We have studied the lipoproteins, apolipoproteins, and postheparin lipase activities in an extended pedigree with familial hepatic lipase deficiency. A deficiency of hepatic lipase was found in three of five brothers and in one of their children. Triglyceride enrichment of low density and high density lipoproteins was identified as the constitutive phenotype. beta-very low density lipoprotein w...

There are no adequate data that evaluate the safety and effectiveness of lowering triglyceride levels in infants. The authors report a neonate affected by familial hyperchylomicronemia, While being investigated for sepsis the serum sample obtained for blood counts was discovered to be lipaemic and the case was subsequently investigated for dyslipidemia. Based on this very abnormal lipid profile...

Postheparin plasma lipolytic activity consists of two hydrolytic activities, hepatic triglyceride lipase and lipoprotein lipase. These two enzymes were separated and partially purified by means of ammonium sulfate precipitation and affinity chromatography using Sepharose with covalently linked heparin and concanavalin A, respectively. Antibodies were produced against hepatic triglyceride lipase...

Angiopoietin-like protein 3 (ANGPTL3) is a secretory protein regulating plasma lipid levels via affecting lipoprotein lipase- and endothelial lipase-mediated hydrolysis of triglycerides and phospholipids. ANGPTL3-deficiency due to loss-of-function mutations in the ANGPTL3 gene causes familial combined hypobetalipoproteinemia (FHBL2, OMIM # 605019), a phenotype characterized by low concentration...

A baby girl, born by normal spontaneous vaginal delivery with birth weight 3.845kg, was admitted for neonatal jaundice on day 2 of life. Her mother had maternal gestational diabetes on diet control. Her father was newly diagnosed with hyperlipidaemia on health screen and was put on diet control. There was no consanguinity. Her serum bilirubin level on admission was 186mmol/L with normal liver f...

This thesis is based on the following original articles, which are referred to in the text by their Roman numerals. acid content of LDL and lipoprotein metabolism in combined hyperlipidemia and primary moderate hypercholesterolemia. acid content of LDL and its relation to lipid concentrations and metabolism of LDL and cholesterol. Submitted. increases the sialic acid content of LDL in hyperchol...

A 5-yr old male proband and his sister have had hypertriglyceridemia and hepatosplenomegaly since birth. When studied on a metabolic ward, they demonstrated rapid decreases in serum triglycerides on 3 g fat/day diets. Oral glucose tolerance tests were normal. Postheparin lipolytic activity (PHLA) against chylomicrons was virtually absent in both children whereas the mother and a normolipemic si...
