[Effect of clofibrate on lipoprotein-lipids in patients with type IV hyperlipoproteinaemia (author's transl)]

The effect of clofibrate treatment (1.5 g/day for four weeks) on triglycerides, cholesterol and phospholipids in very low density lipoproteins (VLDL), low density lipoproteins (LDL) and high density lipoproteins (HDL) was investigated in 12 patients with type IV hyperlipoproteinaemia. The decrease of serum triglycerides was due to the reduction of VLDL-triglycerides. Furthermore, LDL-hypertriglyceridemia was normalised by clofibrate. -- There existed a significant decrease of VLDL- und HDL-cholesterol as well as of VLDL-phospholipids. The changes in LDL-cholesterol and LDL-phospholipids by clofibrate depended on their initial concentrations which were negatively correlated to the serum triglycerides before treatment. -- The normalisation of lipid concentrations in VLDL and LDI could be explained by a stimulated delipidation of the apo B-lipoproteins.
