Abstract

Type I insulin-dependent diabetic patients have an increased risk of atherosclerotic vascular disease that may be determined in part by their tendency to develop circulating lipid and lipoprotein abnormalities. The occurrence of such findings in asymptomatic ambulant Type I patients with mild or moderate hyperglycemia might suggest that conventional methods of insulin treatment are as inefficient at normalizing lipid abnormalities as they are in achieving euglycemia. It would then be important to ascertain whether intensive methods of insulin treatment effectively normalized lipid levels. Ten insulin-dependent young adult diabetic patients were studied on a conventional insulin treatment regimen and then at two-monthly intervals for a six-month period during which they were managed by three different intensified insulin treatment regimens. Plasma glucose levels improved substantially (p<0.001) after two months of intensified therapy (106±4 mg/dl) and did not change significantly thereafter for the remaining four months of intensified insulin treatment. Apart from a short-lived decrease in total, LDL and HDL-cholesterol after two months of intensified treatment (baseline total triglyceride 116±13 mg/dl, total cholesterol 174±16 mg/dl, HDL-cholesterol 46±3 mg/dl). There were no persistent changes in serum lipids, lipoprotein cholesterol or in levels of their major apoproteins A-I, A-II and B. These findings support the contention that, despite moderate hyperglycemia, conventional insulin treatment may be adequate to maintain normal lipid levels. In such circumstances achievement of euglycemia by intensified insulin therapy leads to little change in circulating lipid and lipoprotein values.
