Normoglycemic diabetic ketoacidosis in a type 2 diabetes patient on dapagliflozin: A case report.

A 48-year-old male patient with Type 2 diabetes mellitus(T2D), on insulin replacement therapy, glipizide, and dapagliflozin presented with generalized weakness with weight loss of 40 pounds in 6 months ever since he was started on dapagliflozin. He was hemodynamically stable on arrival with a finger stick glucose of 121 gm%. Physical examination was unremarkable except for dry mucus membranes. His laboratory results on arrival are shown in Table 1. His serum osmolar gap was within the normal range. He was treated insulin drip per DKA protocol and gap was closed, the patient was clinically and biochemically back to baseline, and he was discharged home. Delayed diagnosis of normoglycemic diabetic ketoacidosis (DKA) in adults with diabetes treated with multiple antidiabetic drugs (eg, sodium-glucose cotransporter-2 [SGLT-2] inhibitors) can potentially increase morbidity and mortality. Patient education in terms of symptoms and signs, physician awareness of early recognition of ketoacidosis in the setting of paradoxically normal or near-normal blood glucose levels in these patients is the primary focus of this case study. This is paradoxical DKA because theoretically patient is not meeting one of the criteria for DKA which include triad of hyperglycemia, Ketoacidosis with widened anion gap, Ketonemia. This is a short case report of presumed SGLT-2 inhibitor euglycemic diabetic ketoacidosis. The main teaching point is recognition and early diagnosis of this issue when multiple diabetic medications are present with the absence of hyperglycemia. This is, by current definition, not DKA because theoretically, the patient does not meet one of the criteria for DKA as the patient was apparently not hyperglycemic, albeit with, ketoacidosis and widened anion gap. (ketonemia).
