Diabetic ketoacidosis occurring with lower blood glucose levels in pregnancy: a report of two cases.

BACKGROUND: Euglycemic diabetic ketoacidosis (DKA) during pregnancy is an unusual condition, but it can occur with normal or modest elevations in blood glucose levels. It is usually a complication of type I diabetes.

CASES: We report two cases of euglycemic DKA, in type II diabetes mellitus and in gestational diabetes. Both patients showed blood glucose levels up to 9 mmoL/L (164 mg/dL), ketonuria and metabolic acidosis. They responded to initiation of correct insulin dosages.

CONCLUSION: Euglycemic DKA in pregnancy may occur with type II diabetes or in gestational diabetes and requires prompt recognition and treatment.
