Serum lipoprotein changes after prolonged intralipid infusion in malnourished haemodialysis patients

Fat emulsions have been shown to be on efficient source of energy support in malnourished haemodialysis patients. This work was conducted in order to study the effect of prolonged intralipid infusion, during dialysis, on lipid metabolism. The following fasting serum parameters were measured before and after a 1 month infusion of 20% Intralipid (67 kJ/kg body wt/dialysis) in 10 malnourished patients undergoing dialysis: total cholesterol, triglycerides, phospholipids, HDL-cholesterol, LDL-cholesterol, HDL2-cholesterol, HDL3-cholesterol, apolipoproteins A-I, A-II, A-IV, C-II, C-III, and lipoproteins A-I, A-I A-II, EB and (a). After prolonged lipid infusion, the apoprotein B (p < 0.05) and C-II (p < 0.005) increased suggesting a triglyceride transport activation. Apolipoprotein A-I (p < 0.05) and lipoprotein A-I (p < 0.05) decreased without a change in total cholesterol. Lipoprotein (a) decreased in each case (p < 0.005), suggesting a reduction of its related risk of atherogenesis.
