[Comparative studies of the metabolism of MCT/LCT and LCT emulsions in diabetics].

In 7 moderately overweight non-insulin dependent diabetics with slightly elevated triglyceride levels, disappearance rates of MCT/LCT- und LCT-emulsions were compared. 5 metabolically healthy volunteers served as control. During a 3-hour lipid infusion, serum triglycerides reached a steady state with both emulsions in the healthy controls, whereas in diabetic patients, steady state triglyceride levels were seen only with MCT/LCT. After the end of the lipid infusion, the longest half life value concerning the decline of triglyceride levels was found with LCT in diabetics, while significantly shorter and quite similar half life values were found with LCT in healthy controls and MCT/LCT in diabetics. The shortest half life for serum triglycerides was expectedly found in healthy controls. According to these data, parenteral nutrition with lipids in states of disturbed glucose and lipid metabolism--if necessary--should preferentially be done with MCT/LCT emulsions.
