A previous study of low density lipoprotein metabolism by cultured cells focused on the metabolism of normal lipoproteins in vitro by fibroblasts isolated from diabetic patients. No abnormalities were found. We have followed the opposite approach. Using normal human fibroblasts as test cells we compared the metabolism in vitro of low density lipoproteins isolated from diabetic patients before and after metabolic control. We found a significant decrease (p less than 0.02) in internalization and degradation of low density lipoproteins isolated from diabetic patients before metabolic control when compared with those isolated from normal control subjects or from the same patients after metabolic control. The observed changes were mainly apparent in intracellular degradation. To evaluate whether the observed differences in low density lipoprotein behaviour were correlated with lipid or apolipoprotein composition, we measured cholesterol, triglyceride, apolipoprotein B and total protein levels in the low density lipoproteins tested. A significant decrease (p less than 0.05) of the triglyceride/protein ratio was found in post-control low density lipoproteins suggesting that a high triglyceride content may interfere with low density lipoprotein metabolism. The present study represents the first observation that metabolic control in diabetes mellitus can alter low density lipoprotein-cell interaction and suggests a possible mechanism for the enhanced incidence of atherosclerosis in diabetic patients.
