Glycemic control and serum lipoproteins after total pancreatectomy.
Carbohydrate and lipid metabolism were studied in 10 patients who had undergone total pancreatectomy. The results were compared with Type I diabetic patients and normal subjects, all of whom were matched for age, sex and weight. At the same level of glycemic control, the daily need for insulin was significantly lower in the patients with pancreatogenic diabetes than in those with Type I diabetes. Concentrations of serum total VLDL and HDL triglyceride were higher in the pancreatectomized patients than in the diabetic or normal controls, whereas concentrations of serum total and LDL cholesterol were significantly lower. The composition of the VLDL, LDL and HDL particles was abnormal in the totally pancreatectomized patients as all three lipoprotein fractions were enriched in triglyceride. HDL2 cholesterol was similar in the totally pancreatectomized patients to that in the other two groups but HDL3 cholesterol was lower. Postheparin plasma lipoprotein lipase and hepatic lipase activities were normal. It is concluded that in totally pancreatectomized patients the changes in the lipoprotein profile on reflect more the action of various confounding factors, i.e. malabsorption, continuance of alcohol abuse and dietary changes than the impact of the diabetes itself.
