Case Report: Euglycemic diabetic ketoacidosis led by empagliflozin: A case report and literature review

Abstract

Introduction: Sodium-glucose co-transporter 2 inhibitors (SGLT2i) are a new class of medications that have been approved for the treatment of heart failure (HF) in patients with and without type-2 diabetes mellitus. It is important to be aware of the likely side effects of SGLT2i for their optimal use and enhanced patient safety. One such rare but potential side effect is the development of euglycemic diabetic ketoacidosis (EDKA). Objective: We present a case report of EDKA, in a patient who was started on empagliflozin – one of the SGLT2i – highlighting its presenting signs and symptoms, pertinent laboratory findings, differential diagnosis, treatment and outcome. To strengthen our findings and hypothesis, we conducted a literature review of other cases that used SGLT2i and found similar complications. This case report with review can help recognize the serious, potentially life-threatening complications of the new class of medication SGLT2i that has been incorporated into the current practice, and also help to take appropriate steps to mitigate its adverse effects and improve overall health outcomes in our patients. Conclusions: SGLT2i are increasingly used because of their favorable effects on mortality in the chronic HF patients along with its benefits of weight loss and blood pressure reduction. A potential underdiagnosed adverse effect of SGLT2i use is diabetic ketoacidosis in a setting of normal blood glucose levels. Thus, it is reasonable to be cognizant of its side effects to prevent any untoward events in a timely manner.
