title: Plasma lipids and apolipoproteins in a 13-year-old boy with diabetic ketoacidosis and extreme hyperlipidemia.
abstract: A 13-year-old boy with untreated diabetes presented in severe ketoacidosis (DKA) for the first time with an initial triglyceride (TG) level of 14,461 mg/dl. Serial blood samples were drawn to determine the interrelationships of changes in lipids and apolipoproteins during treatment with insulin and intravenous fluids. The TG level declined to 122 mg/dl in 7 days concomitant with a lowering of apolipoproteins C-II, C-III, E, D, and F. Further observations suggested that the TG-rich lipoproteins underwent degradation associated with a decline in the levels of apolipoproteins associated with very low density lipoprotein (VLDL) in contrast to an increase in high density lipoprotein-cholesterol (HDL-C), ApoA-I and ApoA-II. ApoB and low density lipoprotein cholesterol (LDL-C) were increased transiently. Subsequent therapy with continuous subcutaneous insulin infusion (CSII) were effective in maintaining glucose homeostasis and normolipidemia for 6 months.
