 mEq/L and an arterial pH- 7.16. He had high urine glucose > 1000 mg/dL, and urine ketone >150 mg/dl. Serum lactic acid was normal. Empagliflozin was discontinued at admission. He responded well to IV hydration and insulin treatments. DKA resolved within 48 hours and he was discharged home on the other 2 oral agents and basal insulin. He has continued to do well on subsequent follow-up clinic visits.



Discussion:


SGLT-2 inhibitor- associated DKA occurs occasionally in individuals with diabetes especially those with depleted insulin reserves such as those with latent autoimmune diabetes in adults and Type 1 Diabetes. This most likely is due to non-insulin-dependent glucose clearance, hyperglucagonemia, and decreased ketone clearance. Intercurrent infections, myocardial infarction and excessive alcohol use also increase the risk for DKA. In our patient initiation of a ketogenic diet triggered euglycemic DKA.  


Conclusion :

Patients taking SGLT-2 inhibitors should avoid excess alcohol intake and very-low-carbohydrate/ketogenic diets. These may precipitate DKA even in the absence of other risk factors. This message should be an integral part of ongoing patient education during use of these medications.
