Poorly controlled type 2 diabetes complicated by an episode of severe hypertriglyceridaemia-induced pancreatitis.

A 23-year-old woman with a history of type 2 diabetes and non-compliance presented to the emergency department with abdominal epigastric pain and nausea. Laboratory examination revealed a mild ketoacidosis while an abdominal CT scan performed the following day demonstrated a severe acute pancreatitis of the body and tail (Balthazar grade E) despite normal amylase serum levels on admission. The presence of a lactescent serum was the clue to an extremely high triglyceride level (>10 000 mg/dl) causing the pancreatitis. The hypertriglyceridaemia itself was attributed mainly to the diabetic ketoacidosis. There was no family history of hypertriglyceridaemia. The triad consisting of diabetic ketoacidosis, hypertriglyceridaemia and acute pancreatitis is an unusual presentation of poorly controlled diabetes which can occur in type 1 as well as type 2 diabetic adults and children. Treatment with intravenous insulin and hydration successfully resolved the ketoacidosis and hypertriglyceridaemia and reversed the episode of acute pancreatitis.
