Increased levels of HDL-cholesterol and apolipoprotein A-I after intensified insulin therapy for diabetes.
Sixteen subjects with insulin-dependent diabetes mellitus were studied to determine whether changes in plasma lipids and apolipoproteins follow intensified control using preprandial doses of regular insulin with an additional dose of NPH insulin before bedtime. The mean total dialy dose of insulin was increased from 1.03 +/- 0.09 to 1.17 +/- 0.44 units/kg throughout the six-month period. Levels of HDL-cholesterol and apolipoprotein A-I increased without significant changes in hemoglobin A1 (HbA1), triglyceride, or cholesterol. These findings suggest that increases in HDL-cholesterol and apolipoprotein A-I were a result of the intensified insulin delivery.
