Abstract
Familial type III hyperlipoproteinemia is characterized by the presence of elevated plasma levels of very low density lipoproteins (VLDL) which contain an increased amount of cholesterol and by the presence of a significant amount of lipoproteins with an intermediate density between that of VLDL and low density lipoproteins (LDL); the intermediate density lipoproteins, designated IDL or Lp III, have a slower electrophoretic migration rate than VLDL, and are found in the ultracentrifugal top fraction as a contaminant. Classically, the diagnosis of type III is based on the demonstration of beta-migrating lipoproteins in the ultracentrifugal top fraction (density <1.006), thus "floating beta-lipoprotein". More recently, it has been proposed that an elevated VLDL-cholesterol to triglyceride ratio is diagnostic of the disorder. In the present report, we have compared the two methods for their diagnostic value and have concluded that the chemical index definition is the more reliable method for the diagnosis of type III hyperlipoproteinemia.
