Hypertension Despite Dehydration in an Adolescent with Diabetic Ketoacidosis

Abstract

In general, information on blood pressure changes in diabetic ketoacidosis in paediatric population is very scarce. Our aim was to report a case of severe DKA in an adolescent girl who unexpectedly had hypertension rather than hypotension. A 17-year-old girl presented in our Children’s Emergency Unit with complaints of excessive eating for 6 weeks, excessive urination for 2 weeks, fever for 1 week, vomiting for 4 days, difficulty with breathing for one day and unresponsiveness to calls for 3 hours. She had moderated to severe dehydration but no hypotension. Laboratory findings included hyperglycaemia (random blood glucose 20.8 mmo/L; 347 mg/dl), acidosis (serum bicarbonate 5 mmol/L), ketonuria 2+; glycosuria 2+, and urine specific gravity of 1.015. At admission, the blood pressure was 100/60 mmHg but progressively rose to 140-180/80-100 mmHg by the third day from admission. A significant hypertension can occur in children and adolescents admitted for severe DKA despite the presence of dehydration. Therefore, the attending physician should be aware of this possibility.
