Familial Type IV Hyperlipoproteinemia

Abstract
A 17-year-old girl with asymptomatic hyperlipemia was found to have a Type IV hyperpre-beta-lipoproteinemia. The diagnosis was established by measurement of fasting triglycerides and plasma post-heparin lipolytic activity as well as determination of lipoprotein patterns by electrophoresis and analytical ultracentrifugation. After one week on a 90 per cent carbohydrate diet, serum triglycerides demonstrated an exaggerated rise.
