Diabetic ketoacidosis presenting with pseudonormoglycemia in a 15-year-old girl with type 1 diabetes mellitus

Abstract

Pseudonormoglycemic diabetic ketoacidosis (DKA) is a rare condition and has been reported only in a few adult patients. We present a 15-year-old girl with a 9-year history of type 1 diabetes who presented with euglycemic and extreme hypertriglyceridemia. The acidosis and hypertriglyceridemia resolved with intravenous insulin therapy and rehydration. Hyperlipidemia was the apparent cause of pseudonormoglycemia in this patient. The findings in the present case demonstrate that also in children, DKA can rarely occur without abnormal blood glucose levels. Assessment of the acid-base status, urinary glucose, and ketone readings is therefore important in all diabetic patients who are unwell at admission and have normal glucose levels. In such patients, hyperlipidemia may cause pseudonormoglycemia. An awareness of this rare treatable life-threatening condition is important. © Journal of Clinical Research in Pediatric Endocrinology, Published by Galenos Publishing.
