The case of a 6-year-old girl with severe hyperlipoproteinemia and chronic renal failure that developed after hemolytic uremic syndrome (HUS) is reported. The patient was homozygous for apolipoprotein (apo) E2, and her very-low-density lipoprotein (VLDL)-cholesterol/serum-triglyceride (TG) ratio of 0.63 was unusually high. She was consistently diagnosed to have type III hyperlipoproteinemia (HLP). This is the first report of type III HLP in a child with chronic renal disease.
