Eight patients were studied for lipoprotein profiles over a period of 3–7 weeks. Four patients received total parenteral nutrition (TPN), including 1000 ml/day of Intralipid 10%. Three patients received fat‐free TPN, and one patient was tube fed 1000 ml/day of Intralipid 10% enterally. Fat‐free TPN lowered plasma lipid, especially low density lipoprotein (LDL) and high density lipoproteins (HDL). On the other hand, intravenous administration of Intralipid 10% caused a marked increase of LDL, together with increases of phospholipid and cholesterol, especially free cholesterol. Triglyceride, VLDL, and HDL remained within the normal range in this group. Enteral administration of the same amount of Intralipid 10% did not cause a rise of LDL. Lipid composition of the increased LDL approximated that of lipoprotein X with the intravenous Intralipid 10%. From these findings, we suggest that phospholipids in Intralipid 10% formed abnormal LDL as the result of mobilization of cholesterol from extravascular tissues, when administered intravenously.
